The Access Gap That Makes Bad Advice Acceptable
The condition driving AI health adoption is not enthusiasm — it is the comparative cost of the alternative. When 65% of patients report choosing AI because it is easier than reaching a provider, the tool's error rate becomes secondary to its availability. The Zocdoc AI-Informed Patient report on access barriers establishes this clearly: the AI consultation is not a preference, it is a workaround for a system that fails on scheduling, cost, and wait time before a clinical question is even asked.
What that creates institutionally is a two-tier risk environment. Patients with reliable access to care use AI as supplementary input. Patients without that access use it as primary guidance — and those are the patients for whom an 80% early-diagnosis error rate is not an abstract statistic but an operational reality. The health equity dimension of AI diagnostic failure is the part the conversation around accuracy has not caught up to: the tool is least reliable for the populations most dependent on it.
