Abstract

Patients who would benefit from specialist mental health services for older people are often described locally as exhibiting ‘age-related complexity’. Despite the local origin of this term, the broader issue of complexity in old age is widely referred to in health policy and literature, but the absence of clear definitions for complexity or complex needs is compounded by the tendency for these terms to be used interchangeably with ‘frailty’ and / or ‘long term conditions’. This research explores how nurses construct the concept of age-related complexity and how that construction is manifested in practice.

The study, carried out in an NHS mental health trust in NE England, was shaped by social constructionist and critical gerontology theoretical perspectives, using a constructivist grounded theory approach. Data were collected through ‘loosely guided interviews’ with thirteen registered nurses working with older people. Purposive and theoretical sampling were used. Data were analysed using the constant comparative method.

The study found that nurses construct complexity as the interaction of needs across a number of internal or external domains. Nurses identify important differences between complexity and frailty. Different nursing approaches may be required accordingly. Significantly, complexity is constructed as a dynamic state from which older people can ‘recover’.

Nursing complex older people is characterised by feelings of stress, frustration, worry and sometimes satisfaction. Nurses can develop ‘deep relationships’ with complex older people which share the characteristics previously described as ‘connected relationships’ (Morse 1991). Nursing work with complex older people involves emotional labour, is invisible to others and remains under-valued.

This research contributes an understanding of complexity and frailty in old age from a nursing perspective, and adds a mental health dimension to the model of nurse-patient relationships previously developed by Morse (1991), identifying implications for practice. Areas for further research on complexity in old age are suggested.

Glossary

Agenda for Change – the framework that determines pay and conditions for most NHS staff in England

Assertive outreach – an approach to providing mental health services to people who have severe mental illness and are hard to engage with. People who are offered assertive outreach are usually working age (18-65 years old) and usually have a diagnosis of schizophrenia. Mental health workers work in teams who share responsibility for patients, have very small caseloads and seek to engage on the patient’s terms, often ‘flexibly and creatively’ (Addis & Gamble, 2004). For example, this might mean meeting the patient in a café rather than a clinic or making multiple attempts to meet the patient rather than issuing set appointment times.

Case management – a pro-active approach to managing the health of people (usually with long-term conditions) in the community. One of the aims is to intervene early to prevent the need for hospital admissions or admission to a care home.

CGT – Constructivist grounded theory

Community matron - a senior community nurse who works with people (all ages) who have long-term or complex health conditions to prevent emergencies (usually community matrons do not include people with long term mental health problems).

CPA – Care Programme Approach. CPA was first introduced in the UK in 1990 and requires health and social care providers to deliver care for mentally ill people in the community in a specific way. The four principles of assessment, care plan, a care co-ordinator and review together with involvement of the person using the service, and where appropriate, their carer are the essential elements of the approach.

CPN – Community Psychiatric Nurse – a registered mental health nurse who works with people in their own homes and communities.

Functional illness – a broad category describing mental illnesses (usually in older people) that have primarily a psychiatric or psychological cause. These include schizophrenia, depression, bi-polar disorder, anxiety disorders and less commonly phobias and obsessive-compulsive disorders.

Intermediate care – a range of services provided in residential or community settings that aim to promote faster recovery from illness, early discharge from hospital or prevent the need for hospitalisation. Intermediate care services are usually provided for a time-limited period (about 6 to 8 weeks).

NHS – National Health Service

MHSOP – Mental Health Services for Older People; a clinical directorate within the mental provider organisation (trust) providing services to people predominantly over the age of 65 years.

Organic illness – a broad category describing mental illnesses that have a biological or physiological cause. The dementias are the main group of illnesses in this category, which also includes delirium and less common conditions such as organic depression and organic hallucinosis.

Personalisation –an approach to care delivery initiated in adult social services which seeks to tailor care to the needs of individuals rather than fitting them into existing services. It is predicated on giving individuals choice about the care they receive (Carr, 2010)

Person centred care –first described in relation to the care of people with dementia by Tom Kitwood, person centred care describes a philosophy and approach that values people with dementia, and their carers; treats them as individuals, attempts to look from the perspective of the person with dementia and seeks to provide a positive social environment that contributes to wellbeing (Brooker, 2004)

Recovery model – a philosophy that underpins mental health care in the UK, the recovery model focuses on a person’s strengths, engenders hope and attempts to promote social inclusion, this reducing the stigma associated with mental illness

Support worker – a health worker who has not professionally trained or registered with a governing professional body.

Author’s note

I have deliberately chosen to write this thesis in the first person where appropriate. Whilst recognising that most academic theses are not presented in this way, I am conscious that the first person is a powerful literary device that I hope, will assist in the process of making my role as researcher explicit. This choice is consistent with a constructivist approach in which the researcher is positioned as partner to the participants rather than a detached and objective outsider (Mills, Bonner & Francis, 2006a). In addition, I have deliberately attempted to avoid reference to ‘patient’ throughout this thesis, using ‘older person’ instead where possible. I made this choice for a number of reasons. Firstly, since I was only interested in talking to nurses about older people they had worked with, all the older people they talked about would be patients or carers. Secondly, I believe that the use of ‘older person’ will serve continually to remind the reader that the study is about older people. The exceptions to this convention are in transcription excerpts where nurse participants used the term ‘patient’ during their interviews my subsequent discussion of these excerpts and when discussing the work of other authors who use the term ‘patient’.

I have included a ‘key messages’ box at the end of each major section in the text. This technique is borrowed from professional health journals and is intended to remind the reader of the most salient issues raised in the section.

Introduction

Chapter 1:Introduction and background

1.1Introduction

This thesis sets out to report a study whose aims were to explore how registered nurses working in secondary mental health services construct ‘age-related complexity’ and how their constructionsare played out in practice. The main objective was to co-construct nurses’ experiences and understandings and use these to develop a substantive theory of ‘age-related complexity’.

Whilst health policy recognises that some older people have ‘complex needs’ there are only superficial descriptions of how such complexity is defined, how it is recognised, how it affects nursing practice and the experiences of nursing older people with complex needs.This research is driven by a local need to interpret and implement national policy relating to older people with mental health needs. The contribution of knowledge to this area has the potential to inform service decisions made at strategic and clinical levels; for example, at a strategic level it may add to the debate about how mental health services for older people should be structured and delivered. At the same time the research has potential clinical utility; for example in helping to clarify clinical decision making and explain the experiences of nurses working with older people who have complex needs. Thusit may point to ways to improve nursing practice.

This chapter will set the scene for the study within the context of national policy and the local service delivery. It begins by explaining the demographic context, then gives both an outline of mental illnesses common in older people and a brief history of health services for older people, followed by a review of health care policy relating to older people, mental health and nursing. It then moves on to outline the setting in which the research took place, the origins of the research and the researcher’s own professional background. The chapter concludes with a summary highlighting the rationale for, and the importance of, the study.

1.2Origin of the term ‘age-related complexity’

The term ‘age-related complexity’ emerged locally (circa 2006) following debate between senior clinical leaders from older people’s mental health services and those from working age adult services. It was intended to help describe the distinct role that older people’s mental health services played in a health care context that was moving towards needs-led rather than age-led care. In essence then, it seems that the clinical leaders were setting out their position and declaring what they saw as the unique role for their services (R. Briel, personal communication, 21st March 2010). There was, however, a fundamental flaw in this position. The term ‘age-related complexity’ was not defined, nor was there any assurance that there was a common understanding of it, other than amongst the senior clinical leaders (who were doctors). In addition, there was no way of assessing for, or measuring ‘age-related complexity’. This study was encouraged by the (then) Clinical Director for older people’s mental health services as a step towards clarifying how ‘age-related complexity’ should be defined and used as a concept in practice. Despite having had a local origin, I believe that the study of age-related complexity is important and has relevance beyond the local service for reasons that I will now consider.

1.3 Background

1.3.1Demographic trends

There is no doubt that the population of the UK, like that of other developed nations, is ageing (see for example, Smith et al, 2005). There are many illustrative statistics quoted widely in policy and literature, some of which are shown in Figure 1.

Figure 1: Selected demographic statistics relating to older people.

In some circles these statistics have led to predictions characterised by the use of alarmist terms such as ‘the demographic time-bomb’ (Ellson, 2009) or ‘the greying population’ (Smith et al, 2005). The predicted impact of these changes on the UK economy has led to a number of responses, for example the raising of retirement age and a campaign to encourage employers to consider the value of older employees (Department of Work and Pensions, 2009).
