Why do underwriters ask how much agency labor we use?

Agency percentage is a proxy for three things at once. It signals the labor market position of the facility, which correlates with everything else about operational stability. It signals continuity of care, since a resident cared for by a different person every shift has less chance of a change in condition being noticed. And it signals documentation quality, because agency staff are less familiar with your systems and your charting expectations.

None of that is a judgment about individual agency clinicians, many of whom are excellent. It is a statement about the structure, and underwriters price structure.

An agency nurse who makes an error creates exposure for the facility through several routes: the agency nurse may be found to be your borrowed servant, you may be liable for negligent selection or supervision, and the resident had no relationship with the agency at all.

Whether that exposure is transferred depends entirely on the contract and the certificate. The agency should carry its own professional liability at limits matching yours, name you as additional insured on a form covering your vicarious liability, provide primary and noncontributory wording, waive subrogation and indemnify you for its own negligence.

And the certificate must be current on the date of the incident, not on the date the relationship started. Expired agency certificates are one of the most common findings in this class, and an expired certificate means the exposure came back to you without anyone noticing.

In litigation, the agency staff who were on duty are frequently the key witnesses and are frequently unreachable, having moved to another agency and another state. That converts a defensible case into a documentary case, decided entirely by what was charted.

It also opens the corporate negligence theory: heavy agency use is presented as evidence that the operator could not staff the building, which supports the argument that the injury was the predictable result of a staffing decision.

The trend rather than the level. An underwriter looking at an agency percentage that has fallen over eight quarters is looking at a different risk from one looking at the same number rising.

The orientation process for agency staff, including what they are shown about care plans and charting before their first shift. The certificate tracking process with evidence it is current. And the retention initiatives behind the trend, since the durable answer to agency reliance is staff retention and underwriters know it.
