The Shift Of Infusion Therapy Administration To Alternative Care Settings

The major trend that is driving growth in the U.S. infusion therapy market is the shift of procedures to alternative care settings such as specialty clinics, ambulatory surgery centers (ASCs), and home care settings. In the past, infusion therapy was primarily administered in hospitals or physicians’ offices. However, in recent years, there has been a shift toward alternative care settings, which offer a number of benefits to both patients and providers.

Specialty clinics offer an attractive option for infusion therapy patients because they often provide specialized care and expertise in the specific condition being treated. These clinics may offer a more comfortable and personalized setting, as well as shorter wait times and the ability to schedule appointments outside of traditional office hours. This can lead to improved patient satisfaction and better health outcomes.

Ambulatory surgery centers (ASCs) are another alternative care setting that has seen an increase in infusion therapy procedures. ASCs are equipped to handle more complex procedures than traditional outpatient clinics and offer patients the convenience of receiving infusion therapy without having to go to a hospital. Many ASCs are also able to offer lower costs for the same procedures performed in a hospital, making it an attractive option for both patients and providers.

Home care settings are also becoming a popular option for infusion therapy patients. Home infusion therapy allows patients to receive treatment in the comfort of their own homes, which can lead to increased patient satisfaction and a better adherence to treatment plans. Home infusion therapy also allows for more frequent monitoring of the patient's condition, which can lead to earlier detection of complications and improved patient outcomes.

Overall, the shift toward alternative care settings for infusion therapy procedures is a positive trend for the industry and for patients:

  1. Cost savings: Hospitals are typically the most expensive setting for infusion therapy, due to the high overhead costs associated with running a hospital. By contrast, specialty clinics and ASCs have lower overhead costs, which can translate into lower costs for patients. Home care settings can be even more cost-effective, as they eliminate the need for patients to travel to a medical facility for treatment.
  2. Convenience for patients: Specialty clinics and ASCs are often located in convenient locations, with ample parking and easy access for patients. Home care settings, of course, offer the ultimate in convenience, allowing patients to receive treatment in the comfort of their own homes.
  3. A higher level of personalized care: Hospitals are often crowded and busy, with little time for personalized attention from healthcare providers. By contrast, specialty clinics and ASCs are often smaller and more focused on individual patient needs. In the home, care providers can offer one-on-one attention to patients, ensuring that their needs are met and their treatment is administered safely and effectively.

The shift of infusion therapy procedures to alternative care settings has been driven in part by changes in reimbursement policies. In recent years, Medicare and private insurers have begun to reimburse providers for infusion therapy administered in non-hospital settings. This has made it more financially feasible for providers to offer infusion therapy in these settings, which has in turn led to an increase in demand for these services.

As the trend continues, we may see further innovations in delivery systems and technology to better facilitate the transition to these alternative care settings.
