While some EHRs were developed on minicomputers, most were initially developed on large mainframe computers and in either case had limited storage, which required the use of removable disk packs and/or tape for extra data storage, nightly downtimes for database back-up, and dedicated/wired terminals. Some EHRs developed between 19 were developed with hierarchical or relational databases, around or added to hospital billing and scheduling systems while others such as COSTAR, PROMIS, TMR, and HELP were developed as clinical systems to help improve medical care and for use in medical research. Initially, EHRs were developed and used at a number of academic inpatient and outpatient medical facilities, but none contained all the information in the paper chart and most EHRs today are still a hybrid collection of computerized and paper data ( Table 1). Finally, we will discuss the expected state of EHRs in the 25 years. This paper also discusses the expectations for EHRs in 1992 and which of these were realized, what events accelerated or disrupted/derailed EHR evolution. For the 25 th anniversary of the Yearbook of the International Medical Informatics Association (IMIA), this paper focuses on the overall state and use of EHRs in 1992 and how they have evolved by 2015. Information on specific studies is beyond the scope of this paper and not included.

Thousands of published studies report on EHRs increasing use, clinical decision support’s (CDS) ability to improve or not improve the healthcare process or clinical outcomes, evaluation methods, implementation/adoption, clinical trial patient identification, numerous new applications, and unintended consequences.
The use of EHRs has not only made patients’ medical information easier to read and available from almost any location in the world, but also changed the format of health records, and thus changed health care. New computer technology developed in the 1960s and 1970s laid the foundation for the development of the Electronic Heath Record (EHR). Traditionally, health records were written on paper, maintained in folders divided into sections based on the type of note, and only one copy was available. In recent years, the term health record has received prominence based on the fact that a patient’s medical information should include health and lifestyle information beyond just episodic medical encounters.
Medical record, medical chart, and health record are different terms used to describe the documentation of a patient’s medical history and care. However, paper medical records were not steadily used until 1900-1920. Translation of ancient Egyptian hieroglyphic inscriptions and papyri from 1,600-3,000 BC indicate the use of medical records.
