MANAGEMENT
START antibiotic treatment immediately after a provisional diagnosis of PID is made and without waiting for STI test results . Australian guidelines for STI management in primary care recommend an antibiotic regimen to cover chlamydia infection , gonorrhoeal infection and anaerobic bacteria ( for example , with bacterial vaginosis [ see table 2 ]). 23

improving within 2-3 days of starting treatment . Remove the IUD if the woman is not improving or if the patient requests it . A discussion about alternative contraception should accompany any discussion about IUD removal . Once treatment is completed and the woman is completely asymptomatic with no residual tenderness , insertion of another IUD can occur if desired .
PROGNOSIS
THE long-term sequelae of PID include chronic pelvic pain , infertility and ectopic pregnancy . These complications can have severe impacts .

PID can result in tubal factor infertil-
for gonorrhoea . Metronidazole is recommended for anaerobic cover but may be poorly tolerated . 23
For pregnant or breastfeeding women with mild to moderate infection , use azithromycin in place of doxycycline ( see table 2 ). Use of azithromycin as a single dose immediately and one week later in lieu of doxycycline is also recommended for women who may not adhere to a daily medication regimen .
High levels of azithromycin resistance have led to Australian guidelines recommending a 14-day course of moxifloxacin for cases of PID with a confirmed M . genitalium infection ( note that moxifloxacin is not on the PBS ). 23 GPs are advised to consult with their laboratory or local sexual health clinic regarding management of PID from M . genitalium .

* If M . genitalium is confirmed , consult with laboratory or local sexual health clinic for advice regarding antibiotic treatment . Moxifloxacin 400mg daily for 14 days is recommended for M . genitalium associated PID cases . As M . genitalium results are often received about a week after PID treatment has begun , it may be reasonable to shorten the course of moxifloxacin to 10 days , because of the cost and potential toxicity of this drug .

after treatment completion or until symptoms have resolved . Provide advice and education ( including written information ) that includes how PID was acquired , the potential long-term consequences , how to take the antibiotics and how repeated infections can be prevented . The Australian STI Management Guidelines links to several PID factsheets for patients online .
Whether or not an STI is diagnosed , most PID is sexually transmitted . Therefore , notifying and treating sexual contacts is necessary . Australian contact tracing guidelines recommend treatment of current sexual partners to cover chlamydia and gonorrhoea irrespective of test results . 26 For women with chlamydia , gonorrhoea or M . genitalium associated PID , sexual partners from the past six months ( chlamydia ) or two months ( gonorrhoea ) should be contacted and offered testing and treatment .
ity and increases the risk of ectopic pregnancy . While the relationship between PID , tubal infertility and ectopic pregnancy is well known , quantifying the relationship between PID and these outcomes is difficult because of inconsistencies around the diagnosis of PID and the long follow-up needed to measure these outcomes . Cohort studies have reported higher infertility and ectopic pregnancy rates for women with PID compared with those without . 29 Among women treated for mild to moderate PID , 19 % were infertile , and less than 1 % experienced an ectopic pregnancy over the next three years . Women experiencing repeated episodes of
