People with type 2 diabetes (T2D) are at elevated risk of cardiovascular disease (CVD) including stroke, yet existing real-world evidence (RWE) on the clinical and economic burden of stroke in this ...population is limited. The aim of this cohort study was to evaluate the clinical and economic burden of stroke among people with T2D in France.
We conducted a retrospective RWE study using data from the nationally representative subset of the French Système National des Données de Santé (SNDS) database. We assessed the incidence of stroke requiring hospitalization between 2012 and 2018 among T2D patients. Subsequent clinical outcomes including CVD, stroke recurrence, and mortality were estimated overall and according to stroke subtype (ischemic versus hemorrhagic). We also examined the treatment patterns for glucose-lowering agents and CVD agents, health care resource utilization and medical costs.
Among 45,331 people with T2D without baseline history of stroke, 2090 (4.6%) had an incident stroke requiring hospitalization. The incidence of ischemic stroke per 1000 person-years was 4.9-times higher than hemorrhagic stroke (6.80 95% confidence interval (CI) 6.47-7.15 versus 1.38 1.24-1.54). During a median follow-up of 2.4 years (interquartile range 0.6; 4.4) from date of index stroke, the rate of CVD, stroke recurrence and mortality per 1000 person-years was higher among hemorrhagic stroke patients than ischemic stroke patients (CVD 130.9 107.7-159.0 versus 126.4 117.2-136.4; stroke recurrence: 86.7 66.4-113.4 versus 66.5 59.2-74.6; mortality 291.5 259.1-327.9 versus 144.1 134.3-154.6). These differences were not statistically significant, except for mortality (adjusted hazard ratio 1.95 95% CI 1.66-2.92). The proportion of patients prescribed glucagon-like peptide-1 receptor agonists increased from 4.2% at baseline to 6.6% during follow-up. The proportion of patients prescribed antihypertensives and statins only increased slightly following incident stroke (antihypertensives: 70.9% pre-stroke versus 76.7% post-stroke; statins: 24.1% pre-stroke versus 30.0% post-stroke). Overall, 68.8% of patients had a subsequent hospitalization. Median total medical costs were €12,199 (6846; 22,378).
The high burden of stroke among people with T2D, along with the low proportion of patients receiving recommended treatments as per clinical guidelines, necessitates a strengthened and multidisciplinary approach to the CVD prevention and management in people with T2D.
•Retrospective cohort study using administrative claims database in Germany.•Assessment of outcomes in propensity-score matched acute graft-vs-host disease (aGVHD) and no GVHD cohorts.•aGVHD group ...had significantly higher odds of mortality than the no GVHD group.•Total direct costs were 1.6-fold higher in the aGVHD group versus the no GVHD group.
Acute graft-vs-host disease (aGVHD) is a serious complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT), yet there are limited data on the clinical and economic burden of aGVHD in Germany. This real-world study aimed to evaluate clinical and economic outcomes among patients in Germany with or without aGVHD after allo-HSCT.
This retrospective cohort study used administrative claims extracted from the German statutory health insurance database. Eligible adult patients underwent allo-HSCT between 1 January 2009 and 31 December 2017 for any hematological malignancy. Clinical (severe infections and mortality) and economic (health care resource use HCRU and costs) outcomes were compared in “aGVHD” patients and “no GVHD” patients. Propensity score matching (1:1) was used to balance covariates between the aGVHD and no GVHD groups.
After propensity score matching, 95 aGVHD and 95 no GVHD patients were included in the analysis. The aGVHD group had significantly higher odds of mortality than the no GVHD group (odds ratio OR 2.2; 95% CI 1.2-4.0). Odds of severe infection were similar between the 2 groups (OR 1.7; 95% CI 0.9-3.3). Patients in the aGVHD group had significantly more overnight hospitalizations per patient-year (mean SD: 3.7 3.0 and 2.7 2.5, P = .029), and total direct costs were 1.6-fold higher than those in the no GVHD group.
Among patients who underwent allo-HSCT, aGVHD was associated with significantly higher mortality, HCRU, and costs, highlighting the need for effective prophylaxis and treatment options to prevent or reduce the incidence of aGVHD.
Purpose
To assess real-world treatment patterns in patients diagnosed with hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) metastatic breast cancer (mBC) ...who received cyclin-dependent kinase 4/6 (CDK4/6) inhibitors in combination with an aromatase inhibitor (AI) or fulvestrant at first line.
Methods
Patient characteristics, treatment history, and outcomes data were extracted from the French ‘Système National des Données de Santé’ (SNDS) database for patients diagnosed with HR+/HER2- mBC between January 2014 and June 2019 and who received combination therapy with a CDK4/6 inhibitor and endocrine therapy. Kaplan-Meier methodology was used to assess time to next treatment (TTNT) and time to treatment discontinuation (TTTD).
Results
The cohort comprised 6061 patients including 4032 patients who received CDK4/6 inhibitors + AIs and 2029 patients who received CDK4/6 inhibitors + fulvestrant. Median follow-up was 13.5 months (IQR 9.5–18.1). The median TTTD of first line treatment with CDK4/6 inhibitors + AIs and CDK4/6 inhibitors + fulvestrant was 17.3 months (95% CI 16.8–17.9) and 9.7 months (95% CI 9.0–10.2), respectively. Chemotherapy was the most common second line therapy. Median TTTD of subsequent treatment lines was progressively shorter following first line treatment with CDK4/6 inhibitors + AIs (2nd line: 4.6 months (95% CI 4.4–4.9) and with CDK4/6 inhibitors + fulvestrant (2nd line: 4.7 months (95% CI 4.3–5.1). TTNT was longer than TTTD across lines of therapy.
Conclusion
This real-world analysis confirms the effectiveness of CDK4/6 inhibitor-based regimens in French patients and highlights the frequent use of chemotherapy as second line therapy.
