Impact Calculation Tool ICT (previously know as The Impact Calculation tool TICT) is a tool for calculating Years of Life Lost (YLL) and Years of Life lived with a Disease (YLD). By combining these two, we acquire a burden of disease estimate (BoD). This result can be used e.g. for comparing different diseases caused by various exposures. The key word is commensurable measures.

Impact Calculation Tool ICT is a tool for calculating Years of Life Lost (YLL) and Years of Life lived with a Disease (YLD). By combining these two, the model calculates a burden of disease (BoD) estimate expressed in disability adjusted lifeyears (DALY).

The tool utilizes life table approach, i.e age specific information on diseases in a given population; input data is given in 5-year categories and the model divides them evenly for the 1-year time-step used internally. ICT tool is programmed on Analytica Monte-Carlo software (Lumina, Inc., see http://www.lumina.com/). 

The model inputs include:

  • Cause of death due to exposure
  • Endpoints of morbidity
  • Population data with 5-year age intervals
  • Baseline mortality
  • Baseline morbidity
  • Exposure measure
  • Mortality exposure-response function
  • Morbidity exposure-response function
  • Duration of disease
  • Severity weights

Existing data on burden of disease can be used in the model with attributable fraction estimates.
