THE STUDY INTO THE KNOWLEDGE LEVEL AND CAUSES OF HOSPITAL ACQUIRED INFECTIONS AMONG PATIENTS AT SUNTRESO GOVERNMEN HOSPITAL BY WIREDU RICHARD ADUTWUM RESEARCH INSTITUTE SUNYANI- GHANA JUNE, 2020 ABSTRACT The main objectives of the study was to determine the level knowledge and causes of hospital acquired infection. The study mirrors the study in the following specifics. This study take into accounts all patient visiting Suntreso Government Hospital in Kumasi Atonsu in the Kumasi Municipal Assembly (KMA). Informed consent was obtained from all study participants and duly acknowledged by participants in agreement to the study. The research comprises of five primary segments. Purposive sampling technique which is probability sampling methods was used. A total number of 100 Hospital Acquired Infection patients were picked as the sample size. The respondent were made to answer questionnaires on the knowledge level and prevention of HAIs and also in other to ascertain the cause of HAIs the respondents were interviewed. Respondents demographic were sampled to aid the research bring clarity to the study. Data were analysed with descriptive and inferential statistics using Statistical Package for Social Sciences (SPSS), version 22. Descriptive data were presented in tables by mean, standard deviation, and percentage where it was needed. In conclusion, majority of HCWs have knowledge and understanding of HAIs' preventive methods However, implementation of these knowledge through compliance of preventive methods must be encourage among patients. Basing on the finding of this survey, the following recommendations were made: Radio interviews should be done on HAIs so to increase the knowledge level of the general public. Gloves Sterile gloves should be worn after hand hygiene procedure while touching mucous membrane and non-intact skin and performing sterile procedures (2A) e.g. arterial, central line and Foley catheter insertion i TABLE OF CONTENT Contents CHAPTER ONE ...................................................................................................... 1 INTRODUCTION ................................................................................................... 1 1.0 Background of the Study ..................................................................................... 1 1.1.

A prevalent survey in 2002 conducted under the auspices of the World Health Organization [WHO] (2009) in 55 hospitals of 14 countries representing 4 WHO regions (Europe, Eastern Mediterranean, South-East Asia and Western Pacific) showed an average of 8.7% of hospital patients had HAIs. Hecker et al (2003) defined Hospital Acquired Infections (HAIs) as those infections that were not present at the time of patient’ hospitalization in a hospital or other medical institutions and have been acquired after hospitalization. Estimate of the annual cost of treatment for HAIs ranges from $4.5 billion to $11 billion and upwards contributed to 88 000 deaths in the U.S. in 1995 (Isbary, & Stolz, 2012). HAIs add to the imbalance between resource allocation for primary and secondary healthcare by directing scarce funds to the management of potentially preventable conditions. Razzak and Kellermann, (2002) indicated that this is particularly important in developing countries where very little amount of resources are available for use for an unbearable number of patients. It is believed that one third of nosocomial infections are considered preventable and that as many as 92% of deaths from hospital infections could be prevented. It is extrapolated that the rate of incidence of HAIs in Ghana is approximately 152 000 out of 20.7 million people. Raka et al. (2003) published the first article in Kosovo in 1 the field of HAIs, which reported a mortality rate of 31% among new-borns, the prevalence of hospital infections in UCCK was 17.4%. In 2010, a data report for HAIs cases among 2.473 hospitals showed an increased number of infections associated with the use of medical equipment, most of which were displayed in surgical units (Badia et al., 2017). Also, other researchers reported that patients who underwent surgical procedures had a greater chance of developing HAIs, compared to other patients. Infection Control is the responsibility of the care nurses and represents an integral element of patient safety programs. An earlier study on HAIs at the Volta regional hospital in Ghana by Ocran and Tagoe, (2014) isolated a total of 187 (85.8%) bacteria (made up of 55.5% non-pathogenic and 30.3% pathogenic organisms from fomites in the Volta regional hospital, Volta Region, Ghana). A recent investigation on the potential sources of transmission of HAIs in the central regional hospital, cape coast, Ghana showed very high bacterial isolates with a mean count of 1×10. A nosocomial infection is contracted because of an infection or toxin that exists in a certain location, such as a hospital. People now use nosocomial infections interchangeably with the terms health-care associated infections (HAIs) and hospitalacquired infections. For a HAI, the infection must not be present before someone has been under medical care. One of the most common wards where HAIs occur is the intensive care unit (ICU), where doctors treat serious diseases. About 1 in 10 of the people admitted to a hospital will contract a HAI. They’re also associated with significant morbidity, mortality, and hospital costs. As medical care becomes more complex and antibiotic resistance increases, the cases of HAIs will grow. The good news is that HAIs can be prevented in a lot of healthcare situations. 2 Bickley and Szilagyi, (2012) said many doctors can diagnose a HAI by sight and symptoms alone. Inflammation and/or a rash at the site of infection can also be an indication. Infections prior to your stay that become complicated don’t count as HAIs. But you should still tell your doctor if any new symptoms appear during your stay. Infection may be acquired endogenously or from one's own body flora, and exogenously or from patients, staff and the hospital environment. Contact, especially with inadequately washed hands of the staff, plays an important role in hospital crossinfections. Hospital acquired infections are caused by various factors. Some of the common ones include improper hygiene. Patients can get infections of diseases such methicillin resistant staphylococcus aureus (MRSA), respiratory illnesses and pneumonia from hospital staff and their visitors (Bereket, et al., 2012). Also Doctors and nurses who do not practice basic hygienic measures such as washing hands before attending to patients may spread MRSA among them. Other infections are due to injections. There are cases where some hospital staffs do not give injections properly. Infections like HIV and hepatitis B can be as a result of contaminated blood due to sharing syringes and needles between patients when injecting medication into their intravenous lines. Hospital acquired infections may also be as a result of torn or improperly bandaged incisions during surgeries. These incisions get contaminated with bacteria from the skin or the surrounding environment. Similarly, bacteria can be introduced into the patient's body by contaminated surgical equipment. Also breathing machines such as ventilators can spread infections like pneumonia among patients using them. Staffs that do not use the proper infection control measures tend to contaminate these machines with germs. There are also cases where people on breathing machines are unable to cough and expel germs from their lungs. 3 Treatments for these infections depend on the infection type. Your doctor will likely recommend antibiotics and bed rest. Also, they’ll remove any foreign devices such as catheters as soon as medically appropriate. To encourage a natural healing process and prevent dehydration, your doctor will encourage a healthy diet, fluid intake, and rest. HAIs are a significant cause of illness and death — and they can have devastating emotional, financial, and medical consequences. Bennett and Brachman, (1998) at any given time, about 1 in 25 inpatients have an infection related to hospital care. These infections lead to the loss of tens of thousands of lives and cost the U.S. health care system billions of dollars each year. Focused HAI prevention activities and improved antibiotic use are synergistic. Addressing these challenges together can amplify the impact of efforts to slow the development of antibiotic resistance. Zhu et al. (2013) on all sampled surfaces, 46.1% pathogenic bacterial isolates showed extensive resistant profile to commonly prescribed antibiotics. This suggests a high potential of HAIs, thus assessing knowledge and attitude of workers and users of these facilities on HAIs is needed. The objectives of this current study were to assess the knowledge of patients on HAIs, sources of knowledge of these infections, sources of these infections and their attitude to prevent these infections. Those will help hospital authorities and information services improve information dissemination as well as adopt more pragmatic approach in helping reduce such infections. 1.1. Problem Statement Patients are exposed to varieties of microorganisms during hospitalization. Hospital acquired infections or diseases are on the rise. Patients present with one condition to the hospital which is treated after their stay, but unfortunately go home with a different condition. 4 Although infection is most prevalent in patients upon admission, health care workers also act as potential vectors for pathogenic agents. Hospitals provide a favourable transmission pathway for the spread of hospital acquired infections (nosocomial), owing partly to poor infection control practices among health workers on one hand and overcrowding of patients in most clinical settings on the other (McAlister et al., 1999). Due to the low knowledge level and occurrence of nosocomial infections recorded above there is the need for research to be done about it to find the problem behind causes and the knowledge level. 1.2 Research Objectives The main objectives of the study is to determine the level knowledge and causes of hospital acquired infection. The study mirrors the study in the following specifics 1. To assess the patients knowledge level on Hospital Acquired Infection 2. To identify the causes of Hospital Acquired Infection 3. To point out some of the preventive measures of Hospital Acquired Infections 1.3 Research Questions 1. What is the knowledge level of patient about hospital acquired infection? 2. What are the causes of hospital acquired infection? 3. What are the preventive measures of hospital acquired infections? 1.4 Justification of the Study The purpose of the study will help educate the male patient on the knowledge level on hospital acquired infections. The purpose of the study will help serve as baseline data to measure the progress of the condition. The study seeks to help researchers to understand and have more insight about the condition under study. 5 1.5 Scope/Limitation to the Study This study will take into accounts all patient visiting Suntreso Government Hospital in Kumasi – Atonsu in the Kumasi Municipal Assembly (KMA). Informed consent will be obtained from all study participants and duly acknowledged by participants in agreement to the study. Since each research has its constraints, the compilation of information, data processing and evaluation will be a significant constraint. The greatest limitation will be on the questionnaire, its interpretations to the illiterate, since the researchers are student, we will combine both academic and the research, and the time needed will be very limited. Another limitation is budgetary constraints, since the researchers are student. 1.6 Organisation to the Study The research comprises of five primary segments, Chapter 1 comprises the background of the study, the declaration of problems, objectives and research issues, the survey's meaning and scope/limitation, Chapter 2 Review the relevant topics and literature in related to empirical review. Chapter 3 examines how the research will be done by examining the methodology of studies. Chapter 4 examines the data's assessment and discussion. Chapter 5 is the final section in which the results, conclusions, suggestions and fields for further studies are summarised. 6 CHAPTER TWO LITERATURE REVIEW 2.0 Introduction This section reviewed document relating to the topic the knowledge level and causes of hospital acquired infection among patient at Suntreso Government Hospital. Literature was organized based on the knowledge level and causes of hospital acquired infection. The literature review is done with the objectives of the research in mind. The primary factors of the research are discussed in this section. 2.1 Concept of Hospital Acquired Infection In the 1960s, growing concern over hospital acquired infection stimulated considerable investment by US hospitals in the variety activities aimed at infection surveillance and control to prevent these nosocomial infections. However there was no comprehensive description of the type of programs in existence.in 1970s an international conference on nosocomial was held at the center for disease control at Atlanta. (Streiff, et al, 2016). Although infection is most prevalent in patients upon admission, health care workers also act as potential vectors for pathogenic agents. Hospitals provide a favourable transmission pathway for the spread of nosocomial infections, owing partly to poor infection control practices among health workers on one hand and overcrowding of patients in most clinical settings on the other. Yasir (2009) indicated that a nosocomial infection is contracted because of an infection or toxin that exists in a certain location, such as a hospital. People now use nosocomial infections interchangeably with the terms health-care associated 7 infections (HAIs) and hospital-acquired infections. For a HAI, the infection must not be present before someone has been under medical care. One of the most common wards where HAIs occur is the intensive care unit (ICU), where doctors treat serious diseases. About 1 in 10 of the people admitted to a hospital will contract a HAI. They’re also associated with significant morbidity, mortality, and hospital costs. As medical care becomes more complex and antibiotic resistance increases, the cases of HAIs will grow. The good news is that HAIs can be prevented in a lot of healthcare situations. Read on to learn more about HAIs and what they may mean for you. 2.1.1 Symptoms of Nosocomial Infections Gordts e al. (2010) for a HAI, the infection must occur: 1. Up to 48 hours after hospital admission 2. Up to 3 days after discharge 3. Up to 30 days after an operation 4. And in a healthcare facility when someone was admitted for reasons other than the infection Fitzpatrick (1988) indicated that Symptoms of HAIs will vary by type but the most common types of HAIs are: urinary tract infections (UTIs), surgical site infections, gastroenteritis meningitis and pneumonia. The symptoms for these infections may include: discharge from a wound, fever, and cough, shortness of breathing, burning with urination or difficulty urinating, headache, nausea, vomiting and diarrhoea. People who develop new symptoms during their stay may also experience pain and irritation at the infection site. Many will experience visible symptoms. 2.1.2 Causes Nosocomial Infections Schmidt et al., (1994) Bacteria, fungus, and viruses can cause HAIs, Bacteria alone cause about 90 percent of these cases. Many people have compromised immune 8 systems during their hospital stay, so they’re more likely to contract an infection. Some of the common bacteria that are responsible for HAIs are shown in Table 2.1 Table 2.1 the common bacteria that are responsible for HAIs Bacteria Infection type Staphylococcus aureus (S. aureus) blood Escherichia coli (E. coli) UTI Enterococci blood, UTI, wound Pseudomonas aeruginosa (P. kidney, UTI, respiratory aeruginosa) Source: Schmidt et al. 1994 Of the HAIs, P. aeruginosa accounts for 11 percent and has a high mortality and morbidity rate. Bacteria, fungi, and viruses spread mainly through person-to-person contact. This includes unclean hands, and medical instruments such as catheters, respiratory machines, and other hospital tools. HAI cases also increase when there’s excessive and improper use of antibiotics. This can lead to bacteria that are resistant to multiple antibiotics. 2.1.3 Prevention of Hospital Acquired Infections Controlling nosocomial infection is to implement QA/QC measures to the health care sectors, and evidence-based management can be a feasible approach. For those with ventilator-associated or hospital-acquired pneumonia, controlling and monitoring hospital indoor air quality needs to be on agenda in management. Whereas for nosocomial rotavirus infection, a hand hygiene protocol has to be enforced. Zimlichman et al., (2013) to reduce HAIs, the state of Maryland implemented the Maryland Hospital-Acquired Conditions Program that provides financial rewards and penalties for individual hospitals based on their ability to avoid HAIs. Despite sanitation protocol, patients cannot be entirely isolated from infectious agents. Furthermore, patients are often prescribed antibiotics and other antimicrobial drugs 9 to help treat illness; this may increase the selection pressure for the emergence of resistant strains. Common ways of Preventing of Hospital Acquired Infections as discussed by Kelly, and Monson, 2012 as follows: Sterilization: Sterilization goes further than just sanitizing. It kills all microorganisms on equipment and surfaces through exposure to chemicals, ionizing radiation, dry heat, or steam under pressure (Block, 2001) Isolation: Garner, J.S. and Hospital Infection Control Practices Advisory Committee (1996) Isolation is the implementation of isolating precautions designed to prevent transmission of microorganisms by common routes in hospitals. Because agent and host factors are more difficult to control, interruption of transfer of microorganisms is directed primarily at transmission for example isolation of infectious cases in special hospitals and isolation of patient with infected wounds in special rooms also isolation of joint transplantation patients on specific rooms. Antimicrobial surfaces: Madkour et al., (2008) Micro-organisms are known to survive on inanimate ‘touch’ surfaces for extended periods of time, this can be especially troublesome in hospital environments where patients with immunodeficiency are at enhanced risk for contracting nosocomial infections. A number of compounds can decrease the risk of bacteria growing on surfaces including: copper, silver, and germicides. Surface sanitation: sanitizing surfaces is part of nosocomial infection in health care environments. Modern sanitizing methods such as Non-flammable Alcohol Vapor in Carbon Dioxide systems have been effective against gastroenteritis, MRSA, and influenza agents. 10 Frank and Chmielewski (1997) Use of hydrogen peroxide vapour has been clinically proven to reduce infection rates and risk of acquisition, hydrogen peroxide is effective against endospore forming bacteria, such as Clostridium difficile, where alcohol has been shown to be ineffective Ultraviolet cleaning devices may also be used to disinfect the rooms of patients infected with Clostridium difficile or MRSA after discharge Hand washing: Trampuz, and Widmer (2004) Hand washing frequently is called the single most important measure to reduce the risks of transmitting skin microorganisms from one person to another or from one site to another on the same patient. Washing hands as promptly and thoroughly as possible between patient contacts and after contact with blood, body fluids, secretions, excretions, and equipment or articles contaminated by them is an important component of infection control and isolation precautions (Garner et al., 1983). Aragon et al., (2005) improving patient hand washing has also been shown to reduce the rate of nosocomial infection. Patients who are bed-bound often do not have as much access to clean their hands at mealtimes or after touching surfaces or handling waste such as tissues. By reinforcing the importance of hand washing and providing sanitizing gel or wipes within reach of the bed, nurses were directly able to reduce infection rates. All visitors must follow the same procedures as hospital staff to adequately control the spread of infections. Moreover, multidrug-resistant infections can leave the hospital and become part of the community flora if steps are not taken to stop this transmission. It is unclear whether or not nail polish or rings affected surgical wound infection rates 11 Gloves: In addition to hand washing, gloves play an important role in reducing the risks of transmission of microorganisms (Allegranzi and Pittet, 2009). Gloves are worn for three important reasons in hospitals. First, they are worn to provide a protective barrier for personnel, preventing large scale contamination of the hands when touching blood, body fluids, secretions, excretions, mucous membranes, and non-intact skin. In the United States, the Occupational Safety and Health Administration has mandated wearing gloves to reduce the risk of bloodborne pathogen infections (Twitchell and Wachs, 2003) Secondly, gloves are worn to reduce the likelihood that microorganisms present on the hands of personnel will be transmitted to patients during invasive or other patientcare procedures that involve touching a patient's mucous membranes and nonintact skin. Third, they are worn to reduce the likelihood that the hands of personnel contaminated with micro-organisms from a patient or a fomite can transmit those micro-organisms to another patient. In this situation, gloves must be changed between patient contacts, and hands should be washed after gloves are removed. Girou et al., (2004) argues that wearing gloves does not replace the need for hand washing due to the possibility of contamination when gloves are replaced, or by damage to the glove. Doctors wearing the same gloves for multiple patient operations presents an infection control hazard. 2.1.4 Persons Mostly Affected By Nosocomial Pathogens Nosocomial infections typically affect patients who are immune compromised because of age, underlying diseases, medical or surgical treatments. Aging of our population and increasingly aggressive medical and therapeutic interventions 12 including implanted foreign bodies and organ transplantations have created a cohort of particularly vulnerable persons (Weinstein, 1991). As a result, the highest infection rates are among intensive care unit (ICU) patients. Nosocomial infection rates in adult and pediatric ICUs are approximately three times higher than elsewhere in hospitals. The sites of infection and the pathogens involved are directly related to treatment in ICUs. In these areas, patients with invasive vascular catheters and monitoring devices have more bloodstream infections due to coagulase-negative staphylococci. Studies have shown that cases of occult bacteremia in ICU patients are probably due to vascular access-related infections (Weinstein and Fridkin, 2003). 2.1.5 The Emerging Trends of Nosocomial Infections Three major factors are involved in nosocomial infections. The first is long-term antimicrobial use in hospitals and other health care facilities. The increased concern about gram-negative bacilli infections in the 1970s to 1980s led to increased use of cephalosporin antibiotics. As gram-negative bacilli became resistant to earlier generations of cephalosporin antibiotics, newer generations were developed (File, 1999). Widespread use of cephalosporin antibiotics is often cited as a cause of the emergence of enterococci as nosocomial pathogens. Methicillin-resistant Staphylococcus aureus (MRSA), perhaps also in response to extensive use of cephalosporin antibiotics became a major nosocomial threat. Widespread empiric use of Vancomycin in response to concerns about MRSA and for treatment of vascular catheter associated infection by resistant coagulase-negative Staphylococci was the major initial selective pressure for Vancomycin-resistant Enterococci. Use of antimicrobial drugs in long-term care facilities such as ambulatory and extended care settings and transfer of patients between these facilities and hospitals have created a large reservoir of resistant strains in nursing homes (Taconneli et al., 2008). 13 Many hospital personnel also fail to follow basic infection control rules such as hand washing between patient contacts. In intensive care units, asepsis is often overlooked in the rush of crisis care (Weinstein, 1991). Lastly, the long-term use of vascular or other device-related care in immunosuppressed patients has led to higher prevalence of bloodstream infections and ventilator-associated pneumonia (Garland, and Uhing, 2009). 2.2 Empirical Review It examines past empirical studies to answer a specific research question. Empirical research is based on phenomena observed and measured and derives knowledge not from theory or belief but from actual experience (Spilka, 2002). In this section, the study examines the study done in the area of EBF in terms of the objective of the study. 2.2.1 Studies on the Knowledge Level of Patient about Hospital Acquired Infection Madeo et al. (2008) did A pilot study to investigate patients reported knowledge, awareness, and beliefs on health care–associated infection. The study used a descriptive study of 110 patients was undertaken utilizing a developed questionnaire to investigate patients' knowledge, perceptions, and beliefs around Hospital Acquired Infection. The results shows that respondents believed they were well aware of the risks of Hospital Acquired Infection before hospital admission, but their knowledge on routes of transmission and prevention of infection was poor. Twenty-eight percent of the respondents were able to name Methicillin-resistant Staphylococcus aureus (MRSA) as contributing to HAIs. Patients' main sources of information about infections were newspapers and television. 14 Sarani et al. (2016) study was conducted to evaluate knowledge, attitude and practice of nurses and patients against HAIs. Their study was conducted using a descriptive cross-sectional on 170 nurses and patients working at teaching hospitals of Zabol, Iran, under the supervision of Zabol University of Medical Sciences in 2014. According to the results, most respondent do not have a good knowledge and practice about infection control despite having an average efficacy. It is also necessary to improve the knowledge of standard precautions, develop programs for HAI control, and hold training courses based on successful educational models. Gikas et al. (2002) the aim of their study was to organize a surveillance of HAI with the participation of the greatest possible number of Greek hospitals, transferring the experience from the local Cretan infection control network in an effort to create a nationwide network. Special attention was paid to recruit all Greek university hospitals in our attempt to expand the study base. The sudy found that the duration of hospitalization, the number of operations, the total number of used devices and invasive procedures were significantly correlated with HAI. Patients have a high level of awareness of the risk of HCAI but have little knowledge about how infections spread or about their prevention these studies found. 2.2.2 Studies on the Causes of Hospital Acquired Infection Thompson et al. (1982) indicated that outbreaks of hospital-acquired infections are caused by methicillin-resistant Staphylococcus aureus, this recognized with increasing frequency in the United States. Two thirds of outbreaks have been cantered in critical care units. Infected and colonized inpatients appear to be the major institutional reservoir, and transient carriage on the hands of hospital personnel appears to be the most important mechanism of serial patient-to-patient transmission. 15 In over 85% of hospitals into which they have been introduced, methicillin-resistant strains of S. aureus have become established as endemic nosocomial pathogens. Murni et al. (2015) in their study reducing hospital-acquired infections and improving the rational use of antibiotics in a developing country which was aimed at investigating the causes and reduction HAIs and antibiotic use. Their study found multifaceted infection control interventions are effective in reducing HAI rates, improving the rational use of antibiotics, increasing hand hygiene compliance, and may reduce mortality in hospitalised children in developing countries. Shurland et al. also in their study tried to identify factors cause Hospital Acquired Infection. The objective of their study was to quantify the clinical impact of methicillin-resistance in Staphylococcus aureus causing infection complicated by bacteremia in adult patients, while controlling for the severity of patients' underlying illnesses. They found that 193 (44%) of the 438 patients had methicillin-resistant S. aureus (MRSA) infection and 114 (26%) died of causes attributable to S. aureus infection within 90 days after the infection was identified. Patients with MRSA infection had a higher mortality risk, compared with patients with methicillin-susceptible S. aureus (MSSA) infections (relative risk, 1.7 [95% confidence interval, 1.3-2.4]; P < .01), except for patients with pneumonia (relative risk, 0.7 [95% confidence interval, 0.41.3]). 2.2.3 Studies on the Preventive Measures of Hospital Acquired Infections According to Peleg and Hooper, (2010) Hospital-acquired infections are a major challenge to patient safety. It is estimated that in 2002, a total of 1.7 million hospitalacquired infections occurred (4.5 per 100 admissions), and almost 99,000 deaths 16 resulted from or were associated with a hospital-acquired infection, making hospitalacquired infections the sixth leading cause of death in the United States; similar data have been reported from Europe. The estimated costs to the U.S. health care budget are $5 billion to $10 billion annually. Approximately one third or more of hospitalacquired infections are preventable. In this discussion Sherwood et al. (1970) define briefly the scope of the problem, explore some of the causes of the unacceptably high prevalence of hospital-acquired infections, evaluate some of the current preventive measures, and speculate on developments that may improve prevention and therapy. They did focused on bacterial infections, although in certain classes of patients other organisms at times may be etiologic. 2.3 Summary of Literature Review The existing works have revealed a lot of information about HAI, IPC, factors causing, Preventive Measures and knowledge on HAIs. It is established that hand washing can minimize microorganisms acquired through contact with body fluid and contaminated surfaces and so can other IPC standard precautions. Existing studies have identified some factors that Causes of Hospital Acquired Infection. 17 CHAPTER THREE METHODOLOGY 3.0 Introduction Wiredu (2019) denoted that the word methodology is a system of specific guidelines and processes for studies and for assessing information allegations. This chapter converses the population and sample size, the research plan, instrumentation, data collection technique and data analysis technique. 3.1 Study Design The objective of this study is to determine the level knowledge and causes of hospital acquired infection among patients. This included examining the knowledge level of patients about hospital acquired infection, to identify the causes of hospital acquired infection and also to point out some of the preventive measures of hospital acquired infections. Therefore, this research was organised in the context of a descriptive research approach. Descriptive research is described as a technique of study that explains the features of the researched population or event. Key informant interviews and focus group discussions were utilised in this study. The qualitative descriptive design describes people’s life experiences regarding a particular phenomenon (Polit & Beck, 2010). Qualitative descriptive design allowed the researchers to achieve the objective of this study. The study will be conducted at Suntreso Government Hospital, and is about 10 minutes’ drive from Kumasi Township. The hospital is found on Sunyani road and it shares boundaries with Sofoline and Abrepo in the Kumasi Metropolitan Assembly (KMA), Ashanti Region. 18 It renders services to the population in Kumasi, especially those residences at Sofoline, Bantam, and Adum and also nearby towns. 3.2 The Population Size Simons (2009) a research population is a survey of a group of people belonging to the over-all population who share a common feature, such as age, sex or other common feature, which is the primary focus of a scientific inquiry. People, individuals, animals, objects can form the population of research. Creswell & Zhang (2009) explicated that population type is in two forms, i.e.: targeted and accessible populations. The population of this work will be drawn from all patients at Suntreso Government Hospital. 3.3 Sampling and Sampling Techniques A sample is a lesser set of a population that is used to draw inferences about the greater set (Simons, 2009). Purposive sampling technique which is probability sampling methods will be used. A total number of 100 Hospital Acquired Infection patients will be pick as the sample size. 3.4 Research Collection Research Instruments are measurement tools (for example, questionnaires, or scales) designed to obtain data on a topic of interest from research subjects (Nicoll, and Beyea, 1997). Research Instruments are measuring instruments for obtaining information from research subjects on a topic of concern. The primary source data were gathered for this study. The study was performed from October 6, 2019, to January 18, 2019, on the sample size of 115 respondent. The respondent were made to answer questionnaires on the knowledge level and prevention of HAIs and also in other to ascertain the cause of HAIs the respondents 19 were interviewed. Respondents demographic were sampled to aid the research bring clarity to the study. 3.5 Validity of the Research Instrument Both the interview guide and the questionnaires were pretested on five patients, three nurses, three and medical officers. The pre-test helped researchers to modify questions for clarity. The pre-test also helped to ensure that the data collected answered the research questions. The questionnaire was self-administered and required about 15 minutes to be completed. The research team had prolonged interactions with the participants to ensure an indepth understanding of emerging findings. Data transcriptions and coding were done by the research team to ensure that the correct experiences and views of the participants were reported. Discussion of themes by the research team was done to ensure correct representations of participants. Study participants were consulted for their comments on themes to make sure it represented their views. 3.6 Ethics Approval and Consent to Participate The permission to conduct the research was undertaken by the competent authorities and the ethics committee within the hospital. All participants had the opportunity to accept or decline their participation in the study. Also they were provided that their ethical rights would be respected, such as anonymously, confidentiality. 3.7 Data Analysis Data were analysed with descriptive and inferential statistics using Statistical Package for Social Sciences (SPSS), version 22. Descriptive data were presented in tables by mean, standard deviation, and percentage where it was needed. 20 With the interviewed guide themes were developed through content analysis of data collected Transcripts were read several times by the team to identify codes. The team used similar code to create families and similar families grouped together as themes. Themes were discussed by all researchers to make sure they reflected the phenomenon that was captured during data collection. Some participants were also consulted to make sure the themes developed represented their views. 21 CHAPTER FOUR DATA PRESENTATION, ANALYSIS AND DISCUSSION OF RESULTS 4.0 Introduction In this section, the finding and outcomes found from both the interview and questionnaires are discussed. It reported the results of the investigation obtained from the respondents in the South Suntreso Hospital in Kumasi. The detailed discussion has been presented on the answers to each of the research question. The presentation was organized under the main headings: demographic information and analysis of the study's main data. 4.1 Demographic Information In order to carry out the analysis of the information gathered in order to reply the study questions, a quantitative review was carried out on the demographic characteristics of the examines in order to assist in the analysis, since these characteristics are considered to influence the results of the debate and the importance of the generalisation of the study findings. Three demographical of the respondent were inquired about i.e. age, gender and educational level. 4.1.1 Age: The ages of the respondent were group into four, from age 21 to 30, 31 to 40, 41 to 50 and 51 to 60, they recorded 17, 40, 30 and 8 respectively. The implies majority of the sampled respondents are between 31 to 40 years representing 42.11% followed by those in the group 41 to 51 which had 31.58%. The results is presented in Figure 4.1. 22 21-30 years 31-40 years 41-50 years 51-60 years 30 8 Age Series1 17 40 Figure 4.1: Age of Respondents Source: Author’s fieldwork 4.1.2 Gender Next to the age was gender, respondents were asked to indicate their sex and majority were females representing 57 which is 60% of the respondents and males were 38 which is 40% of the respondents as presented in figure 4.2. Meaning most of the people who are HAIs are females. Female Male Gender Series1 57 38 Figure 4.2: Gender of Respondents Source: Author’s fieldwork 23 4.1.3 Education Level The education level of the respondent were also asked, most of these patients had no formal education which represents 32 (33.68%) it was followed by those with only basic education which was also 26(27.37). the rest are those with high school education and tertiary recorded 21 representing 22.11 and tertiary was 11 (16.84%). Meaning majority of the respondent has no formal education. No Education Basic High School Tertiary Educational Level Series1 32 26 21 11 Figure 4.3: Education Level Source: Author’s fieldwork 4.2 Knowledge Level of Patient about Hospital Acquired Infection In other to test the knowledge level of patients about Hospital Acquired Infection six questions were asked, firstly, respondents were asked whether they have heard of HAIs 95 out of 115 representing 82.61% questioned “Yes” and 20 out of the 115 answered ‘No’ also representing 17.39%. Meaning majority of the patients have heard of HAIs. Therefore the study was carried out on the 95 (82.61%) of the respondents. The results is presented in table 4.1 Secondly, the 95 respondents were asked to define what HAIs is, among the population 78 representing (82.11) answered correctly and 17 which is 17.89 24 answered wrongly. Per the result is presented in table 4.1 it is clear majority of the respondent do understand the meaning of HAIs and had little knowledge of it. The respondents were again asked to indicate how the heard of HAIs, majority of the respondents which is 33(34.74) said they heard it from Health Officer, it was followed by respondents who have heard about it on the internet which is 27(28.42%), from radio or reading also recorded equal tilly of 14 representing 14.74%. television had the least which of 7(7.37). The outcome is presented in table 4.1. Table 4.2 Knowledge Level of Patient about Hospital Acquired Infection Statement Option Yes Have you heard of HAIs? If yes, what is HAIs? If yes, where did you hear it? Do you wash your hands within and after leaving the hospital? If yes, do you wash with soap? Do you believe the hospital is free from infections?

Most of the respondent answered ‘Always’ which was 44 (46.32%), sometimes and never had a frequency of 30 and 21 respectively as shown in Table 4.1. the results shows majority of the respondents have knowledge on how to prevent contacting HAIs. This is consistent with work done by Parmeggiani et al (2010), The respondent were again asked if they do wash their hands with soap, again majority which is 38 representing 40% indicated they do always , never and sometimes followed respectively with 31(27.37) and 26(27.37). This results is presented in table 4.1, and by the result it mean most people do wash their hands with soap after visiting the hospital. They respondents were also asked to indicate if they do believe the hospital is free from infections, majority which is 51 (53.68%) said ‘Yes’ and the rest of 44 which is 46.32 said ‘No’. the results is found in Table 4.1. 4.3 Causes of Hospital Acquired Infection The hospital is a large comprehensive hospital, in order to understand the characteristics of HAIs, inpatient hospital infection, to provide a reliable basis for the prevention and control of hospital infection, we use the hospital in two years in patients in the hospital patients hospital infection survey. By means of retrospective investigation, we observed the respondent of 95 patients with Hospital Acquired Infections collected from September, 2017 to December, 2019 in the hospital. The results showed that the nosocomial infection rate was 2.97% of the total admitted patients in the hospital. Monitoring of nosocomial pathogens: 200 cases of nosocomial infections occurred within the period of the study. The percentage in Table 4.2 shows that the main pathogens of nosocomial infections are G-Bacteria which is 47 representing 49.43%, G + Bacteria also recorded 23(24.21). Fungal 26 infections accounted for 27.35%, which was related to patients with low immunity, hormones, immunosuppressive agents and widespread use of anti-infective drugs. The study showed that the positive rate of nosocomial infection in at the hospital was low. Most of the HAIs was caused by G-Bacteria Table 4.2 Cause of HAIs Bacteria Tally % G-bacteria 47 49.47 Escherichia coli 7 7.37 Klebsiella pneumonia 3 3.16 Pseudomonas aeruginosa 15 15.79 Salmonella 4 4.21 Other Pseudomonas 10 10.53 Other G-bacteria 8 8.42 G+bacteria 23 24.21 Staphylococcus aureus 9 9.47 Streptococcus pneumonia 3 3.16 Staphylococcus epidermidis 3 3.16 Enterococcus 2 2.11 Other G + bacteria 6 6.32 Fungus 25 26.32 Total 95 100.00 Source: Author’s fieldwork, 2019 4.4 Preventive Measures of Hospital Acquired Infections Prevention of nosocomial infections requires an integrated, monitored, programme which includes the following key components: 1 Limiting transmission of organisms between patients in direct patient care through adequate hand washing and glove use, and appropriate aseptic practice, isolation strategies, sterilization and disinfection practices, and laundry 2 Controlling environmental risks for infection 27 3 Protecting patients with appropriate use of prophylactic antimicrobials, nutrition, and vaccinations 4 Limiting the risk of endogenous infections by minimizing invasive procedures, and promoting optimal antimicrobial use 5 Surveillance of infections, identifying and controlling outbreaks 6 Prevention of infection in staff members 7 Enhancing staff patient care practices, and continuing staff education. 8 Infection control is the responsibility of all health care professionals — doctors, nurses, therapists, pharmacists, engineers and others. Acquisition of nosocomial infection is determined by both patient factors, such as degree of immunocompromise, and interventions performed which increase risk. The level of patient care practice may differ for patient groups at different risk of acquisition of infection. A risk assessment will be helpful to categorize patients and plan infection control interventions. Tables 4.3 and 4.4 provide an example of an approach which could be customized to a particular facility. Table 4.3 stratifies the risk for different patient groups, and Table 4.4 provides a hierarchy of patient care practice for different levels of patient risk. Table 4.3. Differential nosocomial infection risk by patient and interventions Risk of infection Type of patients Type of procedures Minimal Not immunocompromised; no Non-invasive, No exposure to significant underlying disease biological fluids * Medium Infected patients, or patients with Exposure to biological fluids or some risk factors (age, neoplasm) Invasive non-surgical procedure (e.g. peripheral venous catheter, introduction of urinary catheter) High Severely immunocompromised patients, (<500 WBC per ml); multiple trauma, severe burns, organ transplant Source: WHO, 2002. 28 Surgery or High-risk invasive procedures (e.g. central venous catheter, endotracheal intubation) The importance of hands in the transmission of hospital infections has been well demonstrated and can be minimized with appropriate hand hygiene. Compliance with hand washing, however, is frequently suboptimal. This is due to a variety of reasons, including: lack of appropriate accessible equipment, high staff-to-patient ratios, allergies to hand washing products, insufficient knowledge of staff about risks and procedures, too long a duration recommended for washing, and the time required. Table 4.4 Aseptic measures appropriate for different levels of risk of infection Risk of Asepsis Antiseptics infection Hands Clothes Devices* Clean or disinfected at intermediate or low level Minimal Clean None Simple hand washing or hand disinfection by rubbing Street clothes Medium Asepsis Standard antiseptic products Hygienic hand washing or hand disinfection by rubbing Protection Disinfected against blood at sterile or and biological high level fluids, as appropriate High Surgical Specific asepsis major products Surgical hand washing or surgical hand disinfection by rubbing Surgical Disinfected clothes: dress, at sterile or mask, caps, high level sterile gloves Source: WHO, 2002. To minimize the transmission of microorganisms from equipment and the environment, adequate methods for cleaning, disinfecting and sterilizing must be in place. Written policies and procedures which are updated on a regular basis must be developed for each facility. Routine cleaning is necessary to ensure a hospital environment which is visibly clean, and free from dust and soil. Ninety per cent of microorganisms are present within “visible dirt”, and the purpose of routine cleaning is to eliminate this dirt. Neither soap nor detergents have 29 antimicrobial activity, and the cleaning process depends essentially on mechanical action. There must be policies specifying the frequency of cleaning and cleaning agents used for walls, floors, windows, beds, curtains, screens, fixtures, furniture, baths and toilets, and all reused medical devices. 30 CHAPTER FIVE SUMMARY OF FINDINGS, CONCLUSION AND RECOMMENDATIONS 5.0 Introduction This phase begins by summarising the key findings of the collected data. The chapter also provides conclusions and recommendations in line with the research objectives. It also highlights study limitations and finally provides proposals for future research studies. 5.1 Summary of Findings Knowledge of HAIs and compliance to methods in preventing them such as proper practice of aseptic precautions could lead to reductions in healthcare associated infections in the hospital. Results from the study indicated that majority 82.61% of HCWs have heard of HAIs, 78 (82.11%) understood what it was and had the requisite knowledge on how it can be prevented through hand. Comparatively, 82.61% of patients have heard of HAIs of which 78 (82.11%) understood what it was. Majority of patients who knew about HAIs had obtained information from health officers. Who noted that knowledge about hospital infection from trained HCWs such as nurses, doctors, and biomedical scientists was generally high and consistent with current scientific evidence. Considering the important safety and medico-legal implications for staff and patients, the HCW management practices in the hospital were good, with more participant having excellent practice and demonstrating good practice. The large number of respondent with good HAIs practice reported. The present survey shows that the most infectious sites are the respiratory system, which is consistent with domestic reports of nosocomial infections. The hospital is a large-scale comprehensive hospital. It treats more critically ill patients, and the 31 patients are more complicated, with low immune function, more invasive examinations and treatment operations, such as tracheal intubation and use of ventilator. Infectious drugs are prone to cause imbalance in flora and cause double infection. In addition, there are more advanced students and teaching students in the hospital, and the mobility of personnel is large, which is likely to cause cross infection among patients, medical care, visiting staff, and escorts, which are all important causes of respiratory infections. Therefore, strictly abide by the principles of aseptic technology, strict aseptic technique operation procedures and disinfection and isolation systems, strengthen the disinfection management of sputum suction, atomized inhalation, ventilator, oxygen humidification bottles, connecting pipes and other devices, and strictly prevent pathogens through management directly Enter the patient's airways; minimize procedures. Investigation showed that the positive rate of nosocomial infection in our hospital was low. Therefore, strengthen the management of nosocomial infections, increase the awareness of clinicians, attach importance to the cultivation and drug sensitivity of pathogenic bacteria, avoid the blindness and irrationality of drug use based on experience, and promptly send samples for which anti-infective drugs have not been applied in order to increase the positiveness of the samples submitted. The detection rate and accuracy rate provide a reliable basis for the rational use of anti-infective drugs in the hospital. It is very important to strictly grasp the indications for the use of anti-infective drugs, timely and accurately understand the dynamics of pathogenic bacteria and the changes of drug-resistant strains, and to regulate the use of antiinfective drugs reasonably. Extending the length of hospital stay, causing unnecessary suffering to patients, and correspondingly increasing medical expenses, increasing the burden on patients, and even causing medical disputes. Therefore, we must strengthen nosocomial infection management, carry out nosocomial infection 32 training, improve medical staff's awareness of nosocomial infections, and implement effective preventive measures to reduce nosocomial infections. Without additional infection control measures, an increased rate of nosocomial infection can be expected in these patients. Therefore, prevention of nosocomial infections remains of the utmost importance. In addition, as the prevention of nosocomial infection improved with chlorhexidine gluconate, a shorter mean hospital stay was observed. 5.2 Conclusion In conclusion, majority of HCWs have knowledge and understanding of HAIs' preventive methods However, implementation of these knowledge through compliance of preventive methods must be encourage among patients More than half of patients have some information on HAIs having been informed by a health officer, 46.32% with always washing their hands and 31.58% washing always with soap. Majority believe the hospital is free from infection with 44.8% believing they had had HAIs. Thus in patients, increased information on HAIs will lead to a reduction whereas in HCWs strict adherence and monitoring of compliance to hospital regulations on HAIs will instil the desired attitudinal change that will result in reduction in HAIs. The high risk factors of hospital acquired infections are immunosuppression, more invasive examinations and treatments and long-term using antibiotics. Therefore, we must strengthen nosocomial infection management, carry out nosocomial infection training, improve medical staff's awareness of nosocomial infections, and implement effective preventive measures to reduce nosocomial infections. It is the responsibility of all health care providers to enact principles of care to prevent health care–associated infections, though not all infections can be prevented. Certain patient risk factors such as advanced age, underlying disease and severity of illness, 33 and sometimes the immune status are not modifiable and directly contribute to a patient’s risk of infection. Depending on the patient’s susceptibility, a patient can develop an infection due to the emergence of their own endogenous organisms or by cross-contamination in the health care setting. Benefits of antimicrobial therapy will alter the microbial flora by reducing one microbial presence but may allow the emergence of another, causing a new infection (e.g., antibiotic-associated diarrhea). Nurses can reduce the risk for infection and colonization using evidence-based aseptic work practices that diminish the entry of endogenous or exogenous organisms via invasive medical devices. Proper use of personal protective barriers and proper hand hygiene is paramount to reducing the risk of exogenous transmission to a susceptible patient. For example, microorganisms have been found in the environment surrounding a patient and on portable medical equipment used in the room. Environmental surfaces around a patient infected or colonized with a multidrug-resistant organism can also become contaminated. Health care workers should be aware that they can pick up environmental contamination of microorganisms on hands or gloves, even without performing direct patient care. Proper use and removal of PPE followed by hand hygiene will reduce the transient microbial load that can be transmitted to self or to others. Identified aseptic and infection control practices have been proven to reduce the dissemination of organisms to a single patient, to prevent repeated transmissions that contribute to an outbreak situation among multiple patients, or to become established in the health care environment as endemic hospital flora. It has been demonstrated that nursing and medical practices can pick up transient microorganisms from intact patient skin and from environmental surfaces. Although the amount of contamination is not quantified and the exact incidence is not apparent, 34 it does occur. Hand hygiene and aseptic practices before caring for a susceptible patient can reduce the transient carriage and transfer of microorganisms. The protective benefits of infection control using evidence-based practices are cost effective and numerous: they not only contribute to the best individual patient care outcome, but also protect health care workers, increase public awareness in all health care settings about infection control issues, and maintain the highest standards in nursing, which positively contributes to our goal for the best possible patient and public health outcomes. 5.3 Recommendation Basing on the finding of this survey, the following recommendations were made 1 Radio interviews should be done on HAIs so to increase the knowledge level of the general public. 2 Gloves Sterile gloves should be worn after hand hygiene procedure while touching mucous membrane and non-intact skin and performing sterile procedures e.g. arterial, central line and Foley catheter insertion 3 Gown Wear a gown to prevent soiling of clothing and skin during procedures that are likely to generate splashes of blood, body fluids, secretions or excretions. The sterile gown is required only for aseptic procedures and for the rest, a clean, nonsterile gown is sufficient (2A). Remove the soiled gown as soon as possible, with care to avoid contamination. 4 Mask, eye protection/face shield Wear a mask and adequate eye protection (eyeglasses are not enough), or a face shield to protect mucous membranes of the eyes, nose and mouth during procedures and patient care activities that are likely to generate splashes/sprays of blood and body fluids, etc. 5 Patients, relatives and health care workers (HCWs) presenting with respiratory symptoms should also use masks (e.g. cough). 35 REFERENCES Allegranzi, B. and Pittet, D., 2009.
