Web 2.0 tools and medical education - more sceptical comments

Last week, @drves described me as a web2.0 skeptic. Those who know me in 'real-life' would certainly agree that I ask many questions, and may doubt received wisdom. Now it seems this facet of my personality is more apparent in the online world too!



Lemley, T., & Burnham, J. (2009). Web 2.0 tools in medical and nursing school curricula*EC Journal of the Medical Library Association : JMLA, 97 (1), 50-52 DOI: 10.3163/1536-5050.97.1.010

The above paper was published in January 2009. It has been talked about a lot on twitter today because it was mentioned in a student BMJ article, which was then picked up in a blog post by Dr Ves. The finding that '45% of medical schools use Web 2.0 tools in their curricula' is that most often cited in twitter and elsewhere. So what does this mean and how did the authors draw their conclusions?

Method
A survey was conducted using Survey Monkey. Participants were identified by emailing a link to the survey to 3 different email lists:
DR-ED (for those involved in medical education) 1383 subscribers
AACN (for those involved in nursing education) 150 subscribers
AAHSL (for academic health librarians- who were asked to forward the survey to those responsible for curricula in their institution) 146 subscribers

The questionnaire is given in an appendix.Although the title and background to the article talk about web 2.0, the first questions asks about use of the following 'web 2.o/social networking tools':
  • Blog
  • Del.icio.us or some type of social bookmarking resource
  • Flickr or some type of photo-sharing resource
  • Moodle
  • MySpace, Facebook, or some type of online community
  • Podcasts
  • Videocasts
  • Wiki
  • YouTube or some type of video-sharing resource

I don't know why Moodle, which is an open-source,and flexible learning management system (LMS) or virtual learning environment (VLE) is included as a web 2.0 or social networking tool. Moodle does support the use of web 2.0 tools, but so can other VLEs, so it is unclear why it is listed here.

Results

There was no way of tracking how those who responded to the survey found it, ie did they find it on a list themselves, or was it passed to them by a librarian? In any case there were responses from 36 individuals involved in medical school education, and 19 individuals involved in nursing school education.

The response rate from the medical school list is no higher than 36/1383 or 2.6%, amd possibly lower if some of the responses came via the librarians' list.

Several responses may have came from individuals in the same medical or nursing school as responses were anonymous.

Despite this the authors go on to report results as the percentage of medical schools which are engaging in the use of web 2.0 tools, rather than the percentage of medical educator respondents. The individuals who responded that they did not use these tools may work in institutions where many others do, and the individuals who responded positively may be the sole educators in the institution to use the tools out of several hundred or more.

The questionnaire did contain a question ("Please briefly describe how these tools are incorporated into your instruction.") which allowed free-text response and could have provided some information for a qualitative data analysis, but no results are given.

My conclusion

Does this paper tell us anything about the use of web 2.0 tools in medical and nursing schools in the US? No.


Is the author's justification of validity despite low response rate, because the study is "to gain insight into an issue", appropriate? No, because exclusively quantitative results are published.

This paper is short. It is open-access. I think that with a cursory look, most people would have reached similar conclusions to me. So why were so many people referring to this paper today without any criticism of the severe weaknesses in methodology?

Thanks to @drcolinmitchell for drawing my attention to this research.
He has also published a great post about this paper.

Where do junior doctors look things up?

A short time after my post on where medical students look things up, @drcolinmitchell tweeted about a paper on where junior doctors look things up.
Hughes, B., Joshi, I., Lemonde, H., & Wareham, J. (2009). Junior physician’s use of Web 2.0 for information seeking and medical education: A qualitative study International Journal of Medical Informatics DOI: 10.1016/j.ijmedinf.2009.04.008
I have to admit that when I first glanced at this paper I thought the methodology was good. There is talk of triangulation and inter-coder reliability etc. But when it is read more deeply much of it simply does not make sense because key concepts are so loosely defined. In the past few days I have seen this paper mentioned several times on twitter and in blogs, but there has been little or no mention of the poor quality of this study. Therefore I thought I should add my thoughts to the debate.

Method

The study took place in the NHS in England. The subjects were junior doctors. 55 were identified through a stratified sample (of 10 different specialties) from 300 graduating from a London medical school. 50 of these agreed to participate but only 35 completed all three stages. More demographic data on the participants would have been useful.

Next, they were given a questionnaire, used in previous research on this topic, and asked to keep a diary over at least 5 days of every website they accessed for work. Finally each participant was interviewed although themes were saturated after 20 interviews.

Results

From the survey data, 32 of 35 said they used web2.0 sites and of these 28 used wikis (read the content, only one doctor contributed to wikis). Next, looking at the diary data, confusingly, google.com is now referred to as web2.0 content, whilst in the survey it was not. 80% (28/35) of physicians used google during the five days. 25/35 reported using wikipedia. Smaller percentages used yahoo.com, doctors.net.uk and Facebook. This data is presented in chart form with percentages of physicians accessing each site (eg google, wikipedia, NICE). Presentation in tabular form with absolute numbers of accesses would have given more information.

The participants were asked to state for each of the 444 events where they accessed information online whether this was on a wed2.0 or user-generated content site, or hybrid, or traditional content site. The doctors said that on 235 occasions they were accessing web 2.0 content. However, the authors have classed the 142 uses of google and 115 uses of wikipedia (total 257) as web 2.0 content. No absolute numbers for the access of yahoo, facebook and doctors.net are given so the agreement between the authors and participants over what constitutes web 2.0 is not clear.

The authors then present themes from the interview data. Here "using the internet" is confusingly equated with web2.0 content. There is mention that doctors look things up online because it is easily accessible, and up to date, but at times they are uncertain about the quality or usefulness of the information found. The authors introduce a taxonomy of information needs from the interviews which they then use to analyse the information needs addressed inthe diaries, categorising 237 out of 444 internet accesses/information needs:
  1. "to solve an immediate defined problem" "to advance an immediate task in the clinical context and forms a closed question with a specific answer" "closed questions" 107 of total information needs, of which 90 addressed through use of "hybrid or best evidence tools" (these tools are not specified)
  2. "background reading on a subject" 130 information needs, of which 107 addressed through the use of "web 2.0"
It is not clear why 207 web accesses were not classified, or which sites were accessed in those diary entries.

Futher information is given on the way that doctors used google. 21 out of 35 mentioned using google as a way of navigating between trusted sites. It is not stated if these trusted sites were named in the diary.

There is then some discussion of how these (web 2.0) sites could be better used in clinical contexts. Doctors mentioned :
  • patient education- comment is made of patient use of wikipedia and need to educate patients on different sites
  • physician education- awareness of "web2.0 sites" as difficulty is in finding out about sites(wikipedia and google? or were they referring to some other web 2.0 sites? or to trusted web 1.0 sites?) , not much training necessary as sites so easy to use.
  • remove blocks to web2.0 sites - it is reported that google is blocked in

I am not commenting on the discussion of the paper because I found the method and results section quite perplexing. No clear definition of web 2.0 content is given. It is not clear why the use of google is considered use of web 2.0. As Mark Hawker has pointed out google is a web 1.0 application. (Data is indexed by computers and pulled by humans. The content is not in any way user-generated or social. ) Previous researchers such as Sandars and Schroter, who this paper cite, did not consider google to be a web 2.0 application.

Because the authors did not use a clear definition of web 2.0 content this work can tell us very little about doctors use of web 2.0 content. It is possible that most doctors are using the same trusted websites that they have always uesd. They use wikipedia because it is easily accessible (free and no passwords needed) and is equivalent to an online textbook. The user-generated content of Wikipedia is not a factor for most doctors. Credibility of user-generated content for physicians did not emerge as a theme in the qualitative work. Instead they were concerned about how patients might use the same websites that they use.

Overall, I found the study very disappointing. We need debate and discussion on how best to address the informational needs of clinical staff. To me, the best description of these needs still seems to be Richard Smith's BMJ review in 1996. Now we should be asking, have the information needs of doctors changed in the last 13 years? How are these needs best addressed by current technologies and what tools should we be trying to develop.

What do you think? Am I being too harsh? Why did you like this paper?

Metaphors of Medicine... and implications for medical education

Just a short post. Last week I saw Annemarie Mol speak at COMET09 about the 'messiness' of clinical practice. Today I received an email from a colleague where we were discussiing the fact that many aspects of medicine do not "offer a script". And then through Rakesh Biswas I came across this blog of Shashikiran Umakanth, a physician and associate professor in India. His former student comments that "no patient comes in a neatly packed diagnostic disease".

So these metaphors of medicine are about its complexity and unpredictability. But do we acknowlege this in our medical courses?

What are your metaphors for medicine and how do they inform the way we prepare students to become doctors?

Tweeting from a conference.

If you are following me on twitter you will have noticed many #comet09 tweets in the last two days. There will be more tomorrow as the conference finishes in the afternoon. So what was it about? COMET is an interdisciplinary conference in communication, medicine and ethics. It moves around the world and this year was on my doorstep in Cardiff so too good an opportunity to miss.

I decided to tweet because I thought the content would be interesting to quite a few of the people I know on Twitter. And it was. Some of the things that happened:
And after seeing a presentation about using multiple modalities in drug patient information leaflets I remembered that I had seen a lightning talk about this last week at Health Camp but couldn't remember who. I tweeted and had the answer before the speaker had finished her presentation.

I do seem to have been the only person tweeting from COMET 09, but I predict that come COMET 10 in Boston there will be a few more. This was not about providing a backchannel to the conference, but simply about bringing the contents of interesting dialogues to a wider audience. So if you are listening to someone stimulating, think about tweeting. The chances are that someone you know will be glad that you have made the effort to share.

Where do first year medical students look things up?

In the last two days I have spoken to 31 first year medical students about their early clinical attachments in primary and seconday care. I asked them where they looked up unfamiliar clinical topics. These are some of the responses:
  • Wikipedia
  • Google
  • Kumar and Clark
  • Medical dictionary
  • YouTube (especially to find out more about operations)
  • NHS Direct/Choices
  • Oxford Handbook of Clinical Medicine
  • I didn't look anything up.
Wikipedia was definitely the most common choice. Many students said 'I know I shouldn't but....' and then qualified that they used Wikipedia first because it was easy to understand, they felt it was reasonably reliable, and accessible. One student used it to search directly from her phone when on placement.

I was intrigued by one student who was very keen to distinguish 'learning' which was what he did for exams... spotting questions on past papers and reviewing lecture notes... from 'experience', when he would access YouTube or Wikipedia to find out more about something that really interested him. His reluctance to call this learning reminded me of a third year student I spoke to earlier in the year. We were talking about how she would continue learning for the rest of her life. "That's so depressing", she said. In her mind learning was bound up with exams and assessment.

Should we worry about students turning to Wikipedia so often? Which other resources are just as user-friendly and comprehensive?

I think that NHS Choices is a good place to start.

EDIT: Just to make clear, the first year students I am referring to here are in an undergraduate 5 year course. The first few years of the course are pre-clinical but these early clinical attachements are to give them some initial insights into the world of clinical medicine. Some medical schools in the UK have no distinction between the pre-clinical and clinical parts of the course.

Facilitating a network

I am hoping to establish a network between those leading programmes in which medical students have the opportunity for contact early in the course with patients in their own homes or in the community. I think we will benefit from sharing motivations, materials and ideas on assessment. So I am wondering how I could support this. We could simply have an email list. Or a google group. Or a NING.

What would you use?

EDIT: This is to be a network with my peers- fellow medical educators- not with students.
