Abstract
OBJECTIVES To retrospectively analyze real-world treatment patterns in patients with relapsed/refractory multiple myeloma (RRMM) who initiated third-line treatment in Europe. METHODS German and Italian administrative claims data were sourced from the German AOK PLUS health insurance fund and Italian local health units (2016-2020). Data for the United Kingdom (UK), France, and Spain were sourced from medical chart reviews (MCRs) from 2016 to 2018 (historical) and 2019 to 2021 (new) using electronic case report forms. RESULTS Across all countries, immunomodulatory imide drug (IMiD)-based regimens were prominent in the third-line setting. From 2016 to 2020, lenalidomide-dexamethasone was most common in Italy (18.0%) and Germany (12.7%). From 2019 to 2021, the most common regimen was ixazomib-lenalidomide-dexamethasone (67.5%) in the UK, pomalidomide-dexamethasone (17.1%) in France, and daratumumab-bortezomib-dexamethasone (15.0%) in Spain. In the historical data (2016-2018), third-line lenalidomide- and pomalidomide-dexamethasone doublet use across the UK (>47%), France (>46%), and Spain (>33%) was high. From historical to new, triplet use increased in Spain (>19% to >60%) as did anti-CD38 agent use in France (15.1% to 51.9%) and Spain (19.7% to 42.1%). CONCLUSIONS From 2016 to 2021, third-line regimens were mostly IMiD based. The MCR data demonstrated evolving treatment choices from 2016 to 2018 and 2019 to 2021, providing insights into uptake of novel agents and current RRMM European clinical practice.

Abstract
Aim: This study assessed real-world treatment in patients with metastatic urothelial carcinoma (mUC) in Germany. Materials & methods: Patients diagnosed with mUC from 2015 to 2019 were identified in two claims databases: AOK PLUS and GWQ. Results: 3226 patients with mUC were analyzed; 1286 (39.9%) received systemic treatment within 12 months of diagnosis (platinum-based chemotherapy: 64.2%). Factors associated with receiving treatment were: younger age, male sex, less comorbidity and recent diagnosis. In AOK PLUS and GWQ populations, unadjusted median overall survival (interquartile range) from diagnosis in treated patients was 13.7 (6.8-32.9) and 13.8 (7.1-41.7) months, and in untreated patients was 3.0 (1.2-10.8) and 3.6 (1.2-18.8) months, respectively. Conclusion: A significant proportion of patients with mUC in Germany receive no systemic treatment.

Abstract
INTRODUCTION The objective of this study was to investigate the prevalence, incidence, and treatment patterns (treatment regimens, switches, duration) for diffuse large B-cell lymphoma (DLBCL) in a real-world setting. METHODS This was a retrospective German claims data analysis of patients with DLBCL diagnosed between January 1, 2012, and December 31, 2020. The prevalence and cumulative incidence of DLBCL were found for 2019/2020. Line of treatment (LOT) and treatment setting from first DLBCL diagnosis to end of follow-up were described. Kaplan-Meier overall survival (OS) estimates since DLBCL diagnosis and start of treatment lines were calculated. RESULTS Overall, 2633 incident DLBCL cases were identified (median age 75 years, 51% male). Of these, 2119 patients received at least one DLBCL-related treatment (LOT1), and 1567 patients died during follow-up. In 2019/2020, the prevalence and cumulative incidence of DLBCL was 34.8/36.7 per 100,000 patients and 14.0/12.7 per 100,000 patients, respectively. For LOT1, 1922 patients were given a chemotherapy-based regimen (1530 with CD20 antibodies). A total of 403 patients were administered a second line (LOT2), of which 183 patients received a CD20 antibody-containing chemotherapy regimen and 100 patients received stem cell transplantation or chimeric antigen receptor (CAR)-T therapy. Of the 136 LOT3+ treatments, 74 were chemotherapy regimens (54 with CD20 antibodies) and 18 were kinase inhibitors. The median time between treatment lines was less than 6 months. Among patients with at least LOT2, approximately 50% received more than one LOT during the first year after diagnosis. Approximately 25% of treated patients died within 6 months of treatment initiation. Of the 2633 included patients, the median OS from diagnosis was 31.0 months (treated patients: 46.8 months, untreated patients: 3.0 months). CONCLUSIONS Despite advances in the field, high unmet medical need in DLBCL remains. The treatment landscape is very heterogeneous, particularly in second- or later-line treatments, with few patients receiving potentially curative treatment beyond the first line. Treatment for DLBCL, particularly for transplant-ineligible patients, remains challenging.

Abstract
BACKGROUND This study aimed to describe treatment patterns and overall survival (OS) in patients with advanced non-small cell lung cancer (aNSCLC) in three countries between 2011 and 2020. METHODS Three databases (US, Canada, Germany) were used to identify incident aNSCLC patients. OS was assessed from the date of incident aNSCLC diagnosis and, for patients who received at least a first line of therapy (1LOT), from the date of 1LOT initiation. In multivariable analyses, we analyzed the influence of index year and type of prescribed treatment on OS. FINDINGS We included 51,318 patients with an incident aNSCLC diagnosis. The percentage of patients treated with a 1LOT differed substantially between countries, whereas the number of patients receiving immunotherapies/targeted treatments increased over time in all three countries. Median OS from the date of incident diagnosis was 9.9 months in the United States vs. 4.1 months in Canada. When measured from the start of 1LOT, patients had a median OS of 10.7 months in the United States, 10.9 months in Canada, and 10.9 months in Germany. OS from the start of 1LOT improved in all three countries from 2011 to 2020 by approximately 3 to 4 months. CONCLUSIONS Observed continuous improvement in OS among patients receiving at least a 1LOT from 2011 to 2020 was likely driven by improved care and changes in the treatment landscape. The difference in the proportion of patients receiving a 1LOT in the observed countries requires further investigation.

Abstract
AIMS This retrospective claims data study characterized real-world treatment patterns, healthcare resource utilization (HCRU), and costs in patients with metastatic urothelial carcinoma (mUC) in Germany. MATERIALS AND METHODS Continuously insured adults with incident mUC diagnosis (=index; ICD-10: C65-C68/C77-C79) in 2015-2019 were identified from two German claims databases. Patients who received first-line (1 L) treatment within 12 months of index were divided into three mutually exclusive sub-cohorts: platinum-based chemotherapy (PB-CT), non-PB-CT, and immunotherapy (IO). Patient characteristics were assessed during a 24-month baseline period; treatments, HCRU, and costs (of the health insurance fund) per patient-year (ppy) were described during 12-month follow-up. RESULTS We identified 3,226 patients with mUC (mean age, 73.8 years; male, 70.8%; mean Elixhauser Comorbidity Index, 17.6); 1,286 (39.9%) received 1 L treatment within 12 months of index. Of these, 825 (64.2%) received PB-CT, 322 (25.0%) non-PB-CT, and 139 (10.8%) IO. On average, treated patients had 5.1 hospitalizations ppy. Most UC-related hospitalizations ppy were observed in the PB-CT cohort (5.8), followed by the non-PB-CT (4.2) and IO (2.3) cohorts. Mean UC-related hospitalization costs ppy were €22,218 in the treated cohort, €24,294 in PB-CT, €19,079 in IO, and €18,530 in non-PB-CT cohorts. Cancer-related prescription costs ppy averaged €6,323 in treated patients, and €25,955 in IO, €4,318 in non-PB-CT, and €4,270 in PB-CT cohorts. LIMITATIONS We recognized limitations in our study's sample selection due to unavailable mUC disease status data. We addressed this through an upstream feasibility study conducted in consultation with clinical experts to determine a suitable proxy. Proxies were also used to delineate treatment lines, switches, and discontinuations due to data absence. Furthermore, due to data restrictions, collective dataset analysis was not possible, prompting a meta-analysis for pooled results. CONCLUSIONS The study shows that mUC is associated with significant HCRU and costs across different types of 1 L systemic therapy.

Abstract
Background The Expanded Disability Status Scale (EDSS) quantifies disability and measures disease progression in multiple sclerosis (MS), however is not available in administrative claims databases. Objectives To develop a claims-based algorithm for deriving EDSS and validate it against a clinical dataset capturing true EDSS values from medical records. Methods We built a unique linked dataset combining claims data from the German AOK PLUS sickness fund and medical records from the Multiple Sclerosis Management System 3D (MSDS3D). Data were deterministically linked based on insurance numbers. We used 69 MS-related diagnostic indicators recorded with ICD-10-GM codes within 3 months before and after recorded true EDSS measures to estimate a claims-based EDSS proxy (pEDSS). Predictive performance of the pEDSS was assessed as an eight-fold (EDSS 1.0-7.0, ≥8.0), three-fold (EDSS 1.0-3.0, 4.0-5.0, ≥6.0), and binary classifier (EDSS <6.0, ≥6.0). For each classifier, predictive performance measures were determined, and overall performance was summarized using a macro F1-score. Finally, we implemented the algorithm to determine pEDSS among an overall cohort of patients with MS in AOK PLUS, who were alive and insured 12 months prior to and after index diagnosis. Results We recruited 100 people with MS insured by AOK PLUS who had ≥1 EDSS measure in MSDS3D between 01/10/2015 and 30/06/2019 (620 measurements overall). Patients had a mean rescaled EDSS of 3.2 and pEDSS of 3.0. The pEDSS deviated from the true EDSS by 1.2 points, resulting in a mean squared error of prediction of 2.6. For the eight-fold classifier, the macro F1-score of 0.25 indicated low overall predictive performance. Broader severity groupings were better performing, with the three-fold and binary classifiers for severe disability achieving a F1-score of 0.68 and 0.84, respectively. In the overall AOK PLUS cohort (3,756 patients, 71.9% female, mean 51.9 years), older patients, patients with progressive forms of MS and those with higher comorbidity burden showed higher pEDSS. Conclusion Generally, EDSS was underestimated by the algorithm as mild-to-moderate symptoms were poorly captured in claims across all functional systems. While the proxy-based approach using claims data may not allow for granular description of MS disability, broader severity groupings show good predictive performance.

Abstract
BACKGROUND Alpha-1 antitrypsin deficiency is a rare genetic disease and a leading cause of inherited alterations in plasma protein metabolism (APPM). AIM To understand the prevalence, burden and progression of liver disease in patients with APPM including alpha-1 antitrypsin deficiency. METHODS We conducted a retrospective analysis of anonymized patient-level claims data from a German health insurance provider (AOK PLUS). The APPM cohort comprised patients with APPM (identified using the German Modification of the International Classification of Diseases-10th Revision [ICD-10-GM] code E88.0 between 01/01/2010-30/09/2020) and incident liver disease (ICD-10-GM codes K74, K70.2-3 and K71.7 between 01/01/2012-30/09/2020). The control cohort comprised patients without APPM but with incident liver disease. Outcomes were incidence/prevalence of liver disease in patients with APPM, demographics/baseline characteristics, diagnostic procedures, progression-free survival (PFS), disease progression and mortality. RESULTS Overall, 2680 and 26299 patients were included in the APPM (fibrosis, 96; cirrhosis, 2584) and control (fibrosis, 1444; cirrhosis, 24855) cohorts, respectively. Per 100000 individuals, annual incidence and prevalence of APPM and liver disease was 10-15 and 36-51, respectively. In the APPM cohort, median survival was 4.7 years [95% confidence interval (CI): 3.5-7.0] and 2.5 years (95%CI: 2.3-2.8) in patients with fibrosis and cirrhosis, respectively. A higher proportion of patients in the APPM cohort experienced disease progression (92.0%) compared with the control cohort (67.2%). Median PFS was shorter in the APPM cohort (0.9 years, 95%CI: 0.7-1.1) compared with the control cohort (3.7 years, 95%CI: 3.6-3.8; P < 0.001). Patients with cirrhosis in the control cohort had longer event-free survival for ascites, hepatic encephalopathy, hepatic failure and esophageal/gastric varices than patients with cirrhosis in the APPM cohort (P < 0.001). Patients with fibrosis in the control cohort had longer event-free survival for ascites, cirrhosis, hepatic failure and esophageal/gastric varices than patients with fibrosis in the APPM cohort (P < 0.001). In the APPM cohort, the most common diagnostic procedures within 12 mo after the first diagnosis of liver disease were imaging procedures (66.3%) and laboratory tests (51.0%). CONCLUSION Among patients with liver disease, those with APPM experience substantial burden and earlier liver disease progression than patients without APPM.

Abstract
INTRODUCTION Hydrochlorothiazide (HCT) has been suggested to induce photosensitivity, thereby increasing the incidence of skin cancers. After a pharmacovigilance alert, HCT was frequently withdrawn or substituted by other diuretics. The aim of this study was to compare the association of exposure to HCT with cancer risk versus alternative diuretics. METHODS A retrospective cohort study was conducted based on data from the AOK PLUS, a large German statutory health insurance fund. Patients with HCT treatment were propensity score matching to patients using non-HCT diuretics. Incidence of cancer of any kind and, specifically, skin cancer was assessed in both groups. Time-to-incident cancer diagnosis was evaluated and compared between the groups. RESULTS A total of 199 708 patients were included in the final analysis ( n = 76 855 in the HCT group; n = 122 853 in the non-HCT-diuretics group). After propensity score matching, 122 554 patients remained in the sample ( n = 61 277 for both groups, of which >96% had hypertension, mean age 73 years, 61% female). HCT treatment was associated with a lower incidence of cancer of any kind compared with non-HCT diuretics (incidence rate ratio per 100 patient years 0.84 95% confidence interval: 0.82-0.87). HCT treatment was associated with a small albeit significantly higher incidence rate ratio of skin cancer (1.15 95% confidence interval: 1.06-1.24) with significant variances over time. Although numerically higher, the difference accounts to only 0.05 more skin cancer diagnoses in 100 patient-years. CONCLUSION HCT treatment compared with alternative diuretics was associated with a lower all-cancer risk and a numerically small increased skin cancer risk in a large German population. Risk-benefit evaluation should be executed in patients with increased skin cancer risk and treatment with HCT. Furthermore, advice for skin protection is warranted in all patients taking thiazide or thiazide-like diuretics.

Abstract
BACKGROUND AND OBJECTIVES Psoriasis is a common skin disorder with a high physical and psychological burden for patients. Up to 30% of the patients are candidates for a systemic treatment. The aim of this study was to describe the characteristics and the real-world systemic treatment of psoriasis patients. PATIENTS AND METHODS This study was based on German medical claims data. A cross-sectional analysis observed all psoriasis patients in 2020. A longitudinal analysis was conducted, addressing psoriasis patients who newly started a systemic treatment. RESULTS In total, 116,507 prevalent psoriasis patients and 13,449 newly treated patients were followed. Of all prevalent patients, 15.2% received systemic treatment in 2020 (8.7% systemic corticosteroids). Of the newly treated patients, 95.2% started with conventional treatment (79.2% systemic corticosteroids), 4.0% with biologics and 0.9% with apremilast. The rate of treatment discontinuation/switch after one year was highest for corticosteroids (91.3%) and lowest for biologics (23.1%). CONCLUSIONS Around 15% of psoriasis patients in Germany received a systemic treatment, with > 50% of these prescribed systemic corticosteroids. Therefore, we conclude that systemic treatment is not in line with guideline recommendations in a substantial number of observed patients. The lowest discontinuation/switch rates for biologics support their wider use.

Abstract
PURPOSE The aim of this study was to investigate the burden of disease among a real-world cohort of patients with prevalent Crohn's disease (CD) in Germany. METHODS We conducted a retrospective cohort analysis using administrative claims data from the German AOK PLUS health insurance fund. Continuously insured patients with a CD diagnosis between 01 October 2014 and 31 December 2018 were selected and followed for at least 12 months or longer until death or end of data availability on 31 December 2019. Medication use (biologics, immunosuppressants (IMS), steroids, 5-aminosalicylic acid) was assessed sequentially in the follow-up period. Among patients with no IMS or biologics (advanced therapy), we investigated indicators of active disease and corticosteroid use. RESULTS Overall, 9284 prevalent CD patients were identified. Within the study period, 14.7% of CD patients were treated with biologics and 11.6% received IMS. Approximately 47% of all prevalent CD patients had mild disease, defined as no advanced therapy and signs of disease activity. Of 6836 (73.6%) patients who did not receive advanced therapy in the follow-up period, 36.3% showed signs of active disease; 40.1% used corticosteroids (including oral budesonide), with 9.9% exhibiting steroid dependency (≥ 1 prescription every 3 months for at least 12 months) in the available follow-up. CONCLUSIONS This study suggests that there remains a large burden of disease among patients who do not receive IMS or biologics in the real world in Germany. A revision of treatment algorithms of patients in this setting according to the latest guidelines may improve patient outcomes.

Abstract
Myasthenia gravis (MG) is a rare, chronic autoimmune disease with symptoms of fluctuating muscular weakness and fatigability. The aim of this retrospective cohort study was to estimate the prevalence and incidence of MG in Germany, and to understand the burden of disease and treatment patterns, based on anonymized German claims data. Two patient samples were identified: (1) incident MG patients with newly onset disease between 2015 and 2019, and (2) prevalent MG patients in 2019. In total, 775 incident MG patients with a mean age of 66.9 years; and 1,247 prevalent MG patients with a mean age of 68.6 years were included. The prevalence for Germany was estimated to be 39.3/100,000 on 31/12/2019; the incidence in 2019 was 4.6 cases/100,000 persons. The 12-month mortality was 5.7. For 31.5% of the incident patients, no MG treatment was observed in the first year after the index date. Of all incident patients, 29.9% experienced an exacerbation, and 6.7% a myasthenic crisis during the observation. Our study indicates that a substantial proportion of MG patients remains untreated. Many MG patients still experience exacerbations / MG crises. MG seems to be associated with an excess mortality in comparison to the general non-MG population.

Abstract
BACKGROUND Research suggests that serious infections (SIs), comorbidities, and advanced disability represent key drivers of early death in people with Multiple Sclerosis (pwMS). Nevertheless, further research is warranted to better characterize and quantify the risk of SI among pwMS compared to the general population. METHODS Our study consisted of a retrospective analysis of claims data provided by a German statutory health insurance fund, AOK PLUS, covering 3.4 million individuals in Saxony and Thuringia from 01/01/2015-31/12/2019. A propensity score (PS) matching method was used to compare the incidence of SIs among people with and without MS. PwMS were required to have ≥1 inpatient or ≥2 confirmed outpatient diagnoses of MS (ICD-10 G35) from a neurologist from 01/01/2016-31/12/2018, while people from the general population could not have any inpatient/outpatient codes for MS during the entire study period. The index date was defined as the first observed MS diagnosis or, in the case of the non-MS cohort, a randomly assigned date within the inclusion period. For both cohorts a PS was assigned, corresponding with their probabilistic likelihood of having MS based on observable factors including patient characteristics, comorbidities, medication use and other variables. People with and without MS were matched using a 1:1 nearest neighbor strategy. An exhaustive list of ICD-10 codes was created in association with 11 main SI categories. SIs were those recorded as the main diagnosis during an inpatient stay. ICD-10 codes from the 11 main categories were sorted into smaller classification units, used to distinguish between infections. A 60-day threshold for measuring new cases was defined to account for the potential risk of re-infection. Patients were observed until the end of the study period (31/12/2019) or death. Cumulative incidence, incidence rates (IRs) and IR ratios (IRRs) were reported during follow-up and at 1-, 2- and 3-years post-index. RESULTS A total of 4250 and 2,098,626 patients were included in the unmatched cohorts of people with and without MS. Ultimately, one match was identified for all 4,250 pwMS, corresponding with a final population of 8,500 patients. On average, patients were 52.0/52.2 years in the matched MS/non-MS cohorts; the gender breakdown was 72% female. Overall, IRs of SIs per 100 patient years (PY) were higher in pwMS than in those without MS (1 year: 7.6 vs. 4.3; 2 years: 7.1 vs. 3.8; 3 years: 6.9 vs. 3.9). During follow-up, the most common infection types in pwMS were of a bacterial/parasitic origin (2.3 per 100 PY), followed by respiratory (2.0) and genitourinary (1.9) infections. Respiratory infections were most common in patients without MS (1.5 per 100 PY). Differences in the IRs of SIs were statistically significant (p<0.01) at each measurement window, with IRRs ranging from 1.7-1.9. PwMS had a higher risk of hospitalized genitourinary infections (IRR: 3.3-3.8) and bacterial/parasitic infections (2.0-2.3). CONCLUSIONS The incidence of SIs is much higher in pwMS, than comparators from the general population in Germany. Differences in hospitalized infection rates were largely driven by higher levels of bacterial/parasitic and genitourinary infections in the MS population.

Abstract
464 Background: This study assessed real-world treatment (tx) and outcomes in patients with metastatic urothelial carcinoma (mUC) in Germany. Methods: Using 2 statutory health insurance (SHI) claims databases (SHI 1 and SHI 2; 2013-2020, ≈8 million insured), adults with an incident mUC diagnosis from 2015-2019 were identified. Those with other malignant tumors were excluded. Patients were observed for ≥12 mo after incident mUC diagnosis (index) or until death. Treated patients were delineated into 3 groups based on first-line (1L) tx received: platinum-based chemotherapy (PB CT), non–PB CT, and immunotherapy (IO). Patient characteristics were analyzed descriptively. Multivariable logistic regression was used to identify factors associated with receiving tx. Overall survival (OS) was calculated from 1L tx initiation by Kaplan-Meier estimation. Analyses were done separately for each database. Results: The study included 3,226 patients with mUC (male, 70.8%), with a mean (SD) follow-up of 13.8 mo (16.1). The mean (range) age was 73.8 y (23-99), and the mean (SD) Elixhauser Comorbidity score was 17.6 (11.4). Overall, 1,286 patients (39.9%) received tx in the first 12 mo post index; PB CT was the most common 1L tx (n=825, 64.2%), followed by non–PB CT (n=322, 25.0%) and IO (n=139, 10.8%). Over time, the number of patients receiving 1L tx increased (2015, 35.8%; 2019, 45.7%). Multiple factors were associated with a higher likelihood of receiving 1L tx: younger age (OR, 0.93), male sex (OR, 0.83), lower comorbidity score (OR, 0.97), previous UC-related interventions (OR, 1.65), and a more recent mUC diagnosis (OR, 1.11). In treated patients, the unadjusted median OS (interquartile range [IQR]) from index diagnosis was 13.7 mo (7-33) for SHI 1 and 13.8 mo (7-42) for SHI 2. In untreated patients, the median OS (IQR) from index diagnosis was 3.0 mo (1-11) for SHI 1 and 3.6 mo (1-18) for SHI 2. The median OS (IQR) after 1L tx initiation in PB CT–treated patients was 12.9 mo (6-33) for SHI 1 and 13.8 mo (7-49) for SHI 2; in non–PB CT–treated patients was 11.2 mo (4-36) for SHI 1 and 6.5 mo (3-15) for SHI 2; and in IO-treated patients was 4.11 mo (2-14) for SHI 1 and 8.19 mo (3 to not reached) for SHI 2. Conclusions: Our study describes real-world tx patterns/rates and clinical outcomes in patients with mUC in Germany, and highlights that the majority received no systemic tx within the first 12 mo, despite a positive trend in 1L tx rates over time. Treated patients were more likely to be younger, male, and have fewer comorbidities vs untreated patients. Systemic tx was associated with longer OS. Among treated patients, OS was longer in those receiving 1L PB CT vs other 1L tx. Future research should explore the unmet need in untreated patients to confirm alignment with updated tx guidelines and newer standards of care.

Abstract
Background: This study aimed to evaluate differences in healthcare resource utilization and cost among patients with controlled and uncontrolled asthma.Methods: Claims data from a German sickness fund was linked to patient survey data. Outpatient physicians enrolled patients and assessed asthma control using the ACTTM questionnaire. All-cause and asthma-specific healthcare resource use (HCRU)/costs were compared descriptively and based on multivariable models using a continuous ACTTM score.Results: Overall, 492 asthma patients were included (mean age: 53.8, 73.8% female). The mean/median ACTTM score was 19.9/20.7, with 183 patients (37.2%) classified as having uncontrolled asthma (mean ACTTM score<20) Patients with uncontrolled asthma had significantly more hospitalizations (p = .035) and medication prescriptions (p < .001), which resulted in higher total healthcare costs for asthma-related (€1785 vs. €1615; p = .004) and all-cause care (€4695 vs. €4117; p = .009). While controlling for baseline characteristics, multivariable models confirmed a negative association between asthma control and total all-cause healthcare costs (p = .008), total asthma-related costs (p = .008), and costs of medication prescriptions (p = .001). However, no significant association was found for all-cause (p = .062) and asthma-related hospitalization costs (p = .576).Conclusion: Considering continuous patient care, improving asthma control is not only desirable from a clinical perspective, but could also be an effective approach to reduce asthma-related HCRU and cost burden.

Abstract
Status epilepticus is a life-threatening emergency, and to date, few studies have reported on its long-term treatment and outcomes. This study aimed to estimate the incidence, the treatment and outcomes, the healthcare resource utilization and the costs of status epilepticus in Germany. Data from 2015 to 2019 were obtained from German claims (AOK PLUS). Patients with ≥1 status epilepticus event and no event in the preceding 12 months (baseline) were included. A subgroup of patients with an epilepsy diagnosis during baseline was also analysed. Of the 2782 status epilepticus patients (mean age = 64.3 years; 52.3% female), 1585 (57.0%) were previously diagnosed with epilepsy. The age- and sex-standardized incidence was 25.5 cases/100 000 persons in 2019. The mortality rate after 12 months was 39.8% overall (19.4% and 28.2% after 30 and 90 days, respectively) and 30.4% in the epilepsy patient subgroup. Factors associated with higher mortality were age, comorbidity status, presence of brain tumours and an acute stroke. An epilepsy-related hospitalization at onset of or 7 days prior to the status epilepticus event as well as prescription of antiseizure medication during baseline was associated with a better survival rate. Overall, 71.6% of patients (85.6% in the epilepsy subgroup) were prescribed with out-patient antiseizure medication and/or rescue medication within 12 months. All patients sustained on average 1.3 status epilepticus-related hospitalizations (20.5% had more than one) during a mean follow-up period of 545.2 days (median 514 days); total direct costs including in-patient and out-patient status epilepticus treatments were 10 826€ and 7701€ per patient-year overall and for the epilepsy patient subgroup, respectively. The majority of status epilepticus patients received an out-patient treatment in line with epilepsy guidelines, and patients previously diagnosed with epilepsy have a higher likelihood to receive it. The mortality in the affected patient population is high; risk factors were older age, higher comorbidity burden, the presence of brain tumours or an acute stroke.

Abstract
BACKGROUND People with multiple sclerosis (pwMS) have a higher risk of serious infection (i.e., infection-related hospitalizations) than people without MS. Few studies have explored the risk of serious infections by MS phenotype in a real-world setting. This retrospective study compared the incidence of serious infections among people with relapse remitting MS (RRMS), primary progressive MS (PPMS), and secondary progressive MS (SPMS). METHODS Adult pwMS were selected from a German claims database, based on one inpatient or two outpatient diagnoses of MS (ICD-10 G35) by a neurologist from 01/01/2016 to 12/31/2018. Three cohorts (RRMS, PPMS, SPMS) were identified based on codes for MS subtypes included in the German Modification of the ICD-10 system. A fourth cohort of unspecified MS patients combined those with conflicting MS subtype diagnoses and multiple unspecified codes for MS. Serious infections were defined as hospitalizations for which infections were selected as the primary inpatient diagnosis. Infections were identified from a basket of ICD-10 codes distributed across 11 main categories, according to possible pathogen (e.g., other bacterial diseases [A30-A49]) or anatomical location (e.g., urinary tract infection [N39.0]). Multiple infections were counted if an interval of at least 60 days was recorded between episodes. Serious infections were counted from index (i.e., first recorded MS code) until the end of the study period or death. Incidence rates (IRs) were reported per 100 patient years (PY). RESULTS A total of 4,250 pwMS (RRMS: 2,307, PPMS: 282, SPMS: 558, unspecified MS: 1,135) were included; 32 patients progressed from RRMS to SPMS during the follow-up period. Mean (SD) age at baseline was 46.6 (13.6), 61.9 (12.4), and 62.5 (11.8) years in patients with RRMS, PPMS, and SPMS, respectively. Most pwMS were female (RRMS 74.8%, PPMS 62.1%, SPMS 67.4%). Progressive pwMS were more likely to have at least 1 comorbidity (PPMS 87.2%, SPMS 87.5%) compared to those with relapsing MS (61.9%). Most RRMS patients received disease-modifying therapy during follow-up (82.1%), while less than half of progressive MS patients did (PPMS 23.8%, SPMS 31.4%). Over a mean (SD) follow-up period of 3.5 (0.8) years, the IR of serious infections per 100 PY was higher in progressive MS cohorts (PPMS 13.5 [11.3-16.1], SPMS 13.6 [12.0-15.3]) than in the RRMS group (3.4 [3.0-3.7]). Yearly IRs remained stable over time in each cohort. Where anatomical location was specified, respiratory (2.0 per 100 PY) and genitourinary (1.9 per 100 PY) infections were most common. Across all subtypes, higher rates of serious infections were observed in men and older patients. CONCLUSION Progressive MS, older age and male sex are associated with an increased risk of serious infections. Overall, respiratory and genitourinary infections were the most commonly reported serious infections.

Abstract
BACKGROUND AND OBJECTIVES Although vaccine preventable, the incidence of tick-borne encephalitis (TBE) increased in Germany from 2001 to 2021 by on average 2% each year, with a peak of more than 700 TBE infections documented in 2020. TBE-risk areas, as designated by district based on incidence of human cases, expanded north- and northeastward, present in 11 of the 16 Federal States as of 2022. Using claims data from a German statutory health insurance in the Federal States of Saxony and Thuringia (AOK PLUS), we aimed to assess whether official assignment of a district to a risk area had an impact on vaccination rates in Germany. METHODS The data covered the period from 01/01/2010 to 31/12/2018 and included information on vaccine administrations from outpatient physicians. Yearly incident vaccination rates were reported overall and by district. To investigate the association between a new designation of an incident TBE-risk area and vaccination rates, a difference-in-difference analysis was conducted. RESULTS Overall, the incident vaccination rates increased from 6.2 to 9.5 per 1,000 person-years between 2012 and 2018, with a peak of 12.2 in 2015. While districts that had been risk-areas for the whole study period had always a higher vaccination rate compared to districts that were never categorized as risk areas, the increase between 2012 and 2018 was comparable in the two groups (3.0 and 3.2 per 1,000 person-years, respectively). In contrast, districts that were newly designated risk districts during the study period experienced a significantly larger increase in vaccination rates, going from 5.8 to 14.7 per 1,000 person-years between 2012 and 2018, with a peak of 19.6 in 2015. CONCLUSION The results suggest that the new designation of a district as risk area has a significant positive impact on vaccination rates, which is strongest immediately after designation of risk area.

Abstract
BACKGROUND Asthma causes various clinical symptoms, including unpredictable severe exacerbations, and even though most patients can achieve a reasonable disease control due to adequate treatment, some patients do not. This study seeks to describe healthcare resource utilization (HCRU) and treatment of asthma and severe asthma patients in Germany. METHOD A retrospective claims data analysis has been conducted on adult asthma patients and a subset of patients with severe asthma, identified during July 2017 - June 2018. A proxy was used to identify severe asthma patients based on therapy options recommended within the German treatment guideline for treating these patients. These include (i) biologics, (ii) medium/high-dose inhaled corticosteroids (ICS) in conjunction with LABA/montelukast and antibiotics/oral corticosteroids (OCS), and (iii) long-term OCS therapy. HCRU and treatment of patients were observed during a 1-year follow-up period (July 2018 - June 2019). RESULTS The study included 388 932 adult asthma patients (prevalence: 7.90%), with 2.51%-12.88% affected by severe asthma (depending on the definition). 22.60% of all asthma patients experienced hospitalizations (severe asthma: 36.11%). Furthermore, 13.59% received OCS (severe asthma: 39.91%), but only 0.18% (severe asthma: 1.25%) received biologics. Only 23.95% (severe asthma: 41.17%) visited a pulmonologist. CONCLUSIONS A considerable proportion of severe asthma patients receive long-term OCS therapy. However, less than 50% have seen a pulmonologist who would typically seek a change in treatment to avoid the long-term consequences of OCS. To optimize the treatment of severe asthma in Germany, better referral of these patients to specialists is needed and considering potential treatment alternatives.

Abstract
BACKGROUND The positioning of new biologic agents for the treatment of Crohn's disease (CD) following failure of initial anti-tumor necrosis factor (anti-TNF) therapy remains a challenge in the real world. OBJECTIVES This study aims to investigate the real-world outcomes associated with the sequential use of biologics in CD patients that newly initiate anti-TNFs, specifically comparing those that switch to another anti-TNF versus biologics with other modes of action. DESIGN Retrospective cohort study. METHODS We identified CD patients who newly began anti-TNF therapy between 1 October 2014 and 31 December 2018 using two German claims databases. Patients were classified as within-class switchers (WCS) if they switched to another anti-TNF or outside-class switchers (OCS) if they switched to vedolizumab (VDZ) or ustekinumab (UST). To compare WCS and OCS, baseline covariates were adjusted through inverse probability of treatment weighting (IPTW), and time-to-event analyses were performed using Cox Proportional Hazard regressions. Results from both databases were meta-analyzed using an inverse variance model. RESULTS Overall, 376 prevalent adult CD patients who initiated anti-TNFs and switched to another biologic were identified. After IPTW, there were 152 and 177 patients in the WCS and OCS group, respectively. WCS were more likely to receive prolonged corticosteroid therapy [hazard ratio (HR): 1.63, 95% confidence interval (CI): 1.17-2.27, p = 0.004], switch a second time to a different biologic (HR: 2.44, 95% CI: 1.63-3.66, p < 0.001), and discontinue treatment (HR: 1.71, 95% CI: 1.25-2.34, p = 0.001) than OCS. CONCLUSION This study suggests that CD patients exhibit more favorable outcomes when switching outside the anti-TNF class to VDZ or UST after initial anti-TNF failure than switching to a second anti-TNF. With loss of response to anti-TNFs as a concern in the real world, comparative evidence from claims data assessing sequential use of biologics can help optimize treatment algorithms of patients after anti-TNF failure.

Abstract
Abstract
Objective
Current guidelines for the management of arterial hypertension, dyslipidemia, or secondary cardiovascular (CV) prevention recommend combination drug treatments with single pill combinations (SPC). This concept is expected to improve adherence to treatment and, as a consequence, to reduce the risk of adverse CV outcomes associated with these clinical conditions. Aim of our study was to assess whether SPC are clinically superior to multi pill combination (MPC) with identical drugs in reducing CV events and al-cause mortality in a huge population under real world conditions in daily practice.
Methods
We analyzed an anonymized claims dataset (AOK PLUS, a statutory German sickness fund) including patients with hypertension and other CV diseases in the years 2012–2017; minimum follow-up was 1 year or until date of death, After 1:1-Propensity Score Matching (PSM), selected CV outcomes (myocardial infarction, stroke, transitory ischemic attack, coronary artery disease, heart failure, acute renal failure, cardiovascular hospitalization, all cause hospitalization) as well as all-cause mortality were compared using Incidence Rate Ratios (IRRs) and non-parametric tests.
Results
50,622 patients (25,311 patients in SPC versus MPC group) aged ≥18 years treated with SPC or identical MPC were followed up for at least 1 year or until death. No significant differences in baseline characteristics were observed after PSM. Nine different clinical outcomes were compared for each group. In all comparisons, significantly lower incidence rate ratios (IRR) were identified for SPC, confirmed by comparison of Kaplan-Meier estimates: stroke (IRR=0.77; 95% CI 0.67–0.88; p<0.001), transitory ischemic attack (IRR=0.61; 95% CI 0.48–0.78; p<0.001), myocardial infarction (IRR=0.76; 95% CI 0.63–0.90; p=0.0016), coronary artery disease (IRR=0.66; 95% CI 0.57–0.77; p<0.001), heart failure (IRR=0.59; 95% CI 0.54–0.64; p<0.001), acute renal failure (IRR=0.54; 95% CI 0.56–0.64; p<0.001) all cause hospitalization (IRR=0.72; 95% CI 0.71–0.74; p<0.001), cardiovascular hospitalization (IRR=0.63; 95% CI 0.57–0.69; p<0.001), and all-cause mortality (IRR=0.62; 95% CI 0.57–0.68; p<0.001). The mean time to first events and time to death were also in favor to SPC (any event: SPC 966.052 days/median 873; MPC 846.936 days/median 647; death: SPC 1,719.424 days; MPC 1,657.248 days; log rank for both comparisons: p<0.001).
Conclusion
In clinical practice, the SPC regimen is associated with a lower incidence of CV events and lower all-cause mortality. Time to the event is also significantly longer in the SPC group compared to MPC. These results strongly support the concept of SPC and the implementation into daily practice to improve patient's prognosis.

Abstract
Purpose This study aimed to describe the real-world treatment of German incident COPD patients, compare that treatment with clinical guidelines, and provide insight into disease development after incident diagnosis. In addition, the economic burden of the disease by assessing COPD-related healthcare costs was described. Patients and Methods Based on a German claims dataset, continuously insured individuals (04/2014-03/2019) aged 40 years or older with at least two incident pulmonologist's diagnoses or one inpatient diagnosis of COPD (ICD-10-GM code J44.-; no respective diagnosis in a 12-month baseline period) were selected. Treatment patterns after incident diagnosis considering inhaled maintenance therapies identified by ATC codes (outpatient prescriptions) were analyzed. Prescription patterns were compared with recommendations of German COPD treatment guidelines. Severe exacerbations were assessed as hospitalizations with main diagnosis ICD-10-GM code J44.1. COPD-associated costs from the perspective of the health insurance fund AOK PLUS were calculated per patient-year (PY). Results The sample comprised 17,464 incident COPD patients with a mean age of 71.5 years. 58.9% were male and the mean Charlson-Comorbidity-Index was 5.3. During follow-up (median: 2.0 years), 57.1% of the patients received at least one prescription of an inhaled maintenance therapy, whereas 42.9% did not. Among treated patients, 35.2% started their treatment with LABA/LAMA, 25.3% with LAMA monotherapy, 16.2% with LABA/ICS, and 7.8% with LABA/LAMA/ICS therapy. Within four weeks after initial diagnosis, ICS-containing therapies were prescribed in 14.1% of patients. Of all patients with a prescribed triple therapy, 68.9% had no corresponding exacerbation history documented. On average, 0.16 severe exacerbations and 0.19 COPD-related hospitalizations were observed per PY during available follow-up. Direct COPD-related costs were 3,693 €/PY, with COPD-related hospitalizations being responsible for about 79.2% of these costs. Conclusion Long-acting bronchodilators are the mainstay of pharmacological treatment of incident COPD patients in Germany, in line with guideline recommendations. Yet, a considerable proportion of incident COPD patients did not receive any inhaled maintenance therapy.

Abstract
BACKGROUND There are different levels of severity among patients who suffer from chronic rhinosinusitis with nasal polyps (CRSwNP). In this study, the epidemiology of CRSwNP and severe CRswNP was estimated. METHODS A retrospective claim data analysis was conducted on adult CRSwNP patients (ICD-10: J33), and those classified as severe CRSwNP patients with inadequate disease control (based upon combinations of previous and current treatments) between 2015 and 2019. Prevalence and incidence figures were calculated and extrapolated to the German population. In addition, baseline characteristics and treatment outcomes were analysed. RESULTS Overall, the 5-year prevalence of adult CRSwNP cases from 2015 to 2019 in Germany was 374,115 cases (about 5500 per million), with 12,989 (about 200 per million) patients being classified as severe CRSwNP with inadequate disease control, whereas 267,880 (about 3900 per million) patients were identified as having an incident CRSwNP diagnosis between 2016 and 2019. From the incident CRSwNP cohort, 80.55% had received at least one intranasal corticosteroid (INCS), 24.27% received at least 1 systemic corticosteroid (SCS), and 17.33% received at least one functional endoscopic sinus surgery (FESS) within 12 months after their incident diagnosis. CONCLUSION Severe CRSwNP with inadequate disease control affects about 200 per million people in Germany. INCS is the first-choice treatment for most CRSwNP patients; however, for patients with severe CRSwNP, SCS are prescribed more frequently and long-term effects of these should be further investigated, especially if despite treatment, adequate disease control cannot be achieved.

Abstract
PURPOSE Endometrial cancer (EC) is the sixth most common malignancy among females worldwide. Due to limited therapeutic options, treatment of advanced or recurrent disease is associated with poor outcomes. The aim of this study was to describe the real-world treatment of patients with advanced or recurrent EC who received a systemic treatment following platinum-based chemotherapy. METHODS This retrospective cohort study was based on anonymized German claims data covering the period between January 1, 2010, and June 30, 2020. Patients with EC who started an anticancer treatment following platinum-based chemotherapy were observed for a minimum follow-up of 12 months. Available claims data were used to describe patient characteristics, subsequent treatment lines, healthcare resource utilization, and overall survival (OS) of patients. RESULTS Out of 713 patients with advanced or recurrent EC and who had received a platinum-based treatment, 201 (mean age: 68.9 years) with a post-platinum-based treatment were identified and observed. The median OS in this population was 335.0 days. Of the 201 patients, 79 patients (39.3%) received a second line of treatment (LOT), and 21 patients (10.4%) had 3 or more treatment lines. In the LOTs following platinum-based chemotherapy, more than 70 different treatment regimens were observed. The hospitalization rate was generally high, with 5.2 hospitalizations per patient-year in the follow-up period. CONCLUSION The wide variety of therapeutic regimens applied in patients in Germany who progressed after platinum-based therapy confirms the lack of therapeutic strategy for these patients, and the poor prognosis highlights the urgent need for new treatment strategies.

Abstract
Aim: This study assessed whether a single pill combination (SPC) is associated with lower direct healthcare costs. Materials & methods: Anonymized claims data of patients ≥18 years treated with drugs for cardiovascular (CV)-related diseases either as a single pill combination or multi-pill combination (follow-up to 1 year) were evaluated. After propensity score matching, 59,336 out of 1,369,840 patients were analyzed. Results: In all cohorts, patients receiving a single pill combination had a lower frequency of general practitioner and specialist visits. The patients also had a significantly lower ratio of all-cause hospitalization days and number of CV-related prescriptions as well as all-cause prescriptions (with one exception) compared with those receiving a multi-pill combination. Conclusion: Direct CV-related costs were significantly lower in four out of seven comparisons, with a trend toward lower costs in the other three comparisons.

Abstract
Aims: Using German claims, the authors replicated the CHAARTED trial in metastatic hormone-sensitive prostate cancer. Methods: The authors identified metastatic hormone-sensitive prostate cancer patients replicating the inclusion/exclusion criteria of CHAARTED. Patients treated with docetaxel in combination with androgen deprivation therapy (ADT) at first line (docetaxel group) were compared with patients treated with ADT monotherapy (ADT mono group). After propensity score matching, overall survival was compared between the matched cohorts. Results: The authors included 441 patients. After propensity score matching, two equally sized matched cohorts of 74 patients each were compared in terms of overall survival. The hazard ratio (HR) was 0.71 (95% CI: 0.42-1.19), comparable to the HR in CHAARTED (HR: 0.72; 95% CI: 0.59-0.89). Conclusions: Using early comparative evidence from real-world data for regulatory and health technology assessment decisions is useful.

Abstract
Background Idiopathic pulmonary fibrosis (IPF) is a progressive form of fibrosing interstitial pneumonia with poor survival. This study provides insight into the epidemiology, cost, and disease course of IPF in Germany. Methods A cohort of incident patients with IPF (n = 1737) was identified from German claims data (2014–2019). Incidence and prevalence rates were calculated and adjusted for age differences compared with the overall German population. All-cause and IPF-related healthcare resource utilization as well as associated costs were evaluated per observed person-year (PY) following the initial IPF diagnosis. Finally, Kaplan–Meier analyses were performed to assess time from initial diagnosis to disease deterioration (using three proxy measures: non-elective hospitalization, IPF-related hospitalization, long-term oxygen therapy [LTOT]); antifibrotic therapy initiation; and all-cause death. Results The cumulative incidence of IPF was estimated at 10.7 per 100,000 individuals in 2016, 10.9 in 2017, 10.5 in 2018, and 9.6 in 2019. The point prevalence rates per 100,000 individuals for the respective years were 21.7, 23.5, 24.1, and 24.1. On average, ≥ 14 physician visits and nearly two hospitalizations per PY were observed after the initial IPF diagnosis. Of total all-cause direct costs (€15,721/PY), 55.7% (€8754/PY) were due to hospitalizations and 29.1% (€4572/PY) were due to medication. Medication accounted for 49.4% (€1470/PY) and hospitalizations for 34.8% (€1034/PY) of total IPF-related direct costs (€2973/PY). Within 2 years of the initial IPF diagnosis (23.6 months), 25% of patients died. Within 5 years of diagnosis, 53.1% of patients had initiated LTOT; only 11.6% were treated with antifibrotic agents. The median time from the initial diagnosis to the first non-elective hospitalization was 5.5 months. Conclusion The incidence and prevalence of IPF in Germany are at the higher end of the range reported in the literature. The main driver for all-cause cost was hospitalization. IPF-related costs were mainly driven by medication, with antifibrotic agents accounting for around one-third of the total medication costs even if not frequently prescribed. Most patients with IPF do not receive pharmacological treatment, highlighting the existing unmet medical need for effective and well-tolerated therapies.

Abstract
Aim Current guidelines for the treatment of arterial hypertension (AH) or cardiovascular (CV) prevention recommend combination drug treatments with single pill combinations (SPC) to improve adherence to treatment. We aimed to assess whether the SPC concept is clinically superior to multi pill combination (MPC) with identical drugs. Methods and Results In an explorative study, we analyzed anonymized claims data sets of patients treated with CV drugs for hypertension and/or CV disorders who were insured by the German AOK PLUS statutory health fund covering 01/07/2012-30/06/2018. Patients at age ≥18 years who received either a SPC or MPC with identical drugs were followed for up to one year. A one to one propensity score matching (PSM) was applied within patient groups who started identical drug combinations, and results were reported as incidence rate ratios (IRRs) as well as hazard ratios (HRs). After PSM, data from 59,336 patients were analyzed. In 30 out of 56 IRR analyses, superiority of SPC over MPC was shown. In 5 out of 7 comparisons, the HR for the composite outcome of all-cause death and all-cause hospitalizations was in favor of the SPC regimen (SPC versus MPC): valsartan/amlodipine: HR=0.87 (95% CI: 0.84–0.91, p ≤ 0.001); candesartan/amlodipine: 0.77 (95% CI: 0.65–0.90, p = 0.001); valsartan/amlodipine/hydrochlorothiazide: HR=0.68 (95% CI: 0.61–0.74, p ≤ 0.001); ramipril/amlodipine: HR=0.80 (95% CI: 0.77–0.83, p ≤ 0.001); acetylsalicylic acid (ASA)/atorvastatin/ramipril: HR=0.64 (95% CI: 0.47–0.88, p = 0.005). Conclusion SPC regimens are associated with a lower incidence of CV events and lower all-cause mortality in clinical practice. SPC regimens should generally be preferred to improve patient’s prognosis.

Abstract
Introduction Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune disease of the central nervous system which causes recurrent relapses, resulting in blindness, paralysis, and spinal cord damage. This study sought to explore the real-world burden, treatment, and cost of NMOSD in Germany using claims data. Methods Our study consisted of a retrospective analysis of two anonymized health insurance datasets covering around 9 million patients in Germany from 01/01/2013 to 31/12/2019. NMOSD patients were identified using inpatient and outpatient International Classification of Diseases, Tenth Revision (ICD-10) diagnoses of neuromyelitis optica (NMO; G36.0) and relevant symptom codes. Active periods of disease were identified based on relapse events (including hospitalizations and acute treatment); healthcare resource utilization (HCRU) and direct costs were allocated to active and inactive periods based on treatment dates. Propensity score matching was used to compare HCRU and cost outcomes among patients with and without NMOSD. Results Overall, 130 patients were identified as having NMOSD (mean age: 46.84 years; 58% female). NMOSD patients recorded 16.52 active and 348.48 inactive days per patient year (PPY). HCRU and associated costs were approximately tenfold higher during active periods than during inactive periods, with the largest share of the cost difference driven by hospitalizations (€6424.09/€259.10 per active/inactive month) and outpatient drug prescriptions (€412.83/€271.58). Direct healthcare costs incurred by patients with NMOSD (€12,913.28 PPY) were approximately threefold higher than those incurred by patients without NMOSD (€4667.66 PPY). Costs of hospitalization (€6448.32/€1937.64 PPY) and outpatient prescriptions (€3335.67/€1037.64 PPY) contributed most strongly to the difference. Conclusion Patients with NMOSD consume substantial healthcare resources and incur heavy costs during active disease phases. This study captured direct measurable healthcare costs and likely underestimates the real societal/emotional burden on patients and their families. Nevertheless, prevention of acute relapses represents one compelling strategy to minimize the economic burden of NMOSD in Germany.

Abstract
BACKGROUND There exists a range of treatments in the management of asthma. Non-adherence to these medications has been identified as a factor negatively impacting the effects of treatment. OBJECTIVE The objective of this study was to identify the potential barriers to medication adherence among adult patients with asthma in Germany. PATIENTS AND METHODS A multi-center observational study was conducted addressing adult patients with asthma who were prescribed regular maintenance medication between 2014 and 2016. Data were derived from physicians' documentation as well as claims data, which were linked to the above primary observational data, and patient survey data. Adherence barriers were assessed by the validated Adherence Barriers Questionnaire, both descriptively and in a logistic regression framework. Cluster analysis identified distinct patient groups with respect to the relevance of specific adherence barriers. RESULTS We included 524 patients with asthma (mean age 53.1 years, 74.6% female, 43.1% allergic asthma, 37.6% nonallergic, 19.3% mixed). Most of the participants reported to face at least three barriers (61.1%). Frequently reported barriers were the perception that medications are all harmful (53.6% of the participants), the burden of medication co-payment (44.1%), positive perception about current health status (39.9%), feeling of depression (30.9%), and the fear of side effects (27.5%). Four distinct patient clusters could be identified: cluster 1 with a low number of barriers (28.6% of participants), cluster 2 (11.6%) with a comparably high number of existing barriers, cluster 3 with high importance of depression as a barrier (27.3% of participants), and cluster 4 that was dominated by the perception that medications are all harmful (32.5% of participants). CONCLUSIONS Results of this study provide important insights for further development of adherence programs, which should focus on distinct patients' clusters that differ substantially in the relevance of specific adherence barriers.

Abstract
BACKGROUND This study analyzes the impact of skeletal-related events (SRE) on healthcare resource utilization (HCRU) and costs incurred by patients with bone metastases (BM) from solid tumors (ST), who are therapy-naïve to bone targeting agents (BTAs). METHODS German claims data from 01/01/2010 to 30/06/2018 were used to conduct a retrospective comparative cohort analysis of BTA-naive patients with a BM diagnosis and preceding ST diagnosis. HCRU and treatment-related costs were compared in two matched cohorts of patients with and without a history of SREs, defined as pathological fracture, spinal cord compression, surgery to bone and radiation to bone. The first SRE was defined as the patient-individual index date. Conversely, for the non-SRE patients, index dates were assigned randomly. RESULTS In total, 45.20% of 9,832 patients reported experiencing at least one SRE (n = 4444) while 54.80% experienced none (n = 5388); 2,434 pairs of SRE and non-SRE patients were finally matched (mean age: 70.87/71.07 years; females: 39.07%/38.58%). Between SRE and non-SRE cohorts, significant differences in the average number of hospitalization days per patient-year (35.80/30.80) and associated inpatient-care costs (14,199.27€/10,787.31€) were observed. The total cost ratio was 1.16 (p < 0.001) with an average cost breakdown of 23,689.54€ and 20,403.27€ per patient-year in SRE and non-SRE patients. CONCLUSION The underutilization of BTAs within a clinical setting poses an ongoing challenge in the real-world treatment of BM patients throughout Germany. Ultimately, the economic burden of treating SREs in patients with BM from ST was found to be considerable, resulting in higher direct healthcare costs and increased utilization of inpatient care facilities.

Abstract
OBJECTIVES Previous studies have shown that weekend hospitalizations are associated with poorer health outcomes and higher mortality ("weekend effect"). However, few of these studies have adjusted for disease severity and little is known about the effect on costs. This work investigates the weekend effect and its costs for patients with cerebral infarction in Germany, adjusting for patient characteristics and proxies of stroke severity. METHODS Adult patients with a cerebral infarction hospitalization 10th revision of the International statistical classification of diseases and related health problems (ICD-10: I63) between 01 January 2014 and 30 June 2017 were included from German health claims (AOK PLUS dataset). Propensity score matching was used to match patients hospitalized on weekends or on public holidays (weekend group) with patients hospitalized during the working week (workday group), based on baseline characteristics and proxies for disease severity such as concomitant diagnoses of aphasia, ataxia, and coma, or peg tube at index hospitalization. Matched cohorts were compared in terms of in-hospital, 7-day, and 30-day mortality, as well as risk and costs of stroke and rehabilitation stays in the year after first stroke. RESULTS Of 32,311 patients hospitalized with cerebral infarction between 01 January 2014 and 30 June 2017, 8409 were in the weekend group and 23,902 in the workday group. After propensity score matching, 16,730 patients were included in our study (8365 per group). Matched cohorts did not differ in baseline characteristics or stroke severity. In the weekend group, the risk of in-hospital death (11.2%) and the seven-day mortality rate (6.8%) were 13.1% and 17.2% higher than in the workday group, respectively (both p < 0.01). The hazard ratio for death in the weekend group was 1.1 (p = 0.043). The risks of subsequent stroke hospitalization and rehabilitation stays for a stroke were 8.4% higher and 5.5% higher in the weekend group (both p = 0.02). As a result, the stroke-related hospitalization and rehabilitation costs per patient year were, respectively, 5.6% and 8.0% higher in the weekend group (both p = 0.01). CONCLUSIONS A significant weekend effect emerged after controlling for observable patient characteristics and proxies of stroke severity. This effect also resulted in higher costs for patients admitted on weekends.

Abstract
OBJECTIVE The objective of this study was to assess non-adherence (NA) and non-persistence (NP) to long-acting asthma medications in Germany by differentiating between measurement of NA in periods of therapy continuation and measurement of NP in therapy-naïve patients. METHODS We analyzed treatment adherence to long-acting asthma medication using German claims data for periods of treatment continuation based on the medication possession ratio (MPR) and the proportion of days covered. Persistence was assessed in treatment-naïve patients. Outcomes were observed from the date of the first to the last prescription within a 12-month period. Both NA and NP analyses considered prescription supply, using either defined daily dosages, or prescribed daily dosages derived from a medical chart review. RESULTS We identified 52,508 asthma patients (mean age: 40.1, 58.4% female) who received at least two long-acting asthma prescriptions within 12 months; 50,660 treatment-naïve patients were included in the NP analysis (mean age: 39.7, 58.8% female). The mean 12-month MPR was 38.5% (89.4% NA according to MPR ≤ 80%) and the average proportion of days covered was 40.4% (85.9% NA). Agent-specific MPR and NA rates varied between 31.8% (91.8% NA) and 56.2% (71.6% NA). The average weighted-MPR increased to 53.1% when using the prescribed daily dosage. Based on a > 90-day gap definition, 86.7% of patients were considered non-persistent after 12 months (>180: 72.3%). When using prescribed daily dosages, NP rates ranged from 66.7 to 78.5%. CONCLUSION High levels of treatment NA and NP indicate a substantial need to improve adherence and persistence to long-acting asthma medication in Germany.

Abstract
BACKGROUND The objective of this study was to describe the real-world treatment and overall survival (OS) of German patients with a diagnosis of advanced non-small cell lung cancer (aNSCLC), and to explore factors associated with the real-world mortality risk. METHODS This was a retrospective German claims data analysis of incident aNSCLC patients. Data were available from 01/01/2011 until 31/12/2016. Identification of eligible patients took place between 01/01/2012-31/12/2015, to allow for at least 1-year pre-index and follow-up periods. Inpatient and outpatient mutation test procedures after aNSCLC diagnosis were observed. Further, prescribed treatments and OS since first (incident) aNSCLC diagnosis and start of respective treatment lines were described both for all patients and presumed EGFR/ALK/ROS-1-positive patients. Factors associated with OS were analyzed in multivariable Cox regression analysis. RESULTS Overall, 1741 aNSCLC patients were observed (mean age: 66·97 years, female: 29·87%). The mutation test rate within this population was 26·31% (n = 458), 26·6% of these patients (n = 122) received a targeted treatment and were assumed to have a positive EGFR/ALK/ROS-1 test result. Most often prescribed treatments were pemetrexed monotherapy as 1 L (21·23% for all and 11·11% for mutation-positive patients) and erlotinib monotherapy as 2 L (25·83%/38·54%). Median OS since incident diagnosis was 351 days in all and 571 days in mutation-positive patients. In a multivariable Cox regression analysis, higher age, a stage IV disease, a higher number of chronic drugs in the pre-index period and no systemic therapy increased the risk of early death since first aNSCLC diagnosis. On the other hand, female gender and treatment with therapies other than chemotherapy were associated with a lower risk of early death. CONCLUSIONS Despite the introduction of new treatments, the real-world survival prognosis for aNSCLC patients remains poor if measured based on an unselected real-world population of patients. Still, the majority of German aNSCLC patients do not receive a mutation test.

Abstract
Objective To compare the real-world effectiveness and safety of non-vitamin-K-antagonist oral anticoagulant (NOAC) treatment in atrial fibrillation (AF) patients with a vitamin-K-antagonist (VKA)-based treatment. Methods This was a retrospective analysis of an anonymized claims dataset from 3 German health insurance funds covering the period from January 01, 2010 to June 30, 2014, with a minimum observation time of 12 months. All continuously insured patients with at least 2 outpatient AF diagnoses and/or 1 inpatient respective diagnosis who received at least 1 outpatient prescription of a NOAC or VKA were included. Outcomes and measures Death, ischemic strokes (IS), non-specified strokes, transient ischemic attacks (TIAs), myocardial infarctions (MIs), arterial embolism (AE), hemorrhagic strokes, severe bleedings, and composite outcomes. Main comparisons were done based on propensity score-matched (PSM) cohorts. Results were reported as incidence rate ratios and hazard ratios (HRs). Results We assigned 37,439 AF patients to each PSM cohort (NOAC cohort: mean age 78.2 years, mean CHA2DS2VASc score 2.96, mean follow-up 348.5 days; VKA cohort: mean age 78.2 years, mean CHA2DS2VASc 2.95, mean follow-up 365.5 days). NOAC exposure was associated with significantly higher incidence rate ratios; 95% CI/HRs; 95% CI for the following outcomes: death (1.22; 1.17–1.28/1.22; 1.17–1.28), IS (1.90; 1.69–2.15/1.92; 1.69–2.19), non-specified strokes (2.04; 1.16–3.70/1.93; 1.13–3.32), TIAs (1.52; 1.29–1.79/1.44; 1.21–1.70), MIs (1.26; 1.10–1.15/1.31; 1.13–1.52), AE (1.75; 1.32–2.32/1.81; 1.36–2.34) and severe bleeding (1.92; 1.71–2.15/1.95; 1.74–2.20). Multivariable Cox regression analyses and additional sensitivity analysis, including analysis of PSM-matched NOAC/VKA treatment-naive patients, only confirmed the above results. The study was documented under clinicaltrials.gov (NCT02657616). Conclusion and relevance A VKA therapy seems to be more effective and safer than a NOAC therapy in a real-world cohort of German AF patients.

Abstract
SummaryAtrial fibrillation (AF) is the most common significant cardiac rhythm disorder. Oral anticoagulation (OAC) is recommended by guidelines in the presence of a moderate to high risk of stroke. Based on an analysis of claims-based data, the aim of this contribution is to quantify the stroke-risk dependent OAC utilisation profile of German AF patients as well as the possible causes and the associated clinical outcomes of OAC under-use. Our data set was derived from two large mandatory German medical insurance funds. Risk stratification of patients was based on the CHADS2-score and the CHA2DS2-VASc-score. Two different scenarios were constructed to deal with factors potentially disfavouring OAC use. Causes of OAC under-use and its clinical consequences were analysed using multivariate analysis. Observation year was 2008. A total of 183,448 AF patients met the inclusion criteria. This represents an AF prevalence of 2.21%. The average CHADS2-score was 2.8 (CHA2DS2-VASc-score: 4.3). On between 40.5 and 48.7% of the observed patient-days, there was no antithrombotic protection by OAC, other anticoagulants or aspirin. Older female patients with a high number of comorbidities had a higher risk of OAC under-use. Patients who had already experienced a thromboembolic event had a lower risk of OAC under-use. In the observation year, 3,367 patients experienced a stroke (incidence rate 1.8%). In our multi-level Poisson random effects estimate, OAC use decreases the stroke rate by almost 80% (IRR 0.236). In conclusion, OAC under-use is widespread in the German market. It is associated with severe clinical consequences.

Abstract
BACKGROUND This study assessed Staphylococcus aureus infection risk in patients with type 2 diabetes mellitus (T2DM) undergoing an orthopedic knee, hip, or spine surgery. PATIENTS AND METHODS All patients with a diagnosis of T2DM in the period from 2010 to 2012 were identified from a German claims database. First inpatient knee, hip, or spine surgery was used as index date. Cumulative incidence of S. aureus infections was calculated for several time intervals. Risk factors were identified based on a multi-variable Cox regression analysis. A case control analysis was conducted to assess mortality, healthcare resource utilization, and healthcare costs of S. aureus. RESULTS In total, 9,401 patients with T2DM underwent a knee, hip, or spine surgery. Mean age was 72.58 years, 63.32% were female, and 1.08% experienced an S. aureus infection in the 365-day follow-up period. The difference in all-cause direct treatment costs per patient-year between infected and non-infected patients was 24,437.50$. Mortality rates were 25.52% (S. aureus group) versus 5.22% (non-S. aureus group), based on a 365-day follow-up. CONCLUSIONS Staphylococcus aureus is associated with a substantial healthcare burden and high mortality. Effective infection control measures should be considered to reduce post-surgical S. aureus infection risk in patients with T2DM.

Abstract
PURPOSE The aim of this study was to describe persistence with vitamin K antagonist (VKA) treatment in German atrial fibrillation (AF) patients and to identify factors which may be associated with early discontinuation of VKA therapy. METHODS We did a retrospective cohort study based on an anonymized German claims dataset with VKA treatment-naïve AF patients, who received at least one VKA prescription. VKA therapy discontinuation was defined as a gap >180 days. RESULTS We identified 38,076 VKA patients who started a VKA therapy (mean age 76.13 years; 56.08% female; mean CHA2DS2-VASc-Score 4.49; mean Charlson Comorbidity Index (CCI) 3.91). After four quarters since start of VKA treatment, 14,889 (39.10%) of observed patients had discontinued their VKA treatment (after eight quarters: 54.61%). Mean time until treatment discontinuation was 390.55 days. Risk of VKA discontinuation increased with the diagnosis of dementia within the first two quarters of VKA treatment [HR 1.35 (95% CI 1.29-1.40)], diagnosed alcohol or drug abuse in the baseline period [HR 1.25; 95% CI 1.18-1.33)], female gender [HR 1.08; 95% CI 1.05-1.10)], higher age (HR 1.03; 95% CI 1.03-1.03), higher CCI (HR 1.05; 95% CI 1.04-1.05), any prescription of NSAID (HR 1.07; 95% CI 1.04-1.10), and number of surgeries in the first two quarters of VKA treatment (HR 1.05; 95% CI 1.04-1.05). At least one yearly visit to a cardiologist since start of VKA treatment decreased the risk of non-persistence [HR 0.90; 95% CI 0.88-0.93] and a cancer diagnosis in the baseline period (HR 0.92; 95% CI 0.89-0.96). CONCLUSION Non-persistence related to VKA therapy is common in AF patients. Older more comorbid female patients as well as patients who face surgeries and who do not visit a cardiologist regularly face a higher therapy discontinuation risk.

Abstract
OBJECTIVE This study aimed to assess the level of nonpersistence (NP) and nonadherence (NA) to methotrexate (MTX) therapy in German patients with rheumatoid arthritis (RA). MATERIALS AND METHODS Based on German claims data, RA patients who received a MTX therapy (subgroup: treatment-naive patients) were analyzed. NP was defined as treatment gap >12 weeks. Regarding NA, it is the overall medication possession ratio (MPR) during an observational period of 12 or 24 months after therapy, and the MPR is calculated only for the periods of therapy continuation; NA was defined as MPR <80%. RESULTS A total of 7,146 RA patients who received at least one MTX prescription (subgroup: 1,211 treatment-naive patients) could be observed (mean age: 64.4 years, 73.6% female). Percentage of NP patients among MTX-naive patients after 6, 12 and 18 months was 16.7%, 34.0% and 36.7%, respectively. After MTX therapy discontinuation, 39.9% had restarted their MTX therapy, 13.8% had received another non-MTX synthetic disease-modifying antirheumatic drug (sDMARD), 8.1% had biological DMARD (bDMARD) and 49.2% had not received any DMARD prescription at all. Overall, 12- and 24-month MPRs for MTX therapy were 83.0% and 76.5% with a percentage of NA patients of 25.8% and 33.8%, respectively. During periods of general treatment continuation, the percentage of patients with an MPR <80% was 6.5%. CONCLUSION NP to MTX treatment seems to be common in one-fourth of German patients with RA. An additional number of patients, at least 6.5%, are also affected by NA. A considerable percentage of RA patients who discontinued MTX therapy do not receive any follow-up DMARD therapy.

Abstract
BACKGROUND We compared all-cause mortality, major macrovascular events (MACE) and diabetes-related hospitalizations in T2DM-incident patients newly treated with metformin (MET) versus sulphonylureas (SU) monotherapy and in T2DM-prevalent patients newly treated with MET+SU versus MET+DPP4-inhibitor combination therapy. METHODS We analysed anonymized data obtained from a German health fund. Patients were included when they had started MET versus SU therapy or MET+SU versus MET+DPP4 therapy between 01/07/2010 and 31/12/2011. Observation started with the first MET/SU prescription or the first prescription of the second agent of a MET+SU/MET+DPP4 combination therapy. Follow-up time lasted until the end of data availability (a minimum of 12 months), death or therapy discontinuation. RESULTS In total, 434,291 T2DM-prevalent and 35,661 T2DM-incident patients were identified. Of the identified T2DM-incident patients, 904/7,874 started SU/MET monotherapy, respectively, with a mean age of 70.1/61.4 years (54.6/50.3 % female; Charlson Comorbidity Index (CCI) 1.4/2.2; 933/7,350 observed SU/MET patient years). 4,157/1,793 SU+MET/DPP4+MET therapy starters had a mean age of 68.1/62.2 years (53.4/50.8 % female; CCI 2.8/2.6; 4,556/1,752 observed SU+MET/ DPP4+MET patient years). In a propensity score matched (PSM) comparison, the HRs (95 % CIs) associated with SU monotherapy compared to MET monotherapy exposure were 1.4 (0.9-2.3) for mortality, 1.4 (0.9-2.2) for MACE, 4.1 (1.5-10.9) for T2DM hospitalizations and 1.6 (1.2-2.3) for composite event risk. In a multivariable Cox regression model, SU monotherapy was associated with higher mortality (aHR 2.0; 1.5-2.6), higher MACE (aHR 1.3; 1.0-1.7) and higher T2DM hospitalizations (aHR 2.8; 1.8-4.4), which corresponded with a higher composite event risk (aHR 1.8; 1.5-2.1). No significant differences in event rates were observed in the PSM comparison between DPP4+MET/SU+MET combination therapy starters and in the multivariable Cox regression analysis. CONCLUSIONS Our results show that SU monotherapy may be associated with increased mortality, MACE and T2DM hospitalizations, compared to MET monotherapy. When considering SU therapy, the associated cardiovascular risk should also be taken into account.

Abstract
OBJECTIVES We examined the real-world treatment of urinary tract infections (UTIs) in a type 2 diabetes mellitus (T2DM) population, evaluated UTI-related healthcare resource use and direct treatment costs, and assessed factors that may predict UTI-related costs. METHODS We analyzed an anonymized dataset from a regional German healthcare fund (2010-2012). UTI-associated resource use was described by the number of UTI-associated outpatient visits, the number and length of UTI-related acute hospital visits, and the number of UTI-related antibiotics prescriptions. UTI-related direct treatment costs were studied both based on these resource use numbers and, additionally, based on a comparison of all-cause annual healthcare costs of T2DM-patients who were or were not affected by a UTI. To identify factors that might predict direct treatment costs related to UTI treatment, we conducted generalized linear regression model analyses (based on gamma distribution) using sociodemographic and clinical characteristics of observed patients as available in the database as independent variables. RESULTS A total of 456,586 T2DM-patients were included with a mean age of 73.8, a percentage of 56.3 female patients, and a mean Charlson comorbidity index of 7.3. In our database, we observed 48,337 UTI events. The direct mean resource-based costs were €315.90 per UTI event. Older age, higher comorbidity status, at least one previous non-UTI infection, and poorer renal function were associated with higher costs, while female gender and at least one previous UTI event were associated with lower costs. In the all-cause cost analysis, healthcare costs per patient year were €3,916 higher in the UTI group than in the non-UTI group. CONCLUSION Our study confirms that UTI is a common complication in patients with T2DM. Patients with T2DM who have had previous infections, who are older, and who are male, as well as patients who have more comorbidities or severe renal insufficiency, face above-average UTI treatment costs. These patient groups, therefore, should receive special attention in the real-world treatment of T2DM, which should include a regular screening of UTI risk.

Abstract
INTRODUCTION Our main aim was to assess the level of persistence and adherence to therapy with glucagon-like peptide-1 (GLP-1) receptor agonists in type 2 diabetes mellitus (T2DM) patients in the United Kingdom (UK) and Germany, also by comparing once- (OD) with twice-a-day (BID) therapy. METHODS We used two large retrospective datasets: a German claims dataset and the UK General Practitioner (GP)-based Clinical Practice Research Datalink (CPRD) dataset (2010-2012). All continuously insured T2DM patients with at least one outpatient/inpatient T2DM diagnosis were observed starting with the first prescription of a GLP-1 receptor agonist. Non-persistence (NP) was defined as treatment gap >90 days. Non-adherence (NA) was defined as medication possession ratio <80%, calculated during a period in which a patient continued therapy (no treatment gap >90 days) only. RESULTS In the UK sample, 1905 T2DM patients started a treatment with GLP-1 receptor agonists (mean age: 55.5 years, 47.2% female). In the German sample, 1627 T2DM patients started a treatment with GLP-1 receptor agonists (mean age: 56.6 years, 51.4% female). Percentage of NP patients after 12 months was 29.5% in the UK and 36.4% in the German sample. In both countries, a BID treatment was associated with a higher probability to discontinue a treatment with GLP-1 receptor agonists earlier than an OD treatment (hazard ratio [HR] = 1.431 in UK and HR = 1.314 in Germany). The percentages of patients considered NA were 20.2%/20.0%/20.5% (all/OD/BID) for the UK sample, and 19.9%/19.2%/21.8% (all/OD/BID) for the German sample. CONCLUSION NP and NA to treatment with GLP-1 receptor agonists in both UK and Germany appear to be similar. Persistence to OD treatment is higher than to BID treatment in both the UK and Germany.

Abstract
INTRODUCTION This analysis was conducted to investigate urinary tract infection (UTI) incidence among Type 2 Diabetes mellitus (T2DM) patients in Germany in a real-world setting and to identify risk factors associated with UTI incidence/recurrence. METHODS Our cohort study was conducted based on an anonymized dataset from a regional German sickness fund (2010-2012). A UTI event was mainly identified through observed outpatient/inpatient UTI diagnoses. We reported the number of UTI events per 1000 patient-years. Furthermore, the proportion of patients affected by ≥1 and ≥2 UTI events in the observational period was separately reported. Finally, three multivariate Cox regression analyses were conducted to identify factors that may be associated with UTI event risk or recurrent UTI event risk. RESULTS A total of 456,586 T2DM-prevalent patients were identified (mean age 72.8years, 56.1% female, mean Charlson Comorbidity Index (CCI) of 7.3). Overall, the UTI event rate was 87.3 events per 1000 patient-years (111.8/55.8 per 1000 patient-years for women/men (p<0.001)). The highest UTI event rates were observed for those aged >89years. After 730days after first observed T2DM diagnosis, the proportion of women/men still UTI-event-free was 80.9%/90.2% (p<0.001). Most important factors associated with UTI risk in our three models were older age (Hazard Ratio (HR)=1.56-1.70 for >79years), female gender (HR=1.38-1.57), UTIs in the previous two years (HR=2.77-5.94), number of comorbidities as measured by the CCI (HR=1.32-1.52 for CCI>6) and at least one cystoscopy in the previous year (HR=2.06-5.48). Furthermore, high HbA1c values in the previous year (HR=1.29-1.4 referring to HbA1c>9.5%) and a poor kidney function (HR=1.11-1.211 referring to glomerular filtration rate (GFR)<60ml/min) increased the UTI event risk. DISCUSSION Our study confirms that UTI event risk is high in T2DM patients. Older female patients having experienced previous UTIs face an above-average UTI risk, especially if these risk factors are associated with poor glycemic control and poor kidney function.

Abstract
BACKGROUND The aim of this study was to analyse which factors predict the real-world macro-/microvascular event, hospitalisation and death risk in patients with type 2 diabetes mellitus. Furthermore, we aimed to investigate whether there exists both an under- and over-treatment risk of these patients. METHODS We used a German claims/clinical data set covering the years 2010-12. Diabetes-related events were defined as (1) macro-, (2) microvascular events leading to inpatient hospitalisation, (3) other hospitalisations with type 2 diabetes mellitus as main diagnosis, (4) all-cause death and (5) a composite outcome including all event categories 1-4. Factors associated with event risk were analysed by a Kaplan-Meier curve analysis and by multivariable Cox regression models. RESULTS 229,042 patients with type 2 diabetes mellitus (mean age 70.2 years; mean CCI 6.03) were included. Among factors that increased the event risk were patients' age, male gender, the adapted Charlson Comorbidity Index, the adapted Diabetes Complication Severity Index, previous events, and number of prescribed chronic medications. For systolic blood pressure/HbA1C, a double-J/U-curve pattern was detected: HbA1C of 6-6.5% (42-48 mmol/mol) and systolic blood pressure of 130-140 mmHg (17.3-18.7kPa) were associated with the lowest event risk, values below/above that range were associated with higher risk. However, this pattern was mainly driven by the death risk and was much less clearly observed for the macrovascular/microvascular/hospitalization risk and for young/less comorbid patients. CONCLUSIONS Both blood pressure and HbA1C seem to be very important treatment targets, especially in comorbid old patients. It is of particular clinical importance that both over- and under-treatment pose a threat to patients with type 2 diabetes mellitus.

Abstract
OBJECTIVES The aim of this claims-based data analysis was to describe the care of German T2DM patients and to determine which subgroups could be differentiated in terms of the achieved T2DM-related treatment results, the underlying comorbidities, and the achieved comorbidity-related treatment results. METHODS We included all T2DM patients insured by a large sickness fund in 2010/2011. We defined 12 subgroups according to observed HbA1C, blood pressure and Charlson Comorbidity Index (CCI). For each subgroup, available sociodemographic and clinical information were reported. Different treatment variables were described. T2DM-related events leading to acute hospitalisations were reported. RESULTS We included 394,828 T2DM patients in our analysis; for 228,703 patients' detailed data as basis for subgroup classification were available. For 4.5% of these patients, a HbA1C >9% was observed. 21,833 of the T2DM patients were affected by a T2DM-related event; the risk was 5.53% per patient year; 1.74% of the patients suffered from more than one event. Most frequent event types were hospitalisation with T2DM as primary diagnosis (2.39%), vascular interventions/stent implantations (1.92%), and ischaemic stroke (1.19%). There were significant differences between the observed subgroups in terms of T2DM-related event risk. CONCLUSION Overall, our data indicate that the typically treated T2DM patient has a number of comorbidities and thus treatment focused solely on T2DM is neither possible nor clinically meaningful. Particularly those patients who reached HbA1C goals, but had also achieved relevant additional treatment goals reached low yearly T2DM event rates whereas subgroups failing to achieve one or several treatment goals are facing much higher event risks.

Abstract
BACKGROUND The aims of this study were to evaluate the quality of oral anticoagulation (OAC) in AF patients in the practices of general practitioners (GPs) in Germany and to investigate possible causal factors which influence OAC quality. METHODS We conducted a multi-center, non-interventional, prospective observational cohort study among general practitioners (GPs) in Germany. To assess the quality of OAC on the basis of the prospectively documented international normalized ratio (INR) values, the time in therapeutic range (TTR) was calculated using the Rosendaal linear trend method. The causes of poor OAC quality were identified by a multivariate analysis model (logistical regression; poor OAC quality: TTR <60%). RESULTS AND CONCLUSIONS For 525 OAC patients (66.8%; patients with at least 2 prospectively documented INR values) the average TTR (target range of 2.0-3.0) was 67.6%. About 34.7% of the patients had a TTR <60%. None of the variables representing characteristics of the medical practices were capable of explaining the occurrence of poor OAC quality. However, with regard to care provision-based variables, the existence of a brief discontinuation of medication was important. As the existence of adherence barriers increased, the probability of poor anticoagulation quality increased. In conclusion, the provision of OAC in the German health care system is to be regarded as good, but far from ideal. Our causal analysis shows that patient-based factors should be addressed through the provision of improved training and that the rationale behind the interruption of OAC treatment should be critically examined.
