Clinical factors associated with non-compliance with indicators of prescribed and infused volume of enteral nutrition therapy.

Objective: to evaluate the factors associated with non-compliance with the Quality Indicators in Nutritional Therapy (QINT) related to the prescribed and infused volume of Enteral Nutritional Therapy (ENT). Method: cross-sectional study, aligned with a prospective cohort, carried out in two clinical wards and two surgical wards of a Brazilian public hospital of high complexity and reference in ENT. Patients aged > 18 years, of both sexes, who required ENT exclusively by tube were included. The QINT "enteral volume infused index" and "frequency of days of adequate administration of the prescribed volume X volume infused in patients on ENT" were analyzed. Multivariate Poisson regression was adopted to identify factors associated with the outcome. Results: the 159 patients included totaled 565 days using ENT. The independent risk factors for non-compliance with the "enteral volume infused index" indicator were: being a surgical patient (HR: 2.12; 95 % CI: 1.31-3.41; p = 0.002), the presence of chronic obstructive pulmonary disease (COPD) (HR: 2.34; 95 % CI: 1.54-3.57; p = 0.002) and use of antidiarrheals (HR: 2.35; 95 % CI: 1.45-3.80; p = 0.001). The use of antidiarrheals (HR 19.75; 95 % CI: 10.05-38.79; p = 0.000) was the only risk factor identified for non-compliance with the indicator "frequency of days of adequate administration of the prescribed volume X volume infused in patients on ENT." Conclusions: surgical patients, those with COPD, and those using antidiarrheals are at greater risk of not reaching the prescribed ENT volume over the prescribed days.
