Abstract
Consumer satisfaction ratings of health care quality represent a commonly used measure of health care performance. Identifying factors associated with ratings will help us understand the relative influence of individuals' sociodemographic and health characteristics on satisfaction level, thus informing policy making and clinical practice. Existing research has yielded mixed results on key predictors of consumer ratings. Using nationally representative data, this study aims to identify factors associated with Americans' ratings of health care quality. Data from 2008 Health Information National Trends Survey (HINTS) were analyzed using weighted multinomial logistic regressions to estimate consumer ratings. Predictor variables included demographics, health status, care access, and attitude and perceptions about health. Overall ratings were positively skewed; 70% of respondents rated care as "excellent" or "very good." Minority race, psychological distress, not having had cancer, not having a regular health care provider, not having health insurance, lacking confidence in self-care, and avoidance of doctors were significantly associated with lower ratings. The study identifies the psychosocial characteristics associated with lower consumer ratings. The results highlight the importance of using multiple approaches to assess quality of care, including considering patient characteristics, and contribute to the evidence base for evaluating overall quality of care at the dawn of health care reform.
