Evaluation of the Impact and Implementation of Social Prescribing in Primary Healthcare Units in Lisbon: A Mixed-Methods Study Protocol

Abstract

Background: Social Prescribing (SP) is an intervention to link users of the primary healthcare services to non-clinical organizations based on the community to tackle social determinants of health. Despite the potential benefits of SP, the effectiveness of this complex intervention remains uncertain. This paper presents the study protocol of the evaluation of the first SP project in Portugal. Methods: A mixed-methods study will be conducted to evaluate the SP project. For the quantitative component, a longitudinal, prospective study with a pre-post design will be performed. Data on patients referred to SP will be collected in four different points in time throughout the intervention, using questionnaires on patients’ health status and sociodemographic characteristics, and scales on patients’ well-being, quality of life and activation. The secondary data will be collected using patients’ medical records and SP’s forms about the referral and social responses elaborated within the intervention. Semi-structured interviews with patients and focus groups with stakeholders will be conducted to assess experiences of participation and improvement suggestions on SP. Conclusion: Comprehensive and complementary evidence will provide insights and learning for the implementation of future SP interventions. This can contribute to inform policy and practice, and to increase investment in social prescribing interventions.
