Infection

Acute severe pelvic inflammatory disease (PID).

  • All patients should be discussed with Gynaecology and referred to GUM.
  • Pregnancy test
  • Vaginal/cervical examination and documentation
  • Sexual health screen including microscopy and Chlamydia/gonococcal NAAT and culture and venous blood for HIV/Syphilis. Testing for Mycoplasma genitalium is recommended for women presenting with possible PID and the male partners of confirmed Mycoplasma genitalium infection. Abnormal cervical discharge is associated with PID; however, absence of cervical white cells on microscopy makes PID extremely unlikely (negative predictive value 95%, compared to positive predictive value just 17%).
