[Purpose] To investigate the risk factor in places where falls occurred in a long-term care health facility.[Subjects] 115 residents in a long-term care health facility with a history of falls.[Methods] A retrospective survey of accident reports was conducted. With the places where falls occurred (residents' rooms, corridors, toilets, rehabilitation rooms, bathrooms) as the dependent variables, and necessity of supervision and assistance with ADL, wheelchair use, medication use, comprehension ability, impaired vision, and pain as the independent variables, logistic regression analysis was conducted.[Results] The total number of falls was 220: 135 in residents' rooms, 25 in corridors, 26 in toilets, 3 in rehabilitation rooms, and 2 in bathrooms. The risk factor of falls were determined as wheelchair use and pain in residents' rooms, and not being a wheelchair user in corridors.[Conclusion] The implementation of interventions is necessary considering the risk factor determined for residents' rooms and corridors.
