Abstract:
BACKGROUND: The pandemic of a new coronavirus infection, which began in the Chinese city of Wuhan in December 2019, has spread to more than 200 countries and territories. There are a number of studies, the results of which indicate that deaths are mainly registered among the middle-aged and elderly population with chronic non-communicable diseases. Most of these studies are based on the study of cases of COVID-19 with severe course or in hospitalized patients. At the same time, a greater number of patients, including those with chronic non-communicable diseases, carry COVID-19 to a mild degree and remain under the supervision of primary care physicians. AIM: To identify risk factors for the development of severe COVID-19 in patients with chronic non-communicable diseases who sought outpatient care during various periods of increased incidence of new coronavirus infection from March 2020 to February 2022. MATERIALS AND METHODS: The study was carried out on the basis of the Family Medicine Center of North-Western State Medical University named after I.I. Mechnikov, which provides primary health care to the population attached under compulsory health insurance. The design of the study was published earlier. A retrospective cohort study was conducted based on the analysis of outpatient records of patients who sought medical care at the Family Medicine Center during various periods of increased incidence of COVID-19: from 19.03.2020 to 30.06.2020 (group 1), from 1.10.2021 to 30.11.2021 (group 2) and from 18.01.2022 to 28.02.2022 (group 3). RESULTS: 343 patients were included in the study: 137 men (39.9%) and 206 women (60.1%). The number of patients with at least one chronic non-communicable disease was 232 (67.9%). It was found that the severity of COVID-19 is not affected by the presence of one or more chronic non-communicable diseases of mild severity in the patient. At the same time, grade II obesity and grade III hypertension are independent factors that significantly increase the risk of developing severe COVID-19 by 13.4 and 5.4 times, respectively (p 0.05). It should be noted that the combination of these diseases significantly increased the likelihood of developing severe COVID-19 by 11.9 times (p 0.05). CONCLUSIONS: Regardless of the period of morbidity, the clinical manifestations of COVID-19 in patients with chronic non-communicable diseases have their own characteristics: weakness, sweating, dry and wet cough are significantly more common (p 0.05). With each subsequent wave of increase in the incidence of COVID-19 in patients with chronic non-communicable diseases, there is a significant tendency to decrease the frequency of severe and very severe course of the disease, pneumonia and hospitalization, as in patients without chronic non-communicable diseases. It was found that the severity of the COVID-19 course is not affected by the presence of mild chronic non-communicable diseases in the patient. At the same time, grade II and higher obesity or grade III hypertension are independent factors that significantly increase the risk of developing severe COVID-19 by 11.9 and 5.4 times, respectively (p 0.05). The combination of these diseases significantly increased the probability of developing severe COVID-19 by 13.4 times (p 0.05).
