Background: Abnormal uterine bleeding (AUB) influences 20–30% of women sooner or later in their regenerative years and regularly cause women to look for urgent or emergent care. Purpose: To describe the population of women seeking urgent medical attention for abnormal uterine bleeding (AUB), in terms of symptoms, medical history, and clinical examination findings; and to determine characteristics associated with anaemia in this population. Materials and Methods: We implemented a retrospective cohort study of patients comprehended in King Abdulaziz Hospital Emergency Room for abnormal uterine bleeding from November 2016 to May 2017 (n=126). Data collected included demographic factors, laboratory and radiologic findings, clinical history, and physical examination findings. We calculated pervasiveness ratios for moderate to severe anaemia (defined as haemoglobin less than 10 g/dL) and sensitivity and specificity of clinical characteristics for recognizing women with anaemia. Results: The median age of patients was 33 years (range 14–68 years). Nearly half (47.6%) had a concurrent medical condition which could affect their treatment options and 15 had moderate to severe anaemia. The only factors related with moderate to severe anaemia were having both tachycardia and hypotension; duration of bleeding more than 7 days: and haemoglobin of less than 10 g/dL in the previous year. Conclusions: A substantial proportion of patients looking for urgent medical care for abnormal uterine bleeding had potential contraindications for the mainstays of treatment. Clinical symptoms and bleeding history were poorly predictive for moderate to severe anaemia in this population of women.
