Abstract The complexity and diversity of surgical/interventional vascular medicine necessitate innovative and pragmatic solutions for the valid measurement of the quality of care in the long term. The secondary utilization of routinely collected data from social insurance institutions has increasingly become the focus of interdisciplinary medicine over the years. Owing to their longitudinal linkage and pan-sector generation, routinely collected data make it possible to answer important questions and can complement quality development projects with primary registry data. Various guidelines exist for their usage, linkage, and reporting. Studies have shown good validity, especially for endpoints with major clinical relevance. The numerous advantages of routinely collected data face several challenges that require thorough plausibility and validity procedures and distinctive methodological expertise. This review presents a discussion of these advantages and challenges and provides recommendations for starting to use this increasingly important source of data.
Previous studies have repeatedly reported alcohol use disorders (AUDs) in patients after bariatric surgery (BS). This research field can benefit from studies combining health claims data with survey data.
ObjectiveThis study aimed to determine predictors and outcomes associated with bleeding or anemia requiring transfusion (BAT) after fenestrated or branched endovascular aneurysm repair (FB-EVAR).MethodsHealth insurance claims data of Germany's third largest insurance provider, DAK-Gesundheit, were used to investigate BAT in elective FB-EVAR performed between 2008 and 2017. International Classification of Diseases and German Operations and Procedure Key codes were used.ResultsA total of 959 patients (24.8% with BAT) matching the inclusion criteria were identified during the study period. Compared with patients without BAT, patients with BAT were older (74.4 vs 73.0 years; P = .015) and suffered more frequently from congestive heart failure (18.5% vs 9.4%), cardiac arrhythmias (26.9% vs 14.7%), and hereditary or acquired coagulopathy (31.9% vs 6.2%; all P < .001). Coagulopathy (odds ratio [OR], 3.65; 95% confidence interval [CI], 2.29-5.84), female sex (OR, 2.67; 95% CI, 1.78-4.00), and multiple comorbidities (OR, 1.10; 95% CI, 1.07-1.14) were independent predictors of BAT (all P < .001). BAT was associated with higher in-hospital (11.3% vs 2.6%), 30-day (12.2% vs 3.1%), and 90-day (18.5% vs 4.4%) mortality (all P < .001). Furthermore, myocardial infarction (23.9% vs 2.8%) and paraplegia (9.7% vs 0.7%) were more frequent in the BAT group (all P < .001). In multivariable analyses, BAT was associated with worse short-term (OR, 3.19; 95% CI, 1.63-6.33; P = .001) and long-term survival (hazard ratio, 1.62; 95% CI, 1.24-2.11; P < .001).ConclusionsPatients with hereditary or acquired coagulopathy, patients with multiple comorbidities, and women are at higher risk for development of BAT after FB-EVAR. The occurrence of this event was strongly associated with higher major complication rates and worse short-term and long-term survival. This emphasizes a need to further illuminate the value of patient blood management in FB-EVAR.
ObjectiveThis study aimed to determine predictors and outcomes associated with spinal cord ischemia (SCI) after elective fenestrated or branched endovascular aneurysm repair (F/BEVAR) of thoracoabdominal aortic aneurysm (TAAA), abdominal aortic aneurysm (AAA), or aortic dissection.MethodsHealth insurance claims data of Germany's third largest insurance provider, DAK-Gesundheit, were used to investigate SCI in elective F/BEVAR performed between 2008 and 2017. The International Classification of Diseases and German Operation and Procedure Classification System were used. We stratified the results into F/BEVAR with one or two (AAA) vs three or more (TAAA) fenestrations or branches.ResultsA total of 877 patients (18.9% female; 5.8% with SCI) matching the inclusion criteria were identified during the study period. SCI occurred more often after F/BEVAR of TAAA vs AAA (10.7% vs 3.0%; P < .001). SCI was associated with female sex in the AAA group (odds ratio, 3.87; 95% confidence interval [CI], 1.25-11.15; P = .014) and with cardiac arrhythmias in the TAAA group (odds ratio, 2.98; 95% CI, 1.24-7.06; P = .013). Compared with patients without SCI, SCI patients were more likely to suffer from drug use disorders (eg, opioids, cannabinoids, sedatives) in the TAAA group (17.6% vs 2.1%; P < .05). After F/BEVAR of TAAA, the occurrence of SCI was associated with higher 90-day mortality (14.7% vs 1.1%; P < .05), longer postoperative hospital stay (22 vs 9 days; P < .05), and severe adverse events, such as acute respiratory insufficiency (44.1% vs 12.7%), acute renal failure (35.3% vs 11.3%), and pneumonia (29.4% vs 4.9%; all P < .05). In adjusted analyses, SCI was associated with worse long-term survival after F/BEVAR for TAAA (hazard ratio, 2.54; 95% CI, 1.37-4.73; P < .003).ConclusionsFemale AAA patients and TAAA patients with cardiac arrhythmias are at highest risk for development of SCI after F/BEVAR. The occurrence of this event was strongly associated with higher major complication rates and worse short-term and long-term survival. This emphasizes a need to further illuminate the value of spinal cord protection protocols in F/BEVAR.
Objective: Previous studies have showed a potential disadvantage of female patients who underwent abdominal aortic aneurysm (AAA) repair. The current study aims to determine sex-specific perioperative and long-term outcomes using propensity score matched unselected nationwide health insurance claims data. Methods: Insurance claims from a large German fund were used, covering around 8% of the insured German population. Patients who underwent endovascular aortic repair (EVAR) for intact AAA from 1 January 2011 to 30 April 2017 were included in the cohort. A 1:2 female to male propensity score matching was applied to adjust for confounding variables. Perioperative and long-term outcomes after 5 years were determined using matching and regression methods. Results: Among a total of 3736 patients (19.3% females, mean 75 years) undergoing EVAR for intact AAA, we identified 1863 matched patients. Before matching, females were more likely to be previously diagnosed with hypothyroidism, electrolyte disorders, rheumatoid disorders, and depression, while males were more often diabetics. In the matched sample, 23.4% of the females and 25.8% of the males died during a median follow-up of 776 and 792 days, respectively. Perioperatively, females were more likely to exhibit acute limb ischemia (5.3% vs. 3.2%, p = 0.031) and major bleeding (22.0% vs. 15.9%, p = 0.001) before they were discharged to rehabilitation (5.5% vs. 1.5%, p < 0.001) when compared to males. No statistically significant difference in perioperative (odds ratio 1.12, 95% CI 0.54–2.16) or long-term mortality (hazard ratio 0.91, 95% CI 0.76–1.08) was observed between sexes. This was also true regarding aortic reintervention rates after 1 year (2.0% vs. 2.9%) and 5 years (10.9% vs. 8.1%). Conclusion: The current retrospective matched analysis of insurance claims revealed high early access-related morbidity in females when compared to their male counterparts. Short-term or long-term survival and reintervention outcomes were similar between sexes.
Herz-Kreislauf-Erkrankungen sind die Todesursache Nummer eins in Deutschland und gehören stärker in das Zentrum der Diskussion – wissenschaftlich, gesellschaftlich und politisch. Im Beitrag von Im Puls. Think Tank Herz-Kreislauf wird dieser holistische Ansatz verfolgt. Experten aus Politik, Wissenschaft, Ärzteschaft, Krankenkassen, Verbänden, Patientenorganisationen, Ethik und Gesundheitswirtschaft betrachten das Thema Herz-Kreislauf-Erkrankungen erstmals krankheitsbilderübergreifend. Im Zentrum der Diskussion steht das „tödliche Quintett“, bestehend aus Herzerkrankungen, Bluthochdruck, Fettstoffwechselstörungen, Diabetes und Adipositas. Ziel ist es, die Aufmerksamkeit und das Bewusstsein für Herz-Kreislauf-Erkrankungen in allen Lebenswelten zu verbessern. Hierfür arbeitet der Think Tank eng mit Experten aus den Bereichen Ernährung, Bewegung, Arbeit und Soziales zusammen, um Rahmenbedingungen für bedarfsgerechte Aufklärungs-, Präventions- und Therapiemaßnahmen zu entwickeln. Der Beitrag umfasst außerdem frische Ideen und Handlungsempfehlungen zur Entwicklung innovativer Versorgungsansätze, zur Gestaltung politischer Rahmenbedingungen und zur Verbesserung der Forschungssituation.
