DIY SOS by Hayley Lancefield

I was lucky enough to be given the opportunity to go to a DIY SOS site with one of our occupational health technicians last month, to provide mini health check to everyone who was volunteering.

I didn’t know what to expect and I wasn’t too sure if anyone would like to know their blood pressure reading, or what their glucose or cholesterol levels were. However as soon as we got to the site and started to set up, there was instant interest from the people volunteering and especially from one of the presenters, Julian Perryman. Julian came up to me and said: “It’s good that you have come onsite today as someone felt faint yesterday”.

He then waited for us to finish setting up and was the first to get a mini health check. People started lining up, and before we knew it there was always more than five people waiting in line which I was surprised to see. There were people of all ages and one of the main reasons that they wanted a mini health check was because they had never had their blood pressure reading, glucose and cholesterol levels taken before. There were a few people who were on blood pressure tablets, and said they wanted to check if they were working, as they had to wait more than three weeks to get a GP appointment.

Many of those who had a mini health check asked the occupational health technician questions about their results and how they could get better readings. There was a funny moment when another presenter, Nick Knowles, came in and said: “I know you’re all getting your checks done, however someone has just dropped off more doughnuts and cakes. Maybe have one after your check!”.

We saw about 50 people in total and Nick came for a health check towards the end. He spent some time with us to discuss how important it is for people to not just “know their numbers” but understand them too.

There was a great community atmosphere and it was good to see everyone coming together for a great cause. It seemed like everyone in the area just wanted to get involved.

The Life of a New Account Manager at Express Medicals by Joe Richardson


Although I thoroughly enjoyed the interview process I was still a little apprehensive to start my new role as an account manager with Express Medicals. As naturally, the human mind is always a little cautious to the ‘unknown’.

However, my apprehension was soon swept aside when our Commercial Manager Rory Evans welcomed me into the business. We sat and had a coffee had a general chit-chat and he explained that there was no pressure and that I should feel comfortable to develop at my own pace and enjoy the learning process, which immediately made me feel at ease.

Rory then took me around the business and introduced me to all the different departments. After meeting everyone I certainly got the feeling that this is very much a peoples company, where everyone is genuine and gets on well as a team.

During my first month here I’ve worked closely with the senior account managers Harvey and Hayley who have been extremely helpful and I’ve learned a lot from them in such a short space of time. I have felt comfortable asking them any questions however silly they might be and they have always gone out of their way to help.

I’ve been given responsibility from the outset taking over a number of accounts, also within my first month I have recently set up and attended my first client meeting. It was a great experience to be involved in a client meeting to gain insight into what kind of questions clients may have before signing a contract with us. Rory assisted me with the client’s questions and together we successfully won some new business- which was a great feeling.

There are little quirks at this workplace that make it very special.

For example, our CEO Dan Hegarty makes it his business to walk around to all the departments and check up to see how all members of staff are doing. From previous experience it is usually the staff chasing the manager or CEO around the building to get a minute of their time, but not here, this gives everyone a real sense of value and transparency throughout the business. We also have fruit and snacks week giving us the opportunity to order our favourite fruit and snacks. In the sales and marketing department we enjoy ‘foursies’ where at four o’clock when we need that energy to make it through the end of the day, we can indulge in healthy snacks.

My previous role was as a sales consultant and coming from a fast-paced, competitive sales environment it has been extremely refreshing coming into a relaxed but yet professional atmosphere where all departments work together to ensure the best results. In addition, it is clear to see the management have complete faith and trust in the staff here to get their individual jobs done as staffs are given the flexibility to manage their own time.

Everyone has made me feel very welcome and I look forward to growing with the business!

The Construction Toolkit That Could Save A Life

Health and well-being is a topical subject and current in the construction industry. My aim is to explain how National Grid tackled the issue of stress with its staff using a process I helped design.


Business and construction need to avoid assuming men know what to do about stress. They also risk assuming men don’t want help. This starts with talking about it. We don’t have to have all the answers but let’s begin and learn from it. If we don’t know what Construction workers want, let’s ask them and listen to what they say. It’s likely it won’t be much different to what the rest of us want or need. But if we ask them, they’ll know we care and that’s what matters.


Construction workers within National Grid learnt about site safety by Health & Safety Reps. The Reps had never received training in stress and mental health. So, National Grid felt the subject of stress wasn’t discussed. Managers also struggled to support staff if they took time off for stress. The subject felt like the ‘elephant in the room’ and they began a campaign to correct this. I helped design a toolkit that recognised stress early. It equipped managers with tools to make an approach to a vulnerable employee. It also covered how to support them. The benefit of this was greater confidence when discussing the subject. It improved how easy it felt to talk about personal issues. It also increased their understanding about what people needed and helped.


Some of us are lucky enough to learn the tools we need to help us cope well in life. Loneliness when working away from home or balancing work with home life can be tough. So too can handling marital breakdown or losing someone we love. If we haven’t managed to learn these or have them taught to us by parents, then we can feel ill-equipped. Communication can also be important and talking about our emotions helpful. Not talking can have significant effect on our health. Some of the time we ‘learn’ what is acceptable, or unacceptable in our behaviour from the habits we see around us. If it is ‘negative’ to express our emotions, then we will learn not to do this. Another issue is that men often find it more difficult to talk about emotion than women. There is a good reason for this.


Women experience emotions on both sides of their brains. They have many connections within the brain to the part of it responsible for language. It is much easier for women to express what they are feeling. Men still experience emotions but find it tougher to explain. For men, it can be much harder to find the right words. So, some men may choose not to speak about things, and for some it may feel more as if they can’t. Others may use different coping mechanisms such as withdrawing or avoiding things. Some may channel their distress by taking exercise or team sports and seem to avoid talking. Because men do this it doesn’t mean they want to, and it doesn’t mean someone may not be able to help. They may be well received were they to offer. The key to helping men is to offer help but in a way that appeals to them. To do that well keep the process simple.


This is much easier to do when you know someone well such as a good friend. The question ‘how are you?’ isn’t coming from management and doesn’t feel threatening. It’s also easier to ask for help from a friend rather than a professional. So, National Grid implemented a toolkit. Reps knew to look out for someone they knew well who may be struggling with stress. They didn’t try to fix the problem themselves. They acted as a friend would. The 4 symbols that represented what this toolkit looked like are below:

I developed better expertise with this process over time and revised it. I called it a Buddy toolkit or ‘looking out for your mates’. I extended it beyond Health and Safety Reps to the workers whenever I introduced this. It was important workers didn’t have to look out for everyone they knew but watched out for their best mate. It was also important not to feel they had to fix how someone was feeling or make them feel better. All you do is watch out for your mate and check in with them. When you’ve asked how they are, if they are unhappy and you think you can help offer your own thoughts. Talk about when you’ve experienced something similar. If you don’t think you can help, direct them towards someone you know who can. On site, within the business, or outside of it. Make it your business to know what services are available then you’ll know you tried and they’ll feel they matter. Keep in touch and check in again a few days later. No pressure, but you know you are there.


With the Buddy toolkit you also pair people up within your project team. If someone is new to the team, a more experienced site worker would be better paired with them for a few weeks. This is so they can show the new person the ropes but also look out for them. Often, we are at our most isolated when lonely and we don’t know anyone. This is a risk for mental health. Yet it’s also the time when men are most likely to find out what is and isn’t ok in that culture. If they are new in, need help but don’t ask, the buddy system gives them someone they can go to.


We all need people in life and this toolkit helps. What this achieves is simple; you show you care and they feel that. If they are going to reach out, then they’ll come to you. So, look, watch and ask how they are especially if you see they aren’t themselves at any time.

Health surveillance and hazard control in the workplace

Health surveillance and hazard control in the workplace

Health surveillance is a process of continuous monitoring of employees when they’re working in situations that could be harmful to health.

Companies need to conduct health surveillance is when hazards such as noise, manual handling, biological agents or other factors are present in the workplace and have known ill-health outcomes. Employers sometimes mistakenly consider surveillance as a method of ensuring that the workforce is not being harmed by these hazards. Although this may seem the most direct and simplest approach, it will not prevent exposure and can only confirm the unwanted outcomes. Prevention of exposure, as far as reasonably possible, is the most appropriate and only fully effective way of controlling risks to health from exposure to a known hazard in the workplace.

Health surveillance can be considered part of health risk management. It requires a systematic approach for early detection of disease and follow-up to prevent progression of ill-health and also hopefully to prevent further exposure to others. It can also be valuable for confirmation that an effective health control programme is in place such as audiometry (hearing testing) after implementation of a hearing conservation programme in the workplace, for instance.

This is a system used in industry to minimise or eliminate exposure to hazards. The infographic below is produced and used by the National Institute for Occupational Safety and Health (NIOSH).

Cannabis oil, the highs and lows of a potentially life-saving drug

Cannabis oil, the highs and lows of a potentially life-saving drug

Dr Simon Davis, specialist consultant, Express Medicals Ltd.

Over the past decade reports of the magical medicinal properties of cannabis oil have stimulated growing media attention.  Claims have been made about the oil’s ability to reduce pain, treat Parkinson’s disease and even cure cancer. Among all the claims and counter-claims there is a complex mix of a potentially life-saving treatment running headlong into political and legal inertia.

This has culminated in the recent heart rendering spectacle of families pleading for permission from the Home Office to allow the import and use of medical cannabis oil to treat their children’s life-threatening epileptic seizures. Yesterday, the Home Secretary announced that specialist doctors in the UK will be able to legally prescribe cannabis-derived medicinal products by autumn.

Those that meet safety and quality standards are to be made legal for patients with an “exceptional clinical need”, Sajid Javid said.

As it is a devolved matter, it will require legislative change before it is enforced in Northern Ireland

What is cannabis oil?

Cannabis oil is produced from extracts of the plant Cannabis sativa, commonly referred to as marijuana. The plant is pulped and the active ingredients recovered using a solvent extraction process. The end-product is a dark green viscous oil which is normally imbibed orally or rectally. Rectal administration is preferential as it results in a higher percentage of active ingredients being absorbed into the body.

Figure 1. Cannabis oil is a dark green viscous liquid often distributed in syringes.

The oil contains two active ingredients:



  1. The psychoactive tetrahydrocannabinol (THC) and
  2. The non-psychoactive cannabidiol (CBD).

The concentration of the two molecules is important due to their physical effects and the legality of their possession and use. When concentrations of THC fall below 0.2%, the use of the oil does not produce a ‘high’ in the person consuming it. In other words, the psychoactive effects of the compound are minimal or absent below this concentration. Due to the absence of a ‘high’ it is currently legal to possess, sell and use cannabis oil providing the THC content does not exceed the 0.2% threshold. This has resulted in a wide range of legal over-the-counter products becoming available within the UK.

Will I fail a drug test if I use cannabis oil?

Cannabis screening and drug testing normally depends on the presence of the THC metabolite 11-NOR-9-THC-9-COOH in a subject’s urine or oral fluid. Most testing programmes use a threshold concentration of equal or greater than 50ng per ml to determine if marijuana has been used by the test subject.

With THC concentrations of less than 0.2% (0.2 mg per ml) it would be highly unlikely that bodily concentrations of the metabolite could ever reach a value high enough to trigger a positive or presumptive positive test result. However, over the counter preparations are not pharmaceutical grade medicines and only have to conform with UK food safety standards. As a result, production quality may be variable, resulting in cannabis oil with unpredictable THC levels. It is, therefore, conceivable that oils could be mistakenly distributed with THC concentrations in-excess of 0.2 %.

As it is impossible to distinguish between positive results caused by poor production processes and deliberate marijuana use, it may be advisable to avoid cannabis oil may be advisable unless you are confident of the products THC concentration.

Does cannabis oil have medicinal properties?

Due to the psychoactive effects of THC, clinical studies have focused on CBD medications. At the beginning of this year, medical publication the Lancet published a US-based study highlighting the exciting potential for the application of this approach. The study investigated the effects of CBD administration on suffers of the debilitating form of epilepsy known as Lennox-Gastaut syndrome. The study reported a reduction in seizures, relative to a placebo group, of nearly 20%. This is statistically significant and could greatly improve the quality of life of those suffering from the syndrome. The paediatric research group at Massachusetts General Hospital has now entered the next phase of the study to identify any possible long-term side effects caused by prolonged CBD administration.

More startling results were reported on the effects of seizures experienced by Dravet syndrome sufferers. The Epilepsy Society Journal in late 2017 reported that the use of CBD reduced seizures in a 6-year-old child from 300 per month to fewer than 3. This is particularly significant as the child had become resistant to other forms of anti-seizure medications and had no alternative forms of treatment.

Although this limited research shows great promise, the use of CBD alone is not effective in all cases. Certain individuals appear to respond to cannabis oil only when it contains both CBD and THC at levels greater than 0.2%. This means the cannabis oil preparations used by such individuals may require THC concentrations sufficient to result in psychoactive effects.

This appears to be the true in the case of 12-year-old Billy Caldwell recently made the news when his medicinal cannabis oil preparation was confiscated by customs when he entered the UK. Billy is one of the individuals who is non-responsive to CBD alone and requires a preparation which combines CBD with low levels of THC in-order-to control his seizures. Although the concentration of THC was low enough to prevent any obvious psychoactive effects it was above the legal threshold of 0.2%. This was sufficient for customs to confiscate the preparation as the family entered the UK.

Why was it illegal to prescribe cannabis oil to treat seizures?

You may note that the studies referred to in this article have taken place outside the UK, this is not a coincidence. UK researchers had been frustrated by the ‘Catch 22’ scenario created by British regulations and drug classification. Currently psychoactive drugs with known clinical benefits are classed as Schedule 2. This includes powerful compounds such as Heroin (diamorphine), morphine and cocaine. Schedule 2 compounds can be prescribed by doctors to patients if they can demonstrate a clinical need. Researchers can also administer these drugs as part of research programmes and clinical trials. Compounds that are psychoactive but have no proven clinical benefit are classed as Schedule 1, this includes LSD and cannabis. Schedule 1 compounds cannot be prescribed by doctors or used in clinical trials without a specific Home Office licence. Such c are rarely issued. Thus, as cannabis oil has no clinical evidence of efficacy researchers are effectively barred from carrying out clinical trials to determine if there is any clinical efficacy.

UK researchers in this area are further frustrated by clear contradictions in current UK legislation. This is highlighted by the example of cannabis-based drug Sativex. Despite containing high levels of THC (around 50%) it can be legally prescribed by UK Doctors to treat MS and used in clinical trial without a Home Office licence. The obvious question is how can Sativex be legally used whilst Billy Caldwell’s oil preparation remains illegal? The answer is quite simple, in April 2013 the Home Office arbitrarily changed the classification of Sativex from Schedule 1 to Schedule 4. This resulted in the absurd position that THC now straddles more than one drug schedule classification.

Further contradictions and confusion in the legislation exist. For example, if you are a European resident in a country where medicinal cannabis is permitted, you can legally import prescribed cannabis oil with high THC concentrations under article 75 of the Schengen agreement. This means that a German child sitting next to Bill Caldwell could have legally walked through UK customs with the same cannabis oil confiscated from Billy’s mother.

The obvious contradictions and confusion in the current UK law have combined with growing public pressure. This resulted in an announcement by the Home Secretary that the Home Office will undertake an urgent review into current legislation surrounding medical cannabis and their associated preparations, and yesterday’s announcement.
