Educational outreach as well as audit and feedback continue to dominate research into prescribing interventions. These 2 prescribing interventions also most consistently show positive results. Much less research is conducted into other types of interventions and there is still very little effort to systematically test why interventions do or do not work.

The over-use of antibiotics, in particular, inappropriate use to treat upper respiratory tract infections (URTIs), is a global public health concern. In an attempt to reduce inappropriate use of antibiotics for URTIs, and, in particular, to modify patient misconceptions about the effectiveness of antibiotics for URTIs, Australia's National Prescribing Service Ltd (NPS) has undertaken a comprehensive, multistrategic programme for health professionals and the community. Targeted strategies for the community, via the NPS common colds community campaign, commenced in 2000 and have been repeated annually during the winter months. Community strategies were closely integrated, using the same tagline, key messages and visual images, and were delivered in numerous settings including general practice, community pharmacy, child-care centres and community groups. Strategies included written information via newsletters and brochures, mass media activity using billboards, television, radio and magazines and small grants to promote local community education. The evaluation used multiple methods and data sources to measure process, impact and outcomes. Consistent with intervention messages, the integrated nationwide prescriber and consumer programme is associated with modest but consistent positive changes in consumer awareness, beliefs, attitudes and behaviour to the appropriate use of antibiotics for URTIs. These positive changes among the community are corroborated by a national decline in total antibiotic prescriptions dispensed in the community (from 23.08 million prescriptions in 1998-99 to 21.44 million in 2001-02) and, specifically, by a decline among the nine antibiotics commonly used for URTI such that by 2003 nationally 216,000 fewer prescriptions for URTI are written each year by general practitioners.

Medicines make an essential contribution to the health of the community, but rapidly rising drug budgets have caused governments to seek ways of ensuring this expenditure results in value for money. The National Prescribing Service was established against this background to implement a quality use of medicines service as par t of the National Medicines Policy. A range of programmes that attempt to use evidencebased strategies to deliver evidence-based messages have been established. These use multifaceted interventions, such as newsletters, prescriber feedback, clinical audit and educational visiting, that are provided both centrally, through the national office, and locally, through Divisions of General Practice. The work is underpinned by an evaluation strategy that incorporates strong qualitative elements as well as an emphasis on time-series analyses for changes in drug utilization. Some 80% of Australian general practitioners have voluntarily participated in activities such as educational visiting and clinical audit within the National Prescribing Service prog rammes. New programmes for the community and consumers will be coordinated with the work that has become well established within general practice.

A national education program aimed at GPs was successful in improving prescribing for hypertension. Lessons learned will be applied in evaluation of future NPS programs and are also applicable to analysis of other interventions aimed at influencing prescribing behaviour.

Background and aims Opioid agonist treatment is effective but resource intensive to administer safely in custodial settings, leading to significant under‐treatment of opioid dependence in these settings world‐wide. This study assessed the safety of subcutaneous slow‐release depot buprenorphine in custody. Design Open‐label, non‐randomized trial. Setting Correctional centres in New South Wales, Australia. Participants Sixty‐seven men and women, aged ≥ 18 years of various security classifications with a diagnosis of moderate to severe DSM‐5 opioid use disorder currently serving a custodial sentence of ≥ 6 months were recruited between November 2018 and July 2019. Patients not in opioid agonist treatment at recruitment commenced depot buprenorphine; patients already stable on oral methadone treatment were recruited to the comparison arm. Intervention and comparator Depot buprenorphine (CAM2038 weekly for 4 weeks then monthly) and daily oral methadone. Measurements Safety was assessed by adverse event (AE) monitoring and physical examinations at every visit. Participants were administered a survey assessing self‐reported diversion and substance use at baseline and weeks 4 and 16. Findings Retention in depot buprenorphine treatment was 92.3%. Ninety‐four per cent of patients reported at least one adverse event, typically mild and transient. No diversion was identified. The prevalence of self‐reported non‐prescribed opioid use among depot buprenorphine patients decreased significantly between baseline (97%) and week 16 (12%, odds ratio = 0.0035, 95% confidence interval = 0.0007–0.018, P < 0.0001). Conclusions This first study of depot buprenorphine in custodial settings showed treatment retention and outcomes comparable to those observed in community settings and for other opioid agonist treatment used in custodial settings, without increased risk of diversion.
