One high quality study (Gordon, Frumento, et al) employed the Charnley comorbidity classification and the EQ5D generic health outcome questionnaire in the Swedish Hip Registry of over 28,500 THA patients. Inferior THA results were demonstrated in a specific subset of patients: women with Charnley class C. Five moderate quality and five low quality studies further support the use of various risk assessment tools to predict outcomes and adverse events after THA. These include the EQ5D, SF-36, WOMAC, ASA classification, Charlson comorbidity index, and the Elixhauser score. Rolfson and Dahlberg, et al analyzed 6,158 Swedish Registry patients to determine that the EQ-5D anxiety/depression domain was highly predictive for pain relief and patient satisfaction after THA. Using the WOMAC and SF-36 Short Form, Gandhi, et al demonstrated that older age, year of followup, and greater comorbidity were negative prognostic indicators for THA function, and proposed that risk assessment data may be effectively utilized to set realistic patient expectations after THA. In another moderate quality study, Gordon and Frumento, et al studied over 134,000 patients from the Swedish registry. The Elixhauser comorbidity score was directly related to risk of re-operation within two years after THA. Martinez-Huedo, et al examined the effect of diabetes mellitus (DM) on 122,926 THA patients in the Spanish National Hospital Database. Immediate postoperative outcomes were worse among patients with DM, including increased length of hospital stay and in-hospital mortality. With respect to patients’ preoperative expectations, Judge, et al investigated the use of ASA status, WOMAC score, and EQ-5D, to show that risk assessment tools can be effectively utilized for informed patient-clinician decision-making.
