What do economists mean by cost effectiveness?
Economics is about choice
Budget
Choice ‘A’Choice ‘B’
Resources are always constrained;
How can we best spend public monies to maximise benefit to society
Be mindful of potential consequences for fairness and equity
Economic evaluation
The effectiveness question:
Does this intervention work?
The economic question:Is it worth it?
Two Basic Needs: (A) Costs and Outcomes; (B) 2+ Alternatives
Outcomes (e.g. Quality of Life Years (QALYs) for intervention X
Costs for intervention X
Costs for intervention Z Outcomes (e.g
Quality of Life Years (QALYs) for intervention Z
Cost per QALY circa £30,000 considered good value; But need to be mindful of budgetary impact
Medically Unexplained Symptoms:Impacts on NHS in England
• 22% of all primary care consultations • 7% of all prescriptions• 25% of all outpatient care• 8% of all inpatient bed days• 5% of A & E attendances

Economic Modelling study Objective: To evaluate the cost effectiveness of detection in
primary care followed by cognitive behavioural therapy for sub- threshold and somatoform disorders
Outcomes: Improvement in Quality of Life Scores over 3 yearsImpact on employment rates over 3 years
Impacts on use of NHS resources over 3 years
Data: Cost data from NHS sources, Bermingham study; Cost of awareness training for GPs (including need for locums) from national sources; E-learning for GPs as alternative; IAPT cost data for CBT costs. Incidence of MUS from Bermingham study

Implications
Potentially cost effective / cost saving to NHS for severe somatoform disorder
Need to look at case for stepped care approach Examine lower cost interventions initially for sub-
threshold Consider impact on costs, effectiveness and uptake
of computerised CBT Conservative analysis Potential impacts on other family members Other service user groups that benefit from
investment in infrastructure for psychological therapies
Impact of co-morbid depression and diabetes in Great Britain
Using data from Psychiatric Morbidity Survey, compared to people with diabetes alone:
Four times more likely to have difficulty in managing medical care
Twice as likely to have consulted primary care doctor about physical health in previous year
Six times more likely to have days off from work
Four times more likely to report other impacts on work/regular activities

Usual care Care management
Katon et al, Diabetes Care, 2008
Compared usual primary care and a nurse depression intervention (12 months - education, behaviour activation, choice between medication and problem-solving therapy)
Requires better early recognition of co-morbidity
Potential economic benefits of collaborative care in England
2 year economic model using effectiveness data from literature review
Estimated the costs and benefits of investing in GP nurse case- manager led collaborative care following screening for depression in cases of diabetes Type II
Cost per QALY gained £3600
But significant additional initial costs to run programme
But long term substantial costs of diabetes complications avoided not included
King, Moloswanke & McDaid 2011
Obtaining Health Economic Inputs
• More challenging to obtain health economic input? More limited role of NICE on economic impact
• Potential inefficiencies in having multiple GP clusters all looking for health economic inputs
• Pooling resources – to look at economic issues?• Making use of continuing resources e.g. NICE
systematic reviews? York Economic Database• But need for even more local consideration of
budgetary issues• Local Health Economies: relationship with local
authority public health groups?
Implications for GP commissioning
• GP Commissioning could provide opportunities for local innovation and clinician led care
• Could better meet local mental health needs
• But speed of change / administrative impact potential challenging
• Safeguarding resources for primary care elements of mental health strategy?
• ‘Buy In’ from sectors that benefit from better mental health may be even more challenging with more devolution of budget holding:
To sum up• The personal, health, social and economic costs of
poor mental health in England are substantial• Opportunities for scaling up of cost effective
services at primary care level, e.g. tackling risk of co-morbidities; appropriate use of psychological therapies – building on IAPT capacity
• But local choice will need to more variation in service provision – not always helpful
• Potential challenges in obtaining budgetary and economic inputs for decision making in more fragmented system?
