RESUMEN

When large earthquakes occur over wide areas, in addition to damage to medical facilities, the disaster response capabilities of local governments are severely compromised. There is a very high possibility that the supply-demand balance of medicines will collapse within the disaster area, and that appropriate supplies of medicines will not be provided to disaster victims. Therefore, it is important to estimate in advance the quantity of pharmaceuticals that may be needed during disasters. In this study, the purpose is to clarify the quantity and quality of pharmaceuticals used by chronically ill patients by using Japanese National Health Insurance data regarding the issues mentioned above. The methodology used was to extract the status of pharmaceutical prescriptions based on receipt information from National Health Insurance data for Hakui, Ishikawa Prefecture, a small regional city in Japan, as the analysis target area. Through the analysis in this study, the quantity and quality of medicines supplied to chronically ill patients in Hakui, Ishikawa Prefecture, were clarified on a town-by-town basis.

RESUMEN

Online classes have been provided for health-care pre-licensure learners during the novel coronavirus disease 2019 pandemic. The purpose of this study was to evaluate the utility of online group work in interprofessional education. A total of 209 students were assigned to 50 groups (18 medical student groups, 13 nursing student groups, and 19 mixed medical/nursing student groups). Learners performed group work during the orientation for the course, which was hosted using an online video conferencing system. The learners first performed the activity individually (10 min) and then engaged in a group discussion to reach consensus on their answers (30 min). We calculated the scores before and after the group discussion and shared the results with the students. Scores were improved after the group discussion (mean ± SEM, 23.7 ± 0.9) compared with before (37.3 ± 1.3) (P < .0001). Lower scores after the group discussion, which indicated the effect of the group discussion on making better decisions, were observed most in the mixed medical/nursing student groups, followed by the nursing student and medical student groups. We noted only 3 groups in which the group discussion showed a negative effect on decision-making: all 3 of these groups were mixed (3 of 19 groups; 16%). These data demonstrated the power of group discussion for solving tasks when the participants' professional fields were mixed. However, the small size of the interdisciplinary groups might have resulted in less effective discussion, which might be due in part to psychological barriers arising from professional differences. Online group work is effective for facilitating discussion and building consensus about decisions in interprofessional education for medical and nursing students. Potential psychological barriers may exist in about 16% of mixed group students at the start, which should be kept in mind by instructors.

RESUMEN

AIM: The purpose of this study is to describe the influences of lower limb edema on the daily lives of elderly individuals in elderly day care to describe the necessity of care for lower limb edema. METHODS: Semi-structured interviews based on a quality of life questionnaire for limb lymphedema were conducted. Two types of text mining analysis methods were used: a frequent word analysis and a content analysis. The edema severity was graded on a scale of 0 to 3, and the sum of the numerical values of the grades for each person was defined as the pitting score. RESULTS: The seven participants had a mean age of 83.4 ± 4.6 years (mean ± SD). The pitting scores ranged from 1 to 25 in the participants. The words "think" (389 times), "walk" (136 times), and "put on" (135 times) were extracted frequently. The content analysis focused on the words "walk" and "put on." The participants complained of difficulty walking, pain, and numbness when walking, weakness of their lower limbs, difficulty putting on shoes, restrictions on shoe types, and difficulty finding shoes. CONCLUSIONS: These results demonstrate that elderly individuals experienced troubles during their daily lives caused by lower limb edema, which highlights the necessity of symptom management. Active interventions for edema by nurses are necessary to improve quality of life in elderly individuals.

RESUMEN

BACKGROUND: Both cigarette smoking and diabetes mellitus are well-established risk factors for development of dementia. However, the interaction between smoking and diabetes is yet unknown. OBJECTIVE: In this study, we clarify association between smoking, diabetes, and dementia risk in older adults. METHODS: Participants in this study included community residents aged 65 years and older who had participated in a health checkup in 2006, followed for 10 years (n = 9,403) and had long-term care insurance information data. Furthermore, the risk estimates of smoking status and diabetes diagnosis on dementia adjusted for the competing risk of death prior to dementia were analyzed. RESULTS: During follow-up, 2,647 participants developed dementia. The smoking status-diabetes interaction on development of dementia was statistically significant (p≤0.001). Among those patients exposed to both factors, 17% of risk of development of dementia was attributable to the interaction of these factors. Current smokers with diabetes had significantly greater risks of development of dementia than never smokers without diabetes (reference): multivariable-adjusted risk of dementia in current smokers without diabetes (subdistribution hazard ratio [sHR], 1.25; 95% confidence interval [CI], 1.05-1.48); never smokers with diabetes (1.31, 1.16-1.47); and current smokers with diabetes (1.86, 1.39-2.48). However, no such association was noted for former smokers with and without diabetes. CONCLUSIONS: Current smoking, but not former smoking, was associated with increased risk of development of dementia in older adults with and without diabetes. Moreover, the synergistic effect of current smoking and diabetes on dementia was noted.

RESUMEN

The 2013 Partial Amendment of the Disaster Countermeasures Basic Law mandated that a roster of vulnerable persons during disasters be created, and further development of evacuation support is expected. In this study, the number of vulnerable people living in target analytical areas are identified in terms of neighborhood units by using the National Health Insurance Database to create a realistic and efficient evacuation support plan. Later, after considering the "vulnerability" of an area to earthquake disaster damage, a quantitative evaluation of the state of the disaster is performed using a principle component analysis that further divided the analytical target areas into neighborhood units to make a detailed determination of the number of disaster-vulnerable persons, the severity of the disaster, etc. The results of the disaster evaluation performed after considering the vulnerability of an area are that 628 disaster-vulnerable persons live in areas with a relatively higher disaster evaluation value.
