I don’t have a background in health so my exposure to
systematic reviews is limited. During my time as an information scientist I do
however have experience in using machines to find things. I did it enough times
and under enough pressure that I got pretty good at it. It is with this
background that I have found systematic reviews as a ‘thing’ of interest in my
new guise of an Academic Liaison Librarian.
Those familiar with information science or the science of
science will be familiar with a chap called Derek de Solla Price, who is
regarded as the father Scientometrics. He wrote a book in 1963 called Little Science, Big Science which I am
pretty sure anyone with an interest in Scientometrics will have cited at some
point. Within the book, Price proposed an idea called the exponential growth of
science and how every 15 years or so, all of science (measurable by scientific
papers) doubles. This sort of growth is non-linear and more like the growth
pattern of a population. The differentiating part of Price’s hypothesis is that
science or more specifically a scientific field will eventually saturate.
Visually, the exponential growth of science slows down and becomes more like a
logistic curve (see here).
People with my background will acknowledge that Price
isn’t Nostradamus and that in the 1960’s paradigms like sociological
functionalism were more au fait. The interesting thing is how 50 years later,
the common sense surrounding an idea slowly gaining momentum, becoming rapid
then finally slowing down fits when it comes to scholarly communication and
behaviour of scientists. After all, moving on to new things is a key part of
scientific progress. It’s all these thoughts that juggle around in my head when
systematic reviews come to mind.
When I add in other bits of information I have read about
and what I classify as tacit knowledge I have several thoughts about systematic
reviews I would like to share:
1. Classificatory
Language – When the words systematic
and review are put together it seems
to have taken a life of its own. A lot of papers and student dissertations have
systematic review in the title but do they all mean the same thing? Scientists
(and students they end up supervising) often produce papers that sit somewhere
between acting systematically and a full blown Cochrane Review. Perhaps a
solution in the future could be some sort of double compound noun where a word
before “systematic review” could be used to classify and differentiate.
2. Fudging
but not cheating – You know the data you want or the papers you want to use
already, you want it to look scientific and be persuasive but you do not want
to be overwhelmed. On top of all of this, you want to swat away anyone accusing
you (or your data) of bias. It is these processes and thoughts that run through
a systematic reviewer’s mind when they fudge their data/retrieval.
3. Publish
or Perish – This is where I start sympathising with scientists. They typically
have enough on their plate in a modern university, so forming a research team
or Matthew Effecting their students to co-authoring papers must be like light
at the end of the tunnel. At least they can fulfil work commitments as well as
be research active.
4. Impact
& Open Access – There are a few posts in the LSE Impact Blog that advocate
Systematic Reviews and the whole shtick of publishing shorter, better, faster
and free. Open access and PLOS One instantly come to mind, and at its core the
proliferation and emancipation of journals are a good thing. The unintended consequence
however is that at a time of ‘impact’, where scientists range from Baby Boomers
to Millennials, new scholarly norms could be forming that are incorporating
systematic reviews and massively inflating their presence.
5. No
slowing down – This ties in to the point above and the exponential growth
hypothesis. I did a search on Web of Science of papers with “systematic
review*” in the Title. From 1970 to 2014 I found just over 43,000 papers with
50% of these papers coming from the period 2012-2014. I return again to
publications like PLOS One but also the suggestion that point in time there is
no slowing down of systematic review papers. Students become scientists. Students (in Health especially) get
acquainted with systematic review papers. These students that have become
scientists have students that need to get acquainted with systematic review
papers. And on and on we go…
6. Coping
Methodology – To avoid being accused of ignorance, I will like to emphasise the
value and suitability of the systematic review for health practitioners. They make so much sense. As opposed to
quantitative methods like citation analysis, at least the papers themselves are
being read. To cope with exponential growth and modern
working practices, systematic reviews are a solution and look quite nice on any
references list. As a business librarian, I am seeing more and more of my
masters students follow the systematic review method for dissertations. Again,
this makes sense and a supervisor can help the student frame and guide them toward
a good grade with hard work. Which leads on to…
7. Habitus
– This is my final point where I am thinking about the student when they breach
through and become a scientist. Their papers are quantum’s of knowledge,
exponentially growing and redefining what is acceptable with it comes to
information retrieval and scientific method. There is good and bad of
everything and perhaps this is all a matter of discourse but I would like to
encounter more acknowledgment of the dark arts surrounding systematic reviewing
and the impact it can have on scholarly communication as a whole.
