Cervical Screening Test (OSCE)
Introduction
- Greet patient and introduce yourself
- Confirm patient details ✍
- Briefly explain the procedure in a patient friendly manner
- Tell the patient a chaperone will be present throughout and why
- Get patient consent ✅
- Check the patient is not in any pain or pregnant 🤰
- Ask the patient to use the toilet if necessary
- Ask patient to remove underwear whilst you leave the room
- Wash hands ✋
Equipment
Disposable gloves ✋
Paper towels
Speculum and light 🔦
Lubricant
Sample pot
Endocervical brush
Inspection
- Don gloves ✋
- Ask patient to lie in the supine position then move their heels to their bottom, relaxing their knees so that they fall outwards
- Assess the vulva to identify abnormalities
Scars: indicate prior surgery or lichen sclerosus
Masses: indicates Bartholin’s cyst or vulval malignancy
Ulcers: indicate genital herpes
Varicosities: varicose veins due to pelvic obstruction (e.g. malignancy) or chronic venous disease
White lesions: patchy, surrounding vulva or anus, indicates lichen sclerosus
Vaginal atrophy: typically present in post-menopausal women 👵
Abnormal vaginal discharge: indicates bacterial vaginosis, candidiasis, chlamydia or gonorrhoea
4. Assess for vaginal prolapse (lump protruding from vagina - ask patient to cough to make it more obvious)
What is Bartholin’s cyst ❓
Bartholin’s glands maintain the moisture of the vagina by producing secretions
Cysts form if the glands become blocked or infected
Cysts are usually unilateral, with fluctuating mass, can be tender or not
What is Lichen sclerosus ❓
Chronic inflammatory dermatological condition
Affects anogenital region
Symptoms: puritis, thickened white patches, scarring, adhesions, shrunken labia, narrow introitus, clitoris obscuration
What causes abnormal discharge ❓
Candidiasis: curd-like discharge, itchy and inflamed
Bacterial vaginosis: this, fishy-smelling, not itchy or inflamed 🔥
Trichmoniasis: frothy, yellow discharge, itchy and inflamed 🔥
Chlamydia/gonorrhoea: purulent discharge, may be inflamed or not
Insert speculum
- Get patient consent to insert speculum ✅
- Separate labia
- Gently insert speculum sideways
- Rotate speculum 90° and open blades to achieve optimal visualisation of the cervix 📐
- Tighten locking nut to fix the blades in this position
Cervix visualisation
Inspect cervix:
Masses: indicate cervical malignancy
Ulcers: indicate genital herpes
Open cervical os: indicates inevitable/incomplete miscarriage
Erosion surround os: indicates ectropion or early cervical cancer
Abnormal discharge: indicates trichomonas, bacterial vaginosis, candidiasis, chlamydia or gonorrhoea
What is cervical ectropion ❓
Columnar epithelial cells present outside vaginal cervix, often around external os
These cells are red in comparison to the pink cervix
They often present with post-coital bleeding due to fine blood vessels
What is cervical cancer ❓
Caused by persistent HPV (human papillomavirus) infection
Cervical intraepithelial neoplasia (dysplastic cells) may precede it
Symptoms: often asymptomatic in early stages, increased vaginal discharge, vaginal bleeding, vaginal discomfort, cervix may have white/red patches indicates early stages, ulcers/tumours indicate late stages
Cervical screening
- Insert endocervical brush into endocervical canal through speculum (do not touch the brush against the sides of the speculum)
- Rotate brush clockwise 5 times 🔄
- Remove endocervical brush (do not touch the brush against the sides of the speculum)
- Put the tip of the endocervical brush in a liquid based cytology container
Speculum removal
- Loosen locking nut
- Close blades slightly
- Rotate speculum 90° (inspect vaginal walls simultaneously) 📐
- Use sheet to cover patient
- Tell patient the examination is complete and you will leave the room to allow them to change ✅
- Appropriately dispose of waste
- Wash hands ✋
Completion
- Label samples appropriately ✍
- Thank patient
- Inform patient they will receive results via method requested
- Document procedure ✍
- Send swabs to the lab to process
Summary:
- Greet the patient and explain the procedure
- Inspect the vulva to identify abnormalities
- Insert speculum into vagina and fix into place by tightening locking nut
- Inspect the cervix to identify abnormalities
- Perform cervical screening by inserting endocervical brush into endocervical canal through speculum and rotating
- Remove speculum by loosening locking nut, closing blades and rotating
- Complete the procedure by thanking patient and sending swabs to lab
