    Periscope will automatically identify when your patient fits the inclusion criteria for these surveys.

    The STOP-BANG questionnaire is a concise and easy-to-use screening tool for OSA. It has been developed and validated in surgical patients at preoperative clinics.

    Score OSA Risk
    0-2 Low
    2-4 Intermediate
    ≥ 5 High
    ≥ 2 STOP criteria
    and
    ≥ 1 BNG criteria

    The Revised Cardiac Risk Index (RCRI) was originally published by Goldman et al. (1977), though the original publication is widely understood to have under-estimated 30-day MACE risk. A more modern meta-analysis by Duceppe et al. (2017) has provided updated risk estimates:

    Score 30-day MACE Risk
    0 3.9% (2.8-5.4%)
    1 6.0% (4.9-7.4%)
    2 10.1% (8.1-12.6%)
    ≥ 3 15% (11.1-20.0%)

    The Apfel score is a simplified risk score for PONV that uses four independent predictors: female gender, history of motion sickness or PONV, non-smoking status, and expected use of postoperative opioids.

    The Surgical Outcome Risk Tool (SORT) is designed to estimate 30-day mortality after inpatient surgery.

    Avoid using the SORT score for outpatient surgery (i.e. day cases and simple overnight admissions).

    It was created using 16,788 cases from the NCEPOD database and later validated by Wong et al. against 22,631 cases from Australia, New Zealand, and the United Kinddom.
