Effectiveness of blood pressure educational and evaluation program for the improvement of measurement accuracy among nurses

摘要

Aim: To assess the procedure for measuring blood pressure (BP) among hospital nurses and to assess if a training program would improve technique and accuracy. Methods: 160 nurses from Molinette Hospital were included in the study. The program was based upon theoretical and practical lessons. It was one day long and it was held by trained nurses and physicians who have practice in the Hypertension Unit. An evaluation of nurses' measuring technique and accuracy was performed before and after the program, by using a 9-item checklist. Moreover we calculated the differences between measured and effective BP values before and after the training program. Results: At baseline evaluation, we observed inadequate performance on some points of clinical BP measurement technique, specifically: only 10 % of nurses inspected the arm diameter before placing the cuff, 4 % measured BP in both arms, 80 % placed the head of the stethoscope under the cuff, 43 % did not remove all clothing that covered the location of cuff placement, did not have the patient seat comfortably with his legs uncrossed and with his back and arms supported. After the training we found a significant improvement in the technique for all items. We didn't observe any significant difference of measurement knowledge between nurses working in different settings such as medical or surgical departments. Conclusions: Periodical education in BP measurement may be required, and this may significantly improve the technique and consequently the accuracy.
