learning objectives
Learning Objectives

By the end of the unit, participants should be able :

  • Define Laboratory Acquired Infections and describe how they are acquired
  • Understand how Biorisk Management can be used to define practices to prevent LAIs
  • Examine your laboratory/facilities for gaps in protecting against LAIs
what are lais
What are LAIs?
  • Definition
    • All infections acquired through laboratory or laboratory-related activities regardless whether they are symptomatic or asymptomatic in nature.
  • Examples?

how are they acquired
How are they acquired?
  • Inhalation (aerosols)
  • Percutaneous inoculation (needle and syringe, cuts or abrasions from contaminated items, and animal bites)
  • Contact between mucous membranes and contaminated material (hands or surfaces)
  • Ingestion (aspiration through a pipette, smoking or eating)

class exercise protecting against lais
Class Exercise: Protecting Against LAIs
  • In your groups, discuss how you prevent LAIs
    • Please write your answers on ‘post it’ note and place on your flip chart.
    • Report to the class
  • Now group these methods into categories:
    • Please write your answers on ‘post it’ note and place the on your flip chart.
    • Report to the class
hierarchy of controls hoc
Hierarchy of Controls (HOC)
  • Elimination or Substitution
  • Engineering Controls
  • Administrative Controls
  • Practices and Procedures
  • Personal Protective Equipment

Control methods at the top of the list are in general more effective and protective than those at the bottom.

cataract university example
Cataract University Example
  • Individually, carefully read the Cataract University exercise
  • Divide into groups
    • Identify problems with Biorisk Management. These problems could be associated with assessment, mitigation or performance
    • Use post-it notes, one for each problem
    • Place post-it notes on your flip chart
  • How have these problems affected the university?
  • Report results to full group
summary
Summary
  • What are some of the key considerations for protecting against LAIs?
    • How can we ensure they are being implemented as intended?
