We analyzed routine statutory health insurance claim data to determine prevalence of nontuberculous mycobacterial pulmonary disease in Germany. Documented prevalence rates of this nonnotifiable disease increased from 2.3 to 3.3 cases/100,000 population from 2009 to 2014. Prevalence showed a strong association with advanced age and chronic obstructive pulmonary disease.
Bronchiectasis is a chronic and progressive disease, which frequently is associated with a significant symptom burden and which may require intensive treatment. To date, epidemiological data on the prevalence of bronchiectasis in Europe are exceedingly scarce due to a great lack of research [1]. However, these data on disease burden are important in order to inform authorities and to allocate resources in healthcare [2], in particular as bronchiectasis is associated with high healthcare system usage as well as significant morbidity and mortality [3,4]. The aim of the present study was to estimate the overall prevalence of bronchiectasis in Germany over a 1-year period from a representative sample of routine statutory health insurance claim data, with special attention paid to the distribution of age and sex, and the site of healthcare provision, as well as chronic obstructive pulmonary disease (COPD) as a concomitant condition.
α-Antitrypsin deficiency (AATD) is a genetically determined disorder that is associated with different clinical manifestations. We aimed to assess the prevalence of diagnosed AATD and its comorbidities using a large healthcare database.In this retrospective longitudinal observational study, we analysed data from 4 million insurants. Using International Classification of Diseases revision 10 (ICD-10) codes, we assessed the prevalence, comorbidities and healthcare utilisation of AATD patients (E88.0 repeatedly coded) relative to non-AATD patients with chronic obstructive pulmonary disease (COPD), emphysema or asthma.In our study population, we identified 673 AATD patients (590 aged ≥30 years), corresponding to a prevalence of 23.73 per 100 000 in all age groups and 29.36 per 100 000 in those ≥30 years. Based on the number of AATD cases detected in the sample size (673 out of 2 836 585), we extrapolated that there were 19 162 AATD cases in Germany during the years studied. AATD patients had a higher prevalence of arterial hypertension, chronic kidney disease and diabetes relative to non-AATD asthma or emphysema patients. When compared to non-AATD COPD patients, AATD patients had significantly more consultations and more frequent and longer hospitalisations.Our data strengthen the assumption that AATD is associated with a variety of other diseases. Healthcare utilisation appears to be higher among AATD patients as compared to patients with non-AATD-related obstructive lung diseases.
IntroductionWe present a new approach to evaluate the importance of ambulatory nephrology care in patients with chronic kidney disease (CKD).MethodsAn anonymized health claims database of German insurance companies was searched in a retrospective analysis for patients with CKD using the codes of the International Classification of Diseases, 10th German modification. A total of 105,219 patients with CKD were identified. Patients were assigned to the group “timely referral,” when nephrology care was present in the starting year 2009, or initiated during the following 3 years in CKD1–4. Using frequency matching for age and gender, 21,024 of the late referral group were matched with the equal number of patients in the timely referral group. Hospital admission rates, total treatment costs, and kidney function (change in CKD stages, start of dialysis, mortality) were documented each year during the 4-year follow-up.ResultsHospital admission rates (110%–186%) and total treatment costs (119%–160%) were significantly higher (P < 0.03) in late referral compared with timely referral. In the timely referral group, significantly more patients did not change their CKD stage (65%–72.9% vs. 52%–64.6%, P < 0.05) compared with late referral. Starting in CKD3 more patients tended to start dialysis in 1 year in timely referral (1.9 ± 0.6 vs. 1.0 ± 0.4, P = 0.1). In contrast, death rates were significantly higher in the late referral group (18.8 ± 1.8% vs. 6.7 ± 0.4%, P = 0.0001).DiscussionTimely referral to outpatient nephrology care is associated with slowed disease progression, less hospital admissions, reduced total treatment costs, and improved survival in patients with CKD.
Purpose Bisphosphonates and denosumab prevent bone complications in patients with bone metastases from solid tumours. This retrospective, longitudinal, cohort study provides data on their real-world use in this setting in Germany. Methods Adults with bone metastases from breast, prostate or lung cancer who were newly initiated on a bisphosphonate or denosumab between 1 July 2011 and 31 December 2015 were identified from a German healthcare insurance claims database. Primary outcomes included persistence, compliance, discontinuation and switch rates at 12 months. Results This study included 1130 patients with bone metastases: 555 (49%) had breast cancer, 361 (32%) prostate cancer and 242 (21%) lung cancer. Mean age was 65 years for patients with breast or lung cancer and 74 years for those with prostate cancer. Across all tumour types, compared with any bisphosphonate, 12-month persistence was higher with denosumab (breast cancer 78% vs 54-58%, prostate cancer 58% vs 50%, lung cancer 68% vs 34-60%), median time to discontinuation was longer with denosumab and switch rates were lower for denosumab (breast cancer 5% vs 14-19%, prostate cancer 2% vs 11%, lung cancer 3% vs 7-12%). Compliance at 12 months was longer for denosumab than for any bisphosphonate in breast cancer (75% vs 42-48%) and in prostate cancer (47% vs 36%). Conclusions Patients initiated on denosumab following a diagnosis of bone metastases from breast, prostate or lung cancer had greater medication persistence, longer time to discontinuation, improved compliance and lower switch rates than those initiated on a bisphosphonate.
