Quality-adjusted public service healthcare productivity saw a fall of 25.6% in the financial year ending (FYE) 2021 (running from April 2020 to March 2021) because of the effect of the coronavirus (COVID-19) pandemic, after small declines in the previous two financial years.
Goods and services provided to support healthcare services in England through the coronavirus pandemic (such as additional personal protective equipment and NHS Test and Trace) was the main driver of the 24.2% growth in inputs in FYE 2021.
The coronavirus pandemic caused a delay or a cancellation of several activities in the healthcare sector, leading to a 7.6% decline in healthcare public service output in FYE 2021.
Total inputs for healthcare grew by 24.2% in England in the financial year ending (FYE) 2021. This compares with a compound annual growth rate (CAGR) of 3.6% from FYE 1996 to FYE 2020.
We use appropriate deflators to obtain an estimate of input volume growth. Since FYE 2019, a specific deflator for agency staff expenditure has been produced by the Department of Health and Social Care within the NHS Cost Inflation Index.
Inputs growth in FYE 2021 was mainly driven by a 46.6% increase in real spending on healthcare goods and services. This was the biggest growth observed over the time series and it is because of the expenditure of the additional operational procurement in response to the coronavirus (COVID-19) pandemic. This includes additional personal protective equipment and goods and services associated with the operation of the NHS Test and Trace.
Labour inputs, which are mainly measured by full-time equivalent staff numbers weighted by their cost (CWAI), grew by 5.0% in FYE 2021; a faster pace than in previous years.
Capital inputs increased by 1.5% in FYE 2021. The growth of capital over the series has been quite volatile and the average growth of the last five years was equal to 0.4%.

Hospital and community output services (HCHS), the largest component of public service healthcare output, fell by 19.9% in the financial year ending (FYE) 2021. This was the first fall recorded in our time series, following small growth (0.2%) in FYE 2020. The slowdown in growth between FYE 2019 and FYE 2020 reflected a decline in follow-up outpatient attendance and slower growth in other HCHS activities (including hospital outpatient first attendances). However, the decrease in FYE 2021 output relative to FYE 2020 was driven by delayed or cancelled hospital services because of the coronavirus (COVID-19) pandemic.
Publicly funded healthcare output from non-NHS providers, which is the second biggest component based on the expenditure shares, grew by 19.1% in FYE 2021. This may be partly because of increased purchases of care capacity from the independent sector, but may also be related to the difference in methodology from HCHS, as this is measured indirectly.
The smallest two components of output (community prescribing, and primary care services) showed different trends. Community prescribing grew by 2.6% in FYE 2021, although this was still below its average annual growth rate of 6.7% since FYE 1996. However, primary care services output fell by 27.5% in FYE 2021. There were several contributing factors to this, including the provision of dental and ophthalmic services being affected by lockdowns. In general practice, there was a considerable fall in the total number of consultations in FYE 2021 and a shift in the mode of consultation away from face-to-face appointments towards phone consultations.
Combining these four healthcare components, non-quality adjusted healthcare output fell by 14.3% in FYE 2021. The introduction of NHS Test and Trace and vaccination services in FYE 2021 slowed the overall fall in volumes of existing healthcare services.
After these new services are accounted for, non-quality adjusted healthcare output fell by 7.9% in England in FYE 2021.

Quality adjustment added only a small amount to healthcare output growth (0.3%) in the financial year ending (FYE) 2021. This was mainly driven by post-operative mortality, in combination with the treatment of a younger cohort of patients in FYE 2021 compared with FYE 2020. The quality adjustment may be an overestimate of quality improvement as these data use the 2018 to 2020 life tables for FYE 2021, and our average life expectancy statistics for 2020 show a fall in life expectancy because of the coronavirus (COVID-19) pandemic.
After adjusting for quality, healthcare output declined by 7.6% in FYE 2021, which is the highest fall recorded in our time series (which began in FYE 1996).
Back to table of contents
Public service healthcare productivity is estimated by comparing growth in the total quantity of healthcare output provided (adjusted for quality where possible) with growth in the total quantity of inputs used, using inflation-adjusted volume measures. If output growth exceeds input growth, productivity increases, meaning that more output is being produced for each unit of input. Conversely, if input growth exceeds output growth, then productivity will fall.
Overall public service healthcare productivity fell by an estimated 25.6% in England in the financial year ending (FYE) 2021, the largest annual fall since our time series began in FYE 1996. This large decline in productivity continues a negative trend set in recent years, with public service healthcare productivity decreasing by 0.6% in FYE 2019 and by 1.8% in FYE 2020.
Non-quality adjusted healthcare productivity decreased by a slightly larger 25.9% in FYE 2021.
The fall in healthcare non-quality-adjusted productivity in FYE 2021 was because of inputs growth of 24.2% and a fall in non-quality-adjusted output by 7.9%
Despite inputs having always recorded positive growth, the increase in FYE 2021 is the highest recorded since the beginning of the series in FYE 1996. This reflects the extra resources provided to the healthcare system to deal with the coronavirus (COVID-19) pandemic, as discussed in the previous sections.
By contrast, non-quality adjusted output declined for the first time since the beginning of the series. The large differences between the growth in inputs and output is to be expected and has also been observed in other reports on healthcare productivity such as Productivity of the English National Health Service: Update 2021 to 2022 (PDF, 4.0MB). The pandemic led the healthcare sector to face extreme challenges and widespread postponement of elective activity.

Public service productivity estimates: healthcare, England
Dataset | Released 29 March 2023
Public service healthcare growth rates and indices for inputs, quality and non-quality adjusted output and productivity, totals and components. England, financial years ending 1996 to 2021.
Inputs are resources used to produce healthcare services. Inputs are different from expenditure and instead are expressed in volume terms. This means that an increase in staff pay will not increase inputs, but an increase in staff numbers will. Inputs can be measured directly, such as by cost-weighted staff numbers or indirectly, using appropriately deflated expenditure.
Public service healthcare productivity
Productivity is a measure of the amount of service provided (which can be either quality-adjusted or non-quality-adjusted output) for the quantity of inputs used. "Public service" relates to the fact that all healthcare services paid by the public sector are included in this measure.
In line with the recommendations of the Atkinson Review (PDF, 1.05MB), a quality adjustment is applied to the estimate of healthcare quantity output to control for the success of the service in meeting selected outcomes. For more information, see our report, Quality adjustment of public service health output: current method (PDF 153KB).
The quantity of output is the amount of healthcare services provided and is mostly measured using the number of healthcare activities performed, weighted by the cost of each activity.
Weighting refers to the relative importance of changes in individual inputs or output components to changes in the overall inputs or output index. The weight assigned is usually based on cost and so an increase of one hip replacement will have a greater effect on output growth than one outpatient consultation.Back to table of contents
Quality and methodology
Each component of productivity used in this article are outlined below.
goods and services inputs for FYE 2021 include, alongside the procurement of typical goods and services, measures for additional operational procurement in response to the coronavirus (COVID-19) pandemic, such as additional personal protective equipment, and goods and services associated with the operation of NHS Test and Trace
similarly, higher expenditure has seen capital inputs in FYE 2021 reflect the response to the pandemic
labour inputs consider full-time equivalent staff numbers, including NHS bank staff; agency staff are included in goods and services as they are not employees of the health service
labour inputs estimates do not explicitly measure overtime; while changes in the number of staff between FYE 2020 and FYE 2021 are considered in our estimates, any changes to average hours worked are not reflected in this publication
for output we have included, alongside the measures used in the previous years, the NHS Test and Trace and the COVID-19 vaccination, applying the same methods established for the UK national accounts; these were new health services established to manage and mitigate the impact of COVID-19, and represent a sizeable contribution to public service healthcare output in FYE 2021
we have used alternative data sources to estimate output growth for some hospital and community health services where this was not possible using our regular data sources, as we did with FYE 2020; more information can be found in our Improved methods for total public service productivity: total, UK, 2019 methodology
as in previous estimates, a quality adjustment (PDF, 152KB) is applied to the quantity output index where a positive (negative) quality adjustment indicates that the quality of healthcare services provided has improved (diminished), as defined by the selection of indicators used in the quality adjustment
however, for FYE 2021, patient experience and the aggregate data on clinical measures recorded on General Practitioner (GP) practice computers (based on the quality and outcome framework) were excluded since these data are not available
our estimates used the 2018 to 2020 life tables for FYE 2021, as the life tables from the period 2019 to 2021 were not yet released; as life expectancy in England is likely to have been lower in FYE 2021 than in previous years, our quality adjustment will likely be revised when updated life tables become available
More quality and methodology information on strengths, limitations, appropriate uses, and how the data were created is available in our Public service productivity: total, UK QMI (Quality and Methodology Information). The last methodological changes are explained in our Improved methods for total public service productivity: total, UK, 2019.
