The three shapes
Reference and knowledge content. Consulted deliberately by a clinician. Bought as a subscription, evaluated on coverage, currency, editorial process, and in-workflow accessibility. Governance load is light.
Rules-based alerting. Deterministic logic inside the record: interactions, allergies, dosing, care gaps. Evaluated on alert burden as much as on correctness, because an alerting layer that fires too often produces override behavior that degrades the whole system.
Predictive models. Score risk or likelihood without being asked. Evaluated as clinical AI: validation population, performance at local prevalence, subgroup behavior, monitoring, and accountable ownership.
Start with what you already have
The most common finding when a health system begins governing this category is that it already runs predictive models it had not catalogued, shipped inside the electronic health record or inside purchased clinical systems.
That is not negligence, it is how the software arrived. But it does mean the first question in this category is usually an inventory question rather than a purchasing one, and it frequently changes what the organization decides to buy.
Alert burden is the recurring failure
Decision support has a long, documented history of degrading through volume. Alerts that fire too frequently get dismissed reflexively, including the ones that mattered.
The practical implication for evaluation is that override rate belongs in the monitoring plan from day one, alongside technical performance. A model performing exactly as validated while being dismissed ninety percent of the time is delivering nothing, and only one of those two facts appears on a performance dashboard.
Who buys it
Reference content: CMIO, chief medical officer, library and knowledge services, pharmacy leadership. Alerting: clinical informatics and the specialty owning the rule. Predictive models: clinical informatics, analytics or data science leadership, quality and safety, and the AI governance body where one exists.
Who provides it
Structured profiles are in the clinical decision support vendor directory. Note that the directory includes electronic health record vendors in this category deliberately, because for many organizations the first predictive models in use arrived that way rather than as a separate purchase.
