Medically Supervised Injection Centres (MSICs) are legally-sanctioned facilities where users can consume pre-obtained drugs under medical supervision. Although there is a substantial body of research exploring their effectiveness, there have been few attempts to quantify outcomes across studies. In order to determine the impact of the body of research as a whole, outcomes from studies were synthesised using meta-analysis.
Literature sources were identified through searches in four bibliographic databases. Inclusion in the final review was dependent on the study meeting certain eligibility criteria, including a minimum of pre-test, post-test, control group designs. Data were extracted and pooled in a meta-analysis using both fixed and random effects methods.
Eight studies met the inclusion criteria. Overall, MSICs had a significant, but small, positive effect on outcomes based on the fixed effect analysis and no effect based on random effect analysis. The results of the independent outcome analyses showed that MSICs had a significant favourable result in relation to drug-related crime and a significant unfavourable result in relation to problematic heroin use or injection. MSICs were found to have no effect on overdose mortality or syringe/equipment sharing.
Whilst the effectiveness of the early versions of MSICs remains uncertain, this should not rule out continuing to test and develop MSICs in locations where public injecting and other drug-related harms are a major problem. It is important, however, that evaluation research publishes replicable data to enable future meta-analyses and to expand the body of knowledge in the field.

Last week Scotland’s leading law officer, the Lord Advocate, brought a shuddering halt to a proposal from Glasgow City Council to develop a safe injecting centre in the city. Such a centre would have required a change in UK drug laws to enable individuals in possession of illegal drugs to use those drugs within the centre without fear of prosecution. Supporters of this initiative will be disappointed by the outcome, but they need to recognise that the provision of some level of legal protection covering the possession of illegal drugs within the injecting centre would also, by implication, need to be extended to all of those who might claim, legitimately or otherwise, that their drug possession should be green-lighted because they were en route to the injecting centre. In effect, such an initiative would deliver what many of its supporters actually desire – the legalisation of illegal drugs within at least some part of the UK.
In his judgement, the Lord Advocate has not ruled against setting up a centre where doctors can prescribe opiate drugs to addicts. Rather he has simply pointed out that he is not prepared to offer legal protection to a centre where illegal drugs are being used. The Glasgow proposal sought unwisely to tie the proposal for a doctor-led heroin prescribing clinic, which would be legal, with a setting where individuals are allowed to use illegal drugs which would break UK drug laws. There will be many who rightly question the wisdom (and the cost to the public purse) of linking those two proposals.
