RESUMO
Background: To date, there is no data available depicting the trend of the incidence of type 1 and type 2 diabetes across all age groups for the COVID-19 pandemic years in Germany. Methods: Based on anonymized routine data from nine million persons covered by statutory health insurance, newly diagnosed diabetes cases (ICD diagnosis E10.- to E14.-) in inpatient or (confirmed in two quarters) outpatient setting were estimated for 2015 to 2021, differentiating between type 1 and type 2 diabetes. The data were linked to the German Index of Socioeconomic Deprivation. The results are age-standardised (population as of 31 Dec. 2021). Results: Between 2015 and 2021, the incidence of type 1 diabetes increased from 9.5 to 11.6 per 100,000 persons (from 7,007 to 8,699 new cases per year). In contrast, the incidence of type 2 diabetes tended to decline between 2015 and 2019. It continued to drop initially in 2020 during the pandemic, and then rose to 740 per 100,000 persons in 2021 (556,318 new cases per year). The diabetes type-specific seasonal pattern of previous years has changed during the pandemic years. The incidence of both type 1 and type 2 diabetes was observed to be higher in regions of high socioeconomic deprivation as compared to regions characterised by low socioeconomic deprivation. Conclusions: The increase in the incidence of type 1 and type 2 diabetes in 2021 may possibly be related to the COVID-19 pandemic. The high incidence and the differences by regional socioeconomic deprivation indicate that there is a need for targeted prevention strategies.
RESUMO
INTRODUCTION: During the COVID-19 pandemic, occupation was assumed to play a central role in the occurrence of infection and disease. For Germany, however, there are only a few studies that analyse occupational differences in risk of COVID-19, COVID-19-associated hospitalisation, and mortality. METHODS: The study uses longitudinal health insurance data from the research database of the Institute for Applied Health Research (InGef) with information on 3.17 million insured persons aged 18-67 years (1,488,452 women; 1,684,705 men). Outcomes (morbidity, hospitalisation, and mortality) were determined on the basis of submitted COVID-19 diagnoses between 1 January 2020 and 31 December 2021. Occupations were classified according to four groupings of the official German classification of occupations. In addition to cumulative incidences, relative risks (RR) were calculated - separately for men and women. RESULTS: There is an increased risk of disease in personal service occupations, especially in health care, compared to other occupations (RR for women 1.46; for men 1.30). The same applies to social and cultural service occupations (but only for women) and for manufacturing occupations (only for men). In addition, the risks for hospitalisation and mortality are increased for cleaning occupations and transport and logistics occupations (especially for men). For all three outcomes, the risks are higher in non-managerial occupations and differ by skill level (highest for unskilled jobs and lowest for expert positions). CONCLUSION: The study provides important findings on work- and gender-related differences in COVID-19 morbidity and mortality in Germany, which indicate starting points for structural infection protection measures.

Aim: We aimed to develop a risk score to calculate a person's individual risk for a severe COVID-19 course (POINTED score) to support prioritization of especially vulnerable patients for a (booster) vaccination. Subject and methods: This cohort study was based on German claims data and included 623,363 individuals with a COVID-19 diagnosis in 2020. The outcome was COVID-19 related treatment in an intensive care unit, mechanical ventilation, or death after a COVID-19 infection. Data were split into a training and a test sample. Poisson regression models with robust standard errors including 35 predefined risk factors were calculated. Coefficients were rescaled with a min-max normalization to derive numeric score values between 0 and 20 for each risk factor. The scores' discriminatory ability was evaluated by calculating the area under the curve (AUC). Results: Besides age, down syndrome and hematologic cancer with therapy, immunosuppressive therapy, and other neurological conditions were the risk factors with the highest risk for a severe COVID-19 course. The AUC of the POINTED score was 0.889, indicating very good predictive validity. Conclusion: The POINTED score is a valid tool to calculate a person's risk for a severe COVID-19 course.

RESUMO
OBJECTIVES: To investigate whether the risk of developing an incident autoimmune disease is increased in patients with prior COVID-19 disease compared to those without COVID-19, a large cohort study was conducted. METHOD: A cohort was selected from German routine health care data. Based on documented diagnoses, we identified individuals with polymerase chain reaction (PCR)-confirmed COVID-19 through December 31, 2020. Patients were matched 1:3 to control patients without COVID-19. Both groups were followed up until June 30, 2021. We used the four quarters preceding the index date until the end of follow-up to analyze the onset of autoimmune diseases during the post-acute period. Incidence rates (IR) per 1000 person-years were calculated for each outcome and patient group. Poisson models were deployed to estimate the incidence rate ratios (IRRs) of developing an autoimmune disease conditional on a preceding diagnosis of COVID-19. RESULTS: In total, 641,704 patients with COVID-19 were included. Comparing the incidence rates in the COVID-19 (IR=15.05, 95% CI: 14.69-15.42) and matched control groups (IR=10.55, 95% CI: 10.25-10.86), we found a 42.63% higher likelihood of acquiring autoimmunity for patients who had suffered from COVID-19. This estimate was similar for common autoimmune diseases, such as Hashimoto thyroiditis, rheumatoid arthritis, or Sjögren syndrome. The highest IRR was observed for autoimmune diseases of the vasculitis group. Patients with a more severe course of COVID-19 were at a greater risk for incident autoimmune disease. CONCLUSIONS: SARS-CoV-2 infection is associated with an increased risk of developing new-onset autoimmune diseases after the acute phase of infection. Key Points ⢠In the 3 to 15 months after acute infection, patients who had suffered from COVID-19 had a 43% (95% CI: 37-48%) higher likelihood of developing a first-onset autoimmune disease, meaning an absolute increase in incidence of 4.50 per 1000 person-years over the control group. ⢠COVID-19 showed the strongest association with vascular autoimmune diseases.

For appropriate response to the COVID-19 pandemic, and for obtaining answers to various relevant research questions, empirical data are required. Claims data of health insurances are a valid data source in such a situation. Within the project egePan-Unimed of the Netzwerk Universitätsmedizin (NUM) we investigated five COVID-19-related research questions using German claims data of statutory health insurances. We studied the prevalence and relevance of risk factors for a severe course of COVID-19, the background incidence of cerebral venous sinus thrombosis and myocarditis, the frequency and symptoms of post-COVID as well as the care of people with a psychiatric condition during the COVID-19 pandemic. Based on these cases, context-specific recommendations regarding the use of German claims data for future pandemics or other public health emergencies were derived, namely that the utilization of established and interdisciplinary project teams enables a timely project start and furthermore, meta-analytic methods are a valuable way to pool aggregated results of claims data analyses when data protection regulations do not allow a consolidation of data sets from different statutory health insurances. Under these circumstances, claims data are a readily available and valid data source of empirical evidence base necessary for public health measures during a pandemic.

BACKGROUND: Long-term health sequelae of the Coronavirus Disease 2019 (COVID-19) are a major public health concern. However, evidence on post-acute COVID-19 syndrome (post-COVID-19) is still limited, particularly for children and adolescents. Utilizing comprehensive healthcare data on approximately 46% of the German population, we investigated post-COVID-19-associated morbidity in children/adolescents and adults. METHODS AND FINDINGS: We used routine data from German statutory health insurance organizations covering the period between January 1, 2019 and December 31, 2020. The base population included all individuals insured for at least 1 day in 2020. Based on documented diagnoses, we identified individuals with polymerase chain reaction (PCR)-confirmed COVID-19 through June 30, 2020. A control cohort was assigned using 1:5 exact matching on age and sex, and propensity score matching on preexisting medical conditions. The date of COVID-19 diagnosis was used as index date for both cohorts, which were followed for incident morbidity outcomes documented in the second quarter after index date or later.Overall, 96 prespecified outcomes were aggregated into 13 diagnosis/symptom complexes and 3 domains (physical health, mental health, and physical/mental overlap domain). We used Poisson regression to estimate incidence rate ratios (IRRs) with 95% confidence intervals (95% CIs). The study population included 11,950 children/adolescents (48.1% female, 67.2% aged between 0 and 11 years) and 145,184 adults (60.2% female, 51.1% aged between 18 and 49 years). The mean follow-up time was 236 days (standard deviation (SD) = 44 days, range = 121 to 339 days) in children/adolescents and 254 days (SD = 36 days, range = 93 to 340 days) in adults. COVID-19 and control cohort were well balanced regarding covariates. The specific outcomes with the highest IRR and an incidence rate (IR) of at least 1/100 person-years in the COVID-19 cohort in children and adolescents were malaise/fatigue/exhaustion (IRR: 2.28, 95% CI: 1.71 to 3.06, p < 0.01, IR COVID-19: 12.58, IR Control: 5.51), cough (IRR: 1.74, 95% CI: 1.48 to 2.04, p < 0.01, IR COVID-19: 36.56, IR Control: 21.06), and throat/chest pain (IRR: 1.72, 95% CI: 1.39 to 2.12, p < 0.01, IR COVID-19: 20.01, IR Control: 11.66). In adults, these included disturbances of smell and taste (IRR: 6.69, 95% CI: 5.88 to 7.60, p < 0.01, IR COVID-19: 12.42, IR Control: 1.86), fever (IRR: 3.33, 95% CI: 3.01 to 3.68, p < 0.01, IR COVID-19: 11.53, IR Control: 3.46), and dyspnea (IRR: 2.88, 95% CI: 2.74 to 3.02, p < 0.01, IR COVID-19: 43.91, IR Control: 15.27). For all health outcomes combined, IRs per 1,000 person-years in the COVID-19 cohort were significantly higher than those in the control cohort in both children/adolescents (IRR: 1.30, 95% CI: 1.25 to 1.35, p < 0.01, IR COVID-19: 436.91, IR Control: 335.98) and adults (IRR: 1.33, 95% CI: 1.31 to 1.34, p < 0.01, IR COVID-19: 615.82, IR Control: 464.15). The relative magnitude of increased documented morbidity was similar for the physical, mental, and physical/mental overlap domain. In the COVID-19 cohort, IRs were significantly higher in all 13 diagnosis/symptom complexes in adults and in 10 diagnosis/symptom complexes in children/adolescents. IRR estimates were similar for age groups 0 to 11 and 12 to 17. IRs in children/adolescents were consistently lower than those in adults. Limitations of our study include potentially unmeasured confounding and detection bias. CONCLUSIONS: In this retrospective matched cohort study, we observed significant new onset morbidity in children, adolescents, and adults across 13 prespecified diagnosis/symptom complexes, following COVID-19 infection. These findings expand the existing available evidence on post-COVID-19 conditions in younger age groups and confirm previous findings in adults.

HINTERGRUND UND ZIELE: Lichen planus (LP) ist eine chronisch entzündliche Hauterkrankung, die eine große Belastung für die betroffenen Patienten darstellt. Es liegen jedoch nur wenige Daten zu dieser Erkrankung vor. Ziel dieser Studie ist es, das Wissen über die Epidemiologie und die Behandlungsmuster des LP anhand von Abrechnungsdaten deutscher Krankenkassen zu erweitern. PATIENTEN UND METHODEN: Diese retrospektive Beobachtungsstudie nutzte die InGef-Forschungsdatenbank. Es wurden prävalente und inzidente LP-Patienten aus den Jahren 2015 und 2018 identifiziert. Für demografische Charakteristika, Behandlungsmuster und Komorbidität wurden deskriptive Statistiken berechnet. ERGEBNISSE: Die Prävalenz des LP lag bei 95,9 und die Inzidenz bei 20,1 pro 100 000 Personen im Jahr 2018, was 79 605 prävalenten LP-Fällen in Deutschland entspricht. Die erste LP-Diagnose wurde in der Regel von einem Dermatologen oder Hausarzt gestellt. Drei Viertel der inzidenten und die Hälfte der prävalenten Patienten erhielten eine topische Therapie, meist ohne zusätzliche systemische Therapie. Die Komorbidität des LP stand im Einklang mit bereits bekannten Assoziationen. SCHLUSSFOLGERUNGEN: Die verfügbaren Therapieoptionen sind nach wie vor begrenzt, was den ungedeckten Bedarf an sicheren und wirksamen systemischen Behandlungsmodalitäten unterstreicht. Der LP ist häufig mit klinisch relevanter systemischer Komorbidität verbunden. Zusammengenommen könnten diese Beobachtungen zu einem verbesserten Verständnis der Krankheitslast führen und das diagnostische Bewusstsein für diese Erkrankung unter Klinikern schärfen.
RESUMO
BACKGROUND AND OBJECTIVES: Lichen planus (LP) is a chronic inflammatory skin disease and is a major burden for affected patients. However, data on this condition are scarce. This study aims to expand the knowledge on the epidemiology and treatment patterns of LP using German health claims data. PATIENTS AND METHODS: This retrospective observational study was based on the InGef research database. Prevalent and incident LP patients were identified in the years 2015 and 2018. Descriptive statistics were calculated for demographic characteristics, treatment patterns, and comorbidity. RESULTS: The prevalence of LP was 95.9 and the incidence was 20.1 per 100,000 individuals in 2018, corresponding to 79,605 prevalent LP cases in Germany. The first LP diagnosis was generally documented by a dermatologist or a primary care physician. Three-quarters of the incident and half of the prevalent patients received topical therapy, mostly without further systemic therapy. Comorbidity in LP patients was consistent with previously known associations. CONCLUSIONS: Available treatment options remain limited, underscoring the unmet need for safe and efficacious systemic treatment modalities. Lichen planus is frequently accompanied by clinically relevant systemic comorbidity. Taken together, these observations may improve our understanding of the burden of this disease and increase diagnostic awareness among clinicians.

Toxoplasmosis is a zoonotic infection contracted through Toxoplasma gondii-contaminated food, soil, or water. Seroprevalence in Germany is high, but estimates of disease incidence are scarce. We investigated incidences for various toxoplasmosis manifestations using anonymized healthcare claims data from Germany for 2011-2016. Patients with a toxoplasmosis diagnosis during the annual observational period were considered incident. The estimated incidence was adjusted to the general population age/sex distribution. We estimated an annual average of 8,047 toxoplasmosis patients in Germany. The average incidence of non-pregnancy-associated toxoplasmosis patients was 9.6/100,000 population. The incidence was highest in 2011, at 10.6 (95% CI 9.4-12.6)/100,000 population, and lowest in 2016, at 8.0 (95% CI 7.0-9.4)/100,000 population. The average incidence of toxoplasmosis during pregnancy was 40.3/100,000 pregnancies. We demonstrate a substantial toxoplasmosis disease burden in Germany. Public health and food safety authorities should implement toxoplasmosis-specific prevention programs.

The majority of lung cancer patients are diagnosed with an advanced stage IV, which has short survival time. Many lung cancer patients have comorbidities, which influence treatment and patients' quality of life. The aim of the study is to describe comorbidities in incident lung cancer patients and explore their attendance of ambulatory care physicians in Germany. In the observed period, 13,111 persons were first diagnosed with lung cancer (1-year incidence of 36.4 per 100,000). The mean number of comorbidities over 4 quarters was 30.77 ± 13.18; mean Charlson Comorbidity Index was 6.66 ± 2.24. In Germany, ambulatory care physicians most attended were general practitioners (2.6 quarters with contact within 4 quarters). Lung cancer was diagnosed by a general practitioner in 38% of the 13,111 incident patients. The average number of ambulatory care physician contacts over 4 quarters was 35.82 ± 27.31. High numbers of comorbidities and contacts in ambulatory care are common in patients with lung cancer. Therefore, a cross-sectoral and interdisciplinary approach is required for effective, patient-centred care. This was a 5-year cross-sectoral study, based on the InGef research database, which covers anonymized health insurance data of 7.2 million individuals in Germany. Incident lung cancer patients in a 5-year period (2013-2017) were identified. Descriptive statistics were calculated for sociodemographic characteristics, comorbidities, and attendance of ambulatory care physicians.

OBJECTIVES: Since the beginning of the severe acute respiratory syndrome coronavirus 2 pandemic, there is a discussion about the severity of coronavirus disease-2019 (COVID-19) in comparison to infections with seasonal Influenza. The objective of this study was to compare clinical and demographic characteristics of German patients hospitalized for infection with either SARS-CoV-2 or Influenza. METHODS: This study used anonymized German healthcare claims data. Patients with a confirmed COVID-19 or Influenza diagnosis, for whom a complete hospital course was available (i.e., the patient was discharged or died in hospital) were included. The data set included detailed information on patient characteristics and hospital treatment. Patients were grouped according to whether they were transferred to the intensive care unit (ICU), received mechanical ventilation (MV), or had a severe course of the disease (SD). Charlson Comorbidity Index in the eight quarters prior to hospitalization and secondary diagnoses during hospitalization were analyzed. RESULTS: A total of 2343 hospitalized patients with COVID-19 and 6762 hospitalized patients with Influenza were included. Fifty-four percent of the patients were male patients, with men being twice as frequent in the COVID-19 severe groups. For both diseases, patients >49 years accounted for almost three-quarters of hospital cases and hypertension, diabetes mellitus, chronic kidney disease, and chronic obstructive pulmonary disease were the most common comorbidities. The proportion of cases with ICU, MV, and SD was substantially higher for patients with COVID-19 (ICU+: 21 vs. 13 %; MV+: 15 vs. 9%; and SD+: 28 vs. 16%). Overall inhospital mortality was more than two-fold higher in COVID-19 vs. Influenza (14 vs. 6%).). The length of ventilation and hospitalization, and the proportion of patients diagnosed with acute respiratory distress syndrome, systemic inflammatory response syndrome, or acute kidney injury were considerably higher in patients with COVID-19. CONCLUSIONS: COVID-19 resulted in higher inhospital mortality and worse clinical outcomes than Influenza. This was not attributable to demographic characteristics, preexisting comorbidities, or patient triage, because the German healthcare system had not reached its limits in the pandemic. Discussions suggesting that COVID-19 and seasonal Influenza have similar severity cannot be based on clinical evidence.

BACKGROUND: Infections during pregnancy are one of the leading causes of increased morbidity and mortality in mothers and their newborns worldwide. In Germany, there has been standardized healthcare for pregnancy for more than 50 years. The maternity guidelines of the Joint Federal Committee form the legal framework for this and include the screening of pregnant women for HIV, syphilis, and hepatitis B, among other things. AIM OF THE WORK: The aim of this work is to determine the extent to which screening is covered by the German population. MATERIAL AND METHODS: With the help of anonymized routine data of legally insured persons available to the Institut für angewandte Gesundheitsforschung Berlin GmbH (InGef) from 2011 to 2015, a definition of pregnancy was developed with the use of various ICD-10 and EBM codes and the first evaluation of the use of tests for infectious agents in pregnancy was carried out. RESULTS: The high proportion of women who are tested for syphilis (95.3%) and hepatitis B (91.6%) during pregnancy indicates very good accessibility and use of prenatal screening services. For HIV, the proportion of women tested is significantly lower (84.9%). DISCUSSION: Whether pregnant women refuse an HIV test, the test was performed elsewhere, or not recommended by the medical staff cannot be clarified on the basis of the available data. In view of the highly effective medical intervention options for syphilis, HIV, and hepatitis B, the aim should be to test pregnant women in Germany as completely as possible. The reasons for the lack of screening must be further investigated and starting points for increasing the use must be identified.

BACKGROUND: Post-traumatic stress disorders (PTSD) pose a high burden for individuals and societies. Although prevalence rates are rather low, high co-occurrence rates and overall impairments cause deleterious suffering and significant costs. Still, no long-term data on costs and trends in cost developments are available. METHODS: Claims data from a German research database were analysed regarding direct and indirect costs occurring for individuals with incident diagnoses of PTSD. Results were compared to non-exposed average insurants matched on age and gender. Costs were analysed over a 5-year period from 2 years preceding until 3 years following an incident diagnosis of PTSD. RESULTS: Overall costs for PTSD account for approximately 43,000 EUR per individual, which is three times higher than costs for non-exposed controls. Of these costs, 59% are caused by mental disorders, 18% specifically by PTSD. In the control group, costs for mental disorders account for 19% of total costs. Costs increase by 142% in the year after an incident diagnosis of PTSD but return to the initial level 2 years later. Still, costs are at least twice as high in every year as in those for the comparison group. CONCLUSIONS: Individuals with PTSD seem to suffer from far more impairments in their general health conditions and incur many more costs than average insurants. Most of these seem to be caused by co-occurring mental disorders and show their maximum in the index year. Nevertheless, as costs decrease to their initial level, treatments seem to have counterbalanced the impairments due to PTSD. Thus, treatments for PTSD can be considered as beneficial and their cost-effectiveness should be further investigated.

BACKGROUND: Claims data are a valuable data source to investigate the economic impact of new health care services. While the date of enrollment into the new service is an obvious start of follow-up for participants, the strategy to select potential controls is not straightforward due to a missing start of follow-up to ascertain possible confounders. The aim of this study was to compare different approaches to select controls via Propensity Score Matching (PSM) using the disease management program (DMP) bronchial asthma (BA) as an example. METHODS: We conducted a retrospective cohort study of BA patients between 2013 and 2016 to examine total one-year health care costs and all-cause mortality. We implemented different scenarios regarding the selection of potential controls: I) allotment of a random index date with subsequent PSM, II) calendar year-based PSM (landmark analysis) and III) calendar quarter-based PSM. In scenario I, we applied 2 approaches to assign a random index date: a) assign random index date among all quarters with a BA diagnosis and b) assign random index date and thereafter examine if a BA diagnosis was documented in that quarter. RESULTS: No significant differences in total one-year health care costs between DMP BA participants and non-participants were observed in any of the scenarios. This could to some extent be explained by the higher mortality in the control groups in all scenarios. CONCLUSION: If the loss of potential controls can be compensated, scenario Ib is a pragmatic option to select a control group. If that is not the case, scenario III is the more sophisticated approach, with the limitation that baseline characteristics prior PSM cannot be depicted and computational time or memory size needed to conduct the analysis need to be sufficient.

Geriatric characteristics such as high age, multi-morbidity, polypharmacy and frailty are common in patients with atrial fibrillation (AF). In a retrospective study using a German claims database, effectiveness (ischaemic stroke/systemic embolism) and safety (intracerebral, gastrointestinal and major extracranial bleeding) were compared in patients with non-valvular AF starting non-vitamin K oral antagonists (NOACs) (apixaban, dabigatran and rivaroxaban) and phenprocoumon. Cox proportional hazards models were used to calculate adjusted hazard ratios, and interaction terms of the treatment group and geriatric status (defined by age ≥75 years, frailty, ≥ 4 co-morbidities and polypharmacy) were entered into the model. A total of 42,562 and 27,939 patients initiated NOAC and phenprocoumon treatment (mean age 74 years ± 11, 51% male) with a follow-up time of 147,785 person-years. Note that 52.9% of patients were elderly, 50.8% were frail, 37.0% were co-morbid and 46.5% had polypharmacy. NOAC use was not associated with effectiveness and gastrointestinal bleeding, neither in geriatric nor in non-geriatric patients. The hazard of major extracranial and intracranial bleeding was significantly decreased for NOAC use, with similar risk reduction in geriatric and non-geriatric patients: major extracranial bleeding 0.70 (95% confidence interval [CI], 0.56-0.87) to 0.73 (95% CI, 0.60-0.89) for the geriatric groups and 0.71 (95% CI, 0.56-0.93) to 0.76 (0.59-0.98) for the non-geriatric groups (p-values for interaction > 0.6); and intracranial bleeding 0.52 (95% CI, 0.39-0.69) to 0.59 (95% CI, 0.47-0.73) for the geriatric groups and 0.54 (95% CI, 0.37-0.79) to 0.65 (95% CI, 0.49-0.86) for the non-geriatric groups (p-values for interaction > 0.2). Hence, NOACs showed similar effectiveness and superior safety in geriatric and non-geriatric patients.

BACKGROUND: Hypertrophic cardiomyopathy (HCM) is the most common inherited heart disease. Reported prevalence rates vary substantially between 1:500 (0.2%) and 1:3,000 (0.03%), which may be attributed to different study designs and population characteristics. Prevalence data for Germany is not available. Consequently, this study aimed (1) to quantify age- and gender-specific clinically diagnosed HCM prevalence in Germany based on the analysis of health care claims data of > 5 million insurants in 2015, and (2) to analyze temporal prevalence trends from 2011 to 2015. METHODS: Data were extracted from the InGef (Insitute for Applied Health Research) database, which is an anonymized healthcare claims database with longitudinal data from patients insured in one of approximately 70 German social health insurances (SHIs). Patients were classified as HCM prevalent, if they had at least one verified ambulatory or one hospital main- or secondary discharge diagnosis of HCM (I42.1 or I42.2). RESULTS: In 2015, HCM was prevalent in 4,000 out of 5,490,810 patients (0.07%; 1:1,372). HCM prevalence increased gradually with age from 7.4/100,000 persons (95% CI 5.2-10.1) in 0-9 years old to 298.7/100,000 persons (95% CI 276.4-322.4) in patients > 80 years. In all age categories, men had a numerically higher prevalence than women with significant differences in patients > 30 years. There was a gradual annual prevalence increase from 75.8 (95% CI 75.2-76.4) in 2011 to 84.2 (95% CI 83.5-84.8) in 2015 per 100,000 persons. CONCLUSIONS: Overall, prevalence of clinically diagnosed HCM in Germany is lower than in systematic population studies based on echocardiographic diagnosis. Prevalence increased with advancing age and showed a constant yearly rise. Those observations may improve our understanding of the burden of this genetic heart disease on the health care system in Germany, increase the diagnostic awareness among clinicians and shape future screening and management strategies.

BACKGROUND: Chronic heart failure (HF) is associated with significant healthcare expenditure, morbidity, and mortality. This study investigated the epidemiology of HF in Germany. METHODS: This retrospective study used anonymous healthcare claims data from the German Health Risk Institute on individuals with statutory health insurance. Patients with uninterrupted data from 1 January 2009 to 31 December 2013 or death (whichever occurred first), and ≥2 recorded HF-related diagnoses in 2011, were included. Patients with newly diagnosed HF were identified. Patients were followed up for 2 years from first diagnosis. RESULTS: Of 3,132,337 eligible patients, 123,925 (55.0% women; mean age 76.2 years) had HF: a prevalence of 3.96%. Of these, 26,368 had newly diagnosed HF: an incidence of 655/100,000 persons at risk. Incidence increased with age and was similar regardless of sex. During follow-up, there were 48,159 hospital admissions among newly diagnosed patients (1.8 hospitalizations/patient/2 years); HF accounted for 6% of these. Additionally, 20,148 patients (16.3%) overall and 5983 newly diagnosed patients (22.7%) died. Most new cases of HF were diagnosed by office-based physicians (63.2%); new cases among hospital inpatients were predominantly diagnosed by internal medicine specialists (70.7%). Overall, 94.0% received their initial prescription for HF treatment from a family practitioner. CONCLUSIONS: The high prevalence and incidence observed in this representative sample emphasize the burden of HF in Germany. Substantial hospitalization rates and mortality highlight the need for early diagnosis and appropriate treatment, and for close cooperation between physician specialties and healthcare sectors.

BACKGROUND: Adherence to treatment guidelines affects outcomes in patients with chronic heart failure (HF). We investigated patient pathways and treatment patterns for HF in Germany. METHODS: This retrospective study used anonymous healthcare claims data from the German Health Risk Institute on individuals with statutory health insurance. Patients with uninterrupted data from 1 January 2009 to 31 December 2013 or death (whichever occurred first), and ≥2 recorded HF-related diagnoses in 2011, were included. Patients with newly diagnosed HF were identified. Use of treatment patterns recommended by the European Society of Cardiology (2008) and German Nationale VersorgungsLeitlinien (2011) guidelines was evaluated. RESULTS: Of 123,925 patients with HF, 21.3% were newly diagnosed. Overall, 63.2% of new HF diagnoses were made in the ambulatory setting; 61.6% of these were made by family practitioners and 14.8% by cardiologists. In the ambulatory setting, family practitioners were primarily responsible for treatment; specialists in internal medicine (70.3% cardiologists) were mainly responsible for performing HF-related technical diagnostics. One-fifth (20.9%) of patients received a New York Heart Association (NYHA) classification; 45.1% of these received a guideline-based treatment pattern. Application of the recommended treatment pattern decreased with advancing disease severity (NYHA class IV: 21.1% application) and older age (≥90 years: 28.3% application). CONCLUSIONS: Family practitioners play a key role in the diagnosis and initial treatment of HF in Germany. A substantial proportion of patients do not receive guideline-recommended pharmacotherapy. These findings should be reflected in the planning of national disease management programmes.
