Introduction :
Considering the prevalence of hypertension among elderly, treatment adherence is crucial in preventing disease progression.
Objectives :
To compare effect of pharmacist-initiated behaviour and cognitive focused counselling (PBCC) program and routine care on treatment adherence in high-risk elderly with hypertension.
Methodology :
This retrospective cohort study was conducted in April 2022 by retrieving data of a pharmacist-initiated counselling service, from 1 October 2021 to 31 March 2022, by accessing the service records and electronic health system. The single-centre service was provided in specialist outpatient clinic at a local public hospital. Patient, who aged 60 years or older with prescription of 8 or more medications (with at least 1 antihypertensive), would receive this service if being non-adherence to antihypertensive treatment. A pharmacist-initiated counselling, focusing on importance of adherence, behaviour intervention and cognitive intervention, was provided to patients with the aim of improving treatment adherence and enhancing medication understanding. The primary outcome was the mean difference of Hill-Bone Compliance to High Blood Pressure Therapy Scale (HB-HBP) change between pharmacist counselling (PC) and routine care (RC) group. Medication knowledge, as assessed by Medication Knowledge Evaluation Tool (MKET), blood pressure and satisfactory level were secondary outcomes.
Result & Outcome :
A total of 60 patients completed the service and were included in this study (36 males [60%]; mean [SD] age, 74.6 [6.9] years). 31 of them were received PC and 29 of them received RC. A significant difference of HB-HBP improvement was seen between PC and RC group (-3.326; 95% CI, -4.108 to –2.544; P<0.01). PBCC also significantly improved the medication knowledge (2.561; 95%CI, 1.883 to 3.239; P<0.01). However, no significant change in SBP was observed (-2.506; 95%CI, -6.207 to 1.195; P=0.181). Change in DBP was found to be significantly higher when comparing to patient who received RC (-4.605; 95%CI, -8.292 to –0.918; P=0.15).
