title: Outcomes, health status, and medical resource utilization after bariatric surgery.
abstract: Surgical results, economic consequences, and shortterm health of obese patients were evaluated before and after bariatric surgery. Of 35 patients in Mayo Health Plan Arizona eligible for bariatric surgery and scheduled for gastric restriction with Roux-en-Y gastrojejunostomy, 22 (7 men, 15 women) completed pre- and postoperative (6- and 12-mo) short form (SF)-12 Health Surveys. Nineteen patients had open bariatric procedures and 3 had laparoscopic procedures. Comorbid conditions, hospital course, weight loss, and complications were examined. Health care utilization (actual dollars paid by plan) for the preceding year and at 1- and 2-yr follow-up were compared. Major comorbid conditions included diabetes mellitus or impaired fasting glucose, hyperlipidemia, sleep apnea, and hypertension. Mean length of hospital stay was 4.8 d after open procedures and 2 d after laparoscopic procedures. No serious operative or postoperative complications occurred. From a baseline average body mass index (BMI) of 51.9, the 6- and 12-mo BMI averages were 39.6 (23.7% decrease) and 35.3 (32% decrease), respectively. Both physical and mental status improved. From baseline, physical health changed 18 and 21.2 points at 6 and 12 mo, respectively (p < 0.001), and mental health changed 9.3 points at each interval (p =0.003). Each postoperative year, resource utilization decreased (mean= $1300 per patient). Our findings of good surgical outcomes, significant weight loss, improved health status, and potential financial savings in this small sample may help patients, insurers, and self-funded employer groups evaluate the appropriateness of bariatric procedures.
