Purpose:
Ultrasound of the right lower quadrant for appendicitis requires specific training and practice. Improved visualization of the appendix can result in decreased utilization of computed tomography. Increasing the sensitivity of ultrasound for appendicitis thus decreases radiation exposure, reduces cost, and improves the patient healthcare experience in accordance with the three principles of the triple aim designated by the Institute for Healthcare Improvement. The purpose of this study was to examine the effect of a structured training program supplemented by technologist feedback on sonographic visualization of the appendix in a large pediatric health system.
Methods:
The baseline ultrasound visualization frequency was computed for 20 ultrasound technologists in a large pediatric health system. Following this, technologists were informed of their individual and relative performance. Those with visualization frequencies less than 75% were provided structured training by a designated sonographer with an appendix visualization frequency above 75% while those with greater than 75% visualization continued to be monitored and informed of their monthly frequency. Following this structured training, appendix visualization frequencies were monitored over the next 5 months.
Results:
There was no significant effect of sonographer career experience on the baseline appendix visualization frequency. Fourteen of 20 technologists demonstrated improved visualization frequencies post-intervention. The composite visualization frequency among these 20 technologists improved from 66.55 to 69.14%. This resulted in a potential savings of 38 CT scans during the post-intervention period.
Conclusion:
An appendix visualization rate monitoring program coupled with structured training was successful in improving the appendix visualization rate throughout a large pediatric health system. This program demonstrates the positive effect that monitoring and targeted intervention can have on a quality improvement program. The program continues to be carried out as part of a plan-study-do-act cycle.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
