RESUMO

INTRODUCTION: High-frequency chest wall oscillation (HFCWO) devices are used to improve airway clearance in various respiratory conditions. This study comprehensively assesses the evidence on efficacy and safety and identifies trends in scientific publications and patents across geographic regions. METHODS: This study utilized an integrated approach, combining bibliographic and bibliometric research with artificial intelligence (AI) tools. Four databases - PubMed, Europe Pubmed Central, Cochrane Database of Systematic Reviews, and CINAHL - were searched for systematic reviews on the effectiveness of treatment options for HFCWO. The AMSTAR-2 tool was used to evaluate the risk of bias in systematic reviews. Bibliographic research synthesized the evidence following PRISMA and Cochrane guidelines. The Dimensions platform was used for bibliometric analysis to provide insights into the global landscape. AI tools with prompt engineering tools Chain-of-Thoughts (CoT) and Tree of Thoughts (ToT) were used to enhance data extraction capabilities. RESULTS: The umbrella review identified 12 systematic reviews supporting the effectiveness of HFCWO in improving pulmonary function parameters, sputum characteristics, dyspnea, health scores, and quality of life in conditions including cystic fibrosis, bronchiectasis, chronic obstructive pulmonary disease (COPD), or neuromuscular diseases, with varying evidence of certainty. Eight of the twelve reviews had a moderate to high AMSTAR-2 confidence level, while several studies lacked sufficient descriptions of methods, treatment regimens, outcome measures, and adverse effects. Despite the absence of adverse events, the overall evidence quality between studies is evaluated as low to very low. Bibliometric analysis found a significant increase in global interest over the past two decades, with 230 research publications, 137 patents, and 56 clinical trials. CONCLUSIONS: The study highlights the potential of HFCWO devices in respiratory care but demands more robust evidence. The increasing interest in airway clearance devices highlights the necessity for HFCWO mechanism and safety research, underlining its therapeutic relevance in respiratory medicine. The interdisciplinary integration of AI tools and prompt engineering contributes to a nuanced understanding of the available evidence.
