The aim of this study was to study the effect of gender, age and social status on the severity of comorbidity and survival of outpatients. A retrospective analysis of 133 outpatient records of patients of one of the outpatient clinics in Minsk was carried out by the method of continuous random sampling, incl. 50 men (38%) and 83 women (62%). Comorbidity was studied using the following methods: CIRS system; Kaplan – Feinstein index, Charlson index. The study revealed comorbidity in 78.6% of outpatients with chronic diseases, and on average it corresponded to a mild degree (according to three methods). Among comorbid diseases, the most common combination of ischemic heart disease and arterial hypertension with osteoarthritis, discirculatory encephalopathy, and pathology of the gastrointestinal tract. Comorbidity was more common in female patients, elderly and senile patients, workers, pensioners and disabled people. A poor prognosis was established in 42.8% of comorbid patients (according to the Charlson index), with a ten-year survival rate of less than 21% in 35.1% of patients. Among those with a survival rate of less than 21%, elderly patients and people with disabilities predominate, while young people and employees have a survival rate of more than 99%.
