# Effectiveness review

> An effectiveness review checks that a fix worked and the problem did not return. A measure and a date set in advance let the action close.

Also known as: effectiveness check, effectiveness verification

## What it checks

CMS expects providers to measure success after they act and to track results so gains last (42 CFR 483.75(d)(1), 482.21(c)(3)). Nursing home governing bodies must make sure fixes are judged for effect (483.75(f)(5)). So must surgery center governing bodies (416.43(e)(2)).

The Joint Commission asks for system-wide improvement with measurable results. The VA gives each action a measure. A process measure shows the action was done. An outcome measure shows whether it worked.

## How to do it

1. Set the measure with the action, like falls with injury per 1,000 resident days.
2. Set a review date far enough out to see a trend.
3. Collect data and compare it to the baseline, the starting numbers.
4. Decide: effective, partly effective or not effective. Reopen the action if it failed.
5. File the proof so a surveyor can see it.

CMS also expects an acceptable [plan of correction](https://incidentkit.ai/glossary/plan-of-correction) to say how the facility will monitor results so fixes last. Mix-up: finishing the task is not the review. Installing alarms shows it was done. Fewer falls shows it worked.

## Frequently asked questions

### How long after implementation should the review happen?

CMS sets no number of days. Pick a window long enough to show a trend, and record the baseline.

### What counts as evidence of effectiveness?

Data tied to your measure: event rates before and after, audit results, or watching the new process in use. Keep both process and outcome measures.

### What if the action did not work?

Reopen it. Go back to the causes, choose a stronger action and set a new review date. Recording the failed try shows the system learns.
