Abstract
BACKGROUND: Understanding patient preferences and desire for involvement in making medical decisions is important when managing chronic conditions. Previous studies have used the Autonomy Preference Index (API) in younger patients with asthma to evaluate these preferences. OBJECTIVE: To identify factors associated with autonomy and to determine whether autonomy is related to asthma outcomes among older adults. METHODS: A total of 189 older adults (>55 years old) with persistent asthma were included. Preferences for autonomy were assessed using the API, with a higher score indicating higher desire for autonomy. Scores were separated into 2 domains of information-seeking and decision-making preferences. The separated scores were correlated with asthma outcomes and demographic variables. To control for confounding factors, a linear regression analysis was performed. RESULTS: Higher decision-making preference scores correlated with female sex (P = .007), higher educational level (P = .01), and lower depression scores (P = .04). Regarding outcomes, decision-making scores positively correlated with Mini Asthma Quality of Life Questionnaire (Mini-AQLQ) scores (P = .01). On linear regression analysis, the Mini-AQLQ score remained significantly associated with decision-making preference scores (P = .03). There was no association with asthma control test scores, spirometry values, and health care use. Information-seeking preference scores correlated with educational level (P = .03), but there was no correlation with asthma outcomes. CONCLUSION:Older adults with asthma and a greater desire for involvement in decision making have better asthma-related quality of life. Future studies with the intention to increase patient autonomy may help establish a causal relationship.
