Vedtakelse av innovative tilnærminger for å sikre kontinuitet i TB-tjenester av høy kvalitet under Covid-19-pandemien i Lusaka og Livingstone, Zambia. (Telemedisin i TB) (Telemed TB)

25. september 2026 oppdatert av: Centre for Infectious Disease Research in Zambia

Following the negative impact of public health program services including TB services by the COVID-19 Pandemic in 2020, CIDRZ conducted a program evaluation for remote patient follow up for TB treatment and prevention through a differentiated service delivery model (DSD), offering clinical monitoring and psychosocial support while minimizing contact with the health facilities. The project was implemented between February 2022 to March 2023 and was funded through Centers for Disease Control and Prevention's COVID-19 Response International Task Force - CARES funding. While DSD models have been widely adopted in HIV programs , DSD is a relatively new and exciting approach for TB treatment and prevention programs.

Detaljert beskrivelse

During the COVID-19 pandemic, government restrictions on movement decreased access to health care. Although DSD models have been widely adopted in HIV programs, this is a relatively new approach for TB programs. Zambia's NTLP has already changed policy to allow for such adaptations of service delivery, but these adaptations are not universally implemented and have not been evaluated at this time. This project aims to evaluate these DSD models for both TB treatment (Anti-TB Treatment ATT) and TPT using standardized indicators. To complement these DSD models, innovative approaches like digital (texting/SMS and phone) treatment support and remote monitoring of adverse events will be adopted using bi-directional SMS through use of the rapid pro system, a tool that allows medical information to be gathered and shared via a cell phone.

  1. To implement TPT in 6MMD and ATT DSD models at 5 sites in Lusaka and Livingstone districts
  2. To assess acceptability of TPT in 6MMD and ATT DSD models at implementation sties
  3. To assess trends in TPT coverage and completion rates from pre-implementation through implementation periods using aggregate program performance data
  4. To assess trends in ATT completion rates from pre-implementation through implementation periods using aggregate program performance data
  5. To inform the Ministry of Health on a systematic approach for digital follow up and screening for TB and TPT RoCs aligned to MMD models of care.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Aktiv komparator: TB treatment ARM

Beginning February 2022, we offered ATT via 2-month MMD during intensive and 4-month MMD during continuation phases.

In-clinic visits during 6-months of ATT were reduced from 7 under standard of care to 3 visits in DSD, while ensuring robust adherence and adverse event screening.

Remote monitoring consisted of structured SMS (months 1 to 5) and phone (week 2 and month 3) follow-up to assess adherence and screen for side effects. If SMS were not returned, a phone or home visit was triggered.

Although DSD models have been widely adopted in HIV programs, DSD is a relatively new approach for TB programs because of an historical reliance on directly observed therapy (DOT) (6). DSD provides opportunities to improve health outcomes and reduce the burden of seeking care for people diagnosed with TB.

Aktiv komparator: TPT DSD

Beginning February 2022, we offered TPT aligned to 6MMD ART model following standard of care processes with added support (See below).

Remote monitoring consisted of structured SMS (months 1 to 5) and phone (week 2 and month 3) follow-up to assess adherence and screen for side effects.

ROCs that did not respond to the SMS within 2 days were further contacted via phone and if not reachable a home visit was done.

ROCs that reported at least one side effect or more were followed up with virtual reviews by clinicians.

At enrollment ROCs reading language of preference was documented and the SMS was sent in their preferred language.
