[Frequency of clinical characteristics and factors associated with mortality in patients hospitalized for COVID-19 in Puebla, Mexico].

Abstract

Background: Mexico has a very high mortality rate from COVID19, risk factors, clinical manifestations of our population are unknown.

Objective: To know risk factors for mortality from COVID19 in hospitalized patients of the Secretary of Health (SSA) Puebla, and clinical characteristics.

Material and methods: Case-control, observational, retrospective, cross-sectional study in COVID-19 patients. 2 groups: COVID-19 patients who died and those who did not die.

Results: 502  patients,  314  men  (62.5%  CI95%  58-66%),  188  women  (37.5%  CI95%  33-42%),  mean  age  54.14  +13.8,  interquartile  range  (IQR)  45-63, age interval 19 and 90 years, hospital stay (DEIH) 1-43 days, mean 9.8+7.8 days, median 8, IQR 4-13 days. Symptoms associated with mortality: dyspnea, chest pain, MR>1. Variables associated with mortality: age = or > 65 years, greater IHD, having > 2 comorbidities (OR 1.453), diabetes (OR 1.759), hypertension (OR 6.29) and chronic kidney failure (CRF) (OR 3.16) , (p<0.05). Ferritin >500ng/ml (OR 5.1799), DHL >400 IU/L (OR 3.313) and D-dimer >2000 m/ml (OR 2.868).

Conclusions: Age > or = 65 years, greater IHD, > 2 comorbidities, diabetes, hypertension or CRF, increased ferritin, D-dimer or DHL, are risk factors for mortality from COVID-19.
