The effect of the 2018 Japan Floods on cognitive decline among long-term care insurance users in Japan: a retrospective cohort study

BACKGROUND@#The July 2018 Japan Floods caused enormous damage to western Japan. Such disasters can especially impact elderly persons. Research has shown that natural disasters exacerbated a decline in cognitive function, but to date, there have been no studies examining the effects of this disaster on the elderly. The object of this study was to reveal the effect of this disaster in terms of cognitive decline among the elderly.@*METHODS@#Study participants were certified users of the long-term care insurance (LTCI) system in Hiroshima, Okayama, and Ehime prefectures from May 2018 to June 2018. The observation period was from July 2018 to December 2018. Our primary outcome was cognitive decline after the disaster using a dementia symptomatology assessment. In addition to a crude model, a multivariate Cox proportional hazards model was used to assess the cognitive decline of victims, adjusting for age classification, gender, the level of dementia scale before the disaster occurred, residential environment, whether a participant used facilities shut down after the disaster, and population density. After we confirmed that the interaction term between victims and residential environment was statistically significant, we stratified them for the analysis.@*RESULTS@#The total number of participants was 264,614. Victims accounted for 1.10% of the total participants (n = 2,908). For the Cox proportional hazards model, the hazard ratio of the victims was 1.18 (95% confidential interval (CI): 1.05-1.32) in the crude model and 1.12 (95% CI: 1.00-1.26) in the adjusted model. After being stratified by residential environment, the hazard ratio of home victims was 1.20 (95% CI: 1.06-1.36) and the hazard ratio of facility victims was 0.89 (95% CI: 0.67-1.17).@*CONCLUSIONS@#This study showed that elderly living at home during the 2018 Japan Floods were at risk for cognitive decline. Medical providers, care providers, and local governments should establish a system to check on the cognitive function of elderly victims and provide necessary care support.

The Role of On-Call Duty at the Tenri Hospital Emergency Department in Clinical Training in a General Outpatient Setting / 医学教育

Objective: To investigate the role of postgraduate clinical training at the emergency department of Tenri Hospital in teaching the diagnostic process in the general outpatient department.<BR>Method: Patients seen by 11 first-year residents at the emergency department were consecutively registered with summary sheets. Further information was added, and an analysis was performed of: 1) the distribution of chief complaints in the emergency and general outpatient departments and 2) initial diagnoses and the diagnostic process in the emergency department and the final diagnoses.<BR>Results: The distributions of chief complaints in 89 cases in the emergency department and in 183 cases in the general outpatient department were closely correlated (p=0.0016). Diagnoses in the emergency department were correct in 58% of cases. Treatment was incorrect in 3% of cases.<BR>Conclusion: The distributions of chief complaints in the emergency and general outpatient departments were similar. In our hospital the emergency department plays a major role in postgraduate clinical training by teaching the diagnostic process for the general outpatient department. Clinical management, including decision making for further tests and consultation, in the emergency department by first year residents did lead to any major adverse events.
