To compare among surgeons the risk-adjusted rates of wound infection and incisional hernia after midline incisions. ⋯ The suture technique, monitored by the SL:WL ratio, is the most important factor for variability in the incidence of incisional hernia among surgeons in continuously sutured midline incisions. The suture technique may also help to explain the variability in rates of wound infection.
