Aims: To assess change in clinicians’ knowledge for managing an opioid overdose and administering naloxone following training, evaluate whether the ‘cascade method’ is efficient for disseminating training, and evaluate the barriers to implementing training.

Design: Repeated measures design evaluated knowledge pre-and-post training. Follow-up for one year to assess the cascade method. Sample of clinicians followed up to assess barriers to implementing training.

Setting: Initial training in London cascaded to 6 addictions services across England.

Participants: Healthcare professionals in Addictions services.

Intervention: Two-hour interactive training session on overdose management and naloxone administration. Trained clinicians were expected to train other clinicians/clients.

Measurements: Self administered structured questionnaire recording overdose knowledge and confidence pre-and-post training and barriers to implementation of training.

Findings: 219 clinicians trained with a mean composite score of 18.3 (±3.8) for opioid overdose risks, signs and actions to be taken following an overdose out of a possible 26 and after training demonstrated a significant increase in knowledge increasing to 21.2 (±4.1) (Z=9.2, P<0.001). Confidence and willingness to administer naloxone improved (p<0.05). One hundred clinicians trained a further 119 clinicians (n=219) and ‘trained’ clinicians (N=219) trained a further 239 drug users. Motivation, resources, treatment philosophy and confidence, were barriers to implementing training.

Conclusions: Training healthcare workers in addictions on how to manage an opioid overdose and administer naloxone improved knowledge and was considered effective. The ‘cascade method’ was not successful for disseminating the training to large numbers of clinicians or drug users which may be related to clinician and service related barriers.
