N241-002 TITLE: Medical Echelon of Care Conceptual Models for Wargaming

OUSD (R&E) CRITICAL TECHNOLOGY AREA(S): Advanced Computing and Software

OBJECTIVE: Develop Medical Echelon of Care models for wargaming, sufficient to withstand review board scrutiny to support model verification, validation, and accreditation, as required. The focus is on developing and implementing the models referenced herein, not on the underlying mechanics of the Program Manager Wargaming Capability (PM WGC) materiel solution simulation framework.

DESCRIPTION: This SBIR topic addresses two parametrics of interest for future inclusion in the Neller Wargaming and Analysis Center (NWAC), formerly the Marine Corps Wargaming and Analysis Center (MCWAC). Both parametrics are related to medical echelon of care. In the table below, the two major parametrics considered are "Echelon of care" and "Time requirements between echelons of care". The specific conceptual model requirements are listed for each parametric.

The purpose of the models is to support realistic evaluation of medical support systems within USMC future concept and capability development and Operational Plan assessment wargames. The prototype would provide medical treatment simulation from time of injury to return to combat effectiveness via the various echelons of care.

Some examples under the above headings include, but are not limited to:

- Establish baseline performance characteristics of existing medical support systems under a given scenario.

- Model novel ways of treating/transporting/managing Marine casualties occurring in austere environments within challenging operating environments, with imposed limitations on naval medical support.

- Model the complex relationships between location and type of injury, types of medical transport available, location and capabilities of the various echelons of care available, eventual return to combat effectiveness, and associated critical time and resource metrics.

Full satisfaction of each conceptual model requirement is the end goal, however partial solutions will be considered. This topic specifically focuses on developing the mathematical, algorithmic, and data aspects of the conceptual models. The mechanism by which these conceptual models would be integrated with existing wargaming kinetic models resident within the NWAC is not the focus. Documentation of the conceptual models with Cameo Systems Modeler (Cameo/SysML) is desirable, but not necessarily a strict requirement, if another representation is more suitable [Ref 2].

PHASE I: Develop concepts for an improved representation of medical echelon of care in wargaming M&S that meets the requirements described above. Demonstrate the feasibility of the concepts in meeting Marine Corps needs and establish that the concepts can be developed into a useful product for the Marine Corps. Feasibility will be established by evaluation of the plan of attack for the development effort including data availability. Provide a Phase II development plan with performance goals and key technical milestones, and that addresses technical risk reduction.

PHASE II: Develop prototype conceptual models. The prototype will be evaluated to determine its capability in meeting the performance goals defined in the Phase II development plan and the Marine Corps requirements for medical echelon of care M&S. System performance will be demonstrated through prototype evaluation over the required range of parameters. Evaluation results will be used to refine the prototype into an initial design that will meet Marine Corps requirements. Prepare a Phase III development plan to transition the technology to Marine Corps use.

PHASE III DUAL USE APPLICATIONS: Support the Marine Corps in transitioning the technology for Marine Corps use. Develop medical echelon of care conceptual models for evaluation to determine effectiveness in an operationally relevant environment within the NWAC. Support the Marine Corps for M&S Verification, Validation, and Accreditation (VV&A) to certify and qualify the system for Marine Corps use.

The conceptual models described herein are not only a high priority within the Marine Corps [Refs 1, 3], but are equally applicable across the Services, to support not only wargaming, but also analysis, training, and experimentation. Successfully developed conceptual models would likely be of great interest across these communities. DoD components and prime contractors are in need of accurate medical casualty/echelon of care simulation representation to support gap analysis and solution assessment. Potential civilian applications include emergency medicine and care after the emergency room.

Topic Q & A

12/13/23  Q. For model requirements like L34, "Modify casualty survival rate based on trauma team actions", where would the numbers for things like infection chance be sourced? In recreational games with low level medical simulation (i.e. Dwarf Fortress), it's an arbitrary combination of wound type, treatment type, medical personnel skill level, genetic variation, environment, etc. Would the numbers be tweaked by end users based on simulation intent, or would they be fixed approximations based on publicly available medical research?
   A. The data feeding the conceptual models desribed in this topic should be the best available, whether from public sources, DoD holdings, or otherwise. Part of the effort therefore is to determine what sources of data are available and in the case where multiple sources are available, recommend which sources offer higher accuracy. It is possible as well that for a particular wargame, the planners would modify some parameter in order to approximate some hypothesized future conditions.
