4. 4 Level 2: Computerized Medical Record (document imaging) Level 5: Electronic Health Record (longitudinal, comprehensive) (longitudinal, comprehensive) Level 3: Electronic Medical Record (Active tool, organization level) Level 4: Electronic Patient Record (spans across organization) Level 1: Automated Medical Record ( clinical info systems)

5. 5 Level 1:Automated Medical Record the health care organization still depends on paper-based medical record system, although nearly half of the patient information may be computer generated and stored as computer printouts within the medical record.

6. The health care organization may automate certain functions such as patient registration, scheduling, results (radiology and laboratory) reporting, and dictation. However, at this level the paper- based medical record system remains the primary source for entering and retrieving the patient’s clinical information, and 6

7. the problems inherent in using paper records (availability, legibility, completeness) still exist. Automated medical records are managed by organizations. 7

8. 8 Level 2: Computerized Medical Record. The next level 2, involves digitizing the patient’s medical record through the use of a document imaging system. Much of the patient’s clinical information is scanned into the medical record and stored electronically as optical images.

9. Document imaging systems may be used by organizations to address accessibility and retrieval concerns and space and storage issues associated with paper medical records. However 9

10. In other words, the computerized medical record has essentially the same structure as the paper- based medical record. Like the automated medical record, the computerized medical record is maintained by the organization. 10

11. Many health care organizations opt not to use document imaging systems. They see them as a costly storage medium and as an unnecessary step in getting to the next level, the electronic medical record. 11

12. 12 Level 3: Electronic Medical Record. Up until this point the medical record has served as a passive storage device. It is at Level 3, the electronic medical record (EMR), where we begin to see the patient record as an active tool that can provide the clinician with decision- support capabilities and access to knowledge resources, reminders, and alerts.

13. Although still used and maintained at the organizational level, the EMR provides the clinician with access to decision- support capabilities and other aids. For example, the EMR may alter the clinician to the fact that the patient is allergic to certain medications or that two medications should not be taken in combination with each other. It may trigger a reminder that the patient is due for a health maintenance test such as a mammography or cholesterol test. 13

14. 14 Level 4: Electronic Patient Record Whereas the electronic medical record contains only the patient information that is maintained by a single organization. The electronic patient record includes all health care-related information concerning the patient---gathered across two or more organizations.

15. An electronic patient record brings together in a central database all clinical information available on a patient. For example if a primary care physician saw a patient in the physician’s office, admitted the patient to a hospital, and then discharged the patient to a rehabilitation facility, all relevant information concerning the patient would be available to clinicians involved in the patient’s care across these three settings. 15

16. This level of computerization requires (1) a system of identifying all patient information available, (2) a way to combine information from multiple facilities, (3) a common terminology and structure, and (4) a consensus on security. The electronic patient record system is comparable in its scope and functions to the CPR. 16

17. 17 Level 5: Electronic Health Record The electronic health (EHR) is broader in scope than the electronic patient record and includes wellness information and other information not routinely maintained by health care organizations.

18. Wellness information might include data on the individual’s smoking habits, nutrition, level of exercise, dental health and alcohol use. The patient is at the center and all information related to the individual’s health and wellness is brought together as needed in managing the patient’s care and treatment more effectively. 18

19. The EHR is a longitudinal record and ultimately would encompass as person’s relevant health information from before birth to death. # 19
