BOISE, Idaho (AP) — Trial records from an anti-trust lawsuit between two Boise hospitals and the Federal Trade Commission show hundreds of documents are being hidden from public view under laws designed to protect trade secrets.

The Idaho Statesman reports that the documents, marked "Attorney's Eyes Only," reveal details of St. Luke's Health System's purchase of the Saltzer Medical Group in Nampa as well as compensation packages.

The purchase is at the heart of the lawsuit from rival Saint Alphonsus Regional Medical Center and the FTC against St. Luke's. Saint Alphonsus and the FTC say the purchase gives St. Luke's an unfair market share and will raise health care prices; St. Luke's counters that the purchase gives patients better care and will allow the company to create lower-cost options for consumers.
