The burden and costs of chronic diseases in low-income and middle-income countries.

This paper estimates the disease burden and loss of economic output associated with chronic diseases-mainly cardiovascular diseases, cancer, chronic respiratory diseases, and diabetes-in 23 selected countries which account for around 80% of the total burden of chronic disease mortality in developing countries. In these 23 selected low-income and middle-income countries, chronic diseases were responsible for 50% of the total disease burden in 2005. For 15 of the selected countries where death registration data are available, the estimated age-standardised death rates for chronic diseases in 2005 were 54% higher for men and 86% higher for women than those for men and women in high-income countries. If nothing is done to reduce the risk of chronic diseases, an estimated US$84 billion of economic production will be lost from heart disease, stroke, and diabetes alone in these 23 countries between 2006 and 2015. Achievement of a global goal for chronic disease prevention and control-an additional 2% yearly reduction in chronic disease death rates over the next 10 years-would avert 24 million deaths in these countries, and would save an estimated $8 billion, which is almost 10% of the projected loss in national income over the next 10 years.

Can non-physician health-care workers assess and manage cardiovascular risk in primary care?

OBJECTIVE: To ascertain the reliability of applying the WHO Cardiovascular Risk Management Package by non-physician health-care workers (NPHWs) in typical primary health-care settings. METHODS: Based on an a priori 80% agreement level between the NPHWs and the "expert" physicians (gold standard), 649 paired (matched) applications of the protocol were obtained for analysis using Kappa statistic and multivariate logit regression. FINDINGS: Results indicate over 80% agreement between raters, from moderate to perfect levels of agreement in almost all of the sections in the package. The odds of obtaining a difference between raters and a benchmark are not statistically significant. CONCLUSION: Applying the WHO Cardiovascular Risk Management Package, NPHWs can be retrained to reliably and effectively assess and manage cardiovascular risks in primary health-care settings where there are no attending physicians. The package could be a useful tool for scaling up the management of cardiovascular diseases in primary health care.
