Annual epi update on bloodstream infections and C. difficile infections in England.

Continuing worrying trend of increasing rates of most of these infections, especially for community-onset cases

My colleague Olisa has a new article out in Eurosurveillance looking at the epidemiology of Gram-neg BSI in England.

Loads of interesting data: incidence, mortality rates and CFRs for E. coli, Klebs and P. aeru.

Does the incidence of common bloodstream infections vary across deprivation level & ethnic groups in England and can differences be quantified?

Key public health message for the article: What did you want to address in this study and why? Socioeconomic inequalities exist across infections. We wanted to assess if the incidence of common bacteraemia varies across deprivation level and ethnic groups in England and to quantify any differences. The aim was to identify high-risk population groups and areas for public health interventions. Between 2018 and 2022, we investigated bacteraemia caused by Escherichia coli, Klebsiella and Pseudomonas aeruginosa bacterial species as well as by meticillin-susceptible and resistant Staphylococcus aureus (MRSA, MSSA). What have we learnt from this study? In England, bacteraemia from E. coli, Klebsiella spp., P. aeruginosa and particularly MRSA disproportionately affected people from the Black and Asian ethnic groups, after adjusting for age. In contrast, the White ethnic group had higher incidence of community-onset MSSA bacteraemia. People living in the 20% most deprived areas of England also had higher age-standardised incidence of all bacteraemia (176.7 compared to 91.7 per 100,000 population per year in the 20% least deprived areas), and especially MRSA bacteraemia. What are the implications of your findings for public health? Public health agencies and health research organisations should consider stratifying their analyses by ethnicity and deprivation to identify and quantify health inequalities. Further studies including qualitative research is required to identify the root causes of these concerning inequalities in the incidence of bacteraemia caused by different pathogens, so that adapted measures can be designed to mitigate them.

The big question is: why do we see these sad inequalities?

Difficult to say: complex intersection of factors.

People living in more deprived areas and certain ethnic minorities tend to be more affected by:
💔 predisposing comorbidities
💸 poverty
🏫 low educational attainment
⚕️barriers to healthcare

In England, people from ethnic minorities or living in more deprived areas are disproportionately affected by bloodstream infections.

We've shown this with our latest study, just been published on @eurosurveillance.org.

Note the importance of lack of judgement here. If you're going to interact w/folks who haven't vaccinated their kids, being assholes to them isn't a great strategy. You don't know their reasoning. /1

📊 What do we know about bloodstream infections in #CriticalCare units in England between 2017 and 2023?

Our new study used national #surveillance to find out.

The incidence of CCU-associated BSI surged by 75% during the first year of the COVID pandemic. Why?
