目的了解海口市常规免疫接种率监测情况,评价报告接种率的可信性。方法对2011-2014年常规免疫报告接种率监测结果,使用D值法、R值法、脱漏率以及与调查接种率比较法对报告接种率的可靠性进行评价。结果 2011-2014年报告接种率和调查接种率较高,均达到95%以上,但与估算接种率有差距,估算接种率在84.4%~123.8%之间;D值和R值对报告接种率进行综合评价为2011年不可信,2012、2013年均可信,2014年可疑;2013年的OPV和2014年的Hep B脱漏率均超过10%;报告接种率与调查接种率的比较,62.50%的差异无统计学意义。结论海口市常规免疫接种率监测质量有待进一步提高,流动儿童接种管理是稳定和提高该市常规免疫接种率监测质量的关键。
Objective To understand the routine immunization rate monitoring in Haikou City and evaluate the credibility of the reported vaccination rate. Methods The monitoring results of routine immunization coverage in 2011-2014 were used to evaluate the reliability of reported vaccination rates using D value method, R value method, leakage rate and comparison with survey vaccination rate. Results The inoculation rates and survey inoculation rates in 2011-2014 were all higher than 95%, but there was a gap between the inoculation rates and estimated inoculation rates between 84.4% and 123.8% The overall evaluation was untrustworthy in 2011, credible in 2012 and 2013 and suspicious in 2014. The OPV and 2014 Hep B leakage rate exceeded 10% in 2013; the reported vaccination rate compared with the investigation vaccination rate, 62.50% The difference was not statistically significant. Conclusion The routine immunization monitoring rate needs to be further improved in Haikou. The vaccination management of floating children is the key to stabilize and improve the routine immunization coverage monitoring in the city.
