Nurse staffing levels in critical care: The impact of patient characteristics

Challenges and peculiarities of nursing activities in intermediate care units compared with internal medicine wards: A prospective study

BACKGROUND

Intermediate Care Units (IMCs) are specialized facilities located within other departments in many Western countries. They are designed to manage patients with conditions that are not severe enough to require an intensive care unit. IMCs aim to fill the gap between regular wards and intensive care units, necessitating an adequate allocation of nursing resources.

AIMS

The aims of the study are to (1) evaluate and compare the nursing workload for patients admitted to a regular ward or to an IMC; (2) quantify nursing workload in terms of activities and time spent to perform them; and (3) evaluate which patient characteristics predict nursing work overload.

STUDY DESIGN AND METHODS

This is an observational, prospective, single-centre study. We included patients admitted to the Internal Medicine department in a general hospital in Italy, between 1 September and 31 December 2022, either in the regular ward or in the IMC. Clinical characteristics, comorbidity, functionality, frailty, severity and acuity of patients were recorded using validated assessment tools. Nursing activities in the first 3 days of hospitalization were recorded and standardized as activities/5 min/patient/day. An average number of nursing activities/5 min/patient/day exceeding the 85th percentile was considered nursing work overload. Multivariate logistic regression models were conducted to identify patient-related risk factors associated with nursing work overload.

RESULTS

We included 333 patients, 55% (183/333) admitted to the IMC and 45% (150/333) to the regular ward. In the IMC, the average nursing activities were 32.4/5 min/patient/day compared with 22.6 in the regular ward. Nursing work overload was found in 6% (9/150) of patients admitted to the regular ward compared with 23% (42/183) in the IMC.

CONCLUSION

There is a significantly higher demand for nursing care among patients in the IMC, with higher daily average of nursing activities.

RELEVANCE TO CLINICAL PRACTICE

The allocation of nursing resources within the IMC should be greater than in the regular ward because of higher workload.

Cross-Cultural Adaptation and Validation of a Surgical Neonatal Nursing Workload Tool for an Italian Context: The Italian Winnipeg Surgical Complex Assessment of Neonatal Nursing Needs Tool

Background: Complexity of care, adequate staffing levels, and workflow are key factors affecting nurses' workloads. There remain notable gaps in the current evidence regarding clinical complexity classification and related staffing adjustment, limiting the capacity for optimal staffing practices. This study aimed to adapt and validate the Winnipeg Surgical Complex Assessment of Neonatal Nursing Needs Tool (WANNNT-SC) for an Italian context to allow the assessment of newborns admitted to NICUs. Methods: This was a validation study. Results: To evaluate the reliability of the tool among different professionals, a correlation test was performed using Pearson's correlation, which revealed a strong correlation (r = 0.967, p = 0.01). In the test-retest phase, there was a significant correlation (r = 0.910 and p = 0.01). Using an analysis of variance, we found that the higher the I-WANNNT-SC score was, the higher the predicted death rate (F = 13.05 and p < 0.001). Conclusions: The Italian Winnipeg Surgical Complex Assessment of Neonatal Nursing Needs Tool represents the first tool available for an Italian context that aims to measure the nursing workload in neonatal intensive care. It could allow adjustments in nursing staffing based on NICU activities and patient needs. This study was prospectively approved by the local Ethics Committee "Palermo 1" (Protocol CI-NICU-00).

Influence of Nursing Time and Staffing on Medication Errors: A Cross-Sectional Analysis of Administrative Data

Background: Medication errors cause adverse events; however, studies have yet to examine medication errors related to nursing hours while considering ward characteristics in Japan. Purpose: This study investigated medication errors caused by nurses to quantitatively assess ward activity as busyness in nursing duties. Methods: This study considered patients hospitalized in the general wards of 10 National Hospital Organization institutions between April 2019 and March 2020. The study data were obtained from the Diagnosis Procedure Combination system, incident report system, and reports on nurse staffing and work hours. Data for 27,629 ward days with 88,475 patients were analyzed. Multivariate analysis was performed to determine the impact of factors on medication errors. Results: The mean patient age was 71.43 years (SD = 15.08). The medication error rate in nursing wards was 13.71%. The mean nursing time per patient during day shift was 1.95 h (SD = 0.58) in the non-medication error group and 2.06 h (SD = 0.58) in the medication error group (p < 0.01). The nursing time per patient in the medication error group compared to that in the non-medication error group had an odds ratio of 1.31 (p < 0.01) during day shifts. Conclusions/Implications for practice: Contrary to evidence, the results showed that medication errors caused by nurses related to increased nurse time with patients during day shifts. Further investigation is needed on the relationship of busyness with nursing duties to ensure an adequate nurse-patient ratio, nursing time, and improved patient safety.

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.

Reliability and validity of the Turkish form of intensive care nursing activities score

BACKGROUND

The purpose of this study was to examine the reliability and validity of the Turkish version of the Nursing Activities Score.

METHODS

To validate the Turkish version of the Nursing Activities Score, a sample comprising 30 adult intensive care patients and 30 nurses was employed. After a pilot study, the internal consistency, Cronbach's alpha coefficient, was found to be p = 0.718. Following the significant internal consistency obtained in the pilot study, the correlation between Nursing Activities Score internal consistency and Critical Nursing Situation Index scores was examined in 150 adult intensive care patients and 150 nurses.

RESULTS

The assessment of inter-rater reliability showed a high level of agreement (99%) and an average Kappa index of 0.598 (p < 0.001). Concurrent validity was demonstrated through a statistically significant correlation between Nursing Activities Score and the Critical Nursing Situation Index (r = 0.71, p < 0.001) and multivariate regression analysis (R2 = 83%, p < 0.001). The validity is supported by the statistically significant relationship between Nursing Activities Score and Critical Nursing Situation Index.

CONCLUSION

These results demonstrate that Nursing Activities Score is a valid and reliable tool for measuring nursing workload in Turkish intensive care units.

Geriatric nursing competence of clinical nursing staff at different hospital levels in Chongqing, China: A cross-sectional study

Objectives

This study aimed to survey the geriatric nursing competencies of clinical nursing staff in Chongqing City, China, and provide suggestions to enhance these competencies.

Methods

This study was conducted in 204 hospitals in Southwest China from December 24, 2022 to January 7, 2023. The "Geriatric Nursing Competence of Clinical Nurse Investigation Tool" was used to explore factors that influence geriatric nurses' competencies via stratified sampling. The survey was conducted by distributing and collecting questionnaires through the online platform Wenjuanxing.

Results

A total of 10,692 nurses answered the questionnaires. Of these questionnaires, 9,442 were valid. The total geriatric nursing competence score of the clinical nursing staff was 2.29 ± 0.81, the secondary hospital score was 2.23 ± 0.78, and the tertiary hospital's overall mean score was 2.33 ± 0.83. The factors that influenced secondary hospitals included the department of medicine, age of nurses and total length of career (P < 0.05). The factors that influenced tertiary hospitals included the department of medicine, age of nurses, nurses' professional title, and geriatric practical advanced nurses' certification (P < 0.05).

Conclusions

Geriatric nursing competence among clinical nursing staff is imbalanced at a lower-middle level and is influenced by various factors. The findings highlight the need for further clinical training in geriatric nursing. The training of geriatric nurses should focus on necessary clinical skills and on preparing them to adequately manage comprehensive geriatric syndromes.

Infection Prevention and Control Strategies According to the Type of Multidrug-Resistant Bacteria and Candida auris in Intensive Care Units: A Pragmatic Resume including Pathogens R0 and a Cost-Effectiveness Analysis

Multidrug-resistant organism (MDRO) outbreaks have been steadily increasing in intensive care units (ICUs). Still, healthcare institutions and workers (HCWs) have not reached unanimity on how and when to implement infection prevention and control (IPC) strategies. We aimed to provide a pragmatic physician practice-oriented resume of strategies towards different MDRO outbreaks in ICUs. We performed a narrative review on IPC in ICUs, investigating patient-to-staff ratios; education, isolation, decolonization, screening, and hygiene practices; outbreak reporting; cost-effectiveness; reproduction numbers (R0); and future perspectives. The most effective IPC strategy remains unknown. Most studies focus on a specific pathogen or disease, making the clinician lose sight of the big picture. IPC strategies have proven their cost-effectiveness regardless of typology, country, and pathogen. A standardized, universal, pragmatic protocol for HCW education should be elaborated. Likewise, the elaboration of a rapid outbreak recognition tool (i.e., an easy-to-use mathematical model) would improve early diagnosis and prevent spreading. Further studies are needed to express views in favor or against MDRO decolonization. New promising strategies are emerging and need to be tested in the field. The lack of IPC strategy application has made and still makes ICUs major MDRO reservoirs in the community. In a not-too-distant future, genetic engineering and phage therapies could represent a plot twist in MDRO IPC strategies.

Impact of Collaborative Nursing Care Delivery on Patient Safety Events in an Emergency Intensive Care Unit: A Retrospective Observational Study

OBJECTIVES

Patient safety events (PSEs) have detrimental consequences for patients and healthcare staff, highlighting the importance of prevention. Although evidence shows that nurse staffing affects PSEs, the role of an appropriate nursing care delivery system remains unclear. The current study aimed to investigate whether nursing care delivery systems could prevent PSEs.

METHODS

This retrospective study was conducted in Japan. The study examined the collaborative 4:2 nursing care delivery system in which 2 nurses are assigned to care for 4 patients, collaborating to perform tasks, and provide care. The cohort receiving care from a collaborative 4:2 nursing care delivery system was labeled the postintervention, whereas the cohort receiving care from a conventional individualized system, in which one nurse provides care for 2 patients, was labeled the preintervention. The primary outcome was the occurrence of PSEs.

RESULTS

The preintervention and postintervention comprised 561 and 401 patients, respectively, with the latter consisting of a younger and more critically ill population. The number of PSEs per 1000 patient-days was not significantly different between the 2 groups (10.3 [95% confidence interval, 7.1-13.5] versus 6.0 [95% confidence interval, 3.2-8.9], P = 0.058). Multiple logistic regression analysis showed that the collaborative 4:2 nursing care delivery system was significantly associated with PSEs (adjusted odds ratio, 0.53; 95% confidence interval, 0.29-0.95; P = 0.037).

CONCLUSIONS

These findings suggest that in an emergency intensive care unit, a collaborative nursing care delivery system was associated with a decrease in PSEs.

Optimizing Pharmacist Team-Integration for ICU Patient Management: Rationale, Study Design, and Methods for a Multicentered Exploration of Pharmacist-to-Patient Ratio

BACKGROUND

The workload of healthcare professionals including physicians and nurses in the ICU has an established relationship to patient outcomes, including mortality, length of stay, and other quality indicators; however, the relationship of critical care pharmacist workload to outcomes has not been rigorously evaluated and determined. The objective of our study is to characterize the relationship of critical care pharmacist workload in the ICU as it relates to patient-centered outcomes of critically ill patients.

METHODS

Optimizing Pharmacist Team-Integration for ICU patient Management is a multicenter, observational cohort study with a target enrollment of 20,000 critically ill patients. Participating critical care pharmacists will enroll patients managed in the ICU. Data collection will consist of two observational phases: prospective and retrospective. During the prospective phase, critical care pharmacists will record daily workload data (e.g., census, number of rounding teams). During the retrospective phase, patient demographics, severity of illness, medication regimen complexity, and outcomes will be recorded. The primary outcome is mortality. Multiple methods will be used to explore the primary outcome including multilevel multiple logistic regression with stepwise variable selection to exclude nonsignificant covariates from the final model, supervised and unsupervised machine learning techniques, and Bayesian analysis.

RESULTS

Our protocol describes the processes and methods for an observational study in the ICU.

CONCLUSIONS

This study seeks to determine the relationship between pharmacist workload, as measured by pharmacist-to-patient ratio and the pharmacist clinical burden index, and patient-centered outcomes, including mortality and length of stay.

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.

Critical Care Nursing in a Resource-Constrained Setting: A Qualitative Study of Critical Care Nurses' Experiences Caring for Patients on Mechanical Ventilation

Introduction

Managing a patient on mechanical ventilation is a vital aspect of clinical scope in intensive and critical care units. In addition, it is a highly technical, intricate, dynamic task requiring extensive knowledge and skills. Little is known about critical care nurses' experiences caring for patients on mechanical ventilation in contexts where resources are constrained, creating an empirical gap in the available body of knowledge.

Objective

This study explored critical care nurses' experiences caring for patients on mechanical ventilators at an intermediate hospital in northeastern Namibia.

Method

The study followed qualitative descriptive and explorative designs. The purposive sample included 13 critical care nurses who had cared for patients on mechanical ventilation for more than 6 months. Data were collected via individual unstructured interviews and analyzed using a reflexive thematic analysis approach.

Results

Four themes and eight subthemes emerged. Varied personal feelings, such as feeling proud, competent, exhausted, traumatized, overwhelmed, and concerns for patients' well-being were experienced by critical care nurses. Participants described learning from colleagues in the unit and expressed concerns about not having postbasic training in critical care nursing. Negative experiences included concerns about community members' misconceptions about critical care units and mechanical ventilators, and challenges with resources, personnel, and admission procedures.

Conclusion

Critical care nurses in resource-constrained settings have positive and negative experiences caring for patients on mechanical ventilators. The findings have implications for the development of support systems for critical care nurses, including induction programs, competence enhancement, psychological support, the development of guiding documents for admission, patient preparation and sensitization of community members. There is a need for this study to be replicated in other resource-constrained contexts where specialized critical care nurses are available.
