Steps
Clinician identifies a care gap for one patient — suspects others have the same gap
A 38-year-old woman with dysfunctional uterine bleeding has not had tissue sampling ordered. The nurse clinician recalls two similar recent cases — but can't name them.
Q-Man query returns the cohort in minutes
Using PCC Query (Q-Man), the clinician enters criteria: diagnosis, missing order type, date range. Within minutes: two patients identified who need tissue sampling. The care gap becomes an actionable list.
Domain Pattern: Population Query at Point of Care
Population health queries available to clinicians at the point of care — not just to administrators or analysts. Q-Man is a proto-population-health tool: define criteria, find a cohort, act. Modern equivalent: care gap lists, risk stratification dashboards, panel management tools. The key insight is that the same data used for individual care should also be queryable across the population.
