Outline

• Healthcare & Information • Why We Need ICT in Healthcare • Health IT • Hospital Information Systems • Health Information Exchange • Q&A

2 What Clinicians Want?

To treat & to care for their patients to their best abilities, given limited time & resources

• Safe • Timely • Effective • Patient-Centered • Efficient • Equitable

Institute of Medicine, Committee on Quality of Health Care in America. Crossing the quality chasm: a new health system for the 21st century. Washington, DC: National Academy Press; 2001. 337 p. 4 Information is Everywhere in Healthcare

Shortliffe EH. Biomedical informatics in the education of physicians. JAMA. 2010 Sep 15;304(11):1227-8. 5 Why We Need ICT in Healthcare?

#1: Because information is everywhere in healthcare

6 Landmark IOM Reports

(IOM, 2000) (IOM, 2001) (IOM, 2003) (IOM, 2011)

7 Patient Safety

• To Err is Human (IOM, 2000) reported that: – 44,000 to 98,000 people die in U.S. hospitals each year as a result of preventable medical mistakes – Mistakes cost U.S. hospitals $17 billion to $29 billion yearly – Individual errors are not the main problem – Faulty systems, processes, and other conditions lead to preventable errors

Health IT Workforce Curriculum Version 3.0/Spring 2012 Introduction to Healthcare and Public Health in the US: Regulating Healthcare - Lecture d 8 IOM Reports Summary

• Humans are not perfect and are bound to make errors • Highlight problems in U.S. health care system that systematically contributes to medical errors and poor quality • Recommends reform • Health IT plays a role in improving patient safety

9 To Err is Human 1: Attention

• Economist.com subscription $59 68 Ariely (2008) • Print & web subscription $125 32

12 Cognitive Biases in Healthcare

“Everyone makes mistakes. But our reliance on cognitive processes prone to bias makes treatment errors more likely than we think”

Klein JG. Five pitfalls in decisions about diagnosis and prescribing. BMJ. 2005 Apr 2;330(7494):781-3. 13 Common Errors

• Medication Errors – Drug Allergies – Drug Interactions • Ineffective or inappropriate treatment • Redundant orders • Failure to follow clinical practice guidelines

14 Why We Need ICT in Healthcare?

#2: Because healthcare is error-prone and technology can help

15 Why We Need ICT in Healthcare?

#3: Because access to high-quality patient information improves care

16 Health IT

Use of information and communications technology (ICT) in health & healthcare settings

Slide adapted from: Boonchai Kijsanayotin 17 Health IT: What’s in a Word?

Health Goal Information Value-Add Technology Tools

18 “Health” in “Health IT”

• Patient’s Health • Population’s Health • Organization’s Health (Quality, Reputation & Finance)

19 Various Forms of Health IT

Hospital Information System (HIS) Computerized Provider Order Entry (CPOE)

Electronic Health Records Picture Archiving and (EHRs) Communication System (PACS) Screenshot Images from Faculty of Medicine Ramathibodi Hospital, Mahidol University 20 Still Many Other Forms of Health IT

Biosurveillance

mHealth

Personal Health Records Telemedicine & (PHRs) and Patient Portals Telehealth

Images from Apple Inc., Geekzone.co.nz, Google, HealthVault.com and American Telecare, Inc. 21 Values of Health IT

• Guideline adherence • Better documentation • Practitioner decision making or process of care • Medication safety • Patient surveillance & monitoring • Patient education/reminder

22 Enterprise-wide Hospital IT

• Master Patient Index (MPI) • Admit-Discharge-Transfer (ADT) • Electronic Health Records (EHRs) • Computerized Physician Order Entry (CPOE) • Clinical Decision Support Systems (CDS) • Picture Archiving and Communication System (PACS) • Nursing applications • Enterprise Resource Planning (ERP) - Finance, Materials Management, Human Resources

23 Departmental IT in Hospitals

• Pharmacy applications • Laboratory Information System (LIS) • Radiology Information System (RIS) • Specialized applications (ER, OR, LR, Anesthesia, Critical Care, Dietary Services, Blood Bank) • Incident management & reporting system

24 HIS - EHR – EMR – PHR relationship

Hospital InformationEHR Systems EMR PHR EHR= Electronic Health Record EMR= Electronic Medical Record PHR= Personal Health Record Computerized Provider Order Entry (CPOE)

26 Computerized Provider Order Entry (CPOE)

Values • No handwriting!!! • Structured data entry: Completeness, clarity, fewer mistakes (?) • No transcription errors! • Streamlines workflow, increases efficiency

27 Stages of Medication Process

Ordering Transcription Dispensing Administration

Automatic Electronic CPOE Medication Medication Dispensing Administration Records (e-MAR) Barcoded Medication Barcoded Dispensing Medication Administration 28 Clinical Decision Support Systems (CDS)

• The real place where most of the values of health IT can be achieved

– Expert systems • Based on artificial intelligence, machine learning, rules, or statistics • Examples: differential

(Shortliffe, 1976) diagnoses, treatment options

29 Clinical Decision Support Systems (CDS)

– Alerts & reminders • Based on specified logical conditions • Examples: – Drug-allergy checks – Drug-drug interaction checks – Reminders for preventive services – Clinical practice guideline integration

30 Example of “Reminders”

31 More CDS Examples

• Reference information or evidence- based knowledge sources – Drug reference databases – Textbooks & journals – Online literature (e.g. PubMed) – Tools that help users easily access references (e.g. Infobuttons) 32 Infobuttons

Image Source: https://webcis.nyp.org/webcisdocs/what-are-infobuttons.html 33 Other CDS Examples

• Pre-defined documents – Order sets, personalized “favorites” – Templates for clinical notes – Checklists – Forms • Can be either computer-based or paper-based

34 Order Sets

• Simple UI designed to help clinical decision making – Abnormal lab highlights – Graphs/visualizations for lab results – Filters & sorting functions
