A consensus driven method to measure the required number of intensive care nurses in Australia

The impact of nursing workforce skill-mix on patient outcomes in intensive care units in Victoria, Australia

Objective

This article aims to examine the impact of nursing workforce skill-mix (percentage of critical care registered nurses [CCRN]) in the intensive care unit (ICU) during a patient's stay.

Design

Registry linked cohort study of the Australian and New Zealand Intensive Care Society Adult Patient Database and the Critical Health Resources Information System using real-time nursing workforce data.

Settings

Fifteen public and 5 private hospital ICUs in Victoria, Australia.

Participants

There were 16,618 adult patients admitted between 1 December 2021 and 30 September 2022.

Main outcome measures

Primary outcome: in-hospital mortality. Secondary outcomes: in-ICU mortality, development of delirium, pressure injury, duration of stay in-ICU and hospital, after-hours discharge from ICU and readmission to ICU.

Results

In total, 6563 (39.5%) patients were cared for in ICUs with >75% CCRN, 7695 (46.3%) in ICUs with 50-75% CCRN, and 2360 (14.2%) in ICUs with <50% CCRN. In-hospital mortality was 534 (8.1%) vs. 859 (11.2%) vs. 252 (10.7%) respectively. After adjusting for confounders, patients cared for in ICUs with 50-75% CCRN (adjusted OR 1.21 [95% CI 1.02-1.45]) were more likely to die compared to patients in ICUs with >75% CCRN. A similar but non-significant trend was seen in ICUs with <50% CCRN (adjusted OR 1.21 [95% CI 0.94-1.55]), when compared to patients in ICUs with >75% CCRN. In-ICU mortality, delirium, pressure injuries, after-hours discharge and ICU length of stay were lower in ICUs with CCRN>75%.

Conclusion

The nursing skill-mix in ICU impacts outcomes and should be routinely monitored. Health system regulators, hospital administrators and ICU leaders should ensure nursing workforce planning and education align with these findings to maximise patient outcomes.

The relationship between nursing skill mix and severity of illness of patients admitted in Australian and New Zealand intensive care units

BACKGROUND

Critically ill patients in the intensive care environment require an appropriate nursing workforce to improve quality of care and patient outcomes. However, limited information exists as to the relationship between severity of illness and nursing skill mix in the intensive care.

OBJECTIVE

The aim of this study was to describe the variation in nursing skill mix across different hospital types and to determine if this was associated with severity of illness of critically ill patients admitted to adult intensive care units (ICUs) in Australia and New Zealand.

DESIGN & SETTING

A retrospective cohort study using the Australia and New Zealand Intensive Care Society Adult Patient Database (to provide information on patient demographics, severity of illness, and outcome) and the Critical Care Resources Registry (to provide information on annual nursing staffing levels and hospital type) from July 2014 to June 2020. Four hospital types (metropolitan, private, rural/regional, and tertiary) and three patient groups (elective surgical, emergency surgical, and medical) were examined.

MAIN OUTCOME MEASURE

The main outcome measure was the proportion of critical care specialist registered nurses (RNs) expressed as a percentage of the full-time equivalent (FTE) of total RNs working within each ICU each year, as reported annually to the Critical Care Resources Registry.

RESULTS

Data were examined for 184 ICUs in Australia and New Zealand. During the 6-year study period, 770 747 patients were admitted to these ICUs. Across Australia and New Zealand, the median percentage of registered nursing FTE with a critical care qualification for each ICU (n = 184) was 59.1% (interquartile range [IQR] = 48.9-71.6). The percentage FTE of critical care specialist RNs was highest in private [63.7% (IQR = 52.6-78.2)] and tertiary ICUs [58.1% (IQR = 51.2-70.2)], followed by metropolitan ICUs [56.0% (IQR = 44.5-68.9)] with the lowest in rural/regional hospitals [55.9% (IQR = 44.9-70.0)]. In ICUs with higher percentage FTE of critical care specialist RNs, patients had higher severity of illness, most notably in tertiary and private ICUs. This relationship was persistent across all hospital types when examining subgroups of emergency surgical and medical patients and in multivariable analysis after adjusting for the type of hospital and relative percentage of each diagnostic group.

CONCLUSIONS

In Australian and New Zealand ICUs, the highest acuity patients are cared for by nursing teams with the highest percentage FTE of critical care specialist RNs. The Australian and New Zealand healthcare system has a critical care nursing workforce which scales to meet the acuity of ICU patients across Australia and New Zealand.

Tracheal extubation of the adult intensive care patient with a predicted difficult airway - a narrative review

Management of the difficult airway is an important, but as yet poorly-studied, component of intensive care management. Although there has been a strong emphasis on prediction and intubation of the difficult airway, safe extubation of the patient with a potentially difficult airway has not received the same attention. Extubation is a particularly vulnerable time for the critically ill patient and, because of the risks involved and the consequences of failure, it warrants specific consideration. The Royal College of Anaesthetists 4th National Audit Project highlighted differences in the incidence and consequences of major complications during airway management between the operating room and the critical care environment. The findings in the section on Intensive Care and Emergency Medicine reinforce the importance of good airway management in the critical care environment and, in particular, the need for appropriate guidelines to improve patient safety. This narrative review focuses on strategies for safe extubation of the trachea for patients with potentially difficult upper airway problems in the intensive care unit.

Consensus forum: worldwide guidelines on the critical care nursing workforce and education standards

This article explores the key themes, evidence, and arguments that inform the current position statements. It is acknowledged that future research, evidence, and practice experience may create the need to review and change these guidelines. Reform and refinement of the guidelines are inevitable; however, the current guidelines represent the best attempt yet to reach international consensus on what are appropriate standards to guide critical care nursing education and workforce requirements.

The impact of an ICU liaison nurse on discharge delay in patients after prolonged ICU stay

The mismatch between intensive care unit (ICU) bed availability and demand may be improved with timely patient discharges, however little is known about the nature and contributing factors of discharge delays. This study investigated the impact of a specific intervention--the ICU liaison nurse role--in reducing ICU discharge delay using a prospective block intervention study. One hundred and eighty-six ICUpatients (101 control and 85 liaison nurse intervention) with an ICU length of stay of three days or longer and who survived to ICU discharge were examined. The liaison nurse was involved in assessment of patients for transfer to the ward, with a major focus on coordinating patient transfer including liaison with ward staff prior to and following ICU discharge. Logistic regression was used to quantify the risk of discharge delay associated with the liaison nurse intervention with adjustment for potential confounding variables. While no demographic or clinical variables were significant predictors of ICU discharge delay, those in the liaison nurse group were almost three times less likely to experience a discharge delay of at least two hours and about 2.5 times less likely to experience a delay of four or more hours. The positive effect of the liaison nurse role in reducing the discharge delay remained after adjustingforpotential confounders. We conclude that the liaison nurse role is effective in reducing the discharge delay in ICU transfer

Recommendations for the structure, organization, and operation of intensive cardiac care units

Two major changes in patient characteristics and management occurred recently that demand distinctive alterations in the function of the intensive cardiac care unit (ICCU). These changes include the introduction of an early invasive strategy for the treatment of acute coronary syndromes, enabling early recuperation and shorter need for intensive care on the one hand, while the number of older and sicker patients requiring prolonged and more complex intensive care is steadily increasing. A task force of the European Society of Cardiology Working Group on Acute Cardiac Care was set to give a modern updated comprehensive recommendations concerning the structure, organization, and function of the modern ICCUs and intermediate cardiac units. These include the statement that specially trained cardiologists and cardiac nurses who can manage patients with acute cardiac conditions should staff the ICCUs. The optimum number of physicians, nurses, and other personal working in the unit is included. The document indicates the desired architecture and structure of the units and the intermediate cardiac unit and their relations to the other facilities in the hospital. Specific recommendations are also included for the minimal number of beds, monitoring system, respirators, pacemaker/defibrillators, and necessary additional equipment. The desired function is discussed, namely, the patients to be admitted, the length of stay, and the relocation policy. A uniformed electronic chart for ICCUs is advised, anticipating a common European database.

Pandemic influenza-implications for critical care resources in australia and new zealand

OBJECTIVES

To quantify resource requirements (additional beds and ventilator capacity), for critical care services in the event of pandemic influenza.

MATERIALS AND METHODS

Cross-sectional survey about existing and potential critical care resources. Participants comprised 156 of the 176 Australasian (Australia and New Zealand) critical care units on the database of the Australian and New Zealand Intensive Care Society (ANZICS) Research Centre for Critical Care Resources. The Meltzer, Cox and Fukuda model was adapted to map a range of influenza attack rate estimates for hospitalisation and episodes likely to require intensive care and to predict critical care admission rates and bed day requirements. Estimations of ventilation rates were based on those for community-acquired pneumonia.

RESULTS

The estimated extra number of persons requiring hospitalisation ranged from 8,455 (10% attack rate) to 150,087 (45% attack rate). The estimated number of additional admissions to critical care units ranged from 423 (5% admission rate, 10% attack rate) to 37,522 (25% admission rate, 45% attack rate). The potential number of required intensive care bed days ranged from 846 bed days (2 day length of stay, 10% attack rate) to 375,220 bed days (10 day length of stay, 45% attack rate). The number of persons likely to require mechanical ventilation ranged from 106 (25% of projected critical care admissions, 10% attack rate) to 28,142 (75% of projected critical care admissions, 45% attack rate). An additional 1,195 emergency ventilator beds were identified in public sector and 248 in private sector hospitals. Cancellation of elective surgery could release a potential 76,402 intensive care bed days (per annum), but in the event of pandemic influenza, 31,150 bed days could be required over an 8- to 12-week period.

CONCLUSION

Australasian critical care services would be overwhelmed in the event of pandemic influenza. More work is required in relation to modelling, contingency plans, and resource allocation.

"Realising the potential of critical care nurses": an exploratory study of the factors that affect and comprise the nursing contribution to the recovery of critically ill patients

BACKGROUND

This study seeks to make evident the complexity of issues associated with the delivery of care by nurses to the critically ill. Emphasis had been placed on the results and implications of these for nursing practice. For a more in-depth account, the full report can be accessed on www.lscn.co.uk.

METHOD

Following multi-centre research ethics committee approval, 10 critical care units participated in the 3-month study. Data collection comprised 231 nurse interviews and 51 relative interviews during 33 observation participation periods.

RESULTS

Analysis demonstrated that the context of the critical care unit, in terms of geographical layout, unit activity, case mix and skill mix of nurses, had a major effect on the ability of nurses to contribute to the recovery of the critically ill. The effectiveness of the nursing resource appeared to be a function of knowledge (theoretical and patient related), experience and exposure. Nurses who were unused to a particular environment were not seen to be as effective as those who were. A model was constructed that identified the central tenets upon which nursing care can be optimised or compromised. When nursing care was optimised the difference nurses made potentially decreased risk to patients, enabled timely patient progression and increased the potential for patient recovery.

CONCLUSIONS

The results confirm that nurses have a significant contribution to make in the recovery of patients who have experienced critical illness. Recommendations are far reaching and include the need to develop a valid and reliable tool which addresses patients' need for nursing in terms of nurses' knowledge and experience, patient dependency and decreasing clinical risk across the continuum of care. Current nursing workload tools and patient:nurse ratios were seen to lack validity because they do not appraise the context in which care is delivered, define all nurses as equal and concentrate on activity rather than the effect nurses can have on the outcome of the critically ill.
