Antibiotic Stewardship

Antibiotic stewardship is a coordinated program that promotes the appropriate use of antibiotics, improves patient outcomes, and decreases the spread of infections caused by multidrug-resistant organisms.

Misuse and overuse of antibiotics is one of the world’s most pressing public health problems. Infectious organisms adapt to the antimicrobials designed to kill them, making the drugs ineffective. People infected with antimicrobial-resistant organisms are more likely to have longer, more expensive hospital stays, and may be more likely to die as a result of an infection.

Pain Management Platform

Medication monitoring is an objective clinical tool for health care professionals who need clear, reliable information about their patients’ use or misuse of prescribed medications, non-prescribed medications, or illicit substances to make informed clinical decisions regarding treatment.
