MethodsWe performed a retrospective cohort study of patients hospitalized between 2010 and 2015. Patients were identified using information recorded in hospital discharge reports (ICD-9-CM codes 415.11 and 415.19). ResultsWe included 965 patients with a median stay of 8 days (IQR 6–13 days). Higher scores on the simplified Pulmonary Embolism Severity Index (sPESI) were associated with increased probability of longer hospital stay. The probability of a hospital stay longer than the median was 8.65 (95% CI 5.42–13.79) for patients referred to the Internal Medicine Department and 1.54 (95% CI 1.07–2.24) for patients hospitalized in other departments, compared to those referred to the Pneumology Department. Patients with grade 3 on the modified Medical Research Council dyspnea scale had an odds ratio of 1.63 (95% CI: 1.07–2.49). The likelihood of a longer than median hospital stay was 1.72 (95% CI: 0.85–3.48) when oral anticoagulation (OAC) was initiated 2–3 days after admission, and 2.43 (95% CI: 1.16–5.07) when initiated at 4–5 days, compared to OAC initiation at 0–1 days. ConclusionssPESI grade, the department of referral from the Emergency Department, the grade of dyspnea and the time of initiating OAC were associated with a longer hospital stay. ER -
