    The aim of the study was to investigate the possibility of using supervised statistical models to assess burn injury patterns, outcomes and their interrelationship. Using burn study data, a preliminary principal component analysis was carried out and two separate clusters were observed. Observations were split into two classes and analysed by partial least squares (PLS) regression discriminant analysis to assess possible predictors of each class. To assess predictors of total body surface area burned (TBSA), the orthogonal projections to latent structures (OPLS) model was used after PLS regression. The identified classes were later designated as high-risk burn victims and low-risk burn victims. Female gender fell into the high-risk class. Many possible predictors were found to be associated with burn injury extent, after modelling the natural logarithm of TBSA by OPLS. The fitted model explained 76% of variation in Y. It excluded up to 9% of orthogonal variation captured in two orth...

    Burn injuries are considered one of the most preventable public health issue among children; however, are a cause of significant morbidity and mortality in Iran. The aim of this study was to assess individual-level predictors of severe burn injuries among children leading to hospitalization, in East Azerbaijan Province, in North-West of Iran. The study was conducted through a hospital based case-control design involving 281 burn victims and 273 hospital-based controls who were frequency matched on age, gender and urbanity. Both bivariate and multivariate methods were used to analyze the data. Mean age of the participants was 40.5 months (95 % CI: 37-44) with the majority of burns occurring at ages between 2 months-13.9 years. It was demonstrated that with increase in the caregiver's age there was a decrease in the odds of burn injuries (OR = 0.94, 95 % CI: 0.92-0.97). According to the multivariate logistic regression there were independent factors associated with burn injuries i...

    Abstract: Background: This study systematically reviewed the literature in order to determine the effect of Attention-Deficit Hyperactivity Disorder (ADHD) on injuries and assessed the magnitude of the potential association. Methods: A systematic review of the studies examining the association of ADHD and injuries was carried out across multiple databases. Odds ratios and standardized mean differences were pooled. Results: A total of 35 studies were selected for quantitative analysis. The association of ADHD and injuries was confirmed over the meta-analysis of eligible studies. The odds ratio pooled over all comparative studies was 1.96(95% CI: 1.6-2.4) using random effects model. Pooled odds ratio of 2.1 and 2.17 were calculated respectively when cohort and case-control studies or just cohort studies were included. The pooled odds ratio reduced to 1.8(CI:1.45-2.3) when studies on specific injuries were removed. For studies comparing scores of rating scales, the pooled standardized ...

    s Background The aim of this study was to investigate the association between adult ADHD screening scores and hospitalization due to pedestrian injuries in a sample of Iranian pedestrians. Methods Through a case-control study, a case population of 177 pedestrians injured by the vehicles in road traffic crashes were compared with 177 controls who lacked a record of intentional or unintentional injuries enrolled from various wards of Imam Reza University Hospital which is a specialty teaching hospital located in the same city with similar referral level. The cases and controls had an age range of 18–65 years and were matched on gender and age. ADHD symptom profile was assessed using the Persian Self-report Screening Version of the Conner’s Adult ADHD Rating Scales (CAARS-S:SV). The association of ADHD screening score and pedestrian injuries was investigated using multiple binary logistic regression to investigate the independent effect of ADHD index score on belonging to case group.

    Background Scientific misconduct is a prevalent phenomenon with many undesirable consequences. In Iran, no original research have been done about scientific fraud. So, this study aimed at describing a challenging research misconduct in Iran, its related causes, and the ways Iranian authorities deal with it. Methods In this cross-sectional study, through a two-year period, all the advertisements installed in the study sites were collected and the content analysis was performed. Semi-structured interviews were held with experts for discovering the causes of misconduct. Also, published issues were collected for review of the laws on confronting the fraud in Iran. Results The content analysis resulted in identifying four categories of misconduct issues: advertising approach, types of services, outcome guarantee, and justifying the academic credit. Besides, reviewing the related literature indicated that Iranian government and the responsible authorities have recently established serious...

    Background: To model, the predictors of injuries caused the hospitalization of motorcyclists using a hybrid structural equation modeling-artificial neural network (SEM-ANN) considering a conceptual model.Methods: In this case-control study, 300 cases and 156 controls were enrolled using a cluster random sam- pling. The cases were selected among injured motorcyclists in refereed to Imam Reza Hospital and Tabriz Shohada Hospital, Tabriz, Iran since Mar 2013. The predictability of injury by motorcycle-riding behavior questionnaire (MRBQ), Attention-deficit/hyperactivity disorder (ADHD) along with its subscales and motor- cycle related variables was modeled using SEM-ANN. By SEM, linear direct and indirect relationships were assessed. To improve the SEM, the ANN was utilized sequentially to account for the nonlinear and interaction effects that is not supported by SEM.Results: The predictors of injury were: MRBQ, ADHD, and its subscales, marital status, education level, rid- ing for fun...

    Our aim in this survey was to explore descriptive epidemiology of injuries in Tehran in 2012 and to report the recalled estimates of injury incidence rates. A population survey was conducted in Tehran during 2012, within which a total of 8626 participants were enrolled. The cluster sampling was used to draw samples in 100 clusters with a pre-specified cluster size of 25 households per cluster. Data were collected on demographic features, accident and injury characteristics based on the International Classification of Diseases (ICD10). A total of 618 injuries per 3 months were reported, within which 597 cases (96.6%)were unintentional injuries. More than 82% of all injuries were those caused by exposure to inanimate mechanical forces, traffic accidents, falls and burns. Above 80% of the traffic injuries happened among men (P<0.001). About 43% of the unintentional injuries were mild injuries.After the age of 40, women, unlike men, had higher risks for being injured. The estimated a...

    In 2015, it was estimated that the burden of disease in Iran comprised of 19 million disability-adjusted life years (DALYs), 74% of which were due to non-communicable diseases (NCDs). The observed leading causes of death were cardiovascular diseases (41.9%), neoplasms (14.9%), and road traffic injuries (7.4%). Even so, the health research investment in Iran continues to remain limited. This study aims to identify national health research priorities in Iran for the next five years to assist the efficient use of resources towards achieving the long-term health targets. Adapting the Child Health and Nutrition Research Initiative (CHNRI) method, this study engaged 48 prominent Iranian academic leaders in the areas related to Iran's long-term health targets, a group of research funders and policy makers, and 68 stakeholders from the wider society. 128 proposed research questions were scored independently using a set of five criteria: feasibility, impact on health, impact on economy, ...

    To study the epidemiology of car user road traffic fatalities (CURTFs) during eight years, in East Azerbaijan, Iran. A total of 3051 CURTFs registered in East Azerbaijan forensic medicine organization database, Iran, during 2006-2014, were analyzed using Stata 13 statistical software package. Descriptive statistics (<0.05) and inferential statistical methods such as Chi-squared test and multivariate logistic regression with <0.1 were applied. Of the 7818 road traffic injury (RTI) deaths, 3051 (39%) were car users of whom 71% were male (mean age of 36.7±18.5 years). The majority of accident mechanisms were vehicle-vehicle crashes (63.95%), followed by rollover (26.24%). Crash causing vehicle fall increased the pre-hospital death likelihood by 2.34 times. The prominent trauma causing death was head trauma in 62.5%). In assessing the role of type of counterpart vehicle on pre-hospital mortality, considering the other cars to be the reference group for comparison, deceased victims...

    To investigate epidemiological aspects of injuries among Iranian children under 7 years of age using obtained data from a national registry. Injury data were derived from a national-based injury supervision system during 2000-2002. This registry involved all of home-related injuries for children less than 7 years of age that treated in health or emergency centers. The study population included 25% of Iranian people. The descriptive statistical methods were used for representing the distribution of the variables like age, sex, injury mechanisms, types of injuries, etc. Data were presented as mean ± SD and proportions as appropriate. Of the total 307,064 domestic injuries registered during 2000-2002, 77,500 cases (25.2%) were children. 70% of these children (54581 cases) were in age group of 1-5 years. The large fraction (58.8%) of injuries among children under 7 years of age went back to burn injuries. Cuts and lacerations were at the second level with 17.4%. 51% of injuries had cont...

    ABSTRACT Background: Evaluating the performance in clinical governance activities requires specific and appropriate national indicators. The aim of this study was to develop clinical governance performance indicators in dimensions of risk management and clinical effectiveness using viewpoints of healthcare staff who were working in various hospitals in East Azerbaijan, Iran. Materials and Methods: Through an extensive literature review, 135 indicators were selected for assessment by using comments of the staff working in all 41 hospitals of East Azerbaijan. Two hundred and eighty-eight people participated in four sessions in National Public Health Management Center (NPMC). Participants evaluated the indicators through 36 Focus Group Discussions. Through their discussions they completed predesigned forms with respect to title of indicators, methods of calculating the indicators, total score of importance and its feasibility, data collection method, data sources, and the level of indicator's evaluation. Results: Patients' safety and cardiovascular care unit (CCU) each by 16 indicators had the highest number of indicators. Pathology, ophthalmology, and radiology each by three indicators had the lowest number of indicators. The median score of the importance and the feasibility were both calculated in eight. Only 36.3% of the indicators were collected from hospitals. Most of the suggestions for gathering the indicators were from medical records and hospital information system (HIS), supervisors, statisticians, and admissions department. Sixty-nine indicators were designed by the participants that patient's safety had the highest number of them. Conclusion: A total of 204 indicators were evaluated and proposed by hospitals staff and stakeholders in clinical governance that can be useful in the quality of hospitals services promotion.

    Nowadays, it is well known that the attention-deficit/hyperactivity disorder (ADHD) is not confined to children and adolescents. Recent data showed that a considerable portion of the general adult population may be affected by ADHD. On the other hand, the impact of ADHD on driving performance, a major area of adult life, has gained enthusiasm. More recent studies revealed an association between adult ADHD and undesirable driving problems. This study was performed to determine the association between presence of adult ADHD and traffic injuries. In this case-control study, in a 13 month period, 140 subjects (70 drivers/riders injured in traffic accidents, and 70 age- and sex-matched non traumatic controls) were selected to participate in the study and were placed in two groups. Subjects with psychiatric comorbidities were excluded. The Conners' Adult ADHD Rating Scale (CAARS) self-report (screening version) was used for screening adult ADHD in both groups. Finally, the occurrence ...

    ABSTRACT Background: Stroke is the second leading cause of death and the most important cause of adult disability worldwide. Ischemic stroke, Intracerebral hemorrhage (ICH), and Subarachnoid hemorrhage (SAH) are the most common subtypes of stroke. Risk factors in each subtype are different and there are limited data in this regard in Iran. Thus, the present study was designed to fill this gap. Methods: In a retrospective analytic study done at two university tertiary referral hospitals in the northwest of Iran, Imam-Reza and Razi hospitals,from March 2008 to April 2013, Patients with diagnosis of stroke were enrolled. Risk factors and stroke subtypes were recorded for all the patients. Risk Factors for each subtype were recorded separately. Results: A total number of 5355 patients enrolled in the present study. Final diagnosis of ischemic stroke was made in 76.5% of the patients, as were intra cerebral with or without intra ventricular hemorrhage (ICH + IVH), 14.3% and subarachnoid hemorrhage (SAH) 9.2% of the patients, respectively. Risk factors for each subtype were: Ischemic Stroke: Hypertension: 70%, Diabetes mellitus: 26.40%, Smoking:13.20%, Hyperlipidemia: 12.7%, ICH (with or without IVH):Hypertention: 69.1%, Diabetes mellitus: 14.5%, Smoking: 10.9%, Hyperlipidemia:6.8%, AF: 1.0%. SAH: Hypertention: 53.8%, Diabetes Mellitus:10.7%, Smoking 12.1%, Hyperlipidemia:5.5%, AF:0.4%. Conclusions: This study suggests similar rates of hypertension in the ischemic stroke and ICH patients. Atrial fibrillation and DM were significantly prevalent in the ischemic stroke patients.

    Evidence-based medicine (EBM) has emerged as an effective strategy to improve health care quality. The aim of this study was to systematically review and carry out an analysis on the barriers to EBM. Different database searching methods and also manual search were employed in this study using the search words ('evidence-based' or 'evidence-based medicine' or 'evidence-based practice' or 'evidence-based guidelines' or 'research utilization') and (barrier* or challenge or hinder) in the following databases: PubMed, Scopus, Web of Knowledge, Cochrane library, Pro Quest, Magiran, SID. Out of 2592 articles, 106 articles were finally identified for study. Research barriers, lack of resources, lack of time, inadequate skills, and inadequate access, lack of knowledge and financial barriers were found to be the most common barriers to EBM. Examples of these barriers were found in primary care, hospital/specialist care, rehabilitation care, medical education, management and decision making. The most common barriers to research utilization were research barriers, cooperation barriers and changing barriers. Lack of resources was the most common barrier to implementation of guidelines. The result of this study shows that there are many barriers to the implementation and use of EBM. Identifying barriers is just the first step to removing barriers to the use of EBM. Extra resources will be needed if these barriers are to be tackled.

    Burns are one of the leading causes of injury-related deaths in Iran. We conducted a study to investigate features of burns in rural areas of Ardabil Province from October 2004 through March 2005, with an aim to providing content for effective prevention programs. This study employed longitudinal prospective methodology. The study population included all patients presenting with burns to local health care facilities during the study period. A total of 1179 cases were studied. Most of the cases (59.4%) were females. Mean of age of victims was 22.3+/-19 years in females and 13.6+/-17 years in males. The vast majority (91.2%) of burns occurred at home. More than two-thirds of burns were because of hot liquids or steam. The majority of scald burns resulted during use of heating devices such as samovars, gas stoves, valors and picnic gas stoves. Overturning and spilling of hot liquids were the most common injury mechanisms. Prevention programs should focus on children and adult women. Prevention efforts should target home environments and focus on prevention of scalding burns.
