Background & Aim: Poor sleep quality is a common problem among patients hospitalized in the CCUs. This study aimed to determine the effect of environmental factors modification strategies on quality of sleep among patients admitted to CCU.

Methods & Materials: This was a quasi-experimental study with a single-blinded design. Sixty patients admitted to the CCU of Shariati hospital were divided into two experiment and control groups. Sleep quality was measured in the first day of admission and three days later using the Pittsburgh sleep quality index in both groups. In the intervention group, we implemented a modified work environment between the two measurements. Data were analyzed using the Chi-squared and t-test in the SPSS v.18.

Results: Findings showed a significant decrease in sleep quality in the control group after hospitalization, compared with the intervention group (P<0.001). There were no statistically significant changes in the sleep quality before and after hospitalization in the intervention group (P=0.053).

Conclusion: Using environmental factors mitigation strategies can improve sleep quality of patients admitted to CCUs.

  Background & Aim: Family caregivers play major role in caring for the patients with dementia. Meanwhile, they are at risks of various diseases. Caring for a person with Alzheimer’s disease carries a significant physical, socioeconomic and psychological burden. This study described the impact of cognitive-behavioral management on burden and problems borne by family caregivers of patients with Alzheimer's disease .

  Methods & Materials: This non-randomized controlled clinical trial was conducted on 70 family caregivers of patients with Alzheimer’s disease. The participants were subjected to experimental and control groups. The Zarit Burden Interview was used to assess the burden experienced by family caregivers of the patients. Data were then analyzed using inferential and descriptive statistical parameters (mean and SD) and paired sample t-test on the difference between the scores of pre-test and post-test . 

  Results: The mean level of caregivers’ burden as measured by ZBI was 44.56± 6.77 and 42.57±5.98, in experimental and control groups before intervention respectively. Caregivers’ burden score was 39.54±5.88 and 44.86±5.87, in experimental and control groups after intervention respectively. Results showed a significant decrease in the training group’s score (P<0.001) .

  Conclusion: Given the obtained results indicating the effectiveness of cognitive- behavioral management in reduction of caregivers’ burden, the present study can be helpful in achieving an effective solution to decrease stress among family caregivers of patients who suffer from Alzheimer's disease .

Background & Aim: Error always occurs in the health system and it can lead to irreparable consequences. Therefore, error prevention must be taken into account by the health systems. Detection of factors contributing to error is a key factor for the prevention of error. Hence, the aim of this study was to explore factors contributing to nursing error in emergency department.

Methods & Materials: This study was conducted using a qualitative approach. 17 emergency nurses participated in this study. Semi-structured interview was used to collect the data. Sampling was started as the purposive sampling and continued until the saturation of data was reached. Data were analyzed using the Elo & Kyngas (2008) qualitative content analysis approach. To achieve trustworthiness, participants were selected with maximum variation in terms of age, gender, work experience, and educational background.

Results: The analysis of data led to the emergence of 500 open codes and four categories including the predisposing factors of nurse-related error, predisposing factors of organization-related error, predisposing factors of error related to the culture of emergency department and predisposing factors of patient-related error.

Conclusion: Factors contributing to nursing errors in emergency department were very wide and multifactorial. Identifying the factors contributing to error is a first step to prevent errors. For reducing nursing error, nursing managers should pay special attention to the contributing factors of error identified by this study and implement interventions to reduce and mitigate these factors.
