Impact of a policy change restricting access to codeine on prescription opioid-related emergency department presentations: an interrupted time series analysis.

Codeine is one of the most commonly used opioid analgesics. Significant codeine-related morbidity and mortality prompted regulatory responses, with the up-scheduling of codeine combination analgesics to prescription-only medicines implemented in Australia in February 2018. This study investigated the impact of codeine up-scheduling on the number of codeine and other (noncodeine) prescription opioid-related emergency department (ED) presentations in a large metropolitan tertiary hospital.

Impact of a new specialist alcohol and drug brief intervention service model integrated into the emergency department: An interrupted time series analysis.

Objective: To describe and examine the impact of a new specialist drug and alcohol brief intervention team (DABIT) model integrated into the ED on the identification of individuals at risk of future alcohol and other drug (AOD)-related harm. A cost-outcome analysis was conducted to assess the impact on costs per referral.

Methods: An interrupted time series analysis examined the changes in number of referrals following the implementation of the DABIT model over 2 years (January 2015-December 2016) within a large 436-bed public hospital.
