Objectives: A lower-quality colonoscopy has been shown to be less effective in reducing colorectal cancer (CRC) incidence than a higher-quality colonoscopy, but the comparison with no-screening colonoscopy (noSC) is lacking. We aimed to compare the 13-year risk of developing CRC between persons with I) a higher-quality screening colonoscopy (higherQualSC), II) a lower-quality screening colonoscopy (lowerQualSC), and III) without a screening colonoscopy.
Study Design And Setting: A health-care database (∼20% of the German population) was used to emulate a target trial with three arms: higherQualSC vs lowerQualSC vs noSC at baseline.
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.
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.
