Abstract
INTRODUCTION AND OBJECTIVE The Bronchiectasis Health Questionnaire (BHQ) is a simple, repeatable, and self-reporting health status questionnaire for bronchiectasis. This study aims to cross-culturally adapt the BHQ into Brazilian Portuguese and evaluate its measurement properties. METHODS The participants answered the Saint George...s Respiratory Questionnaire (SGRQ) and the modified Medical Research Council (mMRC) scale for dyspnea. The Brazilian-Portuguese version of the Bronchiectasis Health Questionnaire (BHQ-Brazil) was used at baseline (test) and after 14 days (retest). The psychometric analyses included internal consistency, test-retest reliability, and construct validity: factorial validity, convergent validity, and discriminative validity, agreement, and ceiling and floor effects. RESULTS The BHQ-Brazil demonstrated adequate internal consistency (Cronbach...s alpha...=...0.92) and substantial reliability (intraclass correlation coefficient...=...0.86; 95%CI: 0.79...0.90). The exploratory factorial analysis was considered suitable. All items presented a factorial load >0.40. The convergent validity of the BHQ-Brazil with mMRC was moderate (r...=......0.53, p...<...0.001), while concurrent validity with the SGRQ was strong (symptoms: r...=......0.72, activities: r...=......0.60, impact: r...=......0.60, total score: r...=......0.75, all p...<...0.001). The standard error of measurement was 4.81 points. The discriminative validity demonstrated that individuals with more pulmonary exacerbations, colonization by Pseudomonas aeruginosa, worst dyspnea, and a higher number of affected lung lobes presented the lowest quality of life. No floor or ceiling effects were observed. CONCLUSION The BHQ-Brazil presents adequate measurement properties to evaluate the impact of bronchiectasis on health-related quality of life, and can be used in clinical and research settings.

Home-based pulmonary rehabilitation in people with bronchiectasis: a randomised controlled trial. ERJ Open Res 2021; 7:00021-2021. [PMID: 34084777 PMCID: PMC8165366 DOI: 10.1183/23120541.00021-2021] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 03/31/2021] [Indexed: 11/18/2022] Open
Abstract
Aim To investigate the short- and long-term effects of home-based pulmonary rehabilitation (HBPR) on functional capacity, quality of life, peripheral muscle strength, dyspnoea and daily physical activity in people with bronchiectasis. Methods Randomised controlled trial with 63 participants with bronchiectasis. The HBPR group performed three sessions per week for 8 weeks (aerobic exercise: step training for 20 min; resistance training: exercises for quadriceps, hamstrings, deltoids and biceps brachii using elastic bands). The control group received a recommendation to walk at moderate intensity, three times per week. A weekly phone call was conducted for all participants, and the HBPR group received a home visit every 15 days. The primary outcome was distance in the incremental shuttle walk test (ISWT). Secondary outcomes were time in the endurance shuttle walk test (ESWT), number of steps in the incremental step test, quality of life, quadriceps muscle strength and daily physical activity. Measures were taken before and after intervention and 6 months later. Results After the intervention, the HBPR group had increased ISWT distance compared with the control group with between-group difference 87.9 m (95% CI 32.4–143.5 m). In addition, between-group differences were found in the ESWT, incremental step test, quality of life and quadriceps muscle strength, favouring the HBPR group. After 6 months, no differences were observed between the groups. Conclusion HBPR is an effective alternative offering of pulmonary rehabilitation for people with bronchiectasis. However, the programme was not effective in maintaining the benefits after 6 months of follow-up. Home-based pulmonary rehabilitation (HBPR) delivers improvements in functional capacity, peripheral muscle strength and QoL in people with bronchiectasis. HBPR is safe, well tolerated and can be considered an alternative rehabilitation programme.https://bit.ly/2Q2Bout
