Nurses' knowledge was significantly associated with age (group 30 - 40 years old had better score compared to group > 40 years old), training mode (full-time training group had better knowledge compared to group part-time training), level of education (postgraduation and bachelor of Nursing Science group had greater knowledge score compared to group with lower training level). Nurses having trained at medical school or having continuous training on fall prevention had better knowledge than those who did not take part in fall prevention training.
