Transforming Communication and Non-Technical Skills in Intermediate Care Nurses Through Ultra-Realistic Clinical Simulation: A Cross-Sectional Study.

: Intermediate care units face growing complexity due to aging populations and chronic illnesses. Non-technical skills such as empathy and communication are crucial for quality care. We aimed to examine the relationship between communication skills, self-efficacy, and sense of coherence among intermediate care nurses. : We conducted an observational, cross-sectional study with 60 intermediate care nurses from three units in a Catalan hospital, Spain. Participants engaged in high-fidelity simulation using geriatric end-of-life scenarios with an ultra-realistic manikin representing a geriatric patient at the end of life. NTSs were measured using validated tools: the Health Professionals Communication Skills Scale (HP-CSS), the General Self-Efficacy Scale, and the Sense of Coherence Questionnaire (OLQ-13). Sessions followed INACSL standards, including prebriefing, simulation, and debriefing phases. : Post-simulation outcomes revealed significant gains in interpersonal competencies, with men reporting higher assertiveness ( = 0.015) and greater satisfaction with both the simulation experience ( = 0.003) and the instructor ( = 0.008), underscoring gender-related perceptions in immersive training. : Ultra-realistic clinical simulation is effective in enhancing NTS among intermediate care nurses, contributing to improved care quality and clearer professional profiles in geriatric nursing.
