Key result
Adding ED visits or complications to discharge models identifies only ~25% of post-discharge PEs.
Why the study?
Current approaches to extended chemoprophylaxis after metabolic-bariatric surgery rely primarily on discharge-based risk assessment, but post-discharge emergency department encounters and serious complications may identify additional patients at risk.
Does dynamic reassessment incorporating post-discharge ED encounters or serious complications improve identification of post-discharge pulmonary embolism in patients undergoing metabolic-bariatric surgery compared to discharge-only prediction models?
Cohort (n=949,289)
Yes
Does dynamic reassessment incorporating post-discharge ED encounters or serious complications improve identification of post-discharge pulmonary embolism in patients undergoing metabolic-bariatric surgery compared to discharge-only prediction models?
Current discharge-based risk calculators and dynamic reassessment fail to identify the vast majority (nearly 75%) of patients who develop post-discharge pulmonary embolism after metabolic-bariatric surgery.
No takes yet. Share an insight, caveat, or question.
Discharge prediction models miss most post-discharge PE after bariatric surgery; hypothesis-generating for improved dynamic risk tools.
Dallal et al. (2026) conducted a cohort in Pulmonary embolism after metabolic-bariatric surgery (n=949,289). Discharge-based risk assessment and reassessment after ED encounters or serious complications was evaluated on Post-discharge pulmonary embolism. Discharge-based risk calculators identified only 7.9% of post-discharge pulmonary embolisms, and adding ED encounters or serious complications increased identification to just 25.2%.
