Original ArticleMediating Effect of Family Caregivers' Hesitancy to Use Analgesics on Homecare Cancer Patients' Analgesic Adherence

ContextFamily caregivers play an increasingly critical role in cancer patients' symptom management as the number of cancer patients receiving home care grows. However, there is a lack of research measuring the impact of the family caregivers' hesitancy to use analgesics on analgesic adherence and the resulting influence on patient pain intensity.ObjectivesTo examine whether family caregivers' hesitancy to use analgesics is a mediator that influences patient adherence and investigate how analgesic regimen adherence affects pain intensity.MethodsThis study used a cross-sectional and descriptive design. One hundred seventy-six patient-family caregiver dyads (N = 352) were recruited from one local hospital in southern Taiwan. Instruments included the Short Version of the Barriers Questionnaire-Taiwan, the Morisky Medication Adherence Measure-Taiwan, the Brief Pain Inventory-Chinese, and demographic and illness questionnaires. A one-way analysis of variance and post hoc comparisons were performed to assess the influence of analgesic regimen adherence on pain intensity. Sobel tests were used to examine mediating effects.ResultsFamily caregivers' hesitancy to use analgesics was a significant mediator between patient barriers to use analgesics and patient analgesic regimen adherence (P < 0.0001). Patients with low and moderate adherence levels reported significantly higher levels of pain severity (F = 3.83, P < 0.05).ConclusionThis study showed that family caregivers' hesitancy to use analgesics was a significant mediator associated with their hesitancy to use analgesics and the patients' analgesic adherence. It is important for health care providers to consider family caregivers' hesitancy to use analgesics when attempting to improve adherence to pain management regimens in clinical practice.
