Abstract

Background Major postoperative complications are associated with increased cost and mortality. The complexity of electronic health records overwhelms physicians' abilities to use the information for optimal and timely preoperative risk assessment. We hypothesized that data-driven, predictive-risk algorithms implemented in an intelligent decision-support platform simplify and augment physicians' risk assessments.Methods This prospective, nonrandomized pilot study of 20 physicians at a quaternary academic medical center compared the usability and accuracy of preoperative risk assessment between physicians and MySurgeryRisk, a validated, machine-learning algorithm, using a simulated workflow for the real-time, intelligent decision-support platform. We used area under the receiver operating characteristic curve to compare the accuracy of physicians' risk assessment for six postoperative complications before and after interaction with the algorithm for 150 clinical cases.Results The area under the receiver operating characteristic curve of the MySurgeryRisk algorithm ranged between 0.73 and 0.85 and was significantly better than physicians' initial risk assessments (area under the receiver operating characteristic curve between 0.47 and 0.69) for all postoperative complications except cardiovascular. After interaction with the algorithm, the physicians significantly improved their risk assessment for acute kidney injury and for an intensive care unit admission greater than 48 hours, resulting in a net improvement of reclassification of 12% and 16%, respectively. Physicians rated the algorithm as easy to use and useful.Conclusion Implementation of a validated, MySurgeryRisk computational algorithm for real-time predictive analytics with data derived from the electronic health records to augment physicians' decision-making is feasible and accepted by physicians. Early involvement of physicians as key stakeholders in both design and implementation of this technology will be crucial for its future success.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In a prospective study, an algorithm predicted postoperative complications with greater accuracy than physicians.

    “In a prospective study, the algorithm predicted postoperative complications with greater accuracy than physicians.17”

    From Artificial Intelligence and Surgical Decision-making. (2020) · cites this paper as [17]

    The Methods describe a prospective pilot study using a simulated workflow. The Results report that MySurgeryRisk was more accurate than physicians’ initial assessments for the postoperative complications tested except cardiovascular complications. The claim omits that exception and the simulated-workflow setting. (LLM, conf=0.88)

    Experimental — accuracy not yet measured

  • Individuals who lean toward analytical thinking, which may be associated with high need for cognition, are more likely to change decisions after interacting with an algorithm.

    “Brennan et al [ 65 ] found that individuals who lean toward analytical thinking, which may be associated with a high need for cognition, exhibited a higher likelihood of changing their decisions after interacting with an algorithm.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
