In the course of the investigation, "60 Minutes" interviewed 100 current and former employees of HMA and uncovered some disturbing trends. The story was the same in HMA facilities all over the country; HMA exerted pressure on emergency room doctors to admit patients who didn't need to be admitted, according to the report. In some cases, doctors claimed that HMA set quotas on the percentage of patients that had to be admitted through the ER. Furthermore, physicians interviewed claimed that HMA had a computer program that automatically scheduled tests on patients based on their age and condition whether they needed the tests or not. And we wonder why our health-care system is so expensive?
