The most comprehensive and reliable estimates of productivity for the National Health Service in England are compiled by the Centre for Health Economics at the University of York. Their published series provides data from 1998/99 onwards and the latest available data relates to 2011/12, published in January 2014.
Total factor productivity, adjusted for quality change, was -1.25% in 2009/10, +3.21% in 2010/11 and +2.13% in 2011/12. This is the first time that the series had shown two consecutive years of positive productivity growth.
The Office for National Statistics (ONS) compiles a similar series for the whole of the United Kingdom, on a calendar year basis. The latest ONS results were published in January 2015 and show productivity growth rates for 2009, 2010, 2011 and 2012 as -1.3%, 0.6%, 3.5%, 0.9% respectively.
