Costs of plasmocytic myeloma therapy in the drug programme at a Regional Oncology Centre in Poland.

INTRODUCTION: The rapidly growing market for drugs, including oncology and haemato-oncology drugs, is generating enormous financial expenditure for healthcare systems. In Poland, access to high-cost treatments is possible mainly within drug programmes, funded by public healthcare systems. The path of proceeding adopted in Polish regulations is similar to the solutions adopted in other countries. OBJECTIVE: The aim of this study was to demonstrate the actual costs incurred by the treatment entity in the process of treating patients under the drug programme at the Regional Oncology Centre in Olsztyn, north-east Poland. MATERIAL AND METHODS: The oncology drug programme B.54 'Treatment of patients with refractory or malignant plasmocytic myeloma' implemented at the Regional Oncology Centre in Poland between 2018-2021, was selected for the analysis. The choice of the B.54 programme was based on the small population of patients meeting the inclusion criteria for this programme, and the large number of diagnostic procedures stipulated in the drug programme description. On average, 25 patients were treated per year. The financial analysis used the financial categories related to hospital billing information. The costs were presented based on the purchasing power parity of money in 2021, i.e. 1 USD-inter is equivalent to 1.837 PLN. RESULTS: The flat rate form of financing medical services does not cover the actual costs of treatment. Providing patients with necessary medical services without their full coverage by the public payer, burdens the budget of the centre and may lead to indebtedness of the treatment entity. CONCLUSIONS: Without an increase in the valuation of benefits under drug programmes, corresponding to the actual costs of treatment, the expected increase in access to innovative therapies will be difficult to accomplish.

Epidemiology of multiple myeloma in Poland in the years 2008-2017.

Introduction: Multiple myeloma is the third most common blood cancer in Europe and accounts for approx. 10-15% of these cancers. The objective of this study was to determine the incidence, prevalence, mortality and survival in multiple myeloma (ICD code: C90.0) patients in Poland in the years 2008-2017. Material and methods: The analysis used the data on healthcare services provided to patients with multiple myeloma defined with the ICD-10 (International Statistical Classification of Diseases and Related Health Problems) code C90.0 and reported by healthcare entities to the National Health Fund (NFZ). Results: In 2009, the C90.0 incidence per 100,000 inhabitants was 6.4, while in 2017 it was 8.3. The prevalence in the same period increased by 76%, from 13.6/100,000 to 23.9/100,000. The mortality to prevalence ratio gradually decreased from 78% in 2008 to 22.8% in 2017. The 1-year, 3-year and 5-year survival rates in patients with this diagnosis made in the years 2009 and 2013 were 70.5%, 51.5% and 40.2% versus 78.4%, 60.3% and 48.3%, respectively. Conclusions: The incidence and prevalence of multiple myeloma and survival rates in Poland were continuously increasing in the studied period. These trends may result from the aging of Polish society, better recognisability of multiple myeloma and/or improved access to increasingly more effective therapies in Poland. The impact of these factors on the epidemiology of multiple myeloma requires further studies.

Overall survival of patients with EGFR mutation-positive non-small-cell lung cancer treated with erlotinib, gefitinib or afatinib under drug programmes in Poland - real-world data.

INTRODUCTION: The aim of the study was to estimate the overall survival of patients with EGFR mutation-positive non-small-cell lung cancer treated with erlotinib, gefitinib or afatinib. MATERIAL AND METHODS: Real-world patients who received afatinib, erlotinib or gefitinib between 1 July 2012 and 30 October 2017 were analysed in five subgroups. RESULTS: Among 267 patients treated with afatinib financed as the first line of treatment, 76 (28.46%) deaths occurred. Median observation time was 12.8 months (95% CI: 11.2-13.9). Median OS was 22.8 months (95% CI: 19.2-27.1). Among 83 patients who received erlotinib financed exclusively as the second line of treatment the number of deaths was 74 (89.16%). Median observation time was 64.3 months (95% CI: 60.4-64.6). Median OS was 16 months (95% CI: 13.2-22.9). Among 622 patients who received erlotinib financed both as first and second line treatment, there were 400 (64.3%) deaths. Median observation time was 33.3 months (95% CI: 31.2-37.6). Median OS was 17.8 months (95% CI: 16.4-19.7). Among 137 patients who received gefitinib financed only as the first line of treatment, there were 128 (93.4%) deaths. Median observation time was 58.3 months (95% CI: 49.4-62.5). Median OS was 16 months (95% CI: 13.8-19.7). Among 348 patients who received gefitinib financed both as the first and second line of treatment the number of deaths was 208 (59.8%). Median observation time was 23.7 months (95% CI: 20.7-28.7). Median OS was 15.5 months (95% CI: 12.9-17.5). CONCLUSIONS: Our real-world data regarding OS confirm the benefits found in clinical trials from the use of afatinib, erlotinib or gefitinib. However, the lower overall survival rate of Polish patients compared to similar studies from other research centres suggests the need for deeper investigation of this issue.

Overall Survival in Patients with Hepatocellular Carcinoma Treated with Sorafenib: A Polish Experience.

BACKGROUND The mortality caused by hepatocellular carcinoma is expected to rise in the upcoming decade. Sorafenib has become the preferred systemic treatment option in patients with unresectable HCC. This study aimed to present the median overall survival (OS) in a group of patients with advanced HCC, treated with sorafenib in Poland between 2011 and 2019. MATERIAL AND METHODS The analyzed group of patients was qualified for treatment with sorafenib, financed by the National Health Fund, based on the guidelines of the Polish Drug Program. Kaplan-Meier method was used to plot the OS curves, and the log-rank test was used for testing. Multivariate assessment of factors (sex and age) related to the time to death of the patient was done using Cox regression. RESULTS Of the 2072 treated patients, 75% were men (1556) and 25% were women (516). The minimum age of patients in the trial group was 18 years and the maximum age was 90 years. Among the 1556 analyzed cases in males, 27.44% (427) did not end with death (by the date of completing the analysis). The percentage of one-year survival for this population was 58.16%, and the 2-, 3-, and 5-year survival rates were 34.45%, 21.81%, and 9.72%, respectively. The percentage of censored cases in the 516 females was 25.78% (133). The 1-2-, 3-, and 5-year survival for this population was 59.30%, 36.27%, 22.47%, and 11.34%, respectively. Statistical tests did not reveal a significant difference in the curve profiles by sex. There were no associations between OS and age. CONCLUSIONS Systemic treatment with sorafenib in accordance with the presented criteria allows for very good results, comparable to the results of selected groups of patients presented by other authors.

The problem of Lyme borreliosis infections in urban and rural residents in Poland, based on National Health Fund data.

INTRODUCTION AND OBJECTIVE: Some fragmentary studies show that the incidence of Lyme borreliosis in Poland is increasing. It has been generally accepted that the most affected are forestry workers and farmers. The aim of the study is to compare the incidence of borreliosis in urban and rural residents in 2008-2016. MATERIAL AND METHODS: Databases on Lyme borreliosis from the National Health Fund and Central Statistical Office in Poland were analyzed. For each patient, ambulatory or discharged from every hospital, the diagnosis was compulsorily reported as encoded following the International Classification of Diseases. RESULTS: A steadily increasing number of patients with borreliosis in Poland was found, which doubled in 2008 - 2016. The incidence was similar in urban and rural residents. In all the provinces in Poland, an increase in incidence of borreliosis was observed, although there were big differences between them. The highest frequency of borreliosis was in Podlasie and Warmia-Masuria provinces. The lowest incidence of borreliosis was noticed in Wielkopolska province. In the most provinces the increase in the incidence of borreliosis was steady, except Warmia-Masuria, where it was very low in 2008, and soaring since 2011. The number of cases per year between 2008 - 2016 increased in both in males and females. CONCLUSIONS: The results suggest the need for higher awareness of the risk of Lyme borreliosis in urban residents, because the incidence of Lyme borreliosis is growing independently of the place of residence. Prompt measures to prevent tick bites and appropriate education are urgently needed.

Schizophrenic patients with type 2 diabetes: An 8-year population-based observational study.

This paper presents a realistic evaluation of the prevalence of type 2 diabetes mellitus (T2DM) among Polish schizophrenic patients who have sought treatment through the Polish National Health Fund in the years 2010-2017. Data from the National Health Fund database was used and T2DM and schizophrenia groups were defined according to International Classification of Diseases (ICD-10) codes. Demographic data were collected from the web page of Statistics Poland (GUS). The annual prevalence of T2DM and schizophrenia was estimated, and the age groups were categorised into eight sets. The incidence of schizophrenia in T2DM patients in the years 2010-2017 was measured, including relative risk and 95% confidence interval (95% CI). The incidence of T2DM has been assessed in various subtypes of schizophrenia. In the eight years of follow-up study, 1,481,642 patients with schizophrenia were included, of which 185,205 were also diagnosed with T2DM. This accounted for 12.50% of all patients with schizophrenia. The trend of comorbid schizophrenia (F20) and T2DM (E11) in the general population of patients with schizophrenia, who sought treatment through the National Health Fund, was relatively stable in the years 2010-2017. The relative risk of T2DM in those with schizophrenia was 8.33 (95% CI 8.23-8.43) in 2017. Taking actions to enable the detection of diabetes in patients with concomitant schizophrenia is well-grounded, although these actions should be gender-dependent. There is also a need to take adequate actions to improve the efficiency of diabetological care among patients with schizophrenia.

Relationship between age and in-hospital mortality during 15,345,025 non-surgical hospitalizations.

INTRODUCTION: Mortality, whether in or out of hospital, increases with age. However, studies evaluating in-hospital mortality in large populations did not distinguish between surgical and non-surgical causes of death, either in young or in elderly patients. The aim of the study was to assess in-hospital non-surgical mortality in a large group of patients, with a special focus on the elderly. MATERIAL AND METHODS: Data from the database of the Polish National Health Fund (NHF) regarding hospitalizations of adult (≥ 18 years) patients not related to surgical procedures in the years 2009-2013 were used to assess in-hospital mortality. RESULTS: 15,345,025 hospitalizations were assessed. The mean in-hospital non-surgery-related mortality rate was 3.96 ±0.17%, and increased from 3.79% to 4.2% between 2009 and 2013. The mean odds ratio for in-hospital death increased with the age of patients, reaching a 229-fold higher rate in the ≥ 95 years age group as compared to the 18-24 age group. The highest mean mortality was associated with respiratory diseases (6.91 ±0.20%), followed by heart and vascular diseases, nervous system diseases, as well as combined gastrointestinal tract, liver, biliary tract, pancreas and spleen diseases (5.65 ±0.27%, 5.46 ±0.05% and 4.01 ±0.13%, respectively). CONCLUSIONS: The in-hospital non-surgery-related mortality rate was approximately 4%. It significantly increased with age and, regardless of age, was highest in patients suffering from respiratory diseases.

Predictors of In-Hospital Mortality in Surgical Wards: A Multivariable Retrospective Cohort Analysis of 2,800,069 Hospitalizations.

BACKGROUND: Identifying prognostic factors that are predictive of in-hospital mortality for patients in surgical units may help in identifying high-risk patients and developing an approach to reduce mortality. This study analyzed mortality predictors based on outcomes obtained from a national database of adult patients. MATERIALS AND METHODS: This retrospective study design collected data obtained from the National Health Fund in Poland comprised of 2,800,069 hospitalizations of adult patients in surgical wards during one calendar year. Predictors of mortality which were analyzed included: the patient's gender and age, diagnosis-related group category assigned to the hospitalization, length of the hospitalization, hospital type, admission type, and day of admission. RESULTS: The overall mortality rate was 0.8%, and the highest rate was seen in trauma admissions (24.5%). There was an exponential growth in mortality with respect to the patient's age, and male gender was associated with a higher risk of death. Compared to elective admissions, the mortality was 6.9-fold and 15.69-fold greater for urgent and emergency admissions (p < 0.0001), respectively. Weekend or bank holiday admissions were associated with a higher risk of death than working day admissions. The "weekend" effect appears to begin on Friday. The highest mortality was observed in less than 1 day emergency cases and with a hospital stay longer than 61 days in any type of admission. CONCLUSION: Age, male gender, emergency admission, and admission on the weekend or a bank holiday are factors associated with greater mortality in surgical units.

Trends in psoriatic arthritis epidemiology in Poland.

Psoriatic arthritis (PsA) is a heterogeneous inflammatory arthritis, usually seronegative and associated with psoriasis (Ps). The prevalence and incidence of psoriatic arthritis show strong ethnic and geographic variations. The aim of the study was to assess the epidemiological trends in psoriatic arthritis in Poland. The National Health Fund (NHF) database for the period 2008-2018 was analyzed. PsA was defined as ICD-10 codes L40.5, M07, M07.0, M07.1, M07.2 and M07.3, while psoriasis as ICD-10 codes L40 and L40.X (L40.0 to L40.9). A steady increase in the number of PsA patients (from 16,790 to 32,644) and in PsA recorded prevalence (from 38.47 per 100,000 in 2008 to 73.11 per 100,000 in 2018) was observed between 2008 and 2018. The PsA/Ps ratio increased to a similar extent (from 8.3 to 17.5%). The percentage of PsA patients receiving rehabilitation services remained constant throughout the observation period (mean: 17.35%; range 16.7-18.9%). The study showed a steady and continuous increase in PsA recorded prevalence. A simultaneous increase in the PsA/Ps ratio suggests that the main reason for the observed trend is greater disease detection .

Predictors of in-hospital mortality in nonsurgical departments: a multivariable regression analysis of 2 855 029 hospitalizations.

INTRODUCTION: In­hospital mortality is a relevant outcome of hospital admissions. OBJECTIVES: This study aimed to identify predictors independently associated with in­hospital mortality in nonsurgical departments. PATIENTS AND METHODS: In 2014, the Polish National Health Fund database provided data on 2 855 029 hospitalizations of adults, which were not related with surgical procedures. Patients' age and sex, diagnosis­related group category assigned to the hospitalization, length of stay, types of hospital and admission, and day of the week and month of admission were analyzed as mortality predictors. RESULTS: The mean (SD) in­hospital mortality rate was 4.1% (0.01%). Odds ratios for in­hospital death increased with patients' age. The female sex was associated with lower odds ratios of death than the male sex. Among the diagnosis­related groups assigned to hospitalizations, the highest mortality was found in patients with vascular diseases (11.95%). Considering the length of stay, the lowest mortality occurred during 5- to 7­day (2.63%). Compared with teaching hospitals, the odds ratio of death was 1.31­fold higher for regional hospitals, 1.35­fold higher for private hospitals, and 1.48­fold higher for district and city hospitals; 92% of all in­hospital deaths occurred after urgent and emergency admissions. Hospital admissions at weekends or on other nonworking days (public holidays) were significant predictors of in­hospital mortality. Differences in mortality rates were found between particular months, but no seasonal relationship was established. CONCLUSIONS: Age, male sex, emergency admission, admission at the weekend or on another nonworking day (during public holidays), and hospitalization in a district, city, private, or regional hospital (compared with a university hospital) were factors associated with higher mortality in nonsurgical departments.

Prevalence of axial spondyloarthritis in Poland.

The prevalence of axial spondyloarthritis (axSpA) in the published data varies significantly. Two types of axSpA can be distinguished depending upon the presence of abnormalities consistent with sacroiliitis on plain radiography: ankylosing spondylitis (AS) and nonradiographic axial SpA (nr-axSpA). The aim of this study is to perform a retrospective analysis of axSpA prevalence in Poland in the years 2008-2017. The National Health Fund (NHF) database for the period 2008-2017 was analysed. Data of all patients with the ICD-10 codes M46 (M46.1, M46.8, M46.9) or M45 (further named other inflammatory spondylopathies-OIS and AS, respectively) as the main or co-existing diagnosis were extracted and analysed. The AS prevalence was stable during the period under examination amounting to approximately 0.083%, while the OIS prevalence increased from 0.036 to 0.059%. For both men and women, the AS prevalence increased with age, reaching a maximum around the age of 70; however, in men, a marked increase in prevalence was observed earlier as compared to women (20-24 vs. 40-44 years, respectively). The OIS prevalence also increased with age; however, the maximum was reached earlier as in case of AS. Moreover, a sharp increase in OIS prevalence occurred earlier than in AS (15-19 years) with no difference between sexes. In Poland, approximately 0.1% of the population suffers from AS-the prevalence remained stable over the last decade. The prevalence of OIS increased markedly over the studied period which presumably reflects an increasing prevalence of nr-axSpA as the effect of the introduction of ASAS classification criteria for axSpA.

Analysis of the survival of patients receiving systemic treatment for melanoma of the skin: a retrospective population study with patients treated in Poland in 2011-2015.

INTRODUCTION: In Poland, it is uniquely possible to assess real effects of the introduction of new oncological therapies on the overall survival in patients as such therapies are funded by one payer only - the National Health Fund (NHF). Data collected by the NHF make it possible to analyse the survival of all patients who were diagnosed with melanoma. AIM: The paper presents findings of a retrospective analysis of the efficacy of systemic treatment in patients with malignant melanoma of the skin in Poland with regard to the overall survival. MATERIAL AND METHODS: The analysis of the overall survival was performed with the Kaplan-Meier method in the population receiving systemic treatment. Three groups of patients were analysed. Group 1 included all patients who had started systemic treatment between 1 March 2011 and 1 March 2015: 1,258 patients. The median overall survival was 8.4 months. Group 2 included 444 patients who had started systemic treatment between 1 March 2011 and 28 February 2013. The median overall survival was 6.6 months in this group. Group 3 included 814 patients who had started systemic treatment between 1 March 2013 and 1 March 2015 and included 546 patients who were also treated in drug programmes with ipilimumab and vemurafenib (approx. 67%). The median overall survival was 9.4 months. RESULTS: A difference in the overall survival between group 3 and 2 was statistically significant (p < 0.05). CONCLUSIONS: The introduction of vemurafenib and ipilimumab into systemic treatment in Poland using public funds had a significant effect on the prolongation of the overall survival in patients with malignant melanoma of the skin.

Eating Disorders in Males: An 8-Year Population-Based Observational Study.

The objective of the study was the realistic evaluation of the prevalence of eating disorders (ED) among Polish men who sought treatment through the National Health Fund (NFZ) in the years 2010-2017. According to ICD-10, four types of ED were analyzed: anorexia nervosa-AN (F50.0), atypical anorexia nervosa (F50.1), bulimia nervosa-BN (F50.2), and atypical bulimia nervosa (F50.3). The NFZ database was used. The ED groups were defined according to ICD-10 codes. Demographic data were collected from the web page of Statistics Poland (GUS). The annual prevalence of EDs was estimated, and the age groups were categorized into nine groups. For the incidence of EDs in male patients in the years 2010-2017, relative risk (RR) with 95% confidence interval (95% CI) was calculated. The frequency trend of AN in males remains relatively stable. AN occurred mainly in young men (between 11 and 30 years). It was noted that AN affected approximately 100 men in each year of observation, while atypical anorexia nervosa affected about 40 men. In 2017, the RR for EDs in young males was 0.041 (95% CI [0.033, 0.051]). Bulimia was relatively rare (about 35 males each year). The incidence of EDs in males is a relatively constant phenomenon. The real number of male patients with EDs may be higher. The current conceptualizations of ED pathology should be modified and better adapted to men. Clinical guidelines for specialists working with males with EDs should be developed.

Syphilis in Poland is on the rise and underreported.

INTRODUCTION: Despite the availability of diagnostic tests and effective treatment, there has been a problem with vigilance and reporting of that infectious disease in many countries including Poland. AIM: To compare the incidence of syphilis in Poland in years 2010-2016 according to the mandatory epidemiological surveillance system with the data of the National Health Fund (NHF). MATERIAL AND METHODS: Data of the NHF in Poland were collected. The total number of patients with syphilis (all forms) was estimated on the basis of their unique identifying numbers (PESEL). RESULTS: The steady increase in the incidence of syphilis in Poland throughout 2010-2016 was found, apart from the congenital form of the disease, which decreased since 2010. The higher prevalence of syphilis was noted in men. The number of hospitalized patients remained constant. According to the data of the NHF, the number of cases of syphilis in Poland was twofold higher as compared to the statistics of the mandatory epidemiological surveillance system (National Institute of Public Health - National Institute of Hygiene, NIPH-NIH), which was the basis of reports published up to date. CONCLUSIONS: Our work shows that there is a remarkable underreporting of syphilis in the mandatory epidemiological surveillance system in Poland, involving also hospitalized patients. The use of the data of NHF in the surveillance of syphilis in Poland is proposed.

Real-World Evidence of Patient Outcome Following Treatment of Advanced Gastrointestinal Stromal Tumor (GIST) with Imatinib, Sunitinib, and Sorafenib in Publicly Funded Health Care in Poland.

BACKGROUND This study aimed to undertake an analysis of ten years of real-world evidence (RWE) on overall survival (OS) following treatment of advanced gastrointestinal stromal tumor (GIST) with imatinib, sunitinib, and sorafenib using data from the Polish National Health Fund. MATERIAL AND METHODS Data from the Polish National Health Fund, the sole Polish public payer, identified 1,641 patients with advanced GIST who were treated with imatinib (n=1047), sunitinib (n=457), and sorafenib (n=137). The differences in overall survival (OS) were analyzed. RESULTS For patients with advanced GIST, the median follow-up time for patients treated with imatinib was 71 months (95% CI, 64.8-79.2), the median OS was 56.9 months (95% CI, 50.4-61.2), with survival at 12 months (89.5%), 24 months (77.9%), 36 months (66.9%), and 60 months (48.4%). The median follow-up time for patients treated with sunitinib was 41.4 months (95% CI, 34.6-49.3), the median OS was 22.8 months (95% CI, 19.2-26.8), with survival at 12 months (68.2%), 24 months (47.1%), and 36 months (31%). The median follow-up time for patients treated with sorafenib was 17.4 months (95% CI, 14.6-22.9), the median OS was 16.9 months (95% CI, 13.7-24.3), with survival at 12 months (61.9%), at 24 months (36.2%), and at 36 months (16.8%). CONCLUSIONS Real-world data collected in a ten-year period confirmed the effectiveness of the use of imatinib, sunitinib, or sorafenib for the treatment of advanced GIST and was comparable with the findings from clinical trials.

Severe Depressive Episode with Psychotic Symptoms and Type 2 Diabetes: A 2010-2017 Longitudinal Study.

BACKGROUND There have been few studies published on the prevalence of severe depressive episode in people with type 2 diabetes (T2DM) or its role in adherence to dietary recommendations. We examined the Polish National Health Fund (NFZ) database estimates of all medical visits from 2010 to 2017 to determine the trend and the epidemiology of severe depressive episode in T2DM. MATERIAL AND METHODS The NFZ database was used. We defined the T2DM group diagnosed with both T2DM and severe depressive episode according to the ICD-10 codes. The annual prevalence of severe depressive episode was estimated according to the T2DM diagnosis status, and the age groups were stratified into 8 groups. RESULTS Relative risk for depression (regardless of severity of symptoms) in T2DM is 1.347 [95%CI: 1.342-1.353]. The frequency trend of severe depressive episode with or without psychotic symptoms remains relatively stable. In the case of mild and moderate depressive episode, a downward trend was noted, but they are still the most frequent mood disorders diagnosed. Patients with T2DM aged 20 to 40, for whom the peak of coexistence of these illnesses was noted, are the group particularly vulnerable to depression. Depression also remains on a relatively high but stable level for patients over 60 years of age. CONCLUSIONS The coexistence of depressive episodes in T2DM is a key challenge for medicine and public health. Measures aimed at early identification of patients with T2DM prone to depression need to be taken. Creating multidisciplinary care teams in diabetes management is also necessary.

Epidemiology and direct costs of atopic dermatitis in Poland based on the National Health Fund register (2008-2017).

INTRODUCTION: Epidemiological data indicate significant differences in atopic dermatitis (AD) prevalence between countries. AIM: The purpose of this study is to (i) analyse the recorded prevalence of atopic dermatitis (diagnoses of AD reported to the Polish National Health Fund (NHF)) and to (ii) estimate direct costs of medical care for AD incurred by the NHF. MATERIAL AND METHODS: The analysis was based on data reported to the database of the public payer (NHF). The prevalence rates were calculated using the NHF data and population estimates were obtained from the Central Statistical Office of Poland (GUS). RESULTS: In 2017, the annual prevalence rate of AD in the Polish population was 32.5 per 10,000 inhabitants (34.7/10,000 for women and 30.1/10,000 for men). The highest prevalence was observed in the youngest age groups (300/10,000 in children up to 4 years of age and 141/10,000 in 5-9-year-olds). The prevalence rate decreased with age and AD was the least prevalent in patients over 85 years of age (4/10,000). In 2008-2017, NHF expenditure on AD treatment varied between PLN 19.9 million (EUR 5.6 million) in 2008 and PLN 28.4 million (EUR 6.5 million) in 2016. CONCLUSIONS: The prevalence rates of AD in Poland estimated on the basis of NHF data are significantly lower than those reported in previous epidemiological studies conducted in Poland and worldwide. This may indicate that the prevalence of AD in the Polish population is underestimated or that there are no adequate disease control measures in patients with a confirmed diagnosis.

A Ten-Year Longitudinal Study of Prevalence of Eating Disorders in the General Polish Type 2 Diabetes Population.

BACKGROUND Little has been reported regarding the epidemiology of eating disorders (EDs) in type 2 diabetes (T2DM). We examined the Polish National Health Fund-NFZ database estimates of all medical visits from 2008 to 2017 to determine the trend and the epidemiology of EDs in T2DM patients. MATERIAL AND METHODS The NFZ database were used. We defined the T2DM group diagnosed with both T2DM and EDs according to the ICD-10 codes. Demographic data were collected from the webpage of Statistics Poland (GUS). The annual prevalence of EDs was estimated according to the T2DM diagnosis status, and the age groups were stratified into 8 groups. RESULTS The prevalence of EDs in T2DM patients in the whole patient population with diagnosed T2DM ranged from 0.059% (in 2017) to 0.086% patients (in 2010). Differences in subcategories of EDs were noted. In the case of anorexia nervosa, a decreasing trend of coexistence with T2DM was noted. However, in the case of atypical anorexia nervosa, an increasing trend was observed. Both in the case of bulimia nervosa and atypical bulimia nervosa, an increasing trend of coexistence with T2DM was noted. As patients with T2DM age, the prevalence of EDs in T2DM decreased. CONCLUSIONS A relatively stable trend of prevalence of EDs in T2DM patients benefiting from state medical care indicated the need to develop effective screening methods and adequate procedures for therapeutic interventions with this group of patients using a multidisciplinary therapeutic team.

Sequentiality of treatment in the rheumatoid arthritis drug programme in the years 2009-2014.

Approximately 1% of the population suffers from rheumatoid arthritis (RA) worldwide (0.45% in Poland). The therapy consists of the use of disease-modifying antirheumatic drugs (DMARDs). Biologics are used in the form of the drug programme. Analysis of the NHF database demonstrated the sequence of conversion between drugs and time spent in a single treatment. In 2009, the patients would start the following treatments: adalimumab 5.8%; etanercept 14.4%; infliximab 23.1%; leflunomide 53.6%; rituximab 3%. After the first year 16% of patients changed therapy or abstained, and in the second year this situation affected 65% of patients. The following percentages maintained the same treatment in the last 6 years: infliximab 4%; adalimumab 15%; etanercept 21%; leflunomide on prescription was continued by 70%. Patients remain too long on the same therapy when it is inefficient. Achieving remission or low disease activity (DAS28 < 2.6) should take place within 6 months of starting therapy.

Analysis of survival of patients treated with vemurafenib, ipilimumab and dabrafenib for advanced skin melanoma in daily clinical practice (Real-World Data): retrospective analysis of patients treated under drug/reimbursement programmes in Poland in 2013-2016.

Vemurafenib, ipilimumab and dabrafenib were registered for the treatment of advanced skin melanoma pursuant to the results of randomized phase III clinical trials. Real-world data on survival time for patients treated with those drugs in daily clinical practice are so far limited. Patients with advanced skin melanoma treated under reimbursement programmes (drug programmes), for which they were qualified pursuant to uniform inclusion criteria in force in all oncology centres in Poland. Data were obtained from the electronic databases of the national payer (NFZ) responsible for the implementation and monitoring of reimbursement (drug) programmes. The analysis included all patients included for treatment with vemurafenib (since March of 2013), ipilimumab (since March of 2014) and dabrafenib (since July of 2015) until December 2016. The end date of the observation was set to 31 December 2016. The total survival analysis was performed using the Kaplan-Meier estimator. Until 31 December 2016, 759 patients were treated with vemurafenib, 370 with ipilimumab and 181 with dabrafenib. The overall survival (OS) median was 9.8 months for patients treated with vemurafenib (95% confidence interval: 8.8-10.6) and 6.9 months for patients treated with ipilimumab (95% confidence interval: 5.7-9.2). For patients treated with dabrafenib, the OS median was not reached because of an overly short observation period. The probability of surviving 12 months in the group of patients treated with vemurafenib was 40.5%, ipilimumab was 35.1% and dabrafenib was 60.7%. The probability of surviving 24 and 36 months in the group of patients treated with vemurafenib or ipilimumab amounted to, respectively, 20.1, 15.4 and 21, 18.8%. OS of patients with advanced melanoma treated in daily clinical practice may be comparable to the ones achieved in registration trials. The use of appropriate treatment inclusion criteria may affect the obtained OS.
