Overview of NICE guidance on excess winter deaths and illness and the health risks associated with cold homes
Dr David Sloan, formerly chair of NICE Public Health Advisory Committee ESRC seminar. Doncaster 27 June 2016
Overview
• Context
• A little about the NICE process
• The evidence about the impact of cold weather on health
• The NICE guidance and quality standard
Context
• Poverty and inequity are health issues (Marmot etc.)
• Cold weather causes an increase in illness and death
• Fuel poverty causes double jeopardy
• Policy and initiatives on carbon saving, public health,
housing and poverty do not always align at national or
local level
It was in this context that NICE was asked to look at
Excess Winter Death and Illness.
Referral from the Department of Health
NICE was asked to produce: “Guidance for commissioners and practitioners working in local authorities and health services on effective implementation and delivery of approaches for prevention of excess winter deaths and morbidity and the health risks associated with cold homes. Focus specifically on vulnerable children and older people to promote and protect their health and wellbeing both in the short and longer term.
The guidance would aim to define the systems required for an integrated approach to identification of risk and vulnerability and the provision of effective interventions (including insulation, fuel tariffs, uptake of benefits, and heating improvements)… it would also be helpful if you could consider including the specific issue of excess winter deaths in rural areas.”
The NICE process
• Defined “scope” based on referral and consultation
• Reviews of evidence of effectiveness and economics
(London School of Hygiene and UCL)
• Best available evidence, wide trawl
• Public Health Advisory Committee discussions
• 3 month public consultation on draft guidance
• Open process; public meetings and stakeholders able to
comment at each stage
• Final guidance launched 5 March 2015
The evidence
• The nature of evidence – research literature; testimony
• Clear link between cold weather and increase in illness
and death from all causes
• Greatest burden cardiovascular and respiratory disease
but also other groups – mental health, disability etc.
• Greatest impact in coldest homes (Joseph Rowntree)
• UK has greater problem than e.g. Scandinavia
• Therefore strong inference that tackling cold homes and
fuel poverty will reduce excess deaths and illness
Evidence (2)
• Death rate rises when Temp drops to 5-8 Deg C
• Time lag – effect continues for weeks
• For every death, 8 admissions and unmeasured illness
at home
• Cost to NHS alone £1.36 billion (Age UK)
• Variation in practice, with many examples of innovation
and good practice and coordinated local initiatives

International comparisons
Limitations of the evidence
• Mostly time series studies at population level and based
on external temperature
• Few studies on individuals or using internal temperature
• While evidence of link with cold is clear, evidence of
what interventions work is more limited
• Reliance on modeling for economic evidence
• Little evidence on behaviour – trade offs, self disconnect
etc.
• Inequalities exist but little evidence about solutions
The NICE recommendations; the
headlines of NG6
• A key public health issue requiring whole year planning
• Single point of contact for tailored health and housing
advice
• Identify and focus on those most at risk
• Make every contact count
• Plan for discharge; never to a cold home
• Training; raise awareness of public and practitioners
about the impact of the cold on health
• Make use of the non health and social care workforce
• Compliance with building regs – e.g ventilation
• Research recommendations
Recommendation 7
“Discharge vulnerable people from health or social
care setting to a warm home”
–Early assessment of vulnerability and risks
–Planned discharge to include consideration of heating
–Referral to single point of contact health and housing service if
necessary
NICE Quality standards QS117
• Describe high priority areas for quality improvement in
specific aspect of public health, health or social care
• Quality improvement tool for use by NHS and others
• Seven quality statements. No 6 says:
“People who are vulnerable to the health problems
associated with a cold home who will be discharged to
their own home from hospital, or a mental health or
social care setting have a discharge plan that includes
ensuring that their home is warm enough.”
Using the Guidance and Quality
Standard
• Useful when negotiating locally and nationally – has
NICE stamp
• Helps others (e.g. NHS orgs) meet performance targets
• Helps focus on where action is likely to help (evidence)
• Some practical ideas
www.nice.org.uk/guidance and look for NG6
Conclusions
• There is much that can be done
• Several potentially congruent policy initiatives which
could be catalysts for coordinated local action:
– Cold weather plan, environmental policies to reduce fuel use,
drive for energy efficiency and the reduction of fuel poverty,
benefits programmes
• National policy provides framework but effective action
depends on good local coordination
• We need better evidence, especially of interventions so
please get your evaluations published!
