BACKGROUND: There is a large body of literature examining income in relation to health expenditures. The share of expenditures in health sector from GDP in developed countries is often larger than in non-developed countries, suggesting that as the level of economic growth increases, health spending increase, too. OBJECTIVES: This paper estimates long-run relationships between health expenditures and GDP based on panel data of a sample of 12 countries of the Organization of the Petroleum Exporting Countries (OPEC), using data for the period 1995-2012. PATIENTS & METHODS: We use panel data unit root tests, cointegration analysis and ECM model to find long-run and short-run relation. This study examines whether health is a luxury or a necessity for OPEC countries within a unit root and cointegration framework. RESULTS: Panel data analysis indicates that health expenditures and GDP are co-integrated and have Engle and Granger causality. In addition, in oil countries that have oil export income, the share of government expenditures in the health sector is often greater than in private health expenditures similar developed countries. CONCLUSIONS: The findings verify that health care is not a luxury good and income has a robust relationship to health expenditures in OPEC countries.

Backgrounds and Aims: Using Geographical Information System (GIS) can decreases the burden of road traffic injuries effectively by identification of hot spot to modification in hazardous areas. The aim of the study was determining geographical distribution of human risk factors associated with road traffic injuries by using Geographical Information System (GIS) in Iran. Materials and Methods: The national database of road traffic injuries registered by the Iranian traffic Police (Rahvar NAJA) was used. The human risk factors were investigated by recognition of the hazardous points and geographical distribution of associated risk factors. The Hot Spot Analysis and Map clustering approaches were employed to meet the objectives. Results: The mean age of injured subjects was 34 years and the most affected age group was 20-39 years. Death and injury occurrence within out of cities ways were 0.3 % and 28% respectively. Geographical distribution of risk factors also showed that roads of Northern provinces i.e. (Gilaan and Mazandaran) were the hazardous rising as well as Qazvin to Rasht and Qom to Tehran roads. Sistan and Balochestan Provinces and Tehran had the highest (4.8%) and the lowest (0.1%) rates of road traffic injuries leading to death in the country. Conclusions: Northern provinces and its leading axes by hazardous rising and Sistan and Balochestan province with fatal injuries need to identify the cause of injuries' and, if necessary, more tighten regulations and more controls by the traffic police must be applied.

BACKGROUND: Heart transplantation is an established treatment for end-stage heart failure patients, but its cost-effectiveness is under question. OBJECTIVE: This study aimed to assess the cost of heart transplantation in Iran as a developing country in Asia to contribute to future planning in the region. METHODS: This study was conducted in two phases. First, in a retrospective multicenter study, hospital data of heart transplant and hospitalization of three active heart transplant centers in Tehran, Iran, were reviewed from April 2013 to May 2015. Then pre-transplantation, transplantation, and one-year posttransplant costs were calculated according to the ABC (activity-based costing) method in 2016. RESULTS: Data were obtained for 120 patients, among which 95 (79.17%) were males with a mean (SD) age of 35.31±13.41 years. Mean (SD) hospital and ICU length of stay were 17.85±14.91 and 9.74±8.94 days, respectively. A significant correlation existed between the mean of hospital and ICU length of stay (P<0.001, r: 0.754). The mean heart transplant and hospitalization cost was 3445.47±1243.29 USD from 2013 to 2015. Using the activity-based costing method, the cost of pre-transplantation, transplantation, and one-year -post-transplantation were extracted 6.5%, 73.5%, and 20%, respectively, with a total cost of 26232 USD. CONCLUSION: Compared to other countries, the cost of heart transplantation in Iran is very low. Numerous reasons lead to this difference. Firstly, a heart transplantation surgery is performed in university-based hospitals and is supported by the government. On the other hand, a significant difference exists between personnel costs in Iran compared to other countries.
