NRS 497 Topic 7 DQ 2: evaluating an EBP project
Discuss one way you will be able to evaluate whether your evidence-based practice project made a difference in practice, given that evaluating a project means determining the effectiveness of the change.

One measure, chosen and defended
The word doing the work here is one. The prompt asks for a single way to evaluate the project, which means the post is graded on the quality of one choice and its defence rather than on breadth. So pick a measure and commit to it. The strongest choice is usually the outcome your PICOT question named, because a project that measured something else has quietly changed its own question: if the aim was cutting catheter-associated urinary tract infections, the measure is the CAUTI rate per thousand catheter-days, not satisfaction with the protocol. Say what type of measure you are using — outcome, process or balancing — and why that type answers whether practice changed. A process measure such as bundle compliance tells you the intervention happened; an outcome measure tells you it mattered; a balancing measure tells you it did not break something else. Naming which one you chose, and what it cannot tell you, is the analytic move assessors want.
Then make the measure operational, because an unmeasurable evaluation plan is the commonest failing. State the data source and who collects it — the electronic record, an audit tool, an existing quality dashboard, a validated instrument with its reliability reported — and the interval, since a single post-implementation number proves nothing. You need a comparison: baseline against post-implementation, a run chart or statistical process control chart over enough points to distinguish a real shift from ordinary variation, or a comparison unit. Say how you would know the change was due to the intervention rather than to seasonality, a concurrent initiative or the Hawthorne effect, and what result would make you conclude the project had simply not worked in this setting. A stated threshold for failure, fixed in advance rather than chosen once the numbers are in, is what turns an evaluation plan into a real test instead of a search for a flattering way to report it.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Select a single evaluation measure aligned to the project's PICOT outcome.
- 02Distinguish outcome, process and balancing measures.
- 03Operationalise a measure with a data source, collector and interval.
- 04Specify a comparison and a threshold that would falsify success.
Read the full question
Review every instruction before using the planning guidance that follows.
Turn the brief into deliverables
- 01One way to evaluate whether the project made a difference in practice.
- 02Why that measure follows from the project's own question.
- 03The type of measure and what it can and cannot show.
- 04The data source, collection method and interval.
- 05The comparison — baseline, control unit or control chart.
- 06What result would indicate the change was not effective.
From outcome to measurement to comparison
What evaluating effectiveness means
Distinguish did it happen from did it work.
Choosing the measure
Derive it from the PICOT outcome rather than from what is easy to collect.
Outcome, process or balancing
Name the type and say what it can and cannot demonstrate.
Making it measurable
Data source, collector, instrument and interval.
The comparison
Baseline versus post, run chart or control unit.
What would count as failure
A threshold, and the confounders that could fake success.

Review before submission
Common mistakes
- Listing several measures when the prompt asks for one.
- Measuring staff satisfaction as a proxy for a clinical outcome.
- Naming a measure with no data source or collection interval.
- Reporting a single post-implementation figure with no baseline.
- Ignoring confounders such as seasonality or a concurrent project.
- Defining no threshold at which the project would count as unsuccessful.
Submission checklist
- Exactly one evaluation approach is put forward and defended.
- It matches the outcome in the project's PICOT question.
- The measure type is named and its limits acknowledged.
- A data source and interval are specified.
- A comparison method is described.
- A failure threshold is stated.
