A change in patient condition is a dynamic process which can go unrecognized and result in a failure to rescue. Changes in patients’ vital signs can precede adverse events many hours before critical events such as cardiac arrest or emergent transfer to the Intensive Care Unit occurs. Quantitative assessment tools are used to predict risk and need for additional resources at the bedside. These tools are referred to as Early Warning Scoring Systems. The Royal College of Physicians developed a standardized tool called the National Early Warning Score (NEWS, 2012) that uses a variety of physiologic parameters to assess risk and establish a trigger threshold for summoning additional resources. Purpose: Early warning scoring tools have been found to be reliable and accurate in predicting patient decompensation. However, data from instruments are only as reliable and accurate as the caregiver who obtains and documents the parameters. The purpose of this study was to establish inter rater reliability between the RN and PCA using NEWS. Design, Sample, Setting, Procedures: This study was conducted on the clinical units of a 104 bed Long Term Acute Care Hospital (LTCH) system. These units accept patients directly from Intensive Care Units who require intense services to maintain their trajectory toward recovery. The NEWS provides a way for early detection of patient decompensation which can prevent readmission to acute care and the subsequent financial implications The convenience sample consisted of 22 RNs and 6 PCAs. Consented subjects reviewed an unfolding case study that portrayed a typical patient on the LTCH unit. Subjects were asked to circle the parameter ranges on the NEWS tool that corresponded to physiologic values in the scenario. Findings: Krippendorff’s alpha was utilized to determine the level of agreement among the raters examining the three scenarios. An alpha value of 0.94 was obtained indicating a high level of agreement among the raters. Conclusion: The NEWS can serve as a reliable adjunct to the provision of safe patient care. While it is not the sole source for determining

National Early Warning Score

Background: For critical patients in resuscitation room, the early prediction of potential risk and rapid evaluation of disease progression would help physicians with timely treatment, leading to improved outcome. In this study, it focused on the application of National Early Warning Score on predicting prognosis and conditions of patients in resuscitation room. The National Early Warning Score was compared with the Modified Early Warning Score) and the Acute Physiology and Chronic Health Evaluation II. Objectives: To assess the significance of NEWS for predicting prognosis and evaluating conditions of patients in resuscitation rooms. Methods: A total of 621 consecutive cases from resuscitation room of Xuanwu Hospital, Capital Medical University were included during June 2015 to January 2016. All cases were prospectively evaluated with Modified Early Warning Score, National Early Warning Score, and Acute Physiology and Chronic Health Evaluation II and then followed up for 28 days. For the prognosis prediction, the cases were divided into death group and survival group. The Modified Early Warning Score, National Early Warning Score, and Acute Physiology and Chronic Health Evaluation II results of the two groups were compared. In addition, receiver operating characteristic curves were plotted. The areas under the receiver operating characteristic curves were calculated for assessing and predicting intensive care unit admission and 28-day mortality. Results: For the prognosis prediction, in death group, the National Early Warning Score (9.50 ± 3.08), Modified Early Warning Score (4.87 ± 2.49), and Acute Physiology and Chronic Health Evaluation II score (23.29 ± 5.31) were significantly higher than National Early Warning Score (5.29 ± 3.13), Modified Early Warning Score (3.02 ± 1.93), and Acute Physiology and Chronic Health Evaluation II score (13.22 ± 6.39) in survival group ( p < 0.01). For the disease progression evaluation, the areas under the receiver operating characteristic curves of National Early Warning Score, Modified Early Warning Score, and Acute Physiology and Chronic Health Evaluation II were 0.760, 0.729, and 0.817 ( p < 0.05), respectively, for predicting intensive care unit admission; they were 0.827, 0.723, and 0.883, respectively, for predicting 28-day mortality. The comparison of the three systems was significant ( p < 0.05). Conclusion: The performance of National Early Warning Score for predicting intensive care unit admission and 28-day mortality was inferior than Acute Physiology and Chronic Health Evaluation II but superior than Modified Early Warning Score. It was able to rapidly predict prognosis and evaluate disease progression of critical patients in resuscitation room.

Background: Chelsea and Westminster Hospital introduced the Chelsea Early Warning Score (CEWS) in 2007 to aid the recognition of acutely unwell patients. The Royal College of Physicians subsequently recommended a National Early Warning Score (NEWS) for implementation across the NHS. The aim of this study was to evaluate local adherence to CEWS to identify potential obstacles to the consistent implementation of NEWS. Method: Emergency Department (ED) and Acute Assessment Unit (AAU) notes were retrospectively reviewed for a convenience sample of 102 patients admitted to the AAU. Outcome measures were completeness of documentation of CEWS parameters, documentation and accuracy of aggregate CEWS scores. Aggregate NEWS scores were calculated from the documented observations and the calculated CEWS and NEWS scores were compared. Results: Physiological observations were documented for all patients attending the ED and AAU. Heart rate, blood pressure, respiratory rate, oxygen saturation and conscious level were documented in over 95% of ED and AAU patients. Urine output was recorded for only 48% of ED and 69% of AAU patients. Aggregate CEWS scores were documented for 66% of ED and 84% of AAU patients. These were calculated accurately in 73% of ED and 79% of AAU patients. Calculation errors were eleven times more likely to result in under-scoring than over-scoring. NEWS scores were significantly higher than CEWS for the same observations and would have resulted in a 71% increase in patients requiring escalation of care in the ED and a 116% increase in AAU. Conclusion: Concerns highlighted with CEWS were the incomplete and inaccurate recording of aggregate scores, with underscoring resulting in the potential failure to recognise deteriorating patients. It is anticipated that NEWS will be accompanied by standardised documentation and training across the NHS which will support more complete and accurate recording of physiological data. Furthermore, NEWS appears from this study to be more sensitive than CEWS, thereby minimising the chance of missed deterioration.

The Impact

Background Intensive care unit (ICU) readmissions have been shown to increase a patient’s in-hospital mortality and length of stay (LOS). Despite this, no methods have been set in place to prevent readmissions from occurring. Objective The aim of this literature review was to evaluate the impact of ICU readmission on patient outcomes and to evaluate the effect of using a risk stratification tool, the National Early Warning Score (NEWS), on ICU readmissions. Methods A database search was performed on PubMed, Cumulative Index of Nursing and Allied Health Literature, Google Scholar, and ProQuest. In the initial search, 2028 articles were retrieved; after inclusion and exclusion criteria were applied, 12 articles were ultimately used in this literature review. Results This literature review found that patients readmitted to the ICU have an increased mortality rate and LOS at the hospital. The sample sizes in the reviewed studies ranged from 158 to 745,187 patients. Readmissions were most commonly associated with respiratory issues about 18% to 59% of the time. The NEWS has been shown to detect early clinical deterioration in a patient within 24 hours of transfer, with a 95% CI of 0.89 to 0.94 (P<.001), a sensitivity of 93.6% , and a specificity of 82.2%. Conclusions ICU readmissions are associated with worse patient outcomes, including hospital mortality and increased LOS. Without the use of an objective screening tool, the provider has been solely responsible for the decision of patient transfer. Assessment with the NEWS could be helpful in decreasing the frequency of inappropriate transfers and ultimately ICU readmission.
