Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, how many recorded cases there have been of each type of nosocomial condition by NHS England in each year since 2000.

Public Health England (PHE) was established in 2013. The rate of infection for the nosocomial conditions since 2013 is shown in the table below.

Table 1 - Counts of trust-apportioned infections by financial year since April 2013

PHE retains data collected by the Health Protection Agency since 2007.

Surveillance of Clostridium difficile infection began in 2007, trust-apportioned MRSA in 2008, trust-apportioned MSSA in 2011 and E. coli in 2013. Cases are published according to trust apportionment on a financial year basis, although for MRSA this has been superseded by an assignment process based on post-infections reviews since April 2013. Data collected prior to PHE’s formation is found in table 2.
