Delivering remote pulmonary rehabilitation in Bangladesh: a mixed-method feasibility study

BACKGROUND: Pulmonary rehabilitation (PR) is an effective and essential component of care for the increasing number of individuals with chronic respiratory diseases (CRDs). Despite the benefits, it remains underutilised and poorly accessible in low- and middle-income countries (LMICs). We aimed to determine the feasibility of delivering PR in Bangladesh at home because of pandemic travel restrictions.

METHODS: Aligned with the Medical Research Council framework of development and evaluation of complex interventions, we recruited individuals with CRDs from the Community Respiratory Centre, Khulna, to a mixed-methods feasibility study. We assessed their functional exercise capacity and quality of life before and after an eight-week course of home PR, and conducted semi-structured interviews with PR providers and professional stakeholders by using a topic guide aligned with the normalisation process theory (NPT) and interpreting the findings within its constructs.

RESULTS: We recruited 51 out of 61 referred patients with a range of CRDs, of whom 44 (86%) completed ≥70% of their home PR course. Functional exercise capacity, measured by the endurance shuttle walk test, improved in 78% of patients, with 48% exceeding the minimum clinically important difference (MCID). Health-related quality of life, measured by the Chronic Obstructive Pulmonary Disease Assessment Test, improved by more than the MCID in 83% of patients. Through the interviews, we found that PR providers encountered challenges in remote video supervision due to unstable internet connections, forcing them to resort to telephone calls. The strength of support for NPT constructs varied; many participants understood and appreciated the role of PR and could make sense of the innovation (NPT-1), and most were assessing the potential of a PR service in Bangladesh to decide if it was worthwhile (NPT-4). Participants were not yet ready to endorse or actively support (NPT-2) or operationalise (NPT-3) the roll-out of PR.

CONCLUSIONS: A home PR programme, supported by remote supervision and monitoring, is feasible in Bangladesh, but local evidence will be needed to promote implementation.
