The aim of the study is to investigate the frequency of thromboembolic complications and the factors influencing them in COVID-19 cases that did not require hospitalization. For this purpose, patients registered at two different family health centers in Istanbul were retrospectively screened, and their status regarding post-COVID-19 thromboembolic events was recorded. The sociodemographic characteristics, medical history, COVID-19 treatments received, comorbidities, and current medications of all patients were examined and compared with the occurrence of complications.
Studies on COVID-19 complications in the literature have predominantly focused on patients treated in hospitals, particularly in intensive care units. Data on patients with mild to moderate symptoms who were followed up on an outpatient basis in primary care are quite limited. Therefore, our research investigated the incidence of thrombotic events within six months following infection in mild to moderate COVID-19 cases and the factors that might influence these events. Records of 961 individuals registered at two different family health centers in Istanbul were reviewed. Patients were contacted by phone, informed about the study, and data regarding their sociodemographic characteristics, medical histories, COVID-19 infection experiences, and medications used were collected. Comparative analyses (Fisher's exact test) and logistic regression tests were conducted.
7,640 studies on the registry are indexed under COVID-19; 488 are open to participants now.
This study's enrollment of 961 is above the median of 261 across 3,136 observational studies indexed under COVID-19.

Patients over the age of 18 who were registered at family health centers in two different districts of Istanbul and had a confirmed COVID-19 infection verified by PCR test between January 1, 2022, and June 30, 2022, were included in the study.
Exclusion Criteria:
The frequency of thromboembolic complications in COVID-19 patients not requiring hospitalization.
Patients registered at a family health center were retrospectively reviewed, and those with a history of COVID-19 PCR positivity who had been followed up as outpatients were included. The occurrence of venous or arterial thromboembolism within the first 6 months after infection was recorded from their medical reports, and the frequency was calculated.
Time frame: january-june 2022
The relationship between patients' comorbidities and the occurrence of thromboembolic events post-COVID.
The patients' existing chronic conditions from the time of their COVID-19 infection were recorded by reviewing the family medicine system. The presence of chronic diseases was then analyzed in comparison to the occurrence of thrombosis within the first 6 months following COVID-19 infection.
Time frame: january-june 2022
The relationship between patients' medications and the occurrence of thromboembolic events post-COVID.
The medications regularly used by patients for their chronic conditions since the time of their COVID-19 infection were noted by reviewing records in the family medicine system. These medications were then analyzed in comparison to the occurrence of thrombosis within the first 6 months following COVID-19 infection.
Time frame: january-june 2022
