Modex, a Cloud-based, Centralized Health Economic Model Marketplace to Reduce Costs and Enhance Equity in Cancer

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.

About this study

Primary Endpoint: 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 (as below). The System Usability Scale yields a single number representing a composite measure of the overall usability of the system being studied. To calculate the System Usability Scale score, first sum the score contributions from each item. Each item's score contribution will range from 0 to 4. For items 1,3,5,7, and 9 the score contribution is the scale position minus 1. For items 2,4,6,8 and 10, the contribution is 5 minus the scale position. Multiply the sum of the scores by 2.5 to obtain the overall value of System Usability Score; scores range from 0 to 100, with higher numbers being better.

Secondary Endpoints: Measure the success of Aim 2 by (1) completion of 80% of tasks in usability testing with scores of ≥68 on the System Usability Scale, a validated questionnaire, and (2) satisfaction with the site. Testing will focus on user interaction with the system, emphasizing effectiveness, efficiency, engagingness, error tolerance, and ease of learning. Specifically, the investigators will assess the ability of the project team and Advisory Panel member participants to log into the platform, configure and manage their modeling projects, and annotate or categorize them in accordance with an ontological index. The investigators will assign participants to interact with at least 2 randomly selected models and associated data files, iterating on this milestone until the investigators achieve 100% success.

Primary outcomes

  1. Alpha testing of wireframe usability

    Time frame: 2 months

    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

    Time frame: 4 months

    Measure the success of Aim 2 by (1) completion of 80% of tasks in usability testing with scores of ≥68 on the System Usability Scale, a validated questionnaire, and (2) satisfaction with the site. Testing will focus on user interaction with the system, emphasizing effectiveness, efficiency, engagingness, error tolerance, and ease of learning. Specifically, the investigators will assess the ability of the project team and Advisory Panel member participants to log into the platform, configure and manage their modeling projects, and annotate or categorize them in accordance with an ontological index. The investigators will assign panelist participants to interact with at least 2 randomly selected models and associated data files, iterating on this milestone until the investigators achieve 100% success. The overall value of the System Usability Score ranges from 0 to 100. The higher the score on the System Usability Scale, the better.
