| Parents' Postoperative Pain Measure (PPPM) Scores | 48 hours postoperatively | 15-item, yes/no behavioral checklist based on non-verbal pain cues children show following surgery. Scale is from 0 to 15, with higher scores denoting more severe pain. A score of 6+ has been validated as a threshold for a child experiencing clinically significant pain. |

Outcome results
Parents' Postoperative Pain Measure (PPPM) Scores
15-item, yes/no behavioral checklist based on non-verbal pain cues children show following surgery. Scale is from 0 to 15, with higher scores denoting more severe pain. A score of 6+ has been validated as a threshold for a child experiencing clinically significant pain.
Time frame: 10-14 days postoperatively
Population: Two patients in the intervention arm were lost to follow-up at the 10-14d followup (thus 50 were available for analysis)
