Summary
Obstetric ultrasound use and spending increased between 2016 and 2022, with follow-up ultrasounds showing the fastest growth. Utilization dipped in 2020 due to the pandemic.
Area of Science:
- Medical Economics
- Health Services Research
- Obstetrics and Gynecology
Background:
- Obstetric ultrasound is a key diagnostic tool in prenatal care.
- Understanding utilization and expenditure trends is crucial for healthcare resource management.
- Previous analyses may not reflect recent changes in obstetric ultrasound practices.
Purpose of the Study:
- To analyze trends in obstetric ultrasound utilization and expenditures per live birth.
- To examine variations in use by ultrasound type and patient subgroups.
- To provide updated data for policymakers on resource allocation and reimbursement.
Main Methods:
- Retrospective cohort study using the Health Care Cost Institute commercial claims database (2017-2022).
- Analysis of obstetric ultrasound claims for live birth deliveries (≥28-week gestation).
- Descriptive statistics and negative binomial regression to identify utilization trends and correlates.
Main Results:
- An average of 5.3 obstetric ultrasound claims per live birth were recorded.
- Ultrasound utilization per live birth increased by 8.3% and spending by 5.6% (inflation-adjusted) over the study period.
- Follow-up ultrasound (CPT 76816) demonstrated the most significant growth; utilization decreased in 2020 during the COVID-19 pandemic.
Conclusions:
- Obstetric ultrasound utilization and expenditures have risen from 2016 to 2022.
- Identifying variations in ultrasound use patterns can inform policy decisions regarding resource management.
- Findings may guide reimbursement strategies, including bundled payment models for obstetric care.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

1.1K
Introduction:
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 issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
