Abstract
BACKGROUND: Incisional hernias (IH) following abdominal surgery persist as morbid, costly, and multi-disciplinary surgical challenges. Using longitudinal, multi-state, administrative claims data (HCUP State Inpatient Databases (SID)); (HCUP State Ambulatory Surgery and Services Databases (SASD)), we aimed to characterize the epidemiology, outcomes, recurrence, and costs of IH. STUDY DESIGN: 529,108 patients undergoing abdominal surgery in 2010 across six specialties (colorectal, general/bariatric, hepatobiliary, obstetrics/gynecology, urology, and vascular) were identified within inpatient and ambulatory databases for Florida (FL), Iowa (IA), Nebraska (NE), New York (NY), and Utah (UT). IH repairs, complications, and expenditures were assessed through 2014. Predictive regression modeling was validated using a training set of 1000 bootstrapped repetitions. RESULTS: 16,169 (3.1%) patients developed hernias requiring repair (4.3-year mean follow-up), 3176 (20%) underwent recurrent repair, and 731 (23%) underwent re-recurrent repair. Patients with IH had increased readmissions (6.6 vs. 2.4), morbidity (39 vs. 8% surgical and 22 vs. 7% medical), and costs ($46,000 vs. $25,000) when compared to patients without IH (p < 0.001). IH expenditures totaled $875 million: initial ($687 million), recurrent ($155 million), and re-recurrent hernias ($33 million). IH predominated in colorectal (10%), hepatobiliary (8%), and vascular (5%) procedures. Of 31 significant independent IH risk factors (p < 0.001), obesity, age, smoking, open surgery, and prior surgery were pervasive across surgical specialties. CONCLUSION: IH represents an unremitting surgical epidemic associated with considerable morbidity, costs, and features consistent with a chronic disease state. We define critical pervasive risk factors (obesity, age, smoking open surgery, and prior surgery) independently associated with IH across surgical disciplines. With failed repairs, subsequent success becomes less likely, increasing morbidity and costs-underscoring the critical importance of optimal treatment and prevention.
