The Clinical Impact of Implementation of a Nutritional Treatment Protocol in Critically Ill Adults with SARS-CoV-2 Infection

Introduction:The critical patient affected by SARS-CoV-2 is at risk of malnutrition. The need to avoid volume overload and manoeuvres that delay reaching nutritional requirements such as pronation make the nutritional approach to these patients complex. To ensure adequate treatment, a nutritional support protocol was developed as a clinical practice guideline adapted to the COVID-19 patient.Objective:To describe and analyse the results of introducing a nutritional support protocol aimed at SARS-CoV-2 patients admitted to the intensive care unit (ICU) of the Consorcio Hospital General Universitario de Valencia (CHGUV) from March to May 2020.Material and methods:Observational, descriptive, retrospective and longitudinal design to evaluate compliance with a nutritional support protocol.Results:Thirty-one consecutive patients were included but nutritional follow-up could not be performed in eight. Of the remaining 23 patients, only eight reached 80% of caloric requirements before the tenth day after starting treatment (good compliance group) and 15 after the eleventh day (poor compliance group). In the group with «good compliance» 75% (n = 6) were discharged and 25% died (n = 2), compared to the group with «bad compliance» where 53% (n = 8) were discharged and 47% (n = 7) died (Chi square test, p-value = 0.019). Those patients who reached 80% of caloric needs during ICU stay had a shorter length of stay compared to those who did not (median days of admission = 14, IQR = 10-16 and median days of admission = 22, IQR = 13-39, p-value = 0.025).Conclusions:Introducing a nutritional protocol during the first weeks of the SARS-CoV-2 pandemic could improve clinical outcomes by promoting healing and reducing associated complications.
