Item Restricted Exploring Factors Influencing Nurse Attrition in Intensive Care Unit in Critical Care in Saudi Arabia: A Systematic Review(Queens University Belfast, 2025-02-10) McKenna, Niall; Brown, MichaelBackground Methodology & search strategy Result Discussion conclusion15 0Item Restricted Perceived Barriers and Facilitators by Critical Care Nurses and The Impact of Cultural Variations Between Nurses and Patients on End-Of-Life Care at Intensive Care Units(University of Cincinnati, 2024-10-18) Alali, Khairayah; Smith, Carolyn R.Background: Due to the complexity of medical conditions in the intensive care unit (ICU), mortality rates are typically high in most hospitals. End-of-life care (EOLC) begins when curative treatments are no longer beneficial, shifting the focus to comfort and quality of life for patients and families. Despite EOLC being a standard part of ICU management, healthcare professionals encounter complexities and uncertainties when transitioning from life-saving treatments to comfort-focused care. Additionally, EOLC in the ICU is influenced by the cultural backgrounds of both nurses and patients. The nursing culture in Saudi Arabia reflects a diverse workforce, with a significant reliance on expatriate nurses from various countries, leading to cultural and language differences that can influence EOLC. Objectives: To explore the perceived barriers and facilitators of critical care nurses in providing EOLC in intensive care units, how cultural variations between nurses and patients impact care, and how nurses address and meet the cultural needs of dying patients. Method: The study employed a qualitative descriptive method, utilizing semi-structured interviews that were conducted virtually through Zoom. Purposeful sampling techniques and a homogeneous sampling approach were used to recruit participants. Open-ended questions were used from an interview guide to prompt the critical care nurses to share their viewpoints and experiences. Results: The exploration of the perceived barriers and facilitators of critical care nurses during EOLC for terminally ill patients in the ICU revealed three main themes: (a) EOLC barriers, (b) EOLC facilitators, and (c) suggestions to improve the EOLC and overcome barriers. The exploration of how cultural variations between nurses and patients impact care, and how nurses address and meet the cultural needs of dying patients revealed five main themes: (a) cultural practices and traditions of patients & families, (b) cultural competence during EOLC, (c) culturally competent nursing care decisions and actions (d) challenges in providing culturally competent nursing care, and (e) suggestions to improve cultural competence. Conclusion: This study identified barriers to EOLC, including family acceptance, understanding of EOLC, unrealistic expectations, over-involvement, poor policy awareness, staffing shortages, high workloads, care continuity, and insufficient training. Nurses showed a strong commitment to respecting patients' cultural and religious practices but faced challenges in delivering culturally competent care. Recommendations include better family education, clear communication, integrating EOLC training into nursing education, addressing language barriers, implementing advance directives, and fostering a collaborative team environment with adequate resources and flexible visiting hours. These steps can enhance the quality and compassion of EOLC.31 0Item Restricted The Impact of Positive End-Expiratory Pressure on Mortality Rate among Patients with Acute Respiratory Distress Syndrome(Saudi Digital Library, 2023-08-23) Alrayes, Mashael; Hunter, JoannaBackground: High levels of Positive End-Expiratory Pressure (PEEP) have been found to potentially increase lung volume and improve oxygenation in patients with Acute Respiratory Distress Syndrome (ARDS). They also increase the risk of lung injury caused by overdistention. ARDS has a high mortality rate; however, the impact of increased PEEP on clinical outcomes in patients with ARDS is variable. Aim: The aim of this dissertation is to examine the available studies that compared the impact of high PEEP levels with that of low PEEP levels on the reduction of ARDS mortality rates. Methods: A comprehensive search of literature on Randomised Controlled Trials (RCTs) and cohort studies was conducted using four databases—MEDLINE, Embase, Cochrane Library and CINAHL (EBSCOhost) from the last 15 years to June 2023. The inclusion criteria were studies that examined the ARDS mortality rate in patients subjected to high PEEP levels (as the intervention group) and to low PEEP levels (as the control group). An automation tool was utilised, along with duplicates removal options through Endnote and Rayyan reference management tools. Results: A total of 1637 studies were identified. They were screened through the evaluation of their titles and abstracts and then, of their full text, in accordance with predetermined inclusion and exclusion criteria. Finally, seven studies were selected and included in this dissertation. Conclusion: The mortality reduction in patients with ARDS who received higher levels of PEEP did not differ significantly from that in patients with ARDS who received lower levels of PEEP.33 0
