Nov 2016 How much is enough: what should we be spending on the NHS? Drivers of changes in national health care spending are usually considered under four headings: Demographic pressure: a growing population means more people needing health care; and the good news that average life expectancy is increasing means that a growing proportion of the population is elderly, which in turn means higher health care spending because the need for health care is greatest among the elderly; Expectations of ever better health care: expectations that increase with income and as scientific and technical progress expands the scope of what health care can do; New technologies increasing the range of health care that is possible, but also offering opportunities to improve the productivity of health care; Relative price effects: because much health service spending is on providing care that necessarily requires face to face contact time between health care professionals and individual patients, meaning that productivity is hard to improve in those areas (an hour of care always takes an hour) while health care professionals’ wages must rise in line with those in the rest of the economy.

Approaches to modelling health care expenditure
Nov 2016 How much is enough: what should we be spending on the NHS? Approaches to modelling health care expenditure Micro-simulation models, which track hypothetical patients through life events and calculate HCE at the individual level. Such models are complex and extremely data intensive, but provide a powerful analytical tool. The authors suggest this type of modelling is particularly useful to test ‘what-if’ policy questions, as individuals can be gathered into policy relevant groups, simulated through their life-time, and analysed accordingly; Component-based models, which estimate expenditure for different components and then combine these – the different components could be financing agents, providers, goods and services, or groups of individuals (for example different age groups). Component-based models are less demanding in their data requirements than micro-simulation models, and they are also relatively simple to implement and maintain. The impact of policy changes can be assessed through manipulation of any policy parameters. Astolfi et al. speculate that these reasons explain the popularity of this type of model in the policy arena; Macro-level models, which typically analyse aggregate health expenditures through regression analysis of time-series data. The authors suggest that macro-level models are often well suited to short-term projection where trends are undisturbed. Projections within macro- level models are either based on the extrapolation of time-series data, or on projected values of key explanatory variables, therefore this type of modelling is less demanding than others in terms of data requirements and computational burden.
