Real world data

Last updated

Real world data (RWD) in medicine is data derived from a number of sources that are associated with outcomes in a heterogeneous patient population in real-world settings, including but not limited to electronic health records, health insurance claims and patient surveys. While no universal definition of real world data exists, researchers typically understand RWD as distinct from data sourced from randomized clinical trials. [1]

Real world data (RWD) in healthcare

Real-world data refer to observational data as opposed to data gathered in an experimental setting such as a randomized controlled trial (RCT). They are derived from electronic health records (EHRs), claims and billing activities, product and disease registries, etc. A systematic scoping review of the literature suggests data quality dimensions and methods with RWD is not consistent in the literature, and as a result quality assessments are challenging due to the complex and heterogeneous nature of these data. [2]

The sources of RWD are only rarely interoperable, as each hospital-maintained EHR system is, by design, secured for patient privacy. Healthcare providers responsible for entering patient data into their EHR may agree to pooling that data with others, once it has been de-identified in accordance with privacy regulations such as HIPAA or GDPR. The result is a larger, more heterogenous population for research, where trends and statistical associations may be more apparent. Results from analysis on aggregated RWD can inform the design of clinical study protocols or advance post-approval research. [3]

Real world evidence (RWE)

When working with RWD, the goal is often to generate evidence. The term real world evidence (RWE) is highly related to RWD. RWE is defined by FDA as "clinical evidence regarding the usage and potential benefits or risks of a medical product derived from analysis of RWD". [4] An example of a study utilizing RWE is " Clinical Features and Outcomes of Coronavirus Disease 2019 Among People Who Have HIV in the United States: A Multi-center Study From a Large Global Health Research Network (TriNetX)" In this study, Covid-19 outcomes were compared between people with HIV and HIV-negative controls from a database of de-identified health records. The TriNetX platform allowed the researchers to consider the HIV and HIV-negative subjects in incidence of hospitalizations, ICU admissions, ventilation and severe disease, to understand the impact Covid-19 infection has on those with HIV. [5]

Regional context

US context

In December 2018, the FDA published a framework for Real World Evidence program. [4]

EU context

In 2018, the EMA published a discussion paper on the use of patient disease registries for regulatory purposes (methodological and operational considerations). [6] In 2022, UK's National Institute for Health and Care Excellence published its RWE Framework [7] that sets out how RWE could inform health technology assessment.

The use of real-world data from electronic health records and digital health-monitoring devices is also given as an example of general Post-Market Clinical Followup (PMCF) information for medical devices in the guideline "MDCG 2022-21 Guidance on Periodic Safety Update Report (PSUR) according to Regulation (EU) 2017/745 (MDR)" from December 2022.

Clinical trials are prospective biomedical or behavioral research studies on human participants designed to answer specific questions about biomedical or behavioral interventions, including new treatments and known interventions that warrant further study and comparison. Clinical trials generate data on dosage, safety and efficacy. They are conducted only after they have received health authority/ethics committee approval in the country where approval of the therapy is sought. These authorities are responsible for vetting the risk/benefit ratio of the trial—their approval does not mean the therapy is 'safe' or effective, only that the trial may be conducted.

An electronic health record (EHR) is the systematized collection of patient and population electronically stored health information in a digital format. These records can be shared across different health care settings. Records are shared through network-connected, enterprise-wide information systems or other information networks and exchanges. EHRs may include a range of data, including demographics, medical history, medication and allergies, immunization status, laboratory test results, radiology images, vital signs, personal statistics like age and weight, and billing information.

A clinical decision support system (CDSS) is a health information technology that provides clinicians, staff, patients, and other individuals with knowledge and person-specific information to help health and health care. CDSS encompasses a variety of tools to enhance decision-making in the clinical workflow. These tools include computerized alerts and reminders to care providers and patients, clinical guidelines, condition-specific order sets, focused patient data reports and summaries, documentation templates, diagnostic support, and contextually relevant reference information, among other tools. CDSSs constitute a major topic in artificial intelligence in medicine.

In international trade, market access refers to a company's ability to enter a foreign market by selling its goods and services in another country. Market access is not the same as free trade, because market access is normally subject to conditions or requirements, whereas under ideal free trade conditions goods and services can circulate across borders without any barriers to trade. Expanding market access is therefore often a more achievable goal of trade negotiations than achieving free trade.

A patient safety organization (PSO) is a group, institution, or association that improves medical care by reducing medical errors. Common functions of patient safety organizations are data collection, analysis, reporting, education, funding, and advocacy. A PSO differs from a Federally designed Patient Safety Organization (PSO), which provides health care providers in the U.S. privilege and confidentiality protections for efforts to improve patient safety and the quality of patient care delivery

Artificial intelligence in healthcare is the application of artificial intelligence (AI) to copy or exceed human cognition in the analysis, presentation, and understanding of complex medical and healthcare data. It can augment and exceed human capabilities by providing better ways to diagnose, treat, or prevent disease. Using AI in healthcare has the potential to improve predicting, diagnosing, and treating diseases. Through machine learning algorithms and deep learning, AI can analyze large sets of clinical data and electronic health records, and can help to diagnose diseases more quickly and accurately. In addition, AI is becoming more relevant in bringing culturally competent healthcare practices to the industry.

Health data is any data "related to health conditions, reproductive outcomes, causes of death, and quality of life" for an individual or population. Health data includes clinical metrics along with environmental, socioeconomic, and behavioral information pertinent to health and wellness. A plurality of health data are collected and used when individuals interact with health care systems. This data, collected by health care providers, typically includes a record of services received, conditions of those services, and clinical outcomes or information concerning those services. Historically, most health data has been sourced from this framework. The advent of eHealth and advances in health information technology, however, have expanded the collection and use of health data—but have also engendered new security, privacy, and ethical concerns. The increasing collection and use of health data by patients is a major component of digital health.

Real-world evidence (RWE) in medicine is the clinical evidence regarding the usage and potential benefits or risks of a medical product derived from analysis of real-world data (RWD). RWE can be generated by different study designs or analyses, including but not limited to, randomized trials, including large simple trials, pragmatic trials, and retrospective or prospective observational studies. In the USA the 21st Century Cures Act required the FDA to expand the role of real world evidence.

Learning health systems (LHS) are health and healthcare systems in which knowledge generation processes are embedded in daily practice to improve individual and population health.
