Three databases, four concept blocks and a flow from [388] records to [11] retained studies fill this NU800 Unit 3 search report, with every exclusion reasoned one by one. Searches like "nu 800 unit 3 assignment example", "nu800 unit 3 sample" and "nu800 unit 3 example" land here.
What a finished NU800 Unit 3 search strategy report looks like
Two tables and a flow diagram sit inside four pages of prose. Up front, a paragraph restates the PICOT question and marks which elements became search concepts: setting, intervention and outcome, while comparison and time are left to screening. Table one lays out four concept blocks, hospitalized adults, rapid-acting insulin, meals and timing, and hypoglycemia, with CINAHL and MEDLINE subject headings in one column and free-text synonyms beside them: inpatient*, hospitali*, prandial, mealtime, tray*, insulin aspart, insulin lispro, hypoglyc*. Table two logs each database run with its date, limits and hit count, including the abandoned first string. Limits carry a reason each: publication years [2008] onward, English, adults. The diagram carries [388] records to [270] after duplicates, [41] read in full and [11] retained, [3] of those reached through reference lists.
How a NU800 Unit 3 example is structured
The report is organized as a sequence of decisions, each carrying the reason a committee would request. Comparison stays out of the string because studies describe usual timing in too many ways to search; screening handles it. The failed string gets its own paragraph: insulin timing alone pulled the outpatient pre-bolus literature, so the revised search requires a hospital term from the setting block and adds a NOT for closed-loop and pump studies, admitting the NOT could drop an inpatient pump paper and reporting a spot check of [20] removed records that found none. Four exclusions follow, each justified. Insulin infusion protocols in intensive care follow separate algorithms. Pregnancy brings different targets. Studies testing basal dosing alone address another cause. Home and clinic studies lack a tray. Gray literature, the last paragraph notes, came from two professional guidance documents.
Concepts drawn from the question
Setting, intervention and outcome become four search blocks; comparison and time are handled at screening, with a sentence explaining the choice so the omission does not look like an oversight.
Headings and free text side by side
Subject headings differ between CINAHL and MEDLINE, so each block shows both vocabularies plus the truncated synonyms that catch authors who never used the indexed term.
The string that failed
The first run, with insulin timing and no setting term, is logged with its hit count and the reason it was abandoned, followed by the hospital block and the pump exclusion that replaced it.
Exclusions with reasons
Intensive care infusions, pregnancy, basal-only studies and home settings are each removed in a sentence saying why, which is what a committee checks when a familiar paper is missing.
From records to retained studies
A flow diagram gives bracketed counts at every stage and shows the reference-list additions separately, so the database yield is not overstated.
Where marks go in NU800 Unit 3
Reproducibility is the test most NU800 faculty apply to a Unit 3 search report: could a colleague rerun it and land near the same number? Reports naming databases without strings, dates or limits fail that test before anything else is read. Exclusions given without reasons draw comment, especially when a well-known study is absent and the report cannot say whether it was missed or removed. A NOT operator used without a spot check invites the question of what it silently discarded. Strings relying only on free text, or only on headings, suggest one vocabulary was never tried. Hiding a failed string gains nothing; showing it, as the sample does, tends to earn credit for judgment. Flow counts that do not add up are noticed quickly, and unexplained date limits prompt questions about older evidence.
Get a NU800 Unit 3 example written to your instructions
Your PICOT question, any strings already tried, failed ones included, the databases your library licenses and the Unit 3 instructions with rubric are enough to begin. A free first custom sample, returned within 24-48h, sets out concept blocks, logged strings, reasoned exclusions and a flow diagram built for that question, with brackets wherever a count must come from your own run.
NU800 Unit 3 questions, answered
Should a failed search string be reported?
Often yes, when it changed the strategy. A committee reading the final string cannot tell why it looks the way it does unless the earlier version appears. The sample logs its first run, which pulled outpatient pump studies because no setting term was attached, and shows the hospital block that fixed it. Dead ends that taught nothing can be left out.
Is it safe to use NOT in a database search?
It can be, with care, because NOT removes every record carrying the term, relevant or not. Many librarians advise against it for that reason. The sample uses it once, for closed-loop and pump studies, then checks [20] removed records by hand and reports that none were inpatient timing studies. That check is what makes the choice defensible.
Does the search need gray literature?
Many sections expect at least some, since practice guidance often sits outside journals. For inpatient glucose management, the American Diabetes Association's annual hospital care standards and a hospital medicine society implementation guide are obvious sources. The sample searches both and admits the narrowness in its limitations paragraph. Add whatever your section names; the report format stays the same.
