Impact of a clinical pharmacist on optimising the quality use of medicines according to the acute coronary syndrome (ACS) secondary prevention guidelines and medication adherence following discharge in patients with ACS in Sri Lanka: a prospective non-randomised controlled trial study protocol

Abstract

ObjectivesEnsuring quality use of medicines (QUM) through clinical pharmacy services can improve therapeutic outcomes of patients diagnosed with acute coronary syndrome (ACS). The major objective of this study is to demonstrate the added value of a clinical pharmacist to the medical and nursing team providing care to patients with ACS on the continuation of quality use of the patients’ medicine after discharge.Study designThis protocol outlines a prospective, non-blinded, non-randomised, controlled interventional study.Study settingThe study will be conducted at the professorial medical wards of a tertiary care teaching hospital in Sri Lanka.ParticipantsSample size will be 746 patients in both control and intervention arms. Patients diagnosed with ACS who are 18 years old or above and expected to visit the hospital for their routine clinic follow-ups after discharge will be recruited and randomised 1:1 to either the intervention group or the control group. Patients who are diagnosed and suffering from psychological disorders will be excluded from this study.InterventionsThe planned interventions that will be delivered at discharge include review and optimisation of medications, assessing patient adherence and providing discharge medication counselling. Data will be collected at recruitment, 1 month, 3 months and 6 months’ time intervals in both groups. Improvement of patients’ medication adherence, reduction of hospital readmissions, reduction of drug-related problems, the attitude of doctors and nurses towards clinical pharmacy services and the cost-effectiveness of the clinical pharmacy services will be the major outcomes of this study.Ethics and disseminationEthical approval for this study has been obtained from the ethics review committee, Faculty of Medicine, University of Peradeniya (2019/EC/26) and the trial is registered at the Sri Lanka Clinical Trials Registry. The results of this study will be disseminated via conference proceedings, journal publications and thesis presentations.Trial registration numberSLCTR/2019/039.
