A public health development intervention between acceptability and feasibility: descriptive-interpretive discussion...

the National Tuberculosis Control Program (NTP) in Cameroon participated between 2016 and 2018 in a multi-country operational study of the Union against Tuberculosis and Lung Disease (The UNION) aiming at demonstrating the efficiency and feasibility of systematic tuberculosis preventive treatment (TPT) with 3 months of an isoniazid/rifampicin (3RH) combination in under-five child contacts of bacilliferous TB patients. Cameroon was one of the participating countries of the study. Despite the promising results communicated following this study, the coverage of TPT with 3RH in Cameroon remains low. We explored the intervention under aspects of acceptability and perceived feasibility.

key participants and stakeholders in this descriptive interpretative study in Cameroon were interviewed in five focus groups or individually (31 individuals). The Focus Group Discussion (FGD) and interview transcripts were analysed for different components of acceptability using a theoretical framework and the results discussed confronting them with the main objective of the study, i.e. demonstrating feasibility.

the children's parents expressed overall positive feelings about and acceptance of the intervention, emphasizing the unexpected empathy shown by the health staff. The involved field staff, too, showed unreserved acceptance. On the other hand, managers at the intermediate and central levels showed scepticism as to the process of initiation of the study as well as to its feasibility in the given context, neglecting aspects of resources necessary for a scaling-up and of prioritisation.

the adoption of a public health strategy, also internationally recognized as an effective and efficient intervention, requires more than the demonstration of its acceptability or feasibility during the term of a showcase project introduced by an external development partner. Adoption is conditioned by adoption and circumspect planning involving at each stage the stakeholders on all levels of the program.
