Requirement Statement: One Isolation Status for Each Inpatient, Entered Once by Order and Shown Identically in the Record Header, the Patient List, the Door Sign and the Transport Request, Written So Two Builders Would Produce the Same Screen
The Problem in One Paragraph
In our 310-bed hospital, a patient's isolation status is recorded in four unconnected places: a free-text field in the record header, a checkbox on the nursing admission form, a door sign printed from a separate template and a field on the transport request that clerks fill in by hand. Last month, a patient with Clostridioides difficile infection was transported to radiology without contact precautions because these four places disagreed. This requirement replaces them with one isolation status per patient, created and ended only by order, and displayed from that single source everywhere the information is needed. The requirement is written so that two builders, working separately from this document, would produce the same result. Where a choice has been left open, the document says so.
Definitions
Isolation status. The set of transmission-based precautions currently in effect for one patient. A patient may have none, one or more than one.
Precaution types. Exactly six values, matching the hospital's infection prevention policy, which follows national isolation guidance (Siegel et al., 2007): Contact; Contact, enteric (soap and water hand hygiene required); Droplet; Airborne; Airborne and Contact; Protective environment. No other values may be entered.
Reason. The organism or condition requiring precautions, chosen from the infection prevention department's list, with an "other, specify" option limited to 60 characters.
Start and end. Date and time the precautions began and ended.
Functional Requirements
R1. Single source. Isolation status shall be created only by an order, "Isolation precautions," containing precaution type, reason and start date and time. No other screen shall allow isolation status to be entered or edited.
R2. Who may order. The order may be placed by a provider, by an infection preventionist, or by a registered nurse under the existing nurse-initiated isolation protocol. A nurse-initiated order shall require co-signature by a provider or infection preventionist within 24 hours, but shall take effect immediately.
R3. Who may end. The order may be discontinued only by a provider or infection preventionist, and discontinuation shall require selection of one of three reasons: criteria met, ordered in error, patient discharged.
R4. Header display. When one or more isolation orders are active, the record header shall display a yellow band with the text "ISOLATION:" followed by each active precaution type, separated by commas, in the order the orders were placed. When no order is active, the band shall not appear. The band shall be visible on every screen of the patient's record.
R5. Patient list. Every unit patient list shall include a column titled "Isolation" showing the same text as the header band, without the prefix, or blank if none.
R6. Door sign. On signing an isolation order, the system shall print a door sign for each precaution type to the unit's default printer, using the infection prevention department's approved sign templates. On discontinuation, the system shall print a notice to remove the sign.
R7. Transport and procedure requests. The isolation field on transport, radiology and procedural requests shall be populated automatically from the active orders and shall not be editable by the requester.
R8. Transfers. Active isolation orders shall remain in effect when a patient transfers between units and shall trigger a new door sign at the receiving unit.
R9. Legacy fields. The free-text header field and the admission form checkbox shall be removed from view. Existing data in them shall be archived and not displayed.
Acceptance Criteria
Each requirement will be accepted when a tester can demonstrate the following. A1: placing an order for Contact precautions produces the header band "ISOLATION: Contact," a list entry "Contact," a printed contact sign and a transport request showing Contact, all within one minute. A2: adding a Droplet order to the same patient changes all three displays to "Contact, Droplet." A3: a registered nurse can place but not discontinue an order. A4: discontinuing the Contact order removes it from all displays and prints a removal notice. A5: a transfer to another unit prints a door sign at the receiving unit. A6: no screen other than the order allows isolation to be entered.
Decisions Deliberately Left Open
Two design choices are not specified, and the requirement says so rather than letting builders choose silently. First, the exact shade of yellow and the font size of the header band are left to the vendor's accessibility standards, provided the band is readable by staff with common color vision deficiencies. Second, whether the patient list column appears first or elsewhere is left to each unit's list configuration. Both choices were discussed with the clinical informatics group, and neither affects safety.
Why This Level of Detail
Informatics failures often come not from missing functions but from ambiguity about what a function should do in the situations its authors did not picture. Researchers who reviewed errors related to patient care information systems described how systems can fragment information that clinicians expect to see together, creating the conditions for mistakes (Ash et al., 2004). Our four disconnected isolation fields are an example. A sociotechnical view of health information technology treats hardware and software, clinical content, the user interface, people, workflow, organizational policies and external rules as interdependent (Sittig & Singh, 2010), and the requirement touches most of them: the order is content, the band is interface, the protocol is policy and the transport request is workflow. Writing each element precisely is how the requirement keeps those dimensions aligned.
The requirement was reviewed line by line with the lead analyst before it was finalized, using a simple test: for each sentence, the analyst described what would be built. Three sentences produced two different descriptions and were rewritten. One, about transfers, originally said signs would print "on arrival," which the analyst read as the moment the transfer order was signed and I meant as the moment the patient reached the new unit. The final wording ties printing to the bed assignment event, which both of us describe the same way. That exercise, more than any template, is how a requirement earns the claim that two builders would produce the same screen.
The requirement will be kept under version control, and any change after approval will be dated and explained.

NR 541 Week 2 instructions, in plain terms
A requirement statement is this week's deliverable. Prompts usually ask you to describe a clinical need and write requirements for an information system solution, often with functional requirements, data definitions and acceptance criteria. Define every term the builder will need, including allowed values. Write each requirement as one behavior a tester could observe. Specify who may do what, what is displayed where and what happens in edge cases such as transfers. Add acceptance criteria that turn requirements into demonstrations. State any choices you have deliberately left open. Test the wording by asking a builder to describe what each sentence would produce. Cite clinical and informatics sources in APA 7.
How the NR 541 Week 2 example is put together
The statement opens with the problem in a paragraph: four unlinked isolation fields and a transport without precautions. Definitions fix the six precaution types to infection prevention policy based on national guidance. Nine functional requirements follow, each numbered, covering the order as single source, ordering and discontinuation rights, the header band, list column, door sign printing, request population, transfers and removal of old fields. Six acceptance criteria describe demonstrations. A section names two decisions left open and why. The statement closes with research on system-related errors and a sociotechnical model, and describes a review in which three ambiguous sentences were rewritten after an analyst read them differently.
Where the points sit in the NR 541 Week 2 rubric
Requirement statement rubrics typically reward a clearly described clinical need, precise and testable requirements, complete data definitions, attention to users and workflow, acceptance criteria and grounding in evidence. Higher marks go to statements in which each requirement can be tested by observing a single behavior. Defining allowed values, rather than leaving them to the builder, shows precision. Covering edge cases such as transfers and multiple precautions demonstrates thoroughness. Stating which choices are left open shows judgment rather than omission. Linking the design to a sociotechnical view of health information technology shows theoretical grounding. Clear numbering and citations support the presentation criterion. A requirement tested by a builder before submission, with rewrites recorded, is often the difference between good and excellent.
NR 541 Week 2 help from the desk
Weak requirement statements describe goals, such as improve isolation communication, rather than behaviors. Write what the system will do. Another common gap is leaving data values undefined, so each builder invents a list. Fix the values. Students also forget who is allowed to do each action. State roles. Avoid requirements that combine several behaviors in one sentence; split them so each can be tested. Do not omit edge cases, which are where systems fail. Say which design choices are open. Finally, read each sentence to a builder and ask what they would build, since ambiguity is invisible to the person who wrote it. Keep a version history so later changes can be traced to a reason.

NR 541 Week 2 questions, answered
What makes a requirement testable?
A tester who has never met you should be able to run it and get one answer. Replace judgment words with the observable thing you meant: not that the alert should fire promptly, but that the alert appears before the order can be signed. If two readers could disagree about whether the finished screen passed, the line is still a wish.
How much detail is too much?
Stop at the point where more detail starts choosing the design. Saying the nurse must see the last three readings without leaving the task is a requirement; saying they appear in a blue box on the right is a decision belonging to the builder. Over-specifying reads as competence in the classroom and closes off better solutions in the workplace.
Do I need a real system to write one?
No, and many sections hand out a short scenario for exactly that reason. Write against the generic behavior of an electronic record rather than a named product, describe screens by what they do, and the statement stays gradeable. If you do borrow from work, keep the vendor, the ward and the people out of the paper entirely.
Where can I find a free NR 541 Week 2 sample paper?
The single isolation status requirement shown above is the whole NR 541 Week 2 sample, posted in full. If you need requirements written for another clinical problem, send us the workflow and users and a testable statement can be prepared.
How detailed should an NR 541 requirement statement be?
Detailed enough that two builders would produce the same result. The sample defines allowed values, numbers each behavior, adds acceptance criteria and states which choices are deliberately left open.
