Q

what are HCAI costs in Scotland?

how much does it increase the length of stay (LOS)?

how many deaths does HAI cause a year in the UK?

What % of HCAI is preventable?

A

HCAI cost in Scotland is ~£76.5m or 1.1% of the NHS budget in Scotland

HCAI results in average increase in LOS (length of stay) of 7.8 days

3000 deaths in hospital directly related to HAI In the UK

15-30% of HCAI are preventable

Q

what is the Francis report leading to?

what are 2 ways we measure quality of care?

A

the Francis report is leading to paradigm shift in clinical care

how can can measure quality of care:
- health improvement Scotland (HIS)
- rates of HAI

Q

what are SICP’s?

what are standard precautions?

what are TBP’s?

A

Standard Infection Control Precautions (SICP) – Measures necessary to reduce the spread of microorganism from both known and unknown sources of infection e.g ventilation, bed spacing, vaccination

Standard precautions – Precautions we take for any patient e.g hand washing

Transmission Based Precautions (TBPs) – A set of measures used when a patient Is either suspected or known to be infected with a specific infection e.g diarrhoea – we don’t know if it is caused by an infectious agent, or has an inflammatory cause

Q

What are the 3 main modes of transmission?

What does the ability to aerolise depend on?

What medical procedures needed to be used for airborne transmission?

A

3 main modes of transmission:
1) Contact transmission - can be direct or indirect

2) Droplet transmission
* When we breath out, droplets travel a short distance before falling on surfaces

3) Airborne (aerosol) transmission
* Droplets that are less than 5 microns, which can travel a much longer distance than larger droplets
* Droplets this small can also enter alveoli and cause infection there
* Ability to aerosolise depends on the pathogen
* Medical procedures i.e. ventilation technique or specific medical procedures need to be used

3 syndromes that require contact precautions:
1) Gastroenteritis
2) Fever in patient returned from the tropics
3) Patients with open wounds

Q

When are airborne precautions used?

What 1 syndrome requires airborne precautions?

What 3 specific organisms require airborne precautions?

What 5 things does airborne precaution involve?

A

Airborne precautions are for particles that are <5 microns

They can be widely dispersed

FFP3 mask for all aerosol generating procedures (AGP) - medical procedures that can result in the release of aerosols from the respiratory tract e.g bronchoscopy

3 specific organisms that require airborne precautions:

1) TB
2) Chicken pox
3) Measles

5 things airborne precaution involves:

1) Single room
2) Disposable apron or consider gown if manoeuvring the patient
3) Disposable gloves
4) High efficiency filter mask (FFP3 mask)
5) Eye protection

Q

What are the 2 before and 3 afters of hand decontamination?

When can alcohol gel be used?

When does soap and water need to be used?

What are the 6 steps to hand decontamination?

A

2 befores of hand decontamination:
1) Before touching a patient
2) Before clean/aseptic procedure

3 afters of hand decontamination:
1) After body fluid exposure risk
2) After touching patient
3) After touching patient surroundings

Alcohol gel can be used between patients if hands sociably clean

After about 4 consecutive uses of alcohol gel, we need to wash hands to remove build-up of dried gel

Must use soap and water after examination of a patient with diarrhoea and after removing gloves

6 steps to hand decontamination:
1) Bare below the elbows plus removal of watches and rings with stones
2) Wet hands and then apply soap to all surfaces of the hands
3) Rinse hands
4) Dry hands on paper towels
5) Turn off tap with elbows or paper towel
6) Dispose of towel without contaminating hands

Q

What are the 3 factors in the vicious cycle of infection?

What are 4 bacteria where we have to double check treatment plan?

A

3 factors in the vicious cycle of infection:
1) Bacterial infection
2) Antimicrobial usage
3) Antimicrobial resistance

4 Bacteria where we have to double check treatment plan:
1) Methacillin resistant S. aureus (MRSA) – gram positive
2) Vancomycin Resistant Enterococcus (VRE) – gram positive
3) Carbapenemase Producing Organism (CPO) – gram negative
4) Extended Spectrum B-lactamse (ESBL) – gram negative

What is the GMCs stance on vaccination status?

A

As Healthcare professionals, we need to know our vaccination status

We can’t be forced to get vaccinated, but refusal then may affect the jobs we take up
