This scoping review explores the environmental impact of nursing interventions in acute care settings, focusing on waste reduction, energy consumption, and carbon emissions, while identifying nurse-led sustainability practices, assessment frameworks, and implementation barriers/enablers.
Guided by Arksey and O'Malley's framework and reported per PRISMA-ScR guidelines.
Data Sources: PubMed, CINAHL, Scopus, and Google Scholar were searched for peer-reviewed, English-language studies published between 2020 and 2025. Review Methods: A five-stage process was employed: (1) research question formulation, (2) comprehensive literature search, (3) study selection using the Population–Phenomenon–Context (PPC) framework, (4) data charting via a structured extraction form, and (5) thematic synthesis. Methodological quality was appraised using Joanna Briggs Institute (JBI) tools.
Of 400 identified records, 25 met inclusion criteria. Findings show nurses reduce environmental impact through reusable linen use (e.g., 496 kg/year ICU waste reduction), energy-efficient equipment, and improved waste segregation. However, time constraints, limited resources, and inadequate sustainability training impede consistent implementation. Awareness among nurses and students is moderate but rarely translates into practice.
Nursing interventions hold significant potential to reduce healthcare's environmental footprint. Embedding sustainability competencies into curricula and reinforcing them with institutional policies and leadership support are essential.
This review informs nurses and clinical leaders that sustainable practices—such as switching to reusable linens and optimizing energy use—are both feasible and impactful in acute care. It provides actionable evidence for reducing waste and carbon emissions while maintaining patient safety, supporting the integration of environmental stewardship into daily nursing practice. Findings from this review highlight the measurable environmental benefits of nurse-led sustainability interventions, such as waste reduction and energy conservation in ICUs. The evidence supports updating nursing curricula, clinical guidelines, and hospital policies to equip nurses with the knowledge and tools needed to lead sustainability efforts, thereby reducing healthcare's carbon footprint without compromising care quality.
Pressure ulcers (PUs) (also termed pressure injuries [PIs]) remain a major patient safety issue, particularly in critical care and other high-risk healthcare settings. Nurses are central to PUs/PIs prevention; however, deficiencies in knowledge, attitudes, and preventive practices among nursing staff may negatively affect patient outcomes. To systematically synthesise global evidence on nurses' knowledge, attitudes, and practices related to PUs/PIs prevention, and to identify factors influencing preventive performance. A systematic review was conducted in accordance with PRISMA guidelines. Electronic databases including PubMed, CINAHL, EBSCO, MEDLINE, PsycINFO, and Springer were searched for studies published between 2011 and 2025. Eligible studies were primary research articles examining registered nurses' knowledge, attitudes, and/or practices regarding PUs/PIs prevention, using cross-sectional, observational, or non-experimental designs. Data extraction focused on study characteristics, settings, samples, assessment instruments, and key outcomes related to knowledge, attitudes, and preventive practices. Due to methodological heterogeneity, a narrative synthesis was performed. Twenty-nine studies from diverse geographical regions were included, with sample sizes ranging from 28 to 950 nurses. Overall, nurses' knowledge of PUs/PIs prevention was frequently inadequate, particularly in prevention-specific domains. In contrast, attitudes toward prevention were generally positive across studies. Preventive practices, however, were often suboptimal. Commonly reported barriers included staff shortages, high workload, limited resources, and insufficient institutional support. Higher educational attainment, specialised clinical experience, recent training, and professional seniority were consistently associated with better knowledge, more positive attitudes, and improved preventive practices. Although nurses generally demonstrate positive attitudes toward PUs/PIs prevention, persistent gaps in knowledge and practice remain. These findings underscore the need for structured education programmes, simulation-based training, and strengthened organisational support to enhance adherence to evidence-based prevention strategies. Future research should employ experimental and longitudinal designs, standardised measurement tools, and broader international representation to support sustainable improvements in PUs/PIs prevention and patient safety.
