Under the Joint Escalation and Intervention Arrangements, Welsh Government officials meet with Audit Wales and Healthcare Inspectorate Wales at least twice a year to discuss the overall position of each health board, NHS trust and Special Health Authority in respect of quality, governance, service performance and financial management.  A wide range of information and intelligence is considered to identify any issues and inform the assessment.
