Evaluate a clinical decision support system: paper guide
An eight to ten page APA final paper evaluating a single clinical decision support system chosen from AAPHelp, MYCIN, DxPlain, ABEL, GermWatcher and ISABEL, across design, privacy and security, interoperability, internet technologies and data integrity, and closing with a written compliance policy for that system.

Which of the six systems should you choose?
Six systems are offered and they are not interchangeable, so the choice you make in the first paragraph decides how easy the next nine pages will be. MYCIN and AAPHelp are historical research systems with published descriptions of their reasoning — MYCIN's backward-chaining production rules with certainty factors, AAPHelp's Bayesian approach to acute abdominal pain — which makes the design and methods of reasoning sections straightforward and the interoperability and internet sections a stretch, because neither system was built for a networked world. ISABEL and DXplain are the opposite: living products with real integration stories and thin public detail about their internals. GermWatcher, a surveillance system for nosocomial infection, sits between the two and has the clearest data-integrity story of the six. Choose according to which sections you would rather write well, then say in your thesis why that particular system is worth evaluating at all.
Methods of reasoning is a technical term and the marker is checking whether you know it. Rule-based inference, Bayesian probability, decision-analytic modelling with utilities, pattern matching, neural or other machine-learned classification are different mechanisms, and your system uses one or two of them rather than all. Clinical intent and mechanisms of intervention are also distinct: intent is the clinical problem the system was designed to solve, while mechanism of intervention is how the advice actually reaches the clinician — an interruptive alert, a ranked differential returned on request, a report generated overnight, a suggested order set. A paper that says the system helps doctors make decisions has skipped both. Where the historical record is silent on a section, say so explicitly and reason about what the system would require today; that is a legitimate evaluation, and it reads as judgement rather than as a gap. Inventing plausible detail to fill the section is the one thing that cannot be recovered.
The last two requirements are the ones that separate a passing paper from a strong one. Ten data elements with permissible values means a real data dictionary fragment, not ten field names: patient age as an integer 0 to 120, temperature in Celsius to one decimal, specimen source constrained to a coded list, culture result constrained to positive, negative or pending. Give the element, the type, the constraint and where the value comes from, because provenance is what the data integrity section is really asking about. The compliance policy then has to be a policy — a scope, who it binds, the standards it enforces such as HL7 or ASTM messaging, UMLS-based terminology, the review cycle, and what happens when a system fails to comply. Write it as a document a reader could adopt tomorrow rather than as a paragraph of recommendations, and reaffirm the thesis in the conclusion, since the assignment asks for that explicitly.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Choose a system whose public record supports the sections the paper must contain.
- 02Distinguish clinical intent, mechanism of intervention and method of reasoning.
- 03Name a specific inference method rather than describing decision support generally.
- 04Build a data dictionary fragment with types, constraints and provenance.
- 05Write a compliance policy with scope, standards, review cycle and consequences.

Course-wide instructions that accompany this question
You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes. Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages. Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor. The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
Turn the brief into deliverables
- 01An eight to ten page APA paper on one named CDSS.
- 02The five required components, each addressed in turn.
- 03At least ten data elements with permissible values.
- 04A compliance policy for the selected system.
- 05A thesis in the introduction, reaffirmed in the conclusion, and five scholarly sources.
What do the five required components each want?
Introduction and thesis
Name the system, say why it is worth evaluating, and state the thesis the paper will defend.
Design
Clinical intent, mechanism of intervention and method of reasoning treated as three separate questions.
Privacy and security
Built-in protections, then the concerns you judge still open, with the access controls that would close them.
Interoperability
Systems it connects to, standards it uses or would need, and strategies to achieve exchange.
Internet technologies
How the system interacts with the network and which internet-based standards it incorporates.
Data integrity and the data dictionary
Data sources, then at least ten elements with type, permissible values and provenance.
Compliance policy
Scope, who is bound, the standards enforced, monitoring, review cycle and consequences of non-compliance.
Conclusion
Reaffirm the thesis against the evidence assembled.
Where are the standards and system descriptions?
Recommended databases
- NCBI Bookshelf
- HL7
- National Library of Medicine
- HealthIT.gov
Search sequence
- 1.Choose the system first, then check that its published record can support all five sections.
- 2.Search each system by its originating institution for primary descriptions of its reasoning.
- 3.Read one standards source properly so HL7, UMLS and ASTM are described rather than listed.
- 4.Draft the data dictionary before the prose, because it constrains what you can claim about data integrity.
Reference shortlist
These are authoritative starting points, not a ready-made bibliography. A qualified reviewer must confirm that each source fits the assignment and supports the claim beside which it is cited.

Review before submission
Common mistakes
- Evaluating clinical decision support in general instead of one named system.
- Confusing clinical intent with mechanism of intervention.
- Saying the system 'uses artificial intelligence' instead of naming the inference method.
- Listing field names and calling it a data dictionary.
- Writing recommendations instead of an adoptable policy.
- Inventing interoperability detail for a system that predates the standards named.
- Omitting the thesis, or failing to reaffirm it in the conclusion.
Submission checklist
- One system named in the thesis with a reason it is worth evaluating.
- Method of reasoning named specifically.
- Privacy section covering both built-in protections and residual concerns.
- Standards named individually rather than as a list of acronyms.
- Ten data elements with type, constraint and source.
- A policy with scope, binding parties, standards, review cycle and non-compliance handling.
- Eight to ten pages, five scholarly sources, APA throughout.
