MALNUTRITION PROLONGS THE HOSPITALIZATION OF PATIENTS WITH COVID-19 INFECTION: A CLINICAL EPIDEMIOLOGICAL ANALYSIS

Objectives: During the 2019 coronavirus disease (COVID-19) outbreak, malnutrition may contribute to COVID-19 adverse outcomes. We conducted a clinical epidemiological analysis to investigate the association of malnutrition with hospitalized duration in patients with COVID-19. Design: Retrospective survey study. Setting: Taikang Tongji (Wuhan) hospital in Wuhan, China. Participants: 139 patients with COVID-19. Methods: In total, 139 patients with COVID-19 from patients in the Infection Department of Taikang Tongji (Wuhan) hospital from February 2020 to April 2020 were analyzed retrospectively. We used the Global leadership Initiative on Malnutrition( GLIM) assessment standard published in 2019 to assess nutritional status. Prolonged hospitalization was lasting more than the median value of the hospitalized days (17 days) in this population. Results: According to the assessment results of GLIM nutrition assessment, the patients were divided into malnutrition group and normal nutrition group. Compared with the patients in the normal nutrition group, the hospitalization time was longer(15.67 +/- 6.26 days versus 27.48 +/- 5.04 days, P = 0.001). Kaplan-Meier analysis showed patients with malnutrition were more likely to be hospitalized longer compared with those normal nutrition (mean with 95% confidence interval [CI]: 28.91[27.52-30.30] versus 22.78[21.76-23.79], P = 0.001). COX regression analysis showed that malnutrition (hazard ratio [HR] = 3.773, P for trend = 0.001) was proportional associated with being discharged from hospital delayed. Conclusion and implications: Present findings suggested that malnutrition contributed to predicting a probability of prolonged hospitalization in patients with COVID-19 infection, to whom extra attentions and precautions should be paid during clinical treatments. Based on the existing results, it is recommended that inpatients with nutritional risk or malnutrition start nutritional support treatment as soon as possible.

Automated summary

The study found that malnutrition may lead to prolonged hospitalization in patients with COVID-19, and extra attention and precautions should be taken during clinical treatments for these patients.
