SUMMARY Isolation systems are designed to contain the spread of infection The principal objective is to contain the harmful organism and not the infected person. Isolation precautions can be applied to a patient on a multi - bedded ward, a cohort of patients suspected to have the same pathogen, or to a patient in a single room. Single rooms on a ward are the mainstay of isolation in the Trust. Open ward areas can be effective in controlling the spread of infections transferred by contact as long as appropriate precautions are still implemented, The University Hospital has an Infectious Diseases Unit situated on ward A7 that will accept adult patients requiring isolation. Negative pressure rooms are not required for most organisms but find particular value when dealing with highly infectious airborne agents. Certain diseases (or suspicion of) are notifiable by law to the Public Health Department (Bro Taf) - Consultant in Communicable Disease Control (CCDC). The clinician who considers or diagnoses the infection is responsible for the notification. The Trust IPCD should also be informed of these diseases. Three levels of precautions/ isolation observed in the Trust are: i. Contact Precautions/Isolation used in situations where the mode of transfer of the infecting organism is via blood-to-blood contact (e.g. hepatitis), the faecal oral route (e.g. viral gastroenteritis and other enteric pathogens) or by contact. ii. Respiratory Isolation used to prevent the transmission of infectious diseases over short distances through the air. Serious infections spread by the respiratory route should preferably be placed in negative pressure rooms. iii. Strict Isolation used for the isolation of highly communicable diseases. Appropriate isolation cards should be displayed on the outside of the door of the isolation room. Handwashing before and after contact with any patient is the single most important measure in preventing the spread of infection. isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 6 2. GUIDANCE NOTES FOR THIS DOCUMENT Do not hesitate to contact the Infection Prevention and Control Department (IPCD) if any advice or clarification is needed with regard to isolation procedures or any other infection prevention and control issues. It is essential that patients isolated in a single room or in a co-hort on wards do not feel ostracized in any way. The reasons for isolation should be clearly explained to the patient and close family members. An information leaflet explaining issues regarding isolation is available. It is the responsibility of the Ward Manager (or Nurse-in-Charge of the ward) to ensure that all members of staff adhere to this policy, and that the patient and their relatives are properly advised about isolation procedures. Members of the Infection Prevention and Control Team (IPCT) are available to talk to patients and relatives if required. Some diseases are notifiable by law (see section 5); it is the responsibility of the clinician who considers the diagnosis of any of these infections to notify the Consultant in Communicable Disease Control (CCDC). It is essential that all notes are appropriately flagged, if necessary, and that General Practitioners, other Health Care and relevant social agencies are informed of the patient's status on discharge. If additional advice is required they can contact the IPCD or the CCDC’s office. In the event of a patient being suspected of having a Viral Haemorrhagic Fever in either the Emergency Unit (UHW), Emergency Assessment (Llandough) or at ward level, do not move the patient, limit the number of staff that come into contact with the patient and then immediately contact one of the following: Trust Consultant in Infectious Diseases or deputy - via UHW switchboard Trust Consultant in Infection Prevention and Control/Department Health Authority Consultant in Communicable Disease Control - 20 402478 Out-of-hours On-call Microbiologist or Virologist - via UHW/Llandough switchboard. Immediate advice will be available from one of the above at any time of day or night. isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 7 3. INTRODUCTION The Infection Prevention and Control Department produces guidelines, which aim to:a. decrease the occurrence of infection b. contain spread if infection should occur Isolation systems are designed to address item (b), the principal objective being to contain the harmful organism and not the person. Isolation precautions can be applied to a patient on a multi - bedded ward, a co-hort of patients suspected to have the same pathogen, or to a patient in a single room. Which system is ultimately employed depends on the patient, the pathogen and resources for isolation. isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 8 4. ISOLATION FACILITIES 4.1 SINGLE ROOM OF A GENERAL WARD These facilities are the mainstay of isolation in the Trust. Their value depends on strict compliance with the code of practice for the type of isolation under consideration and the extent to which the room is self-contained. 4.2 MAIN WARD AREAS Open ward areas can be effective in controlling the spread of infections transferred by contact as long as appropriate precautions are still implemented, i.e. the same techniques that would be used if the patient was in a single room e.g. strict handwashing, gloves, aprons as required. If an open ward area has to be used then the quietest area, or one near a handwashing basin, should be chosen. The co-horting of infected patients may be used in some circumstances under the direction of the IPCD. 4.3 INFECTIOUS DISEASES UNIT - UHW The University Hospital has an Infectious Diseases Unit situated on ward A7 that will accept patients that require isolation. There are four negative pressure isolation rooms, which are completely self-contained, and two single cubicles as found on other wards. Negative pressure rooms are not required for most organisms but find particular value when dealing with highly infectious airborne agents e.g. patients with open pulmonary tuberculosis or chicken pox. isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 9 5. NOTIFIABLE DISEASES The following diseases (or suspicion of) are notifiable by law to the Public Health Department (Bro Taf) - Consultant in Communicable Disease Control (CCDC); the clinician who considers or diagnoses the infection is responsible for the notification. Persistent carriers of typhoid bacilli and other Salmonellae should also be reported. For optimal in-hospital infection prevention and control the on site IPCD staff should also be notified. LIST OF NOTIFIABLE DISEASES (July 1998) Acute encephalitis - bacterial and viral Acute poliomyelitis Anthrax Cholera Diphtheria Dysentery - amoebic or bacillary Food Poisoning (or suspected food poisoning) Leprosy Leptospirosis Malaria Measles Meningitis - bacterial and viral Meningococcal septicaemia Mumps Ophthalmia neonatorum Paratyphoid Fever Plague Poliomyelitis: acute Rabies Relapsing Fever Rubella Scarlet Fever Smallpox Tetanus Tuberculosis - pulmonary and non-pulmonary Typhoid fever Typhus Viral Haemorrhagic Fevers Viral Hepatitis Whooping Cough Yellow Fever isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 10 Notification should be made by telephone in the first instance followed by notification on the official form to: The Consultant in Communicable Disease Control Temple of Peace and Health Cathays Park Cardiff Tel: 029 20 402478 Notification by phone only should also be made to the IPCD. The IPCD should also be informed of any diseases/pathogens not listed here which present a risk of hospital acquired infection e.g. M.R.S.A., Group A Streptococcus in a wound. isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 11 6. CATEGORIES OF PRECAUTIONS AND ISOLATION The different levels of precautions and isolation required to prevent the spread of infective organisms are detailed below. It is essential that all members of staff observe these guidelines. The levels of precautions/ isolation observed in the Trust are: Contact Precautions/Isolation Respiratory Isolation Strict Isolation 6.1 CONTACT PRECAUTIONS/ISOLATION Contact precautions/isolation are used in situations where the mode of transfer of the infecting organism is via blood-to-blood contact (e.g. hepatitis), the faecal-oral route (e.g. viral gastroenteritis and other enteric pathogens) or by contact, usually via the hands, skin, mucous membranes or wounds (e.g. MRSA, VRE). A single room is preferred, but not always required for this level of precautions. For example, patients with infections that are spread by blood to blood contact a single room is preferred, but not essential, unless they are bleeding, if a patient has diarrhoea, a single room is preferred, if a patient is colonised with MRSA on the skin, a single room is preferred but not essential. If MRSA is found in discharging wounds or patient has respiratory tract colonisation then the risk assessment would require that a single room is used whenever possible. Open ward areas can be effective in controlling the spread of infection as long as the same precautions are used if the patients were in a single room. A single room with its own toilet is preferable but if this is not feasible then a dedicated commode should be used. Cohorting may be considered for patients who have the same pathogen. If a single room is used: Visitors and members of staff from other departments must report to the Nursein-Charge before entering the room. isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 12 The door of the room should be kept closed at all times unless the clinical need of the patient dictates otherwise. A contact isolation sign (orange) should be displayed on the door. Patients should not leave the room/ward area to attend other departments without prior arrangement/notification of the receiving department. Gloves should be worn if there is any risk from contamination with blood and body fluids. Plastic aprons must be worn when soiling is likely. Masks are not required unless there is the additional risk of airborne spread e.g. vomiting during episodes of viral gastroenteritis. Full face protection e.g. visor or goggles, must be worn if there is a risk of splashing from blood or body fluids and secretions Hands must be washed with soap and water and then disinfected with an approved hand disinfectant (e.g. alcohol gel) before entering the room, after patient contact, after contact with potentially infected materials, and after removal of disposable gloves. 6.2 RESPIRATORY ISOLATION e.g. tuberculosis, chickenpox Respiratory isolation is used to prevent the transmission of infectious diseases over short distances through the air. Serious infections spread by the respiratory route should preferably be placed in negative pressure rooms. Transfer/admission to the Infectious Diseases Unit (A7, UHW) should be considered in these cases. A single room should be used; if one is not available contact the IPCD. Visitors and members of staff from other departments must report to the Nursein-Charge before entering the room. Patients should not leave the room to attend other departments without prior arrangements. A respiratory isolation sign (pink) should be displayed on the door. The door of the room should be kept closed at all times unless the clinical need of the patient dictates otherwise. isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 13 Gloves should be worn if there is any risk from contamination with blood or body fluids. Plastic aprons must be worn when soiling is likely. Masks should be worn by those who come into close contact with the patient. Specialist masks for tuberculosis should be used for contact with cases with open pulmonary TB. Full face protection e.g. visor or goggles should be worn if there is a risk of splashing from blood or body fluids and secretions Hands must be washed with soap and water and then disinfected with an approved hand disinfectant (e.g. alcohol gel) before entering the room, after patient contact, after contact with potentially infected materials, and after removal of disposable gloves. 6.3 STRICT ISOLATION e.g. suspected diphtheria, suspected viral haemorrhagic fever. IMMEDIATELY NOTIFY THE CCDC ON FIRST SUSPICION OF A DIAGNOSIS (Tel: 029 20 402478) AND THE INFECTION PREVENTION AND CONTROL DEPARTMENT. The hospitals in the Trust are not equipped for the admission of some diseases e.g. viral haemorrhagic fevers. If admission is agreed the patient must be admitted to one of the negative pressure rooms on the Infectious Diseases Unit immediately. Visitors and members of staff must report to the Nurse-in-Charge before entering the room. Patients must not leave the room without permission from a consultant in either Infection Prevention and Control or Infectious Diseases. A strict isolation sign (red) must be displayed on the door. The door of the room must be kept closed at all times. Gloves must be worn by all persons entering the room. Impervious gowns and impervious aprons must be worn by all persons entering the room. Masks must be worn by all persons entering the room. isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 14 Hands must be washed with soap and water and then disinfected with an approved hand disinfectant (e.g. alcohol gel) before entering the room, after patient contact, after contact with potentially infected materials, and after removal of disposable gloves. Flag all specimens to the laboratories as "high risk". isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 15 7. MATERIALS REQUIRED FOR ISOLATION 7.1 INSIDE PATIENT'S ROOM In addition to the standard equipment in an isolation room the following dedicated equipment should be provided Stethoscope Sphygmomanometer Thermometer 7.2 OUTSIDE PATIENT'S ROOM (or entrance to isolation ward area) Isolation card Disposable gloves Alcohol gel Disposable plastic aprons Masks (if required) Patients notes 7.3 ISOLATION CARDS An appropriate isolation card should be displayed on the outside of the door of the isolation room. The following isolation cards should be used: Contact precautions/isolation Respiratory isolation Strict isolation 7.4 Orange Pink Red (available on IDU and IPCD only) HAND-WASHING Handwashing before and after contact with the patient is the single most important measure in preventing the spread of infection. It should be noted that the hands should be wet before the application of soap to prevent dermatitis. Alcohol gel for hand decontamination should be available both in the room and outside the isolation room. Hands should be dried thoroughly. Hands must also be washed after the removal of gloves. isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 16 7.5 LAUNDRY Linen should be disposed of at the point of use. Used linen should be put into an alginate bag (water soluble), which should then be placed into a red laundry bag (linen skip) and taken to the appropriate pick up point. 7.6 WASTE Clinical waste should be placed into a yellow clinical waste bag. A bin should be provided both inside and outside the room. The bag should be sealed and labelled in the room in accordance with the Trust Waste Management Policy, before removal to the pick up point. 7.7 PATIENT CHARTS Patient’s charts/notes should be kept outside of the isolation room/area. 7.8 CUTLERY AND CROCKERY The use of disposable cutlery or crockery is not required. isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 17 8. CLEANING OF ROOMS 8.1 DAILY Wash all horizontal surfaces with warm water and detergent, and when dry, clean with an appropriate disinfectant and then allow to dry. (see Decontamination Policy, 2002). 8.2 TERMINAL Wash surfaces including the bed, bed frame and floor with warm water and detergent, and when dry, clean with an appropriate disinfectant and then allow to dry thoroughly before admission of another patient. Details of the disinfection of individual pieces of equipment, and the choice of appropriate disinfectant can be found in the Cardiff and Vale NHS Trust Decontamination Policy (2002). isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 18 9. TRANSFER OF INFECTED PATIENTS As with other Infection Prevention and Control matters, the designated Nurse-in-Charge of the ward has the responsibility to ensure that the necessary information regarding an infected/colonised patient is passed on to a senior member of staff of the receiving ward/department/hospital, prior to transfer. 9.1 WITHIN THE HOSPITAL Transfers to other wards should be avoided if at all possible, with the exception of the Infectious Diseases Unit if required. If transfer has to be effected then the receiving ward should be informed of the current status of the patient. 9.2 VISITS TO OTHER DEPARTMENTS (INCLUDING THEATRES) Visits to other departments should be kept to a minimum. When this is needed, prior arrangements should be made with the senior staff of the department concerned. Infected patients should in general be treated at the end of the working session and should spend the minimum time in the department. They should only be sent for when the receiving department is ready and not left in a waiting area with other patients. These guidelines should never jeopardise clinical need. 9.3 AMBULANCE TRANSPORTATION The ambulance service should be notified prior to transfer. Further information for the ambulance service should be obtained from the Consultant in Communicable Disease Control of the Health Authority (029 20 402478). 9.4 TRANSFER TO OTHER HOSPITALS Inter-hospital movements should be kept to a minimum. It is the responsibility of the transferring ward to inform the receiving hospital of the current status of the patient. If an infection control problem exists or has recently existed on a given ward it is worthwhile informing a receiving hospital of this even if the patient being transferred is not affected. 9.5 DISCHARGE OF PATIENTS The General Practitioner, other Health Care and relevant social agencies involved in the patient's care should be informed and advised of any decontamination procedures being undertaken as necessary e.g. MRSA decolonisation. isolation policy 2001/I:winword.policies.isolation.isolat00.doc/06.01/ipcd.dwh.lj.sc/adopted.06.01/review.06.03 19 10.
