20
Q

What are the disadvantages of direct observation of adherence?

A

Expensive

Limited to use in clinical practice

Invasive

21
Q

Give four examples of indirect measures of adherence

A

Pill counts

Mechanical or electrical measures of dose dispensing

Patient self-report

Second-hand reports

22
Q

What is the advantage of pill counts?

A

More objective than self / other-reports

23
Q

What is the disadvantage of pill counts?

A

Still subject to inaccuracy (e.g. Lost pills)

24
Q

What are the advantages of mechanical or electrical measures of dose dispensing?

A

Objectively measures whether a dose has been dispensed

More accurate than other indirect measures

25
Q

What is the disadvantage of mechanical or electrical measures of dose dispensing?

A

Doesn’t measure if the dispensed medication was actually taken

26
Q

What are the advantages of patient self-report?

A

Easy to obtain

Inexpensive

27
Q

What are the disadvantages of patient self-reports?

A

Prone to inaccuracies/bias

Tendency to over-report adherence

28
Q

What are the advantages of second-hand reports?

A

Similar to self-reports

29
Q

What are the disadvantages of second-hand reports?

Q

How can severity of illness affect adherence?

A

With less serious diseases, patients in poorer health are more likely to be adherent.

With more serious diseases, patients in poorer health are less likely to be adherent.

Consequences

35
Q

What parts of preparation for treatment can affect adherence?

A

Treatment setting

Q

What immediate characteristics of treatment can affect adherence?

A
