Epidemiology of Rheumatoid Arthritis (RA) in rural and urban areas of Poland - 2008-2012.

OBJECTIVE: The aim of this study is to investigate the morbidity rate due to Rheumatoid Arthritis (RA) in the Polish population during 2008-2012, calculated per 1,000 inhabitants, and taking into account the differences between provincess, area of residence (urban or rural) and gender. MATERIALS AND METHOD: From the NFZ IT systems, PESEL number information was obtained for all 17 types of services contracted in 2008-2012, for patients whose main diagnosis in the report was the ICD-10 disease code: M05.X - seropositive rheumatoid arthritis, or M06.X - other rheumatoid arthritis. The number of patients, gender and age were calculated based on the PESEL number provided in the statistical reports of the patient with the analysed ICD-10 diagnosis. Urban and rural cases were compared using commune zip codes. The basis for classifying the patient as a member of an urban or rural population was the Zip Code of the declared place of residence. Urban and rural areas are classified based on administrative criteria provided by the Central Statistical Office: the National Official Register of Territorial Division of the Country (TERYT). RESULTS: During the studied period the number of RA patients increased from 173,844-230,892. In urban areas, the most patients were recorded in the Slaskie Province, the least in Lubuskie Province. Patients from rural areas were approx. 1/3(rd) of the total population of patients in Poland. In rural areas, the most patients were recorded in the Mazowieckie Province, the least in Lubuskie Province. The morbidity rate in cities was 5.08 in 2008 and increased to 8.14 in 2012 in rural areas, respectively, it was 3.74 and increased to 3.98. Regardless of the place of residence the women fell ill 3.5 times more frequently. The lowest morbidity rate, both in rural and urban areas, was recorded in the Lubuskie Province, the largest in Swietokrzyskie Province. The the most probable explanation of the highest morbidity rate in the latter province is a worse access to a rheumatologist: in this province there is the lowest number of inhabitants per one employed rheumatologist. CONCLUSION: In Poland, the number of RA sufferers is increasing, which is probably a result of increasing life expectancy. In Poland, also exists a differences in morbidity between urban and rural inhabitants. Differences may also derive from undiagnosed cases of the disease.

Epidemiology of asthma in Poland in urban and rural areas, based on provided health care services.

INTRODUCTION: Asthma is a serious health and social problem, also in Poland. The epidemiological data indicate that the problem of asthma concerns approximately 4 million people in Poland, whereas almost approximately 70% of them have no diagnosis and are not aware of their illness, and on the other hand in 39% of persons who declared the diagnosis of asthma in a survey the diagnosis was negatively verified (overdiagnosis of asthma). So far, no detailed comparative studies for asthma incidence rate in urban and rural areas were conducted in Poland. The aim of the study was to analyze patients with asthma in Poland in the years 2008-2012, with regard to province and type of commune (rural/urban). MATERIAL AND METHODS: The study used data from National Health Fund (NFZ) - reported by health care providers regarding the patients diagnosed with asthma. Using structured query language (SQL) a set of patients was selected and created, for whom at the same time ICD-10 code: J45.X-bronchial asthma was reported. In order to estimate the number of patients with asthma we used the PESEL social security number as a unique identifier of the patient. Code of the patient's commune of residence in conjunction with the Central Statistical Office data formed the basis for the division of municipalities into urban and rural areas. The analysis of asthma incidence trends in Poland was performed on the basis of health services provided to patients. The analysis was performed by using the Statistica 10 software using a negative binomial regression model. RESULTS: In 2009 a significant increase in the number of patients with asthma was observed compared with the previous year, whereas after 2009 the number of patients diagnosed with asthma remained relatively constant. A significant increase of predominance of women among asthma patients in recent years can be noticed: from 107% in 2008 to almost 115% in 2012 (F:M ratio). Regardless of the analyzed year and the diagnosis the incidence rate remained constant: approximately 55-57% for urban areas and about 43-45% in rural areas. CONCLUSIONS: The average prevalence rate for rural areas is significantly lower than for urban areas. The use of adjusted incidence rate leads to the conclusion that the number of sufferers in urban areas is higher (about 10%) of the number of sufferers in the rural areas. The results of the analysis are consistent with information from previous studies in Poland and in the world.

Changes in the morbidity and costs of systemic lupus erythematosus in Poland in the years 2008-2012.

OBJECTIVES: The goal of the article is to present the changes in morbidity and costs of systemic lupus erythematosus (SLE) in Poland in the 2008-2012 period, depending on the province of residence of the patients based on data reported to the public payer - the National Health Fund. MATERIAL AND METHODS: Based on the ICD-10 code and the patient's personal identity number, the number of patients and medical costs (cost of hospitalization, pharmaceutical, medical procedures, dialysis and specialist consultations) were calculated by province (voivodeship) and urban or rural residence. RESULTS: Annually on average in the assessed period in Poland approximately 20 000 patients were diagnosed with SLE. The studied group was dominated by women (they were 5.2 times more numerous). The morbidity rate was 52.183 patients per 100 thousand inhabitants. Most patients were in the age range of 48-56 years. Average annual expenses for this group of patients over the examined period were USD 16,327 million. Two times more was expended on patients inhabiting cities, approximately 4 times more on women. Calculated per patient, the average cost of therapy was USD 810.63. CONCLUSIONS: The population of SLE patients in Poland is highly stable. The results of analysis indicate 1.64 times more frequent occurrence in urban areas, which may be connected with availability of doctors. The SLE treatment costs in Poland are much lower than in other countries, which is related mainly to the fact that therapy with biological drugs is not financed.

Comparison of indicators of the use of insulin and oral diabetes medication in a Polish population of patients in urban and rural areas in the years 2008, 2011 and 2012.

INTRODUCTION: Diabetes is one of the 10 most important chronic diseases in the world. According to the data of the International Diabetes Federation, in Poland 9% of the population between the ages of 20-79 suffer from diabetes. OBJECTIVE: The aim of this study was to investigate the differences in the prevalence of diabetes in urban and rural areas in Poland, and the preparation of a model describing the phenomenon. MATERIALS AND METHOD: Differences between urban and rural areas were studied for the occurrence of patients treated with diabetes per 100,000 inhabitants, the number of patients, structure of treatment per the used products, and the costs of reimbursement of treatment products between 2008-2012. Urban and rural cases were compared using zip codes. The basis for classifying a patient as being an inhabitant of an urban or rural area was an urban zip code of the declared place of residence. RESULTS: Differences were observed both between various areas of Poland, as well as depending on whether the declared place of residence of the patient was urban or rural. Differences between urban and rural areas within the studied period have increased. The difference in the prevalence of diabetes among the inhabitants of Podlaskie, Slaskie or Swietokrzyskie provinces is striking. CONCLUSION: Differences between urban and rural areas which depend on morbidity and detection of patients in the earlier phase of illness, the structures of medical technologies used in the treatment process, the number of purchased pharmaceuticals, enable better monitoring of effectiveness and quality of politics on prevention and treatment of chronic diseases. It is important for the creation of a health policy to devise a system of indicators, which will enable a decrease in the existing differences between regions, and between the urban and rural areas within the provinces.
