The nosocomial infection is some of the infection that occurs in the hospital.
According to Ochie, et al. (2009) and Lim, et al. (2008) nosocomial infection is the infection
that occurs after 48 hours patient admit to the hospital. The nosocomial infection also can
be describe as the disease that patient have after 30 days patients discharge from hospital.
Patient that having nosocomial infection can be category as the patient that has disease that
he or she not has before admitted to the hospital. The term nosocomial infection can be
describes as hospital acquired infection, (Fox, et al., 2008). Futhermore, when the infection
had been infected by healthcare workers the term change to occupationally acquired.
(Ehrlich, et al., 2009).
Based on Horan, et al. (2008) the infection can be categories as urinary tract infection
(UTI), surgical site infection, bloodstream infection, pneumonia, gastrointestinal (GI) system
infection, lower respiratory tract infection that are other than pneumonia, reproductive tract
infection, skin and soft tissue infection, bone and joint infection central nervous infection,
cardiovascular system infection and systemic infection. According to Ochie, et al. (2009) the
most common infection is UTI.
Radiology department may have a role to diagnosis the patient. For that, the
radiology department receive a lot of patients whether outpatient or in patient. (Ochie, et
al., 2009 and Tugwell, et al., 2011). We can conclude that radiology department have high
risk to spread the diseases from patient to staff, staff to staff, patient to patient, equipment
to patient and staff and vice versa.
According Ochie, et al. (2009) some of the equipment that can contribute to spread
the disease or pathogens are x-ray couches, chest stands, control panel, exposure buttons,
cassette that has been used while mobile radiography and patient gowns. Based on Fox, et
al. (2008) cassette x-ray is the possible equipment that can be source of the nosocomial
infection. However Ochie, et al. (2009) were found a lot of common bacteria in the cassette
that has been used while performing mobile radiography. Bacteria that have been found
were Coagulase negative staphylococcus, micrococci, diphtheriods and some of the species
of bacillus. As we know, cassette is the equipment that always direct contact with patient
skin, so from that we can conclude that cassette is one of the most equipment that can be
the source of nosocomial.
Ochie, et al. (2009) they were found a lot of bacteria such as staphylococcus aureus,
pseudomonas aeruginosa, klebsiellaspp , enterococcus spp, citrobacterspp, acinobacterspp,
yersinaenterolitica, treponema palladium, mycobacterium tuberculosis, coagulase-negative
staphylococci (epidermidis and saprophyticus) and coliform spp. Klebsiellaspp is the most
bacteria found in radiographers’ hand. Furthermore, coliform spp can be related to medical
staff’s hands and also can be associated with equipment. In this journal also, they stated that
bacteria can enter by open route and wound. So, all medical staff and patient should be
aware about this.
Based on Fox, et al. (2008) nosocomial infection has been investigated while doing
mobile radiography. Some of the bacteria have been found were Escherichia coli,
Enterococcus faecalisand Staphylococcus aureus. Bacteria can grow inanimate things such as
x-ray cassette. In this study also said that, there were no approve that cassette can cause
nosocomial infection but cassette was the things that pathogen grow, so it can contribute to
nosocomial infection.
While we are focusing only to x-ray cassette, x-ray couch and all big equipment, we
are forget about small object like radiographic marker. All radiographers have their own
radiographic marker but in the study by Tugwell, et al. (2011) said that rare of the
radiographers wash or clean their radiographic marker. Radiographic marker has been used
in all examination. All the bacteria will be transmitting to radiographer hand and
radiographer will be contact with patient. It will decrease the effectiveness of performing
hand hygiene and then it will be increasing the nosocomial infection.
Study has been done by Okaro, et al. (2010) reported that body fluid also can be one
of the factors of nososcomial infection if radiographer not aware about this infection. Okaro,
et al. (2010) also reported that recapping needle after using it was very command. So, if that
procedure is apply in all time, maybe some of radiographer will injured by that needle. It was
very dangerous because open wound is one of the routes of nosocomial infection. It will
increase infection among radiographers.
In this research reported that only 41.7% of radiographers apply the principle of
universal precaution. It is not achieve half of the practitioner, so we have to worry with this
situation Most of radiographers only clean their equipments such as cassette and couch
after treat patients with open wounds. In this research also reported that most of
radiographers also only clean their hands after treat the some conditions of the patients.
(Okaro, et al., 2010).
Research conducted by Tan, el al. (2005) was focusing in patient having tuberculosis
(TB). TB can be spread if health workers not alert about infection control. Some of
radiographers not wearing the mask while examine patient with this condition. It can infect
to radiographers and it will transmit to other patient if the radiographer not aware. It is
because to confirm that the patient have TB, that patient have to come to check their chest,
so from that we know that radiographer is the high tendency to get TB and spread to other
patient if they not aware about nosocomial infection.
There are a lot of effects if health workers not alert about infection control. Fox, et al.
(2008) found that more than 100000 people get nosocomial infection. The London School of
Hygiene Survey reported those patients that have nosocomial infection admitted to the
hospital 11 days longer. It will cause the cost of treatment increases. (Fox, et al., 2008).
Some of the reasons why they do not perform precaution procedure is they do not
have enough education. In journal reported by Saleh, et al. (2009) study in Egypt has been
done ad they found 24022 health care workers get infection hepatitis C virus (HCV) and 8617
hepatitis B virus (HBV). However, this studies only done within nurses, laboratory technician
and housekeeper. Most of them received one time education about precaution education.
We can conclude that they receive less education. One time education is not very necessary.
In this study, the health education intervention is effective. Level of knowledge in laboratory
technician is higher than nurses but the practice is lower than the nurses. (Saleh, et al.,
Others reasons reported by Saleh, et al. (2009) they were lack of the equipment to
prevent nosocomial infection such as gloves and safety boxes needle disposal, work overload
and lacking of training to perform precaution procedures. Okaro, et al. (2010) also agreed
that not only knowledge can prevent the nosocomial infection but the training and adequate
skill of radiographer to prevent nosocomial infection was also the important things. They
also said the reason why radiographer to having adequate skill was radiographer has high
tendencies to spread the pathogen that can cause nosocomial infection.
To prevent nosocomial infection to be spread out, there are some precautions that
radiographers have to follow. In journal reported by Onifade, et al. (2007) 20, they were
focused on sharp policy that has been used at Lagos University Teaching Hospital, Nigeria.
They said that policy was to prevent transmission of pathogen among patient and health
workers. This studies also said that the level of knowledge of ‘sharps’ among patient and
health workers were high but the knowledge about sharp policy was not very good. The
sharp policy was important to know because it can reduce sharp injuries. Furthermore, it will
reduce the nosocomial infection because sharp injuries can be the factor of nosocomial
Other than that, they were focused on hand washing technique. The most effective
method to prevent nosocomial infection was performing right hand washing technique.
(Patakarul, et al., 2008). They also said that hand washing was very crucial and less expensive
to be done among patient, health workers and visitor. Based on research were done by
Patakarul, et al. (2008) and Gould, et al. (2008) their studies were focused at intensive care
unit (ICU) and cardiac care unit (CCU). Patakarul, et al. (2008) reported that, none of the
radiographer performing hand washing technique while doing examination on patient at ICU
and CCU. In their studies also they were included visitor as the subject because visitor also
can be source of nososcomial infection. Performing of hand hygiene was low among the
visitor. (Patakarul, et al., 2008).
Furthermore, to prevent nosocomial infection was using alcohol hand rub. This
method was very easy and less time needed to perform it. (Patakarul, et al., 2008). After
performing alcohol hand rub, they are not recommended to perform hand washing
technique because it can cause dermatitis. In their studies, they also include the reasons why
health workers, patient and visitor not performing hand hygiene. The reasons were they
were forgetful and lacking of knowledge.
To clean equipment, Ochie, et al. (2009) were suggests to use some chemical
disinfectant agents such as chloroxylenol, dichloroxyleenol, sodium hypochlorite and
methylated spirit. The most effective chemical disinfectant agent was sodium hypochlorite.
But some of the practitioner, they were just using water to clean the equipments and hands.

Study Design
Prospective study.
Study Location
This project will be done mainly at Hospital Tuanku Jaafar Seremban, Negeri Sembilan.
Sample Size
For this study, at least 30 radiographers will be selected. The inclusion criteria for this study
is radiographers that perform mobile radiography. Otherwise, the exclusion criteria are
radiographers that not perform mobile radiography. Age and working experience in this
study not included.
Data Collection
The data will be collected using questionnaire. This questionnaire has four (4) parts. Part A
will be personal information. Part B will be questions for assessing stage of awareness and
for part C will be assessing practice of radiographer toward nosocomial infection during
mobile radiography. The last part will be assessing the method had been used by
radiographers to prevent nosocomial infection. The data that has been collected will be
transfer in Microsoft Excel and will be calculate and analyse using SPSS 14.0 for windows. For
awareness, practice and method that radiographers used, frequencies with means and
standard deviation will be computed. For the correlation of awareness and attitude, I will
use T-test.
