Pulmonary rehabilitation in Africa: where are we? a multimethod study
Bibliographic record
Abstract
Pulmonary rehabilitation (PR) is an integral part of the management of patients with chronic respiratory diseases. However, there is limited information available on the effectiveness and practice of PR in Africa. This study was conducted to examine the prevalence, structure, and organization of PR in Africa, as well as its substance and claimed efficacy. We conducted a multimethod study involving systematic review of PR studies (obtained from PubMed, Google Scholar, and Cochrane databases) and a web-based survey of African healthcare professionals engaged in PR (using a standardized questionnaire). The review included papers on at least one component of PR in Africa and excluded those on PR from other continents or assessing pulmonary disorders in general without PR, cardio-rehabilitation, or physiotherapy practice in general in Africa. The Cochrane risk of bias and the Newcastle Ottawa scale instruments were used to assess the quality of included studies. We narratively synthesised data across the studies to produce a holistic picture. Of the 14 studies included for qualitative synthesis, seven were randomized controlled trials on the effectiveness of PR treatments with a total number of 333 participants. Of the 39 surveys mailed to health professionals working in Africa, only 14 (35.8%) were returned. We found aerobic exercise and breathing exercises were the most used technique and that quality of life, exercise capacity, and lung function improved significantly after PR treatments. There were differences in the duration, frequency, and length of the programs across the continent. Half of the respondents indicated that their institutions had one or more PR programs for inpatient, outpatient, maintenance, and/or home-based programs. Additionally, aerobic activities, upper and lower extremity strength training were the most frequently used exercise modalities in PR programs, followed by breathing exercises. Pulmonary rehabilitation is understudied in Africa, but it has been linked to improved lung function, exercise capacity, and quality of life. There is a need to invest in techniques tailored to the continent to enhance the implementation of pulmonary rehabilitation in Africa.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
