Estimation of the health economic benefit of widening pulmonary rehabilitation uptake and completion.

Increasing uptake and completion of Pulmonary Rehabilitation in people with COPD has the potential to deliver health benefit and reduce health inequalities. We have quantified the cost-effectiveness of enhancing PR access and completion by reviewing the cost-effectiveness literature for PR in COPD. A literature review identified studies that provided cost-effectiveness evidence for PR compared to no PR. The key metrics of interest were healthcare resource use and cost savings, and quality adjusted life year (QALY) gains. Healthcare resource use data were valued using the UK NHS National Tariff 2022/23. From the literature search we identified the QALY gain resulting from completion of PR. The value of the QALY gain resulting from PR completion was calculated using the standard willingness-to-pay threshold of £20,000 considered by the UK National Institute for Health and care Excellence (NICE). We estimated a QALY gain resulting from completion of PR of 0.065 and value of the QALY gain was therefore calculated to be £1300 per person completing PR. We estimated the 12 month reduction in hospitalisation following completion of PR to be 8.2% giving a total cost reduction per patient of £245. We therefore calculated that up to £1545 could be spent per person with COPD to deliver PR cost-effectively. Our analysis provides commissioners with the information they need to make informed decisions about planning and provision of PR. The data allows estimation of additional resources that could be deployed in addressing inequitable access to PR among disadvantaged and underserved populations whilst retaining cost effectiveness of the intervention.
