Importance: A growing body of literature suggests the presence of a prodromal period with nonspecific signs and symptoms before onset of multiple sclerosis (MS).

Objective: To systematically assess diseases and symptoms diagnosed in the 5 years before a first MS- or central nervous system (CNS) demyelinating disease-related diagnostic code in pediatric patients compared with controls without MS and controls with another immune-mediated disorder, juvenile idiopathic arthritis (JIA).

Design, Setting, And Participants: This population-based, matched case-control study included children and adolescents (aged <18 years) in Germany with statutory health insurance from January 2010 to December 2020.

Background: The epidemiological characterization of endometri - osis, particularly with regard to its incidence, has been inadequate to date both in Germany and other countries. The goal of this study was to determine trends in the incidence of diagnosed endometri - osis and changes in age structure at the time of first diagnosis over the period 2014-2022.

Methods: Nationwide claims data from physicians in private practice, obtained according to relevant German law (§ 295 SGB V), were used to identify the population at risk for a first assured diagnosis of endometriosis (ICD-10-GM: N80) during each year of the study period, consisting of women and girls aged 10-52 who were insured by the statutory health insurance system and for whom at least two years of prior observation were possible.

Introduction: Research linking type 2 diabetes and depression mostly relied on hospital-based diagnoses or prescription data, overlooking many outpatient diagnoses. We aimed to quantify the risks of depression in individuals newly diagnosed with type 2 diabetes, and type 2 diabetes in those newly diagnosed with depression, while exploring potential risk differences depending on age, sex, and follow-up time.

Research Design And Methods: We conducted a matched cohort study using German nationwide outpatient claims data from 2012 to 2022.

Background And Purpose: Idiopathic Parkinson's disease (IPD) is a progressive neurodegenerative disorder that is strongly associated with age. The aim of the present study was to describe current sex- and age-specific trends and regional differences in the incidence of IPD diagnosed in older people in Germany.

Methods: This study was based on nationwide outpatient claims and drug prescription data from the German Statutory Health Insurance, covering approximately 87% of the general population.

Background: This claims-based study aimed to assess recent nationwide trends in pediatric incidence of atopic diseases in Germany.

Methods: Incidence of atopic dermatitis, asthma, and hay fever was assessed from 2013 to 2021 in annual cohorts of 0- to 17-year-old children and adolescents with statutory health insurance (N = 11,828,525 in 2021).

Results: Incidence of atopic dermatitis remained largely unchanged (15.

Background: Venous thromboembolism (VTE) and arterial thromboembolism (ATE) are considered as two separate disease-entities. In recent years, studies have reported clear associations between VTE and atherosclerosis. We aimed to evaluate the long-term risk of ATE in VTE patients in comparison to controls without VTE.

The aim of the study was to examine whether the COVID-19 pandemic had any effect on antibiotic prescription rates in children in Germany. Using the nationwide outpatient prescription data from the Statutory Health Insurance from 2010 to 2021, changes in the monthly prescriptions of systemic antibiotics dispensed to children aged 0-14 years were examined ( = 9,688,483 in 2021). Interrupted time series analysis was used to assess the effect of mitigation measures against SARS-COV-2, introduced in March and November 2020, on antibiotic prescription rates.

Purpose: We aimed to examine possible variations in diagnostic prevalence of hay fever between urban and rural regions as well as in age-specific temporal developments.

Patients And Methods: We used nationwide outpatient claims data from the years 2010 to 2019. The data contain information for all individuals with statutory health insurance (SHI) in Germany who were treated at least once in respective years (n = 71,410,121 in 2019).

Article Synopsis
  • A study calculated the total number of Lyme borreliosis (LB) cases in Germany for 2019, revealing there were 128,177 diagnosed cases, resulting in an incidence rate of 179 per 100,000 insured individuals.
  • There were significant regional variations in incidence rates, with some districts reporting rates as high as 646 per 100,000, particularly in areas with more forests and agricultural land.
  • The research highlighted considerable under-reporting, showing a discrepancy between claimed cases and official reports, suggesting the need for targeted public health interventions.

Background: This study aimed to describe recent developments of multiple sclerosis (MS) prevalence in Germany and to assess utilization patterns of disease-modifying drugs (DMDs).

Methods: We used nationwide outpatient claims data of the statutory health insurance (SHI) from the years 2012 to 2019, covering 87% of the total German population. In annual cross-sectional analyses, MS prevalence was measured as the percentage of the SHI population affected by MS.

Background: Research has shown that the risk for a severe course of COVID-19 is increased in the elderly population and among patients with chronic conditions. The aim of this study was to provide estimates of the size of vulnerable populations at high risk for a severe COVID-19 course in Germany based on the currently available risk factor data.

Methods: We used nationwide outpatient claims data from the years 2010 to 2019 collected according to § 295 of the Code of Social Law V, covering data for all statutory health insurees (SHI) which is nearly 87% of the entire German population.
