  • 55. Electronic Health Records/ Electronic Medical Records
  • 56. What Is A Medical Record?
  • 57. What Is A Medical Record? • A record or documentation of a patient’s medical history, examination, and treatments. • Medical Record vs. Health Record – Essentially the same
  • 58. Potential Uses of Medical Records • Continuity of providing care – Note important information for later use – Especially important in chronic diseases (e.g. hypertension, diabetes) or in follow-up (e.g. after surgery) • Patient safety – Preventing something bad because of lack of information – Such as drug allergies, list of current medications, “problem list”
  • 59. Potential Uses of Medical Records • Communications between providers – Referral to specialists or other physicians – Consulting among physicians – Communications between physicians and nurses, pharmacists, physical therapists, etc. – Transfer from a hospital to another • Medico-legal purposes – e.g. Court evidence against malpractice – What was done or provided to the patient? Why? By whom? When? – Was the care provided up to the professional standard?
  • 60. Potential Uses of Medical Records • Claims and reimbursements – What services were provided to the patient – How (and how much) will the hospitals/doctors be paid? – Audit of medical records by “payers” • Patient’s uses – Health insurance claims – Self-education & self-care • Clinical research – Find ways to improve health care through new knowledge
  • 61. Data Elements in Medical Records • Patient demographics • General information about each visit (visit = encounter) – Type (outpatient, inpatient, emergency) – Date/Time – Location (clinic or ward) “Clinical Notes” • Patient’s problems (“Patient history”) – Chief complaint – Present illness – Past history – Family and social history
  • 62. Data Elements in Medical Records • Clinical findings by physicians (“Physical examination”) – Any important positive (usually abnormal) findings – Also important negative (usually normal) findings • “Investigations” – Laboratory tests (blood tests, urine, etc.) – Radiological examinations (X-rays, CT, MRI, ultrasound) – Other diagnostic procedures • Electrocardiography (EKG/ECG) -- heart’s function • Electroencephalography (EEG) -- brain wave scans • Etc.
  • 63. Data Elements in Medical Records • “Problems” or “Diagnoses” – Summary of problems relevant to this visit • Treatments – Medications – Surgical procedures – Advice to patients – Admission (hospitalization) • Plans – Surgeries – More investigations to be done later – Follow-up appointments
  • 64. Data Elements in Medical Records • Inpatient clinical notes – Admission notes – Orders (medications, procedures, investigations, nursing care, etc.) – Medication administration records – Vital signs and other measurements – Results of lab tests and radiological examinations – Progress notes – Discharge summary
  • 65. “Electronic” Medical Records • Electronic Medical Records (EMRs) vs. Electronic Health Records (EHRs) • Debate about similarities & differences • Summary – Definitions subjective, depending on how people think – EMRs mostly refer to electronic documentation of medical care at one visit – EHRs mostly refer to electronic documentation that is longitudinal in nature (may be several visits) – EMRs commonly used in Thailand (but means the same as EHRs)
  • 66. Longitudinal Records • Records documented over time (multiple encounters) • Ideally, “life-long” is a complete record of the patient’s health
  • 67. Electronic Medical Records (EMRs) Computer-Based Patient Records (CPRs) Electronic Patient Records (EPRs)Electronic Health Records (EHRs) Personal Health Records (PHRs) The Confusing Acronyms Hospital Information Systems (HIS)
  • 68. • Are they just electronic documentation? • Or do they have some other values? Diag- nosis History & PE Treat- ments ... Electronic Health Record (EHR) Systems
  • 69. • Literature suggests improvement in health care through – Guideline adherence – Better documentation – Practitioner decision making or process of care – Medication safety – Patient surveillance & monitoring – Patient education/reminder – Cost savings and better financial performance Literature Shows Benefits of Health IT
  • 70. • Patient Demographics • Physician Notes • Computerized Medication Order Entry • Computerized Laboratory Order Entry • Computerized Laboratory Results • Problem Lists • Medication Lists • Discharge Summaries • Diagnostic Test Results • Radiologic Reports Functions That Should be Part of EHR Systems
  • 71. EHR Adoption: Thailand (2011) Estimate (Partial or Complete Adoption) Nationwide Basic EHR, combined inpatient & outpatient settings 49.8% Comprehensive EHR, combined 5.3% order entry of medications, combined 90.2% order entry of all orders, combined 79.4% Basic EHR: a score > 1 in a 5-point scale for IT support for demographics, MD notes, nursing assessments (inpatient only), discharge summaries (inpatient only), test results, order entry for medications Comprehensive EHR: a score > 3 in a 5-point scale for Basic EHR functions + electronic image viewing, order entry for lab tests and radiologic tests, drug-allergy alerts, drug-drug alerts

  • 77. • EHRs (or EMRs) are both – Electronic documentation of patient care and – 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) Summary
  • 78. • There are various kinds of applications in hospitals • HIS often refers to the “Front Office” part of hospital IT • Sometimes HIS refers to the entire hospital IT • HIS and EHRs are used to support clinical workflows, improve decision-making and care quality, and reduce costs • EHRs and HIS are just one piece of the big puzzle for the whole healthcare system Summary
