Physician preference is a major factor in management of vesicoureteral reflux

Known factors affecting the management of vesicoureteral reflux (VUR) include reflux grade, infection frequency, age and gender. We hypothesized that provider preference is highly associated with management.

Utilizing the national billing database, Faculty Practice Solutions Center, a multivariable logistic regression model, was applied to analyze the association of pediatric urologist treatment patterns, patient age, gender, uni- or bilateral disease, insurance type, presence of nephropathy and race with the type of VUR treatment a patient would receive.

We identified 59 pediatric urologists who managed 7,882 new reflux patients from 2009 to 2011. Over this 3-year period there was wide variation in surgical utilization between surgeons (mean 50 %) but minimal change for each surgeon (5 %). For every 100 new reflux patients, median utilization of reimplantation surgery and injection of dextranomer/hyaluronic acid copolymer (Deflux) was 26 and 20 %, respectively. Age ranked highest in predicting surgical versus non-surgical management, while a surgeon's historic Deflux utilization rate ranked highest in predicting surgery type. Older age, female gender and white race also increased the odds of Deflux utilization over reimplantation.

A surgeon's historic Deflux utilization was the most important predictor of VUR surgery type. Although data on reflux grade were not available, analysis of patient and surgeon characteristics suggests that surgeon preference is the first or second most critical factor in determining a patient's treatment.
