NCAS statistics

Our latest statistical report is about use of exclusion and suspension from work amongst doctors and dentists in England, based on data to 31 March 2014. This continues a series of reports on suspension and exclusion use which can be found on our Publications page. Our latest report uses the same methods and data sources as earlier reports and shows trends over nine years. 

In brief:

  • performers list suspensions have fallen since 2010 but use of MHPS exclusions is rising
  • during 2013-14, 155 new MHPS exclusion episodes started in England, and 33 new Performers List suspensions
  • an estimated 120 years of doctor/dentist work were lost in 2013-14 because of suspension or exclusion from work
  • for PL suspensions, list removal was the most common outcome for episodes ending in 2013-14 (35%)

  • for MHPS exclusions, return to work with restrictions was the most common outcome (30%). 

  • over nine years 2005-06 to 2013-14, 12% of PL suspensions ended with unrestricted return to work, compared with 21% of MHPS exclusions.


Publication plan for NCAS statistics

Statistics on casework activity and suspension/exclusion from work, previously released 6 monthly, are now being released annually. 2012/13 and 2013/14 statistics on casework activity will be released shortly.


Publication of a two-yearly report looking at how concerns about professional practice are associated with:

  • age
  • gender
  • place of qualification
  • ethnicity  

is also planned for publication shortly.

NCAS is guided by the Code of Practice for Official Statistics in its production and release of operational and other statistics. To maintain confidentiality, NCAS does not release statistics which risk the identification of referred practitioners’ identities. 


Where researchers would like to see further analyses of reported statistics, it may be possible for NCAS to supply them, provided resource implications are not excessive. Release will also depend on the following conditions being met:


  • release must not breach NCAS conventions to protect confidentiality
  • analysis must be for a dataset already reported on. The results of the new analysis can then be seen as consistent with other published analyses
  • it is the user's responsibility to interpret the data and carry out any necessary significance testing.


Evaluation and research generally

NCAS work has always been informed by a programme of evaluation, research and development. For example, commissioned research by the Office of Health Economics and the Health Economics Research Unit, published June 2010, used a discrete choice experiment with senior NHS managers to explore the packages of NCAS services which are most highly valued by the NHS. This and other research is guiding NCAS as it works towards becoming a self-funding organisation.


Evaluation and research activity seeks to ensure that NCAS has the right information available at the right time to assess and demonstrate its effectiveness, to learn about and improve its work and to generate knowledge which will assist the NHS to respond effectively to performance concerns. See Publications for more information.
