patients were heavier and more often male. Surgeons who were involved with malpractice claims were less often board-certified and more often foreign medical graduates than national norms. Hospitals involved with malpractice suits had a much lower accreditation rate in comparison to national norms. Malabsorptive and non-standard procedures were over-represented in malpractice claims in comparison to MBSAQIP procedure rates. While mortality was the most common cause for malpractice suits, Bleeding, Retained foreign body, and Vascular injury occurred at higher rates than national averages. Overall care determination found 37.4% of cases to be either preventable error or preventable. Failure to diagnose, Delay in Treatment, Postoperative Care and Communication domain responses from Expert Panel indicate future opportunities for improvement along with specific recom- mendations for prevention of retained foreign bodies and vascular injury following trocar placement. A106 GOALS VS. EXPECTATIONS: WHAT PATIENTS AND REFERRING PHYSICIANS SHOULD KNOW ABOUT WHO ACHIEVES A BMI < 30 KG/M 2 AFTER BARIATRIC SURGERY Oliver Varban 1 ; Ruth Cassidy 2 ; Anne Cain-Nielsen 2 ; Carl Pesta 3 ; Arthur Carlin 4 ; Amir Ghaferi 1 ; Jonathan Finks 1 ; 1 University of Michigan Health System, Ann Arbor MI; 2 Michigan Bariatric Surgery Collaborative, Ann Arbor MI; 3 Henry Ford Macomb Hospital, Mount Clemens Mi; 4 Henry Ford Hospital, Detroit MI Background: Achieving a BMI under 30 kg/m 2 is a key goal of bariatric surgery, given the increased risk for mortality with BMIs over this threshold. While bariatric surgery offers superior weight loss and comorbidity resolution when compared to medical management, less than half of patients will reach a BMI under 30 kg/m 2 after bariatric surgery. The goal of this study was to identify predictors for patients achieving this weight loss target. Methods: This study was conducted using data from the Michigan Bariatric Surgery Collaborative, a statewide consortium that uses a clinical data registry for quality improvement. We included patients who underwent a primary bariatric procedure between 2006 and 2015 and also completed surveys at baseline and at 1- year after surgery (n¼19764). Regression analysis was used to compare 30-day complications and 1-year comorbidity remission between patients who achieved BMI o 30 kg/m 2 and those who did not, adjusting for patient characteristics and procedure type. Comorbidity remission was defined as discontinuation of treatment for the condition in patients receiving treatment on baseline surveys. Logistic regression was used to identify predictors for achieving a BMI o 30 kg/m 2 at 1 year after surgery. Results: A total of 7528 patients (38%) achieved a BMI o 30 kg/ m 2 1 year after surgery. The mean age for this group was 47 years and the mean preoperative BMI was 42.6 kg/m 2 . The most common procedures performed in this group was gastric bypass (55.2%), followed by sleeve gastrectomy (38.0%), adjustable gastric banding (5.1%) and duodenal switch (1.7%). Overall risk adjusted 30-day complication rates were similar between the two groups (8.08% for BMI o 30kg/m 2 vs 7.04% for BMI 4¼ 30kg/ m 2 ,p¼0.69). Patients who achieved a BMI of less than 30 kg/m 2 had significantly higher rates of medication discontinuation for hyperlipidemia (60.7% vs 43.2%, po0.0001), diabetes (insulin: 67.7% vs 50.0%, po0.0001; oral medications 78.5% vs 64.3%, po0.0001), hypertension (54.7% vs 34.6%, po0.0001) as well as a significantly higher rate of sleep apnea remission (72.5% vs 49.3%, po0.0001) and higher satisfaction rate (92.8% vs 78.0%, po0.0001), when compared to patients who did not. Significant predictors of achieving a BMI o 30 kg/m 2 at 1 year after bariatric surgery included a preoperative BMI o 40 kg/m 2 (OR 13.31, CI 11.95-14.83, po0.0001) and private insurance (OR 1.12 CI 1.04- 1.21, p¼0.002). Patients who underwent gastric bypass, sleeve gastrectomy and duodenal switch also had a higher likelihood of achieving a BMI o 30 kg/m 2 , when compared to adjustable gastric banding (OR 19.1, 7.3 and 72.4, respectfully, po0.0001) Only 8% of patients with a BMI over 50 kg/m 2 achieved a BMI of less than 30 kg/m 2 after bariatric surgery. Patients who failed to achieve a BMI of 30 kg/m 2 at one year after bariatric surgery had significantly higher rates of preoperative hypertension (60.6% vs 49.3%, po0.0001), diabetes (38.8% vs 30.8%, po0.0001), asthma (21.4% vs 18.9%, po0.0086), mobility limitations (7.5% vs 3.0%, po0.0001), and obstructive sleep apnea (50.5% vs 40.3%, po0.0001). Conclusions: Patients achieving a BMI o 30 kg/m 2 1 year after bariatric surgery had a significantly higher rate of comorbidity remission and were more satisfied. Healthier patients with private insurance and a preoperative BMI o 40kg/m 2 were more likely to reach the weight loss goal at 1 year. Metabolic procedures were also more successful than purely restrictive ones. Only 8% of patients achieved this goal when their preoperative BMI 4 50 kg/ m 2 . Policies and practice patterns that delay bariatric surgery until the BMI is highly elevated can result in inferior outcomes, although morbidity is unchanged. Patients should be counseled appropriately with respect to expectations after bariatric surgery.

Methods: The Longitudinal Assessment of Bariatric Surgery-2 is a 10-center observational study of adults who underwent bariatric surgery. Reproductive health was assessed among female partici- pants (N¼1931) pre-surgery and annually post-surgery for up to 7 years. This report was restricted to women 18-44 years old who reported no history of surgical or natural menopause, hysterectomy, or hormone replacement therapy.
