to prevent a disease from occurring

the proportion of people with the disease who are correctly identified by the

true pos/true +false pos)

the proportion of people with a negative test result who do not have the disease
true neg/false+true neg)

the number of new cases within a specified time period divided by the size of the population
initially at risk

52
Q

wilson & jugner criteria for screening

A

THE CONDITION
it should be an serious health problem
the aetiology should be well understood
there should be a detectable early stage
• THE TREATMENT…
there should be an accepted treatment for the disease
facilities for diagnosis and treatment should be available
there can’t be an unmanageable extra clinical workload
• THE TEST
a suitable test should be devised for the early stage
the test should be acceptable for the patients
intervals for repeating the test should be determined
• BENEFITS
there should be an agreed policy on whom to treat
the cost should be balanced against the benefits

53
Q

selection bias

A

people who choose to participate in screening programmes may be
different from those who do not

54
Q

lead time bias

A

screening merely identifies the disease earlier than before and thus gives
the impression that survival is prolonged

55
Q

length-time bias

A

diseases with longer period of presentation are more likely to be
detected by screening than the ones with shorter time of presentation.

56
Q

what is an error

A

any preventable event that may cause or lead to patient harm

57
Q

medical error

A

• leads to one of two outcomes:
adverse event: an incident which results in harm to a patient
near miss: an event which has the potential to cause harm but fails to develop
further, thereby avoiding harm

58
Q

types of human error

skilled person professing)

59
Q

skill based errors

A

when performing a routine task that is well learnt (automatic)
ii little attention given, thus if distracted - slips of action / memory lapses

60
Q

rule/knowledge based errors

A

an incorrect plan or course of action is chosen (no experience)
mistakes more likely when the tasks are more complex

61

violations

Q

approaches to managing errors

individual people in the system
• The system approach - organisational - adverse events are product of many causal factors
(Swiss-cheese theory) - the whole system is to blame

64
Q

benefits of teamworking

A
  • improving the service delivery
  • improving the decision-making
  • reducing the error
65
Q
