SHM Converge Scientific Abstract ePoster Gallery-Aspiration Timeline in Patients With Hospital-Acquired Sepsis and Aspiration Pneumonia

Pdf Summary

This retrospective cohort study examined the timing of aspiration relative to hospital-acquired sepsis (HAS) in patients with aspiration pneumonia at a tertiary academic medical center from July 2022 to February 2023. The study reviewed charts for all patients with ICD-10 codes for HAS and aspiration pneumonia/pneumonitis. Severe sepsis timing was identified using an electronic health record alert, and aspiration timing was determined from radiology reports or progress notes.<br /><br />Among 399 patients with HAS, 48 (12%) had confirmed aspiration pneumonia/pneumonitis. Of these, 43 had both sepsis and aspiration timestamps available. In most cases, severe sepsis was recognized before aspiration occurred: 30 of 43 patients (70%) had a sepsis alert prior to documented aspiration, with a median lead time of 19 hours. Only 17 of 43 patients (40%) were on aspiration precautions before the first aspiration event.<br /><br />There were no significant demographic differences between patients whose sepsis alert came before aspiration and those whose aspiration came first. Timing of aspiration relative to sepsis was not significantly associated with use of aspiration precautions, level-of-care escalation after aspiration, or in-hospital mortality.<br /><br />Overall, the findings suggest that aspiration was usually not the initial trigger for HAS in this population. Instead, HAS may predispose patients to aspiration. The authors recommend further research to determine whether sepsis itself increases aspiration risk and whether earlier aspiration precautions in high-risk patients could improve outcomes.
