headline: Can AI assist in reducing diagnostic error? A narrative review
dek: Diagnostic error, defined as missed, wrong, or delayed diagnoses or those not communicated to patients, is common, affecting 5-10 % of hospital admissions and clinic visits. Such errors cause patient harm in up to 1 in 100 of such encounters and account for 10 % of all hospital deaths and serious adverse events. About 80 % of diagnostic errors are potentially preventable, most resulting from flaws in clinician reasoning in formulating and testing diagnostic hypotheses. The advent of artificial intelligence (AI),…
gain_title: AI and large language models have matured to improve clinicians' diagnostic decision-making during bedside and clinic consultations and help institutions increase diagnostic safety, addressing preventable diagnostic errors.

gain_reading: AI and large language models have matured to improve clinicians' diagnostic decision-making during bedside and clinic consultations and help institutions increase diagnostic safety, addressing preventable diagnostic errors.
gain_evidence: AI tools have matured to the extent that they can improve diagnostic decision-making of clinicians and can assist institutions in increasing diagnostic safety | About 80 % of diagnostic errors are potentially preventable, most resulting from flaws in clinician reasoning in formulating and testing diagnostic hypotheses

quick_read: A July 2026 narrative review in Diagnosis examined whether artificial intelligence and large language models can reduce diagnostic error in bedside and clinic consultations. It summarized evidence that diagnostic errors affect 5-10% of admissions and visits and contribute to patient harm and hospital mortality.

The authors concluded that AI tools have matured enough to improve clinician decision-making and help institutions increase diagnostic safety, while emphasizing that LLMs should complement rather than replace clinician reasoning and that evolving models require continuous monitoring.
limitation: Rapid LLM iteration means diagnostic capabilities are not stable and require ongoing evaluation.
tag: Evidence-backed gain
key_points: Diagnostic error affects 5-10% of hospital admissions and clinic visits and accounts for 10% of hospital deaths and serious adverse events. | About 80% of diagnostic errors are potentially preventable and stem from flaws in clinician reasoning in formulating and testing hypotheses. | Review examined AI and LLMs specifically within clinician-patient encounters at bedside or clinic.
rundown: The review frames diagnostic error as missed, wrong, delayed, or uncommunicated diagnoses, common in hospital and clinic settings, causing harm in up to 1 in 100 encounters. It attributes most preventable errors to clinician reasoning flaws.

It evaluates contemporary state-of-the-art research on AI and LLMs to answer seven clinician-relevant questions about adoption, concluding LLMs should complement rather than replace nuanced clinician reasoning.
