Improving adherence — common mistakes

In exam answers, do not just describe an intervention. You must explain how it is supposed to improve adherence by linking the strategy to a specific reason for non-adherence. For example, 'A pill organiser with an alarm (behavioural prompt) improves adherence for patients whose non-adherence is caused by forgetfulness.'

When evaluating behavioural interventions, a key strength is their effectiveness for unintentional non-adherence (e.g., forgetting). A weakness is that they may be less effective if the non-adherence is intentional and stems from the patient's beliefs or concerns about the treatment.

To achieve higher marks, link cognitive interventions to concepts from health psychology, such as the Health Belief Model. For instance, explain that providing information about the risks of an untreated illness increases the patient's 'perceived severity', making adherence more likely.

When discussing practitioner-patient communication, you can evaluate it by considering its strengths (e.g., highly individualised, addresses patient's specific concerns) and weaknesses (e.g., can be time-consuming, requires practitioners to have specific communication training).

This is a common misconception. Non-adherence is a complex issue influenced by many factors, including the complexity of the treatment, side effects, communication with the practitioner, and patient beliefs. It is rarely a simple case of a patient deliberately refusing treatment. Interventions are needed to address these multiple barriers, viewing it as a healthcare problem to be solved collaboratively, not a personal failing.

While often used interchangeably, there is a subtle but important difference. 'Compliance' implies a passive model where the patient obediently follows the doctor's orders. 'Adherence' suggests a more active, voluntary choice by the patient to follow the recommended treatment plan. The term 'concordance' takes this further, emphasising a collaborative partnership where the patient and practitioner make a joint decision about treatment. Cambridge exams often use 'adherence', reflecting this modern understanding.

Not necessarily. The effectiveness of an intervention depends on the specific reason for non-adherence. A simple, inexpensive pill organiser (a behavioural prompt) might be highly effective for a patient who is merely forgetful. Conversely, a sophisticated app might be useless for a patient who is non-adherent due to a deep-seated fear of side effects. The best intervention is one that is tailored to the individual patient's needs and barriers, which may well be a low-cost, simple solution.
