Background: Quality of work life depends on a combination of variables in the work environment that has an important impact on organizational commitment, work participation, and job performance. Therefore, measuring two variables of quality of work life and organizational commitment is important for all employees of organizations, including emergency nurses, who are important members of the health service community. This study aimed to determine the relationship between quality of work life and organizational commitment among Iranian emergency nurses. Materials and Methods:A descriptive and correlational study was conducted in 2016. The study population included all emergency nurses working in one of the hospitals of Kerman Province, Iran. The data collection tool was the personal and occupational questionnaire, Walton quality of work life questionnaire, and Allen and Meier organizational commitment questionnaire. Data analysis was performed by using descriptive tests, the Pearson correlation and ANOVA statistics tests in SPSS V. 23. Results:The results showed that the quality of work life has a positive and significant relationship (r=0.49, P=0.017) with organizational commitment. More specifically, quality of work life is related to emotional commitment (r=0.44, P=0.001), normative commitment (r=0.40, P=0.003) and continuous commitment (r=0.33, P=0.015). Conclusion:Since the higher quality of work life brings more commitment for employees, managers can improve the essential components of working life quality of nurses by adopting appropriate solutions, and providing the necessary conditions for improving the quality of service provision and productivity.

BACKGROUND: The prevalence of viral diseases is on the rise and has caused many problems for public health. COVID-19 is a new viral outbreak in the world. This study aimed to investigate the trends of incidence and case fatality rate (CFR) of COVID-19 in the world by April 30, 2020. METHODS: This was a descriptive-analytical study. We investigated the number of cases and deaths in 35 selected countries and regions of the WHO that had at least 10,000 cases by the time of the study. In addition, the incidence and CFR of COVID-19 were investigated. Finally, time trends of the number of cases, deaths, and CFR were investigated using ordinary least squares regression models. RESULTS: The total number of confirmed cases of COVID-19 was 3,090,184. The European region had the highest number of COVID-19 patients (1,434,649 [46.43%]). Ukraine with 10,406 and the USA with 1,003,974 cases have reported the lowest and highest confirmed cases, respectively. In addition, the European region and the African region with 157.13 and 2.50 patients per 100,000 population had the highest and the lowest incidence rate, respectively. India (2.44) and Spain (455.69) had the lowest and the highest incidence rate per 100,000 population, respectively. In the world, 217,759 deaths have happened, of which 135,961 (62.44%) were reported in the European region. Furthermore, the USA had the highest number of deaths (52,428) due to COVID-19. CFR was 7.05% in the world, which ranged from 3.74% in the African region and 9.48% in the European region. The number of patients and deaths due to COVID-19 had increasing trends in all countries, and the trend of CFR just for Iran and Ukraine was negative. CONCLUSION: The countries had different trends in the morbidity and mortality of COVID-19. However, regarding the increasing trend of the disease in the world, it will be more important to rely on public prevention strategies. It is necessary to apply and continue public health policies at national and global levels till the control of the disease.

Background: The first cause of death and disability constituting to the burden of disease in Iran has been accident and injury incidents. Young people are more at risk, these accidents have a negative effect on the national gross domestic product (GDP), on the one hand, and they increase the costs of the health system on the other hand. Therefore, this study aimed to analyze the costs and epidemiological pattern of accidents. Methods: The study variables in the first 8 months of 2016 included from Tehran Province, Iran; age, sex, how to transfer to the hospital, consequences of an accident, the injured area, and costs. Overall, 400 cases were investigated by referring to the patients` files and deriving the intended data. SPSS software used to analyze the data and statistical tests of t-test and ANOVA were applied. Results: Most accidents have happened in summer months of Jun, Jul and Aug. Most of the files (48%) were related to the age group of 16-30. The mean cost was 9024.82 dollar. In total, 39% of the road accidents had occurred by motorcycle and 90.8% of the patients discharged from the hospital. Conclusion: Since about half of the traffic accidents were related to the age of 16 to 30 who were the active population of a community, therefore, any disability or death in these groups could cause an economic burden on the community and increase DALY. Thus, it appears essential to develop proper programs such as education for appropriate driving and strict rules for giving driving license to these ages.

Background: A huge portion of health expenditure is attributed to hospital services. Thus, it is important to use the resources appropriately. Many studies have measured inappropriate admissions and hospitalizations. The aim of this study was to review them systematically and determine the pooled quantity as well as the reasons behind such admissions and hospitalizations.Methods: PubMed, Scopus, Web of Science, Google scholar, and internal databases such as Sid, Magiran, and Barkat were searched in January 2018. Moreover, the grey literature was also performed. All studies which had assessed the appropriateness and inappropriateness of services were included. Newcastle-Ottawa scale was used for quality appraisal. I2 test, subgroup analysis, metaregression, and sensitivity analysis were performed. STATA was used for analysis. There was neither time limitation nor language limitation. The registration number in PROSPERO is CRD42019123401.Results: Of 1576 studies, 15 met the inclusion criteria. The number of medical files ranged from 198 to 1815. Most of the studies ( 14) were performed in teaching hospitals. AEP was the most frequent tool for assessing inappropriateness of the services. The pooled inappropriate admission and hospitalization were 11% (95% CI= 8% -14%)) and 13 % (95% CI= 10%-16%)), respectively. The most important determinants for inappropriate hospitalizations were attributed to physicians. Conclusion:A huge portion of health care services is inappropriate. Thus, it is highly recommended to monitor physicians more than before, as the more they are monitored, the less inappropriate the delivered services will be.
