Measurement properties of physical activity in adults with bronchiectasis: A systematic review protocol.

People with bronchiectasis reduce their physical activity (PA) due to muscle weakness, dyspnea, fatigue, reduced exercise capacity and frequent cough with expectoration. Patient-reported and objective physical assessment methods have been used to evaluate PA in people with bronchiectasis. In the literature, significant differences in the PA measured using patient-reported outcome measures when compared with the objective methods. Given the availability of many PA assessment tools, it is tedious for the clinician or researcher to choose an outcome measure for clinical practice or research. The evidence on validity and reliability in bronchiectasis are unclear. Objectives: To identify the PA assessment tools, describe and evaluate the literature on psychometric properties of instruments measuring and analyzing PA. Methods: The search will be conducted in PubMed/Medline, Cochrane Central Register of Controlled Studies, Scopus and EMBASE databases. The keywords, index terms and synonyms of the following words will be used: bronchiectasis, physical activity, and outcome measures. Published studies of adult with clinical and/ or radiologically diagnosed bronchiectasis, aged >18 years, any gender and studies that assessed PA and/or if there are reports on measurement properties of PA will be included in the review. Studies using qualitative research methods, narrative reviews, letters to editors and editorials will be excluded. The quality of the study will be assessed and data will be extracted. Any disagreement will be resolved in the presence of an author not involved in the screening or selecting studies. Discussion: By assessing the quality of studies on measurement properties, this review will help researchers choose the outcome measure to evaluate the effects of interventions on PA. This review will identify the suite of outcome measures of PA for people with bronchiectasis that can be used for research and clinical purpose.
