Key result
Surgeons and anesthesiologists significantly misjudge intraoperative blood loss during hip fracture surgery.
Why the study?
The accuracy of intraoperative blood loss estimation by orthopaedic surgeons and anaesthesiologists during hip fracture surgery as part of the Surgical Safety Checklist was unclear.
How accurately do orthopaedic surgeons and anaesthesiologists estimate intraoperative blood loss during hip fracture surgery?
Observational (n=55)
How accurately do orthopaedic surgeons and anaesthesiologists estimate intraoperative blood loss during hip fracture surgery?
p-value: p=<0.001
Surgeons and anaesthesiologists inaccurately estimate intraoperative blood loss during hip fracture surgery, suggesting that asking if excessive blood loss is expected may be more useful for the Surgical Safety Checklist.
Estimates of blood loss warrant cautious interpretation in hip fracture surgery; this Level 3 cohort study leaves open whether checklist alternatives improve safety.
AIM: To assess how accurately orthopaedic surgeons and anaesthesiologists estimate intraoperative blood loss during hip fracture surgery as part of the Surgical Safety Checklist (SCC). METHODS: A prospective study of 55 operations over 9 months. Pre- and post-operative estimations of blood loss were documented. Actual blood loss was determined by subtracting total amount of lavage fluid used from overall volumes in the suction bag and by weighing used swabs. CONCLUSION: Rather than numerical estimates, a more useful question within the SSC may therefore be: "Is excessive blood loss expected?"

Budair et al. (2016) conducted an observational in Hip fracture (n=55). Estimation of intraoperative blood loss vs. Actual measured blood loss was evaluated on Accuracy of estimated intraoperative blood loss (p=<0.001). Numerical estimations of intraoperative blood loss by surgeons and anaesthesiologists during hip fracture surgery were significantly inaccurate (P<0.001).
