The net benefit of the intraoperative prevention
strategy was $14.11 for patients with a surgical
duration of 90 min and increased with greater
surgical duration, suggesting that prevention
was cost effective for surgical duration $90 min
(Fig 2). At a surgical duration of 90 min, the
projected intraoperative incidence ranged from
0.1% to 0.9%; the corresponding net benefit of
prevention ranged from $3.46 to $37.10. The intraoperative
prevention strategy remained cost effective
for patients even at low intraoperative risk.
