Association of race and ethnicity with initial surgical hemodialysis access type in a safety net system.

OBJECTIVES: Prior studies have found lower arteriovenous fistula (AVF) creation rates in Black and Hispanic patients. Whether this is due to health care disparities or other differences is unclear. Our objective was to evaluate the racial/ethnic differences in initial surgical access type within a high-volume, safety net system with predominantly Black and Hispanic populations. METHODS: A retrospective review of initial hemodialysis (HD) access in consecutive cases between 2014 and 2019 was conducted from all five safety net hospitals in a health care system that primarily treats underserved patients. Patient data collected included race, ethnicity, sex, comorbidities, and initial arteriovenous (AV) access type (AV fistula [AVF] vs AV graft [AVG]). The rates of cephalic vein-based AVF (CAVF; radiocephalic, brachiocephalic) were compared with basilic and brachial vein AVF (BAVF), because the latter are performed as two stages. Bivariate and multivariate logistic regression models were adjusted for demographic and clinical variables to evaluate the relationship between race/ethnicity, surgical access type, and comorbid conditions. RESULTS: We included 1334 patients (74% Hispanic, 9% Black, 7% Asian, 2% White, 8% other) who underwent first-time surgical HD access creation. The majority were male (818 [63%]). Medical comorbidities were equal among groups, except for chronic obstructive pulmonary disease and stroke, which were higher in Black patients (P < .005 and P = .005, respectively). Overall, 1303 patients (98%) underwent AVF creation and 31 AVG creation (2%), with no difference between race/ethnicity in AVF vs AVG creation. Of the AVF cohort, 991 (76%) had a CAVF and 312 (24%) had a BAVF. Males were more likely than females to get a CAVF (65% vs 35%; P = .002). CONCLUSIONS: Within our safety net health system, where most patients are under-represented minorities, nearly all patients undergoing HD access had an AVF as their initial surgery with no difference in race/ethnicity. AVF type received differed by race, with Black patients twice as likely to undergo BAVF, which required two stages. Further studies are needed to identify the reasons for these differences.

Short Courses of Antibiotics Are Safe in Necrotizing Soft Tissue Infections.

INTRODUCTION: Necrotizing soft tissue infections (NSTIs) carry high morbidity and mortality. While early aggressive surgical debridement is well-accepted treatment for NSTIs, the optimum duration of adjunct antibiotic therapy is unclear. An increasing focus on safety and evidence-based antimicrobial stewardship suggests a value in addressing this knowledge gap. OBJECTIVE: To determine whether shorter antibiotic courses have similar outcomes compared to longer courses in patients with NSTI following adequate source control. POPULATION: 142 consecutive patients with surgically managed NSTI were identified on retrospective chart review between December 2014 and December 2018 at two academic medical centers. RESULTS: Patients were predominately male (74%) with a median age of 52 and similar baseline characteristics. The median number of debridements to definitive source control was 2 (IQR 1-3) with the short course group undergoing a greater number of debridements control 2.57 ± 1.8 vs 1.9 ± 1.2, (P = .01). Of 142 patients, 34.5% received a short course and the remaining 65.5% received a longer course of antibiotics. There was no significant difference in the incidence of bacteremia or wound culture positivity between groups. There was also no significant difference in in-hospital mortality, 8% vs 6% (P = .74), incidence of C. difficile infection, median length of stay, or 30-day readmission. CONCLUSION: Provided adequate surgical debridement, similar outcomes in morbidity and mortality suggest antibiotic courses of 7 days or less are equally safe compared to longer courses.
