The null hypothesis of this study was that a prematurity prevention program that uses computerized prenatal risk assessment, educational interventions administered on a weekly basis by telephone, enhanced nutritional support, and referral to a perinatologist whenever necessary will result in no difference in the number of neonates admitted to the neonatal intensive care unit (NICU). A retrospective cohort study was designed to compare the number of admissions to the NICU for the 12 months before initiation of the prematurity prevention program with those during the first 12 months of the full working program. Compared with the year before program initiation, the prematurity prevention program resulted in a 56% reduction in the number of NICU admissions, a 49% reduction in preterm deliveries with subsequent admission of the infant to the NICU, and a 59% reduction in NICU hospital days. In addition, there was a 38% reduction in preterm deliveries caused solely by preterm labor. The null hypothesis is rejected because a comprehensive prematurity prevention program resulted in a significant reduction in NICU admissions, preterm deliveries with admission to the NICU, and NICU hospital days.
本研究的零假设是,一个采用计算机化产前风险评估、每周通过电话进行教育干预、加强营养支持并在必要时转诊至围产医学专家的早产预防项目,不会使入住新生儿重症监护病房(NICU)的新生儿数量产生差异。一项回顾性队列研究旨在比较早产预防项目启动前12个月与全面实施该项目的头12个月期间NICU的入院人数。与项目启动前的一年相比,早产预防项目使NICU入院人数减少了56%,早产分娩后婴儿入住NICU的情况减少了49%,NICU住院天数减少了59%。此外,仅由早产引起的早产分娩减少了38%。零假设被拒绝,因为一个全面的早产预防项目显著减少了NICU入院人数、早产分娩后入住NICU的情况以及NICU住院天数。
