Assessment

Signs and Symptoms

Discharge may be accompanied by itch, odour, or bleeding

History and Examination

If empirical treatment fails then examination, endo-cervical and high vaginal swabs are indicated

Differential Diagnosis

  • Physiological discharge is common and seen particularly after a change in contraception. If there is no itch, odour, or blood then reassure, but examine if persists
  • Itch predominant - candida most likely
  • Odour prominent - bacterial vaginosis most likely
  • Post-menopausal atrophic vaginitis and bacterial overgrowth can co-exist
  • Group A, C, and G streptococci less common but important cause postmenopausally
  • Other STIs - if high risk then GUM referral most appropriate
  • Malignancy
  • Fistula
  • Foreign body

Red Flags

Bleeding or blood stained discharge- follow appropriate post coital, inter-menstrual, post-menopausal bleeding Clinical Referral Guidelines.

Suspicion of malignancy on examination – 2ww gynaecology

Investigations

In the absence of red flag symptoms empirical treatment and a self-taken Lower Vaginal Swab for chlamydia in sexually active women are appropriate first line investigations.

Failure of empirical treatment should prompt examination, Endo-cervical Swab and High Vaginal Swab - ensure that adequate clinical details are available to microbiology on the request form e.g. 'post-menopausal vaginal discharge, no response to clotrimazole'

If symptoms persist and there is a strong clinical suspicion of infection, based on examination, and microbiology results have not identified a cause, then consider discussing with the local laboratory about the need to do more extended testing on a repeat swab

Formulary chapter 7.2.2 - vaginal and vulval infections

Management

If empirical treatment is successful, but recurrent symptoms, retreat.

See formulary treatment of vulvovaginal candida, treatment of bacterial vaginosis, and Recurrent Vulvo-Vaginal Candidiasis

Formulary chapter 5 - Genital tract infections

Post-menopausal discharge - both bacterial overgrowth and atrophy are likely to be reduced with use of topical oestrogens.

Treat as guided by microbiology, if this fails discuss with microbiology and consider referral to GUM.
