The Steward Health debacle may be nearing an end, but critics worry some of the arrangements in place to keep the chain's hospitals and 5,000-person doctors group up and running could trigger another fiasco. Some argue there were systemic problems related to private equity ownership and risky sale-leasebacks of properties that still loom over the surviving entities. Critics say the upshot is that 15 hospitals — located in Arizona, Florida, Louisiana, Ohio and Texas — are once again set up to face inflated rent charges and could ultimately fail.
