Pinnacle Regional Hospital in Boonville on Wednesday announced that it would close its doors. The closure was effective 7 p.m. that day.

The "economic hardship of bringing the facility into compliance is too great to make the appropriate repairs necessary," a news release stated.

Calls to the hospital seeking more information were not immediately returned. The Missouri Department of Health and Senior Services provided a letter from hospital CEO Joe Conigliaro requesting a 90-day suspension of the hospital’s license. The 90-day suspension opens the door for other entities to possibly purchase the hospital despite its closure.

Patients seeking medical records can do so at the hospital’s emergency department through Jan. 29. All rural health and outpatient therapy clinic and hospital operations will cease, however. The hospital stopped admitting new patients Friday. The hospital listed job fair and career opportunities at other medical centers on its Facebook page for displaced staff at about 4 p.m. Wednesday.

The hospital announced the end of laboratory operations Friday due to regulatory issues. That meant it could no longer accept patients at the emergency room, according to a news release.

The decision to close the hospital was made after discussions between its leaders and the department. The hospital stopped performing surgeries after a December inspection found that issues with the building’s HVAC system caused the hospital's sterilization room to not have the right pressure, temperature and humidity.

The HVAC issue did not cause patient infections, Pinnacle CEO Joe Conigliaro said last week.

The hospital would have to rent a mobile sterilization unit for surgeries to continue, which would cost $300,000 for a two-month rental. The hospital had submitted a plan to the state to fix its HVAC issues and was working with Kansas City-based Design Mechanical even before the December inspection.

“It had nothing to do with the [operating rooms], it had nothing to do with unsafe practices or anything like that,” Conigliaro said. “It was just, your central sterile processing has to be up to standards where temperature, humidity and pressure is concerned.”

A hospital staff member commenting on the closure via Facebook asked the community to understand that the closure decision was beyond staff control.

"We did not ask for this to happen. At the end of the day this not only effects [sic] our lives personally, but we all have families and loved ones who depend on us," wrote Sara Wyatt Head, who noted she has worked at the hospital since 2006.

Boonville resident William Donahue replied to Head's comment writing that it was a somber day for hospital staff and the community.
