Mortality in clostridioides difficile infection among patients hospitalized at the university clinical hospital in Wroclaw, Poland - a 3-year observational study.

BACKGROUND: In the last two decades, a significant increase in the number of Clostridioides difficile infection (CDI) cases has been observed. It is understandable to attempt to determine the factors that can predict the severity of the course of the infection and identify patients at risk of death. This study aimed to analyze the factors affecting the incidence and mortality of CDI in inpatient treatment at the University Clinical Hospital in Wroclaw in 2016-2018. METHODS: Statistical analysis of data obtained from patients' medical records was performed. Only patients with symptoms of infection and infection confirmed by laboratory tests were enrolled in the study. When analyzing the number of deaths, only adult patients who died in hospital wards were included. The quantitative data including laboratory tests, used antibiotics and Nutritional Risk Screening (NRS) were assessed. Also, the qualitative data such as sex, year of hospitalization, occurrence of diarrhoea on admission to the hospital, presence of additional diseases, as wee ad the use of antibacterial drugs or proton pump blockers and ranitidine during hospitalization were analyzed. RESULTS: A total of 319 adult CDI patients (178 women and 141 men) were enrolled of which 80 people died (50 women and 30 men). The mean age of the patients was 72.08 ± 16.74 years. Over the entire period studied, the morbidity was 174 cases per 100,000 hospitalizations while mortality was 25.08%. The group of deceased patients was characterized by: older age (by 9.24 years), longer duration of hospitalization (by 10 days), reduced albumin levels (Rho = -0.235, p < 0.001), higher urea levels, use of more antibiotics, higher risk of malnutrition in NRS (Rho = 0.219, p < 0.001), higher incidence of sepsis, heart failure, stroke, hypothyroidism. Pneumonia was diagnosed twice as often. It was also shown that deceased patients were significantly more likely to take penicillin and fluoroquinolones. CONCLUSIONS: In this study, the morbidity was lower, but mortality was higher compared to similar hospitals in Poland. CDI patients were characterized by older age, multimorbidity, extended hospitalization, and the use of broad-spectrum antibiotics. Risk factors for death included advanced age, prolonged hospital stays, lower albumin, higher urea, malnutrition, and comorbidities like heart failure, stroke, pneumonia, sepsis, and hypothyroidism. Increased antibiotic use, particularly penicillin and fluoroquinolones, was associated with a higher mortality risk.

Pain and symptoms of depression: international comparative study on selected factors affecting the quality of life of elderly people residing in institutions in Europe.

BACKGROUND: As the number of elderly people is on the rise in societies throughout the world, providing them with optimal care is becoming a major demand, especially in the context of rising interest in institutional care. Quality of life is multidimensional notion and its perception depends highly on pain and mood levels. The aim of this study was to perform a comparative analysis of pain and depression symptoms in elderly people living in nursing homes in France, Germany, and Poland. METHODS: The research carried out in years 2014-2016 involved female residents of nursing homes in France, Germany, and Poland: 190 women from each country, aged over 65 years and not previously diagnosed with advanced dementia, were included. Collection of medical, demographic, and anthropomorphic data from medical documentation was followed by interviews with each senior and her caregiver. A questionnaire of authors' own devising was used, along with the Beck Depression Inventory (BDI) and the scale of Behavioral Pain Assessment in the Elderly (DOLOPLUS). The results were subjected to statistical analysis, p < 0.05 was accepted as threshold of statistical significance. RESULTS: The main health complaints of nursing homes' residents were constipation, diarrhea, back pain and dizziness. 44,38% of the residents self-assessed their health status as bad and complained of suffering pain (83,33%) and sleeping problems (72,98%) within the last month. According to BDI the average score was 17.01 points and 44,38% of seniors were free from depression or depressed mood. The average DOLOPLUS result was 8.86 points. CONCLUSION: There are no significant differences, neither in prevalence of pain and symptoms of depression nor in average levels of quality of life, in elderly residents in institutions in the three studied European countries. The decrease in quality of life is mainly due to various complaints and pain and there is a close relationship between health status and quality of life. Further research should be performed in order to study interdependencies between the occurrence of pain and depression, including primary reasons leading to both phenomena. The recognition of factors that induce pain complaints and mood depression in elderly people will contribute to improving their comfort.

Differences in selected medical care parameters in rheumatic disease ward patients of different ages of life.

INTRODUCTION: Rheumatic diseases are becoming more and more common in Poland with the ageing of the population. Nearly 18% of the total hospital admissions in Poland result from rheumatic diseases, which was equivalent to 350 thousand cases in the year 2008. These diseases tend to last for many decades, decreasing both the quality of life and income of the patients as well as increasing the medical institutions' workload and society's financial burden. The aim of the study was to determine whether the medical care parameters in a rheumatic disease hospital ward show any significant differences among different patient age groups - especially such that would support taking them into account as a basis for adjusting the financial coverage level of medical services. MATERIAL AND METHODS: Data on hospitalizations at the Rheumatic Diseases Ward of Wroclaw University Hospital in Wroclaw in the years 2009-2015 were analyzed, taking into account the age groups, number of hospital admissions, their duration and causes. Relevant statistical data analysis was performed. DISCUSSION: The study revealed that the number of old patients hospitalized at the rheumatic diseases ward increased over the last 6 years and that such statistically significant differences do exist: on average the old patients not only tend to stay much longer at the hospital, but also suffer from a different and more diverse spectrum of diseases in comparison to their younger counterparts. CONCLUSIONS: The detected differences in medical care parameters support the need for more individualized medical care and increased cost of the hospital stay in the case of older patients. Consequently, those factors justify the necessity to increase the value of medical services in the case of old patients, possibly also taking into account the variation between age subgroups.

Ondine's Curse - Genetic and Iatrogenic Central Hypoventilation as Diagnostic Options in Forensic Medicine.

In the Nordic mythology a man lost his ability to breathe without remembering it after he was cursed by water nymph - referred to as 'Ondine's curse' - and then he died as soon as he fell asleep. Family medicine specialists are familiar with many sleeping disorders that their patients commonly call by the term Ondine's Curse. In medical sciences this term is historically related to the group of conditions that have as the common denominator seemingly spontaneous onset of life-threatening hypoventilation. The physiology and genetics specialists focus mainly on congenital central hypoventilation syndrome (CCHS), which was proven to be linked to several genetic mutations. Anesthesiologists tend to be more interested in similarly manifesting iatrogenic condition. Typically, patients that were previously subjected to general anesthesia, after temporarily waking up and regaining the spontaneous respiratory drive, later fall back into unconsciousness and develop hypoventilation. Anesthesiologists also call it Ondine's curse because of the sudden and unexpected sleep onset. The iatrogenic Ondine's curse is proven to be precipitated by delayed anesthetics release from patients' fat tissue - where it was deposited at the time general anesthesia was administered - back into bloodstream. Forensic medicine has to consider the latter form of Ondine's curse called scenario more often, as they investigate sudden deaths related to surgery and general anesthesia in the post-operational care period. These cases may also fall into the category of medical malpractice-related deaths.

Analysis of factors affecting the length of hospitalization of patients with Clostridioides difficile infection: a cross-sectional study.

BACKGROUND: Clostridioides difficile infection (CDI) is an infectious disease caused by the gram-positive, anaerobic bacterium C. difficile. The vulnerable populations for CDI include the elderly, immunocompromised individuals, and hospitalized patients, especially those undergoing antimicrobial therapy, which is a significant risk factor for this infection. Due to its complications and increased resistance to treatment, CDI often leads to longer hospital stays. This study aimed to determine the average length of hospital stay (LOS) of Polish patients with CDI and to identify factors affecting the LOS of infected patients. METHODS: The study analyzed medical records of adult patients treated with CDI in one of the biggest clinical hospitals in Poland between 2016-2018. Information encompassed the patient's age, LOS results of selected laboratory tests, number of antibiotics used, nutritional status based on Nutritional Risk Screening (NRS 2002), year of hospitalization, presence of diarrhea on admission, systemic infections, additional conditions, and undergone therapies. The systematic collection of these variables forms the foundation for a comprehensive analysis of factors influencing the length of stay. RESULTS: In the study period, 319 patients with CDI were hospitalized, with a median LOS of 24 days (min-max = 2-344 days). The average LOS was 4.74 days in 2016 (median = 28 days), 4.27 days in 2017 (median = 24 days), and 4.25 days in 2018 (median = 23 days). There was a weak negative correlation (Rho = -0.235, p < 0.001) between albumin level and LOS and a weak positive correlation between NRS and LOS (Rho = 0.219, p < 0.001). Patients admitted with diarrhea, a history of stroke or pneumonia, those taking certain antibiotics (penicillins, cephalosporins, carbapenems, fluoroquinolones, aminoglycosides, colistin), and those using proton pump inhibitors, exhibited longer hospitalizations (all p < 0.001) or unfortunately died (p = 0.008). None of the individual predictors such as albumin level, Nutritional Risk Screen, pneumonia, stroke, and age showed a statistically significant relationship with the LOS (p > 0.05). However, the multivariate regression model explained a substantial portion of the variance in hospitalization length, with an R-squared value of 0.844. CONCLUSIONS: Hospitalization of a patient with CDI is long. Low albumin levels and increased risk of malnutrition were observed in longer hospitalized patients. Longer hospitalized patients had pneumonia, stroke, or surgery, and were admitted for a reason other than CDI.

Effective microorganism water treatment method for rapid eutrophic reservoir restoration.

Since reservoirs perform many important functions, they are exposed to various types of unfavorable phenomena, e.g., eutrophication which leads to a rapid growth of algae (blooms) that degrade water quality. One of the solutions to combat phytoplankton blooms are effective microorganisms (EM). The study aims to evaluate the potential of EM in improving the water quality of the Turawa reservoir on the Mala Panew River in Poland. It is one of the first studies providing insights into the effectiveness of using EM in the bioremediation of water in a eutrophic reservoir. Samples for the study were collected in 2019-2021. The analysis showed that EM could be one of the most effective methods for cleaning water from unfavorable microorganisms (HBN22, HBN36, CBN, FCBN, FEN) - after the application of EM, a reduction in their concentration was observed (from 46.44 to 58.38% on average). The duration of their effect ranged from 17.6 to 34.1 days. The application of EM improved the trophic status of the Turawa reservoir, expressed by the Carlson index, by 7.78%. As shown in the literature review, the use of other methods of water purification (e.g., constructed wetlands, floating beds, or intermittent aeration) leads to an increase in the effectiveness and a prolongation of the duration of the EM action. The findings of the study might serve as a guide for the restoration of eutrophic reservoirs by supporting sustainable management of water resources. Nevertheless, further research should be conducted on the effectiveness of EM and their application in the remediation of eutrophic water reservoirs.

Migration Challenges and Their Impact on the Primary Healthcare System-A Qualitative Research.

In 2020 it is estimated that 281 million people were international migrants. Migrants constitute a potentially vulnerable population in terms of facing discrimination, poor living and housing conditions, and insufficient access to healthcare services. Due to the armed conflict in Ukraine in 2022, almost 10 million people crossed the Polish border within a year of the outbreak of the conflict. The objective of this paper is to present the use of primary healthcare services by people migrating from Ukraine to Poland and identify the barriers in access to healthcare by this group of persons. This study used a qualitative research technique in the form of an expert interview using individual in-depth interviews (IDI). The study group consisted of professionally active primary healthcare providers (doctors, nurses, and facility managers) in Poland. Research was carried out in the areas regarding the availability of healthcare, the potential threats and challenges, and possible system solutions. The results showed that the most common cause for doctor's appointments among migrants are respiratory infections, including COVID-19. Many cases were related to back pain, mainly resulting from the physical work of the patients. Additionally, some barriers to access and the provision of healthcare services for patients from Ukraine were identified. The majority (75%) of respondents indicated language as a significant barrier when providing services. Based on the study results, we recommend creating a dedicated website and telephone hotline for this group of persons as well as the use of traditional media to distribute information about access to healthcare services. It is also essential to focus on assistance for older people, since they may experience more difficulties with language and navigating the healthcare system.

Lung Cancer Screening-Trends and Current Studies.

Lung cancer is the leading cause of death among all the oncological diseases worldwide. This applies to both women and men; however, the incidence and mortality among women is on the rise. In 2020, lung cancer was responsible for 1.8 million deaths (18%). More than 90% of lung cancer cases and 77.1% of lung cancer deaths occur in countries with high and very high HDI (human development index) values. The aim of our study is to the present trends and most recent studies aimed at lung cancer screening. In the face of the persistently high mortality rate, conducting research aimed at extending already-implemented diagnostic algorithms and behavioural interventions focused on smoking cessation is recommended.

Measuring the Intensity of Stress Experienced and Its Impact on Life in Patients with Diagnosed Alcohol Use Disorder.

Alcohol addiction is characterized by extensive alcohol consumption that dominates other behaviours previously important to a patient. According to data from The State Agency for Prevention of Alcohol-Related Problems, up to 900,000 people in Poland are addicted to alcohol. On average, approximately 9.7 L of pure alcohol per capita was consumed in 2021. Alcohol addiction may cause severe health problems and is one the key risk factors for various diseases. Stress plays an important role in the process of alcohol addiction and is also a predictor for lower enjoyment in life. On the other hand, sense of coherence may be a stronger protective factor. The aim of our study was to verify the relation between the level of perceived stress among patients with alcohol addiction and satisfaction with life. Because sense of coherence is a disposition that allows for managing stress effectively, the latter should be reflected in the results of multivariate analyses that take both the level of stress and sense of coherence into account. In the present study, sense of coherence and perceived stress were negatively correlated; therefore, strengthening internal resources for managing difficult and stressful situations is recommended.

Influenza as an important factor causing increased risk of patients' deaths, excessive morbidity and prolonged hospital stays.

Introduction: Influenza infection is associated with potential serious complications, increased hospitalization rates and a higher risk of death. Material and methods: A retrospective comparative analysis of selected indicators of hospitalization at the University Hospital in Wroclaw was conducted on patients with confirmed influenza infection and a control group during the 2018-2019 influenza season. The threshold for statistical significance of differences between the groups was set at p < 0.05. Results: The types of influenza viruses confirmed in the hospital patients were remarkably similar to those occurring in the general population in Poland. The largest numbers of influenza cases were observed at the departments related to internal medicine where patients with cardiac, lung and renal diseases were hospitalized. The risk of death among the patients with confirmed influenza infection was significantly higher than among the other patients. The highest risk of death was observed among the patients with confirmed influenza infection at the departments related to internal medicine. Considering patients from the entire hospital, the mean length of hospital stay for those with confirmed influenza was 2.13-fold longer than for those in the control group. Comparisons of the median, minimum and maximum lengths of hospitalization between the patients with confirmed influenza infection and the control group reveal even more distinct differences. Conclusions: Significant differences in the selected indicators of hospitalization were observed between the patients with confirmed influenza infection and the control group; they are associated with serious social costs, such as prolonged hospital stay and a higher risk of death during hospitalization in Poland.

Overview of Pancreatic Cancer Epidemiology in Europe and Recommendations for Screening in High-Risk Populations.

Pancreatic cancer is the seventh most common cause of death in the group of oncological diseases. Due to the asymptomatic course, early diagnosis is difficult. Currently, early detection methods are only used in high-risk groups. A literature review based on the available results of observational studies on patients with pancreatic cancer and people from high-risk groups was used to summarize the knowledge on risk factors. The GLOBOCAN 2020 data were used to assess the epidemiological situation in Europe. A summary of screening recommendations was prepared based on the available documents from medical organizations and associations. Pancreatic cancer risk factors are divided into two main groups: non-modifiable factors, e.g., hereditary factors and age, which increase the risk of developing this disease, and modifiable factors-BMI, smoking, and alcohol consumption. Hereditary factors account for 10% of pancreatic cancer cases. The highly specialized methods of early detection, (MRI, CT, or EUS) are used for screening high-risk populations. Of all the imaging methods, EUS is considered the most sensitive for pancreatic cancer and allows an accurate assessment of the size of even small lesions (<30 mm) and the extent of tumour infiltration into blood vessels. The available studies vary on the level of sensitivity and specificity of these methods for the diagnosis of pancreatic cancer. EUS, MRI, and CT are also expensive procedures and in some patients can be invasive, which is one of the arguments against the introduction of population screening programs based on imaging methods. Therefore, it is important to look for viable solutions that would improve early detection. This is important from the point of view of healthcare systems in Europe, where almost 29% of all global pancreatic cancer cases are reported.

Management of Metastatic Pancreatic Cancer-Comparison of Global Guidelines over the Last 5 Years.

Pancreatic cancer (PC) is usually diagnosed at an advanced stage of its development, which results in lower overall survival (OS). Prognosis is also poor even with curative-intent surgery. Approximately 80% of patients with localized PDAC have micrometastases at the time of diagnosis, which leads to a worse prognosis than in other cancers. The objective of this study is to present the progress in the treatment of metastatic pancreatic cancer based on the recommendations of oncological scientific societies, such as ESMO, NCCN, ASCO, NICE and SEOM, over the last 5 years. Combined FOLFIRINOX therapy is mostly a recommended therapy among patients with good performance statuses, while gemcitabine is recommended for more fragile patients as a first-line treatment. The newest guidelines suggest that molecular profiling of the tumor should be the first step in determining the course of treatment. The use of modern molecular therapies in patients with specific gene mutations should extend the survival of patients with this disease.

Fear of Illness and Convenient Access to Vaccines Appear to Be the Missing Keys to Successful Vaccination Campaigns: Analysis of the Factors Influencing the Decisions of Hospital Staff in Poland concerning Vaccination against Influenza and COVID-19.

The COVID-19 pandemic has lasted for two years as of 2022, and it is common knowledge that vaccines are an essential tool to mitigate the health, economic, and social fallout. Unfortunately, vaccine hesitancy is still a serious global problem, both in the general population and among healthcare workers. The authors used an original questionnaire to conduct an anonymous survey study in the University Clinical Hospital in Wroclaw, Poland, in April and May of 2021 after acquiring consent from the Medical University of Wroclaw, Poland Bioethical Committee. The study results demonstrate that, to a significant extent, the decisions concerning vaccinations are based on factors that are difficult to change with rational argumentation, including people's personal opinions or beliefs concerning vaccinations and their earlier experiences with vaccinations. The study results suggest that the impregnating effect of one's own opinions, beliefs, and experiences can be surmounted if vaccines are dispensed free and conveniently while the pathogen is irrationally and emotionally perceived as untamed and possibly severe and life threatening. It makes a significant difference as in such cases that the percentage of participants whose decisions concerning vaccination are influenced by the risks to life or health of one's own or others rises by about 27 and 36 percent points, respectively. Therefore, in order to succeed, campaigns for vaccinations need to include strong subjective and emotional communication, appealing to negative emotions and exploiting the public's fear of the unknown while stressing tangible and personal threats possibly resulting from acquiring a vaccine-preventable infectious disease.

Perception and Attitude toward Teleconsultations among Different Healthcare Professionals in the Era of the COVID-19 Pandemic.

Teleconsultation has become one of the most important and sometimes the only possible forms of communication between healthcare professionals (HCPs) and their patients during the COVID-19 pandemic. The perceptions and attitudes of HCPs to teleconsultations may affect the quality of the therapeutic process provided using them. Therefore, this study aimed to understand the attitudes to and perceptions of medical teleconsultation among various HCPs during the COVID-19 pandemic. We analyzed data from a dedicated questionnaire on preferences, attitudes, and opinions about teleconsultation, which was filled by 780 Polish HCPs. Most of the HCPs were doctors and nurses (69% and 19%, respectively); most of the doctors were family physicians (50.1%). During the pandemic, teleconsultation and face-to-face contact were reported as the preferred methods of providing medical services with similar frequency. Doctors and nurses displayed the most positive attitude toward teleconsultation while the paramedics and physiotherapists took the least positive view of it. The most frequently indicated ratio of the optimal number of teleconsultations to in-person visits in primary health facilities care was 20%:80%. Most HCPs appreciate the value of teleconsultation, and more than half of them are willing to continue this form of communication with the patient when necessary or desirable.

History of Heart Failure in Patients Hospitalized Due to COVID-19: Relevant Factor of In-Hospital Complications and All-Cause Mortality up to Six Months.

BACKGROUND: Patients with heart failure (HF) are at high risk of unfavorable courses of COVID-19. The aim of this study was to evaluate characteristics and outcomes of COVID-19 patients with HF. METHODS: Data of patients hospitalized in a tertiary hospital in Poland between March 2020 and May 2021 with laboratory-confirmed COVID-19 were analyzed. The study population was divided into a HF group (patients with a history of HF) and a non-HF group. RESULTS: Out of 2184 patients (65 ± 13 years old, 50% male), 12% had a history of HF. Patients from the HF group were older, more often males, had more comorbidities, more often dyspnea, pulmonary and peripheral congestion, inflammation, and end-organ damage biomarkers. HF patients had longer and more complicated hospital stay, with more frequent acute HF development as compared with non-HF. They had significantly higher mortality assessed in hospital (35% vs. 12%) at three (53% vs. 22%) and six months (72% vs. 47%). Of 76 (4%) patients who developed acute HF, 71% died during hospitalization, 79% at three, and 87% at six months. CONCLUSIONS: The history of HF identifies patients with COVID-19 who are at high risk of in-hospital complications and mortality up to six months of follow-up.

Usefulness of C2HEST Score in Predicting Clinical Outcomes of COVID-19 in Heart Failure and Non-Heart-Failure Cohorts.

Background: Patients with heart failure represent a vulnerable population for COVID-19 and are prone to having worse prognoses and higher fatality rates. Still, the clinical course of the infection is dynamic, and complication occurrence in particular in patients with heart failure is fairly unpredictable. Considering that individual components of the C2HEST (C2: Coronary Artery Diseases (CAD)/Chronic obstructive pulmonary disease (COPD); H: Hypertension; E: Elderly (Age ≥ 75); S: Systolic HF; T: Thyroid disease) are parallel to COVID-19 mortality risk factors, we evaluate the predictive value of C2HEST score in patients with heart failure (HF) Material and Methods: The retrospective medical data analysis of 2184 COVID-19 patients hospitalized in the University Hospital in Wroclaw between February 2020 and June 2021 was the basis of the study. The measured outcomes included: in-hospital mortality, 3-month and 6-month all-cause-mortality, non-fatal end of hospitalization, and adverse in-hospital clinical events. Results: The heart failure cohort consists of 255 patients, while 1929 patients were assigned to the non-HF cohort. The in-hospital, 3-month, and 6-month mortality rates were highest in the HF cohort high-risk C2HEST stratum, reaching 38.61%, 53.96%, and 65.36%, respectively. In the non-HF cohort, in-hospital, 3-month, and 6-month mortalities were also highest in the high-risk C2HEST stratum and came to 26.39%, 52.78%, and 65.0%, respectively. An additional point in the C2HEST score increased the total death intensity in 10% of HF subjects (HR 1.100, 95% CI 0.968−1.250 p = 0.143) while in the non-HF cohort, the same value increased by 62.3% (HR 1.623, 95% CI 1.518−1.734 p < 0.0001). Conclusions: The C2HEST score risk in the HF cohort failed to show discriminatory performance in terms of mortality and other clinical adverse outcomes during hospitalization. C2HEST score in the non-HF cohort showed significantly better performance in terms of predicting in-hospital and 6-month mortality and other non-fatal clinical outcomes such as cardiovascular events (myocardial injury, acute heart failure, myocardial infarction, cardiogenic shock), pneumonia, sepsis, and acute renal injury.

Seasonal Influenza and Low Flu Vaccination Coverage as Important Factors Modifying the Costs and Availability of Hospital Services in Poland: A Retrospective Comparative Study.

Introduction: Influenza infection is associated with potential serious complications, increased hospitalization rates, and a higher risk of death. Materials and Methods: A retrospective comparative analysis of selected indicators of hospitalization from the University Hospital in Wroclaw, Poland, was carried out on patients with confirmed influenza infection in comparison to a control group randomly selected from among all other patients hospitalized on the respective wards during the 2018-2019 influenza season. Results: The mean laboratory testing costs for the entire hospital were 3.74-fold higher and the mean imaging test costs were 4.02-fold higher for patients with confirmed influenza than for the control group; the hospital expenses were additionally raised by the cost of antiviral therapy, which is striking when compared against the cost of a single flu vaccine. During the 2018-2019 influenza season, influenza infections among the hospital patients temporarily limited the healthcare service availability in the institution, which resulted in reduced admission rates to the departments related to internal medicine; the mean absence among the hospital staff totaled approximately 7 h per employee, despite 7.3% of the staff having been vaccinated against influenza at the hospital's expense. Conclusions: There were significant differences in the hospitalization indicators between the patients with confirmed influenza and the control group, which markedly increased the hospital care costs in this multi-specialty university hospital.

COVID-19 among Healthcare Workers in the University Clinical Hospital in Wroclaw, Poland.

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.

An analysis of the costs of treating aged patients in a large clinical hospital in Poland under the pressure of recent demographic trends.

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 Wroclaw, 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.

Health status, health behaviors, and the ability to perform everyday activities in Poles aged ≥65 years staying in their home environment.

BACKGROUND: The incidence of chronic diseases increases with age; about 73% of people who are aged ≥60 years suffer from at least 1 chronic disease, and among those older than 70 years, chronic diseases afflict more than >84% of the population. According to epidemiological data, at least 4 chronic disease types coexist in senior citizens, causing their disability. These are mainly cardiovascular diseases; motor system diseases; ophthalmological, auditory, neurological, and mental diseases; and mental impairment. They worsen or limit self-dependence in everyday activities. The process begins with complex activities and advances with age. At first, functional performance deficits are discreet; then, they may gradually lead to complete dependence on other people or institutions. OBJECTIVE: This study aimed to assess the relationship between diseases and health behaviors, as well as the everyday functioning of people aged ≥65 years staying in their home environment. METHODS: The research involved 504 elderly people. The inclusion criteria were age (≥65 years) and staying in one's own home environment. The direct interview technique was applied, as well as use of proprietary interview questionnaire and standardized tools used in geriatrics: Barthel scale, measuring performance in everyday activities, and the Instrumental Activities of Daily Living scale, assessing complex everyday activities. RESULTS: The most frequent disease among the responders was arterial hypertension (77.58%), followed by degenerative joint disease (62.10%), and circulatory failure (43.23%). Lower functional performance was associated with circulatory failure, cerebral stroke, atherosclerosis, Alzheimer's disease, diabetes, Parkinson's disease, degenerative joint disease, and bronchial asthma. Performance worsening significantly influenced the frequency of hospitalizations, with a mean score of 4.31 per person. Medical rehabilitation was practiced by 18.65% of the responders. CONCLUSION: Circulatory failure, cerebral stroke, atherosclerosis, bronchial asthma, diabetes, degenerative joint disease, Parkinson's disease, and Alzheimer's disease negatively affect functional performance in elderly people. Hospitalization rates increase with lowering independence in everyday functioning. Future research is needed with regard to the relationship between the practiced rehabilitation and independence in everyday functioning of the elderly.
