Abstract
Lack of adherence to analgesic treatment has been identified as a significant barrier to pain management in cancer patients. Currently, there is no perfect standard to measure analgesic adherence; each metric has its strengths and weaknesses and the relationships among subjective and objective measures of adherence have not been fully elucidated. The objective measures of adherence are costly and time-intensive, thus understanding these relationships have important implications. This longitudinal study employed both ‘subjective’ (Morisky Medication-Adherence-Scale, MMAS, which has intentional and unintentional subscales; VASDOSE, 1-item-scale that assesses percentage analgesic doses taken in the index period) and ‘objective’ measures (Medication-Event-Monitoring-System, MEMS®- a microelectronic adherence monitoring system) to understand the relationship between stated-adherence and actual-adherence among a sample of African Americans and Whites with cancer pain.
