Differential diagnosis of acute abdominal pain of the childbearing age woman is a difficult challenge to the emergency physician. Clinical scoring systems for pelvic inflammatory disease (PID) and acute appendicitis have already been introduced. We want to validate these scoring systems externally.
This study was conducted at a single urban teaching hospital emergency department from May 2011 to September 2013. Retrospective analysis of a prospectively collected registry for reproductive-aged women was performed.
A total of 1432 patients were registered. Among them, 322 patients diagnosed as PID (177 patients) or acute appendicitis (145 patients) were finally analyzed in this study. Among the PID and acute appendicitis scored, lower and higher cut-off points were 3 and 8 for PID risk score, and 6 and 10 for appendicitis risk score. PID risk score of PID patients was 7.0 (+/-1.9), acute appendicitis patients was 4.3 (+/-2.1), and other patients was 4.0 (+/-2.2) (p<0.001). Appendicitis risk score of PID patients was 5.7 (+/-1.9), acute appendicitis patients was 9.0 (+/-2.1), and other patients was 5 (+/-1.6) (p<0.001). The areas under the receiver operating characteristic curves were 0,832 and 0,950 for diagnosis of PID with PID risk score and acute appendicitis with appendicitis risk score, respectively.
These scoring systems have appropriate diagnostic power for diagnosis of PID and acute appendicitis.
