Dr. Maura Young:

I will answer that. When the concerns were highlighted to us by the local consultant at that time, who said he was coming across abnormal prescribing patterns and was not happy with some of the diagnoses being made, we said that what we needed to do was take a 10% random sample to see if the issues were isolated or widespread across the whole caseload. At that time, there were just over 500 cases open so we took a 10% sample, which is approximately 55 cases.
