Tenet Healthcare, the nation's third-largest hospital company, reported fourth-quarter profit that missed analysts' estimates on higher costs for uninsured patients amid a flu outbreak. Earnings excluding one-time items were 52 cents a share, the Dallas-based company said Tuesday in a statement. The result was 15 cents lower than the average of 19 analysts' estimates compiled by Bloomberg. Revenue climbed 7.3 percent to $2.33 billion.
