There is limited evidence on the factors that predict the need for home oxygen, among these infectious and non-infectious hospital complications. Objective: To evaluate the role of hospital complications as factors associated with the requirement of home oxygen at hospital discharge and to estimate the frequency of infectious complications and noninfectious complications. Design: Concurrent prospective cohort Methodology: It was based on the population of the study Prescription of home oxygen at the time of hospital discharge and development of a model that predicts its requirement, composed of patients admitted to the emergency service of the Fundación Cardioinfantil between March 2017 and September 2017. Patients older than 18 years and those with hospital stay greater than or equal to 48 hours were included. Results: A total of 1227 patients were included, finding an 18% prescription of home oxygen. The frequency of non-infectious complications was 1.54% (95% CI 0.8% to 2.2%), and infectious complications were 5.3%% (CI 4.6 to 7.5%). In the association model adjusted for confounding variables, hospital complications were found to be a factor that is associated with 4 times more (p <0.001 IC 95% 2.4-6.73) to the need for home oxygen at discharge from hospitalization. Conclusion: There is an association between the need for home oxygen and hospital complications.
