ABSTRACT
BACKGROUND: This study examined the complication rate of Wide Awake Local Anesthesia No Tourniquet (WALANT) technique in the clinic setting with field sterility at a single private practice. We hypothesized that WALANT is safe and effective with a low complication rate. METHODS: This retrospective chart review included 1228 patients who underwent in-office WALANT hand procedures at a single private practice between 2015 and 2022. Patients were divided into groups based on type of procedure: carpal tunnel release, A1 pulley release, first dorsal compartment release, extensor tendon repair, mass excision, foreign body removal, and needle aponeurotomy. Patient demographics and complications were recorded; statistical comparisons of cohort demographics and risk factors for complications were completed, and P < .05 was considered significant for all statistical comparisons. RESULTS: The overall complication rate for all procedures was 2.77% for 1228 patients including A1 pulley release (n = 962, 2.7%), mass excision (n = 137, 3.7%), extensor tendon repair (n = 23, 4.3%), and first dorsal compartment release (n = 22, 8.3%). Carpal tunnel release, foreign body removal, and needle aponeurotomy groups experienced no complications. No adverse events (e.g. vasovagal reactions, digital ischemia, local anesthetic toxicity, inadequate vasoconstriction) were observed in any group. Patients with known autoimmune disorders and those who were currently smoking had a statistically significant higher complication rate. CONCLUSIONS: Office-based WALANT procedures with field sterility are safe and effective for treating common hand maladies and have a similar complication profile when compared to historical controls from the standard operating room in an ambulatory center or hospital.
ABSTRACT
BACKGROUND: Access to total shoulder arthroplasty (TSA) may become a concern in the United States because of an aging and active population resulting in increased demand. As high-volume TSA surgeons have demonstrated superior outcomes, access to these surgeons is a matter of patient and public health policy interest. The release of the 2012 Medicare Provider Utilization and Payment Data Public Use File (MPUPD-PUF) in 2014 provided volume and reimbursement data for procedures performed by individual physicians participating in Medicare. This study analyzed surgeon prevalence, surgeon distribution, and factors associated with higher or lower surgeon prevalence in metropolitan areas. METHODS: The MPUPD-PUF was reviewed for the 2012 calendar year, and data were extracted for all physicians who performed a minimum of 11 TSA procedures for Medicare beneficiaries. Physicians in each major metropolitan area (population of >1 million) were grouped together. Average reimbursement, number of high-volume TSA surgeons, and number of total procedures were calculated per major metropolitan area. The presence of an American Shoulder and Elbow Surgeons (ASES) fellowship program and mean geographic reimbursement were analyzed for association with the number of high-volume TSA surgeons. RESULTS: The MPUPD-PUF included 774 surgeons across the United States who performed an annual minimum of 11 TSA procedures covered by Medicare, with a combined total of 19,505 TSA procedures. Of these surgeons, 45% practiced within major metropolitan areas with a population of >1 million. Surgeons who had completed an ASES fellowship had a higher volume of procedural claims (median, 26; range, 11 to 120) compared with other surgeons (median, 17; range, 11 to 163; p < 0.001). The distribution among major metropolitan areas was highly unequal, and more surgeons were present in cities with an ASES fellowship program. CONCLUSIONS: Access to high-volume shoulder arthroplasty surgeons by the Medicare population is lacking in multiple major metropolitan areas in the United States because of the uneven distribution of these surgeons. The method of analysis in this study allows for opportunities to target training programs as well as placement of physicians to ensure access to high-volume shoulder arthroplasty surgeons.
