Background <p>High-risk pregnancies often result in prolonged hospitalizations, leading to significant emotional and psychological distress for pregnant women and their families. This study aimed to evaluate the implementation of the "Ombrelles" mental health promotion program in a high-risk pregnancy unit in a Canadian tertiary hospital.</p> Methods <p>A comprehensive needs assessment was conducted using both quantitative and qualitative methods, including a literature review, surveys, semi-structured interviews, and expert committee meetings. The findings were used to develop the "Ombrelles" program, which has three main components: an educational component with educational in-person or virtual workshops, online courses and videos, a structured support component with activities promoting socialization and relaxation and the promotion of a supportive environment. Surveys were then conducted among inpatients and hospital staff to measure the relevance and satisfaction regarding this intervention.</p> Results <p>During the first two years of rolling out the program, 123 women admitted in the high-risk pregnancy unit and 30 hospital staff were recruited. Results showed proficient resource utilization, high satisfaction (92.2%), and staff recognition of program relevance (55.2%). The "Ombrelles" program effectively met the identified needs, emphasizing a partnership approach between healthcare teams and patients. Areas for improvement were identified, including addressing technical difficulties and avoiding repetition of themes.</p> Conclusion <p>The "Ombrelles" program effectively addressed the identified needs of pregnant women hospitalized for high-risk pregnancies. It provided essential support, educational resources, and opportunities for socialization. The program's development process emphasized partnership between healthcare teams and patients, ensuring its appropriateness and effectiveness.</p>
