Shortly thereafter, it was announced that Boone County Hospital would be one of the first facilities in the nation to acquire a whole body scanner, which represented the very latest in radiological diagnosis.

Boone's board of trustees voted in 1988 to approve a 10-year lease agreement with Christian Health Services, thereby relinquishing county government's central role in the hospital's operation yet maintaining ownership of the plant and property.

In 1993, Christian Health Services merged with Barnes and Jewish hospitals in St. Louis to form BJC HealthCare.

The first phase of the plan remodeled the front entrance and lobby, created a new out-patient surgery waiting area, cardiac catheterization facilities and a women's health center.

[9] Boone Hospital Center completed a 940-space parking garage on its west side in 2010 and broke ground on a new 7-story, 128-room patient tower.

They, along with the University of Missouri Hospital ambulance service, provide emergency care for the entire county.
