Abstract	Background: Non-alcoholic fatty liver disease (NAFLD) can lead to serious complications and have adverse effects on physical and mental well-being in young people. This review aimed to investigate the prevalence of NAFLD among Iranians aged 6 to 18 years. Materials and Methods: This study was conducted by systematic review and meta-analysis methods. A detailed search was performed on various international and Iranian databases from January 2000 to January 2023. The international databases included Pubmed, Scopus, Embase, and Web of Science, while the Iranian databases consisted of MagIran and SID. The quality of the selected studies was assessed using the Newcastle-Ottawa Scale. Overall prevalence was estimated using the random-effects model and DerSimonian and Laird criteria with a 95% confidence interval. The Q-Cochrane test and the I2 index were used to assess heterogeneity between studies. In addition, a sensitivity analysis was performed to ensure the reliability of the results. Data analysis was performed in Stata12 software. Results: Finally, 9 studies were selected for analysis, of which, 7 studies were of good quality, while 2 studies were of average quality based on the assigned scores. According to the random-effects model, the overall prevalence of NAFLD in Iranian individuals aged 6 to 18 years was 35% with a 95% confidence interval (24% to 46%). Conclusion: The results of our study revealed a high prevalence of NAFLD in Iranian individuals aged 6 to 18 years. Policymakers and healthcare planners in Iran must implement educational programs aimed at the prevention and early diagnosis of this disease.

Abstract	Background Computed tomography (CT) scan is a common imaging technique used to evaluate the severity of a head injury. The overuse of diagnostic interventions in the health system is a growing concern worldwide. Objectives: The aim of this systematic review is to investigate the rate of CT scan overuse in cases of mild head injury. Methods Eligibility criteria: We encompassed observational studies-either designed as cohort, case-control, or cross-sectional investigations-that reported on CT scan overuse rates for mild head injuries. Studies had to be published in peer-reviewed, English-language sources and provide full content access Information sources: Web of Sciences, Scopus, Medline via PubMed, the Cochrane Library and Embase were searched from inception until April 1, 2023. Studies were included if reporting the overuse of CT scans for mild head injuries using validated criteria. Risk of bias: We used the Risk Of Bias In Non-randomised Studies - of Interventions (ROBINS-I) tool to evaluate the risk bias assessment of included studies. Two independent reviewers evaluated the eligibility of studies, extracted data, and assessed study quality by using the Newcastle-Ottawa Scale. Synthesis of results: Overuse estimates were calculated using a random-effects model. Subgroup analyses were performed to investigate any sources of heterogeneity. Point rate of overuse of CT scans for mild head injuries was the main outcome measured as percentage point estimates with corresponding 95% CIs. Results Included studies: Of the 913 potentially relevant studies identified, eight studies were selected for the final analysis. Synthesis of results: The pooled rate of CT scan overuse in patients with mild head injury was found to be 27% [95% CI: 16-43; I2 = 99%]. The rate of CT scan overuse in mild head injury cases varied depending on the criteria used. The rate of CT scan overuse was 37% [95% CI: 32-42; I2 = 0%] with the Glasgow Coma Scale (GCS), 30% [95% CI: 16-49; I2 = 99%] with the Canadian computed tomography head rule, ...

Abstract	Background: Physiological childbirth refers to the natural birthing process that does not involve medical or pharmaceutical interventions. This method is characterized by spontaneous labor, the absence of medical interventions, freedom of movement, and active participation of the mother. Rate of cesarean delivery has been increasing over the past decade in Iran, accounting for approximately 50% of all births in the country as Iranian healthcare officials have also promoted physiological childbirth. In this regard, it is important to recognize that physiological birth is a personal choice; therefore, women should receive the necessary information and support to make informed decisions about their birth experiences. Besides, it is critical to provide the necessary education for healthcare providers and engage with women to address their cultural and social beliefs about childbirth. Additionally, the supportive policies of the government that promote physiological childbirth and educational programs can also be valuable in this regard.

Abstract	There is little data on direct medical costs and how to overcome the shock introduced by the novel Coronavirus (COVID-19) which emerged in Wuhan, China. The aim of this report is to present the methodology of an observational study for analyzing the resource utilization and direct medical costs of hospitalization. A multicenter retrospective observational study will be conducted on hospitalized patients with COVID-19 in selected hospitals of Tehran University Medical Sciences from February 2020 to June 2020. Cost calculations will be based on micro-costing approaches according to the health insurance perspective. Demographic, clinical, and cost data for the aforementioned patients will be collected through reviews of medical and financial records using a self-made questionnaire categorized in three parts (Form No. 1). The first part consists of demographic characteristics, the second part includes clinical information (e.g., symptoms, comorbidities, and complications), and the third part consists of resource utilization and cost data. Descriptive statistics (means, frequencies, percentages, and 95% confidence intervals) will be used to report data. With this report we sought to provide a valuable framework for estimating the direct medical costs of COVID-19 for hospitalized-patients basis on the severity of presentation. This will be the core for an assessment of the economic burden of COVID-19 in different presentations of the disease.

Abstract	Background and Objectives : Due to unique characteristics of the health sector, measuring the efficiency and quality of services provided are the top priorities of the Ministry of Health and Medical Education. In health systems, an appropriate response to the needs and demands of patients is a priority. This study was conducted to assess hospital’s services quality using logit model for prioritizing service attributes based on patients’ perception in 2012. Material and Methods : In this descriptive cross-sectional study, 330 patients in Imam Khomeini Hospital in Tehran were entered into the study based on Cochran method. Data were gathered using questionnaire in 5 dimensions and 10 scenarios. Reliability and validity of the questionnaire were approved. Data were input into STATA software 10th edition and utility function was estimated to calculate the marginal utility specifications. Results : According to the patients’ perception, type of examination and treatment was ranked as the first and cleaning services of the departments and toilets was ranked as the last priority. The results about waiting time between hospital arrival until admission was negative which means reverse influence on patient perception of quality. Except cleaning services of the departments and toilets and handling patients, other features had significant relationship with patient preferences. Conclusion : In order to increase the desirability of visiting patients in hospitals and delivering high quality services and considering patient preferences; hospital administrators need to be focused on improving the quality of the programs.

Abstract	Background Health systems need to prioritize their services, ensuring efficiency and equitable health provision allocation and access. Alongside, health technology assessment (HTA) seeks to systematically evaluate various aspects of health technologies to be used by policy- and decision-makers. In the present study, we aim to identify strengths, weaknesses, opportunities, and threats in developing an HTA in Iran. Method This qualitative study was conducted using 45 semi-structured interviews from September 2020 to March 2021. Participants were selected from key individuals involved in health and other health-related sectors. Based on the objectives of the study, we used purposive sampling (snowball sampling) to select individuals. The range of length of the interviews was between 45 to 75 minutes. Four authors of the present study carefully reviewed the transcripts of interviews. Meanwhile, the data were coded on the four domains of strengths, weaknesses, opportunities, and threats (SWOT). Transcribed interviews were then entered into the software and analyzed. Data management was performed using MAXQDA software, and also analyzed using directed content analysis. Results Participants identified eleven strengths for HTA in Iran, namely the establishment of an administrative unit for HTA within the Ministry of Health and Medical Education (MOHME); university-level courses and degrees for HTA; adapted approach of HTA models to the Iranian context; HTA is mentioned as a priority on the agenda in upstream documents and government strategic plans. On the other hand, sixteen weaknesses in developing HTA in Iran were identified: unavailability of a well-defined organizational position for using HTA graduates; HTA advantages and its basic concept are unfamiliar to many managers and decision-makers; weak inter-sectoral collaboration in HTA-related research and key stakeholders; and, failure to use HTA in primary health care. Also, participants identified opportunities for HTA development in Iran: support from the ...
