Optimum hospice at home services for end-of-life care: protocol of a mixed-methods study employing realist evaluation

'For Want of a Nail': developing a transparent approach to retroduction and early initial programme theory development in a realist evaluation of community end of life care services

A crucial part of theory-driven realist thinking is retroduction, the process of looking backwards for explanation of how and why things may be. Conducted early in the realist evaluation process, it provides a foundation for evidenced 'theory gleaning'. Despite retroduction being an inherent part of the realist process, it is often 'hidden' in realist reports. This paper explains the thinking behind, alongside an example of, a framework created by the authors to make transparent the retroductive process as used in a realist evaluation of two community End of Life Care services. The approach makes visible the application of the 'sociological imagination' and lends robustness to hypotheses by establishing how the authors utilised: wide-ranging potential generative causation; stakeholder and Patient and Public Involvement feedback; literature scoping; and substantive theories at the middle range, specifically Transitions Theory. These stages led to the development of Initial Programme Theories, with a clear history of genesis.

Hospice at Home services in England: a national survey

OBJECTIVE

Hospice at Home (HAH) services aim to enable patients to be cared for and die at home, if that is their choice and achieve a 'good death'. A national survey, in 2017, aimed to describe and compare the features of HAH services and understand key enablers to service provision.

METHODS

Service managers of adult HAH services in the 'Hospice UK' and National Association for Hospice at Home directories within England were invited to participate. Information on service configuration, referral, staffing, finance, care provision and enablers to service provision were collected by telephone interview.

RESULTS

Of 128 services invited, 70 (54.7%) provided data. Great diversity was found. Most services operated in mixed urban/rural (74.3%) and mixed deprivation (77.1%) areas and provided hands-on care (97.1%), symptom assessment and management (91.4%), psychosocial support (94.3%) and respite care (74.3%). Rapid response (within 4 hours) was available in 65.7%; hands-on care 24 hours a day in 52.2%. Charity donations were the main source of funding for 71.2%. Key enablers for service provision included working with local services (eg, district nursing, general practitioner services), integrated health records, funding and anticipatory care planning. Access to timely medication and equipment was critical.

CONCLUSION

There is considerable variation in HAH services in England. Due to this variation it was not possible to categorise services into delivery types. Services work to supplement local care using a flexible approach benefitting from integration and funding. Further work defining service features related to patient and/or carer outcomes would support future service development.

A new tool to measure acuity in the community: a case study

The provision of acute healthcare within patients own home (i.e. hospital in the home) is an important method of providing individualised patient-centred care that reduces the need for acute hospital admissions and enables early hospital discharge for appropriate patient groups. The Hospital in the Home (HitH) model of care ensures that this approach maximises patient safety and limits potential risk for patients. As HitH services have seen record numbers of patient referrals in the past 2 years, there is now a greater need to measure and understand the acuity and dependency levels of the caseload. Through an expert clinician development process at one NHS trust, aspects of procedural complexity, interdisciplinary working, risk stratification and comorbidities were used to quantify acuity and dependency. This paper uses a case study approach to present a new method of measuring this important concept.

The Cost of Visit-based Home Care for up to Two Weeks in the Last Three Months of Life: APilot Study of Community Care Based at a Hospice-at-home Service in South East of England

The cost of visit-based community care based around a 24/7 hospice-at-home (HatH) service in the last 3 months of life was assessed. Thirty families completed a health and social carediary of at-home visits over two-weeks following contact with the HatH night service. Diaries captured 333 days of care provision, averaging 11 diary days per family, 708 health care professional and carer visits, lasting 604 hours at a cost of £20,192 ($24,946). Hat H care, integrated with community support, seems an economic proposition but highlights the complexities of assessing cost of end of life care.

Understanding what works, why and in what circumstances in hospice at home services for end-of-life care: Applying a realist logic of analysis to a systematically searched literature review

BACKGROUND

We have undertaken a systematically searched literature review using a realist logic of analysis to help synthesise the diverse range of literature available on hospice at home services.

AIM

To find out in the existing literature what features of hospice at home models work best, for whom and under what circumstances.

DESIGN

A realist logic of analysis was applied to synthesise the evidence focusing on mechanisms by which an intervention worked (or did not work). An initial programme theory was developed using the National Association for Hospice at Home standards, Normalisation Process Theory and through refinement using stakeholder engagement.

DATA SOURCES

PubMed, Science Direct, AMED, BNI, CINAHL, EMBASE, Health Business Elite, HMIC, Medline, PsychINFO, SCOPUS, Web of Science, DARE, Google Scholar, NHS Evidence, NIHR CRN portfolio database, NIHR journal library of funded studies, including searches on websites of relevant professional bodies (August 2014, June 2017, June 2019).

RESULTS

Forty-nine papers were reviewed, of which 34 contributed evidence to at least one of the eight theory areas: marketing and referral, sustainable funding model, service responsiveness and availability, criteria for service admission, knowledge and skills of care providers, integration and coordination, anticipatory care, support directed at carers.

CONCLUSIONS

Our literature review showed how it was possible to develop a coherent framework and test it against 34 published papers and abstracts. Central to this review was theory building, and as further evidence emerges, our programme theories can be refined and tested against any new empirical evidence.
