In this blog we consider recent literature (particularly reviews) on the effectiveness and cost-effectiveness of dietary counselling as a health intervention. Most studies suggest that dietary counselling is effective though the benefits are typically modest and short-term. The literature on cost-effectiveness is mixed, and there is substantial uncertainty about long-run cost-effectiveness given the typically short-term trials involved. Addressing the obesogenic environment will have potentially (much) larger gains, and due to substantial reductions in obesity-related disease it is likely to be cost-saving. However, governments, policy-makers and the public are often interested in counselling interventions, necessitating close attention to cost-effectiveness of these interventions relative to more structural changes to the environment.

We have just published a modelling study on exercise programmes in NZ to prevent falls in older people. This work suggests that this approach (home-based or group-based exercise) is good value for money for the NZ Government. In this blog we consider these results alongside other fall prevention interventions that policy-makers can consider – which are now all in the BODE3 online interactive league table.

In this fourth blog that features the BODE3 Interactive League Table, we look at substantive findings across the interventions (so far) in the league table.  We use graphs from the league table to cautiously explore (for fear of over-generalizing) what approaches might typically generate the most health gain and be best value-for-money.

Last week we introduced the concept of league tables to compare interventions.  This week we provide a brief ‘user guide’ for our just launched BODE3 Interactive League Table.  We walk through how to pull down tables and graphs of health gain (quality-adjusted life-years; QALYs), health system costs and cost effectiveness for 50+ interventions currently in the interactive league table.

NZ’s Quitline Service is value-for-money: But how does it compare with other tobacco control actions in a league table?

We have just published a journal article on the cost-effectiveness of NZ’s Quitline service (including its associated promotion in the mass media). The study found that this intervention package is likely to be an effective means to generate health gain, address health inequalities and save costs for the NZ health system. But in this blog we also compare the New Zealand Quitline intervention with other tobacco interventions using our just launched BODE3 Interactive League Table, and find that whilst the Quitline is a good thing to do, much more health gain is possible through other tobacco control interventions.
