Yes, thanks, Minister. We launched the recovery plan in April 2022. In the period between now and then, we've seen 2.3 million referrals onto waiting lists. So, that's for treatment or out-patient, and the rate of referral continues to increase. Our overall waiting list in that period of time has remained fairy stable; I think it's a sort of 1 per cent increase in total terms. So, we've been able to, I suppose, manage what's come onto the list over that period of time, but unable to reduce the total size of the waiting list. We're seeing, on average, an increase of about 20,000 patients per month compared to pre-pandemic levels, in terms of referrals, when you compare to 2019-20. So, that's a very challenging position.
Within the recovery plan itself, we set out in 2022 that we would seek to increase activity to levels of 110 per cent of pre-pandemic, so a 10 per cent increase on 2019-20 activity levels, which would have then allowed us, based upon plans, to bring down the waiting list in total and deliver the two-year and 52-week waiting time targets. In that period, we've seen out-patient activity increase by around 12 per cent. So, we've managed the out-patient backlog to a large extent, but, in terms of the activity going through theatre—so, procedure activity—that is still 6 per cent below the 2019-20 numbers. So, in essence, that's where the issue is.
There are many reasons why we've not been able to get back to that 100 per cent and then 110 per cent level. Some of it is a productivity issue. Some of it's around availability of staff to staff the theatre sessions that we've got, and we've not seen the increase in theatre sessions that we planned to increase. Others are then patient related, where we've got quite significant numbers of patients who are deemed urgent or acute coming into the system. Many of those will require in-patient episodes rather than day-case episodes, which, obviously, reduces the number on the theatre list, et cetera. So, there are a myriad of, I suppose, pandemic issues that are playing out now in terms of the waiting list.
We have seen a reduction in wait times. So, the number of patients waiting over two years is down by around 60 per cent over the period. It's not where we wanted to be. I think I've been in a couple of these committees where we've talked about the waiting list reductions not getting to where we wanted to get to. In essence now, only 3 per cent of pathways are over two years, so 97 per cent of patients are being seen, treated and discharged from the pathway within the sort of two-year period. And the average wait in Wales is now down to around 20 weeks. At peak, that was 29 and, when we launched the plan, that was 24.
So, there's been progress—not where we would expect it to be—and the challenge now with the budget position is how we utilise the budget that we've got to really drive productivity. And as the Minister alluded to previously, the value and sustainability board is very much focused on the opportunities for productivity, and that will be within theatres and other areas.
