Clinical education is one of the most important and crucial parts of nursing education. Successful clinical education needs to adopt effective and new approaches to be more helpful. The aim of this study was to investigate the effects of competency-based mastery learning on practical learning of nursing students.

In a quasi-experimental study using pre-test and post-test with two group design, 28 nursing students were selected through census sampling method and placed randomly in two control and two experiment groups, each group containing six to seven people. After taking the cognitive skills pre-tests, the control group received traditional education and experiment group went under clinical education using competency-based mastery learning program for 12 days. As the final step, the post-test cognitive skills were held and behaviors skill checklist were observed. The data were analyzed by SPSS software using Wilcoxon and Mann Whitney tests and Pearson correlation coefficient.

The findings showed that the participation of the competency-based mastery learning was effective in promoting their knowledge and skills. The mean scores differed significantly before and after participating in competency-based mastery learning. There also was a significant difference before and after clinical competency nurse training in traditional education group and competency-based mastery learning group.

Competency-based mastery learning promises high level of learning for students, it seems that competency-based mastery learning was structured to maximize opportunities for learning and professional development and clinical competency.

Hospitals have a key role in providing health services as the main element of health system and have a wide impact on health system performance. They require ongoing and permanent monitoring and evaluation. This study was conducted in order to investigate the relationship between performance indicators and evaluation grade of hospitals affiliated to Urmia University of Medical Sciences.

This descriptive and cross-sectional study was done in 2010. The study population was all hospitals affiliated to Urmia University of Medical Sciences. To achieve accurate and reliable information, the required data were extracted from the statistical yearbook of Urmia University of Medical Sciences and Deputy of Health Services. The data were analyzed by statistical software SPSS and Spearman correlation coefficient.

The overall, mean of hospital bed occupancy rate, average length of stay, bed turnover rate, bed turnover interval and mortality rate were 66.12%, 2.92 days, 87.82 times a year, 2.02 days and 10.12 per thousand, respectively. Spearman correlation coefficient showed a significant relationship between evaluation score of hospitals and bed occupancy rate indicators and mortality rates (p <0.001). But the relationship between the evaluation score of hospital and average length of stay, bed turnover rate and bed turnover interval was not significant.

The absence of significant relationship between current evaluation score of the studied hospitals shows that revision and correction of the current criteria for evaluation of hospitals is needed. It is recommended to focus on performance indicators that demonstrate use of resources and facilities in hospitals.

Sleep is a physiological and reversible phenomenon. One of its primary functions is to help organisms conserve their energy resources and it has powerful effects on daytime performance, thinking, and mood. Sleep disturbances are one of the major psychological disorders. Almost 30% of the world population suffers from sleep disorders. Since there is a relationship between quality of sleep and educational progress, this descriptive study was carried out to assess nursing student's quality of sleep.

In this descriptive-analytic study, 160 nursing students that resided in Urmia dormitories of Urmia University of Medical Sciences participated in the study. Data were gathered through convenience sampling and the Pittsburgh Sleep Quality Index (PSQI) was used. The data were analyzed using SPSS software and descriptive and inferential statistical tests.

Sleep disorder prevalence in nursing students was 43.1%. The result indicated that 9.2% of boys and 9.5% of girls used hypnotics. There was a significant relationship between hypnotics use and quality of sleep (p = 0.001), so 93.3% of hypnotic drug users had low sleep quality. There was no meaningful difference about sleep disorder between boys & girl (p = 0.6). Statistical assessments indicated that there was a meaningful relation between quality of sleep and total time of night sleep (p = 0.001).

Based on this study, the prevalence of nursing students sleep disorder is high compared with the society. Regarding the advantages of good sleep and importance of resting, it is necessary to reduce causes of sleep problems, including physical, medical, mental, and environmental ones.
