Are Emergency Physicians Too Aggressive With Empirically Treating Gonorrhea and Chlamydia In The Face of Rising Resistance? • FOEM Oral Abstract Competition • ACOEP 2014 Fall Conference • Xandus Chen, DO
Co-Authors XandusChen, DOChristopher Komurek, DO Michael Samodio, DO Kelly King, DOScott Plasner, DO Aria Health, Philadelphia
Background • Neisseria Gonorrhea (NG) and Chlamydia Trachomatis (CT) are the highest reported sexually transmitted diseases (STD) in this country and across the globe • Philadelphia is ranked #4 as of 2011 • CDC recommends a low threshold to treat higher risk patients
Background • Significant part of the patient population seen at ARIA-Frankford ED are higher risk patients • EM physicians commonly empirically treat patients with STD complaints for NG/CT before the PCR result are available • Results take 2-3 days • Concern that NG/CT will develop resistance
Background • NG resistant to prior 1st line agents • PCN and fluoroquinolones • Increased antibiotic dosing • Dual therapy recommended • Evidence that CT has capability to express resistant phenotypes
Objective/Hypothesis Objective: Establish the percentage of patients with actual infection from those who were empirically treated for NG/CT Hypothesis: Despite working with a higher risk population in our ED, overtreatment of patients without NG/CT infections occur at a higher rate than expected
Methods • Design: Retrospective study • Setting: ARIA –Frankford ED is an urban community ED in Philadelphia • Patient Selection: 100 patients randomly selected • Medically evaluated at ARIA-Frankford ED • Received empiric treatment for NG/CT • Had endocervical or urethral sample collected for NG/CT PCR testing
Main Outcome Measures • Percentage of infected patients among those who received empiric treatment • Frequency of STD-concerning symptoms and history • Dysuria • Discharge • Partner concerns • Prior STD testing • Prior STD history
Results • 21/100 patients had positive NG/CT cultures • 11 patients had NG, 6 patients had CT, 4 had both • When comparing patients infected with NG/CT to all patients, higher percentage complained of STD-concerning symptoms and history • Dysuria (52% vs 28%) • Genital discharge (81% vs 60%) • Partner concerns (24% vs 16%) • Prior testing (52% vs 33%) • Prior STD history (43% vs 16%)
Results • 17/44 male (39%) were infected • When comparing male patients infected with NG/CT to all male patients, higher percentage complained of: • Dysuria (53% vs 39%), • Penile discharge (82% vs 61%) • Partner concerns (29% vs 25%) • Prior STD testing (59% vs 32%) • Prior STD history (53% vs 23%)
Results • 4/56 females (7%) were infected • When comparinginfected females to all females, higher percentage complained of: • Dysuria (50% vs 11%) • Discharge (75% vs 33%) • Prior STD testing (25% vs 19%) • Lower percentage of infected females complained of: • Partner concerns (0% vs 5%) • Prior STD history (0% vs 6%)
Discussion 79% of patients did not have NG/CT NG was 50% more prevalent than CT infections Males had higher incidence of infection (39%) Females had lower incidence of infection (7%)
Discussion • Patients who were positive for NG/CT more commonly complained of STD-concerning symptoms and history • Complaints were nonspecific • Discharge was the most common complaint of infected patients (82%) • 48% of males WITHOUT infection also complained of discharge • 5 patients were positive for CT/NG several times within 3-5 month span
Discussion • Disadvantage of overtreatment • Increasing resistance • Higher cost of medical care • Longer time spent in ED • Risk of allergic reaction • Increased risk of C. Difficile infection • Anxiety and social stigma of STD infection
Discussion • Disadvantage of postponing treatment until positive PCR results • Patients lost to follow up • Continued transmission disease • Consequences of no treatment: • PID • Epididymitis • Infertility (men and women) • Vertical transmission • Disseminated gonorrhea
Limitations • Sample size • Physician variable collection techniques • Numbers of patients with specific complaints were dependant on • Patients providing information • Medical documentation • Prior ARIA hospital visits
Conclusion Significant overtreatment in ED for NG/CT (79%) Low threshold to treat males Collect cultures for repeat infections STD-concerning symptoms and history are nonspecific Still recommend judicious empiric treatment for NG/CT
