Frequency of Unscheduled Visits to the Obstetrical Triage Assessment Unit by Pregnant Adolescents in an Urban Canadian Centre Compared with a Matched Cohort of Pregnant Women

Abstract

Objectives: People from marginalized and vulnerable populations present more frequently for unscheduled, emergency obstetrical services at labour and delivery triage units. Based on our clinical experience, pregnant adolescents visit the obstetrical triage assessment units (OTAU) more often than adults do. This study was designed to assess this phenomenon by quantifying and describing the frequency of unscheduled visits to the OTAU by pregnant adolescents (age <20 y) compared with a matched cohort of adult pregnant patients (age ≥20 y).

Methods: A retrospective database review was performed for data on all adolescent patients that delivered at our institution at ≥20 weeks gestation between January 1, 2013, and December 31, 2017. Adolescent pregnant patients were matched in a 1:1 ratio with adult pregnant patients. Demographic and clinical characteristics as well as the number of visits to the OTAU were recorded.

Results: A total of 162 adolescent pregnant patients visited the OTAU during the study period. The mean number of visits to the OTAU by adolescents was 2.77 ± 2.40 compared with 1.96 ± 1.80 visits in the adult cohort (P = 0.0001). Adolescents were 63% more likely than adults to access triage services (incidence rate ratio [IRR] 1.63; 95% CI 1.09-2.44, P = 0.017). Diagnosis of a mental health condition was the only identified risk factor for accessing OTAU, irrespective of age (IRR 1.64; 95% CI 1.05, 2.55, P = 0.029).

Conclusions: Adolescent pregnant patients tend to visit the OTAU on an unscheduled basis more often than do adult patients. The presence of a mental health condition was identified as an important predictor of unscheduled visits to OTAUs for adolescent patients.
