Women who attend alcohol and other drug (AOD) services experience higher rates of unintended pregnancy, and access less contraception, than the general population. This study aims to observe contraceptive initiation and use after contraception services were offered at metropolitan and regional AOD services. Clinical staff were provided contraception education. One hundred women aged 16-49 were recruited from two services between 2017 and 2021. Women completed a questionnaire on their obstetrics and gynaecological history, pregnancy plans and contraception use. Women were provided education on contraception options and offered referral to a contraception pathway. The primary outcome was initiation of highly reliable contraception; secondary outcomes were the types of contraception initiated, and contraception use and pregnancy at 12 months. We compared the initiation of contraception across the two study sites. At baseline, 91% of women were not planning a pregnancy within 12 months, with 21% of these using highly reliable contraception. Of all women not planning a pregnancy, 28% initiated highly reliable contraception via the pathway (2% metropolitan, 51% regional, p < 0.001), with intrauterine devices being the most frequent method initiated (15%). At 12 months, 44% were using highly reliable contraception and 15% had recorded pregnancies. Contraception pathways for women in AOD treatment can improve initiation of highly reliable methods of contraception, although pregnancy rates were still high and there were large differences between the study sites. Care navigation and clinical champions are some potential facilitators to contraception access, and understanding additional barriers to access may be useful.
