Updated guidelines for child and adolescent TB

A public health development intervention between acceptability and feasibility: descriptive-interpretive discussion of an example

Introduction

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.

Methods

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.

Results

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.

Conclusion

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.

Improving Tuberculosis Case Detection in Children: Summary of Innovations and Findings From 18 Countries

Despite a growing focus on the plight of tuberculosis (TB) among children, 56% of the 1.2 million children who develop TB annually are not detected and notified. TB REACH is a platform of the Stop TB Partnership that supports innovative interventions to improve TB case detection and preventative treatment. We present summary findings from 27 TB REACH-supported projects in 18 countries. Interventions were designed around intensified case-finding approaches (facility-based systematic screening and contact investigation), capacity building (including decentralized care delivery and supported decision-making), and improving diagnostic methods (ie, introduction of alternative respiratory specimens and new tools to aid the diagnosis). These interventions were evaluated on how they worked to identify children with TB, prevent further transmission of TB among children, and strengthen the health system involved with childhood TB care. Overall, 13 715 children were detected with TB, improving case notifications by 34%. In addition, nearly 5000 eligible contacts were enrolled on TB preventive treatment through these interventions. Focusing efforts and funding on childhood TB can produce marked improvements in case detection.

Clinical standards for the dosing and management of TB drugs

BACKGROUND: Optimal drug dosing is important to ensure adequate response to treatment, prevent development of drug resistance and reduce drug toxicity. The aim of these clinical standards is to provide guidance on 'best practice´ for dosing and management of TB drugs.METHODS: A panel of 57 global experts in the fields of microbiology, pharmacology and TB care were identified; 51 participated in a Delphi process. A 5-point Likert scale was used to score draft standards. The final document represents the broad consensus and was approved by all participants.RESULTS: Six clinical standards were defined: Standard 1, defining the most appropriate initial dose for TB treatment; Standard 2, identifying patients who may be at risk of sub-optimal drug exposure; Standard 3, identifying patients at risk of developing drug-related toxicity and how best to manage this risk; Standard 4, identifying patients who can benefit from therapeutic drug monitoring (TDM); Standard 5, highlighting education and counselling that should be provided to people initiating TB treatment; and Standard 6, providing essential education for healthcare professionals. In addition, consensus research priorities were identified.CONCLUSION: This is the first consensus-based Clinical Standards for the dosing and management of TB drugs to guide clinicians and programme managers in planning and implementation of locally appropriate measures for optimal person-centred treatment to improve patient care.
