Nursing care issue and documenting a CINAHL search

Two exclusions do most of the work here: not a medical issue, not a workforce issue. What is left is a nursing-sensitive outcome, and choosing badly makes the search half impossible.

01

A clinical issue evidence could change — and the exclusions

The two exclusions are the most important sentences in this brief, and they are there because they rule out where students naturally go. Not a medical issue means not a disease, a treatment or a drug — a paper on sepsis management is a medical topic wearing nursing clothes. Not a workforce issue means not staffing, ratios or call-offs, which is where the strongest opinions usually are. What remains is the category of nursing-sensitive outcomes: falls, pressure injuries, medication administration errors, catheter-associated infections, restraint use, hospital-acquired delirium. These are outcomes measurably affected by nursing care itself, which is why the assignment wants one, and choosing correctly at this step makes everything downstream easier because the literature exists and is indexed under headings you can actually find, which the search half of the assignment depends on entirely. Get this step wrong and the rest of the post has nothing to describe.

The second half asks you to explain the process you would use to search CINAHL and to include your search terms, and the words include your search terms should be taken literally — write them out. A strong answer shows structure rather than a phrase typed into a box: the concept broken into parts, controlled vocabulary alongside keywords, truncation and Boolean operators, and the limiters you would apply for publication date, peer review and population. Say what you would do when the first search returns four thousand results and when it returns three, because adjusting a search is the skill being assessed rather than running one. Framing the issue as a PICO question first is worth doing even though the brief does not demand it, since the elements of the question become the search concepts directly and it makes the whole answer look deliberate rather than improvised at the keyboard.

Likely learning objectives

Inferred from the brief — check these against your own rubric.

  • 01
    Distinguish a nursing-sensitive outcome from a medical or workforce issue.
  • 02
    Structure a database search using controlled vocabulary, Boolean logic and limiters.
  • 03
    Explain how a search is adjusted when results are too many or too few.
Assignment instructionsQuoted verbatim

Read the full question

Review every instruction before using the planning guidance that follows.

Select a challenging nursing care issue (examples include falls, medication errors, pressure ulcers, and other clinical issues that can be improved by evidence in nursing). Do not select a medical issue (disease, medical treatment). Do not select a workforce issue (staffing, call-offs, nurse to patient ratios). Explain the following for the selected clinical issue. State the issue. Explain the process you would use to search CINAHL for evidence. Include your search terms
02

Turn the brief into deliverables

  1. 01
    A clearly stated nursing care issue meeting both exclusions.
  2. 02
    A described search process for CINAHL.
  3. 03
    The actual search terms written out, as the brief requires.
  4. 04
    APA citations where a framework or guideline is referenced.
03

Stating the issue, then documenting the CINAHL search

01

Choose within the exclusions

Select a nursing-sensitive outcome and say explicitly why it is neither medical nor workforce.

02

State the issue precisely

Define the problem, the population and the setting, ideally as a PICO question.

03

Break the question into concepts

Split the issue into searchable parts and pair each with subject headings and keywords.

04

Write the search

Give the actual strings with Boolean operators, truncation and the limiters applied.

05

Refine it

Explain what you would change when results are far too many or too few.

04

Building search terms that would survive replication

Recommended databases

  • CINAHL
  • PubMed
  • Cochrane Library
  • Joanna Briggs Institute
  • Your library's CINAHL search guide

Search sequence

  1. 1.
    Use your library's CINAHL guide for the exact syntax for subject headings and truncation, which differs between databases.
  2. 2.
    Frame the issue as a PICO question before searching, since its elements become the search concepts.
  3. 3.
    Run the search before describing it so the terms you report are the ones that actually worked.
  4. 4.
    Record the result counts at each step; showing the refinement is the point of the exercise.

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.

    Hypothesis Testing, P Values, Confidence Intervals, and Significance

    StatPearls, NCBI Bookshelf · 2023

    Needed for appraising the evidence a search returns, since retrieving studies and reading them correctly are different skills.

Review before submission

Common mistakes

  • Choosing a medical or workforce topic despite the explicit exclusions.
  • Describing the search process without listing any search terms.
  • Ignoring CINAHL subject headings and searching on keywords alone.
  • Presenting a single search with no account of how it would be refined.

Submission checklist

  • Does your issue pass both exclusions?
  • Are the actual search terms written out in the post?
  • Have you used controlled vocabulary as well as keywords?
  • Have you said how you would refine a search that returns too much or too little?
