Introduction Shared Decision-Making Tools (SDMTs) play a pivotal role in facilitating active involvement in health- related decisions by integrating scientific evidence with individual preferences and values. We designed a SDMT in contraception to decide about the contraceptive method based on the preferences, values of the users.

Methods A qualitative research was conducted to explore the users’ experiences and needs for designing a SDMT. The criteria of the International Patient Decision Aid Standards (IPDAS ) were followed. The development involved various stakeholders, including the Agency for Health Quality and Assessment of Catalonia, primary and specialized care gynecologists, midwifes and users. The SDMT launched in 2021 is available in Catalan and Spanish on https://decisionscompartides.gencat.cat/. Currently we are working in an Implementation SMT Guide to assess the tool’s utility for professionals and users. The Guide is based on the Three Talk Model, theoretical approach that describes collaborative deliberation and outlines three broad steps that form the core elements of SDM.

Results The number of users accessing the website has increased in the past few years, reaching164,684 visits in 2024. The co-creation process for the Implementation Guide engaged 9 midwifes and gynecologists, and 2 shared decision-making experts. The aim of the Guide is to facilitate the standardized implementation process in the all the Sexual and Reproductive Care units in Catalonia.

Discussion Research into contraception recognizes that users are more satisfied with the advice received and the method chosen when they experience shared decision-making . The co-creation process, involving both professionals and patients, ensures a comprehensive approach, addressing the needs of all stakeholders.

Conclusions The aim of this Guide is to improve the implementation of SDM in contraception in routine clinical practice, which will lead to greater adherence to treatment and greater encouragement to participation in health.
