Compulsory treatment  user choice?
Stigma & discrimination  social exclusion
Family impacts  often hidden; incentives?
Crime  exaggerated societal reactions?
Mental well-being  links to happiness
Leading mental health policy themes
a.
Wider NHS and social care structures - financing; commissioning;
competition … few MH-specific issues.
b.
Coordination - getting health and other systems to work together
more effectively and efficiently
c.
Prevention of mental illness; and promotion of mental wellbeing.
d.
Early intervention – life-course perspectives etc
e.
Roles of hospitals (and other institutions) - appropriate housing
support; community care
f.
Personalisation – responding to individual needs and preferences;
hence personal budgets etc
e.
f.
g.
h.
Employment, including welfare payments, absenteeism, presenteeism
Social inclusion – rights, opportunities, participation etc
Equity – vicious cycle linking deprivation to morbidity
Ageing and implications for not just dementia but also psychoses,
depression
Stigma and discrimination (at the root of many challenges?)

Our approach - 1
Aim - model the costs and economic pay-offs of initiatives to
prevent mental illness and promote mental well-being.
o
Looked at evidence-based mental health interventions
(incl. non-NHS) – must have well-established outcomes
o
Looked at 15 different areas and interventions
o
Used simple decision analytic modelling
o
Close liaison with DH officials; consultation with experts
As far as the robust evidence base allows:
o
Included promotion, primary, secondary prevention
o
Looked at widest range of economic impacts
o
Estimated impacts over long time periods
o
If in doubt, we adopted conservative estimates
Our approach - 2
o
Examined interventions from 2 perspectives:
- pay-offs to society as a whole and
- cash savings to the public sector
o
And interested particularly in the timing of impacts and
whether (or when) ‘cashable’
o
Over and above the economic pay-offs there are health and
QOL benefits to individual patients
Important to note that …
a.
These are simple, partial and incomplete models
b.
Findings are not definitive: they provide a platform for
discussion (hence publication on DH website and linked
elsewhere)
c.
Interventions modelled are not necessarily the only ones that
are economically attractive
d.
BUT every intervention has ‘proven’ health/wellbeing benefits
Debt: mental health challenges
Prevalence of mental health problems
• 45% of people in debt have mental health problems
compared with 14% not in debt
Incidence of mental health problems
• Developing unmanageable debt is associated with an
8.4% risk of mental health problems compared to
6.3% for people without financial problems
Specific conditions
• Alcoholism (2x), Drug Addition (4x), Suicidal ideation
(2x)
Source: Fitch et al, submitted; Meltzer, et al., 2010; Skapinakis et al., 2006;
Debt counselling: the economic case
Target
General population without mental health problems who
are at risk of unmanageable debt
Intervention
Debt advice services, provided on face-to-face,
telephone or internet basis
Outcome
evidence
Unmanageable debt increases risk of developing
depression/anxiety disorders by 2% in general
population. Face-to-face service alleviates 56% of
unmanageable debt; telephone service alleviates 47%.
Economic
pay-offs
Reductions in: health and social care service use; lost
employment; legal system costs; costs to local economy
Findings
Complicated …! Savings depend on who pays, mode of
delivery, and amount of debt recovered. Telephone/web
advice cost saving (most scenarios). Face-to-face advice
most cost-effective. If 2/3 of service costs recovered
from creditors, then total savings = £0.63 per £1
invested in first year; and £3.55 over 5 years.
Knapp et al (2011) in Knapp et al Mental Health Promotion…, Dept of Health.
Medically unexplained symptoms: the
economic case
Target
Individuals with sub-threshold somatisation and clinical
somatisation disorders in primary care (account for c.
25% of all primary care consulters)
Intervention
Referral to 10 sessions of cognitive behavioural therapy
over 6-month period; cost = £400
Outcome
evidence
CBT shown effective in reviews; 35% of individuals
report improvement in symptoms after 15-month
follow-up (Allen et al 2006)
Economic
pay-offs
Reduced NHS costs (GP consultations, prescriptions,
A&E, outpatients, inpatients); reduced sickness
absence from work
Findings
Total savings over 3 years = £1.75 per £1 invested for
comprehensive programme; savings = £7.82 per £1
invested for targeted programme. Majority of savings
accrue to NHS
McDaid et al (2011) in Knapp et al Mental Health Promotion…, Dept of Health.
Early detection of psychosis: the
economic case
Target
Young people aged 15-35 in general population with
prodromal symptoms of psychosis. Estimated number
per year = 15,763.
Intervention
Early detection service (based on OASIS in South
London; Valmaggia et al 2009). Consists of
psychological and pharmacological treatment.
Outcome
evidence
Reduced rate of transition to full psychosis and
reduced duration of untreated psychosis for those who
do develop it.
Economic Reduction in inpatient costs and lost employment,
pay-offs
reduction in homicide rate, reduction in suicide rate.
Findings
In short-term (Year 1) there is a net cost, but the total
return on £1 investment over a 10-year period is
£10.27 – 26% of this is to the NHS

Costeffectiveness

If the core clinical/care question is:
‘Does this intervention work?’
Then the economic question is:
‘Is it worth it?’

Trade-offs … is it worth it?
If an intervention is more effective and also more costly, then
calculate the cost per unit gain in effectiveness. Crunch
question: Is it worth it?
So we could:

Attach a monetary value to the outcome gain

Show decision-maker the cost-effectiveness of various
ways to spend their money and get them to choose

Show decision-maker the probability of costeffectiveness at different WTP values

… or ask them how much they are willing to pay?

Set a threshold, rigidly or as a guide (cf. NICE) …

… But then need a way to compare across different
diagnostic groups) … and hence use of QALYs, DALYs

Example
Computerised Cognitive Behavioural
Therapy (CBT) for anxiety and
depression
Design n=274 primary care patients (aged
18-75) with depression and/or anxiety
disorder; not currently receiving face-toface psychological therapy. RCT
Interventions ‘Beating the Blues’ (BtB) – 8
sessions (50 mins each) of therapy on top
of usual care vs. treatment as usual
(TAU) alone (discussions with GP, referral
to counsellor, practice nurse or MH
professional, etc)
Aim To compare effectiveness and costeffectiveness of BtB and TAU
Proudfoot et al, Brit J Psychiatry 2004; McCrone et al, Brit J Psychiatry, 2004
Beating the Blues: results
Effectiveness
 BtB better than treatment as usual on clinical
measures of symptoms (Beck Depression Inventory,
Beck Anxiety Inventory) and functioning (Work and
Social Adjustment Schedule)
Cost
 BtB more costly than standard care (to NHS)
So is it worth it?
 Cost per 1 incremental gain on Beck Depression
Inventory = £21
 Cost per additional depression-free day = £2.50
 Cost per additional QALY = £2190
Proudfoot et al, Brit J Psychiatry 2004; McCrone et al, Brit J Psychiatry, 2004
Incentives
Using economic incentives
Providing information about what people do and the
associated economic consequences
Rewarding/penalising decision-makers for ‘good/bad
decisions’ or good/bad performance
Hence:
o
Fee for service … the GP contract
o
Payment by results (HRGs)
o
Incentive-based contracts / salaries
o
Provider competition within health / social care
o
Financial rewards for patients (e.g. FIAT)
