While Anonymized Patient-Level Data (APLD) is invaluable, it often comes with significant limitations. Vendor datasets are frequently biased due to variations in channels, geographies, and patient demographics. For example, some vendors might excel in urban areas but lack coverage in rural regions, or they might capture data predominantly from commercial payers, leaving out significant segments of the population. These biases lead to incomplete patient data, resulting in blind spots that can impact strategic decisions.
