Brief Summary

The investigators intend to create and test an interactive prototype of an online health economic model platform, ModEx™ (renamed HModEx®), to house oncology models. The primary objective is to create the HModEx® health economic model platform. The secondary objective is to conduct usability testing of search, quality and collaboration on the HModEx® prototype for 20 oncology health economic models with expert advisory panel participants.

Outcome Measures

Primary Outcomes (1)

• Alpha testing of wireframe usability

  Iteratively unit test 4 tasks (A) Revise model platform and back end, (B) Refine the model taxonomy/characterization (i.e., ontology) and search module, (C) Revamp submission module, and (D) Implement paid modules) individually to ascertain 100% pass of common functionality (e.g., searching, uploading, and evaluating models) in the system back end and then iteratively perform integration testing via the front-end user interface until 100% pass using the System Usability Scale. The overall value of the System Usability Score ranges from 0 to 100. The higher the score on the System Usability Scale, the better.

Secondary Outcomes (1)

• Beta testing of prototype usability

  4 months

Study Arms (1)

Advisory Panelist participa will evaluate wireframes and a working prototype of the HModEx® website.

OTHER

This is a single-arm study that will build and evaluate (via usability testing) an open source health economic model platform prototype using a 9-member expert advisory panel of health economist participants from the US and Europe.
