Abstract
OBJECTIVES In this study, we evaluated the amount of public funds spent on the operative treatment of carpal tunnel syndrome (CTS) in Finland in 2011-2015. DESIGN A registry-based cost burden study. SETTING The data were collected in primary and secondary care in both private and public hospitals, covering the whole population of Finland. PARTICIPANTS We collected the total number of patients with new CTS diagnoses and the total number of patients undergoing surgery from the Care Register for Health Care, Finland's national register. INTERVENTIONS Open carpal tunnel release (OCTR). OUTCOME MEASURES We collected the costs of the OCTR procedure from diagnosis-related group prices. The Social Insurance Institution of Finland provided the total amount of euros reimbursed for sick leaves. We then combined the average amount of reimbursed sick leave with our estimated cost of the treatment chain to approximate the average cost per patient. RESULTS The average amount of public funds used for diagnosing and surgically treating new CTS in 2011-2015 in Finland, including reimbursements for sick leaves, was €2759 per patient in 2015 currency. The average direct procedure cost was €1020. We found no clear trend in total cost per patient, but the proportion of surgically treated patients rose from 63.14% to 73.09%. The total annual cost of these treatments was between €18 128 420 and €22 569 973. CONCLUSIONS The average amount of public funds used to surgically treat one patient with new CTS in 2011-2015 in Finland was €2759, making the total annual burden €20.7 million.

Abstract
PURPOSE Currently, electrodiagnostic testing, which comprises electromyogram (EMG) and nerve conduction studies (NCS), is the most commonly used method for confirming the clinical diagnosis of carpal tunnel syndrome (CTS). Electromyogram and NCS can be costly, can require multiple visits, may induce anxiety, and may be painful for patients. The purpose of this study was to determine whether replacing EMG/NCS with ultrasound (US), performed by the treating surgeon, to diagnose CTS decreases time to surgery and the number of office visits. METHODS We retrospectively reviewed a database that consisted of patients who presented to our department with numbness and/or tingling in the hand(s). We assessed the patients' histories for any subsequent carpal tunnel release, dates of diagnosis, dates of surgery, the number of CTS-related medical visits, and diagnostic methods employed. A fellowship-trained hand surgeon performed US examination, and the patients were referred for EMG/NCS testing. We collected data prior to surgery using the Boston Carpal Tunnel Questionnaire to evaluate symptom severity scale and functional status scale scores. We performed linear regression to assess differences in the time to surgery and the number of medical visits prior to carpal tunnel release. RESULTS Patients who had the diagnosis confirmed by the surgeon using US (n = 34) underwent surgical intervention 3-4 weeks earlier, with 1.8 fewer medical visits on average than the number of medical visits for those who had their diagnosis confirmed using EMG/NCS (n = 98). CONCLUSIONS If a confirmatory method for the diagnosis of CTS is required or desired by the treating surgeon, surgeon-conducted US might have an impact on the efficiency of care for patients with CTS.

Evaluation of Factors Affecting Return to Work Following Carpal Tunnel Release: A Statewide Cohort Study of Workers' Compensation Subjects. J Hand Surg Am 2022; 47:544-553.

Abstract
PURPOSE Most randomized trials comparing open carpal tunnel release (OCTR) to endoscopic carpal tunnel release (ECTR) are not specific to a working population and focus mainly on how surgical technique has an impact on outcomes. This study's primary goal was to evaluate factors affecting days out of work (DOOW) following carpal tunnel release (CTR) in a working population and to evaluate for differences in medical costs, indemnity payments, disability ratings, and opioid use between OCTR and ECTR with the intent of determining whether one or the other surgical method was a determining factor. METHODS Using the Ohio Bureau of Workers' Compensation claims database, individuals were identified who underwent unilateral isolated CTR between 1993 and 2018. We excluded those who were on total disability, who underwent additional surgery within 6 months of their index CTR, including contralateral or revision CTR, and those not working during the same month as their index CTR. Outcomes were evaluated at 6 months after surgery. Multivariable linear regression was performed to evaluate covariates associated with DOOW. RESULTS Of the 4596 included participants, 569 (12.4%) and 4027 (87.6%) underwent ECTR and OCTR, respectively. Mean DOOW were 58.4 for participants undergoing OCTR and 56.6 for those undergoing ECTR. Carpal tunnel release technique was not predictive of DOOW. Net medical costs were 20.7% higher for those undergoing ECTR. Multivariable linear regression demonstrated the following significant predictors of higher DOOW: preoperative opioid use, legal representation, labor-intensive occupation, increasing lag time from injury to filing of a worker's compensation claim, and female sex. Being married, higher income community, and working in the public sector were associated with fewer DOOW. CONCLUSIONS In a large statewide worker's compensation population, demographic, occupational, psychosocial, and litigatory factors have a significant impact on DOOW following CTR, whereas differences in surgical technique between ECTR and OCTR did not.

Abstract
PURPOSE Arthroscopic meniscectomy (APM) is the most common procedure in orthopedic surgery, despite increasing evidence questioning its benefit over conservative management for treatment of degenerative meniscal tears. The purpose of this study is to determine the epidemiology and trends of APM in Saskatchewan, a Canadian province, over a 20 year period. METHODS Physician billing codes were used to identify patients who underwent APM in Saskatchewan between January 1, 1998 and December 31, 2017. Records were obtained from eHealth Saskatchewan, a provincial health database. Data was analyzed for overall incidence and age-specific trends of APM. RESULTS A total of 35,099 APMs were performed during the study period. The population of Saskatchewan ranged from 992,314 to 1,150,782 (median 1,017,368) during this time interval, with 81 orthopedic surgeons performing APM. Overall incidence rate of APM did not change significantly over time. No decrease was observed in patients presumed to have degenerative tears (≥ 50 years). The number of meniscectomies in patients ≥ 50 years was significantly greater during the second decade of study compared to the first (OR 1.48, p < 0.01). Conversely, the increase in incidence rate among older patients was not statistically significant (R2 = 0.125, n.s.). CONCLUSION Overall incidence rate of APM in Saskatchewan has not decreased during the last 20 years. Furthermore, APM frequency increased over time for individuals ≥ 50 years. Several regional factors may have contributed to these findings, including the large proportion of Saskatchewan residents engaged in physically demanding work and barriers to accessing physiotherapy services. Given recent evidence disputing the benefit of APM over conservative measures, this study highlights the need for improved dissemination of evidence, as well as the importance of an individualized treatment plan to address patient-specific factors.

Abstract
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.

Abstract
Background: Despite studies demonstrating the effects of out-of-pocket costs on decision-making, the effect of societal cost information on patient decision-making is unknown. Given the considerable societal impact of cost of care for carpal tunnel syndrome (CTS), providing societal cost data to patients with CTS could affect decision-making and provide a strategy for reducing national health care costs. Therefore, we assessed the following hypotheses: (1) there is no difference in treatment choice (surgery vs no surgery) in a hypothetical case of mild CTS between patients randomized to receive societal cost information compared with those who did not receive this information; (2) there are no factors (eg, sex, experience with a previous diagnosis of CTS, or receiving societal cost information) independently associated with the choice for surgery; and (3) there is no difference in attitudes toward health care costs between patients choosing surgery and those who did not. Methods: In this randomized controlled trial using a hypothetical scenario, we prospectively enrolled 184 new and return patients with a nontraumatic upper extremity diagnosis. We recorded patient demographics, treatment choice in the hypothetical case of mild CTS, and their attitudes toward health care costs. Results: Treatment choice was not affected by receiving societal cost information. None of the demographic or illness factors assessed were independently associated with the choice for surgery. Patients declining surgery felt more strongly that doctors should consider their out-of-pocket costs when making recommendations. Conclusions: Providing societal cost information does not seem to affect decision-making and may not reduce the overall health care costs. For patients with CTS, health policy could nudge toward better resource utilization and finding the best care pathways for nonoperative and invasive treatments.

Abstract
PURPOSE To evaluate trends in Medicare physician reimbursements for 20 common hand procedures/surgeries from 2002 to 2018. METHODS The Physician Fee Schedule Look-up Tool was used to retrieve average reimbursement rates for 20 common hand surgeries/procedures from 2002 to 2018. All reimbursement data were adjusted for inflation to 2018 dollars. RESULTS After adjusting all data for inflation, the average reimbursement for all included procedures decreased by 20.9% from 2002 to 2018, with a compound annual growth rate of -3.25%. Reimbursement percentage decreases were the greatest prior to 2010 (18.4% decrease), followed by a relative stabilization (0.94% increase) from 2010 to 2014, after which physicians experienced a decrease of 3.9% in reimbursements between 2014 and 2018, following implementation of the Medicare Access and Children's Health Insurance Program Reauthorization Act in 2015. The most significant decreases in reimbursements over time were noted for primary tendon/muscle repair (-49.6%), wrist arthroscopy for triangular fibrocartilage repair/debridement (-44.0%), trigger finger release in facility (-40.1%), excision of extensor tendon sheath (-38.2%), ganglion cyst excision (-36.7%), wrist arthroscopy for diagnostic/synovial biopsy (-35.7%), wrist arthroscopy for drainage/infection/lavage (-35.1%), wrist arthrodesis (-30.6%), endoscopic carpal tunnel release (-27.2%), total wrist arthroplasty (-26.6%), carpometacarpal/basal joint arthroplasty (-25.1%), and open carpal tunnel release (-22.3%). The only procedures with a significant increase in reimbursement over time were trigger finger release in office (+4.2%), open reduction internal fixation distal radius fracture (+2.5%), and cubital tunnel release (+1.5%). CONCLUSIONS After adjusting for inflation, Medicare physician reimbursements for a major proportion of hand surgical procedures have decreased over time. CLINICAL RELEVANCE Health-policy makers need to understand the impact of decreasing reimbursements to develop policies of reimbursements that will not only ensure provider satisfaction but also maintain access to care for patients.

Abstract
Purpose The purpose of this study was to describe the impact of using a multidisciplinary hand clinic on (1) hand clinic waitlists for urgent operative pathologies and (2) the volume of urgent operative referrals seen by plastic surgery. Methods A retrospective data analysis of all new referrals to the Peter Lougheed Centre hand clinic in Calgary, Alberta, was performed. Data were collected from 6 months before and after the introduction of the multidisciplinary model (ie, between January 2017 and January 2018). Demographics for all new referrals were collected from the clinic database, including wait times, triage type, and volume of referrals triaged to each discipline. Results Prior to using a multidisciplinary model, 81% (n = 591) of new patient referrals were triaged directly to plastic surgery, 4% (n = 28) to physiotherapy, and 6% (n = 43) to minor surgery (N = 728). However, following the addition of physiatry to the clinic, 62% (n = 451) of new patient referrals were triaged directly to plastic surgery, 24% (n = 173) to physiatry, 2% (n = 17) to physiotherapy, and 4% (n = 31) to minor surgery (N = 730). Overall, the number of urgent operative referrals triaged to plastic surgery proportionally increased by 7%, from 67% to 74%. Mean wait times for urgent referrals to plastic surgery decreased by 1.7 ± 1.0 months (P = .09). Conclusion Applying a multidisciplinary model to a hand clinic can allow non-operative cases to be triaged directly to physiotherapy and physiatry, allowing plastic surgeons to manage a higher volume of urgent and operative referrals. Implementing a multidisciplinary hand clinic can, therefore, decrease waitlist volumes and shorten the time to assessment by a plastic surgeon. Type of Study Level II Prognostic Study.

Abstract
Health utility is a quantitative global measure of patients' health status. This retrospective cohort study aimed to compare health utilities of patients with mild to moderate versus severe carpal tunnel syndrome and determine inter-instrumental agreement. Health utilities of 29 patients with varying severity of carpal tunnel syndrome were measured indirectly by Short-Form Sixth Dimension and EuroQol 5D questionnaire and directly by Chained Standard Gamble and a visual analogue scale. Health utility was 0.69 for Short-Form Sixth Dimension, 0.78 for EuroQol 5D Questionnaire, 0.98 for Chained Standard Gamble, and 0.76 for the visual analogue scale. There was a significant inter-instrumental agreement between three of the instruments, but not the Chained Standard Gamble. The difference in health utilities between patients with mild or moderate versus severe carpal tunnel syndrome was significant only for the EuroQol 5D questionnaire. We conclude based on our results that there are no clear indications on how health utilities can be integrated into decision analysis models and economic evaluation regarding carpal tunnel syndrome of various severities.Level of evidence: IV.

Abstract
BACKGROUND Hyponatremia is the most common electrolyte disturbance amongst hospitalized patients. An overly rapid rate of correction of chronic hyponatremia is believed to increase the risk of poor clinical outcomes including osmotic demyelination syndrome (ODS). There is disagreement in the literature regarding the definition of hyponatremic overcorrection. METHODS We performed a systematic review of all English language studies to identify those that calculated sodium correction rate and classified patients' overcorrection status. We then identified all patients who presented to our hospital's emergency department between 2003 and 2015 with a corrected serum sodium ≤ 116 mmol/L. All methods from the systematic review for sodium correction rate calculation and overcorrection status were applied to this cohort. RESULTS We identified 24 studies citing 9 distinct sodium correction rate methods and 14 criteria for overcorrection. Six hundred twenty-four patients presenting with severe hyponatremia (median initial value 113 mMol) were identified. Depending on the method used, the median sodium correction rates in our cohort ranged from 0.271 to 1.13 mmol/L per hour. The proportion of patients classified with overcorrection with the different criteria varied almost 11-fold, ranging from 8.5 to 89.9%. CONCLUSION Published methods disagree regarding the calculation of sodium correction rates and the definition of hyponatremic overcorrection. This leads to wide variations in sodium correction rates and the prevalence of overcorrection in patient cohorts. Definitions based on ODS risk are needed.

Abstract
Value is defined as the worth, utility, or importance something holds. It can be derived from a variety of goods and services and is relative to a given industry or population. This article will discuss elements of plastic surgery that hold value as to how it pertains to the key players in a medical transaction. It will also discuss strategies for identifying and generating value. Roles of the different members in a plastic surgery transaction were analyzed, specifically the patient, the surgeon, and the facility. Different factors that generated value for all parties were identified throughout the literature. Factors identified that created value included the following: the surgeon's knowledge, experience, and decision-making ability; and technical skill/speed, restoration of life, restoration of form and function, restoration of psychological deficit, instant surgical results, convenience of access, outcomes, cost accounting, research, compassion, and bedside manner. Plastic surgeons can gear their practice to provide the system and their patients with services that hold value. We present several factors that can generate value for the patient, surgeon, and hospital system.
