Brief Summary

Background Medication adherence following acute coronary syndrome (ACS) is often sub-optimal and is associated with poor clinical outcomes. Non-adherence can be considered intentional or unintentional. Findings ways to improve adherence is an important area of research with widespread clinical implications, however, previous interventions have generally been ineffective. The investigators propose an intervention that challenges both intentional and unintentional non-adherence in patients hospitalised following ACS.

Objectives The objective of this study is to determine the feasibility of a hospital-based intervention aimed at supporting medication adherence in patients following an ACS.

Methods Patients admitted to hospital with an ACS will be recruited for this study. The study will target both intentional and unintentional non-adherence over two sessions through challenging treatment beliefs and formulating specific action plans to encourage habit formation. Patients will be asked to provide in-depth feedback around the acceptability of the intervention. As this is a feasibility study, outcomes (i.e. medication adherence) will not be collected.

Dissemination If this study seems to be practical to deliver and acceptable to patients then it will inform the design of a future randomized-controlled pilot study to test the effectiveness of the intervention delivered by hospital pharmacists on a study outcome (i.e. medication adherence).

Detailed Description

Intervention details

• All stages of the intervention will take place during hospitalization.
• Firstly, patients will complete a questionnaire based on the Beliefs about Medication Questionnaire-Specific (BMQ-S) (Horne & Weinmen, 1999).
• Patients responses to this questionnaire will form the basis of Session 1 where beliefs about medicines will be discussed. The aim is to identify any negative or erroneous beliefs patients have that may prevent them from taking their medicines after they leave the hospital.
• Session 2 will focus on developing specific action plans for taking medication at home. Patients will be asked to formulate an if-then plan ('If it is time X in place Y and I am doing Z, then I will take my pill dose'. The aim is to make taking their medicines as much a part of their daily routine as possible.
• Prior to discharge, patients will complete the beliefs questionnaire again to see if there has been any shift in their beliefs about medications.
• Patients will also be asked to provide detailed feedback about the study. The investigators want to know whether the intervention setting (i.e. hospital-based), timing (i.e. straight after an ACS), content (i.e. targeting both intentional and unintentional non-adherence) and interventionist (i.e. PhD candidate) seem to be acceptable to patients.
• Feedback will be gathered after completion of the intervention and also during a follow up phone call 2-3 weeks after discharge.

Study Groups

Intervention

Group Type: EXPERIMENTAL

Intervention group

Intervention Type: BEHAVIORAL

All stages of the intervention will take place during hospitalization. Patients will complete a questionnaire about their personal beliefs about medicines. Patients responses to this questionnaire will form the basis of Session 1 where beliefs about medicines will be discussed. Any negative beliefs or concerns will be discussed and beliefs about drug necessity will be encouraged.

Session 2 will focus on developing specific action plans for taking medication at home. Patients will be asked to formulate an if-then plan ('If it is time X in place Y and I am doing Z, then I will take my pill dose').

Prior to discharge, patients will complete the beliefs questionnaire again to see if there has been any shift in their beliefs about medications. Patients will also be asked to provide detailed feedback about the study. The investigators want to know whether the intervention setting, timing, content and delivery method seem to be acceptable to patients.
