Cost Drivers in Carpal Tunnel Release Surgery: An Analysis of 8,717 Patients in New York State

As surgical management of carpal tunnel release (CTR) becomes ever more common, extensive research has emerged to optimize the contextualization of this procedure. In particular, CTR under the wide-awake, local-anesthesia, no-tourniquet (WALANT) technique has emerged as a cost-effective, safe, and straightforward option for the millions who undergo this procedure worldwide. CTR under WALANT is associated with considerable cost savings and workflow efficiencies; it can be safely and effectively executed in an outpatient clinic under field sterility with less use of resources and production of waste, and it has consistently demonstrated standard or better post-operative pain control and satisfaction among patients. In this review of the literature, we describe the current findings on CTR using the WALANT technique.

Optimization of Carpal Tunnel Syndrome Using WALANT Method

BACKGROUND It is unclear which carpal tunnel release (CTR) strategy (i.e., which combination of surgical technique and setting) is most cost-effective. A cost-effectiveness analysis was performed to compare (1) open CTR in the procedure room (OCTR/PR), (2) OCTR in the operating room (OCTR/OR), and (3) endoscopic CTR in the operating room (ECTR/OR). METHODS A decision analytic model was used to compare costs and health utilities between treatment strategies. Utility and probability parameters were identified from the literature. Medical costs were estimated with Medicare ambulatory surgical payment data. Indirect costs were related to days out of work due to surgical recovery and complications. The effectiveness outcome was quality-adjusted life years (QALYs). Probabilistic sensitivity analyses and one-way sensitivity analyses were performed. Cost-effectiveness was assessed from the societal and health-care system perspectives with use of a willingness-to-pay threshold of $100,000/QALY. RESULTS In the base-case analysis, OCTR/PR was more cost-effective than OCTR/OR and ECTR/OR from the societal perspective. The mean total costs and QALYs per patient were $29,738 ± $4,098 and 0.88 ± 0.08 for OCTR/PR, $30,002 ± $4,098 and 0.88 ± 0.08 for OCTR/OR, and $41,311 ± $4,833 and 0.87 ± 0.08 for ECTR/OR. OCTR/PR was also the most cost-effective strategy from the health-care system perspective. These findings were robust in the probabilistic sensitivity analyses: OCTR/PR was the dominant strategy (greater QALYs at a lower cost) in 55% and 61% of iterations from societal and health-care system perspectives, respectively. One-way sensitivity analysis demonstrated that OCTR/PR and OCTR/OR remained more cost-effective than ECTR/OR from a societal perspective under the following conditions: $0 surgical cost of ECTR, 0% revision rate following ECTR, equalization of the return-to-work rate between OCTR and ECTR, or 0 days out of work following ECTR. OCTR/OR became more cost-effective than OCTR/PR with the median nerve injury rate tripling and doubling from societal and health-care system perspectives, respectively, or if surgical direct costs in the PR exceeded those in the OR. CONCLUSIONS Compared with OCTR/OR and ECTR/OR, OCTR/PR minimizes costs to the health-care system and society while providing favorable outcomes.

Optimizing Costs and Outcomes for Carpal Tunnel Release Surgery: A Cost-Effectiveness Analysis from Societal and Health-Care System Perspectives.

Background Septic arthritis (SA) of the knee following anterior cruciate ligament reconstruction (ACLR) is considered a catastrophic complication in terms of reduced or loss function of the involved joint. The aims of this study were to gauge the incidence, risk factors, and causative organisms of SA after ACLR. Methods We conducted a retrospective review of 836 patients who underwent primary ACLR at our institution from October 2018 to September 2021. Patients’ demographics, onset of presentation, clinical symptoms, laboratory findings, and management details were obtained from patients’ electronic medical records. Results Out of the 836 primary ACLRs, 12 were complicated with SA (1.43%). Independent risk factors associated with SA included age (OR; 11.12, 95% CI; 1.3–94.97), obesity (OR; 8.51, 95% CI; 1.02–71.13), and diabetes mellitus (OR; 12.58, 95% CI; 2.39–66.3). Staphylococcus aureus was the most frequent culprit organism (66.7%), followed by Streptococcus species (25%), and Pseudomonas aeruginosa (8.3%). No fungal, mycobacterial, or polymicrobial growth were recovered from synovial fluid cultures. All of the infected cases underwent arthroscopic joint lavage and debridement in the operating room followed by intravenous antibiotics. Graft removal was not done in any of the involved patients, with eradication of infection in all cases. Conclusion SA after ACLR is uncommon, with S. aureus identified in about two-thirds of the patients. Prompt diagnosis and treatment are crucial to avoid graft loss and arthritis-associated joint damage. Orthopedic surgeons should consider rigorous implementation of infection control strategies to minimize the incidence of this devastating morbidity.

Septic Arthritis Complicating Arthroscopic Anterior Cruciate Ligament Reconstruction: An Experience from a Tertiary-Care Hospital

Background The effectiveness of open carpal tunnel release (OCTR) in treating carpal tunnel syndrome (CTS) is well known. However, the role of ancillary external neurolysis of the median nerve is not well-documented. The Boston carpal tunnel questionnaire (BCTQ) is a commonly used disease-specific outcome instrument for CTS, which is validated across major languages of the world. No such validated Hindi version of BCTQ exists. Objectives To analyze and compare the long-term outcome in patients who underwent OCTR alone and OCTR with external neurolysis of the median nerve, using BCTQ–Hindi version, while checking its validity. Materials and Methods A retrospective, cross-sectional study was conducted at a tertiary care institute. The BCTQ was translated into Hindi language by a language expert. Eighty-four consecutive patients who underwent either unilateral/bilateral OCTR, with or without external neurolysis of the median nerve, between 2009 and 2019 were included in the study. Outcome analysis was done using BCTQ–Hindi version and patient satisfaction scoring. BCTQ–Hindi version was examined for statistical validity. Subgroup analysis of the outcome based on surgical technique (OCTR vs. OCTR with external neurolysis) used was carried out. Results Response rate was 80.9%. Total hands evaluated were 108. BCTQ–Hindi version showed statistical validity. Overall symptom severity score (SSS) and functional severity score (FSS) were 1.14 ± 0.4 and 1.12 ± 0.35, respectively. Subgroup analysis of outcome revealed statistically significant results in favor of OCTR with external neurolysis of the median nerve. Conclusions BCTQ–Hindi version is statistically validated. OCTR with external neurolysis of the median nerve is a promising avenue in surgical management of CTS. Further prospective studies are warranted.

Analysis of the Long-Term Outcome in Open Carpal Tunnel Release Surgeries with and without External Neurolysis of Median Nerve, Using Boston Carpal Tunnel Questionnaire (BCTQ)-Hindi Version.

Purpose The goal of this study was to determine whether the type of anesthesia (monitored anesthesia care [MAC] vs wide-awake local anesthesia no tourniquet technique [WALANT]) or the surgical technique (mini-open vs endoscopic) would affect patient satisfaction with postoperative pain control, postoperative pain, or opioid use after carpal tunnel release (CTR). The hypothesis was that endoscopic and open CTR surgery would have the same patient satisfaction with postoperative pain control, postoperative pain, and opioid use, but WALANT surgery would have higher patient satisfaction with postoperative pain control, postoperative pain, and opioid use than MAC. Methods This prospective study examined all patients undergoing carpal tunnel surgery by 4 hand surgeons at our institution. Two surgeons perform primarily 1-incision endoscopic CTR and the other 2 perform mini-open CTR. Two surgeons perform all procedures under WALANT; the other 2 employ MAC with a local anesthetic. Postsurgical questionnaires were completed at the 2-week postoperative visit. Patients reported remaining pills, average pain, highest pain, lowest pain, and overall satisfaction with postoperative pain control. Results A total of 93 patients underwent CTR by the 4 participating hand surgeons. Of these, 43 underwent open CTR and 50 underwent endoscopic CTR. Sixty-two were performed under MAC and 31 with WALANT. With regard to anesthesia type, overall there was 5.5 mean morphine equivalents (MME) less prescribed and an average of 3.6 MME more remaining on the first postoperative visit with WALANT compared with MAC. Patient satisfaction with postoperative pain control was an average score of 7.9 for MAC and 7.4 for WALANT. With regard to surgical technique, overall, there was 15.2 MME less prescribed and an average of 1.03 MME more remaining on the first postoperative visit with endoscopic CTR compared with open CTR. Patient satisfaction with postoperative pain control between endoscopic and open release demonstrated an average score of 7.1 and 8.0, respectively. Conclusions This study demonstrates minimal differences in opioid pain medication use, patient satisfaction with postoperative pain control, and pain scores in a comparison of surgical technique as well as anesthesia type. Type of study/level of evidence Therapeutic IV.

Prospective Evaluation of Surgical and Anesthetic Technique of Carpal Tunnel Release in an Orthopedic Practice.

Introduction/background Given the uncommon nature of the multi-ligament injured knee, a better understanding of its outcomes may be achieved by contemporary evaluation of a national administrative database. We aim to identify risk factors for 90-day major complications, 90-day readmissions, and subsequent knee surgery after a multi-ligament knee reconstruction. Methods The Humana Claims Database was queried for all patients undergoing a multi-ligament knee reconstruction procedure from 2007 to 2016 using International Classification of Diseases (ICD)-9 procedure codes and Current Procedural Terminology (CPT) codes. Outcomes of interest included Center of Medicaid and Medicare Services (CMS)- reportable 90-day complications, 90-day readmission and subsequent ligament reconstruction or total knee arthroplasty. Predictive factors studied included demographics (ie. age, sex, tobacco use) comorbidity burden and operative factors (ie. surgical setting, diagnosis of knee dislocation, concomitant meniscal repair or meniscectomy). Results 588 multi-ligament knee reconstruction procedures were identified. The 90-day readmission rate 8.3%. The rate of subsequent ligament surgery was 7.1%. On multivariate regression analysis, a diagnosis of knee dislocation was associated with a four times greater likelihood of readmission and a two and a half greater likelihood of subsequent ligament surgery. Concomitant meniscectomy was associated with higher likelihood of subsequent total knee arthroplasty (9.1, 1.4–67.0) and outpatient setting of surgery compared to inpatient hospital setting was associated with reduced likelihood of readmission. Conclusion While uncommon, the patient population undergoing multi-ligament knee surgery is relatively diverse. Understanding common factors predisposing this population to adverse events following surgery may assist in improved outcomes.

Background Bilateral endoscopic carpal tunnel release is a modality offered for the treatment of the median nerve compression neuropathy. This retrospective study compares outcomes for patients undergoing open carpal tunnel release versus bilateral endoscopic carpal tunnel release. We hypothesized that there is no significant difference in postoperative complication rates between unilateral open and bilateral endoscopic carpal tunnel release surgery. Methods The authors identified all patients who underwent open carpal tunnel release, unilateral endoscopic carpal tunnel release and bilateral endoscopic carpal tunnel release at a university hospital from 2012 to 2014. Cases were identified using CPT billing codes and the data was assessed using an analysis of variance (ANOVA). All endoscopic carpal tunnel releases were done by the same surgeon (AP), and greater than 90% of open procedures were done by a different same surgeon (DF). Results The total combined complication rate was 24.7% with no significant difference (p > .05) between techniques. There were no major complications necessitating a return to the operating room. Variables that had a statistically significant difference between groups (p  Conclusions The study demonstrates equivocal complication profiles and decreased cost associated with bilateral endoscopic tunnel release as compared to sequential open carpal tunnel release. Endoscopic bilateral carpal tunnel release for patients with bilateral carpal tunnel syndrome offers a safe and effective alternative to open carpal tunnel release.
