Workplace Health and the Cauldron of Evidence

Scott Lloyd and Sarah Slater, Advanced Public Health Practitioners, Public Health South Tees 

Systematic reviews are brilliant. They take all the available evidence for a particular topic, do something special (stick the results into a big cauldron) and churn out a finding that informs us mere mortals in policy and practice where we should and shouldn’t be investing our money and capacity.

Double, double toil and trouble...

In these austere times, such evidence about what works and what doesn’t is so important – especially when combined with the how and why. This recent review by Jenna Panter and colleagues is an excellent example of what works and how.

However, there is one sphere of public health where we feel that systematic reviews may not paint a full and fair picture.

Let us explain.

Workplace Health

Most public health colleagues have a speciality or five. This might be a topic (e.g. nutrition or addiction) or part of the life-course (e.g. children and young people or older adults).

We are Workplace Health Specialists with 28 years of combined experience. We’ve supported employers of all descriptions, including businesses of different sizes and in different sectors. We’ve worked on national workplace health programmes, such as the Well@Work programme led by the British Heart Foundation between 2005 and 2007, and have been involved in the North East Better Health at Work Award since its launch in 2009 (arguably the biggest and most successful workplace health programme in England). We’ve a lot of experience of supporting NHS organisations who are trying to improve the health of staff – sometimes successfully, sometimes less so.

Working with such a variety of employers to improve staff health is a challenge of both knowledge and skill because they are looking to you, as the expert, to come up with evidence-based suggestions. Consider how you might support the below employers (real examples for us) to encourage physical activity in their workforce:

• A tea factory which operates 24 hours a day with mixed shifts and a predominantly female, part-time workforce
• A call centre for a bank employing 1,200 mostly young staff, in a mainly sedentary occupation
• A call centre for a public sector organisation employing workers typically aged 40 plus, in a mainly sedentary occupation
• A mining company at which the majority of the workforce arrive, take a lift down a shaft for 20 minutes, work a shift underground in 40 degree heat, resurface in the lift and get straight in the car to head home
• A category B prison. 

How would you support an employer to encourage physical activity in a call centre?

What you might suggest to each of the above five employers (and what might work) could be completely different (and probably would be). At least in each of those scenarios, the workforce is likely to be pretty homogenous. Consider working with a huge employer such as a Local Authority or NHS Trust which arguably have massive internal differences in staffing groups in terms of age, gender, hours, and roles (e.g. office staff vs refuse collectors).

We believe that these differences make workplace health a different kettle of fish compared to other settings, such as schools, colleges, universities, and prisons, which could be comparatively homogeneous. They aren’t of course – there are massive differences between schools for example, but our suggestion is that they have the potential to be very similar if all variable things (e.g. culture, policies etc.) were the same. 

What’s our point?

Firstly, that lumping trials of workplace health interventions and programmes into a systematic review masks these potentially huge differences. We’re not sure how we get around this issue but we are raising it as an issue.

Secondly, to suggest that there is a lot more research to be done. There are some workplaces that should be considered a priority. For example, the majority of the working population in the private sector (60%) are employed by small-to-medium sized enterprises (less than 250 employees) and this is an area that no-one has cracked in terms of health and wellbeing via the workplace. Another example is call centres: given the sedentary, pressured nature of the work. One feasibility trial has recently been completed (Morris et al. 2019)[1] and another is underway (involving Scott). We can’t do individual studies for every type of workplace but some should be considered a priority.

Thirdly, to highlight the skills possessed by our peers who lead on workplace health. Employers and employees can throw all sorts of issues at you from bread and [low fat] butter stuff like physical activity and mental wellbeing to stuff like menopause awareness and sleep. Not only does a workplace health specialist need to maintain a base knowledge of all these topics, but they also need to understand how it might be tackled in the various types of workplace highlighted above.

It would be remiss of us not to plug the North East Better Health at Work Award. It needs a stronger evaluation building on previous work (Braun et al. 2014)[2], but we’re talking about a programme that was launched in 2009 and has actively engaged hundreds of employers every single year since (456 currently engaged at January 2020), supporting them to promote the health and wellbeing of their staff (potential combined reach of 202,962 working adults as of January 2020) and the wider community. We’re always recruiting more businesses so if you would like to know more visit www.betterhealthatworkne.org.

Take it away: a masterclass in healthy takeaways

Post by Scott Lloyd, Advanced Public Health Practitioner at Public Health South Tees and Karen Pearson, Catering Monitoring & Advisory Officer at Redcar & Cleveland Council

Whether it is the Golden Cod or the Taste of India, independent hot food takeaways get a bad rap in Public Health circles. They serve food and drink that is predominantly higher in fat, salt and sugar and may contribute to noise pollution and other environmental ills. Furthermore, they may not be the best option for our beleaguered high streets as they tend to be shuttered up during the daytime.

Up to March 2018, for a variety of reasons (including health), 164 out of 325 Local Authorities (50.5%) have introduced powers through Local Plans or Supplementary Planning Documents (SPD) that aim to restrict the proliferation of hot food takeaways (Keeble et al. 2019)[1].

Watch this video to find out more about how we worked with takeaway owners
(click here if the video doesn't appear above)

But let’s be honest – that horse has already bolted. Analysis by Public Health England has shown that there is an average of 96.1 hot food takeaways per 100,000 population in England (Public Health England, 2018)[2].

Where we work in Redcar and Cleveland, the Local Authority introduced a SPD in 2008 that restricted the percentage of hot food takeaways (A5 class use in planning terminology) in any commercial centre to no more than 5% - but even then, each commercial centre already had more than 5% hot food takeaways.

So we have to accept that hot food takeaways are here to stay – at least for the foreseeable future. Many Local Authorities have implemented interventions such as award schemes that engage these businesses to support them to improve the healthiness of their food offerings, but with limited evaluation (Hillier-Brown et al. 2017)[3]. Indeed, we have a Food4Health award in Redcar and Cleveland, which is open to all out-of-home caterers. We were doing OK in engaging hot food takeaways but we wanted to try something different.

In 2015, the Foodscape team organised a Fuse Quarterly Research Meeting on developing interventions with out-of-home caterers. One of the presentations was by Louise Muhammad from Kirklees Council on the healthy takeaway masterclass that they had developed and delivered to over 20% of the eligible businesses on their patch. The masterclass was described as a three-hour session in which hot food takeaway owners and managers learn about the small, sustainable changes they can make so their food is a little healthier without costing a huge amount or that will actually save them money/generate new custom.

A few months later, we travelled down to Huddersfield to watch a masterclass being delivered. It was clear from the start that this was something that engaged businesses and had potential. The decision to repeat it in Redcar and Cleveland was easy.

Takeaway owners and managers learning about small changes to make their food healthier

We worked with the teams from Kirklees and Foodscape to deliver our first masterclass in May 2016. In line with what Kirklees do, we invited hot food takeaways with a food hygiene rating of three or above – the feeling was that any outlets with less than this really needed to concentrate on food hygiene first. In total, 181 invitations were sent out and 18 attended, representing 10% of those eligible – a figure that we practitioners were happy with (if not all the academics!).

The Foodscape team conducted a mixed methods evaluation to explore the acceptability and feasibility of the masterclass intervention (Hillier-Brown et al. 2019)[4]. The takeaways businesses that attended made a variety of pledges – the ones that required less effort and cost (e.g. reducing salt and sugar in pizza dough) were implemented more so than other more potentially costly or difficult changes (e.g. stocking reduced sugar tomato ketchup).

Pledging to use healthier alternatives

Has this work made the hot food takeaways in Redcar and Cleveland healthy? No it hasn’t. Like the rest of us, businesses owners have a living to make and will cater to what their customers want. But as an example, Carol - the owner of a sandwich shop in Guisborough who stars in the film above - pledged to take 10% of the sugar out of her baking. Did her customers notice? No. Did, this make her flapjacks ‘healthy’? Of course not but they are now a little healthier. Hence, has the masterclass via all the pledges made their food offerings a little healthier? Probably.

We have since delivered a further six masterclasses, with the offer extended to other out-of-home caterers such as restaurants. About 30% of all eligible takeaways in Redcar and Cleveland have now attended a masterclass, with follow up support provided by the Food4Health award.

Engaging with hot food takeaways can be difficult. We are now struggling to attract new businesses onto the masterclass and may hit a saturation point at 35% or 40% of those who are eligible. Some owners have other priorities and some may not accept the healthy eating messages. Also, some hot food takeaway owners are not even resident to the UK so engaging them is nigh on impossible. But we have to continue to try.

Another key learning point is that we need to work more closely with suppliers. The majority of masterclass attendees pledged to start using healthier alternatives, such as reduced sugar tomato ketchup or reduced salt soy sauce but they were unable to source these items from suppliers at a reasonable cost or not at all. Hence, wider work is needed with suppliers which, as one of the other Foodscape projects showed, is possible (Goffe et al. 2019)[5].

But the masterclass is an acceptable and feasible intervention to engage a good proportion of hot food takeaways. We will continue to deliver it once or twice a year as long as there is sufficient demand. We’re hoping to run the next class in September, so lookout for that.

What the masterclass doesn’t do is engage the big operators such as McDonald’s and Just Eat, accepting that the latter works mainly through local independent takeaways (but what requirements can the national corporation specify on their local deliverers?). It’s likely that national work is needed with those corporations, continuing the good work of Public Health England and others.

We also need to be mindful of the potential impact of “dark kitchens” – potentially the “satanic mills of our era”. But I’ll save that for another time…

52 weeks in public health research, part 49

Posted by Catt Turney Amelia Lake and Mark Welford

 

 Posted by Catt Turney: One of the photos taken by my colleague Britt Hallingberg at the DECIPHer symposium, where staff and students from the three partner universities (Cardiff, Bristol and Swansea) get together to discuss how our research is going and celebrate key achievements. As there are so many of us now we're only able to sympose once a year, and organising an ice-breaker at the beginning of the day is no mean feat. Luckily we had Dr. Jeremy Segrott (on the left, waving his arms in the air) on hand to conduct the task with aplomb. The ice-breaker involved a highly sophisticated and technically advanced approach to finding out our views on various subjects, by situating ourselves appropriately along a piece of string. This particular photo illustrates our views on mornings, about which we appear to have mixed feelings.

Mosaic is one of a number of commercially available geodemographic segmentation systems, applying the principles of geodemography to consumer household and individual data collated from a number of governmental and commercial sources. It's a bit scary how much it can churn out about you, your neighbours and where you live by simply entering a postcode!

The meeting was jointly hosted by the Fuse Communications Group and Knowledge Exchange Group and was centred around a blog post written by Scott Lloyd, Health Improvement Commissioning Lead, Redcar & Cleveland Borough Council.  He and his colleagues kindly agreed to give up there time to talk to us about improving partnerships, research and health.

A reminder from the Fuse blog group:

Each Thursday of 2014 we’ll try and post around four pictures on the Fuse blog that capture our weeks in public health research, from the awe-inspiring to the everyday and mundane. Given that more of the latter than the former exists in most of our lives, we foresee problems compiling 208 images worth posting on our own. So this is going to have to be a group project. Send an image (or images) with a sentence or two describing what aspect of your week in public health research they sum up and we’ll post them as soon as we can. You don’t have to send four together – we can mix and match images from different people in the same week.

Normal rules apply: images you made yourself are best; if you use someone else’s image please check you’re allowed to first; if anyone’s identifiable in an image, make sure they’re happy for it to be posted; nothing rude; nothing that breaks research confidentiality etc.

Email your posts to m.welford@tees.ac.uk or contact any member of the Fuse blog group.

Working across boundaries

**********************************

Dear Academic, 

For the past nearly three years, we’ve been running this wonderful public health intervention in our area. It’s seen 50,000 people and everyone says how great it is. We’d now like you to come in and evaluate it. Oh by the way, there’s only two months of the project left and they’ve only got a few measures collected from past service users. 

Kind Regards,

Public Health Officer.

**********************************

Sound familiar? These instances have happened in the past and are unfortunate and I can’t promise that they won’t happen in the future. However, the frustrations occur both ways. Let me explain.

Research trials – especially large randomised controlled trials – cost a lot of money. They are designed based on the latest research to provide a degree of confidence that the outcome will add to the evidence base of what works. Even if they don’t work, it is still so very, very important that the findings are published and shared (Prof Richard Parish once suggested in a meeting that there should be a Journal of Public Health Interventions that don’t work).


Open door policy (and practice)

My frustration is when I hear about trials that have taken place and have failed to recruit participants in a timely manner or at all – this is one area where us mere commissioners and practitioners can help, especially now that many of us are working in Local Authorities with an even wider reach via colleagues in other departments. We can open doors that may be closed to you.

A few examples:

• Are you conducting a trial with adults? Would you like easier access to potentially over 130,000 people in North East England? Through the medium of the North East Better Health at Work award, in 2014 colleagues worked with employers who combined to employ this many people. These colleagues and the Workplace Health Advocates that they work with could have been helping you.
• Want to work with schools? Many of our colleagues – such as Healthy Schools (in some areas), School Sport Partnerships, Active Travel Projects and Local Authority education colleagues – already have contacts. Your information coming from them direct to their contacts will always be better than you contacting schools cold.
• Communications teams in Public Health England, Local Authority, Clinical Commissioning Groups, NHS Foundation Trusts and elsewhere have a role too. They know the local media. They know our local populations. They have social media accounts with 1,000s or more of “likes” or “followers”.

There are examples where partnerships have worked really, really well. Look at “New Life, New You” in Middlesbrough. Also LiveWell; a number of colleagues have been involved in this during the development and implementation stages and the intervention team are close to recruiting the required number of participants.

 

My point is – get in touch early as I’d like to think that we can help. Senior researchers please advise your PhD students of these opportunities, especially those new to the North East. Fuse – especially AskFuse and the Knowledge Exchange theme – is breaking down barriers.

 

Even if we can’t help, it’s always good to know what is going on in our local areas (it can be embarrassing when we get asked about something that we know nothing about).

 

I can’t promise to change the world and that a joint approach will always work; but basically, as long as your intention is to improve health – I’m interested.
