Collaboration talks between Kapiolani Health Care System and Queen's Health System have ended without a decision to share resources or merge.
Issues including board structure and leadership, management concerns, equity, and overall timing couldn't be resolved, according to Roger Drue, president and chief executive officer at Kapiolani.
The Hawaii systems' boards didn't release details on issues that couldn't be ironed out.
"Because these are both large and complex organizations, those issues were various....We have both very diverse cultures and very different management cultures," a Kapiolani spokeswoman said.
Executives of the systems said last April they wanted to determine if collaboration would improve both organizations' quality of services and broaden community access, as well as better control healthcare costs.
Kapiolani Health Care is the parent organization of 240-bed Kapiolani Medical Center for Women and Children in Honolulu, and 116-bed Kapiolani Medical Center at Pali Momi on Oahu.
Queen's, Hawaii's largest private healthcare company, operates the state's largest private hospital, 566-bed Queen's Medical Center in Honolulu, as well as 14 other subsidiaries.
