Biology Unit 6 - HAIs

HideShow resource information
What are HAIs
Hospital acquired infections
1 of 11
When are the caught?
When patient treated in hospital
2 of 11
How can they be transmitted?
1) Staff and visitors not asking hands before and after visiting patient 2) Coughs and sneezes not being contained 3) Equipment/surfaces not being disinfected after used
3 of 11
Why are people more likely to catch them in hospital?
Many of the patients are ill and so have weakened immune systems
4 of 11
3 codes of practice to prevent?
1) Staff and visitors encouraged to wash hands before & after 2) Equipment and surfaces should be disinfected after use 3) People with HAIs should be moved to isolated hard to prevent spread
5 of 11
How are some of them caused?
By bacteria that are resistant to antibiotics
6 of 11
Example?
MRSA
7 of 11
Why are these difficult to treat?
Because antibiotics don't get rid of them
8 of 11
Why are infections caused by antibiotic resistant bacteria more common in hospitals?
More antibiotics are used there, so bacteria are more likely to have evolved resistance
9 of 11
Codes of practice to prevent and control antibiotic resistant HAIs
1) Shouldn't be prescribed antibiotics for minor bacterial/viral infections 2) Shouldn't prescribe antibiotics to prevent infections 3) Should use narrow-spectrum of antibiotics 4) could rotate use of different antibiotics
10 of 11
cont.
5) Patients should take all antibiotics prescribed so infections fully cleared
