A Case-Control Study of the Effects of Implementing the Registered Nurses' Association of Ontario Guidelines for the Assessment and Management of Postoperative Pain and the Use of Relaxation Therapy in 312 Patients with Bone and Soft-Tissue Malignancy.

BACKGROUND The present study aimed to investigate the effects of implementing the Registered Nurses' Association of Ontario (RNAO) guidelines for the management of postoperative pain and the use of Jacobson's relaxation technique (JRT) in patients with bone and soft-tissue malignancy at a single center in China. MATERIAL AND METHODS A total of 312 patients were recruited and randomly divided into 2 groups. In the intervention group, the RNAO pain-management technique of JRT was adopted, while the control group received the standard institutional nursing management. Pain scores after the operation, according to the Numerical Rating Scale (NRS) combined with the Wong-Baker Faces Pain Rating Scale and Short-Form McGill Pain Questionnaire, were compared between the 2 groups. Nursing satisfaction was compared as well. RESULTS At 6, 24, and 72 h after the operation, the NRS scores combined with the Wong-Baker Faces Pain Rating Scale in the intervention group were significantly lower than those in the control group (P<0.001); 72 h after the operation, the Pain Rating Index, Visual Analogue Scale, present pain intensity, and total scores for the intervention group were significantly lower than those for the control group (P<0.001 for all 4 scores). The scores reported from the patients for nursing response and consequent care (P<0.001), nursing competence (P=0.029), and surgical pain-control satisfaction (P<0.001) in the intervention group were also significantly higher than those in the control group. CONCLUSIONS JRT can improve postoperative pain-control and nursing satisfaction in patients with malignant bone and soft-tissue tumors. These data suggest a benefit for application of JRT in clinical care.
