Abstract

Introduction: Unpaid carers are an increasing proportion of the UK population. One of the many ways in which they help those they care for is assisting with medication adherence. Many older adults have medicines dispensed in pharmacy-filled multi-compartment medication compliance aids (pMCAs). However, evidence suggests that pMCAs may increase medication-related harm, and little is known about the interaction between the user, medication adherence systems and the carer.

Aim: To explore the views of carers supporting older adults to manage their medications with and without a pMCA.

Method: A researcher-administered questionnaire survey of carers supporting older adults to manage their medicines with or without a pMCA. Participants were recruited from inpatient wards, outpatient clinics and community services in central London. Responses were analysed by two independent researchers to identify overarching themes.

Results: Eighty-eight unpaid carers were interviewed and responses were categorised according to the medication adherence method used; 47 supported a user with a pMCA and 41 supported without a pMCA. The main themes were: Time, Responsibility and Mistakes, Waste and Sustainability, and Polypharmacy, with sub-themes of design of multi-compartment medication compliance aids, organisation and reassurance.

Conclusion: Supporting medication adherence puts considerable burden on carers regardless of whether a self- or pharmacy-filled medication compliance aid is used or not. Prescribers could alleviate this burden through regular medication review by considering the prescribing frequency and duration and medication rationalisation. Redesign of both pMCAs and systems surrounding their use could also help reduce carer's burden and environmental burden.
