The Role of Pharmacists in Home Health Care: A Study Set in a Regional Hospital in Taipei City

In response to population aging, there is an increase in demand for the coverage of and the necessary services provided by home health care and home care for socially vulnerable groups. This study explored whether the instructions and recommendations offered by pharmacists during their home visits play a key role in the factors that influence a patient’s prognosis. A home health care database was analyzed in this study. The subjects received home visits from pharmacists. There were 262 subjects following the exclusion of closed cases that were not due to improved outcomes or death. To validate the research framework, multiple regression analysis was employed for model validation. The level of consciousness and Barthel Index score mediated the effects of multimorbidities, and these mediating effects significantly affected patient outcomes (improvement or death). The medication-related knowledge and instructions for correct medication use provided by pharmacists did not exhibit significant moderating effects on the influence of a patient’s level of consciousness and Barthel Index score on their improved outcomes. However, the pharmacists’ provision of instructions and recommendations for patient self-care had significant moderating effects on the path by which patients with multimorbidities experienced improved outcomes through higher total Barthel Index scores. In comparison with physician home visits, which merely cover the treatments for diseases, pharmacists also play a vital role in home health care. Pharmacists provide patients with medication-related knowledge and instructions for correct medication use. This study addressed aspects that have not been considered in previous studies.
