AIM: To evaluate costs and health outcomes of nalmefene plus psychosocial support, compared with psychosocial intervention alone, for reducing alcohol consumption in alcohol-dependent patients, specifically focusing on societal costs related to productivity losses and crime., METHODS: A Markov model was constructed to model costs and health outcomes of the treatments over 5 years. Analyses were conducted for nalmefene's licensed population: adults with both alcohol dependence and high or very high drinking-risk levels (DRLs) who do not require immediate detoxification and who have high or very high DRLs after initial assessment. The main outcome measure was cost per quality-adjusted life-year (QALY) gained as assessed from a UK societal perspective. Alcohol-attributable productivity loss, crime and health events occurring at different levels of alcohol consumption were taken from published risk-relation studies. Health-related and societal costs were drawn from public data and the literature. Data on the treatment effect, as well as baseline characteristics of the modelled population and utilities, came from three pivotal phase 3 trials of nalmefene., RESULTS: Nalmefene plus psychosocial support was dominant compared with psychosocial intervention alone, resulting in QALYs gained and reduced societal costs. Sensitivity analyses showed that this conclusion was robust. Nalmefene plus psychosocial support led to per-patient reduced costs of 3324 and 2483, due to reduced productivity losses and crime events, respectively., CONCLUSION: Nalmefene is cost effective from a UK societal perspective, resulting in greater QALY gains and lower costs compared with psychosocial support alone. Nalmefene demonstrates considerable public benefits by reducing alcohol-attributable productivity losses and crime events in adults with both alcohol dependence and high or very high DRLs who do not require immediate detoxification and who have high or very high DRLs after initial assessment.
