Geriatric medicine and geriatricians in the UK. How they relate to acute and general internal medicine and what the future might hold?
Abstract
The Royal College of Physicians and its Future Hospitals Commission has a renewed focus on general internal medicine. But in 2015, most is in effect either acute medicine or geriatric medicine. Acute physicians and ‘organ specialists’ looking after inpatients on specialty wards or at the acute hospital ‘front door’ will need sufficient skills in geriatric medicine, rehabilitation, discharge planning and palliative care, as frailty, dementia and complex comorbidities may complicate the care of older patients with predominant speciality-defining complaints. In an era where we are urged to focus on patient-centred care, patients’ preference for continuity and ‘whole-stay’, consultants must be recognised and respected. Ideally, this will require increasing numbers of geriatricians and acute physicians, more age attuned training for all; a shift in values and status. This should be backed by adequate capacity and rapid access to social and intermediate care services outside hospital, as well as adequate multidisciplinary staff and skills within the acute hospital to ensure that older patients’ needs beyond the immediate complaints are not neglected. Meanwhile, geriatric medicine itself has diversified into specialised, community and interface roles, aligned with the integration agenda, and continues to contribute substantially to acute, general and stroke medicine. These developments are described here.
Introduction – how we got here
When the NHS was founded in 1948, around 48% of people died before 65.1 Now, that figure is around 12%, with men and women at 65 expected to live on average 18 and 20 more years, respectively.2 The ‘oldest old’ (over 85) are the fastest growing age demographic.3 By 2030, around 1 in 5 of the population will be over 65 and life expectancy at 65 is projected to be 88 for men and 91 for women.4
Medical specialities in those early post-war years tended to focus on short-lived, infectious or ‘single-organ’ diseases generally affecting people below retirement age. This has indirectly coloured the way our services, training and specialities are configured to this day.
UK geriatric medicine came to prominence in the 1940s with the pioneering work of Warren, Amulree, Howell and Exton-Smith among others, and with the founding of the British Geriatrics Society (BGS).5 Its pioneers demonstrated the value of specialised and skilled assessment of older patients both to those individuals and to hospitals. Back then, geriatricians were far from the mainstream of acute adult medicine and centred in long-stay facilities.6 We are now the largest UK internal medicine speciality with at least 1,350 consultants, with most consultants dually accredited in general internal medicine (GiM) and many also in stroke or acute medicine.7
The BGS has defined geriatric medicine thus: ‘a branch of GiM that is concerned with the clinical, preventative, remedial and social aspects of illness in old age. The challenges of frailty, complex comorbidity, different patterns of disease presentation, slower response to treatment and requirements for rehabilitation or social support require special medical skills’.8 This is explored in more detail in the Royal College of Physicians’ Consultant physicians working for patients resource on the speciality.9 A recent article in this journal10 discussed how we identify older people with frailty and related syndromes and presentations, and the key importance and evidence behind expert, holistic multidisciplinary assessment, treatment and follow up (comprehensive geriatric assessment).11 Readers are referred back to that piece and to a number of recent resources and clinical reviews on care for patients with frailty.12–14 These describe our core patient group – the one for whom we make the biggest difference – and the basis of our speciality’s skill.
Principles of good practice around care for older people have been set out in the RCP Acute care toolkit,15 the ‘Silver Book’ on urgent care for older people, written by several colleges and specialist societies,16 in major King's Fund reports17–19 and by Health Improvement Scotland20 among other bodies. A consensus has emerged about ‘what good looks like’ and how we need to change. Geriatricians, specialist acute physicians and emergency department consultants are unusual in being defined more by a group of patients, a phase of illness and a range of common presentations than by system or organ diseases. Though they may have been seen by some as ‘poor relations’ these ‘expert generalism’ specialities are crucial in making pressurised modern acute hospitals work.21,22
Given that frailty, dementia, multiple comorbidities, post-acute rehabilitation, discharge planning and end-of-life care ‘travel with’ a range of patients in adult medicine, it is increasingly important that all clinicians in adult care gain some competencies in this area and shift approaches for the older population they are now dealing with. The RCP’s Acute care toolkit,15Hospitals on the edge,23Future Hospital: caring for medical patients24 and Hospital workforce fit for the future25 all acknowledged that our current models, skills and values must change to reflect the increasingly old and complex nature of modern hospital case mix.
Future Hospital exemplar sites are focusing on the care of older people.26 Both NHS Benchmarking27 and the King’s Fund19 have outlined major variation in practice, activity and outcomes around hospital care of older people. Initiatives such as the Future Hospital and the Acute Frailty Clinical Network,28 and work of NHS Emergency Care Intensive Support Team29 focusing on dissemination and adoption of best practice, all aim to embed these approaches. UK consultants in several major ‘organ specialities’ are often lengthily trained, dually accredited general physicians.7,25 However, the number of consultants described as purely ‘general (internal) medicine’ has diminished.30,31
Against this background, the evidence base for specialist care and interventions for specific conditions has grown to the extent that it’s much harder for a jobbing generalist to do as well as an expert specialist for specific single conditions. In England, waiting time targets, financial incentives and an understandable demand for separate ‘speciality rotas’ alongside acute general medicine have put additional pressure on GiM-accredited specialists to focus on their ‘ology’. This can leave them pulled in different directions, trying to satisfy needs around acute inpatient care and other work, and sometimes feeling they’d be better leaving, stopping or reducing their commitment to acute or inpatient GiM. This arguably runs against the RCP current push to have more trainees doing more GiM during training.24,25
The principle focus of this article is on the current and future role of geriatricians and geriatrics, with some reference to our relationships with acute and general medicine. We have written it from a geriatrician’s perspective, though are GiM trained and many contribute substantially to all-age GiM and acute medicine.
What roles can geriatricians play?
The range of clinical and service leadership activities played by geriatricians has expanded along with our numbers, increasing demand, changing patient demographic and a growing evidence base for our craft. Further expansion may have been a consequence of some other disciplines’ flight from old fashioned general medicine and the acute take and the contraction of standalone ‘general medicine’ posts. We contribute variously to the following; however, the list is not exhaustive, with some geriatricians contributing to specialist areas such as bone fragility or continence services for instance.
Contribution to GiM and the ‘unselected take’
1. Geriatricians often provide a disproportionate contribution to the acute unselected GiM take, regardless of patient age; in a few (usually larger) hospitals there are separate acute medicine and acute geriatric service. Geriatrics contributes 12% of acute general medicine workforce in the UK.7,30 Geriatricians are well trained in GiM. Many enjoy and value it though as with other specialities there is a range of interest levels. However, looking after younger non-frail patients could potentially distract from our core mission of caring for older people with frailty and complex needs.
2. A number of geriatricians work as acute physicians31 and some with ‘triple accreditation’. In these roles they can add value to the hospital ‘front door’ and help improve geriatric medicine practice and protocols across all acute medical unit services.
3. Leadership and service delivery in stroke medicine: Much of the improvement drive, service development and evidence base in stroke medicine, including stroke units, supported discharge and acute stroke services, has been driven by geriatricians.32–34 We provide around 60% of all stroke services (for young and old) and approximately 60% of stroke consultants come from a geriatric medicine background. These clinicians have actively chosen stroke medicine and many continue in general medicine or geriatrics alongside this. However, busy stroke work inevitably limits their capacity for these other roles. Many stroke patients are older people with complex needs, making a geriatric medicine background useful.
Acute assessment and intervention for older people with frailty
4. Acute geriatrics or acute frailty medicine – working in the emergency department (ED)35,36, medical acute medical unit37,38 or co-located in acute frailty units.10,15,28,39 In these roles we identify older people with frailty and initiate early comprehensive geriatric assessment. We work closely with multidisciplinary teams including nurses, therapists, social workers discharge coordinators and voluntary organisations to facilitate early discharge home or to community services. These models sometimes access ‘discharge to assess’ teams, community ‘in reach’ or ‘pull’ teams to expedite discharge and ongoing support as soon as patients are sufficiently ‘medically fit’ (not the same as ‘back to baseline’). In some units, ‘interface geriatricians’ work across the acute/community care divide.40,41
5. Rapid-access chair-based access clinics for older people – the geriatric medicine equivalent of ambulatory care clinics in acute medicine (with some overlaps). Such clinics with same or next-day access to specialist ‘one stop’ assessment have been used successfully to divert patients away from busy and distressing ED and can be used at scale.42,43
6. Acute inpatient care beyond the front door. The evidence base for comprehensive geriatric assessment is strongest for speciality ward based care.11 Ward moves add to length of stay and worsen continuity.44 Outlying patients even under the same team tend to stay longer.45 Despite some limited successes with specialist older peoples liaison teams visiting ‘outlying’ wards for advice on complex older patients,46,47 a principle of ‘discharge to assess’ (back home close to the front door) or ‘decide to admit’ to the first ward first time is a good one.19,48 A relentless focus on discharge planning, minimising internal and external delays, with geriatricians consistently involved has been shown to reduce bed occupancy, with secondary improvements to other outcomes.17,29,49–53
Managing frailty as a long-term conditions
7. General and specialist outpatient work. Outside of community, rapid-access ambulatory clinics and stroke/transient ischaemic attack clinic geriatricians do still deliver outpatient work, though not at the scale of many organ-specialist colleagues.9 Indeed, it may not always be in the best interests of older people with frailty, dementia or disability to be bringing them for repeated outpatient follow-up. Geriatric medicine has led the way in developing the evidence-base and service models for falls clinics which assess patients and refer on for further intervention;54–56 though the sheer number of patients who fall repeatedly means that such models are unlikely to reach most of those at risk without major investment.57,58 Some geriatricians have developed syncope clinics59 or specialist fracture liaison services.57,58 Many geriatricians offer specialist movement disorders and Parkinson’s disease clinics for older patients and fill a clear need and gap in doing so for patients who have become older and frailer.60–62
8. Specialist dementia, delirium and mental health services for older people. A high proportion of hospital inpatients have dementia, delirium, depression or other mental health problems.63–65 There has been continual improvement in the care of such inpatients including a focus on delirium management and prevention66,67 and on older peoples’ mental health liaison teams.68,69 Old-age psychiatry plays a key and often leading role (with geriatricians continuing to ‘own’ delirium more). Memory clinics and outpatient or community dementia services are largely run by old-age psychiatry in the UK but geriatricians are involved in a number of service models.
Liaison with other services
9. Orthogeriatrics. The typical hip fracture patient is over 80, usually with a history of falls or bone fragility, frailty and often complicated by delirium, dementia and poor mobility. There has been a revolution in the care of these patients over the past decade driven by the National Hip Fracture Audit, best practice tariff and a quality improvement movement co-driven by the BGS and British Orthopaedic Association.57,70 A range of benefits has arisen.70 Geriatricians are key to such models and there is enough work in big district hospitals to keep one or two of them busy all year.71 They also often oversee rehabilitation of inpatients with non-hip fractures and input into assessment of patients in fracture clinics – for falls and bone health risk.
10. Geriatric–surgical models or proactive care of older people undergoing surgery. Following the gains described for hip fracture patients, a growing number of geriatricians are involved in joint working with anaesthetists and surgeons around preoperative assessment and perioperative care of older people undergoing surgery. Interest in such models is growing.72,73
11. Geriatricians with oncology or palliative care. Palliative care is key to geriatricians’ work and some have sub-specialised in this. There is also a small but growing band of geriatricians involved in multidisciplinary support and comprehensive geriatric assessment for frail older people undergoing cancer treatment.74,75
Geriatricians as clinical champions
12. Geriatricians as system and service leaders.9,14,17,18,22,76 Geriatricians are often well placed for local clinical leadership roles. They interact daily with community health and social care systems as post-acute rehabilitation, discharge planning or admission prevention are central to their roles, and they are likely to have a whole system view and relevant relationships with community partners. We also see a large percentage of the medical take and hold a high number of beds, so are well placed to offer solutions around targets, delays, patient flow or readmission.
13. Geriatricians as safety champions. Many of the biggest safety incidents in hospital affect older people most.17,77 Not just falls,78 but pressure sores, hospital-acquired infections, drug errors or poorly planned discharges. Other harms of hospitalisation, such as immobility or delirium or loss of personhood and independence, are not usually recorded as safety incidents but they’re all too common.79–81 Movements such as the BGS/Health Foundation ‘Frail Safe’ project82 or the Scottish OPAC work20 aim to identify patients at highest risk and reduce these harms.
14. Geriatricians as educators and awareness-raisers. Given that geriatricians, specialist nurses, therapists, mental health practitioners or general practitioners (GPs) working with them can never see every frail older patient, yet such patients are to be found throughout adult medicine and surgery, we have a key role to educate and inform to ensure that colleagues have sufficient skills and information to improve their care and experience of hospitalisation.
Geriatricians in ‘hospital without walls’ roles: community geriatrics
15. Although a number of specialists (eg diabetologists) now provide care to patients in the community, as well as in hospitals, community geriatricians constitute the largest group of consultants working in the community.9,40,83 In some cases these roles may include improving healthcare for care home residents, as set out in recent BGS guidelines.84,85 This work can help reduce admissions from care homes or facilitate earlier return to them.86–88 They also work in community hospitals (where length of stay and outcomes are still very variable), both on wards and clinics; provide support to intermediate care and integrated locality teams, including crisis teams, falls response teams and virtual wards, for high-risk patients and support to GPs and community nurses (eg via telephone advice or home visits).14,17,89 In some parts of England, geriatricians are at the forefront of discussions with clinical commissioning groups regarding how such roles may develop into ‘new modes of care’,90 working with other providers of patients care to provide a seamless pathway of support for frail older people (whether in or out of hospital) when specialist expertise is required.
How ‘new geriatrics’ fits in with acute medicine and the RCP’s push to review GiM: a suggested way forward
Population ageing has changed modern hospital case mix for good.10,15,17–19,22–24 Patients with frailty, falls, dementia, delirium, declining mobility and functional impairment, poly-pharmacy and multiple comorbidities are now ‘core business’. Most acutely ill older patients require skilled rehabilitation and discharge planning, and are at risk of decompensation and disability if exposed to prolonged hospitalisation.50,76,91,92,93
The median age of acutely admitted patients is 71 and one-quarter of all bed days in English hospitals are in over 80s. In addition, 80% of all those staying in hospital over 14 days are over 65.16,17,93,94 Spend on acute care rises proportionately with patient age.95 One month, urgent re-admissions in over 75s now run at around 15%.96–98 Delayed transfers of care to step down health or social care facilities are rising with the majority of their clients being older.99 Increasing numbers of patients are admitted from nursing homes.17,86
With major pressure on hospital beds, big interhospital variation in admission rates and bed occupancy in over 65s and over 80s receiving the highest proportion of acute spend,18,19,95 we can’t solve system problems without focusing our efforts far more on older, complex patients.
The UK is fortunate and unique in having geriatric medicine as the biggest GiM speciality. However, it is clear that without a substantial increase in training numbers (bizarrely and unaccountably recently reduced for our specialty despite high numbers of new or unfilled consultant posts)100 and in funded consultant posts (many of which lay unfilled now despite being, alongside acute medicine, the most advertised) that geriatricians cannot look after every older patient with frailty.
We are also fortunate in having so many specialists who are dually accredited and highly trained in GiM. In turn, GiM is in effect largely acute medicine or acute geriatrics for the urgent ‘front door’ phase of care, with few other patients left who don’t fit more or less within one ‘organ speciality’ – though those patients often have a range of complex comorbidities requiring GiM or geriatric medicine skills. We tend to get annoyed at the assertion that ‘we are all geriatricians now’ merely because other specialists look after older patients. However, we do believe that alongside the expert workforce we need the rest to be adequately skilled and aware of the specific needs of older patients.
Of course, training and accreditation is one thing. Having doctors who really value and enjoy these elements of patient care is another.22,101 Too often, even in our system where salary scales are national and not speciality specific, they have been seen as less prestigious. This has to change as they are the key to unlocking whole systems of care. However, geriatric medicine requires access to and close to collaboration with a full multidisciplinary team, with a strong component around post-acute rehabilitation, discharge planning and comprehensive geriatric assessment. It also requires adequate access to community health and care services to prevent admission and facilitate earlier discharge. Such services are still not sufficiently available. By having this capacity, by a relentless focus on front door, early specialist review, rapid patient turnaround, minimising delays and seeing discharge and rehabilitation as core activities, and by having more specialists like geriatricians working across community interfaces, we could start to focus hospital activity more consistently on those patients who need specialist bedded acute care. This is likely to create bigger gains than a narrow focus on admission prevention as a holy grail.
Alongside this, our workforce planning should ideally increase the number of geriatricians and acute physicians, ensure some workforce flexibility so that some roles traditionally played by consultants might be taken up by skilled nurse practitioners, allied health professionals or GPs with a special interest. The Joint Royal Colleges Training Board is currently consulting on proposals following the Shape of Training review and General Medical Council proposals on generic competency training for future physicians.102,103 This gives us a golden opportunity to re-align education and training along the lines we have set out. It will also be necessary in future workforce modelling by organisations such as Health Education England, to shift towards these new models to plan for medical manpower across primary and secondary care in localities and the nursing and allied health professional workforce required to support them.104,105
However, the training and values of all physicians in acute medicine must reflect the needs of the ageing population, with person-centred rather than disease-centred care, and a whole pathway rather than hospital-centred approach. Continuity should be provided by ‘expert generalism’.
The future of any speciality or service model is subject to events and policy decisions none of us can predict. We feel the future of geriatric medicine in the UK remains secure. However, rapid population ageing, the desire to shift models of care closer to home and re-imagine primary care, and a desire to revive ‘expert generalism’ in acute and secondary care mean that everyone in adult medicine will have to acquire some degree of skill in the assessment and management of older people with frailty and complex needs, leaving geriatricians to focus on those patients for whom their skills add the most value. Meanwhile, when we talk about reviving general medicine, we need a growing realisation that in the future its core business will be acute internal and geriatric medicine.
