title: Emergency department resource use by patients with migraine and asthma in a health maintenance organization.
abstract: OBJECTIVE
  To identify and compare the resources consumed by patients with symptoms of asthma or migraine who presented to the Walk-In Emergency Department (WIED).
  
  
  METHODS
  Chart review.
  
  
  METHODS
  WIED, Group Health Cooperative of Puget Sound, Seattle, WA.
  
  
  METHODS
  Identified via WIED records as having visited the WIED between October 1991 and February 1992 for migraine or asthma.
  
  
  METHODS
  Time spent in the WIED, medications administered during visit and prescribed at discharge, diagnostic procedures performed, referrals, and hospitalizations.
  
  
  RESULTS
  Of 16,755 WIED visits during the study period, 323 (1.9%) were migraine related and 159 (1.0%) were asthma related. Ninety percent of the asthma patients and 62% of the migraine patients reported having self-medicated prior to going to the WIED; 89% of the migraine patients received additional medication at the WIED versus 57% of the patients with asthma. Fifty-four (35.5%) of the migraine patients and 7 (4.6%) of the asthma patients had more than 1 WIED visit during the study period.
  
  
  CONCLUSIONS
  Patients with asthma and migraine present striking contrasts in the types of resources used during WIED visits. This descriptive research highlights the need for further evaluation of the appropriateness of the healthcare services provided.
