Experiences and Perceptions of Interprofessional Collaboration Among Spanish Optometrists and Occupational Therapists: A Cross-Sectional Study.

INTRODUCTION: Interprofessional collaboration (IPC) between optometrists and occupational therapists is key to optimising care for people with visual and functional difficulties. This study examines the experiences and perceptions of IPC among both disciplines in Spain, identifies factors shaping collaboration and compares actual collaborative practice with perceived IPC priorities. METHODS: A cross-sectional study was conducted using an online survey. Participants, 138 optometrists and 148 occupational therapists, were categorised into two groups: those with prior collaborative experience (G1 = 92) and those without (G2 = 194). The survey included sociodemographic data, practice fields and perceptions of IPC. Drawing on D'Amour's model, the dimensions of shared goals and vision, internalisation, formalisation and governance-and their related indicators-were analysed. Quantitative data were examined using descriptive statistics, chi-square tests, Fisher's exact tests, Mann-Whitney U tests and Kruskal-Wallis tests. Open-ended responses were analysed descriptively. RESULTS: Only 32.2% of participants reported prior IPC experience, and collaboration was more frequent in paediatric and private settings. Many G2 professionals indicated serving clients with low vision or acquired brain injury without collaborating, highlighting missed opportunities. G1 participants reported a positive impact on practice and professional learning and scored highly in internalisation, indicating trust and mutual understanding. Nevertheless, gaps persisted in shared goals, formalisation and governance. Occupational therapists reported a more client-centred approach than optometrists and perceived some role-boundary barriers. Limited role awareness and uncertainty about referral pathways were expressed by G2. Both groups noted a need for targeted training to support IPC. CONCLUSIONS: IPC between optometrists and occupational therapists in Spain is currently limited and mainly informal. Prior collaborative experience was associated with greater trust and clearer role understanding. Interprofessional education, clear referral pathways and organisational support are essential to strengthen IPC and ensure client-centred, comprehensive care for individuals with visual impairment.
