Survey On Electronic Medical Record Search Engine In Healthcare

Abstract

Data at a high rate are produced at a higher rate by healthcare organisations. This leads to many benefits, but at the same time, it has drawbacks too. There is a rapid growth of free-text clinical documents in health care sectors that are generating alarge amount of EHRs data. Every patient has his medical chart. A patient's basic clinical data and medical details, which includes crucial signs, medications, demographics, examinations, plans of treatment, improvement notes, threats, dates of immunisation, allergies, radiology images and laboratory and test results, are maintained as a complete record named as a medical chart. Data from various sources, including medical Information, patient surveys, and administrative databases used to pay bills or manage care, are collected. An accumulation of patients' records saved in a computer is a medical database.

Health care providers termed it a computer-stored patient record, an electronic patient record, an electronic health record, or an electronic medical record. Accessing Information from the medical and healthcare domain is a challenging task while considering the time is taken and the accuracy of the retrieved information. Health records are private, so we can only access some patients records if we are authorised. So we have collected plenty of journals related to retrieving Information from an electronic health record. So we have discussed different information retrieval techniques, methods, and search engines for accessing health data from the medical database. Several limitations and future issues are explained.
