Objective: The present study aims to investigate a patient with a large number of admissions to adult emergency service, to understand the cost of the patient to the public through the number of admissions and the invoice amount, and to reveal the solutions available for such patients. Introduction: Emergency services are the units providing free health services with intensive patient admissions in Turkey. Emergency department admissions were gradually increasing in recent years, with claims that emergency services are being abused by patients. Results: Our patient was found to admit to the emergency department 266 times in two years for reasons such as substance abuse, excessive drug use, and self-harm, and he was hospitalized 4 times in the service and 9 times in the intensive care unit. The invoice total of the examination and treatment bill was 21,763.05 Turkish Lira. Conclusion: Patients with addictions and psychiatric disorders have the potential to harm themselves and cause multiple emergency service admissions, leading to increased workload in the emergency service. It may be necessary to address these patients differently than other patients and to conduct a more detailed examination.
