About USAP

Innovators, collaborators and leaders

USAP is the highest quality, single-specialty, anesthesia practice in the country. We’re owned and clinically governed by practicing physicians, including some of the world’s foremost experts in anesthesia. Our anesthesiologists, CRNAs, CAAs, and all members of our care teams share operational and clinical best practices organization-wide, helping to facilitate the delivery of consistent, high-quality services for patients, surgeons, facilities, and payers.

At USAP, clinical excellence is supported by a world-class business leadership team. Our capital partners are Welsh, Carson, Anderson & Stowe; Berkshire Partners; and GIC. All three are investment firms with significant experience investing in and building leading healthcare companies.

Together, we’re changing the way perioperative services are delivered.

Excellence is in our DNA

USAP was founded in 2012 to provide leading, high-quality groups of anesthesiologists with a strategic partner that allows anesthesia providers to focus on what they do best—create positive patient outcomes.

Our visionary leaders created an exciting new approach to anesthesia care, building on our rich history, collective expertise, high-quality practices and innovative processes to meet the challenges of a changing healthcare industry, provide exceptional patient experiences and deliver excellent clinical outcomes.

Shaping the future of anesthesia

USAP’s unique, single-specialty partnership model creates an organization in which each and every partner is invested in our success. We’re blending our high-performing, forward-thinking cultures to build an entity that is better, stronger and more innovative than we could be alone.

We’re passionate about collaborating and discovering trends by applying the latest medical research to our practice through our  IT tools, quality measurement capabilities and utilization of patient data.

Through this we have been able to create:

  • Advanced analytics for efficient OR staffing
  • Quality and charge capture at the point of care for every case
  • Intelligent adoption of new medications, devices and techniques
  • A national system for collecting and analyzing adverse events
  • A best-in-class revenue cycle management system
  • An evidence-based, perioperative blood management process that promotes the optimal use of blood products
