Effects of home drug delivery on drug-related problems: preliminary evidence for improved patient outcomes during the COVID-19 pandemic in Thailand.

ABSTRACT

BACKGROUND: Drug-related problems cause severe disabilities, premature deaths, and unnecessary costs. Telepharmacy offer easier access to needed medications, preventing DRPs. Adoption has been slow, and it is unclear what aspects of telepharmacy are most important. The COVID-19 pandemic disrupted health services, forcing the rapid adoption of telepharmacy. In Phayao, Thailand, a program was implemented for home delivery of drugs for patients with chronic disease. OBJECTIVES: This study aimed to explore the prevalence and factors associated with DRPs of patients with chronic disease who received home drug-delivery services. METHODS: A cross-sectional study was undertaken in Phayao Province located in North Thailand. Simple random sampling was used to select patients from 6 public hospitals between July and August 2020. Logistic regression was used to analyze multivariate factors that might be related to DRPs. RESULTS: A total of 246 participants reported at least 1 DRP (49.30%). Most participants were female (58.32%) with elementary education (60.72%). Their mean age was 63.69 (SD = 12.97) years. The 5 most common DRPs were changes of drug packaging or drug brands (18.84%), leftover medications of more than 2 weeks (18.44%), nonadherence (17.43%), having conditions or diseases requiring additional medications (6.81%), and adverse drug reactions (5.21%). Univariate analysis identified number of chronic conditions, diabetes mellitus, dyslipidemia, chronic kidney disease, education level, and drug-delivery channel as predictors of DRPs. In multivariate analysis, predictors of DRPs were the number of drugs used per day (adjusted odds ratio [aOR] 1.11 [95% CI 1.03-1.19], P = 0.004) and dyslipidemia (aOR 1.83 [95% CI 1.18-2.84], P = 0.007). Nonadherence was associated with leftover medicines (aOR 4.22 [95% CI 2.44-7.28], P < 0.001) CONCLUSION: The present results indicate that home delivery caused no increase and may have caused a decrease in DRPs, and patients were highly satisfied. These promising results suggest that home delivery should be continued and further investigated even as the COVID-19-induced emergency subsides.
