  1. Exposure to Infectious Agents in Health Protection Agency Laboratories Presented by Frances Knight and Ian Bateman

  2. HEALTH PROTECTION AGENCY • formed April 2003 • CMO – Getting ahead of the curve • formed from PHLS, CAMR, National Focus • joined in 2004 by NRPB • around 3000 staff • 3 major centres, 79 sites • 1500 staff work in microbiology

  3. BACKGROUND • Diphtheria infection in member of staff • HPA Board requested review • Investigate laboratory exposures to infectious agents • Review adequacy of actions to prevent infections in staff • Recommend improvements • Identify issues of wider relevance

  4. TERMS OF REFERENCE • examine laboratory acquired infections and incidents of exposure to infectious agents during laboratory work • identify number of incidents over 2 years and the circumstances in which they arose • review immediate and underlying causes • review lessons learned • review actions taken and whether they were adequate • determine further steps to ensure this area of risk is adequately controlled • final report for the HPA Board • make recommendations for further action

  5. FINDINGS (1) • 78 recorded incidents • Hazard Group 1 (1) • Hazard Group 2 (40) • Hazard Group 3 (32) • Hazard Group 4 (2) • Not known (3) • 6 LAIs (Salmonella Typhimurium, Shigella sonnei (2 cases), • Corynebacterium diphtheriae, Salmonella Agona and Neisseria • meningitidis ) • Full recovery, no transmission to others

  6. FINDINGS (2) • 70% - SPILLS, BREAKAGES AND LEAKS • 13% - SHARPS • 11% - NO MSC/GENERATION OF AEROSOLS

  7. REVIEW OF SPECIFIC INCIDENTS • LAI – Corynebacterium diphtheriae • LAI – Salmonella Agona • Mycobacterium tuberculosis – dropped culture • Mycobacterium tuberculosis – dropped swab • LAI - Neisseria meningitidis

  8. UNDERLYING CAUSES • staffing levels • off-site training • competence • communication • immunisation status • accommodation pressures

  9. ACTION PLAN (1) • Increased vigilance and awareness • keep biological safety high on the agenda • Communicate findings via cascade • targeting key groups • Improved risk assessment • especially resource/space • Standard arrangements • incident reporting, investigation & analysis • System for communicating lessons learned • including pan-HPA communication of HSE visit findings • Better and more consistent CL3 training

  10. ACTION PLAN (2) • review practices against HSAC, ACDP, etc • processing at wrong containment levels • create environment for open reporting • frequency of CL2 and CL3 incidents • monitor progress against action plans • share findings across microbiology + HSE
