RESUMO
Background@#Many U.S. health care institutions have adopted compensation models based on work relative value units (wRVUs) to standardize payments and incentivize providers. A major determinant of payment and wRVU assignments is operative time. We sought to determine whether differences in estimated operative times between the Centers for Medicare & Medicaid Services (CMS) and the National Surgical Quality Improvement Program (NSQIP) contribute to payment and wRVU misvaluation for the most common shoulder/elbow procedures. @*Methods@#We collected data on wRVUs, payments, and operative times from CMS for 29 types of isolated arthroscopic and open shoulder/elbow procedures. Using regression analysis, we compared relationships between these variables, in addition to median operative times reported by NSQIP (2013–2016). We then determined the relative valuation of each procedure based on operative time. @*Results@#Seventy-nine percent of CMS operative time were longer than NSQIP time (R2 = 0.58), including, but not limited to, shoulder arthroplasty and arthroscopic shoulder surgery. The correlation between payments and operative times was stronger between CMS data (R2 = 0.61) than NSQIP data (R2 = 0.43). Similarly, the correlation between wRVUs and operative times was stronger when using CMS data (R2 = 0.87) than NSQIP data (R2 = 0.69). Nearly all arthroscopic shoulder procedures (aside from synovectomy, debridement, and decompression) were highly valued according to both datasets. Per NSQIP, compensation for revision total shoulder arthroplasty ($10.14/min; 0.26 wRVU/min) was higher than that for primary cases ($9.85, 0.23 wRVU/min) and nearly twice the CMS rate for revision cases ($5.84/min; 0.13 wRVU/min). @*Conclusions@#CMS may overestimate operative times compared to actual operative times as recorded by NSQIP. Shorter operative times may render certain procedures more highly valued than others. Case examples show that this can potentially affect patient care and incentivize higher compensating procedures per operative time when less-involved, shorter operations have similar patient-reported outcomes.
RESUMO
Background@#Racial and ethnic disparities in orthopedic surgery may be associated with worse perioperative complications. For patients with hip fractures, studies have shown that early surgery, typically within 24 to 48 hours of admission, may decrease postoperative morbidity and mortality. Our objective was to determine whether race is associated with longer time to surgery from hospital presentation and increased postoperative complications. @*Methods@#We queried the National Surgical Quality Improvement Program database from 2011 to 2017 for patients (> 65 years) with hip fractures who underwent surgical fixation. Patients were identified using Current Procedural Terminology codes (27235, 27236, 27244, and 27245). Delayed surgery was defined as time to surgery from hospital admission that was greater than 48 hours. Time to surgery was compared between races using analysis of variance. A multivariate logistic regression analysis adjusting for comorbidities, age, sex, and surgery was performed to determine the likelihood of delayed surgery and rate of postoperative complications. @*Results@#A total of 58,456 patients who underwent surgery for a hip fracture were included in this study. Seventy-two percent were female patients and the median age was 87 years. The median time to surgery across all patients was 24 hours. African Americans had the longest time to surgery (30.4 ± 27.6 hours) compared to Asians (26.5 ± 24.6 hours), whites (25.8 ± 23.4 hours), and other races (22.7 ± 22.0 hours) (p < 0.001). After adjusting for comorbidities, age, sex, and surgery, there was a 43% increase in the odds of delayed surgery among American Africans compared to whites (odds ratio, 1.43; 95% confidence interval, 1.29–1.58; p < 0.001). Despite higher odds of reintubation, pulmonary embolism, renal insufficiency or failure, and cardiac arrest in African Americans, mortality was significantly lower compared to white patients (4.41% vs. 6.02%, p < 0.001). Asian Americans had the lowest mortality rate (3.84%). @*Conclusions@#A significant disparity in time to surgery and perioperative complications was seen amongst different races with only African Americans having a longer time to surgery than whites. Further study is needed to determine the etiology of this disparity and highlights the need for targeted strategies to help at-risk patient populations.
RESUMO
BACKGROUND: Dupuytren disease is characterized by the development of palmar fibrous tissue that can lead to fixed flexion contracture (FFC) and contribute to functional loss of the involved digits. Our goal was to investigate rates of contracture resolution and recurrence in patients who underwent enzymatic fasciotomy for Dupuytren contracture consisting of collagenase clostridium histolyticum (CCH) injection followed by passive manipulation combined with splinting and home-based therapy. METHODS: We prospectively enrolled 34 patients (44 metacarpophalangeal [MCP] and 33 proximal interphalangeal [PIP] joints) treated by one orthopaedic hand surgeon between November 2010 and November 2014. On day 1, CCH was injected into a palpable fibrous cord of the involved fingers. The next day, the finger was passively extended to its maximal corrective position. FFC was measured for each joint before injection and immediately after manipulation. Patients were instructed to wear an extension splint at night and perform stretching exercises at home and were re-evaluated at 6 weeks, 4 months, 1 year, and 2 years. Resolution was defined as improvement of contracture to ≤ 5° of neutral. Recurrence was defined as an increase in FCC of ≥ 20° after treatment. RESULTS: Immediate contracture resolution occurred in 42 of 44 MCP joints (p < 0.001), improving from 50° to 1.5°, and in 14 of 33 PIP joints (p = 0.182), improving from 44° to 16°. Four joints had recurrence within 6 weeks. Of the 48 joints with minimum 4-month follow-up (mean, 26 months), 12 had recurrence at 2-year follow-up (MCP, 6; PIP, 6). At 2-year follow-up, MCP and PIP contractures measured 17° and 35.5°, respectively. Older age and multiple digit involvement were associated with higher recurrence rates. CONCLUSIONS: CCH offers a safe, nonoperative option to correct FCC in Dupuytren disease with greater success for MCP joints compared to PIP joints. There is a tendency of reoccurrence within 2 years of treatment. Further investigation is needed to determine optimal timing of repeat CCH injection to improve upon or extend the period of contracture resolution.
