Key Takeaway
Note: This is a protocol; no results yet. Await the completed umbrella review before changing practice.

This publication is a protocol for an umbrella review, designed to synthesize evidence on early rehabilitation (ER) for critically ill adult patients in the intensive care unit (ICU). The protocol outlines plans to evaluate the effectiveness and safety of ER, as well as to assess the methodological quality of existing systematic reviews and the certainty of evidence for key outcomes. No results are reported because the search and analysis have not yet been completed.

The authors note that no high-level evidence synthesis has comprehensively appraised the current evidence base on this topic, which is a key gap this umbrella review aims to fill. The protocol does not specify a comparator, follow-up duration, or sample size, and no effect sizes or safety data are available at this stage.

Given that this is a protocol, the findings are not yet available, and the clinical implications remain uncertain. The review may eventually inform evidence-based clinical decision-making, support standardized protocol development, and identify priority evidence gaps for future primary research. However, clinicians should interpret any future results with caution until the full review is published and critically appraised.

When a patient survives a life-threatening illness in the intensive care unit, the road to recovery can be long and difficult. These patients often face post-intensive care syndrome, which includes lasting physical and mental challenges. To help these survivors, many doctors use early rehabilitation to jumpstart the healing process.

A new research plan aims to gather all available evidence on this specific treatment. Because there is currently no high-level summary of what works best for these patients, researchers need a clear way to judge the quality of existing studies. This upcoming review will look closely at both how well early rehabilitation works and whether it is safe for those who are very ill.

While this study does not provide immediate results yet, it is a necessary step toward creating standard rules for hospital care. By identifying where information is missing, the project helps doctors make better decisions for patients who need help getting their lives back after a critical illness.

What this means for you:
A new research plan aims to clarify how early rehabilitation helps adults recover from intensive care stays.

Common questions

What is early rehabilitation for ICU patients?

Early rehabilitation involves starting physical or supportive therapies shortly after a patient is admitted to or stays in an intensive care unit. The goal is to help critically ill adults regain strength and function as soon as it is safe to do so.

Is early rehabilitation safe for people who are very sick?

The researchers are specifically looking into the safety of these programs. Because this is a protocol for a future review, specific safety data and side effects have not been reported yet in this particular study.

How will this research help patients?

By creating a high-quality summary of existing evidence, this work helps doctors create standard protocols. This can lead to better clinical decisions and more consistent care for adults recovering from severe illnesses.

BackgroundAdvances in critical care medicine have improved short-term survival for intensive care unit (ICU) patients, yet a large proportion of survivors experience lasting physical, cognitive, and psychological impairments collectively termed post-intensive care syndrome (PICS). Early rehabilitation (ER) is a core strategy to reduce PICS burden, but available systematic reviews (SRs) vary widely in intervention protocols, population scope, and methodological rigor. Evidence remains inconsistent regarding ER safety and efficacy in high-risk subgroups, and no high-level evidence synthesis has comprehensively appraised the current evidence base.ObjectiveThis protocol outlines an umbrella review (overview of systematic reviews) designed to synthesise evidence on the effectiveness and safety of ER in critically ill adult patients, evaluate the methodological quality of existing SRs, and grade the certainty of evidence for key outcomes.MethodsNine electronic databases (CINAHL, Cochrane Library, Embase, PubMed, Web of Science, CNKI, CBM, Wanfang, VIP) will be searched from inception to 30 April 2026, supplemented by manual reference screening and PROSPERO registry searches. Two independent reviewers will conduct title/abstract screening and full-text eligibility assessment, with disagreements resolved via consensus or third-party adjudication. Methodological quality of included SRs will be appraised using the AMSTAR 2 tool, and the certainty of evidence for primary outcomes will be graded using the GRADE framework. A narrative evidence synthesis will be performed to map findings across reviews; quantitative meta-analysis will only be conducted at the primary study level where methodologically appropriate, to avoid bias from overlapping study samples. Subgroup and sensitivity analyses will be undertaken to explore sources of heterogeneity.Anticipated contributionThis umbrella review will provide a rigorous, high-level synthesis of the current ER evidence base. If evidence certainty is sufficient, findings may inform evidence-based clinical decision-making, support standardised protocol development, and identify priority evidence gaps for future primary research.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/view/CRD420250651183, Registration No. CRD420250651183.
