In one year, 3.85 percent of the 12,228 patient visits to a family practice clinic resulted in referral. The members of the health maintenance organization (HMO) had a referral rate of 4.46 percent, while fee-for-service patients had a referral rate of 3.19 percent. The fee-for-service patient population was similar to the HMO group, except for the significantly different rate of referral. Comparison of the referral patterns suggests that this difference is influenced by economic factors.
在一年时间里，一家家庭诊所的12228次患者就诊中有3.85%的就诊导致了转诊。健康维护组织（HMO）的成员转诊率为4.46%，而按服务收费的患者转诊率为3.19%。除了转诊率有显著差异外，按服务收费的患者群体与HMO组相似。对转诊模式的比较表明，这种差异受到经济因素的影响。
