TB patients learning about second hand smoke (TBLASS): a pilot individual randomised controlled trial, Pakistan

This pilot trial is aimed to develop and evaluate a behavioural intervention 'Smoke Free Homes (SFH)' for tuberculosis patients to encourage them to negotiate a smoke free environment within their homes. It will inform the design of a future definitive trial. The SFH intervention was developed using taxonomy of behaviour change techniques to encourage families of non-smoking TB patients to implement smoking restrictions at home following a logic model of the intervention. The intervention was piloted in two routine National TB Programme hospitals. The eligible TB patients, attending the trial sites were randomised and allocated to one of the two trial arms (“individual based care” and “individual based care” plus “supplementary support”). We recruited 75 participants in each arm. The primary outcome measure was SFH of participant by validating through 'Urine Cotinine' test. We also determined qualitatively the barriers and key drivers to the creation of smoke free homes.
