RESUMO
BACKGROUND: Computerized Physician Order Entry (CPOE) analgesia-sedation protocols may improve sedation practice and patients' outcomes. We aimed to evaluate the impact of the introduction of CPOE protocol. METHODS: This was a prospective, observational cohort study of adult patients receiving mechanical ventilation, requiring intravenous infusion of analgesics and/or sedatives, and expected to stay in the intensive care unit (ICU) ≥24 h. As a quality improvement project, the study had three phases: phase 1, no protocol, July 1st to September 30th, 2010; phase 2, post implementation of CPOE protocol, October 1st to December 31st, 2010; and phase 3, revised (age, kidney and liver function adjusted) CPOE protocol, August 1st to October 31st, 2011. Multivariate analyses were performed to determine the independent predictors of mortality. RESULTS: Two hundred seventy nine patients were included (no protocol = 91, CPOE protocol = 97, revised CPOE protocol = 91). Implementation of CPOE protocol was associated with increase of the average daily dose of fentanyl (3720 ± 3286 vs. 2647 ± 2212 mcg/day; p = 0.009) and decrease of hospital length of stay (40 ± 37 vs. 63 ± 85 days, p = 0.02). The revised CPOE protocol was associated with, compared to the CPOE protocol, a decrease of the average daily dose of fentanyl (2208 ± 2115 vs. 3720 ± 3286 mcg/day, p = 0.0002) and lorazepam (0 ± 0 vs. 0.06 ± 0.26 mg/day, p = 0.04), sedation-related complications during ICU stay (3.3 % vs. 29.9 %, p <0.0001), and ICU mortality (18 % vs. 39 %, p = 0.001). The impact of the revised CPOE protocol was more evident on patients aged >70 years or with severe kidney or liver impairment. Both the original CPOE protocol and the revised CPOE protocol were not independent predictors of ICU (adjusted odds ratio [aOR] = 1.85, confidence interval [CI] = 0.90-3.78; p = 0.09; aOR = 0.70, CI = 0.32-1.53, p = 0.37; respectively) or hospital mortality (aOR = 1.12, CI = 0.57-2.21, p = 0.74; aOR = 0.80, CI = 0.40-1.59, p = 0.52; respectively). CONCLUSIONS: The implementation of a CPOE analgesia-sedation protocol was not associated with improved sedation practices or patients' outcome but with unpredicted increases of an analgesic dose. However, the revised CPOE protocol (age, kidney and liver function adjusted) was associated with improved sedation practices. This study highlights the importance of carefully evaluating the impact of changes in practice to detect unanticipated outcomes.

Introduction: The objective of this study was to describe Do-Not-Resuscitate (DNR) practices in a tertiary-care intensive care unit (ICU) in Saudi Arabia, and determine the predictors and outcomes of patients who had DNR orders. Methods: This retrospective cohort study was based on a prospectively collected database for a medical-surgicalIntensive CareDepartment in a tertiary-care center in Riyadh, Saudi Arabia (1999-2017). We compared patients who had DNR orders during the ICU stay with those with "full code." The primary outcome was hospital mortality. The secondary outcomes included ICU mortality, tracheostomy, duration of mechanical ventilation, and length of stay in the ICU and hospital. Results: Among 24790 patients admitted to the ICU over the 19-year study period, 3217 (13%) had DNR orders during the ICU stay. Compared to patients with "full code," patients with DNR orders were older (median 67 years [Q1, Q3: 55, 76] versus 57 years [Q1, Q3: 33, 71], p < 0.0001), were more likely to be females (43% versus 38%, p < 0.0001), had worse premorbid functional status (WHO performance status scores 4-5: 606[18.9%] versus 1894[8.8%], p < 0.0001), higher prevalence of comorbid conditions, and higher APACHE II score (median 28 [Q1, Q3: 23, 34] versus 19 [Q1, Q3: 13, 25], p < 0.0001) and were more likely to be mechanically ventilated (83% versus 55%, p < 0.0001). Patients had DNR orders were more likely to die in the ICU (67.8% versus 8.5%, p < 0.0001) and hospital (82.4% versus 18.1%, p < 0.0001). On multivariable logistic regression analysis, the following were associated with an increased likelihood of DNR status: increasing age (odds ratio (OR) 1.01, 95% confidence interval (CI) 1.01-1.02), higher APACHE II score (OR 1.09, 95% CI 1.08-1.10), and worse WHO performance status score. Patients admitted in recent years (2012-2017 versus 2002-2005) were less likely to have DNR orders (OR 0.35, 95% CI 0.32-0.39, p < 0.0001). Patients with DNR orders had higher ICU mortality, more tracheostomies, longer duration of mechanical ventilation and length of ICU stay compared to patients with with "full code" but they had shorter length of hospital stay. Conclusion: In a tertiary-care hospital in Saudi Arabia, 13% of critically ill patients had DNR orders during ICU stay. This study identified several predictors of DNR orders, including the severity of illness and poor premorbid functional status.
RESUMO
BACKGROUND: Promoting clinical research is important considering the shortage of clinical investigators and the increasing need for large multicenter studies. Participation of clinical staff in research is crucial to achieve this goal. Our objective was to assess the research experience and interest of clinical staff working at a tertiary-care intensive care unit (ICU) and explore the perceived research barriers. METHODS: A written survey was administered to 185 multidisciplinary ICU staff at a 900-bed tertiary-care academic hospital in Riyadh. It consisted of questions/statements on previous research experience, interests and barriers. Responses were either Yes/No answers or graded according to the 5-point Likert scale. RESULTS: Most (62.8%) staff responded (age = 33.9 +/- 7.2 years, 69.6% females, 76.0% nurses, 10.4% physicians, clinical experience = 7.6 +/- 6.8 years). Fifty (40%) respondents participated in clinical research (physicians 69.2%, nurses 37.9% and respiratory therapists 25%, p = 0.052 ), 42 (33.6%) of them in the current ICU but only 11.2% presented in-person their research projects at national/international meetings. Most respondents (86.2%) believed that participation in research would enhance their career. There was no differences in research tasks clinical staff were willing to perform except for writing manuscripts with physicians (69.2%) and respiratory therapists (58.3%) more willing than nurses (29.5%), p = 0.03. Perceived research barriers were lack of time (76.8%), of financial compensation (58.4%) and of encouragement (48.8%). CONCLUSIONS: The majority of clinical staff working at a tertiary-care ICU of an academic hospital was interested in conducting research but the lack of time, financial compensation and encouragement were perceived as significant barriers.

BACKGROUND: Community-acquired pneumonia (CAP) is a leading cause of intensive care unit (ICU) morbidity and mortality. Despite extensive international epidemiological and clinical studies to improve those patients' outcomes, local statistics in Saudi Arabia are limited. The objective of this study is to describe the clinical characteristics and outcomes of patients admitted to the ICU with the diagnosis of CAP reflecting the experience of a tertiary center over an 18-year period. METHODS: A retrospective cohort study included all consecutive adult ICU patients diagnosed with CAP between 1999 and 2017. Baseline demographics, patients' risk factors, and initial admission laboratory investigations were compared between survivors and nonsurvivors. A multivariate regression model was used to predict mortality. RESULTS: During the study period, there were 3438 patients admitted to the ICU with CAP (median age 67 [Quartile 1, 3 (Q1, Q3) 51, 76] years) and 54.4% were males, of whom 1007 (29.2%) died. The survivors compared with nonsurvivors were younger (65 vs. 70 years), less likely to have chronic liver disease (2.4% vs. 10.5%), chronic renal failure (8.1% vs. 14.4%), and be immunocompromised (10.2% vs. 18.2%), and less frequently required mechanical ventilation or vasopressors (46.2% vs. 80.5% and 29.6% vs. 55.9%, respectively). Acute Physiology and Chronic Health Evaluation (APACHE) II score was significantly higher among nonsurvivors (median score 26 vs. 20) with a longer duration of mechanical ventilation and ICU stay. Using a multivariate regression model, age, APACHE II score, bilirubin level, vasopressors, and mechanical ventilation were significantly associated with increased mortality, while diabetes was associated with lower mortality. CONCLUSION: Around one-third of patients admitted to the ICU with CAP died. Mortality was significantly associated with age, APACHE II score, vasopressor use, and mechanical ventilation. A comprehensive national registry is needed to enhance epidemiological data and to guide initiatives for improving CAP patients' outcomes.
RESUMO
This prospective quasi-experimental study from the NASAM (National Approach to Standardize and Improve Mechanical Ventilation) collaborative assessed the impact of evidence-based practices including subglottic suctioning, daily assessment for spontaneous awakening trial (SAT), spontaneous breathing trial (SBT), head of bed elevation, and avoidance of neuromuscular blockers unless otherwise indicated. The study outcomes included VAE (primary) and intensive care unit (ICU) mortality. Changes in daily care process measures and outcomes were evaluated using repeated measures mixed modeling. The results were reported as incident rate ratio (IRR) for each additional month with 95% confidence interval (CI). A comprehensive program that included education on evidence-based practices for optimal care of mechanically ventilated patients with real-time benchmarking of daily care process measures to drive improvement in forty-two ICUs from 26 hospitals in Saudi Arabia (>27,000 days of observation). Compliance with subglottic suctioning, SAT and SBT increased monthly during the project by 3.5%, 2.1% and 1.9%, respectively (IRR 1.035, 95%CI 1.007-1.064, p = 0.0148; 1.021, 95% CI 1.010-1.032, p = 0.0003; and 1.019, 95%CI 1.009-1.029, p = 0.0001, respectively). The use of neuromuscular blockers decreased monthly by 2.5% (IRR 0.975, 95%CI 0.953-0.998, p = 0.0341). The compliance with head of bed elevation was high at baseline and did not change over time. Based on data for 83153 ventilator days, VAE rate was 15.2/1000 ventilator day (95%CI 12.6-18.1) at baseline and did not change during the project (IRR 1.019, 95%CI 0.985-1.053, p = 0.2812). Based on data for 8523 patients; the mortality was 30.4% (95%CI 27.4-33.6) at baseline, and decreased monthly during the project by 1.6% (IRR 0.984, 95%CI 0.973-0.996, p = 0.0067). A national quality improvement collaborative was associated with improvements in daily care processes. These changes were associated with a reduction in mortality but not VAEs. Registration The study is registered in clinicaltrials.gov (NCT03790150).

INTRODUCTION: Hyperglycemia represents an independent prognostic factor in critically ill non-diabetic patients but not in those with diabetes. In this context, there is an ongoing debate on the benefit of an intensive insulin therapy, particularly in diabetic patients. We tested the hypothesis that expression of the receptor for advanced glycation end-products (RAGE), an important signal transduction receptor that elicits long-lasting nuclear factor kappa B (NF-κB) activation, may underlie this difference. RAGE expression is regulated by multiple ligands, including high mobility group box-1 (HMGB-1), and is reflected by its released soluble form (sRAGE). METHODS: A predesigned analysis was conducted of prospectively collected samples from 76 hyperglycemic critically ill patients (33 type-2 diabetes, 43 non-diabetes) aged ≥ 18 years with blood glucose of > 6.1 mmol/L enrolled in a randomized controlled trial comparing intensive insulin therapy with conventional insulin therapy. sRAGE and its ligand HMGB-1 together with IL-6, and soluble thrombomodulin (as markers of inflammation and endothelial cell injury, respectively) were evaluated in ICU, at Days 1, 3, 5 and 7. Plasma samples from 18 healthy subjects were used as controls. RESULTS: Both diabetic and non-diabetic hyperglycemic patients showed increased plasma sRAGE, HMGB-1 and soluble thrombomodulin levels at the time of admission to ICU. Plasma IL-6 concentration was only increased in non-diabetic patients. Plasma levels of sRAGE were higher in diabetic compared with non-diabetic patients. Intensive insulin therapy resulted in a significant decrease of sRAGE and thrombomodulin at Day 7, in diabetic but not in non-diabetic patients. Circulating sRAGE levels correlated positively with IL-6 and soluble thrombomodulin levels and inversely with HMGB-1. Multivariate regression analysis demonstrated that sRAGE remains independently correlated with HMGB-1 only in diabetic patients. Neither sRAGE nor any inflammatory markers are associated with mortality. CONCLUSIONS: These findings support the hypothesis that sRAGE release, time-course and response to intensive insulin therapy differ between hyperglycemic diabetic and non-diabetic critically ill patients. Whether this difference underlies the dissimilarity in clinical outcome of hyperglycemia in these two conditions warrants further studies.

BACKGROUND: The COVID-19 pandemic has strained ICUs worldwide. To learn from our experience, we described the critical care response to the outbreak. METHODS: This is a case study of the response of the Intensive Care Department (75-bed capacity) at a tertiary-care hospital to COVID-19 pandemic, which resulted in a high number of critically ill patients. RESULTS: Between March 1 and July 31, 2020, 822 patients were admitted to the adult non-cardiac ICUs with suspected (72%)/confirmed (38%) COVID-19. At the peak of the surge, 125 critically ill patients with COVID-19 were managed on single day. To accommodate these numbers, the bed capacity of 4 ICUs was increased internally from 58 to 71 beds (+40%) by cohorting 2 patients/room in selected rooms; forty additional ICUs beds were created in 2 general wards; one cardiac ICU was converted to managed non-COVID-19 general ICU patients and one ward was used as a stepdown for COVID-19 patients. To manage respiratory failure, 53 new ICU ventilators, 90 helmets for non-invasive ventilation and 47 high-flow nasal cannula machines were added to the existing capacity. Dedicated medical teams cared for the COVID-19 patients to prevent cross-contamination. The nurse-to-patient and RT-to-patient ratio remained mostly 1:1 and 1:6, respectively. One-hundred-ten ward nurses were up-skilled to care for COVID-19 and other ICU patients using tiered staffing model. Daily executive rounds were conducted to identify patients for transfer and at least 10 beds were made available for new COVID-19 admissions/day. The consumption of PPE increased multiple fold compared with the period preceding the pandemic. Regular family visits were not allowed and families were updated daily by videoconferencing and phone calls. CONCLUSIONS: Our ICU response to the COVID-19 pandemic required almost doubling ICU bed capacity and changing multiple aspects of ICU workflow to be able to care for high numbers of affected patients.

OBJECTIVE: The purpose of this study was to examine whether sedation goals, utilizing a validated sedation assessment scale, the Riker Sedation-Agitation Scale (SAS), and a standardized sedation protocol, were achieved in Intensive Care Unit (ICU) patients. DESIGN: This is a nested prospective cohort study SETTING: The study was conducted in a tertiary care medical-surgical ICU. PATIENTS: All mechanically ventilated adult patients who were judged by their treating intensivists to require intravenous sedation for more than 24 hours, were included in the study. INTERVENTIONS: A goal-directed protocol using the SAS was initiated following an educational program to the medical and nursing staff. MEASUREMENTS AND MAIN RESULTS: The following data was collected: patients' demographics, Acute Physiology and Chronic Health Evaluation (APACHE) II score, reason for admission, and outcome. For the first five ICU days, the bedside nurse documented ordered and average achieved SAS scores, every 4 hours. We compared the targeted versus achieved SAS scores using a paired Student's t-test. One hundred and five (105) patients were included in the study with mean age (+/-SD) of 47 (+/-23) and APACHE II (+/-SD) of 21 (+/-9). Achieved sedation scores were consistently lower than the requested goals during daytime and nighttime shifts throughout the study period. This did not change even after 3 months of implementing the protocol. CONCLUSION: Achieved levels of SAS score were consistently lower than what was requested by physicians despite an educational program and the use of a standardized protocol. Differences between targeted and achieved SAS scores persisted throughout the whole study period even three months after protocol implementation. These data suggest the need for alternative, more sensitive and precise approaches, to titrate sedation to targeted levels.

INTRODUCTION: Sedation protocols have demonstrated effectiveness in improving ICU sedation practices. However, the importance of multifaceted multidisciplinary approach on the success of such protocols has not been fully examined. METHODS: The study was conducted in a tertiary care medical-surgical ICU as a prospective, 4-pronged, observational study describing a quality improvement initiative that employs 2 types of controlled comparisons: a "before and after" comparison related to intense education of ICU clinicians and nurses about sedation and analgesia in the ICU, and a comparison of protocolized versus non-protocolized care. Patients were assigned alternatively to receive sedation by a goal-directed protocol using the Riker Sedation-Agitation Scale (SAS) or by standard practice. A multifaceted multidisciplinary educational program was initiated including the use of point of use reminders, directed educational efforts, and opinion leaders. This included several lectures and in-services and the routine availability of at least one member of this group to answer questions. We included all consecutive patients receiving mechanical ventilation, who were judged by their treating team to require intravenous sedation. MEASUREMENTS AND MAIN RESULTS: The following data was collected: demographics, Acute Physiology and Chronic Health Evaluation (APACHE) II score and Simplified Acute Physiology score (SAPS) II, daily doses of analgesics and sedatives, duration of mechanical ventilation, ICU length of stay (LOS) and ventilator associated pneumonia (VAP) incidence. To examine the effect of the multifaceted multidisciplinary approach, we compared the first 3 months to the second 3 months in the following 4 groups: G1 no protocol group in the first 3 months, G2 protocol group in first 3 months, G3 no protocol group in the second 3 months, G4 protocol group in the second 3 months. After ICU day 3, SAS in the groups G2, G3 and G4 became higher than in G1 reflecting "lighter" levels of sedation. There were significant reductions in the use of analgesics and sedatives in the protocol group after 3 months. This was associated with a reduction in VAP rate and trends towards shorter mechanical ventilation duration and hospital length of stay (LOS). CONCLUSIONS: The implementation of a multifaceted multidisciplinary approach including the use of point of use reminders, directed educational efforts, and opinion leaders along with sedation protocol led to significant changes in sedation practices and improvement in patients' outcomes. Such approach appears to be critical for the success of ICU sedation protocol.

A multidisciplinary team was formed to improve hand hygiene (HH) practices in a tertiary-care ICU. At baseline, an audit revealed that the overall HH compliance was 64% and was significantly lower at night than during the day shift. After implementing a stepwise multifaceted approach that included education, workplace reminders, active feedback and later universal contact precautions, the HH compliance improved significantly to >80%, and the improvement was sustained over several months. This improvement was noted during the day and night and affected different healthcare workers as well as visitors.
