It is unknown how physician specialties other than gastroenterologists utilize endoscopic ultrasound in managing gastrointestinal malignancies.
Dr Nuzhat Ahmad and colleagues assessed the proportion of gastroenterologists, oncologists, and surgeons using endoscopic ultrasound.
The research team also assessed the general availability of endoscopic ultrasound.
In addition, the team determined which factors are associated with the use and availability of endoscopic ultrasound.
A self-administered questionnaire was mailed out to 1,200 randomly selected gastroenterologists, oncologists, and surgeons throughout the United States.
The data was analyzed from 521 responses.
There were 60% respondents who had endoscopic ultrasound available within their practices.
The researchers found a greater availability of endoscopic ultrasound within the practices of surgeons of 81%, and 87% within academic practices.
Endoscopic ultrasound was also more available in practices that serve a population of more than 500,000.

The team observed that 71% of respondents utilized endoscopic ultrasound in their practices.
There was a similar utilization of endoscopic ultrasound across specialties.
There was greater utilization of endoscopic ultrasound in academic centers, in practices that served a community of more than 500,000.
The researchers noted that endoscopic ultrasound use was also higher among respondents who had been in practice for less than 5 years.
Employing logistic regression models for utilization of endoscopic ultrasound, and lesser number of years in practice.
The team found that the availability of endoscopic ultrasound were found to be the only significant predictors of utilization.
Dr Ahmad's team concluded, “The majority of practitioners utilized endoscopic ultrasound in management of gastrointestinal malignancies.”
“There was similar utilization of endoscopic ultrasound across specialties.”
“Endoscopic ultrasound is available to the majority of practitioners who manage gastrointestinal malignancies.”
