Immediate Needs (within 7 days)
• Immediate safety
• Treatment of injuries
Should take precedence over clinical
management
Vaginal tears
Palatal Petechaie
Clinical Management
• Emergency Contraception
• STI screening follow up
• BBV testing/Serum save
• STI Prophylaxis
• Hep B prophylaxis
• HIV PEPSE
The need for any/all of these should start with a
detailed sensitively taken sexual history
EMERGENCY CONTRACEPTION
Offered to all women and adolescents
who have had
• Unprotected vaginal sexual intercourse
• Potential failure of contraceptive method
e.g. recent missed pills
EMERGENCY CONTRACEPTION
• Levonelle 2
• ellaOne
• Copper IUCD
Fast track client
Infections
STI identification is unlikely to assume
evidential importance except in certain
circumstances
• Young people – children and adolescents not
previously sexually active
• Elderly – if no recent consensual sexual activity
• Sexually inexperienced orifice
Chain of evidence
Finding an STI may influence the level of criminal injuries
compensation
Screening for STIS
• What, if any examination required?
• What tests to take and from what sites?
Infections
Most commonly identified STIs after
sexual assault
• Chlamydia- Dual NAAT
• Gonorrhoea – Dual NAAT+/- culture
• Trichomoniasis - direct microscopy
Offer all clients an examination
• if declines then self swab is sufficient to
test for chlamydia and gonorrhoea where
dual NAAT testing is available – should be
done at time of presentation and repeated
if necessary after 2 weeks
• Remember to sample all sites affected
In a Primary Care setting where dual NAAT
testing available
• If examined –Dual NAAT from all sites
affected and in female complaining of
vaginal discharge do HVS.
• if declines examination then can self swab
from all sites affected
Consider referral to specialist services if
symptomatic
STI ANTIBIOTIC PROPHYLAXIS
Consider
• In situations where patient may default
• Unable to tolerate the distress of repeat
examination
• Requires IUCD for EC
STI ANTIBIOTIC PROPHYLAXIS
Advantages
• Reduce the need for tests
• Lesson chance of missed infection
• Decrease the chances of detecting a
bacterial STI
STI ANTIBIOTIC PROPHYLAXIS
Disadvantages
• Unnecessary treatment
• Reinforcing belief that high risk of infection
• Missing out on partner notification
STI ANTIBIOTIC PROPHYLAXIS
First line antibiotics
• Cefixime 400mgs
• Azithromycin 1g
• Metronidazole 2g
BBV Screen/Serum save
• Offered to all at presentation
HEP B VACCINATION
Should be offered to victims of sexual
assault – risk assessment- if risk unknown then should be given
May be of value up to 6 weeks after event
Super-accelerated course recommended as more rapid protection and
adherence better
Vaccination interval 0, 1, 3 weeks and 1 year
High risk of hep B- Immunoglobulin ASAP and no later than 7 days
PEPSE
POST EXPOSURE PROPHYLAXIS
FOR HIV FOLLOWING
UNPROTECTED SEXUAL EXPOSURE
PEPSE
RISK OF HIV TRANSMISSION =
RISK THAT THE SOURCE IS HIV
POSITIVE x RISK OF EXPOSURE*
(*including cofactors such as co-existing
sexually transmitted infections, high viral
load and bleeding/trauma)
PEPSE

BASHH RECOMMENDATION FOR
PRESCRIBING PEP
BASHH RECOMMENDATION FOR
PRESCRIBING PEP
Factors influencing the effectiveness of PEP as identified in
the BASHH guidelines are:
• Delay in starting treatment, with PEP seen as possibly
less effective or ineffective after 72 hours but possibly
still considered if exposure is ‘high risk’
• Drug-resistant strains of HIV may reduce PEP’s
effectiveness with resistance testing of the ‘source’ of
infection considered and/or factoring in resistance when
prescribing PEP drug combinations
• HIV remaining in parts of the body where antiretroviral
drugs’ ability to penetrate is variable
• Poor adherence to the PEP drug regime
PEPSE
SIDE EFFECTS
Mild
• Nausea and diarrhoea- supportive treatment
with Domperidone and Loperamide
Serious
• Lipid abnormalities
• Liver problems
• Diabetes and insulin resistance
PEPSE
PRESCRIBING RECOMMENDATIONS
• Nucleoside reverse transcriptase inhibitors
(NRTIs)
• Non-nucleoside reverse transcriptase
inhibitors (NNRTIs)
• Protease inhibitors (PIs)
PEPSE
Current pack consists of the following drugs:
TRUVADA
• Tenofovir 245 mg once daily
• Emtricitabine 200mg once daily
KALETRA
• Ritonavir boosted Lopinavir 2 tablets twice daily
Initial pack contains 5 days supply
Treatment given for 4 weeks
28 day course cost around £650
Follow up
• Repeat STI screen 2 weeks after sexual
assault
• Pregnancy testing
• HIV testing- can be done at 1 and 3
months (4 months if taken PEPSE)
• Syphilis testing- 3 months
• Hep B and C testing - at 3 and 6 months
• Review psychosocial needs and coping
