CHICAGO, Nov 3 (Reuters) - Hospital operator Tenet Healthcare Corp (THC.N: Quote, Profile, Research) reported a small quarterly net loss on Tuesday, saying rising unemployment has had less of an impact on the company than was expected.

Tenet, the third-largest hospital chain behind privately held HCA Inc [HCA.UL] and Community Health Systems Inc (CYH.N: Quote, Profile, Research), reported a net loss of $3 million, or 1 cent a share, for the third quarter, compared with net income of $104 million, or 22 cents a share, a year earlier, when pretax gains on sales of investments boosted results.

Dallas-based Tenet said its adjusted earnings before interest, tax, depreciation and amortization rose 50 percent to $240 million, helped by cost-reduction initiatives.

Tenet raised its forecast for full-year adjusted EBITDA by $25 million to a new range of $925 million to $975 million. It reduced its forecast for net income to a range of $66 million to $130 million from a prior forecast of $76 million to $141 million.
