Emergency physicians' patterns of treatment for presumed gonorrhea and chlamydia in women: one center's practice.

No indicator reliably predicts if a woman has gonorrhea or chlamydia (sexually transmitted diseases [STDs]) during an Emergency Department (ED) visit. Before culture results return, emergency physicians (EPs) must choose whom to treat. We evaluated EP treatment of STDs within our institution. EPs voluntarily completed anonymous surveys while evaluating women requiring both a pelvic examination and STD cultures, except for sexual assault victims. The questionnaires asked for patients' demographics, history, physical examination, and in-ED laboratory tests, and whether any particular section of the encounter caused treatment. The treated and untreated groups' characteristics, as reported by the examining physicians, were compared. There were 145 questionnaires returned over a 6-month period; 41/145 patients (28%) were treated for presumed STD-28 (68%) based on physical examination, 8 (19.5%) on history, and 5 (12.5%) on in-ED laboratory tests. Comparison of treated vs. untreated groups revealed no difference in patient demographics. The treated group had more historical positives (3.92 vs. 2.84, respectively; p < 0.001) and physical examination findings (3.39 vs. 1.24, respectively; p < 0.001) compared to the untreated group. Eleven patients (7.58%) had positive STD cultures, 4 (9.75%) in the treated group and 7 (6.73%) in the untreated group (p > 0.05). In our institution, EPs chose to treat patients with more historical and physical examination findings, not based on demographics. Our EPs' presumptive STD treatment paradigms do not accurately distinguish patients with positive pelvic culture results from those with negative results, supporting the available literature that describes the difficulty of this diagnosis. Individual EDs must recognize this infection identification problem and, after assessment of their treatment population, institute either a liberal presumptive STD treatment regimen for all comers, or establish reliable and timely follow-up for women left untreated.
