A REVIEW into security arrangements for sick Vietnamese boat people will be sought by Legislative Councillors this month in response to documented cases of Vietnamese using hospital visits to abscond. The move follows a report in yesterday's South China Morning Post which revealed a significant number of boat people were injecting themselves with contaminated fluids, including raw sewage, in desperate escape attempts. The Government was unable to say what plans it has to overcome the problem investigated by senior medical staff at the Prince of Wales Hospital in Sha Tin. Refugees Co-ordinator Brian Bresnihan is understood to be meeting key people involved in the transfer of Vietnamese to hospital. A government spokesman said last night the decisions to send boat people to hospitals were made by doctors at the detention centres solely on medical grounds. He said the Government was aware some detainees used their transfer to hospital as an opportunity to escape and that 'various government departments' were monitoring the situation. Six doctors found hundreds of cases where injuries were self-inflicted and dozens where detainees fled the hospital, some with intravenous drips, chest drains and urinary catheters still attached. In the latest Medical Journal of Australia , the Hong Kong doctors said it was 'distressing' that 57 per cent of patients admitted with self-inflicted injuries absconded. Most were patients from the Whitehead detention centre, which houses nearly 10,000 of the 21,000 boat people left in the territory. Security Panel deputy chairman Selina Chow Liang Shuk-yee said yesterday she would seek a full debate on the Vietnamese issue on November 29. She also planned to use the forum to ask for a review of the security issues raised in the medical journal. 'We need to get a sense of urgency back into the whole programme,' she said. The Government was faced with the dilemma of not wanting to impose strict 'prisoner-like' controls on the Vietnamese, not classified as prisoners, she said. 'If the Government comes down too hard, certain quarters of the community would react against it. 'The answer is to deport these people going to such drastic lengths as soon as possible. The problem is there are very few deportation flights these days,' Mrs Chow said. Security Panel chairman James To Kun-sun said: 'The world is watching very closely how we treat the Vietnamese in the camps.'
