Impact of electronic health records
Electronic health records (EHR) are “a longitudinal electronic record of patient health data produced by one or more encounters in any healthcare delivery setting. This data includes patient demographics, problems, medications, progress notes, vital signs, past medical history, immunizations, laboratory data, and radiology reports”.
The incorporation of EHR benefits both the patient and the organization, and it reduces overhead costs of maintaining paper records, facilitates routine maintenance of patient records and permits real-time access to records. It also stores vast data about patient demographics, disease characteristics and pharmacological and other investigations, which serve society in the form of literature for various types of research.
EHR capabilities include:
- Clinical decision support tools: This tool can assist the healthcare giver by providing up-to-date information about a drug and its interactions and alerts if abnormal test results are noted.
- Computerized physician order entry systems: This system enables automated records of all the laboratory, imaging and other pathological investigations ordered by a physician. This not only overcomes poor penmanship but also makes the ordering process organized.
- Health information exchange (HIE): This provides or exchanges patient information between providers. Thus, a patient saves time and money because repetition of the test is avoided.
