The consequences of hospital errors can be devastating for patients. And perhaps few have suffered more from hospital mistakes than one Ohio woman whose ordeal began with a colonoscopy in August 2010. The procedure was supposed to be routine -- a simple outpatient colonoscopy scheduled with a clinic specialist in Westlake by her primary care physician. But the day after the medical procedure, the woman fell ill while at work and had to be picked up by her husband. Her condition became progressively worse, and she was rushed to the Cleveland Clinic -- affiliated Lakewood Hospital, where she was wheeled into emergency surgery.
