摘要: Background: A high quality decision requires that patients who meet clinical criteria for surgery are informed about the options (including non-surgical alternatives) and receive treatments match their goals. The aim of this study was to evaluate psychometric properties sensibility a patient self report instrument, measure decisions total joint replacement knee or hip osteoarthritis. Methods: performance Hip/Knee Osteoarthritis Decision Quality Instrument (HK-DQI) evaluated in two samples: (1) cross-sectional mail survey with 489 77 providers (study 1); (2) randomized controlled trial aid 138 osteoarthritis considering 2). HK-DQI results scores. Knowledge items summed create knowledge score, set goals concerns used logistic regression model develop concordance score. score measures proportion whose treatment matched Hypotheses related acceptability, feasibility, reliability validity scores were examined. Results: In 1, completed by 382 (79%) 45 (58%), 2 127 (92%), low rates missing data. DQI-knowledge reproducible (ICC = 0.81) demonstrated discriminant (68% vs. 54% control, 78% 61% patients) content validity. predictive validity, as concordant had more confidence less regret compared those did not. Conclusions: is feasible acceptable patients. It can be assess whether making
