The NPSA has published statistics on patient safety incident reports 

The data in the March 2010 reports cover patient safety incidents that took place between 1 April 2009 and 30 September 2010 and were reported to the National Reporting and Learning System (NRLS) by 31 December 2009.

 The key issues are as follows:

• The number of reported patient safety incidents that resulted in death has fallen, against a backdrop of increased awareness, learning and reporting by NHS organisations across England month on month, the number of trusts that have submitted regular reporting has increased.
• The number of patient safety incidents reported to the NPSA as having resulted in death has decreased from 1,856 to 1,160 compared to the same period last year.
• The number of reported cases that resulted in severe harm to the patient fell from 3,643 to 2,412.  

From these, the most commonly reported incident type is patient accident (31 per cent/154,538 incidents); treatment, procedure (10 per cent/51,393 incidents); and medication (10 per cent/50,950 incidents).
