Schnucks supermarkets already have pharmacies, floral shops and cooking classes. The suburban St. Louis chain is now branching into health care, opening its first Schnucks Infusion Solutions facility to treat acute and chronic conditions. Infusion therapy involves injecting medicine through a needle or catheter. It treats conditions ranging from infectious diseases to immune deficiencies to cancer. The St. Louis Post-Dispatch reports that nurses, pharmacists and technicians at the center prepare infusions and administer them there or at the patients' homes. St. Louis-based health care consultant Michael Abrams says infusion centers are profitable because they administer expensive treatments.
