Abstract
Issues. Despite the potential advantages of community detoxification for alcohol dependence, in many countries the available
resources are mostly focused on specialist services that are resource-intensive, and often difficult to access because of financial or
geographical factors. The aim of this systematic review is to synthesise the existing literature about the management of alcohol
detoxification in the community to examine its effectiveness, safety, acceptability and feasibility. Approach. The systematic
review was guided by an a priori defined protocol consistent with the PRISMA (Preferred Reporting Items for Systematic Re-
views and Meta-Analyses) statement. Cochrane library, Medline, EMBASE, PsycINFO, Global Health and CINAHL da-
tabases were searched using appropriate search terms. A qualitative synthesis of the data was conducted as the heterogeneity of
study designs, samples and outcomes measured precluded a meta-analyses. Key Findings. Twenty studies with a range of de-
signs were eligible for the review. Community detoxification had high completion rates and was reported to be safe. Compared to
patients undergoing facility based detoxification, those who underwent community detoxification had better drinking outcomes.
Community detoxification was cheaper than facility based detoxification and generally had good acceptability by various stake-
holders. Implications. For certain patients, community detoxification should be considered as a viable option to increase ac-
cess to care. Conclusions. Although the current evidence base to some extent supports the case for community detoxification
there is a need for more randomised controlled trials testing the cost effectiveness of community detoxification in comparison with
inpatient detoxification. [Nadkarni A, Endsley P, Bhatia U, Fuhr DC, Noorani A, Naik A, Murthy P, Velleman R.
