In March 2020, in response to a request from the Secretary of State for Health and Social Care, NHS England and NHS Improvement commissioned a temporary service in response to the COVID-19 pandemic.
The COVID-19 Clinical Assessment Service (CCAS) was created by the South Central and West Commissioning Support Unit as part of the National Pandemic Flu Service and was hosted and managed by the South Central Ambulance Service NHS Foundation Trust (SCAS).
The service, which was rapidly established and deployed, was operational from late March 2020 until May 2021.
Patients accessed CCAS via the NHS 111 service. Patients with COVID-19 symptoms who contacted NHS 111 were triaged into three categories:
- Patients with severe COVID-19 symptoms requiring urgent hospital admission
- Patients with COVID-19 symptoms requiring further assessment
- Patients with mild COVID-19 symptoms who were given guidance to manage their symptoms, and with the advice to consult NHS 111 again should their condition deteriorate
Those patients requiring further assessment were referred to CCAS for a remote, telephone-based consultation with a clinician. Following this assessment, these patients were either reclassified as able to manage their symptoms, requiring hospital treatment or were referred to their own GP for ongoing monitoring.
