    Abstract The global health security (GHS) Index assesses countries' level of preparedness to health risks. However, there is no evidence on how and whether the effects of health systems building blocks and socioeconomic indicators on the level of preparedness differ for low and high prepared countries. The aim of this study was to examine the contributions of health systems building blocks and socioeconomic indicators to show differences in the level of preparedness to health risks. The study also aimed to examine trends in the level of preparedness and the World Health Organization (WHO) regional differences before and during the Covid-19 pandemic. We used the 2021 GHS index report data and employed quantile regression, log-linear, double-logarithmic, and time-fixed effects models. As robustness checks, these functional form specifications corroborated with one another, and interval validity tests confirmed. The results show that increases in effective governance, supply chain capacity in terms of medicines and technologies, and health financing had positive effects on countries' level of preparedness to health risks. These effects were considerably larger for countries with higher levels of preparedness to health risks. The positive gradient trends signaled a sense of capacity on the part of countries with higher global health security. However, the health workforce including doctors, and health services including hospital beds, were not statistically significant in explaining variations in countries' level of preparedness. While economic factors had positive effects on the level of preparedness to health risks, their impacts across the distribution of countries' level of preparedness to health risks were mixed. The effects of Social Development Goals (SDGs) were greater for countries with higher levels of preparedness to health risks. The effect of the Human Development Index (HDI) was greatest for countries whose overall GHS index lies at the midpoint of the distribution of countries' level of preparedness. High-income levels were associated with a negative effect on the level of preparedness, especially if countries were in the lower quantiles across the distributions of preparedness. Relative to poor countries, middle- and high-income groups had lower levels of preparedness to health risks, an indication of a sense of complacency. We find the pandemic period (year 2021) was associated with a decrease in the level of preparedness to health risks in comparison to the pre-pandemic period. There were significant WHO regional differences. Apart from the Eastern Mediterranean, the rest of the regions were more prepared to health risks compared to Africa. There was a negative trend in the level of preparedness to health risks from 2019 to 2021 although regional differences in changes over time were not statistically significant. In conclusion, attempts to strengthen countries' level of preparedness to health shocks should be more focused on enhancing essentials such as supply chain capacity in terms of medicines and technologies; health financing, and communication infrastructure. Countries should also strengthen their already existing health workforce and health services. Together, strengthening these health systems essentials will be beneficial to less prepared countries where their impact we find to be weaker. Similarly, boosting SDGs, particularly health-related sub-scales, will be helpful to less prepared countries. Moreover, there is a need to curb complacency in preparedness to health risks during pandemics by high-income countries. The negative trend in the level of preparedness to health risks would suggest that there is a need for better preparedness during pandemics by conflating national health with global health risks. This will ensure the imperative of having a synergistic response to global health risks, which is understood by and communicated to all countries and regions.

    Abstract This study recognises periodic outbreaks of measles continue to affect conflict and fragile zones in the least developed countries. This study set out to provide evidence for the indirect costs or economic loss associated with measles-related deaths among children aged 0-14 years in Somalia. Using epidemiologic and economic data, the indirect cost was calculated based on the framework of the World Health Organisation guide of identifying the economic consequences of disease and injury. The baseline indirect cost was computed as the product of discounted future productive years of life lost (PYLL), non-health gross domestic product per capita (NHGDPPC) and the estimated total measles deaths (ETMD). The model was adjusted for conflict and fragility conditions and further extension considered a finite and stable upper limit growth of the instability-adjusted NHGDPPC. To discount future costs, a rate of 3% was applied. Using a ±20% variability assumption of the epidemiologic and economic factor inputs, a sensitivity analysis was conducted to account for uncertainty. In 2015 values, the ETMD of 3723 measles deaths of children aged 0-14 years could decrease non-health GDP of the country by $23.46 million, a potential loss of $6303 per death over the discounted PYLL. The loss would increase by 5.3% when adjusted for conflict and fragility conditions. Assuming growth, the future adjusted loss is expected to be $35.91 million in 2015 values. Girl-child deaths accounted for 51.2% of the burden. Results are robust to the variations in the model inputs, although sensitivity analyses suggest the proportion of total measles deaths and the discount rate accounted for greater uncertainty of the loss than do the proportion of growth and instability assumption. Conflict and fragility accounted for the least uncertainty, perhaps confirming their relative perpetuity in Somalia. Results show significant indirect cost related to measles deaths of children, exacerbated by conflict and fragility. This is an economic burden, but one which the health system, policy-makers, government and other stakeholders should be prepared to colossally discount by collectively taking measles surveillance and security measures now to reduce further deaths in the future.

    Abstract Background: Low tuberculosis (TB) detection and conflict and fragility have overburdened Somalia. This study estimated economic loss associated with TB deaths among persons aged >14 years.
    Method: Using epidemiologic and economic data, we calculated the cost based on the framework of the World Health Organization guide of identifying the economic consequences of disease and injury. Baseline loss is the product of years of life lost, non-health expenditure, and number of deaths. Adjusting for conflict and fragility conditions and growth of non-health expenditure, we discounted the loss at 3% rate. We conducted a sensitivity analysis of epidemiologic and economic factors.
    Results: In 2017 values, the 9180 reported deaths result in a loss of US$ 44.77 million, a US$ 4877 per death over the discounted years. Conflict conditions would increase the loss by 5.3%, while simultaneous adjustment for conflict and attunement to growth of non-health expenditure would increase the burden by 54% to US$ 67.28 million. Male fatalities account for 59% of the burden. The baseline result is robust to input variations, although sensitivity analysis suggests conflict and fragility conditions account for greater uncertainty of the loss.
    Conclusion: Stakeholders in the healthcare system should minimise the sizeable economic loss by taking measures to enhance surveillance of TB and security.

    Abstract Background: Disposition decision-making in the emergency department (ED) is crucial to patient safety and quality of care. It can inform better care, lower chance of infections, appropriate follow-up care, and reduced healthcare costs. The aim of this study was to examine correlates of ED disposition among adult patients at a teaching and referral hospital based on patients' demographic, socioeconomic, and clinical characteristics.
    Method: A cross-sectional study conducted at the ED of the King Abdulaziz Medical City hospital in Riyadh. A two-level validated questionnaire was used-a patient questionnaire and healthcare staff/facility survey. The survey employed a systematic random sampling technique to recruit subjects at a pre-specified interval as patients arrived at the registration desk. We analyzed 303 adult patients visiting the ED, who were triaged, consented to participate in the study, completed the survey, and admitted to a hospital bed or discharged home. We used descriptive and inferential statistics to summarize and determine the interdependence and relationships of variables. We used logistic multivariate regression analysis to establish relationships and the odds of admission to a hospital bed.
    Results: The mean age of the patients was 50.9 (SD = 21.4, Range 18 to 101). A total of 201 (66%) were discharged home while the rest were admitted to a hospital bed. Results of the unadjusted analysis suggest that older patients, males, patients with low level of education, and those with comorbidities and middle-income were more likely to be admitted to the hospital. The results of the multivariate analysis suggest that patients with comorbidities, urgent conditions, prior history of hospitalization, and higher triage levels were more likely to be admitted to a hospital bed.
    Conclusions: Having proper triage and timely stopgap review measures in the admission process can help new patients to locations that best support their needs and improve the quality and efficiency of the facility. The findings may be a sentinel indicator that informs overuse or inappropriate use of EDs for non-emergency care, which is a concern in the Saudi Arabian publicly funded health system.

    Abstract Introduction : We investigated the association between social distress or toxicity and patients’ clinical conditions, demographic characteristics, and social support and networks, and whether this association differs along the distribution of patients’ distress levels. This study included 156 patients treated at King Abdulaziz Medical City, Riyadh, Saudi Arabia. Methods : We used the previously validated Social Toxicity Assessment Tool in Cancer (STAT-C) to assess cancer patients’ distress. We analyzed distress level, the outcome variable of interest, and covariates to show distribution and identify associations. We then used logistic quantile regression for bounded outcomes to assess the association between social distress or toxicity and patients’ clinical conditions, demographic characteristics, and social support and network. As an extension, we examined the interaction between disease status and social support, focusing on the moderating role of social support in attenuating the impact of disease status on social distress. Results : The median age of the patients was 51.2 (SD = 21.4, range 22 to 89), with 48.1% being older than 50 years. Of the 156 cancer patients analyzed, 82 (52.6%) were classified as burdened, and 50% of those with uncontrolled disease status were socially distressed. However, there were more socially distressed patients diagnosed within a year and patients undergoing treatment. There was a greater number of patients who shared their diagnosis with family, colleagues, and neighbors with social distress. The odds of suffering from social distress were higher in younger patients (50 years or younger) than in older patients. Social distress was lower in patients who underwent combined chemotherapy, surgery, and radiation compared with patients who received a single treatment regimen (OR = 0.65, CI, −0.820 to −0.036, p = 0.033). The odds of social distress were 67% higher in patients diagnosed within one year than in patients diagnosed more than one year prior (OR = 1.664, CI, 0.100–0.918, p ...

    Abstract Background: As increasing the number of organ donations presents a global challenge, Saudi Arabia is no different. Intensivists can play a major role in maximizing the organ donation process and minimize the challenges. The purpose of this study was to investigate Saudi pediatric intensivists' comfort and importance levels of organ donation competencies.
    Methods: We conducted a cross-sectional survey whose sampling frame included 100 pediatric intensivists. The pediatrician intensivists were identified through an updated list provided by the Saudi Critical Care Society. We assessed 14 competencies categorized into four domains: the general donation, donation after brain death (DBD), neurological determination of death, and medicolegal, religious, and ethical domains. Then we investigated the association between these competencies and physicians' characteristics.
    Results: With a response rate of 76%, we found that 40-60% of the surveyed pediatric intensivists rated their comfort in 6 out of 14 competencies as high or very high. There was a statistically significant gap in the intensivists' rating of 10 competencies (i.e., high importance but low comfort levels). Ordinal regression showed that comfort levels with the general donation, neurological determination of death, and medicolegal, religious, and ethical domains were higher in intensivists who were frequently involved with DBD than those who had never been exposed.
    Conclusions: Pediatric intensivists expressed low comfort levels to organ donation competencies that are essential for maximizing donation rates. Adapting mandatory comprehensive donation education programs and dedicated physician specialists may be beneficial in critical care units aiming to increase donation rates.

    Abstract This short communication recognizes the underbelly of weak and conflict-prone health systems in the Middle East and North Africa region in the wake of COVID-19 pandemic. The communication highlights how the lack of basic resources, absence of a well-functioning health system and the dearth of well-coordinated communication channels, can bode ill for the successful fight against COVID-19. The article elucidates COVID-19 potential health, social, and economic implications for such countries. The communication cautions that if COVID-19 is left to incubate and makes a home in weak systems, it will have a much better chance of mutating and coming back to infect many people globally. The communication calls on the international institutions in collaboration with developed nations to be prepared to probe up health systems in weak and conflict-prone health systems with much-needed resources in order to nip COVID-19 in the bud.
