Planning postpartum contraception for women with substance use disorders: Utilisation of the birth admission

Women with substance use disorders (SUD) use less contraception, and experience higher rates of unintended pregnancy, compared to women without SUD. Contraception is discussed at the six-week postnatal appointment, which many women with SUD do not attend. Therefore, it is important women have the opportunity to formulate contraception plans before discharge from the birth admission.

To assess postpartum contraception plans, including initiation and method of interest, among women with SUD and compare these to women without SUD.

All births from January 2011 to September 2019 from one New South Wales local health district were analysed. Data included maternal demographics, SUD, and contraception plans. Chi-squared statistics and multivariate multinomial regression analyses were used to compare outcomes for women with and without SUD.

Of 59 195 mothers, 429 (0.7%) had a SUD. There were 50.1% of women with SUD and 56.2% without SUD (P = 0.03) who had no documented plan for contraception. There were 37.3% of women with SUD and 42.4% without SUD (P = 0.06) who had a prescription for contraception or a referral to discuss contraception. There were 12.5% of women with SUD and 1.4% without SUD (P < 0.001) who initiated contraception in hospital.

Although postpartum contraception initiation was higher among women with SUD, half of all women (with or without SUD) were discharged without a plan for contraception initiation. Embedding provision of postpartum contraception into maternity care, or investigating other opportunities, may improve access for all women, including those with SUD.
