Evaluation of explicit criteria for total hip joint replacement.
We tested an appropriateness of indications tool for total hip joint replacement in patients with osteoarthritis. Criteria were developed using a modified Delphi panel judgment process. Ratings were analyzed regarding level of agreement among panelists. Another panel rated the same indications; results were compared with the main panel. Test-retest of the main panel was performed. Regression models were used to assess the contribution of each algorithm variable. Appropriateness indication judgment was applied to 84 patients and compared to health-related quality-of-life improvement before and 3 months following intervention. Main panel ratings compared to those of a second panel resulted in a kappa statistic of 0.77. Test-retest kappa for the main panel was 0.81. Patients considered appropriate candidates for surgery, based on their composite indication scores, showed more improvement in health-related quality of life after 3 months than those considered inappropriately by composite indication scores. The previous parameters tested showed acceptable results for an evaluation tool. These results support the use of this indications algorithm as a screening tool for assessing the appropriateness of hip replacement surgery in osteoarthritis.
