Alcohol use disorders after bariatric surgery: a study using linked health claims and survey data.

Background: 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.

Methods: Based on a combined retrospective cohort and cross-sectional study, 2151 patients with BS identified in a large health claims database received a questionnaire, by which we assessed the presence of AUDs based on a validated instrument (AUDIT) as well as by ICD-10 codes from the health claims data.

Quality of life in bariatric patients up to twelve years after surgery - Results from a nationwide retrospective cohort study.

Background: Bariatric interventions (BI, including surgical interventions) are effective in patients with massive obesity, i.e., a body mass index (BMI) > 40, and their number has steadily increased during the past decade.

Female Sex and Outcomes after Endovascular Aneurysm Repair for Abdominal Aortic Aneurysm: A Propensity Score Matched Cohort Analysis.

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.

Incidence, predictors, and outcomes of spinal cord ischemia in elective complex endovascular aortic repair: An analysis of health insurance claims.

Objective: This 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.

Methods: Health 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.

Predictors of bleeding or anemia requiring transfusion in complex endovascular aortic repair and its impact on outcomes in health insurance claims.

Objective: This study aimed to determine predictors and outcomes associated with bleeding or anemia requiring transfusion (BAT) after fenestrated or branched endovascular aneurysm repair (FB-EVAR).

Methods: Health 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.
