Centerpoint Medical Center is undergoing a major expansion, adding 36 hospital beds and other facilities in a $59 million project announced Wednesday.

“It’s a very exciting day for us,” said Phil Buttell, the hospital’s chief operating officer.

The hospital has had a faster-than-expected growth in demand since it opened in 2007, and that’s caused HCA Health Midwest to look at expanding, something the company had in mind in the hospital’s original design, he said.

Work on the expansion will likely begin in early 2017. It will include:

An added floor on the south tower of the hospital and two on the north tower. One of those two on the north tower will be shelled in but left unused until needed in the future.

Thirty-six added hospital beds in the north tower.

Twelve beds for the intensive-care unit, in addition to the 28 the ICU currently has.

A new 16-bed unit for physical medicine and rehabilitation.

Other work had been going on at Centerpoint as well. An expansion of the emergency room is to be completed next month. Buttell said the hospital had 57,000 ER visits in 2009 and 72,000 last year.

“People have grown to trust us as a health care provider for the community,” Buttell said.

Work also is continuing on the Sarah Cannon Cancer Center at 39th and Jackson Drive, on the southeast corner of the Centerpoint campus. It opens late this summer.

“That project has gone along very well,” Buttell said.

Overall, demand at the hospital has been rising and is expected to continue doing so.

“I think we’ve been successful in making this a health care destination in Eastern Jackson County,” Buttell said, adding that it consistently draws patients from much of western Missouri.

HCA Health Midwest on Wednesday announced a total of $93 million in projects. In addition to the $59 million at Centerpoint, Research Medical Center in Kansas City will get $23 million to add 42 beds and other facilities, and Lee’s Summit Medical Center will get $11 million for a third floor for added medical and surgical care.
