Although patient falls have been described in the healthcare literature for more 60 years, and many risk assessment tools have been developed, the rate of falls in hospitals in Japan has remained unchanged for the last 8 years. A previous study reported that about 50% of patients in rehabilitation estimated their fall risk lower than that estimated by their nurses. We believe that patients in rehabilitation tend to overestimate their ability to perform ADLs. Aim: To identify discrepancies between patients’ and nurses’ estimates of patients’ ability to perform activities of daily living (ADL) and clarify any relationship between the discrepancies and patient falls. Methods: Participants comprised 82 patients (42 men) admitted to a rehabilitation unit in Osaka, Japan from July to December of 2017. Patients and their nurses answered the same questionnaire about patients’ ability to perform ADL. The questionnaire was developed based on the Functional Independence Measure (FIM) and administered at admission, at 1 month after admission, and at discharge. Participants were classified into the overestimating group and the accurately estimating/underestimating group, and groups were compared using Wilcoxon rank-sum tests. Results: The mean age of participants was 76.4 years. At admission, approximately 72% of participants estimated their own ability to perform ADL higher than did the nurses. The percentage of overestimating participants dropped to 30% at discharge. Fifteen of the participants experienced a fall;all were in the overestimating group. The ADL Discrepancy and fall-assessment scores for these 15 participants were significantly higher than those of other participants. Conclusions: There are discrepancies between patients’ and nurses’ estimates of patients’ ability to perform ADL and had important significance for assessing their risk of fall. And minimizing the discrepancy may support the prevention of falls.展开更多

Sad confirmation of this statement unexpectedly has come from the nuclear power plant accident in Fukushima which occurred while this paper was finalized. Two strategies to comply with the task of impact and risk assessment in extended regions like Central Europe or the Balkans are described. The first one is characterized by application of a single model system to an extended domain. The other one is based on the combined application of several chemical transport models designed for the use in various sub-domains in the region under consideration. Advantages and disadvantages exist for both approaches. For instance, the single model strategy allows unified and harmonized assessment of risks in a larger region, whereas the combined model strategy may pro-vide faster and locally more specific response in emergency cases. The single model approach is treated exploiting applications of the EURAD model system. The combined model approach is a novel way of joint use of chemical transport model systems developed for the Balkans. The models are described and the accuracy of simulations carried out with them is briefly demonstrated by comparison of simulated and observed concentrations of air pollutants. Applications regarding the search of sources for high pollution events and the assessment of risks through known sources are exem-plarily discussed.展开更多
