Background & Aim: Physiologic signs of anxiety usually change hemodynamic variables in patients undergoing heart catheterization. This study carried out to determine the effect of Orientation Program on hemodynamic variables in patient undergoing heart catheterization.

Methods & Materials: In this experimental study, 60 patients undergoing heart catheterization were randomly assigned to either the test or control group. Data were collected using the demographic checklist and a hemodynamic variables checklist for recording hemodynamic variables. The collected data were analyzed using the Chi-square, repeated measurement, and independent t test in the SPSS.

Results: According to the results, there were significant reductions in the systolic and diastolic blood pressures, pulse rate, respiratory rate and systolic left ventricle pressure in the intervention group after the intervention (P<0.05). There were no significant statistical difference between the two groups in systolic aorta pressure (P=0.173), diastolic aorta pressure (P=0.104), and end diastolic left ventricle pressure (P=0.886).

Conclusion: Orientation program had positive effects on most of the hemodynamic variables in the intervention group. The Orientation program is recommended to be used during invasive diagnostic procedures in order to prohibit anxiety&aposs physiologic complications.

Background & Aim: Multiple structural factors preside over burn units influence nurses&apos quality of care and their activities. The complexity and multy-dimensional nature of nursing care in these units, creates many challenges. Understanding the perspectives of people&aposs involved is recommended. This study, with a theory-to-research approach, was conducted to assess the frequency of confronting intra and extra organizational factors preside over burn units, the intensity of its related pressure, and correlations among these variables from nurses&apos perspectives.

Methods & Materials: In this cross-sectional, correlational study, 98 nurses working in the Shahid Mottahari burn center were recruited by census. Data was collected using the intra and extra organizational factors instrument, provided based on the previous grounded theory study of the researchers. Intra-organizational factors questionnaire consisted of 58 Likert type statements in eight subscales and two dimensions of frequency (α=0.94) and intensity (α=0.96). Extra-organizational factors questionnaire consisted of eight Likert type statements (α=0.74). Data were analyzed using the SPSS version 14.

Results: The results revealed that the frequency of nurses&apos confrontation with factors related to environment and patients as well as its intensity were more than other factors. Moreover, the intensity of the whole factors was more than its frequency. All the extra- organizational factors were significantly correlated with all intra-organizational factors except for the "absence of employment permission" (P<0.05).

Conclusion: This study explained the importance of intra-organizational factors of a burn center in inducing stress on nurses. In addition to verification of some relationships in the previous mid-range theory, the results of this study also modified some of its aspects. Therefore it added to the existing body of knowledge about organizational factors and job stress in burn units. Moreover, it produced some evidences to use in nursing administration and service, and finally it resulted in some directions to control stress in nurses&apos job.

  Background & Aim: The &beta-Thalassemia major is a chronic disease that needs a regular blood transfusion. The blood transfusion is a complex process with high probability of human errors during the process which results in serious adverse events in patients. Nurses should deliver care based on the best available evidence or best practice. The aim of this study was to develop an evidence-based clinical guideline of blood transfusion in children with thalassemia .

  Methods & Materials: This study was conducted during 16 months from 2013 to 2014 based on three-step process of guideline adaptation including set up, adaptation and finalization. During these steps, topic and aims of the study were clearly identified. Then health questions were designed based on the PIPOH method. After conducting systematic searches, quality of the retrieved clinical guidelines was evaluated using the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument and a committee consisting of experts and policy-makers in nursing field. After external review, expert panel meetings and consensus between members, the final version of the guideline was developed . 

  Results: The criteria of clinical practice regarding stages of blood transfusion were determined based on the evidence, cultural and health conditions and were presented in twelve sections.

  Conclusion: This clinical practice guideline developed based on evidence can guide blood transfusion process in clinical practice.

Background & Aim: Increasing understanding of death anxiety among different cultures and patient populations is critical to provide quality patient care. Researchers who investigate death anxiety, are looking for a reliable and valid instrument compatible with culture in order to achieve this goal. The aim of the study was to evaluate the psychometric properties of the Templer’s Death Anxiety Scale-Extended (TDAS-E) among a sample of chemical veterans of Iran–Iraq warfare.

Methods & Materials: In this methodological study, 300 veterans completed the Persian version of the 51-item TDAS-E in 2015. The face, content and construct validity (convergent and discriminant validity) of the TDAS-E were assessed. Also, its reliability was measured using Cronbach’s alpha coefficient, construct reliability and intra correlation coefficient.

Results: Results of exploratory and confirmatory factor analyses extracted four stable distinct factors including fear of the hereafter, fear of facing death, fear of the shortness of life, fear of dying following an incident and mishap. The fitness of the four-factor model of the Templer’s death anxiety construct was approved based on standard indices (c²/df=2.832, GFI=.915, AGFI=.873, PCFI=.657, PNFI=.612, RMSEA=.078). Discriminant and convergent validity of all factors were acceptable. Also, scale reliability was confirmed using Cronbach’s alpha coefficient (0.88), construct reliability (higher than 0.70) and intra correlation coefficient (0.87).

Conclusion: The results of the current study revealed that the four-factor construct of TDAS-E had suitable validity and reliability among Iranian chemical warfare veterans. Given the proper psychometric properties, this scale can be used in future research to evaluate death anxiety in this population.
