Abstract

Uncertainty estimation in healthcare involves quantifying and understanding the inherent uncertainty or variability associated with medical predictions, diagnoses, and treatment outcomes. In this era of Artificial Intelligence (AI) models, uncertainty estimation becomes vital to ensure safe decision-making in the medical field. Therefore, this review focuses on the application of uncertainty techniques to machine and deep learning models in healthcare. A systematic literature review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Our analysis revealed that Bayesian methods were the predominant technique for uncertainty quantification in machine learning models, with Fuzzy systems being the second most used approach. Regarding deep learning models, Bayesian methods emerged as the most prevalent approach, finding application in nearly all aspects of medical imaging. Most of the studies reported in this paper focused on medical images, highlighting the prevalent application of uncertainty quantification techniques using deep learning models compared to machine learning models. Interestingly, we observed a scarcity of studies applying uncertainty quantification to physiological signals. Thus, future research on uncertainty quantification should prioritize investigating the application of these techniques to physiological signals. Overall, our review highlights the significance of integrating uncertainty techniques in healthcare applications of machine learning and deep learning models. This can provide valuable insights and practical solutions to manage uncertainty in real-world medical data, ultimately improving the accuracy and reliability of medical diagnoses and treatment recommendations.

  • Healthcare providers who use AI may be integrating inaccurate data into the decision-making process.

    “Therefore, healthcare providers who use AI, may be integrating inaccurate data into the decision-making process (Seoni, 2023).”

    From Procedure to Evaluate Artificial Intelligence (AI) Output for Educational and Clinical Tasks (2026) · cites this paper as Seoni, 2023

    The Discussion (p. 14) warns that AI model decisions may be unreliable and that uncertainty estimates are needed for safe medical decision-making. The Conclusion (p. 19) also discusses reducing misclassifications. These passages support a risk of inaccurate AI outputs affecting decisions, but do not specifically say that providers integrate inaccurate data into their decision-making. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Predictive AI models are not clear and may be based on highly variable data, including inaccurate diagnoses, errors with data entry, and inconsistencies in how healthcare measurements are derived and reported.

    “Finally, the predictive AI models are not clear and may be based on highly variable data, including inaccurate diagnoses, errors with data entry, and inconsistencies with how healthcare measurements are derived and reported based on human variability (e.g., blood pressure, heart rate, etc.; Seoni, 2023).”

    From Procedure to Evaluate Artificial Intelligence (AI) Output for Educational and Clinical Tasks (2026) · cites this paper as Seoni, 2023

    The Introduction (p. 3) says predictive AI uncertainty can arise from flawed models and from incomplete, noisy, or conflicting data. The review also describes inter-observer variability in assessing cardiovascular images (Section 3.2.1, p. 9). These passages support the general concern, but they do not substantiate the cited sentence’s specific examples of inaccurate diagnoses, data-entry errors, or human variability in blood-pressure and heart-rate measurements. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Lack of transparency in how AI identifies and synthesizes information introduces potential biases into clinical decision-making and distrust.

    “This introduces potential biases into the clinical decision-making process and distrust with lack of transparency in this process (Nilsen et al., 2024;Seoni, 2023).”

    From Procedure to Evaluate Artificial Intelligence (AI) Output for Educational and Clinical Tasks (2026) · cites this paper as Seoni, 2023

    The Discussion (p. 14) says explainability alone cannot guarantee reliable model decisions and recommends uncertainty estimates for safe medical decision-making. The Conclusion (p. 19) also addresses AI reliability and safety, but neither passage says that lack of transparency introduces bias into clinical decisions or causes distrust; searches for those terms found no supporting passage.

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.
