Sputum Studies II: Culture and Sensitivity01:20

Sputum Studies II: Culture and Sensitivity

1.9K
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,...

Summary
This summary is machine-generated.

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) techniques vary significantly among US endosonographers. Practice environment and procedure volume influence needle choice and repeat biopsy decisions.

Area of Science:

  • Gastroenterology
  • Endoscopic Ultrasound
  • Interventional Endoscopy

Background:

  • Fine needle aspiration (FNA) is a key diagnostic tool in endoscopic ultrasound (EUS).
  • Practices for EUS-FNA may differ based on endosonographer experience and setting.
  • Standardization of EUS-FNA techniques is an area of ongoing interest.

Purpose of the Study:

  • To investigate variations in fine needle aspiration (FNA) techniques used by endosonographers.
  • To correlate EUS-FNA practices with endosonographer experience, procedure volume, and practice environment.

Main Methods:

  • A cross-sectional survey study was conducted among United States-based endosonographers.
  • An anonymous online electronic survey assessed needle choice, FNA technique, and clinical decision-making.
  • Data were analyzed in relation to years in practice, procedure volume, and practice setting.

Main Results:

  • 210 endosonographers completed the survey; 51.4% were academic practitioners.
  • High-volume EUS (>150/year) and FNA (>75/year) performers were common (77.1% and 73.3%, respectively).
  • Academic physicians and high-volume EUS physicians were more likely to repeat non-diagnostic FNA with a core needle. Low-volume physicians were more likely to refer for alternative biopsies.

Conclusions:

  • Significant variability exists in EUS-FNA practices among US endosonographers.
  • Endoscopic ultrasound (EUS) volume and practice environment are associated with differences in EUS-FNA techniques.
  • Further research may be needed to optimize EUS-FNA protocols.
