Evaluation The fifth phase of the nursing process: judging whether expected outcomes were achieved. Full entry → is the fifth phase of the nursing process: determining whether the expected outcomes were achieved and whether the plan of care worked. It answers the question the planning phase set up: Did the patient get where we agreed they would go? The nurse compares the patient's actual response to the measurable expected outcomes written during planning, judges each outcome as met, partially met, or not met, and uses those judgments to decide what happens next — continue, modify, or discontinue parts of the plan.
Evaluation is not a single event at discharge. It is ongoing (done during every encounter, whenever the nurse checks whether an intervention is working) and terminal (a fuller evaluation at discharge or transfer). The nurse also evaluates the quality of the care itself — whether the care delivered was appropriate and effective, not just whether a checklist was completed. Whatever the finding, evaluation feeds back into the nursing process: unmet outcomes send the nurse back to assessment and planning to revise. Evaluation is what makes the nursing process a process — a cycle — rather than a one-way line.
Why this matters
- It closes the loop. Without evaluation, the nurse never finds out whether care worked, and the cycle cannot restart with better data.
- It protects the patient. Ongoing evaluation Checking outcome achievement during every care encounter. Full entry → catches interventions that are not working (or are causing problems) early, so they can be changed instead of continued out of habit.
- It makes care accountable. Evaluating against pre-written outcomes is objective and patient-centered — success is defined in advance, not decided after the fact.
- It is the foundation of Quality improvement Systematic efforts to improve care based on evaluation data. Full entry →. Patterns of unmet outcomes signal system-level problems, not just individual ones.
- Documentation of evaluation is legally and professionally required — the record must show not only what was done but whether it worked.
- Exam relevance. Distinguishing evaluation from assessment, and knowing what "Met / partially met / not met The three judgments of outcome achievement. Full entry →" means, are standard test items.

Core Concepts
Evaluation vs. assessment
Assessment and evaluation use the same tools — observation, interviewing, physical examination — but they serve different purposes. Assessment gathers data to understand the patient's current status and identify problems; it happens before and during care. Evaluation compares data against the expected outcomes written in the plan to judge success; it happens after (and during) implementation. The same vital sign measurement can be an assessment (baseline data) in one moment and an evaluation (does this outcome criterion hold?) in the next. The key difference is the yardstick: evaluation always has a pre-written outcome to measure against. No outcome, no evaluation — which is why measurable outcomes in the planning phase are non-negotiable.
Determining goal achievement
For each Expected outcome The measurable, time-limited criterion written during planning. Full entry →, the nurse makes a judgment using evidence gathered from the patient:
- Met: the patient's response meets the outcome criterion within the stated time frame.
- Partially met: some progress occurred, but the criterion was not fully achieved.
- Not met: no progress, or the patient's condition moved away from the outcome.
The judgment is based on observable evidence — what the patient says, does, or demonstrates; measurements; and records — not on the nurse's impression of effort. Evaluation is collaborative: the patient's own report of progress and the family's observations count as data, and the patient and family should be part of deciding what "good enough" looks like when outcomes are revised.
Analyzing why outcomes were not met
An unmet outcome is a starting point for analysis, not an accusation. The nurse asks: Did the patient's condition change? Was the diagnosis accurate? Was the intervention actually implemented as planned, and was it appropriate? Was the outcome realistic? Were there barriers — resources, readiness, understanding, social circumstances? The point is to identify what to change — the intervention, the outcome, the diagnosis, or the timing. Blaming the patient for "failing" an outcome is both wrong and clinically useless; the plan exists to serve the patient, and the plan is what gets revised.
Revising the plan: the four decisions
Evaluation results drive one of four plan revisions, and the nurse documents the reasoning:
- Continue: the outcome is being met or progress is on track; keep going.
- Modify: change the interventions, the outcome criteria, or the time frame based on the analysis.
- Discontinue: the outcome is resolved or no longer relevant; remove it from the plan.
- Restart: a problem that had resolved has returned; re-enter the nursing process for it.
Revision is a sign the process is working, not a sign of failure. Every revision begins with fresh assessment data, which may produce a new or changed diagnosis — the cycle continues.
Evaluating quality of care
Beyond individual patient outcomes, nurses evaluate whether the care was delivered well. A widely taught framework looks at three dimensions: structure (the resources and setting — staffing, equipment, environment), process (how care is delivered — adherence to standards, communication, documentation), and outcome (the results for patients). Nurses contribute to quality evaluation through chart reviews, incident and near-miss reporting, patient feedback, and unit-based quality improvement work — all according to facility policy. The goal is to improve systems, not to assign blame.
Common Confusions
| Do Not Confuse | With | Difference |
|---|---|---|
| Evaluation | Assessment | Assessment gathers data about current status; evaluation compares data to pre-written outcomes to judge success. |
| "Outcome not met" | "The patient failed" | Unmet outcomes are analyzed for causes in the plan, intervention, timing, or context — never treated as patient failure. |
| Terminal evaluation | The only evaluation | Ongoing evaluation happens at every encounter; terminal evaluation at discharge/transfer is the summary, not the whole story. |
| Documenting the intervention | Documenting the evaluation | The record must show what was done and whether it worked — the patient's response and the outcome judgment. |
| Revising the plan | Starting over | Revision continues, modifies, discontinues, or restarts specific parts using fresh assessment data — the cycle continues. |
| Evaluating the patient | Evaluating the care | Nurses evaluate outcomes and the quality of care (structure, process, outcome) through reporting and improvement activities. |
Eli explains
The same idea, in plain words
Explain it like I’m 10
Evaluation is like checking your homework against the answer key. Before you started, you wrote down what "done right" looks like. When you finish, you look at what you actually got and compare: right answer, halfway there, or wrong. If it's wrong, you don't just stare at it — you figure out what went wrong and redo that part. And you keep checking as you go, not just at the very end, so you catch mistakes while there's still time to fix them.
Worked example
Mr. L., who has a new diagnosis of diabetes, has this expected outcome in his plan: "By discharge, the patient will verbalize how to check his blood glucose and demonstrate the technique on himself without prompting." (Illustrative outcome for learning the evaluation role — not a clinical protocol.)
On day two, the nurse asks Mr. L. to walk through the steps. He can explain why checking matters and can describe the equipment, but he hesitates and makes two errors when actually demonstrating. The nurse judges the outcome partially met — and documents exactly what was observed: verbal steps correct, demonstration incomplete.
Instead of marking it "not met" and moving on, the nurse analyzes: Is the outcome realistic for the time frame? Is the teaching approach right for how Mr. L. learns? Mr. L. says he learns better by doing than by watching. The nurse modifies the plan — more hands-on practice with the nurse present, followed by a repeat demonstration — and sets a new review time. The outcome was not a verdict on Mr. L.; it was data that the plan needed changing. That analysis-and-revise cycle is the nurse's role in evaluation made visible.
Key takeaways
- Evaluation judges success against pre-written expected outcomes — met, partially met, or not met.
- Evaluation ≠ assessment. Assessment builds a picture of current status; evaluation compares that picture to outcome criteria. The yardstick is the difference.
- Evaluation is ongoing and terminal — every encounter and at discharge/transfer, not just the end of a stay.
- Evidence, not impression: judgments come from what the patient says, does, demonstrates, and measures show.
- Unmet outcomes trigger analysis, not blame — patient, plan, intervention, and context all get examined.
- Four revision decisions: continue, modify, discontinue, restart — each documented, each restarting the cycle with fresh assessment.
- Nurses evaluate quality of care too — structure, process, and outcome — through reporting and improvement activities per facility policy.
- Document the evaluation, including the patient's response, or the judgment has no record to stand on.

6 review questions from the chapter. Try each one, then open the answer.
What is the difference between evaluation and assessment?
Show answer
Assessment gathers data to understand current status; evaluation compares data against the expected outcomes written during planning to judge whether care worked.
What are the three possible judgments for an expected outcome, and what does each mean?
Show answer
Met (the patient's response meets the criterion in the time frame), partially met (some progress but not the full criterion), and not met (no progress or movement away from the outcome).
Why is ongoing evaluation important, rather than waiting until discharge?
Show answer
Because ongoing evaluation catches interventions that are not working — or are causing problems — while they can still be changed, rather than discovering failure only at the end of the stay.
A patient's outcome is "not met." What should the nurse do next, and why is analysis rather than blame the right response?
Show answer
Analyze why: patient condition changes, inaccurate diagnosis, intervention not implemented as planned, unrealistic outcome, or barriers such as resources and readiness — then revise the plan (modify, continue with changes, or restart) using fresh assessment data.
Name the four plan-revision decisions and when each is used.
Show answer
Continue (progress on track), modify (change interventions, criteria, or timing), discontinue (resolved or irrelevant), restart (problem has returned).
What does "structure, process, outcome" refer to, and why does it matter for nurses?
Show answer
It is a framework for evaluating quality of care — resources/setting (structure), how care is delivered (process), and results (outcome) — and it underlies nurses' participation in quality improvement and safety reporting.
