What publicly available quality metrics do hip and knee arthroplasty patients care about most when selecting a hospital in Maryland: a discrete choice experiment

OBJECTIVE: To quantify which publicly reported hospital quality metrics have the greatest impact on a patient’s simulated hospital selection for hip or knee arthroplasty. DESIGN: Discrete choice experiment. SETTING: Two university-affiliated orthopaedic clinics in the greater Baltimore area, Maryland, USA. PARTICIPANTS: One hundred and twenty-eight patients who were candidates for total hip or knee arthroplasty. PRIMARY AND SECONDARY OUTCOME MEASURES: The effect and magnitude of acceptable trade-offs between publicly reported hospital quality parameters on patients’ decision-making strategies using a Hierarchical Bayes model. RESULTS: Publicly reported information on patient perceptions of attention to alleviation of postoperative pain had the most influence on simulated hospital choice (20.7%), followed by methicillin-resistant Staphylococcus aureus (MRSA) rates (18.8%). The understandability of the discharge instructions was deemed the least important attribute with a relative importance of 6.9%. Stratification of these results by insurance status and duration of pain prior to surgery revealed that patient demographics and clinical presentation affect the decision-making paradigm. CONCLUSIONS: Publicly available information regarding hospital performance is of interest to hip and knee arthroplasty patients. Patients are willing to accept suboptimal understanding of discharge instructions, lower hospital ratings and suboptimal cleanliness in exchange for better postoperative pain management, lower MRSA rates, and lower complication rates.
