Key driving forces in health informatics

Information is what our world runs on. Man has evolved from the food-gatherer to the information gatherer. Information pervades science from top to bottom, transforming every branch of knowledge.

Marshall McLuhan, 1967


Key driving forces in health informatics

Our age is the Information Age – younger than some of us. Claude Shannon created that age in 1948 when he made information a science; he gave it a definition; he gave it units of measurement – the bit. Shannon estimated the digital information in a text, a photograph, a record, and even in the Library of Congress.

Meaningful use

Meaningful Use

  • In 2008, the National Priorities Partnership, convened by the National Quality Forum (NQF), released a report entitled “National Priorities and Goals” which identified a set of national priorities to help focus performance improvement efforts.

  • Among these priorities were patient engagement, reduction of racial disparities, improved safety, increased efficiency, coordination of care, and improved population health.

  • These priorities have been used to create the framework for “Meaningful Use” of an electronic health record system

  • The ultimate goal of Meaningful Use of an Electronic Health Record is to enable significant and measurable improvements in population health through a transformed health care delivery system

2010s 100 petabytes

2010s – 100 Petabytes

Is Facebook’s data hoard bigger than Google’s today? Some say yes, some say no. According to Facebook, its user content makes up more than 100 petabytes of stored photos and video. And analyzing that data generates about 500 terabytes of new information every day – more than 2 ½ times the size of a ‘90s Wal-Mart data cache.

Genetics

Genetics

  • Gene mutation will identify many treatable genes such as Hirschsprung’s disease, muscular dystrophy, and cystic fibrosis

  • Drug treatments are already influenced by genomic information

    • The anticoagulant drug warfarin has a narrow therapeutic window - too high a dose, patient can bleed to death; too low a dose, clots remain unclotted. Genetic information [certain versions of two genes CYP2C9 and VKORC1] are highly predictive of rate of metabolizing warfarin.


Clinical research informatics

Clinical Research Informatics

  • Registries, controlled data exchange among researchers, provenance, data capture tools such as REDCap, query tools such as i2b2, analytics tools, management of clinical trials

  • Patient care – continuing use of patient care data, shared collection of data, cohort identification, discovery of target drug requirements, early translation of research into routine patient care

  • Population Health – understanding of prevalence of disease, identification of new drug targets


Patient care informatics

Patient Care Informatics

  • Meaningful use of data, EHR systems, data exchange, decision support, supporting safe and high quality health care effectively and efficiently at best cost, interoperability among all sites of care, embracing preventive and personalized care, clinical data warehouses, creation of new knowledge, supporting patient-centric EHRs

  • Adverse events fed back to clinical research and ‘omics research


Public health informatics

Public Health Informatics

  • Acquisition of data and structured reports, tracking of disease outbreaks, control of epidemics, insuring appropriate immunization and vaccinations, analytics, infectious disease control, disaster management

  • Patient care – source of data from health surveillance and disease management


Key driving forces in health informatics

EHR

  • New types of data

    • Genomic

    • Image

    • Waveform

    • Patient-generated

    • Video

    • Environmental

    • Behavioral

  • Within the next 5 years, over 50% of the data contained in a patient’s EHR will be non-clinical.


Predictions for the next decade

Predictions for the next decade

  • We will discover a genetic linkage to most diseases

  • Early discovery of disease-causing mutations will influence care with better outcomes

  • Cost of DNA sequencing will drop to $500 or less

  • Children will have their DNA sequenced at birth

  • Most adults will have their DNA sequenced

  • Genomic data coupled with personal health data will have a strong impact on the pharmaceutical industry. Drugs will be more targeted.

  • Health care model will change as will the role of the provider


Challenges

Challenges

  • Acceptance that cooperation and sharing is a win-win situation

  • Single ontology that links all domains; that is an open process; that uses a common process in which expertise is the dominant factor; identifies stewardship of each ontological term

  • Ontology removes all ambiguity in associated attributes; ontology matches terms that are used in the process of research and care


Challenges1

Challenges

  • Solves privacy issues; recognizes that personal control of data may harm creation of new knowledge and seamlessly connecting the contributing domains for the most effective care

  • Identification and implementation of standards for data and data exchange

  • Controlled and purposeful exchange of data

  • Quality of data is insured through process, algorithms, and certainty factor

  • Improve techniques for the management and use of data (MU)

  • Educate people in the need for and use of informatics (HITECH, incentive funding)

  • Ethics, privacy, security (HIPAA)


What is gis

What is GIS?

  • A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.

  • GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, reports, and charts.

  • Ultimately helps answer questions and solve problems by allowing us to look at our data in a way that is quickly understood and easily shared.
