Denver-based kidney care giant DaVita HealthCare Partners Inc. announced Wednesday it has acquired Colorado Springs Health Partners, the largest health care practice in Colorado Springs - a deal that could change the face of local health care. Terms of the deal, which is expected to be completed by year's end, were not disclosed. Colorado Springs Health Partners is owned by 76 of its 114 doctors, and all 76 approved the deal, said Deborah Chandler, CEO of the 68-year-old practice. The acquisition isn't expected to mean many changes for CSHP's 110,000 patients, since DaVita will keep the practice's management team and retain its more than 600 employees.
