This study evaluated patient satisfaction levels in the emergency department of a hospital in New Delhi, India. Patients were assigned to either a test group that was informed about wait times and treatment procedures, or a control group that received no information. Questionnaires found that the test group reported significantly higher satisfaction levels than the control group for factors like wait times, staff behavior, and overall treatment. The study concludes that providing information to patients and managing expectations is more effective at improving satisfaction than just decreasing actual wait times.
