RESUMO
Cardiac syndrome X is a relatively common disorder, and still not much is known about the causative factors or its pathophysiology, which makes it difficult to cure. Due to its chronic nature and debilitating symptoms, many patients have significantly reduced quality of life [QOL].The purpose of this study was to assess the impact of phase III cardiac rehabilitation [CR] and relaxation on the QOL of patients. This research is a randomized clinical trial study. Forty eligible and consenting women [age 30-65 years] were randomly assigned to four groups. In the first group [n = 11], progressive muscle relaxation [PMR]; in the second group [n = 11], phase III CR; and in the third group [n = 11], PMR along with phase III CR were performed for 8 weeks at home. The fourth group [n = 7] was used as the control group. Short form of QOL questionnaire [SF 36] was used for data gathering.Data analysis was performed using X[2], Kruskal-Wallis, and rank sum difference tests. After phase III CR, relaxation, and combination of CR and relaxation, patients demonstrated improved QOL [P < 0.001]. The results of post test multiple comparisons showed that there were statistically significant differences between control and all intervention groups [P < 0.05]. There was also statistically significant difference between relaxation and combination of phase III CR and relaxation groups [P < 0.5]. An 8 week phase III CR program together with relaxation improved QOL of patients with cardiac syndrome X. We suggest phase III CR program together with relaxation as an effective treatment in these patients.
RESUMO
Picture Archiving and Communication System [PACS] provides the possibility of electronic transfer and storage of medical images in different units of treatment and educational centers. The aim of this study was to determine the problems and obstacles related to implementation of PACS in Urmia Imam Khomeini hospital. In this descriptive study, 88 physicians, nurses, radiographers, health information managers and executive managers in Urmia Imam Khomeini hospital were assessed. The sample size was accordance to the size of population; so, the census method was used for sampling. Data collection was performed by two questionnaires. The validity and reliability of the questionnaires were confirmed by content validity and test-retest method respectively. The four areas composed of human resources, management, organizational and technological factors which evaluated with those questionnaires. The data analysis was conducted based on the descriptive analysis. Results in four areas showed that the knowledge of employees and managers with the concept of PACS was 43.1% and 83.3% respectively. The findings also indicated that the interest of employees and managers to implementing such a system were 80% and 66.7% respectively. Based on the opinions of both managers and employees, it was found that the lack of awareness of hospital executive managers was the most important obstacle in the implementation of the PACS. Considering the progress in the medical informatics domain and applications of health information systems, it is necessary that the executive managers apply such systems in hospitals
