RISK FACTORS FOR MORTALITY IN ADULT PATIENTS WITH COVID 19 IN NORTHEAST MEXICO
Abstract
Introduction
The pandemic, in terms of incidence, mortality and speed of expansion, is heterogeneous, even between regions of the same country, finding differences in its clinical presentation, severity and lethality; For this reason, the research aims to: know the risk factors associated with mortality in adult patients with COVID 19.
Material and methods
Retrospective cohort study included hospitalized patients, older than 18 years, diagnosed with Covid-19 through RT-PCR test. Data collected from the electronic file and analyzed to detect differences between survivors and non-survivors, using Student's t-test and Chi-square or Fisher's exact test. The relative risk was calculated with a 95% Confidence Interval (with statistical significance p <0.05.
Results
247 patients were studied. With a lethality of 50.20%. Arterial hypertension was the most frequent comorbidity. The oxygen supply with an invasive device was associated with a high risk of death. Tracheostomy is a high factor (p <0.001). With a statistical difference in favor of the early one. The mask and the nasal tips showed a protective effect (p <0.05). The most frequent symptoms were dyspnea, fever and cough without statistical difference. SatO2 at admission did show significance between both groups.
Conclusion
There is a difference between the risk factors in both groups. A peripheral SatO2 of <90% at admission and the determination of PNC and D-DIME warrant close monitoring to avoid severe complications.
