Statistical bulletin: Avoidable Mortality in England and Wales, 2011

Released: 22 May 2013 Download PDF

Key findings

  • In 2011, deaths from potentially avoidable causes accounted for approximately 24% of all deaths registered in England and Wales.
  • The leading cause of avoidable deaths was ischaemic heart disease in males and lung cancer in females. In 2011, both conditions represented 22% and 15% of all avoidable male and female deaths respectively in England and Wales.
  • In England and Wales, avoidable mortality rates fell by 28% from 243.2 to 175.8 per 100,000 population between 2001 and 2011.
  • Avoidable mortality rates were significantly higher in Wales than in England throughout the period 2001–11.
  • Avoidable mortality rates varied across the regions of England and tended to be highest in the North of England and lowest in the South and East of England over the period 2001–11.

Summary

This bulletin presents mortality figures for causes of death that are considered avoidable in the presence of timely and effective healthcare or public health interventions (avoidable mortality). Figures are presented for England and Wales and the regions of England for the period 2001–2011. Trends in mortality by causes considered preventable (preventable mortality) or amenable to healthcare (amenable mortality), which are subsets of total avoidable mortality are also presented. Definitions of avoidable, preventable and amenable mortality are displayed below. 

Mid-year population estimates for England and Wales from 2002 to 2010 have been revised in light of the 2011 Census populations. Previously published data on avoidable mortality relating to this period have therefore been revised in this bulletin.

Definition of Amenable, Preventable and Avoidable mortality 

Amenable mortality: A death is amenable (treatable) if, in the light of medical knowledge and technology at the time of death, all or most deaths from that cause (subject to age limits if appropriate) could avoided through good quality healthcare.

Preventable mortality: A death is preventable if, in the light of understanding of the determinants of health at time of death, all or most deaths from that cause (subject to age limits if appropriate) could be avoided by public health interventions in the broadest sense.

Avoidable mortality: Avoidable deaths are all those defined as preventable, amenable or both, where each death is counted only once. Where a cause of death is both preventable and amenable, all deaths from that cause are counted in both categories when they are presented separately. 

Background

It is widely accepted that the contribution of healthcare to improvements in population health ought to be quantified. An indicator widely used in measuring this contribution is avoidable mortality, which is based on the concept that premature deaths from certain conditions should not occur in the presence of timely and effective healthcare. Although research on avoidable mortality has gone on for the last three decades, there is little consensus among researchers about how to define it.

The concept of avoidable mortality was first introduced by Rutstein et al. in the 1970s. They listed conditions where a single case of untimely death would justify asking the question, ‘Why did it happen?’ They also selected conditions in which critical increases in rates of untimely death could serve as an index of the quality of healthcare (Rutstein et al., 1976). These causes of avoidable deaths were intended to highlight areas of healthcare quality that could benefit from improvements.

Rutstein also noted that the list of conditions considered to be avoidable would need to be updated in light of improvements in medical knowledge and practice, as well as social and environmental changes. As a result, their original lists were revised in 1980 to take these and the move to the Ninth Revision of the International Classification of Diseases (ICD-9) into account.

In England and Wales, Charlton et al., (1983) were the first to examine avoidable mortality. They investigated the geographic variations in mortality between 1974 and 1978 using 14 amenable causes of death selected from Rutstein’s list. As with several researchers after them, they excluded conditions such as lung cancer, whose avoidance was considered to be outside the scope of medical care. They found that even after adjusting for social factors, substantial variations in avoidable deaths remained and they urged future studies to examine this further in relation to health-service inputs.

More recently, the concept of avoidable mortality has been expanded to differentiate between conditions amenable to healthcare (treatable) and those preventable through wider public health policies. Some of the more recent lists of avoidable causes of death include those produced by Nolte and McKee (2004) and Page, Tobias and Glover (2006). These cause lists were adopted as the basis for the definition of avoidable mortality used by ONS. They have been amended and updated to make them more relevant to the United Kingdom and to take account of more recent developments in health public policy.

Limitations

One of the main difficulties in producing an indicator of avoidable mortality is the selection of the causes of death for inclusion. While a particular condition can be considered to be avoidable, this does not mean that every death from that condition could be prevented. This is because factors such as the age of the patient, the extent of disease progression at diagnosis or the existence of other medical conditions are not taken into account when compiling a list of causes.

Several studies have shown that deaths from causes amenable to healthcare are declining at a much faster rate than those from non-amenable causes and that this decline has coincided with the introduction of specific improvements in healthcare. However, some studies have found only a weak association, if any, between the levels of healthcare supply and geographical variations in amenable mortality. According to Nolte and McKee (2004), these studies are largely focused on quantitative measures such as healthcare expenditure and the number of healthcare professionals, not necessarily measures of the quality of healthcare systems. They therefore argued that the lack of demonstrable association is in fact not entirely surprising. Furthermore, there is likely to be a substantial time lag between change in resources, the introduction of a healthcare innovation or public health policy and a corresponding reduction in mortality. As a result, improvements in the healthcare system may not necessarily be evident from mortality figures in the short or medium term.

In a review of published work on amenable mortality, Mackenbach et al., (1990) noted that geographical variations were strongly linked to socioeconomic factors which may in turn reflect the differences in timely access to healthcare. Geographical variations may also simply be a result of random variations in disease incidence. For example, if there was a sudden increase in the incidence of a particular condition, and consequently an increase in the mortality rate for this condition, this might be mistakenly interpreted as a decrease in the quality of healthcare.

It is noteworthy that avoidable mortality was not intended to serve as a definitive source of evidence of differences in effectiveness of healthcare systems; rather it was designed to highlight areas of potential weaknesses in healthcare that could benefit from further in-depth investigation (Nolte and McKee, 2004). It is therefore anticipated that the statistics provided in this bulletin would help in assessing the quality and performance of healthcare as well as wider public health policies. However, in light of the limitations above, a degree of caution is required when interpreting the data.

Coding changes

In 2011, ONS updated the software used for cause of death coding from the International Classification of Diseases, Tenth Revision (ICD-10) version 2001.2 to version 2010. Following this, ONS carried out a bridge study to help users understand the likely impact of this change on mortality statistics for England and Wales. The main changes in the ICD-10 version 2010 are amendments to the rules used in selecting the underlying cause of death. Overall, the impact of these changes is small although some cause groups are affected more than others.

Many of the conditions affected by the changes are not included in the avoidable mortality definition used in this bulletin. In the majority of cases, where conditions are affected, deaths previously coded to one condition are now coded to another also included in the definition. Therefore, the coding change will have had little impact on the summary avoidable mortality figures for 2011 provided in this bulletin.

Methods

Following a public consultation on what the ONS definition of avoidable mortality should be, it was decided ONS would present avoidable mortality statistics using directly age-standardised rates. This measure is widely used in presenting mortality statistics and there is a standard method for carrying out the calculations. In this bulletin, figures are also presented using standardised years of life lost. This is solely in response to demand from customers and does not reflect a change to ONS’s formal measure of avoidable mortality. It should be noted that the two measures are not directly comparable (see Results section), and figures based on standardised years of life lost are presented for England and Wales only.

Age-standardised rates were calculated using the number of potentially avoidable deaths registered in each year as the numerator and the mid-year population estimate for that year as the denominator. These rates were calculated for all avoidable, preventable and amenable deaths as well as cause groups within these categories. Although age limits were set for some cause groups, rates were calculated using persons of all ages as the denominator. This method was adopted since the entire population is at risk of mortality due to causes considered to be avoidable at an aggregate level and also to allow data by cause group, amenable and preventable categories to be presented on a comparable basis.

Potential years of life lost (PYLL) is a measure of the potential number of years lost when a person dies prematurely from any cause. The basic concept underpinning PYLL is that deaths at younger ages are weighted more heavily than those at older ages. The advantage in doing this is that deaths at younger ages may be perceived to be of less importance if cause specific death rates alone were used in highlighting the burden of disease and injury since conditions such as cancer and heart disease often occur at older ages and have relatively high mortality rates.

In this bulletin, PYLL are expressed as age-standardised rates (SYLL). These rates represent the potential years of life lost if the population of England and Wales had the same population structure as the European Standard Population. SYLL rates are presented as years of life lost per 100,000 population.

PYLL is calculated as the sum of the mortality rate in each age group weighted by the potential number of years of life lost as indicated by remaining life expectancy for each age group. To calculate the SYLL, this is then standardised to the European Standard Population (ESP) as shown below.

Results - England and Wales

England and Wales

In 2001, deaths from potentially avoidable causes accounted for approximately 26% (140,820 out of 532,498) of all deaths registered in England and Wales. This proportion has since fallen, with avoidable deaths accounting for almost 24% (113,910 out of 484,367) of all deaths in 2011.

Men are more likely to die from potentially avoidable causes, with about 29% (68,839 out of 234,660) dying from avoidable conditions compared with 18% (45,071 out of 249,707) of women in 2011.

Between 2001 and 2011, the age-standardised mortality rate for potentially avoidable causes fell significantly from 243.2 deaths per 100,000 population to 175.8 per 100,000 population. The decline in rates occurred at a faster pace for men than for women over this period. While the rate for men fell by approximately 29% from 313.3 per 100,000 in 2001 to 221.2 per 100,000 population in 2011, for women the corresponding decrease was from 178.1 to 132.6 per 100,000, a 26% fall.

The mortality rates for amenable causes were lower than those from preventable causes while the decline in these rates was greater for amenable causes. Amenable mortality rate for England and Wales fell by 38% from 138.5 per 100,000 population in 2001 to 85.5 per 100,000 in 2011. Over the same period, the preventable mortality rate decreased by 26% from 196.6 to 145.0 per 100,000.

Overall, ischaemic heart disease (IHD) was the leading cause of avoidable deaths, accounting for 18% (20,244 out of 113,910) of all avoidable deaths in 2011. However, the leading cause of avoidable mortality differed by sex. For males, it was ischaemic heart disease, accounting for 22% of all avoidable male deaths. In contrast, malignant neoplasm of trachea, bronchus and lung (lung cancer) was the leading cause in females, accounting for 15% of all avoidable female deaths. The relative impact of IHD on male and female avoidable mortality rate is shown in Figure 2.

Analysis of causes of avoidable death at a broader level (cause groups) showed that cardiovascular diseases were the largest contributors to avoidable deaths between 2001 and 2006. In 2007, neoplasms became the leading cause of avoidable deaths and have remained so since. The change in ranking occurred because deaths from cardiovascular diseases were falling at a much faster pace than deaths from neoplasms. While the mortality rate for avoidable cardiovascular diseases fell by 48% from 95.5 per 100,000 population in 2001 to 49.3 per 100,000 in 2011, the rate for avoidable neoplasms fell by only 15% (73.9 to 63.1 per 100,000) in the same period. There has been no significant decrease in the mortality rate for neoplasms since 2009.

Similar to individual causes of death, the cause group responsible for most avoidable deaths differed by sex in 2011. For males cardiovascular diseases were the leading cause of avoidable deaths with a mortality rate of 70.6 per 100,000 population. Conversely, neoplasms were the main cause of avoidable female deaths (58.3 per 100,000).

The mortality rates for all cause groups examined fell significantly between 2001 and 2011. However, for the majority of groups there were considerable fluctuations within this period, characterised by relative stability and significant increases and decreases in rates. Cardiovascular diseases were the only exception to these fluctuations, with significant decreases observed in rates in every year over the period.

The trend in overall avoidable mortality was similar regardless of the indicator used, with both age-standardised rates and SYLL decreasing in each year between 2001 and 2011. For males, 6,638 potential years of life per 100,000 population were lost by those who died from conditions considered avoidable in 2001 compared with 5,291 years of life per 100,000 lost in 2011. For females, the comparable years of life lost were 4,231 per 100,000 in 2001 and 3,449 per 100,000 in 2011.

For males, all of the cause groups examined were similarly ranked regardless of the mortality indicator used but this was not the case for females. For example, though respiratory diseases were ranked higher than injuries for females using age-standardised rates (15.2 compared with 14.7 per 100,000 population), using SYLL they were ranked lower as more potential years of life were lost by those who died from injuries than from respiratory diseases (431.8 compared with 349.4 years lost per 100,000 population). This indicates that although mortality from both causes tend to increase with age, significantly higher numbers of avoidable deaths at younger ages occur from injuries compared with respiratory diseases.

Results - England

The avoidable mortality rate for all persons in England fell significantly by 28% from 240.4 per 100,000 population in 2001 to 173.5 per 100,000 in 2011. Similarly, rates for males and females fell significantly from 309.8 to 218.4 per 100,000 and 175.9 to 130.9 per 100,000 respectively over the same period.

In 2011, neoplasms and cardiovascular diseases were ranked the first and second largest contributors, respectively, to overall avoidable mortality but this was not always the case. While mortality rates and the number of deaths from cardiovascular diseases were the highest of all the groups of avoidable causes in 2001, this was no longer the case in 2007 when the rates and number of deaths were higher for neoplasms. In a recent study, Bajekal et al (2012) found that medical and surgical treatments were responsible for about half of the decline in mortality from coronary heart disease, a sub-group of cardiovascular diseases, observed in England between 2000 and 2007. A further third of this decline was attributed to changes in lifestyle and behavioural risk factors such as smoking and physical activity. However, they also noted that the benefits of improvements in blood pressure, cholesterol levels, smoking and physical activity were partly negated by increases in body mass index and diabetes.

Results - Wales

Avoidable mortality rates were significantly higher in Wales than in England throughout the period 2001–11.

The difference in rates between both countries over the period appears to be largely due to the relative contribution of cardiovascular diseases to overall avoidable mortality in Wales. Cardiovascular diseases were the only cause group with significantly higher rates in Wales than in England and the difference in rates was greatest for this group throughout the period 2001–11.

Avoidable mortality rates fell in Wales by 26% from 264.4 per 100,000 in 2001 to 196.4 per 100,000 in 2011, a smaller proportional decrease that than observed in England. Avoidable mortality rates in Wales were higher for males than for females in all years, however larger proportional reductions occurred in male mortality rates (Tables 1 and 2). In 2011, the avoidable mortality rate for males was 246.0 per 100,000 compared with 149.2 per 100,000 for females.

Prior to 2008, cardiovascular diseases were the leading cause of deaths, having the highest mortality rate of all the groups examined. Due to a relatively steeper decline in avoidable cardiovascular mortality rates in the period 2001–11, neoplasms replaced this cause group as the leading cause of avoidable mortality in 2008 and have remained the group with the highest mortality rate since. In 2011, the mortality rates for avoidable cardiovascular diseases and neoplasms were 56.7 and 65.2 per 100,000 respectively.

Results - Regions of England

Avoidable mortality rates varied across the regions of England and tended to be higher among those in the north than the south. In 2011, rates for males were highest in the North East (265.6 per 100,000 population) and lowest in the East of England (189.1 per 100,000). For females, rates were also highest in the North East (165.0 per 100,000) but lowest in the South East (114.6 per 100,000).

Avoidable mortality rates decreased in all regions between 2001 and 2011. The largest decrease was observed in London where rates fell by 35% from 324.7 to 210.8 per 100,000 for males and by 34% from 181.8 to 120.4 per 100,000 for females. The smallest change in rates over the period was in the South West for males (26%) and in Yorkshire and The Humber for females (21%).

Users and Policy context

This is the second in a series of statistical bulletins produced in response to user demand for statistics on avoidable mortality from central government, public health observatories, academia and charitable organisations working to reduce the prevalence of specific diseases and conditions deemed to be avoidable causes of death.

One of the main expected uses of these statistics is the monitoring of the quality performance of healthcare and public health policies. The Department of Health uses Potential Years of Life Lost from causes considered amenable to healthcare as an indicator in its NHS Outcomes Framework 2012/13 (Department of Health, 2011) and mortality from preventable causes as an indicator in its Public Health Outcomes Framework (Department of Health, 2012).

There has been considerable local and international interest in the development of statistics on avoidable mortality in the last two decades. In the UK, charitable organisations such as the Hepatitis C Trust, the British Lung Foundation and the British Association for the Study of Liver (BASL) are keen to see the conditions or diseases they campaign about included in the list of causes of death considered avoidable. It is anticipated that inclusion in these conditions on the cause list would draw increased attention towards them and allow comparisons of trends to be made against other conditions.

At an international level, the European Union funded project ‘Avoidable mortality in the European Union: Towards better indicators for the effectiveness of health systems’ (AMIEHS, 2011) aims to develop a list of indicators (causes of death) for which mortality rates are likely to reflect variations in the effectiveness of healthcare, as defined by primary care, hospital care and personalised health services. To date, the project has developed an ATLAS containing trends in mortality for 45 possible amenable causes. Similarly, the Office for Economic Co-operation and Development (OECD) published a working paper in 2011 titled: ‘Mortality amenable to healthcare in 31 OECD countries: estimates and methodological issues’. The study assessed the feasibility of using amenable mortality as an indicator of the performance of healthcare systems in OECD countries, concluding that the potential for this indicator for cross-country comparisons of healthcare effectiveness is very high.

 

Results on the Office for National Statistics website

Avoidable mortality figures for England and Wales combined, England, Wales and the regions of England are available from the Data in this release section.

The workbooks contain:

  • Results for England and Wales (combined and separately) – age-standardised rates per 100,000 population (with 95% confidence intervals), standardised years of life lost and the numbers of deaths for causes considered avoidable, amenable and preventable for the period 2001–11. Data are available by cause group: infections; neoplasms; drug use disorders; cardiovascular diseases; respiratory diseases; injuries; and other conditions.

  • Results for England and Wales (combined and separately) and the regions of England – age-standardised rates per 100,000 population (with 95% confidence intervals) and the numbers of deaths for causes considered avoidable, amenable and preventable for the period 2001–11. Data are for males, females and all persons.

  • Results for England and Wales (combined and separately) – underlying dataset containing the number of deaths for each avoidable mortality cause group, broken down by sex and five-year age groups.

Background notes

  1. Statistics on mortality are derived from the information provided when deaths are certified and registered. Further information about the methods and quality of these statistics can be found in the Mortality Metadata (2.7 Mb Pdf) document on the ONS website.

  2. In England and Wales deaths should be registered within five days of the death occurring. However, there are some situations which result in the registration of deaths being delayed. Deaths considered unexpected, accidental or suspicious will be referred to a coroner who may request a post mortem or carry out a full inquest to ascertain the reasons for the death. Further information on the impact of registration delays on the quality of mortality statistics can be found on the ONS website

  3. This bulletin presents age-standardised (also known as ‘directly-standardised’) rates, standardised to the European Standard Population. These make allowances for differences in the age structure of the population, over time and between sexes. The age-standardised rate for a particular cause of death is that which would have occurred if the observed age-specific rates for that cause had applied in the given standard population.

  4. Figures are for deaths registered in each calendar year while rates are based on mid-year population estimates as the denominator. Mid 2002–10 population estimates have been revised in light of the 2011 Census. Rates presented in this bulletin are therefore based on the revised population for these years and may therefore differ from those in the previous avoidable mortality bulletin. However, as at the time of writing, revised population estimates were not available for English regions. As a result, figures were only revised for England and Wales (combined and separately).

  5. Within this bulletin, a difference which is described as ‘statistically significant’ has been assessed using confidence intervals. Confidence intervals (CIs) are a measure of the statistical precision of an estimate and show the range of uncertainty around it. Calculations based on small numbers of events are often subject to random fluctuations. Significance is assigned on the basis of non-overlapping CIs. While more formalised and accurate methods of significance testing are available, the non-overlapping CI method is used because it is both simple to calculate and easily understood. As a general rule, if the confidence interval around an estimate overlaps with the interval around another, there is no significant difference between the two estimates
