Current state of pain care for hospitalized patients at end of life.

We report findings on the current state of pain care in hospitals for end-of-life (EOL) patients using longitudinal data from 8 diverse medical-surgical units located in 4 different Midwestern hospitals over 24 months. We identified 1425 EOL care episodes, 596 (41.3%) of which had a pain diagnosis. The percentage of EOL patients with pain varied significantly across units (P < .001) and was even lower (27.7%) for those with "acute confusion." Additionally, 30% of EOL patients had severe or significant pain at death or discharge to hospice and only 42.7% actually met the expected pain-related outcome ratings. Pain often improved within 48 hours of admission (P < .005), the improvement, however, stagnated following this initial time period (P = .92). A sizable gap between pain science and clinical practice continues.
