BACKGROUND: @entity3147 is an established risk factor for @entity260 . The purpose of this investigation was to determine the overall prevalence of @entity3147 in @entity348 ( @entity348 ) @entity1 , the differences in prevalence across @entity28 subgroups, and the overall complication risk of malnourished @entity1 compared with normal @entity1 . METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried for @entity348 cases from 2005 to 2013 for this retrospective cohort study. @entity3147 was defined as preoperative albumin concentration of <3.5  g/dL. @entity260 were compared between normal and malnourished @entity1 . RESULTS: We identified 4,655 @entity348 cases, with preoperative albumin measurements available for 1681 @entity1 (36.1%). Propensity score adjustment successfully reduced selection bias, with adjusted P values of >.05 for demographics, body mass index, and modified Charlson Comorbidity Index. Of the cohort with albumin measurements, 7.6% of @entity1 were malnourished according to our criteria. Bivariate analysis showed malnourished @entity1 had higher rates of @entity358 , @entity417 requiring transfusion, extended length of stay (LOS), and @entity204 (all P  <  .05). Propensity-adjusted multivariable logistic regression demonstrated that @entity3147 was significantly associated (all P  <  .05) with postoperative transfusion (odds ratio, 2.49), extended LOS (odds ratio, 1.69), and @entity204 (odds ratio, 18.09). CONCLUSION: The overall prevalence of @entity3147 was 7.6%. Malnourished @entity1 were at a significantly increased risk for blood transfusion, longer hospital LOS, and @entity204 within 30  days of surgery. Multivariable analysis showed @entity348 @entity1 with preoperative albumin levels of <3.5  g/dL are at much higher risk for morbidity and @entity204 after surgery than @entity1 with albumin levels within normal reference ranges.
