The chart above shows (provisional) monthly numbers of NHS Hospital and Community Health Service (HCHS) staff by contract type. Contract type is either locum (i.e., a doctor who is standing in for an absent doctor, or temporarily covering a vacancy) or non-locum. The data exclude primary care staff and represent the number of full-time equivalent (FTE) staff.
The number of NHS hospital doctors has increased by 8,609 between September 2009 and January 2015. The change in numbers follows a seasonal pattern where the number of doctors beginto increase from around July/August as newly qualified staff members join the workforce, reaching a peak in the winter, followed by a decline as staff leave the workforce.
The monthly HCHS workforce statistics (provisional) is published by the Health & Social Care Information Centre (HSCIC) using data collected from electronic staff records (ESR). Within the ESR, there is an assignment type of contract field to denote who is or is not a locum.
