3
Q

What is the adherance with common conditions like?

A
  • Wider economic burden

5
Q

How can we measure adherance?

A

Directly - Urine or blood test

Indirectly - Pill counts, mechanical measures of dose, patient self-report, second hand report like doctors and carers

6
Q

What are the issues with measuring adherance?

A

Direct: Cost, limited to use in clinic, can take medicine but doesn’t mean it is as prescribed and taking every day

Indirect: Hard to compare studies for different conditions, just because no pill can’t prove it has been taken or been lost, issues with recall, bias, overreporting adherance

7
Q

Why do patients non-adhere?

A

- Unintentional: patients want to adhere but can’t due to factors out of their control, e.g cost, poor recall, difficulties administering

- Intentional: patient doesn’t want to based on their beliefs, attitudes and experiences

8
Q

How does recall affect adherance?

A

The more a patient can remember about their condition and the instructions, the more likely they are to adhere so need to make treatment simple

A
  • Educate patient on medicine and disease
  • Simplify treatment regime
  • Physical aids and reminders
10

A
  • Don’t realise severity of disease
  • Lack of symptoms so don’t want side effects

A
  • Concordance
  • Adress patient misconceptions
