Application Software That Can Prepare for Disasters Based on Patient-Participatory Evidence: K-DiPS: A Verification Report.

This paper describes the design and function of an application that enables vulnerable people to provide medical information for use in disasters, and presents the results of an initial test of its usability in Nankoku, Japan. The application consists of two parts: K-DiPS Solo, a smartphone app, and K-DiPS Online, a web application for disaster management by local governments. We asked vulnerable people or their family caregivers to enter medical information into the app on their smartphones and connected this information to a local government application as a demonstration of a disaster response solution that manages information. We targeted a group of 14 healthy older people. The user information that they entered into the app was stored in the cloud via the communication system of the mobile phone. A ledger of vulnerable people for use in the event of a disaster was automatically created on the web application using the information supplied by the individuals. Local government staff corrected the location information, if necessary, by dragging points plotted on a map. This disaster response solution was shown to connect individuals to government offices, and to enable a consistent flow of information from patient details to stocking of supplies, and for simulation, training, and response during disasters.

Factors related to preparedness for emergency hemodialysis in the event of a natural disaster.

ABSTRACT: This study aimed to explore patients' preparedness for emergency hemodialysis in the event of a natural disaster and to determine the factors affecting such preparedness.A cross-sectional study was conducted in undergoing hemodialysis at dialysis facilities in Sapporo, Hokkaido. The participants were a cohort of 256 outpatients aged 20 years or older, 186 (72.7%) were male, and the average age was 61.9 ±â€Š10.9 years. The participants were divided into those who had prepared for emergency dialysis treatment and those who had not. Cross tabulations were performed on the 2 groups using the following participant attributes: preparedness for dialysis during a disaster, knowledge of how to protect themselves during a disaster, and intention to dialyze and evacuate during a disaster, followed by binomial logistic regression analysis.Of the 256 study patients, 184 (71.9%) were not prepared for dialysis treatment. In logistic regression models, patients who were not prepared for dialysis treatment were found to have higher odds of being employed (odds ratio (OR): 2.469; 95% confidence interval (CI): 1.205-5.058), not being aware of disaster information acquisition methods in the event of a disaster (OR: 4.580, 95%; CI: 2.048-10.241), did not receive explanations on proper disaster response from dialysis facility staff (OR: 2.557, 95%; CI: 1.319-4.954), and believing that their family away from home would not be concerned about them (OR: 2.021; 95% CI: 1.062-3.847).Disaster preparedness in patients undergoing dialysis remain inadequate. Dialysis facilities need to strengthen their explanations of disaster response, particularly with regard to working, middle-aged people.

Development and Validation of an Interprofessional Collaboration Scale for Home Health Care for the Frail Elderly.

PURPOSE: The purpose of this study was to develop an interprofessional collaboration (IPC) scale for home health care for frail elderly. METHODS: The first items of the IPC scale included collaboration members' attitudes, awareness, motivation, team strength, communication, relationships, information, care recipients' interests, effects, development, utilization of social resources, contributions to the community, and crisis management. The subjects were 512 care managers who work in home care support offices across Japan. They manage interprofessional collaboration in home health care for frail elderly who need care at 65 years old and above. The scale's construct validity, internal consistency, the validity of known groups, concurrent validity, and test-retest reliability (193 subjects) were examined. RESULTS: The final IPC scale's items consisted of four factors (37 items): the strength of interprofessional teams (16), the management of collaborative systems (7), effects of collaboration (8), and communication (6). Four factors explained 58.6% of the total explained variance. The modified model fit of the scale achieved acceptable levels. The Cronbach's α coefficient for all items was .97. The sum of communication factor in the cities/wards group was lower than those in the towns/villages group. There were differences between the sum and each factor with different levels of ease to collaborate. The intraclass correlation coefficient for all items in the first and second assessments was .875. CONCLUSIONS: The validity and reliability of the IPC scale have been verified. This scale can be used to assess the IPC for home health care for frail elderly.

Predicting the Number of Suicides in Japan Using Internet Search Queries: Vector Autoregression Time Series Model.

BACKGROUND: The number of suicides in Japan increased during the COVID-19 pandemic. Predicting the number of suicides is important to take timely preventive measures. OBJECTIVE: This study aims to clarify whether the number of suicides can be predicted by suicide-related search queries used before searching for the keyword "suicide." METHODS: This study uses the infoveillance approach for suicide in Japan by search trends in search engines. The monthly number of suicides by gender, collected and published by the National Police Agency, was used as an outcome variable. The number of searches by gender with queries associated with "suicide" on "Yahoo! JAPAN Search" from January 2016 to December 2020 was used as a predictive variable. The following five phrases highly relevant to suicide were used as search terms before searching for the keyword "suicide" and extracted and used for analyses: "abuse"; "work, don't want to go"; "company, want to quit"; "divorce"; and "no money." The augmented Dickey-Fuller and Johansen tests were performed for the original series and to verify the existence of unit roots and cointegration for each variable, respectively. The vector autoregression model was applied to predict the number of suicides. The Breusch-Godfrey Lagrangian multiplier (BG-LM) test, autoregressive conditional heteroskedasticity Lagrangian multiplier (ARCH-LM) test, and Jarque-Bera (JB) test were used to confirm model convergence. In addition, a Granger causality test was performed for each predictive variable. RESULTS: In the original series, unit roots were found in the trend model, whereas in the first-order difference series, both men (minimum tau 3: -9.24; max tau 3: -5.38) and women (minimum tau 3: -9.24; max tau 3: -5.38) had no unit roots for all variables. In the Johansen test, a cointegration relationship was observed among several variables. The queries used in the converged models were "divorce" for men (BG-LM test: P=.55; ARCH-LM test: P=.63; JB test: P=.66) and "no money" for women (BG-LM test: P=.17; ARCH-LM test: P=.15; JB test: P=.10). In the Granger causality test for each variable, "divorce" was significant for both men (F104=3.29; P=.04) and women (F104=3.23; P=.04). CONCLUSIONS: The number of suicides can be predicted by search queries related to the keyword "suicide." Previous studies have reported that financial poverty and divorce are associated with suicide. The results of this study, in which search queries on "no money" and "divorce" predicted suicide, support the findings of previous studies. Further research on the economic poverty of women and those with complex problems is necessary.

Construction of an evacuee placement model for tsunami shelters considering physical distancing to prevent COVID-19 infection.

Earthquakes and tsunamis are expected to occur within the next 30 years along Japan's Nankai Trough. Existing disaster prevention plans and calculated evacuation capacities in the coastal areas that would be affected do not account for physical distancing in the context of COVID-19. Therefore, we developed a tsunami evacuation placement model incorporating physical distance guidelines for infection control and living space per person into calculations of evacuation center accommodation capacities in Aki City, Kochi Prefecture. Using available administrative, population, and tsunami inundation data, we counted and mapped evacuation centers in the estimated inundated area within three zones constructed for smooth evacuation using the ArcGIS software Build Balanced Zones Tool. We calculated the space per evacuee using the Sphere handbook standard of 3.5 m2 or double the Sphere standard at 7 m2 plus the recommended physical distance of 11 m2 per person. We then compared the results with planned capacities. A total of 27 shelters are located in the area projected to be inundated at depths of 0.3-10 m, and their planned capacity, 2 m2 for each evacuee, would accommodate 32.9% of Aki's population and result in 9639 unaccommodated evacuees. Allotting 14.5 m2 (living space) or 18 m2 (living space plus space to maintain physical distancing) would reduce accommodation capacities to 57.1% and 28.6% (12,133 and 12,371 unaccommodated evacuees, respectively). Given these accommodation shortages, we recommend that evacuation centers are set aside for vulnerable people and that alternative evacuation sites such as parking lots and mountain campsites are preplanned.

Model Comparisons of the Cost Effectiveness of Rubella Vaccination Method in Japanese Adults.

The number of rubella cases has increased in Japan, especially among adults. Rubella infection in pregnant females can lead to congenital rubella syndrome (CRS). The Japanese government is promoting vaccination to prevent CRS. This study performs a cost-effectiveness analysis of the following four methods: (1) females who wished to become pregnant and partners, with an antibody-titer test; (2) females only, with an antibody-titer test; (3) females and males, without an antibody-titer test; (4) females only, without an antibody-titer test. A decision tree model with a hypothetical cohort of 500 males and 500 females was used for the analysis, and the parameters were obtained from previous studies. The number of avoidances of CRS was defined as the effect. Compared to the case where methods were not implemented, the number of CRS cases that can be prevented by implementing the methods was 0.0115589 by (1) and (3) and 0.0147891 by (2) and (4). The cost effectiveness of (1) to (4) was 287,413,677 JPY, 135,050,529 JPY, 388,524,974 JPY, and 197,744,219 JPY, respectively (1 JPY = 0.00963247 USD). Method (2) was the most cost-effective and did not change by sensitivity analysis. We conclude that the vaccination for females only with an antibody-titer test is recommended.

Needs of Children with Neurodevelopmental Disorders and Geographic Location of Emergency Shelters Suitable for Vulnerable People during a Tsunami.

In the current study, we sought to identify special needs and safe evacuation conditions for children with neurodevelopmental disorders (CNDs) along Japan's tsunami-prone Pacific coast. A survey and spatial analysis were used to collect data of CNDs (n = 47) and their caregivers. Areas predicted to be flooded in a tsunami, as well as evacuation routes to emergency shelters for vulnerable people (ESVPs), were mapped using geographic information systems (GIS). Our results showed that five professional staff were needed to support 33 CNDs requiring 135.9 m2 of ESVP space. Critical safety factors were altitude, vertical evacuation, accessibility to ESVPs, and nonexistence of estuaries in the direction of evacuation. GIS-based spatial analysis and evacuation modeling for disaster preparedness and training plans that involve nurses are essential.

Interdisciplinary groups perform better than intradisciplinary groups in online group discussion activities.

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.

Residents living in communities with higher civic participation report higher self-rated health.

It has been shown that community-level social capital may affect residents' health. The present mixed ecological study assesses the evidence for an association between the community-level social capital and the individual level of self-rated health. The Hakui City Health Interview Survey targeted 15,242 people aged 40 years and older from 11 communities. Among them, 6578 residents responded to the questionnaire (response rate, 43.2%). We examined whether the community-level social capital (general trust, norm, and civic participation) was associated with the individual level of self-rated health. Overall, 1919 (29.1%) answers of self-rated poor health were identified. Community-level civic participation was negatively associated with poor self-rated health after adjusting for individual demographic factors, individual social capitals, and community-level economic status, whereas community-level general trust, and norm were not significant. The findings suggest the importance of fostering communities with high civic participation to reduce the poor health status of residents.

Effects of maintaining web-based diaries by caregivers on adherence to care regimens in preschoolers with asthma.

BACKGROUND: The objective of this pilot study was to assess the effects of maintaining web-based diaries by the caregivers of preschoolers with asthma on the adherence to asthma care regimens, the recognition of asthma symptoms, and their perceived levels of parenting stress, quality of life, and family functioning. DESIGN AND METHODS: The caregivers of preschoolers with asthma completed a 4-week web-based diary and received weekly emails that depicted their children's asthma symptoms. We compared asthma symptoms from before and after the intervention. We analyzed demographic data, such as the caregivers' age and education, and assessment scores from the Japanese Pediatric Asthma Control program (JPAC), Adherence with Asthma Management for Caregivers of Preschoolers (AAMCP), General Functioning subscale of the Family Assessment Device (GF-FAD), Parenting Stress Index Short Form (PSI-SF), and Quality of Life assessment scale for Caregivers of Asthmatic Children 24 (QOLCA-24). RESULTS: A total of 45 participants were included in the analyses. The mean scores depicting asthma control were significantly improved postintervention (pre: 12.29 ± 2.65; post: 13.02 ± 2.01; t = -2.15, p = .037). Mean AAMCP scores postintervention (52.13 ± 6.25) were significantly greater than before (49.78 ± 7.20; t = -3.07; p = .004). PRACTICE IMPLICATIONS: Adherence to asthma care and the recognition of asthma symptoms improved following the use of a web-based diary, making it a potential cost-effective intervention for asthma patients and their families.

Using GIS to simulate tsunami evacuation guidance signs for the hearing impaired.

The Nankai Trough in Japan has been identified as a geological feature that could cause extensive damage in the event of a major earthquake. In this study, we investigated the impact of effective guidance signs for hearing-impaired individuals requiring special care when escaping to a tsunami evacuation building (emergency evacuation location) using geographical information system (GIS) and viewshed analysis. We selected an area we considered would suffer severe damage following a major earthquake and tsunami; we identified difficulties in the provision of escape routes. Using GIS, we determined the time required for escape and tsunami arrival time if effective signs were installed; we undertook such analysis using the height data of buildings in the target area. With effectively installed guidance signs, the average required evacuation time was 36.88 minutes; without such signs (which is currently the case in the target area), the average time was 47.10 minutes: that would result in citizens getting caught by the tsunami. Installing effective guidance signs would allow hearing-impaired individuals to escape to an evacuation building before being hit by the tsunami.

[Regional Comparison on Recognition of Tasks for a Home Care System-Analysis of Medical Plans of 47 Prefectures by Text Mining and GIS].

A medical plan reflectsthe current state of a region. The purpose of thisres earch isto analyze medical plansby text mining and examine geographical features using a geographic information system. From the medical plans of 47 prefectures, nationwide, 6 regional divisions', and four age groups' text fileswere prepared. Further, wordswere extracted and subsequently, their relevance wasanalyzed. Additionally, we examined the geographical featuresus ing a color-dividing Japanese map by the word appearance rate of"Mitori"(end-of-life care), which is an important task. In the aggregate nationwide text files, 214,716 words were extracted. The top frequent words were medical care, home, support, nursing care, visit, medical treatment, and cooperation. In the co-occurrence network, medical care- home- nursing care- cooperation were connected with organization- construction. There was a link between human resources- training in Kanto and Kinki."Mitori"frequently occurred in areaswith a high aging rate, and there wasa human resources- training- securing connection in areas with a low aging rate. The frequency of"Mitori"was high in western Japan. The results suggested that collaboration between medical care and nursing care is emphasized in medical planning. Further,"Mitori"was emphasized in western Japan or areas with a high aging rate while human resourcesdevelopment wasemphas ized in areaswith a low aging rate.

[An Investigation into the Geographical Characteristics of Difficult Areas of Food Access in Mountainous Regions Using a Geographic Information System].

We performed this study with the aim of clarifying the geographical features of areas of difficult-to-access foods in mountainous regions, using GIS, altitude data, and future population projections. With QGIS, we mapped altitude data, future estimates of the old age population(mesh), and retail store data, and we extracted the altitude at the mesh center point. We also draw straight lines connecting the retail stores and the mesh center point. Meshes located in areas with high altitudes had significantly more meshes not occupied by humans than meshes located in low-lyingareas (p<0.01). At least 95% of the retail shops and mesh center points were separated by more than 500 meters, and thus are considered difficult to access. The number of non-residential areas increases in mountainous regions because of the sharp gradient and the long distance to retail stores. By visualizingusingGIS, future resources can be considered more realistically.

[Prediction of the Number of Home-Visit Care, Home-Visit Nursing Care, and Home-Visit Bathing Providers in 2025 in the Hokushinetsu Region Using a Mathematical Model and Examination of Geographical Features Using a Geographic Information System].

In this research, we constructed a prediction model for the number of service providers for home-visit care, home-visit nursing, and home-visit bathing by using the population in the Hokushinetsu region and the current number of providers, and considered the validity of the model. Using the model, we estimated the number of providers in 2025, and subsequently, visually confirmed geographical features using a geographic information system. The adjusted R2 value of the prediction model was 0.93 for home-visit care, 0.87 for home-visit nursing, and 0.63 for home-visit bathing providers. The number of providers for home-visit care, home-visit nursing, and home-visit bathing were estimated to decrease by 67%, 67%, and 28%, respectively. The colored map by the predicted number of providers suggested a significant decrease in home-visit care in Northern Nagano, home-visit nursing in Fukui-Reihoku region, and home-visit bathing in Middle Nagano.

[Investigation of the actual conditions of users of a home-visiting bathing service based on the long-term care insurance care ranking and factors affecting the judgment of bathing possibility].

AIM: In home-visiting bathing services (HVBs), a nurse's role is to evaluate the vital signs, judge bathing possibilities and provide treatment before/after bathing. There are no guidelines regarding specific physical criteria for judging the bathing possibility. However, the body condition of HVB users during bathing has not been investigated. Thus, the present study aimed to clarify users' actual conditions and the factors related to the judgment of the possibility of bathing. METHODS: An anonymous self-administered questionnaire survey of HVBs users was conducted by Company-A, which provides HVBs. Six hundred sixty responses were collected (response rate: 40.1%).We described the conditions of HVB users and used chi-squared tests and logistic regression analyses to confirm the factors, including the certified Long-term Care Insurance (LTCI) care rank, past medical history and physical conditions that were associated with aborted HVB experiences. RESULTS: The mean age of the care-recipients was 82.1±12.1 and 93.3% of the recipients had severe conditions, including conditions necessitation the use of medical equipment, pressure ulcers, and contracture. The logistic regression analysis showed that the LTCI-certified-care-rank, the presence of pain, and the need for treatment before bathing were significant factors. CONCLUSIONS: This study showed that users of HVBs not only had high LTCI-certified-care ranks, but that they also required pain management and pre-bathing treatment.

Disaster preparedness among families of older adults taking oral medications.

This study aimed to examine factors influencing disaster preparedness among families caring for older adults who take oral medications. Fifty-eight family caregivers completed anonymous self-administered questionnaires. Binomial logistic regression analysis with the storage of the care recipient's medications as the dependent variable revealed that caregivers' disaster-related information-seeking behavior (e.g., considering appropriate methods to collect such information), and recognition of disaster risks in their communities strongly influenced their storage of emergency medication.

Predictors of potentially harmful behaviour by family caregivers towards patients treated for behavioural and psychological symptoms of dementia in Japan.

BACKGROUND: Potentially harmful behaviour (PHB) by caregivers is detrimental to the physical and psychological well-being of care recipients. In Japan, few studies have investigated caregivers' PHB towards dementia patients. This study examined PHB in family caregivers of dementia patients with behavioural and psychological symptoms of dementia (BPSD) and identified factors related to PHB. METHODS: Following primary consultations at an elderly psychiatric patient department, we enrolled 133 pairs of dementia patients and their family caregivers. We assessed PHB using the Japanese version of the modified Conflict Tactics Scale. We defined the presence of PHB as two or more points (PHB frequency of 'sometimes' or more) on at least one indicator of the modified Conflict Tactics Scale. We investigated the prevalence of PHB in relation to the clinical characteristics of the patients and their family caregivers. We evaluated BPSD using the Neuropsychiatric Inventory and caregiver burden using the eight-item Japanese version of the Zarit Caregiver Burden Interview. RESULTS: Of the family caregivers, 48.9% showed PHB. Multivariate analysis identified the following association with PHB: caregiver's Zarit Caregiver Burden Interview total score (odds ratio [OR], 1.09 per unit increase; 95% confidence interval [95%CI], 1.02-1.16), and Neuropsychiatric Inventory scores for patient irritability (OR, 1.22 per unit increase; 95%CI, 1.06-1.40), appetite/eating disorders (OR, 1.41 per unit increase; 95%CI = 1.08-1.84) and daughters-in-law caregivers (OR, 0.17, 95%CI, 0.05-0.57). CONCLUSIONS: Specific BPSD symptoms could contribute to the expression of PHB. In addition to decreasing caregiver burden, more intensive treatment and care strategies are required to manage individual symptoms.

Tsunami evacuation simulation using geographic information systems for homecare recipients depending on electric devices.

Tsunamis cause direct damage to property and destroy infrastructure. In addition, power outages can lead to death, especially for patients who rely on medical equipment requiring a power supply. Recently, Nankai Trough Earthquakes have been predicted, and much effort has been put into developing countermeasures in Japan. Kochi City on Shikoku Island is expected to suffer in the event of a large tsunami. The present study identifies individuals living in Kochi who need evacuation assistance and depend on electrical medical devices, simulates evacuation behavior and inundation during a tsunami using a geographic information system (GIS), and considers the usefulness of such a GIS. We asked caregivers, including visiting nurses, to introduce us to homecare recipients who rely on a ventilator, an endotracheal suction device, or other medical devices requiring electric power. We received introductions to 52 homecare recipients. Using a GIS, we plotted the area of predicted inundation and the locations of homecare recipients, nursing stations, and welfare evacuation shelters. We predicted evacuation routes, and then analyzed the time difference between the time required for evacuation and tsunami arrival at a welfare evacuation shelter. To measure the effects of the main parameters, we conducted both one-way and multi-way sensitivity analysis. In the event of a tsunami, eight of the homecare recipients living in the forecasted inundation areas in Kochi may face delayed evacuation. Among homecare recipients facing a high possibility of escape delay, 95.2% lived more than 1,800 m from the nearest welfare evacuation shelter. We found that individual evacuation behavior can be simulated by specifying the residence of a homecare recipient and the evacuation route using a GIS.

[A Study on the Number of Offices for Home-Visit/Outpatient Day Long-Term Care in Noto Area, Based on Estimated Population - Analysis Using the Geographic Information System].

There has been a noticeable population decline in the Noto area. The Ministry of Land, Infrastructure, Transport and Tourism has determined the population size necessary for the establishment of daily living-related service businesses and, if the population falls below this, there is a possibility of businesses withdrawing from the area. In this research, we examine the number of home visit and daycare businesses established in the Noto area in 2025, using the geographic information system (GIS). The number of sites of businesses established was calculated using data published by the National Institute of Population and Social Security Research, and the Ministry of Land, Infrastructure, Transport and Tourism. Next, I depicted a buffer with a radius of 15 km from the establishment and confirmed the blank area of the service. Under the condition that the placement of sites is 80%, almost all the municipalities have exceeded the number of home visit care facilities and the number of daycare facilities. In the buffer analysis, blank areas were found in the north. To maintain these services, efforts by groups other than profit-oriented organizations are necessary, especially in the north of Noto. Route analysis by GIS and the consideration of population distribution and location of business establishment will be needed.

[Identifying the Regional Features in the Visiting Nursing Station Trade Area Using GIS].

In order to clarify the characteristics of the area where the visiting nursing station is located, we conducted a study to identify the regional characteristics of the visiting nursing station in Ishikawa Prefecture, using geographical information system(GIS). We mapped the elderly population, aging rate, and location data for the visiting nursing station using QGIS, and created trade areas(Voronoi diagrams). The aging rate for each trade area is 22.4%(min 8.8% to max 44.6%), about 5 times. The difference in area is about 850 times as large as the central value of 9.2 km2(min 0.5 km2 to max 423.2 km2). In addition, there was a tendency for stations with a large trade area to have a higher aging rate than that of smaller stations. Understanding the characteristics of the area surrounding visiting nursing stations using GIS facilitates the clarification of potential needs and opportunities for providing visiting nursing services that are suitable for each area.
