L4.5 infection control in the workplace Flashcards
how can people protect themselves in the workplace
direct protection through immunisation and prophylactics
what are environmental factors to prevent infections in the workplace
prevent and reduce contact between agent and host such as PPE
how can reduce agents
isolating cases
why are workplaces an environment of high pathogen transmission and contamination
high interaction, ventilation, shaped resouces and enquipment
what are formites
an inanimate object that can carry & spread disease & infectious agents
Common challenges of healthcare environments include:
- High use of antimicrobial agents
- High prevalence of antimicrobial resistant organisms
- High use of invasive devices/procedures
- Immobile patients
what is included on the chain/spread of infection model
pathogen, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host
what are the portals of entry
inhalation, ingestion, absorption, inoculation, trans-placental, introduction
what are the common objects which have high
contamination risks
aprons, gloves, gowns, face protection
what are the stages of environmental control (decontamination)
cleaning - enhanced cleaning - disinfection - sterilisation
what are negative pressure isolation
the room can control its own air to prevent contaminated air mixing with ‘clear’ air
when is cohort nursing undertaken
when there are not enough single rooms to isolate patients they all isolate together
