Early mobilization for acute heart failure: A scoping and a systematic review

Early mobilization of hospitalized patients is beneficial under certain circumstances. This has been applied in clinical practice for patients with acute heart failure (HF). However, its current definition, effectiveness, and safety are not well established. This review aimed to clarify the current definition of “early mobilization,” and summarize its effectiveness and safety in acute HF. We conducted a scoping review to define early mobilization (Part 1) and a systematic review and meta-analysis (Part 2) to evaluate its effectiveness and safety. For Part 1, we searched MEDLINE (Ovid), and for Part 2, we searched the Cochrane Central Register of Controlled Trials, MEDLINE (Ovid), Embase (ProQuest Dialog), CINAHL, and PEDro. We included 12 studies in Part 1 and defined early mobilization as protocol-based interventions or walking within 3 days of admission. Based on this definition, two observational studies were included in Part 2, with no randomized controlled trials. Early mobilization may result in a large reduction in the readmission rate compared with that of the control (two studies, 283 participants: odds ratio 0.25, 95 % confidence interval 0.14 to 0.42; I2 = 0 %; low certainty evidence). We could not define frequency, intensity, or quantity because many of the included studies did not describe them. In conclusions, our review suggests that early mobilization, defined as protocol-based interventions or walking within 3 days of admission, may be associated with a low readmission rate in patients with acute HF. Future studies are essential, to investigate the causal relationship between early mobilization and possible outcomes.
