Background and purpose: To determine an appropriate financial model for the health system of Iran, several studies have been conducted. But it seems that these studies were not comprehensive and further investigation is required. So to design a valid and enforceable mechanism, the study of policy interventions will be considered through consensus of all stakeholders. This investigation was done to determine the necessary policies and internal interventions for health care system financial improvement in Iran.Materials and Methods: The present work was carried out through investigating all key stakeholders in the medical system and the related sectors in Iran, along with the analysis of internal and external communication by using SWOT and STEEP.V methods.Results: Strategic management of health-care costs, the development of a new financial system, clarity of costs, benefiting from health national accounts, the regulation of budget based on operations, preparing the credit of per capita from prepayment and risk accumulation, the development of referral systems and mechanisms, the establishment of public fund for services purchase, preventing the involvement of insurances in non-insurance cases, competing services with the private sector and increasing resources for the promotion of equality level have been determined as the key proposed interventions.Conclusion: It seems that the interventions based to the development of improving health financial system including the deployment of full accrual basis instead of cash basis, preparing and using services cost and operational budgeting and finally, cost management and productivity are the prerequisites of reforming health financial system.

Background and purpose: Disposal of sludge from industrial wastewater treatment plants (IWWTPs) is a serious issue because it can affect human and animals’ health, and also environmental quality. In this study, sludge from a petrochemical wastewater treatment plant was analyzed regarding its physicochemical characteristics and disposal options.Materials and Methods: Grab sampling was used to collect 12 sludge samples biweekly (May-October 2012). One sample T-test was applied to analyze the obtained data. Canadian Soil Quality Guidelines (CSQG) and New Jersey Department of Environmental Protection Soil Cleanup Criteria (NJDEPSCC) were used to discuss the disposal fate of the generated sludge.Results: The results showed that the order of the studied metals in the sludge was as: Fe>Al>Zn>Cr>Pb>Ni>Cd>Co>Cu>Mn>As>Hg. It was found that generated sludge compared with CSQG is not suitable for residential/parkland, agricultural, commercial and industrial applications. But compared with NJDEPSCC, studied sludge was suitable for residential and nonresidential applications.Conclusion: According to NJDEPSCC the studied sludge has potential to be used for residential and non-residential purposes.

Background and purpose: Fluoride is one of the fundamental and required components in human body. The current study intends to survey the status of fluoride in drinking water supplies (underground water source and drinking water) in Qaemshahr city from 2006 (march/21) to 2012 (march/19) and comparison with universal standards, national and climatic conditions.Materials and Methods: This is a descriptive and sectional study. Samples were experimented in Qaemshahr water and wastewater department laboratory. Fluoride concentration in samples has been measured by DR 2800 and SPADNS Fluoride Reagent Solution. Results were analyzed with Excel software. The medium of maximum temperature in different seasons has been obtained from meteorology department. Then fluoride levels in several years have been compared to each other and to universal, national and climatic standards.Results: Comparing to standards National standards of IRAN and according to climatic conditions, proper levels of fluoride were in underground water sources respectively (9% - 0.9%) in spring, (17% - 6.5%) in summer and, (13% - 0.00%) in autumn and in winter. Also in Urban water distribution network were respectively (3.2% - 3.2%) in spring, (12.5% - 5%) in summer, (8.3% - 0.00%) in autumn and, (0.00% - 0.00%) in winter. The Fluoride levels in 100% of samples were lower than standards (MCLG and MCL=4 mg/l).Conclusion: No significant relation was observed between fluoride concentrations obtained in different seasons and in different years. In most cases the Fluoride levels in studied city were lower than universal standards, national and climatic conditions. It is recommended that adding fluoride to food chain of the studied citizens should be noticed by the relevant authorities.

Background and purpose: Since 2005, a reform known as Rural Insurance and Family Medicine Scheme has introduced to primary health care network in Iran in rural areas and small towns. The content of the reform implies a substantial change in those aspects of health centers that mainly could be categorized as structural quality. Although, this is the requirement of all health care providers, they are not identical in those items. In this article, we have tried to report the relation between structural quality of health centers and utilization of curative care in Mazandaran province.Materials and Methods: This was a cross-sectional study conducted in 2013. Secondary and routinely collected data was used to answer the research questions. The source of original data was provincial health authority’s data set. A check list containing pre-identified variables was used to extract the data. Using SPSS software package, regression analysis was run to measure the role of different independent variable on dependent variable.Results: There were 215 rural health centers affiliated to 16 cities or small towns that the reform has taken place. The outreach area population of these health centers was 1,330,212 of which 834,189 (62.71%) were covered by rural insurance solely. Health centers are not identical in terms of the characteristics of health centers and their utilization. Among the variables with significant impact on the utilization of outpatient care, except for number of physician in each health centre and existence of state owned pharmacy that were found in some health centers, the rest of variables had significant positive impact on the demand for physician visit.Conclusion: Structural quality has significant impact on the utilization of curative care of primary healthcare units at rural area in Iran. The reform seems well targeted the quality improvement and utilization of effective primary health care.

Background and purpose: The movement of spiritual leadership is a special kind of service-centered leadership which looks forward to progress and staff control.

Therefore, this study investigated the relation between spiritual leadership and job involvement of employees in the selected hospitals located in Isfahan.Materials and Methods: This study was descriptive–analytical and was conducted in 7 hospitals of Isfahan in 2010. The instrument used was a valid and reliable questionnaire consisting of three parts of demographic data, spiritual leadership questionnaire, and job involvement. Data was analyzed by SPSS .18 and analytical and descriptive statistics (t-test, ANOVA and Pearson correlation) were performed.Results: Results showed that the average score of spiritual leadership and job involvement in entire hospital cases were more than 3. There was a direct correlation between spiritual leadership and job involvement. Also there was a significant relation between the staff work experience and the two studied components.Conclusion: According to the results, it is recommended that organizations authorities involved in health issue provide conditions in addition to focusing on various aspects of spiritual leadership so that the health community rights and especially the staff of this sector be respected and have a sense of job security so that more improvement of job commitment and job involvement be provided for people by enjoying social supports.

Background and purpose:The 2-chlorophenol (2-CP) and 4-chlorophenol (4-CP) are phenolic compounds which they may have adverse effects on human and environment. Therefore, the removal of these compounds is necessary from water and wastewater. The aim of this study was the investigation of 2-CP and 4-CP removal by using Azolla filiculoides biomass.Materials and Methods: The Azolla biomass was sun dried, crushed and sieved to particle sizes in range of 1-2 mm. Then treated with 0.1M HCl for 5h followed by washing with distilled water and it used as adsorbent. The residues concentration of 2-CP and 4-CP was measured by spectrophotometer in lmax of 274 and 280 nm, respectively.Results: The solute removed increased with increasing of contact time. The equilibrium time for 2-CP and 4-CP is 90 and 75, respectively. The removal efficiency of 4-CP is more than 2-CP. An increase in initial concentration of both compounds can lead to decrease the removal efficiency of them. The optimum pH to remove the both compound is 5. The equilibrium data is best fitted on Langmuir isotherm and the adsorption kinetic model follows pseudo-second model.Conclusion: The results indicated that Azolla is an effective adsorbent for 2-CP and 4-CP removal from water and wastewater.

Background and purpose: Sample size and its determination is one of the most important problems in health researches. Calculating sample size for prevalence studies is one of the common questions of sample size topics. Minimum sample size with least complexity is desirable in order to achieve the basic goal of these studies. This study aims to compare two formulas of sample size calculation for prevalence researches and finally, to use the simplest formula to get the most appropriate sample size.Materials and Methods: Sample size for proportions: 0.9, 0.95, 0.99, 0.999 candidates of p close to 1 proportions; 10-5, 10-4, 10-3, 10-2, 0.05, 0.1 candidates of p close to 0, and proportions 0.3, 0.4, 0.5, 0.6, 0.7 candidates of p close to 0.5 were calculated. For comparing n1, n2, j=n1/n2, it was computed by R package (2.10.1).Results: Computed sample size by (f2) is lightly greater than sample size computed by (f1) and maximum value of j index for comparing the two formulas equals 1.Conclusion: Results show that the calculated sample size by (f1) is similar to what was obtained by (f2), though, according to its interpretation and easy computation, it is suggested for all values of p.

The average attitude score of was 82.5. Regarding behavior, 13.1 percent do regular self-examination, and 15.2 percent do regular clinical examination. 16.7 percent of women have one experience of doing mammography. In the present study, there was a significant relation among knowledge, attitude and behavior.Conclusion: Since the knowledge of women was at average level and the behavior of using the screening methods was weak, planning to enable and motivate women to use the screening methods is highly emphasized.

Background and purpose: Hydatidosis is one of the most important zoonoses in the world that have public health and economic perspectives. The aim of this study was to investigate the prevalence of hydatid cysts in slaughtered animals in the industrial slaughterhouse of Khomein, Markazi province (2007-2011).Materials and Methods: In this study was investigated 28760 head of animals, including; 12860 sheep, 3840 cows and 12060 goats. Their carcasses were inspected using macroscopic method for hydatid cyst in livers and lungs. Data analysis was performed by Chi-square test and SPSS software (Version 16.0).Results: The prevalence frequency of hydatidosis in slaughtered cattle was 523 head with the most infected animals of 113 (2.94%) cow, 223 (1.73%) sheep and 187 (1.55%) goats respectively. Moreover, 1126 (3.9%) infected lungs and 1076 (3074%) infected livers were found. On the seasonal bases, the surveys showed that maximum spread of the disease was in summer.Conclusion: The prevalence of hydatid cysts of parasites is relatively high which in addition to imposing high economic losses due to the deleting of infested organs of animals and decrease in livestock products, indicates the existence of conditions for health risks for residents which requires more inclusive and comprehensive sanitary and control measures due to this parasite's life cycle and transmission.

Background and purpose: Work-related Musculoskeletal Disorder are the most prevalent workrelated disorders and are the main cause of disability among workers. Also these disorders are the main cause of absence from work and lost work hours. These lead to reduction in productivity too.Materials and Methods: This cross – sectional study was done on 100 workers of Sourak tobacco factory selected randomly. Posture analysis was evaluated by OWAS method and prevalence of musculoskeletal disorders by Nordic questionnaire. The data were analyzed using excel and Spss software version 18.Results: The mean age of workers was (43±3.97) year and work experience was 12 years. The prevalence of MSDs was 75% in the last year .the lumber region (55%), knee (45%) and shoulders (37%) were the most regions of workers complaints. OWAS posture analysis showed that the most postures are critical or need the modification intervention.Conclusion: The prevalence of musculoskeletal disorders in Sourak tobacco factory is high and the postures are inappropriate. Ergonomic interventional programs as well as workers education are recommended.

Background and purpose: There are occupational hazards to Nitrous Oxide (N2O) in operating and recovery rooms of hospitals. These hazards include, decrease mental performance and audio-visual ability, and cause reduced fertility, spontaneous abortion and neurological, renal, and liver diseases. In this survey, concentration of Nitrous Oxide in indoor air of operating and recovery rooms in hospitals of Babol University of medical sciences was determined.Materials and Methods: This descriptive study was performed in 23 operating rooms and 3 recovery rooms in 3 educational hospitals of Babol University of medical sciences. The rooms with continuous usage of N2O with 2-3 lit/min of flow for general anesthesia were studied. For sampling and detection of N2O concentration as part per million (ppm), a portable IR spectrophotometer (3015 model of Bacharach Inc.) was used. The sampling was performed in 5 different points of the operating rooms and 1 point of recovery room in 3 different hours of work time (8:30-9AM, 10:30-11AM and 12:30-1:00PM. One-way ANOVA by SPSS 18 were used to analyze of data and compare the means.Results: Mean of N2O concentration in 5 different points of the operating rooms were 318±22.6, 325.5±24.1, 299±21.8, and 301±22, 314±23.7 ppm and in recovery room were 51±15 ppm. There was no significant difference between the means of N2O concentration in different points of the operating rooms, but between the means of N2O concentration in different points of the operating rooms and recovery room were significant (p<0.05).Conclusion: Considering to the high average concentration of Nitrous Oxide in different operating and recovery rooms with maximum contamination levels of N2O, this situation puts at risk the health personnel. Therefore, further research and application protection utilizations are recommended.
