Flashcards in control of infection in hospital Deck (14):
1

routes of transmission of disease

airborne
droplet (same as airborne but bigger particles)
direct contact
indirect contact
percutaneous

2

define HCAI

healthcare associated infection

3

define ANTT

aseptic non touch technique

4

2011 levels of HCAI
a. nationally
b. in UH bristol

a. nationally: 6.4%
b. in UH bristol: 8.5%

5

2015 limits on HCAI of
a. MRSA
b. MSSA
c. c difficile
d. e coli

a. MRSA: 0
b. MSSA: 25
c. c difficile: 45
d. e coli: none set

6

6 infection alerts on medway

MRSA
c difficile
ESBL (extended-spectrum beta-lactamases)
GRE (glycopeptide-resistant enterococci)
tuberculosis
multi-resistant organisms

7

when to use
a. soap and water 3

-around pts with diarrhoea
-before/ after care episodes
-after removing gloves

8

when NOT to use alcohol gel and why

pts with diarrhoea (c diff/ norovirus) bc does not kill spores and non-envelope viruses

9

how long does the following survive:
a. gram + (enterococcus inc VRE, staph aureus inc MRSA, strep pyo
b. gram - (actinobacter, e coli, klebsiella, psuedomonas)
c. bordetella pertussis, proteus
d. mycobacteria inc TB
e. c diff spores
f. candida albicans
g. RTIs (influenza, SARS)
h. GI tract (rotavirus, polio):
i. blood borne (HBV/ HCV)
j. herpes viruses

a. gram + (enterococcus inc VRE, staph aureus inc MRSA, strep pyo: months on dry surfaces
b. gram - (actinobacter, e coli, klebsiella, psuedomonas): months, often more than gram +
c. bordetella pertussis, proteus: days
d. mycobacteria inc TB: months
e. c diff spores: 1 year
f. candida albicans: 4 months
g. RTIs (influenza, SARS): minutes-days
h. GI tract (rotavirus, polio): 2 months
i. blood borne (HBV/ HCV): >1 week
j. herpes viruses: few hours-7 days

10

colonisation v infection

colonisation: microbe which establishes and multiplies in particular environment eg body surface WITHOUT producing disease/ symptoms

infection: microbe which establishes and multiplies in particular environment eg body surface WITH SYMPTOMS

11

is MRSA very pathogenic

no more than staph aureus, but its resistant to most common antibiotics

12

is MRSA common in mouth

no
occasionally isolated from oral infections

13

chance of acquiring disease through sharps injury if not vaccinated:
a. hep B
b. hep C
c. HIV

a. hep B: 1/3
b. hep C: 1/30
c. HIV: 1/300 (also post-exposure prophylaxis v effective)

14

what disease is the main reason wards get closed
details about this disease

norovirus
highly infections. 12-48 hours incubation, lasts about 48 hours (diarrhoea and vomiting)
stay off work for 48 hours after last symptom
