Abstract
Background: For older adults, the capacity to self-manage medications may be limited by several factors. However, currently available tools do not permit a comprehensive assessment of such limitations. The Domain Specific Limitation in Medication Management Capacity (DSL-MMC) was developed to address this need. This study aimed to establish the face and content validity of the DSL-MMC. Methods: The DSL-MMC tool consisted of 4 domains and 12 sub-domains with 42 items including: 1. physical abilities (vision, dexterity, hearing); 2. cognition (comprehension, memory, executive functioning); 3. medication regimen complexity (dosing regimen, non-oral administration, polypharmacy); and 4. access/caregiver (prescription refill, new prescription, caregiver). Pharmacists assessed each item for relevance, importance, readability, understandability, and representation. Items with content validity index (CVI) scores of <0.80 for relevance were examined for revision or removal. Results: Twelve pharmacists participated in the study. CVI scores for relevance and importance of domains were 1.0; of the sub-domains, two were below 0.80. Among the 42 items, 35 (83%) and 30 (71%) maintained CVI scores above 0.80 for relevance and importance, respectively. Five items were removed, three were merged and seven were modified due to low CVI scores and/or feedback. Conclusion: The DSL-MMC has been validated for content.
Highlights
Canada’s population has been aging steadily as noted by the annual increase in mean age since record keeping began in 1971
The objective of the Domain Specific Limitation in Medication Management Capacity (DSL-MMC) is to measure the impact of domain specific limitations on the medication management capacity of older adults
We developed the tool by reviewing the published literature pertaining to both factors that impact, and tools that assess medication management capacity
Summary
Canada’s population has been aging steadily as noted by the annual increase in mean age since record keeping began in 1971. By 2025, it is projected that 1 in 5 Canadians will be an older adult, and by 2059, 25% of the population will be composed of seniors [1]. These remarkable statistics speak to the need for pharmacists to gain expertise in the healthcare needs of an aging population, which differs from that of the general population. The capacity to self-manage medications may be limited by several factors. The Domain Specific Limitation in Medication Management Capacity (DSL-MMC) was developed to address this need.
