BACKGROUND: We hypothesized that receiving cervical length screening (CLS) would be associated with a lower incidence of preterm birth (PTB) among patients with a history of PTB.
METHODS: Patients who delivered live and stillborn infants at Baylor Scott & White Medical Center - Temple from January 1, 2023, to December 31, 2023 and had a medical history of PTB were included in the analysis. We performed a bivariate analysis between patients who did and did not have PTB. We then performed a multivariate logistic regression to determine which variables were independently associated with PTB.
RESULTS: There were 2756 births during the study period, and 185 patients met inclusion criteria. Tricare versus commercial insurance (adjusted odds ratio [aOR] 3.39; 95% confidence interval [CI] 1.17-9.80; P = 0.02) and receiving CLS (aOR 2.82; 95% CI 1.37-5.81; P = 0.005) were independently associated with PTB. The c-statistic of this multivariate model was 0.68.
DISCUSSION: Tricare versus commercial insurance and receiving CLS were associated with a 239% and 182% increase, respectively, in the chance of PTB. It is possible that unmeasured variables among patients who had CLS were associated with PTB.
