Immunization information systems (IISs) are confidential, computerized information systems that collect and consolidate vaccination data from multiple health-care providers, generate reminder and recall notifications, and assess vaccination coverage within a defined geographic area. A CDC program goal for 2010 is to achieve >or=95% participation in an IIS (defined as having two or more recorded vaccinations) among children aged <6 years. To monitor progress toward this goal, CDC annually surveys immunization grantees in 50 states, five cities, and the District of Columbia, using the Immunization Information Systems Annual Report (IISAR). All 56 grantees were asked to complete the IISAR; 52 did so for 2008. This report highlights results from the 2008 IISAR, which indicated that 75% of all U.S. children aged <6 years (approximately 18 million children) participated in an IIS in 2008, an increase from 65% in 2006. The majority of grantees (82%) reported that their IIS had the capacity to track vaccinations for persons of all ages, compared with 70% in 2006. Data-quality measures of timeliness and completeness indicated that in 2008, 67% of IIS data were received and processed within 30 days of vaccine administration, and data were reported for six of 17 core data elements in >or=90% of IIS records (both measures are similar to 2006 results). Increased provider use of electronic health record systems can benefit IISs and their users by producing immunization records that are more timely and complete.
免疫信息系统（IIS）是一种机密的、计算机化的信息系统，用于从多个医疗保健提供者收集和整合疫苗接种数据，生成提醒和召回通知，并评估特定地理区域内的疫苗接种覆盖率。美国疾病控制与预防中心（CDC）在 2010 年的一个项目目标是使 6 岁以下儿童的免疫信息系统参与率达到>或=95%（定义为有两次或以上记录的疫苗接种）。为了监测这一目标的进展，CDC 每年使用免疫信息系统年度报告（IISAR）对 50 个州、5 个城市和哥伦比亚特区的免疫接种拨款接受者进行调查。所有 56 个拨款接受者都被要求完成 IISAR；其中 52 个在 2008 年完成了这一报告。本报告重点介绍了 2008 年 IISAR 的结果，表明 2008 年，75%的所有 6 岁以下美国儿童（约 1800 万儿童）参加了免疫信息系统，比 2006 年的 65%有所增加。大多数拨款接受者（82%）报告说，他们的免疫信息系统有能力跟踪所有年龄段的人的疫苗接种情况，而 2006 年这一比例为 70%。及时性和完整性数据质量指标表明，2008 年，67%的免疫信息系统数据在疫苗接种后 30 天内收到并处理，在 17 个核心数据元素中有 6 个的报告率超过 90%（这两个指标与 2006 年的结果相似）。提供者越来越多地使用电子健康记录系统可以通过生成更及时和完整的免疫记录，使免疫信息系统及其用户受益。
