Research interests:
⢠Health IT applications in clinical settings (including
EHRs)
⢠Health IT âadoptionâ
⢠Health informatics education
5. What Is A Medical Record?
⢠A record or documentation of a patientâs
medical history, examination, and treatments.
⢠Medical Record vs. Health Record
â Essentially the same
7. Class Exercise 1
⢠Why do we need a health record?
⢠In other words, why do we need a
documentation of a patientâs medical care?
8. Potential Uses of Medical Records
⢠Continuity of providing care
â Note important information for later use
â Especially important in chronic diseases
(e.g. hypertension, diabetes) or in follow-up (e.g. after
surgery)
⢠Patient safety
â Preventing something bad because of lack of information
â Such as drug allergies, list of current medications,
âproblem listâ
9. Potential Uses of Medical Records
⢠Communications between providers
â Referral to specialists or other physicians
â Consulting among physicians
â Communications between physicians and nurses,
pharmacists, physical therapists, etc.
â Transfer from a hospital to another
⢠Medico-legal purposes
â e.g. Court evidence against malpractice
â What was done or provided to the patient? Why? By
whom? When?
â Was the care provided up to the professional standard?
10. Potential Uses of Medical Records
⢠Claims and reimbursements
â What services were provided to the patient
â How (and how much) will the hospitals/doctors be paid?
â Audit of medical records by âpayersâ
⢠Patientâs uses
â Health insurance claims
â Self-education & self-care
⢠Clinical research
â Find ways to improve health care through new knowledge
12. Data Elements in Medical Records
⢠Patient demographics
⢠General information about each visit (visit = encounter)
â Type (outpatient, inpatient, emergency)
â Date/Time
â Location (clinic or ward)
âClinical Notesâ
⢠Patientâs problems (âPatient historyâ)
â Chief complaint
â Present illness
â Past history
â Family and social history
13. Data Elements in Medical Records
⢠Clinical findings by physicians (âPhysical examinationâ)
â Any important positive (usually abnormal) findings
â Also important negative (usually normal) findings
⢠âInvestigationsâ
â Laboratory tests (blood tests, urine, etc.)
â Radiological examinations (X-rays, CT, MRI, ultrasound)
â Other diagnostic procedures
⢠Electrocardiography (EKG/ECG) -- heartâs function
⢠Electroencephalography (EEG) -- brain wave scans
⢠Etc.
14. Data Elements in Medical Records
⢠âProblemsâ or âDiagnosesâ
â Summary of problems relevant to this visit
⢠Treatments
â Medications
â Surgical procedures
â Advice to patients
â Admission (hospitalization)
⢠Plans
â Surgeries
â More investigations to be done later
â Follow-up appointments
15. Data Elements in Medical Records
⢠Inpatient clinical notes
â Admission notes
â Orders (medications, procedures, investigations, nursing
care, etc.)
â Medication administration records
â Vital signs and other measurements
â Results of lab tests and radiological examinations
â Progress notes
â Discharge summary
16. âElectronicâ Medical Records
⢠Electronic Medical Records (EMRs) vs.
Electronic Health Records (EHRs)
⢠Debate about similarities & differences
⢠Summary
â Definitions subjective, depending on how people think
â EMRs mostly refer to electronic documentation of
medical care at one visit
â EHRs mostly refer to electronic documentation that is
longitudinal in nature (may be several visits)
â EMRs commonly used in Thailand (but means the same
as EHRs)
17. Various Forms of Health IT
Hospital Information System (HIS) Computerized Provider Order Entry (CPOE)

22. Innovation Adoption
⢠Innovation: âan idea, practice, or object that
is perceived as new by an individual or other
unit of adoptionâ
â EHRs and health IT are innovation
⢠Adoption: âa decision to make full use of an
innovation as the best course of action
availableâ
⢠Diffusion of innovations theory (Rogers, 2003)
23. Class Exercise 3
⢠Why do we need to âadoptâ an
electronic version of medical
records?
24. Common âGoalsâ for
EHRs/Health IT Adoption
âComputerizeâ
âGo paperlessâ
âGet an electronic
copy
âDigital Hospitalâ
âHave EMRsâ
âModernizeâ
âShare dataâ
27. Landmark IOM Reports: Summary
⢠Humans are not perfect and are bound to make
errors
⢠Highlight problems in the U.S.
health care system that systematically contributes to
medical errors and poor quality
⢠Recommends reform that would change how health
care works and how technology innovations can help
improve quality/safety
28. Why We Need Health IT
⢠Health care is very complex (and inefficient)
⢠Health care is information-rich
⢠Quality of care depends on timely availability &
quality of information
⢠Clinical knowledge body is too large
⢠Short time during a visit
⢠Practice guidelines are put âon-the-shelfâ
⢠âTo err is humanâ
29. To Err Is Human
⢠Perception errors

â Free text vs structured data forms
â Usability
â Use of standards & vocabularies (e.g. ICD-10, SNOMED CT)
â Templates (e.g. standard narratives, order sets)
â Level of customization per hospital, specialty, location, group, clinician
â Reduced clinical value due to over-documentation (e.g. medico-legal, quality
accreditation)
â âCopy & Pasteâ garbage
â Special documents (e.g. operative notes, anesthetic notes)
â Integration with paper systems (e.g. scanned records, legal documents)
50. EHR Systems/HIS: Issues

(Why People Donât Use EHRs?)
⢠Technical & design issues
â Poor software implementation
⢠Does not meet requirements
⢠Buggy
â Poor usability and user experience
⢠Complex/clunky UI
⢠Easy to make error or miss something
â Poor system performance
⢠Slow
⢠Unreliable
57. EHR Adoption Barriers
(Why People Donât Use EHRs?)
⢠Management issues
â Does not seem to improve their work process
â Too much work entering data
â Unclear values to users (or even negative outcomes!)
⢠âUnintended consequencesâ of using health IT
â Executives not fully supporting the project
â âPower shiftâ among users
â Communications and engagement (involvement) of users
early and repeatedly during various phases of the project
â Poor training and technical support
â Users perceived they are treated poorly or their voices are
not heard
58. The Importance of âChange Managementâ
âOne of the most important lessons learned to
date is that the complexity of human change
management may be easily underestimatedâ
Langberg ML (2003) in âChallenges to implementing CPOE: a case study of a
work in progress at Cedars-Sinaiâ
60. Political Support Behind Health IT

(Blumenthal D, 2010)
68. Meaningful Use Final Rule:
Core Objectives (Selected)
⢠Electronic capture of information
â Demographics
â Vital signs
â Medication list
â Allergies
â Problem list
â Smoking
⢠Medication order entry
⢠Drug-allergy & drug-drug interaction checks
⢠Patient access to/copy of health information
69. Meaningful Use Final Rule:
Menu Set (Selected)
⢠Drug formulary checks
⢠Lab results incorporation into EHRs
⢠Generate lists of patients by specific conditions
⢠Medication reconciliation
⢠Electronic reporting to governmental agencies
⢠Advanced directives for elderly patients
⢠Patient reminders for certain services (for clinics)
⢠Patient access to health information (for clinics)
72. Personal Health Records (PHRs)
⢠âAn electronic application through which individuals can access, manage
and share their health information, and that of others for whom they are
authorized, in a private, secure, and confidential environment.â (Markle
Foundation, 2003)
⢠âA PHR includes health information managed by the individual... This
can be contrasted with the clinicianâs record of patient encounterârelated
information [a paperchart or EHR], which is managed by the clinician
and/or health care institution.â (Tang et al., 2006)
73. Types of PHRs
⢠Patient portal from a providerâs EHRs (âtetheredâ PHRs)
⢠Online PHRs
â Stand-alone
â Can be integrated with EHRs from multiple providers
(unidirectional/bidirectional data sharing)
⢠Stand-alone PHRs
â PC-based applications
â USB Drive
â CD-ROM or other data storage devices
â Paper
74. Ideal PHRs
⢠Integrated
⢠Accessible
⢠Secure
⢠Comprehensive
⢠Accurate & current
⢠Patient able to
manage sharing &
update information
⢠Engaging &
educational
⢠User-friendly,
culturally & literacy
appropriate
The âHub and Spokeâ Model
(Kaelber et al., 2008)
75. Use Cases of PHRs
⢠Data entry/update by patients
⢠Data retrieval by providers
â With patientâs consent
â âBreak-the-glassâ emergency access
⢠Data update from EHRs
⢠Privacy settings
⢠Personalized patient education
⢠Communications with providers
79. Implications
⢠This is why we need standards!!!
â Information exchange from one EHR system to
another needs standards
â Seamless exchange of information would
improve quality, continuity, and efficiency of
care
80. Summary
⢠EHRs (or EMRs) are both
â Electronic documentation of patient care and
â a broad term for an information system used to
improve the process of patient care through
better documentation and other care
processes such as ordering medications, lab
tests, or x-rays and viewing lab results and x-
ray reports (among others)
81. Summary
⢠It is important to focus both on the technical aspect of
EHR implementation as well as the management
aspect (such as change management)
⢠Otherwise, a well-designed system may not be used,
and patient care is not improved
⢠Many countries are trying to improve the EHR
âadoption rateâ
⢠EHRs are just one piece of the big puzzle for the
whole healthcare system
⢠PHRs are a separate, but related concept of EHRs
