Educating interventional radiology personnel in nonpharmacologic analgesia: effect on patients' pain perception.

RATIONALE AND
OBJECTIVES: The purpose was to evaluate the effects on patients' pain perception of educating interventional radiology personnel in nonpharmacologic analgesia.
MATERIALS AND METHODS: Ninety-six patients undergoing lower-extremity arteriography or percutaneous nephrostomy were asked to rate the pain they experienced during the procedure on a scale of 0 to 5 (0 = no pain, 1 = mild pain, 2 = moderate pain, 3 = severe pain, 4 = very severe pain, 5 = worst pain possible). Patients were studied at two baseline sessions (baseline 1, December 1993 to August 1994, n = 15; and baseline 2, September 1995 to January 1996, n = 11) and after the staff underwent one of two training sessions (posttraining 1, January 1995 to July 1995, n = 34; posttraining 2, January 1996 to April 1996, n = 36). Training targeted nurses and technologists and included rapport skills, correct use of language and suggestions, distraction, relaxation training, and self-hypnosis. Data were evaluated with analysis of variance for repeated measures.
RESULTS: The mean pain scores reported after training were lower (1.48) and matched an "acceptable" pain score of 1.52 more closely than those reported under baseline conditions (2.54, P = .001). There was a tendency toward reduced use of intravenously administered agents for conscious sedation after training. There were no statistically significant differences in the pain scores between patients who underwent arteriography and patients who underwent nephrostomy overall (1.76 and 1.78, respectively), at baseline (2.58 and 2.43, respectively), and after staff training (1.49 and 1.42, respectively).
CONCLUSION: Interventional radiology personnel trained in nonpharmacologic analgesia methods can help reduce patients' pain perception during interventional procedures.
