A field with supporters in high places

“To improve the quality of our health care

while lowering its cost, we will make the

immediate investments necessary to ensure

that within five years, all of America’s

medical records are computerized … It just

won’t save billions of dollars and thousands

of jobs – it will save lives by reducing the

deadly but preventable medical errors that

pervade our health care system.”

- January, 2009

Health Information Technology for Economic

and Clinical Health (HITECH) Act of American

Recovery and Reinvestment Act (ARRA) of

2009 invested up to $30 billion in health

information technology3

Opportunities are not limited to

healthcare

“Modern biomedical scientists use computers and

robots to separate molecules in solution, read

genetic information, reveal the three-dimensional

shapes of natural molecules like proteins, and take

pictures of the brain in action. All of these

techniques generate large amounts of data, and

biology is changing fast into a science of

information management. There is no way to

manage these data by hand. What researchers

need are computer programs and other tools to

evaluate, combine, and visualize these data.”

Other areas of opportunity

• Public health – protecting the public and promoting health– e.g., disease surveillance, such as for H1N1 or

bioterrorism

• Consumer health – enabling better management of health– Personal health records for engaged patients and

consumers

• Imaging – use of images and their analysis for biomedical research and clinical care

• And more…

What is biomedical and health

informatics?

• I get asked this so often that I keep a Web site

– http://www.billhersh.info/whatis/

• I have also written about it

– Overview of “medical informatics” (Hersh, 2002)

– But there are barriers (Hersh, 2004)

– Characterization of and changes in the profession (Hersh, 2006)

– Many career opportunities as well (Hersh, 2008)

– Definitions of field (Hersh, 2009)

– Workforce needs (Hersh, 2010)

Page 8: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Let us start by defining “informatics”

• Field concerned with how people use information, usually aided by technology, to improve aspects of the world

• More about information than technology, but technology is essential

• “The science of health service design must be a science of sociotechnical systems, and today that science is called informatics.” (Coiera, 2007)

(SUNY Buffalo)

Page 9: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

It has a “fundamental theorem”

(Friedman, 2009)

Goal of informatics is:

and not:

Page 10: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

My current preferred terminology

(Hersh, 2009)• Biomedical and health informatics (BMHI) is the field

concerned with the optimal use of information, often aided by technology, to improve individual health, healthcare, public health, and biomedical research– Differs from information technology (IT) in that

• Is strongly rooted in domains (e.g., health)

• IT is one (of many) tools employed

• Practitioners of BMHI are usually called informaticians(sometimes informaticists)

• Disagreements over terminology in both noun and adjectives preceding it– Has an “adjective problem”

10

Categories of BMHI (cont.)

• Bioinformatics – application of informatics in cellular and molecular biology, often with focus on genomics

• Medical/clinical informatics – application of informatics to individuals– Informatics applied in a more specific healthcare domain is

{X} informatics, e.g., nursing, dental, pathology, primary care, etc.

• Public health informatics – application of informatics in public health

• Over-arching aspects of BMHI– Imaging informatics – focus on images in all categories

– Research informatics – focus on research in all categories

12

Page 13: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Informatics now viewed as a core

competency for health professionals• According to Institute of

Medicine report, the modern health professional must have competency in informatics as part of larger goal to provide patient-centered care (Greiner, 2003)

• Informatics competency is not just computer literacy!– The “Google generation” (aka,

“digital natives”) does not necessarily have good information skills (CIBER, 2008)

13

Page 14: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Some historical perspective on

informatics (Collen, 1994)

• Origin of term from Russia in late 1960s

• Achieved widespread use in France (informatique) and later rest of Europe in 1960s to denote computing issues related to information use– “Medical informatics” first used in 1974

– European perspective documented by Hasman (1996) and Moehr (2004)

• At present, most significant use is in biomedical arena, but it is used by other domains, such as law, chemistry, social sciences, etc.

14

Page 15: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

How is informatics distinguished from

related terms?

• Information technology (IT) – computer and related technology

• Health information technology (HIT) – health-related application of IT

• Computer science (CS) is academic discipline that underlies IT (and other technologies)

• Management information systems (MIS) is another field underlying IT (usually in business schools)

15

Page 16: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Other related terms

• Health information management (HIM) –discipline historically focused on management of (paper) medical records (changing in current environment), with three main levels of practice

– Registered Health Information Administrator (RHIA) –highest level, baccalaureate degree

– Registered Health Information Technologist (RHIT) –associate degree

– Certified Coding Specialist (CCS) – usually less then associate degree

16

Page 17: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Other related terms

• Information and communications technology (ICT) – same as IT with added emphasis on telecommunications

• eHealth – use of ICT for health

• Telemedicine – provision of healthcare when participants separated by time and/or distance

– Sometimes applied in specific clinical specialties, e.g., teleradiology, teledermatology

• Telehealth – pursuit of health when separated by time and/or distance

17

Page 18: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Other related terms

• Evidence-based medicine (EBM) – the application of the best scientific evidence in the medical decision-making process

• Evidence-based practice (EBP) – the application of EBM in medical practice

• Comparative effectiveness research (CER) – research that compares one or more diagnostic or treatment options to evaluate effectiveness, safety, or outcomes

• Information retrieval – the field devoted to searching (mostly text, mostly knowledge-based information)

18

Page 19: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Other terms central to medical/clinical

informatics• Electronic health record (EHR) – patient’s health record in

digital form– Has mostly supplanted the term electronic medical record (EMR)

• Personal health record (PHR) – personally controlled health record, which may or may not be tethered to a healthcare organization’s EHR

• Health information exchange (HIE) – exchange of health information across traditional business and other boundaries– Organization managing HIE used to be called a Regional Health

Information Organization (RHIO)

• HITECH Act introduced a new type of organization –Regional Extension Center (REC)

19

Page 20: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Other terms related to the EHR

• Clinical decision support (CDS) – alerts,

reminders, rules designed to improve clinician

decision-making

• Computerized physician/provider order entry

(CPOE) – with or without CDS

• Interoperability and standards

• Privacy, confidentiality, and security

20

Page 21: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Research informatics

• Clinical research informatics (CRI) is area of informatics applied to clinical research (Embi, 2009)

• Increasing recognition that research findings must “translate” into clinical care more quickly and efficiently, leading to NIH investment in clinical and translational research through the Clinical & Translational Science Award (CTSA) program (Zerhouni, 2007)– Difference between IT and informatics very evident in this

domain (Bernstam, 2009)

• Translational bioinformatics (Sarkar, 2011) – increased understanding of human genome may lead to more personalized medicine tailored from one’s genome (Hamburg, 2010)

21

Page 22: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Major applications in medical/clinical

informatics

• Based on two core types of information, with different uses and applications

– Person-specific information is generated in the care of patients

• Applications: electronic health records, telemedicine, etc.

– Knowledge-based information is the scientific literature of biomedicine and health

• Applications: information retrieval systems, evidence-based medicine

22

Page 23: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Person-specific informatics

applications

• Electronic health record (EHR)

– EHR definitions and components

– Secondary use (re-use) of clinical data

– HIE

– Overcoming barriers and spurring adoption

• Telemedicine

– Provision of care over time or distance via

communications technologies

23

Page 24: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Motivations – why do we need more IT

in healthcare?

• Quality

• Safety

• Cost

• Inaccessible information

24

Page 25: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Healthcare quality

• There are many studies to choose from…

• McGlynn, 2003– Sample of nearly 7,000 adults in 12 US metro areas assessed for

30 conditions

– On average, only 54.9% of care was consistent with known quality

• NCQA, 2009 – annual report on quality shows “gaps” to get all health plans to 90th percentile of current quality– 49,400-115,300 avoidable deaths

– $12 billion in avoidable medical costs

• Quality of care for patients with chronic disease no better and in many ways worse in US than for other developed countries (Schoen, 2009)

25

Page 26: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Safety and medical errors

• The IOM “Errors” report: As many as 98,000 Americans die each year due to medical errors, mostly medication errors (Kohn, 2000)– Some have argued that the numbers are too high or too low, but

none argue with the concept

– A decade later, problem persists (Van Den Bos, 2011)

• Lost in the discussion: Most errors are the result of faulty systems; the solution is not in making people smarter or punishing them, but building better “systems” to identify and prevent errors (Berwick, 2003)

• “Medicine used to be simple, ineffective, and relatively safe. Now it is complex, effective, and potentially dangerous.” (Chantler, 1999)

26

Page 27: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Cost

• Healthcare costs continue to rise and outpace inflation (Wilson, 2011)

• US spends more per capita on healthcare but gets less in terms of “products” (OECD, 2006; Angrisano, 2007) and “outcomes” (Banks, 2006; Lasser, 2006)

27

Page 28: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Inaccessible information

• Primary care physicians reported information missing in 13.6% of clinical visits (Smith, 2005)

– In 52% of instances, information was available but outside system

– In 44% of instances, lack of information could adversely effect patients

• As many as 20% of all tests and 1 in 7 hospital admissions may be result of inadequate access to information (David Brailer, unpublished data)

• HITECH investment provides opportunity to achieve the “learning health system” (Friedman, 2010)

28

Page 29: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

EHR definitions – key capabilities

(IOM, 2003)

• Health information and data

• Result management

• Order management

• Decision support

• Electronic communication and connectivity

• Patient support

• Administrative processes

• Reporting and population health management

and other documentation and

care

– Personal health records

– Clinical decision support

– Quality assessment

– Public health

– Clinical research

– Health information exchange

• Challenges

– Data quality

31

Page 32: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Clinical decision support (CDS)

• CDS uses EHR data to provide context-specific advice, alerts, and reminders, such as– Assisting with choices in diagnosis and therapy

– Detecting problematic situations, such as medication errors or drug-drug interactions

• Types of CDS– Information display – showing information in context of

situation

– Reminder systems – reminding clinicians to perform actions

– Alerts – alerting to critical clinical situations• Though growing concern over “alert fatigue”

– Clinical practice guidelines – guiding treatment to provide normalized care based on best evidence

32

Page 33: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

EHRs allow and align “secondary use”

(or “re-use”) of clinical data

• Additional uses of EHR data include (Safran, 2007)

– Personal health records (PHRs)

– Clinical and translational research – generating hypotheses and facilitating research

– Health information exchange (HIE)

– Public health surveillance for emerging threats

– Healthcare quality measurement and improvement

• One important tool for re-use of clinical data is natural language processing (NLP), which has been challenging but is seeing growing successes (Stanfill, 2010; Nadkarni, 2011; Chapman, 2011)

33

Page 34: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Example of an EHR

• Using the Veterans Health Information Systems and Technology Architecture (VistA)

• Why VistA?– A state-of-the-art EHR that has transformed

healthcare in the Veteran’s Health Administration (VHA) (Brown, 2003; Greenfield, 2004)

– Not that pretty, but has all of the modern features of the EHR, e.g., clinical decision support (CDS), computerized provider order entry (CPOE), etc.

– Distributed under open-source model, unlike most other vendors who do not even allow screen shots to be shown outside their customers’ institutions

34

Page 35: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Some details about VistA

• Is available as a demo– http://www.ehealth.va.gov/EHEALTH/CPRS_Demo.asp

– Demo version has following screens but not data

• Application has two components– Server written in M (formerly called MUMPS),

accessed via command-line interface• Runs in commercial Intersystems Cache (on many platforms)

or open-source GT.M (Linux only)

– Client written in Delphi and providers graphical user interface

• Only runs on Windows (just about all versions)

Some more about VistA

• The pure open-source version is also known as FOIA Vista

• There are two other streams of VistA activity– WorldVistA (www.worldvista.org) follows a more

traditional open-source pathway

– OpenVista(http://sourceforge.net/projects/openvista/) is more commercially oriented, and some vendors have proprietary extensions from the base code (Medsphere, 2010)

• There is a small but growing market for VistA, including in other countries (Conn, 2008)

56

Page 57: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

We also need to think beyond the EHR of a

single organization

• Patients are “mobile” – may develop medical problems or receive care away from their physician office or local hospital

– Of 3.7M patients in Massachusetts, 31% visited 2 or more hospitals over 5 years (57% of all visits) and 1% visited 5 or more hospitals (10% of all visits) (Bourgeois, 2010)

– Of 2.8M emergency department (ED) patients in Indiana found 40% of patients had data at multiple institutions, with all 81 EDs sharing patients in common (Finnell, 2011)

• Also greater need in public health sphere with growing threats of emerging diseases, bioterrorism, etc.

57

Page 58: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Beyond the EHR: health information

exchange (HIE; Kuperman, 2011)

• “Anytime, anywhere access to clinical information for the care of patients” – William Yasnoff, MD, PhD

• “Data following the patient” – Carolyn Clancy, MD, Director, AHRQ

• Requires that information seamlessly flow across business boundaries

– Challenges are not only technical, but also financial, legal, etc.

• But there are other successful examples of information exchange, such as ATM cards, wireless networks, etc.

58

Page 59: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Example of HIE: Indiana Health

Information Exchange• (McDonald, 2005)

• www.ihie.org

• Access to clinical information in real time by– Most hospital emergency departments

– Many hospital-based clinicians

– Some primary care providers in community

– Homeless care network

– Public school clinics

– County Health Department

– Indiana State Health Department

59

Page 60: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

“Results” of other HIE efforts have

been mixed

• Successful

– Inland Northwest Health System (INHS, www.inhs.org), Spokane, WA

– Massachusetts eHealth Collaborative (www.maehc.org) (Halamka, 2005; Gorroll, 2009)

• Less so

– Santa Barbara County Care Data Exchange –combination of technical, leadership, and funding problems (Miller, 2007; Brailer, 2007)

– Portland, Oregon (Conn, 2007)

60

Page 61: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Nationwide Health Information

Network (NwHIN)• http://healthit.hhs.gov/nhin

• HITECH investing $547M in state-level HIE as well as in standards and tools to facilitate NwHIN– e.g., Direct Project, wiki.directproject.org

61

Page 62: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

How much progress have we made?

• Systematic reviews (Chaudhry, 2006; Goldzweig, 2009; Buntin, 2011) have identified benefits in a variety of areas

• Although 18-25% of studies come from a small number of ‘health IT leader” institutions

62(Buntin, 2011)

Page 63: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Caveats about progress

• HIT may introduce error (Koppel, 2005) or

other unintended consequences (Ash, 2004)

• Report from National Research Council found

IT had not met its potential in healthcare

(Stead, 2009; good overview in: Conn, 2009

and Conn, 2009)

• Growing area of concern: HIT system safety

(Leviss, 2010; Sittig, 2011)

63

Page 64: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Why are we not there? What are the

barriers? (Hersh, 2004)

64

• Cost

• Technical challenges

• Interoperability

• Privacy and confidentiality

• Workforce

Page 65: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Cost barriers

• Even though there is overall return on investment (ROI), benefit does not accrue to those who pay, especially in small practices (Johnston, 2003)

– Practices only see 11% of ROI – most goes to insurance companies and laboratories

– But they are usually asked to pay the cost of EHRs

• Later data showed physicians achieved positive ROI around 2.5 years after initial investment, although range was wide (Miller, 2005)

65

Page 66: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Technical challenges

• While underlying technology (e.g., networks, relational database systems) is well-established, other technical issues remain, such as– Implementing systems, especially in office settings

(Carter, 2008; Daigrepont, 2011)

– Matching systems to workflow is essential – best systems add time in some areas but make it up in others (Overhage, 2001; Samuels, 2008)

• Most successful implementations have transformed care delivery and not just replaced paper records (Liang, 2010; Schulte, 2011)

66

Page 67: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Need for interoperability

• Clinical data is trapped in “silos,” not easily moved from one system to another (Brailer, 2005)

• Growing push for attention to “secondary use of clinical data,” which can align benefits for quality assessment, clinical research, public health surveillance, etc. (Safran, 2007)

• To achieve this, need standards for data elements, communications, etc. (EHRA, 2009; Benson, 2010)

67

Concerns about privacy and

confidentiality

• Much written, strong opinions (McGraw, 2009; ACP, 2009)

• VERY real, but– Security technologies are well-known and proven

effective

– Paper-based records are at least as insecure as EHRs and probably more so

– Human curiosity will trump even best methods, so we need to consider benefits vs. risks

– HIPAA is a mixed blessing; many argue for modification, e.g., (Ness, 2007; Nass, 2009)

HIT workforce – what do we know?

• Not much, other than it is important!

• Case study: implementation of computerized physician order entry (CPOE) showed adverse consequences– Mortality rate increased from 2.8% to 6.6% at Children’s

Hospital of Pittsburgh Pediatric ICU (Han, 2005)

– Increased mortality not seen at other academic centers (Del Baccaro, 2006; Jacobs, 2006)

– Pittsburgh adverse outcome may have been avoided with adherence to known “best practices” (Phibbs, 2005; Sittig, 2006)

• Problematic health IT implementations well-known, with failure often attributable to lack of understanding of clinical environment (Leviss, 2010)

69

Page 70: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Who is the HIT workforce? (Hersh,

2010)

• Three historical groups of HIT professionals

– Information technology (IT) – usually with

computer science or information systems

background

– Health information management (HIM) – historical

focus on medical records

– Clinical informatics (CI) – often from healthcare

backgrounds

70

Page 71: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

How many HIT personnel do we have

and do we need?• IT – to reach level of known benefit and meaningful use,

may need 40,000 (Hersh, 2008)

• HIM – from US Bureau of Labor Statistics occupational employment projections 2008-2018 (BLS, 2009)– Medical Records and Health Information Technicians (RHITs and

coders) – about 172,500 employed now, increasing to 207,600 by 2018 (20% growth)

• CI – estimates less clear for this emerging field– One physician and nurse in each US hospital (~10,000) (Safran,

2005)

– About 13,000 in healthcare (Friedman, 2008) and 1,000 in public health (Friedman, 2007)

– Growing role of CMIO and other CI leaders (Leviss, 2006; Shaffer, 2010)

US has low rates of adoption in

inpatient and outpatient settings• Adoption in the US is low for

both outpatient (Hsiao, 2010) and inpatient settings (Jha, 2010)

• By most measures, US is a laggard and could learn from other countries (Schoen, 2009)

• Most other developed countries have undertaken ambitious efforts, e.g.,– England (Hayes, 2008)

– Denmark (Protti, 2010)

Emerging national consensus is that

we need more – starts at the top

• Started with President George W. Bush

– State of the Union – mentioned every year 2004-2007

• January, 2004 – “Computerizing health records [can] reduce costs, improve care, and lower the risk of medical mistakes.”

• January, 2007 – “We need to reduce costs and medical errors with better information technology.”

– Goal of (EHRs) for all Americans by 2014

• http://www.whitehouse.gov/news/releases/2005/ 01/20050127-2.html

• Was elevated to even higher priority by President Barack Obama in HITECH Act (ARRA, 2009)

76

Page 77: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

We are now in a new “ARRA” of health

information technology (HIT)

• HITECH provides financial incentives for

“meaningful use” of HIT

– Incentives for EHR adoption by physicians and

hospitals (up to $29B)

– Direct grants administered by federal agencies

($2B)

• All initiatives overseen by Office of the National

Coordinator for Health IT (ONC,

http://healthit.hhs.gov/)

77

Page 78: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

What is “meaningful use” (MU) of an

EHR? (Stark, 2010; Blumenthal, 2010)• Driven by five underlying goals for healthcare system

– Improving quality, safety and efficiency

– Engaging patients in their care

– Increasing coordination of care

– Improving the health status of the population

– Ensuring privacy and security

• Consists of three requirements– Use of certified EHR technology in a meaningful manner

– Utilize certified EHR technology connected for health information exchange (HIE)

– Use of certified EHR technology to submit information on clinical quality measures

78

91

Page 92: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Telemedicine

• Delivery of healthcare where time and/or distance separate participants (Field, 2002)

• Classification of telemedicine (Hersh, 2001)– Store-and-forward– Office/hospital-based– Home-based

• Ongoing problem is quality of evaluation studies, which impedes coverage by insurers (Hersh, 2006; Ekeland, 2010)

• Most promising areas may be– Home telehealth (Darkins, 2008; Shea, 2009)– “Provider-to-provider” communications (Cusack, 2007;

McCambridge, 2010)

92

Page 93: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Applications of knowledge-based

information• Information retrieval (IR) systems, aka search

engines, are widely available– Virtually all of the world’s biomedical literature is now

available electronically, but significant challenges still exist to its use (Hersh, 2008)

• Evidence-based medicine (EBM) is a proper framework for finding and applying knowledge in clinical care (Straus, 2005; Guyatt, 2008; Guyatt, 2008)– Although it must be applied properly in the larger

context of healthcare (Haynes, 2002; Cohen, 2004)

93

Page 94: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Information retrieval – Hersh, 2009

• Focuses on indexing and retrieval of knowledge-based information

• Historically centered on text in documents, but increasingly associated with multimedia and even patient-specific information

• www.irbook.info

Page 98: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

The intellectual tasks of IR

• Indexing

– Assigning metadata to content items

– Can assign

• Subjects (terms) – words, phrases from controlled vocabulary, e.g.,

Medical Subject Headings (MeSH)

• Attributes – e.g., author, source, publication type

• Retrieval

– Most common approaches are

• Boolean – use of AND, OR, NOT

• Natural language – words common to query and content, usually

ranked by “relevance,” e.g., word counts, links (Google), etc.

98

Page 99: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Some IR systems have advanced features,

e.g., Pubmed limits, clinical queries, etc.

Some major IR challenges

• “Open access” publishing, especially to taxpayer-funded research (Björk, 2009)

– NIH Public Access Policy aims to disseminate taxpayer-funded research better (publicaccess.nih.gov)

– Includes deposit of papers or final submitted manuscripts into PubMed Central (pubmedcentral.gov)

– Publishers’ alternative approach is DC Principles for Free Access to Science (www.dcprinciples.org)

• Linkage across “silos” and other applications, e.g.,

– Digital Object Identifier (DOI) – www.doi.org

– CrossRef project – www.crossref.org

102

Page 103: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

IR challenges (cont.)

• What are best approaches for users to enter

queries and for systems to provide output, e.g.,

– Google works well for Web searches, but is it best for

biomedicine and health?

– What about the needs of biomedical researchers, who

collect increasing amounts of data and whose

research touches on many other areas?

– What are best approaches for consumers with

different levels of education, medical knowledge, etc.

(Fox, 2011)?

103

Page 104: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Applying EBM

• Steps of EBM

– Phrasing a clinical question that is pertinent and answerable

– Identifying evidence to address the question

– Critically appraising the evidence to determine if it applies to the patient

• There are some of the criticisms of the EBM approach (Cohen, 2004)

• This has led to growing advocacy for

– Evidence-based practice (Slawson, 2005; Dawes, 2005)

– Practical clinical trials (Tunis, 2003; Luce, 2009)

– Comparative effectiveness research (McGinnis, 2007; Murray, 2010)

Bioinformatics

• Area of informatics focused on cellular and molecular level– Usually associated with genomics, proteomics,

metabolomics, and other –omics

– Genome is the collection of all genes in an organism

• Translational bioinformatics focuses on application in human health and disease (Sarkar, 2011), presaging “personalized medicine” (Collins, 2010)

• New areas emerging due to changing nature of bioscience (Gibson, 2009; www.genome.gov)– Gene expression microarrays (Bier, 2008)

– Genome-wide association studies (GWAS) (Hardy, 2009)

107

Page 108: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Informatics challenges become more

complex as science advances

• It used to be so simple – the central dogma

– DNA → mRNA → protein

– Genes in exons; rest is “non-coding” (used to be called “junk,” but is found to be increasingly important)

– Growing understanding of role of microRNAs (Hanrahan, 2011)

• Increased recognition that genomic variation plays important roles in disease, consisting mainly of

– Single-nucleotide polymorphisms (SNPs) (Lupski, 2007)

– Copy-number variations (CNVs) (Redon, 2006; Chen, 2011)

108

Page 109: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Informatics challenges (cont.)

• Key focus now is genetic variation and its impact on health and disease (Hardy, 2009)

– Constant discovery of new genetic variants associated with development of common and uncommon diseases

– But need to be careful of spurious associations, e.g., the “incidentalome” (Kohane, 2006), and apply evidence-based approaches (Attia, 2009 – three papers)

• “High-throughput” technologies generate much data … and information needs, e.g., need for information retrieval and text mining (Cohen, 2005; Krallinger, 2008)

109

Page 110: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Increased understanding of molecular

basis of disease impacts bioinformatics• And vice versa

• Case in point: cancer– “Hallmarks” of cancer point to cellular activities that

reduce cell death while increasing invasiveness (Hanahan, 2011; Johnson, 2011)

– Growing evidence that these changes enabled by changes in genome and its function (Cowin, 2010)

– These changes are manifested temporally (Durinck, 2011) and more readily measured with newer sequencing technologies (Meyerson, 2010)

– New resources, such as the Cancer Genome Atlas (Chin, 2008) and PharmGKB (Thorn, 2010), will guide research, diagnosis, and treatment

110

Page 111: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Melding of bioinformatics and clinical

informatics: eMerge Network• Consortium aiming to link growing number of

biorepositories with sequenced DNA to data in EHR systems for “large-scale, high-throughput genetic research” (McCarty, 2011; Wilke, 2011)– Map the phenotype (EHR and tissue) to the genotype

(DNA sequences) using informatics

• Some early work includes use of NLP for– Replicating finding of known gene-disease associations

from research data in EHR data (Denny, 2010)

– Discovering new associations (Denny, 2010)

– Mapping to the phenotype, including controlled terminologies (Pathak, 2011)

111

Page 112: What is Biomedical and Health Informatics? · What is Biomedical and Health Informatics? William Hersh, MD Professor and Chair Department of Medical Informatics & Clinical Epidemiology

Informatics education and training

• Since a highly multi-disciplinary field, no standard curriculum or accreditation

– Listing of US programs on Web site of American Medical Informatics Association

• http://www.amia.org/education/programs-and-courses

– Description of OHSU program to follow as an example; consult other programs’ Web sites for details on their programs

– International perspective from International Medical Informatics Association (IMIA) recommendations (Mantas, 2010)

• Education has historically focused on academics but is evolving to meet the needs of practitioners and users

Educating the liaisons – 10x10

• Partnership with American Medical Informatics Association (AMIA) to meet Safran’s (2005) stated need to educate one physician and one nurse from each of the 6000 US hospitals in informatics– Original goal to educate 10,000 healthcare professionals by 2010

• Course consists of introductory on-line course and adding one-day face-to-face session– Initial offerings well-received (Hersh, 2007; Feldman, 2008)

– Over 1000 have completed by 2010• About 15% going on to further study

– Program has continued beyond 2010

– Other partners are also offering courses
