Patient outcomes following emergency admission to hospital for COVID-19 compared with influenza

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 (incidence rate ratio 1.30, 95% CI 1.23 to 1.37).

We concluded that patients admitted for COVID-19 were more likely to die, more likely to stay in hospital for over 10 days and interact more with primary care after discharge, than patients admitted for influenza. However, readmission rates were similar for both groups. These findings, while situated in the context of the first wave of COVID-19, with the associated pressures on the health system, can inform health service planning for subsequent waves of COVID-19, and show that patients with COVID-19 interact more with healthcare services as well as having poorer outcomes than those with influenza.

The findings relate to 2020, a period before Covid-19 vaccination began and when different variants of SARS-CoV-2 were circulating in the UK. We aim to update the analysis to see how Covid-19 outcomes have changed since that period compared to outcomes from influenza.

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...

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...

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...
