Improving interprofessional collaboration in schools: A cluster-randomized study evaluating the effectiveness of the LOG model on collaboration practices.

Although interprofessional collaboration is emphasized as important in schools, little is known about how it should be organized. We analyzed the effects of an organizational model of interprofessional collaboration, the LOG model. The model aims to improve interprofessional collaboration by identifying and improving various meeting places for collaboration, involving municipal school leaders, principals, staff, and interprofessional collaborators, and by increasing feedback from meeting places in and around schools. In a cluster-randomized design including 35 Norwegian primary schools, 19 schools were randomized to the experimental group and implemented the LOG model, and 16 were randomized to a control group. A total of 142 interprofessional collaborators (e.g., school nurses, social workers, and principals) received a questionnaire prior to randomization, with one- and two-year follow-up. Using a validated scale to measure interprofessional team collaboration, we evaluated the effects of the model on collaborators' perceptions in four dimensions: (a) Reflection on process, (b) Professional flexibility, (c) Newly created professional activities, and (d) Role interdependence. During the first, but not the second year of follow-up, the results demonstrated positive and statistically significant effects of the LOG model on the dimensions Reflection on process (p< .001) and Newly created professional activities (p= .016). Our findings demonstrate the potential of interventions addressing interprofessional collaboration at the organizational level.
