Title: Undernutrition risk at hospital admission and length of stay among pulmonology inpatients.
Issue Date: 2018
Abstract: Background: There is a lack of evidence regarding the association between the undernutrition risk at hospital admission with adverse clinical outcomes amongst pulmonology inpatients. The aim of this study was to quantify the association between undernutrition risk at hospital admission and time to discharge alive. Methods: A retrospective cohort study including patients consecutively admitted to a pulmonology unit was conducted. Undernutrition risk at hospital admission was identified using the Malnutrition Universal Screening Tool. Survival analyses (Kaplan–Meier curves and Cox regression) were carried out. Results: The sample was composed of 683 patients. Patients who presented high undernutrition risk on hospital admission had a longer length of hospital stay (approximately 50% were discharged to home after 14 days of hospitalization). In the multivariable Cox regression, high undernutrition risk was shown to be independently associated with a lower probability of discharge alive over time (adjusted hazard ratio = 0.70; 95% confidence interval: 0.55–0.90). Conclusions: Pulmonology inpatients with high undernutrition risk have a longer length of hospital stay and had a lower probability of being discharged to home. In particular, lung cancer patients had a lower probability of being discharged to home, which corroborates a worse prognosis for these patients.
