The objectives of this study were to assess the case ascertainment and completeness of neonatal tetanus (NT) reporting and to estimate the incidence of NT in Dadu District, Pakistan.
We conducted active surveillance and hospital record reviews for suspected NT cases. We compared the cases of NT reported to the routine surveillance system with the cases identified through the hospital record reviews for 1993 through 2003. The two-source capture-recapture method was used to evaluate case ascertainment in the routine surveillance system and to estimate the incidence of cases of NT.
Active surveillance and hospital record reviews identified 134 cases in addition to 274 cases in the routine surveillance system. The two-source capture-recapture method indicated that there would have been 463 cases during this period (95% confidence interval (CI)=418-508), representing an average annual incidence of 0.62 per 1000 live-births. The overall completeness of routine reporting was 59.2%. The proportions of cases reported were 68.1% for government hospitals and 53.8% for private reporting sites.
Reporting of NT cases is incomplete. Active promotion of private sector participation, community involvement, and strengthening of the government sector as a way of improving NT reporting and surveillance is strongly suggested.
本研究旨在评估新生儿破伤风（NT）报告的病例检出率和完整性，并估计巴基斯坦达都地区 NT 的发病率。
我们对疑似 NT 病例进行了主动监测和医院病历回顾。我们将 1993 年至 2003 年期间通过常规监测系统报告的病例与通过医院病历回顾发现的病例进行了比较。采用双源捕获-再捕获方法评估常规监测系统中的病例检出率，并估计 NT 病例的发病率。
除常规监测系统中的 274 例病例外，主动监测和医院病历回顾还发现了 134 例病例。双源捕获-再捕获法表明，在此期间将有 463 例病例（95%置信区间（CI）=418-508），平均年发病率为 0.62/1000 活产儿。常规报告的整体完整性为 59.2%。政府医院报告的病例比例为 68.1%，私人报告点为 53.8%。
NT 病例报告不完整。强烈建议积极促进私营部门参与、社区参与以及加强政府部门，以提高 NT 报告和监测工作。
