NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer-review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer-Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Effectiveness of Pulmonary Rehabilitation on Exercise Capacity in Adult Patients with Lung Transplantation: Single-Arm Meta-analysis
ABSTRACT
Background:
Lung transplantation (LTx) is a well-established option for patients in the end-stage lung disease that is not responsive to other treatments. Although the survival rate after LTx has seen a significant increase, exercise intolerance still limited and poses a big obstacle to recovery after LTx. Pulmonary rehabilitation (PR) is a comprehensive intervention that has many benefits for patients with chronic respiratory disease. However, the effectiveness of PR on adult patients with LTx is inconclusive. We performed this meta-analysis to assess the efficacy of PR in adult LTx recipients.
Objective:
The purpose of this meta-analysis was to explore the effectiveness of PR on exercise capacity in adult patients with LTx.
Methods:
Eligible randomized controlled trials (RCTs) and quasi-experimental studies published until March 25, 2024 2024, were searched in MEDLINE, Embase, Web of science and CINAHL. Additionally, reference lists and published systematic reviews were scanned by manual searching. Studies selection, data extraction, and risk of bias assessment were conducted independently. Stata software (version 17.0) was utilized.
Results:
21 studies (9 RCTs and 12 quasi-experimental studies) were identified. Pooled analysis showed that PR positive effect in improving six minutes walking distance(6MWD) (SMD 1.28, 95% CI 1.05–1.50, P<0.001), maximum oxygen consumption (VO2max) (SMD 0.42, 95%CI 0.15-0.68, P=0.002), handgrip force (HGF) (SMD 0.49, 95% CI 0.26–0.73, P<0.001), and quadriceps force (QF) (SMD 0.63, 95% CI 0.45–0.82,P<0.001). There was no significant publication bias in those outcomes mentioned above.
Conclusions:
PR shows evidence of being an effective adjunctive strategy for improving exercise capacity after lung transplantation, but multi-center trials on larger populations are required to confirm its clinical benefits in the real-world setting. Clinical Trial: This meta-analysis protocol was registered with PROSPERO(NO. CRD42023460247)
