Routine care for people with newly diagnosed type 2 diabetes before and during the SARS-CoV-2 pandemic - results from the German Disease Analyzer database.

AIM: To investigate whether the SARS-CoV-2 pandemic affected care for people with newly diagnosed type 2 diabetes in Germany. METHODS: The Disease Analyzer database (IQVIA, Germany) contains routine data on diagnoses and treatments (ICD-10 and ATC codes) from patients followed in selected physician practices across Germany. We compared 21,747 individuals with a first diagnosis of type 2 diabetes between January 2018 and September 2019 with 20,513 individuals with a first diabetes diagnosis between March 2020 and November 2021. RESULTS: In March and April 2020, the number of new diagnoses of diabetes decreased by 18.3% and 35.7%, respectively, compared to March and April of the previous two years. The previous diabetes incidence level was reached again in June 2020. Mean pre-treatment glucose levels were higher during the pandemic than before (fasting plasma glucose: +6.3 mg/dl (95% confidence interval: 4.6-8.0)). In the first six months after diabetes diagnosis, the mean number of GP visits, specialist referrals and HbA1c measurements decreased. CONCLUSION: We observed a decrease in diabetes incidence in the early phase of the pandemic and slightly higher pretreatment blood glucose levels during the pandemic than before. Care for newly diagnosed diabetes was slightly worse during the pandemic than before.

Effects of the COVID-19 pandemic on clinically diagnosed psychiatric disorders in persons with type 2 diabetes.

AIMS: To examine whether the incidence rates of diagnosed depression, anxiety disorders and stress reactions, as well as prescription rates of antidepressants and anxiolytics were higher during the COVID-19 pandemic than before in persons with type 2 diabetes in Germany. Contrary to earlier studies, clinical diagnoses of psychiatric disorders (ICD classification) were used. METHODS: The German Disease Analyzer (DA) database is an outpatient database containing routine data on patients´ diseases and treatments provided by a representative panel of physician practices selected from across Germany. We assessed incidence rates of depressive disorders (ICD-10: F32, F33), anxiety disorders (F41) and stress reactions (F43) in quarters from January 2019 to March 2021 in 95,765 people with type 2 diabetes included in the DA in 2019 (mean age 68.9 years, 58% men). Prescription rates of antidepressants and anxiolytics in quarters from January 2020 to March 2021 were compared with prescription rates from 1 year earlier. RESULTS: During the study period, the incidence rate of newly diagnosed depressive disorders in persons with type 2 diabetes declined slightly, while the incidence rates of anxiety and stress disorders remained largely constant. The rates of new prescriptions for antidepressants and anxiolytics were lower in all quarters of 2020 and in the first quarter of 2021 than in the quarters 1 year earlier. Diabetes-related complications were more prevalent in persons with incident psychiatric disorders than in those without. CONCLUSIONS: No increase in the incidence rates of clinically diagnosed psychiatric disorders was observed during the COVID-19 pandemic in Germany in persons with type 2 diabetes.

Effects of the COVID-19 lockdown on primary health care for persons with type 2 diabetes - Results from the German Disease Analyzer database.

OBJECTIVES: To identify the effects of the first lockdown in Germany (March to May 2020) on glycemic control, BMI, and cardiovascular risk factors in persons with type 2 diabetes. METHODS: The nationwide Disease Analyzer database includes a representative panel of physicians practices in Germany providing anonymized real-world patient data. For metabolic and renal factors, we estimated absolute changes of means comparing outcomes from June to November 2020 to outcomes in the same persons from June to November 2019, and June to November 2018, respectively. RESULTS: In 32,399 patients with type 2 diabetes, HbA1c change between 2019 and 2020 was + 0.04% (95 %CI: 0.03%; 0.05%) compared to -0.02% (95 %CI: -0.03%; -0.01%) between 2018 and 2019. Metabolic risk factors and creatinine changed only little between June to November 2019 and June to November 2020. The proportions of patients with BMI ≥ 30 kg/m2 were 56%, 55%, and 54% in June to November 2018, 2019, and 2020, respectively. The corresponding proportions for HbA1c > 53 mmol/mol Hb (>7.0%) were 39%, 39%, and 40%. CONCLUSIONS: There is little evidence that the first COVID-19 lockdown in Germany had a short-term harmful influence on acute health care outcomes and vascular risk factors in people with type 2 diabetes.
