Howard Fillit recognizes his mentors in geriatric medicine, particularly Robert Butler and Leslie Libow, for their inspiration and guidance. He is also grateful to Leonard and Ronald Lauder for their support and commitment to improving the quality of life for older people by conquering Alzheimer disease. He particularly wants to thank Aspasia Moundros for her constant, effective, and kind assistance in our work together.

Kenneth Rockwood is grateful to his many mentors in geriatric medicine: Duncan Robertson, John Brocklehurst, Peter McCracken, John Gray, Roy Fox, David Hogan, and Colin Powell, and to his colleagues, students, and patients who have taught him so much.

John Young has been privileged to work alongside inspiring clinicians: Graham Mulley and Alec Brownjohn (Leeds); and John Tucker, Maj Pushpangadan, and Alex Brown (Bradford). He thanks them all, and many others. And also his wife, Ghislaine, for her constant and kindhearted encouragement.

SECTION A Introduction to Gerontology

1 Introduction: Aging, Frailty, and Geriatric Medicine

The eighth edition of our text is the first since the death of John Brocklehurst, whose name it rightly bears, as its originator and longtime editor. In his Guardian obituary (http://www.the guardian.com/science/2013/jul/17/john-brocklehurst), Ray Tallis (himself a former editor of Brocklehurst, in its third to sixth editions) honored John as “the leading geriatrician of his generation,” and a man who “brought scientific gerontology to bear on our understanding of the diseases of old age.” With other early leaders, he organized training programs that helped define the specialty and guide geriatric medicine in its critical adolescent years. Those physicians laid the foundation that allowed geriatric medicine to consist of approaches and procedures that were well enough defined to be tested. This proved fortunate, because medicine was entering the evidence age, which soon demonstrated the merit of the approach. They had a view of geriatric medicine as more than “internal medicine with social work consult.” Even so, understanding just the claim of geriatric medicine continues to evolve. In the seventh edition, and continued here in the eighth, we press ahead with the view of geriatric medicine as the care of frail older adults.1 Anyone who knows the frailty literature will recognize that this is not entirely a settled claim. Still, several points are inarguable.

First, frailty refers to a state of increased risk compared with others of the same age. This same age comparison is necessary. The risk of adverse health outcomes increases with age, so without this, everyone past their fifth decade, when the increase in risk becomes noticeable, would be seen as frail.

Second, frailty is related to age. This is one point that all frailty measures have in common.2 Frailty becomes more common with age; the absolute variability in risk increases, even as relative variability declines after menopause.3 Both trends indicate systems that are moving closer to failure. The first (increase in absolute variability) shows that more people are at an increased risk; the second, a decline in relative variability, captured by a reduction in the coefficient of variation, is compatible with a decline in the response repertoire. Older adults have less to fight back with. In other words, their repair processes are less efficient, which is evidenced, among other things, in prolonged recovery times.4

Third, although the use of dichotomous cut points can obscure the extent of agreement, it is clear that the phenotype definition4 and the deficit accumulation definition5 bear much in common, as do most current operational definitions, because these typically depend on either or both approaches.2,6-12 Each identifies people who are at increased risk. For example, when people have none of the five phenotype characteristics, they have fewer deficits than when one is present.7 Likewise, people with all five phenotypic features present (e.g., weight loss, reduced higher order activities such as gardening and heavy housework, feeling exhausted, reduced grip strength, slower walking speed) have the highest

number of deficits overall.7 As ever, theses can be nuanced. Given that risk cannot exceed 1, and given that at some age, it becomes indistinguishable from 1, there must be an age at which everyone is frail. These details, like so much else, require elaboration. In consequence, there is no merit in abandoning the value of understanding frailty, even if there is disagreement about its precise operational definition.

The reason that frailty is so central to geriatric medicine is compelling. The challenge of aging to medical care lies in the complexity of frailty. As people age, it is not just that any given illness becomes more common—all illnesses become more common. Age-related change, whether it crosses a disease threshold or not, follows, on average, a trajectory of decline. Managing single illnesses is tricky enough, but the complexity imposed by frailty—managing illness in the presence of multiple interacting medical and social problems that each become more common with age—requires a specialized body of knowledge and skills. This is what constitutes geriatric medicine.

With this focus on frailty in mind, we have continued to revise and evolve the textbook. The current eighth edition includes new entries on gerontechnology, homelessness, emergency and prehospital care, HIV and aging, intensive treatment of older adult patients, telemedicine, and the built environment. We have also added a chapter on frailty, written by two authors with much experience in regard to the various ways to define frailty. Obtaining a nonpartisan view is important because all chapter authors have been encouraged to revise their chapters, not just in relation to developments in their area, but also to ensure a discussion on how it is affected by frailty. For our part, we have aimed to advocate for both types of changes, which often have resulted in mutually beneficial exchanges. This reflects how the field is evolving. It also is a pragmatic challenge for textbooks in the Internet era. The goal is less to be a compendium of all the latest information than to be an account of what is usefully known. We see the role of this text as providing context and some sense of the evolution of an area. This approach can provide value in ways that merely recitation of what is up to date at the moment might not always achieve. This has long been a goal of Brocklehurst, and one that we are keen to continue.

In the eighth edition, we recognize the stellar contributions of Professor Kenneth Woodhouse, who joined us in the seventh edition, as we began the more explicit shift in emphasis toward frailty. Now we are delighted to welcome Professor John Young. He has conducted much of the useful UK research on clinical geriatric medicine for the last decade, securing our discipline a solid evidence base, and pointing out where we need to build further. This direction has benefitted enormously from his long history of clinical practice in geriatric medicine. Those skill sets are now brought to bear in the National Health Service for

2 The Epidemiology of Aging

Age is not measured by years. Nature does not equally distribute energy. Some people are born old and tired while others are going strong at seventy.

INTRODUCTION

According to Wikipedia, epidemiology is defined as “the science that studies the patterns, causes, and effects of health and disease conditions in defined populations.” Epidemiology was first concerned with epidemics of infectious diseases when these were the main cause of death. However, with what demographers termed the epidemiologic transition, when the main cause of death in most populations worldwide shifted from infectious to noninfectious disease, epidemiologists moved their attention to chronic diseases, as well as to aging, which is more a characteristic of the population as life expectancy increases.

The body of knowledge of the epidemiology of aging has evolved into concentrating on three main areas: the causes and consequences of the aging of populations, the natural history of diseases of old age, and the evaluation of services set up to assist older people. This chapter will concentrate on the first of these, with a discussion of the burden of disease in old age generally, rather than for specific disease, and the implications of this for health and care services; the other two sections will be covered more fully elsewhere in the text.

The Causes and Consequences of Population Aging

The early twenty-first century is unique in a number of aspects, but in relation to the people of the world, it is most remarkable as a time when humans live appreciably longer than ever before. Perhaps even more remarkably this rate of prolongation of average life expectancy shows little signs of abating. This extraordinary piece of good luck for those of us who live at this time is tempered a little by the knowledge that life insurers and those calculating pensions have been betting our money on our not living so long, so we may be poorer than we had hoped.

Longevity

The constancy of the increase in human life expectancy over the past decades, at around 2 years every decade, or 4 to 5 hours per day, has surprised scientists and the population generally. Before 1950, most of the gain in life expectancy was due to reductions in death rates at younger ages. Demographers were confidently predicting that once these gains, made by reducing mortality in early and middle life, had reached completion, growth in longevity would stop and we would see the fixed reality of the aging process. However, in the second half of the twentieth century, improvements in survival after the age of 65 years caused the increase in the length of people’s lives and, indeed, mortality rates even in very old age have fallen. Experts who have repeatedly asserted that life expectancy is close to an ultimate ceiling have repeatedly been proven wrong, and most forecasts of the maximum possible life expectancy in recent years have been broken within 5 years of the forecast.1,2

The results of these remarkable increases in life expectancy have been the so-called graying of our populations. In 2010, around 8% of the world’s population was aged 65 years or over,

and this is expected to double, to 16%, by 2050—but these figures hide two facts. First, that the older population itself is aging; the fastest growing section of most populations worldwide is those aged 85 years and older, the very old, who are forecast to number 377 million worldwide by 2050. There has also been an exponential increase in the number of centenarians in countries such as Japan, France, and the United Kingdom (UK), as well as the emergence of another section of the population, supercentenarians, those aged 110 years and over. The modal age at death, a measure of average life span, has been increasing steadily in the UK (Figure 2-1), reaching 85 years for men and 89 years for women in 2010, and therefore already surpassing the upper limit for life span of 85 years to be reached by 2045 (theorized by Fries3).

Second, not all countries are aging at the same pace. It took France around 110 years for its older population (aged 65+ years) to rise from 7% of the population to 14%. Sweden took 80 years and the UK 50 years, but Brazil and South Korea are forecast to reach this level of demographic aging in less than 20 years. Thus, the political and societal accommodation to demographic aging will have to be made much more rapidly in developing countries.

The ratio of the dependent population to the economically active or working population is termed the dependency ratio. This has been commonly defined as the ratio of the population aged 65 years and over to those aged 15 to 64 years. For the European Union (EU) as a whole, the dependency ratio is 28.2 and it is projected to rise to 49.2 by 2050. However, the aging of the population and low fertility rates means that for some European countries, the dependency ratio is much higher. For example, the ratio in Spain is 27.2 but by 2050 will reach 60.5 (Table 2-1). Nevertheless, this ratio may become less useful in the future as the retirement age is increased, and indeed many people over the age of 65 remain in the workforce, whereas there are those under the age of 65 who are not part of the working population— children, students, housewives, husbands, and the unemployed. Being not formally employed does not mean that they are not contributing to the economy. Grandparents contribute hugely in terms of child care for working and retired people, especially women, and are one of the biggest groups caring for older disabled relatives, most often a spouse. Thus, the dependency ratio does not reflect the need for care, the more usual use of the term dependency. For this, the oldest old support ratio, the ratio of people aged 50 to 74 years to those aged 85 years and older, has been proposed.4

Because of the youthfulness of immigrants, immigration is often seen as a solution to the “problem” of population aging in countries with low fertility. Presently, the lack of people to take jobs in developed countries, for example in the care sector, draws young people from developing countries, lowering the average age of the population. There are, however, cohorts from the West Indies and Southeast Asia, predominantly India and Pakistan, who came to the UK in the 1960s and 1970s and who have now aged into the older population. Although their numbers are small, they will increase, and they are known to have higher risks of

cardiovascular disease, stroke, and diabetes,5 although little is known about their rates of cognitive impairment or disability.

Why Do We Age?

There now appears to be a reasonably clear consensus that the aging process is caused by an accumulation of molecular damage over time. The rate of aging in an individual is therefore a complex interaction among damage, maintenance, and repair. These interactions are, of course, influenced by genetic and environmental factors. It has been said that whoever created humans, whether nature or a creator, did a poor job but, being aware of it, put in a lot of backup systems. On the other hand, it may be a universal law that hyperefficiency is less effective in the long run than flexibility. This may be a useful lesson beyond the realms of longevity in a world seemingly more concerned about efficiency than effectiveness.

It is assumed that genetic changes are unlikely to alter appreciably, under evolutionary pressure, over the short period, during which longevity has dramatically increased. The reason for the increasing longevity is therefore said to be caused by the interplay of advances in income, nutrition, education, sanitation, and medicine, with the mix varying over age, period, cohort, place, and disease. It seems likely, then, that these changes are largely a result of a wide range of environmental factors.

The birth cohorts of the early 1900s experienced huge changes in socioeconomic conditions, hygiene, lifestyle, and medical care, leading to dramatic falls in infant mortality and infectious and respiratory disease rates. The main effects were improvements in housing, sanitation, and nutrition; the control of infectious diseases and maternal mortality; and the advent of antibiotics and vaccination.6 In later years, it has been the survival of older people that has led to the extension of life expectancy, due predominantly to reductions in cardiovascular and stroke mortality and increasing survival for many cancers. Life expectancy at age 65 years in the UK has risen by 5.2 years for men and 3.8 years for women since 1981, equating to an increase of 40% for men and 20% for women.

HEALTHY AGING

The prevalence of the major chronic diseases—coronary heart disease (CHD), stroke, and dementia—which have grown in importance over the century, increases with age. This is particularly the case for dementia, where the prevalence approximately doubles for every 5-year increase in age.7 Moreover, very old age is characterized by multiple, rather than single, diseases. In the Newcastle 85+ Study, none of the men and women aged 85 years were free of disease (Figure 2-2); on average, men and women had four and five diseases respectively, whereas around 30% had six or more diseases.8 This accumulation of disease has implications for the delivery of health care because, at least in the UK, secondary care is organized predominantly around single diseases. However, the high level of multimorbidity is also a strong contributor to frailty, reflecting the accumulation of deficits inherent in the Frailty Index.9
