Slot offered — first YES wins
CaseFlow sends a single SMS to the top-ranked patient: "An OR slot just opened on [date]. Want it? Reply YES." If they say yes, the slot is theirs. If they don't respond within the window, CaseFlow moves to the next candidate — automatically, until the slot is filled.
First YES wins. Everyone else gets a "the slot was filled but you're still on the list for next time" auto-reply. Your staff sees the fill logged in their dashboard. No manual calls, no confusion, no missed revenue.
