Medication titration to pain relief.

Most visits (84%) resulted in relief of pain (score of 2 or greater on a scale of 0-4) over the 5-year period, as previously described (A). Of patients attaining relief, 60% experienced relief within 2 hours, and 90% experienced relief within 4 hours (B). Patients who had 1 to 5 visits per year experienced a greater magnitude of relief in half the time compared with patients who had more than 5 visits per year (C).
