Abstract

BACKGROUND:

Bariatric surgery is the most effective treatment for obesity. Guidelines for optimizing postoperative care are emerging, and roles of the surgeon and registered dietician (RD) have opportunities for coordination.

OBJECTIVES:

The study objective was to better define the appropriate guidelines for postoperative care by investigating whether a combined surgeon and RD follow-up for the initial postoperative visit within 2 to 6 weeks after surgery improves patient outcomes.

SETTING:

The setting was an accredited bariatric hospital in an academic setting.

METHODS:

A retrospective analysis of a prospective database was performed on patients who underwent bariatric surgery and were followed up by either a surgeon alone or by a surgeon and RD for initial postoperative visit.

RESULTS:

There were 302 patients in the surgeon follow-up group and 268 in the RD follow-up. Patients in the RD follow-up group had significantly fewer readmissions due to dietary-related problems (9 versus 0; P = .004), more favorable 3-month change in serum thiamine (-30.5 versus-4.04; P = .002), high-density lipoprotein (-3.42 versus-1.67; P = .053), and triglycerides (-17.5 versus-31.5; P = .03), and trended lower number of minor complications (16 versus 6; P = .08). No significant differences in percent excess weight loss were observed at all time points after surgery. Multivariate logistic models controlling for demographic features found that RD follow-up predicted 3-month increase in thiamine (odds ratio = 2.49; P<.000) and high-density lipoprotein cholesterol (OR = 1.73; P = .01), and decrease in total cholesterol (OR = 1.58; P = .03) and triglycerides (OR = 1.55; P = .03).

CONCLUSIONS:

Follow-up with a surgeon and RD for the initial postoperative visit may help improve patient outcomes.
