Nurse-Led, Symptom-Based Screening of Household Child Contacts of Tuberculosis Index Cases (SOAR)

March 3, 2020 updated by: Johns Hopkins University
To assess implementation of a nurse-led, symptom-based screening program in local, decentralized clinics for tuberculosis (TB) screening of child contacts less than 5 years old who were exposed to tuberculosis in the home. This will allow nurses in decentralized clinics to either start IPT for those asymptomatic patients and refer symptomatic patients for evaluation of TB disease and possible antituberculous therapy (ATT).

Study Overview

Detailed Description

Retrospective review of routine program data for child contacts less than five years of adult TB index cases who are receiving TB care at local, decentralized clinics in the Matlosana district of Northwest Province will be assessed. 16 clinics will be stratified and randomized in 1:1 fashion to either TST-based screening, the current standard of care, or symptom-based screening, the newly recommended standard of care in South Africa. Those who are TST positive in the TST-based group and those who are symptomatic in the symptom-based group will be referred to Klerkdorp Hospital for further evaluation of tuberculosis. Nurses in the decentralized clinics will initiate those who are TST negative or asymptomatic on IPT. Their clinical course will be monitored throughout treatment and adherence to therapy measured. The investigators will compare clinic-level outcomes including percentage of patients initiated on, adherent to, and completing IPT.

Description

Inclusion Criteria:

  • Child less than five years old
  • Household contact of a drug-sensitive pulmonary or extrapulmonary TB index case (drug sensitivity is define as culture-confirmed OR absence of rifampin resistance on gene Xpert) admitted to one of the public clinics in the Matlosana sub-district on or after October 1, 2015.

Exclusion Criteria:

  • Household contact of a drug-resistant TB index case. (Drug resistance defined either by culture or by presence of rifampin resistance on gene Xpert).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
ACTIVE_COMPARATOR: TST-based Screening (Child contacts)
In the control clinics, decision regarding IPT will be made based on TST results, as is now the standard of care in this South African health district. In this setting, all TST negative children are initiated on IPT by the nurse at the local clinic. TST positive children are all referred to the district hospital for further evaluation of TB disease regardless of clinical symptoms. Again, clinical outcome data will be obtained from patient records and the same longitudinal child contact register.

Aim 1: Determine the number of child contacts per adult index case of tuberculosis to assess quality of contact tracing.

Aim 2: Determine the percentage of child contacts initiated on IPT or antituberculous therapy (ATT) and compare between intervention (symptom-based, nurse-led initiation of IPT) vs control clinics (TST-based screening with referral to hospital, current standard of care).

Aim 3: Compare outcomes of children initiated on IPT between both groups including: completion of therapy, discontinuation due to side effects, lost to follow up, and adherence while on therapy.

EXPERIMENTAL: Symptom -based Screening(Child Contacts)
In the intervention clinics, decisions regarding IPT will be made on a clinical basis. If the child is symptomatic, they will be referred to the hospital for further evaluation of TB disease including both chest X-ray and testing of either sputum or swallowed sputum. If the child is asymptomatic, the TB nurse at the local clinic will initiate them on weight-appropriate dosing of IPT. Children will be followed at least monthly for the duration of the six month course of isoniazid, as is standard of care in South Africa at this time. Clinical outcome data will be obtained from patient records and implementation of a contact register aimed at improving longitudinal care of children on isoniazid preventive therapy.
