  24. 24. EHRs & HISEHRs & HIS The Challenge - Knowing What It Means Electronic Health Records (EHRs) Hospital Electronic Medical Records (EMRs) Hospital Information System (HIS) Records (EMRs) Electronic Patient C t B d Records (EPRs) Personal Health Clinical Information System (CIS)Computer-Based Patient Records (CPRs) Records (PHRs) System (CIS)
  25. 25. EHRsEHRs Commonly Accepted Definitions El t i d t ti f ti t b id• Electronic documentation of patient care by providers • Provider has direct control of information in EHRs • Synonymous with EMRs EPRs CPRs• Synonymous with EMRs, EPRs, CPRs • Sometimes defined as a patient’s longitudinal records over several “episodes of care” & “encounters” (visits)p ( )
  26. 26. EHR SystemsEHR Systems Are they just a system that allows electronic documentation of clinical care?clinical care? DiHi TDiag- nosis History & PE Treat- ments ... Or do they have other values?
  27. 27. Documented Benefits of Health ITDocumented Benefits of Health IT • Literature suggests improvement through – Guideline adherence (Shiffman et al, 1999;Chaudhry et al, 2006) – Better documentation (Shiffman et al, 1999) – Practitioner decision making or process of care (Balas et al, 1996;Kaushal et al, 2003;Garg et al, 2005) Medication safety– Medication safety (Kaushal et al, 2003;Chaudhry et al, 2006;van Rosse et al, 2009) – Patient surveillance & monitoring (Chaudhry et al, 2006)g ( y ) – Patient education/reminder (Balas et al, 1996) – Cost savings and better financial performanceg p (Parente & Dunbar, 2001;Chaudhry et al, 2006;Amarasingham et al, 2009; Borzekowski, 2009)
  28. 28. Functions that Should Be Part of EHR SystemsFunctions that Should Be Part of EHR Systems • Computerized Medication Order Entry (IOM, 2003; Blumenthal et al, 2006) • Computerized Laboratory Order Entry (IOM, 2003) • Computerized Laboratory Results (IOM, 2003) • Physician Notes (IOM, 2003) • Patient Demographics (Blumenthal et al, 2006) • Problem Lists (Blumenthal et al, 2006) • Medication Lists (Blumenthal et al, 2006)Medication Lists (Blumenthal et al, 2006) • Discharge Summaries (Blumenthal et al, 2006) • Diagnostic Test Results (Blumenthal et al 2006)• Diagnostic Test Results (Blumenthal et al, 2006) • Radiologic Reports (Blumenthal et al, 2006)
  29. 29. EHR Systems/HIS: Issues • Functionality & workflow considerations • Structure & format of data entryStructure & format of data entry – Free text vs structured data forms – Usability – Use of standards & vocabularies (e.g. ICD-10, SNOMED CT) – Templates (e.g. standard narratives, order sets) – Level of customization per hospital, specialty, location, group, clinician – Reduced clinical value due to over-documentation (e.g. medico-legal, HA) Special documents (e g operative notes anesthetic notes)– Special documents (e.g. operative notes, anesthetic notes) – Integration with paper systems (e.g. scanned MRs, legal documents) • Reliability & contingency/business continuity planningReliability & contingency/business continuity planning • Roll-out strategies & change management • InterfacesInterfaces
  30. 30. Computerized (Physician/Provider) Order Entry Functions Ph i i di tl t di ti /l b/di ti /i i• Physician directly enters medication/lab/diagnostic/imaging orders online • Nurse & pharmacy process orders accordinglyNurse & pharmacy process orders accordingly • Maybe considered part of an EHR/HIS system Values • No handwriting!!! • Structured data entry (completeness, clarity, fewer mistakes) • No transcription! • Entry point for CDSSs • Streamlines workflow, increases efficiency
  31. 31. Computerized (Physician/Provider) Order Entry Issues “Ph i i l k” f t ti• “Physician as a clerk” frustration • Usability -> Reduced physician productivity? • Unclear value proposition for physician?• Unclear value proposition for physician? • Complexity of medication data structure • Integration of medication lab diagnostic imaging &other ordersIntegration of medication, lab, diagnostic, imaging &other orders • Roll-out strategies & change management Washington Post (March 21, 2005) “One of the most important lessons learned to date is that the complexity f h h b il d i d”of human change management may be easily underestimated” Langberg ML (2003) in “Challenges to implementing CPOE: a case study of a work in progress at Cedars-Sinai”
  32. 32. Clinical Decision Support Systems (CDSSs) • The real place where most of the values of health IT can be achievedachieved • A variety of forms and nature of CDSSs – Expert systemsp y • Based on artificial intelligence, machine learning, rules, or statistics • Examples: differential diagnoses, treatment options Alerts & reminders– Alerts & reminders • Based on specified logical conditions • Examples: drug-allergy checks, drug-drug interaction checks, drug-lab interaction checks, drug-formulary checks, reminders for preventive services or certain actions (e.g. smoking cessation), clinical practice guideline integration – Evidence-based knowledge sources e.g. drug database, literature – Simple UI designed to help clinical decision making

  42. 42. Clinical Decision Support Systems (CDSSs) Issues F t ith i d li i l ti (K t t l 2005)• Features with improved clinical practice (Kawamoto et al., 2005) – Automatic provision of decision support as part of clinician workflow – Provision of recommendations rather than just assessmentsj – Provision of decision support at the time and location of decision making – Computer based decision support • Usability & impact on productivity
  43. 43. Clinical Decision Support Systems (CDSSs) Issues Al t iti it & l t f ti• Alert sensitivity & alert fatigue
  44. 44. Clinical Decision Support Systems (CDSSs) Issues Ethi l l l i• Ethical-legal issues – Liabilities: Clinicians as “learned intermediaries” – Prohibition of certain transactions vs. Professional autonomyy (see Strom et al., 2010) • Unintended Consequences (e.g. workarounds) See Koppel et al (2005) Campbell et al (2006) & Harrison et al (2007)– See Koppel et al. (2005), Campbell et al. (2006) & Harrison et al. (2007)
  45. 45. Clinical Decision Support Systems (CDSSs) Issues Ch i th i ht CDSS t t i• Choosing the right CDSS strategies • Expertise required for proper CDSS design & implementation • Integration into the point of care with minimal productivity/• Integration into the point of care with minimal productivity/ workflow impacts • Everybody agreeing on the “rules” to be enforcedy y g g • Maintenance of the knowledge base • Evaluation of effectiveness

  49. 49. Pharmacy Applications Issues Wh t di ti d i t l t i f t t hi h• Who enters medication orders into electronic format at which stage? • Unintended consequencesUnintended consequences • “Power shifts” • Handling exceptions (e.g. countersigns, verbal orders,g p ( g g , , emergencies, formulary replacements, drug shortages) • Choosing the right technology for the hospital • Goal: Workflow facilitation vs. medication safety?
  50. 50. Imaging Applications Picture Archiving and Communication System (PACS) C t hi d di l l t i i t d f• Captures, archives, and displays electronic images captured from imaging modalities (DICOM format) • Often refers to radiologic images but sometimes used in otherOften refers to radiologic images but sometimes used in other settings as well (e.g. cardiology, endoscopy, pathology, ophthalmology) • Values: reduces space, costs of films, loss of films, parallel viewing, remote access, image processing & manipulation, referralsreferrals Radiology Information System (RIS) or Workflow Management • Supports workflow of the radiology department, including patientSupports workflow of the radiology department, including patient registration, appointments & scheduling, consultations, imaging reports, etc.
  51. 51. Take-Away Messages • Health IT in hospitals comes in various forms L l t t i t t id ti• Local contexts are important considerations • Hospital IT is a very complex environment • Health IT has much potential to improve quality & efficiency of care• Health IT has much potential to improve quality & efficiency of care • But it is also risky... – Costs – Change resistance – Poor design Alert fatigue– Alert fatigue – Workarounds and unintended consequences – Use of wrong technology to fix the wrong process for the wrong goal • We need to have an informatician’s mind (not just a technologist’s mind) to help us navigate through the complexities
