RESUMO
BACKGROUND: Regional anesthesia has been associated with improved postoperative outcomes. Disparities in regional anesthesia utilization exist; however, no studies have examined utilization rates as a function of hospital region. METHODS: A national hospital database (Hospital Corporation of America {HCA}) was queried for patients aged 18 years or older that received selected surgical procedure codes between January 2016 and June 2021. Surgical procedures included were total knee arthroplasty (TKA), total shoulder arthroplasty (TSA), anterior cruciate ligament reconstruction (ACLR), carpal tunnel release, total abdominal hysterectomy (TAH), open reduction and internal fixation (ORIF) of the ankle, and arteriovenous (AV) fistula creation. Regional anesthesia was defined as any form of neuraxial and/or peripheral nerve blocks. Basic summary statistics were utilized to calculate the rates of regional anesthesia (RA), and chi-squared analyses were calculated to determine significant differences in the rate of RA utilization. RESULTS: There were 52,068 patients included in this study, of which 2,114 (4.1%) received RA. The greatest RA rates were for TSA (5.8%), TKA (4.5), and anterior cruciate ligament reconstruction (ACLR) (3.6%), whereas the lowest RA rate was for TAH (1.1%). For the TKA cohort, the Midwest had a significantly greater utilization rate than the South or West (10.9% vs. 4.8% or 3.1%, p<0.001). The Midwest also had the highest utilization rate in the ACLR cohort (8.1%, p<0.001), TAH cohort (16.7%, p<0.001), and AV fistula cohort (6.4%, p<0.001). For the carpal tunnel cohort, the West had the highest utilization rate (11.8% vs. 8.1%, 1.1%, 0%, p<0.001). The West region also had the highest utilization rate for the ankle ORIF (7.8%, p<0.001). No significant differences were found by region for TSA (p=0.31). CONCLUSION: Significant variations in RA utilization rates were found by region, with the West having the highest utilization for ankle ORIF and carpal tunnel, and the Midwest having the highest rate for TKA, ACLR, TAH, and AV fistula.
RESUMO
BACKGROUND: Regional anesthesia (RA) may improve patient-related outcomes, including decreased operative complications, shortened recovery times, and lower hospital readmission rates. More analyses are needed using a diverse set of databases to examine characteristics associated with the receipt of RA. METHODS: A national hospital database was queried for patients 18 years or older who underwent total shoulder arthroplasty (TSA), total knee arthroplasty (TKA), anterior cruciate ligament reconstruction (ACLR), carpal tunnel release, ankle open reduction, and internal fixation and arteriovenous fistula creation between January 2016 and June 2021. Regional techniques included neuraxial anesthesia and various upper and lower extremity peripheral nerve blocks to create a binary variable of RA receipt. Univariate statistics were used to compare characteristics associated based on RA receipt and multivariable regression identified factors associated with RA receipt. RESULTS: A total of 51 776 patients were included in the analysis, of which 2111 (4.1%) received RA. Factors associated with decreased odds of RA receipt included black race (vs white race; OR 0.73, 95% CI 0.62 to 0.86), other non-white race (vs white race; OR 0.71, 95% CI 0.61 to 0.86), American Society of Anesthesiologists (ASA) class (vs ASA 1; OR 0.85, 95% CI 0.79 to 0.93), and Medicaid insurance (vs private insurance; OR 0.65, 95% CI 0.51 to 0.82) (all p<0.05). When compared with TKA, ACLR (OR 0.67, 95% CI 0.53 to 0.84), ankle open reduction and internal fixation (OR 0.68, 95% CI 0.58 to 0.81), and carpal tunnel release (OR 0.68, 95% CI 0.59 to 0.78) demonstrated lower odds of RA receipt, whereas TSA (OR 1.31, 95% CI 1.08 to 1.58) demonstrated higher odds of RA receipt (all p<0.05). CONCLUSION: RA use varies with respect to race, insurance status, and type of surgery.
