Study summary

The overall objective of this study is to determine if a multi-component implementation intervention (SPIRIT) and additional leadership and management training that targets District Health Officers (DHOs) can increase IPT initiation among HIV-infected persons, as compared to country standard practices, in a cluster randomized trial in Uganda.

Read the detailed description

The failure to use isoniazid (INH) preventative therapy (IPT) in HIV-infected individuals in Sub-Saharan Africa represents one of the single biggest implementation gaps between evidence and practice in today's response to the HIV epidemic. The proposed study will evaluate the effectiveness of a multi-component intervention to improve IPT uptake in two regions of Uganda. The study design is a randomized controlled trial (RCT) where the unit of randomization is clusters of districts in Uganda. The clusters consist of 5-7 districts and the District Health Officer (DHO) and District TB and Leprosy Supervisor (DTLS) from each district is invited to participate. The SPIRIT intervention is based on the PRECEDE framework which outlines the importance of social networks, social influence, and behavior change.

The SEARCH-IPT multi-component intervention includes:

  • A teaching collaborative which will be formed within the randomized clusters of district DHOs and DTLSs to create a mini-collaborative, which will be led by an opinion leader with HIV and TB expertise, to spread new scientific knowledge about IPT and the clinical ability to rule out TB, and to facilitate discussion between DHOs.
  • A "toolkit" of options to ease IPT implementation will support DHOs to scale up IPT through the study of the comparative effectiveness of material contributions to their day-to-day function of managing front line providers and clinics.
  • A reporting collaborative comprised of the teaching collaborative groups, will define targets as a group, and reconvening every 6 months for 3 years (with the additional option of 36 months for a final report back), where each collaborative has an opportunity to share progress and results.

In addition, an enhanced business training \& 'training-of-trainers' curriculum will be conducted to evaluate the effect of enhanced business training among intervention group DHOs from Phase 1 (Years 1-3 of trial follow-up) in the southwestern Uganda region on IPT initiation during years 4-5 of trial follow-up (Phase 2).

Study arms

  • Experimental
    Aim 1: DHO Intervention Arm

    A selection of DHO or TB district supervisors that are randomized to the multicomponent SPIRIT intervention.

    Behavioral: SPIRIT Intervention

  • No intervention
    Aim 1: DHO Control Arm

    A selection of DHO or TB district supervisors that are randomized to the country standard of care, but not to receive the study intervention.

Interventions

  • BehavioralSPIRIT Intervention

    The intervention will include implementing a teaching collaborative among group of DHOs and TB Supervisors, enabling text messaging between DHOs and front line providers, and establishing a report collaborative where DHOs will receive feedback on the performance of their district in administering IPT compared to other districts.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2017 to primary completion in Nov 2023, 72 months.

Results were first posted in Jun 2025, 1 year 6 months after primary completion.

Of 169 non-industry interventional studies with no phase under Tuberculosis, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 41. This study's 72 months is above that.

Counting every sponsor, half of 171 studies reached it within 25 months; a quarter within 14 and three quarters within 41.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 18, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
