Actualization of evidence‐based nursing in primary, specialized, and social care settings—A cross‐sectional survey

Abstract

Background

Basing practice on evidence is a widely acknowledged requirement for nursing, but shortcomings still exist. An increased understanding of the actualization of evidence-based nursing (EBN) across different nursing contexts is needed to develop better support for EBN and promote uniform high-quality nursing.

Aims

The aim of this study was to compare the actualization of EBN in different organizational contexts in Finland.

Methods

Data for this survey were collected in 2021. The actualization of EBN in primary, specialized, and social care organizations was evaluated with the Actualization of Evidence-Based Nursing instrument, nurses' version, which focuses on individual and organizational-level EBN support structures. Differences between (1) specialized and primary healthcare, and (2) different nursing practice settings were tested with Welch's two sample t-test, the Kruskal–Wallis rank sum test, and the Wilcoxon rank sum test.

Results

Based on nurse (n = 1020) evaluations, those working in specialized healthcare hold more positive attitudes toward EBN (p = .021) and evaluated their organization's methods for monitoring and evaluating nursing practices (p = .004) more positively than those working in primary healthcare. Regarding different nursing practice settings (n = 1241), the most positive results were observed within preventive healthcare where nurses evaluated their attitudes toward EBN, EBN competence, and personal evidence-based practices more positively compared to other nursing practice settings. The results were parallel regarding several organizational structures for EBN. Positive results were also observed within somatic units at university hospitals, and most negative results were within institutional care settings, health centers, and home care settings.

Linking Evidence to Action

There is a need for targeted support to strengthen EBN across different organizational contexts, with special attention to those contexts where nursing professionals with lower education levels work. Future research needs to focus on further analyzing the organizational differences and what can be learned, especially from preventive healthcare but also somatic units at university hospitals.

Intracranial pressure measurement is frequently used for diagnosis in neurocritical care but cannot always accurately predict neurological deterioration. Intracranial compliance plays a significant role in maintaining cerebral blood flow, cerebral perfusion pressure, and intracranial pressure. This study’s objective was to investigate the feasibility of transferring external pressure into the eye orbit in a large-animal model while maintaining a clinically acceptable pressure gradient between intraorbital and external pressures. The experimental system comprised a specifically designed pressure applicator that can be placed and tightly fastened onto the eye. A pressure chamber made from thin, elastic, non-allergenic film was attached to the lower part of the applicator and placed in contact with the eyelid and surrounding tissues of piglets’ eyeballs. External pressure was increased from 0 to 20 mmHg with steps of 1 mmHg, from 20 to 30 mmHg with steps of 2 mmHg, and from 30 to 50 mmHg with steps of 5 mmHg. An invasive pressure sensor was used to measure intraorbital pressure directly. An equation was derived from measured intraorbital and external pressures (intraorbital pressure = 0.82 × external pressure + 3.12) and demonstrated that external pressure can be linearly transferred to orbit tissues with a bias (systematic error) of 3.12 mmHg. This is close to the initial intraorbital pressure within the range of pressures tested. We determined the relationship between intraorbital compliance and externally applied pressure. Our findings indicate that intraorbital compliance can be controlled across a wide range of 1.55 to 0.15 ml/mmHg. We observed that external pressure transfer into the orbit can be achieved while maintaining a clinically acceptable pressure gradient between intraorbital and external pressures.

Sri Lanka is a biodiversity hotspot and one of the richest geographical locations of marine sponges in the Indian ocean. However, the most extensive taxonomical study on Sri Lankan sponge biodiversity dates back ~100 years and only a limited number of studies have been conducted on sponge natural products. In the current study, 35 marine sponge specimens (collected from 16 sponge habitats around Sri Lanka) were identified, microfractionated and evaluated for antibacterial and anticancer assays. In total, 30 species were characterized, of which 19 species gave extracts with antibacterial and/or cytotoxic activities. Microfractionated organic extract of Aciculites orientalis gave the most potent antibacterial activity against Staphylococcus aureus and strongest lymphoma cell toxicity was exhibited by the organic extract of Acanthella sp. Guided by the molecular ion peaks in the bioactive fractions, large-scale extraction of Stylissa massa led to the isolation of three bromopyrrole alkaloids, sceptrin, hymenin and manzacidin A/C. Of these, sceptrin exhibited broad spectrum antibacterial activity against both Escherichia coli and S. aureus (MIC of 62.5 μM against both species). Based on natural product literature, seven promising species were identified as understudied. Their further exploration may lead to the discovery of structurally novel compounds.
