Symptoms During or Shortly After Isolated Carpal Tunnel Release and Problems Within 24 hours After Surgery.

ABSTRACT: This study used the National Survey of Ambulatory Surgery (NSAS) database to measure the incidence of and risk factors for symptoms in the ambulatory surgery center and problems within 24 h after isolated carpal tunnel release (CTR). The NSAS contained records on 400,000 adult patients with carpal tunnel syndrome who were treated with CTR in 2006, based on ICD-9 codes. The type of anesthesia used and factors associated with symptoms and problems were sought in bivariate and multivariable statistical analyses. The mean duration of the procedure was 16?±?8.8 min. Only 5 % were performed under local anesthesia without sedation, 45 % with IV sedation, 28 % regional anesthesia, and 19 % general anesthesia. Symptoms in the ambulatory surgery center or a problem within 24 h after discharge were recorded in 10 % of patients, all of them minor and transient, including difficulties with pain and its treatment. The strongest risk factors were male sex, age of 45 years and older, and participation of an anesthesiologist. Local anesthesia and regional anesthesia were associated with more perioperative symptoms and postoperative problems. Most CTR are performed with some sedation in the United States. CTR is a safe procedure: one in 10 patients will experience a minor issue in the perioperative or immediate postoperative period.

Project description:BackgroundCarpal tunnel syndrome is a common nerve compression disorder which affects hand sensation and function. Carpal tunnel release surgery (CTR) is frequently performed to alleviate these symptoms. For many CTR patients, surgery occurs during their working lifetime, but there is currently no evidence-based guidance to inform clinicians or patients when it might be safe to return to different types of work afterwards. The aim of this qualitative study was to explore the return to work experiences of patients who had recently undergone CTR.MethodsSemi-structured 1:1 interviews were conducted with a subgroup of participants recruited to a multi-centre prospective cohort study. Interviewees were purposely selected to represent a range of demographic, clinical and occupational characteristics. All had recently undergone CTR and had returned to work. Interviews were audio recorded, transcribed verbatim and analysed using the framework method. Participants were recruited until data saturation was achieved.ResultsFourteen participants were interviewed: 11 women (median age 49 years, range 27-61) and 3 men (age range 51-68 years). Three key themes were identified. Theme 1 centred on the level of functional disability experienced immediately after surgery. There was an expectation that CTR would be a 'minor' procedure, but this did not match the participants' experiences. Theme 2 explored the desire for validation for the time away from work, with participants recalling a need to justify their work absence to themselves as well as to their employers. Theme 3 focused on the participants' reflections of handing their return to work and function, with many reporting uncertainties about what constituted appropriate activity loads and durations. There was a desire for specific information relating to individual work roles.ConclusionIndividual return to work decision-making was largely influenced by the recommendations received. According to the views of participants, clinicians may be able to prepare patients better pre-operatively, especially with respect to function in the immediate post-operative period and by providing return to work guidance that can be tailored for individual work roles.

Project description:BACKGROUND:The American Society of Anesthesiologists (ASA) Choosing Wisely Top-5 list of activities to avoid includes "Don't obtain baseline laboratory studies in patients without significant systemic disease (ASA I or II) undergoing low-risk surgery - specifically complete blood count, basic or comprehensive metabolic panel, coagulation studies when blood loss (or fluid shifts) is/are expected to be minimal." Accordingly, we define low-value preoperative tests (LVTs) as those performed before minor surgery in patients without significant systemic disease. The objective of the current study was to examine the extent, variability, drivers, and costs of LVTs before carpal tunnel release (CTR) surgeries in the US Veterans Health Administration (VHA). METHODS:Using fiscal year (FY) 2015-2017 data derived from the VHA Corporate Data Warehouse (CDW), we determined the overall national and facility-level rates and associated costs of receiving any of 8 common LVTs in the 30 days before CTR in ASA physical status (PS) I-II patients. We also examined the patient, procedure, and facility factors associated with receiving ?1 LVT with mixed-effects logistic regression and the number of tests received with mixed-effects negative binomial regression. RESULTS:From FY15-17, 10,000 ASA class I-II patients received a CTR by 699 surgeons in 125 VHA facilities. Overall, 47.0% of patients had a CTR that was preceded by ?1 LVT, with substantial variability between facilities (range = 0%-100%; interquartile range = 36.3%), representing $339,717 in costs. Older age and female sex were associated with higher odds of receiving ?1 LVT. Local versus other modes of anesthesia were associated with lower odds of receiving ?1 LVT. Several facilities experienced large (>25%) increases or decreases from FY15 to FY17 in the proportion of patients receiving ?1 LVT. CONCLUSIONS:Counter to guidance from the ASA, we found that almost half of CTRs performed on ASA class I-II VHA patients were preceded by ?1 LVT. Although the total cost of these tests is relatively modest, CTR is just one of many low-risk procedures (eg, trigger finger release, cataract surgery) that may involve similar preoperative testing practices. These results will inform site selection for qualitative investigation of the drivers of low-value testing and the development of interventions to improve preoperative testing practice, especially in locations where rates of LVT are high.

Project description:BackgroundCarpal tunnel syndrome is the most common upper-extremity nerve compression syndrome. Over 500,000 carpal tunnel release (CTR) procedures are performed in the U.S. yearly. We estimated the cost-effectiveness of endoscopic CTR (ECTR) versus open CTR (OCTR) using data from published meta-analyses comparing outcomes for ECTR and OCTR.MethodsWe developed a Markov model to examine the cost-effectiveness of OCTR versus ECTR for patients undergoing unilateral CTR in an office setting under local anesthesia and in an operating-room (OR) setting under monitored anesthesia care. The main outcomes were costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). We modeled societal (modeled with a 50-year-old patient) and Medicare payer (modeled with a 65-year-old patient) perspectives, adopting a lifetime time horizon. We performed deterministic and probabilistic sensitivity analyses (PSAs).ResultsECTR resulted in 0.00141 additional QALY compared with OCTR. From a societal perspective, assuming 8.21 fewer days of work missed after ECTR than after OCTR, ECTR cost less across all procedure settings. The results are sensitive to the number of days of work missed following surgery. From a payer perspective, ECTR in the OR (ECTROR) cost $1,872 more than OCTR in the office (OCTRoffice), for an ICER of approximately $1,332,000/QALY. The ECTROR cost $654 more than the OCTROR, for an ICER of $464,000/QALY. The ECTRoffice cost $107 more than the OCTRoffice, for an ICER of $76,000/QALY. From a payer perspective, for a willingness-to-pay threshold of $100,000/QALY, OCTRoffice was preferred over ECTROR in 77% of the PSA iterations. From a societal perspective, ECTROR was preferred over OCTRoffice in 61% of the PSA iterations.ConclusionsFrom a societal perspective, ECTR is associated with lower costs as a result of an earlier return to work and leads to higher QALYs. Additional research on return to work is needed to confirm these findings on the basis of contemporary return-to-work practices. From a payer perspective, ECTR is more expensive and is cost-effective only if performed in an office setting under local anesthesia.Level of evidenceEconomic and Decision Analysis Level I.
