[New clinical guidelines for COPD - a paradigm shift: A review]

Chronic obstructive pulmonary disease is now one of the most common noncommunicable diseases and the main causes of morbidity, disability and mortality in the world. In recent years, new approaches to epidemiology, diagnosis, classification (categorization), evaluation of phenotypes, as well as characterization and assessment of the severity of сhronic obstructive pulmonary disease exacerbations have emerged. Modern approaches to starting and subsequent drug therapy have changed significantly. This is largely due to the results of recently conducted major clinical trials, demonstrated high efficacy of triple fixed combinations, including inhaled glucocorticosteroids, long-acting beta-agonists and long-acting anticholinergic drugs. The use of non-medication methods (smoking cessation, physical activity and respiratory rehabilitation) and modern approaches to the treatment of respiratory failure and antibiotic therapy remain important. In terms of their significance, all these updates have a significant impact on real clinical practice and can be considered as a novel paradigm of the approaches to the diagnosis and management of this disease.

[Causes of death in the Moscow region according to medical death certificates]

OBJECTIVE

Determination of the leading causes of death based on data from primary medical death certificates (MDCs) depending on the place of death.

MATERIAL AND METHODS

From the electronic database of the Main Department of the Civil Registry Office of the Moscow Region (the USR registry office system) for 2021, all cases were selected in which diseases were indicated as the primary cause of death (PCD); all codes of external causes, injuries and poisonings were excluded. A total of 109.126 cases, 50.6% died in the hospital, 34% died at home, and 16.4% died elsewhere. Bureau of Forensic Medical Examination (BFME) issued 45.2% of MSS. Taking into account the frequency of use of ICD codes, the clinical similarity of individual codes, 20 groups were formed, which accounted for 90.1% of deaths from diseases.

RESULTS

The frequency of registration of individual groups of causes of death largely depends on the place of death. 5 leading groups of causes of death were established: 1) in general from COVID-19 23.55%, chronic ischemic heart disease (CIHD-1) without postinfarction cardiosclerosis, aneurysm and ischemic cardiomyopathy (CMP) 14.5%, from encephalopathy indefinite (EI) 11.4%, malignant neoplasms (MN) 11.3%, stroke 6.2%; 2) in a hospital from COVID-19 45%, stroke 10%, MN 8.3%; CIHD-1 7.1%, CIHD with a history of MI/ischemic CMP 2.7%; 3) at home from CIHD-1 21.8%, EI 21.5%, MN 15.5%, from diseases associated with alcohol 3.3% and brain cyst 3.3%; 4) elsewhere from CIHD-1 22.7%, EI 21.6%, MN 12%, from other forms of acute coronary artery disease 5.4%, alcohol-associated diseases 4.8%. Acute MI ranked 6^th among deaths in general - 2.7%. PCD is also associated with the place of issue of the MDCs - 90% of the MDC with the indication of EI and «other degenerative diseases of the nervous system» as the cause of death were issued by the BFME. Not a single MDC issued by the BFME contained such PCDs as "old age" or "brain cyst".

CONCLUSION

The nosological structure of the causes of death and the issuance of individual ICD codes in the MDC as a PCD varies significantly depending on the place of death and the issuance of the MDC. The reasons need to be further clarified. The use of codes that are not permitted for use has been registered.
