Composite unit written as a model document. Baselines, thresholds and data collection are bracketed as the author's own.
Measures
Each measure: definition; numerator and denominator; source; frequency; owner.
Outcome measures
1. Incident delirium. A first positive 4AT among patients 65 and older who screened negative on admission. Numerator: new positive screens. Denominator: patient-days among those negative on admission, per 100. Source: flowsheet. Weekly. Owner: author.
2. Sleep quality. Mean score on the Richards-Campbell Sleep Questionnaire, five items rated on 100-millimeter scales. Numerator: sum of scores. Denominator: questionnaires completed. Source: morning questionnaire at 0800, offered to patients able to complete it. Weekly. Owner: day charge nurse.
Process measures
3. Nursing-scheduled interruptions between 2300 and 0500. Numerator: timestamped tasks in the window. Denominator: eligible patient-nights. Source: electronic record. Weekly. Owner: author, with the quality analyst.
4. Checklist completion. Numerator: nights with a completed checklist. Denominator: eligible patient-nights sampled. Source: audit. Weekly. Owner: night charge nurse.
5. Sedative-hypnotic doses. Numerator: doses given. Denominator: patient-nights among patients 65 and older, per 100. Source: medication record. Weekly. Owner: pharmacist.
Balancing measures
6. Overnight rapid response calls, per 100 patient-nights.
7. Falls between 2300 and 0700, per 1,000 patient-days.
8. Medications given more than 60 minutes late between 2300 and 0700.
Why These Definitions
Incident delirium is measured only among patients who screened negative on admission, so delirium present on arrival is neither credited to nor blamed on the night protocol. The 4AT is used because it is brief and a meta-analysis found it accurate for delirium detection in older adults (Tieges et al., 2021).
Interruptions use timestamps rather than staff recall, a change traced to the progress report.
The Richards-Campbell Sleep Questionnaire was validated against polysomnography in critically ill patients (Richards et al., 2000), not in medical inpatients, and that limit will be stated wherever its results are reported. It is used because it is short enough for an older patient to complete at breakfast.
Design
A baseline of [56] nights before education is compared with a pilot of equal length after it. A pre-post comparison on one unit cannot prove that the protocol caused any change, because other things change over sixteen weeks too. Staffing, census, season and other projects may all affect the measures.
The plan therefore relies on run charts rather than a simple before-and-after average. Each measure is plotted weekly, with the baseline median drawn across the chart. Change is judged by rules set out for run charts in health care: six weekly points in a row all above the median or all below it, five points in a row that each climb or each fall, too many or too few runs, or a single point far beyond the rest (Perla et al., 2011). A signal by these rules suggests a change beyond ordinary variation; its absence suggests no reliable change, whatever the averages say.
Stopping Rule
The pilot pauses if [two] rapid response calls in the window are judged related to the protocol, meaning a patient deteriorated while asleep and would likely have been found sooner under usual care. Each overnight rapid response is reviewed within [48] hours by the night charge nurse and the clinical nurse specialist. A pause triggers a review of the exceptions list before the pilot resumes.
Reading the Measures Together
No single measure decides the result. The plan sets out in advance how combinations will be read:
Interruptions fall, delirium falls, balancing measures steady: the protocol is working as intended, and adoption is recommended.
Interruptions fall, delirium unchanged, balancing measures steady: the protocol achieved what nurses control, but not the outcome it hoped for. Given the evidence summary, this is the most likely result, and it still supports keeping the protocol for sleep and sedative reduction.
Interruptions unchanged: the protocol was not carried out as designed, and the checklist completion measure should show why.
Any balancing measure rises: the protocol is paused and reviewed, whatever the other measures show.
Writing these readings before the pilot prevents the team from choosing the story after seeing the data.
Sample Size
At a census of about [18] eligible patients a night, the pilot will include roughly [1,000] eligible patient-nights. That is enough to plot stable weekly points for interruptions and sedative doses. Incident delirium is rarer, and weekly points may be sparse; if fewer than [five] new cases occur in most weeks, delirium will be plotted monthly instead, a choice fixed now rather than after the fact.
Data Handling
Data are collected under the facility's quality improvement policy, stored on the unit's secure drive, and reported without patient identifiers. Collection itself is the author's to carry out once the quality department confirms the project's status.
Reporting
Results go back to night staff first, at a huddle and on the unit board, as run charts they can read at a glance. A written report to the practice council follows, following SQUIRE 2.0, whose reporting items ask for the context, the intervention, the measures, the results and their limits to be stated separately (Ogrinc et al., 2016).

How this NU480 Unit 7 example is structured
Definitions come first, because a measure that is not defined cannot be repeated. The plan then explains why incident delirium is measured only among patients who screened negative on admission, so that delirium present on arrival is neither credited to nor blamed on the night protocol. Interruptions use timestamps rather than staff recall, a change traced to the progress report. The design section is candid: a pre-post comparison on one unit cannot prove causation, so the plan relies on run-chart rules, a shift of six or more points on one side of the median or a trend of five, to judge whether change exceeds ordinary variation. Balancing measures and the stopping rule protect patients. Data handling follows facility quality improvement policy, with collection left to the author. Reporting results back to night staff, at a huddle and on the unit board, ends the plan.

Measures only make sense against objectives, which is why the objectives plan and any changes reported since are the starting point, along with the current assignment wording and rubric. A measures table, design rationale and run-chart rules follow within 24-48h, free the first time, and any data collection remains yours to carry out.

NU480 Unit 7 questions, answered
Does a BSN capstone evaluation need statistics?
Rarely in the inferential sense. Most quality improvement capstones use descriptive measures and run charts, which suit small samples and show change over time. The sample defines run-chart rules in advance so the reading is objective. If your course requires a particular analysis, send the instructions and the plan will follow them instead.
What is a balancing measure?
Think of it as a check on side effects: a figure tracked to catch harm the change could create somewhere else. A protocol that reduces night-time checks could, in principle, delay recognition of a patient getting worse, so the sample tracks overnight rapid response calls, falls and delayed medications. Including one or two balancing measures usually strengthens an evaluation plan considerably.
Can I evaluate a project I will not finish implementing this term?
Yes. Many capstones end with a plan rather than results, and instructors understand that. Write the evaluation as it would run, define the measures and the timeline, and be clear about what has and has not happened. The sample presents its design as ready to use without claiming any data exist yet.
