Impact of point-of-care gonorrhea and chlamydia testing in the emergency department on reducing overtreatment rates.

BACKGROUND: Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections continue to increase in the United States. Advancement in technology with point-of-care (POC) testing can improve the overall treatment of sexually transmitted infections (STI) in the emergency department (ED) by shortening the time to test result and administration of accurate treatment. The purpose of this study was to assess if the POC test reduced the rate of overtreatment for CT and/or NG compared to the standard-of-care (SOC) test. METHODS: This retrospective cohort study included adult patients tested for CT and NG at two urban EDs between August 2020 and October 2022. This cohort excluded hospital admissions, elopement, pregnancy, rectal and oral samples, victims of sexual assault, and diagnoses for which antimicrobial treatment overlapped that of CT/NG. The primary outcome assessed overtreatment, defined as receiving treatment in the ED or a prescription prior to discharge for patients who tested negative for CT and/or NG. Secondary outcomes included undertreatment rates, overtreatment rates in select populations, test turnaround time, and ED length of stay (LOS). RESULTS: Of 327 patients screened, 97 patients were included in the SOC group and 100 in POC. Overtreatment for CT was provided in zero POC patients and 29 (29.9%) SOC patients (p < 0.001). NG was overtreated in 1 (1%) POC and 23 (23.7%) SOC (p < 0.001). POC was associated with undertreatment of CT and/or NG in two patients, compared to four patients tested with SOC. Overall, treatment was deemed inappropriate for 5 (5%) of those tested with POC, compared to 35 (36%) tested with SOC (p < 0.001). There was no difference in ED LOS (2.7 vs 3.01 h, p = 0.41). CONCLUSIONS: POC testing facilitated the return of results prior to patients being discharged from the ED. Compared to standard testing, POC improved appropriateness of CT and NG treatment by reducing the rates of overtreatment.

A Collaborative Intervention Between Emergency Medicine and Infectious Diseases to Increase Syphilis and HIV Screening in the Emergency Department.

BACKGROUND: Sexually transmitted infections (STIs) are a common reason for evaluation in the emergency department (ED). Given the overlapping risk factors for STIs, patients screened for gonorrhea and chlamydia should be tested for syphilis and HIV. Syphilis and HIV testing rates in the ED have been reported to be low. The study objective was to examine whether collaboration between emergency medicine (EM) and infectious disease (ID) providers improved syphilis and HIV testing in the ED. METHODS: A multidisciplinary team of EM and ID providers was formed to identify and address barriers to syphilis and HIV testing in the ED. Syphilis, HIV, chlamydia, and gonorrhea testing and infection rates were calculated and compared during 2 time periods: preintervention (January 1, 2012-December 30, 2017) and postintervention (November 1, 2018-November 30, 2019). We also extracted clinical and laboratory data from patients with positive syphilis and HIV results during the study period. RESULTS: The most commonly cited barrier to syphilis and HIV testing was concern about follow-up of positive results. Compared with the preintervention period, syphilis and HIV testing rates increased significantly in the postintervention period (incidence rate ratios, 30.70 [P < 0.0001] and 28.99 [P < 0.0001] for syphilis and HIV, respectively). The postintervention period was also associated with a significant increase in the identification of patients with positive syphilis and HIV results (incidence rate ratios, 7.02 [P < 0.0001] and 2.34 [P = 0.03], respectively). CONCLUSIONS: Collaboration between EM and ID providers resulted in a significant increase in syphilis and HIV testing and diagnosis in the ED.

Administration of progesterone produces mild sedative-like effects in men and women.

The goal of this study was to investigate the behavioral and subjective effects of a single dose of progesterone in men and women. Certain metabolites of progesterone (e.g., allopregnanolone) are potent positive allosteric modulators of GABA(A) receptors, and produce sedative-like effects in laboratory animals. This study was designed to examine the acute effects of these neurosteroids in humans. Women (n=7) in their early follicular phase and men (n=10) received intramuscular injections of progesterone (200 mg) or placebo. Dependent measures included plasma levels of progesterone and allopregnanolone, self-report measures of mood and subjective effects and behavioral measures of psychomotor performance. Plasma concentrations of progesterone and allopregnanolone increased reliably and with little intersubject variability after drug administration, and levels were similar in men and women. Administration of progesterone produced small, delayed increases in heart rate and feelings of fatigue, and it impaired smooth eye pursuit. These results suggest that, although the effects are modest and not simply related to plasma concentrations, progesterone and its metabolites can produce sedative-like effects in both men and women.
