WHO has developed two software tools for use in undertaking burden of disease analysis for regional, national or sub-national populations: DISMOD II and MODMATCH. Additional spreadsheet templates and reference tables are also available from the links aside.
DISMOD II is a software tool that may be used to check the consistency of estimates of incidence, prevalence, duration and case fatality for diseases.

Installing DISMOD II
- To install DISMOD II, unzip the file you downloaded, click on the setup.exe and follow the prompts. DisMod II consists of a single executable, and therefore can be run off a flash drive.
- DISMOD requires estimates of population structure (relative numbers of children, adults and the elderly) as well as background mortality rates. You may wish to use population and mortality data from the GBD 2004 regions or the GBD 2005 regions for your analysis.
Installing GBD 2005 regions collection
- Download the file the file GBD2004.zip, unzip it and place the GBD2004.mdb collection file in your Dismod II folder.
- Place the 17 region datasets in the Dismod II\data folder.
- Open Dismod II, and under the Data menu go to Collection, and then Add. Type GBD2004 as the name and click OK. Then find the GBD 2004 collection in your Dismod II folder.
- Once you are in the collection, it will not show any datasets until you go back and reopen the Data Collection at which point you should see the 17 epidemiological regions with their respective background mortality and population for the year 2004. Choose one and click open to start creating a disease model for that region.
User support and help
DISMOD II has an extensive help file which offers context sensitive help (click F1 or press the Help button visible on all windows). In addition, the help file contains a tutorial, a systematic description of how to navigate through and use the DISMOD II windows, and technical background information.
If you have problems using DISMOD II, please consult the tutorial and help notes. If you are unable to resolve your problem, you may send an e-mail to email@example.com for assistance.
- Windows 95, 98, NT 3.5 or 4, 2000, XP, or Vista.
- The databases are in MS Access format. The user does not need MS Access, but the connection between DISMOD and the database requires MS DAO to be installed.
- 32 MB of Random Access Memory (RAM). More RAM (64 MB minimum) is recommended for Windows NT.
- 200 megahertz processor is recommended.
- At least 50 megabytes of free hard disk space.

MODMATCH is an experimental software developed for the Stata statistical software package which can be used to generate Modified Logit system life tables based on certain inputs such as 5q0, 45q15, and e0. The Modified Logit model life table system is a 2-parameter system based on the Brass logit model and using a global standard. The system is indexed on l(5) and l(60) rather than alpha and beta as in the original Brass system. The model was developed in order to address systematic deviations in mortality patterns observed as levels of child and adult mortality deviate from the standard, and has been used extensively by WHO to produce life tables for areas with poor vital registration.
