IID-31 Increase the percentage of contacts to sputum smear-positive tuberculosis cases who complete treatment after being diagnosed with latent tuberculosis infection (LTBI) and initiated treatment for LTBI

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
Aggregate Reports for Tuberculosis Program Evaluation; Centers for Disease Control and Prevention, National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (CDC/NCHHSTP)
Changed Since the Healthy People 2020 Launch: 
Yes
Measure: 
percent
Baseline (Year): 
68.1 (2007)
Target: 
79.0
Target-Setting Method: 
Maintain consistency with national programs, regulations, policies, and laws.
Target-Setting Method Justification: 
The target is aligned with the National TB Indicator Project objectives. The algorithms for calculating the indicators for these objectives were standardized through consensus among stakeholder representatives from TB programs and laboratories at the state and local level. Targets were derived from recent results of programs ranked at the 90th percentile for the respective performance indicators.
Numerator: 

Number of persons completing treatment for latent tuberculosis infection (LTBI) who, during the contact investigations of AFB sputum-smear positive TB cases, have been found to have LTBI and initiated treatment

Denominator: 

Number of persons who, during the contact investigations of AFB sputum-smear positive TB cases, have been found to have LTBI and initiated treatment

Comparable Healthy People 2010 Objective: 
Retained from HP2010 objective
Data Collection Frequency: 
Annual
Methodology Notes: 

    Treatment for latent TB infection substantially reduces the risk that TB infection will progress to disease. Certain groups are at very high risk of developing TB disease if infected. Identifiable population groups at high risk for TB vary in time and geographic area, depending on unique and changing TB related demographics.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
In 2013, the original baseline estimate was revised from 64.3% (2007) to 68.1% (2007). The former estimate was submitted as preliminary data. The latter estimate reflects the final national estimate. The target was not revised. In 2013, the phrase "and initiated treatment" was added to the numerator and denominator for clarity because not everyone with LTBI actually starts treatment. In 2013, the objective statement was revised for clarity from "Increase the percentage of contact to sputum smear-positive cases who complete treatment after being diagnosed with latent tuberculosis infection" to "Increase the percentage of contacts to sputum smear-positive tuberculosis cases who complete treatment after being diagnosed with latent tuberculosis infection (LTBI) and initiated treatment for LTBI."
