Patient choice of adjunctive nonpharmacologic pain management during first-trimester abortion: a randomized controlled trial.

OBJECTIVE

To determine if offering patients a choice of adjunctive nonpharmacologic pain management during first-trimester aspiration abortion results in lower pain scores when compared with standard care.

STUDY DESIGN

We enrolled women receiving first-trimester aspiration abortion at the University of Hawaii. We randomized patients to standard care (control) or standard care plus a choice of nonpharmacologic pain management options (intervention). Standard care was ibuprofen 800 mg orally at least 30 min preprocedure, lidocaine paracervical block and anticipatory guidance from the provider. We measured pain on a 100-mm visual analog scale immediately postprocedure with adequate sample size to detect a 20-mm difference in pain scores.

RESULTS

Seventy-four women participated in the trial and reported an overall mean pain score of 61.9±27.0. Participants in the control and intervention groups reported similar overall mean pain scores (control 60.6±28.8, intervention 63.3±28.5). We found procedure time, complications, provider-perceived case difficulty and patient satisfaction with pain management to be similar between groups. Providers underestimated participant pain compared to participants' own scores (mean physician estimate of participant pain: 46.3±18.5, mean participant pain score: 61.9±27.0, p<.01). Intervention group participants most frequently selected ambient music (59%) as the nonpharmacologic intervention. Forty-one percent (15/37) of participants in the intervention group chose more than one nonpharmacologic intervention.

CONCLUSIONS

Participants in the control group reported similar pain scores to participants in the intervention group. Procedure time and difficulty were similar between the two groups.

IMPLICATIONS

Incorporating patient choice into a nonpharmacologic pain management model did not result in lower pain scores. This approach did increase the patient's visit time. Abortion providers frequently use nonpharmacologic pain management in the United States, and these techniques did not negatively impact patient pain scores in our study.
