A computerized audit of 15,009 emergency department records.

The text of 15,009 emergency department medical records was reviewed with the use of a computer program that detected the presence or absence of key words and phrases. The search focused on "trigger diagnoses," that is, any diagnoses associated with an above-average risk for an undetected but more serious condition. Included were the trigger diagnoses from the five high-risk areas of extremity laceration, epiglottitis, abdominal pain, meningitis, and myocardial infarction. The three kinds of medical records that were compared were handwritten records, records dictated and transcribed, and records created by a voice-activated word processor. From a risk management perspective, inclusion of critical pertinent positives and negatives was taken as an index of quality from a risk management perspective, and records created by a voice-activated word processor using real-time risk management prompts were superior to handwritten and dictated records. The computer holds promise as a vehicle to reduce the cost and frequency of malpractice risk in the ED and as a teaching tool to improve the quality of care.
