The Research Question

Clear and focused


Clear and focused research questionHow can gist knowledge of patients be measured

Is scopic stabilisation better than Bristow Latarjet for treating an Anterior glenohumeral luxation with labrum injury (no ossale disorder) in a 20 YO rugby player for recurrent luxation or other Patient Related Outcome Measures

Dietary intake and cardiovascular disease

TOO VAGUE

TOO SPECIFIC

TOO BROAD



Clear and focused

Which articles can answer the question?



Facilitators and barriers in preconception care

Predictive factors for oronasal fistulas in children treated for clef lip

Which risk factors for later maternal and neonatal outcomes can be detected by postnatal caregivers?



Clear and focused


Elements (Key Concepts):

- Watch our for Bias and Duplicates

- Which elements to use in search?


Elements : Bias

Very specific characteristicsDuration of breastfeeding and intelligence

JudgementsPoor family functioning, harsh parenting and bullying behavior


Elements : Duplicates

Considerations

Explode a broad term or not?

Start exploded, be more specific if many irrelevant results appear

Truncate a term or not?

Truncate as much as possible, hardly noise (though not too short)

Phrases or proximity?

When available, use proximity, easier and more sensitive

How broad should proximity be?

Start with 3, increase in steps of 3 and evaluate new articles


Creating a basic search strategy (summary)

Type code in Word Open an element with () For emtree terms type ''/exp and paste term After pasting all emtree terms, type OR ():ab,ti within that element once

for free text words Type single word synonyms first Type (() NEAR/3 ()) somewhere in the document to reuse Copy (() NEAR/3 ()) into the ():ab,ti part search for phrase variants, and

add the words


Optimizing your strategy

Temporarily change the syntax and check words:

Per element, keeping the rest unchanged (emtree) NOT (free text) (free text) NOT (emtree)
