The Global Burden of Disease 2007
The original Global Burden of Disease Study was commissioned by the World Bank in 1991 to provide a comprehensive assessment of the burden of 107 diseases and injuries and ten selected risk factors for the world in 1990. The methods of the original GBD This study created the means to define loss of health associated with disease morbidity and mortality. In addition to providing figures on disease mortality, prevalence and incidence across the world regions it also recorded two measures of disability The disability-adjusted life year (DALY) , a measure that combined years of life lost due to premature mortality and years of life lived with disability due to time lived in unhealthy states (YLDs ).
The current GBD survey was different to its predecessors in that for each cluster of disease a team of experts was recruited to provide data for the years being surveyed 1990 and 2005 for incidence and prevalence as well as defining measures for disability. For the first time a dermatology group was convened to generate and analyse the data which was then completed by the Institute of Health Metrics in Seattle Washington. Participating Universities included the Institute of Health Metrics, University of Washington, the Johns Hopkins University, the Harvard School of Public Health, the University of Queensland and the World Health Organisation.
Given the complexity and number of skin conditions the dermatology team divided the subject into eczema, psoriasis, and examples of infectious skin disease (cutaneous fungal infections, cutaneous bacterial infections, viral warts, scabies) and non-infectious skin disease (pruritus, urticaria, acne vulgaris, alopecia) and non-melanoma skin cancer. Melanoma and also other infections such as herpes simplex and zoster were recorded with infectious diseases. Problems encountered by the team included a sparcity of robust published data divided into appropriate subcategories, the use of disability measures in this study as opposed to quality of life scales and the general lack of large data bases that record skin disease.
WHO – Model lists for Essential Medicines
The World Health Organisation provides guidance, using evidence-based criteria, for those medications that are considered essential or critically important to the maintenance of health. These are divided into two categories: Essential Medicines for Adults and Essential Medicines for Children. The ILDS has provided advice on the inclusion and exclusion of drugs. As a participant in this exercise the views of the League are only one of a series of expert views that are used to develop the final list. The list is revised every two years and the ILDS through a team of dermatologists with special interests also provides answers to queries about medications for dermatological use raised by the WHO Expert Advisory committee
