Objectives: To identify doctors' perceptions of the need for palliative care for heart failure and barriers to change.
Design: Qualitative study with focus groups.
Setting: North west England.
Participants: General practitioners and consultants in cardiology, geriatrics, palliative care, and general medicine.
Results: Doctors supported the development of palliative care for patients with heart failure with the general practitioner as a central figure. They were reluctant to endorse expansion of specialist palliative care services. Barriers to developing approaches to palliative care in heart failure related to three main areas: the organisation of health care, the unpredictable course of heart failure, and the doctors' understanding of roles. The health system was thought to work against provision of holistic care, exacerbated by issues of professional rivalry and control. The priorities identified for the future were developing the role of the nurse, better community support for primary care, and enhanced communication between all the health professionals involved in the care of patients with heart failure.
Conclusions: Greater consideration should be given to the care of patients dying with heart failure, clarifying the roles of doctors and nurses in different specialties, and reshaping the services provided for them. Many of the organisational and professional issues are not peculiar to patients dying with heart failure, and addressing such concerns as the lack of coordination and continuity in medical care would benefit all patients.

What is already known on this topic Patients with heart failure have unmet needs for health care at the end of life Specialist palliative care services see few patients with heart failure The national service framework for coronary heart disease endorses the provision of palliative care for heart failure Little evidence exists on how this care should be provided, and doctors' views are not known What this study adds Barriers to adopting a palliative care approach in heart failure care relate to the current organisation of health services, the difficulties of prognostication, and doctors' understanding of roles and responsibilities Doctors believe that the general practitioner should be the central figure in palliative care for heart failure, supported by specialists Doctors' future priorities are developing the role of nurses, increasing essential community services, such as district nursing, and improving communication with colleagues

	Introduction

Top Abstract Introduction Participants and methods Results Discussion References

Heart failure is a common condition; estimates of prevalence range from 2 to 10 per 1000 population, and the incidence is rising as more people survive acute coronary events.¹ The median survival for heart failure (16 months after first hospital admission, unadjusted) is worse than for many of the common cancers.² Despite this poor outlook, those who die of the condition in the United Kingdom seldom access specialist palliative care services, and responsibility for their care lies with primary care, cardiology, geriatrics, or general medicine. Palliative medicine grew out of the hospice movement, and cancer charities still make a substantial contribution to the costs of palliative care. This, coupled with professional doubts over the wisdom of expansion, means that specialist care of the dying is virtually synonymous with cancer care in the United Kingdom.³

In recent years, however, there have been calls to recognise the needs for palliative care of people with heart failure.^4-6 The national service framework for coronary heart disease endorsed this view but failed to address the question of how it should be provided or to identify new sources of funding.⁷ As the research evidence for unmet needs of care in terminal heart failure grows, it has not been accompanied by investigation into appropriate models of care.^6-8 Patients dying with heart failure may have unpredictable illness trajectories; understanding and expectations will also be different to patients with terminal cancer. The needs of health professionals for support and experience with palliative care for heart failure are also likely to vary. Box 1 suggests aspects of palliative care that may not be readily available to patients with heart failure.

In the absence of an evidence base, doctors' views on terminal care for patients with heart failure are likely to be influential in shaping the development of future care. In our study we used focus groups to explore doctors' views of palliative care for patients with heart failure, and we aimed to identify barriers to improving the care of this patient group.

	Participants and methods

Top Abstract Introduction Participants and methods Results Discussion References

Our study was exploratory owing to the paucity of research, therefore focus groups provided an appropriate approach. Apart from being an efficient means of data collection, focus groups allowed the participants to use their own frames of reference and to identify the topics that were important to them. Clarification of views through discussion and debate was particularly valuable for a topic to which the participants may not have given much prior consideration.

Sampling
We recruited seven specialty groups of doctors; two each of general practitioners and consultant cardiologists and one each of consultants in geriatrics, general medicine, and palliative medicine. These were chosen to reflect the specialties that are most concerned with patients with heart failure. We included doctors from tertiary referral centres (one cardiologist group), teaching hospitals, and district general hospitals to ensure access to a wide range of views. One general practitioner group was made up of doctors with either a teaching or research post at a university. We took a pragmatic approach to recruitment, and participants were found from several different sources, depending on circumstances (table).

Data collection and analysis
The focus group meetings lasted an average of 80 minutes. We developed a topic schedule to address our aims, using published literature and our own experiences. The groups were also encouraged to raise their own issues. The same facilitator and observer attended all the meetings, which were tape recorded and transcribed. These two researchers then coded all the transcripts with Nvivo software.¹² The data were analysed by using the principles of constant comparison.¹³ The tapes were scrutinised before examining the transcripts and for checking of final interpretation. Emerging themes and categories were identified independently, and agreement was reached by discussion. The researchers were from different disciplines, and only one had prior knowledge of the area of research. The reliability of the findings was enhanced further by scrutiny from the steering group, which included practising clinicians.

Organisational barriers
The workings of the system were a concern for many of the hospital doctors (box 2). Care for patients dying with heart failure was described as uncoordinated, with patients going from hospital to community and back again. Repeated admissions to different consultant teams were common, and patients' medical notes were sometimes said to arrive on the wards after the patient had been discharged or died. A picture emerged of poor quality care for the patients and frustration for the doctors. The lack of continuity in current medical practice was highlighted by the geriatricians and palliative care doctors. All the groups thought that poor support in the community contributed to repeated hospital admissions. Adequate basic services, such as district nurses and social services, were a higher priority than more sophisticated forms of palliative care. Although hospital colleagues empathised with the general practitioner struggling to cope without support, the palliative care doctors and cardiologists were also concerned about the impact of the quality of care provided by general practitioners.

Implicit in the discussions was that care for people dying with heart failure had not been planned. This was most clearly expressed by the cardiologists, who acknowledged the need to develop those formal and informal connections between specialties that are essential to coherent care. All the groups suggested that different models of care in the community might be needed. The concept of a key worker was raised as a possible solution by both general practitioners and cardiologists. This is a model seen in psychiatry, whereby a member of the team coordinates and oversees the care received.

Prognostication
Unlike with cancer the diagnosis of heart failure does not begin with bad news, and when to initiate palliative care is a difficult question that was discussed by all the groups. The path of chronic heart failure is unpredictable, with half of patients dying suddenly (box 3). Stories were told of patients being admitted near to death and being "pulled back from the brink." Other patients were perceived as being quite well but able to switch to being terminal rapidly.

The uncertain prognosis of heart failure meant that doctors were concerned about the impact on the patients of giving bad news too soon. This was termed the "therapeutic and anti-therapeutic" use of prognostication by one general practitioner, and it generated different concerns in the groups. The major fear of the cardiologists was saying the wrong thing and the patients "losing faith" in their professional carers, whereas the general medicine doctors did not want to see the patients give up the fight for life. The wider implications for the family and carers were raised by the general practitioners.

Increasing openness about prognosis brought with it growing demands on doctors, and patients were thought to need a lot of psychological support. Doctors in all groups portrayed themselves as bad prognosticators, admitting that they may accept the poor outlook late in the illness. Patients, carers, and nurses were all suggested as more realistic predictors. As the beneficial effects of open communication in terminal care were acknowledged, this may have represented an unwillingness to engage with difficult issues.

Doctors' roles
Although many participants agreed that the general practitioner is a central figure in palliative care for heart failure, there was some questioning of the appropriateness of the involvement of specific groups. The most severe criticism was reserved for the cardiologists, who were charged by all groups with failing to recognise palliative care needs or practise holistically. In contrast to their colleagues' image of them, the cardiologists articulated an approach supporting teamwork, common goals, and a willingness to involve whoever had the appropriate skills. They also seemed to place most importance on dialogue between the specialties to improve care in the future. The palliative care doctors were generally viewed favourably by their colleagues, although the need for their specialty was questioned by some general practitioners, who felt able to manage their own dying patients. For these general practitioners, the palliative care specialists were inaccessible or liable to "steal" the general practitioners' patients. The general practitioners saw themselves at the centre of things, both providing and coordinating care. This was echoed by the geriatricians, who argued for care provided by community services, supported by others (box 4). The perceived inability of palliative care doctors to manage heart failure competently and the unwillingness of cardiologists to provide palliative care were used to justify this approach.

The future
Our participants invested some hope in the national service framework as a means of increasing funding in palliative care for heart failure. A need for discussion and links between specialties was acknowledged chiefly by the cardiologists. In contrast, all the groups talked at some length of an enhanced role for nurses (box 5). The nurse was seen as a figure who could follow patients into the community after discharge from hospital, liaise between primary and secondary care, ensure that treatments were adhered to, and mobilise appropriate support.

	Discussion

Top Abstract Introduction Participants and methods Results Discussion References

Greater consideration is needed towards the care of patients dying with heart failure, clarifying the roles of health professionals in different specialties. Doctors in our study did not dispute the place of palliative care for patients dying with heart failure. However, we identified important potential barriers to the development of a palliative care approach to this patient group. These barriers arose from three main areas: the organisation and delivery of services, the course of heart failure, and doctors' views of their colleagues' roles.

Strengths and limitations
From the outset our study was intended as a forerunner to research with nurses, patients, and other groups across the United Kingdom. Doctors were chosen as a starting point because of their role in shaping demand for services. However, we acknowledge that a study involving one professional group cannot expect to generate anything other than cautious conclusions about a multidisciplinary subject such as palliative care.

Our study was novel and made appropriate use of focus group methods to generate issues for further investigation. Our pragmatic approach to recruitment is justified by the pressures on clinicians' time and low response rates to research studies. However, as participants in our study gave their time voluntarily, it is likely that they were more motivated and interested than average. By using single specialty groups we aimed to minimise the impact of power relations between the interviewees and to limit the disparity between their public and private accounts. The data were analysed by a medically qualified doctor and an experienced qualitative researcher. The high level of agreement between the themes generated independently by researchers with different perspectives increases our confidence in the results.

The findings point to the need for health professionals to give greater thought to the care of patients dying with heart failure, clarifying the roles of doctors and nurses in different specialties and possibly reshaping the services provided. Clearly, these are the priorities of doctors, and they may not reflect accurately the patients' experiences. Investigations into the concerns of patients dying with non-cancer diagnoses have tended to focus on the impact of the disease on the individual, rather than organisational issues. ^{8 14 15} However, patients with heart failure have been shown to have worse access than patients with cancer to a range of community services, even when attending a dedicated clinic. These patients also identified a need for their professional carers to improve their dialogue with each other.¹⁶ Prognostication in heart failure is particularly uncertain, but other problems are shared by patients with chronic progressive conditions. Studies of patients with chronic obstructive pulmonary disease have highlighted similar lack of continuity in care and the need for a more holistic approach. ^{17 18} Communication with doctors is a common source of dissatisfaction for patients of all diagnoses needing palliative care. ^{8 19 20}

Implications
Our participants gave graphic descriptions of the inability of the National Health Service to deliver what they saw as an acceptable level of care to this patient group. Many of the issues they raised were not specific to the care of heart failure, or even to end of life care. Correcting such a failure of the system and challenging attitudes that inhibit collaboration are long term goals. In the short term it is likely that practical solutions for some of the component problems would improve the lot of patients dying with heart failure. Greater use of information technology could ameliorate some of the organisational deficiencies described, for example. Most of the doctors in our study were enthusiastic about developing the role of the nurse in terminal heart failure. They described an often superior ability of the nurse to liaise with other specialties and to communicate with the patients. Underlying this is a dilemma often seen in general practice, that of balancing a desire to maintain ownership of an area of care, with existing heavy workloads. The solution proposed goes some way towards avoiding the competing claims to holism among medical specialties. A nurse with expertise in cardiac palliative care is ideally placed to act as a coordinator of services, as well as influencing medical practice. However, delegation, rather than empowerment, does not remove the question of which specialty should take the lead. In recent years several nurses have been appointed to work with patients with heart failure, usually attached to a hospital cardiology centre. Research suggests that specialist nurses may reduce the number of hospital readmissions and improve disease management for patients with heart failure discharged back to the community. ^{9 10} A role in palliative and terminal care has yet to be defined, although specialist palliative care nurses such as those from the Macmillan service provide a successful model that could be adapted.

As the palliative care needs of patients with heart failure are acknowledged, the demands on health and social care services in the community are likely to increase. Furthermore, there is growing recognition that palliative care services need to be integrated into primary care.²¹ Recent changes in the NHS, such as the introduction of joint commissioning by health and social services and the development of primary care trusts, may, in the long term, herald a more favourable attitude to developing community support for patients with heart failure. While primary care trusts are in their infancy it may prove difficult for them to innovate and develop services. Although primary care trusts are to control about three quarters of the NHS budget, they are immature organisations, with unproven processes and inexperienced staff.²² It also seems unlikely that palliative care for heart failure will be a high priority compared with many other targets that are explicitly highlighted in national service frameworks. However, with the prevalence of heart failure increasing, planning for the needs of people dying with heart failure in the NHS must become a priority issue.
