Effect of the PCV 10 vaccination on community-acquired pneumonia hospitalisations after four years of its introduction into the Polish National Immunisation Programme: Follow-up study

BACKGROUND

Vaccination against pneumococci is currently the most effective method of protection against pneumococcal infections. The aim of the study was to analyse changes in hospitalisations and in-hospital deaths due to pneumonia before (2009-2016) and after (2017-2020) the introduction of PCV 10 vaccinations in the National Immunisation Programme in Poland.

METHODS

Data on hospitalisations related to community acquired pneumonia (CAP) in the years 2009-2020 were obtained from the Nationwide General Hospital Morbidity Study. Analyses were made in the age groups: <2, 2-3, 4-5, 6-19, 20-59, 60+ years in 2009-2016 and 2017-2020.

RESULTS

Overall, there were 1,503,105 CAP-related hospitalisations in 2009-2020, 0.7% of which were caused by Streptococcus pneumoniae infections. Children <2 years of age were the most frequently hospitalised for CAP per 100,000 population, followed by patients aged 2-3, 4-5 and 60+ years. In the years 2009-2016, the percentage of CAP hospital admissions increased significantly, and after the year 2017, it decreased significantly in each of the age groups (p<0.001). In the years 2009-2016, a significant increase in hospitalisations for Streptococcus pneumoniae infections was observed in the age groups <2, 2-3 and 4-5 years (p<0.05). A significant reduction in hospitalisations was observed in the age groups <2, 20-59 and 60+ in 2017-2020 (p<0.05). In the years 2009-2020, there were 84,367 in-hospital deaths due to CAP, 423 (0.5%) of which due to Streptococcus pneumoniae, with patients mainly aged 60+.

CONCLUSIONS

Implementation of the PCV vaccination programme has effectively decreased the incidence of CAP hospitalisations, including children <2 years of age. The group that is most at risk of death are persons aged 60+. The results of our study can be useful in evaluating the vaccine efficacy and benefits, and they can be an essential part of public health policy. Effective prevention strategies for CAP should be implemented in different age groups.

Newborn Hospitalizations Before and During COVID-19 Pandemic in Poland: A Comparative Study Based on a National Hospital Registry

Objectives: There are limited data on the impact of the COVID-19 outbreak in Poland on newborn health. The aim of the study is to show recent information on hospitalizations of newborns in Poland in the pre-pandemic and COVID-19 pandemic era. Methods: A retrospective, population-based study was conducted using data from hospital discharge records of patients hospitalized in 2017-2021. Results: The data on which the study was based consisted of a substantial number of 104,450 hospitalization records. Annual hospitalization rate was estimated to be 50.3-51.9 per 1,000 in 2017-2019, 56 per 1,000 in 2020 and it rose to 77.7 per 1,000 in 2021. In comparison to the pre-pandemic period, in the COVID-19 era, we observed significantly more hospitalization cases of newborns affected by maternal renal and urinary tract diseases (p < 0.001), syndrome of infant of mother with gestational diabetes (p < 0.001), maternal complications of pregnancy (p < 0.001). In the COVID-19 era, the prevalence of COVID-19 among newborns was 4.5 cases per 1,000 newborn hospitalizations. Conclusion: The COVID-19 pandemic outbreak could significantly contribute to qualitative and quantitative changes in hospitalizations among newborns.

Hospitalizations of patients with sarcoidosis before and during the COVID-19 pandemic in Poland

INTRODUCTION

Sarcoidosis is a multisystemic granulomatous disease that mostly affects the lungs and lymphatic system. Due to its rarity and variable clinical course, analyses of factors related to sarcoidosis should be based on large databases and long observation periods.

OBJECTIVES

The aim of this study was to determine the characteristics of patients with sarcoidosis hospitalized in Poland over a long period (2016-2021).

PATIENTS AND METHODS

We conducted a retrospective study using hospital discharge records compiled by the National Institute of Public Health NIH - National Research Institute. We analyzed the records of patients with sarcoidosis from the entire Polish population at their first hospitalization.

RESULTS

We identified a total of 15 548 first-time hospitalizations for sarcoidosis. The mean annual disease incidence was 6.8 cases per 100 000. The mean (SD) age of the patients was 45.8 (13.6) years, and it was lower in men than in women (42.9 [12.5] vs 49.8 [14.2] years; P <0.001). There were significantly more hospitalizations among city dwellers (62.3% vs 37.3% for rural residents; P <0.001). At the beginning of the COVID‑19 pandemic in Poland there was a decrease in the number of hospitalizations for sarcoidosis, followed by an increase in the subsequent year. The all‑cause in‑hospital death rate was significantly higher during the COVID‑19 pandemic, as compared with the period before the pandemic (7.2 vs 2.3 per 1000; P <0.001).

CONCLUSIONS

Health care changes related to the outbreak of the COVID‑19 pandemic may have increased the health debt for inpatient sarcoidosis treatment. The occurrence of sarcoidosis in Poland may be related to demographic and territorial factors.

Time Trend Analysis of Comorbidities in Ankylosing Spondylitis: A Population-Based Study from 53,142 Hospitalizations in Poland

BACKGROUND

(1) Influence of comorbidities on life expectancy and treatment outcomes is one of the main concerns of modern rheumatology, due to their rising prevalence and increasing impact on mortality and disability. The main objective of our study was to analyze the time trends and shifts in the comorbidity profile and mortality over 10 years in the Polish population with ankylosing spondylitis (AS). (2) Data from 2011-2020 years were acquired from the General Hospital Morbidity Study in the National Institute of Public Health-National Institute of Hygiene (NIH-PIB) as ICD-10 codes. Based on ICD10 codes, we calculated the percentage shares for comorbidities, with the relative risk ratios and odds ratios. We analyzed the hospitalization rates and mortality from the overlapping conditions. Also, we analyzed age and sex related differences in the clinical manifestations of AS patients. (3) Results: From 53,142 hospitalizations of patients with AS, we found that the male population presented higher rates of cardiovascular (2.7% vs. 1.3% p < 0.001) and pulmonary conditions (1.2% vs. 0.8% p < 0.025). Inflammatory bowel diseases were more common in the female population than in males (2.3% vs. 1.7%, p < 0.001). In the years 2011-2020, we observed a decline in the number of hospitalized patients due to cardiovascular (p < 0.001) and respiratory system conditions (p < 0.001), yet the relative risk and odd ratios remained high. In the years 2011-2020, 4056 patients received biological treatment (7%). The number of initiated biological therapies correlated negatively with the number of reported hospitalizations due to ischemic heart diseases (IHD) (p < 0.031, r = -0.8). Furthermore, in the logistic regression model, we found strong collinearity between cardiovascular and pulmonary comorbidities (VIF = 14; tolerance = 0.1); also, the number of reported IHD's correlated positively with the number of pulmonary infections (p < 0.031, r = 0.7) (4).

CONCLUSIONS

Cardiopulmonary comorbidities are a main factor associated with increased mortality in patients with AS, especially in hospitalized patients. The mortality rates among patients with AS admitted to hospital due to other conditions other than movement disorders exceed the populational risk. The number of biologically treated patients correlated negatively with hospital admissions due to IHD.

Ukrainian migrants' and war refugees' admissions to hospital: evidence from the Polish Nationwide General Hospital Morbidity Study, 2014-2022

BACKGROUND

Considering the rapid influx of Ukrainian migrants and war refugees into Poland, the knowledge of their health condition is becoming increasingly important for health system policy and planning. The aim of the study was to assess war-related changes in the frequency and structure of hospitalizations among Ukrainian migrants and refugees in Poland.

METHODS

The study is based on the analysis of hospital admission records of Ukrainian patients, which were collected in the Nationwide General Hospital Morbidity Study from 01.01.2014 to 31.12.2022.

RESULTS

In the study period, 13,024 Ukrainians were hospitalized in Poland, 51.7% of whom had been admitted to hospital after February 24, 2022. After the war broke out, the average daily hospital admissions augmented from 2.1 to 21.6 person/day. A noticeable increase in the share of women (from 50% to 62%) and children (from 14% to 51%) was also observed. The average age of patients fell from 33.6 ± 0.2 years to 24.6 ± 0.3 years. The most frequently reported hospital events among the migrants until 23.02.2022 were injuries (S00-T98) - 26.1%, pregnancy, childbirth and the puerperium (O00-O99) - 18.4%, and factors influencing health status and contact with health services (Z00-Z99) - 8.4%. After the war started, the incidence of health problems among migrants and war refugees changed, with pregnancy, childbirth and the puerperium (O00-O99) being the most common - 14.9%, followed by abnormal clinical and lab findings (R00-R99) - 11.9%, and infectious and parasitic diseases (A00-B99) - 11.0%.

CONCLUSIONS

Our findings may support health policy planning and delivering adequate healthcare in refugee-hosting countries.

Trends in Hospitalization Duration for Rare Diseases: A Retrospective Analysis of Sarcoidosis, Still's Disease, and Systemic Sclerosis in Poland (2009-2018)

BACKGROUND A rare disease is a health condition that rarely occurs in the population. It is estimated that up to 400 million people around the world suffer from a rare disease. This retrospective study aimed to investigate factors associated with length of hospitalization in 78 626 patients with sarcoidosis, 3294 patients with adults-onset Still's disease, and 35 549 patients with systemic sclerosis between 2009 and 2018 using data from the National Institute of Public Health in Poland. MATERIAL AND METHODS In this population-based study, we analyzed hospital discharge records of first-time and subsequent hospitalizations. To perform the statistical analyses, R software was used. RESULTS The average length of hospitalization over the selected period in the diseases was 5.39 days for sarcoidosis, 6.22 days for scleroderma, and 7.44 days for Still's disease, and was shorter for each of the diseases analyzed compared with the length of hospitalization for second and subsequent stays. There were no substantial differences in length of hospitalization between males and females. The average length of hospitalization increased with each additional comorbidity. CONCLUSIONS The study showed that hospitalizations for selected rare diseases do not cause a significant burden on the healthcare system. The results also showed that advanced age and comorbidities are important factors determining the length of hospitalization. The average length of hospital stay for selected rare diseases in Poland is not longer than the European Union (EU) average, so it can be assumed that the process of inpatient treatment in Poland is optimal.

Epidemiological Characteristics of 101,471 Patients Hospitalized with Chronic Obstructive Pulmonary Disease (COPD) in Poland in 2019: Multimorbidity, Duration of Hospitalization, In-Hospital Mortality

Chronic obstructive pulmonary disease (COPD) is a common lung disease. There is a limited amount of nationwide data on COPD patients in Poland. This study aimed to characterize patients hospitalized with COPD in Poland in 2019 as well as to identify factors associated with the risk of in-hospital death and prolonged hospitalization among patients with COPD. This study is a retrospective database analysis. Data on patients hospitalized with COPD in Poland were obtained from the Nationwide General Hospital Morbidity Dataset. Data on all adults aged ≥40 years with a diagnosis of COPD from a physician (J44 code) were included in the analysis. Data were analyzed separately for patients hospitalized due to COPD (primary diagnosis) and patients with COPD as a comorbidity (secondary diagnosis). Completed medical records were available for 101,471 patients hospitalized with COPD (36.9% were females). Of those, 32% were hospitalized due to COPD. The mean age was 71.4 ± 9.7 years. The mean duration of hospitalization was 9.4 ± 11.4 days (median 7 days). Most of the COPD patients (89.3%) had at least one comorbidity. The in-hospital mortality rate was 6.8%. Older age, presence of cardiovascular diseases, and diseases of the genitourinary system (p < 0.05) were the most important factors associated with the risk of in-hospital death among patients hospitalized due to COPD.

Congenital toxoplasmosis among hospitalized infants in Poland in the years 2007-2021: study based on the national hospital registry

Congenital toxoplasmosis (CT) is a rare entity and it may pose a life-threatening risk for the newborns. The aim of the study was to evaluate the incidence and other selected factors of CT in Poland. Our study is a population-based study on CT patients in 2007-2021. The study was based on 1504 hospitalization records of first-time diagnosis of CT in newborns. In the study group, we observed 763 males (50.7%) and 741 females (49.3%). The mean and median age was 31 days and 10 days, respectively. Based on the hospital registry, the mean annual CT incidence was estimated to be 2.6 per 10,000 live births (95% CI 2.0-3.2 per 10,000 live births). The incidence of CT cases fluctuated over the years 2007-2021, with the highest incidence in 2010 and the lowest one in 2014. There were no statistically significant differences between the incidence of CT in relation to sex or place of residence. The periodic fluctuations in the number of cases of congenital toxoplasmosis indicates the need to develop effective prevention programs to effectively counteract the disease and its consequences.

A National Registry-Based Epidemiological Study to Evaluate 395 646 Patients Hospitalized Due to Eye Diseases in Poland in 2019

BACKGROUND The Nationwide General Hospital Morbidity Study Registry collects demographic, health, and medical data on patients hospitalized throughout Poland, and acts as a registry for epidemiological, public health, and hospital administrative studies. This epidemiological national registry-based study aimed to evaluate the characteristics of 395 646 patients hospitalized due to eye diseases in Poland in 2019. MATERIAL AND METHODS This study is a retrospective nationwide registry-based analysis. Data on all patients hospitalized due to eye diseases in 2019 were obtained from the Nationwide General Hospital Morbidity Study Registry. Demographic characteristics of patients hospitalized due to eye diseases as well as the hospitalization course were analyzed using descriptive epidemiology tools. RESULTS Disorders of the lens accounted for 68.6% of all hospital admissions, and disorders of the choroid and retina were the second most common (13.9%) cause of hospital admission due to eye diseases in 2019. Over three-quarters of hospital admissions (77.4%) lasted less than 24 h, and 86.8% were scheduled admissions. Most of the patients hospitalized due to eye diseases were females (59.9%) and over 70% lived in urban areas. There were regional differences in the hospital admissions rate per 100 000 inhabitants. According to the data presented in the registry, less than one-third of patients had comorbidities. CONCLUSIONS Hospital ophthalmological care in Poland is based mainly on planned hospitalizations lasting less than 24 h and related to ophthalmological surgery. Data on the comorbidity of ophthalmologic patients suggest that ophthalmologists do not pay enough attention to identifying and recording the patient's health status.

Hospitalization for dog bites in Poland between 2006-2020

INTRODUCTION AND OBJECTIVE

Owning a dog or spending time around a dog have many benefits, but also pose a risk of being bitten or attacked. Currently, publications on dog bites and related factors come from both high-income countries and low- and middle-income countries. So far, no attempt has been made to assess this phenomenon in Poland. The aim of this study was to determine the number of such events and evaluate hospital medical assistance provided to dog bite victims in Poland in the period of 15 years between 2006-2020.

MATERIAL AND METHODS

This cross-sectional study was based on the data from the Nationwide General Hospital Morbidity Study and cases with the code W54 (ICD-10) as the cause of hospitalization. As part of the analysis, victim demographical data, with an emphasis on city- and country-dwellers, as well as treatment variables were assessed.

RESULTS

Between 2006-2020, 4,145 cases of hospitalizations for dog bites were found, of which approx. 42% occurred in 2020 during the COVID-19 pandemic and lockdowns. Most of the victims were children aged 0-9, and this is especially common among boys living in the countryside. It was found that regardless of the place of residence, there was a systematic decrease in hospitalization of men as they were older. In women, however, the decrease in hospitalization concerned only the age groups 0-39. Among older women, the percentage of hospitalization increased, especially among rural women aged 60 and over.

CONCLUSIONS

Hospital discharge records report a small number of dog bites. These are only the tip of the iceberg. The problem has a multi-factorial nature and requires epidemiological monitoring and further research on correlates and determinants, as well as preventive measures.

Clinical Characteristics and Factors Associated with In-Hospital Mortality in 66 755 Patients Hospitalized Due to Diabetes in Poland, January to December 2019

Background

The global burden of diabetes mellitus is increasing, and diabetes poses a serious problem for the healthcare system. We aimed to characterize patients hospitalized due to diabetes in Poland in 2019 and identify factors associated with the risk of in-hospital death and prolonged hospitalization.

Material/Methods

Data on all patients hospitalized due to diabetes in Poland in 2019 were taken from hospital discharge records collected by the National Institute of Public Health, Warsaw, Poland. The presence of comorbidities, in-hospital mortality rate, and duration of hospitalization were analyzed separately for type 1 and type 2 diabetes.

Results

In 2019, a total of 28 617 patients were admitted to the hospital due to type 1 diabetes and 38 138 patients due to type 2 diabetes. The prevalence of comorbidities was 55.2% among patients with type 1 diabetes and 78.9% among those with type 2 diabetes. The in-hospital mortality rates were 2.1% and 3.3%, respectively. For emergency admissions, the in-hospital mortality rate was 4.0% and 4.5%, respectively. Over 30% of patients were hospitalized for more than 7 days. Older age and respiratory diseases were the most critical factors associated with higher risk of in-hospital death in patients with type 1 or type 2 diabetes (P<0.001). Male sex, age, and presence of at least 1 comorbidity were associated (P<0.001) with a higher risk of prolonged hospitalization.

Conclusions

Effective management of respiratory diseases in patients hospitalized due to diabetes, especially those admitted in an emergency, seems crucial to reduce the risk of in-hospital death.

Hospitalizations of Ukrainian Migrants and Refugees in Poland in the Time of the Russia-Ukraine Conflict

BACKGROUND

In the face of a sudden influx of several million migrants and war refugees from Ukraine to other European countries, knowledge about the health of Ukrainian citizens becomes increasingly important. The aim of the study is to identify the main health problems of hospitalized Ukrainian citizens residing in Poland in the period from 2014 to June 2022.

METHODS

This study is based on hospitalization data of Ukrainian patients in Poland taken from the Nationwide General Hospital Morbidity Study.

RESULTS

The study group covered 8591 hospitalization records. We observed two hospitalization peaks, one in patients aged 0-5 and the other one in those aged 20-35. After the official outbreak of the war, 2231 Ukrainian citizens were hospitalized in Poland. At this time, the most often reported principal reasons for the hospitalizations of adult women were diseases related to pregnancy, childbirth and the puerperium, whereas in groups of adult men diseases were related to injury, poisoning and certain other consequences of external causes, and in children and adolescents diseases were infectious and parasitic diseases.

CONCLUSIONS

Our findings may have implications for healthcare policies and service provision to newly arrived migrants and war refugees in target European countries.

Epidemiological Analysis of Diabetes-Related Hospitalization in Poland before and during the COVID-19 Pandemic, 2014-2020

Diabetes is one of the most common chronic diseases worldwide. The study aimed to present an epidemiological analysis of hospitalization related to diabetes mellitus in Poland between 2014 and 2020 as well as to analyze changes in diabetes-related hospital admissions before and during the COVID-19 pandemic. This study is a retrospective analysis of the national registry dataset of hospital discharge reports on diabetes-related hospitalizations in Poland between 2014 and 2020. The number of diabetes-related hospitalizations varied from 76,220 in 2016 to 45,159 in 2020. The hospitalization rate per 100,000 has decreased from 74.6 in 2019 to 53.0 in 2020 among patients with type 1 diabetes (percentage change: -28.9%). An even greater drop was observed among patients with type 2 diabetes: from 99.4 in 2019 to 61.6 in 2020 (percentage change: -38%). Both among patients with type 1 and type 2 diabetes, a decrease in hospitalization rate was higher among females than males (-31.6% vs. -26.7% and -40.9% vs. -35.2% respectively). When compared to 2019, in 2020, the in-hospital mortality rate increased by 66.7% (60.0% among males and 65.2% among females) among patients hospitalized with type 1 diabetes and by 48.5% (55.2% among females and 42.1% among males) among patients hospitalized with type 2 diabetes. Markable differences in hospitalization rate, duration of hospitalization, as well as in-hospital mortality rate by gender, were observed, which reveal health inequalities.

Analysis of diabetic patients hospitalizations in Poland by gender, age and place of residence

Background

There are few updated data on rates of hospital mortality of diabetic patients and length of their hospital stay on a country level. To determine such rates we provided analysis using claims data from a Nationwide General Hospital Morbidity Study carried out by the National Institute of Public Health - National Institute of Hygiene (NIPHNIH) in Warsaw from 2010 to 2018.

Objective

The aim of the study was to analyze the nine years changes of in-hospital morbidity and mortality in diabetic patients and length of hospital stay using a comparative approach by gender, age and place of residence.

Material and methods

The data on all patients from general hospitals in Poland treated because of diabetes were taken from a nationwide database, kept since 1979 by the Department for Monitoring and Analyses of Population Health of NIPH-NIH. This database contains information gathered under the Statistical Research Program of Public Statistics. Hospitalization rates were used to evaluate the 'hospitalized' incidence of diabetes (number of hospitalization cases due to diabetes per year by the analyzed unit of population). In-hospital mortality was calculated as the percentage of deceased patients out of all patients hospitalized due to diabetes.

Results

The number of cases and hospitalization rates of diabetic patients was rapidly declining by 18.8% for type 2 (E11) and 23.7% for type 1 (E10) diabetes. The downward tendency in the scope of hospitalization affected mainly older women and rural residents. Hospital mortality due to diabetes rose up dangerously to 3.77% exceeding the rates recorded eight years earlier.

Conclusions

The recent reduction in hospitalization rates of people with diabetes in Poland may be associated with an unexpected increase in hospital mortality.

The Prevalence of Acute Respiratory Distress Syndrome (ARDS) and Outcomes in Hospitalized Patients with COVID-19-A Study Based on Data from the Polish National Hospital Register

Acute respiratory distress syndrome (ARDS) is a serious complication of COVID-19. This study aimed to evaluate the prevalence of ARDS among patients hospitalized with COVID-19 in Poland as well as to characterize clinical outcomes in patients hospitalized with COVID-19-associated ARDS. This is a retrospective, secondary analysis of epidemiological data from 116,539 discharge reports on patients hospitalized with COVID-19 in Poland between March and December 2020. The overall prevalence of ARDS was 3.6%, respectively 2.9% among females, and 4.4% among males (p < 0.001). Of the 4237 patients hospitalized with COVID-19-associated ARDS, 3764 deaths were reported (88.8%). Participants aged 60 years and over had more than three times higher odds of COVID-19-associated ARDS. Men had higher odds of COVID-19-associated ARDS than women (OR = 1.55; 95% CI: 1.45–1.65; p < 0.001). Patients with COVID-19 and diabetes had higher odds of COVID-19-associated ARDS (OR = 1.16; 95% CI: 1.03–1.30; p = 0.01). Among patients with COVID-19-associated ARDS, older age, male sex (OR = 1.27; 95% CI: 1.03–1.56; p = 0.02), and presence of cardiovascular diseases (OR = 1.26; 95% CI: 1.00–1.59; p = 0.048) were significantly associated with the risk of in-hospital death. Among patients hospitalized with COVID-19 in Poland, the prevalence of ARDS was relatively low, but the in-hospital mortality rate in patients with COVID-19-associated ARDS was higher compared to other EU countries.

Congenital herpes simplex virus infection among hospitalized infants in Poland

INTRODUCTION AND OBJECTIVE

Congenital herpes simplex virus infection (cHSV) is a rare entity and may pose a life-threatening disease for the newborns. Due to the public health and clinical importance of cHSV infection in infants, the recent data on this disease in Poland should be investigated. The aim of the study was to evaluate the incidence and other factors related to cHSV.

MATERIAL AND METHODS

The study is retrospective, population-based that utilised the hospital discharge records of cHSV patients. Data were obtained from National Institute of Public Health NIH - National Research Institute in Warsaw, Poland, covering the period 2014-2019.

RESULTS

The study group consisted of 1,573 cHSV newborns (841 males and 732 females). Among this group, 70.1% were infants up to 90 days of age and 3.6% were neonates up to 28 days of age. The mean and median age was 98 days (95% CI: 94.5-101.8, SD 74) and 70 days (IQR: 53-104), respectively. Based on the hospital registry the overall average cHSV incidence over the study period was estimated to be 69 per 100,000 live births. The number of cHSV infection fluctuated over the years 2014-2019 with a significant decreasing trend from 2015-2019 (P<0.01). A significantly higher cHSV incidence was observed among patients from urban than rural areas of Poland (88 vs 40/100,000 live births; P<0.001).

CONCLUSIONS

CHSV incidence may be related to multifactorial conditions for the occurrence of this disease. Further studies on changes in the incidence of cHSV are needed.

Cost-effectiveness of public health interventions against human influenza pandemics in France: a methodological contribution from the FLURESP European Commission project

BACKGROUND

The FLURESP project is a public health project funded by the European Commission with the objective to design a methodological approach in order to compare the cost-effectiveness of existing public health measures against human influenza pandemics in four target countries: France, Italy, Poland and Romania. This article presents the results relevant to the French health system using a data set specifically collected for this purpose.

METHODS

Eighteen public health interventions against human influenza pandemics were selected. Additionally, two public-health criteria were considered: 'achieving mortality reduction ≥40%' and 'achieving morbidity reduction ≥30%'. Costs and effectiveness data sources include existing reports, publications and expert opinions. Cost distributions were taken into account using a uniform distribution, according to the French health system.

RESULTS

Using reduction of mortality as an effectiveness criterion, the most cost-effective options was 'implementation of new equipment of Extracorporeal membrane oxygenation (ECMO) equipment'. Targeting vaccination to health professionals appeared more cost-effective than vaccination programs targeting at risk populations. Concerning antiviral distribution programs, curative programs appeared more cost-effective than preventive programs. Using reduction of morbidity as effectiveness criterion, the most cost-effective option was 'implementation of new equipment ECMO'. Vaccination programs targeting the general population appeared more cost-effective than both vaccination programs of health professionals or at-risk populations. Curative antiviral programs appeared more cost-effective than preventive distribution programs, whatever the pandemic scenario.

CONCLUSION

Intervention strategies against human influenza pandemics impose a substantial economic burden, suggesting a need to develop public-health cost-effectiveness assessments across countries.

Adult-onset Still's disease in Poland - a nationwide population-based study

INTRODUCTION

Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disorder of unknown etiology, which affects young adults and is associated with multiple organ involvement and life-threatening complications. The aim of the study was to establish the incidence and prevalence of AOSD in Poland, and factors related to this disease among hospitalized patients.

MATERIAL AND METHODS

A retrospective, population-based study was conducted, using data from hospital discharge records compiled by the National Institute of Public Health in 2009-2018.

RESULTS

Based on hospitalization records and census data in a group of the 1,050 patients included in the study, women were predominant (60%) and patients' mean and median ages at hospitalization were 42 (95% CI: 40.8-42.8) and 38 years, respectively. The average annual incidence rate of AOSD during the 10-year period was established at the level of 0.32/100,000 (95% CI: 0.30-0.34), and the point prevalence at the end of 2018 was 2.7/100,000. The most common comorbidities were: cardiovascular diseases (14%), diseases of the musculoskeletal system and connective tissue (14%), endocrine, nutritional and metabolic diseases (9%).

CONCLUSIONS

AOSD is a rare disease Poland with gender and territorial differences in incidence ratek, and predominance of cardiovascular diseases among comorbidities. The presented data may be useful for comparisons of the Polish population with other geographical regions. Predominance of patients from urban regions and predominance of women may suggest environmental and personal factors in AOSD development; however, further research seems to be necessary.

Hospitalizations for COVID-19 in Poland: a study based on data from a national hospital register

INTRODUCTION COVID‑19 has been identified by the World Health Organization as a pandemic. Poland introduced extensive antiepidemic measures relatively early in order to slow down the spread of the disease. OBJECTIVES The study aims to present recent data on COVID‑19 hospitalizations during the first months of the disease outbreak in Poland. PATIENTS AND METHODS This is a retrospective, population‑based study conducted using hospital discharge records that included a diagnosis of COVID-19. Data were obtained from the National Institute of Public Health, where they had been originally collected for a Polish hospital morbidity study. They included 8840 hospitalization records from the period between February and September 2020. RESULTS Overall, there were 8252 records of patients hospitalized for COVID‑19 for the first time, which accounted for 93% of all hospitalizations. The study group consisted of 4161 men (50.4%) and 4091 women (49.6%). Significantly more patients from urban than rural areas were hospitalized (21.8 per 100 000 vs 20.5 per 100 000; P <0.02). In the period subject to analysis, 1073 in‑hospital deaths were observed (13% of all patients), 965 of which occurred during first‑time hospitalizations (11.7% of all patients). In the study group, patients who died during hospitalization compared with those who survived hospitalization were significantly older, more frequently lived in urban areas, and had more comorbidities. CONCLUSIONS The findings of our study, especially the differences between survivors and nonsurvivors with COVID-19, may be helpful in recognizing patients requiring special medical care and preventive measures during hospitalization.

Congenital cytomegalovirus infections in Poland - a national hospital register-based study

INTRODUCTION AND OBJECTIVE

Congenital cytomegalovirus (cCMV) infections are common worldwide. CCMV infected newborns are mostly asymptomatic at birth. However, cCMV remains the major infectious cause of congenital abnormalities in the developing foetus and newborns. The aim of the study was to provide recent data on cCMV in Poland.

MATERIAL AND METHODS

Aretrospective, population-based study was conducted using data from hospital discharge records of patients hospitalized from 2009-2018. CCMV incidence rates were estimated on the basis of data taken from a Polish hospital morbidity study, carried out by the National Institute of Public Health.

RESULTS

The study group consisted of 1,916 hospitalized patients with the first-time diagnosis of cCMV. Among them, 52% were patients up to 30 days of age. The median age was 28 days. The average annual incidence of cCMV was 48 per 100,000 live births (95% CI 23.5-73.4). A significantly higher cCMV incidence rate was observed in patients from more urban than rural regions of Poland (55 per 100,000 vs 39 per 100,000; P<0.001). In the study period, 9 hospital deaths (0.5 % of all patients) were reported. The coexistence of nervous system diseases was observed in 26% of cases and hearing loss in 6% of cases.

CONCLUSIONS

The significantly more cCMV cases were observed in patients from more urban than rural regions of Poland may suggest the presence of territorial factors related to the cCMV incidence in Poland. The relatively high percentage of newborns with hearing loss or neurologic diseases may require activities aimed at reducing the cCMV incidence. The epidemiological data presented may be useful for comparisons with other geographical regions.

Asbestosis hospitalizations in Poland (2006-2016): results from the National Hospital Discharge Registry

INTRODUCTION AND OBJECTIVE

Occupational asbestos exposure is one of the major public health issues. Although asbestos use in Poland has decreased, asbestosis continues to remain an important health concern in the area of occupational medicine. The aim of the study is to perform a descriptive analysis of hospitalization cases in patients suffering from asbestosis in Poland.

MATERIAL AND METHODS

The authors used hospital discharge records to conduct a retrospective, population-based study. To estimate the asbestosis hospitalization rate, data from the Nationwide General Hospital Morbidity Study conducted by the National Institute of Public Health were used. Events were defined as in-patient hospital discharges during 2006-2016. 1,101 hospitalization records of 764 patients were included in the study.

RESULTS

In the study group of first-time hospitalized patients, the mean and median ages were 68.1 and 69 years, respectively; CI: 67.3-68.9; SD: 11.1, min-max:16-99 years. In this group, significant gender differences were observed (560 males vs. 204 female; P<0.001). No statistical differences were observed regarding the place of residence. During the observation period, 61 in-hospital deaths were reported (8% of all patients), 40 of whom (5.2 % of all patients) took place during the first-time hospitalizations. Asbestosis hospitalizations were mainly clustered in the south-western region, whereas the highest hospitalization rates were clustered in several areas of Poland.

CONCLUSIONS

The authors believe this study to be the first evaluation of asbestosis in Poland made on the basis of the hospital morbidity database. The data presented may be helpful in comparative studies on the epidemiology of asbestosis across European countries.

Variations in experience of social support and physical health among adult residents of Poland in urban versus rural areas

Background

A study reveals – against to common beliefs –less support between rural area residents in comparison to town-dwellers and significantly higher support for healthy, not for poor health research participants.

Objectives

The aim of our paper was comparing support from spouse/partner, relatives, friends and strangers among people with good and ill physical health. A next purpose was to find differences of social support and experience of social undermining in urban and rural residential settings.

Material and methods

The study “Epidemiology of Mental Disorders and Access to Mental Health Care, EZOP – Poland” was carried out on random sample of 24 000 of Poland residents and a 50,4% response rate, 10 081 computerassisted personal interviews. Of those respondents, 4 000 constituted a sub-sample asked to complete the social networks and support section of the questionnaire. Data were analyzed by age, gender, residential setting and marital status for statistically significant differences in the percentage of functional and structural social support being reported, using the chi-squared test with a significance level of 0.05 used to reject the null hypothesis (H0 = lack of relationship between variables).

Results

A majority of respondents maintain that in difficult life situations, family and a close network of friends and acquaintances make it possible to openly discuss problems and obtain help. However, respondents who rate their health as “poor” or “very poor” significantly less often than healthy individuals experience support coming from their relatives, friends, or strangers. In comparison to urban areas, the extent of social support in rural areas is significantly limited. The rural setting offers less support and even less opportunities for interaction with relatives, friends, acquaintances and strangers. Negative social factors– low levels of trust, isolation from friends and family, lack of a social life, lack of a helpful neighborhood – are conditions significantly more often found in the countryside than in urban areas.

Conclusions

Results obtained from the EZOP study shows that amount of social support received is higher in urban areas and among those who enjoy better physical health.

Nationwide General Hospital Morbidity Study as a source of data about Polish population health

The objective of this article is description of the important source of data on hospitalised morbidity collected in Poland within the frameworks of public statistics, and also underlying the significance of the quality of data collected at the hospital level for the purpose of the practical application of them. The Nationwide General Hospital Morbidity Study has been conducted by the Department of Population Health Monitoring and Analysis of the NIPH-NIH for more than 40 years within the frameworks of the Programme of Statistical Surveys of Official Statistics. Since the year 2000, it has had a complete character, collecting individual data for all cases of hospitalisation in Poland within the scope compliant with the MZ/Szp-11 form, among others, sex, age, place of residence of a patient, data on hospital, information about the course of treatment (length of stay in hospital, principal diagnosis and comorbidity, applied medical procedures, the mode of admission and discharge). The collected data are anonymous. In the recent years, annually, more than 8 million of the cases of hospitalisation have been documented. Almost all obliged hospitals (96%) participate in the study. Some weak point is the completeness of submitted data, in particular, regarding information about the external causes of injuries and poisonings (in the year 2017, 27% of the required data were missing). Interestingly, a high level of missing data is generated by a comparatively small number of hospitals. Significant differences are observed in the quality of data depending on the voivodship of hospital location. The collected data render it possible to, among others, determine the frequency of hospitalisations due to particular causes taking under consideration the localisation of a hospital, and also the sex, age and the place of residence of patients, the analysis of the duration of hospital stay or in-hospital fatality. The aggregated results are reported to international databases (WHO, OECD, Eurostat), and support the administrative authorities of various levels. They are also a basis for numerous published scientific papers. The most important results of routine analyses are presented of the web page of the Study (http://www.statystyka1.medstat.waw.pl/).

Sarcoidosis among hospitalized patients in Poland: a study based on a national hospital registry

INTRODUCTION

Sarcoidosis is a systemic granulomatous disease mainly affecting the lungs, although granulomas can also involve any other organ.

OBJECTIVES

We sought to describe patients during their first hospitalization for sarcoidosis in Poland from 2008 to 2015. To our knowledge, this is the first evaluation of the disease in Poland based on a hospital morbidity database.

PATIENTS AND METHODS

We conducted a retrospective, population‑based study, using hospital discharge records compiled by the National Institute of Public Health in the years 2008 to 2015.

RESULTS

Among the 23 097 patients included in the study, men were predominant (54.7%). The mean and median ages at hospitalization were 44.7 years (95% CI, 44.5-44.9) and 42 years, respectively. Most patients (65%) resided in urban areas. The average annual incidence rate of sarcoidosis was 7.5 per 100 000 (95% CI, 7.1-7.9). The lungs were the most commonly affected organ (57.9%), while the remaining cases included sarcoidosis of lymph nodes and no lung involvement (18%), the skin (1.4%), and other or unspecified sites (22.7%). Skin sarcoidosis occurred significantly more frequently in women, while sarcoidosis of the lungs with coexisting sarcoidosis of lymph nodes was significantly more prevalent in men. Seasonal variability in sarcoidosis incidence was observed.

CONCLUSIONS

Sex and age may have a significant impact on the occurrence of sarcoidosis in Poland. Changes in seasonality may suggest the role of environmental factors. These data on sarcoidosis in Poland may be helpful in comparative analyses with other European countries.

Takayasu's arteritis: a rare disease in Poland

INTRODUCTION

Takayasu's arteritis (TA) is a rare and potentially life-threatening granulomatous large-vessel vasculitis that involves mostly in the aorta and its proximal branches, and occurs most commonly in young females. This study measures the incidence and prevalence of TA, and assesses the gender distribution and territorial differences in the occurrences of this disease in Poland over a five-year period. To the best of our knowledge, this is the first evaluation of this rare disease in Poland based on a hospital morbidity database.

MATERIAL AND METHODS

Analyses were performed with population-based administrative data obtained from a national hospital morbidity study carried out between January 2011 - December 2015 by the Polish National Institute of Public Health. Yearly incidence rates and prevalence of TA were calculated using the number of TA patients and corresponding census data for the overall Polish population.

RESULTS

Data included 660 hospitalization records. The final study sample comprised 177 patients: 154 female (87%) and 23 male (13%) with first-time hospitalization for TA. The mean age was 45.4years (95% CI: 42.9-47.8; SD 16.8; range 4-81 years), median 47. The incidence rate of TA was estimated at 0.92 per million per year (95% CI: 0.68-1.16). Five-year TA prevalence was estimated to be 4,6 per million. Incidence rates of TA did not vary significantly between more urban and more rural regions.

CONCLUSIONS

The incidence of TA in Poland was similar or lower to data reported by other European countries. The study provides epidemiological data on TA in Poland that may be useful while comparing it with other geographical regions.

Paget disease of bone among hospitalized patients in Poland

INTRODUCTION

Paget's disease (PDB) is a focal disorder of bone remodeling that occurs commonly in older people with decreasing prevalence reported in European countries. This disease is most often asymptomatic, but it can cause a variety of medical complications resulting in considerable morbidity and reduced quality of life. There is little information regarding the epidemiology of PDB in Poland. To the best of the authors' knowledge, this is the first large epidemiological analysis of this disease in Poland.

OBJECTIVE

The aim of this study was to analyze factors that may be related to the PDB epidemiology among hospitalized patients in Poland.

MATERIAL AND METHODS

The analysis was conducted on the basis of population-based administrative data, taken from a Polish hospital morbidity study carried out by the National Institute of Public Health between January 2008 - December 2014.

RESULTS

Analyzed data covered 662 hospitalization records. The final study sample comprised 94 (41.8%) male and 131 (58.2%) female patients with first-time hospitalizations for PDB, with a significant predominance of females (P<0.02), and the predominance of patients living in urban (73%) than in rural areas (27%), P<0.001. The average age of the sample was 56.8 years (CI: 54.3-59.3; SD 18.8; range 1-93 years). The number of PDB cases hospitalized in Poland significantly decreased during the analyzed period of time.

CONCLUSIONS

PDB is a rare disease with decreasing trends observed among hospitalized patients in Poland. The study results may suggest the existence of environmental risk factors for the development of PDB.

Behçet disease: a rare systemic vasculitis in Poland

INTRODUCTION    Behçet disease (BD) is an immune‑mediated small‑vessel systemic vasculitis, which is rarely seen in Poland. OBJECTIVES    The aim of this study was to evaluate the incidence and prevalence of BD, as well as to assess the sex and geographical distribution of BD in Poland during a 7‑year follow-up. To our knowledge, this is the first evaluation of this rare disease in Poland, based on a hospital morbidity database. PATIENTS AND METHODS    We analyzed population‑based administrative data obtained from a national hospital morbidity study conducted between January 2008 and December 2014 by the National Institute of Public Health in Poland. The annual incidence rates and point prevalence of BD were calculated using the number of patients with BD and corresponding census data for the overall Polish population.  RESULTS    Data included 316 hospitalization records. The final study sample comprised 130 patients (54 men [42%] and 76 women [58%]) with first‑time hospitalizations for BD. The mean (SD) age was 41.6 (18.7) years (95% confidence interval [CI], 38.3-44.8; range, 5-85 years). The incidence rate of BD was estimated at 0.5 per million persons per year (95% CI, 0.35-0.61). The point prevalence at the end of 2014 was 3.4 per million persons. The incidence rate of BD did not vary significantly between more urban and more rural regions, and BD was observed more often in women than in men. CONCLUSIONS    BD is endemic in Eastern and Central Asian countries, but is also seen in Poland. However, its incidence and prevalence rates are lower in Poland than in other European countries.

Trends in Hospitalization of Children with Bacterial Pneumonia in Poland

AIM

The aim of the study was to evaluate the hospitalization trends in children aged 0-6 suffering from bacterial pneumonia in the years 2007-2011 in Poland.

METHODS

The data pertained to the hospitalized patients diagnosed with the diseases registered as J13-J15 according to ICD-10.

RESULTS

In the years 2007-2011, the hospitalization rate increased from 16.3/10,000 to 44.1/10,000 for boys and from 13.8/10,000 to 33.0/10,000 for girls. The most frequently hospitalized children were between 1 and 2 years of age (90.6/10,000 for boys and 58.0/10,000 for girls in 2011). The average length of stay (LOS) of the investigated children fell from 10.1 days in 2007 to 8.2 days in 2011. The longest stays were recorded for the youngest children, under 2 years of age (from almost 11 days in 2007 to around 9 days in 2011).

CONCLUSION

Bacterial pneumonia is a serious problem of public health and especially babies are at high risk of this disease. Given the effects of vaccinations against Streptococcus pneumoniae conducted all over the world and to a limited extend in Poland as well, further steps towards vaccinating children against pneumococci should be taken in Poland.

Incidence and prevalence of Systemic Sclerosis (SSc) in Poland - differences between rural and urban regions

[b] Abstract Introduction.[/b] Systemic sclerosis (SSc) is a rare and potentially severe connective tissue disease, characterized by skin fibrosis and involvement of internal organs. Because of its rarity and heterogeneous clinical presentation, reliable epidemiological studies on SSc have been particularly difficult to carry out. [b]Objectives[/b]. The purpose of this study was to present SSc epidemiology among hospitalized patients in Poland.

MATERIALS AND METHOD

The analysis was based on population-based administrative data, taken from a Polish hospital morbidity study carried out by the National Institute of Public Health between January 2008 - December 2012. [b]Results[/b]. Analyzed data covered 9,049 hospitalization records. The final sample comprised 3,653 patients with first-time hospitalizations for SSc. The average age of the sample was 53 years (SD 16.2; range 0-91 years); 84% of patients were female and 16% male. Based on hospitalization registers, the average SSc incidence was estimated to be 1.9/100,000 per year and peak age of incidence was 55 years. The point prevalence was estimated to be 9.4/100,000 at the end of 2012. SSc was more common in females, with F:M ratio ranging from 6.2:1-4.6:1 depending on the year. Analysis of hospitalization trends revealed that overall numbers of SSc hospitalizations increased, while first-time hospitalizations decreased between 2008-2012. Clusters of higher incidence were observed in more rural regions vs. urban regions. [b]Conclusion[/b]. Estimated incidence of SSc in Poland was comparable to reported incidence in other European countries. Analysis of demographic factors and reports of clusters of higher incidence may suggest the existence of environmental risk factors for the development of SSc. These observations may require further research.

Hospitalization of injured immigrants in Poland - Utilization of in-patient services

INTRODUCTION AND OBJECTIVE

In 2008-2010, the number of foreigners hospitalized due to injuries in Poland ranged from approximately 5-21 thousand. The aim of this study was to analyse the utilization of in-patient services by injured immigrants in 2008-2010, including mode of admission (i.e. referral), mode of discharge, average length of patient stay, seasonality and spatial distribution of hospital admissions.

MATERIAL AND METHODS

Analysis was conducted on the basis of data from the General Hospital Morbidity Study. All cases of hospitalization due to injuries were covered by the analysis, and a group of foreigners was compared to the general population.

RESULTS

The percentage of immigrants admitted by acute admission through self-referral increased to 80.9% in 2010. The great majority (79.4%) were discharged to in-patient care. The immigrants' stay in the hospital was approximately twice as short than that of an average patient with injury. Immigrants and the rest of the patients were admitted to hospitals in different seasonal rhythm. The great majority of foreigners were treated in hospitals located in two (out of 16) provinces.

CONCLUSIONS

This study supports the need for understanding the immigrant experience when accessing health care, as well as the need for further research and contribution of public health.

Hospitalization of injured immigrants in Poland - Demographic profile and diagnosis

INTRODUCTION AND OBJECTIVE

More and more immigrants gradually come to Poland. Little is known, however, about their health situation or their injuries. The objective of this study was to analyse the cases of hospitalization of immigrants due to injuries in 2008-2010, including the number and demographic characteristics of the patients, as well as the nature of injury according to ICD-10 (S00-T98).

MATERIAL AND METHODS

The analysis was conducted on the basis of data from the General Hospital Morbidity Study. All the cases of hospitalization due to injuries were covered by the analysis, and a group of foreigners was compared to the general population.

RESULTS

The number of foreigners hospitalized due to injuries ranged from 4.6-21.2 thousand in the subsequent years. The share of hospitalization due to injuries equalled 8.2-11.9% of all foreigners' hospital stay. The majority were males, but the proportion of females gradually increased up to 36.7% in 2010. The average age of the hospitalized gradually decreased to the age of 35.2 in 2010. The structure of the nature of injury was different from that of the general population. Prevailing types of injuries were minor injuries of wrist, hand, ankle and foot. Open wounds of the head were also common.

CONCLUSIONS

Results of the analysis indicate the most important tendencies related to immigrants' injuries. Further research, as well as monitoring the foreigners' health status is necessary. Taking preventive measures is essential among the most vulnerable group - male immigrants aged 15-19.

Indirect effects of a 7 year PCV7/PCV13 mass vaccination program in children on the incidence of pneumonia among adults: a comparative study based on two Polish cities

BACKGROUND AND OBJECTIVES

In 2006 the city of Kielce, Poland, introduced a mandatory PCV7 (replaced by PCV13 in 2011) vaccination program against S. pneumoanie for all children under 2 years old. At that time, the neighboring city of Ostrowiec Świętokrzyski had no such large-scale vaccination program in place. This created an opportunity to observe the results of the vaccination by comparing the incidence of pneumonia in these two cities. The aim of this study was to analyze how the incidence of pneumonia among adults was indirectly affected by the PCV7/PCV13 vaccination program in children during the 7 year follow-up period.

METHODS

We performed a retrospective study. PCV7/PCV13 vaccinations were delivered according to a 2 + 1 schedule. The vaccination rate in the analyzed period amounted to almost 99%. The following age groups were analyzed: 30-49, 50-64 and 65+. The Cochran-Armitage test was used to investigate the significance of the observed trend in pneumonia morbidity. The significance of deviations from a linear trend was also tested. In addition, the importance of the trend (in the case of deviations from linearity) was confirmed with the use of the Mantel test.

RESULTS

In the 65+ age group there was a decrease of 66.5% in the incidence of diagnosed pneumonia (p < 0.0001). This was followed by smaller, but statistically significant, declines in the other age groups: 30.75% in the 30-49 age group (p = 0.001) and 56.8% in the 50-64 age group (p < 0.0001). This decreasing trend continued for seven consecutive years of observation. In addition, we demonstrated a statistically significant higher rate of pneumonia in all age groups in the City of Ostrowiec Świętokrzyski.

CONCLUSIONS

The results clearly indicate that the indirect effectiveness of the PCV7/PCV13 vaccine program, performed according to the 2 + 1 schedule and applied in Kielce, Poland, is statistically significant.

The burden of Herpes Zoster and its complications in Poland in according to the age

BACKGROUND

Incidence of shingles in different regions of the world ranged from 300 to 500/100,000 persons, and in the population older than 80 years of age reaches more than 1000/100,000. In the age group 50+ the incidence is enough high to be a serious medical and economic burden. Lack of details about the incidence and frequency of complications in Polish population let us too made an attempt to assess the scale of the problem, among others to the purpose of the evaluation of the legitimacy of implementing vaccination in the 50+ population.

METHODS

First, based on coming data from the Świętokrzyskie Province Division of the National Health Fund we judged the incidence of shingles in this province in 2013 in individual ancient groups and depending on detailed diagnoses and with the division into the basic health, clinic and hospital care. Second, based on gathered data through NIZP-PZH, we judged hospital morbidity connected with shingles in Poland in 2008-2012 years, in individual ancient groups.

RESULTS

Extrapolating the data from the Świętokrzyskie province we assess the incidence of shingles on average 338.8/100,000. She is tallest in the age group 50+ (614.3/100,000) and in this group also the most complications are being observed. Hospital morbidity in entire Poland showed in 2008-2012 years the frequency on average 4.93-5.42/100,000, in the group of 0-19 years; 0.10-1.50/100,000, in the group of 20-49 years; 4.9-5.42/100,000 and in the 50+ group--9.99-13.37/100,000.

CONCLUSIONS

(1) Shingles, especially in the 50+ age group, constitutes a serious health problem in Poland, being a cause of numerous advices in basic health care and at clinics in Poland, as well of numerous hospitalizations and dangerous complications. (2) It seems, that active immunization against shingles, especially of 50+ persons, would be a favourable solution from the individual, as well as public perspective.

Fall related hospital admissions among seniors in Poland in 2010

BACKGROUND

Falls among elderly people causing hospitalization are considered one of the most important public health problems. Our objective was to analyse fall related hospital admissions among seniors (> or = 65 years old) in Poland in 2010. The analyses were conducted with regard to gender, place of residence and age. Additionally, the health consequences of falls among elderly people were studied. Injuries and other consequences of external causes, were expressed in the form of three-character ICD-10 codes representing the underlying disease (S00-T98).

METHODS

Data on hospital admissions resulting from falls among seniors were obtained from the database held at the Department - Centre for Monitoring and Analyses of Population Health Status and Health Care System by the National Institute of Public Health - National Institute of Hygiene.

RESULTS

Analysis has shown that the hospitalization ratio due to falls is much higher for women than for men. On average, 1 024 per 100 000 women are hospitalized due to a fall, while the number for men is 649. For every analysed age group women are at a higher risk of hospitalization due to a fall than men. In 2010 nearly 70% of hospital admissions of elderly people due to a fall were caused by a fall on the same level as a result of tripping or slipping (31 712 hospitalizations). No differences in relation to gender were observed. Risk of hospitalization due to a fall increases with age. For people over 80 years of age it is 2.5 times higher than for people in the 65-69 age group (1 459 and 570 per 100 000 respectively). It was observed that the length of hospital stay increases with age. There were no significant differences between the number of hospitalizations depending on the place of residence. The analysis showed that differences in the length of stay for women and men are statistically significant. However, there was no statistically significant difference between the lengths of stay depending on a place of residence. Almost one-third of hospitalizations (31.4%) resulted from femur fracture (14 356 hospitalizations). Women are more likely to suffer from a femur fracture.

CONCLUSIONS

A comparison of results of research conducted, among other countries, in the United States, The Netherlands, and Denmark, as well as Polish demographic prognosis, has shown that an increase of fall related hospital admissions among senior citizens is to be expected in Poland in oncoming years.

[Hospitalization of people with eating disorders in Polish general and psychiatric hospitals in years 2003-2007]

OBJECTIVE

Analysis of dynamics of eating disorders hospitalization based on data from Polish general and psychiatric hospitals in 2003-2007.

METHOD

Data was derived from databases of Department-Centre for Monitoring and Analyses of Population Health in National Institute of Public Health-National Institute of Hygiene in Warsaw and Department of Health Care Organization in Institute of Psychiatry and Neurology in Warsaw. Gender, age and patients' place of residence were analyzed in the study. Prevalence rate was used to evaluate of eating disorders hospitalization.

RESULTS

People suffering from eating disorders were hospitalized in general as well as psychiatric hospitals. Females were hospitalized more often than males. Prevalence rate decreased in both kinds of hospitals during analyzed period: about 5% in psychiatric hospitals and about 14% in general hospitals. Among eating disorders, anorexia nervosa was diagnosed most often. Girls suffering from anorexia were most often 14-16 years old. Mean time of hospitalization of people with eating disorders in psychiatric hospitals was twice longer than in general hospitals.

CONCLUSIONS

Despite the increase in eating disorders prevalence rates in young people in the world, the systematic decrease of hospitalization of patients with eating disorders in Poland was observed. The decrease of patients' age was also noticed. Females were hospitalized much more often than males, what was observed in previous study.

[Perception of environmental health risks related to living in the vinicity of communal waste incineration plant--part II]

OBJECTIVE

The analysis of the environmental risk perception by residents living in the vicinity of the Solid Communal Waste Utilisation Plant (ZUSOK) in Warsaw. The study was to reveal the factors related to perception the incinerator as a cause of frequent illnesses in the families and to intention of changing the place of residence because of the plant's neighbourhood.

MATERIAL AND METHODS

questionnaire survey of 501 respondents, who have been living in the radius of 3km from the incinerator since at least 2 years prior to its activation. The multiple logistic regression method was applied to indentify demographic factors and opinions concerning the environment and incinerator activity associated with the aforementioned declarations.

RESULTS

44% of respondents with frequent illnesses in the family claimed that their problems may be caused by incinerator activity. This declaration is significantly negatively related to: older age (45 years or more) combined with period of residence in the district longer than 40 years (OR=0.4) and positively related to: believes that health problems in community would increase in the course of incinerator activity (OR=7.3), to continuous/very frequent smelling of unpleasant odour in the air (OR=2.8) and considering the odour as a serious disturbance caused by incinerator' (OR=2.8). About 28% of respondents would change the place of residence because of the incinerator's vicinity. The frequency of this declaration increases with: shorter distance between residence and plant (OR=2.0), negative attitude towards the idea of incinerator construction (OR=2.9), opinion that ZUSOK emits to environment large quantities of harmful substances (OR=2.5), health consequences will increase in the course of incinerator activity (OR=3.1), continuous/very frequent smelling smoke in the breathing air (OR=2.6), complaining about the transport of ashes from the incinerator (OR=2.3). People older than 45 years and living in the district more then 40 years significantly less frequent declare possibility of move (OR=0.5).

CONCLUSION

Risk perception reduction necessitates taking some educational actions for inhabitants and verifying their complaints about quality of air.

[Healthy life years (HLY) comprehensive indicator of health situation--recommended by European Union]

This article presents Healthy Life Years (HLY) indicator of functional health status, its application in the field of public health research and monitoring, method of calculation, idea of its construction and relation of HLY to other health status indicators e.g. life expectancy, quality adjusted life years. Current data on HLY in the EU member states are also presented. HLY indicator is one of structural indicators, recommended by European Council to deliver information on the progress of implementation of the Lisbon Strategy resolutions, which main principle is development of knowledge-based economy characterised by growth, social cohesion and respect for environment. HLY shifts the focus from quantity of years of life to its quality, full-productivity health of the population, thus conveying information not only on health status but also referring to the fields--other than medicine or social sciences--such as: finances, economy, politics, development.

[Perception of environmental health risks related to living in the vicinity of communal waste incineration plant]

OBJECTIVE

an evaluation of the environmental risk perception by residents living in proximity to the Solid Communal Waste Utilisation Plant (ZUSOK) in Warsaw.

MATERIAL AND METHODS

a questionnaire survey of 501 respondents was conducted. All subjects have been living within a radius of 3 km from the incinerator since at least 1998. The relations between declared opinions and demographic status of the respondents (gender, age, education level, distance from dwelling place to ZUSOK, and period of residence) were examined, and the resulting associations were expressed as odds ratios (OR).

RESULTS

only 32% of subjects knew about incinerator construction project, and 28% of them heard about the protests which had taken place there. It was found that just 12% of respondents felt sufficiently informed about the environmental impacts of ZUSOK activities. Their anxieties concerned the considerable infiltration of harmful substances to the environment (according to 60% of subjects, significantly more frequently women and people declaring lack of sufficient information about ZUSOK) and increase of health problems in the local community by the long-term incinerator activity (by 71% of respondents, significantly more frequently by respondents with lack of sufficient information). Emission of smoke/dust and unpleasant odour were declared as the most disturbing aspects of the neighbourhood by about 50% of subjects. The respondents declaring lack of sufficient information about incinerator activity complained more frequently about its disturbances. Continuous or very frequent smelling of air contamination was found a factor significantly increasing probability of negative assessment of ZUSOK neighbourhood.

CONCLUSION

it is necessary to take some information and education actions aimed at inhabitants of the vicinity of the plants potentially increasing environmental health risk.

[Are rheumatic complaints significantly related to functional ability after 60 year of age?]

INTRODUCTION

Medical care focused on functional abilities gives the elderly with arthritis a possibility of living an independent, active life and participating in social activities, and thus it is seen as the policy of equal chances.

OBJECTIVES

The aim of the current paper is the assessment of the Polish adult population mobility level, the changes coming with age, and the statistical significance of relations between rheumatic complaints and a decrease in functional abilities in the elderly.

PATIENTS AND METHODS

The results of the all-Poland epidemiological research are presented. The survey conducted on a random sample of adult Poles with arthritis took place in 2002. A total of 4017 respondents answered questionnaires prepared by professional investigators.

RESULTS

A significant deterioration of functional abilities can be noticed after the age of 40 and it becomes even more severe after 60. A negative assessment of musculoskeletal functions was declared by 70% of the investigated arthritis elderly people. Respondents did not take into account cognitive dissonance when comparing themselves with a peer group. That is why every second patient considered himself mobile enough for his/her age. A low functional assessment relates significantly to the awareness of having arthritis. Higher education increases chances of maintaining functional abilities up to older age. Exercises "for health" are more popular among older men than older women.

CONCLUSIONS

Effective preventing the elderly from physical unfitness should be the duty of individuals, medical care and social policy. Popularizing information on the benefits of physical exercises, awareness of the disease, and shifting the time of intervention to the middle age generation can help achieve this aim.

[Seasonal variation of hospital morbidity from asthma in Poland]

The aim of the paper was to describe and compare the seasonal hospital admissions among different subgroups of patients due to bronchial asthma with a special focus on demographic characteristic. Data were collected during the calendar year 2003. Data were gathered for 32,933 patients from 522 hospitals across Poland with confirmed diagnosis of bronchial asthma or status asthmaticus. We noticed a distinct seasonal patterns in the number of hospitalizations due to asthma. Most cases clustered in the beginning and the end of the calendar year. Beside these hospitalization peaks, we observed a less pronounced increase of hospital admissions in spring and through summer months. It was most distinctly pronounced in children. It was also shown that gender of patients did not affect seasonal variability in our study. Emergency admissions to hospitals were less frequent in summer months, whereas elective admissions presented no such distinct pattern. The data revealed differences in seasonality in asthma hospital admissions in various age groups.

[Short-term effect of air pollution with sulphur dioxide, black smoke and nitrogen dioxide on mortality of urban Polish population]

The paper presents results of analysis of short-term effect of atmospheric air pollution with sulphur dioxide (SO2), suspended particles (BS) and nitrogen dioxide (NO2) for daily number of death from all causes (without external), from diseases of cardiovascular and respiratory diseases and from malignant neoplasms in four Polish cities Kraków, Lódź, Poznań and Wrocław. Analysis was carried out using modern methods of statistical modeling--generalized additive models. Potential confounding factors (long-term changes of mortality, day of week, meteorological conditions, national and summer holidays and periods of influenza epidemics) were taken into account during model building process. Results for every city and from meta-analysis are presented. Statistically significant increase of mortality from all causes was associated with increase in all investigated air pollutants.

[The application of DPS/HIS system in demographic study of the Polish-German cross border region]

Demographic situation in Polish and German cross border regions was compared in this study. The data from 17 Polish powiats, including 2 cities with powiat status: Gorzów Wielkopolski i Zielona Góra, and from 7 German powiats (Kreis), including 2 cities with powiat status (Kreisfreie Stadt): Cottbus and Frankfurt on Odra were analysed. The data concerning demographic structure of population, live births, perinatal and infant mortality were stored and analysed using Data Presentation System (DPS 2.0). In Polish powiats higher percentage of children and adolescents, and lower percentage of population in age 65 years and more was observed than in German Kreis. Both in Poland and in Germany the cities with powiat status differ from other powiats of their country by low percentage of the young (up to 14 years old in Germany and less than 24 in Poland). In Polish powiats more children are born in relation to both the total population and number of women in reproductive age (15-44 years). The decrease in number of live births observed recently in both countries is stronger in Poland. The perinatal mortality in Polish zone systematically decreased, reaching the level close to that of German zone. Despite the infant mortality in Polish zone is decreasing, it's still almost twice higher than in German zone.
