    Common causes of dataset shift can be grouped into changes in technology, changes in population and setting, and changes in behavior.

Claims other papers make about this one

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

  • Variations in patient demographics, clinical practices, and data collection procedures can lead to inaccurate predictions when predictive models are deployed across different hospitals or healthcare systems.

    “This quality becomes crucial when predictive models are deployed across different hospitals or healthcare systems, where variations in patient demographics, clinical practices, and data collection procedures can lead to inaccurate predictions [17, 18].”

    From Toward generalizable and interpretable machine learning models in healthcare: Insights from ICU outcome predictions (2026) · cites this paper as [18]

    In “To the Editor” (page unavailable), the paper says dataset shift can make a clinical AI system underperform when deployment data differ from development data. It identifies changing patient demographics and clinical behavior or practice as potential causes, and describes a hospital sepsis model producing spurious alerts. Our copy does not specifically identify differences in data-collection procedures as a cause. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Small changes in data distribution between training and clinical evaluation populations (dataset shift) can lead to substantial variation in clinical performance and expose patients to potential unexpected harm.

    “Small changes in the distribution of the underlying data between the algorithm training and clinical evaluation populations (i.e., dataset shift) can lead to substantial variation in clinical performance and expose patients to potential unexpected harm [21, 22].”

    From Use of artificial intelligence in critical care: opportunities and obstacles (2024) · cites this paper as [21]

    The 'TO THE EDITOR' section defines dataset shift as a development-to-deployment data mismatch that causes underperformance, and describes a sepsis-alert model deactivated after demographic changes caused spurious alerts. It also says some causes of shift are subtle and calls for AI safety oversight. It does not establish that small distribution changes cause substantial performance variation or describe patient harm, though such harm is framed as a potential risk in the claim. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Dataset shift in medicine is the rule rather than the exception, driven by changes in care delivery, clinical incentives, and documentation rather than by random variation alone.

    “Finlayson et al. argue that dataset shift in medicine is “the rule rather than the exception,” driven by changes in care delivery, clinical incentives, and documentation rather than by random variation alone [8].”

    From Validation is not enough: Longitudinal evidence of post-deployment fragility in clinical AI systems (2026) · cites this paper as [8]

    In the 'TO THE EDITOR' section (page not available), the paper describes dataset shift as a major driver of clinical AI malfunction and lists common causes, including changes in behavior such as reimbursement incentives. It does not say that dataset shift is 'the rule rather than the exception' or specifically identify documentation changes as a cause. (LLM, conf=0.86)

  • Between 3 and 4 weeks after its first COVID-19 hospitalization, the University of Michigan paused ESM-generated alerts in April 2020 after nursing reports of overalerting.

    “Between 3 and 4 weeks after its first COVID-19 hospitalization, the University of Michigan paused ESM-generated alerts in April 2020 after nursing reports of overalerting.5”

    From Quantification of Sepsis Model Alerts in 24 US Hospitals Before and During the COVID-19 Pandemic (2021) · cites this paper as [5]

    The “TO THE EDITOR” section says the University of Michigan Hospital deactivated Epic’s sepsis-alerting model in April 2020 because of spurious alerts during the COVID-19 pandemic. It does not give the interval since the hospital’s first COVID-19 hospitalization or say that nursing reports prompted the decision. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Clinicians who are well-prepared to recognize when AI tools are misbehaving are essential partners in safe deployment, and institutions need governance structures, monitoring protocols, and clear pathways for frontline staff to escalate concerns.

    “Finlayson et al 55 have argued that clinicians who are well-prepared to recognize when AI tools are misbehaving are essential partners in safe deployment, and that institutions need governance structures, monitoring protocols, and clear pathways for frontline staff to escalate concerns.”

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-11-02.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-11-02.

Cited sources are checked by gpt-6-sol.

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.
