A study conducted by researchers from Harvard University Medical School and published in The American Journal of Medicine concluded that continuous contact-free monitoring on a medical-surgical unit is associated with a significant decrease in patients’ total length of stay in the hospital, code blue events, and intensive care unit (ICU) stay time for patients who had an intra-hospital transfer from the medical-surgical unit.

 In the controlled 7,643-patient study, researchers compared a 33-bed medical-surgical unit (intervention unit) to a sister control unit for a nine-month pre-implementation and a nine-month post implementation period. Outcome results showed a decrease in the overall length of stay by 0.37 days, a reduction of 9 percent. The average stay in the ICU for patient transferred from the medical-surgical unit was significantly lower in the intervention unit post-implementation by about two days, a 45 percent reduction. Furthermore, the rate of code blue events decreased by 86 percent.
