Largest hospitalist physician group practices

Many physicians join together to form physician groups, creating a medical alliance that allows them to offer their patients comprehensive care, improved coordination, and convenient access. With the breadth and diversity of the U.S. physician group market, those interested in selling their healthcare product, software, or service to a physician group should first segment the market by specialty type and size.

Below, we’ve compiled a list of the largest hospitalist physician group practices using PhysicianGroupView and the Atlas Dataset.

How many hospitalist physician group practices are there in the U.S.?

The Definitive Healthcare database shows that there are 138 active hospitalist physician group practices in the U.S. However, since physician groups often have multiple locations to accommodate all the physicians in their network, the number of hospitals at which these physicians work can be expected to be higher.

Why target hospitalist physician groups?

Physicians in hospitalist practices specialize in caring for inpatients in a hospital setting. Some hospitalists have additional training in specialties such as pediatric medicine, family medicine, or internal medicine.

Hospitalists and their teams need the right technology, equipment, and training to ensure smooth hospital operations. Providing solutions that benefit this specialty can make them an ideal target for your offerings. Furthermore, by centralizing their purchasing decisions, large hospitalist physician groups can lead to even larger contracts.
