Cost-Effectiveness of Laparoscopic and Open Pediatric Inguinal Hernia Repair.

Laparoscopic inguinal hernia (IH) repair is an alternative to open surgery. A potential advantage of laparoscopic repair is prevention of contralateral metachronous hernia although some studies report higher recurrence rate. We aim to determine the cost-effectiveness of open versus laparoscopic IH repair taking into account metachronous and recurrence rates.

The Safer Delivery of Surgical Services Program (S3): Explaining Its Differential Effectiveness and Exploring Implications for Improving Quality in Complex Systems.

Objective: To analyze the challenges encountered during surgical quality improvement interventions, and explain the relative success of different intervention strategies.

Summary Background Data: Understanding why and how interventions work is vital for developing improvement science. The S3 Program of studies tested whether combining interventions addressing culture and system was more likely to result in improvement than either approach alone.
