Falls predict functional status declines in old age and institutionalization. Among the causes of the falls are sensory deficits, cognitive impairment, chronic diseases such as cardiovascular, endocrine diseases, musculoskeletal system pathology, the use of sedatives, antihypertensive drugs, neuroleptics and diuretics, as well as external causes, including inappropriate aids. The optimal diagnostic method in this case is a comprehensive geriatric assessment, which allows for focused history taking, detailing the circumstances of the fall, identification of risk factors and assessment of consequences, the gait and balance testing, determination of the lower limbs and joints functions are hold in the course of CGA along with orthostatic test that detects sensory deficits. Additional measures of mandatory recommendations should be a discussion of rational nutrition, with an emphasis on adequate intake of protein with food and fluids as prevention.

The prevalence of in-hospital falls varies depending on medical institution profile and department. According to various sources, the incidence of falls in intensive care units (ICU) is 2.3-7 falls per 1000 bed-days (a day spent by a person in the hospital). Assessment of fall risk in elderly patients shows that especially in case of deteriorating health, after transfer to another department, and when the fall has already happened, according to the protocol nurses will allow quickly identification of the problem and provide timely correction.

Objective. Evaluation of influence on mortality, life expectancy and related costs in the Russian Federation of methodical changes in the organizing surgical treatment of proximal femur fracture (PFF).Material and methods. The mathematical modeling methods were applied for evaluation of impacts, related to methodical changes in the organizing surgical treatment of PFF, including the calculation of life expectancy. It is assumed, that 95% of all patients over 60 years old with PFF would receive a surgical treatment. Calculations were perform in 3 stages: calculation of death causes, related to PFF, calculation of life expectancy change in population and calculation of direct and indirect medical and non-medical costs and social assistance for patients with PFF.Results. Mortality rate from PFF in model is decreased by 51%, which is equal to 55 648 saved lives. Life expectancy indicator increases by 0.3 annually during the transition to new methods of surgical treatment for the patients with PFF. Number of disabled patients is decreasing by 74 179 people annually. Taking into account all the effects, revealed in the modeling, the financial savings are estimated at 12.3 billion rubles or 32% of current expenditures from all funding sources on treatment and social assistance of patients with PFF.Conclusion. Implementation of this new approach to surgical treatment of patients over 60 years old with PFF shows a positive influence on dynamic of demographical indicators of population in general. Despite changes in structure of expenses and increase direct medical costs, new approach in surgical care will lead to a major cost reduction as well as significant improvement of treatment results for geriatric patients with PFF.

On behalf of EVKALIPT study.Objective: to evaluate prevalence of age-related and chronic non-infectious diseases, senile asthenia and other geriatric syndromes in subjects aged ≥65 years old and to analyze their influence on general health and functional status.Methods: 4308 subjects (30% males) aged from 65 to 107 years (mean age 78±8 years), who live in 11 Russian regions, were examined. They were divided in 3 groups by age: 65–74, 75–84 and ≥85 years. All subjects passed comprehensive geriatric assessment in 2 stages: 1) questioning based on a specially designed questionnaire; 2) physical examination.Results: age increase is associated with decrease of anthropometric parameters (height, weight, body mass index), decrease of diastolic blood pressure, increase of pulse blood pressure and deterioration of social-economic status of elderlies (increase of those who out lived their partners, living alone and in institution/ nursing home, single (no partners) and disabled subjects; decrease in proportion of married and still working ones, subjects with university degree and higher income).Conclusion: Russian EVKALIPT study protocol and basic characteristics of participants are summarized in the article.

Treatment of osteoarthritis, as the most common pathology of the musculoskeletal system, presents certain clinical difficulties in comorbid patients. The frequent combination of osteoarthritis (OA) and cardiovascular diseases (CVD), diabetes mellitus type 2 and other cardiometabolic pathologies raises questions about the safety of pain relievers in the presence of chronic kidney disease (CKD). Safe treatment for chronic pain syndrome implies an informed decision about the risks / benefits of using any analgesic intervention. Particular attention should be paid to the decision on the appointment of non-steroidal anti-inflammatory drugs (NSAIDs). An alternative strategy for the treatment of joint pain in patients with CKD may be the use of chondroitin sulfate prescription form. Particular attention should be paid to the possibility of using the parenteral form of the drug, which has reliable evidence, faster onset of the clinical effect of analgesia, with a potential protective effect on the structure of joint tissues.

Aim. To analyze the factors associated with the development of chronic heart failure (CHF) in older age and to evaluate possible approaches to managing outpatients.Material and methods. The search for domestic and foreign publications in Russian and international systems (PubMed, eLibrary, Medscape, etc.) for the last 0.5–15 years has been carried out. The analysis includes articles from the peer-reviewed literature.Results. During aging, a number of structural changes and changes at the cellular level occur in the cardiovascular system, predisposing to the development of myocardial dysfunction, which explains the variety of manifestations of heart failure and the prevalence of preserved left ventricular ejection fraction (LVEF). Involutional functional and morphological changes in organs and systems form multimorbidity and nonspecificity of clinical symptoms and signs. «Cross symptoms» of frailty and CHF often complicate the timely diagnosis of the heart failure. Medications used for the treatment of CHF in older and younger patients are similar, but when choosing a specific drug, caution should be exercised in the group of the most vulnerable patients: over the age of 85, in the first two weeks after discharge from the hospital and in the presence of frailty.Conclusion. Based on the available results of studies, it is necessary to be alert of primary care physicians regarding the presence of CHF with preserved LVEF in older persons with multimorbidity and geriatric syndromes. The therapeutic strategy for CHF older patients is complex and involves an individualized approach, depending on the clinical situation.
