To determine if psychosocial status influences treatment satisfaction, a quality-of-care indicator, of patients who were hospitalized for acute myocardial infarction (AMI).
Psychosocial variables (social support, dispositional optimism, and depression) were assessed in 1847 AMI patients who completed a 1-month assessment in Prospective Registry Evaluating Myocardial Infarction: Events and Recovery (PREMIER), a multicenter, prospective cohort study. Patients' treatment satisfaction was determined using the Treatment Satisfaction scale of the Seattle Angina Questionnaire. The association between psychosocial variables and treatment satisfaction—adjusted for site, sociodemographics, medical history, clinical presentation, and treatment procedures—was evaluated using a censored normal model.
Study participants were primarily white (77.6%) and male (68.8%), with a mean age of 60.6 ± 12.7 (SD) years. Satisfaction with posthospitalization treatment following AMI increased as social support (Wald χ2 = 35.02, p < .001) and dispositional optimism (β = 1.42; 95% CI 0.24, 2.60) increased. Participants with mild (−3.10, 95% CI −5.77, −0.44), moderate (−4.77, 95% CI −8.16, −1.38), moderately severe (−8.49, 95% CI −13.47, −3.52), and severe (−11.65, 95% CI −18.77, −4.53) depression had significantly worse treatment satisfaction compared with the nondepressed participants.
Assessing psychosocial variables, such as social support, dispositional optimism, and depression severity before hospital discharge, may indicate who is likely to be more satisfied with posthospitalization cardiac care 1 month following AMI. Without controlling for psychosocial status, treatment satisfaction may be a biased indicator of quality. Future studies should evaluate whether psychosocial intervention after AMI can improve satisfaction.
