About Mosaic Infusion Solutions

The healthcare services market is expanding rapidly and is driven by increasing healthcare costs that are moving patients into the most cost-effective delivery settings. Other contributing factors are: 

  • a growing bio-pharmaceutical pipeline of infusible and injectable medications
  • an aging population
  • the recent addition of a Medicare benefit for these products and services.

What are Specialty Infusion Centers?

Specialty infusion therapy services primarily involve the intravenous administration of medications in a controlled environment by a staff of highly trained Board-Certified Nurse Practitioners and Infusion Registered Nurses. Patients can receive treatment for a wide range of acute and chronic health conditions such as infections, auto-immune illnesses, pain, multiple sclerosis, hemophilia, asthma, osteoporosis and nutritional deficiencies.

These drugs do not fit into the retail drug distribution model as they are high cost, may need special handling and require extensive patient training and/or administration by a licensed clinician. Patients are generally referred to specialty infusion centers by physicians, hospital discharge planners, home-health agencies and managed care organizations.
