【Objective】This study aimed to clarify the relationship between the mode of admission（planned/unplanned） and incidence of falls in an acute care hospital.

【Methods】 The participants included 10,778 inpatients admitted to the Asa Citizens Hospital between April 2021 and December 2021. Using our hospital’s incident report database, we recruited patients with falls in the hospital. We compared the incidence of falls in planned and unplanned inpatients.

【Results】There were 6,313 and 4,465 planned and unplanned inpatients, respectively. Of the 314 patients who suffered falls（2.9％）, 131（2.1％）and 183（4.1％）were planned and unplanned inpatients, respectively. The relative risk of falls in unplanned inpatients was 2.0 times higher than that in planned inpatients. The incidence of falls tended to increase in the elderly group in both the planned and unplanned hospitalizations. The incidence of falls was higher in unplanned inpatients than in planned inpatients, and the relative risk of falls was highest in the younger group（aged <65 years, 3.0 times）, followed by the early elderly group（aged 65 –74, 2.1 times）and the late elderly group（aged ≥75, 1.5 times）.

【Conclusions】 We clarified that the incidence of falls in acute care hospitals was higher in unplanned inpatients than in planned inpatients.

【Purpose】This study focuses on clearance related to tripping to identify the gait features of fallers corresponding to the minimum and maximum clearances during the swing phase, as well as the difference in the foot clearance measurement positions.

【Methods】 We included 26 non-fallers（13 females with an average age of 69.4 ± 3.2 years）and 23 fallers（12 females with an average age of 67.7 ± 2.6 years）in community-dwelling older adults. The subjects performed a walking task at a normal speed. The maximum and minimum clearances during the swing phase were recorded using a motion capture system and the ground reaction force. The study used 11 reflective markers, placed along a straight line, from the heel to the head of the third metatarsal bone, as the foot clearance measurement positions. The effect sizes were calculated using Cohen’s d.

【Results】For all conditions of the foot clearance measurement positions, the maximum clearance in fallers during the swing phase was significantly smaller than those in non-fallers. However, under most conditions, the minimum clearance in fallers during the swing phase was significantly smaller than those in non-fallers. The effect sizes of the maximum clearances（0.68 –0.84 [medium–large]）were greater than those of the minimum clearances （0.53 –0.54 [medium]）. Further, the effect size of the maximum clearance in the toe position（0.84 [large]）was greater than that in the heel position（0.68 [medium]）.

【Conclusions】 We identified the gait features of fallers to obtain clearance related to tripping. The results showed that one must focus on the“maximum”clearance of the “toe position”during the swing phase to identify older adults with higher fall risk.

【Objective】The purpose of this study was to clarify the relationship between the biosocial rhythm, living function, and cognitive function and the fall-related self-efficacy（fall-SE）in community-dwelling older adults.

【Methods】 The participants included 52 older adults over 65 years of age. Fall-SE was measured using the Falls Efficacy Scale-International（FES-I）. The living status was estimated using a biosocial rhythm questionnaire and the Kihon checklist（KCL）. Executive function, estimated error on functional reach test, and estimated error on two-step test were used for cognitive function evaluation. Multiple regression analysis was performed to examine the factors related to fall-SE. The dependent variable was the FES-I score. The independent variables included the total score and scores of all subitems in the biosocial rhythm questionnaire and the total score and scores of all subitems in the KCL or each cognitive function evaluation.

【Results and Discussion】The mean age of participants was 75.3±6.5 years.The score of sleep quality in the biosocial rhythm questionnaire showed a significant negative association with FES-I（B =－2.148, 95% CI：－3.676, −0.620, p= 0.007）. The score of housebound in the KCL also showed a significant positive association with FES-I （B = 6.191, 95% CI：0.950, 11.433, p= 0.022）. Cognitive function showed no association with FES-I. Therefore, biosocial rhythm and living function were related to fall-SE. These results suggest that it is necessary to focus on sleep quality and housebound for examining the factors related to fall-SE.

【Conclusions】 In this study, we showed suggest that it is necessary to have a comprehensive view of not only the physical function but also the biosocial rhythm and life function in order to understand the fall-SE of community dwelling older adults.

【Objective】The purpose of this study was to clarify the actual conditions of fall prevention for the elderly with dementia practiced by nurses in convalescent rehabilitation wards.

【Methods】 According to the public information on the homepage of The Association of Rehabilitation Wards， research request was mailed to the nursing director of 124 hospital in the Kinki region，with more than 50 beds in the rehabilitation ward. Of these, 411 full-time nurses with more than one year of experience in convalescent rehabilitation wards at 23 hospitals who gave their consent were surveyed by mail using an anonymous self administered questionnaire.

【Results and Discussion】Overall，the number of valid responses was 148（36.0%）. Among the items related to assessment, approximately 70 % or more of nurses answered that they were “implementing” fall assessments in half of the items. However, 39.9 %（59 nurses）answered that they were not implementing the “A_3. evaluate the stable situation of life as your original lifestyle”. In addition, in analyzing the items related to care plans and practices, 37.2 %（55 nurses）were “not implementing” “B_2. acceleration of the process of adjustment to the living environment to prevent falls caused by the unfamiliar environment immediately after admission to”. It was revealed. Moreover we believe that utilizing manuals for fall prevention and devising initiatives, such as personnel utilization systems, would help in the prevention of falls.
