Trends in the prevalence, incidence and surgical management of carpal tunnel syndrome between 1993 and 2013: an observational analysis of UK primary care records.

ABSTRACT: 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.

Project description:BackgroundCarpal tunnel syndrome is a common disorder in hand surgery practice. Both surgical and conservative interventions are utilized for the carpal tunnel syndrome. Although certain indications would specifically indicate the need for surgery, there is a spectrum of patients for whom either treatment option might be selected. The purpose of this systematic review was to compare the efficacy of surgical treatment of carpal tunnel syndrome with conservative treatment.MethodsWe included all controlled trials written in English, attempting to compare any surgical interventions with any conservative therapies. We searched Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2010), MEDLINE (1980 to June 2010), EMBASE (1980 to June 2010), PEDro (searched in June 2010), international guidelines, computer searches based on key words and reference lists of articles. Two reviewers performed study selection, assessment of methodological quality and data extraction independently of each other. Weighted mean differences and 95% confidence intervals for patient self-reported functional and symptom questionnaires were calculated. Relative risk (RR) and 95% confidence intervals for electrophysiological studies and complication were also calculated.ResultsWe assessed seven studies in this review including 5 RCTs and 2 controlled trials. The methodological quality of the trials ranged from moderate to high. The weighted mean difference demonstrated a larger treatment benefit for surgical intervention compared to non surgical intervention at six months for functional status 0.35( 95% CI 0.22, 0.47) and symptom severity 0.43 (95% CI 0.29, 0.57). There were no statistically significant difference between the intervention options at 3 months but there was a benefit in favor of surgery in terms of function and symptom relief at 12 months (0.35, 95% CI 0.15, 0.55 and 0.37, 95% CI 0.19 to 0.56). The RR for secondary outcomes of normal nerve conduction studies was 2.3 (95% CI 1.2, 4.4), while RR was 2.03 (95% CI 1.28 to 3.22) for complication, both favoring surgery.ConclusionBoth surgical and conservative interventions had treatment benefit in carpal tunnel syndrome. Surgical treatment has a superior benefit, in symptoms and function, at six and twelve months. Patient underwent surgical release were two times more likely to have normal nerve conduction studies but also had complication and side effects as well. Given the treatment differential and potential for adverse effects and that conservative interventions benefitted a substantial proportion of patients, current practice of a trial of conservative management with surgical release for severe or persistent symptoms is supported by evidence.

Project description:PURPOSE:Carpal tunnel release (CTR) is a common surgical procedure, representing a financial burden to the health care system. The purpose of this study was to test whether the choice of CTR technique (open carpal tunnel release [OCTR] vs endoscopic carpal tunnel release [ECTR]), surgical setting (operating room vs procedure room [PR]), and anesthetic type (local, monitored anesthesia care [MAC], Bier block, general) affected costs or payments. METHODS:Consecutive adult patients undergoing isolated unilateral CTR between July 2014, and October 2017, at a single academic medical center were identified. Patients undergoing ECTR converted to OCTR, revision surgery, or additional procedures were excluded. Using our institution's information technology value tools, we calculated total direct costs (TDCs), total combined payment (TCP), hospital payment, surgeon payment, and anesthesia payment for each surgical encounter. Cost data were normalized using each participant's surgical encounter cost divided by the average cost in the data set and compared across 8 groups (defined by surgery type, operation location, and anesthesia type). RESULTS:Of 479 included patients, the mean age was 55.3 ± 16.1 years, and 68% were female. Payer mix included commercial (45%), Medicare (37%), Medicaid (13%), workers' compensation (2%), self-pay (1%), and other (3%) insurance types. The TDC and TCP both differed significantly between each CTR group, and OCTR in the PR under local anesthesia was the lowest. The OCTR/local/operating room, OCTR/MAC/operating room, and ECTR/operating room, were associated with 6.3-fold, 11.0-fold, and 12.4-16.6-fold greater TDC than OCTR/local/PR, respectively. CONCLUSIONS:Performing OCTR under local anesthetic in the PR setting significantly minimizes direct surgical encounter costs relative to other surgical methods (ECTR), anesthetic methods (Bier block, MAC, general), and surgical settings (operating room). CLINICAL RELEVANCE:This study identifies modifiable factors that may lead to cost reductions for CTR surgery.
