Advantages and disadvantages of lockdown (self-isolation regime) introduced during the first wave of coronaviral infection for patients with polymorbid pathology

AIM: To study the structure of mortality not caused by coronavirus infection, in patients with polymorbid pathology during the period of self-isolation (lockdown). MATERIALS AND METHODS: Outpatient records of 2 423 patients with polymorbid pathology (841 males and 1 582 females, aged from 18 to 99 years) were examined. The mortality and its causes during three years including a period of lockdown were investigated. RESULTS: The overall mortality rate among patients with polymorbid pathology was 10.2% without differences in gender. The structure of the causes of death in patients with polymorbidity: cardiovascular diseases accounted for 50.8%, oncological diseases — 21%, nervous system diseases — 7.3%. During the lockdown, an increase in overall mortality by 34.3% was recorded (p < 0.05), with an increase in the number of deaths of patients with cardiovascular diseases by 19.5% (p > 0.05) (mostly patients with ischemic heart disease). CONCLUSION: An increase in the number of deceased patients with polymorbidity during the lockdown may be due to the limitation of physical activity, of the possibility of examination and consultation by profile specialists. Taking into account the vulnerability of this group of patients, there is an urgent need to develop preventive measures when the situation recurs.
