Struggling Tarpon Springs, FL-based Helen Ellis Memorial Hospital is seeking a partner to fund expansion of its cardiac care services. Helen Ellis chief executive Don Evans cautioned that going private is not an objective, but can't be ruled out as the hospital looks for a cash infusion. Squeezed by unpaid hospital bills, patients unable to pay for all but critical procedures, and the rising cost of charity care, the hospital could use a partner with cash to invest to help ensure its viability, Evans said.
