St. Lawrence et al. demonstrate dramatically that physicians in practice do a less than stellar job of screening for sexually transmitted diseases (STDs).1 The need to screen for STDs has been well demonstrated in recent studies from Baltimore, Md, where 7.9% of the population aged 18 through 35 years tested positive for gonorrhea or chlamydia by nucleic acid amplification tests on urine samples.2 Physicians can increase their screening. This has been demonstrated in Kaiser Permanente pediatric clinics in California. Physicians in the intervention clinics increased chlamydia screening of sexually active adolescent girls coming in for routine checkups and saw a concomitant decrease in average chlamydia detection rates.3
In both studies, urine testing was well tolerated by the patients. Unfortunately, urine screening is not always well tolerated by insurance companies. The reference laboratory used by our institution charges $46.36 for a chlamydia DNA probe test that can be done on endocervical specimens but not urine. The cost of the urine nucleic acid amplification test is $111.00. Many insurance companies are reluctant to pay the additional costs. The American Academy of Pediatrics passed a resolution in 1999 calling for funding of noninvasive urine testing for sexually transmitted diseases. Other medical societies and advocates for public health should join together in calling for more screening using noninvasive testing. This should increase the volume of tests being done and allow the cost per test to decrease without putting any undue financial burden on insurance companies or laboratories.
On the other hand, insurance companies could lead the way and encourage noninvasive testing by negotiating with laboratories for lower costs. This could be a win-win situation. Patients would appreciate the noninvasive testing, physicians would do more screening, and the insurance companies wouldnt lose money on noninvasive testing. Therefore, STD rates would decline and the public health would be better served.
