Definitions
Percent of people with notified drug-resistant (DR) TB (rifampicin-resistant [RR] and multidrug-resistant [MDR] TB and pre-extensively drug-resistant [pre-XDR] and extensively drug-resistant [XDR] TB) who had a contact investigation (CI) initiated.
CI initiated: For the purposes of this indicator, “initiated” refers to the process of enumeration of all known contacts to an index DR-TB case. CI will also include the evaluation of those contacts to determine if any have active TB disease or TB infection (TBI) through symptom screening, diagnostic testing, chest X-ray (CXR), or clinical evaluation.
Index case: Person with DR-TB who is notified to health authorities.
Note: This indicator is a subset of the National-Level indicator “DT_CI_INIT”.

The data sources are basic management unit TB register, CI register, laboratory register, and electronic management information systems available at the health facility and district level.
CI is important both for active case finding and TB preventive treatment (TPT). DR-TB patients should all have a CI initiated to identify additional people who may have DR-TB and reduce community spread.
This indicator provides data to identify gaps in the first step of CI service delivery, specifically to DR-TB patients.
The percent of people with DR-TB with CI initiated is calculated from the number of people with notified DR-TB who had a CI initiated divided by the total number of people with notified DR-TB. This metric provides a measure of how thoroughly programs are conducting CI activities among DR-TB patients. When analyzed over time, it can provide insights into gaps in case detection or opportunities to identify contacts that may require a TPT regimen specific for exposure to a person with DR-TB. It can be analyzed as a trend over time or between subnational units to understand contact-tracing performance trends and inform plans for scale up.
