Shortness of breath upon hospital admission or discharge predicts significantly higher death risk, a Harvard study finds.
Hospital patients reporting shortness of breath, or dyspnea, face up to six times higher risk of death, according to a Harvard Medical School study of nearly 10,000 patients.
The research, published in ERJ Open Research, found that severe breathing discomfort upon admission or at discharge strongly predicted mortality, with 25% of patients still experiencing breathlessness at discharge dying within six months.
Unlike pain, which showed no link to death, dyspnea was tied to higher ICU transfers and rapid response activations.
The study suggests routinely asking patients to rate their breathing difficulty—taking just 45 seconds—could help identify high-risk individuals early and improve care, though further research is needed to confirm benefits across diverse hospitals.
