An audit of the services will take place.
All 240 children affected by the Kerry mental health scandal will be offered compensation this month.
A promised review of medication practice across all child and adolescent mental health services (CAMHS) is to get under way on Thursday with the first meeting of the oversight group.
The commitment has been made today by Mental Health Minister Mary Butler.
A review found failings in their children's care in south Kerry CAMHS - which the HSE said it 'sincerely apologised' for at an Oireachtas committee this morning.
The non-consultant doctor at the centre of the South Kerry CAMHS scandal waived supervision when it was offered, according to the HSE.
The HSE says the audit will begin with assessing the treatment and medication of patients with ADHD.
It comes after an independent review found almost 50 children or adolescents who attended South Kerry CAMHS suffered significant harm.
An independent chairperson, consultant Dr Colette Halpin, has been appointed for the audit.
HSE Chief Operations Officer Anne O' Connor said doctor supervision should be mandatory:
