title: A New Strategy for Trichomonas Testing Female Adolescents in the Emergency Department.
abstract: OBJECTIVE
  Sensitive trichomonas diagnostic testing has become available, including nucleic acid amplification tests (NAATs) and a rapid antigen test. The study purpose was to determine if adding sensitive trichomonas testing to routine female sexually transmitted infection (STI) evaluations would increase trichomonas identification and treatment.
  
  
  METHODS
  Two study time periods. Study time 1 (T1) was used for a retrospective review. Study time 2 (T2) was used for a prospective study.
  
  
  METHODS
  Emergency Department.
  
  
  METHODS
  Symptomatic female patients aged 13-20 years (N = 447).
  
  
  METHODS
  Implementation of routing trichomonas testing in the Emergency Department during T2.
  
  
  METHODS
  Trichomonas diagnosis and treatment rates were compared during T1 and T2.
  
  
  RESULTS
  During T1 31 of 234 of eligible patients (13%) were trichomonas-tested. Laboratory-confirmed trichomonas was identified in 3 of 234 (1.3%). During T2, 212 of 213 of eligible patients (99.5%) were trichomonas-tested; 39 of 212 tested trichomonas-positive (18.4%); 29 of 212 tested rapid trichomonas antigen test-positive (13.6%; P < .001), and 33 of 188 tested trichomonas NAAT-positive (15.5%; P < .001). Trichomonas treatment was given to 3 of 3 laboratory-confirmed trichomonas cases during T1 (100%) compared with 37 of 39 during T2 (95%; P = .688). During T1, 14 of 17 women who received trichomonas treatment (82.4%) did not have a laboratory-confirmed trichomonas diagnosis and during T2 13 of 52 women without a laboratory-confirmed trichomonas diagnosis (25%) were treated for trichomonas (P < .001). Rapid trichomonas antigen tests and trichomonas NAATs were concordant in 178 of 188 patients (94.6%).
  
  
  CONCLUSIONS
  Incorporating trichomonas rapid antigen tests and NAATs into routine female adolescent STI testing significantly increased the number of laboratory-confirmed adolescent trichomonas diagnosis and treatment and are useful Emergency Department STI screening tools.
