Abstract

BACKGROUND:

It is well documented that bariatric surgery is an effective weight loss intervention, and bariatric procedure rates have increased over time. However, there was a period of plateau in procedure rates in the mid to late 2000s. Recent literature has not identified current trends in procedure rates or associations between bariatric surgery and population factors, such as obesity and diabetes.

OBJECTIVES:

The purpose of this study was to determine trends in statewide rates of bariatric operations, obesity, and diabetes over an 11-year period and to determine if population factors are associated with procedure rates.

SETTING:

Data from the Agency for Healthcare Research and Quality (AHRQ) Healthcare Cost and Utilization Project (HCUP) State Inpatient Database (SID) were utilized to identify a study sample population of patients who underwent bariatric procedures from 2002-2012.

METHODS:

State level population characteristics were obtained from the Behavioral Risk Factor Surveillance System and Census Bureau Data for the 11-year period. Statistical analyses determined rates of surgery, obesity, and diabetes over time, as well as associations between surgery rates and population factors.

RESULTS:

From 2002-2012, bariatric procedure rates increased, with an exponential rise in laparoscopic surgical methods. Procedure rates reached a peak value in 2009 and then plateaued. Statewide obesity and diabetes rates increased over time, although there was no association between these population factors and procedure rates. Women had consistently higher rates of bariatric operations.

CONCLUSION:

Although bariatric procedures are an evidenced-based effective treatment for obesity, procedure rates were not associated with the increasing obesity and diabetes rates in the United States. Further research is needed to identify factors that affect the adoption and diffusion of bariatric operations to increase diffusion of beneficial innovations and improve overall quality of care and health outcomes.
