1. Support by telestroke networks is associated with increased intravenous thrombolysis and reduced hospital transfers : A german claims data analysis
abstractBackground Acute stroke treatment is time-critical. To provide qualified stroke care in areas without 24/7 availability of a stroke neurologist, the concept of teleneurology was established, which is based on remote video communication through telemedicine organized by telestroke networks. Data on the effectiveness and efficiency of stroke treat- ment via teleneurology is very scarce and is therefore partly questioned in the healthcare sector. The aim was to evaluate stroke care in hospitals with and without teleneurology in Northern Germany. Methods We conducted a retrospective case-control data analysis using health insurance claims data for the years 2018 to 2021. Based on pre-defined criteria, two models were defined and clinical as well as health economic param- eters were compared. In model 1, we compared patients from hospitals with and without support by a telestroke network, while in model 2, we compared patients from hospitals with and without support by a telestroke network, including only districts without a certified stroke unit. Assessed parameters were age, length of stay, patients' comorbidities, inpatient costs, reasons for discharge, qualified stroke care treatment according to operation and procedure codes (OPS) and intravenous thrombolysis (IVT) rates. Results Hospitals supported by a telestroke network improved their rate of stroke care according to OPS and increased more than three-fold their IVT rate (p = 0.042). In comparison, patients from hospitals with support by a telestroke network had a higher number and rate of qualified stroke care according to OPS (model 1: 73.6% vs 2.2%, p < 0.001 and model 2: 57.0% vs 3.8%, p < 0.001), higher rate of IVT (model 1: 9.5% vs. 0.0%, p = 0.027 and model 2: 10.3% vs 0.0%, p = 0.056) and a lower rate of secondary transfers to another hospital (model 1: 5.9% vs. 28.9%, p < 0.001 and model 2: 5.6% vs 30.1%, p < 0.001). Inpatient costs were lower in cases treated in hospitals with support by a telestroke network (model 1: 4,476€ vs. 5,549€, p = 0.03 and model 2: 4,374€ vs. 5,309€, p = 0.02). In multivariate analysis costs were independently associated with length of stay and patient transfer to another hospital but not with support by a telestroke network. Conclusion Hospitals with support by a telestroke network are associated with improved qualified stroke care resulting in higher rates of IVT and stroke care according to OPS codes as well as lower rates of onward transfers. Costs per patient were independently associated with transfer rates and length of hospital stay.

5. Regional differences in health care of patients with inflammatory bowel disease in Germany
abstractBackground: The regional availability of specialized physicians is an important aspect in healthcare of patients with IBD. The association between physician density and healthcare is not yet clear. Most studies did not consider district type, which reflects population density. Our research question was, "Do specialist density and district type influence the healthcare of IBD patients in Germany?" Methods: We combined a claims dataset from a German health insurance fund with population and physician data. Four main aspects were investigated: regular specialist visits, drug therapies, surveillance colonoscopy, and IBD-related hospitalizations. Various regression analyses were performed. Results: The study cohort was comprised of 21,771 individuals, including 9282 patients with Crohn disease and 12,489 patients with ulcerative colitis. Patients who were living in districts with higher specialist densities were more likely to attend specialist visits on a regular basis. No difference in the frequencies of TNF-alpha inhibitor therapies was found. However, individuals from urban areas were more likely to receive a permanent immunosuppressive therapy with continuous specialist support. Conclusions: The results revealed that some aspects had positive effects on the probability of implementing healthcare in accordance with pathways and guidelines. No clear evidence of a general healthcare undersupply in rural areas was found.

6. Costs and treatment patterns of incident ADHD patients : a comparative analysis before and after the initial diagnosis
abstractBackground and objectives: The costs and treatment patterns of attention deficit hyperactivity disorder (ADHD) are subjects of health services research in Germany and worldwide. Previous publications focused mainly on prevalent patients and thus research gaps were identified regarding costs and treatment patterns of incident patients before and after the first diagnosis. Methods: Analyses were conducted using claims data obtained from a large German sickness fund (Techniker Krankenkasse). Inclusion criteria consisted of patients with at least two secured outpatient or one inpatient ADHD diagnosis in 2007. Incidence was ensured by defining a baseline period without ADHD-diagnosis in 2006. In addition to diseaserelated cost analyses compared to a control group including age group comparisons, comorbidities, the proportion of multimodal treatment and medication treatment patterns were described. Results: In total, 9083 newly diagnosed ADHD patients were identified (73 % male; mean age: 12.9 years (SD: 10.3)). The mean total cost of ADHD patients during the year after the first diagnosis exceeded the mean total cost of the year before by 976 € Differencein-Difference-estimator: 1006 €). Our analyses have shown that 10 % of ADHD patients have been treated with multimodal therapy. In addition, 11 % of the investigated ADHD population have received methylphenidate or atomoxetine preceeding the date of diagnosis in the relevant observation period. Discussion: This study provides important insights into the costs as well as the treatment patterns of incident ADHD patients. ADHD-related costs and medications can be identified prior to the date of the first ADHD diagnosis. Although, multimodal therapy is presented as an optimal treatment option by many international guidelines and experts, its proportion for treatment is low (10 %). Further research is necessary to identify reasons for the low proportion of multimodal therapy and (cost-)effectiveness has to be evaluated in comparison to other treatment options. In addition, ADHD-related costs could be identified before the first diagnosis is documented. The reasons for medication prior to diagnosis have to be further investigated.

8. Biologic TNF inhibiting agents for treatment of rheumatoid arthritis : persistence and dosing patterns in Germany
abstractObjective: To obtain detailed real-world data on persistence and dosing patterns in the utilisation of the TNF inhibitors adalimumab, etanercept, and infliximab in rheumatoid arthritis (RA) patients treated in Germany. Methods: In this retrospective observational study claims data of a major German health insurance fund between 2005 and 2008 were analysed. Patients receiving at least one prescription of adalimumab, etanercept or infliximab were identified and categorised as "TNF inhibitor naive" or "TNF inhibitor continuing". For the calculation of TNF inhibitor persistence a survival analysis with the Kaplan-Meier estimator was used. A Cox regression was used to analyse, if any relevant factors were influencing persistence. Dosage increase rates were analysed for adalimumab, etanercept and infliximab. Sensitivity analyses based on variations in gap length were conducted. Results: A total of 2,201 RA patients were identified. 1,468 of these patients were TNF inhibitor naive patients and 733 were defined as TNF inhibitor continuing patients. There were no significant differences in the treatment persistence rates between adalimumab, etanercept and infliximab for TNF inhibitor naive and continuing patients. The persistence rate after three years was 22.47% for adalimumab, 24.27% for etanercept and 21.49% for infliximab naive patients. For continuing patients, the persistence rate after three years was 32.88% for adalimumab, 30.95% for etanercept, and 33.90% for infliximab, respectively. Gender, medication and Charlson Comorbidities Index did not influence the persistence significantly. Dosage increase occurred in 7.3% adalimumab, 1.4% etanercept, and 17.2% infliximab naive patients and 5.8%, 1.1% and 11.9% respectively in the continuing patients. Conclusions: In this study, there were no significant differences in persistence among adalimumab, etanercept and infliximab treated patients. Consistent with previous research, there was a higher dose escalation for infliximab than for the two subcutaneous treatments, adalimumab or etanercept.
