Factores sociodemográficos, clínicos y asistenciales asociados al impacto de la Covid-19 en la capacidad funcional respiratoria post alta hospitalaria

Introduction: COVID-19 is an infectious disease that causes significant respiratory dysfunctions with long-term repercussions, lasting after medical discharge. In this study, association between socio-demographic, clinical and healthcare factors with the impact of COVID-19 on post-discharge respiratory functional capacity was determinated. Material and methods: observational study, analytical, cross-sectional study. The sample made up of 385 patients diagnosed with COVID-19. A data collection form was applied; the respiratory functional capacity was estimated. A bivariate analysis was performed using the fe chi square test and prevalence ratio, considering a significance of 95% (p<0.05). Results: of the 385 patients, 228 (59.2%) had normal respiratory capacity, and decreased in 157 (40.8%). Contemporary adults (55.84%) and males (67.80%) were mostly affected. Comorbidity (p= 0,292) and Co-Rads (p= 0,797) were not shown to be directly associated with respiratory involvement; contrary to RALE ≥ 3 in chest X-ray (p=0,000). The time in hospitalization, ICU and mechanical ventilation suggests to be related to the respiratory decrease. However, by PCR there was no statically significant evidence. But, clinical severe 3,029 [1,611 – 5,696] p= 0.001 and RALE ≥3 4,079 [2,248 – 7,401] p= 0,000, showed association. Conclusion: the degree of severity and RALE ≥ 3 in chest X-ray were identified as associated factors. It is suggest to carry out studies that confirm the findings of this research and propose a comprehensive rehabilitation protocol aimed at post-covid-19 patients that allows them to recover normal respiratory functional capacity.
