Healthcare-Associated Infections: C. difficile (Clostridioides difficile)
\n\nThis dataset relates to healthcare-acquired C. difficile infections in patients aged 2 years and above. It includes cases where a positive specimen was collected on day 2 or earlier of admission (with day 1 being the day of admission), and where there has been no prior healthcare interaction at the same Trust in the previous 84 days.
\n\nDiagnosis is confirmed by one of the following five criteria:
\nData is broken down by Sub-ICB geography (Integrated Care Board location).
\n\n\nSurveillance of C. difficile laboratory faecal samples in England and Wales was introduced in 1990 as part of the Public Health Laboratory Service\u2019s voluntary monitoring of infectious diseases. Between 1990 and 2004, there was a rise in the number of C. difficile infections, from less than 3,000 in 1990 to more than 45,000 in 2004. Rates of C. difficile infections also rose over this time period in all age groups \u226540 years old.
\nDue to the increasing incidence of C. difficile infections, the mandatory reporting of C. difficile infection in people aged \u226565 years was introduced in England in January 2004. This was a quarterly aggregate data return reported by NHS acute Trusts comprising data on the number of toxin-positive C. difficile faecal samples. Due to the continued rise of C. difficile infections among the population aged \u226565 years, the C. difficile mandatory surveillance scheme was enhanced in April 2007 to be patient-level and to cover all C. difficile infections in patients aged 2 years and over.
\nPrior healthcare interactions were introduced in April 2017 as a means to determine any prior healthcare interactions from the same Trust. A low value is indicative of a low rate of C. difficile.
\n\nThese data do not provide a basis for decisions on the clinical effectiveness of infection control interventions in individual Trusts: further investigations considering potential confounders would need to be undertaken before this could be done. Nor do these data provide a basis for comparisons between acute Trust or SICBLs. Rate information, using rate calculations as currently defined, is not appropriate for comparison. The counts of infections have not been adjusted to give a standardised rate considering factors such as organisational demographics or case mix. Rate information is of use for comparison of an individual organisation over time.
\n\u2018All reported cases\u2019 refers to all toxin-positive results for C. difficile infections that are detected by the Trust whose laboratory processed the specimen. It is important to note that this does not necessarily imply that the infection was acquired there. Confidence intervals for rates are not currently calculated because appropriate methods for comprehensive coverage are being assessed.
\nCases that the UKHSA\u2019s HCAI Data Capture System attributes to a commissioning hub (such as the national commissioning hub, 13Q, or one of the regional Health & Justice commissioning hubs) are not featured in sub ICB Location dashboards but they do still contribute to the highest spatial level\u2014the England national total. This means the England case total & rates may be slightly higher than the sum of all sub ICB Location cases & rates.
\nIMPORTANT NOTE: SICBL calculations for the period between January 2021 and January 2022 have been based on SICBL boundaries. As such, some SICBLs may experience higher or lower rates than expected due to this change. Those SICBLs affected are: Bassetlaw, Glossop, East Leicestershire and Rutland, Lincolnshire, Cambridgeshire and Peterborough, Birmingham and Solihull, Black Country and West Birmingham, and Oundle.
