Name TB Mortality rate (Deaths from TB given year per 100,000 population) (MDG 6.9.2)
Definition The tuberculosis death rate indicator refers to the estimated number of deaths due to tuberculosis (TB) in a given time period per 100,000 population
Calculation/Formula Deaths due to TB (underlying cause according to ICD rules) divided by total population. Estimates of TB mortality are based on a consultative and analytical process led by WHO. Vital registration data are used where available.
Assumptions Country-specific estimates of TB mortality are, in most instances, derived from estimates of incidence (for additional details, please refer to the TB incidence indicator metadata), combined with assumptions about the case fatality rate. The case fatality rate is assumed to vary according to whether the individual receives treatment in a DOTS programme or not, and whether the individual is infected with HIV. The TB mortality rate is calculated from the product of incidence and case fatality (proportion of incident cases that ever die from TB).
Limitations TB mortality can be measured directly only where there is a good vital registration system, with accurate coding of cause-of-death. The number of patients dying while on TB treatment (as reported in routine follow-up of cohorts of TB patients) is not an indication of true TB mortality, as it includes deaths from causes other than TB, excludes deaths from TB among people not on treatment, and excludes deaths among people that are treated for TB but who are not registered in routine TB surveillance systems. Reliable figures require that death registration be nearly universal and that the cause of death be reported routinely on the death records and determined by a qualified observer according to the International Classification of Diseases. Such information is generally not available in developing counties. Vital statistics registration systems tend to underestimate tuberculosis deaths, although time series data from some countries in Asia and America give a useful indication of trends. In the absence of direct measures of prevalence and death rates, a variety of techniques can be used to estimate these values. Administrative data are derived from the administration of health services. Data can also be obtained from household surveys such as the Multiple Indicator Cluster Surveys (MICS) or the Demographic Health Surveys, although they usually refer only to children under five or provide death rates
Purpose/Rationale To reduce TB related morbidity, achieve Stop TB Partnership targets and contribute towards the achievement of the Millennium Development Goals - Internationally recommended impact indicator, with international targets; The international target is to eliminate TB as a public health problem (i.e. an incidence rate of less than one case of TB per one million population) by the year 2050; The regional target is to eliminate TB as a public health problem (i.e. an incidence rate of less than one case of TB per one million population)

Preferred Data Sources The primary source of cause-specific mortality data should be vital registration including Cause of death data collected through the health dept and/or civil registry and verified for completeness
Primary Data Collection System National Administrative Database - Health Information Management Systems (HIS)
Frequency of Data Collection Annual (aggregated over multiple years)
Other agencies countries_ must report to: CHIPS, Global Fund
SPC Responsibility - Data Management SDP
Comments / Regional Trend Analysis As countries improve vital statistics and civil registration systems, there may be some increases in published measures of mortality (such as IMR) due to improvements in reporting rather than a true increase in mortality rate. Care must be taken in inter
