Syndromic Management of STI John Q. Wong, MD, MSc 20 November 2010
STI Case Management • History-taking and examination • Diagnosis and treatment, using flowcharts • Counseling and education on safer sex, including condom promotion and provision • Partner management • Data gathering (recording)
Traditional approaches to STI diagnosis • Etiological diagnosis • Lab tests to identify the causative agent • Clinical diagnosis • Clinical experience to identify symptoms typical for a specific STI
Etiological approach • Treatment has to wait for lab results • Testing facilities not available • Lab tests not ideal for some STIs • H. ducreyi not easily cultured • C. trachomatis tests are expensive and invasive • Syphilis requires a special microscope and training
Clinical diagnosis • Some STIs cause similar symptoms • Mixed infections are common
The third way: syndromic case management • Problem-oriented (patient’s symptoms) • Highly sensitive and does not miss mixed infections • Treats the patient at the first visit • Makes STI care more accessible (primary care level) • Uses flowcharts • Provides opportunity and time for education and counseling
Criticisms of the syndromic approach • Not scientific • Studies have shown similar diagnostic accuracy as clinical diagnosis, except for syphilis • Tanzania used syndromic approach in 1995 trial • 50% reduction in urethritis in men • Reduction in syphilis • 38% reduction in HIV
Criticisms of the syndromic approach • Too simple for a physician - can even be used by nurses • Just like thermometers and stethoscopes • Use by other service providers also an advantage • More time for education for behavior change
Criticisms of the syndromic approach • Fails to make use of a service provider’s clinical skills and experience • Studies have shown that clinicians using their own clinical judgment misdiagnose 50% of the time • Treat patient for the most common cause, then treat for a second cause if symptoms do not improve • Most patients do not return to the health center • Patient will continue to transmit the STI
Criticisms of the syndromic approach • Results in waste of drugs because patients are being over-treated • Studies have shown that syndromic approach is less expensive • Gram stain should be included in STI diagnosis • Delay in treatment • Costly • Quality assurance required
