Electronic patient record in primary care TDT4210 Health care informatics Professor Anders Grimsmo, DMF, NTNU 1935
- a challenge to NTNU: Create a productive and viable competence community for research, development, implementation and knowledge sharing in conjunction with electronic patient record (EPR). • Five millions NOK for five years

Information exchange in primary care Is written and sent: • 20 millons single bills to national assurance (contact bills). • 1,9 millons referrals to hospital or specialist • 3,8 millons epicrises from hospitals and out-patients’ clinics • 1,0 millons physiotherapist requisitions • 1,3 millons image requisitions • 3,5 millons medical certificates and sickness benefit certificates • 200.000 medical certificates on disablement • 7 millons test requisitions to laboratories, each with 6-7 analyses • 17 millons prescriptions per year

Diagnosis - name of disease based on: • Information from the patient • The anamnesis • Symptoms • Clinical investigations • Laboratory tests To diagnose is to classify
Migraine Criteria: Recurrent episodes of headache with three or more of the following finds: unilateral headache, nausea/vomiting, aura, other nevrological symptoms, migrain in the family Inclusion: vascular headache with/without aura Expulsion: cervikogen headache, cluster-headache, tension headache
Diagnostic process Name disease/-problem Arrange classes Collect information Classify Reason for contact/ hospitalization Symptoms, clinical finds, lab. results Inclusion and expultion criteria Diagnosis criteria Code Classification of diagnosis Classification of Diagnoses
Systems for diagnosis class. Hospitals and specialist services: ICD(International Classification of Diseases) Primary care services: ICPC(International Classification of Primary Health Care)
Main objective of the patient record - is now documentation: • Medical, for the physician as a tool in diagnostics and treatment • Juridical, for the patient according to rights. • in the future also: • Communication • Decision support
Main functions in todays EPR: • Pasient data/card file function • Contacts and diagnosis • Record notes (free text about symptoms, finds and considerations) • Prescription module • Laboratory module – requisitions and answers • Correspondance – Referrals, certificates, word processing • Schemes – archive, filling in • Appointment book/waiting list • Accounting module • Simple statistics
ERP challenges A record which can give: • Better overview and be adapted to the working methods of the general practitioner • Support in diagnose and treatment • Quality assurance of procedures • Information sharing • Information reuse
Mirror the contents and process of the consultation S Subjective – symptoms (anamnesis) Objektive – Signs and finds (clinical examination/tests) Assessment – Considerations and conclusion (diagnosis) Plan – effectuation of action (prescr, report sick etc.) O A P
Problem oriented record "While the core of earlier patient records were schemes of book-keeping, the core of EPR ought to be the patient’s health problems represented by episodes of care"

Information needs in daily work • Questions arise regularly while working with patients: • attached to treatment, most often medication • can be about much more than medical knowledge • passes usually unanswered • Preferably physicians ask their colleagues – oral/on the phone relevance x validity • Information utility value = the effort needed to find the info
Guaranteed to create problems ? Error • Use models and routines from ”best-practice” as foundation • Convey models and systems from private sector and into the public health care sector • Try to convey solutions developed in one county, to another
