MONITORING AND EVALUATION PLAN - TBC India

ANNEXURE B: Indicator Reference Sheet Template
Indicator TB Incidence rate
Rationale Incidence (cases arising in a given time period) gives an indication of
the burden of TB in a population, and of the size of the task faced by a
national TB control programme. Incidence is the number of new cases
arising during a defined period.
Numerator Estimated number of TB cases (all forms) occurring per year
Denominator In 100,000 population
Data collection Annually
frequency
Measurement Annual Risk of TB Infection (ARTI)
Tool
Method of
measurement
Nationwide survey of TB incidence or indirectly from measurements
of prevalence (from surveys of the prevalence of TB disease)
Interpretation The trend in TB incidence can be measured by assessing trends in case
notifications if case-finding efforts and/or recording and reporting
practices have not changed significantly. The notification rate can be a
close proxy of TB incidence where the coverage and quality of the
routine surveillance system is high.
Other relevant
information
Indicator TB prevalence rate
Rationale Indicator of burden of tuberculosis. It indicates the number of people
suffering from tuberculosis at a given point in time. It is the number of
new and previously occurring TB cases that exists at a given point in
time.
Numerator Number of bacteriologically confirmed TB cases
Denominator In 100,000 population
Data collection
frequency
Annual
Measurement Report on expert committee on TB burden based on prevalence
Tool
survey data
Method of
measurement
Measured by a population-based disease prevalence survey.
Measurements of prevalence are typically confined to the adult
