Post-coital bleeding

Definition/Description

  • Non-menstrual bleeding that occurs after sexual intercourse.
  • Post-coital bleeding is predominantly cervical in origin.
  • Main causes are:
    • Cervical ectropion (34%).
    • Cervical polyp (5-13%).
    • Cervicitis (STIs - usually chlamydia) (2%).
    • CIN (7-17%).
    • Cervical cancer (0.65--4%).
  • Rare causes include syphilis, herpes simplex, vaginal atrophy, vaginal cancer, pelvic organ prolapse, endometrial cancer, endometriosis, trauma.
  • No specific cause is identified in 50% of cases.

Red Flag Symptoms

  • Postmenopausal Bleeding (PMB) i.e. bleeding >12 months after last period over age 55.
  • Consider a suspected cancer pathway referral (for an appointment within 2 weeks) for women if, on examination, the appearance of their cervix is consistent with cervical cancer (new NICE recommendation for 2015).

Guidelines on Management

  • History, including sexual health history. Think Chlamydia under age 25.
  • Routine examination and swabs (remember increased risk of chlamydia if aged < 25 or change of sexual partner).
  • Perform smear ONLY if due.
  • If an ectropion is found- consider change in contraception as ectropions are commonly hormone-induced.
    • Note ROUTINE CRYOTHERAPY for treatment of an ectropion is not routinely performed as high risk of recurrence and risk of scarring
  • If find cervical polyp, see guidance
  • Consider USS if normal appearance of cervix, to exclude endometrial pathology.

Referral Criteria/Information

Indications for referral

  • If PCB > 6 months or bleeding is particularly heavy.
  • Cervical pathology- 2ww for suspicious features, routine referral for large polyp, ectropion present or childbirth related superficial trauma/ scarring.
  • Consider early referral in women over age 40
     

Information to include in referral letter

  • Describe problem (cycle, quantify e.g. pad usage, duration) and effect on quality of life / activities of daily living
  • FBC and USS results 
  • Current contraception
  • Smear history (including last smear & result) the patient will still be seen without this but if you include it automatically, this will speed up the appointment.
  • Treatment options please include what has been tried and whether it has been effective
     

Investigations prior to referral

  • Chlamydia screening (better taken as ECS when presenting with PCB).
  • High Vaginal Swab
  • Pelvic USS
  • Smear test (only if due)
N.B. DO NOT perform a cervical smear if outside the screening programme
