Preventing Harm in the ICU-Building a Culture of Safety and Engaging Patients and Families.

OBJECTIVE: Preventing harm remains a persistent challenge in the ICU despite evidence-based practices known to reduce the prevalence of adverse events. This review seeks to describe the critical role of safety culture and patient and family engagement in successful quality improvement initiatives in the ICU. We review the evidence supporting the impact of safety culture and provide practical guidance for those wishing to implement initiatives aimed at improving safety culture and more effectively integrate patients and families in such efforts. DATA SOURCES: Literature review using PubMed including evaluation of key studies assessing large-scale quality improvement efforts in the ICU, impact of safety culture on patient outcomes, methodologies for quality improvement commonly used in healthcare, and patient and family engagement. Print and web-based resources from leading patient safety organizations were also searched. STUDY SELECTION: Our group completed a review of original studies, review articles, book chapters, and recommendations from leading patient safety organizations. DATA EXTRACTION: Our group determined by consensus which resources would best inform this review. DATA SYNTHESIS: A strong safety culture is associated with reduced adverse events, lower mortality rates, and lower costs. Quality improvement efforts have been shown to be more effective and sustainable when paired with a strong safety culture. Different methodologies exist for quality improvement in the ICU; a thoughtful approach to implementation that engages frontline providers and administrative leadership is essential for success. Efforts to substantively include patients and families in the processes of quality improvement work in the ICU should be expanded. CONCLUSIONS: Efforts to establish a culture of safety and meaningfully engage patients and families should form the foundation for all safety interventions in the ICU. This review describes an approach that integrates components of several proven quality improvement methodologies to enhance safety culture in the ICU and highlights opportunities to include patients and families.

Evaluation of Noninvasive Hemoglobin Monitoring in Surgical Critical Care Patients.

OBJECTIVE: To assess the clinical utility of noninvasive hemoglobin monitoring based on pulse cooximetry in the ICU setting. DESIGN AND SETTING: A total of 358 surgical patients from a large urban, academic hospital had the noninvasive hemoglobin monitoring pulse cooximeter placed at admission to the ICU. Core and stat laboratory hemoglobin measurements were taken at the discretion of the clinicians, who were blinded to noninvasive hemoglobin monitoring values. MEASUREMENT AND MAIN RESULTS: There was a poor correlation between the 2,465 time-matched noninvasive hemoglobin monitoring and laboratory hemoglobin measurements (r = 0.29). Bland-Altman analysis showed a positive bias of 1.0 g/dL and limits of agreement of -2.5 to 4.6 g/dL. Accuracy was best at laboratory values of 10.5-14.5 g/dL and least at laboratory values of 6.5-8 g/dL. At hemoglobin values that would ordinarily identify a patient as requiring a transfusion (< 8 g/dL), noninvasive hemoglobin monitoring consistently overestimated the patient's true hemoglobin. When sequential laboratory values declined below 8 g/dL (n = 102) and 7 g/dL (n = 13), the sensitivity and specificity of noninvasive hemoglobin monitoring at identifying these events were 27% and 7%, respectively. At a threshold of 8 g/dL, continuous noninvasive hemoglobin monitoring values reached the threshold before the labs in 45 of 102 instances (44%) and at 7 g/dL, noninvasive hemoglobin monitoring did so in three of 13 instances (23%). Noninvasive hemoglobin monitoring minus laboratory hemoglobin differences showed an intraclass correlation coefficient of 0.47 within individual patients. Longer length of stay and higher All Patient Refined Diagnostic-Related Groups severity of illness were associated with poor noninvasive hemoglobin monitoring accuracy. CONCLUSIONS: Although noninvasive hemoglobin monitoring technology holds promise, it is not yet an acceptable substitute for laboratory hemoglobin measurements. Noninvasive hemoglobin monitoring performs most poorly in the lower hemoglobin ranges that include commonly used transfusion trigger thresholds and is not consistent within individual patients. Further refinement of the signal acquisition and analysis algorithms and clinical reevaluation are needed.

Perceived benefit of a telemedicine consultative service in a highly staffed intensive care unit.

PURPOSE: The aim of this study was to evaluate whether a nocturnal telemedicine service improves culture, staff satisfaction, and perceptions of quality of care in a highly staffed university critical care system. METHODS: We conducted an experiment to determine the effect of telemedicine on nursing-staff satisfaction and perceptions of the quality of care in an intensive care unit (ICU). We surveyed ICU nurses using a modified version of a previously validated tool before deployment and after a 2-month experimental program of tele-ICU. Nurses in another, similar ICU within the same hospital academic medical center served as concurrent controls for the survey responses. RESULTS: Survey responses were measured using a 5-point Likert scale, and results were analyzed using paired t testing. Survey responses of the nurses in the intervention ICU (n = 27) improved significantly after implementation of the tele-ICU program in the relations and communication subscale (2.99 ± 1.13 pre vs 3.27 ± 1.27 post, P < .01), the psychological working conditions and burnout subscale (3.10 ± 1.10 pre vs 3.23 ± 1.11 post, P < .02), and the education subscale (3.52 ± 0.84 pre vs 3.76 ± 0.78 post, P < .03). In contrast, responses in the control ICU (n = 11) declined in the patient care and perceived effectiveness (3.94 ± 0.80 pre vs 3.48 ± 0.86 post, P < .01) and the education (3.95 ± 0.39 pre vs 3.50 ± 0.80 post, P < .05) subscales. CONCLUSION: Telemedicine has the potential to improve staff satisfaction and communication in highly staffed ICUs.
