Brief Summary

Background and Purpose Community health nursing is essential for providing healthcare to individuals in home and neighborhood settings. As healthcare delivery shifts from hospitals to community environments, nursing students require practical training to develop competencies in conducting home visits. However, the availability of sufficient community-based training sites remains limited, and initial home visit experiences are often associated with student anxiety. This study evaluated whether an immersive virtual reality technology, VR CAVE (Cave Automatic Virtual Environment), can provide training outcomes comparable to traditional practice conducted in a simulated home apartment. VR CAVE generates a room-sized three-dimensional environment that allows users to navigate and interact with realistic home settings without requiring physical props or dedicated space. Methods A crossover randomized controlled trial was conducted with 150 final-year nursing students at the University of Hong Kong from August 2024 to May 2025. Participants were randomly assigned to experience both training modalities in different sequences: one group received VR CAVE training followed by simulated home training, while the other group followed the reverse order. A three-week washout period was implemented between training sessions to minimize carryover effects. Each training session included two realistic home visit scenarios: (1) a 70-year-old male with chronic lung disease living alone with respiratory distress and a urinary catheter, and (2) a 65-year-old female undergoing treatment for tuberculosis in a poorly ventilated apartment. Participants were required to identify environmental hazards, assess patient conditions, and formulate appropriate nursing care decisions. The VR CAVE system projected life-sized three-dimensional home environments onto surrounding walls, incorporating approximately twenty interactive elements per scenario, such as smoke effects, labored breathing sounds, medication containers, and mobility aids. Participants navigated freely within the virtual space and interacted with objects. The traditional simulated home consisted of a physical mock apartment equipped with real props and comparable layouts. Outcomes were measured using validated instruments assessing three domains: self-perceived clinical competence (confidence in nursing skills), self-confidence in applying learned knowledge, and satisfaction with the learning experience. Results Both VR CAVE and traditional simulated home training resulted in significant improvements in clinical competence, self-confidence, and satisfaction. Comparable levels of skill development were observed between participants trained using VR CAVE and those trained in the simulated home. No statistically significant difference in competence scores was identified between the two methods after completion of both training modalities (p=0.345). Higher satisfaction and self-confidence scores were observed following VR CAVE sessions (mean scores ranging from 4.31 to 4.39 out of 5) compared to the simulated home. These findings suggest that the virtual reality approach may offer a more engaging and confidence-enhancing learning experience, despite similar effectiveness in skill acquisition. Significance The findings demonstrate that VR CAVE technology is comparable to traditional hands-on simulation in teaching community nursing skills. Key implications include: Mitigation of space and resource constraints: Virtual environments allow the creation of diverse home settings without reliance on physical infrastructure or repeated reconfiguration of equipment. Expansion of training capacity: Increased access to practice opportunities is achievable without dependence on physical space or clinical placement availability. Enhanced learner engagement: Higher satisfaction levels indicate potential benefits in learner motivation and confidence prior to real-world placements. Adaptability of training scenarios: Virtual environments can be readily modified to represent varied home conditions and patient cases, supporting comprehensive preparation for clinical practice. Overall, VR CAVE represents a valuable adjunct to conventional training methods in preparing nursing students for community-based healthcare roles, particularly in contexts with limited access to real-world training environments.

Outcome Measures

Primary Outcomes (2)

• Change in Self-Perceived Clinical Competence Using Clinical Competence Questionnaire (CCQ) Total Score from Baseline to Post-Test 1

  Self-perceived clinical competence measured using the Clinical Competence Questionnaire (CCQ), a 47-item validated instrument based on Benner's "Novice to Expert" model. The CCQ assesses four domains: nursing professional behaviors, general performance, core nursing skills, and advanced nursing skills. Each item is scored on a 5-point Likert scale. Total CCQ score ranges from 47 to 235, with higher scores indicating greater perceived competence. Change is calculated as post-intervention score minus baseline score. Cronbach's alpha: 0.98.

  Baseline and immediately post-intervention (approximately 20 minutes after completing first simulation session)

• Change in Self-Perceived Clinical Competence Using Clinical Competence Questionnaire (CCQ) Total Score from Baseline to Post-Test 2

  Self-perceived clinical competence measured using the Clinical Competence Questionnaire (CCQ), a 47-item validated instrument based on Benner's "Novice to Expert" model. The CCQ assesses four domains: nursing professional behaviors, general performance, core nursing skills, and advanced nursing skills. Each item is scored on a 5-point Likert scale. Total CCQ score ranges from 47 to 235, with higher scores indicating greater perceived competence. Change is calculated as post-crossover score minus baseline score. Cronbach's alpha: 0.98.

VR CAVE (Cave Automatic Virtual Environment) Simulation for Community Health Nursing

EXPERIMENTAL

Participants receive immersive virtual reality-based home visit simulation using VR CAVE technology. The intervention consists of two 20-minute standardized community health nursing scenarios (COPD patient and tuberculosis patient) projected as life-sized 3D environments with approximately 20 interactive clinical cues per case. Students navigate virtual home settings, identify health hazards, assess patient needs, and apply community nursing principles. Each session is followed by structured debriefing using Kolb's Experiential Learning Theory framework to promote reflection and conceptualization.

Traditional Simulated Home Environment for Community Nursing

ACTIVE COMPARATOR

Participants receive traditional simulation-based home visit training in a physical mock apartment laboratory. The intervention uses the same two 20-minute standardized community health nursing scenarios (COPD patient and tuberculosis patient) with physical props, room layouts, and observational cues mirroring the VR scenarios. Students physically navigate the simulated apartment, identify clinical issues and environmental hazards, and apply community nursing principles. Each session is followed by structured debriefing identical to the VR CAVE arm, using Kolb's Experiential Learning Theory to facilitate reflection and learning.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: SINGLE
• Who Masked: OUTCOMES ASSESSOR
• Masking Details: Due to the nature of the educational intervention, participants and intervention facilitators cannot be blinded to group assignment, as students will be aware of whether they are experiencing VR CAVE or simulated home environments. However, outcome assessors who score and analyze questionnaire responses will be blinded to group allocation. Additionally, the statistical analyst will be blinded to treatment assignment during data analysis to minimize detection and analysis bias.

Model Details: This is a two-period, two-sequence crossover randomized controlled trial. Participants were randomly allocated to one of two sequences: (1) VR CAVE simulation followed by simulated home environment, or (2) simulated home environment followed by VR CAVE simulation. The two intervention periods were separated by a three-week washout period to minimize carryover effects. Each participant experienced both interventions, allowing within-subject comparisons of educational effectiveness. Data were collected at three time points: baseline (T0), after the first intervention (T1), and after the second intervention following crossover (T2). This design controls for individual differences and provides balanced assessment of both simulation modalities.
