April 2006 to March 2007
NHS inpatient and outpatient component waiting times were published from 1997 until March 2010 and used to measure the waiting times for the first outpatient and inpatient stages of a patient’s treatment pathway. Since 2009, Welsh Government has published monthly data on NHS Referral to Treatment Times, which measures the total waiting time from GP referral to treatment and this is now the main source of information on NHS waiting times.
