THE taskforce probing the Hong Kong Sanatorium dialysis blunder yesterday drew up a list of dozens of personnel to interview, but admitted it had no power to force them to talk. Members mapped out an agenda for the inquiry during their first meeting, after being appointed by the hospital where three kidney patients died after contaminated fluid was administered during treatment on Thursday. The three-member taskforce, headed by University of Hong Kong Professor Lai Kar-neng, met hospital chiefs, including deputy medical superintendents Dr Walton Li Wai-tat and Dr Tsao Yen-chow. The report, to be submitted to the Health Department in two weeks, will list the causes of the mistake, look at emergency measures adopted after the incident and pinpoint ways to prevent a repetition of the tragedy. But the inquiry will not apportion blame. Hospital Authority deputy director Dr Ko Wing-man said it would take note of the report to prevent such incidents occurring at the dozen public hospitals with similar dialysis devices. Professor Lai said the team planned to interview hospital administrators, medical personnel on duty on Thursday and engineers sent from Gambro China to repair a central water treatment machine which purified tap water being supplied to the haemodialysis device. They will be asked to report in detail on what happened and the emergency measures adopted when the six patients affected started convulsing and vomiting. The three surviving kidney patients and relatives of the three dead will also be interviewed. But taskforce member and medical constituency legislator Dr Leong Che-hung admitted it had no power to make anyone attend interviews. 'I think we can only appeal to them to try their best to co-operate with us. They have the right to decide whether to say anything,' Dr Leong said. 'We don't have any statutory powers. But any parties should be working for the benefit of the patients.' Dr Leong said the team hoped to complete its interviews in one or two days. Dr Li said all dialysis nurses at the sanatorium were well-trained. The hospital would address the issue of compensation after determining where the responsibility lay, he said. Meanwhile, one of the three survivors, Wong Ah-kiu, 71, was discharged yesterday while Yim Cho-yiu, 82, and Cheung Siu-chun, 60, remained in stable condition. Ms Wong's son said his mother had been attended by two nurses when she received dialysis yesterday. Previously, three nurses and two assistants looked after seven patients at a time.
