Physiotherapy management of bronchiectasis in adults

Development of a core outcome set for physiotherapy trials in adults with bronchiectasis (the COS-PHyBE study): A Delphi study and consensus meeting

Background

Physiotherapy is recommended for bronchiectasis management, but there is disparity in evidence supporting its use. This is partly because of inconsistency and poor reporting of outcomes in available studies. A Core Outcome Set (COS) may improve trial consistency and decrease reporting bias. This study aimed to develop a COS for physiotherapy clinical trials in adults with bronchiectasis.

Methods

A comprehensive list of outcomes was developed using a systematic review and qualitative semi-structured interviews with patients with bronchiectasis and physiotherapists.An international two-round online Delphi survey was conducted. Outcomes scored 7-9 (crucial) by ≥ 70 % of participants and 1-3 (not that important) by ≤ 15 % of participants from each stakeholder in the Likert scale were nominated for inclusion in the COS. Nominated outcomes and those considered crucial by only one of the stakeholders' groups were further discussed and voted in an international consensus meeting.

Results

A list of 137 outcomes was generated; 104 from literature and 33 from interviews. A Delphi survey containing 59 outcomes was completed by 171 participants from 20 countries. After the consensus meeting, representatives agreed on seven outcomes: health-related quality of life, respiratory symptoms, physical functioning, emotional and psychological functioning, fatigue, adherence to treatment, and functional exercise capacity.

Conclusion

A minimum set of seven outcomes are recommended to be included as measurements in future trials evaluating physiotherapy interventions for bronchiectasis.

Physiotherapy-led, community-based airway clearance services for people with chronic lung conditions: a retrospective descriptive evaluation of an existing model of care

OBJECTIVES

Airway clearance interventions are recommended for people with chronic lung conditions and mucus hypersecretion, but there are few published models of care or descriptions of airway clearance service provision. This evaluation describes a dedicated, physiotherapy-led, community-based airway clearance service in a metropolitan local health network.

DESIGN

Retrospective evaluation using existing airway clearance service administrative database.

PARTICIPANTS

All first referrals to the airway clearance service in a 5-year period (1/1/2017 to 31/12/2021).

MAIN OUTCOME MEASURES

Available service data grouped into four domains: participant demographics, referral demographics, service provision and outcomes.

RESULTS

Of the 1335 first referrals eligible for inclusion, 1157 (87%) people attended. Bronchiectasis was the commonest condition (n = 649/1135, 49%). A total of 2996 occasions of service (face to face clinic n = 2108, 70%, phone n = 736, 25%, telehealth n = 99, 3%, home visit n = 53, 2%) were delivered. Airway clearance devices frequently prescribed were the Aerobika (525/1157, 45%), bubble-positive expiratory pressure (263/1157, 23%) and the Acapella (127/1157, 11%). On average, initial appointment with the airway clearance service occurred within 36 days of referral and people attended the service three times. Individuals voluntarily completed both pre/post service questionnaires around a third of the time. At least half of responders reported an improvement in respiratory symptom outcome measures consistent with the minimum clinically important difference.

CONCLUSIONS

This evaluation describes an airway clearance service as it exists, providing an example from which airway clearance services can be planned, implemented and improved.

Outcomes of physiotherapy for people living with bronchiectasis: qualitative study to inform development of a core outcome set

INTRODUCTION

Evidence of the effectiveness of physiotherapy for bronchiectasis is inconsistent, partly due to variation in the selection and reporting of outcomes in clinical trials. This qualitative study is a component of the development of a core outcome set (COS). The COS will identify a minimum group of outcomes for use in clinical trials of physiotherapy considering the views of researchers, patients, and clinicians.

OBJECTIVES

To identify outcomes for use in physiotherapy research that are important to patients and physiotherapists and to explain their significance.

METHODS

Semi-structured interviews were conducted with adult patients with bronchiectasis who received physiotherapy, in addition to physiotherapists clinically involved in bronchiectasis care. Interviews were audio recorded and transcribed verbatim. Thematic analysis was used to identify, classify, and explain the significance of outcomes. Outcomes were mapped into the list created from literature review and classified into domains.

RESULTS

We interviewed 18 participants from four countries covering a range of experiences in different settings. Seventy outcomes were identified and grouped into 15 domains. Thirty-three outcomes were not previously reported in the literature. Thematic analysis revealed exacerbations, quality of life, use of healthcare resources, patient-reported symptoms, physical functioning, and sputum as the prominent themes reported by both patients and physiotherapists.

CONCLUSIONS

This qualitative study highlighted the importance of considering stakeholder perspectives when planning research trials. Outcomes identified will be used to inform the next phase of COS development.
