Inpatient Cost of Trauma Care Versus Repair of Elective Open Inguinal Hernias: Nationwide Trends Over Nearly a Decade

Purpose: Concerns exist regarding increased trauma activation fees at the expense of vulnerable patients. In contrast, elective open inguinal hernia repair (E-OIHR) has remained relatively fixed in terms of technique. This study aimed to examine health care costs for E-OIHR and trauma patients, hypothesizing trauma cost would increase from 2010 to 2018, while E-OIHR cost would remain unchanged. Methods: The Nationwide Inpatient Sample database was queried (2010-2018) for admitted patients undergoing unilateral E-OIHR or trauma-related admission. Health care costs per admission, total annual costs, and trends of E-OIHR and trauma admissions were also examined. Multiple linear regression was used to estimate the association of individual- and hospital-level variables with total costs. Results: Unilateral E-OIHR admission cost more than doubled per case in 2018. Trauma cost per admission also increased, however, only by 34%. Total costs for all E-OIHR admissions increased 26%, whereas trauma admission costs increased 32%. Both trauma admissions and unilateral E-OIHR admissions decreased; however, E-OIHR admissions decreased more. Multiple linear regression demonstrated compared to the cost of E-OIHR, trauma care decreased when adjusting for year, age, severity, hospital type, and length of stay (P < .001). Conclusion: The rate of increase in cost per unilateral E-OIHR admission exceeded that of trauma. However, the total economic burden for trauma care increased by billions of dollars due to a steady increase in per incidence cost and only slightly lower rates of trauma admissions. Increased focus on high-value care to curtail increasing costs of E-OIHR and especially trauma appears warranted.
