Abstract 10862: The Effects of a New Medication Monitoring Programme on Blood Pressure Control Among Elderly Home Residents With Multiple Medications
Objective: A high prevalence of hypertension among the elderly has raised public concern in Asia particularly in Hong Kong. It is commonly observed among elderly being prescribed with more than one antihypertensive agent. However, poor adherence can serve as one of the major causes of suboptimal blood pressure (BP) control, and particular in elderly homes where the residents often lack family support. The study aimed to evaluate the effects of a new medication monitoring programme on BP control among elderly home residents with multiple medications.
Methods: We recruited study subjects from three elderly homes enrolled in a pharmacist-led home-based medication monitoring programme launched by the Hong Kong Pharmaceutical Care Foundation. The programme aimed to optimise drug therapy and achieve better BP control. We used a cluster sampling to recruit elderly people (aged ≥65 years) prescribed with multiple medications, who were then followed up for six months. Subjects in the intervention group received medications under pharmacist-led medication monitoring programme, while the control group received usual care. Intention-to-treat analysis was adopted. Systolic BP and diastolic BP were measured at each 3-monthly follow-up as primary outcomes. Secondary outcomes included healthcare utilisation and staff satisfaction. Repeated measures analysis of variance (RMANOVA) was used to estimate the intervention effect after adjusting for other covariates.
Results: A total of 290 residents were recruited. The study showed distinct patterns of changes in SBP and DBP between groups. After 6 months, participants in the intervention group (n=200) had an average of 5.16mmHg (p=0.134) and 2.66mmHg (p=0.198) decrease in SBP and DBP, respectively; while the control group (n=90) showed 12.40mmHg (p=0.027) and 6.60mmHg (p=0.061) increase in SBP and DBP, respectively, after adjusting for other covariates.
Conclusions: Elderly home residents enrolled in this new pharmacist-led home-based medication monitoring programme had better BP parameters, suggesting that future programmes on other cardiovascular disease medications based on similar approach could potentially be effective in achieving favourable outcomes among the elderly population in primary care.
