Impact of an intensivist-led multidisciplinary extended rapid response team on hospital-wide cardiopulmonary arrests and mortality.

OBJECTIVE: The effectiveness of rapid response teams remains controversial. However, many studied rapid response teams were not intensivist-led, had limited involvement beyond the initial activations, and did not provide post-ICU follow-up. The objective of this study was to examine the impact of implementing an intensivist-led multidisciplinary extended rapid response team on hospital-wide cardiopulmonary arrests and mortality. DESIGN: This was a pre-post rapid response team implementation study. SETTING: : Tertiary care academic center in Saudi Arabia. PATIENTS: A total of 98,391 patients in the 2-yr pre-rapid response team and 157,804 patients in the 3-yr post-rapid response team implementation were evaluated. INTERVENTION: The rapid response team was activated by any health care provider based on pre-defined criteria and a four-member intensivist-led multidisciplinary rapid response team responded to provide the necessary management and disposition. The rapid response team function was extended to provide follow-up until clinical stabilization. In addition, the rapid response team provided a mandatory post-ICU follow-up for a minimum of 48 hrs. MEASUREMENTS AND MAIN RESULTS: The primary outcomes were cardiopulmonary arrests and mortality. After rapid response team implementation, non-ICU cardiopulmonary arrests decreased from 1.4 to 0.9 per 1,000 hospital admissions (relative risk, 0.68; 95% confidence interval, 0.53-0.86; p = 0.001) and total hospital mortality decreased from 22.5 to 20.2 per 1,000 hospital admissions (relative risk, 0.90; 95% confidence interval, 0.85-0.95; p < 0.0001). For patients who required admission to the ICU, there was a significant reduction in the Acute Physiology and Chronic Health Evaluation II scores after rapid response team implementation from 29.3 ± 9.3 to 26.9 ± 8.5 (p < 0.0001), with reduction in hospital mortality from 57.4% to 48.7% (relative risk, 0.85; 95% confidence interval, 0.78-0.92; p < 0.0001). Do-not-resuscitate orders for ward referrals increased from 0.7 to 1.7 per 1,000 hospital admissions (relative risk, 2.58; 95% confidence interval, 1.95-3.42; p < 0.0001) and decreased for patients admitted to ICU from the wards from 30.5% to 26.1% (relative risk, 0.86; 95% confidence interval, 0.74-0.99; p = 0.03). Additionally, ICU readmission rate decreased from 18.6 to 14.3 per 100 ICU alive discharges (relative risk, 0.77; 95% confidence interval, 0.66-0.89; p < 0.0001) and post-ICU hospital mortality from 18.2% to 14.8% (relative risk, 0.85; 95% confidence interval, 0.72-0.99; p = 0.04). CONCLUSION: The implementation of rapid response team was effective in reducing cardiopulmonary arrests and total hospital mortality for ward patients, improving the outcomes of patients who needed ICU admission and reduced readmissions and mortality of patients who were discharged from the ICU.

The impact of introducing automated eGFR reporting on uncovering new cases of chronic kidney disease in a University Hospital in Saudi Arabia.

OBJECTIVE: To determine the impact of introducing eGFR automated reporting on uncovering new cases of Chronic Kidney Disease. METHODS: All serum creatinine (SCr) in adult patients attending outpatient clinics over a two-month period were recorded and eGFR estimated. Cases with a SCr within normal limits but were in CKD stage 3 (<60 mL/min) or higher were recorded and their numbers, percentages and mean ages calculated. Stages 1 and 2 were excluded from analysis because urinary albumin and other urinary abnormalities were not checked. RESULTS: A total of 26,422 SCr from different patients were included. The mean SCr was 92.5 ± 130.9 µmol/ and the mean eGFR was 99.8 ± 32.4 mL/min/1.73 m(2). Of all the10,601 males with normal SCr, 0.84% were in CKD stage 3 and in all the 14,695 female, 19.24% were in stage 2 in stage. Of all the 14,695 females with serum creatinine in the normal range, 200 (1.36%) were in CKD stage 3. The patients in stages 2 and 3 were significantly older. CONCLUSION: If our findings are shown to be true for the rest of Saudi Arabia, one could extrapolate that for each 100,000 serum creatinine assayed for males, 840 new cases will be uncovered in CKD stage 3. The corresponding number for females would be 1360 cases.

Impact of computerized physician order entry (CPOE) system on the outcome of critically ill adult patients: a before-after study.

BACKGROUND: Computerized physician order entry (CPOE) systems are recommended to improve patient safety and outcomes. However, their effectiveness has been questioned. Our objective was to evaluate the impact of CPOE implementation on the outcome of critically ill patients. METHODS: This was an observational before-after study carried out in a 21-bed medical and surgical intensive care unit (ICU) of a tertiary care center. It included all patients admitted to the ICU in the 24 months pre- and 12 months post-CPOE (Misys®) implementation. Data were extracted from a prospectively collected ICU database and included: demographics, Acute Physiology and Chronic Health Evaluation (APACHE) II score, admission diagnosis and comorbid conditions. Outcomes compared in different pre- and post-CPOE periods included: ICU and hospital mortality, duration of mechanical ventilation, and ICU and hospital length of stay. These outcomes were also compared in selected high risk subgroups of patients (age 12-17 years, traumatic brain injury, admission diagnosis of sepsis and admission APACHE II > 23). Multivariate analysis was used to adjust for imbalances in baseline characteristics and selected clinically relevant variables. RESULTS: There were 1638 and 898 patients admitted to the ICU in the specified pre- and post-CPOE periods, respectively (age = 52 ± 22 vs. 52 ± 21 years, p = 0.74; APACHE II = 24 ± 9 vs. 24 ± 10, p = 0.83). During these periods, there were no differences in ICU (adjusted odds ratio (aOR) 0.98, 95% confidence interval [CI] 0.7-1.3) and in hospital mortality (aOR 1.00, 95% CI 0.8-1.3). CPOE implementation was associated with similar duration of mechanical ventilation and of stay in the ICU and hospital. There was no increased mortality or stay in the high risk subgroups after CPOE implementation. CONCLUSIONS: The implementation of CPOE in an adult medical surgical ICU resulted in no improvement in patient outcomes in the immediate phase and up to 12 months after implementation.

Does repeated Ramadan fasting adversely affect kidney function in renal transplant patients?

This is a prospective cohort study in renal transplant patients who fasted or who did not fast for three consecutive Ramadans. The baseline estimated glomerular filtration rate (GFR), mean arterial pressure (MAP), and urinary protein excretion before the first Ramadan were compared to those after the third Ramadan in 35 fasters and 33 nonfasters. The effect of age, time after transplantation, presence of diabetes mellitus (DM), and proteinuria on changes in the GFR were studied. The two groups were comparable in gender, age, donor source, time posttransplantation, presence of DM, hypertension, proteinuria, serum creatinine, and MAP. Among the fasters, there was no change in estimated GFR after fasting for three Ramadans (56.4 mL/min versus 55.4 mL/min, P=0.8) even after adjusting for age, DM, baseline GFR, proteinuria, or time after transplantation. There were no significant differences between the fasters and the nonfasters in the changes in GFR, MAP, and urinary protein excretion between baseline and the third Ramadan.

What is the most appropriate formula to use in estimating glomerular filtration rate in adult Arabs without kidney disease?

BACKGROUND: In clinical practice, the glomerular filtration rate (GFR) is often estimated by the Modification of Diet in Renal Disease (MDRD) or Cockcroft-Gault (CG) formulae. No data are available, however, on the performance of these formulae in Arab individuals. METHODS: Plasma creatinine samples were obtained from 90 consecutive normal Arab kidney donors for the estimation of GFR (eGFR) using the simplified MDRD and CG formulae. The GFR was measured in these donors with chromium labelled EDTA {[51Cr] EDTA). Bias was assessed by calculating the difference between the measured GFR and the calculated GFR using each of the two formulae; precision was calculated using the r value of the regression analysis. RESULTS: The group studied consisted of 90 donors, of whom 64 were males (71%). The mean age was 30.8 years (+/- 9.8) and mean BMI was 25.7 (+/- 5.7). The measured GFR (mean 112.4 +/- 17.5) correlated better with the calculated GFR by CG formula (mean 107.7 +/- 29.7) and showed poor correlation with the GFR estimated by the MDRD (mean 89.2 +/- 13.8); bias = 4.8 and 23.3, respectively (p = 0.1 and < 0.0001, respectively). The correlation with CG formula was better in males (bias = 2, p = 0.5) and those under 30 years of age (bias = 1.0, p = 0.9). Based on our data, we calculated a correction factor to the CG formula to improve the correlation with the measured GFR in Arab individuals. By multiplying the CG formula by 1.0446, the bias was reduced from 4.8 (p = 0.1) to 0.0 (p = 0.5) with an increase in precision from 0.2 (p = 0.05) to 0.43 (p = 0.0001). Using CG formula, the frequency for values within 30% of the mean of the measured value was 75%, which improved to 80% using the revised formula. CONCLUSIONS: CG formula was found to be the most appropriate for calculation of GFR in Arab individuals. It is possible to reduce the bias and improve precision in Arab individuals with normal renal function by multiplying the result obtained by CG formula by 1.0446.

Level of health awareness of Saudi patients on renal replacement therapy.

OBJECTIVE: To assess health awareness in patients on renal replacement therapy (RRT) in Saudi Arabia. METHODS: This is a cross-sectional survey using a 22-item questionnaire in 143 randomly selected adult RRT patients [40 on hemodialysis (HD), 61 on peritoneal dialysis (PD) and 42 with renal transplant (TX)]. The study was carried out at King Abdul-Aziz Medical City, Riyadh in April 2006. The questionnaire was designed to evaluate patients' knowledge in 5 areas: 1. causes of renal failure, 2. biology of the kidneys, 3. symptoms of kidney disease, 4. therapeutic options available, 5. national kidney patients support facilities. The association between the level of awareness (the percentage of correct answers) to different demographic factors was assessed. RESULTS: Three fifths of the patients had less than secondary education. The average mark for correct responses of all patients was 45.9% with a highest (58%) for the category on biology of the kidney and lowest (36.8%) for national kidney patients support facilities. The PD group had the highest score (54.4%) followed by HD (44.3%) and finally TX (35.1%). CONCLUSION: The level of our patients; health awareness is lower than satisfactory. Level of education seems to be a contributory factor.

The impact of a multifaceted intervention including sepsis electronic alert system and sepsis response team on the outcomes of patients with sepsis and septic shock.

BACKGROUND: Compliance with the clinical practice guidelines of sepsis management has been low. The objective of our study was to describe the results of implementing a multifaceted intervention including an electronic alert (e-alert) with a sepsis response team (SRT) on the outcome of patients with sepsis and septic shock presenting to the emergency department. METHODS: This was a pre-post two-phased implementation study that consisted of a pre-intervention phase (January 01, 2011-September 24, 2012), intervention phase I (multifaceted intervention including e-alert, from September 25, 2012-March 03, 2013) and intervention phase II when SRT was added (March 04, 2013-October 30, 2013) in a 900-bed tertiary-care academic hospital. We recorded baseline characteristics and processes of care in adult patients presenting with sepsis or septic shock. The primary outcome measures were hospital mortality. Secondary outcomes were the need for mechanical ventilation and length of stay in the intensive unit and in the hospital. RESULTS: After implementing the multifaceted intervention including e-alert and SRT, cases were identified with less severe clinical and laboratory abnormalities and the processes of care improved. When adjusted to propensity score, the interventions were associated with reduction in hospital mortality [for intervention phase II compared to pre-intervention: adjusted odds ratio (aOR) 0.71, 95% CI 0.58-0.85, p = 0.003], reduction in the need for mechanical ventilation (aOR 0.45, 95% CI 0.37-0.55, p < 0.0001) and reduction in ICU LOS and hospital LOS for all patients as well as ICU LOS for survivors. CONCLUSIONS: Implementing a multifaceted intervention including sepsis e-alert with SRT was associated with earlier identification of sepsis, increase in compliance with sepsis resuscitation bundle and reduction in the need for mechanical ventilation and reduction in hospital mortality and LOS.

This paper summarizes the roundtable discussion in September 25, 2013, Riyadh, Saudi Arabia as part of the World Sepsis Day held in King Abdulaziz Medical City, Riyadh. The objectives of the roundtable discussion were to (1) review the chasm between the current management of sepsis and best practice, (2) discuss system redesign and role of the microsystem in sepsis management, (3) emphasize the multidisciplinary nature of the care of sepsis and that improvement of the care of sepsis is the responsibility of all, (4) discuss the bundle concept in sepsis management, and (5) reflect on the individual responsibility of the health care team toward sepsis with a focus on accountability and the moral agent.

Safety climate in dialysis centers in Saudi Arabia: a multicenter study.

OBJECTIVE: The aim of this study was to assess the safety climate as perceived by nurses and physicians in the dialysis units in Saudi Arabia. METHODS: This is a cross-sectional survey-based multicenter study using the Safety Climate Scale, which assesses the perception by staff of the prevailing climate of safety. We used 17 items in this survey. These could be further divided into 3 summative categories: (a) handling of errors and safety concerns (9 items), (b) leadership emphasis of safety (7 items), and (c) overall safety recommendation (1 item). The survey uses 5 Likert scale options (1, disagree strongly; 2, disagree slightly; 3, neutral; 4, agree slightly; and 5, agree strongly). RESULTS: There were 509 respondents--a response rate of 76.6% and 53.3% among nurses and physicians, respectively. The internal consistency using Cronbach α was 0.899. The overall mean (SD) of satisfaction with safety climate was higher among the nurses than the physicians (4.13 [1.1] and 4.05 [1.7], respectively; P = 0.029). The overall agreement rate was 73.8%, with more nurses than physicians agreeing that safety climate prevails the dialysis center (75.4% versus 72.1%, respectively; P = 0.047).The respondents perceived a stronger commitment to safety from their clinical area leaders than from senior leaders in the organization (76.2% and 72.4%, respectively). In addition, the physicians gave lower scores to more questions than the nurses particularly in 3 areas, namely, "leadership is driving us to be a safety-centered institution" (71.5% versus 76.5%; P = 0.037), "I am encouraged by my colleagues to report any patient safety concerns I may have" (67.4% versus 84.7%; P = 0.03), and "I know proper channels to ask questions about safety" (69.6% versus 87.2%; P = 0.002).The scores by the physicians in all the 3 summative categories were again less than the scores by the nurses, but this did not reach a statistical significance. CONCLUSIONS: The nurses had higher perceptions of a prevailing safety climate than the physicians. There was a perception of a stronger commitment to safety from their clinical area leaders than from senior leaders in the organization. Senior management needs to relay their commitments to safety more effectively especially to physicians and to open clear and easily accessible channels for communication for safety issues.

This paper summarizes the roundtable discussion from the Second International Patient Safety Conference held in April 9-11, 2013, Riyadh, Saudi Arabia. The objectives of the roundtable discussion were to: (1) review the conceptual framework for building capacity in quality and safety in critical care. (2) examine examples of leading international experiences in building capacity. (3) review the experience in Saudi Arabia in this area. (4) discuss the role of building capacity in simulation for patient safety in critical care and (5) review the experience in building capacity in an ongoing improvement project for severe sepsis and septic shock.

Incident reporting at a tertiary care hospital in Saudi Arabia.

OBJECTIVE: This study aimed to examine the rates and categories of incident reports in an academic tertiary care center in Saudi Arabia both hospital-wide and in the intensive care unit (ICU). Such information would help in redesigning systems and in planning and developing strategies with the goal of improving patient safety and quality of care. METHODS: In this descriptive study, we evaluated all incident reports submitted through the paper-based reporting system in the hospital and the ICU for the year 2008. Incident report rates were calculated as the number of incident reports per 1000 patient days. We also reviewed the major and minor categories of the generated reports. RESULTS: A total of 3041 incident reports were submitted from all hospital areas; yielding a rate of 5.8 per 1000 patient days. Sixty-two incident reports were reported from the ICU, yielding a rate of 5.8 per 1000 patient days. The most frequent type of incident reports was procedural variances (37%), followed by behavior and communication incidents (34%), hazardous and safety incidents (9.5%), and medication errors (7.4%). In the ICU, the most frequently reported type of incidents was behavior and communication incidents (30.6%), followed by procedural variances (21%) and medication errors (13%). CONCLUSIONS: Rates of incident reports at a tertiary care center in Saudi Arabia were low compared with reported international rates. The main categories of incident reports were related to procedural variances and behavior and communication incidents. These findings suggest that patient safety initiatives should focus primarily on these 2 domains. Additional prospective research is needed in this important area to further understand patient safety challenges and reporting practice and culture in the country.

Weekend and weeknight admissions have the same outcome of weekday admissions to an intensive care unit with onsite intensivist coverage.

OBJECTIVE: Several reports have indicated increased mortality for weekend and nighttime admissions to the intensive care unit. This increase has been attributed to differences in staffing levels. The impact of onsite 24-hr/7-day intensivist staffing on weekend and weeknight outcomes has not been examined before. The objective of this study was to determine whether weekend and nighttime admissions compromise patient outcome in an intensive care unit staffed by an onsite intensivist 24 hrs a day and 7 days a week. DESIGN: Cohort study. SETTING: Tertiary care medical-surgical intensive care unit staffed 24 hrs/7 days by onsite consultant intensivists with predominantly North American Critical Care Board certifications. PATIENTS: We included all emergency admissions over 4 yrs (March 1999 to February 2003) from a prospectively collected intensive care unit database. Admissions were grouped into weekday, weeknight, and weekend admissions. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Predicted mortality rates were calculated using Mortality Probability Models II0 and II24. The primary outcome was hospital mortality. Standardized mortality ratios were calculated. Secondary end points included intensive care unit mortality, duration of mechanical ventilation, intensive care unit length of stay, and the need for renal replacement therapy, tracheostomy, and pulmonary artery catheter during the intensive care unit course. A total of 2,093 admissions were included in the study, of which 31% were admitted on weekdays, 35% on weeknights, and 34% on weekends. The three groups were similar in baseline characteristics. There was no significant difference in hospital mortality rates among the three time periods (36%, 36%, and 37%, respectively, p=.90). There were also no significant differences in any of the secondary end points. CONCLUSIONS: In an intensive care unit staffed by onsite certified intensivists 24 hrs/7 days, we found no compromise in the care of patients admitted during weekends and weeknights. These findings suggest that such coverage helps in ensuring consistency of care and therefore represents a potentially improved model for intensive care unit practice.
