Data are reported as number of patients (percentage)
Post-partum is defined as delivery in the prior 6 months. Abnormal vital signs (tachypnea and tachycardia) are reported for adults only. Tachypnea is defined as respiratory rate >20 breaths per minute. Tachycardia is defined as heart rate >100 beats per minute. Abnormal lung exam was defined as decreased breath sounds, wheezes, crackles, and/or rhonchi, though was left to the interpretation of the treating clinician at the time of the exam. Pediatric heart rate and respiratory rate were recorded however given variability of vital signs with change in age, we did not define tachycardia/tachypnea for children
