Study summary

This randomized trial uses the evidence-based Systems Analysis and Improvement Approach (SAIA) adapted for tuberculosis (SAIA-TB) to assess the comprehensive tuberculosis (TB) care cascade across 16 clinics in rural Eastern Cape, South Africa to improve patient outcomes. The aims of this study are to:

  • Evaluate the effectiveness of SAIA-TB use in clinics on TB cascade outcomes for TB patients and with high-risk contacts
  • Determine the drivers of SAIA-TB implementation success or failure across clinics

The investigators hypothesize that SAIA-TB implementation will lead to a 20% increase in each of: TB screening, TB preventive treatment initiation, and TB disease treatment initiation during the 18-month intervention period.

Read the detailed description

This four-wave stepped wedge crossover cluster randomized trial will assess the effectiveness of the SAIA-TB intervention (Aim 1). A total of 16 clinics in four municipalities within the Sarah Baartman-district, Eastern Cape, South Africa will be included. The SAIA-TB intervention will be implemented at the clinic level. Public sector clinic staff and clinic managers, supported by study personnel, will deliver the intervention over an 18-month implementation phase, followed by a 12-month maintenance phase led by clinic managers without additional study personnel support, to provide evidence on intervention impact under ideal circumstances, as well as sustained effect over time. Aim 2 will consist of interviews and using the organization readiness for implementing change (ORIC) with facilities early in SAIA-TB implementation (within 3 months of initiating the intervention) to identify clinic-level attributes that affect intervention adoption. Additionally, the Consolidated Framework for Implementation Research (CFIR) will guide data collection and interpretation related to implementation, assess fidelity to intervention protocol, describe intervention adaptations when integrated into routine management systems, and identify clinic-level determinants of successful SAIA-TB implementation. Recurrent measurement of structural readiness and implementation dose (as a function of quality and quantity) at the clinic level will inform guidance on essential structural needs to implement SAIA-TB. The trial will culminate in a dissemination package, summarizing results and providing implementation guidance to support scale-up.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Other
    Exposed

    Clinics are considered exposed after intensive SAIA-TB intervention, implementation phase, and maintenance phase.

  • No intervention
    Unexposed

    Clinics are considered unexposed prior to the initiation of SAIA-TB in their clinic

Interventions

  • OtherSystems Analysis and Improvement Approach for TB (SAIA-TB)

    The Systems Analysis and Improvement Approach for TB (SAIA-TB) is a five-step systems analysis and iterative improvement cycle intervention which will be implemented by clinic staff with support from study personnel in intervention clinics. Components of the intervention include TB cascade analysis, patient flow mapping and continuous quality improvement, aimed to incrementally optimize TB screening, evaluation, diagnosis, TB preventive therapy and TB disease treatment initiation, successful treatment, and TB-free survival among the population at the intervention clinics.
