An early warning scoring system for detecting developing critical illness. Clin Intensive Care ; 8: QJM; 94 10 JOP; 15 6 Prevention of unplanned intensive care unit admissions and hospital mortality by early warning systems.

Dimens Crit Care Nurs. An eight year audit before and after the implementation of modified early warning score MEWS charts, of patients admitted to a tertiary referral intensive care unit after CPR. Scott RD. The direct medical costs of health care associated infections in U. Centers for Disease Control and Prevention, March Most of the hospital rooms we have been in with clinical rotations do not have a clock on the wall to use in these situations, and as stated in the article, using the wall clock leads to errors.

I am a student intern at a hospital at the moment. I am conducting a research about my hospitals MEWS consistency in use. Were there any other problems you encountered besides nurse cooperation and accuracy? Is there any other studies that have been conducted that you know of that can aid me in my research? If so please let me know. Save my name, email, and website in this browser for the next time I comment.

Improving patient safety with a modified early warning scoring system. November 10, Orange was used for higher scores 4 to 5 , indicating deterioration and the need for greater concern. Finally, red denoted a score of 6 or higher, meaning the patient was experiencing serious changes in condition that called for immediate action. For a patient with a rising score, the nurse should consider the context of the clinical situation and take appropriate nursing interventions, followed by reevaluation.

MEWS Modified Early Warning System On advice from the attending thoracic surgeon, the team agreed that a MEWS range of 2 to 3 which corresponded with the yellow MEWS score range on the chosen algorithm was an appropriate trigger range for the nurse to reassess the patient more frequently.

Pilot implementation Each employee received a MEWS reference card containing the scoring tool and algorithm for quick reference; the card fit behind the employee identification badge. Discussion In this project, the MEWS tool and algorithm proved to be an effective way to identify patients at risk for deterioration and to ensure early intervention to prevent complications.

Facilitators and barriers For MEWS screening and scoring to be effective, staff need to measure and record vital signs accurately and the nurse needs to intervene according to the calculated MEWS score. Barriers for PCTs The project leader spent time with PCTs to gain an understanding of their barriers to accurately measuring and recording respiratory rates.

If the total is 4 or more then the ward doctor is informed. The feasibility of introducing the MEWS into an acute surgical service has been demonstrated in Lanarkshire. Carberry et al. They introduced a clear call-out algorithm so that the house officer or SHO was called out to review any patient scoring four or more.

The MEWS is recorded on the observation chart every time a set of observations is made for all patients. The call-out algorithm is shown in Figure 1. We believe that the MEWS should be used routinely on all in-patients. This approach should remove the element of subjectivity in selecting patients and for the first time has allowed us to calculate the sensitivity and specificity of the MEWS for its purpose. A total of consecutive emergency and elective patients were admitted under the colorectal team between 16 May and 23 September Children admitted to the paediatric ward, day cases, and urological emergencies admitted initially under general surgeons but which were handed on to the care of the urologists within 24 h were excluded.

Patients subject to DNAR orders were included because knowledge of their physiological state may be valuable with respect to the timing of discussion with their families. Patient age, gender, ASA, operation, presence of malignancy, and the length of stay were recorded.

Every weekday, the MEWS for each observation time-point was recorded from the observation charts. The component factors that made up the highest MEWS for the h period were recorded.

The MEWS was in use clinically on weekends. For the study, these weekend scores were collated on Mondays. In order to provide benchmarks to compare the sensitivity of the MEWS as a predictor of critical care admission, the white cell count and CRP were recorded if these had been measured as part of the patient's management. For the same reason, if any patient had the criteria of systemic inflammatory response syndrome SIRS , this was documented prospectively.

Age and daily patient count were considered as parametric data. Length of stay and ASA grade were considered as ordinal data. These were analysed for significance using the Mann-Whitney U-test.

Gender, emergency or elective status, death, diagnosis of obstruction or malignancy, and existence of bowel anastomosis categorical data were analysed using the chi-squared statistic comparing the actual values to those that would be expected if each variable was evenly distributed between the high and low MEWS groups.

Sensitivity for ITU or HDU admission was calculated by number of patients triggering system who were transferred divided by all patients transferred. Specificity was calculated by true negative divided by the total number of patients. Positive predictive value PPV was calculated by number transferred divided by the number triggering system.

Negative predictive value NPV was calculated by true negative divided by the number that did not trigger the system. The mean age of the population was The male:female ratio was Elective patients were less likely to trigger the system than emergency patients. The group of patients that triggered the MEWS were older, more likely to have a diagnosis of malignancy or bowel obstruction, and to have a bowel anastomosis see Table 2.

This group had a higher mortality and longer hospital stay. Clinical outcomes of interest should be measured and reported in peer-reviewed literature to disseminate the impact on clinical outcomes.
