AB  - BACKGROUND: Obstetric and gynecological (OBGY) diseases are among the most 
      important differential diagnoses for young women with acute abdominal pain. 
      However, there are few established clinical prediction rules for screening OBGY 
      diseases in emergency departments (EDs). This study aimed to develop a prediction 
      model for diagnosing OBGY diseases in the ED. METHODS: This single-center 
      retrospective cohort study included female patients with acute abdominal pain who 
      presented to our ED. We developed a logistic regression model for predicting OBGY 
      diseases and assessed its diagnostic ability. This study included young female 
      patients aged between 16 and 49 years who had abdominal pain and were examined at 
      the ED between April 2017 and March 2018. Trauma patients and patients who were 
      referred from other hospitals or from the OBGY department of our hospital were 
      excluded. RESULTS: Out of 27,991 patients, 740 were included. Sixty-five patients 
      were diagnosed with OBGY diseases (8.8%). The "POP" scoring system (past history 
      of OBGY diseases + 1, no other symptoms + 1, and peritoneal irritation signs + 1) 
      was developed. Cut-off values set between 0 and 1 points, sensitivity at 0.97, 
      specificity at 0.39, and negative likelihood ratio (LR-) of 0.1 (95% CI: 
      0.02-0.31) were considered to rule-out, while cut-off values set between 2 and 3 
      points, sensitivity at 0.23 (95% CI 0.13-0.33), specificity at 0.99 (95% CI 
      0.98-1.00), and positive likelihood ratio (LR+) of 17.30 (95% CI: 7.88-37.99) 
      were considered to rule-in. CONCLUSIONS: Our "POP" scoring system may be useful 
      for screening OBGY diseases in the ED. Further research is necessary to assess 
      the predictive performance and external validity of different data sets.
