Background: Acute heart failure (HF) patients most of the time present with hemodynamic instability, which often leads to prolonged bed rest. Despite its efficacy, early mobilization practice has not always been done due to several barriers in the medical professionals’ perspective, especially regarding safety and efficacy. Prior studies had shown that medical professionals’ views would greatly affect patients’ perspectives, especially in HF rehabilitation. This study aims to describe medical professionals’ views on the safety of early mobilization for HF. Methods: An online survey was circulated among specialists and general practitioners (GP) on their point of view on early mobilization of HF patients. Results: It was revealed that GP (n ¼ 104) were largely unsure or against early mobilization (49% agree, 33% unsure, and 18% disagree), as compared with the residents’/specialists’ group (n ¼ 93, 71% agree, 5% unsure, and 24% disagree). The presence of intravenous (IV) line, geriatric patients, and high risk of fall, were rated significantly higher as barriers for GP as compared with the residents or specialists’ group (p < 0.05). Conclusions: It is evident from this study that more education on early mobilization for HF patients should be available for medical professionals. © 2023 Medcom Limited. All rights reserved.
