Standards Comparison: Keeping an HL7 Version 2 Results Feed or Moving to FHIR Queries for Reference Laboratory Results, Judged for a Practice With One Part-Time Analyst
The Decision and the Constraint
Our six-provider family practice receives results from its reference laboratory through an HL7 version 2 feed: the laboratory pushes an observation result message for each finalized test to an interface engine run by our EHR vendor, which files it in our record. After the nine-day stoppage described in an earlier assignment, the practice administrator asked whether we should move to the newer standard, FHIR, under which our EHR would query the laboratory's system for results through an application programming interface. Both the laboratory and the vendor say they support both approaches, which is exactly why a comparison is needed.
The constraint is concrete. Our informatics support is one part-time analyst, a medical assistant trained on the EHR, working about ten hours a week on system tasks. Our technology budget for the coming year has no line for new interfaces beyond what the vendor contract already includes. Any option must fit inside that.
Criteria, Stated First
Six criteria were set before either option was examined, based on what went wrong during the stoppage and on what a small practice can sustain:
1. Cost to enable and run, as quoted by the vendor and the laboratory.
2. Ongoing support burden for a part-time analyst.
3. Failure visibility: how quickly a stoppage would be noticed.
4. Field completeness: whether values, units, ranges, flags and comments arrive intact.
5. Maturity in our specific setting: whether our laboratory and our EHR version have used this approach with other small practices.
6. Direction of travel: whether the option fits where federal policy and the industry are going.
The Comparison
Table 1 applies the criteria to both options.
Table 1
Two Results Exchange Options Against Six Criteria
| Criterion | HL7 v2 results feed (current) | FHIR query to the laboratory |
|---|---|---|
| Cost | Already paid within the vendor contract | Vendor quote of $4,800 to configure plus $175 a month; laboratory quote not yet received |
| Support burden | Low day to day; certificate renewals and mapping changes handled by the vendor | Higher at first: query schedules, authentication tokens and error handling must be set up and watched |
| Failure visibility | Poor: a stopped feed is silent unless someone counts results | Better in principle: a failed query returns an error, but only if someone reads the error log |
| Field completeness | Complete in the message; our display dropped comments | Depends on the laboratory's mapping; comments may travel in a note element, or may not |
| Maturity in our setting | Used by the laboratory with most of its clients for years | The laboratory has two clients live, both hospital systems with full-time analysts |
| Direction of travel | Stable and widely used, but not the focus of new federal requirements | Aligned with the standards-based interfaces encouraged under the Cures Act rules |
Note. Cost figures are the quotes the practice received in September; the laboratory's own fee was pending.
Reading the Table
On cost and support burden, the current feed wins clearly for a practice our size. FHIR's resource-based, web-friendly design was intended to make implementation simpler than earlier HL7 standards (Bender & Sartipi, 2013), and for organizations building new applications it often is. But simplicity for a developer is not the same as simplicity for a medical assistant with ten hours a week. A query-based approach adds moving parts that someone at our practice would have to watch: when the queries run, whether authentication has expired, and what to do when a query fails.
On failure visibility, FHIR is better only in principle. A failed query does produce an error, but an error in a log that nobody reads is as silent as a stopped feed. The nine-day stoppage was a monitoring problem, and a new standard does not supply monitoring.
On field completeness, the result depends less on the standard than on mapping. Our hemolysis comment arrived intact in version 2 and was lost at display. Under FHIR, the same comment would have to be mapped into the right element by the laboratory and displayed by our EHR, and neither is guaranteed.
On maturity, the difference is decisive. Ayaz et al. (2021) reviewed 80 published articles on FHIR and identified open questions and challenges alongside its growing role. Our laboratory's FHIR experience is with two large hospital systems, and we would be its first small practice. On direction of travel, FHIR clearly has the future. The federal rules implementing the Cures Act emphasize standardized application programming interfaces (Office of the National Coordinator for Health Information Technology, 2020), and newer capabilities will come to FHIR first.
One further point applies to both options. Whatever standard carries our results, the practice will still need someone to own the route, to count what arrives and to act when the count falls. That requirement is the same under either option, so it cannot decide between them, but it has to be budgeted under both.
Verdict
Keep the HL7 version 2 results feed for the next twelve months, and add the two monitoring steps already proposed: a daily count of results against courier pickups and a vendor alert when any feed goes quiet for 24 hours. Turn on the comment indicator in the physicians' results inbox. Revisit FHIR next September, when the laboratory expects to have small-practice clients live and when our vendor contract comes up for renewal, and ask then for a fixed price that includes monitoring.
This verdict is not a judgment that the older standard is better. It is a judgment about which standard this practice can run safely with the people it has. The comparison shows that most of what went wrong this year would have gone wrong under either standard, because the missing pieces were ownership and monitoring, not format.
What Would Change the Verdict
Three developments would reverse this recommendation before next September. If the vendor offered FHIR results retrieval with its own monitoring and support included at a flat price, the support burden criterion would move in FHIR's favor. If the laboratory announced an end date for its version 2 service, direction of travel would become a deadline rather than a preference. And if the practice hired a full-time informatics nurse, the practice's capacity, which is the constraint behind every row of the table, would change. The administrator has agreed to treat any of these as a trigger for a new comparison.

Reading the NR 515 Week 5 instructions
The Week 5 assignment asks you to compare health information standards or technologies for a specific purpose. Prompts typically ask you to describe each option, set criteria, compare them and recommend one for a named organization. Name options at the level of the specification, not with vendor slogans. State your criteria before discussing either option, and include the practical ones, such as cost, support and monitoring, not only technical features. The recommendation should fit the organization's size and resources. Many sections expect a comparison table. Check the page range, whether cost figures must be sourced, and whether your recommendation needs a timeline or conditions that would change it.
Inside the NR 515 Week 5 example
The example opens with the decision and the constraint, citing the earlier stoppage as the reason the question arose. Six criteria follow, set before the options are discussed. Table 1 applies them, with quoted costs and a note on their source. The prose takes the criteria one at a time: the current feed wins on cost and burden, FHIR's advantage in failure visibility exists only if someone reads error logs, completeness depends on mapping, and maturity in this setting is decisive. A systematic review and the Cures Act rules support the policy criterion. The verdict is conditional, and a final section lists three developments that would reverse it.
NR 515 Week 5 rubric: what full points look like
Points in the standards comparison usually go to accurate description of the options, well-chosen criteria, a fair comparison and a justified recommendation. The comparison criterion rewards honest weighing, including admitting where the rejected option is stronger. Graders look for recommendations that fit the organization described, so a verdict suited to a large hospital loses points in a small-practice scenario. Sources should support claims about each standard. Tables are graded on clarity and on whether they match the prose. APA 7 format, organization and clear writing for a mixed clinical and technical audience make up the rest, and most rubrics also reward naming the conditions under which your verdict would change.
NR 515 Week 5 help from the desk
The most costly mistake is comparing two options without stating criteria first, which makes the verdict look chosen in advance. Another is choosing the newer standard because it is newer, without asking who would run it. Students also leave cost and support out entirely, though they usually decide the question for small organizations. Be precise about what each standard does; a vague claim that one is more interoperable earns little. If you use cost figures, say where they came from. Finally, make the recommendation actionable. Say what to do now, when to revisit, and what would change your mind, so a reader could act on it next quarter. A verdict with conditions attached is stronger than one presented as final.

NR 515 Week 5 questions, answered
Which two formats should the paper compare?
Whichever pair the section names, and where the choice is open, pick two that a real clinic would genuinely weigh against each other. Comparing a modern query approach with the message format a laboratory already sends produces a useful paper. Comparing two options that no single organization would ever consider together produces an exercise with no decision inside it.
How much technical detail belongs in the comparison?
Enough to show the writer knows what each format transmits and in what shape. Segment structure and resource names can be mentioned once to establish that, then the paper moves to the criteria, where the marks actually sit. A comparison that spends three pages on specification detail and one paragraph on the clinic has inverted its own weighting.
Does the recommendation have to pick one?
Yes, with conditions. Instructors mark down papers that survey both and decline to choose, because the assignment is testing judgment under constraint rather than knowledge of two specifications. The honest version picks one, names the condition that would reverse it, and states which parties would have to agree for the choice to become real.
Where can I find a free NR 515 Week 5 sample paper?
