Real healthcare data (RWD) is an important tool for marketing pharmaceutical products, enabling more accurate targeting of the right doctors and patients[2][4]. By analyzing data from electronic health records and other sources, marketers can identify healthcare providers who frequently diagnose specific diseases and prescribe relevant medications[2]. The global evidence-based solutions market is expected to grow from $4.74 billion in 2024 to $10.83 billion by 2030, representing a compound annual growth rate of 14.8 percent[3]. Real data enables healthcare marketers to move from mass marketing to patient-centric approaches that take into account the social determinants of health and patient behavior[4]. This data helps optimize marketing campaigns in real time and measure their actual impact on prescriptions and doctor visits[4]. The challenge for the future is that while all healthcare marketing leaders will have access to vast amounts of real data, few will have the systems in place to use it intelligently[3].
