    Abstract

    Implant-based breast reconstruction has a higher infection risk than cosmetic augmentation, leading to routine prophylactic antibiotic use. We previously found extended prophylaxis reduced infections during the first-stage reconstruction with tissue expander/acellular dermal matrix placement. However, the most appropriate antibiotic class and duration of prophylaxis in the second-stage reconstruction remains unclear. This retrospective study aims to address this gap, focusing on antibiotic selection and duration during second-stage implant-based breast reconstruction.A single-center retrospective cohort study involved 359 patients undergoing second-stage breast reconstruction with tissue expander-implant exchange between January 2018 and January 2021. Chart reviews were performed to collect patient and surgical factors, antibiotic prophylaxis information, and postoperative outcomes. Multivariate logistic regression and likelihood ratio tests assessed associations between prophylaxis, covariates, and complications.Beyond a single perioperative dose of cefazolin, extended antibiotic prophylaxis did not significantly affect postoperative infection likelihood after second-stage breast reconstruction. Patients were grouped by antibiotic prophylaxis duration: 0 days (62 patients), 1 to 6 days (58 patients), and 7 or more days (239 patients). Extending antibiotic prophylaxis duration did not improve the prediction of 3-month postoperative infection rate (p = 0.581). A previous history of breast infection was a significant predictor for infection (p < 0.001).Extending antibiotics prophylaxis beyond a single preoperative dose of intravenous cefazolin does not reduce complication rates for patients undergoing second-stage breast reconstruction. Limiting prolonged prophylactic antibiotic use beyond the anesthetic period may reduce side effects (e.g., upset GI tract) and associated complications, including allergic reactions, Clostridium difficile colitis, and the emergence of new antibiotic-resistant pathogens.

  • Carpal tunnel syndrome diagnosis as a risk factor for falls. International orthopaedics Lakhlani, D., Shahoumian, T. A., Curtin, C. 2025

    Abstract

    PURPOSE: Subclinical peroneal neuropathy without overt foot drop has been linked to increased fall risk in adults, yet remains underreported due to subtle symptoms and lack of awareness. Patients with carpal tunnel syndrome (CTS) often experience other nerve entrapments, prompting this study to evaluate CTS (a proxy for peroneal nerve entrapment) as a significant predictor of time to first fall.METHODS: Data from the Merative MarketScan Research Databases (2007-2021) were used to identify adult patients using ICD-9/10 codes. Patients were stratified by CTS diagnosis and fall occurrences, with relevant comorbidities recorded. A survival analysis employing the Cox proportional hazards model assessed relationships between CTS, comorbidities, and future fall risk, accounting for changes in health status over time. Age was the time scale with CTS as a time-varying predictor. This approach isolated CTS-associated risk, while considering the natural increase in fall risk with age.RESULTS: Among 63,187,681 subjects (mean age=52.82 years±7.61), 1,411,695 had a diagnosis of CTS. Of those with CTS, 45,479 patients had a future fall. Univariate analysis showed significant associations between CTS and higher rates of arthritis and diabetes, while heart disease was less prevalent. CTS increased fall risk by 25% (HR 1.25, p<.005). Heart disease was associated with a 10% increase in fall risk (HR 1.10, p<.005), while arthritis and diabetes increased fall risk by 2% (both HR 1.02, p<.005). Kaplan-Meier curve illustrated a steeper decline in survival probability for the CTS group, indicating they experienced falls at younger ages and at a higher rate than those without CTS (chi = 4386.4, p<.001).CONCLUSION: Prior diagnosis of CTS is associated with an increased fall risk. Providers should screen CTS patients for fall risk and implement appropriate monitoring strategies. Further investigation on the role of peroneal nerve entrapment in this increased fall risk is warranted. This study identifies a treatable cause of falls, with potential to enhance patient safety and reduce fall-related morbidity.

  • Burn Center Verification and Safety-net Status: Are There Differences in Discharge to Inpatient Rehabilitation? Journal of burn care & research : official publication of the American Burn Association Lakhlani, D., Steeman, S., Stanton, E. W., Sheckter, C. 2024

    Abstract

    Discharge to acute rehabilitation following major burn injury is crucial for patient recovery and quality of life. However, barriers to acute rehabilitation, including race and payor type impede access. The effect of burn center organizational structure on discharge disparities remains unknown. This study aims to investigate associations between patient demographics, burn center factors, and discharge to acute rehabilitation on a population level. Using the California Healthcare Access and Information Database, 2009-2019, all inpatient encounters at verified and non-verified burn centers were extracted. The primary outcome was the proportion of patients discharged to acute rehabilitation. Key covariates included age, race, burn center safety net status, diagnosis related group, American Burn Association (ABA) verification status, and American College of Surgeons (ACS) Level 1 trauma center designation. Logistic regression and mixed-effects modeling were performed, with Bonferroni adjustment for multiple testing. Among 27,496 encounters, 0.8% (228) were discharged to inpatient rehabilitation. By race/ethnicity, the proportion admitted to inpatient rehabilitation was 0.9% for White, 0.6% for Black, 0.7% for Hispanic, and 1% for Asian. After adjusting for burn severity and age, notable predictors for discharge to inpatient rehabilitation included Medicare as payor (OR 0.30-0.88, p=0.015) compared to commercial insurance, trauma center status (OR 1.45-3.43, p<.001), ABA verification status (OR 1.16-2.74, p=0.008), and safety-net facility status (OR 1.09-1.97, p=0.013). Discharge to inpatient rehabilitation varies by race, payor status, and individual burn center. Verified and safety-net burn centers had more patients discharge to inpatient rehabilitation adjusted for burn severity and demographics.
