Screening and diagnosis of micronutrient deficiencies before and after bariatric surgery

Research output: Contribution to journalArticle

Abstract

Background: Micronutrient deficiencies are key concerns after bariatric surgery. We describe the prevalence of perioperative testing and diagnosis of micronutrient deficiencies among a cohort of insured bariatric surgery patients. Methods: We used claims data from seven health insurers to identify bariatric surgery patients from 2002-2008. Our outcomes were perioperative claims for vitamin D, B12, folate, and iron testing and diagnosed deficiencies. We analyzed results by bariatric surgery type: Roux-en-Y gastric bypass (RYGB), restrictive, and malabsorptive. We calculated the prevalence of testing and deficiency diagnosis, and performed multivariate logistic regression to determine the association with surgery type. Results: Of 21,345 eligible patients, 84 % underwent RYGB. The pre-surgical testing prevalence for all micronutrients was
