Lancet chronic disease series
This series of five articles outlines new challenges and unsolved problems since the journal's last series in 2005. The first article ([189kB]) predicts the disease burden and economic losses that developing countries would face from chronic diseases such as cardiovascular disease, cancer, chronic respiratory disease, and diabetes. In the 23 countries that the authors incorporated into a model, chronic disease was responsible for 50% of the disease burden in 2005. If no action is taken, they say, about US$84 billion of economic production will be lost from heart disease, stroke, and diabetes alone in these 23 countries between 2006 and 2015. The second article ([105kB]) looks at how to scale-up strategies to fight chronic diseases in developing countries. The authors review evidence to identify which methods are cost-effective and financially feasible, and therefore ready to be scaled-up.
Tobacco control, salt reduction (both of which are detailed in the series' third paper ([177kB])), and a multidrug strategy to treat individuals with high-risk cardiovascular disease (see an in-depth look in paper four ([220kB])) are prime candidates for scaling-up. What effect improving health systems has on the level of chronic diseases should be properly evaluated, say the authors. For some health interventions, such as preventing or controlling diabetes, there is little cost-effectiveness data for low or middle-income countries, but their scientific effectiveness is so compelling that countries should consider how best to incorporate them. The final paper ([92kB]) is a call to action to incorporate existing interventions into healthcare programmes, which in 2005 was costed at US$5.8 billion.
