Abstract
Background: Preterm birth is one of the main causes of neonatal morbidity and mortality. Cervicometry measured by ultrasonography is a tool that could predict preterm birth. Objective: to establish the validity of cervicometry determined by ultrasonography and preterm delivery. Methodology: this is an observational, retrospective, diagnostic test validation study. We reviewed 400 medical records of pregnant women whose delivery was attended at the José Carrasco Arteaga Hospital, from January 2018 to December 2019 and who had an ultrasound with a cervicometry report between 22 and 36 weeks of gestation. The information was collected using a data collection form. The analysis was performed in the SPSS 15.0 program. Sensitivity, specificity, positive predictive value, negative predictive value and ROC curve were determined. Results: the prevalence of preterm birth was 31%; 23.3% were classified as late preterm. According to the measurement of the cervical canal, 88.3% were categorized as low risk of preterm birth. The sensitivity of the cervicometry was 32.61%, the specificity 47.58%, the positive and negative predictive value 58.06% and 24.08%; the area under the curve was 0.63. Conclusions: cervicometry did not demonstrate in this study predictive capacity of preterm birth.
