The dissemination of written educational materials may form part of an effective approach to knowledge translation. Reference Giguère, Légaré, Grimshaw, Turcotte, Fiander and Grudniewicz1 It is therefore important to explore psychiatry trainees' use of information sources, Reference Walker-Tilley, Bainton, Fernando, Wong, Ko and Warner2 as by increasing our understanding of their reading habits, we may better target information to trainees.

Although Walker-Tilley et al state that examining the reasons why psychiatry trainees accessed information sources was beyond the scope of their study, Reference Walker-Tilley, Bainton, Fernando, Wong, Ko and Warner2 they suggest plausible reasons why advanced trainees consulted journals more frequently, and textbooks less frequently, than their more junior counterparts. In addition to the reasons the authors put forward, I would also suggest that the differing information-accessing habits of senior and junior trainees can be explained by the distinction made in the evidence-based medicine literature between ‘background’ and ‘foreground’ knowledge. Reference Straus, Glasziou, Richardson and Haynes3

‘Background’ knowledge concerns well-established facts/general knowledge. The most suitable information sources for retrieving background knowledge are textbooks or electronic ‘point of care’ resources such as UpToDate (www.uptodate.com/home), Clinical Evidence (http://clinicalevidence.bmj.com/x/index.html) or DynaMed (www.dynamed.com/home). It is primarily junior health professionals or students who require background knowledge, hence Walker-Tilley et al's finding that the junior psychiatrists made more use of textbooks than their more senior colleagues.

Senior clinicians' information needs typically relate to ‘foreground’ knowledge, which is usually needed to support a specific aspect of clinical decision-making. Textbooks are not a recommended source to answer ‘foreground’ questions because these questions require a synthesis of the latest research and there is no way to ascertain which information in textbooks is, or is not, current. Reference Straus, Glasziou, Richardson and Haynes3

It is plausible that advanced trainees are using textbooks less than more junior trainees Reference Walker-Tilley, Bainton, Fernando, Wong, Ko and Warner2 because they are posing more ‘foreground’ questions (owing to the more advanced stage of their training). It is also likely that advanced trainees are posing more of these questions because they work with greater autonomy in their clinical practice than their more junior counterparts.

I did, however, find Walker-Tilley et al's categorisation of information sources somewhat confusing. In particular, the category of ‘websites’ seems imprecise because the term websites relates to a means of accessing and storing information (i.e. the internet) as well as covering a great many types of information source. The authors report that their psychiatry trainee respondents consulted websites via search engines more frequently than textbooks and journals. This accords with previous research which has found that clinicians commonly use internet search engines to access research. Reference Hider, Griffin, Walker and Coughlan4 This finding is not, however, an end in itself because search engines signpost their users to many information sources but it is not clear which sources (or what kinds of websites) the clinicians then choose to consult. Also, while it is argued Reference Walker-Tilley, Bainton, Fernando, Wong, Ko and Warner2 that Google may be a valuable tool to physicians in clarifying diagnosis, much of the information which Google finds is unfiltered, meaning that the burden of critical appraisal falls entirely on the clinician. Reference Straus, Glasziou, Richardson and Haynes3 Likewise, Wikipedia users must counterbalance the advantage of being able to find information quickly and easily with the disadvantage of this information being of variable quality. Reference Herbert, Frings, Rehatschek, Richard and Leithner5

It would be very valuable if future research could probe in more detail which websites/online resources psychiatry trainees are accessing in their clinical practice since, as Walker-Tilley et al rightly point out, it is vital that trainees continue to possess the necessary skills to identify, access and appraise relevant information at the point of clinical need.
