Comparison of document-based and on-site inspections of hospitals based on medical law: A case report from Osaka City during the COVID-19 pandemic

Objectives On-site inspections of hospitals were conducted in Osaka City during fiscal years 2018 and 2019, whereas document-based inspections were performed during the COVID-19 pandemic in fiscal year 2021. This case report aimed to compare the outcomes of these two methods and provide a good indication of the method that should be selected in case of a pandemic.Methods For on-site inspections, documents, including checklists, were sent to 351 hospitals from the Osaka City Public Health Office, and responses from each hospital were returned. On-site inspections were conducted, and the written instructions that indicated inadequate aspects and guidance were mailed to hospitals.For document-based inspections, documents were sent to 176 hospitals, and responses were returned. For hospitals that answered "incomplete" regarding the categories of medical safety management systems and hospital-acquired infection control, public health physicians called to confirm and instruct their inadequate responses, and the same step as the on-site inspection was executed. We compared and examined the outcomes of the on-site and document-based inspections.Results In the on-site inspections, 12 of the 351 hospitals (3.4%) were recognized as inadequate because of a shortage of healthcare workers. In the document-based inspections, eight out of 176 hospitals (4.5%) were identified, and there was no significant difference.Regarding the medical safety management system, 95 of the 351 hospitals (27.1%) on on-site inspection and 21 of the 176 hospitals (11.9%) on document-based inspection received written instructions. The proportion of hospitals that received written instructions was significantly higher for on-site inspections than for document-based inspections (P < 0.001).For hospital-acquired infection control, 65 of 351 hospitals (18.6%) on on-site inspection and 17 of 176 hospitals (9.7%) on document-based inspection got written instructions. The proportion of hospitals that received written instructions was significantly higher for on-site inspections than document-based inspections (P = 0.007).Conclusion Document-based inspection can easily unify the guiding criteria with fewer public health physicians. However, because of the limited amount of information available without checking the documents retained in hospitals, it is difficult to monitor the matters that need instructions. Thus, on-site inspection is preferable. However, if onsite inspection is difficult, inspection combined with online methods should be considered.

CORRELATION BETWEEN MATERNAL EDUCATION AND EMPLOYMENT STATUS WITH EXCLUSIVE BREASTFEEDING HISTORY

Background: In 2022, the sole lactation coverage rate in Indonesia was recorded at 67.96%. According to the East Java Provincial Health Office, 67.54% of women in the province of East Java were exclusively nursing in 2022. This falls very short of the 80% goal set by the Republic of Indonesia's Ministry of Health in 2020. Infants require breast milk and adequate nutrition to increase their nutrient levels during growth. Exclusive breastfeeding cannot be optimally provided due to various factors such as maternal education history, which influences the mother's limited knowledge about the importance of exclusive breastfeeding maternal employment. These two factors affect the provision of exclusive breastfeeding to infants. Given the foregoing context, the study's goal was to discover how a mother's job description affected her history of exclusive breastfeeding. Method: The study employed a cross-sectional strategy and a quantitative, analytical observational design. Purposive sampling was used to choose 111 participants for the study, who were all mothers with infants between the ages of 6 and 12 months. The study will be carried out in Madiun City's Public health Service Tawangrejo East Java, Indonesia. operational region. This study was conducted from February to April 2024. Data collection utilizes questionnaires. The chi-square test was used to analyze the data. Result: The p-value is 0.03 or less than 0.05, showing that the history of exclusive breastfeeding was significantly correlated with the mother's employment position and educational attainment. Mothers with a history of exclusive breastfeeding have a poor association between their employment status and education, as indicated by their correlation coefficient (R) value of 0.362. Conclusion : there is a relationship between education, employment level, and history of exclusive breastfeeding at the Tawangrejo Community Health Center in Madiun, East Java, Indonesia.

Qualitative exploration of determinants of active mobility and social participation in Urban neighborhoods: individual perceptions over objective factors?

BackgroundUrban neighborhood environments play an important role in facilitating or hindering residents to engage in active mobility and social participation. However, while there is much quantitative research, in-depth knowledge that contextualizes residents’ subjective perceptions of barriers and facilitators of active mobility and social participation is still insufficient. Therefore, a qualitative approach was used to collect subjectively perceived barriers and facilitators of active mobility and social participation of residents from different neighborhoods with objectively determined high vs. low walkability. Furthermore, to better understand (non) concordance of objective environmental characterizations and actual levels of behavior, low and high walkability neighborhood-specific barriers, proposed improvements, and particularities that determine (non) engagement in active mobility and social participation were explored.MethodsThree focus groups (N = 6, N = 6, and N = 5) with 17 participants (7 women, 10 men) aged 21–64 (mean age 43.4 ± 14,6 years) were conducted utilizing a pre-structured interview guideline. Participants lived in 11 different neighborhoods with either high or low objectively determined walkability. The focus groups were transcribed verbatim, followed by a thematic analysis of the content with deductive and inductive code categories, utilizing the MAXQDA software.ResultsNotable was the consensus of many perceived barriers and facilitators of active mobility and social participation along with their assignability to the same context (points-of-interest, infrastructure; safety, communication, community; topography, physical compositions, weather, aesthetics; personal / individual attitudes, influences, evaluations). Another main finding was that high and low walkability neighborhood-specific particularities were revealed that are in contrast to some objective characterizations of walkability: For example, too high density can inhibit active mobility, and too many options can inhibit social participation.ConclusionsThe consensus of many barriers and facilitators of active mobility and social participation suggests that valuable synergies could be created by coordinating interventions aiming to promote both active mobility and social participation in urban neighborhoods. Also, considering subjective perceptions of residents helps to identify neighborhood-specific factors that determine (non) engagement in active mobility and social participation. The findings can help city planners and public health officials improve the promotion of active mobility and social participation in the creation of health-enhancing urban neighborhoods.

Impact of border control measures on public health center operations and staffing at international airports during the emergence of the SARS-CoV-2 B.1.1.529 (Omicron) variant of concern

Objective Ota City, located in southeastern Tokyo, including Haneda Tokyo International Airport, has numerous scattered lodging facilities. Shortly after the first case of SARS-CoV-2 B.1.1.529 (Omicron) variant was reported abroad, the Japanese government strengthened border control measures, including quarantine procedures and public health official involvement, for incoming travelers. This study aims to propose effective and efficient border control measures to prevent future outbreaks of emerging and re-emerging infectious diseases.Methods Border control measures implemented between November 2021 and mid-January 2022 were analyzed from three perspectives: chronological changes in government notifications, the situation of in-flight contacts and Omicron cases, and the support system for coronavirus-disease 2019 control department of the Ota City Public Health Center. Additionally, a questionnaire survey was conducted among public health centers with jurisdiction over the top four international airports. This survey aimed to assess the effectiveness of the support system, evaluate cooperation with related organizations, identify common issues faced by public health concerns, and gather suggestions for improvements in future border control measures.Results The definition and treatment of in-flight contacts of Omicron-positive individuals were initially outlined on November 30, 2021, and underwent frequent revisions until January 14, 2022. Between December 1, 2021, and January 12, 2022, only one Omicron case was identified among the 470 tests conducted on in-flight contacts. However, out of 136 additional domestic specimens collected (including 57 positives for genetic analysis), 40 were confirmed Omicron positive. The results of the questionnaire survey across the four public health centers largely mirrored the issues and suggestions identified by Ota City officials. A significant portion of these issues arose from managing temporary non-Japanese residents staying near international airports.Conclusion Border control measures should be implemented to delay the domestic spread of the virus. In this reason, it is crucial to avoid placing an undue burden on public health officials responsible for handling domestic infections. Since response policies and target definitions may need to adapt to unknown pathogens, they may be changed frequently, baffling the officials; however, a system for collecting real-time data from frontline sites and making evidence-based decisions is essential. Additionally, deploying liaisons from national and prefectural governments to focal points of emergency response would strengthen the support system by promoting unified instructions and information sharing.

Salt reduction attempts in workers after specific food service facility guidance provided by a public health center: A case study at a worksite in Kawagoe City, Saitama Prefecture

Objective The Kawagoe City Public Health Center implemented a project to reduce salt intake through specific food service facility guidance in workplace cafeterias. Here, we report the study results.Methods The target worksite was company A, with approximately 270 employees, located in Kawagoe City, Saitama Prefecture. There were 214 participants (approximately 80%). The project was conducted from November 2019 to November 2021. The long-term goal was to decrease the number of hypertensive cases in the city. Project outcomes included decreased salt intake, urinary sodium/potassium ratio, and average blood pressure. The project aimed to improve the cafeteria menu, focusing on salt reduction by offering Smart Meals® and reducing the salt equivalents in all menus. The project output indicators included reduced amount of salt in cafeteria menu items, increased frequency of cafeteria use, increased positive evaluations of the cafeteria, and increased daily awareness of the need for salt reduction. Spot urine samples, blood pressure measurements, and self-administered questionnaire data were collected during annual physical examinations. The amount of salt in the cafeteria menu was evaluated by receiving monthly data from the food service company to which company A outsourced its cafeteria operations.Results The analysis included 102 individuals with complete data from to 2019-2021. Estimated salt intake (g/day) from spot urine decreased from 10.3±2.1 in 2019 to 9.8±2.4 in 2020 and 9.5±2.0 in 2021 (P=0.003). Systolic blood pressure (mmHg) decreased from 114.7±12.5 in 2019 to 111.7±12.1 in 2020 and 110.6±12.0 in 2021 (P=0.010). Compared to 2019, changes in dietary salt equivalents in cafeteria menus in 2020 and 2021decreased for set meals A and B, curries, and noodles (P<0.001).Conclusion We offered Smart Meals® and reduced salt equivalents in all workplace cafeteria menus. After 1-2 years, employees' salt intake and blood pressure levels were lower. These results provide implications for the implementation of food environment improvements in public health centers and other local government agencies to promote the Health Japan 21 (third term) strategy.

Slipping Through the Cracks: Clinicians' Perspectives on the Gaps in New York City's Public Mental Health System.

Most people who seek mental health treatment cannot access it. Certain groups (e.g., Medicaid enrollees and the uninsured) face particularly severe treatment access barriers along the care continuum. We interviewed 31 clinicians across two studies about their perspectives working in New York City's public mental health system. Because every clinician across both studies reported gaps in the system, we deployed an emergent, "serendipitous finding" approach and qualitatively analyzed the interviews together. Clinicians described three public mental health system gaps. First, many treatment-seekers must wait long periods of time to receive care and some never receive it at all. Second, patients with more serious challenges cannot access longer-term, higher-intensity, or specialized treatment. Third, some patients receiving high-intensity services may benefit from lower-intensity mental health support that is better integrated with medical and social service support. Coordinated and sustained financial investments at every step of the mental healthcare continuum are needed.

Knowledge and utilization of iodized salt among expectant mothers in Harar City's public health facilities: a multicenter study in Eastern Ethiopia.

Insufficient iodine intake during pregnancy can result in abortion, stillbirths, neonatal mortality, cretinism and permanent cognitive impairment. Even although iodized salt is widely accessible in Ethiopia, pregnant women still experience persistent problems related to iodine deficiency disorders. A facility-based cross-sectional study was conducted among randomly selected 573 pregnant women who were attending antenatal care services at public health facilities. Bivariate and multivariable logistic regression models were used, and independent predictors were determined based on adjusted ORs with 95% CIs and p<0.05. Knowledge and practice of pregnant women on iodized utilization were 35.6% (95% CI 31.8 to 39.6%) and 37.7% (95% CI 32.1 to 42.9%), respectively. Living in urban areas (adjusted OR [AOR]=1.976, 95% CI 1.136 to 3.435) and having a higher level of education (AOR=2.018, 95% CI 1.037 to 3.930) were associated with having adequate knowledge. Having a diploma or higher education (AOR=2.684, 95% CI 1.137 to 6.340) and adequate knowledge about iodized salt utilization (AOR=2.095, 95% CI 1.273 to 3.447) were significantly associated with good practice. The current study highlights the level of knowledge and practices of pregnant women on iodized salt. It emphasizes the necessity for targeted programs about the benefits of iodized salt and how to use it correctly, particularly for those with low literacy levels and those living in rural areas.

Research on smart city public health detection system and improvement technology based on intelligent multi-objective.

With the increase of urban population density, urban sanitation becomes more severe; urban sanitation has important influence on public health. Therefore, in order to realize the detection of public health in smart cities, the research will use cutting-edge scientific and technological methods to improve urban environmental health, so as to promote the realization of public health achievements. This study introduces public health detection and optimizationtechnologies for smart cities. Firstly, a data detection system for urban public health environment was established using sensors and intelligent multi-objective technology to evaluate the water quality, air quality, and noise level of the city. Then, an intelligent garbage management system based on Tensor-flow was constructed to achieve efficient garbage collection and treatment. Finally, an intelligent traffic management system was developed to monitor and regulate urban traffic flow. The results of the simulation experiment demonstrated that the life data detection system was operationally stable, with a high success rate of 98%. Furthermore, its accuracy in detecting residents' living environment data was above 95%, the maximum relative error was only 0.0465, making it a reliable and efficient tool. The waste recycling system achieved a minimum accuracy of 83.6%, the highest accuracy rate was 95.3%, making it capable of sorting and recycling urban waste effectively. Additionally, the smart traffic management system led to a 20% reduction in traffic congestion rates, 20 tonnes less tailpipe emissions and an improvement in public health and well-being. In summary, the plan proposed in this study aims to create a more comfortable, safe, and healthy urban public health environment, while providing theoretical support for environmental health management in smart cities.

Impact of Air Quality Index of Pune City: A Review

This work aims to perform a comprehensive analysis of earlier studies on Pune City's Air Quality Index (AQI). The main objectives are to define and analyze the current state of knowledge on Pune's air quality, point out significant study gaps, and provide details regarding upcoming studies and policies. According to the literature review, the quality of air in Pune City is declining due to its growing population. The primary air adulterants responsible for high AQI readings are particulate matter (‘PM-10 and PM-2.5’), nitrogen dioxide (‘NO2’), sulfur dioxide (‘SO2’), carbon monoxide (‘CO’), and ozone (‘O3’). Research reveals that industrialization, urbanization, and auto emigration all have an impact on air quality. Meteorological and seasonal conditions greatly impact the AQI readings in Pune. Research is necessary to determine the long-term health impacts of increased AQI levels, with more attention to sensitive groups like children, the elderly, and those with pre-existing medical issues. Furthermore, studies examining the efficacy of present regulatory measures and putting forth creative ways to improve air quality are essential. Pune City's air quality situation is thoroughly described in this literature review, which adds to the body of knowledge already in existence. A comprehensive approach and multidisciplinary cooperation are needed to tackle the intricate problems related to air quality in metropolitan settings such as Pune, as the synthesis of existing information makes clear. In the end, this assessment seeks to encourage additional investigation and action to lessen the negative impacts of air pollution on Pune City's environment and general public health.

Expanding Outcomes in Cancer Screening Safety Net Programs: Promoting Sustainability and Policy Reform.

Community-engaged patient navigation safety net programs are established as an evidence-based approach to address cancer prevention and early detection efforts, but barriers to expand and sustain such programs persist. In addition, few studies describe how these programs impact buy-in among communities and policy change within health care systems and government. We describe how we used the Capacity for Sustainability Framework to guide efforts for program sustainability and community, institutional, and policy level change in a breast cancer screening and patient navigation safety net program. The nine domains of the Capacity for Sustainability Framework were used to develop program logic models, to inform program implementation and quality improvement agendas, and to guide multi-level partner and stakeholder engagement, outreach, and dissemination of outcomes. The program is currently in its seventh year and continues to be annually funded by a city public health department. In 2021, additional 5-year renewable funding from a state public health department was secured. In addition, institutional program support was expanded for patients diagnosed with breast cancer. Program leaders worked with policymakers to draft legislation to support training certification and third-payor reimbursement for patient navigators and community health workers. The program is well-known and trusted among community members, community-based organizations, and providers. Community, organizational, and policy-level outcomes demonstrate that community-engaged patient navigation safety net programs can influence more than individual and interpersonal outcomes and can be sustained over time.

This article investigates the multifaceted challenges resulting from concentrated and unidirectional migration to Bishkek, the capital of the Kyrgyz Republic. The study addresses the urgent need to rectify disparities in internal migration patterns and housing opportunities within Bishkek. By analyzing the intricate relationship between housing dynamics and migration inflows, the research underscores the critical importance of these dynamics for effective urban planning. A novel approach is proposed, advocating for the creation of a Bishkek agglomeration model aimed at fostering more balanced urban development and creating an accessible environment for public health. The primary objective of this study is to elucidate the correlation between the construction of new housing infrastructure and the overall state of housing deprivation across the country. The findings provide valuable insights and recommendations for administrative bodies responsible for managing migration and housing policies aimed at creating a healthy living environment.

Targeted Infection Control Practices in Japanese Hospitals for Multidrug-Resistant Organisms: Guidance From the Public Health Center.

Introduction The study conducted by the Kawaguchi City Public Health Center (PHC) in 2023 on hospital infection control (IC) programs revealed that hospitals can improve their IC programs if the PHC provides training sessions (TSs) that have numerical effects. In this study, we expected that we could help hospitals develop their IC practices by providing targeted guidance. This study aimed to clarify targeted guidance on IC practices and TS programs to develop hospitals'hospitals' IC programs on multidrug-resistant organisms (MDROs) by examining hospitals'hospitals' IC programs in reference to the study conducted in 2023 and other case reports. Methods In June 2022, the Kawaguchi City PHC conducted TSs for 19 hospitals and eight affiliated (AFs) clinics with beds, providing guidelines and practices on infection control (IC) for MDROs. After the TSs, we sent a questionnaire to these hospitals and affiliated clinics. The questionnaire inquired about current and planned IC policies, hand hygiene compliance programs (HHCPs), the usefulness of the TSs conducted by the PHC, and IC programs that the facilities intended to implement or develop in the future. This study examined the relationship between the perceived usefulness of the information provided and the IC programs planned for development, referencing a study conducted in 2023 and other case reports. Results Seventeen hospitals and six AFs with beds responded to the survey, yielding an 85.2% response rate. IC policies for methicillin-resistant Staphylococcus aureus (MRSA) were prepared by 21 hospitals (91.3%), whereas only five hospitals (21.7%) had prepared IC policies for carbapenem-resistant Enterobacteriaceae. Regarding HHCPs, an increase in the availability of alcohol-based hand sanitizer was identified by 17 hospitals (73.9%), while 13 hospitals (56.5%) reported using posters or symbols, 12 hospitals (52.2%) reported using TS and hand sanitizers, and nine hospitals (39.1%) assessed HH compliance and provided feedback. Furthermore, nine hospitals (39.1%) identified HHCPs and Environmental Cleaning (EC) for carbapenemase-producing Enterobacteriaceae (CPE) as useful information. There was a statistically significant association between TSs on HHCPs and the development of new HHCPs (p = 0.027). Additionally, information on EC for CPE was significantly associated with the development of staff cohorting strategies (p = 0.007). However, TS programs were not significantly connected to EC, nor were TSs to be developed. Conclusion The PHC should advise hospitals to assess if their HHCPs effectively contribute to improving HH compliance. It is essential for the PHC to furnish hospitals with resources and information that aid in the development of EC training. Additionally, the PHC should support the creation of specific and effective TS programs focused on EC or TS development. Conducting surveys to identify barriers to implementing staff cohorting strategies is also recommended. We propose that TS programs should include quantifiable data on HHCPs and EC, such as.

Public Health Centers' Training Session Programs to Develop Programs on Infection Control Practices for Multidrug-Resistant Organisms in Hospitals in Kawaguchi City, Japan.

Introduction The Kawaguchi City Public Health Center (PHC) conducted training sessions focusing on infection control practices on multidrug-resistant organisms (MDROs) for 19 hospitals and eight affiliated clinics (AFs) with beds in June 2022. Issues with infection control programs were identified via a survey implemented following the training sessions. These included providing feedback on infection control policies for MDROs, hand hygiene compliance programs (HHCPs), environmental cleaning (EC), and training sessions programs that hospitals or AFs with beds (hospitals) intended to implement in the future or develop (to be developed). We planned to examine whether the PHC training sessions programs have an effect on the development of hospital infection control programs designed to address these issues. The purpose of this study is to clarify the training session program provided by the Kawaguchi City PHC, which was effective in developing hospital infection control programs based on the results of the survey conducted after the training session. Methods In June 2023, a second training session that offered information on infection control practices was completed for 30 hospitals. This was followed by sending a questionnaire. We examined infection control programs to be developed and analyzed associations with the first learned information by training session (the first learned information). Results Twenty-four hospitals responded to the survey with a response rate of 80.0%. Half the respondents (12, 50.0%) had prepared for the infection control policy on carbapenem-resistant Enterobacteriaceae (CRE), 11 hospitals (45.8%) had provided feedback on HHC, and four (16.7%) planned to conduct feedback on HHC. HHCPs were planned to be developed by 19 hospitals (79.2%), EC by five hospitals (20.8%), training sessionby 12 hospitals (50.0%), and screening of MDROs upon hospital admission (AS) by nine hospitals (37.5%). The first learned information, "the prevention of healthcare-associated infections and cost savings by implementing cleaning bundles (the effects of cleaning bundles)," was identified by 10 hospitals (41.7%), and "specific programs on providing feedback effective for developing hand hygienecompliance (specific feedback)" was learned by eight hospitals (33.3%). The first learned information regarding specific feedback was significantly associated with HHCPs to be developed (p = 0.044). The first learned information on the effects of cleaning bundles was significantly associated with HHCPs and HHC feedback to be developed (p = 0.023, 0.034). The training sessionprograms were not significantly connected to EC, training session, or AS to be developed. Conclusions Infection control programs to be developed were linked to the provision of information on numerical effects by implementing specific feedback and cleaning bundles. We suggest that the PHC should develop infection control programs for the hospitals and provide training sessions, including numerical effects.

The application has received positives feedbacks from Prolanis participants, Although some participants have complainedabout limited access to smartphones and the need for assistance for elderly participants.

The state of COVID-19 vaccine confidence and need in Black individuals in Canada: Understanding the role of sociodemographic factors, health literacy, conspiracy theories, traumatic stressors and racial discrimination

BackgroundBlack communities in Canada have been among the most affected by the COVID-19 pandemic, in terms of number of infections and deaths. They are also among those most hesitant about vaccination against COVID-19. However, while a few studies have documented the factors associated with COVID-19 vaccine hesitancy, those related to vaccine confidence remain unknown. To respond to this gap, this study aims to investigate factors associated to vaccine confidence in Black individuals in Canada. MethodsA total of 2002 participants (1034 women) aged 14 to 89 years old (Mean age = 29.34, SD = 10.13) completed questionnaires assessing sociodemographic information, COVID-19 vaccine confidence and need, health literacy, conspiracy beliefs, major racial discrimination, and traumatic stressors related to COVID-19. ResultsResults showed an average score of COVID-19 vaccine confidence and need of 33.27 (SD = 7.24), with no significant difference between men (33.48; SD = 7.24) and women (33.08; SD = 7.91), t (1999) = 1.19, p = 0.234. However, there were significant differences according to employment status, migration status, age, inhabited province, spoken language, education, marital status, religion, and income. The linear regression model explained 25.8 % of the variance and showed that health literacy (B = 0.12, p < 0.001) and traumatic stressors related to COVID-19 (B = 0.21, p < .001) predicted COVID-19 vaccine confidence and need positively, while conspiracy beliefs (B = −1.14, p < 0.001) and major racial discrimination (B = −0.20, p = 0.044) predicted it negatively. ConclusionsThis study showed that building the confidence of Black communities in vaccines requires health education, elimination of racial discrimination in the Canadian society and a focus on certain groups (e.g., young people, those living in Quebec and Ontario). The results also argue in favor of involving community leaders and organizations in the development and implementation of vaccination-related tools, strategies and programs by city, provincial and federal public health agencies.
