Objective assessment of nursing workload in an intermediate care unit: A prospective observational study.

OBJECTIVES: To systematically assess the nursing workload in an Intermediate Care Unit. DESIGN: Single-centre prospective observational study. The nursing activities within the initial 72 h of hospitalization were recorded on a prespecified chart and standardized as activities/5 min/patient/day. SETTING: This study was conducted at the Intermediate Care Unit of the Altovicentino Hospital (Italy) from September 1 to December 31, 2022. MAIN OUTCOME MEASURE: We considered working overload as an average number of nursing activities/5 min/patient/day higher than the 85th percentile and investigated independent risk factors associated with it. RESULTS: A total of 183 patients were included. During their hospital stay, the average number of nursing activities per patient was 30 per 5-minute interval per day (range: 22-40). On the first day of hospitalization, the primary activities were predominantly administrative and managerial tasks. In contrast, on the second day, activities related to therapeutic management and primary care predominated. Various scores related to the patient's condition, including comorbidity, functionality, frailty, intensity, and severity, were analyzed for their association with nursing workload using multivariate analysis. However, only the National Early Warning Score was found to be an independent risk factor for nursing workload overload (OR 1.399, 95 % CI 1.205-1.624, p < 0.001). CONCLUSION: The study results demonstrated a significant variation in nursing workload within the same department. Subsequent studies are necessary to confirm the ability of the National Early Warning Score in predicting nursing over workload. IMPLICATION FOR CLINICAL PRACTICE: This study provides a detailed analysis of nursing workload in intermediate care settings, emphasizing the need for adequate resource allocation due to the potential for rapid deterioration in patients' conditions. By correlating nursing activities with patient severity indices, such as the National Early Warning Score, the findings support more effective organizational strategies to enhance care for patients at high risk of health decline.

External validation of the TFC (triage frailty and comorbidity) tool: a prospective observational study.

Assessing patient frailty during triage evaluations has become increasingly relevant in Emergency Departments (ED). This study aimed to externally validating the Triage Frailty and Comorbidity (TFC) tool. This prospective study was conducted from June 1 to December 31, 2023. During this period, 12 triage nurses applied the TFC tool during triage evaluation of ED patients. We used receiver operating characteristic (ROC) curves and Decision Curve Analysis to assess the predictive ability of the TFC tool for a 90-day mortality (the same endpoint used during tool development) and a 30-day mortality. 1270 patients were included and 56 of them died within 90 days. The TFC tool had an AUROC of 0.894 (0.858-0.929) for 90-day mortality and 0.885 (0.834-0.938) for 30-day mortality. In Decision Curve Analysis, it yielded higher net benefits up to a threshold probability of 0.30. The externally validated TFC tool appears very effective at identifying patients with increased risk of 90-day mortality after ED attendance. It could be implemented in clinical practice and enhance the predictive ability of standard triage systems.

Assessing the utility of frailty scores in triage: a comparative study of validated scales.

Currently, there is conflicting evidence regarding the efficacy of frailty scales and their ability to enhance or support triage operations. This study aimed to assess the utility of three common frailty scales (CFS, PRISMA-7, ISAR) and determine their utility in the triage setting. This prospective observational monocentric study was conducted at Merano Hospital's Emergency Department (ED) from June 1st to December 31st, 2023. All patients attending this ED during the 80-day study period were included, and frailty scores were correlated with three outcomes: hospitalization, 30-day mortality, and severity of condition as assessed by ED physicians. Patients were categorized by age, and analyses were performed for the entire study population, patients aged 18-64, and those aged 65 or older. Univariate analysis was followed by multivariable analysis to evaluate whether frailty scores were independently associated with the outcomes. In multivariable analysis, none of the frailty scores were found to be associated with the study outcomes, except for the CFS, which was associated with an increased risk of 30-day mortality, with an odds ratio of 1.752 (95% CI 1.148-2.674; p = 0.009) in the general population and 1.708 (95% CI 1.044-2.793; p = 0.033) in the population aged ≥ 65. Presently, available frailty scores do not appear to be useful in the triage context. Future research should consider developing new systems for accurate frailty assessment to support risk prediction in the triage assessment.

Enhancing triage accuracy: The influence of nursing education on risk prediction.

AIM: This study aimed to compare the performance in risk prediction of various outcomes between specially trained triage nurses and the Manchester Triage System (MTS). DESIGN: Prospective observational study. METHODS: The study was conducted from June 1st to December 31st, 2023, at the Emergency Department of Merano Hospital. Triage nurses underwent continuous training through dedicated courses and daily audits. We compared the risk stratification performed by expert nurses with that of MTS on various outcomes such as mortality, hospitalisation, and urgency defined by the physicians. Comparisons were made using the Areas Under the Receiver Operating Characteristic curve (AUROC). RESULTS: The agreement in code classification between the MTS and the expert nurse was very low. The AUROC curve analysis showed that the expert nurse outperformed the MTS in all outcomes. The triage nurse's experience led to statistically significant better stratification in admission rates, ICU admissions, and all outcomes based on the physician's assessment. CONCLUSIONS: The continuous training of nurses enables them to achieve better risk prediction compared to standardized triage systems like MTS, emphasizing the utility and necessity of implementing continuous training pathways for these highly specialised personnel.

Is the National Early Warning Score able to identify nursing activity load? A prospective observational study.

BACKGROUND: The National Early Warning Score scale correlates well with the intensity of the patient's acute condition. It could also correlate with the nursing activity load and prove useful in defining and redistributing nursing resources based on the acuity of patients. AIM: To assess whether patients' National Early Warning Score at hospital admission correlates with objective nursing demands and can be used to optimize the distribution of available care resources. METHODS: This single-center prospective study included patients admitted to the Department of Internal Medicine at the Civil Hospital in Altovicentino (Italy) between September 1 and December 31, 2022. Nursing activities were recorded for the first three days after admission and standardized to the daily mean as performance/5 min/patient/day. Linear regression was used to assess the correlation between nursing demands for different National Early Warning Scores. RESULTS: This study included 333 patients. Their mean National Early Warning Score was 3.9 (standard deviation: 2.9), with 61 % (203/333) in the National Early Warning Score <5 category, 19.5 % (65/333) in the National Early Warning Score 5-6 category, and 19.5 % (65/333) in the National Early Warning Score >6 category. Their average daily care requirements increased from 22 (16-30) activities/5 min/patient/day in the low National Early Warning Score category to 30 (20-39) activities/5 min/patient/day in the intermediate National Early Warning Score category (p < 0.001) and 35 (23-45) activities/5 min/patient/day in the high National Early Warning Score category (p < 0.001). CONCLUSION: The National Early Warning Score correlates with nursing care activities for patients with an acute condition and can be used to optimize the distribution of available care resources.

The role of lactate-to-albumin ratio to predict 30-day risk of death in patients with sepsis in the emergency department: a decision tree analysis.

BACKGROUND: Accurately estimating the prognosis of septic patients on arrival in the emergency department (ED) is clinically challenging. The lactate-to-albumin ratio (LAR) has recently been proposed to improve the predictive performance of septic patients admitted to the ICU. OBJECTIVES: This study aims to assess whether the LAR could be used as an early prognostic marker of 30-day mortality in patients with sepsis in the ED. METHODS: A prospective observational study was conducted in the ED of the Hospital of Merano. All patients with a diagnosis of sepsis were considered. The LAR was recorded on arrival in the ED. The primary outcome measure was mortality at 30 days. The predictive role of the LAR for mortality was evaluated with the area under the ROC curve, logistic regression adjusted for the Charlson Comorbidity Index value, National Early Warning Score, and Sequential Organ Failure score, and with decision tree analysis. RESULTS: 459 patients were enrolled, of whom 17% (78/459) died at 30 days. The median LAR of the patients who died at 30 days (0.78 [0.45-1.19]) was significantly higher than the median LAR of survivors (0.42 [0.27-0.65]) (p < 0.001). The discriminatory ability of the LAR for death at 30 days was 0.738, higher than that of lactate alone (0.692), and slightly lower than that of albumin alone (0.753). The decision trees confirmed the role of the LAR as an independent risk factor for mortality. CONCLUSION: The LAR can be used as an index to better predict the 30-day risk of death in septic patients.

Real requirements of nursing activities and patient-related factors related to nursing overload in an internal medicine department.

Adequate nursing care can be decisive for the outcome of a patient admitted to an internal medicine ward. Individual prediction of nursing activity at the time of a patient's admission could improve the work process. This study aimed to assess the objectively assessed nursing requirements of patients admitted to a medical setting and to identify clinical factors that correlate with high demands. This is a prospective and pragmatic observational study that enrolled patients admitted to the Internal Medicine ward at the Altovicentino Civil Hospital (Italy) between September 1 and December 31, 2022. Nursing activities were recorded for the first 3 days of hospitalization and standardized as performance/5 min/patient. Patients requiring more than the 75th percentile of performance/5 min/patient were considered nursing over-activities. Multivariable models were used to assess patient-related risk factors associated with nursing over-activity. This study enrolled 333 patients (mean age: 74.2; 55.6% male). Their mean Charlson Comorbidity Index (CCI), Clinical Frailty Scale (CFS), Chronic Barthel Index, and Sistema Informtativo della Performance Infermieristica (SIPI) scores were 5.3, 4.2, 62.4, and 53.7, respectively. Mean National Early Warning System (NEWS) on admission was 3.9 (standard deviation: 2.8). A median of 73 (interquartile range [IQR]: 54-109) nursing care activities/5 min/patient were performed. NEWS score (odds ratio [OR]: 1.372, 95% confidence interval [95%CI]: 1.216-1.547, p < 0.001) and Acute Barthel Index (OR: 0.983, 95%CI: 0.967-0.999, p = 0.041) were independent risk factors for nursing over-activities. NEWS and the Acute Barthel Index could help reorganize nursing resources within internal medicine wards, allowing for an equal distribution between patients who require more resources and those who require less.
