Distribution of nursing workforce in the world using Gini coefficient.

INTRODUCTION: Unequal Access to human resources for health, reduces access to healthcare services, worsens the quality of services and reduces health outcomes. This study aims to investigate the distribution of the nursing workforce around the world. METHODS: This is a descriptive-analytical study, which was conducted in 2021. The number of nurses and world populations was gathered from World Health Organization (WHO) and The United Nations (UN) databases. The UN has divided world countries based on the Human Development Index (HDI) into four categories of very high, high, medium and low HDI. To investigate the distribution of the nurses around the world, we used the nurse population ratio (per 10,000 population), Gini coefficient, Lorenz curve and Pareto curve. FINDINGS: On average, there were 38.6 nurses for every 10,000 people in the world. Nations with the very high HDI, had the highest nurse/population ratio (95/10,000), while the low HDI nations had the lowest nurse/population ratio (7/10,000). Most nurses around the world were females (76.91%) who were in the age group of 35-44 (29.1%). The Gini coefficient of nations in the each four HDI categories varied from 0.217 to 0.283. The Gini coefficient of the nations between the four HDI categories was 0.467, and the Gini coefficient of the whole world was 0.667. CONCLUSION: There were inequalities between countries all over the world. Policymakers should focus on the equitable distribution of the nursing workforce across all local, national and regional levels.

Incidence and pattern of traumatic spine injury in a single level I trauma center of southern Iran.

PURPOSE: Spine injury is one of the leading causes of death and mortality worldwide. The objective of this study was to determine the incidence, pattern and outcome of trauma patients with spine injury referred to the largest trauma center in southern Iran during the last 3 years. METHODS: This is a cross-sectional study conducted between March 2018 and June 2021 in the largest trauma center in the southern Iran. The data collection form included the age, sex, injury location (cervical, thoracic, and lumbar), cause of injury (traffic accidents, falls, and assaults), length of hospital stay, injured segment of spine injury, severity of injury, and outcome. Statistical analyzes were performed using SPSS software version 24. RESULTS: Totally 776 cases of spine injury were identified. The spine injury rate was 17.0%, and the mortality rate was 15.5%. Cervical spine injury (20.4%) more often occulted in motorcycle accident, and thoracic spine injury (20.1%) occulted in falls. The highest and lowest rates of spine injurys were related to lumbar spine injury (30.2%) and cervical spine injury (21.5%), respectively. There was a statistically significant relationship between the mechanism of injury and the location of spine injury (p < 0.001). And patients with lumbar spine injury had the highest mortality rate (16.7%). Injury severity score (OR= 1.041, p < 0.001) and length of stay (OR = 1.018, p < 0.001) were strong predictors of mortality in trauma patients with spine injury. CONCLUSION: The results of the study showed that the incidence of traumatic spine injury rate was approximately 17.0% in southern of Iran. Road traffic injury and falls are the common mechanism of injury to spine. It is important to improve the safety of roads, and passengers, as well as work environment, and improve the quality of cars. Also, paying attention to the pattern of spine injury may assist to prevent the missing diagnosis of spine injury in multiple trauma patients.

Comparison of Health Status Indicators in Iran with the Eastern Mediterranean Countries Using Multiple Attribute Decision-Making Methods.

Background: Improving public health is the main goal of healthcare systems across the world. Healthcare policymakers often use comparisons between different healthcare systems to better position their country and use the outcome to develop novel strategies to improve their own public health. The present study aimed to compare the health status indicators in Iran with those of the Eastern Mediterranean (EM) countries using the multiple attribute decision-making (MADM) methods. Methods: A descriptive-analytical study was conducted in 2021 at Shiraz University of Medical Sciences, Shiraz, Iran. Data on the ranking of health status indicators in EM countries were obtained from the annual publications of the World Health Organization, World Health Statistics (2016-2020). As part of the MADM mathematical models, the "criteria importance through intercriteria correlation" (CRITIC) model was used to assign weights to health status indicators. In addition, the "multi-criteria optimization and compromise solution" (VIKOR) model was used to rank the EM countries. Results: The results showed that Bahrain and Somalia ranked first and last on health status indicators, respectively. Iran was ranked fifth among the EM countries. However, while Iran has a better status on all indicators than the mean value of all EM countries, there is a significant gap between the health status in Iran compared to the top-ranked countries. Conclusion: Health care strategies adopted by top-ranked countries, such as Bahrain and Qatar, can be used by Iran and other EM countries as a model to improve their healthcare system.

Effect of COVID-19 Pandemic on Incidence and Mortality Rate Due to Road Traffic Injury in Shiraz.

Objective: To evaluate the effect of COVID-19 pandemic on the incidence and mortality rate of road traffic injuries in Shiraz, Iran. Methods: This cross-sectional study was performed on the data of patients who admitted by road traffic accidents 18 months before the outbreak of COVID-19 and 18 months after COVID-19 in the largest provider of trauma level 1 care services in southern Iran. SPSS 19 software was used to analyze the data. Results: A significant decrease of 12.8% was observed in the number of patients admitted by road traffic accidents during the COVID-19 pandemic period compared to the same period before the pandemic (p<0.0001). But the death toll from road traffic accidents has increased significantly during the COVID-19 pandemic period compared to the same period before the pandemic (p=0.01). Conclusion: Due to the COVID-19 restrictions, it seems that factors such as restrictions on suburban travel, closure of public and recreational spaces, reduction of intra-city traffic, people staying at home and a significant reduction in injuries caused by traffic accidents, is reasonable. On the other hand, these restrictions, quarantines, and COVID disease itself can lead to confusion, anxiety, fear of infection, and thus avoid or delay the search for health care and increase mortality. Therefore, planning and policy-making is essential in order to prepare the correct guidance for seeking treatment.

Evaluation of the World Countries Health Referral System Performance Based on World Health Organization Indicators Using Hybrid Multi-Criteria Decision-Making Model.

OBJECTIVES: Primary healthcare will not be effective unless there is a proper referral system. In contrast, comparing the performance of healthcare systems provides an opportunity for policy makers to determine the status of the country's healthcare system compared with their international counterparts. Therefore, we ranked the countries in terms of indicators affected by the referral system. METHODS: This study was conducted in 2020. In the first phase, which was to determine the indicators affected by a country's referral system, data were collected by the Delphi method, and therefore, 13 indicators with a content validity ratio equal to or greater than 0.42 were selected. In the second phase, the data of 13 indicators selected in the first phase were extracted from the 2018 and 2019 World Health Organization reports. The weight of the indicators was calculated based on the Decision-Making Trial and Evaluation Laboratory method-based Analytic Network Process (DANP) and Shannon's entropy, and the VIekriterijumsko KOmpromisno Rangiranje (VIKOR) method was used to rank the countries. SPSS 24 and Excel 2013 software were used for data analysis. RESULTS: Switzerland, Germany, and Sweden ranked first, second, and third, respectively. In all the 3 countries, there are no mandatory gatekeeping systems. Physicians, especially general practitioners, are the core of primary healthcare, and in all the 3 countries, there is a uniform and coherent health financing system that is either based on mandatory health insurance (Switzerland and Germany) or taxes (Sweden). India had the lowest ranking. CONCLUSIONS: It seems that the study of the health system of the countries that have obtained higher rankings can indicate their efforts in establishing a gatekeeping system, family physician program, and appropriate financing system. Therefore, other countries can study successful countries and copy them as a model to improve their health system.

Inappropriate hospital stays and association with lack of homecare services.

BACKGROUND: Efforts to reduce inappropriate hospital stay, including alternatives such as homecare, are important to improve patient care and reduce health care costs. AIMS: This study evaluated inappropriate hospital stay in Shiraz, Islamic Republic of Iran and the extent to which these stays were due to lack of homecare services and others factors needed for homecare. METHODS: This cross-sectional study was conducted between January 2018 and September 2019 at two public hospitals in Shiraz. All adult patients hospitalized in these two hospitals in the study period were included, except patients in mental care wards. Appropriateness of patients' hospital stay was assessed on a daily basis using the Iranian version of the Appropriateness Evaluation Protocol. The chi-squared test was used to assess association between need for homecare and patient characteristics. RESULTS: Of 6458 hospitalization days assessed (for 1954 patients), 710 (11.0%) days were inappropriate. The greatest proportion of causes of inappropriate stay were physician-related (32.9%). Of the 710 inappropriate hospitalization days, 231 were due to lack of homecare services. Most patients who were inappropriately hospitalized because of lack of homecare services were insured through Salamat insurance (64.0%). A statistically significant relationship was found between the need for homecare services and the type of health insurance (P = 0.01). Of the patients admitted to hospital because of lack of homecare services, 36.8% had endocrine diseases, especially diabetes, and 21.8% needed oxygen services. CONCLUSION: Institutionalizing home health care in the Iranian health system could encourage more home health care referral and reduce inappropriate hospitalization, especially for diabetes.

All-digital Stokes polarimetry with a digital micromirror device.

Stokes polarimetry is widely used to extract the polarization structure of optical fields, typically from six measurements, although it can be extracted from only four. To measure the required intensities, most approaches are based on optical polarization components. In this work, we present an all-digital approach that enables a rapid measure of all four intensities without any moving components. Our method employs a polarization grating (PG) to simultaneously project the incoming mode into left- and right-circular polarized states, followed by a polarization-insensitive digital micromirror device (DMD), which digitally introduces a phase retardance for the acquisition of the remaining two polarization states. We demonstrate how this technique can be applied to measuring the SoP, vectorness, and intramodal phase of optical fields, without any moving components, and shows excellent agreement with theory, illustrating fast, real-time polarimetry.

Ranking of Iranian provinces based on healthcare infrastructures: before and after implementation of Health Transformation Plan.

BACKGROUND: Health Transformation Plan (HTP) was occurred in 2014 to improve access and equity and reduce out of pocket payments in Iranian Health Care System. In this regard the aim of this study is evaluating and ranking the service provider's infrastructures among the country provinces as an indicator of equity before and after implementation of the HTP. METHODS: This cross sectional study is conducted in 2017. The study population included 31 provinces of the country. Data related to 4 years from 2012 to 2016 were included from the data bases of Ministry of Health and Medical Education as well as the statistics yearbook of the country. The obtained results of multi-criteria decision-making methods were analyzed as well. SPSS18 and Excel2013 software were used for data analysis. RESULTS: Based on the VIKOR method, in 2012, Mazandaran, Tehran and Fars provinces and in 2013, the provinces of Tehran, Fars and Isfahan ranked from first to third respectively. Similarly after HTP, in 2015, the provinces of Tehran, Khorasan Razavi and Fars and in 2016 the provinces of Tehran, Fars and Khorasan Razavi have ranked from first to third respectively. Paramedic, dentist, pharmacist, medical institutions and hospital bed had a significant difference before and after the implementation of Health Transformation Plan, so that the number of these indicators increased after implementation of the HTP (P value < 0.05). CONCLUSIONS: According to the results, there are many differences between the provinces and these disparities have not decreased significantly after HTP. Consequently, it is suggested to the health sector policy makers to make regional plans and allocate the budget of HTP, based on the status of the provinces. In addition, responding to these inequalities requires a transparent and systematic approach to provide the budget for allocating to the population, health needs, and the lack of development and geographical isolation of regions.

Economic Burden of Gastric Cancer: A Case of Iran.

PURPOSE: Today, cancers have become a major cause of mortality in developed and developing countries. Among various cancers, gastric cancer imposes a huge economic burden on patients, their families, and on the health-care system. This study aimed to determine the economic burden of gastric cancer in Kohgiluyeh and Boyer Ahmad province of Iran in 2016. METHODS: This was a cross-sectional cost of illness study conducted in Kohgiluyeh and Boyer Ahmad province of Iran in 2016, using a prevalence-based approach. All patients were studied using the census method (N = 110). The required data on direct medical, direct nonmedical, and indirect costs were collected using a data collection form from the patients' medical records, tariffs of diagnostic, and therapeutic services approved by the Ministry of Health and Medical Education in 2016. RESULTS: The total cost and burden of gastric cancer in Kohgiluyeh and Boyer Ahmad province of Iran in 2016 were $US436 237, among which the majority were direct medical costs (59%). The highest costs among direct medical costs, direct nonmedical costs, and indirect costs were, respectively, related to the costs of medications used by the patients (35%), transportation (31%), and absence of patients' families from work and daily activities caused by patient care (56%). CONCLUSION: Our study has revealed for the first time high costs of gastric cancer in Iran. To decrease the total costs and burden, the following suggestions can be made: increasing insurance coverage and government subsidies for purchasing necessary medications, providing the required specialized care and services related to cancer diseases such as gastric cancer in other provincial cities rather than just in capital cities, and so on.
