For most people, waiting is inherently dissatisfying and emergency department patients are no exception. Most patients and people accompanying the patient find the treatment waiting time in emergency medical care facilities to be a source of great dissatisfaction. The dissatisfaction is compounded in many cases by the anxiety of all associated with the patient and the discomfort or pain the patient feels. Consequently it was not surprising to find in this investigation that waiting time for treatment and treatment cost were major causes of consumer dissatisfaction. Satisfaction of emergency department patients decreased as the medical need became less urgent. This finding should be of considerable concern to hospital administrators. With the trend toward new forms of health care delivery systems such as "emergicenters" and the increase in the number of physicians per capita, the emergency department will no longer be the most attractive or the only alternative available to the patients who have a nonemergency medical need. For emergency departments to remain profitable, it will be more important than ever before to meet the needs and expectations of their current and potential users. This can be accomplished by a program designed to reduce cost and waiting time and improve communication, and by other programs to educate the user so that the user's expectations more closely conform with what is actually needed or can be economically provided.
