ContextThe trajectory of dyspnea for patients hospitalized with acute cardiopulmonary disease, who are not terminally ill, is poorly characterized.ObjectivesTo investigate the natural history of dyspnea during hospitalization and examine the role that admission diagnosis, and patient factors play in altering symptom resolution.MethodsProspective cohort study of patients hospitalized for an acute cardiopulmonary condition at a large tertiary care center. Dyspnea levels and change in dyspnea score were the main outcomes of interest and were assessed at admission, 24 and 48 hours, and at discharge using the verbal 0-10 numeric scale.ResultsAmong 295 patients enrolled, the median age was 68 years, and the most common admitting diagnoses were heart failure (32%), chronic obstructive pulmonary disease (COPD) (39%), and pneumonia (13%). The median dyspnea score at admission was 9 (interquartile range [IQR] 7-10); decreased to 4 (IQR 2-7) within the first 24 hours; and subsequently plateaued at 48 hours. At discharge, the median score had decreased to 2.75 (IQR 1-4). Compared to patients with heart failure, patients with COPD had higher median dyspnea score at baseline and admission and experienced a slower resolution of dyspnea symptoms. After adjusting for patient characteristics, the change in dyspnea score from admission to discharge was not significantly different between patients hospitalized with congestive heart failure, COPD, or pneumonia.ConclusionMost patients admitted with acute cardiopulmonary conditions have severe dyspnea on presentation, and their symptoms improve rapidly after admission. The trajectory of dyspnea is associated with the underlying disease process. These findings may help set expectations for the resolution of dyspnea symptoms in hospitalized patients with acute cardiopulmonary diseases.Copyright © 2016 American Academy of Hospice and Palliative Medicine.
