Scenario

CMO goals of care

CDSS assistance

Rationale

Any Medical event

Automation of information flow between vehicle and MCC

Collect, collate and communicate with MCC

Reduce operator time and cognitive load.

Emergency

e.g., Cardiac arrest, unexpected life threats

Delayed comms to MCC makes this a priority

• Stabilize patient to allow time for full analysis by CDSS, crew, and ground teams and allow further complex treatment

• Reduce crew workload

• Perform procedures correctly

• Acquire and comprehend data from multiple sources

• Easy to access and follow protocols

• Prioritized and clutter-free essential information

• Electronic procedures;

• Just in Time Training

• Vital signsa collection and display

• Predetermined protocols for fast-paced, life-threatening scenarios, e.g., ABCDE32.

• Assist with procedures as required. e.g., intubation

• Feedback on success of treatment to inform next step in protocol

Routine – Diagnosis

e.g., Headache, Lower back pain

Problematic communication delay between each question and answer during a PMC with Earth

• Assess severity

• Perform a differential diagnosis

• Determine highest probability condition

• Supports clinical workflow

• Dynamically adjusts to novice or expert user

• Probabilistic engine calculates next best question with highest positive predictive value

• Diagnosis is a complex task

• System should support caregiver’s mental model

Routine - Treatment

e.g., Headache, Lower back pain

Delayed comms make this problematic

• Treatment and care plan

• Treat with best practice and minimal use of resources

• Manage medications

• Manage patient records

• Ensure tailored, precision-based medicine

• Facilitate efficient and prompt care

• Therapeutic advice based on evidence with ranked options crew can choose from.

• Offer a variety of pharmacologic and alternative treatments

• Automatic patient record retrieval including allergies, existing treatment and conditions

• Provide information on stowage location of medications, supplies, equipment

• A large knowledge base in CDSS is required to give all possible options (e.g. Merck manual5) supplied as needed based on diagnosis

• Crew personal preferences

• Medical errors can easily be mitigated with automatic record retrieval and checking

• A simple and extremely valuable task in a space vehicle full of equipment

• Trade-off side effects or performance deficits

• Options dependent upon limited supply

Routine - Observation

Rich data best analyzed on vehicle due to low transmission bandwidth

Prompt response to emerging issue

• Assess initial care plan effectiveness

• Recognize change in status to higher or lower acuity and adapt plan as needed

• Update previous decisions based on new observations

• Clinical practice treats ‘most likely/severe diagnosis.’ New or persistent symptoms can offer information for new diagnosis or change to emergency scenario

Prevention

e.g., Kidney Stones

Rich datasets created on vehicle best residing locally due to narrow comms bandwidth

• Anticipate threats to health to reduce medical events over time

• Mitigation strategies to enhance and/or prevent decrements in performance

• Measure the crew with least possible distractions to operational activities

• Accurately record data in medical records

• Prediction of performance decrements or potential medical events

• Ambient Monitoring33

• Automated record keeping

• Long term issues such as kidney stones, bone loss, behavioral and cognitive deficits can be mitigated with diet, sleep, exercise

• Ambient monitoring data collection and analysis reduces workload
