COVID-19 in-hospital mortality of a secondary care center of Mexico City in a marginated area during the first months of the Mexican epidemic
Abstract Introduction: Low socioeconomic conditions and hospital saturation have been associated with higher mortality rates in hospitalized patients with COVID-19. Mexico City has become the country’s highest death toll. Iztapalapa is the district with the highest population density and marginalization in Mexico City. Most of the information on COVID-19 in-hospital mortality in Mexico comes from intensive care units or tertiary hospitals without considering the level of income. Data regarding hospital mortality in care centers with low availability of intensive care beds has not been explored.Material and methods: A retrospective cohort study in consecutive patients with COVID-19 hospitalized managed outside the intensive care unit in a secondary care center in Mexico City from April 1st, 2020, to May 31st, 2020. Analysis was performed between subgroups with a p-value <0.05 considered statistically significant.Results: A total of 164 patients were recruited; the median age was 52.5 years (IQR 44 - 64.5), 68% were males, 48.7% were obese, and 59.7% had comorbidities. Among those patients, 67% required mechanical ventilation and 32.3% vasopressor support. In this population, 52 recovered (31.7%) and 112 died (68.3%). The main risk factors associated with death were male sex, age > 50 years, diabetes, severe pneumonia on admission, PORT / PSI > 91, SMART-COP > 5, SCAP score > 10, dyspnea on admission, fever during hospitalization [p <0.05] and the administration of intravenous antibiotics [RR 3.45, 95% CI 1.69-7.06, p <0.001].Conclusion: In this study, we found higher in-hospital mortality compared to previous reports. We suggest that the administration of intravenous antibiotics could impact patient survival for the risk of developing hospital-acquired infections.
