Patient anxiety, pain, and satisfaction with image-guided needle biopsy

Image-guided percutaneous needle biopsy has become the preferred diagnostic modality for bone and soft tissue tumors. However, to the authors' knowledge, the levels of patient anxiety, pain, and satisfaction before and after the procedure have not been studied. Sixty-five patients undergoing image-guided needle biopsy of a possible bone or soft tissue tumor were prospectively surveyed to quantify preprocedure and postprocedure levels of anxiety and pain and to determine demographic and clinical correlates of anxiety, pain, and satisfaction. Anxiety was measured with the Spielberger State-Trait Anxiety Inventory, pain was measured with a visual analog scale, and satisfaction was measured by patient willingness to repeat the procedure if necessary. Statistical analysis was performed with Student's t test, Fisher's exact test, and linear regression analysis. Compared with preprocedure values, trait anxiety (defined as the underlying level of anxiety, P<.0011), state anxiety (defined as the current level of situational anxiety, P<.001), and pain (P<.05) decreased significantly postprocedure. The relationship between changes in pain and state anxiety was significant (r=0.31, P=.014), whereas no relationship was seen between changes in pain and trait anxiety (r=0.13, P=.28). Patients who were somewhat satisfied with the procedure reported higher levels of postprocedure pain than those who were completely satisfied (5.24±2.19 cm vs 1.70±2.08 cm, respectively; P<.001). In other words, lower levels of experienced pain correlated with patient satisfaction. Older age was inversely correlated with postprocedure pain (r=0.41, P=.001), and there was a trend toward increasing dissatisfaction among younger patients.
