The concept of frailty syndrome (FS) was first described in the scientific literature three decades ago. For a very long time, we understood it as a geriatric problem, recently becoming one of the dominant concepts in cardiology. It identifies symptoms of FS in one in 10 elderly people. It is estimated that in Europe, 17% of elderly people have FS. The changes in FS resemble and often overlap with changes associated with the physiological aging process of the body. Although there are numerous scientific reports confirming that FS is age correlated, it is not an unavoidable part of the aging process and does not apply only to the elderly. FS is a reversible clinical condition. To maximize benefits of frailty-reversing activities for patient with frailty, identification of its determinants appears to be fundamental. Many of the determinants of the FS have already been known: reduction in physical activity, malnutrition, sarcopenia, polypharmacy, depressive symptom, cognitive disorders, and lack of social support. This review shows that insight into FS determinants is the starting point for building both the comprehensive definition of FS and the adoption of the assessment method of FS, and then successful clinical management.

Efforts to limit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections among hospital healthcare staff are crucial for controlling the Coronavirus Disease 19 (COVID-19) pandemics. The study aimed to explore the prevalence and clinical presentations of COVID-19 in healthcare workers (HCWs) at the University Clinical Hospital (UCH) in Wroclaw with 1677 beds. The retrospective study was performed in 2020 using a self-derived structured questionnaire in a sample of HCWs who were diagnosed with SARS-CoV-2 infection confirmed using a PCR double gene test and consented to be enrolled into the study. The significance level for all statistical tests was set to 0.05. The study showed that of the 4998 hospital workers, among 356 cases reported as COVID-19 infected, 70 consented to take part in the survey: nurses (48.5%), doctors (17.1%), HCWs with patient contact (10.0%), other HCWs without patient contact (7.1%), and cleaning personnel (5.7%). HCWs reported concurrent diseases such as hypertension (17.1%), bronchial asthma (5.7%), and diabetes (5.7%). Failure to keep 2 m distancing during contact (65.5%) and close contact with the infected person 14 days before the onset of symptoms or collection of biological material (58.6%) were identified as the increased risks of infection. A large part of infections in hospital healthcare staff were symptomatic (42.9%). The first symptoms of COVID-19 were general weakness (42.9%), poor mental condition (41.4%), and muscle pain (32.9%); whereas in the later stages of the illness, general weakness (38.6%), coughing (34.3%), lack of appetite (31.4%), and loss of taste (31.4%) were observed. In about 30% of the infected HCWs, there was no COVID-19 symptoms whatsoever. The vast majority of the patients were treated at home (85.7%). In conclusion, the majority of the SARS-CoV-2 infections in the hospital HCWs were asymptomatic or mildly symptomatic. Therefore, successful limitation of COVID-19 infection spread at hospitals requires a close attention to future cross-infections.

Introduction: In a long-term approach to the treatment of heart failure, importance is given to the process of self-care management and behaviors. The number of rehospitalizations and unscheduled medical visits can be reduced by actively engaging patients in the self-care process. Methods: The study included 403 patients with chronic heart failure (mean LVEF 40.53%), hospitalized in the Cardiology Department. Medical record analysis and a self-report questionnaire were used to obtain basic sociodemographic and clinical data. The European Heart Failure Self-care Behavior Scale, revised into a nine-item scale (EHFScBS-9), was used to evaluate self-care behavior. Results: Analysis of the EHFSc-9 self-care behavior scale showed that the mean score was 49.55 out of 100 possible points (SD = 22.07). Univariate analysis revealed that significant (p < 0.05) negative predictors of the EHFScB-9 self-care scale included: male sex (b = −5146), hospitalizations in the last year (b = −5488), NYHA class II (b = −11,797) and NYHA IV class (b = −15,196). The multivariate linear regression model showed that a significant (p ˂ 0.05) negative predictor of the EHFScB-9 self-care scale was male sex (b = −5.575). Conclusions: Patients with chronic HF achieve near optimal self-care behavior outcomes. A patient prepared to engage with self-care will have fewer rehospitalizations and a better quality of life.

Introduction: The aging of modern societies increases the general healthcare burden due to the growing demand for inpatient services, which lack adequate financing. Material and methods: Data concerning the costs of 312,250 hospitalizations at University Clinical Hospital in Wrocław, Poland in the years 2012-2015 were analyzed according to the age of the patients: below 65 years and 65 years and older, with subgroups (65-74, 75-84 and 85 years and older). Results: The mean length of stay (LOS) differed significantly for patients below 65 years and for patients 65 years old or older (3.5 vs. 4.7 person-days); over the 4 years covered by our data, these increased by 0.4 person-days, mostly among patients 85 years and older (by 0.7 person-days). The mean direct cost of hospitalization differed significantly for patients below 65 years and those 65 years or older (PLN 4,907.12 vs. PLN 6,357.15). The mean cost of laboratory tests and radiologic diagnostics was significantly higher among those in the 65+ group, and the difference had a rising trend. The differences between age groups in cost-related hospitalization characteristics and direct hospitalization costs that have been suggested by the medical literature have also been confirmed in Poland. Conclusions: The mean hospitalization costs of patients aged 65 years and older in Poland are higher than for younger patients due to longer LOS and more complex and expensive treatment, especially laboratory and radiologic diagnostics, which is increasingly common in the oldest age groups. This demands an urgent systemic solution, especially in terms of adjusted financing of elderly patients' hospital treatment.

Frailty syndrome (FS) often coexists with many diseases of the elderly, including arterial hypertension, and may affect the disease course and adherence to therapeutic recommendations. This study aimed to evaluate the relationship between frailty and adherence to therapeutic recommendations in elderly hypertensive patients. The study included 259 patients hospitalized between January 2019 and November 2020 due to exacerbation of hypertension symptoms. Medical records were used to obtain basic sociodemographic and clinical data. The study was based on the Tilburg Frailty Indicator (TFI) and the Hill–Bone Scale (HBCS). The obtained data were analyzed within a cross-sectional design. The mean frailty score indicated by the TFI questionnaire was 7.09 ± 3.73. The most prominent FS component was associated with the physical domain (4.24 ± 2.54). The mean overall adherence measured with the HBCS was 20.51 ± 3.72. The linear regression model testing the Hill–Bone “reduced sodium intake” score against the TFI domains showed no relationships between the variables. Another regression model for the Hill–Bone “appointment-keeping” subscale indicated significant predictors for physical and social TFI domains (p = 0.002 and p < 0.0001, respectively). For the Hill–Bone “taking antihypertensive drugs” variable, the regression model found significant relationships with all TFI domains: physical (p < 0.0001), psychological (p = 0.003) and social (p < 0.0001). Our study suggests that frailty in patients with arterial hypertension can negatively impact their adherence to therapeutic recommendations.
