Nurses’ worry or concern and early recognition of deteriorating patients on general wards in acute care hospitals: a systematic review

INTRODUCTION:Nurses often recognize deterioration in patients through intuition rather than through routine measurement of vital signs. Adding the 'worry or concern' sign to the Rapid Response System provides opportunities for nurses to act upon their intuitive feelings. Identifying what triggers nurses to be worried or concerned might help to put intuition into words, and potentially empower nurses to act upon their intuitive feelings and obtain medical assistance in an early stage of deterioration. The aim of this systematic review is to identify the signs and symptoms that trigger nurses' worry or concern about a patient's condition.METHODS:We searched the databases PubMed, CINAHL, Psychinfo and Cochrane Library (Clinical Trials) using synonyms related to the three concepts: 'nurses', 'worry/concern' and 'deterioration'. We included studies concerning adult patients on general wards in acute care hospitals. The search was performed from the start of the databases until 14 February 2014.RESULTS:The search resulted in 4,006 records, and 18 studies (five quantitative, nine qualitative and four mixed-methods designs) were included in the review. A total of 37 signs and symptoms reflecting the nature of the criterion worry or concern emerged from the data and were summarized in 10 general indicators. The results showed that worry or concern can be present with or without change in vital signs.CONCLUSIONS:The signs and symptoms we found in the literature reflect the nature of nurses' worry or concern, and nurses may incorporate these signs in their assessment of the patient and their decision to call for assistance. The fact that it is present before changes in vital signs suggests potential for improving care in an early stage of deterioration

Surgical ward nurses� responses to worry: An observational descriptive study

Background: Rapid response systems aim to improve early recognition and treatment of deteriorating general ward patients. Sole reliance on deviating vital signs to escalate care in rapid response systems disregards nurses� judgments about a patient's condition based on worry and other indicators of deterioration. To make worry explicit, the Dutch-Early-Nurse-Worry-Indicator-Score was developed, summarising non-quantifiable signs of deterioration in the nine indicators: breathing, circulation, temperature, mentation, agitation, pain, unexpected trajectory, patient indicates not feeling well and nurses� subjective observations. Nurses� worry can be present even when vital signs are largely unchanged, enabling treatment to commence at an early stage. On the other hand, reliance on nurses� worry might lead to unnecessary calls for medical assistance or an overuse of rapid response teams. Objectives: Explore the occurrence of nurses� worry in real time, determine whether acting on worry leads to unnecessary action and determine the indicators present at different levels of deterioration. Design: A prospective cohort study. Setting: Three surgical wards in a tertiary, university affiliated teaching hospital. Participants: All nurses participated and adult, surgical, native speaking patients were included in the study. Methods: A descriptive analysis is performed on one year of data on surgical ward nurses� experience of worry and its underlying indicators in addition to routinely measured vital signs. Results: Out of a total of 46,571 measurements, vital signs were normal 18,727 times, with worry expressed 605 times (3%), resulting in 62 calls (10.2%) to the attending physician. More than half of these calls resulted in necessary interventions. Calls for assistance and subsequent intervention after worry was expressed increase in parallel with early warning scores. The breathing indicator showed the highest increase in frequency with increasing deviation in vital signs. Conclusion: This study suggests that worry has potential as an early indicator of deterioration, alerting nurses and encouraging them to start timely interventions. Overuse of medical assistance could not be determined, The Dutch-Early-Nurse-Worry-Indicator-Score objectifies worry when vital signs do not support its presence and systematic assessment of these indicators is recommended.</p

Capturing early signs of deterioration: the Dutch-Early-Nurse-Worry-Indicator-Score (DENWIS) and its value in the Rapid Response System

Item does not contain fulltextAIMS AND OBJECTIVES: To determine the predictive value of individual and combined dutch-early-nurse-worry-indicator-score indicators at various Early Warning Score levels, differentiating between Early Warning Scores reaching the trigger threshold to call a rapid response team and Early Warning Score levels not reaching this point. BACKGROUND: Dutch-early-nurse-worry-indicator-score comprises nine indicators underlying nurses' 'worry' about a patient's condition. All indicators independently show significant association with unplanned intensive care/high dependency unit admission or unexpected mortality. Prediction of this outcome improved by adding the dutch-early-nurse-worry-indicator-score indicators to an Early Warning Score based on vital signs. DESIGN: An observational cohort study was conducted on three surgical wards in a tertiary university-affiliated teaching hospital. METHODS: Included were surgical, native-speaking, adult patients. Nurses scored presence of 'worry' and/or dutch-early-nurse-worry-indicator-score indicators every shift or when worried. Vital signs were measured according to the prevailing protocol. Unplanned intensive care/high dependency unit admission or unexpected mortality was the composite endpoint. Percentages of 'worry' and dutch-early-nurse-worry-indicator-score indicators were calculated at various Early Warning Score levels in control and event groups. Entering all dutch-early-nurse-worry-indicator-score indicators in a multiple logistic regression analysis, we calculated a weighted score and calculated sensitivity, specificity, positive predicted value and negative predicted value for each possible total score. RESULTS: In 3522 patients, 102 (2.9%) had an unplanned intensive care/high dependency unit admissions (n = 97) or unexpected mortality (n = 5). Patients with such events and only slightly changed vital signs had significantly higher percentages of 'worry' and dutch-early-nurse-worry-indicator-score indicators expressed than patients in the control group. Increasing number of dutch-early-nurse-worry-indicator-score indicators showed higher positive predictive values. CONCLUSIONS: Dutch-early-nurse-worry-indicator-score indicators alert in an early stage of deterioration, before reaching the trigger threshold to call a rapid response team and can improve interdisciplinary communication on surgical wards during regular rounds, and when calling for assistance. RELEVANCE TO CLINICAL PRACTICE: Dutch-early-nurse-worry-indicator-score structures communication and recording of signs known to be associated with a decline in a patient's condition and can empower nurses to call assistance on the 'worry' criterion in an early stage of deterioration

Nurses’ ‘worry’ as predictor of deteriorating surgical ward patients; a prospective cohort study of the Dutch-Early-Nurse-Worry-Indicator-Score

Background: Nurses’ ‘worry’ is used as a calling criterion in many Rapid Response Systems, however it is valued inconsistently. Furthermore, barriers to call the Rapid Response Team can cause delay in escalating care. The literature identifies nine indicators which trigger nurses to worry about a patient's condition.Objectives: The objective of this study is to determine the significance of nurses’ ‘worry’ and/or indicators underlying ‘worry’ to predict unplanned Intensive-Care/High-Dependency-Unit admission or unexpected mortality among surgical ward patients.Design: a prospective cohort study.Setting: a 500-bed tertiary University affiliated teaching hospital.Participants: Adult, native speaking surgical patients, admitted to three surgical wards (traumatology, vascular- and abdominal/oncological surgery). We excluded patients with a non-ICU policy or with no curative treatment. Mentally incapacitated patients were also excludedMethods: We developed a new clinical assessment tool, the Dutch-Early-Nurse-Worry-Indicator-Score (DENWIS) based on signs underlying ‘worry’. Nurses systematically scored their ‘worry’ and the DENWIS once per shift or at any moment of ‘worry’. DENWIS measurements were linked to routinely measured vital signs. The composite endpoint was unplanned Intensive-Care/High-Dependency-Unit admission or unexpected mortality. The DENWIS-indicators were included in a univariate and multivariate logistic regression analysis, subsequently inserting ‘worry’ and the Early Warning Score into the model. We calculated the area under the receiver-operating characteristics curve.Results: In 3,522 patients there were 102 (2.9%) patients with unplanned Intensive Care Unit/High Dependency Unit-admissions or unexpected mortality. ‘Worry’ (0.81) and the DENWIS-model (0.85) had a lower area under the receiver-operating characteristics curve than the Early Warning Score (0.86). Adding ‘worry’ and the Early Warning Score to the DENWIS-model resulted in higher areas under the receiver operating characteristics curves (0.87 and 0.91, respectively) compared with the Early Warning Score only based on vital signs.Conclusions: In this single-center study we showed that adding the Early Warning Score based on vital signs to the DENWIS-indicators improves prediction of unplanned Intensive-Care/High-Dependency-Unit admission or unexpected mortality
