RESUMO
BACKGROUND: Carpal tunnel syndrome (CTS) is associated with occupational high-force repetitive tasks and vibration. This project examines the relationship between CTS and work to: (1) identify jobs and industries with increased CTS risk; (2) explore whether there is a sex difference in the risk of CTS after controlling for occupation; and (3) determine whether any observed relationships persist after excluding Workers Compensation Board (WCB) accepted time-loss CTS claims. METHODS: We linked 95.5% of time-loss WCB claims from 2006 to 2019 to provincial administrative health data. The cohort included 143,001 unique person-occupation combinations. CTS cases were defined as at least two medical claims for (ICD-9 354) within a 12-month period or a surgical claim for CTS from 2 years before the WCB claim to 3 years after. WCB accepted CTS time-loss claims not identified by the medical claims were also included. RESULTS: A total of 4302 individuals (3.0%) met the CTS definition. Analysis revealed that the hazard ratios (HRs) of CTS vary considerably with occupation. Sex-based differences in CTS risks were observed, both in low- and high-risk occupations. In many occupations with increased HR, the HR remained elevated after excluding accepted time-loss WCB cases. CONCLUSIONS: The risk of developing CTS varied with occupation. Job titles with ergonomic risk factors had higher risks than those with lower exposures. This finding remained after eliminating time-loss compensated WCB cases, suggesting that all cases of CTS in high risk jobs are not identified in WCB statistics. Female workers in some job titles had excess CTS cases compared to male workers within the same job title.

BACKGROUND: Effective targeting of workplace upper extremity musculoskeletal disorder (MSD) prevention strategies requires the identification of demographic groups most at risk. Workers' compensation data provides an effective means of surveillance of MSDs at the population level. OBJECTIVE: The primary purpose of this study was to identify the effects of age and sex on rates of tendon injuries of the wrist and hand, carpal tunnel syndrome (CTS), epicondylitis, and soft tissue shoulder injuries in Ontario, Canada between 2000-2019 using workers' compensation data from the Association of Workers Compensation Boards of Canada (AWCBC). METHODS: Age and sex specific rates of lost-time injury claims from the four identified injury categories as well as "non-specific" upper extremity MSDs which did not fit into the four categories were calculated by standardizing injury claim totals with "at-risk" population estimates from the Canada Labour Force Survey. A multiple regression analysis was used to analyze the effects of age and sex on rates of specific injury claims. RESULTS: Statistically significant age and sex effects were identified for rates of claims from tendon injuries of the wrist and hand, CTS, and shoulder injuries, while only age effects were significant for epicondylitis. Between 2000-2019, rates of claims from the four injury categories studied and the magnitude of the age and sex effects declined substantially over time. CONCLUSION: Detailed surveillance of workplace ergonomic hazards in Ontario workplaces is needed to determine what is causing rates of upper extremity claims to decline.

BACKGROUND: Carpal tunnel release (CTR) is one of the most commonly performed procedures in hand surgery. Complications from surgery are a rare but significant patient dissatisfier. The purpose of this study was to determine whether insurance status is independently associated with complications after CTR. METHODS: We retrospectively identified all patients undergoing CTR between 2008 and 2018 using the Indiana Network for Patient Care, a state-wide health information exchange, and built a database that included patient demographics and comorbidities. Patients were followed for 90 days to determine whether a postoperative complication occurred. To minimize dropout, only patients with 1 year of encounters after surgery were included. RESULTS: Of the 26 151 patients who met inclusion criteria, 2662 (10.2%) had Medicare, 7027 (26.9%) had Medicaid, and 16 462 (62.9%) had commercial insurance. Compared with Medicare, Medicaid status (P < .001) and commercial insurance status (P < .001) were independently associated with postoperative CTR complications. The overall complication rate was 2.23%, with infection, wound breakdown, and complex regional pain syndrome being the most common complications. Younger age, alcohol use, diabetes mellitus, hypertension, and depression were also independently associated with complications. CONCLUSIONS: The incidence of complications after CTR is low. Insurance status, patient demographics, and medical comorbidities, however, should be evaluated preoperatively to appropriately risk stratify patients. Furthermore, surgeons can use these data to initiate preventive measures such as working to manage current comorbidities and lifestyle choices, and to optimize insurance coverage.

BACKGROUND: Carpal tunnel syndrome (CTS) is the most common nerve entrapment neuropathy caused by compression of median nerve at wrist as it passes through Osseo fibrous canal known as carpal tunnel. Epidemiological statistics shows one in every ten people develops the disease at any stage of life. CTS mostly affect females than males with mean age of 50. Clinical features are considered to be enough for establishing the diagnosis of carpal tunnel syndrome. However, nerve conduction studies give quantitative information regarding median nerve function therefore good at predicting outcome of intervention. Ultrasound being easily available, cost effective and real time is a promising modality for diagnosis and grading carpal tunnel syndrome. METHODS: This correlational study was conducted in collaboration of Neurology and Radiology Department of Pakistan Institute of Medical Sciences, Islamabad from January 2018 to January 2019. Total 50 patients with 85 wrists involved were included in the study. All patients with positive nerve conduction study were included. Patient with history of wrist trauma were not included. Detailed history and clinical features were recorded. All patients with positive result on nerve conduction studies underwent ultrasound examinations. Fifty control wrists were also included to establish the normal median nerve cross sectional area value in our study population. Results were recorded. Data was analyzed and appropriate statistical tests were applied by using SPSS v20. RESULTS: Mean cross sectional area of median nerve for controls was 6.34±1.23. Mean cross sectional area of median nerve for mild CTS was 8.05±1.72, moderate CTS was 11.15±2.32, severe was 17.49±4.93. Strong correlation was found between (r=0.76, p-value <0.0001) between increased cross-sectional area on Ultrasonography and severity of CTS on NCS. Other finding on Ultrasonography included flattening in 4 and fluid in 10 affected wrists. CONCLUSIONS: Increased cross-sectional area on Ultrasonography and severity of carpal tunnel syndrome on nerve conduction studies are very strongly correlated.

PURPOSE: Controversy exists regarding the closed treatment of distal radius fractures. Circumferential casting of acute distal radius fractures has been shown to be safe in children, however, little research has demonstrated its safety in adults. The purpose of this study was to assess the risk of complications associated with casting acute distal radius fractures in adult patients. METHODS: Patients with a distal radius fracture treated by a single hand surgeon at a level 1 trauma center were retrospectively reviewed over a 3-year period. Patients were evaluated in the emergency room and were provisionally immobilized either with short-arm fiberglass casts or with splints. Patients were followed for a minimum of 4 weeks. Complication rates associated with casting were recorded, including rates of compartment syndrome and acute carpal tunnel syndrome. RESULTS: Eighty-one patients were included in this study. A total of 30 patients met inclusion criteria for placement of a short arm cast in the Emergency Department. Mean patient age was 63.2 years. The majority of patients sustained their injuries from a ground level fall. A minority of patients had radiographic evidence of intra-articular extension or underwent a reduction prior to casting. There were no patients who developed compartment syndrome or acute carpal tunnel syndrome as a result from the casting. The majority of patients did not require a cast change for at least 4 weeks. None of our patients went on to surgery. CONCLUSION: There were no major complications associated with casting of acute, low energy distal radius fractures in this series of 30 adult patients. While further studies with larger numbers of patients are necessary to establish safety of casting, this study suggests that casting may be a safe and effective treatment for low-energy distal radius fractures in adult patients presenting with a normal neurovascular exam. TYPE OF STUDY/LEVEL OF EVIDENCE: Retrospective comparative study, Level III.

PURPOSE: Medical comorbidities have been associated with the development of carpal tunnel syndrome (CTS), severity at the time of presentation, and outcomes of carpal tunnel release (CTR). Socioeconomic factors have also been associated with worse function in patients with CTS at presentation and after surgery. However, the effects of economic well-being on the prevalence of medical comorbidities in patients with CTS have not been well-described. The objective of this study was to determine whether economic well-being is associated with medical comorbidities in a cohort of patients undergoing CTR. METHODS: Patients (n = 1,297) who underwent CTR at a single tertiary care referral center over a 5-year period from July 2008 to June 2013 were retrospectively identified. The exclusion criteria were acute trauma or infection, revision surgery, incomplete medical records, and neoplasm excision. Additionally, patients were excluded if they lacked documented confirmatory or normal electrodiagnostic study findings prior to CTR. Finally, this study comprised a cohort of 892 patients with electrodiagnostic study-confirmed CTS who underwent CTR. The economic well-being of patients was assessed using the Distressed Communities Index. The comorbidities of diabetes mellitus, chronic kidney disease, hypertension, hypothyroidism, cervical radiculopathy, tobacco use, and body mass index were assessed. Bivariate comparisons were used to determine the associations between the tiers of economic well-being and comorbidities. RESULTS: Lower economic well-being was associated with body mass index, diabetes mellitus, chronic kidney disease, and tobacco use in these patients. Although hypertension, hypothyroidism, and cervical radiculopathy were not associated with economic well-being, their comparisons were underpowered. CONCLUSIONS: Patients experiencing economic distress have a higher comorbidity burden, and as such, may be at an increased risk of complications or poorer outcomes. The association between economic well-being and comorbidities in this population suggests the need for a multidisciplinary care model that addresses both compressive neuropathy and the associated economic factors. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Background: Surgical carpal tunnel release is performed by either open carpal tunnel release (OCTR) or endoscopic carpal tunnel release (ECTR). The purpose of this study was to assess differences in intraoperative and postoperative complications, trends, and costs between OCTR and ECTR. Methods: State Ambulatory Surgery and Services Databases (SASD) files for California, Florida, and New Jersey were queried for patients who underwent OCTR and ECTR between 2000 and 2014. Patient demographics, comorbidities, intraoperative and postoperative complications, and cost were compared between OCTR and ECTR. The frequency of each procedure was used to formulate trends in OCTR and ECTR. Results: A total of 571 403 patients were included in this study. Sex was significantly different by a small percentage (OCTR = 64.8% female, ECTR = 65.4% female). A higher proportion of Hispanic patients underwent ECTR (P < .001). The patients who underwent OCTR had a greater comorbidity burden in terms of diabetes and rheumatoid arthritis (P < .001). None of the aforementioned complication rates were statistically significant between the 2 procedures. Endoscopic carpal tunnel release was significantly more costly by almost $2000. Open carpal tunnel release has remained stable over the years studied, whereas ECTR increased 3-fold. Conclusions: Our findings demonstrate no significant differences between OCTR and ECTR regarding intraoperative and postoperative complications and patient outcomes. Endoscopic carpal tunnel release was found to be significantly more costly.

BACKGROUND: Wild-type transthyretin (ATTRwt) amyloidosis is the most common systemic amyloidosis in Western countries and manifests mainly as progressive restrictive cardiomyopathy. OBJECTIVE: To study the prevalence of ATTR deposits in ligament tissue in patients undergoing surgery for lumbar spinal stenosis and to assess whether these deposits are associated with cardiac amyloidosis. MATERIALS AND METHODS: A total of 250 patients, aged 50-89 (57% women), none with known cardiovascular disease, were included. Ligaments were investigated microscopically for amyloid. ATTR type was determined by immunohistochemistry and fibril type by Western blot. The amount of amyloid was graded 0-4. All patients with grade 3-4 ATTR deposits were offered cardiac investigation including ECG, cardiac ultrasound, plasma NT-proBNP and cardiac magnetic resonance (CMR), including modern tissue characterization. RESULTS: Amyloid was identified in 221 of the samples (88.4%). ATTR appeared in 93 samples (37%) of whom 42 (17 women and 25 men) were graded 3-4; all had fibril type A (mixture of full-length TTR and fragmented TTR). Twenty-nine of 42 patients with grade 3-4 ATTR deposits accepted cardiovascular investigations; none of them had definite signs of cardiac amyloidosis, but five men had a history of carpal tunnel syndrome. CONCLUSIONS: The prevalence of ATTR deposits in ligamentum flavum in patients with lumbar spinal stenosis was high but not associated with manifest ATTR cardiac amyloidosis. However, the findings of fibril type A, the prevalence of previous carpal tunnel syndrome and ATTR amyloid in surrounding adipose and vascular tissue indicate that amyloid deposits in ligamentum flavum may be an early manifestation of systemic ATTR disease.

PURPOSE: To evaluate the null hypothesis that Medicaid patients receive carpal tunnel release (CTR) at the same time interval from diagnosis as do patients with Medicare Advantage or private insurance. METHODS: We conducted a retrospective review using a database containing claims records from 2007 to 2016. The cohort consisted of patient records with a diagnosis code of carpal tunnel syndrome (CTS) and a procedural code for CTR within 3 years of diagnosis. We stratified patients into 3 groups by insurance type (Medicaid managed care, Medicare Advantage, and private) for an analysis of the time from diagnosis until surgery and use of preoperative electrodiagnostic testing. RESULTS: Of all patients who received CTR within 3 years of diagnosis, Medicaid patients experienced longer intervals from CTS diagnosis to CTR compared with Medicare Advantage and privately insured patients (median, 99 days vs 65 and 62 days, respectively). The Medicaid cohort was significantly less likely to receive CTR within 1 year of diagnosis compared with the Medicare Advantage cohort (adjusted odds ratio [OR] = 0.54) or within 6 months of diagnosis compared with the privately insured cohort (adjusted OR = 0.61). Those in the Medicaid cohort were less likely to receive electromyography and nerve conduction studies within 9 months before surgery compared with their Medicare Advantage (adjusted OR = 0.43) and privately insured (adjusted OR = 0.41) counterparts. These effects were statistically significant after accounting for age, sex, region, and Charlson comorbidity index. CONCLUSIONS: Medicaid managed care patients experience longer times from diagnosis to surgery compared with Medicare Advantage or privately insured patients in this large administrative claims database. Similar variation exists in the use of electrodiagnostic testing based on insurance type. CLINICAL RELEVANCE: Medicaid patients may experience barriers to CTS care, such as delays from diagnosis to surgery and reduced use of electrodiagnostic testing.

Background: Carpal tunnel release (CTR) is the most common hand surgery operation performed in the United States. While serious complications are rare, they can be life-altering to patients. In some cases, patients will pursue malpractice claims against the surgeon. This study aimed to understand the patient, procedure, and surgeon factors involved in CTR malpractice litigation. Methods: The Westlaw legal database was queried for all recorded CTR malpractice cases resulting in jury verdicts and settlements. Only cases directly related to injury after CTR were included in this study. Cases were reviewed to determine plaintiff demographics, defendant training, liability, injury, outcomes, and monetary awards. Results: Ninety-two unique cases were identified. Plaintiffs were predominantly female (n = 65, 71%). Most surgeons were orthopedic-trained (n = 37, 52%). Only 27% of defendants (n = 19) were hand fellowship-trained. Only 19% of cases resulting in a monetary award were against surgeons who had hand fellowship training. The majority of cases (n = 61, 66%) were found in favor of the defendant. Monetary awards averaged $305 923 (range = $12 000-1 338 147), while settlements averaged $266 250. Alleged liability was most for surgeon negligence (n = 69, 75%) with a third of cases resulting in monetary awards. Median nerve injury was claimed in 41 cases (45%), with 17 (41%) resulting in monetary awards. Conclusion: Although CTR is generally safe and effective, some patients will experience complications. Median nerve injury was the most common reason for successful litigation in this study. Adequate training and experience in hand surgery may lower the risk of injuries resulting in successful malpractice suits.

PURPOSE: Social, mental, and physical health have a complex interrelationship with each influencing individuals' overall health experience. Social circumstances have been shown to influence symptom intensity and magnitude of disability for a variety of medical conditions. We tested the null hypothesis that social deprivation would not impact Patient-Reported Outcomes Measurement Information System (PROMIS) scores or objective health factors in patients presenting for treatment of carpal tunnel syndrome (CTS). METHODS: This cross-sectional study analyzed data from 367 patients who presented for evaluation of CTS to 1 of 6 hand surgeons at a tertiary academic center between August 1, 2016, and June 30, 2017. Patients completed PROMIS Physical Function-v1.2, Pain Interference-v1.1, Depression-v1.0, and Anxiety-v1.0 Computer Adaptive Tests. The Area Deprivation Index was used to quantify social deprivation. Medical record review determined duration of symptoms, tobacco and opioid use, and the Charlson Comorbidity Index (CCI) for each patient. Sample demographics, PROMIS scores, and objective health measures were compared in groups defined by national quartiles of social deprivation. RESULTS: Patients with CTS living in the most deprived quartile had worse mean scores across all 4 PROMIS domains compared with those living in the least deprived quartile. A higher proportion of individuals from the most deprived quartile had a heightened level of anxiety than those in the least deprived quartile (37.3% vs 12.6%). The mean CCI was higher in the most deprived quartile, as was the proportion of individuals using tobacco. There were no differences in opioid use or symptom duration between patients from each deprivation quartile. CONCLUSIONS: Social deprivation is associated with worse patient-reported health measures in patients with CTS. Compared with those from the least deprived areas, patients from the most deprived areas also have a greater comorbidity burden and higher rates of tobacco use at presentation to a hand surgeon. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Purpose: The purpose of this study was to report trends, complications, and costs associated with endoscopic carpal tunnel release (ECTR) and open carpal tunnel release (OCTR). Methods: Using Current Procedural Terminology (CPT) and International Classification of Diseases, Ninth Revision (ICD-9) codes, patients who had open versus endoscopic carpal tunnel release (CTR) were identified retrospectively in the PearlDiver database from both the Medicare and Humana (a private payer health insurance) populations from 2005 to 2014. These groups were then evaluated for postoperative complications, including wound infection within 90 days, wound dehiscence within 90 days, and intraoperative median nerve injury. We also used the data output for each group to compare the cost of the 2 procedure types. Data were analyzed via the Student t test. Statistical significance was set at P < .05. Results: A significantly lower percentage of patients in the endoscopic CTR group had a postoperative infection (5.21 vs 7.97 per 1000 patients per year, P < .001; 7.36 vs 11.23 per 1000 patients per year, P < .001) and wound dehiscence (1.58 vs 2.87 per 1000 patients per year, P < .001; 2.14 vs 3.73 per 1000 patients per year, P < .05) than open CTR group in the Medicare and Humana populations, respectively. Median nerve injury occurred 0.59/1000 ECTRs versus 1.69/1000 OCTRs (Medicare) and 1.96/1000 ECTRs versus 3.72/1000 OCTRs (Humana). Endoscopic CTR cost was more than open CTR for both the Medicare population ($1643 vs $1015 per procedure, P < .001) and Humana population ($1928 vs $1191 per procedure, P < .001). Conclusions: In both the Medicare and private insurance patient populations, endoscopic CTR is associated with fewer postoperative complications than open CTR, but is associated with greater expenses.

Carpal tunnel syndrome (CTS) occurs when the median nerve becomes compressed as it passes through the wrist within the carpal tunnel, resulting in pain, tingling, weakness, or numbness in the hand or the wrist. Occupational risk factors for CTS include engaging in work activities that require forceful, repetitive tasks, prolonged use of the hands or wrists in an awkward posture, or vibration (1). To assess trends and identify high-risk industries and occupations for CTS, the California Department of Public Health (CDPH) analyzed California workers' compensation claims for CTS by industry (2007-2014) and occupation (2014) and calculated rates per full-time equivalent (FTE) worker. During 2007-2014, a total of 139,336 CTS cases were reported (incidence = 6.3 cases per 10,000 FTE) in California workers; the rate among women (8.2) was 3.3 times higher than that among men (2.5). Industries with the highest rates of CTS were textile, fabric finishing, and coating mills (44.9), apparel accessories and other apparel manufacturing (43.1), and animal slaughtering and processing (39.8). Industries with high rates of CTS should consider implementing intervention measures, including ergonomic evaluations and development of tools and instruments that require less repetition and force and that correct awkward postures.

OBJECTIVE: Assess the effect of chronic comorbidities on hours and earnings recovery following a carpal tunnel syndrome (CTS) claim. METHODS: The hours and earnings profiles of Washington State workers' compensation claimants with CTS and controls, upper extremity fractures (UEF) claimants, were collected by linking to unemployment insurance data during 2007 to 2014. Chronic comorbidity status was determined from workers' compensation bills. RESULTS: More (43%) CTS claimants had diagnosed chronic comorbidities than UEF (24%). CTS claimants and claimants with multiple chronic comorbidities had significantly higher odds of not working post injury and poorer hours and earnings recovery compared with UEF claimants and those with no chronic comorbidities. CONCLUSIONS: This research suggests that chronic conditions should be considered as barriers to return to work among injured workers.

OBJECTIVES: To describe the prevalence, incidence and surgical management of carpal tunnel syndrome (CTS), between 1993 and 2013, as recorded in the Clinical Practice Research Datalink (CPRD). DESIGN: We completed a series of cross-sectional epidemiological analyses to observe trends over time. SETTING: Primary care data collected between 1993 and 2013, stored in the CPRD. POPULATION: Individuals aged ≥18 years were selected. Prevalent and incident episodes of CTS and episodes of surgical intervention were identified using a list of preidentified Read codes. ANALYSIS: We defined incident episodes as those with no preceding diagnostic code for CTS in the past 2 years of data. Episodes of surgery were expressed as a percentage of the prevalent population during the same calendar year. Joinpoint regression was used to determine significant changes in the underlying trend. RESULTS: The prevalence of CTS increased over the study period, with a particular incline between 2000 and 2004 (annual percentage change 7.81). The female-to-male prevalence ratio reduced over time from 2.74 in 1993 to 1.93 in 2013. The median age of females and males with CTS were noted to increase from 49 and 53 years, respectively in 1993 to 54 and 59 years, respectively in 2013. Incidence was also noted to increase over time. After an initial increase between 1993 and 2007, the percentage of prevalent patients with a coded surgical episode began to decrease after 2007 to 27.41% in 2013 (annual percentage change -1.7). CONCLUSION: This study has demonstrated that the prevalence and incidence of CTS increased over the study period between 1993 and 2013. Rates of surgery for CTS also increased over the study period; however after 2007, the per cent of patients receiving surgery showed a statistically significant decline back to the rate seen in 2004.

OBJECTIVE The epidemiology of carpal tunnel syndrome (CTS) has been extensively researched. However, data describing the economic burden of CTS is limited. The purpose of this study was to quantify the disease burden of CTS and determine the economic benefit of its surgical management. METHODS The authors utilized the PearlDiver database to identify the number of individuals with CTS in the Medicare patient population, and then utilized CPT codes to identify which individuals underwent surgical management. These data were used to calculate the total number of disability-adjusted life years (DALYs) associated with CTS. A human capital approach was employed and gross national income per capita was used to calculate the economic burden. RESULTS From 2005 to 2012 there were 1,500,603 individuals identified in the Medicare patient population with the diagnosis of CTS. Without conservative or surgical management, this results in 804,113 DALYs without age weighting and discounting, and 450,235 DALYs with age weighting and a discount rate of 3%. This amounts to between $21.8 and $39 billion in total economic burden, or $2.7-$4.8 billion per year. Surgical management of CTS has resulted in the aversion of 173,000-309,000 DALYs. This has yielded between $780 million and $1.6 billion in economic benefit per year. Endoscopic carpal tunnel release provided between $11,683 and $23,186 per patient at 100% success while open carpal tunnel release provided between $10,711 and $22,132 per patient at 100% success. The benefit-cost ratio at its most conservative is 2.7:1, yet could be as high as 6.9:1. CONCLUSIONS CTS is prevalent in the Medicare patient population, and is associated with a large amount of economic burden.

INTRODUCTION: We estimated the lifetime prevalence and incidence of carpal tunnel release (CTR) and identified risk factors for CTR. METHODS: The study population consisted of individuals aged ≥30 years living in Finland during 2000-2001 (N = 6,256) and was linked to the Finnish Hospital Discharge Register from 2000 to 2011. RESULTS: Lifetime prevalence of CTR was 3.1%, and incidence rate was 1.73 per 1,000 person-years. Female sex (adjusted hazard ratio [HR] = 1.8, 95% confidence interval [CI] 1.2-2.8), age of 40-49 years (HR = 2.5, CI 1.7-3.8 compared with other age groups), education (HR = 0.6, CI 0.4-0.9 for high level vs. low/medium level), obesity (HR = 1.7, CI 1.2-2.5 for body mass index ≥30 vs. < 30 kg/m2 ), and hand osteoarthritis (HR = 2.4, CI 1.4-3.9) were associated with incidence of CTR. DISCUSSION: CTR is a common surgical procedure, performed on 1.9% of men and 4.1% of women during their lifetimes. Obesity and hand osteoarthritis are associated with an increased risk of CTR.

PURPOSE: To establish the rate of postoperative infection after open carpal tunnel release (CTR) on a national level using an administrative database and define relevant patient-related risk factors associated with its occurrence. METHODS: The PearlDiver patient records database was used to query the 100% Medicare Standard Analytic Files retrospectively from 2005 to 2012 for patients undergoing open CTR using Current Procedural Terminology code 64721. Postoperative infection within 90 days of surgery was assessed using both International Classification of Diseases, Ninth Revision codes for diagnoses of postoperative infection or pyogenic arthritis of the wrist and Current Procedural Terminology codes for procedures for these indications, including either open or arthroscopic irrigation and debridement. We used a multivariable binomial logistic regression model that allows for assessment of the independent effect of a variable while controlling for remaining variables to evaluate which patient demographics and medical comorbidities were associated with an increased risk for postoperative infection. Adjusted odds ratios and 95% confidence intervals were calculated for each risk factor, with P < .05 considered statistically significant. RESULTS: A total of 454,987 patients met all inclusion and exclusion criteria. Of these patients, 1,466 developed a postoperative infection, corresponding to an infection rate of 0.32%. Independent positive risk factors for infection included younger age, male sex, obesity (body mass index of 30 to 40), morbid obesity (body mass index greater than 40), tobacco use, alcohol use, and numerous medical comorbidities including diabetes, inflammatory arthritis, peripheral vascular disease, chronic liver disease, chronic kidney disease, chronic lung disease, and depression. CONCLUSIONS: The current study reinforced conventional wisdom regarding the the overall low infection rate after CTR and revealed numerous patient-related risk factors that are independently associated with an increased risk of infection after open CTR in patients enrolled in Medicare. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

BACKGROUND AND OBJECTIVES: Carpal tunnel syndrome is a frequent cause of neuropathic pain of the upper limb. Surgery is often proposed in second-line treatment, leading to an expected decrease in analgesic drug consumption. The main objective of this study was to investigate the variations in analgesic drug prescriptions, with a special focus on constant or increasing prescription patterns, before and after surgery for carpal tunnel syndrome. METHODS: We designed a retrospective cohort study of French beneficiaries from the health insurance system in Midi-Pyrénées area. All patients undergoing carpel tunnel surgery during a specified period were identified and included. Definition of increased or constant prescription of analgesics was based on the comparison of the accumulated defined daily doses received by months and a difference between early preoperative (2 months before) and late postoperative period (2-12 months after surgery) superior to a -3.5 margin. We performed 4 multivariate logistic regression models to identify factors associated with increased or constant analgesic drug prescription patterns (for all analgesics, opioid, antineuropathic, nonopioid drugs). RESULTS: Among the 3665 patients included, 3255 (89%) received at least 1 analgesic drug during the late postoperative period (39% [n = 1426] for opioids and 15% [n = 563] for antineuropathic drugs). Prescription of analgesic, opioid, or antineuropathic drugs was maintained or increased in the late postoperative period in 11%, 5%, and 3% of the population, respectively. High levels of preoperative pain and female sex were associated with an increase in opioid use, whereas inpatient surgery (vs ambulatory surgery), high levels of preoperative pain, and psychiatric disorders were found to be associated with an increase in antineuropathic drug use. CONCLUSIONS: This study revealed that approximately 3% to 5% of patients undergoing carpal tunnel surgery had persistent and even increased use of opioid or antineuropathic drugs more than 2 months after surgery, in relation with possible chronic postoperative pain. Considering the incidence of carpal tunnel syndrome, the risks associated with persistent opioid use in this population should be further monitored.
