Reducing the Number of Opioids Consumed After Discharge Following Elective Cesarean Delivery: A Randomized Controlled Trial.

OBJECTIVE: To reduce opioids consumed after discharge from hospital after elective cesarean delivery by 50%.

METHODS: This was a two-week parallel group non-blinded randomized controlled trial at Mount Sinai Hospital. Eligible women undergoing elective cesarean delivery were assigned by random number generation to receive the hospital's standard post-cesarean opioid prescription of 20 1-mg hydromorphone tablets or a prescription for 10 1-mg hydromorphone tablets if opioids were required in hospital or no hydromorphone if no opioids were required in hospital. Patients completed a study questionnaire at two weeks postpartum detailing outcome measures. The primary outcome was the amount of opioid consumed after discharge.

RESULTS: A total of 40 women were randomly assigned to a study group and 37 were included in the data analysis; 17 patients were in the control group and 20 in the experimental group. The median number of tablets consumed did not differ between groups (P = 0.407). The median number of excess tablets prescribed was 20 (range 2-18) in the control group and 0 (range 0-10) in the experimental group (P < 0.001).

CONCLUSIONS: The current standard discharge practice of giving 20 1-mg hydromorphone tablets to all patients post-discharge after cesarean delivery contributes to a substantial excess of opioids in the community. These opioids can be diverted for unintended or accidental usage, and exacerbate larger societal issues of opioid misuse and addiction. Decreasing the number of opioids prescribed with tailored discharge prescriptions based on in-hospital opioid use provides nearly all patients with adequate pain control.
