In 1990, Vietnamese women made up a third of patients within the hospital's maternity unit, leading to allegations of strained hospital resources and a subsequent scheme to transfer many pregnant refugees to Queen Elizabeth Hospital instead. By 1994, some Sha Tin residents voiced dissatisfaction that their hospital bore the weight of the refugee's medical needs, but then-hospital chief executive Alison Reid responded that the boat people comprised only five per cent of monthly visits to A & E and that the local population was "not being disadvantaged".
