Impact of vaccination on Covid-19 hospital admissions in England

Our new article in the Journal of the Royal Society of Medicine examines the impact of vaccination on hospital admissions for Covid-19 in England during 2021. Covid-19 vaccination substantially reduced the risk of hospital admission, particularly in people who received three doses.  We used data over a whole calendar year covering multiple variants of SARS-CoV-2, variable case rates and changing vaccine uptake. 

This provides a population-level overview of the impact of vaccination that is not possible from studies over a shorter period. Using primary diagnosis of Covid-19 as the inclusion criteria increases the specificity of our study by excluding those co-incidentally Covid-19 positive but admitted for another reason. We excluded “ghost patients” that can bias the estimates of vaccine effectiveness. 

We report a dose-dependent effect of vaccination, as well as waning of the effectiveness of each vaccination dose, highlighting the value of booster vaccinations. Our analysis supports an ongoing programme of booster vaccinations, especially in the elderly and risk groups.

The Hidden Cost of Cheaper NHS Contracts: Losing Community Trust

NHS budgets are under considerable pressure. It is therefore unsurprising that many NHS Integrated Care Boards (ICBs) In England will aim to prioritise price in contract awards, But this approach is a significant threat to community-centred healthcare. While competitive tendering is a legally required, an excessive focus on costs in awarding NHS contracts risks overshadowing key factors such as established community trust, local expertise, and the long-term impact on continuity of care. This shift towards cheaper, often external, commercial providers threatens to cut the links between communities and their local health services. The argument that competitive tendering is solely about legal compliance, and not cost, is undermined by the very nature of such tendering, which by design encourages the lowest bid. This approach risks eroding the social fabric of local healthcare provision, where established relationships and understanding of specific community needs are essential. Establishe...

MPH Student Presentations on the NHS Care.Data Programme

As part of a session on primary care data in the Health Informatics module on the Imperial Master of Public Health Programme, I asked students to work in two groups to present arguments for and against the NHS Care.Data programme. Care.Data is an NHS programme that will extract data from the medical records held by general practitioners (GPs) in England. The Care.Data programme takes advantage of the very high level of use of electronic medical records by GPs in England. After extraction, data will be uploaded to the NHS Health and Social Care Information Centre (HSCIC). The data will then be used for functions such as health care planning, monitoring disease patterns and research. The programme has been controversial with proponents arguing that the programme will bring many benefits for the NHS and the population of England; and opponents arguing it is a major breach of privacy. You can view the two presentations to help inform you further about these arguments: Arguments fo...

Talking to Patients About Weight-Loss Drugs

The use of weight-loss drugs such as GLP-1 receptor agonists (e.g., semaglutide, tirzepatide) has increased rapidly in recent years. These drugs can help some people achieve significant weight reduction, but they are not suitable for everyone and require careful counselling before starting treatment. By discussing benefits, risks, practicalities, and  uncertainties, clinicians can help patients make informed, realistic decisions about their treatment. Key points to discuss with patients 1. Indications and eligibility These drugs are usually licensed for adults with a specific BMI. They should be used alongside lifestyle interventions such as dietary change, increased physical activity, and behaviour modification. 2. Potential side effects – some can be serious Common adverse effects include nausea, vomiting, diarrhoea, and abdominal discomfort. Less common but more serious risks include gallstones, pancreatitis and visual problems. Patients should know what to watch for a...
