Risk factors for complications following immediate tissue expander based breast reconstruction in Taiwanese population.

BACKGROUND/PURPOSE: Breast cancer patients in Asia show considerable disparities from Caucasian patients, such as younger age of onset and lower rates of smoking, obesity, and diabetes. Findings of prior studies regarding risk factors associated with complications in tissue expander may not hold for Asian populations, since most of these studies involved Caucasian patients. In this study, we surveyed risk factors in the Taiwanese population, providing additional evidence about the important differences and discuss the implications for clinical practice. METHODS: Patients who underwent immediate, two-stage, tissue expander breast reconstruction from December 2008 to August 2014 in the National Taiwan University Hospital, Taipei, Taiwan were included. Follow-up observations of all patients were conducted until December 2014. Complications occurring during the tissue expander stage were evaluated. Multivariate regression modeling was used to identify risk factors for complications. RESULTS: A total of 246 consecutive, immediate, smooth round tissue expander placements were performed for breast reconstruction. The most common complication was skin necrosis (4.9%), followed by wound dehiscence (4.1%). In the multivariate model, body mass index (BMI) ≥ 24 kg/m2 was the only risk factor that reached statistical significance (odds ratio: 2.41, 95% confidence interval: 1.17-4.96). CONCLUSION: We provided evidence that racial disparities have an impact on the risk factors for complications associated with tissue expander breast reconstruction. BMI≥24 kg/m2 was the only risk factor significantly associated with complications. Clinically, BMI≥24 kg/m2, rather than the standard definition of obesity (BMI > 30 kg/m2), may be a more suitable cutoff point for risk in patients of Asian ethnicity.

Impact of Race on 30-Day Complication Rates After Elective Complex Spinal Fusion (≥5 Levels): A Single Institutional Study of 446 Patients.

OBJECTIVE: Racial disparities have been shown to affect surgical outcomes. However, the effect of race on complex spinal fusion outcomes remains understudied. The aim of this study is to determine if patient race affects 30-day complication rates after elective complex spinal fusion (≥5 levels). METHODS: The medical records of 490 adult patients with spinal deformity undergoing elective complex spinal fusion (≥5 levels) at a major academic institution from 2005 to 2015 were reviewed. We identified 52 black patients (11.7%) and 438 white patients (88.3%). Patient demographics, comorbidities, and intraoperative and 30-day postoperative complication and readmission rates were collected. The primary outcome investigated in this study was the rate of 30-day postoperative complications. RESULTS: Patient demographics and comorbidities were similar between both groups, including age, gender, and body mass index. Median (interquartile range) number of fusion levels and operative time were similar between the cohorts (black, 6.5 [5-9] vs. white, 7 [5-9]; P = 0.55; and black, 307.3 ± 120.2 minutes vs. white, 321.3 ± 135.3 minutes; P = 0.45, respectively). Both cohorts had similar postoperative complications and lengths of hospital stay (black, 7.2 ± 5.4 days vs. white: 6.5 ± 4.9; P = 0.37). There was no significant difference in 30-day readmission between the cohorts (black, 9.6% vs. white, 12.8%; P = 0.66). There were no observed differences in 30-day complication rates, including: pain (P = 0.74), urinary tract infection (P = 0.68), hardware failure (P = 0.36), wound dehiscence (P = 0.29), and drainage (P = 0.86). CONCLUSIONS: Our study suggests that there is no difference between races in 30-day complication and readmission rates after complex spinal surgery requiring ≥5 levels of fusion.
