The cost-effectiveness of counseling by telephone and by clinic visit contacts were compared in 40 hypertensive patients each of whom received counseling and reinforcement every three weeks for six months regarding diet, exercise, smoking, and coping with stress. Blood pressure declined significantly in both counseling groups (N: 10 each) but not in a control group (N: 20). The cost per patient under control was $82 for the clinic counseling and $39 for the telephone counseling strategy, suggesting that telephone counseling was a cost-effective technique.
对通过电话咨询和门诊咨询的成本效益进行了比较，研究对象为40名高血压患者，他们每三周接受一次关于饮食、运动、吸烟和应对压力的咨询及强化指导，为期六个月。两个咨询组（每组10人）的血压均显著下降，而对照组（20人）血压未下降。门诊咨询每位患者的成本为82美元，电话咨询策略每位患者的成本为39美元，这表明电话咨询是一种具有成本效益的技术。
