Define patient compliance
Extent to which the patients behaviour coincides with medical or health advice
Give three disadvantages of patient compliance

Define patient adherence
The extent to which the patients actions match agreed recommendations - more patient centred
What is the difference between patient adherence and patient compliance
Adherence is more patient centred, empowers patients and considers them as equals in care
What are the 6 key principles of adherence

Describe the necessity-concerns framework
Looks at what influences adherence - adherence increases when necessity beliefs are high and concerns are low
Give 2 factors that patient centred care encourages

2. Shared control of the consultation so decisions are made by patient and doctor together
What is concordance
Expectation that patients will take part in treatment decisions and have a say in the consultation
Give 5 barriers to concordance
- Patient may not want to engage in discussions with doctor
- May lead to worry
- Patients may just want their doctor to tell them what to do
- Time, resources and organisational constraints
- Challenging, patient choice may differ from medical advice
Give 4 advantages of doctor patient communications
- Better health outcomes 3
- higher compliances to therapeutic regimes
- higher patients and clinician satisfaction
- Decrease malpractice risk
Name 6 examples of non-adherence
- Not taking prescribed medication
- Taking bigger/smaller doses than prescribed
- Taking medication more/less often than prescribed
- Stopping medicine without finishing course
- Modifying treatment to accommodate other activities
- Continuing with behaviours against medical advice (Diet, alcohol, smoking)
What are some unintentional reasons for non adherence

What are some of the intentional reasons for non-adherence
Patient beliefs about their health and condition
Beliefs about treatments
personal preferences
Perceptual barriers
