INTRODUCTION[|]During the pandemic, various measures have been taken from the Ministry of Health to family health centers to minimize the effects of COVID-19 on both society and the healthcare system. It is crucial to quickly revise the hospital for such a large pandemic crisis to effectively treat patients that require hospitalization or intensive care. It is vital to act quickly, postpone the treatment of elective patients, and make room for patients affected by the pandemic. It is also important that the same diagnostic and treatment algorithms are followed all over the country to get reliable feedback. In this study, we share our experience in the successful management of the COVID-19 outbreak between March 11 and May 7, 2020, and investigate the role of the hospital organization in the success of the treatment.[¤]METHODS[|]Kartal Dr. Lütfi Kırdar Training and Research Hospital has been declared as a pandemic hospital by the Ministry of Health on March 11, 2020. To hospitalize patients diagnosed with COVID-19, 500 pandemic patient beds were arranged in 31 clinics.[¤]RESULTS[|]Until this date, 37350 polyclinic examinations have been performed for COVID-19. The highest number of outpatient examinations was reached by 1656 on April 20, 2020. By the end of March, there was a noticeable increase in both the number of inpatient and outpatient clinics. Through pandemics, a total of 2536 patients was hospitalized, 163 of them were children. While 2087 (82%) of our inpatients were discharged, 255 (10%) of the patients are still being treated in our institution.[¤]DISCUSSION AND CONCLUSION[|]In conclusion, we think that in the diagnosis and treatment of COVID-19, having adequate physical space and sufficient workforce, and carrying out the treatment process with a good organizational chart will help us treat patients in a shorter time and will contribute to the reduction of morbidity and mortality.[¤]
