To determine the magnitude of and the reasons for missed opportunities to immunise with tetanus toxoid at a tertiary health institution in Nigeria. The information obtained would be used in developing an intervention strategy for eliminating missed opportunities in the future.
Missed opportunity was assessed by using the Revised WHO/EPI protocol (WHO/EPI/MLM/91.7). Exit interviews were carried out on pregnant women visiting the antenatal (prenatal) clinic to register the present pregnancy.
A tertiary health institution in Nigeria.
Pregnant women who attended the antenatal clinic for the purpose of registering the present pregnancy during the last two booking days in February, 1997 and the first booking day in March, 1997.
Missed opportunities and contributory factors.
The prevalence of missed opportunity was 66%. The factors responsible for missed opportunity were poor history taking, lack of knowledge of the current schedule of immunisation, dependence on physician referral for immunisation and inefficient immunisation record keeping system.
The findings establish the need for providing physicians in antenatal settings with an update on current immunisation policy and practice and for improved documentation of immunisation histories.
确定尼日利亚一家三级医疗机构中破伤风类毒素免疫接种错失机会的程度及原因。所获信息将用于制定未来消除错失机会的干预策略。
采用修订后的世界卫生组织/扩大免疫规划方案（WHO/EPI/MLM/91.7）评估错失机会情况。对前来产前（孕期）诊所登记本次妊娠的孕妇进行出院访谈。
尼日利亚一家三级医疗机构。
1997年2月最后两个预约日及1997年3月第一个预约日期间，前往产前诊所登记本次妊娠的孕妇。
错失机会及促成因素。
错失机会的发生率为66%。导致错失机会的因素包括病史采集不佳、对当前免疫接种计划缺乏了解、依赖医生转诊进行免疫接种以及免疫接种记录保存系统效率低下。
研究结果表明，有必要向产前机构的医生提供当前免疫接种政策和实践的最新信息，并改善免疫接种史的记录。
