Summary
Clinician technique significantly impacts pharyngeal gonorrhea detection rates. Inducing a gag reflex during throat swab collection was associated with higher detection rates in this study.
Area of Science:
- Microbiology
- Clinical Diagnostics
- Public Health
Background:
- Pharyngeal gonorrhea is a significant public health concern.
- Accurate diagnosis relies on effective sample collection techniques.
- Variability in diagnostic yield has been observed.
Purpose of the Study:
- To investigate the impact of individual clinician technique on pharyngeal gonorrhea detection rates.
- To identify factors associated with successful pharyngeal gonorrhea diagnosis.
Main Methods:
- Analysis of 6721 pharyngeal gonorrhea culture results.
- Data collected from 43 clinicians.
- Correlation of detection rates with clinician-reported gag reflex induction during swabbing.
Main Results:
- Significant variation in detection rates among clinicians (0%-10%, median 1.3%).
- Detection rates were positively associated with the frequency of gag reflex induction (P < 0.05).
Conclusions:
- Clinician technique, specifically gag reflex induction, is a critical factor in pharyngeal gonorrhea detection.
- Standardizing or optimizing swabbing techniques may improve diagnostic accuracy for pharyngeal gonorrhea.

Description
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...

A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...
