The certainty of evidence is downgraded by inconsistency across studies.
A Cochrane review [Abstract] 1 included 3 studies with a total of 1162 subjects. Unintended pregnancy within 6 months after abortion was lower with immediate insertion compared with delayed insertion (RR 0.25, 95% CI 0.08 to 0.77; 3 RCTs, n=1029). Immediate insertion of contraceptive implants improved the initiation rate compared to delayed insertion (RR 1.26 for medical abortion, 95% CI 1.21 to 1.32; 2 RCTs, n=1014 and RR 2.32 for surgical abortion, 95% CI 1.79 to 3.01; 1 RCT, n=148). There was no difference in failure of medical abortion between immediate or delayed insertion.
