I’m writing this blog in preparation for the European Public Health conference in Stockholm, 1-4 November 2017 (#EPHStockholm). At the conference I will be presenting the #ScotPublicHealth work on quality and impact of tweeting during 2016 (read JPH paper here; please contact me if you do not have access to the article and would like a copy). I have recorded a dry run as a “video abstract” (far from perfect, but useful preparation for the presentation itself). Full slides are available too.
The #ScotPublicHealth work emerged from the Scottish Public Health conference in Peebles, November 2015. It was clear that we should be attempting to network and share better across the Public Health community in Scotland – it was not enough to meet at an annual conference. Colleagues spread across large distances in Scotland did not have an opportunity to meet and discuss topics of mutual interest. I set out to improve connections using Twitter, but quickly learnt that colleagues wanted more advice about tweeting (see write up of #ScotPublicHealth tweet chat January 2016).
The series of blogs and webinars that we ran around #ScotPublicHealth in 2016 has been described in a series of blogs on this page; these activities were an attempt to learn more about public health topics and social media and internet technology. We looked at physical activity with Prof Chris Oliver, assets based approaches to improving health with Glasgow Centre for Population Health, health inequalities with NHS Health Scotland and Institute of Health Equity, and realistic medicine with Scotland’s Chief Medical Officer and an expert panel.
I compared tweets posted about “public health” in Scotland between September and December 2014 and compared these with tweets using the #ScotPublicHealth hashtag Autumn 2016. There was an increase in the quality of tweets as assessed by the % tweets with an image, URL and/or mention.
There was also an increase in the impact of these tweets as assessed by the % retweeted (and the number of retweets achieved). The greatest impact was seen in tweets that used more than one key component (mention of another Twitter user, image and/or URL).
It is clear from the findings that while general “public health” tweeting has improved, conference tweeting remains an area for improvement. Some people will only tweet on professional matters when prompted, for example at conferences. In my study this group of “conference tweeters” was less experienced than colleagues who had engaged in the #ScotPublicHealth work throughout 2016. Conference tweets in the #ScotPublicHealth study were less likely to include an image (which draws the eye in), a URL (which provides further information), or mention another Twitter user (which helps sharing). There was only a modest increase in quality of tweets between the 2014, 2015 and 2016 conference (⬆pictures, very small increase in use of URL though remained a small minority at 12% in 2016; no increase in mentions of other Twitter users).
The low use of URLs in conference tweets is a feature of other Public Health conferences – eg FPH conference in Telford July 2017, EPHVienna conference November 2016 and APHA conference November 2016. The under-utilisation of URLs at Public Health conferences is a missed opportunity. Microbiologist Jon Otter and colleagues have demonstrated that the URL is important in professional sharing, and this has resulted in very effective and informative tweeting at microbiology conferences (see summary in Lancet Infectious Diseases Media Watch article). If there isn’t a link to a paper, blog or video that explains the findings presented at a conference then people will be less likely to share it on social media. As scientists and clinicians we need to assess the credibility of information before we can assess whether we want to broadcast it.
The #ScotPublicHealth work led me to explore different ways of analysing social media reach and impact. The focus has shifted away from #ScotPublicHealth, which was a concentrated and concerted effort to learn about tweeting and study impact. If Twitter is about learning, networking and broadcasting then we need to look outside the boundaries of Scotland, to the rest of the UK, Europe and worldwide. There is a lot of learning available from Twitter if you know where and how to look.
Some of this more advanced analytical work has been written up on this blog, for example:
- analysing the impact of a BMJ cover article that quoted some of my social network analysis work
- quantifying the geographical reach and social media connections of child and public health advocacy work in Scotland during 2017
- assessing the impact of a jargon free blog on quality improvement against a number of measures – connections, reach, impact on individuals, reaction to the language and approach.
Other learning is captured on my Storify page. For example, a NodeXL search for “health inequalities” or tweets that mentioned both “health” and “poverty” collects together “top tweets” (by number of retweets) on the topic. Looking just at those tweets with at least 10 retweets (n=79 tweets for the period studied), 15 of the tweets (19%) were by or about Public Health in Scotland, from 9 tweeters. That is a huge impact for a country of only 5.3 million people. While this success cannot be attributed to the #ScotPublicHealth work directly, many of the Scotland-based tweeters in this list were directly involved in #ScotPublicHealth activities during 2016, and we all learnt from each other. That was the whole purpose of #ScotPublicHealth.
In another example, the RCPE symposium “Public Health in a Changing World” achieved much greater reach and spread than meetings of a similar size on other specialties in the symposium series. See the write up of the symposium and social media activities here.
Early November is Public Health conference season – in Scotland (#ScotPublicHealth; 2-3 November), Europe (#EPHStockholm; 1-4 November) and the US (#APHA2017; 4-8 November). I will be using NodeXL to extract and study the tweets emerging from these conferences, and will post Storify summaries shortly after each event using methods described in a “step by step” guide (as used for the Quality2017 referenced in the animated NodeXL map above). If you’re at any of these conferences, remember the golden rules of tweeting – include a weblink and hashtag, name drop, and add a picture (following BLONDE advice via Theresa Porrett).
