A PRN pool is a list of nurses who have said yes in principle. Turning that into covered shifts takes four things: the right people, their dates before the schedule is built, a call order, and an overtime check.
At a small hospital, the per diem nurse may be the one who covers the 5 a.m. callout. This guide reviews eight platforms on how they handle per diem availability, callout coverage, overtime tracking and credential verification.
Per diem nurses work shift by shift, with no set schedule and no benefits, in exchange for a higher hourly rate. For a critical access hospital, a ready pool of them is what stands between a 5 a.m. callout and an expensive agency invoice. This guide explains what per diem nursing is, how it compares to PRN and agency work, and how a small hospital builds a pool it can rely on.
