Introduction: Leadership significantly influences nurses’ occupational well‐being, particularly their levels of burnout and work engagement, according to the Job Demands‐Resources (JD‐R) model. This model posits that job demands increase burnout, whereas resources, such as leadership, promote work engagement. Objective: To analyze the influence of leadership styles on burnout and work engagement among nurses within the theoretical framework of the JD‐R model. Methods: A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines between July and October 2024 in PubMed, CINAHL, WOS, SCOPUS, PROQuest, and PsycInfo. Quantitative observational studies focused on nurses and evaluating leadership, burnout, and work engagement within the JD‐R model were included. A total of 38 relevant studies were identified and assessed for methodological quality using the STROBE tool. Results: Of the studies, 89.47 were cross‐sectional and 10.53% were longitudinal. Transformational, authentic, and servant leadership styles demonstrated protective effects against burnout and promoted engagement. Transformational leadership emerged as the most frequently studied style, consistently associated with lower burnout levels and higher engagement. Conversely, negative styles such as abusive leadership were linked to increased burnout. Most studies used the Maslach Burnout Inventory (MBI) and the Utrecht Work Engagement Scale (UWES) to measure key variables. Conclusions: Effective leadership is a critical resource for improving nurses’ well‐being and performance. Investing in leadership development programs can reduce burnout and enhance engagement, benefiting both nurses and patients. Future studies should include longitudinal designs and explore innovative approaches, such as secure base leadership.

Background/Objectives: The role of the primary health care nurse has evolved since the Spanish Ministry of Health officially established the professional profile of the nurse specialist in Primary Health Care in 2005. Despite the potential benefits of this new professional profile in the population’s health, their actual scope of practice is still unknown and still largely underutilized. This study aimed to explore demands and expectations of adult primary health care service users regarding the role of the nurse specialist in primary health care. Methods: A nationwide cross-sectional study consisted of a computer-assisted telephone survey to a random sample of 1200 adults living in Spain. A self-developed 19-item instrument assessed population’s perception of the role of the nurse specialist in primary health care. Descriptive, bivariate and logistic regression models explored associations between sociodemographic characteristics with perception of the nurse specialist role. Results: Most participants (82.3%) would choose a nurse specialist in primary health care and consider that the nurse specialist in primary health care should expand their scope of practice requesting diagnostic test (70%) and prescribing medications for chronic diseases (63.8%). Conclusions: Results show a population’s positive perception towards expanding the scope of practice of the nurse specialist in primary health care in the Spanish healthcare system. Primary health care models should acknowledge the potential of expanding the competencies of this professional profile.

Aim: Intensive care unit (ICU) nurses operate in highly demanding environments. Secure base leadership (SBL) has been proposed as a resource to help manage these demands. This study examines the associations between ICU nurses’ perceptions of their supervisor as a secure base leader and their burnout and work engagement (WE), as well as the pattern of indirect statistical associations involving organizational dehumanization (OD) and psychological safety (PS) between SBL and these outcomes. Design: A cross‐sectional study conducted in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. Methods: A total of 305 ICU nurses from Spain completed an online questionnaire comprising established measures assessing SBL, OD, PS, burnout, WE, and sociodemographic variables. Data were analyzed using partial least squares structural equation modeling (PLS‐SEM). Results: The direct associations between SBL and burnout and WE were not statistically significant. SBL was significantly associated with lower OD and higher PS, and OD and PS were significantly associated with lower burnout and higher WE. The final model explained 20% of the variance in burnout and 15% of the variance in WE. Conclusion: SBL was associated with ICU nurses’ burnout and WE in a pattern consistent with indirect statistical associations involving OD and PS, whereas the direct associations between SBL and burnout and WE were not statistically significant. Given the cross‐sectional design, these findings should not be interpreted as evidence of causal or temporal mediation. Implications for Nursing: In highly demanding clinical settings, SBL may represent a relevant leadership resource in relation to more humanized and psychologically safe work environments. Implications for Nursing Policy: Nursing leadership development strategies may benefit from prioritizing PS and addressing OD. Such approaches are consistent with the factors associated with nurses’ well‐being and engagement in high‐pressure healthcare settings.

Background/Objectives: Nurses play a key role in supporting patient adherence to biosimilars, a responsibility that depends on their knowledge and understanding of biological therapies. This study aimed to assess nurses’ knowledge and attitudes toward biosimilars in Spain and to examine the demographic and professional factors that shape them. Methods: A self‑administered, web‑based survey was distributed in Spain between May and June 2024 to evaluate registered nurses’ knowledge and attitudes toward biosimilars. Associations were explored using Spearman’s correlation and Fisher’s exact tests, and predictors were examined through ordinal regression models. Results: A total of 402 nurses responded. 63.7% reported at least basic knowledge of biosimilars. Access to industry‑led training was strongly associated with higher knowledge levels (OR = 11.256; p < .001), whereas lack of awareness of biosimilar use in the workplace was associated with lower knowledge (OR = 0.176; p < .001). Nurses’ confidence in the safety and efficacy of biosimilars increased with knowledge level—from basic (OR = 3.823; p < .001) to intermediate (OR = 4.747; p < .001) and advanced (OR = 14.594; p < .001). Confidence was also greater among nurses working with biosimilars in their units (OR = 3.959; p = .004) and those in hospital ambulatory care services (OR = 2.506; p = .022). Conclusions: Nurses in Spain predominantly demonstrate basic knowledge of biosimilars, emphasizing the need for broader access to training. industry‑led courses emerged as the most relevant modifiable factor for improving both knowledge and confidence. Strengthening collaboration with the pharmaceutical industry may support informed clinical practice and improve patient adherence to biosimilar therapy.

Background/Objectives: Nurses play a key role in supporting patient adherence to biosimilars, which requires adequate knowledge of biological therapies. This study aimed to assess nurses’ knowledge and attitudes toward biosimilars in Spain, representing the first nationwide assessment of Spanish nurses’ knowledge and predictive determinants of reliance on biosimilars. Methods: A self-administered, web-based survey was distributed between May and June 2024. Associations were explored using Spearman’s correlation and Fisher’s exact tests, and predictors were examined with ordinal regression models. Results: A total of 402 nurses responded. Most (63.7%) reported at least basic knowledge of biosimilars. Access to industry-led training was strongly associated with higher knowledge (OR = 11.256; p < 0.001), while lack of awareness of workplace biosimilar use was linked to lower knowledge (OR = 0.176; p < 0.001). Confidence in biosimilar safety and efficacy increased with knowledge level (ORs 3.823–14.594; all p < 0.001) and was higher among nurses working with biosimilars in their units (OR = 3.959; p = 0.004) and in hospital ambulatory care services (OR = 2.506; p = 0.022). Conclusions: Spanish nurses predominantly demonstrate basic knowledge of biosimilars, highlighting the need for broader training access. Industry-led training was the strongest modifiable factor to improve knowledge and confidence. Strengthening collaboration with the pharmaceutical industry may support informed practice and enhance patient adherence to biosimilar therapy.
