Different ways to record pain after surgery.

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized interventional study compares three methods of collecting postoperative pain intensity using a time- and date-stamped 0–10 visual analogue scale: a hand-written pain journal, a smartphone app, and a novel electronic pain recorder. Adult patients are randomly assigned to one of the three arms and instructed to record their pain as often as they like during the postoperative period. The primary outcome is the number of pain intensity recordings per day, compared across groups. The single-center trial is conducted at Zuckerberg San Francisco General Hospital and excludes patients who cannot use the assigned recording method or who lack pain sensation.
