Effect of Nursing Workload in Intensive Care Units

Effects of interprofessional practice on nursing workload in hospitals: A systematic review

OBJECTIVE

To synthesise scientific evidence on interprofessional practice in hospital care and the effects on nursing workload.

METHODS

Systematic mixed method review, registered in PROSPERO (CRD42021225627) and conducted in the following databases: CINAHL, Medline, Web of Science and Scopus, with no restrictions on the publication period of the studies. Primary studies were recruited on nurses' interprofessional practice (actions and interactions with other professional categories) in hospitals and the effects on one or more dimensions of nursing workload (quantitative, qualitative, physical, cognitive, emotional, time and variation). Scientific articles available in open access, in English, Spanish or Portuguese, were included. The searches were carried out in January 2021. The studies were evaluated by pairs of independent researchers to verify methodological quality, through the Mixed Method Appraisal Tool, and data extraction. To summarise the studies, thematic analysis was adopted.

RESULTS

A total of 1774 publications were assessed for eligibility and 17 studies were included. Of these, two were mixed methods, four were qualitative, and 11 were quantitative, published between 2011 and 2020. The main scenarios investigated were Intensive Care Units and/or Inpatient Units. During data analysis, three thematic categories emerged: Interprofessional practice in coping with emotional overload; Time dedicated by nurses to professional communication; and Working conditions and patient care. The third category consisted of three subthemes: Conflict and flexibility in the context of practice; Working conditions and interprofessional practice; and Effects on patient care.

CONCLUSIONS

The evidence points to the emotional overload of nurses in the face of uncooperative practices. Interprofessional actions, especially communicative ones, demand nurses' time and impact the care provided. The results contribute to political decisions and health work management.

Precision Automated Critical Care Management: Closed-loop critical care for the treatment of distributive shock in a swine model of ischemia-reperfusion

BACKGROUND

Goal-directed blood pressure management in the intensive care unit can improve trauma outcomes but is labor-intensive. Automated critical care systems can deliver scaled interventions to avoid excessive fluid or vasopressor administration. We compared a first-generation automated drug and fluid delivery platform, Precision Automated Critical Care Management (PACC-MAN), to a more refined algorithm, incorporating additional physiologic inputs and therapeutics. We hypothesized that the enhanced algorithm would achieve equivalent resuscitation endpoints with less crystalloid utilization in the setting of distributive shock.

METHODS

Twelve swine underwent 30% hemorrhage and 30 minutes of aortic occlusion to induce an ischemia-reperfusion injury and distributive shock state. Next, animals were transfused to euvolemia and randomized into a standardized critical care (SCC) of PACC-MAN or an enhanced version (SCC+) for 4.25 hours. SCC+ incorporated lactate and urine output to assess global response to resuscitation and added vasopressin as an adjunct to norepinephrine at certain thresholds. Primary and secondary outcomes were decreased crystalloid administration and time at goal blood pressure, respectively.

RESULTS

Weight-based fluid bolus volume was lower in SCC+ compared with SCC (26.9 mL/kg vs. 67.5 mL/kg, p = 0.02). Cumulative norepinephrine dose required was not significantly different (SCC+: 26.9 μg/kg vs. SCC: 13.76 μg/kg, p = 0.24). Three of 6 animals (50%) in SCC+ triggered vasopressin as an adjunct. Percent time spent between 60 mm Hg and 70 mm Hg, terminal creatinine and lactate, and weight-adjusted cumulative urine output were equivalent.

CONCLUSION

Refinement of the PACC-MAN algorithm decreased crystalloid administration without sacrificing time in normotension, reducing urine output, increasing vasopressor support, or elevating biomarkers of organ damage. Iterative improvements in automated critical care systems to achieve target hemodynamics in a distributive-shock model are feasible.

Professional autonomy among nurses in Saudi Arabian critical care units

BACKGROUND

Professional autonomy is essential in expanding the scope of nursing practice and has been recognized as a top nursing priority.

OBJECTIVE

This study aims to assess Saudi nurses' autonomy level in critical care settings and examine the influence of sociodemographic and clinical characteristics on their autonomy level.

METHODS

A correlational design and a convenience sampling approach were used to recruit 212 staff nurses from five Saudi governmental hospitals in Jouf region of Saudi Arabia. The data were collected through a self-administered questionnaire composed of two sections, including sociodemographic characteristics and the Belgen autonomy scale. The Belgen autonomy scale used in this study measures nurses' autonomy levels and consists of 42 items rated on an ordinal scale. The scale's minimum score of 1 indicates nurses with no authority, while the maximum score of 5 indicates nurses with full authority.

RESULTS

Descriptive statistics revealed that nurses in the sample had a moderate overall work autonomy (M = 3.08), with higher autonomy in patient care decisions (M = 3.25) compared to unit operations decisions (M = 2.91). Nurses had the highest level of autonomy in tasks related to preventing patient falls (M = 3.84), preventing skin breakdown (M = 3.69), and promoting health activities (M = 3.62), while they had the lowest level of autonomy in ordering diagnostic tests (M = 2.27), determining the day of discharge (M = 2.61), and planning the unit's annual budget (M = 2.22). The multiple linear regression model (R2 = 0.32, F (16, 195) = 5.87, p < .001) showed that education level and years of experience in critical care settings were significantly related to nurses' work autonomy.

CONCLUSION

Saudi nurses in acute care settings have moderate professional autonomy, with higher autonomy in making patient care decisions than unit operations decisions. Investing in nurses' education and training could increase their professional autonomy, leading to improved patient care. Policymakers and nursing administrators can use the study's results to develop strategies that promote nurses' professional development and autonomy.

Impact of Wound Dressing Changes on Nursing Workload in an Intensive Care Unit

The objective of this study is to understand how the type of wound dressing changes (routine or frequent) in patients admitted to intensive care units influences nurses' workload. This study used a database of retrospective and analytical observational study from one Portuguese intensive care unit. The sample included 728 adult patients admitted between 2015 and 2019. The nursing workload was assessed by the TISS-28 scale, both at admission and at discharge. The linear regression results show that patients with frequent dressing changes are associated with a higher nursing workload, both at admission (Coef. 1.65; 95% CI [0.53; 2.77]) and discharge (Coef. 1.27; 95% CI [0.32; 2.22]). In addition, age influences the nursing workload; older people are associated with a higher nursing workload (at admission Coef. 0.07; 95% CI [0.04; 0.10]; at discharge Coef. 0.08; 95% CI [0.05; 0.10]). Additionally, an increase in nursing workload at admission would significantly increase the nursing workload at discharge (Coef. 0.27; 95% CI [0.21; 0.33]). The relative stability of the nursing workload over the studied years is also another important finding (the influence of studied years is non-significant). In conclusion, patients with frequent dressing changes presented higher TISS-28 scores when compared with patients with an exchange of routine dressings, which leads to a higher nursing workload.

Care Perceptions in two ICU Nursing Care Delivery Models: A qualitative-comparative approach

OBJECTIVES

Analyzed in compared perspective perceptions about nursing care, nurse-patient interaction, and nursing care outcomes in two ICU nursing staff in a high-complexity hospital institution, whose Nursing are Delivery Models (NCDM) are differentiated by the proportion of nurses and nurse assistants (NA) per team and by the assigned tasks and responsibilities.

METHODS

Particularist ethnography with adaptation to virtual methodologies. It included the sociodemographic characteristics of 19 nurses and 23 NA, 14 semi-structured interviews, review of patients' clinical records, and a focus group. Coding, categorization, inductive analysis, validation of results with participants were conducted and thematic saturation was achieved.

RESULTS

Four themes were identified: i) Professionalized care: a nursing of superior value; ii) senses and feelings of care; iii) nursing workload, generating factors and impacts; and iv) nursing missed care as concrete expression of the nursing workload.

CONCLUSIONS

Compared nursing teams perceived nursing care in different ways, since it was experienced based on the assigned responsibilities and the possibilities of interaction with patients. Nursing care in the NCDM of the ICU with prevalence of direct bedside care by nurses with support from NA, it was perceived as holistic, comprehensive, and empathetic; whereas in the ICU with prevalence of delegated care to NA, it was related with administrative leadership and management of the ICU. Regarding the results, the NCDM of the ICU of direct bedside care by nurses showed better performance in patient safety and was closer to the skill level and legal responsibility of the nursing staff.
