The text discusses how healthcare providers can enhance patient care and reduce costs through value-based care, which focuses on patient outcomes rather than service volume, by utilizing real-world evidence (RWE). RWE, derived from sources like electronic health records and wearable devices, offers insights into treatment effectiveness in real-world settings, aiding in the management of chronic illnesses and enabling personalized, preventive care. This approach not only improves patient satisfaction and health outcomes but also enhances care coordination and operational efficiency. However, challenges such as data privacy, ownership, and budget constraints hinder the effective use of RWE. The text suggests that privacy-preserving data analysis technologies, like those offered by Duality, can overcome these obstacles by enabling secure computation of sensitive data, allowing healthcare providers to harness RWE for data-driven decision-making without compromising patient confidentiality. This integration of data privacy and utility is seen as crucial for advancing the value-based care model, ultimately leading to better patient outcomes and lower healthcare costs.
