Flu vaccine may reduce the risk of death and hospital admission in people with type 2 diabetes

The flu vaccine may reduce the likelihood of being hospitalised with stroke and heart failure in people with type 2 diabetes, according to new research. The study from Imperial College London also found the patients who received the influenza vaccination had a 24 per cent lower death rate in the flu season compared to patients who weren't vaccinated.

The team, who published their findings in CMAJ (Canadian Medical Association Journal) studied 123,503 UK adults with type 2 diabetes between 2003 and 2010. Around 65 per cent of these patients received the flu vaccine. We found that, compared to patients who had not been vaccinated, those who received the jab had a 30 per cent reduction in hospital admissions for stroke, 22 per cent reduction in heart failure admissions and 15 per cent reduction in admissions for pneumonia or influenza. Furthermore, people who were vaccinated had a 24 per cent lower death rate than patients who were not vaccinated.

We also found a 19 per cent reduction in hospital admissions for heart attack among vaccinated type 2 diabetes patients during the flu season, but this finding was not statistically significant.

Dr Eszter Vamos, lead author of the study from the School of Public Health at Imperial, said: "Most flu deaths every year occur in people with pre-existing health conditions such as type 2 diabetes. This study suggests the vaccine may have substantial benefits for patients with long-term conditions. Not only might it help reduce serious illness such as stroke - and possibly heart attack - in high-risk individuals, but it may also reduce the risk of death in the flu season. Currently more than one-third of people with diabetes do not receive their flu vaccine year-by-year in England. By increasing the number of people receiving influenza vaccine annually, we could further reduce the risk of severe illness not addressed by other measures."

Type 2 diabetes results in a person being unable to control their blood sugar properly and affects around 2.7 million people in UK. People with the condition are at high risk of cardiovascular disease, which includes heart disease and stroke, possibly due to high blood sugar levels damaging blood vessels. Furthermore, flu infection has been found to increase the risk of heart attack or stroke in patients with cardiovascular disease, although scientists are unsure why.

In the UK the NHS offers the annual flu vaccine to children and adults with underlying health conditions such as type 2 diabetes, as well as to all over-65s and pregnant women.

Professor Azeem Majeed, co-senior author from the School of Public Health at Imperial added: "There are few studies looking at the effectiveness of the influenza vaccine in people with diabetes. Although there have been questions surrounding the effectiveness of the flu vaccine in recent years, this research demonstrates a clear advantage for people with diabetes. The findings of the study illustrate the importance of flu vaccine in reducing the risk of ill-health and death in people with long-term conditions. The flu vaccine is available free to these patients from GPs and pharmacists, and patients with diabetes should ensure they receive the vaccine every year."

In the study, we looked at a representative sample of patients with type 2 diabetes in England. We then tracked these patients over a seven year period, and monitored the number of hospital admissions in this patient group for heart attack, stroke, heart failure, pneumonia, influenza. We also looked at the number of deaths. We then adjusted their figures for demographic and social factors, as well as existing health conditions.

The research was supported by the National Institute of Health Research North West London Collaboration for Leadership in Applied Health Research and Care Scheme and the NIHR Imperial Biomedical Research Centre.

Example ADHD Referral Letter

Dear Dr, I am writing to refer a 28-year-old male patient of mine, Mr [Patient's Name], for assessment for the diagnosis and treatment of Attention Deficit Hyperactivity Disorder (ADHD). After a thorough clinical assessment, I believe that Mr. [Patient's Name] meets the criteria for adult ADHD as outlined in NHS guidance for primary care teams in SE London. Mr [Patient's Name] has been under my care for XX years and, during this time, he reports several symptoms (greater than five symptoms in total) consistent with ADHD in adults that have been present for more than six months. These symptoms include difficulties in focusing, following through on tasks, hyperactivity, forgetfulness, impulsiveness, restlessness, and irritability. Mr [Patient's Name] also reports being easily distracted, struggling with time management, organisation, and completing tasks efficiently. Many of Mr [Patient's Name]'s symptoms have been present since he was under 12 years old; and have

1. Measles The UKHSA has warned that unless MMR vaccination rates improve, London could experience a large measles outbreak. Measles is potentially a very serious illness with important complications - but is preventable though vaccination.  Please ensure patients and their families are up to date with their vaccinations. Please also check the vaccine status of new patients - particular migrants - and enter details onto the medical record of any vaccines given elsewhere. https://www.gov.uk/government/news/london-at-risk-of-measles-outbreaks-with-modelling-estimating-tens-of-thousands-of-cases 2.

Why we need to put an end to the GANFYD culture in the UK

One of the causes of increased workload in general practice are the many requests that doctors get for letters, reports and forms from patients or from external organisations. It’s now so common that doctors have coined a term for it: GANFYD – Get A Note From Your Doctor.  It’s seems that large sections of society can’t function without these “letters from doctors”. Instead of using common sense or employing their own clinical advisers, external organisations make repeated requests to NHS doctors for letters which are often not at all needed. Often the worst offenders come from the public sector – e.g. universities who seem to look upon NHS general practice as a source of free occupational health advice for their students. Universities never – of course - offer to pay for this advice they get from NHS GPs. Instead, university requests will come with a mealy-mouthed statement that any fee is the responsibility of the student. Like doctors are going to impose heavy fees on impoverished s
