Health Minister Jonathan Coleman says more nurses are being trained in specialised health care, which is speeding up care for patients.
There are now 1449 clinical nurse specialists across 20 District Health Boards, up 6 percent from last year.
The number has nearly doubled from 744 in 2007.
Nurse specialists are working in almost every field of practice, including mental health, care of the elderly, orthopaedics, paediatrics, gynaecology, cardiology and emergency care, as well as forensics and eating disorders.
He says a new training programme for nurses performing endoscopies will help to reduce waiting times for the procedure. It will be available in 2016.
