Background: Critically ill patients require rapid care, yet they are also at risk for morbidity from the potential complications of that care. Computerized physician order entry (CPOE) is advocated as a tool to reduce medical errors, improve the efficiency of healthcare delivery, and improve outcomes. Little is known regarding the essential attributes of CPOE in the intensive care unit (ICU).
Objective: To assess the effect of CPOE on ICU patient care.
Design: Retrospective before and after cohort study.
Setting: An academic ICU.
Patients: Patients admitted to the ICU during use of the initial CPOE application and those admitted after its modification.
Interventions: Comprehensive order interface redesign improving clarity, specificity, and efficiency.
Measurements: Orders for complex ICU care were compared between the two groups. In addition, the use of higher-efficiency CPOE order paths was tracked.
Results: Patients treated with both the initial and modified CPOE system were similar for all measured characteristics. With the modified CPOE system, there were significant reductions in orders for vasoactive infusions, sedative infusions, and ventilator management. There was also a significant increase in orders executed through ICU-specific order sets after system modifications.
Limitations: This retrospective study cannot assess issues related to learner expertise and is meant to only suggest the importance of developing CPOE systems that are appropriate for specialty care environments.
Conclusion: Appropriate CPOE applications can improve the efficiency of care for critically ill patients. The workflow requirements of individual units must be analyzed before technologies like CPOE can be properly developed and implemented.

Background: Intensive care units (ICUs) are high-stress environments, particularly for nurses, who face numerous stressors that can negatively impact their well-being. This study aimed to examine stress levels and stressors among ICU nurses, investigate their stress coping strategies, and explore the primary stressors in this demanding work environment.
Materials And Methods: Employing a cross-sectional design, this study assessed the stress levels of ICU nurses by using the Perceived Stress Scale and their coping strategies through the Brief-COPE scale, from March 15, 2021, to April 14, 2021.

Anterior cord syndrome is a rare yet critical neurological condition that poses significant challenges in clinical management. We present the case of a 71-year-old male with a medical history of hypertension, uncontrolled type II diabetes mellitus, hypothyroidism, and end-stage renal disease requiring dialysis who presented to the emergency department with complaints of chills, back pain, abdominal pain, and vomiting episodes. Based on the severity of the patient's illness, it was decided that inpatient admission would be best.

Background: One of the most vital forms of the affected patient safety is pressure ulcers (PUs), which can be a critical health problem that every day impacts sufferers and healthcare structures. This study aimed to explore the level of nurse's knowledge and perceived barriers regarding PUs prevention among critically ill patients.
Methods: This cross-sectional study was conducted among 100 nurses who working in the critical care units (CCUs) at tertiary teaching hospitals in Baghdad City, the study extended from April to June 2024 to assess the nurses' knowledge level using the knowledge perceived barriers on the prevention of PUs questionnaire.

Background: Sepsis-induced acute kidney injury (AKI) is difficult to prevent because most patients are diagnosed after they develop it. Standard serum and urine creatinine levels are insensitive and nonspecific for detecting kidney injury in its early stages. Glutathione S-transferase (GST) has received little attention as a biomarker in AKI.
