Background: End of Life Care at home
• Spending time with loved ones, pain control, and being cared from in their preferred place are among the top priorities for people at the end of life (Engelberg et al. 2005)
• Surveys of the general public and dying people suggest the majority would prefer to die at home (Gomes et al. 2013)
• 51% of deaths in hospital in England in 2011, with only 22% of deaths at home
• The 2011 VOICES survey asked bereaved relatives whether the person who died had enough choice about where they died: Hospital 29% yes, care home 53%, hospice 70%, home 88%.

Evaluation: The Marie Curie Nursing Service (MCNS)
• Service model: home-based end-of-life nursing care delivered my registered nurses and healthcare assistants, most often 9 hour shifts of overnight care. 30,000 patients per year across UK.
• Longstanding belief: MCNS enables more people to die at home and reduces the amount of time they spend in hospital
• Evidence gaps:
• How many MCNS patients die at home? Service data has gaps.
• How much time do MCNS patients spend in hospital?
• What is a fair comparison? We know ≠ ‘general’ dying population
• Aim: To evaluate the impact of Marie Curie Nursing Service care on place of death, hospital use and costs at the end of life

receive service
(everyone else)

Matched control studies – broad aim
>1M individuals - died Jan 2009 to Nov 2011, did not
receive service
(everyone else)
Aim to find 30,000 individuals who match
almost exactly on a broad range of
characteristics
Use these people as study control group

Stages in matching process
• Construct longitudinal histories for agreed time periods and estimate costs
• Match on selected variables eg time to death; age; gender; deprivation health conditions/diagnoses; cancer type and history, prior hospital use (IP, OP and A&E)
• Select cases with the best match
• Compare hospital activity and costs

Conclusions
• Evaluation of large-scale, existing end-of-life care service using
well-matched controls
• Those who received home-based nursing care:
• Much more likely to die at home
• Lower use of hospital care
• Lower hospital costs
• Impact of MCNS care greater for those without cancer –
surprising finding, although literature limited
• Results confirm previous work on benefits of home-based
support but added significance from numbers studied and the
breadth of service provision
© Nuffield Trust
Conclusions (continued)
• Caveats:
• Other costs – reduction in hospital costs considered against
other costs (including MCNS care), and possible increased
used of other services (e.g. GPs, community services & social
care)
• Unobserved confounders – although groups well-matched,
there may have been unobserved factors not recorded in
routine data influencing suitability for home-based end-of-life
care, e.g. personal preferences, availability of family/carer
support etc.

Impact for Marie Curie
Understanding our patients
• Much richer understanding of demographic profile, clinical
characteristics and outcomes for MCNS patients
• Outcomes for patients with and without cancer of great interest
Commissioning
• Can demonstrate, for the first time, that service reduces hospital
costs and increases the number of home deaths
• Breakdowns by service type enable us to build much more
robust business cases for the potential impact of new services

Impact for Marie Curie
‘The report clearly shows that specialist nurses support patient choice, reduce unwanted hospital admission and also appear to realise significant savings.
Nurses see too many instances of patients at the end of their life having to come into hospital, often at night and against their best wishes. This obviously causes distress to individuals and families.
The NHS needs to sustain investment in this specialist, out of hours care, so that wherever and whenever a person dies, they can be given excellent pain-relief, dignity and care.’
