precaution and infection control measures

Structural problem
1. PWH is not an infection disease hospital. The isolation and supporting facility are not appropriate nor adequate.
Unexpected / rapid accumulation of a large number of patients
2. Unexpectedness of the outbreak. No preparation for the outbreak.3. The tremendous caseload (70 HCW over a few days only)4. Necessary to draft in temporary nursing staff from other ward / dept5. Viral load on the ward was likely to be very high.
OUTBREAK OF SECONDARY INFECTION OF SARSAMONGST HEALTH CARE WORKERS AT PWH
– REVIEW AND RECOMMENDATION
Staff issues
6. Most of the staff did not attended structured briefing on management of SARS case before commencement of duty (too
busy)
7. Problem with using the N95 mask – correct size, too stuffy, not tolerate continuous use, rubbing of nose,
etc.
8. Compliance all the infection prevention measure - hand washing is not routinely performed - wrong order in self-decontamination on leaving the infection ward- performing high risk procedure without full protection
9. Long exposure time of the nursing staff to the infected patients
10. Social contact with “infected” colleague with early (mild) symptoms such as tea break, dinning together, sharing room
tea break was held in the pantry within the infected ward area
11. Short posting of staff into infected area -HCW drafted into an infection ward for 1 day
Patient issues
12. Patient not wearing mask.
13. Possible contamination by patient (saliva, food, etc) during feeding, medication round, etc.
ACTION PLAN:
1. To establish an “Infection risk and safety” concept and culture across NTEC
- commenced Saturday 29th March 2002 across NTEC
2. Re-classification of level of “risk” of the wards and to ensure appropriate barrier protective apparel
for all staffs, patients and visiting relatives (i) Ultra-high risk wards
(ii) High risk wards
(iii) Moderate risk wards
3. Structured briefing and training on caring for patients with SARS
- compulsory for staff going to work in the infection wards.
4. Staff protection(i) Appropriate barrier protective apparel
(ii) Ensure the mask (N95) fit well for ultra high risk staff(iii) Proper barrier protective process [入門七事 , 出門七事 ]
(iv) Enforce hand washing / disinfection
5. Staff compliance(i) Safety controller (SC) to be on duty on each shift
(ii) SC to undergo proper instruction course (iii) Remind all the staff of the IC measure before each shift.
6. Patient compliance (i) Ensure all patients wear mask all the time (ii) prohibit patient touching the case note, x-ray etc
7. Use of Nebuliser Prohibited
8. Management issues / contingency plan
(i) Establish rapid surveillance system (a) surveillance team to closely monitor any outbreak (b) rapid analysis of the reason for the outbreak
(ii) Establish rapid response plan for outbreak of infection Be prepared for sudden major outbreak
(i) designated stand-by ward (preferably with isolation facility)(ii) identify trained standby staff (doctor, nurse, AH, HCA) (iii) protective apparels to be made available immediately.(iv) defined action plan (v) establish control centre

Role of Unit ICOTo coordinate the IC programs at ward / unit / office level
(1) To conduct environmental risk scanning (for cross-infection)
(2) To verify the risk level (stratification) with the DICOif necessary, to add additional specific IC guideline for the unit
(3) To ensure the appropriate IC program - ensure the IC program is implemented on the department / ward level
- appoint shift ICO- ensure all staff have attended briefing on prevention of SARS
- ensure there is briefing on IC control for every shift

PROBLEMS / ISSUES (1):
(1) ENVIRONMENTAL - ward layout, airflow, bedpan washer, etc
(2) PATIENT- Atypical presentation (especially elderly patient)
- Multiple diagnosis / infection> Need high level of awareness / suspicion
Unsuspected AP admitted or developed on the ward
> reorganize the ward / cohort patients with fever Triage / isolation system
(a)confirmed AP / SARS ward(b) suspected SARS ward
(c) infection triage / fever ward(d) Other ward
Problems / issues (2)
(3) CARING OF PATIENT Elderly patient, need nursing care, close contact ++, Handling of excreta, contact with saliva, vomitus
High risk procedures> Strict IC prevention measures
(4) CROSS INFECTION patient-staff, staff-staff, staff-patient, patient-patient
(staff continue to work with symptoms)> Strict IC measures on the ward
> take immediate sick leave when develop symptom (fever)
(5) Staff issues- Adequate training / preparation
- Adequate & appropriate protection (PPE)
