ABSTRACT.The purpose of the study was to find a practical applicable method for estimating risk of accidents among nursing home patients by localizing specified risk factors and recording accidents during a period of one year. During 1987‐January‐15 to 1988‐January‐14, a total of 153 accidents happened to 23 men and 76 women among 335 admitted patients. The strongest accident predictors suggested by a logistic regression procedure were: impaired balance, walking with device or human assistance, drugs influencing the central nervous system, dizziness and poor night‐time sleep.The conclusion is reached that it will probably be possible to reduce accidents in the institutionalized elderly by education of staff, identification of risk patients, individual nursing planning and mea
