Factors Associated with Meeting Obstetric Care Consensus Guidelines for Nulliparous, Term, Singleton, Vertex Cesarean Births

Objective This study aimed to identify factors associated with meeting the Obstetric Care Consensus (OCC) guidelines for nulliparous, term, singleton, and vertex (NTSV) cesarean births. Materials and methods This was a retrospective case control study of women with NTSV cesarean births between January 2014 and December 2017 at single tertiary care center. Demographics and clinical characteristics were compared between women with NTSV cesarean births which did or did not meet OCC guidelines. A multivariable logistic regression model was used to evaluate the effect of each variable on the odds of meeting OCC guidelines. Results There were 1,834 women with NTSV cesarean births of which 744 (40.6%) met OCC guidelines for delivery and 1,090 (59.4%) did not. After controlling for confounding factors, the odds of meeting OCC guidelines were increased for in-house providers managing with residents (adjusted odds ratio [aOR] = 2.03, 95% confidence interval [CI]: 1.44–2.87) and without residents (aOR = 1.66, 95% CI: 1.30–2.12), compared with non-in-house providers managing without residents. There was no significant difference in the odds of meeting OCC guidelines for in-house providers managing with or without residents (aOR = 1.23, 95% CI: 0.84–1.79). Conclusion After adjusting for confounding factors, in-house provider coverage, regardless of resident involvement, is associated with increased odds of NTSV cesarean births meeting OCC guidelines. Key Points: Frequency of adherence to OCC guidelines for NTSV cesarean births was 40.6%. Neither patient demographics nor comorbidities was associated with the odds of meeting OCC guidelines. In-house providers are associated with increased odds of meeting OCC guidelines.
