Factors associated with complex surgical wounds in breast and abdomen: a case-control observational study

Racial Disparities in Postoperative Breast Reconstruction Outcomes: A National Analysis

BACKGROUND

Studies have shown that Black patients are more likely to experience complications following breast reconstruction compared to other racial groups. Most of these studies have been conducted on patient populations focusing on either autologous or implant-based reconstruction without possible predictive indicators for complication disparities for all types of reconstruction procedures. The aim of this study is to elucidate disparities among patient demographics by identifying predictors of complications and postoperative outcomes among different racial/ethnic patients undergoing breast reconstruction utilizing multi-state, multi-institution, and national level data.

METHODS

Patients in the Optum Clinformatics Data Mart that underwent all billable forms of breast reconstruction were identified via CPT codes. Demographics, medical history, and postoperative outcome data were collected by querying relevant reports of CPT, ICD-9, and ICD-10 codes. Outcomes analysis was limited to the 90-day global postoperative period. A multivariable logistic-regression analysis was performed to ascertain the effects of age, patient reported ethnicity, coexisting conditions, and reconstruction type on the likelihood of any common postoperative complication occurring. Linearity of the continuous variables with respect to the logit of the dependent variable was confirmed. Odds ratios and corresponding 95% confidence intervals were calculated.

RESULTS

From over 86 million longitudinal patient records, our study population included 104,714 encounters for 57,468 patients who had undergone breast reconstruction between January 2003 and June 2019. Black race (relative to White), autologous reconstruction, hypertension, type II diabetes mellitus, and tobacco use were independent predictors of increased likelihood of complication. Specifically, the odds ratios for complication occurrence for Black, Hispanic, and Asian ethnicity (relative to White) were 1.09, 1.03, and 0.77, respectively. Black patients had an overall breast reconstruction complication rate of 20.4%, while the corresponding rate for White, Hispanic, and Asian patients were 17.0%, 17.9%, and 13.2%, respectively.

CONCLUSION

Our analysis of a national-level database shows that Black patients undergoing implant-based or autologous reconstruction have increased risk of complications, likely due to multifactorial components that play a role in the care of this patient population. While higher rates of comorbidities have been cited as a possible cause, providers must consider racial influences involving cultural context, historical mistrust in medicine, and physician/health institution factors that may drive this disparity of outcomes among our patients.

Breast Surgery: Management of Postoperative Complications Following Operations for Breast Cancer

Breast cancer surgery is associated with low rates of surgical morbidity. Postoperative complications related to breast surgery include seroma, infection, hematoma, mastectomy flap necrosis, wound dehiscence, persistent postsurgical pain, Mondor disease, fat necrosis, reduced tactile sensation after mastectomy, and venous thromboembolism. Postoperative complications related to axillary surgery include seroma, infection, lymphedema, nerve injury, and reduced shoulder/arm mobility. The overall rate of complication related to axilla surgery may be confounded by the type of breast surgery performed. The management of postoperative complications related to oncologic breast and axillary surgery independent of reconstruction is reviewed here.

Complicated Surgical Wounds and Associated Factors in Oncology Patients

The objective of this study was to identify the occurrence of complicated surgical wounds (CSWs) and to analyze the associated factors in hospitalized patients at an oncology institution. This was an epidemiological, observational, cross-sectional, descriptive, and correlational study conducted in the intensive care and hospitalization units forming part of a large cancer hospital. Sociodemographic and clinical data were collected from medical records and physical examinations of the skin. Associations between the dependent variable (presence of CSWs) and the independent variables were obtained by chi-square tests and odds ratio (OR) calculations with a 95% confidence interval. Logistic regression (LASSO) was used to verify the possible predictors of the outcome. The sample consisted of 341 patients, specifically individuals who are White (46.9%), married (53.4%), and men (58.1%) with an average age of 59.2 years. Complicated surgical wounds were present in 3.2% of patients, and the most frequent types of complications were dehiscence (40%), infection (26.7%), and fistula (20%) present in the abdominal (40%), cephalic (26.7%), and cervical (13.3%) regions. Senile purpura, diaper use, and infection were the clinical variables associated with the occurrence of CSWs (p = .044, p = .001, and p < .001, respectively). Based on the logistic regression, the presence of infection (p < .001; OR = 90.8; 95% CI [18.42, 538.79]) persisted as a predictor of the occurrence of CSWs. From these observations, recommendations regarding best practices for the prevention of CSWs are made, specifically for patients with cancer.
