 One of my educational roles is update staff in my medical practice about topical public health issues in our weekly clinical meeting. In the most recent meeting, I gave an update on polio in London, including some key facts that health professionals need to understand. 1. Understand the difference between the two types of polio vaccines: inactivated and live. The inactivated polio vaccine has been used in the UK since 2004. Once polio has been eradicated from a country, it is safer to use the inactivated vaccine. 2. Check each patient’s polio vaccination status and encourage those patients who are not vaccinated or only partly vaccinated to receive a full course of vaccinations. Ensure that vaccine status is recorded on the patient’s electronic medical record. 3. Support the booster programme for children aged 1-9 years old that is currently being rolled out across London. Address vaccine hesitancy and any concerns about vaccination in parents sympathetically and aim to understand...

I was explaining to a student recently how we did literature searches in the 1980s and 1990s. We had to look up articles in a printed copy of Index Medicus, and then pushed a trolley around the library to collect the journals so we could photocopy the articles. There was an incredulous look in her eyes. We had to pay for the photocopies, which made us very selective about the articles we used in our literature reviews.  And when we got to the photocopier, we had to hope that it had not broken down or that the queue to use it was too long. Arriving well before library closing time was also important. Online articles did not exist then and sometimes we had to wait for weeks for articles to arrive using the Inter-Library Loan Service if they were not in the library’s own collection. Eventually, printed copies of Index Medicus were replaced by a CD-ROM version (which you have to book a slot in advance to use) and then eventually by online bibliographic databases. And now, we have immed...

Our recent study in the journal Thorax examined patient outcomes following emergency admission to hospital for COVID-19 compared with influenza. We used routinely collected primary and secondary care data. Outcomes, measured for 90 days follow-up after discharge were length of stay in hospital, mortality, emergency readmission and primary care activity. The study included 5132 patients admitted to hospital as an emergency, with COVID-19 and influenza cohorts comprising 3799 and 1333 patients respectively. Patients in the COVID-19 cohort were more likely to stay in hospital longer than 10 days (OR 3.91, 95% CI 3.14 to 4.65); and more likely to die in hospital (OR 11.85, 95% CI 8.58 to 16.86) and within 90 days of discharge (OR 7.92, 95% CI 6.20 to 10.25). For those who survived, rates of emergency readmission within 90 days were comparable between COVID-19 and influenza cohorts (OR 1.07, 95% CI 0.89 to 1.29), while primary care activity was greater among the COVID-19 cohort (incide...

  Why are so many people coming down with Covid again? The current wave of Covid-19 infections is being caused by highly infectious subvariants (BA.4 and BA.5) of the Omicron variant that entered the UK in late 2021. These subvariants are more infectious than the previous variants of the coronavirus that the UK has faced. They are also more likely to cause reinfections. Other factors increasing the number of infections include greater mixing of people now that Covid-19 measures in the UK have ended and reduced protection from infection from vaccines because many people are more than six months since their last Covid-19 vaccination.   Are the new variants worse than the other variants? Although they are more infectious than other variants, the new subvariants of Omicron do not cause more severe disease and on average, they probably cause a milder illness. However, because of the very large number of infections caused by these subvariants, some people will have a serious...

Despite the very low risk of seroconversion, occupational HIV exposure is a very stressful situation. Our new article in the Journal of the Royal Society of Medicine provides guidance on how such exposures should be managed to minimise risks and improve health outcomes for staff exposed to contaminated body fluids.  Careful risk communication can help in addressing anxiety. Pre-Exposure Prophylaxis (PEP) is seldom indicated for occupational exposures if the index case is of unknown HIV status, as the transmission risk is very low. PEP is indicated to reduce the transmission risk following high-risk incidents – exposures where the index case is known to be HIV-positive with a detectable viral load – and is most effective if started promptly.

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 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...

During the COVID-19 pandemic, health systems globally shifted towards treating COVID-19 infection in adults and minimising use of health services for other patients, including children and young people (CYP), who were less susceptible to severe COVID-19. In March 2020, the NHS recommended remote triaging before any face-to-face contact to reduce infection risk.  The UK Government announced a nationwide lockdown in England from 23 March 2020, and the public was advised to stay at home to limit transmission of COVID-19 and avoid strain on health resources. GPs were asked to prioritise consultations for urgent and serious conditions, and suspend routine appointments for planned or preventive care.  Children’s access to primary care is highly sensitive to health system changes. We examined the impact of COVID-19 on GP contacts with children and young people (CYP) in England. We used a longitudinal trends analysis was undertaken using electronic health records from the Clinical Pra...

Recent draft guidance from NICE gives a much bigger role to exercise and weight loss in people with osteoarthritis, and painkillers such as paracetamol and strong opioids not advised. I agree that the aims of the new draft NICE guidance on the management of osteoarthritis in primary care are good but the problem will be in providing patients with access to suitable lifestyle and exercise programmes. In many parts of England, these services are either not currently in place or have very limited capacity. As well as putting in place services with sufficient capacity, we also need to ensure there is equitable access to them, based on clinical need. We know from prior experience that it is more affluent and better educated patients who are more likely to take up these kind of lifestyle and exercise interventions. We also need to simplify clinical pathways and allow patients to refer themselves directly to services without requiring a referral from a GP. This will improve the speed of acce...

An article published in the BMJ by Allyah Abbas-Hanif, Neena Modi and myself discusses the long term implications of Covid-19 in pregnancy. Covid-19 in pregnancy increases the risk of severe complications for both mother and baby. The long term implications are unknown, but emerging signals warn of substantial public health threats. To counter high vaccine hesitancy in pregnancy we must end the default exclusion of pregnant women from the rigorous regulated drug development process and implement systematic, long term, population-wide surveillance of infected and non-infected people. The full article can be read in the British Medical Journal . 

Thanks to Covid-19 vaccination, we have seen a substantial weakening of the link between Covid-19 infections and hospitalisations / deaths in the UK. But we don't yet know how well this protection from serious illness and death will persist in the longer-term. We are also seeing "vaccine fatigue" set in with many people not keen on booster vaccines. For the UK, the future challenges will include determining how frequently and in what groups Covid-19 booster vaccines are needed; ensuring a high take-up of vaccinations in all eligible groups; and having vaccines that are updated when necessary to protect against new variants. We have already had one additional booster vaccination programme in the UK this year; which targeted people 75 and over, residents of care homes, and people who are immunocompromised. A larger booster programme is planned for later this year that will target a wider range of people, including NHS staff. Although some people are very optimistic about th...

Earlier this month, a case of Monkeypox was reported in London, followed by reports of further cases in the UK and in many other countries. Understandably, people are anxious whenever an outbreak of an unusual infectious disease occurs, likely more so because of their experiences during the Covid-19 pandemic. Although we need to take the disease seriously, Monkeypox is much less of a threat to global health than Covid-19 and won’t have the same impact on societies or lead to the type of control measures we have seen for Covid-19 over the past two years. The virus that causes Monkeypox is found primarily in small animals, like rodents, in parts of West and Central Africa – but was first identified in monkeys (hence the name). It can sometimes spread to humans and because of international travel, then spread to other parts of the world. But unlike Covid-19, which is easily transmissible and has caused huge waves of infection globally, Monkeypox spreads much more slowly, requiring close c...

Whether it be a simple telephone call or more sophisticated video conferencing systems, virtual care tools have been in use in primary care settings worldwide in one form or another throughout the past two decades. Over time, these tools have grown in availability, matured in their capabilities, but played a largely supportive role as an alternative option to traditional face-to-face consultations. This all changed in early 2020 with the onset of the COVID_19 pandemic. The COVID-19 pandemic presented a unique opportunity globally which put virtual care tools at the forefront of primary care delivery. The need for social distancing to limit disease transmission resulted in virtual care tools becoming the primary means with which to continue providing primary care services. Hence, our study’s goal was to capture the spectrum of GP experiences using virtual care tools during the initial months of the pandemic so as to better understand the perceived benefits and challenges, and explore wh...

In this concise guide, Dr Sophie Farooque – a Consultant in Allergy at St. Mary’s Hospital in London and one of the UK’s leading experts on the treatment of allergic disorders – gives an excellent overview of allergies that will be a very useful guide for the public and also for health professionals.  Allergic disorders have increased substantially in prevalence in recent decades. This is shown in our personal experience as well as by research on the epidemiology of allergic disorders. When I was in school, problems such as hay fever and food allergy were all uncommon in my classmates. This in contrast to now, when many families will have a member who suffers from an allergic disorder. In milder cases, these disorders can be irritating and reduce people’s quality of life. But in more severe cases, they can lead to hospitalisation and sometimes even to death.  Hence, some knowledge of allergies and how they can be managed is very helpful to families who have a member who suffer...

Colorectal cancer is one of the most common cancers and most common cause of cancer deaths worldwide. Despite the availability of screening, disparities in survival from colorectal continue in certain ethnic minority groups. This may, in part, be secondary to low take-up of bowel cancer screening. Different ethnic groups may have different cultural and health beliefs, different levels of education, understanding and acculturation that negatively impacts upon their use of faecal testing and endoscopic procedures. In a systematic review published in the journal Perspectives in Public Health , we examined studies that had investigated ethnic differences in the uptake of colorectal cancer screening. We found that disparities in colorectal cancer screening are multifactorial and complex in their origin and that ethnicity plays an important role. Although seemingly intuitive, this is the first systematic review that summarises the association between uptake of screening in specific ethnic gr...

In the USA, over one-third of adults self-diagnose their conditions using the internet, including queries about urgent (ie, chest pain) and non-urgent (ie, headache) symptoms. The main issue with self-diagnosing using websites such as Google and Yahoo is that user may get confusing or inaccurate information, and in the case of urgent symptoms, the user may not be aware of the need to seek emergency care. In recent years, various online symptom checkers (OSCs) based on algorithms or artificial intelligence (AI) have emerged to fill this gap Online symptom checkers are calculators that ask users to input details about their symptoms of sickness, along with personal information such as gender and age. Using algorithms or AI, the symptom checkers propose a range of conditions that fit the symptoms the user experiences. Developers promote these digital tools as a way of saving time for patients, reducing anxiety and giving patients the opportunity to take control of their own health. The di...

In a study published in the journal Nicotine and Tobacco Research , we evaluated the secondary effectiveness outcomes for Quit Genius, a digital clinician-assisted cognitive behavioural therapy (CBT) intervention for smoking cessation. Adult smokers (N=556) were randomly assigned to Quit Genius (n=277), a digital, clinician-assisted CBT intervention or Very Brief Advice (VBA) to stop smoking, an evidence-based, 30-second intervention designed to facilitate quit attempts, coupled with referral to a cessation service (n=279). Participants were offered combination nicotine replacement therapy (patches and gum) tailored to individual nicotine dependence. Analyses (N=530), by intention-to-treat, compared Quit Genius and VBA at 4, 26, and 52 weeks post-quit date.  The primary outcome was self-reported seven-day point prevalence abstinence at 4 weeks post-quit date. Consecutive seven-day point-prevalence abstinence, defined as abstinent at two or more consecutive timepoints, was examined ...

The National Health Service (NHS) 111 helpline was set up to improve access to urgent care in England, efficiency and cost-effectiveness of first-contact health services. Following trusted, authoritative advice is crucial for improved clinical outcomes. In paper published in the journal PLOS ONE , we examined patient and call-related characteristics associated with compliance with advice given in NHS 111 calls.  The importance of health interactions that are not face-to-face has recently been highlighted by COVID-19 pandemic. In this retrospective cohort study, NHS 111 call records were linked to urgent and emergency care services data. We analysed data of 3,864,362 calls made between October 2013 and September 2017 relating to 1,964,726 callers across London. A multiple logistic regression was used to investigate associations between compliance with advice given and patient and call characteristics.  Caller’s action is ‘compliant with advice given if first subsequent service ...

Our new article in Lancet Infectious Diseases discusses why some migrants in Europe are at risk of under-immunisation and show lower vaccination uptake for routine and COVID-19 vaccines. Addressing this issue is critical if we are to address vaccination inequities and meet the goals of WHO's new Immunisation Agenda 2030.  We carried out a systematic review exploring barriers and facilitators of vaccine uptake (categorised using the 5As taxonomy: access, awareness, affordability, acceptance, activation) and sociodemographic determinants of under-vaccination among migrants in the EU and European Economic Area, the UK, and Switzerland.  We identified multiple access barriers—including language, literacy, and communication barriers, practical and legal barriers to accessing and delivering vaccination services, and service barriers such as lack of specific guidelines and knowledge of health-care professionals—for key vaccines including measles-mumps-rubella, diphtheria-pertussis-t...

Multimorbidity, the co-occurrence of two or more chronic conditions, is increasing in prevalence and affecting approximately a third of all adults globally. In the UK, the prevalence of individuals with four or more long-term conditions is projected to increase to 17% by 2035, compared to 9.8% in 2015. Approximately two thirds of this population will have a mental illness such as depression , which is in turn strongly associated with the incidence of a multitude of long-term conditions.  As the number of physical conditions a person increases, the odds of having a mental health disorder increase by almost double for one condition, and six times for more than five conditions. The presence of a mental health comorbidity such as depression is associated with poorer clinical outcomes and quality of life, compared to individuals with physical conditions only. In an article published in the journal PLOS ONE , we summarised the current evidence on the association between depression and un...

Throughout the pandemic, the UK’s covid-19 data systems have been guiding global as well as local policies. The well-established health information systems combined with the more recently established National Immunisation Management System in England provided timely information on infections, emergence of new variants, and the value of different interventions. But one of the most important contributions from the UK came from the ability to rapidly track vaccine effectiveness.  Vaccination is the best method for societies to reduce the severity of illness and number of deaths from covid-19; and to start to return to a more normal way of living, working , and studying.[1] But vaccination programmes need to be evidence-based, so that vaccines and healthcare resources are used appropriately, and there is equitable vaccine delivery. The covid-19 pandemic has shown the importance of data from medical records and the National Immunisation Management System in guiding national vaccinati...
