title: Initiation of oral contraceptives using a quick start compared with a conventional start: a randomized controlled trial.
abstract: OBJECTIVE
  To estimate whether young women taking the first pill on the day of prescription had higher continuation rates and lower pregnancy rates than women who waited until menses to start the oral contraceptive pill (OCP).
  
  
  METHODS
  We recruited 1,716 women aged younger than 25 years seeking to initiate the oral contraceptive at three publicly funded family planning clinics, and randomly assigned them to conventional initiation of the pill (conventional start) or immediate, directly observed ingestion of the first pill (quick start) during the clinic visit. Women underwent follow-up interviews at 3 and 6 months.
  
  
  RESULTS
  Sixty percent of participants discontinued the pill, and 8% became pregnant during follow-up. Women who took the first pill in the clinic were more likely to continue to the second OCP pack (odds ratio 1.5, 95% confidence interval 1.0-2.1.); however, the Quick Start approach did not improve OCP continuation rates at 3 and 6 months. Those assigned to Quick Start were slightly less likely to become pregnant within 6 months from the time they started the pill (hazard ratio 0.90, 95% confidence interval 0.64-1.25). Eighty-one percent of women rated the Quick Start approach as acceptable or preferable to waiting. Rates of serious adverse events were low and similar in the two groups.
  
  
  CONCLUSIONS
  Protocols that require a woman to wait until the next menses to start hormonal contraceptives are an obstacle to contraceptive initiation. Directly observed, immediate initiation of the pill improves short-term continuation.
