Utility of pelvic examination in assessing women with bleeding in early pregnancy: a multicenter Canadian emergency department study.

backgroundBleeding in early pregnancy is a common emergency department (ED) presentation. Although variability in approaches has been demonstrated, research is relatively uncommon on practices and outcomes. This study investigated the influence of clinical pattern of care, utility, and contribution of pelvic examination aimed at diagnosing and managing bleeding in early pregnancy at three Canadian EDs.

methodsAfter obtaining informed consent, data were collected from adult women who were pregnant and from treating ED physicians using a structured questionnaire. We defined the change in management based on the initial clinical plan at the time of the initial physician assessment in the ED and any subsequent changes made after the pelvic examination was performed. Patient telephone follow-up was supplemented by linking with provincial administrative data for births. Univariable and multivariable binary logistic regression analyses were performed to identify factors associated with a change in patient management following pelvic examination in the ED.

resultsOverall, 200 women were enrolled. The mean age was 31 years, patients had been bleeding for a median of 1 day and stayed in the ED for a median of 5 h. Of these, 166 (83.0%) received a pelvic examination, including speculum examination and/or bimanual palpation. Pregnancy outcome data were available for 192 pregnancies; 107 (56%) experienced a miscarriage. Factors significantly associated with a change in management after pelvic examination in the univariate logistic regression analysis were brown/dark-red bleeding per vaginam (physician determined), tachycardia, right lower quadrant tenderness, and bimanual palpation. In the multivariate logistic regression analysis, brown/dark-red bleeding per vaginam was independently associated with a reduced likelihood of a change in management after pelvic examination (aOR = 0.37; 95% CI: 0.14-0.98).

conclusionAmong women presenting to the ED with bleeding in early pregnancy prior to 20 weeks gestation, only brown/dark-red vaginal bleeding, potentially indicative of bleeding resolution, significantly independently influenced the baseline odds of a change in management after pelvic examination. Until the debate on the utility of pelvic examination in the ED for this presentation is resolved, physician preferences and shared decision making with patients should guide practice regarding speculum examination/bimanual palpation for the management of bleeding in early pregnancy.
