Workman's compensation as exclusion criteria in rotator cuff repair literature - are we inadvertently excluding race?

OBJECTIVE: Despite an equal willingness to participate in clinical trials, there is evidence that several minority populations are systematically under-represented in studies. One potential cause and frequently used exclusionary criterion in orthopedic trials is patients with active workman's compensation (WC) insurance claims. The purpose of this study is to determine demographic differences in patients undergoing arthroscopic rotator cuff repair with commercial and government insurance vs workers compensation claims. METHODS: This was a retrospective review of patients who underwent primary arthroscopic rotator cuff repair at a single institution in the northeastern United States from 2018 to 2019. Patients undergoing revision cases were excluded. Chart review was used to extract demographic data such as age, gender, insurance, and reported race. RESULTS: A total of 4553 patient records were reviewed and included. There were 742 WC patients and 3811 non-WC patients. Two hundred and forty-four patients did not report their race. Overall, WC patients differed from non-WC with respect to race (P < 0.001). One hundred and eleven (15.0%) of WC and 293 (7.7%) non-WC patients reported being 'Black' or 'African American' (P = 0.002). This compares to 368 (49.6%) WC and 2788 (73.2%) non-WC patients who reported 'White' (P < 0.001). About 16.8% of WC patients were identified as 'Hispanic or Latino,' compared to 5.2% of non-WC (P < 0.001). CONCLUSION: African American and Hispanic/Latino patients are over-represented in workman's compensation patient populations relative to non-workman's compensation. Conversely, white patients are over-represented in non-WC patient populations, which serve as the basis for the majority of clinical study populations. Excluding workman's compensation patients from clinical trials may lead to an underrepresentation of African American and Hispanic/Latino patient populations in orthopedic clinical trials. In doing so, the generalizability of the results of rotator cuff repair clinical outcomes research to all races and ethnicities may be compromised.

Combined Anterior Osteophytectomy and Cricopharyngeal Myotomy for Treatment of DISH-Associated Dysphagia.

STUDY DESIGN: Retrospective observational case series. OBJECTIVE: To assess the outcome of patients with diffuse idiopathic skeletal hyperostosis (DISH) with dysphagia who underwent cricopharyngeal myotomy (CPM) in conjunction with anterior osteophytectomy (OP). METHODS: This is a retrospective observational study of 9 patients that received combined intervention by neurosurgeons and otolaryngologists. Inclusion criteria for surgery consisted of patients who failed to respond to conservative treatments for dysphagia and had evidence of both upper esophageal dysfunction and osteophyte compression. We present the largest series in literature to date including patients undergoing combined OP and CPM. RESULTS: A total of 88.9% (8/9) of the patients who underwent OP and CPM showed improvement in their symptoms. Of the aforementioned group, 22.2% of these patients had complete resolution of their symptoms, 11.1% did not improve, and only 2 patients showed recurrence of their symptoms. None of the patients in whom surgery was performed required reoperation or suffered serious complication related to the surgical procedures. CONCLUSION: Based on the literature results, high rate of improvements in dysphagia, and low rate of complications, combined OP and CPM procedures may be beneficial to a carefully selected group of patients.

The fate of positive intraoperative cultures following conversion total hip arthroplasty.

INTRODUCTION: The objectives of this study are to report the rates of positive intraoperative cultures obtained during conversion total hip arthroplasty (THA) according to index surgery, and to describe the natural history of treatment for a consecutive series of patients with unexpected positive intraoperative cultures during conversion THA. METHODS: We reviewed all patients at 2 institutions undergoing conversion THA from prior open reduction and internal fixation (ORIF) of acetabular and hip fractures or hemiarthroplasty for displaced femoral neck fractures from 2011 to 2018. Intraoperative cultures were taken in 105 patients. Positive intraoperative cultures during conversion were recorded and managed with an infectious diseases consult. The outcomes including PJI at 90 days and 1 year follow-up were documented. RESULTS: Overall, 19 of 105 patients (18%) undergoing conversion THA had positive intraoperative cultures, with the highest rates in the hemiarthroplasty 7/16 (44%) and acetabular ORIF 9/48 (19%) groups. All 19 patients were initially treated conservatively: 8 received IV antibiotics, 10 received no additional therapy, and 1 received oral antibiotics. 4/9 acetabular fracture conversions developed PJI at 1 year, with 3 requiring multiple irrigation and debridement/polyethylene exchanges to control the infection while the 4th patient required 2-stage exchange. There were no 1-year PJI from any of the other index procedures after conversion. All 7 hemiarthroplasty patients with positive cultures were treated to resolution with 4-8 weeks IV antibiotics alone. CONCLUSIONS: Patients undergoing conversion THA from prior hip or acetabular fracture have a high rate of positive intraoperative cultures. As such, all patients undergoing conversion THA from prior hip or acetabular fracture fixation should undergo thorough diagnostic workup prior to surgery, and have intraoperative cultures obtained during surgery if infection remains suspicious. Further work should be performed to develop MSIS criteria for preoperative management of patients undergoing conversion THA.

Predictors of Prolonged Opioid Use After Lumbar Fusion and the Effects of Opioid Use on Patient-Reported Outcome Measures.

STUDY DESIGN: Retrospective case series. OBJECTIVE: To determine risk factors associated with prolonged opioid use after lumbar fusion and to elucidate the effect of opioid use on patient-reported outcome measures (PROMs) after surgery. METHODS: Patients who underwent 1-3 level lumbar decompression and fusion with at least one-year follow-up were identified. Opioid data were collected through the Pennsylvania Prescription Drug Monitoring Program. Preoperative "chronic use" was defined as consumption of >90 days in the one-year before surgery. Postoperative "prolonged use" was defined as a filled prescription 90-days after surgery. PROMs included the following: Short Form-12 Health Survey PCS-12 and MCS-12, ODI, and VAS-Back and Leg scores. Logistic regression was performed to determine independent predictors for prolonged opioid use. RESULTS: The final analysis included 260 patients. BMI >35 (OR: .44 [.20, .90], P = .03) and current smoking status (OR: 2.73 [1.14, 6.96], P = .03) significantly predicted postoperative opioid usage. Chronic opioid use before surgery was associated with greater improvements in MCS-12 (ß= 5.26 [1.01, 9.56], P = .02). Patients with prolonged opioid use self-reported worse VAS-Back (3.4 vs 2.1, P = .003) and VAS-Leg (2.6 vs 1.2, P = .03) scores after surgery. Prolonged opioid use was associated with decreased improvement in VAS-Leg over time (ß = .14 [.15, 1.85], P = .02). CONCLUSIONS: Current smoking status and lower BMI were significantly predictive of prolonged opioid use. Excess opioid use before and after surgery significantly affected PROMs after lumbar fusion.

Long-segment posterior cervical decompression and fusion: does caudal level affect revision rate?

OBJECTIVE: Posterior cervical decompression and fusion (PCDF) is a commonly performed procedure to address cervical myelopathy. A significant number of these patients require revision surgery for adjacent-segment disease (ASD) or pseudarthrosis. Currently, there is no consensus among spine surgeons on the inclusion of proximal thoracic spine instrumentation. This study investigates the benefits of thoracic extension in long-segment cervical fusions and the potential drawbacks. The authors compare outcomes in long-segment subaxial cervical fusion for degenerative cervical myelopathy with caudal vertebral levels of C6, C7, and T1. METHODS: A retrospective analysis identified 369 patients who underwent PCDF. Patients were grouped by caudal fusion level. Reoperation rates for ASD and pseudarthrosis, infection, and blood loss were examined. Data were analyzed with chi-square, 1-way ANOVA, and logistic regression. RESULTS: The total reoperation rate for symptomatic pseudarthrosis or ASD was 4.8%. Reoperation rates, although not significant, were lower in the C3-6 group (2.6%, vs 8.3% for C3-7 and 3.8% for C3-T1; p = 0.129). Similarly, rates of infection were lower in the shorter-segment fusion without achieving statistical significance (2.6% for C3-6, vs 5.6% for C3-7 and 5.5% for C3-T1; p = 0.573). The mean blood loss was documented as 104, 125, and 224 mL for groups 1, 2, and 3, respectively (p < 0.001). CONCLUSIONS: Given the lack of statistical difference in reoperation rates for long-segment cervical fusions ending at C6, C7, or T1, shorter fusions in high-risk surgical candidates or elderly patients may be performed without higher rates of reoperation.

Preoperative Opioid Use Increases the Cost of Care in Total Joint Arthroplasty.

INTRODUCTION: Predictors of financial costs related to total joint arthroplasty (TJA) have become increasingly important becuase payment methods have shifted from fee for service to bundled payments. The purpose of this study was to assess the relationship between preoperative opioid use and cost of care in primary TJA. METHODS: A retrospective study was conducted in Medicare patients who underwent elective unilateral primary total knee or hip arthroplasty between 2015 and 2018. Preoperative opioid usage, comorbidities, length of stay, and demographic information were obtained from chart review. The total episode-of-care (EOC) cost data was obtained from the Centers of Medicare and Medicaid Services based on Bundled Payments for Care Improvement Initiative Model 2, including index hospital and 90-day postacute care costs. Patients were grouped based on preoperative opioid usage. Costs were compared between groups, and multivariate linear regression analyses were performed to analyze whether preoperative opioid usage influenced the cost of TJA care. Analyses were risk-adjusted for patient risk factors, including comorbidities and demographics. RESULTS: A total of 3,211 patients were included in the study. Of the 3,211 TJAs, 569 of 3,211 patients (17.7%) used preoperative opioids, of which 242 (42.5%) only used tramadol. EOC costs were significantly higher for opioid and tramadol users than nonopioid users ($19,229 versus $19,403 versus $17,572, P < 0.001). Multivariate regression predicted that the use of preoperative opioids in TJA was associated with increased EOC costs by $789 for opioid users (95% confidence interval [CI] $559 to $1,019, P < 0.001) and $430 for tramadol users (95% CI $167 to $694, P = 0.001). Total postacute care costs were also increased by 70% for opioid users (95% CI 44% to 102%, P < 0.001) and 48% for tramadol users (95% CI 22% to 80%, P < 0.001). DISCUSSION: This study demonstrated that preoperative opioid usage was associated with higher cost of care in TJA. Limiting preoperative opioid use for pain management before TJA could contribute to cost savings within a bundled model.
