Estimating long-term trends in the incidence and prevalence of opiates use/injecting drug use and the number of former users : back-calculation. Methods and opiate overdose deaths

D. DE ANGELIS ; M. HICKMAN ; S. YANG | 2004
Dans American Journal of Epidemiology (Vol.160, n°10, November 15, 2004) Article : Périodique

The authors explored an age-specific back-calculation approach to estimating long-term trends in the incidence and prevalence of opiate use/injecting drug use (IDU) in England for 1968-2000. The incidence of opiate use/IDU was estimated by combi[...]

Estimating the relative incidence of heroin use: application of a method for adjusting observed reports of first visits to specialized drug treatment agencies

M. HICKMAN ; SEAMAN S. ; D. DE ANGELIS | 2001
Dans American Journal of Epidemiology (Vol.153, n°7, April 2001) Article : Périodique

In this paper, the authors propose a method for estimating the incidence of heroin use by adjusting reported numbers of heroin users visiting drug treatment agencies for the time lag between onset of heroin use and first treatment request (lag d[...]

Multiple parameter evidence synthesis - a potential solution for when information on drug use and harm is in conflict [Editorial]

M. HICKMAN ; D. DE ANGELIS ; H. JONES ; R. J. HARRIS ; N. WELTON ; A. E. ADES | 2013
Dans Addiction (Vol.108, n°9, September 2013) Article : Périodique

The quality of the evidence on estimating drug-related harm is not yet as advanced as that for intervention effectiveness. Multiple parameter evidence synthesis offers a potential solution, in which 'all available evidence' is combined into a si[...]
