A dynamic management model for sustainable drug supply chain in hospital pharmacies in Iran.

BACKGROUND: Sustainable supply chain management encompasses the strategic coordination and control of material, information, and financial flows, as well as the collaborative efforts among the entities engaged in the medicinal supply chain. This research proposes a dynamic and sustainable supply chain management model tailored explicitly for the inpatient pharmacies of Medical Centers and Hospitals affiliated with Iran University of Medical Sciences. METHODS: This is a quantitative study in terms of research objective and a qualitative study based on the stages in the conceptual development of the model. Therefore, the current study can be considered a mixed-methods approach. After identifying the key factors influencing the sustainability of the medicine supply chain, we conducted a dynamic analysis of the problem using system dynamics methodology. In order to simulate the system's behavior over 24 months, we utilized a combination of existing documentary information and expert opinions. The developed model was implemented using Vensim PLE software, allowing us to simulate and analyze the impact of various policies on the system. RESULTS: Medicine disposal exhibited an upward trend, particularly during the second 12-month period. Conversely, the trend of medicine expirations remained relatively stable in the initial months but showed an upward trajectory after that. The cost associated with disposed medicine experienced a consistent increase, with a higher rate observed during the second 12-month period. In contrast, sales of low-consumable medicine experienced a significant initial surge followed by a slower growth rate. Finally, the pharmacy's profit demonstrated an overall increasing trend, although the rate of increase was higher during the first 12 months. CONCLUSION: Among the various scenarios considered, namely "increasing the adequacy of human resources," "increasing the speed of response," and "utilizing pharmacists in the drug prescribing team," it was found that these interventions had a substantial effect on both enhancing the pharmacy's profit and reducing medication waste. Therefore, these scenarios were identified as having the most significant impact. The proposed model can serve as a valuable tool for forecasting and informing policy-making, providing insights into addressing the challenges associated with the sustainable drug supply chain in hospital pharmacies.

The effect of circadian on the productivity of nurses with the mediating role of quality of work life.

BACKGROUND: Circadian rhythms, as an integral part of daily life, govern the scheduling, management, and coordination of living organisms. Given the irregular nature of shift patterns in nurses' work schedules, investigating their implications is paramount to increasing Quality of Work Life (QWL) and productivity. The study aimed to investigate the impact of circadian rhythm on the efficiency of nurses working in hospitals in Qazvin, Iran, with QWL serving as a mediating variable. METHODS: This study employed a descriptive-analytical research design, utilizing cross-sectional data collected in 2022-2023 based on the implementation of Structural Equation Modeling (SEM). The number of participants was 378 nurses. The data were obtained by administering a questionnaire and various tools, organized into four sections: demographic information, the Circadian Questionnaire, the Quality of Work Life Questionnaire, and the Nurses' Efficiency Questionnaire. The collected data were subsequently analyzed using SEM techniques within the R software. RESULTS: The findings demonstrated statistically significant variations in mean scores about gender and efficiency (p = 0.008), marital status and efficiency (p = 0.000), and employment type and efficiency (p = 0.002) among the study participants. There was a significant association between shift patterns and QWL (p = 0.004). Expressly, the confirmed results indicated a direct impact of circadian on QWL (with a path coefficient of 0.013), as well as an indirect impact on efficiency mediated by the variable QWL (with a path coefficient of 0.037) (p < 0.05). CONCLUSION: Due to the critical role of nurses in the healthcare system, implementing strategies that promote their efficiency is paramount. Therefore, managers can create an environment that enhances nurses' productivity by improving methods that positively impact their QWL.

A framework for elderly participation in Primary Health Care in Tabriz Health complexes.

BACKGROUND: A framework for increasing elderly participation in Primary Health Care (PHC) is a vital issue considering the growing population. After examining the situation and elderly participation in the provision of PHC in the health complexes of Tabriz City, the present study presents the framework of elderly participation in PHC. METHODS: This is a mixed-method study. First, we reviewed the models of elderly participation in PHC worldwide using a comprehensive search of literature. Then, we extracted the service providers' and the elderly's views regarding the obstacles and solutions for the elderly participation in PHC in Iran using the interviews and focus group discussions (FGD). We conducted three FGDs (8-10 people) and seven individual interviews. Data were analyzed using the content analysis method. We developed the proposed framework for the participation of the elderly in PHC using a panel of experts and checked and confirmed the framework's validity using the Delphi technique with 11 experts from the content validity index and modified kappa coefficient. RESULTS: Based on the result of included studies in the systematic review, the characteristics of the participation models were classified into five areas: the characteristics of the service user, the main facilitator of the intervention, the type of ownership of the center, the subject and the method of participation. The solutions and obstacles, and problems presented by the service providers and users in different areas include 12 themes (elderly participation, home care, and self-care, respect for the elderly, cooperation of different organizations, service package for the elderly, referral system, planning for the elderly, considering insurance for the elderly, the role of informing the elderly, mental health of the elderly, physical space of centers and training of elderly caregivers) and 46 sub-themes. The final framework also includes five themes (approaches and strategies to attract participation, indicators, and consequences of participation of the elderly, implementation strategies of elderly care, implementation infrastructure and goals and areas of participation of the elderly) and sub-themes. CONCLUSION: The results of the study indicate that the final framework obtained should be used based on a systematic model for elderly participation in PHC and should be implemented and followed up based on local strategies and specific indicators, considering all capacities.

The relationship between succession and intellectual capital with entrepreneurship in hospitals.

BACKGROUND: The hospital environment is very dynamic and faces many internal and external changes. Healthcare knowledge and technology are developing at a swift pace. This study investigated the relationship between succession and intellectual capital with entrepreneurship at the Qazvin University of Medical Sciences hospital, Iran. METHODS: The number of employees working in six hospitals was 2256, and according to Morgan's table, the required number of samples was 331. We distributed three hundred sixty-five questionnaires considering 10% of sample loss. We used a multi-stage stratified sampling method. In the first stage, each hospital was considered a stratum. After that, occupational groups were considered the next stratum within each hospital, and based on the ratio, the required number of samples for each occupational group was randomly selected. We used the Sobel test to investigate the mediating role of intellectual capital and the structural equation model to fit the research model. RESULTS: Succession aspects, including culturalization, meritocracy, job promotion path, and the role of senior managers, have a positive and significant effect on intellectual capital. Succession is only effective on intellectual capital and does not affect the personnel's entrepreneurship directly or through intellectual capital. CONCLUSION: Conducting training classes and intervention programs and using localized succession models can create a suitable platform for increasing organizational creativity and entrepreneurship, motivating the hospitals' personnel, and increasing intellectual capital.

Healthcare workers exposure risk assessment in the context of the COVID-19: a survey among frontline workers in Qazvin, Iran.

BACKGROUND: Healthcare workers perform various clinical procedures for COVID-19 patients facing an elevated risk of exposure to SARS-COV-2.This study aimed to assess the healthcare workers' exposure to COVID-19 in Qazvin, Iran in 2020. METHODS: We conducted this descriptive-analytical study among all healthcare workers on the frontline of exposure to COVID-19 in Qazvin province. We entered the participants into the study using a multi-stage stratified random sampling method. We utilized a questionnaire, "Health workers exposure risk assessment and management in the context of COVID-19 disease", designed by the World Health Organization (WHO) to collect data. We analyzed data using descriptive and analytical methods with SPSS software version 24. RESULTS: The results showed that all participants in the study had occupational exposure to the COVID-19 virus. So of 243 healthcare workers, 186 (76.5%) were at low risk and 57 (23.5%) at high risk of COVID-19 virus infection. Also, from the six domains mentioned in the questionnaire, health workers exposure risk assessment and management in the context of COVID-19 disease, the mean score of the domain of the type of healthcare worker interaction with a confirmed COVID-19 patient, the domain of health worker activities performed on a confirmed COVID-19 patient, the domain of the adherence to infection prevention and control (IPC) during health care interactions, and the domain of the adherence to IPC when performing aerosol-generating procedures in the high-risk group were more than the low-risk group. CONCLUSION: Despite strict WHO guidelines, many healthcare workers are exposed at contracting COVID-19. Therefore, healthcare managers, planners, and policymakers can revise the policies, provide appropriate and timely personal protective equipment, and plan for ongoing training for staff on the principles of infection prevention and control.

Measuring inequality in the distribution of health human resources using the Hirschman-Herfindahl index: a case study of Qazvin Province.

BACKGROUND: Achieving equity in the distribution of health services is one major goal in the health system. This study aimed to determine equality in distributing health human resources (physicians) in the Qazvin University of Medical Sciences before and after the Health Transformation Plan (HTP) based on the Hirschman-Herfindahl index (HHI). METHODS: In this descriptive-analytical study, the statistical population was general practitioners (GPs), specialists and subspecialists in the Qazvin University of Medical Sciences from 2011-to 2017. We extracted demographic statistics of the cities from the Statistical Center of Iran. Physicians' statistics were obtained from the Curative Affairs Deputy at the Qazvin University of Medical Sciences. We assessed inequality using the HHI. RESULTS: The highest number of GPs was in 2014, and specialists and subspecialists were in 2017. The lowest number of GPs, specialists, and subspecialists were in 2016, 2011 and 2015. The HHI for GPs in 2011-2017 was between 4300 and 5200. The lowest concentration for specialists before the HTP plan was the cardiologist with 3300, and after the HTP, the internal specialist with 3900. Also, the numerical value of this index for all subspecialty physicians after the HTP was 10,000, the highest level of concentration. CONCLUSION: The values obtained from the HHI index indicate the high concentration and disproportionate and inequitable distribution of human resources in the health sector in this province. The number of specialists in some cities is still much less than acceptable, and some cities even have shortcomings in the critical specialists.

Nurses' perception of patient safety culture and its relationship with adverse events: a national questionnaire survey in Iran.

BACKGROUND: Patient safety culture is an important factor in determining hospitals' ability to address and reduce the occurrence of adverse events (AEs). However, few studies have reported on the impact of nurses' perceptions of patient safety culture on the occurrence of AEs. Our study aimed to assess the association between nurses' perception of patient safety culture and their perceived proportion of adverse events. METHODS: A cross-sectional survey was carried out among 2295 nurses employed in thirty-two teaching hospitals in Iran. Nurses completed the Persian version of the hospital survey of patients' safety culture between October 2018 and September 2019. RESULTS: Positive Response Rates of overall patient safety culture was 34.1% and dimensions of patient safety culture varied from 20.9 to 43.8%. Also, nurses estimated that the occurrence of six adverse events varied from 51.2-63.0% in the past year. The higher nurses' perceptions of "Staffing", "Hospital handoffs and transitions", "Frequency of event reporting", "Non-punitive response to error", "Supervisor expectation and actions promoting safety", "Communication openness", "Organizational learning continuous improvement", "Teamwork within units", and "Hospital management support patient safety" were significantly related to lower the perceived occurrence at least two out of six AEs (OR = 0.69 to 1.46). CONCLUSIONS: Our findings demonstrated that nurses' perception regarding patient safety culture was low and the perceived occurrence of adverse events was high. The research has also shown that the higher level of nurses' perception of patient safety culture was associated with lowered occurrence of AEs. Hence, managers could provide prerequisites to improve patient safety culture and reduce adverse events through different strategies, such as encouraging adverse events' reporting and holding training courses for nurses. However, further research is needed to assess how interventions addressing patient safety culture might reduce the occurrence of adverse events.

Global trends of hand and wrist trauma: a systematic analysis of fracture and digit amputation using the Global Burden of Disease 2017 Study.

BACKGROUND: As global rates of mortality decrease, rates of non-fatal injury have increased, particularly in low Socio-demographic Index (SDI) nations. We hypothesised this global pattern of non-fatal injury would be demonstrated in regard to bony hand and wrist trauma over the 27-year study period. METHODS: The Global Burden of Diseases, Injuries, and Risk Factors Study 2017 was used to estimate prevalence, age-standardised incidence and years lived with disability for hand trauma in 195 countries from 1990 to 2017. Individual injuries included hand and wrist fractures, thumb amputations and non-thumb digit amputations. RESULTS: The global incidence of hand trauma has only modestly decreased since 1990. In 2017, the age-standardised incidence of hand and wrist fractures was 179 per 100 000 (95% uncertainty interval (UI) 146 to 217), whereas the less common injuries of thumb and non-thumb digit amputation were 24 (95% UI 17 to 34) and 56 (95% UI 43 to 74) per 100 000, respectively. Rates of injury vary greatly by region, and improvements have not been equally distributed. The highest burden of hand trauma is currently reported in high SDI countries. However, low-middle and middle SDI countries have increasing rates of hand trauma by as much at 25%. CONCLUSIONS: Certain regions are noted to have high rates of hand trauma over the study period. Low-middle and middle SDI countries, however, have demonstrated increasing rates of fracture and amputation over the last 27 years. This trend is concerning as access to quality and subspecialised surgical hand care is often limiting in these resource-limited regions.

Nurses' perceptions of evidence-based practice: a quantitative study at a teaching hospital in Iran.

BACKGROUND: Evidence-based practice (EBP) provides nurses a method to use critically appraised and scientifically proven evidence for delivering quality health care and the best decision that leads to quality outcomes. The purpose of this study was to measure the practice, attitude and knowledge/skill of evidence-based practice of nurses in a teaching hospital in Iran. METHODS: This cross-sectional study was conducted in 2011.The study sample was composed of 195 nurses who were working at the Fatemeh Zahra Hospital affiliated to Bushehr University of Medical Sciences (BPUMS). The survey instrument was a questionnaire based on Upton and Upton study. This tool measures Nurses' perceptions in the three sub-scales of practice, attitude and knowledge/skill of evidence-based practice. Descriptive statistical analysis was used to analyze the data. Pearson correlation coefficients were used to examine the relationship between subscales. RESULTS: The overall mean score of the evidence-based practice in this study was 4.48±1.26 from 7, and the three subscales of practice, attitude and knowledge/skill in evidence-based practice were, 4.58±1.24, 4.57±1.35 and 4.39±1.20, respectively. There was a strong relationship between knowledge and performance subscale (r=0.73,p<0.01). CONCLUSION: Findings of the study indicate that more training and education are required for evidence-based nursing. Successful implementation of evidence-based nursing depends on organizational plans and empowerment programs in hospitals. Hence, hospital managers should formulate a comprehensive strategy for improving EBP.

Inequality in the distribution of resources in the health sector before and after the Health Transformation Plan in Qazvin, Iran.

BACKGROUND: The equitable distribution of healthcare resources represents a paramount objective in the realm of global health systems. Thus, the present study sought to assess the fairness in the allocation of health resources at Qazvin University of Medical Sciences (QUMS), both prior to and subsequent to the implementation of the Health Transformation Plan (HTP) using the Gini coefficient and the Hirschman-Herfindahl index (HHI). METHODS: This descriptive-analytical study aimed to investigate the distribution of healthcare resources among general practitioners (GPs), specialists, and subspecialists employed at QUMS between 2011 and 2017. Demographic data pertaining to the cities were obtained from the statistical yearbooks of the Statistical Center of Iran, while information regarding the healthcare workforce was extracted from QUMS records. The analysis utilized two key measures, namely the Gini coefficient and the HHI, to assess the fairness of resource distribution. Data analysis was performed using Microsoft Excel 2016 and the Stata statistical software. RESULTS: The highest number of GPs, specialists, and subspecialists was observed in 2014, 2017, and 2017, respectively, while the lowest number was recorded in 2016, 2011, and 2015, respectively. From 2011 to 2017, the Gini coefficient for GPs ranged between 0.61 and 0.63. Among specialists, the lowest Gini coefficient value was observed in 2015 (0.57), while the highest was recorded in 2017 (0.60). The Gini coefficient for subspecialists remained constant at 0.52 from 2011 to 2017. The HHI revealed a high concentration of GPs in the cities of Qazvin province. Although the disparity gradually decreased in the specialties of eye, ear, nose, and throat, and pediatrics, the concentration still persists in Qazvin. In general surgery, the index value is low, indicating some level of inequality. In anesthesia and neurology, the index value decreased after the HTP and reached 5700; however, achieving equality (below 1000) still requires further efforts. No significant change in the index was observed after the HTP in specialties such as neurosurgery, rehabilitation, and nuclear medicine. Subspecialists also exhibited a concentration in the city of Qazvin. CONCLUSION: Based on the analysis of the Gini and HHI, it is evident that the distribution of GPs has not undergone significant changes following the implementation of the HTP. The Gini coefficient, which ranges from 0.4 to 0.6, indicates a high to complete level of inequality in the distribution of specialists and subspecialists. Moreover, the HHI exceeds 1000, reflecting a concentration of resources in specific areas. As a result, the HTP has not yet achieved its goal of ensuring a fair distribution of human resources. To address this issue, it is recommended to redesign distribution policies, including the allocation of physical health resources, such as specialized hospitals, beds, and medical equipment. Additionally, increasing student admissions in specialized and subspecialized fields and implementing tariff incentives can contribute to a more equitable distribution of resources. By aligning distribution policies with the principle of fairness, the healthcare system can better address the issue of resource distribution.

Performance analysis of indicators in teaching hospitals after the Health Transformation Plan: a Case Study in Iran.

BACKGROUND: This study aimed to examine the status of performance indicators in hospitals affiliated with Qazvin University of Medical Sciences (QUMS) before and after the implementation of the Health Transformation Plan (HTP). METHODS: This longitudinal descriptive-analytical study was conducted utilizing hospital data. The study collected data using a checklist that included both general characteristics of the participating hospitals and performance indicators such as "the number of outpatient visits," "the number of paraclinical patients," "the number of surgeries," and "the number of inpatients" on a monthly basis for 2012-2019. The intervention examined in this study was the implementation of the HTP in May 2014. The data collected was analyzed using interrupted time series and STATA statistical software version 15. RESULTS: The study examined seven hospitals affiliated with QUMS, including general, trauma, pediatric, gynecology, and psychiatry hospitals. The findings indicated a significant increase in outpatient visits, paraclinical patients, and inpatients in the first month after the intervention. Specifically, there was an increase of 1739 in the number of outpatient visits, an increase of 513 in the number of paraclinical patients, and an increase of 135 in the number of inpatients (p < 0.001). CONCLUSION: The HTP has improved patients' access to medical services. It achieved this by reducing out-of-pocket payments for healthcare services and implementing programs such as developing clinics, improving the quality of visits, and retaining doctors in deprived areas. The reduction in out-of-pocket payments has been particularly beneficial for individuals who lack financial resources and previously faced barriers to accessing healthcare services.

Zero-Inflated Count Regression Models in Solving Challenges Posed by Outlier-Prone Data; an Application to Length of Hospital Stay.

Introduction: Ignoring outliers in data may lead to misleading results. Length of stay (LOS) is often considered a count variable with a high frequency of outliers. This study exemplifies the potential of robust methodologies in enhancing the accuracy and reliability of analyses conducted on skewed and outlier-prone count data of LOS. Methods: The application of Zero-Inflated Poisson (ZIP) and robust Zero-Inflated Poisson (RZIP) models in solving challenges posed by outlier LOS data were evaluated. The ZIP model incorporates two components, tackling excess zeros with a zero-inflation component and modeling positive counts with a Poisson component. The RZIP model introduces the Robust Expectation-Solution (RES) algorithm to enhance parameter estimation and address the impact of outliers on the model's performance. Results: Data from 254 intensive care unit patients were analyzed (62.2% male). Patients aged 65 or older accounted for 58.3% of the sample. Notably, 38.6% of patients exhibited zero LOS. The overall mean LOS was 5.89 (± 9.81) days, and 9.45% of cases displayed outliers. Our analysis using the RZIP model revealed significant predictors of LOS, including age, underlying comorbidities (p<0.001), and insurance status (p=0.013). Model comparison demonstrated the RZIP model's superiority over ZIP, as evidenced by lower Akaike information criteria (AIC) and Bayesians information criteria (BIC) values. Conclusions: The application of the RZIP model allowed us to uncover meaningful insights into the factors influencing LOS, paving the way for more informed decision-making in hospital management.

The relationship between patient safety culture and adverse events in Iranian hospitals: a survey among 360 nurses.

BACKGROUND: Adverse events have become a global problem and are an important indicator of patient safety. Patient safety culture is essential in efforts to reduce adverse events in the hospital. This study aimed to investigate the status of the patient safety culture, the frequency of adverse events, and the relationship between them in Qazvin's hospitals in Iran. METHODS: The present study is a descriptive-analytical study conducted in six hospitals in Qazvin, Iran, in 2020. The study population was nurses working in Qazvin hospitals. We collected data via a patient safety culture questionnaire and an adverse event checklist. Three hundred sixty nurses completed questionnaires. Multiple logistic regression was used to investigate the relationship between variables. RESULTS: The highest mean of patient safety culture was related to the organizational learning dimension (3.5, SD = .074) and feedback and communication about errors (3.4, SD = 0.82). The participants gave the lowest score to dimensions of exchanges and transfer of information (2.45,=0.86) and management support for patient safety (2.62,Sd = 0.65). Management's support for patient safety, general understanding of patient safety culture, teamwork within organizational units, communication and feedback on errors, staff issues, and information exchange and transfer were significant predictors of adverse events. CONCLUSION: This study confirms patient safety culture as a predictor of adverse events. Healthcare managers should provide the basis for improving the patient safety culture and reducing adverse events through methods such as encouraging the reporting of adverse events and also holding training courses for nurses.

Evaluation of errors related to surgical pathology specimens of different hospital departments with a patient safety approach: a case study in Iran.

BACKGROUND: Most surgical specimen errors occur in the pre-analysis stage, which can be prevented. This study aims to identify errors related to surgical pathology specimens in one of the most comprehensive healthcare centers in Northeast Iran. METHODS: The present study is descriptive and analytical research conducted cross-sectionally in 2021 at Ghaem healthcare center in the Mashhad University of Medical Sciences on the basis of a census sampling. We used a standard checklist to collect information. Professors and pathologists evaluated the validity and reliability of the checklist using Cronbach's alpha calculation method of 0.89. We analyzed the results using statistical indices, SPSS 21 software, and the chi-square test. RESULTS: Out of 5617 pathology specimens studied, we detected 646 errors. The highest number of errors is the mismatch of the specimen with the label (219 cases; 3.9%) and the non-compliance of the patient's profile in the specimen sent with the label (129 cases; 2.3%), and the lowest errors are the inappropriate volume of the fixator(24 cases; 0.4%), and they accounted for insufficient sample size (25 cases; 0.4%). Based on Fisher's exact test results, there was a significant difference between the proportion of errors in different departments and months. CONCLUSION: Considering the frequency of labeling errors in the stage before the analysis in the pathology department, the use of barcode imprinted in specimen containers, the removal of the paper request for pathology, the use of radio frequency chip technology, the use of the rechecking system and improving communication in different departments can be effective in reducing these errors.

Comparing the pharmacology knowledge and performance of nurses and nursing students in the use of information resources in pediatrics wards: An observational study.

Objectives: One of the major duties of nurses is proper medication administration while maintaining patient safety, which requires sufficient knowledge and practice. Any gaps in knowledge used by nurses can lead to irreversible injury or death of the patient. This study is aimed to determine and compare the pharmacology knowledge and performance of nurses and nursing students in using the information resources in pediatrics wards. Method: This descriptive observational study was performed on 300 nurses and nursing students. Sources of knowledge and performance of nurses and nursing students were analyzed with researcher-made tools to determine their pharmaceutical knowledge, sources of knowledge, and attitudes by independent t-test, chi-square, one-way analysis of variance, Pearson, and Spearman tests. Result: Three hundred questionnaires were examined. The clinical experience of nurses and students was their most important source of information in drug challenges for 33.7% of the participants. About 24.6% of nurses obtained the required information from specialized books on pediatric medicine. About 17.1% of the participants attained their knowledge from multiple sources (e.g. various available sources such as the Internet, pharmacy books, software, and their experiences and colleagues), while electronic sources and the Internet were the sources of knowledge for 15.5% and 7.7% of the nurses, respectively. Concerning nursing students, 6.3% used books, 41.7% considered colleagues (clinical experiences), 20.8% employed electronic resources, 22.8% used the Internet, and 9.1% relied on multiple sources. There were significant differences in the knowledge and performance of the nurses based on their source of pharmacological knowledge (P < 0.05). Conclusion: Most of the resources used in the hospital are not up-to-date and evidence-base, and the majority of nurses tend to rely on their clinical experience or their collegues information for medication administration rather than reading books or searching for up-to-date approaches and information. Nursing students also trust nurses' clinical experiences more than other sources provided for them including books and Internet. Some action should be taken by the managers for boosting the nurses' tendency for using up-to-date information resources.

Burden of Transport-Related Injuries in the Eastern Mediterranean Region: A Systematic Analysis for the Global Burden of Disease Study 2017.

BACKGROUND: Transport-related injuries (TIs) are a substantial public health concern for all regions of the world. The present study quantified the burden of TIs and deaths in the Eastern Mediterranean region (EMR) in 2017 by sex and age. METHODS: TIs and deaths were estimated by age, sex, country, and year using Cause of Death Ensemble modelling (CODEm) and DisMod-MR 2.1. Disability-adjusted life years (DALYs), which quantify the total burden of years lost due to premature death or disability, were also estimated per 100000 population. All estimates were reported along with their corresponding 95% uncertainty intervals (UIs). RESULTS: In 2017, there were 5.5 million (UI 4.9-6.2) transport-related incident cases in the EMR - a substantial increase from 1990 (2.8 million; UI 2.5-3.1). The age-standardized incidence rate for the EMR in 2017 was 787 (UI 705.5-876.2) per 100000, which has not changed significantly since 1990 (-0.9%; UI -4.7 to 3). These rates differed remarkably between countries, such that Oman (1303.9; UI 1167.3-1441.5) and Palestine (486.5; UI 434.5-545.9) had the highest and lowest age-standardized incidence rates per 100000, respectively. In 2017, there were 185.3 thousand (UI 170.8-200.6) transport-related fatalities in the EMR - a substantial increase since 1990 (140.4 thousand; UI 118.7-156.9). The age-standardized death rate for the EMR in 2017 was 29.5 (UI 27.1-31.9) per 100000, which was 30.5% lower than that found in 1990 (42.5; UI 36.8-47.3). In 2017, Somalia (54; UI 30-77.4) and Lebanon (7.1; UI 4.8-8.6) had the highest and lowest age-standardized death rates per 100,000, respectively. The age-standardised DALY rate for the EMR in 2017 was 1,528.8 (UI 1412.5-1651.3) per 100000, which was 34.4% lower than that found in 1990 (2,331.3; UI 1,993.1-2,589.9). In 2017, the highest DALY rate was found in Pakistan (3454121; UI 2297890- 4342908) and the lowest was found in Bahrain (8616; UI 7670-9751). CONCLUSION: The present study shows that while road traffic has become relatively safer (measured by deaths and DALYs per 100000 population), the number of transport-related fatalities in the EMR is growing and needs to be addressed urgently.

Make Intelligent of Gastric Cancer Diagnosis Error in Qazvin's Medical Centers: Using Data Mining Method.

Objective: Gastric cancer is one of the most common types of cancers, which will result in irreparable harm in the case of misdiagnosis or late diagnosis. The purpose of this study is to investigate the capability of data mining techniques and disease risk factor characteristics to predict and diagnose the gastric cancer. Methods: In this retrospective descriptive-analytic study, we selected 405 samples from two groups of patient and healthy participants. A total of 11 characteristics and risk factors were examined. we used four Machine learning methods, Include support vector machine (SVM), decision tree (DT), naive Bayesian model, and k nearest neighborhood (KNN) to classify the patients with gastric cancer. The evaluation criteria to investigate the model on the database of patients with gastric cancer included Recall, Precision, F-score, and Accuracy. Data was analyzed using MATLAB® software, version 3.2 (Mathworks Inc., Natick, MA, USA). Results: Based on the results achieved from the evaluation of four methods, the accuracy rates of SVM, DT, naive Bayesian model, and KNN algorithms were 90.08, 87.89, 87.60, and 87.60 percent, respectively. The findings showed that the highest level of F-Score was related to the SVM (91.99); whereas, the lowest rate was associated with the KNN algorithm (87.17). Conclusion: According to the findings, the SVM algorithm showed the best results in classification of Test samples. So, this intelligent system can be used as a physician assistant in medical education hospitals, where the diagnosis processes are performed by medical students.

Role of Organizational Climate in Job Involvement: A Way to Develop the Organizational Commitment of Nursing Staff.

Employees are the most valuable assets of an organization; therefore, it is very important to understand their behavior. In this regard, the present study was carried out in order to examine the effect of organizational climate on job involvement among nurses working in the teaching hospitals of Qazvin Province, Iran. The present descriptive analytical study was done in 2017. To randomly select a specific proportion of nurses from each of Qazvin teaching hospitals, stratified sampling was used. In total, 340 nurses were selected. Data were collected using 3 questionnaires: Halpin and Kraft Organizational Climate Questionnaire, Job Involvement Questionnaire (Kanungo), and Allen and Myer Organizational Commitment Questionnaire. For data analysis, confirmatory factor analysis and structural equation modeling were used applying AMOS-24 software. The results of path analysis showed the effect of organizational climate on the nurses' job involvement. Moreover, organizational climate influenced organizational commitment through the mediation of job involvement. According to values obtained for degree of freedom based on chi-square, goodness-of-fit index, root mean square error of approximation, and comparative fit index were in the defined range; therefore, the validity of the conceptual model was approved.

They were selected by a multistage stratified sampling method. The study instruments were Stinemetz Standard Job Stress Questionnaire and Hospital Survey on Patient Safety Culture (HSOPSC). After the required data were collected, they were analyzed using descriptive and inferential statistical methods (Pearson correlation, independent-samples t-test, and ANOVA) through SPSS version 23. RESULTS: The results of the present study showed that 75% of the nurses experienced average and high levels of stress. Among different dimensions of safety culture, organizational learning and handoffs and transitions obtained the highest and the lowest scores, respectively (72.5 and 24.5). The mean score of safety culture dimensions was 51.52. The results of the Pearson correlation test showed that there was a direct significant relationship between different dimensions of safety culture among nurses and the level of stress (p≤0.05). CONCLUSION: According to the findings, patient safety should be considered as a strategic priority for the senior managers of the health system. In order to enhance patient safety, managers should pay special attention to evaluating safety culture in organizations that deliver health service, especially hospitals.
