Pain on a surgical ward: a survey of the duration and intensity of pain and the effectiveness of medication.

The effectiveness of analgesic medication for post-surgical pain was surveyed in a surgical ward of a large general hospital. Since earlier studies have shown that pain generally decreases rapidly and is negligible by the fourth day after surgery, the patients in the survey were assigned to 2 groups: those given analgesics during the first 4 days after surgery, and those given analgesics for pain after the fourth day. The results show that the patients with pain that persists beyond day 4 comprise a substantial proportion of the patients in a surgery ward (31%), are older, tend to use more words to describe their pain, and are helped less by their prescribed analgesic medications. This group is prescribed lower doses of analgesics and receives them more frequently; however, this prescription strategy appears to be ineffective since 26% of these patients report increased pain after medication compared to only 2% in the group that received analgesics during the first 4 days.
