Nursing workforce,education, and training challenges to implementing extracorporeal membrane oxygenation services in Australian intensive care units: A qualitative substudy

BackgroundThe use of extracorporeal membrane oxygenation (ECMO) is increasing in the management of critical care patients. ECMO service delivery requires an organisation-supported approach to ensure appropriate resources to deliver training, equipment, capacity, staffing, and the required model of care for quality care delivery. The aim of this nested substudy was to explore challenges specific to nursing staff in ECMO services in Australian intensive care units.MethodsThis was a nested substudy within a qualitative study using semistructured focus group discussions conducted with 83 health professionals, which included 40 nurses. There were 14 focus groups across 14 ECMO centres participating in the binational ECMO (EXCEL) registry of Australia and New Zealand. An inductive thematic analysis focused on the nurse's experiences of the barriers and facilitators for nursing in providing an ECMO service.ResultsFour themes emerged relating to the nurse's experience of implementing ECMO services: workforce requirements, workload demands, models of care, and level of experience. The complexity and intensity of caring for ECMO patients may need to be considered an additional factor in the burnout in critical care nurses. Current nursing ratios and responsibilities in critical care need to be considered, with the opportunity for the development of specialist advanced practitioner nursing roles.ConclusionThis study highlights the challenges for nursing in providing ECMO services in the intensive care setting. The complexity and intensity of ECMO is challenging and leads to concerns regarding burnout and workforce preparedness. New models of care need to be considered to mitigate the barriers for nursing identified across ECMO centres.

Impact of COVID-19 on nursing time in intensive care units in Belgium

IntroductionThe COVID-19 pandemic has had a significant impact on nursing practice in intensive care unit and consequently, on workload.ObjectiveTo assess the nurse-patient ratio required by COVID-19 patients and to identify the factors that influence nursing in this context.DesignThis study was a retrospective observational study that evaluated the ratio using the Nursing Activities Score (NAS).SettingThree Belgian French-speaking hospitals, including five ICUs. Patients included COVID-19 and non-COVID-19 patients.Measurements and main resultsThe study included 95 COVID-19 patients and 1604 non-COVID-19 patients (control group) resulting in 905 and 5453 NAS measures, respectively. The NAS was significantly higher among the COVID-19 patients than in the control group (p = <0.0001). In the COVID-19 group, these higher scores were also observed per shift and uniformly across the three hospitals. COVID-19 patients required more time in the activities of monitoring and titration (χ2 = 457.60, p = <0.0001), mobilisation (χ2 = 161.21, p = <0.0001), and hygiene (χ2 = 557.77, p = <0.0001). Factors influencing nursing time measured by NAS in the COVID-19 patients were age <65 years old (p = 0.23), the use of continuous venovenous hemofiltration (p = 0.002), a high APACHE II score (p = 0.006) and patient death (p = 0.002). A COVID-19 diagnosis was independently associated with an increase in nursing time (OR = 4.8, 95% CI:3.6–6.4).ConclusionsPatients hospitalised in the ICU due to COVID-19 require significantly more nursing time and need an average ratio of almost 1:1.     

Association between nursing cost and patient outcomes in intensive care units: A retrospective cohort study of Belgian hospitals

IntroductionHospitals with better nursing resources report more favourable patient outcomes with almost no difference in cost as compared to those with worse nursing resources. The aim of this study was to assess the association between nursing cost per intensive care unit bed and patient outcomes (mortality, readmission, and length of stay).MethodologyThis was a retrospective cohort study using data collected from the intensive care units of 17 Belgian hospitals from January 01 to December 31, 2018. Hospitals were dichotomized using median annual nursing cost per bed. A total of 18,235 intensive care unit stays were included in the study with 5,664 stays in the low-cost nursing group and 12,571 in the high-cost nursing group.ResultsThe rate of high length of stay outliers in the intensive care unit was significantly lower in the high-cost nursing group (9.2% vs 14.4%) compared to the low-cost nursing group. Intensive care unit readmission was not significantly different in the two groups. Mortality was lower in the high-cost nursing group for intensive care unit (9.9% vs 11.3%) and hospital (13.1% vs 14.6%) mortality. The nursing cost per intensive care bed was different in the two groups, with a median [IQR] cost of 159,387€ [140,307–166,690] for the low-cost nursing group and 214,032€ [198,094–230,058] for the high-cost group.In multivariate analysis, intensive care unit mortality (OR = 0.80, 95% CI: 0.69–0.92, p < 0.0001), in-hospital mortality (OR = 0.82, 95% CI: 0.72–0.93, p < 0.0001), and high length of stay outliers (OR = 0.48, 95% CI: 0.42–0.55, p < 0.0001) were lower in the high-cost nursing group. However, there was no significant effect on intensive care readmission between the two groups (OR = 1.24, 95% CI: 0.97–1.51, p > 0.05).ConclusionsThis study found that higher-cost nursing per bed was associated with significantly lower intensive care unit and in-hospital mortality rates, as well as fewer high length of stay outliers, but had no significant effect on readmission to the intensive care unit..     

The impact of the addition of nurse practitioners to surgical intensive care units: A retrospective cohort study

BackgroundDemand for surgical critical care is increasing, but work-hour restrictions on residents have affected many hospitals. Recently, the use of nurse practitioners (NPs) as providers in the intensive care unit (ICU) has expanded rapidly, although the impacts on quality of care have not been evaluated.ObjectivesTo compare the outcomes of critically ill surgical patients before and after the addition of NPs to the ICU team.MethodsWe conducted a retrospective cohort study in a Taiwanese surgical ICU. We compared the outcomes of patients admitted to ICU during the 2-year period before and after the addition of NPs to the ICU team. Patients admitted in the 1-year transition phase were excluded from comparisons. The primary endpoint was ICU mortality. Secondary endpoints included ICU length of stay and incidence of unplanned extubation.ResultsA total of 8747 patients were included in the study. For all eligible admissions, primary and secondary outcomes did not differ significantly between the two groups. For scheduled ICU admissions, ICU mortality was significantly lower after the addition of NPs (2.2% before vs. 1.1% after addition of NPs, p = 0.014). For unscheduled ICU admissions, ICU mortality did not differ significantly between the two groups. In the multivariate analysis, admission after the addition of NPs was associated with significantly reduced ICU mortality (odds ratio = 0.481; 95% confidence interval = 0.263–0.865; p = 0.015) among scheduled admissions.ConclusionIncorporating NPs in the ICU team was associated with improved outcomes in scheduled admissions to surgical ICU when compared with a traditional, resident-based team.     

Nursing workload assessment in an intensive care unit: A retrospective observational study using the Nursing Activities Score

Background

Nursing Activities Score (NAS) is a promising tool for calculating the nursing workload in intensive care units (ICU). However, data on intensive care nursing activities in Portugal are practically non-existent.

Aim

To assess the nursing workload in a Portuguese ICU using the NAS.

Study Design

Retrospective cohort study developed throughout the analysis of the electronic health record database from 56 adult patients admitted to a six-bed Portuguese ICU between 1 June–31 August 2020. The nursing workload was assessed by the Portuguese version of the NAS. The study was approved by the Hospital Council Board and Ethics Committee. The study report followed the STROBE guidelines.

Results

The average occupancy rate was 73.55% (±16.60%). The average nursing workload per participant was 67.52 (±10.91) points. There was a correlation between the occupancy rate and the nursing workload. In 35.78% of the days, the nursing workload was higher than the available human resources, overloading nurse staffing/team.

Conclusions

The nursing workload reported follows the trend of the international studies and the results reinforce the importance of adjusting the nursing staffing to the complexity of nursing care in this ICU. This study highlighted periods of nursing workload that could compromise patient safety.

Relevance to Clinical Practice

This was one of the first studies carried out with the NAS after its cross-cultural adaptation and validation for the Portuguese population. The nursing workload at the patient level was higher in the first 24 h of ICU stays. Because of the ‘administrative and management activities’ related to the ‘patient discharge procedures’, the last 24 h of ICU stays also presented high levels of nursing workload. The implementation of a nurse-to-patient ratio of 1:1 may contribute to safer nurse staffing and to improve patient safety in this Tertiary (level 3) ICU.     

Risk factors for prolonged stay in cardiac surgery intensive care units

Aims and objectives: To identify the factors that might affect the length of stay in the intensive care unit (ICU‐LOS) among cardiac surgery patients. Background: ICU‐LOS forms an important factor for assessing the effectiveness of the provided nursing care. A number of factors can be accused for increasing patient hospitalization. The nursing workload (NWL), among others, was found to play a significant role as it is closely associated with the quality of care. Design: An observational cohort study among 313 consecutive patients who were admitted to the cardiac surgery intensive care unit of a general, tertiary hospital of Athens, Greece from November 2008 to November 2009. Methods: Data collection was performed by using a short questionnaire (for basic demographic information) and two instruments, the Nursing Activities Score (NAS) and the logistic EuroSCORE, for assessing the NWL and the perioperative risk for each patient respectively. Results: ICU‐LOS of more than 2 days increased with age and was more common among females (p < 0·001 and p = 0·02, respectively). Multivariate logistic regression analysis revealed a positive association between increased perioperative risk and the increased ICU‐LOS [odd ratio (OR) 1·9, 95% confidence interval (CI) 1·0–3·5, p = 0·04], while patients with a first day NAS of more than 61·6% had an almost 5·2 times greater probability to stay in the cardiac surgery unit for more than 2 days (OR 5·2, 95% CI 3·0–8·8, p < 0·001). Conclusions: Increased level of NWL and patient perioperative risk are closely associated with increased ICU‐LOS. Relevance to clinical practice: The correlation between patient perioperative risk and ICU‐LOS encourages the early identification of high‐risk patients for prolonged hospitalization. Furthermore, the relationship between NWL and ICU‐LOS allows the early identification of these patients with the use of an independent nursing tool.     

End-of-life decisions: a cohort study of the withdrawal of all active treatment in intensive care units in the United Kingdom

Objective To describe the epidemiology of active treatment withdrawal in a nationally representative cohort of intensive care units (ICUs) focusing on between-unit differences.Design and setting Cohort study in 127 adult general ICUs in England, Wales and Northern Ireland, 1995 to 2001.Patients 118,199 adult admissions to ICUs.Measurements and results The decision to withdraw all active treatment was made for 11,694 of 118,199 patients (9.9%). There were a total of 36,397 deaths (30.8%) before discharge from hospital, and 11,586 (31.8%) of these occurred after the decision to withdraw active treatment, with no change over time (p=0.54). Considerable variation existed between units regarding the percentage of ICU deaths that occurred after the decision to withdraw active treatment (1.7–96.1%). Median time to death after the decision to withdraw active treatment was 2.4 h; 8% survived more than 24 h. After multilevel modelling, the factors independently associated with the decision to withdraw active treatment were: older age, pre-existing severe medical conditions, emergency surgery or medical admission, cardiopulmonary resuscitation in the 24 h prior to admission, and ventilation or sedation/paralysis in the first 24 h after admission. Substantial between unit variability remained after accounting for case-mix differences in admissions.Conclusions Although we were unable to examine partial withdrawal or withholding of care in this study, we found that the withdrawal of all active treatment is widespread in ICUs in the United Kingdom. There was little change in this practice over the period examined. However, there was considerable variation by unit, even after accounting for patient factors and differences in size and type of ICU, suggesting improved guidelines may be useful to facilitate uniform decision making.All work was completed at the Intensive Care National Audit & Research Centre, which also provided financial support     

Nursing activities score (NAS): A proposal for practical application in intensive care units

For over 30 years in an attempt to demonstrate the cost-benefit ratio of the intensive care unit (ICU) a variety of tools have been developed to measure not only the severity of illness of the patient but also to capture the true cost of nursing workload. In this context, the nursing activities score (NAS) was developed as a result of modifications to the therapeutic interventions scoring system-28 (TISS-28). The NAS is a tool to measure nursing workload ICU and it has been shown to be twice as effective in measuring how nurses spend their time caring for critically ill patients than the TISS-28. This paper discuss the introduction of the NAS into everyday use in an intensive care unit in Brazil and highlights the challenges of standardisation of operational definitions, training requirements and accurate completion of the documentation when using such a tool. The rationale and steps undertaken to achieve this are outlined and the benefits of such a process are highlighted.     

Critical care nursing interventions and the time required for their completion in Intensive Care Units: A Delphi study

ObjectiveTo determine which interventions within the Nursing Interventions Classification are most often applied in intensive care units and to validate the time required for each.MethodologyA three-stage e-Delphi was conducted; 21 panelists were recruited, seven manager nurses and 14 clinical nurses with higher degrees and more than five years experience in intensive care nursing. The first round explored the most common interventions applied. Additionally, panelists were asked to propose others. In the second round, participants reflected on the interventions where no consensus was reached as well as to estimate the time required for each intervention. In the third, panelists were queried about the time required for the interventions for which consensus regarding the time was not reached.ResultsA total of 183 interventions were included; 50% of the “Physiological: Complex” domain. The list included 52 (90%) of the 58 “core interventions for critical care nursing” identified in the Nursing Interventions Classification. The time required for 89.1% of the interventions was the same as in the Nursing Interventions Classification seminal work recommendations.ConclusionResults provide a clear picture of nursing activity in general intensive care units, allows to tailor the Nursing Intervetions Classification in Catalonia context and to confirm findings of previous studies.     

Person-centred care among intensive care unit nurses: A cross-sectional study

ObjectivePractising person-centred care is crucial for nurses in the intensive care unit, as patients have high physical and psychological care needs. We aimed to identify the predictors of person-centred care among nurses working in intensive care settings.MethodsIn this cross-sectional study, 188 intensive care unit nurses at four tertiary hospitals in two cities of South Korea were included. They completed self-reported questionnaires on emotional intelligence, compassion satisfaction, secondary traumatic stress, burnout, and person-centred care. Emotional intelligence was measured using the Korean version of the Wong and Law’s emotional intelligence scale. Compassion satisfaction, secondary traumatic stress, and burnout were measured by the Professional Quality of Life questionnaire (version 5). Person-centred care was measured using the person-centred critical care nursing scale.ResultsMultiple regression identified compassion satisfaction (β = 0.49, p <.001) as the most powerful predictor of person-centred care, followed by emotional intelligence (β = 0.21, p =.004) and intensive care unit career length (β = 0.17, p =.021). These three variables accounted for 31.0 % of the variance in person-centred care.ConclusionsThis study highlights the importance of career length, emotional intelligence, and compassion satisfaction in the promotion of person-centred care among intensive care unit nurses. Nursing management should contemplate specific measures to reduce turnover among experienced intensive care unit nurses and to enhance the factors that promote person-centred care, such as compassion satisfaction and emotional intelligence.     

Triggers and nursing influences on delirium in intensive care units

Among care providers, nurses have the most influence on the occurrence of delirium in patients. To identify and investigate the risk factors associated with delirium and analyse the nurse's influence on delirium, a secondary data analysis approach was used with clinical data from the electronic medical record and health care provider data from the management information systems of a university hospital. Data of 3284 patients (delirium = 688, non‐delirium = 2596) hospitalized in the medical and surgical intensive care units containing 2178 variables were analysed. Donabedian's structure‐process‐outcome model was applied to categorize the factors for multilevel hierarchical logistic regression analysis. Sixteen factors (10 patient factors, 1 provider factor, 1 environmental factor, 2 nursing intervention factors and 2 medical intervention factors) were identified as significant in the final model. Longer intensive care unit experience of nurses did not decrease the risk of delirium. Greater number of nursing intervention needs and greater use of restraints were associated with an increased risk of delirium. The duration of nursing career did not affect the reduction of the risk of delirium. Nurses should therefore endeavour to acquire nursing experience specific for delirium care and attend training courses for delirium management.     

An investigation of light and sound levels on intensive care units in China

BackgroundThe intensive care units’ (ICU) environment is considered clinically relevant sources of stress for patients.ObjectivesTo measure 24-h sound and light levels in 7 ICUs in China [four medical (MICU), two surgical (SICU) and one coronary (CCU) ICUs] and to identify the main sources related to increased sound levels.MethodsSound pressure and light levels were monitored for specific times over a 24-h period using a digital sound level meter and a light detector in 7 ICUs. Sound pressure levels were measured for 20 min every hour. The main events at the time of peak noise levels were recorded. Light levels were measured every 2 h at three locations for each ICU: near a window, in the centre of the room, at eye level of a patient receiving assisted ventilation.ResultsThe mean value of 24-h sound pressure levels exceeded 50 dB(A) in all ICUs, ranging from 56.5 to 70.1 dB(A). The SICUs and CCU had higher sound pressure readings from 0700 h to 1600 h, compared to the MICUs where the sound pressure readings reflected less variability across the 24-h period. Marked differences were observed in luminance levels among various ICUs and also across the 24-h period for all three locations. The mean highest level of nocturnal luminance at eye level of patients receiving assisted ventilation ranged from 15 to 489 lx before midnight (1800–2400 h) and 10 to 239 lx after midnight (2401–0759 h).ConclusionsHigh sound pressure levels are prevalent throughout 24 h in the ICUs, especially in the SICU. Many of the readings exceeded international standards. Peak sound pressure levels were related primarily to staff activities and the alarm sounds of machines. ICU patients are exposed to high levels of artificial light continuously throughout the day and night.
