Download Bacteraemia Report for Trust B

Bacteraemia Report for Trust B
For Trust B during the past year, the significant bacteraemia are listed in the top ten
organisms list below. There has been little change since reporting from the last
quarter in the ranks. Coagulase negative staphylococci remain the most commonly
isolated organism. While some of these will undoubtedly be false positives (such
organisms are common skin organisms), the large number, approximately 45% of all
isolates, is probably a reflection of modern healthcare where we rely heavily on IV
access. These organisms commonly colonise the line and are picked up during
sampling.
These organisms from such sites can cause clinical illness, particularly in ITU or high
dependency patients. Our infection reduction target is currently aimed at improving
IV line management and it will be this marker that we will be watching over the
coming months to see if we can achieve an overall reduction in bacteraemias and
specifically of this common organism.
Our second highest organism is likely to be a reflection of urinary tract infection.
MRSA is currently at number 5, up from number 6 in the previous quarter. This
movement is probably not significant but you may view the specific information in
relation to Staphylococcus aureus or MRSA from the nationally collated information.

Key Messages
 Surveillance shows that for every 100,000 patients occupying a bed for a night
in a Welsh NHS Trust, 12 patients have an MRSA bacteraemia and 15 have an
MSSA bacteraemia.
 For every 100,000 patients spending a night in a bed in Trust B, 25 patients
have an MRSA bacteraemia and 47 have an MSSA bacteraemia.
 Rates of MRSA and MSSA for Trust X and for its major acute hospital are not
significantly different from the overall rates for Wales.
 Trend data show downward trends for both MRSA and MSSA bacteraemias in
Trust B, but they are not significant.
 Data by specialty show highest rates in ITU. The S. aureus bacteraemia rates
for all specialties in Trust B are not significantly different from any other
Trust in Wales.
