Short-term and Long-term Mortality Following Hospitalized and Ambulatory Lower Respiratory Tract Illnesses Among US Adults.

ABSTRACT:

Background

Lower respiratory tract illness (LRTI) is a significant cause of morbidity among adults, particularly older adults and adults with underlying medical conditions. Evidence on short- and long-term risks of mortality among adults requiring hospitalization or ambulatory care for LRTI, overall and within subgroups, is currently lacking.

A retrospective observational matched-cohort design and Optum's de-identified Clinformatics Data Mart Database (2012-2019) were used. The study population included adults who were hospitalized or received ambulatory care for LRTI and matched (1:1) comparison patients.
