The Queen's Medical Center and St. Francis Healthcare officially came to an agreement on the sale of the former HMC facility in Ewa.
A spokesperson for Queen's says it will close on the deal this October and open in the fall of next year.
"The Queen's Medical Center is pleased to have the opportunity to serve the West Oahu campus," said Queen's Health Systems Communications Director Cedric Yamanaka.
Queen's says it will reopen the emergency room and plans to add more services to cater to the Leeward Oahu community.
Yamanaka says the hospital will invest more than $50 million in renovations and upgrades to the facility that's been vacant for more than eight months.
"We want to upgrade the imaging facilities there," said Yamanaka. "We want to upgrade the surgical suites and emergency services there."
When Hawaii Medical Center shut down its Liliha and Ewa facilities, more than a 1,000 people were laid off. Queen's says it will initially hire 400 positions and possibly more once the hospital is fully operational.
The city's Emergency Medical Services Director Dr. James Ireland says reopening the Ewa facility won't just impact Leeward Oahu but have an impact islandwide.
"It's not just going to impact the health care in West Oahu but the other hospitals as well because there's overcrowding at the other hospitals," said Dr. Ireland.
St. Francis says it couldn't comment on the details of the transaction.
But, it says once the sale is complete, it will not oversee the operations of the hospital but continue to run its hospice care and non-hospital related facilities islandwide.
According to its filing with the State Health Planning Agency, Queen's is spending more $73 million to buy and renovate the Ewa medical center.
