Declining trends in Medicare physician reimbursements for shoulder surgery from 2002 to 2018.

BACKGROUND: As the current health care system evolves toward cost-containment and value-based approaches, evaluating trends in physician reimbursements will be critical for assessing and ensuring the financial stability of shoulder surgery as a subspecialty. METHODS: The Medicare Physician Fee Schedule Look-up Tool was used to retrieve average reimbursement rates for 39 shoulder surgical procedures (arthroscopy with or without repair, arthroplasty, acromioclavicular or clavicular open reduction-internal fixation, fixation for proximal humeral fracture and/or shoulder dislocation, open rotator cuff repair or tendon release and/or repair, and open shoulder stabilization) from 2002 to 2018. All reimbursement data were adjusted for inflation to 2018 dollars. RESULTS: After adjusting for inflation to 2018 dollars, average reimbursement for all included procedures decreased by 26.9% from 2002 to 2018. After stratifying the analysis by 3 distinct time groups, we observed that reimbursement decreases were the most significant prior to 2010. However, reimbursement rates still declined by an average of 2.9% from 2010 to 2014 and 7.2% from 2014 to 2018. Arthroscopic rotator cuff repair, capsulorrhaphy, and biceps tenodesis experienced smaller declines in reimbursement than their open-surgery counterparts. CONCLUSION: Medicare physician reimbursements for shoulder surgical procedures have decreased over time. Health care policy makers need to understand the impact of decreasing reimbursements to develop agreeable financial policies that will not only ensure provider satisfaction but also maintain access to care for patients.

Erosion of embolization coil into the renal collecting system: Retrograde fragmentation of stone and coil via thulium laser lithotripsy.

A 50-year-old female developed kidney stones on an eroded embolization coil 16 months after percutaneous nephrolithotomy (PCNL) related bleeding complications. Retrograde ureteroscopy and thulium laser lithotripsy was performed to fragment the exposed portion of the coil into clinically insignificant pieces. Thulium laser coil fragmentation remains a potential strategy to remove eroded coils and their associated kidney stones; however, recurrent stone formation on the coil stump may necessitate repeat intervention if this conservative approach is pursued over radical antegrade coil removal. This case highlights the importance of continued surveillance and multidisciplinary management in preventing and treating coil erosion after PCNL.

Risk factors for postoperative blood transfusion after shoulder arthroplasty.

Purpose: To identify the effect of surgical indication, patient factors, and perioperative characteristics on transfusion after shoulder arthroplasty (SA). Methods: Shoulder arthroplasties for osteoarthritis (OA) (N = 47), rotator cuff arthropathy (RCA) (N = 50), fracture (N = 76), revision (N = 66), and periprosthetic joint infection (PJI) (N = 35) performed at a single institution during a 6-year period were included. All other indications were excluded. Patient-based and surgical risk factors, including surgical indication, for postoperative allogeneic red blood cell transfusion were assessed with multivariate logistic regression analysis. Results: A total of 274 SAs were included; transfusions were performed in 2% (2/97) of primary SAs for OA or RCA. Increased transfusion rates occurred in PJI (23%, p = 0.0006) and fracture (18%, p = 0.0018) cases. The mean preoperative hemoglobin (Hgb) was 12.2 ± 2.2 with PJI, 12.0 ± 2.1 with fracture, and 13.3 ± 1.6 g/dL for all other SAs. Independent risk factors for transfusion included lower preoperative hemoglobin (p < 0.001), PJI indication (p = 0.008), and fracture indication (p = 0.02), with no difference for fracture greater or less than 4 weeks old (p = 0.53). Conclusion: Risk factors for allogeneic red blood cell transfusion after SA were low preoperative hemoglobin and procedures for PJI or fracture.Level of Evidence: Level III, retrospective case-control study.

Factors Associated With Elevated Inflammatory Markers Prior to Shoulder Arthroplasty.

Background: Preoperative erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) ranges for several shoulder arthroplasty indications are not well understood. Purpose: We sought to compare preoperative ESR and CRP values for a variety of shoulder arthroplasty indications and evaluate risk factors for elevated preoperative ESR and CRP values. Methods: We conducted a retrospective cohort study of shoulder arthroplasty cases performed at a single academic medical institution from 2013 to 2018. Preoperative ESR and CRP values for 235 shoulder arthroplasties with various indications were recorded. Independent risk factors for elevated values (CRP > 10.0 mg/L and ESR > 30.0 mm/h) were determined via multiple variable logistic regression. Results: Patients undergoing shoulder arthroplasty for osteoarthritis had an ESR (mean ± SD) of 22.6 ± 17.8, with 29.8% of patients elevated, and a CRP of 6.5 ± 6.4, with 25.5% of patients elevated. Arthroplasty for acute fracture and prosthetic joint infection (PJI) had higher preoperative ESR and CRP values. Multivariate analysis identified several predictors of elevated ESR, including infection, acute fracture, diabetes, and female sex. It also identified predictors of elevated CRP, including infection, acute fracture, and younger age. Conclusions: Preoperative ESR and CRP values may be elevated in 25% to 30% of patients undergoing primary shoulder arthroplasty. Arthroplasty for both acute fracture and PJI, along with several other patient factors, was associated with elevated preoperative ESR and CRP. Thus, routine collection of ESR and CRP preoperatively may not be of benefit, as elevated values are common. Further study is warranted.

The effect of patient factors on opioid use after anatomic and reverse shoulder arthroplasty.

BACKGROUND: Prolonged opioid use can lead to suboptimal outcomes after total shoulder arthroplasty (TSA), and thus, reduced consumption is desirable. Our primary aims were to determine if differences in total morphine equivalent doses existed owing to (1) age less than or greater than 65 years, (2) sex, and (3) TSA type - reverse or anatomic total shoulder arthroplasty. We also characterized potential risk factors for (1) visiting another provider for pain, (2) pain control 6 weeks postoperatively, and (3) needing an opioid refill. METHODS: A retrospective cohort study of 100 patients who underwent TSA (reverse total shoulder arthroplasty N 1 = 50; anatomic total shoulder arthroplasty N 2 = 50) between 1 July 2018 and 31 December 2018 was performed. Demographics, perioperative treatments, and postoperative opioid prescriptions were recorded. Primary hypotheses were evaluated with Wilcoxon-Mann-Whitney testing. Univariate and multivariate analyses assessed potential risk factors for the 3 outcomes of interest. Results were given in adjusted odds ratios (aORs), 95% confidence intervals (CIs), and P values. RESULTS: There was a difference (P = .009) in total morphine equivalent doses used (in 5-milligram oxycodone tablets) between patients who were younger than 65 years of age (median: 83 tablets, interquartile range: 62-140) and those who were older than 65 years of age (median: 65 tablets, interquartile range: 52-90). Unemployment (aOR = 4.68, CI: 1.5-14.2, P = .006) and age less than 65 years (aOR = 4.18, CI: 1.6-11.2, P = .004) were independent risk factors for inadequate pain control 6 weeks postoperatively. Two independent risk factors for needing an opiate prescription refill after discharge were unemployment (aOR = 4.56, CI: 1.5-13.8, P = .007) and preoperative opiate use (aOR = 3.95, CI: 1.4-11.0, P = .009). CONCLUSION: After TSA, morphine equivalent dose usage is higher for patients younger than 65 years of age, and several risk factors exist for requiring a refill and having inadequate pain control 6 weeks postoperatively. Prospective studies using these data to guide interventions may be beneficial.
