Laparoscopic bariatric surgery in England

A study by Elaine Burns and colleagues published in the BMJ describes the large increase in NHS laparoscopic bariatric surgery operations observed in recent years, with an increase from 238 operations in 2000 to 2543 in 2007. Recent years have also seen large increases in NHS prescribing and spending on drugs for obesity. For example, a study published in the Journal of Public Health Medicine reported that between 1998 and 2005, Orlistat prescriptions in England rose 36-fold from 17,880 to 646,700 and their total cost increased by over 35-fold to £27 million. Sibutramine prescriptions rose from 53,393 in 2001 to around 227,000 in 2005, a 4-fold increase, at a cost of £11 million in 2005.Despite this increased spending on medical and surgical NHS interventions, rates of obesity continue to increase inexorably and around 25% of adults in England are now considered to be obese, with a BMI of 30 or greater.The failure of medical treatments for obesity is further illustrated by the subsequent withdrawal of Rimonabant and Sibutramine because of concerns about their safety. Although medical and surgical treatments have an important role in the management of obesity, particularly in some high risk groups, the key to tackling obesity lies in wider societal approaches, involving joint working between the NHS, local and national government, and the private sector.

What is the difference between primordial prevention and primary prevention?

Primordial prevention and primary prevention are both crucial strategies for promoting health, but they operate at different levels. Primordial prevention aims to address the root causes of health problems and improve the wider determinants of health. It focuses on preventing the emergence of risk factors in the first place by tackling the underlying social, economic, and environmental determinants of health. This involves broad, population-wide interventions such as: Policies that promote healthy food choices: Think about initiatives like taxing sugary drinks to discourage unhealthy consumption, or providing subsidies for fruits and vegetables to make them more accessible. Urban planning that prioritises well-being: This could include creating walkable neighborhoods with safe cycling routes, ensuring access to green spaces for recreation and relaxation, and designing communities that foster social connections. Social programs that address inequality: Initiatives aimed at reducing pov...

UK Covid-19 Inquiry - The Importance of a Strong Primary Healthcare System

In my witness statement for Module 10 of the UK Covid-19 Inquiry, I discuss the pandemic's impact through from the perspectives of primary care and public health, drawing on my extensive experience as a senior academic at Imperial College London and as a practising GP and NHS Public Health Specialist. I emphasise that the pandemic disproportionately affected people who were clinically vulnerable, the disabled, ethnic minority communities and those living in deprived areas. The pandemic highlighted how structural inequalities, multigenerational housing, and employment in high-risk frontline roles exacerbated health disparities. My statement also critiques the weakening of public health infrastructure - particularly for the control of infectious diseases - and the lack of integrated health data systems to identify at-risk groups such as the clinically vulnerable. I also advocated for a more robust preventive healthcare model that prioritises community-based primary care ...

Relevance Over Recall: Rethinking How AI Uses Clinical Data

Our article in the Journal of the Royal Society of Medicine argues that safe and effective AI in healthcare must incorporate mechanisms that emulate human judgement - down-weighting old, inaccurate or superseded information and prioritising what is recent, clinically relevant and reaffirmed - so that AI supports, rather than disrupts, high-quality patient care. Clinicians constantly revise, reinterpret and filter past information so that only what is relevant, accurate and timely shapes present-day management decisions; medical records function as dynamic “working tools” rather than fixed archives. By contrast, many AI systems lack this capacity for selective forgetting and often treat all historical data as equally meaningful. This can lead to outdated or low-confidence diagnoses being repeatedly resurfaced, persistent labels influencing clinical expectations, and irrelevant, long-resolved events cluttering summaries and decision-support outputs. Such indiscriminate recall...
