Emergency Department Data Collection EDIS (Emergency Department Information) System , Washington State

Hospital System

Background

The primary purpose of collecting Emergency Department data in EDIS is to:

• Assist clinicians in the management of patients; and

• Enable comparisons of performance in respect to access to services, quality clinical outcomes, patient management, customer satisfaction and cost effectiveness.

Each record in the collection represents a presentation to an emergency department.

Diagnosis coding

The EDIS Emergency Department Information System has diagnoses coded by trained clinical information managers who choose diagnoses from the Australian clinical version of the International Classification of Diseases (ICD-10). In addition, the EDIS has diagnoses recorded by medical, nursing or clerical personnel at the point of care. These personnel are not trained in clinical coding. The diagnoses are selected by keyword searching or tables of a limited set of diagnoses. The codes are assigned to the chosen diagnosis using tables built into the computer database program. Symptoms can be, and often are, selected as diagnoses. Diagnoses can be very specific or very broad. For example, someone with the same symptoms might be assigned a diagnosis of "influenza" or "viral infection". Emergency Departments have different visit types, the most common being an "Emergency Visit".
