Effectiveness, safety and acceptability of self-assessment of the outcome of first-trimester medical abortion: a systematic review and meta-analysis.

BACKGROUND: For many women, the need for multiple clinical visits is a barrier to medical abortion.

OBJECTIVES: We assessed the effectiveness, safety, and acceptability of self-assessment of the outcome of medical abortion completed at home versus routine clinic follow up after medical abortion.

SEARCH STRATEGY: We searched databases such as MEDLINE, Embase, and CENTRAL to find studies published in 1991-2018.

SELECTION CRITERIA: Eligible studies included women of reproductive age who had undergone a medical abortion that was completed at home. The intervention and self-assessment of the outcome of medical abortion done by urine pregnancy tests kits by women at home was compared with routine medical follow up at a clinic.

DATA COLLECTION AND ANALYSIS: Two researchers completed the study selection, data extraction, critical appraisal, and assessment of the evidence. The outcomes were successful complete abortions, side effects and complications, and acceptability. We performed meta-analyses when possible and GRADE to ascertain the certainty of the evidence. The protocol was registered in PROSPERO (CRD42017055316).

MAIN RESULTS: Four randomised controlled trials (RCTs; n = 5493) met our inclusion criteria. The pooled analysis from all studies showed no significant difference in complete abortion rates between self-assessment and routine clinic follow up: RR = 1.00, 95% CI 0.99-1.01. The ongoing pregnancy rates were similar and the pooled results for the safety outcomes showed no significant differences between the groups. There was a significantly greater preference for self-assessment as the follow-up method.

CONCLUSIONS: The effectiveness, safety, and acceptability of self-assessment of the outcome of medical abortion completed at home are not inferior to routine clinic follow up.

TWEETABLE ABSTRACT: The effectiveness, safety, and acceptability of self-assessment of the outcome of medical abortion are not inferior to routine clinic follow up.
