Does interprofessional collaboration between care levels improve following the creation of an integrated delivery organisation? The Bidasoa case in the Basque Country

<strong>Introduction: </strong>This article explores the impact of the creation of a new integrated delivery organisation on the evolution of interprofessional collaboration between primary and secondary care levels. In particular, the case of the Bidasoa Integrated Healthcare Organisation is analysed. <strong>Theory and methods: </strong>The evolution of interprofessional collaboration is measured through a validated Spanish questionnaire, with 10 items and a 5-point Likert scale, based on the D’Amour’s model of collaboration [20]. The final sample included 146 observations (doctors and nurses). <strong>Results: </strong>The questionnaire identified a significant improvement on the mean scores for interprofessional collaboration of 0.57 points before and after the intervention. A significant improvement was also found in the two dimensions of the measure of interprofessional collaboration used, with the size of the change being higher for the dimension related to the organisational setting (0.63) than for interpersonal relationships (0.47). <strong>Conclusions: </strong>Before and after the creation of the Bidasoa Integrated Healthcare Organisation, an improvement in the perceived degree of interprofessional collaboration between primary and secondary care levels was observed. This finding supports the benefit of a multilevel and multidimensional approach to integration, as in the described Bidasoa case. <strong>Discussion: </strong>Results on the two dimensions of the measure of interprofessional collaboration used, seem to point to the longer time required for interpersonal relationships to change, compared to the organisational setting
