Surgical Drainage Meta-Analysis

Methodology: Meta-analysis
Client affiliation: Aesthetic and Plastic Surgery Institute, University of California, Irvine

Surgeons routinely use prophylactic drainage after surgery however this practice is often disliked by patients and the benefits are not always clear. Recently surgeons have been explicitly testing the value of drainage in specific surgical proceedures. The objective of this project is to determine the evidence-based value of prophylactic drainage in surgeries where drainage is above the fascia and below subcutaneous tissue. We are performing a meta-analysis of existing studies involving these kinds of drainage to characterize the drain effectiveness using a random-effects model considering possible outcomes such as hematomas, abscesses, seromas and or infections.
