Pneumonia, Depression, and Mortality are Impacted by Feeding Route in Patients With Dysphagia.

Background: Liquid nutrition delivered through a tube is often used amid difficulty swallowing. Tube feeding has been shown to have a relationship to pneumonia and mortality. Aim: Researchers investigated the relationship of feeding route (oral or tube) to patient outcomes. Design: Data were collected on outcomes (pneumonia, depression, mortality), feeding route, presence/absence of dysphagia, and covariates (chronic obstructive pulmonary disease [COPD], stroke, mortality risk, illness severity, sex, age). Researchers collected data over a 45-month period to ensure an adequate sample size for matching. The method of sampling was retrospective, archival data analysis. Propensity score analysis resulted in 94 matched, balanced pairs. Covariates were isolated from the treatment effect. Participants: The records of 2,180 inpatients treated by Palliative Medicine were considered, and 292 met the inclusion criteria. Results: Results revealed 10.14 times greater odds of pneumonia (OR = 10.14; p <.001) with tube feeding compared to oral feeding in patients with dysphagia and end-stage COPD or end-stage stroke. Results also revealed increased odds of depression (OR = 2.79; p =.01) and mortality (OR = 3.02; p <.01) with tube feeding compared to oral feeding. Conclusion: Study findings should encourage consideration of oral nutrition at the end of life. [ABSTRACT FROM AUTHOR]
