PubMed’s Clinical Queries can save you time when trying to incorporate evidence based medicine or evidence based practice into the fast-paced and time sensitive clinical environment or other patient settings. Clinical Queries gives you a fast and easy way to throw in a few search terms and limit to one of five categories – Therapy, Etiology (Harm/Causation), Prognosis, Diagnosis, & Clinical Prediction Guide – and begin to see some of the best types of articles related to the category and your search terms. Clinical Queries also allows you to limit the scope of your search to Broad/Sensitive – where the search includes more citations even if they may be more peripheral or less relevant – or Narrow/Specific – where the search may miss some citations but is trying to identify the most relevant core citations. When you search Clinical Queries to find citations concerning the prevention of deep vein thrombosis (dvt) with the use of compression stockings during traveling, you’ll get results similar to this (Table results searched as of 3/25/2013).
(Harm / Causation)
|Diagnosis||Clinical Prediction Guide|
|deep vein thrombosis||12166||3333||28459||2227||26308||3268||22434||1110||9529||253|
|deep vein thrombosis AND
|deep vein thrombosis AND
compression stockings AND
You can see that as you add applicable search terms with the Boolean operator ‘AND’ you can quickly reduce the number of appropriate citations that you’ll need to wade through to find good relevant evidence to support or deny the use of compression stockings to prevent (prognosis) DVT when traveling.
If this is new to you, schedule a consultation with one of our librarians for more info about using Clinical Queries as well as other searching tips and tricks we can help you with.

At Internal Medicine Report involving a case of potential infection and heroin addiction, one of the infection vectors brought up was – did the person reuse needles? For a lot of practitioners that probably seems like a pretty obvious question but one of the Hospitalists brought up a couple of other transmission vectors for practitioners to consider when looking for potential infection sources when dealing with needle administered drug addictions. Here’s 3 things to think about when working with potential infection and a needle drug addiction:
- Does the person reuse needles?
- Does the person lick the needle before injection?
- Has the person put the needle plunger in their ear?
The hospitalist conveyed that a wide held belief among injection drug users is that licking the needle will make the tip sharper and therefore ease the insertion. You can easily see that if this is their practice, injection drug users are opening themselves up to any number of contaminates from the mouth and saliva.
Did they stick the plunger where? Apparently as needle plungers become less effective, addicts may use ear wax to create a tighter seal to prolong the use of the needle which introduces another transmission vector for infections or pathogens.
