A recent UC Davis study revealed a surprising finding – an inverse relationship between patient satisfaction scores and health outcomes. In other words, those most satisfied with their healthcare providers were, on average, sicker and more likely to die than their less satisfied counterparts! As might be expected from these findings, healthcare costs were also higher – by about 9% – among highly satisfied patients.
The study compared health outcomes and patient satisfaction scores of over fifty thousand adult respondents of the Medical Expenditure Panel Survey, a product of the Agency for Healthcare Research and Quality under the U.S. Department of Health and Human Services. The survey is designed to be representative of the U.S. adult population and is the most comprehensive data set of its kind. Response rates for the survey have varied between approximately 60% to 70% over the last decade.
Among the possible explanations is that physicians, motivated in part by physician compensation structures that consider patient satisfaction, stray from standard treatments and instead meet patient expectations. Under this scenario, patients are satisfied because tests and procedures are viewed in a more-is-better light, but clinical outcomes suffer, e.g., patients receive treatments that carry risk as a result of false positive lab results.
The trend toward elevating patient ratings in measures of quality of care are likely to continue with the Center for Medicare Services (CMS) starting this past December with its initial phase of 1% rewards or penalties for hospitals under Value Based Purchasing. One-third of the evaluation process relies on patient data, i.e., survey data.
These intriguing study findings certainly call for further research to solidify our understanding of the value of patient satisfaction ratings. This study and our firm’s experience especially calls into question the value of very broad measures of patient satisfaction, e.g, how satisfied are you overall, because patients are notorious for confusing bedside manner with the quality of clinical care.
The implications of this study may be far reaching, but enterprising providers can take simple steps to educate their patients, preferably long before they see them in the exam room. With email and social media making communication easier and less expensive, creating simple and regular communications can help inform patients of the possible high costs of unnecessary tests and treatments.
