Usability Review of Documenting a Pain Reassessment After an Opioid Dose in the Inpatient Record
The Task and the User
Task: document a pain reassessment 30 to 60 minutes after giving an as-needed opioid, as hospital policy requires. The reassessment records the pain score, sedation level, respiratory rate, and the patient's response. User: a registered nurse with one to three years of experience on a medical-surgical unit, working on a workstation on wheels, who performs this task six to ten times per 12-hour shift. The review assumes the user is logged in and has the patient's record open. The system is the hospital's inpatient electronic health record as configured on this composite unit.
Heuristic Set and Severity Scale
Problems are rated against a named heuristic set that adapts Nielsen's usability heuristics for medical systems, including visibility of system state, match between system and world, consistency, minimizing memory load, informative feedback, error prevention, and minimalist design (Zhang et al., 2003). Severity is rated on the scale Nielsen (1994) described, defined here before any finding: 0, not a usability problem; 1, cosmetic, fix if time allows; 2, minor, low priority; 3, major, important to fix; 4, catastrophic, must fix before further use. A problem's severity reflects how often it occurs, its impact when it occurs, and whether users can work around it.
Walkthrough
Step 1: The nurse receives no prompt when the reassessment is due; the only cue is a small clock icon on the patient list that turns orange 60 minutes after the dose, visible only on the list view. Step 2: From the patient chart, the nurse opens the Flowsheets tab, then selects the Pain Assessment flowsheet group from a list of 23 groups. Step 3: The nurse scrolls horizontally to find the correct time column; the columns are in 15-minute intervals and the current time column is not highlighted. Step 4: The nurse enters the pain score, then must switch to a different flowsheet group, Neurological, to enter the sedation score. Step 5: The nurse switches to a third group, Vital Signs, to enter respiratory rate. Step 6: The nurse returns to the medication administration record to document the response to the medication in a free-text field linked to the dose. Step 7: The nurse files each flowsheet separately.
Counts: 22 clicks, 4 screens, and 3 horizontal scrolls in the median of five timed walkthroughs by the reviewer; median time, 2 minutes 40 seconds. Information requested in more than one place: the pain score is requested in the pain flowsheet and again, as free text, in the administration record response field. At eight reassessments a shift, the task alone accounts for about 20 minutes of documentation time, a scale of burden consistent with studies that have counted clicks per shift in hospital records (Hill et al., 2013).
Findings, One Per Problem
Each finding is tied to one heuristic and one severity rating.
| No. | Problem | Heuristic | Severity | Rationale |
|---|---|---|---|---|
| 1 | No active prompt when reassessment is due; only a small orange icon on the list view | Visibility of system state | 4 | Frequent, silent, and linked to missed monitoring after opioids |
| 2 | Pain score, sedation, and respiratory rate are on three separate flowsheet groups | Minimalist design; memory load | 3 | Every reassessment requires three screens; values can be split across time columns |
| 3 | Current time column not highlighted; horizontal scroll required | Visibility of system state | 3 | Entries in the wrong time column misstate when the reassessment happened |
| 4 | Pain score requested twice, in flowsheet and as free text in the administration record | Consistency; minimalist design | 2 | Duplicate entry; the two may disagree |
| 5 | Sedation scale options labeled with numbers only, without descriptors | Match between system and world | 3 | Nurses must remember what each number means on the scale in use |
| 6 | No feedback that the reassessment requirement has been met; orange icon persists until the next refresh | Informative feedback | 2 | Nurses reopen the chart to check, adding clicks |
Why the Highest-Severity Problem Matters Clinically
Problem 1 is rated catastrophic because opioid-induced respiratory depression usually develops after a dose, and the reassessment exists to detect sedation before breathing slows dangerously. A due reassessment that depends on the nurse noticing a small icon on a list she may not return to for an hour is an error-prevention failure, not only an inconvenience. It also interacts with problem 2: even when the nurse remembers, splitting the sedation score and respiratory rate across two screens makes it easy to record the pain score and skip the sedation check that matters most for safety.
Recommendations and What They Would Save
First, add an active task in the nurse's task list, generated when an as-needed opioid is given and due at 30 minutes, which opens directly to the reassessment form. Second, build a single reassessment form containing pain score, sedation score with descriptors, respiratory rate, and response, filed with one click. Third, remove the duplicate free-text response field or populate it from the form. Fourth, highlight the current time column. If implemented, the reviewer's walkthrough of a mocked-up version suggests the task would fall to about 8 clicks and one screen, saving roughly 1 minute 50 seconds per reassessment, or about 15 minutes per nurse per shift, and would make the sedation check impossible to skip without choosing to.

What the NU 725 Unit 5 instructions ask for
The Unit 5 assignment asks you to conduct a usability evaluation of a clinical information system screen or task. Expect to identify the task and the typical user, choose a usability method such as heuristic evaluation or a cognitive walkthrough, and document the problems you find with severity ratings. Many versions ask you to recommend design changes and explain how they would improve safety or efficiency. Check whether your section names a heuristic set, such as Nielsen's ten or Zhang's adaptation, or lets you choose one. A task with clear safety stakes gives the review more to say. You usually do not need multiple participants for a heuristic review, but you should explain who did the evaluation and how. Screenshots are often allowed if they show no patient data.
How the NU 725 Unit 5 example is put together
The review starts by defining the task in one paragraph and the user in another, including how often that user performs it. The method section names the heuristic set and gives the severity scale before any finding, so ratings can be checked. The walkthrough is numbered step by step, which lets the grader follow exactly where problems appear. Findings are written one per problem, each tied to one heuristic and one severity level, so nothing is double counted. The clinical section explains why the highest-rated problem matters, linking the missed reassessment to the timing of opioid-induced respiratory depression. Recommendations are specific design changes, such as a single reassessment form with all four required fields, and each one states which problem it removes and how many steps it saves.
NU 725 Unit 5 rubric: what full points look like
Herzing rubrics for a usability evaluation generally give points for describing the task and user, applying a recognized method, identifying and rating problems, connecting problems to patient safety or efficiency, recommendations, and writing. Method points require a named heuristic set or technique applied consistently. The findings criterion rewards problems tied to specific heuristics with severity ratings that follow a stated scale. Safety and efficiency connections are often where top scores are separated, since full credit asks why a problem matters clinically. Recommendation points go to concrete design changes linked to each problem. The final criterion covers clear organization, numbered steps or tables where helpful, and APA 7 citations for the usability method and clinical evidence such as Nielsen's text and the opioid monitoring literature.
Common NU 725 Unit 5 mistakes, and how to avoid them
Students most often lose points in Unit 5 by describing what they dislike about a screen without tying each complaint to a heuristic. Severity ratings without a stated scale are another frequent problem. Some reviews list the same issue under several heuristics, which inflates the findings. A walkthrough that skips steps hides where the problems occur. Missing the clinical consequence is a common gap, especially for documentation tasks that seem routine. Recommendations such as make it easier are too vague; describe the change. Including screenshots with patient names is a serious error. Finally, choose a task you can describe precisely, because broad targets like the whole admission navigator produce long, shallow reviews that are hard to grade.

NU 725 Unit 5 questions, answered
Which heuristic set should the review use?
Use whichever your instructions name. Where the choice is open, the established general heuristics for interface design are widely accepted, and health specific adaptations exist for clinical systems and for safety sensitive tasks. Cite the set you adopt and apply it consistently, because findings mapped to principles from three different frameworks cannot be compared or counted.
How many participants does this need?
Often none. A heuristic review is an expert inspection rather than a study, and the reviewer walks the task while applying the principles. If your instructions do call for observing clinicians, treat that as human participant work and follow whatever approval your program and workplace require, keeping any patient information out of the record entirely.
Should I include a redesign in this piece?
Only if the instructions ask for one. Findings and a proposed interface are different deliverables, and mixing them tends to shrink the findings section into a preamble. Where a recommendation is expected, keep it proportionate: name the change each finding implies, and leave the full proposal, with its cost and its adoption problem, to a later piece.
Where can I find a free NU 725 Unit 5 sample paper?
The whole NU 725 Unit 5 pain reassessment review is posted here free of charge, including the walkthrough, findings and severity ratings. A custom usability review can be written for whichever screen or task your section assigns.
How do I rate the severity of a usability problem?
State a scale before you rate anything, for example from cosmetic to catastrophic, and define each level by its effect on the user and the patient. In this sample a missed opioid reassessment is catastrophic because it can delay detection of respiratory depression.
