Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
