Causes of Death in Patients Asking for Polyclinic Care for Coronary Heart Disease.

AIM: Retrospective analysis of the underlying causes for death of patients who did and did not seek outpatient medical care (OPMC) for ischemic heart disease (IHD), and discussion of a possibility for using administrative anonymized but individualized databases for analysis. MATERIAL AND METHODS: The electronic database of the Central Administration of the Civil Registry Office of the Moscow Region (Unified State Register of the Civil Registry Office of the Moscow Region), including medical death certificates (MDC) for 2021, was used to select all cases of fatal outcomes with the disease codes of the International Classification of Diseases, Tenth Revision (ICD-10) (codes of external causes, injuries, poisonings excluded) that were indicated as the primary cause of death (PCD). Personalized data of the deceased were combined with data from electronic medical records of patients who sought OPMC at institutions of the Moscow Region within up to 2 years before death. In addition to IHD, the following PCD codes were taken into account: malignant tumors, COVID-19, diabetes mellitus, cerebrovascular diseases, hypertension, chronic obstructive pulmonary disease, alcohol-associated diseases, and, as examples of unspecified PCD, old age and unspecified encephalopathy.Results In total, among those who died from diseases, the proportion of those who died from IHD was 18.9%; for another 8.4%, IHD was indicated as a comorbid disease in Part II of the MDC. Among those who sought OPMC for IHD, the IHD proportion indicated as PCD was 27.5%, and among those who did not seek OPMC 17.4% (p <0.0001). Those who died from IHD and who had sought OPMC were older (mean age, 75.59 ± 10.94 years) than those who died from IHD and had not sought OMPM (mean age, 73.96 ± 10.94 years; p < 0.0001). The frequency of myocardial infarction as PCD among those who had and had not sought OPMC was the same (12%), chronic forms of IHD were 83.9% and 79.7%, the frequencies of "unspecified" acute forms of IHD (codes I24.8-9) were 4.1% and 8.3%, respectively. The proportion of deaths from COVID-19 was the highest (21.7% and 24.3%, respectively), from malignant neoplasms 11.6% and 12.7%, respectively, and from unspecified encephalopathy 10.6% and 10.7%, respectively. CONCLUSION: Only 25% of patients who had sought OPMC for IHD died from IHD, otherwise the causes of death were the same as for patients who had not sought OPMC for IHD. Analysis of administrative databases allows identifying disparities in the PCD structure and to direct the efforts of specialists to reconciling the criteria for death from various forms of IHD.

[Diseases of the nervous system as the underlying cause of death]. / Bolezni nervnoi sistemy kak pervonachal'naya prichina smerti.

OBJECTIVE: To identify the leading causes of death in the adult population from the class of diseases of the nervous system (DNS, class G) according to medical death certificates (MDC) and to discuss the problems of their assessment. MATERIAL AND METHODS: The source of information was the electronic database of the Main Department of the Civil Registry Office of the Moscow Region. All cases of class G deaths were selected (total 10.739), an analysis was carried out according to underlying cause of death (UCD) codes and the immediate cause of death. RESULTS: In 2022, mortality from diseases included in the DNS amounted to 130.7 per 100 000 of the population over 18 years old (100.3 among men, 191.0 among women). The average age of men is 74.3±14.1, women - 83.5±9.9 years (p<0.0001) due to the younger age of death of men from «G31.2 Degeneration of the nervous system caused by alcohol¼ and a higher contribution of this cause to male mortality; 82.5% of deaths were for codes G90-G99 («Other disorders of the nervous system¼); 15.5% were neurodegenerative diseases (G10-G32). Sixty-six percent of all UCD in both women and men accounted for «unspecified encephalopathy¼ (G93.4), in 2nd place (10.5%) was «cerebral cyst¼ (G93.0). In 45 cases, code G93.6 (cerebral edema) was mistakenly used as UCD. Differences in the structure of causes of death at home, in hospital and elsewhere are statistically significant (p<0.00001). In 58.3%, cerebral edema and herniation were indicated as the immediate cause of death (G93.6 and G93.5). CONCLUSIONS: Nosologically unfounded, insufficiently well-defined UCD were established in most cases of death from DNS, In 0.5% of the total number of deaths from DNS, an erroneous presentation as UCD of transient disorders of cerebral circulation or cerebral edema was noted. The results indicate the need for an analysis of the causes of death based on a comparison of medical records and MDC.

[Causes of death in the Moscow region according to medical death certificates]. / Prichiny smerti v Moskovskoi oblasti po dannym meditsinskikh svidetel'stv o smerti.

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 6th 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 system¼ 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.

[The characteristics of morbidity of population older than able-bodied age in the Russian Federation in 2012-2018].

The indices of population health exhibit tendency to deteriorate with age. The high level of morbidity, prevalence of chronic diseases, polymorbidity, atypical course of disease, continuous rehabilitation period, frequent complications and exacerbations are specific for individuals over able-bodied age. The purpose of study is to analyze dynamic, structure and characteristics of morbidity of population over able-bodied age in the Russian Federation. The study established specific features in dynamics and structure of morbidity of elderly population during 2012-2018. They are associated with high prevalence of cardiovascular diseases, diseases of musculoskeletal system and connective tissue. Furthermore, there is variety in morbidity rates of neoplasms, endocrine, nutritional and metabolic diseases, mental and behavioral disorders, diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism, diseases of the eye and adnexa, diseases of ear and mastoid process and also symptoms, signs and abnormal clinical and laboratory findings, not classified in other rubrics. The analysis of indices of primary and common morbidity of pneumonia in elderly population of different regions of the Russian Federation was carried out.

REGIONAL TRENDS IN THE WORKING-AGE POPULATION MORTALITY RATE IN THE REPUBLIC OF SAKHA (YAKUTIA) IN 1990-2012.

Regions of the Russian Federation differ in climatic-geographic, medical-demographic and social-economic situations. One of the regions with distinct peculiarities is the Republic of Sakha (Yakutia). Ranking first by the territory (3,103.2 thousand sq x km), Yakutia is on the 81th place by the population density among regions of the Russian Federation (0.3 people per 1 km2).Yakutia is one of the most isolated and inaccessible regions of the world: 90% of the territory lacks all-the-year-round transportation. Regions of the republic, as well, differ significantly in the climatic conditions and the levels of social-economic development, which influences the population health indicators, including mortality. This survey aimed to study the trends of mortality in the working-age population in different groups of regions. To do this, basing on the statistical data, we compared the levels, trends and structure of mortality in 1990-2012. It was established that the different groups of regions show a significant variation in the working-age population mortality, depending on the social-economic conditions. Since 2000, the Arctic group of regions has demonstrated higher mortality in working-age men and women, especially of cardiovascular and digestive system diseases, and external causes. Lying beyond the Arctic Circle, these regions have severe conditions and a relatively low level of social-economic development. As for the rural regions, despite the relatively favourabe situation, they also show a high level of mortality of external causes. The industrial regions are characterized by higher social-economic development, better transport infrastructure, a satisfactory material base of medical institutions. They also have sufficient resources of health institutions, including the staff and modern equipment for treatment and diagnostics, as well as, which is critical, the full range of medical specialists. Thus, these regions demonstrate lower population mortality; however, there is still mortality of infectious diseases, neoplasms, and respiratory diseases.

[Official statistics on urological morbidity in the Russian Federation].

Official medical statistics have been analysed corcerning overall urological morbidity in the Russian Federation (RF) and in some particular regions of the RF. The analysis covered morbidity and mortality from urogenital diseases including glomerular, tubulointersticial and other diseases of the kidneys and ureter, prostatic diseases, male infertility, cancer of the urinary bladder and prostatic gland. It was found that information on urological and oncourological morbidity in the literature is available but its amount is not satisfactory. It is necessary to introduce innovations in organization of medical statistical service, in registration of urological diseases, in particular. Active screening for urological cancer in the RF does not meet requirements and potentialities of modern health care. Special screening programs must be designed to reduce mortality and improve follow-up of urological patients.

[The problems of diagnostics, treatment and prevention arrangement in patients of therapeutic profile].

The recent data research from many countries demonstrates that severe and sometime irreversible complications as a result of inadequate manipulations of physicians affect hundreds of thousands of people. The defects of treatment are more obvious in surgery than in therapy. To qualify the manipulations of the therapist as proper or non-proper is much more difficult as compared with erroneous conclusion in diagnostics. Underestimation and belated resolution of this issue is fraught with the most grave consequences.

[Surgery in 1993-2002].

Analyzed in the paper are volumes and structure of surgery in 1993-2002. It is shown that the fluctuating and mismatching nature of surgical up trend observed both in hospitals and outpatient clinics contradicts the redistribution of scope of medical care in favor of its primary stage, which is not supported up to now by an appropriate personnel policy.

[Standardization and its importance in rendering medical care to patients with cancer of the bladder]. / Rol' standartizatsii v uluchshenii organizatsii pomoshchi bol'nym rakom mochevogo puzyria.

There are only as many as 31 specialized oncourological departments in 24 of 89 (27%) Federation Subjects in the Russian Federation that can render the oncourological care at the municipal and federal levels. As for other remaining 65 (73%) Subjects, the urologists are preoccupied with diagnosis and treatment of urinary-bladder cancer in them. Russian patient-care facilities have presently differing opportunities in the sphere of diagnosis and treatment of the mentioned pathology. Their related outfit for this purpose is on the whole unsatisfactory. An optimal management of medical care rendered to the discussed category of patients and targeted at promoting its quality and efficiency is possible only on the basis of standardization of diagnostic and treatment approaches. The stage-nature of medical care rendered to such patients is closely related the standardization issues. An accurate definition of stages and of patient-care facilities, which would be in charge for the above stages, would, in the end, clearly depict a sequence of steps for the diagnostic-and-therapeutic schemes applicable to patients with cancer of the urinary bladder. This, in its turn, would optimize the diagnostic-and-therapeutic process and outline the priority spheres in healthcare financing.

[Organization of care for patients with urinary bladder cancer in the Russian Federation and approaches to its improvement based on standardization of a diagnostic and therapeutic process]. / Organizatsiia pomoshchi bol'nym rakom mochevogo puzyria v Rossiiskoi Federatsii i puti ee uluchsheniia na osnove standartizatsii lechebno-diagnosticheskogo protsessa.

Present-day medical facilities for treating patients with cancer of the urinary bladder in the Russian Federation (RF) are insufficient. In 1998, urological cancer in RF was managed only in 31 specialized departments working in 24 of 89 (27%) administrative units of the RF. In the other 65 (73%) units only urologists deal with diagnosis and treatment of urinary bladder cancer. These nonspecialized departments lack special equipment and personnel. Therefore, effective management and organization of medical care for urinary bladder cancer can be achieved on the basis of standardization of diagnostic and therapeutic methods and definition of stages in treatment policy. This helps to outline priorities in financing health services.
