International variation in length of stay in intensive care units and the impact of patient-to-nurse ratios

Punctuated Entropy in the ICU During COVID-19: Team Nursing and Burnout

BackgroundThe novel demands on hospital capacity arising from the COVID-19 pandemic revealed already-existing systemic weaknesses. Intensive care units experienced a sustained surge capacity and were forced to introduce modified standards of care and practices.PurposeIn this article we use punctuated entropy as a conceptual lens to reveal the impact of the COVID-19 pandemic on Ontario hospitals by drawing attention to the cumulative impact of repeated disaster events on their capacity to recover.MethodsThis qualitative instrumental case study took place at a Medical-Surgical Intensive Care Unit in a university-affiliated teaching community hospital in a large urban center in Ontario, Canada. Twelve healthcare professionals from the ICU participated in in-depth semi-structured interviews.ResultsIn-depth interviews with healthcare providers revealed an already-vulnerable system and the disproportionate impact of COVID-19 on the nursing workforce, compounding pre- burnout and compassion injury.ConclusionThe structure of intensive care and the dynamics of collaborative practices within ICUs are subject to continual reconfiguration, potentially leading to punctuated entropy - a permanent state of a lack of capacity to recover. Disaster recovery planning in healthcare services delivery should not be focussed simply on navigating the 'temporary' effects of a single event, but rather on how the event interacts with the already existing 'pathological' state of the healthcare system. In this way solutions to longitudinal systemic problems in ICU healthcare delivery can be anticipated and plans for mitigation can be put in place.

Mastering the narrative: Precision reporting of risk and outcomes in liver transplantation

Liver transplantation is associated with a high risk of postoperative complications due to the complexity of the surgical procedure, recipient disease severity and the wide range of graft quality, which remains somewhat unpredictable. However, survival rates after transplantation continue to improve and the focus has thus turned to other clinically relevant endpoints including post-transplant complications, patient quality of life and costs. Procedures like liver transplantation offer the entire spectrum of post-surgical events, even in donor-recipient constellations deemed of low risk within recently defined benchmark criteria. The Clavien-Dindo classification and the CCI (comprehensive complication index) were established to assess postoperative morbidity and are widely utilised across surgical specialties. These scores depend on the number and grade of complications, which reflect the interventions required, and are frequently used to assess specific donor-recipient risk profiles and new approaches, such as machine perfusion. However, these scores are associated with inter-observer variability when used in practice, mainly due to the lack of uniform definitions. The concept of benchmarking was recently introduced in surgery and transplantation as a mechanism of standardising expected donor/recipient risk with outcomes within the first year after surgery. However, the management of complications differs significantly worldwide, as does the rating scale assigned to various complications. This may lead to inhomogeneous interpretation of study results, leading to difficulty in assessing the clinical effects of novel preservation technologies and other therapeutics in liver transplantation. This article critically discusses frequent challenges associated with risk and outcome assessment following liver transplantation.

Workload assessment using the nursing activities score in intensive care units: Nationwide prospective observational study in France

BACKGROUND

Within French intensive care units (ICUs), patients are treated with two levels of care (intensive or intermediate) with different nurse-to-patient ratios legally defined.

OBJECTIVES

We aimed to compare the nursing workload associated with these two levels of care.

RESEARCH METHODOLOGY

A nationwide prospective observational study was conducted in France between April and July 2023. Each ICU was allowed to choose its own two-week period of data collection during which the Nursing Activities Score was collected by nurses at patients' bedside, during each shift. The Nursing Activities Score ranges from 20 to 177% and a 100% score represents a nurse per shift. The number of patients per nurse was collected and the Nursing Activities Score per nurse was assessed.

RESULTS

One hundred and five ICUs participated. Overall, 21,665 measurements of Nursing Activities Score per patient and 9,885 Nursing Activities Score per nurse were collected. ICUs were composed by 2083 beds distributed into 1520 (73 %) intensive care beds and 563 (27 %) intermediate care beds. Among the participating units, 93 (89 %) of the teams worked in 2 shifts. Median [p25-p75] Nursing Activities Score per adult patient was 61 % [49-80] for intensive care patients and 47 % [38-61] for intermediate care patients (p < 0.001). Median Nursing Activities Score per nurse for adult population was 127 % [92-167], 143 % [92-198], and 164 % [126-213] for nurses only providing intensive care, only intermediate care or both levels of care, respectively (p < 0.001). A Nursing Activities Score per nurse value >100 % was observed in 71.4 %.

CONCLUSIONS

Nurses' workload was high in the ICU, especially when providing intermediate or mixed levels of care.

IMPLICATIONS FOR PRACTICE

In order to reduce nurses' workload, a review of the nurse-to-patient ratios is expected. Physically separating the two levels of care may be a valuable option.

Analysis of admissions to intensive care units that could be supported on an intermediate care unit

BACKGROUND

Only one third of European countries use intermediate care units (IMCs). An IMC makes it possible to manage patients who do not require intensive care but who need a higher level of nursing care that cannot be provided on the general ward. In Belgium, there are no national criteria for ICU admission or discharge, and no policies regarding IMC care or for differentiating ICU intensity levels.

AIM

The aim of our study was to analyse the profile of ICU patients in Belgium on the basis of registered nursing activity in order to quantify the number of ICU days potentially transferable to an IMC.

STUDY DESIGN

The study was conducted on 310 ICU beds. Patients admitted to the study were recruited during two different one-month periods in 2018 and were included into a prospective database that evaluated nursing workload carried out in 15 hospitals in the French-speaking part of Belgium. The number of ICU days that could be supported on an IMC was defined according to the Nursing Activities Score (NAS) items.

RESULTS

A total of 3279 ICU patients for a total of 13 942 ICU days were included. 4987 days (35.8%) were considered as "transferable" to an IMC. The proportion of ICU days transferable to an IMC was highly variable among hospitals, ranging from 20.4% to 59.5% of all ICU days. On the day of ICU admission, 665/2142 (31.0%) of the patients were already identified as transferable to an IMC; this percentage significantly increased on day 2 (972/2066, 47.1%) and day 3 (650/1390, 46.7%).

CONCLUSIONS

In Belgian ICUs, 35.8% of ICU hospital days, as per recorded NAS, do not necessitate intensive monitoring. These 35.8% of days of ICU hospitalization could be supported on an IMC.

RELEVANCE FOR CLINICAL PRACTICE

In this study, a significant number of days spent in the ICU could be supported on an IMC, this could alleviate the workload of nurses and reduce the occupancy rate of intensive care units.

Factors influencing the turnover of nurses in French intensive care unit-A multicenter interview survey

BACKGROUND

Nurse retention is a major concern in healthcare settings, especially among intensive care units (ICU), in which nurses are highly specialized. The objective was to describe the nurse courses after their entrance into the ICU, their motivation for leaving the ICU, and to identify the independent factors that influenced the nurse resignation from their units.

METHODS

In 3 different centers, every ICU nurse working between 2013 and 2023 was telephonically contacted and was asked to describe their career and, when appropriate, the reasons that influenced their resignation from their units; they rated on a Likert scale of 14 factors that influenced their decision.

RESULTS

Among the 405 nurses who worked in these ICUs between 2013 and 2023, 265 (65.0%) were included in the study, and 93 (35.1%) were still working in their unit. The median time of professional experience of the nurses in their ICU was 5.8 [5.0-7.0] years, and at 10 years, 26.3% [20.4-33.9] of the nurses remained in their unit, 23.8% [17.3-32.8] left the ICU but were still in-hospital nurses, and 22.4% [15.8-31.7] underwent specialization. A minority of nurses resigned and changed their careers (9.5% [5.3-17.0]). The main factors influencing the nurse's resignation from their unit were belonging to Generation Y or Z (HR 1.89 [1.35;2.64]), experiencing symptoms of burnout (2.37 [1.63;3.46]), and pregnancy during the ICU (1.77 [1.41;2.23]). The COVID-19 period was inconsistently associated with nurse resignation depending on the center. The main motivations to leave the unit were organizational (variability of schedule, night shift), personal (willingness to change, personal event), and related to the ICU workload.

CONCLUSION

Nurse retention is an increasing concern, associated with the generational aspects and increased prevalence of burnout. Structural changes will have to be made to reduce the turnover.

The occurrence of pressure injuries and related risk factors in patients undergoing extracorporeal membrane oxygenation for respiratory failure: A retrospective single centre study

INTRODUCTION

Limited data is available regarding the incidence of pressure injuries in patients who have undergone Extracorporeal Membrane Oxygenation (ECMO), a life-saving technique that provides respiratory support for hypoxemia that does not respond to conventional treatment.

AIM

To assess the incidence of pressure injuries and identify the risk factors in Acute Respiratory Distress Syndrome patients receiving ECMO.

METHODS

A retrospective observational study utilizing prospectively collected data was performed in an Italian intensive care unit, between 1 January 2012 and 30 April 2022 enrolling all consecutive patients with Acute Respiratory Distress Syndrome who underwent ECMO.

RESULTS

One hundred patients were included in this study. 67 patients (67%) developed pressure injuries during their intensive care unit stay, with a median of 2 (1-3) sites affected. The subgroup of patients with pressure injuries was more hypoxic before ECMO implementation, received more frequent continuous renal replacement therapy and prone positioning, and showed prolonged ECMO duration, intensive care unit and hospital length of stay compared to patients without pressure injuries. The logistic model demonstrated an independent association between the pO2/FiO2 ratio prior to ECMO initiation, the utilization of the prone positioning during ECMO, and the occurrence of pressure injuries.

CONCLUSIONS

The incidence of pressure injuries was elevated in patients with Adult Respiratory Distress Syndrome who received ECMO. The development of pressure injuries was found to be independently associated with hypoxemia before ECMO initiation and the utilization of prone positioning during ECMO.

IMPLICATIONS FOR CLINICAL PRACTICE

Patients who require ECMO for respiratory failure are at a high risk of developing pressure injuries. To ensure optimal outcomes during ECMO implementation and treatment, it is vital to implement preventive measures and to closely monitor skin health in at-risk areas.

The carbon footprint of critical care: a systematic review

PURPOSE

The provision of healthcare is a substantial global contributor to greenhouse gas (GHG) emissions. Several medical specialties and national health systems have begun evaluating their carbon emission contributions. The aim of this review is to summarise and describe the carbon footprint resulting from the provision of adult, paediatric and neonatal critical care.

METHODS

A systematic search of Embase, Cochrane and Web of Science was performed in January 2023. Studies reporting any assessment of the carbon footprint of critical care were included. No language restrictions were applied. GHG emissions from life cycle assessments (LCA) were reported, in addition to waste, electricity and water use. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline was followed.

RESULTS

In total, 13 studies assessing and describing the environmental impact of 36 adult or paediatric intensive care units (ICUs) were included. Two studies described full LCAs, seven reported waste only, two provided audits of unused medical supplies, one reported electricity use, and one study described a Material Flow Analysis. The estimated carbon emissions from critical care range between 88 kg CO2e/patient/day and 178 kg CO2e/patient/day. The two predominant sources of carbon emissions in critical care originate from electricity and gas use, as well as consumables. Waste production ranged from 1.1 to 13.7 kg/patient/day in the 6 studies where mean waste could be calculated.

CONCLUSION

There is a significant carbon footprint that results from intensive care provision. Consumables and waste constitute important, measurable, and modifiable components of anthropogenic emissions. There remains uncertainty due to a lack of literature, several unstudied areas of carbon emissions from critical care units, and within measured areas, measurement and reporting of carbon emissions are inconsistent.

Unfinished nursing care in intensive care units and the mediating role of the association between nurse working environment, and quality of care and nurses' wellbeing

OBJECTIVES

Unfinished care refers to the situation in which nurses are forced to delay or omit necessary nursing care. The objectives was: 1) to measure the prevalence of unfinished nursing care in intensive care units during the COVID-19 pandemic; 2) to examine whether unfinished nursing care has a mediating role in the relationship between nurse working environment and nurse-perceived quality of care and risk of burnout among nurses.

DESIGN

A national cross-sectional survey.

SETTING

Seventy-five intensive care units in Belgium (December 2021 to February 2022).

MAIN OUTCOME MEASURES

The Practice Environment Scale of the Nursing Work Index was used to measure the work environment. The perception of quality and safety of care was evaluated via a Likert-type scale. The risk of burnout was assessed using the Maslach Burnout Inventory scale.

RESULTS

A total of 2,183 nurse responses were included (response rate of 47.8%). Seventy-six percent of nurses reported at least one unfinished nursing care activity during their last shift. The staffing and resource adequacy subdimension of the Practice Environment Scale of the Nursing Work Index had the strongest correlation with unfinished nursing care. An increase in unfinished nursing care led to significantly lower perceived quality and safety of care and an increase in high risk of burnout. Unfinished nursing care appears to be a mediating factor for the association between staffing and resource adequacy and the quality and safety of care perceived by nurses and risk of burnout.

CONCLUSIONS

Unfinished nursing care, which is highly related to staffing and resource adequacy, is associated with increased odds of nurses being at risk of burnout and reporting a lower level of perceived quality of care.

IMPLICATIONS FOR CLINICAL PRACTICE

The monitoring of unfinished nursing care in the intensive care unit is an important early indicator of problems related to adequate staffing levels, the well-being of nurses, and the perceived quality of care.

Cost-effectiveness of intravenous resuscitation fluids in sepsis patients: a patient-level data analysis in Jordan

AIM

Albumin role as fluid resuscitation in sepsis remains understudied in low- and middle-income countries. This study aimed to evaluate the cost-effectiveness of intravenous (IV) Albumin compared to Crystalloids in sepsis patients using patient-level data in Jordan.

METHODS

This was a retrospective cohort study of sepsis patients aged 18 or older admitted to intensive care units (ICU) at two major tertiary hospitals during the period 2018-2019. Patients information, type of IV fluid, and clinical outcomes were retrieved from medical records, and charges were retrieved from the billing system. A 90-day partitioned survival model with two health states (alive and dead) was constructed to estimate the survival of sepsis patients receiving either Albumin or Crystalloids as IV fluids for resuscitation. Overall survival was predicted by fitting a Weibull model on the patient-level data from the current study. To further validate the results, and to support the assessment of uncertainty, time-dependent transition probabilities of death at each cycle were estimated and used to construct a state-transition patient-level simulation model with 10,000 microsimulation trials. Adopting the healthcare system perspective, incremental cost-effectiveness ratios(ICERs) of Albumin versus Crystalloids were calculated in terms of the probability to be discharged alive from the ICU. Uncertainty was explored using probabilistic sensitivity analysis.

RESULTS

In the partitioned survival model, Albumin was associated with an incremental cost of $1,007 per incremental1% in the probability of being discharged alive from the ICU. In the state-transition patient-level simulation model, ICER was $1,268 per incremental 1% in the probability of being discharged alive. Probabilistic sensitivity analysis showed that Albumin was favored at thresholds >$800 per incremental 1%in the probability of being discharged alive from the ICU.

CONCLUSION

IV Albumin use in sepsis patients might not be cost-effective from the healthcare perspective of Jordan. This has important implications for policymakers to readdress Albumin prescribing practice in sepsis patients.

Cost comparisons and factors related to cost per stay in intensive care units in Belgium

BACKGROUND

Given the variability of intensive care unit (ICU) costs in different countries and the importance of this information for guiding clinicians to effective treatment and to the organisation of ICUs at the national level, it is of value to gather data on this topic for analysis at the national level in Belgium. The objectives of the study were to assess the total cost of ICUs and the factors that influence the cost of ICUs in hospitals in Belgium.

METHODS

This was a retrospective cohort study using data collected from the ICUs of 17 Belgian hospitals from January 01 to December 31, 2018. A total of 18,235 adult ICU stays were included in the study. The data set was a compilation of inpatient information from analytical cost accounting of hospitals, medical discharge summaries, and length of stay data. The costs were evaluated as the expenses related to the management of hospital stays from the hospital's point of view. The cost from the hospital perspective was calculated using a cost accounting analytical methodology in full costing. We used multivariate linear regression to evaluate factors associated with total ICU cost per stay. The ICU cost was log-transformed before regression and geometric mean ratios (GMRs) were estimated for each factor.

RESULTS

The proportion of ICU beds to ward beds was a median [p25-p75] of 4.7% [4.4-5.9]. The proportion of indirect costs to total costs in the ICU was 12.1% [11.4-13.3]. The cost of nurses represented 57.2% [55.4-62.2] of direct costs and this was 15.9% [12.0-18.2] of the cost of nurses in the whole hospital. The median cost per stay was €4,267 [2,050-9,658] and was €2,160 [1,545-3,221] per ICU day. The main factors associated with higher cost per stay in ICU were Charlson score, mechanical ventilation, ECMO, continuous hemofiltration, length of stay, readmission, ICU mortality, hospitalisation in an academic hospital, and diagnosis of coma/convulsions or intoxication.

CONCLUSIONS

This study demonstrated that, despite the small proportion of ICU beds in relation to all services, the ICU represented a significant cost to the hospital. In addition, this study confirms that nursing staff represent a significant proportion of the direct costs of the ICU. Finally, the total cost per stay was also important but highly variable depending on the medical factors identified in our results.

Perception of the safety culture in a critical area

INTRODUCTION

Critical care Area (CCA) is one of the most complex in the hospital system, requiring a high number of interventions and handling of amounts of information. Therefore, these areas are likely to experience more incidents that compromise patient safety (PS).

AIM

To determine the perception of the healthcare team in a critical care area about the patient safety culture.

METHOD

Cross-sectional descriptive study, September 2021, in a polyvalent CCA with 45 beds, 118 health workers (physicians, nurses, auxiliary nursing care technicians). Sociodemographic variables, knowledge of the person in charge in PS and their general training in PS and incident notification system were collected. The validated Hospital Survey on Patient Safety Culture questionnaire, measuring 12 dimensions was used. Positive responses with an average score ≥75%, were defined as an area of strength while ≥50% negative responses were defined as an area of weakness. Descriptive statistics and bivariate analysis: X2 and t-Student tests, and ANOVA. Significance p ≤ 0.05.

RESULTS

94 questionnaires were collected (79.7% sample). The PS score was 7.1 (1.2) range 1-10. The rotational staff scored the PS with 6.9 (1.2) compared to 7.8 (0.9) for non-rotational staff (p = 0.04). A 54.3% (n = 51) was familiar with the incident reporting procedure, 53% (n = 27) of which had not reported any in the last year. No dimension was defined as strength. There were three dimensions that behaved like a weakness: security perception: 57.7% (95% CI: 52.7-62.6), staffing: 81.7% (95% CI: 77.4-85.2) and management support: 69 .9% (95% CI: 64.3-74.9).

CONCLUSIONS

The assessment of PS in the CCA is moderately high, although the rotational staff has a lower appreciation. Half of the staff do not know the procedure for reporting an incident. The notification rate is low. The weaknesses detected are perception of security, staffing and management support. The analysis of the patient safety culture can be useful to implement improvement measures.

Fundamental drivers of nurses' experiences of ICU surging during the coronavirus disease 2019 (COVID-19) pandemic

PURPOSE OF REVIEW

Nurses working in intensive care units have been heavily impacted by the coronavirus disease 2019 (COVID-19) pandemic. This review summarizes the current state of the evidence regarding intensive care nurses experience of the pandemic.

RECENT FINDINGS

The pandemic has had an impact on: nursing workload, the organization of nurse staffing, experiences of staff redeployed into ICU, nurses' perceptions of the safety and quality of patient care, and staff health. In the few comparative studies, mental health was worse for nurses than other healthcare workers in intensive care. Despite some of this evidence being published early in the pandemic, no studies were found to evaluate interventions to improve nurses' experiences.

SUMMARY IMPLICATIONS FOR PRACTICE OR RESEARCH

Many of the adverse impacts of the pandemic are interdependent; for example, reducing nurses' workload is likely to have benefits for mental health indicators.Adverse mental health outcomes are likely to have an impact on future recruitment and retention for intensive care nursing.More studies are needed to understand the longer term impact of the pandemic on intensive care nurses.
