NHS pay contracts introduced since 2003 have increased costs without driving productivity improvements, a National Audit Office study finds.
The following is a summary of the Management of NHS Hospital Productivity report:
1. In 2000, the Department of Health published the NHS Plan, a ten-year vision for reforming the NHS. The Plan argued that the NHS was failing to deliver because it had been underfunded, and set out to substantially increase funding in order to meet public expectations for: more, better paid staff using new ways of working; reduced waiting times; high quality care centred on patients; and improvements in local healthcare buildings.
2. NHS productivity is the measure that describes the relationship between inputs (such as staff and clinical supplies) and outputs (healthcare activity adjusted for quality). In the NHS the term ‘productivity’ is widely used but often confused with other terms like economy, efficiency and value for money. Between 2000-01 and 2010-11, NHS expenditure will have increased by 70% to £102bn from £60bn. The DoH explained that much of the additional funding was intended to be used to meet the key public expectations and would not initially be matched by a commensurate increase in outputs.
3. As over 40% of NHS expenditure is accounted for by acute NHS and foundation hospital trusts, improving hospital performance is central to achieving the expectations in the NHS Plan. The DoH expected to improve the quality and efficiency of hospital care through: national performance targets to reduce waiting times and improve patient outcomes; national pay contracts involving above inflation pay increases designed, in part, to deliver productivity improvements of between 1.1 and 1.5% a year; and the commissioning of hospital services through a national tariff system called Payment by Results.
4. In November 2009, the NHS chief executive announced that, in response to the economic downturn and increasing demand for healthcare, the NHS would need to deliver between £15 and £20bn of efficiency savings per year by 2013‑14 to be reinvested in health services. Around 40% of these savings are expected to come from driving efficiency in hospitals. To support NHS organisations to improve quality of care while making these savings, the NHS chief executive also launched the national Quality, Innovation, Productivity and Prevention (QIPP) challenge.
5. The most authoritative national measure shows a decline in hospital productivity. Figures produced by the Office for National Statistics estimate that, since 2000, total UK NHS productivity decreased by an average of 0.2% per year; however, productivity in hospitals fell by around 1.4% per year. Over the last ten years, in line with the NHS Plan, significantly more money has been spent in hospitals. This increased funding has paid for more, better paid staff, and extra goods and services. Hospital activity - adjusted to reflect improvements in the quality of care - has not risen at the same rate as these additional resources, indicating that productivity has declined.
6. The DoH has focused on delivering the government’s ambition for improved performance within an agreed budget. The increased money going into NHS hospitals has helped deliver more, better paid staff, reduced waiting times, higher quality care and improved hospital facilities. Until the end of 2009, the DoH has focused on delivering national priorities - through a combination of targets, performance management, incentives and guidance - within a fixed budget. This has resulted in improvements in, for example: inpatient median waiting times and outpatient waiting times. The DoH argues that it has not performance managed measures of productivity directly. It has focused on costing expenditure pressures and performance targets, and requiring the NHS to deliver these within an agreed budget.
7. NHS pay contracts implemented nationally since 2003 have increased hospital costs and are not always used effectively to drive productivity. Since we reported on the consultant contract and Agenda for Change, we have not been able to identify the widespread cultural shift in hospitals that we suggested was needed if the contracts were to be used to optimise productivity.
The DoH intended, for example, that consultant job planning would give hospital managers the opportunity to align consultant activity with hospital objectives; however, few hospitals have used job planning or staff appraisal systems to demonstrably improve productivity. Data show that there have been improvements in the trends for measures of labour productivity since the contracts were introduced, and the DoH believes there is a plausible link between these improvements and the introduction of the contracts.
8. The process of setting prices under the Payment by Results system has promoted some efficient practice. Recent evidence suggests that national tariffs have driven reductions in length of stay and an increasing proportion of operations undertaken as day surgeries. However, the DoH’s own hospital-level efficiency index shows substantial variation, and the tariff adjustment to account for assumed efficiency improvements is offset by uplifts to account for inflationary cost pressures, such as those resulting from the national pay contracts.
There have been delays in rolling out the national tariff to all hospital activity and the quality of information used to pay hospitals is variable. The original intention was that by 2008 all commissioning would use national tariffs; however, in 2010 around 40% of hospitals’ income is not covered by Payment by Results.
9. Hospitals have not focused sufficiently on driving productivity. The hospital managers we spoke to say they have primarily concentrated on meeting national performance targets whilst maintaining financial balance, and not specifically on optimising productivity. The national focus on quality of care has meant that clinical staff have not been performance-managed with regard to the cost or efficiency of their activities.
We found that hospital managers do not always bring performance and financial data together in a way that enables them to fully understand the relationship between the money they spend and the care they provide. There are substantial variations in hospital costs and activity, but not all hospitals use this information effectively to identify efficiency savings.
The DoH is aware of the variations in hospital costs and that they indicate potential efficiencies, with reducing variation one of the sources of savings to meet the QIPP challenge. However, we found that these variations have not been systematically interrogated by senior hospital managers or local commissioners; as a result there is limited consideration of the extent to which a hospital is delivering value for money in comparison to its peers.
The NHS Institute has estimated that the scale of productivity opportunity in hospitals through the reduction of variations in some key hospital activities is around £4.6bn. Our analysis indicates that if all hospitals performed at the level of the top 25% in respect of staff costs, use of estate, control of emergency admissions and bed management, the NHS could save around £1.6bn a year.
10. Year-on-year increases in activity have enabled hospitals to increase their income rather than drive efficiencies and local savings. Increased activity coupled with improved counting and coding of activity paid at the national tariff may have helped many hospitals to maintain financial balance. There are unexplained variations across England in the money spent by hospitals to provide the same treatments, and hospitals we visited did not understand why their costs were higher or lower than the average.
Conclusion
There are challenges to overcome if the NHS is to deliver £15 to £20bn of efficiency savings.
Some hospitals do not effectively control staff costs. Some hospitals have been slow to adopt tighter controls either over managing staff vacancies and the use of temporary and agency staff or in adopting more efficient approaches to managing staff rotas. Some managers also reported that they felt unable to effectively use the provisions within the contract to control some costs, such as recurring clinical excellence awards.
Given the unprecedented scale, there are risks to the delivery of the 2009‑launched Quality Innovation Productivity and Prevention challenge and the expected efficiency savings required by March 2014. There is a risk that SHAs and PCT, which are responsible for driving the delivery of the efficiency savings, will be distracted by their planned closure by March 2013.
The past decade has seen consistent, significant increases in hospital funding. This was designed, in part, to deliver more productive behaviour. However, hospital productivity has fallen. Whilst hospitals have used their increased resources to deliver many of the national priorities, hospitals need to provide more leadership, management and clinical engagement to optimise the use of additional resources and deliver value for money.
Any future national pay contracts should set out the expected productivity gains and efficiency savings that organisations should be obtaining, clearly linking these to the aspects of the contract that are intended to be used to realise the improvements.
Major national initiatives should include a realistic assessment of the costs and benefits, with progress against these expectations evaluated.
