During COVID-19 pandemic Follow-up Centers were established by Turkish Ministry of Health (MoH) to detect possible complications in recovered COVID-19 patients at an early stage and make necessary interventions on time. It was aimed to reveal the short, medium and long-term effects of the disease by monitoring regularly. The Follow-up Center algorithms were designed by 10 clinicians of different branches with the support from United Nations Development Programme (UNDP). The follow-ups were made for one year in two pilot centers by using the health information systems infrastructure. In the dissemination process, Follow-Up centers were established initially in 24 and subsequently in 81 provinces.

In this study, the establishment, dissemination, operation and patient follow-up process of the COVID-19 Follow-up Centers were examined. The one-year (between 1 December 2021 and 1 December 2022) data obtained were analyzed. The patient follow-up;

• • was made at 0, 1, 3, 6 and 12 months for the first year,

• • planned to be made twice in the second year and the following years if needed.

In the first year, people who received 3 follow-ups by using the forms and scales in the integrated information system modules were assumed to be followed up regularly.

Among the one-year data obtained from the COVID-19 follow-up centers, the total number of follow-ups, the distribution of follow-ups by date, gender and age groups and symptoms according to time were examined. In the first year; 11,288 people were included in the follow-ups and 18,328 follow-ups were made; 2,462 people were followed-up regularly. The followed up people consisted of 51.8% women; 48.3% of them were men. The incidence of symptoms decreased from 1,198 people in the first follow-up and to 180 people in the third follow-up.

The establishment of Follow-up Centers is considered to be an important initiative to generate systematic data on the long-term effects of COVID-19. It was concluded that conducting studies using two-year data obtained from the follow-up centers, especially for complications, would be beneficial for management of the COVID-19 pandemic and in preparation for similar pandemics.
