Tufts Medical Center recorded a financial loss last year.
Tufts, a major Boston teaching hospital, lost $15.4 million on operations in the fiscal year ended Sept. 30, after an $8.6 million gain the previous year. Its chief executive, Dr. Michael Wagner, blamed one-time expenses.
Last winter's heavy snowfall, which made it difficult for patients to get to appointments, caused Tufts to lose revenue. Tufts also spent millions on consulting and legal fees when it was negotiating a merger with Boston Medical Center that was later called off. And Tufts spent more than $1 million to train staff and buy supplies to prepare for possible cases of Ebola. It also closed a unit to treat a patient incorrectly suspected of having Ebola.
