Background: The Oxford Knee Score (OKS); Oxford Hip Score (OHS); Knee injury and Osteoarthritis Outcome Score, Joint Replacement (KOOS JR); and Hip disability and Osteoarthritis Outcome Score, Joint Replacement (HOOS JR) are well-validated and widely used short-form patient-reported outcome measures (PROMs) for assessing outcomes after total knee arthroplasty (TKA) and total hip arthroplasty (THA). We are not aware of the existence of any crosswalks to convert scores between these PROMs. We aimed to develop and validate crosswalks that will permit the comparison of scores between studies using different PROMs and the pooling of results for meta-analyses. Methods: We retrospectively analyzed scores from patients (486 in the knee cohort and 340 in the hip cohort) from the Syracuse Orthopedic Specialists Joint Registry who had completed the appropriate PROMs (OKS and KOOS JR in the knee cohort and OHS and HOOS JR in the hip cohort) as the standard of care before undergoing primary TKA or unicompartmental knee arthroplasty (UKA) between January 9, 2016, and June 19, 2017, or primary THA or hip resurfacing between November 29, 2010, and October 30, 2017, or when returning for postoperative care. Using the equipercentile equating method, we created 4 crosswalks: OKS to KOOS JR, KOOS JR to OKS, OHS to HOOS JR, and HOOS JR to OHS. To assess validity, Spearman coefficients were calculated using bootstrapping methods, and means for actual and crosswalk-derived scores were compared. Results: There were minimal differences between the means of the known and crosswalk-derived scores. As calculated with the use of bootstrapping methods, Spearman coefficients between the actual and derived scores were strong and positive for both knee arthroplasty crosswalks (0.888 to 0.889; 95% confidence interval [CI], 0.887 to 0.891) and hip arthroplasty crosswalks (0.916 to 0.918; 95% CI, 0.914 to 0.919). Conclusions: We successfully created 4 crosswalks that allow conversion of Oxford scores to KOOS and HOOS JR scores and vice versa. These crosswalks will allow harmonization of PROMs assessment regardless of which of the short forms are used, which may facilitate multicenter collaboration or allow sites to switch PROMs without loss of historic comparison data. Level of Evidence: Level III. See Instructions for Authors for a complete description of levels of evidence.
➤ Clinically important outcome values allow physicians to provide patients with more realistic expectations regarding their treatment that are based on their specific demographics.➤ Clinically important outcome values can vary for the same procedure or population depending on the method of calculation used, which raises the need for uniform ways to calculate and compare these values across populations and procedures.➤ A shift in approach from focusing solely on significant outcomes, or p values, to considering both clinically important and significant outcomes will allow clinicians to provide more efficient care, in line with recent trends toward a value-based health-care system.
Background. The effect of perioperative music listening has been proven to relieve preoperative anxiety and depression, while improving patient satisfaction. However, music listening has not been extensively studied in Singapore. Therefore, the primary aim of our study is to investigate the patient satisfaction towards perioperative music listening in the local setting. The secondary aim is to investigate the effect of perioperative music listening in reducing patient surgery-related anxiety and depression. Methods. After obtaining ethics board approval, we conducted a quasiexperimental study on a cohort of female patients who were undergoing elective minor gynaecological surgeries. Apple iPod Touch™ devices containing playlists of selected music genres and noise-cancelling earphones were given to patients to listen during the preoperative and postoperative periods. Hospital Anxiety and Depression Scale (HADS), EQ-5D-3L questionnaire, music listening preferences, and patient satisfaction surveys were administered. Wilcoxon signed-rank and McNemar’s tests for paired data were used for analysis. Results. 83 patients were analysed with 97.6% of patients in the preoperative period and 98.8% of patients in the postoperative period were satisfied with music listening. The median (IQR [range]) score for preintervention HADS anxiety was 7.0 (6.0 [0–17]), significantly higher than that in postintervention at 2.0 (4.0 [0–12]) (P<0.001). Similarly, there was a significant reduction in preintervention HADS depression as compared to postintervention (P<0.001). These results were corroborated by similar findings from the EQ-5D-3L questionnaire. Conclusion. Perioperative music listening improved patient satisfaction and can reduce patient anxiety and depression. We hope to further investigate on how wider implementation of perioperative music listening could improve patient care.
Background Although p values are standard for reporting statistical significance of patient-reported outcome measures (PROMs), the shift toward clinically important outcome values, including minimal clinically important difference (MCID) and substantial clinical benefit (SCB), necessitates re-evaluation of the current literature. Questions/Purposes We sought to answer two questions regarding studies on primary hip arthroscopy performed for the treatment of femoroacetabular impingement syndrome (FAIS). (1) Do such studies reporting statistical significance on common PROMs meet published MCID/SCB thresholds? (2) What proportion of such studies report both statistical and clinical significance? Methods We identified four papers published in two journals defining MCID/SCB values on the modified Harris Hip Score (mHHS), Hip Outcome Score–Activities of Daily Living (HOS-ADL), Hip Outcome Score-Sport (HOS-Sport), international Hip Outcome Tool (iHOT-33), and its short version (iHOT-12) for different groups of FAIS patients undergoing hip arthroscopy. We reviewed these two journals from the dates of publication to the present to identify papers reporting changes in post-operative PROMs. The difference in pre- and post-operative scores on each PROM was calculated and compared to MCID/SCB thresholds. Results Twelve studies were included. Ten studies (83%) evaluated mHHS (90% met MCID, 50% met SCB), seven (58%) evaluated HOS-ADL (100% met MCID/SCB) and HOS-Sport (100% met MCID, 57% met SCB), and one (8%) evaluated iHOT-33 (met MCID/SCB) and iHOT-12 (met MCID). Most studies met MCID and SCB at both 1- and 2-year timepoints. Of the studies evaluated, 50% reported clinical relevance. Conclusions Nearly all studies evaluated met MCID, while fewer met SCB. Only half discussed these clinical measures. It is proposed that all future studies report both statistical and clinical significance as standard best practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
