Zaïane, Ph.D. Professor Department of Computing Science 352 Athabasca Hall Edmonton, Alberta Canada T6G 2E8 Telephone: Office +1 (780) 492 2860 Fax +1 (780) 492 1071 E-mail: zaiane@cs.ualberta.ca http://www.cs.ualberta.ca/~zaiane/ Computer Scientist No medical training Specialize in Data Mining Many years of sporadic experience designing and implementing health care systems Not a chronic patient yet

3. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management What kind of information is collected in health care? Who collects it? Why is it collected? What is it used for? By who? Where is stored Who does it belong to? Who is entitled to access it?

4. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Example: Physicians assess patient status; Clinicians administer treatment; Administrators determine appropriate staffing levels; Administrators manage inventory of supplies; Administrators negotiate contracts and payment for services; Pharmacists manage inventory of drugs; Administrators and statisticians evaluate clinical outcome, quality and cost of healthcare provided per population; Politicians make decisions investing in new services or eliminating underutilized services; Researchers analyze and compare clinical treatment and outcome and devise new treatments

6. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Patient Profile: Mary Smith Mrs. Mary Smith –73 year old female –recently moved to Red Deer –previously lived in Toronto Where are her medical records? –Not in Red Deer –Not in Alberta –Spread in Ontario (Toronto hospitals, health centres, etc.) What will happen if she needs them?

7. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Mrs. Smith visits the Red Deer regional hospital She has come for an “Initial Visit” appointment at 10:00am with Dr. Robertson Upon arrival, Mrs. Smith checks in with the front desk Front desk staff enters her information into the registration system

8. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Ideal Scenario on Information Flow Red Deer Registration System Health System 1 Health System 2 Health System 3 Health System n Local HIS Interface 1- New Patient message Interface Engine / Aggregator GatewayFederal Aggregator 2- Internal Request 3- External Request 4- External sites identified 5- Request information for Mrs. Smith 6- Receive data: Smith’s Medications and Allergies 7- Provide data

9. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management The data exchange occurs automatically and transparently, between registration at Red Deer and the health organization custodian of medical data in Ontario When Dr. Robertson walks into the exam room, Mrs. Smith’s known Medications and Allergies are available for review on local health information system Wish list

11. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Reality Check Mrs. Smith has 3 months to get an Alberta health card and number Dr. Robertson would ask Mrs. Smith about her medical history and her previous medical providers (doctors, hospitals, etc.) Dr. Robertson (or hospital) has to contact Mrs. Smith’s previous medical providers for her file. They might reply, by mail or fax. E-mail is not considered secure (but fax is ???) Her medical record in Alberta has to be created from scratch.

12. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Healthcare=Information Intensive Healthcare professionals = heterogeneous group with divers objectives and information requirements “The purpose of a HealthCare Information System is to manage the information that health professionals need to perform their jobs effectively and efficiently.”

13. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Automation of Healthcare Systems Historically, different units and services within a hospital were automated (introduction of IT) separately; Separate in terms of function, hardware, operating system, programming language, vendors; Connecting and communicating between the pieces is a challenging obstacle: consistency, updates, etc. Locating where the patient is and any given time; Identifying the kind of care provided; recognizing the clinical results, etc. are significant real challenges.

14. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Automation of Healthcare Systems Hospital Registration BillingMedical Unit Lab Unit Separate automation of specific functions within the hospital Integration via Interface Engine or Protocol (HL7)

15. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Separate functional automation Significant duplication; for instance registration and demographic data can be entered many times for the same visit. Contradictions and missing data Integration difficult and prone to error Software maintenance and upgrades expensive Infrastructure and training expensive

16. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Enterprise Automation Hospital Registration Billing Medical Unit Lab Unit automation within the hospital as a whole enterprise

17. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Automation of Healthcare Systems Healthcare Organization Integration via Aggregator/Mediator/Protocol (HL7) Healthcare Organization “The expertise gained from managing an inpatient driven organization (e.g. a hospital) does not translate easily to the successful management of other organizational activities, nor in some cases, even to other hospitals.” Idem for automation

21. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Personal Information Protection Alberta: Personal Information Protection Act (PIPA), 2003 ( http://pipa.alberta.ca/ ) –The purpose of this Act is to govern the collection, use and disclosure of personal information by organizations in a manner that recognizes both the right of an individual to have his or her personal information protected and the need of organizations to collect, use or disclose personal information for purposes that are reasonable. Ontario: Personal Health Information Protection Act (PHIPA); outlines privacy regulations for health information custodians Saskatchewan: Health Information Protection Act (HIPA), 2005 Canada: Personal Information Protection and Electronic Documents Act (PIPEDA), 2001 (applies to federally regulated industries) USA: Health Insurance Portability and Accountability Act (HIPAA), 1996 http://www.hipaa.org/ Not Health Specific

22. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Privacy of health information Why protect the privacy of health information? Do you know who accessed your health information this week? Do you know what they did with your health information? Does this concern you? What increased threats to privacy, if any, does the emerging ‘electronic health record’ pose? Privacy incorporates much more than “confidentiality” and “security”. Privacy is about protecting an individual’s right to have a choice about how their health information is handled. Challenge: maximise both the protection of individual privacy AND positive health outcomes. Identity theft and being impersonated may lead to financial losses Identity theft in healthcare and being impersonated may lead to death.

24. Health Informatics Survey INTD 560 O.R. Zaïane © 2009Health Information Management Patients can be active Participants The patient is a participant in their care with self-entered data and consent preferences for this data. Patient in control over what goes into the Personal Health Record and who has access to it. Some companies see this as business opportunity Let consumers opt-in to share the output from a device measuring their blood sugar or blood pressure or other medical sensors. This information is viewable in an aggregated format allowing for a more accurate overall clinical picture Clinicians can view self entered data as well as historical prescriptions and conditions from multiple sources electronically goals: “To create integrated online environments where you can create and store your personal records, get information, find doctors, make medical appointments, communicate online, manage medications, share information with providers and more.”
