Clinical Decision Guidelines
Background: Direct Oral Anticoagulants and pulmonary embolism (PE) risk prediction models like the Simplified Pulmonary Embolism Severity Index (sPESI) have questioned if it is necessary to admit all patients with PE. Research suggests it is safe and cost effective to discharge patients at low risk of major adverse events by scoring, however many emergency physicians (EPs) are unfamiliar and uncomfortable risk stratifying PE patients. The purpose of this study was to assess the impact of an institutional pathway for the disposition of PE patients on the stated preferences of EPs. We hypothesized introduction of a clinical pathway using an EHR-based sPESI calculator would be associated with increased preference for discharging patients with low risk PE.
