.They are U01 cooperative agreements, which means that the staff at NCI work in cooperation with the grantees. In 2000, we began with three cancer sites breast, prostate and colorectal cancerand funded 9 grants.

Besides having a breast grant of their own, their colorectal model is being used by the funded group at Memorial Sloan Kettering, and the lung model being developed at Rand is a transplanted MISCAN person.

290 ECONOMIC MODELS OF COLORECTAL CANCER SCREENING SLIDE 6 SLIDE 6 NOTES: This workshop grew out of one of the same issues that CISNET has had to address: the lack of comparability of inputs, outputs, structures and definitions among different models of the same cancer site. We have tried to address this problem in CISNET with tools called "Model Profiler," and "Base Cases." I will discuss both of these efforts.

APPENDIX Q 291 SLIDE 7 SLIDE 7 NOTES: Model Profiler is software that allows our collaborating centers to access a central CISNET interactive Web site that contains documentation on their own and other models in a consistent fashion.
|
From page 292... ...
Ideally, all collaborators would enter information into each of these documents. It is possible to go deeper and enter documents that address specific assumptions or parameters.

APPENDIX Q 293 SLIDE 9 SLIDE 9 NOTES: When each group's data is posted on the central CISNET Web site, the table of contents page looks like this.

294 ECONOMIC MODELS OF COLORECTAL CANCER SCREENING SLIDE 10 SLIDE 10 NOTES: Because each modeler answers the same set of questions, it is possible to compare the models relatively quickly. Here is an example of the Component Overview documents for a number of models.

APPENDIX Q 295 SLIDE 11 SLIDE 11 NOTES: Here is an example of an analysis on breast cancer survival, where the rows are specific models and the columns represent certain characteristics of that model. This comparative analysis is done off-line by an analyst, but it can be posted in the Model Profiler.

From page 296... ...
296 ECONOMIC MODELS OF COLORECTAL CANCER SCREENING SLIDE 12 SLIDE 12 NOTES: The final step, still to be taken, is to make the Model Profiler information available in a public site. The public site, cisnet.cancer.gov will be able to accommodate publications and documentation.
|
From page 297... ...
We have common population-based inputs, and the modelers maintain what I would call the deeper aspects of their models, e.g., assumption and formulation of natural histories. We produce a set of common computer runs, and the format of the outputs is specified.
