15 largest Mammography Quality Standards Act hospitals

Breast cancer is one of the most prevalent cancers in the world. It’s one of the deadliest cancers among American women in particular, second only to lung cancer in mortality rate.

Mammograms—x-ray images of the breast—are one of the most widely used and effective methods for early detection of breast cancer in people who show no signs of disease. Studies suggest that routine screening mammography can reduce breast cancer deaths in women after the age of 40.

Under the Mammography Quality Standards Act (MQSA), the Food and Drug Administration (FDA) regulates equipment, personnel and practices at mammography facilities through accreditation, certification and inspection.

The following table lists 15 MQSA-accredited hospitals with the highest number of staffed beds, a key indicator of a facility’s care capacity.

Which MQSA hospital has the most staffed beds?

Jackson Memorial Hospital in Miami, Florida, tops our list with 1,486 beds. That’s just under 2% more than Baptist Medical Center in San Antonio, TX, the MQSA facility with the second-highest bed count at 1,463.

Interestingly, the hospital with the highest patient revenue is the fourth-largest in terms of bed count: the Cleveland Clinic Main Campus in Cleveland, OH, out-earns the rest of the list with $5,241,664,591 in net patient revenue. This facility also leads in per-discharge revenue at $107,890.

When organized by per-discharge revenue, the top three MQSA hospitals by number of staffed beds actually fall into the bottom third of the list, suggesting that facilities capable of processing a larger volume of patients are more likely to see patients with less severe conditions and who require fewer expensive procedures before discharge.

Why is the MQSA important?

In 1985, the FDA conducted the annual Nationwide Evaluation of X-ray Trends and found that 36% of mammography facilities were producing x-ray images of unacceptable quality. Furthermore, they found that 15% of facilities were using x-ray equipment not designated for mammography.

In response, the American College of Radiology (ACR) began to offer a voluntary accreditation program in hopes of bringing these facilities to a higher standard. Nearly a third of all participating facilities failed to meet accreditation standards on their first application.

The ACR and U.S. Congress worked together to develop legislation that would make these standards mandatory and regulated at a federal level. On October 27, 1992, the MQSA was written into law.

The MQSA is important because it ensures that people undergoing mammograms can expect high-quality imagery and safety-focused practices, supporting early breast cancer detection and maximizing their chance of survival.

Under the MQSA, mammography facilities must provide patients with a “lay report” of their results in plain language, as well as their original mammogram images upon request. The Act also provides patients with a consumer complaint system and notifies patients who have visited a facility later deemed to be substandard.
