To evaluate the application of a five-tiered Obstetrical Triage Acuity Scale (OTAS) in a tertiary care center by assessing the relationship between the triage score and admission rates.
A retrospective chart review over a 2 month period in 2014 was conducted. The previously validated OTAS score for obstetrics was assigned to each patient. Seven scoring parameters were used to assign a final score, stratified into 5 categories: 1) resuscitative, 2) emergent, 3) urgent, 4) less urgent, and 5) non-urgent. Characteristics of patients assigned to each scoring group were compared using the Chi-square test. Rates of admission amongst the groups were also compared.
Eight hundred and thirty five patients were included. The mean gestational age of patients was 35.9 weeks. The median number of triage visits was 2 (1–11) with 112 (13.4%) patients classified as triage super users (above 5 visits). The most frequently assigned scores were level 4 (34.7%) and level 2 (32.1%). Only 4 patients were assigned a level 1. Hospital admission rates were significantly associated with OTAS score. Seventy-five percent of level 1, 56.9% of level 4 and 53.8% of level 3 women were admitted. Most level 5 (87.1%) and level 2 (65.9%) visits were discharged to home.
The OTAS in our population did not predict hospital admission, because level 2 patients were most likely to be discharged home. Level 3 and level 4 encounters were also likely to be admitted and delivered during the same visit; most term labor admissions will occur in these two levels.
