Detection of deteriorating patients after Whipple surgery by a modified early warning score (MEWS)

Abstract

Background: The modified early warning score (MEWS) was set up to supply prompt recognition of clinically deteriorating patients before they undergo a severe and life-threatening event. The study aimed to describe the probable usefulness of the MEWS in identifying deteriorating post-Whipple patients in hospital wards. Methods:We performed a study to analyze the relationship between the vital parameters and postoperative severe adverse events of patients after Whipple surgery in Guangdong Provincial People's Hospital from 2000 to 2017. In the retrospective study, a total of 13,651 sets of vital parameters in 236 Whipple postoperative patients were included. Subsequently, we applied a MEWS scoring system and explored the accuracy of the MEWS in evaluating the patients' final events versus advanced mathematical models. We then put the MEWS into the ward warning system and confirmed the accuracy of the MEWS based on the results of prospective studies again. Results:We assessed the ability of the MEWS to predict postoperative complications with an accuracy rate of 90.86-91.23%, a sensitivity of 83.04-90.88%, and a specificity of 90.85-95.73%. Conclusions:The MEWS model was applied to identify post-Whipple patients at risk of complication.Once the MEWS ≥2, interventions were needed to minimize the adverse events. Our data suggest that the MEWS is comparable to the advanced mathematical models, but MEWS is more accessible to perform and more generally applicable.

Prognostic Accuracy of Early Warning Scores for Clinical Deterioration in Patients With COVID-19

“…Its updated version, the National Early Warning Score 2 (NEWS2), with a new SpO 2 scoring scale, was published by the RCP in 2017 to improve prediction for clinical deterioration in patients with a hypercapnic respiratory failure ( 13 ). Other versions of EWS such as the Modified Early Warning Score (MEWS) ( 14 , 15 ) and Hamilton Early Warning Score (HEWS) ( 16 ) have also been recently developed to improve the early recognition of hospitalized patients at risk for deterioration, with a significant degree of variation in the clinical variables and the weightings assigned.…”

The utility of MEWS for predicting the mortality in the elderly adults with COVID-19: a retrospective cohort study with comparison to other predictive clinical scores

“…Among these scoring systems, MEWS can generally be obtained within minutes after the patient is admitted, providing a rapid assessment result for clinicians and enabling timely treatment to high risk patients ( Churpek et al, 2019 ; Salottolo et al, 2017 ; Yu et al, 2019 ). Although MEWS has been found to be useful for assessment of pneumonia deterioration, ( Jo et al, 2016 ), its utility has not been examined in predicting outcome of the older adults with COVID-19.…”

Comparison of Different Scoring Systems for Prediction of Mortality and ICU Admission in Elderly CAP Population

“…As APACHE II and PSI contained acute physiology and chronic health evaluation, timely identification of high-risk patients is difficult, 13,14 whereas other scoring systems, which would be relatively easier-to-use, have more potential in early detection and assessment of high-risk patients. [15][16][17][18] Clinically, CURB-65 and qSOFA have been widely used for severity assessment of pneumonia. The CURB-65 score consists of five projects and qSOFA is similar to the CURB-65 score in variables, incorporating hypotension, altered mental status and tachypnea.…”
