OM2 is the new and revised version 2 of the UKPDS Outcomes Model. As with the previous version (OM1), it is based on patient-level data from the United Kingdom Prospective Diabetes Study which now extends to 30 years of followup. This computer simulation model is designed to assess the total burden of disease over an extrapolated lifetime for populations with type 2 diabetes. It uses a wide variety of input data, including knowledge of previous clinical events for individuals, and has the ability to take into account changes in some risk factor levels over time. If these updated risk factor levels are not available the model provides methods of calculating them. OM2 outputs include Estimated Life Expectancy, Quality Adjusted Life Expectancy, and costs for each member of a given population.


View the OM2 manual here.


The OM1 manual is also available here but this version of the UKPDS Outcomes Model is no longer available and will not be maintained going forward.


The UKPDS Outcomes Model can operate on Windows and Mac OS X platforms and utilise multiple cores if available. It uses Microsoft Excel workbooks to store input and output data which can be queued for processing in turn by the OM2 Controller Application which runs the model.
