This paper examines the applicability of the diffusion model to drug use. A variety of studies that employ the diffusion model to examine drug-related behaviour, including the use of alcohol, tobacco and illicit drugs, are discussed. Studies include those that focus on "natural" or spontaneous diffusion and those in which diffusion of a drug or a drug-related intervention is planned. Most studies examined support the application of the diffusion model in the study of drug use. The model is particularly valuable when new substances are introduced to a population or subgroup. The addition of economic and other forms of availability as a determinant of adoption would increase the power of the model. Recommended directions for research are outlined. The diffusion model has been used successfully in the study of drug use for several decades. More rigorous designs would strengthen this type of research and provide direction for policymakers and those involved in public health and education.
OBJECTIVE: To elucidate the real impact in the medical literature of the different denominations for reflex sympathetic dystrophy (RSD). METHODS: A search was performed through the Medline database (WinSPIRS, SilverPlatter International, NS), from 1995 to 1999, including the following descriptors: RSD, complex regional pain syndrome (CRPS), CRPS type I, algodystrophy, Sudeck, shoulder-hand syndrome, transient osteoporosis, causalgia, and CRPS type II. RESULTS: The descriptor RSD was detected in 576 references, algodystrophy in 54, transient osteoporosis in 42, CRPS type I in 24, Sudeck in 16, and shoulder-hand syndrome in 11. One hundred records were obtained for the descriptor causalgia and five for CRPS type II. The descriptor RSD was detected in the title of 262 references, algodystrophy in 29, transient osteoporosis in 29, CRPS type I in 15, Sudeck in 3, shoulder-hand syndrome in 5, causalgia in 17, and CRPS type II in 3 references. CONCLUSIONS: The new CRPS terminology has not effectively replaced the old one. RSD and causalgia are the most used denominations.
