Wloch C, Van Hoek AJ, Green N, et al. - Researchers investigated the economic burden to the health service of surgical site infection following cesarean section. Further, they investigated potential savings attainable through implementation of a surveillance program. Based on infection risk of 9.6%, the hospital carrying out 800 cesarean sections a year had costs (2010) estimated at £18,914 with 28% accounted for by community care (£5,370). With inflation to 2019 prices, this compares to an estimated cost of £5.0 m for all cesarean sections conducted annually in England 2018–2019, nearly £1,866 and £93 per infection treated in hospital and community, respectively. For one calendar quarter, hospital had estimated surveillance cost of £3,747 (2010 costs). Modelling a reduction in risk of infection of 30%, 20% or 10% between successive surveillance periods suggested that a variable intermittent surveillance strategy attained higher or similar net savings than continuous surveillance. Surveillance of surgical site infections after cesarean section with feedback of data to surgical teams provides a potentially effective means to decrease infection risk, improve patient experience and save money for the health service.
