The emergency medicine department system: a study of the effects of computerization on the quality of medical records.
A template based computerized medical record system known as the Emergency Medicine Department System (EMDS) was installed in the emergency department of the National University Hospital, Singapore, replacing handwritten records. A study was carried out to show how the implementation of the EMDS improved the quality of medical records. A retrospective review of old manual records and the ones generated by the EMDS was done by means of a scoring system. The raw scores represent the amount of information captured. The calculated means of scores were then used to compare the records. It was found that EMDS improves the quantity of data capture over the old records in all sections compared. This was seen regardless of the experience of the user. The use of a non-structured generic template results in less data captured compared with a structured symptom-specific template. The design of questions has a great influence in that a double-choice question captures more data than single-choice questions. Building in 'locking' or enforcement mechanisms in the EMDS also helped achieve almost full capture of critical information, such as examination time.
