Brief Summary

Post-surgical (bacterial) infections are the most frequent post-surgical complications, including deep or superficial wound infections, urinary tract infections, pneumonia, and even sepsis. Approximately 6.5-25% of all surgical patients will develop any type of bacterial infection. To personalize surgical infection management, (Artificial Intelligence) models are in the making to predict which patients are at high or low risk of developing a post-surgical infection. In order to benchmark these prediction models to the predictive capabilities of surgeons, the investigators aim to investigate the performance of surgeons in predicting the risk of a patient developing (any type) of post-surgical infection within 30 days.

Outcome Measures

Primary Outcomes (2)

  • The discriminative predictive performance of surgeons with respect to estimating the risk of developing (any type) bacterial post-surgical within 30 days of surgery

    The primary outcome measure of discrimination are area under the receiving operating characteristic curve (AUROC). Predictions are compared to the occurrence of a postoperative infection requiring treatment, surgical intervention or registration within 30 days of surgery.

    30 days

  • The calibration properties of surgeons with respect to estimating the risk of developing (any type) bacterial post-surgical within 30 days of surgery

    Calibration plots with slope and intercept

    30 days

Secondary Outcomes (5)

  • Relationship between the certainty in estimate and the predictive performance of surgeons

    30 days

  • Relationship between patient factors and predicted risk

    30 days

  • Predictive performance per surgeons and patients subgroups

    30 days

  • Relationship between predicted risk of surgeons and if they perform additional actions

    30 days

  • Comparison between the predicted risk of surgeons and an artificial intelligence algorithm

    30 days

Study Arms (1)

Surgeons estimate of postoperative infection

All surgeons will be asked to fill in a questionnaire, containing 5 questions, pertaining to the estimated risk of postoperative infection (within 30days). Thus there is a single arm and no comparison.

Behavioral: Questionnaire

Interventions

QuestionnaireBEHAVIORAL

Surgeons will be asked to fill in a short questionnaire after surgery on risk of postoperative infection
