  Introduction: Pre-hospital emergency medical services may have an effective role in the survival rate and prevention of serious injuries to patients and victims. On the other hand, increased length of stay can lead to an increase in hospital and patient costs while prolonging the recovery and rehabilitation time. This study aimed to investigate the relationship between pre-hospital care and hospital length stay in patients with acute myocardial infarction in Hazrate Rasool Hospital.

  Methods: The population of this retrospective analytical cohort study constituted the patients diagnosed with Acute Myocardial Infarction hospitalized at Hazrate Rasool Hospital in Tehran in 2009. These patients were diagnosed during the first six month of 2009 and were ultimately discharged alive. The sample was the same as the study population. Data analysis was done by means of SPSS version 16, non-parametric Mann-Whitney, and Kruskal-Wallis tests.

  Results: The findings showed that 88% of the patients were transferred to the hospital with ambulance and had already received pre-hospital services. The average length of stay in the hospital was found to be 17.6 days (SD = 4.05). There were no significant differences in length of stay for the two groups of patients those taken to hospital by ambulance and those who were not. However, a significant difference was observed between patients with various age groups. Moreover, the length of stay in patients with different insurance coverage was statistically significant. (P ≤0.05)

  Conclusion : According to the findings, although the means of transportation of the patients as well

  as pre-hospital services seem to have no impact on the length of stay in hospital, they may, however, affect other consequences such as improvement in overall health of the patient, reduction of injuries, pain, etc. which may not lead to a reduction in hospital stay. It seems that in studies examining factors affecting length of stay in hospitals, researchers should have systemic and holistic views on these factors in order to obtain a realistic contribution of each factor in increasing or decreasing the length of stay.

Introduction: Unmet needs are defined as the difference between services judged necessary to deal appropriately with health problems and services actually received. Unmet needs are considered as simple tools in monitoring the accessibility and the extent of inequity in access and use of health care.
Methods: This is a cross-section health survey. The sample consists of 792 households living in Tehran. Data were collected by the WHO (households) questionnaire in 2012, and were analyzed using Logistic Model and STATA12 software.
Results: The outcomes show that economical problems, lack of time, self-treatment, long distance to reach health facilities, deprivation of insurance coverage, and lack of adequate information about the locations of health care centres are all factors affecting patients’ willingness to refer to these centres. The socio-economic factors which can enhance the probability of fulfilment of health care needs were found to be settlement ownership and poverty reduction
 Conclusion: Unmet needs can cause detrimental effects, such as worsening health situation and quality of life, increasing the risk of mortality and causing mental and psychosomatic disorders therefore, policy makers should give high priority to eliminating socio-economic barriers, as lack of insurance coverage, as well as reducing the costs and economic inequalities, and payment systems reform. Key words: Equity in health, Health care accessibility, Unmet needs, Tehran households, Logistic Model

Introduction: In both developed and developing countries, in urban and rural areas, communities are experiencing an epidemic of non-communicable diseases. Empowering people to deal effectively with this epidemic and its risk factors is essential. Therefore, in order to determine the educational needs, this study examined the level of attitude, knowledge, and practice of clients in rural health centers in relation to some risk factors for cardiovascular disease.
Methods: A cross-sectional descriptive-analytic study was conducted on 245 clients, aged 18 to 60, in rural health centers of South Khorasan province in 2017. Data were collected over a period of four weeks and analyzed with descriptive and analytical statistical methods (Pearson correlation coefficient and t-test), at the significance level of 0.05, using SPSS software version18.
Results: The mean age of the subjects was 38.5 years. The mean score of knowledge and practice of individuals in relation to cardiovascular risk factors was favorable, but the mean score of attitude was low. The results of Pearson correlation test showed that there was a significant relationship between the mean score of knowledge, attitude, and practice of individuals. The strongest relationship was between knowledge and attitude(r=0/46). According to the independent t-test, there was no significant relationship between the history of hypertension and knowledge (p = 0.7), attitude (p = 0.5) and performance (p = 0.6).
Conclusion: Although, for the success of people's empowerment policy, it is necessary to pay attention to all three dimensions of attitude, awareness, and performance, the findings of this study showed a low level of attitude. Due to the relationship between attitude and lifestyle choices and exposure to risk factors of cardiovascular disease, it is recommended that we adopt an appropriate educational policy to improve the attitude of individuals.
