  • Where Do We Use Real Health Information? Clinicians who are treating their patients need real information Every patients health information should be quickly retrievable by anyone authorized to be involved in that patients care (especially if the patient is unconscious or unable to do so themselves) Researchers who are attempting to discover something new need real information but they keep it behind closed doors to prevent unauthorized disclosure Systems that integrate electronic medical record systems so that health information can be quickly shared through interoperable statewide and national networks need real information But not the people who develop them or operate them Copyright 2014,2015 MiHIN Shared Services.

  • Why Use Synthetic Health Information? Some types of data that we share statewide involve millions of messages per week just in Michigan Significant risk of unintentional disclosure of real health information Testing system interoperability with real health data is high risk due to possible disclosure of information protected by federal laws on privacy Especially for information about behavioral health, certain diseases, or substance use Real health data cannot easily be fully de-identified Good, realistic test data is practically never available in healthcare today Major risk is wrong people seeing someones protected health information Software developers, systems integrators & testers need to view test data to do their jobs Test data could be sent to the wrong recipient(s) in high volumes Risks are much higher during development and testing than any other time Dozens of new use cases are waiting to be developed and tested Copyright 2014,2015 MiHIN Shared Services.

  • PatientGen The Goal Advance ability to automatically create large quantities of realistic health data that is not protected or private Accelerate efforts to deploy interoperable healthcare systems using realistic data for development, testing, and successful deployment of data sharing use cases Provide general purpose ability to create a wide variety of safe test data for use cases ranging from: Public health reporting (e.g. immunizations, syndromics, reportable labs, cancer/birth defect/death notifications) Transitions of care (admission-discharge-transfers, medication reconciliations) Clinical quality measures (CQMs) Accelerate the transformation from volume-based to quality- based healthcare delivery and payment.

  • Clinical Possibility Constraints Key ElementsDescription Sequence Episodes of care have a beginning and an end. Events occur in a specific order (e.g. patient experiences chest pain, before diagnosed of heart attack, before angioplasty is performed). Duration Activities span typical lengths of time which can be represented as a minimum and maximum, or average duration (e.g. an angioplasty procedure takes 60-90 min). Role-Activity Association Activities may be constrained to a specific role, via regulation or policy (e.g. diagnoses are made by physicians, advanced practice nurses, or physician assistants). Range Activities and events can be associated with rules or parameters (e.g. drugs have associated dosage ranges, etc.). Mutual Exclusivity An event may not be permitted or plausible within the presence of another event. Likelihood of Occurrence Events are associated with an expected frequency (e.g. infants born full term have a high chance of survival, patients admitted for a traumatic injury are unlikely to be admitted against their will, etc.) Metadata Activities or events may produce, or may require specific information as metadata (e.g. patients have an associated age, gender & race).

  • Simulation Goals & Clinical Relevance Simulation produces a full longitudinal record Clinical relevance is expanded even further, to cover a patients lifetime (e.g. natural disease clusters) Represent a patients lifetime Simulation produces a full record for an episode of care Clinical relevance is applicable to many more aspects of care (e.g. what happened before and after the PCI at 90 minutes) Represent a full episode of care Simulation produces only data elements required for quality measurement Clinical relevance is limited to clinical quality measure data Test Software Copyright 2014,2015 MiHIN Shared Services.

  • Signs and Risks Affect Body Systems Copyright 2014,2015 MiHIN Shared Services. MiHIN Confidential Proprietary Restricted Body Signs Measurable values that have trajectories over patient lifetimes e.g. blood pressure, HbA1c, BMI, Cholesterol Signs can represent chronic conditions such as hypertension, diabetes, obesity, hyperlipidemia Quantized & normalized using Likert scales (1-5) Initial values drawn from configurable prevalence data Risk Factors Patients have risk factors such as smoking, diet, alcohol use, drug use, promiscuity Risks can affect the trajectories of signs & the likelihoods of complications Patient risks initially drawn from configurable prevalence data As patients age, they acquire risks drawn from incidence data

  • Patient State Drives Diagnoses & Encounters Copyright 2014,2015 MiHIN Shared Services. MiHIN Confidential Proprietary Restricted Diagnoses (CQM measure diagnoses) Patient state is calculated based upon systems, risks & signs Incidence & prevalence likelihoods based upon published medical studies and experience (e.g. Framingham) System health state changes drive diagnosis and encounters Most likely diagnosis can be computed from risks & signs when not specified by organ, system or risk logic Quality Measures Sampled from most likely diagnosis measures Drive patient encounters via scripted CAT-I event sequences embodying clinical knowledge Patient Encounters Produce CQM reports, ADT events & ACRS Care Teams Outcomes can influence signs & risks to close the feedback loop and improve longitudinal histories

  • The Open Source Option Is Under Consideration Open Source means more hands, eyes and energy to improve quality & advance PatientGen capabilities across multiple fronts Open Source means more organizations can benefit from simulated healthcare data We favor Apache-style meritocracy for organization & team roles Successful open source projects require continuity of leadership and direction MiHIN is seeking external funding sources to provide this leadership Copyright 2014,2015 MiHIN Shared Services.
