Abstract Issue Mental Health problems are one of the main causes of disability and morbidity. We think it is pertinent to intervene, providing special care for people with mental disorders and their families. We developed the project “Ajudar” (“To Help”), in a municipality in Northern Portugal. Description of the problem “Ajudar” started in 2013. Its main goal is to contribute to reducing the impact of mental disorders. Its objectives are to identify people with mental disorders treated with long-acting injectables (LAI) and to promote treatment adherence. We identified the Health Units (HU) where these patients take the medication and verified their compliance. An informatic alert was issued when there was non-compliance and we participated in home visits when patients did not show up. We also checked the situation if there was involuntary treatment. We wanted to know if this practice contributed to treatment compliance and to reduce involuntary treatment. Results We gradually identified more people, from 47 in 2013 to 108 in 2024. In 2013, 7 people with mental disorders treated with LAI had an involuntary treatment, whereas in 2019 it was 4. We didn’t analyze data from 2020 to 2022, due to the COVID-19 pandemic. We don’t have the complete data from 2023 yet. Lessons Within the years of “Ajudar”, there was a more than twofold increase in the identified patients and a reduction of almost fourfold of the patients that had an involuntary treatment. Analyzing these data one must be careful due to small numbers bias. We think that a similar project is feasible in other settings. In our response to this Public Mental Health issue, we collaborated with everyone involved with these patients, from health profissionals to resources in the community (social services, community leaders, etc). Key messages • There was a decrease to almost ¾ in the number of patients that had an involuntary treatment. • Involvement with the community is key.
