The aim of this study was to determine the share of health research systems in this decrease alongside other influential factors. We used random effect regression models including the 'random intercept' and 'random intercept and random slope' models to analyze the panel data from 1990 to 2010. We selected the countries with U5MRs falling between the first and third quartiles in 1990. We used both the total articles (TA) and the number of child-specific articles (CSA) as a proxy of the health research system. In order to account for the impact of other factors, measles vaccination coverage (MVC) (as a proxy of health system performance), gross domestic product (GDP), human development index (HDI), and corruption perception index (CPI) (as proxies of development), were embedded in the model. Among all the models, 'the rando...

As a first step, we performed a systematic review to identify the methods used to assess the economic impact of healthcare research, and the outcomes.

Both qualitative and quantitative approaches were used. In the quantitative section, a questionnaire had prepared for this study was completed by 88 authors country wide from randomly selected papers. In the qualitative section 13 in-depth interviews and 6 focus group discussions were held with managers and policy makers, clinical and health service providers, and researchers. Twenty four percent of the authors had no interaction whatsoever with the target audience. Lack of expectation toward creating change in the target audience, researchers' incentives, low level of trust among researchers and decision makers, absence of a predefined mechanism fo...

The objective of this study is to evaluate the applicability of capture-recapture (CRC) as an analytical method to estimate MMR in countries. We used the CRC method to estimate MMR in Iran for 2004 and 2005, using two data sources: The maternal mortality surveillance system and the National Death Registry (NDR). Because the data registry contains errors, we defined three levels of matching criteria to enable matching of cases between the two systems. Increasing the matching level makes the matching criteria less conservative. Because NDR data were missing or incomplete for some provinces, we calculated estimates for two conditions: With and without missing/incomplete data. According to the CRC method, MMR in 2004 and 2005 were 33 and 25 in the best-case scenarios respectively and 86 and 59 in the worst-case scenar...

Cancer cases referred to two main cancer centers in the country (the Shiraz cancer center and the Tehran cancer center) during last 30 years and published by the two centers were utilized. Morbidity odds ratios (MOR) were used to study trend in the occurrence of each cancer site in each center. For this purpose the cancers of interest were considered as cases; childhood cancers as controls; and calendar year as exposure. A regression line was fitted to morbidity odds ratios over years and the slope of the regression line was considered to indicate the overall trend. MORs and 95% CIs comparing the last five and first five years were computed to measure the magnitude of the change over time. The overall trend for esophageal cancer was decrease (slopes = -0.02 for Shiraz and -0.03 for Tehran); for stomach was increase (slopes = 0.04...

This study aimed to determine risk factors for breast cancer in the north of Iran. Method: A matched case-control study was conducted in Mazandaran province of Iran in 2004 of 250 biopsy proven cases of breast cancer and 500 neighbor controls that were matched by age within a 3

The objective of this study is to examine the relation of MM to socioeconomic factors and its inequality in Iran's provinces at an ecologic level. The overall MM from each province was considered for 3 years from 2004 to 2006. The five independent variables whose relations were studied included the literacy rate among men and women in each province, mean annual household income per capita, Gini coefficients in each province, and Human Development Index (HDI). The correlation of Maternal Mortality Ratio (MMR) to the above five variables was evaluated through Pearson's correlation coefficient (simple and weighted for each province's population) and linear regression - by considering MMR as the dependent variable and the Gini coefficient, HDI, and difference in literacy rate among men and women as the independent variables. The mean MMR in the years 2004...

Although the EBM, to some extent, has been attended during recent years, no result has achieved thus far. The current qualitative study is to identify the barriers to establishing development system and implementation of CPGs in Iran. Twelve semi-structured, in-depth interviews were conducted with a purposive sample of health policy and decision makers, the experts of development and or adaptation of CPGs, and the experts of EBM education and development. In addition, 11 policy-makers, decision-makers, and managers of the health system participated in a focus group discussion. The analysis of the study data was undertaken by thematic framework approach. Six themes emerged in order of their frequency include practice environment, evidence-based health care system, individual professional, politician and political context, innovation (CPG) and patients. Most of the ind...
