Epidemiology, real-world treatment and mortality of patients with status epilepticus in Germany: insights from a large healthcare database.

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.

Real-world systemic treatment of patients with psoriasis: A retrospective study based on German claims data.

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.

Improved Persistence to Medication, Decreased Cardiovascular Events and Reduced All-Cause Mortality in Hypertensive Patients With Use of Single-Pill Combinations: Results From the START-Study.

BACKGROUND: Single-pill combination improves adherence and persistence to medication in hypertension. It remains unclear whether this also reduces cardiovascular outcomes and all-cause mortality. We analyzed whether single-pill combinations are superior to identical multiple pills on persistence to medication, cardiovascular outcomes, and all-cause mortality. METHODS: This was a retrospective claims data (German AOK PLUS) analysis. Data from hypertensive patients ≥18 years treated with renin-angiotensin system combinations given as single pill or identical multipills covering the years 2012 to 2018 were analyzed and followed up to at least 1 year. After 1:1 propensity score matching, persistence to medication, cardiovascular events, and all-cause mortality were compared using non-parametric tests. Results were reported as incidence rate ratios and hazard ratios. RESULTS: After propensity score matching data from 57 998 patients were analyzed: 10 801 patients received valsartan/amlodipine, 1026 candesartan/amlodipine, 15 349 ramipril/amlodipine, and 1823 amlodipine/valsartan/hydrochlorothiazide as single pill or identical multipill. No relevant differences in patient characteristics were observed within the 4 groups. In all groups, a significant lower all-cause mortality, a significant a higher persistence to medication, a significant lower event rate in 15 out of 20 comparisons, and a tendency in the remaining 5 comparisons was observed under single pills compared with multipill combinations. CONCLUSIONS: Antihypertensive combination therapy reduces all-cause mortality and cardiovascular events when provided as single pill compared to identical drugs as multipills. This strongly supports the European Society of Cardiology/European Society of Hypertension and International Society of Hypertension guidelines recommending the use of a single-pill combination and thus should be more rigorously implemented into daily clinical practice.

Epidemiology and treatment of myasthenia gravis: a retrospective study using a large insurance claims dataset in Germany.

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.

Real-world treatment of German patients with recurrent and advanced endometrial cancer with a post-platinum treatment: a retrospective claims data analysis.

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.

Persistence with Biologic Treatment in Patients with Inflammatory Bowel Disease: A German Claims Data Analysis.

OBJECTIVES: This study aimed to assess the real-world rates of treatment discontinuation and switching of biologic therapies in patients with inflammatory bowel disease (IBD). METHODS: A retrospective claims data analysis on all continuously insured adult IBD patients with initiation of a biologic therapy was conducted. Observation started with the date of the first prescription of index tumor necrosis factor α-inhibitors (anti-TNFα) or vedolizumab (VDZ) therapy and lasted 12 months. Non-persistence was assumed in case of a switch to another biologic or a treatment gap of >90 days. RESULTS: We included 1,248 IBD biologic treatment starters (502 adalimumab, 77 golimumab, 441 infliximab, 228 VDZ); 837/411 were biologic-naïve (bio-naïve)/ biologic-experienced (bio-experienced). Mean age of bio-naïve/bio-experienced anti-TNFα patients was 39.2/38.1 years (54.9%/56.7% female) and 42.6/37.8 years for VDZ patients (56.3%/54.9% female). Seven hundred and seventy-two patients (61.9%) were persistent with their index biologic therapy after 12 months (61.9%/61.8% bio-naïve/bio-experienced). Percentage of persistent patients was 69.7% for VDZ (65.6%/71.3%) and 60.1% for anti-TNFα (61.4%/55.5%). VDZ was associated with later non-persistence in a multivariable Cox regression analysis (hazard ratio 0.675; p = 0.003) compared to anti-TNFα. CONCLUSIONS: Only 60-70% of IBD -patients are still persistent with their biologic therapy after 12 months. VDZ therapy is associated with a higher persistence than anti-TNFα therapy in this analysis.

Real-world treatment and fracture incidence in postmenopausal women with severe osteoporosis at high risk of fracture: a retrospective claims data analysis.

Background: Osteoporosis (OP) and its associated fractures have a significant impact on patients' quality of life and are impacting their morbidity and mortality. For OP patients at high risk of fracture, guidelines recommend a pharmacological OP treatment. The aim of this study was to describe the real-world medication treatment of postmenopausal women with severe OP at high risk of fracture, their risk to experience a new fracture after having at least one previous fracture, and to assess the associated healthcare resource use (HCRU). Methods: This retrospective cohort study was based on anonymized German claims data (AOK PLUS). All included OP patients were female, ≥55 years old, and had a vertebral and/or femoral fracture. We conducted a cross-sectional analysis in 2018 and a longitudinal analysis, starting with an incident vertebral/femoral fracture (after or simultaneously with the first observed OP diagnosis). In both analyses, patient characteristics, rate of new incident fractures, OP treatment patterns, and HCRU associated with the treatment of patients were investigated. Results: In the cross-sectional setting, 12,180 patients with a mean age of 83.59 years were observed. Of these patients, 14.30% sustained at least one new incident fracture and 34.54% received a pharmaceutical OP treatment during 2018. In this year, 58.50% of the patients had at least one OP-related outpatient visit, and 26.35% had a fracture-related visit. In 160 patients (1.31%), at least one OP-related hospitalization was documented, and in 1,293 patients (10.62%) a fracture-related hospitalization in 2018. In the longitudinal setting, 10,323 patients with a mean age of 83.22 years were included. Of these, 18.96% experienced at least one new incident fracture within the first 12 months after the index fracture, and in total 30.85% in the entire follow-up period (mean 2.03 years). During the 12-month baseline period, 22.12% of the patients received an OP treatment. Three months after the index fracture, the proportion of treated patients remained at 22.30%. During the total follow-up time, 35.54% were prescribed with an OP treatment. Conclusion: We observed a considerable proportion of untreated patients and a high rate of subsequent fractures. The awareness for a proper risk assessment and the appropriate use of available treatments should be increased.
