To ask the Scottish Executive, further to the answer to question S2W-11273 by Mr Andy Kerr on 2 November 2004, how many cases of (a) MRSA and (b) other forms of staphylococcus aureus there have been in (i) 2004 and (ii) 2005.
A national mandatory healthcare associated infection surveillance system was introduced in 2001 to monitor MRSA bacteraemias (blood infections). This system also collates other
Staphylococcus aureus bacteraemias (methicillin-sensitive, or MSSA strains). The surveillance is operated by Health Protection Scotland (HPS) and it produces quarterly reports. From January 2005 a new system for reporting was introduced in Scotland and this has resulted in more accurate and complete reporting of MRSA bacteraemias.
These reports show that from January 2001 to September 2004 there were 3,432 episodes of MRSA bacteraemia and 4,429 episodes of MSSA bacteraemia. The total number of episodes of all Staphylococcus aureus bacteraemia (resistant and non-resistant) for this period is therefore 7,861.
Table 1: Episodes of Staphylococcus aureus bacteraemia between January 2001 and September 2004: methicillin-resistant (MRSA) and methicillin-sensitive (MSSA) strains
Period | MRSA | MSSA |
2001 | 885 | 1,033 |
2002 | 938 | 1,214 |
2003 | 875 | 1,259 |
To September 2004 | 734 | 923 |
Total | 3,432 | 4,429 |
In preparing this answer, it has come to my notice that the table provided in the answer to question S2W-11273 on 2 November 2004 incorrectly gives a total figure of 3,942 episodes between 2001 and June 2004. As the main text of the answer makes clear, the correct total was 3,042 episodes.
