Should a patient in Australia who tested positive for Chlamydia trachomatis and Neisseria gonorrhoeae be managed with telehealth treatment (ceftriaxone intramuscular injection plus doxycycline, or azithromycin if doxycycline contraindicated) or referred to a sexual‑health clinic, given a poor history of attending appointments?

Start Treatment Immediately via Telehealth

Given this patient's poor history of attending appointments, you should initiate treatment immediately via telehealth rather than referring to a sexual health clinic—the risk of loss to follow-up and continued transmission far outweighs any theoretical benefit of specialist evaluation for uncomplicated co-infection.

Treatment Regimen

For dual gonorrhea and chlamydia infection, prescribe:

• Ceftriaxone 500 mg IM single dose (arrange for patient to receive injection at nearest pharmacy, urgent care, or GP clinic that day) 1, 2
• PLUS Doxycycline 100 mg PO twice daily for 7 days (preferred over azithromycin) 3

Why Doxycycline Over Azithromycin for Chlamydia?

Doxycycline is superior to azithromycin for chlamydia treatment, particularly in rectal infections and non-gonococcal urethritis. Recent meta-analysis shows doxycycline achieves 93% cure rates versus 81% for azithromycin (OR 2.525, p=0.005) 4. The 2025 European guideline explicitly recommends doxycycline as first-line over single-dose azithromycin 5.

However, adherence is your critical concern here. Studies show 18% of patients don't pick up doxycycline prescriptions, and non-adherent patients have 3.6-fold higher ED return rates 6.

Addressing the Adherence Problem

Given poor appointment attendance history:

1. Directly observe the first doxycycline dose during your telehealth visit (have patient take it on camera)
2. Arrange same-day ceftriaxone injection before ending the consultation—call ahead to confirm appointment
3. Provide explicit written instructions about completing the full 7-day doxycycline course
4. Schedule a brief telehealth check-in at day 3-4 to verify medication adherence
5. Consider azithromycin 1g single dose as alternative ONLY if you genuinely believe doxycycline compliance is impossible 3, 7

Critical Management Points

Partner Notification

All sexual partners within the past 60 days require evaluation and treatment for both infections 3. Instruct patient to:

• Abstain from sex for 7 days after completing treatment AND until partners are treated
• Provide partners with information to seek immediate treatment

No Test of Cure Needed

Patients treated with recommended regimens don't require test of cure unless symptoms persist 3. However, retest in 3 months is recommended due to high reinfection rates 8.

When to Refer to Sexual Health Clinic

Refer if:

• Pharyngeal gonorrhea (requires specific consideration as harder to eradicate) 9
• Symptoms persist after treatment (culture with susceptibility testing needed)
• Pregnancy (doxycycline contraindicated; requires erythromycin or amoxicillin for chlamydia) 3
• Allergy to cephalosporins (requires alternative regimens)
• Suspected treatment failure (requires culture, susceptibility testing, and public health notification) 9

Why Telehealth Works Here

The evidence shows that same-day presumptive treatment is standard practice in STD clinics, with ~86% of treatments prescribed on the day of testing 10. Delaying treatment by referring to a specialist clinic in a patient with poor follow-up creates substantial risk of:

• Continued transmission to partners
• Loss to follow-up (your patient's established pattern)
• Development of complications (PID in women, epididymitis in men)

The key is ensuring the ceftriaxone injection happens immediately—this is non-negotiable and requires active coordination during your telehealth visit to arrange same-day IM administration.
