HMO. 1995 Mar-Apr;36(2):73-4.
Last fall, Group Health Association of America (GHAA) surveyed plans that are participating in the Childhood Immunization Program (see p. 29). The 121 HMOs that responded reported on a variety of immunization interventions. The survey is not representative of all HMOs because of the size of the response rate. Nevertheless, the survey provides an interesting snapshot of the immunization tactics that these HMOs are employing.
去年秋天，美国团体健康协会（GHAA）对参与儿童免疫计划的机构进行了调查（见第29页）。做出回应的121家健康维护组织（HMO）报告了各种免疫干预措施。由于回应率的规模，该调查并不代表所有的健康维护组织。尽管如此，该调查提供了这些健康维护组织正在采用的免疫策略的有趣概况。
