Sex Disparities in Access to Surgical Care at a Single Institution in Malawi

Introduction: There is a paucity of data regarding sex-based disparities in surgical care delivery, particularly in low- and middle-income countries. This study sought to determine whether sex disparities are present among patients presenting with surgical conditions in Malawi. Hypothesis compared to men, fewer women present to Kamuzu Central Hospital (KCH) with peritonitis and have longer delays in presentation for definitive care. Methods: This study performs a retrospective analysis of prospectively collected data of all general surgery patients with peritonitis presenting to KCH in Lilongwe, Malawi, from September 2013 to April 2016. Multivariable linear and logistic regressions were used to assess the effect of sex on mortality, length of stay, operative intervention, complications, and time to presentation. Results: Of 462 patients presenting with general surgery conditions and peritonitis, 68.8% were men and 31.2% were women. After adjustments, women had significantly higher odds of non-operative management when compared to men (OR 2.17, 95%CI 1.30–3.62, P = 0.003), delays in presentation (adjusted mean difference 136 h, 95%CI 100–641, P = 0.05), delays to operation (adjusted mean difference 1.91 days, 95%CI 1.12–3.27, P = 0.02), and longer lengths of stay (adjusted mean difference 1.67 days, 95%CI 1.00–2.80, P = 0.05). There were no differences in complications or in-hospital or Emergency Department mortality. Conclusion: Sex disparities exist within the general surgery population at KCH in Lilongwe, Malawi. Fewer women present with surgical problems, and women experience delays in presentation, longer lengths of stay, and undergo fewer operations. Future studies to determine mortality in the community and driving factors of sex disparities will provide more insight

Outcomes and prognostic factors for women with breast cancer in Malawi

Background: Breast cancer incidence in sub-Saharan Africa (SSA) is increasing, and SSA has the highest age-standardized breast cancer mortality rate worldwide. However, high-quality breast cancer data are limited in SSA. Materials and Methods: We examined breast cancer patient and tumor characteristics among women in Lilongwe, Malawi and evaluated risk factor associations with patient outcomes. We consecutively enrolled 100 women ≥ 18 years with newly diagnosed, pathologically confirmed breast cancer into a prospective longitudinal cohort with systematically assessed demographic data, HIV status, and clinical characteristics. Tumor subtypes were further determined by immunohistochemistry, overall survival (OS) was estimated using Kaplan–Meier methods, and hazards ratios (HR) were calculated by Cox proportional hazard analyses. Results: Of the 100 participants, median age was 49 years, 19 were HIV-positive, and 75 presented with late stage (III/IV) disease. HER2-enriched and triple-negative/basal-like subtypes represented 17% and 25% tumors, respectively. One-year OS for the cohort was 74% (95% CI 62–83%). Multivariable analyses revealed mortality was associated with HIV (HR, 5.15; 95% CI 1.58–16.76; p = 0.006), stage IV disease (HR, 8.86; 95% CI 1.07–73.25; p = 0.043), and HER2-enriched (HR, 7.46; 95% CI 1.21–46.07; p = 0.031), and triple-negative subtypes (HR, 7.80; 95% CI 1.39–43.69; p = 0.020). Conclusion: Late stage presentation, HER2-enriched and triple-negative subtypes, and HIV coinfection were overrepresented in our cohort relative to resource-rich settings and were associated with mortality. These findings highlight robust opportunities for population- and patient-level interventions across the entire cascade of care to improve breast cancer outcomes in low-income countries in SSA
