Background: Understanding patients' preferred role in decision making can improve patient-centered care. This study aimed to determine change and the predictors of change in preferred decision-making roles over time in patients with heart failure.
Methods and results: During the CASA (Collaborative Care to Alleviate Symptoms and Adjust to Illness) trial, patients' preferred roles in decision making were measured using the Control Preferences Scale (range 1-5; higher = less active; n = 312) at 4 timepoints over 1 year. The effect of the CASA intervention on preferred decision-making roles was tested using generalized linear mixed models. Whether preferences changed over time in the whole population was determined using linear regression. Demographic and health-related factors were examined as predictors of change using multiple linear regression. At baseline, most participants preferred active (score 1-2, 37.2%) or collaborative (score 3, 44.9%) roles. The CASA intervention did not influence preferred decision-making roles (P > 0.1). Preferences significantly changed over 1 year (P < 0.01), becoming more active (82.1%, 84.2%, 89.0%, 90.1% active/collaborative at each timepoint). Among all models and covariates, there were no significant predictors of change (P > 0.1).
Conclusions: Patients' preferred roles in decision making change over time, but changes are not well predicted. Clinicians should frequently and directly communicate with patients about their preferred decision-making roles.
