Background: Ministerial Decree (D.M.) 77/2022 aims to reform Italy’s primary care system by establishing community health centres and integrating digital tools to address healthcare access disparities and workforce shortages. This review focuses on frailty assessment tools, digital health innovations, and workforce challenges in the Autonomous Province of Bolzano, South Tyrol, emphasising interprofessional trust and collaboration issues. Methods: Using a narrative custom review approach guided by the SANRA checklist, this study synthesised findings from PubMed, official health websites, and regional surveys on frailty, workforce dynamics, interprofessional collaboration, and digital infrastructure in South Tyrol. Results: General practitioners (GPs) exhibited high professional motivation but expressed concerns about autonomy and administrative burdens in collaborative care models. Trust issues between GPs and specialists hinder workforce cohesion and care coordination, highlighting the need for structured inter-professional communication. Frailty assessments, such as the PRISMA-7 tool, identify over 33% of community-dwelling individuals aged 75 years and older as frail, necessitating targeted interventions. Digital health adoption, particularly electronic health records and telemedicine, is slow because of workforce shortages and infrastructure limitations. Conclusions: The successful implementation of D.M. 77/2022 in South Tyrol requires addressing workforce challenges, improving interprofessional trust, expanding digital infrastructure, and integrating frailty assessment findings into care strategies. These measures are critical for achieving a more resilient, equitable, and effective primary healthcare system.
