Dr Wendy Weller and colleagues from New York identified 7868 adults undergoing a bariatric procedure in 2003.
The team accessed the New York State's inpatient discharge database.
The research team constructed a multiple logistic regression model to examine the relationship between surgeon and hospital volume.
The team also assessed readmission after 30 days of discharge for bariatric operation.
The researchers controlled for demographics, comorbidity, and length of index hospitalization.
Among patients undergoing bariatric operation, 7% were readmitted within 30 days of discharge after their operation.

The most common readmission diagnosis was digestive system complications of surgical care.
The researchers showed that both surgeon and hospital volume were significantly associated with short-term readmissions.
Patients operated on by a low-volume surgeon were more likely to be readmitted as compared with those operated on by a medium-volume surgeon.
The team noted that patients operated on by high-volume surgeons were also more likely to be readmitted vs those operated on by medium-volume surgeons.
Patients in each of the lower hospital volume categories were more likely to be readmitted compared with the highest volume category.
Dr Weller's team concludes, “There is an important relationship between surgeon and hospital volume and short-term readmission after bariatric operation.”
