Editorial: Real world evidence, outcome research and healthcare management improvement through real world data (RWD)

Editorial on the Research Topic Real world evidence, outcome research and healthcare management improvement through real world data (RWD) The systematic use of Real World Data (RWD) in clinical practice and the real-time application of clinical epidemiology to clinical healthcare and management decision-making processes represent one of the healthcare innovations with the most significant possible impact on the sustainability of healthcare systems and the appropriateness of clinical decisions (1)(2)(3)(4). For this to be possible, the quality of the data, the analysis performed, and their availability must be adequate to answer the science question; it should be systematically recorded and compliant with the FAIR principles: findable, accessible, interoperable and reusable.
Nowadays, Electronic Health Records (EHR) potentially allow the recording and availability of truthful, accurate, and timely data for appropriate and reliable informed decision-making. Clinician-reported patients' health data, Medical Devices-reported data, and Administrative Databases nourish those medical records; even patients' quality of life (QoL) information is being increasingly recorded ( Figures 1B,C). However, this opportunity hinges on the quality of the data; if the data has quality and reliability, the conclusions obtained provide value to the decision-making process; if this is not the case, it can generate biases that jeopardize the appropriateness of the decisions.
The new epistemological paradigm within learning organizations implies having procedures and methods to evolve from data acquisition to evidence generation. For that, standardization, normalization, and structured data recording are prerequisites to an appropriate analysis and comparison of the data and, therefore, to transform data into knowledge. For that, there are four critical aspects of evidence-generating information systems ( patient information directly in the HIS nor is patient experience systematically recorded. As shown in Figure 1A, health professionals introduce patient health outcomes and experience information, including biases and missing information. This paradigm change would impact the whole healthcare/society relationship and medical epistemology. The traditional XX-century Epistemological Paradigm in Medicine ( Figure 1A) introduces data slowly in the system, generating knowledge as slowly as the data is gathered. However, this knowledge management system shows more fragmentation. Still, it has several ways to check the scientific evidence underneath the results and conclusions, ensuring comparability and reliability, such as peer review and scientific Frontiers in Public Health frontiersin.org . /fpubh. . forum discussion. Keeping biases and errors under control was very time-consuming. The New Epistemological Paradigm in Medicine, represented in Figure 1B, changes those facts, incorporating evidence from clinical studies into the decision-making process in real-time. Real-time is understood to be within reasonable parameters in the care process (days or weeks). This epistemological change, illustrated in Figure 1B, is one of the main challenges to be faced by the healthcare systems. Information systems are critical elements in this evolution, together with the adequate training of professionals and citizens (present and future patients, after all). With this Research Topic, we wanted to capture at least part of the complexity of this transformation.
The EHR enables quality data collection and should be the source of information for primary (healthcare, quality and safety, management) and secondary use of data (clinical research) (Figure 2). Therefore, the following should be warranted, normalization and standardization of data and codification with international standards (ICD-10, SNOMED, LOINC...) so the portability of data and data sharing becomes a reality. Adequate data recording, analysis and visualization tools should be developed at different levels of decision-making (clinical management, quality and safety management, and health management). It allows for response to the various information needs or "outputs" (Figure 2) of the institution and its professionals and the creation of automated alerts (triggers) to detect risks and security incidents. Furthermore, all this has to be done at any geographical location or sociodemographic situation within the current global health reality.
Thus, Saha et al. brought us the paramount need to teach and educate professionals (intermediate and final users of the HIS), giving them the knowledge and tools to adapt to these abrupt changes appropriately. Never in history change have been so fast, and healthcare professionals are supposed to adapt as quickly and adequately to them as possible, often without completely understanding the true nature or consequences of the innovations they use. On the other hand, we will need technological innovations to support those changes; Marks et al. brought us the software to make data recording possible in no-so-easy circumstances and with significant public health implications. Moreover, this quick data recording and analysis has to help with the rapid changes in healthcare logistics. If we want to be effective and do the appropriate procedure or treatment for the right patient at the right moment, we must have the resources to do so.
