What is the Real-World Evidence?

RWE Services refer to the sophisticated data management capabilities and analytics tools that CROs, technology companies, and consulting firms provide to help life sciences companies cope with all stages of the RWE lifecycle. Such services, which differ from access to data (data itself), concern the process of evidence creation. They include Data Collection & Integration for curating and harmonizing different types of longitudinal data from claims, EHRs, and registries; Study Design & Execution for creating scientific and regulatory compliant prospective and retrospective studies; and Regulatory & Market Access for writing white papers, value dossiers, and RWE submissions. With 80% of drug approvals utilizing RWD in one way or another today, professional services are required to ensure the rigor of methods used, data provenance, and analytical validity of RWE investments translating into regulatory and market success rather than mere data collection.

Use Cases

• Oncology Indication Expansion: Biotech organizations contract RWE service providers to perform retrospective database analysis using de-identified oncology EHR and claims data in order to determine sub-population of patients with unmet needs and successfully file label expansion.
• Rare Diseases External Control Arm: Pharmaceutical organizations utilize combined registry-based data sets and prospective-observational study services to develop natural history of disease cohort that can be used as synthetic control arm for single-arm Phase II gene therapy trial.
• Hip and Knee Replacement Performance: Medical device organizations use site-centric studies and patient-powered data sets to collect long-term patient-reported outcomes (PROMs) from novel implants in order to showcase their real-world survivorship and effectiveness to national joint registries.
• Cardiovascular Risk Management: Healthcare payers use evidence network services to integrate pharmacy and medical claims data to generate comparative effectiveness research report benchmarking real-world safety of novel anticoagulant against current standard of care.

How AI is Transforming the Real-World Evidence Market

The advent of AI is transforming the field of RWE by increasing the speed of unstructured data extraction and boosting the predictive value of observational studies. Under Data Collection and Integration, the advanced capabilities of AI-enabled NLP solutions can be applied to automatically code complicated clinical parameters such as disease stage and biomarker status from the unstructured data contained in the radiology and physician reports, thus eliminating the high cost of manual chart review and providing researchers with a ready-to-analyze dataset. At the same time, the use of AI-enabled analytics features allows scientists to better control for confounders, detect concealed clusters of patients with the same disease course and predict treatment non-responders, thus adding credibility to the retrospective database analysis. Clinical and regulatory decision-making is now revolving around the use of AI technology. Under Pharmacovigilance, intelligent algorithms are employed to mine information on adverse events from the reports and social media listening channels much faster than it is done by other means.

Market Dynamics

Key Drivers in the Global Real-World Evidence Market

Growing Acceptance of Real-World Evidence by Regulatory Authorities
There is a rising recognition among the key regulatory bodies within the healthcare industry for the value of real-world evidence as an additional source of information. Agencies like the FDA and EMA have been pushing for the application of real-world evidence to be used for approval, labeling extension, and post-marketing activities of drugs. In this way, it will help the pharmaceutical and biotech companies gather more evidence on the performance of their drugs in the real world. The more that the regulatory framework adopts the use of evidence gathered from outside the clinic environment, the more there will be increased demand for real-world evidence solutions.

Expansion of Healthcare Data Sources and Digital Health Infrastructure
Digitization of the healthcare sector has led to the increase in the number of real-world data sources such as electronic medical records, claims databases, pharmacy records, wearables, and patient registries. These sources allow collecting comprehensive information on patient outcomes, care practices, and healthcare resource utilization. Cloud computing, artificial intelligence, and big data technologies allow processing large amounts of information and analyzing it effectively. The growth in investments made by healthcare stakeholders in digital transformation programs leads to better data sources and more real-world data available. This growing data environment is a key factor influencing the expansion of the real-world evidence market.

Restraints in the Global Real-World Evidence Market

Data Privacy and Regulatory Compliance Challenges
Information related to the healthcare of patients, its collection, integration, and use have certain regulations associated with them. Different organizations have to follow several sets of regional regulations pertaining to access to information, storing of such information, transferring the information, and obtaining consent from patients. Compliance in multiple jurisdictions makes the task of handling information difficult and costly for real world evidence companies. The problem of patient confidentiality and cybersecurity adds to the issues of sharing information between different healthcare partners. Differences in regulations in different countries make it difficult to conduct multinational studies for gathering real-world evidence.

Data Quality and Interoperability Limitations
Data gathered from real-world settings usually come from many different sources and, as such, can vary in terms of format, code, and documentation system used. Incomplete, inaccurate, or inconsistent data can have an impact on the quality of evidence produced through such data. Inconsistent documentation, incomplete data sets, and even duplications of patient records represent some of the challenges that arise when dealing with this kind of data. The limited ability of the health care infrastructure to share data can pose another problem. Real-world evidence solutions can become more expensive due to these issues.

Growth Opportunities in the Global Real-World Evidence Market
