'Sufficient Pain relief ' as a Practical Benchmark in Cancer Pain Management: A Prospective Study of Serial Pain Scores, Patient-rated Pain Relief and Perceived Sufficiency of Analgesics.

Objectives: Serial pain scores are used to guide pain management but there can be variability in what constitutes 'adequate' pain relief for an individual patient. We aimed to evaluate how patient-rated sufficiency of pain relief corresponded to pain scores, pain relief scores, and the felt need for increasing analgesics.

Material And Methods: Baseline and follow-up scores on the 11-point numerical rating scale (11-NRS) and verbal rating scale were obtained for116 patients with cancer pain.
