Pragmatic Free Trial Meta
Pragmatic Free Trial Meta is a free and non-commercial open data platform and infrastructure that supports research on pragmatic trials. It shares clean trial data and ratings using PRECIS-2, which allows for multiple and varied meta-epidemiological studies to examine the effects of treatment across trials with different levels of pragmatism, as well as other design features.
Background
Pragmatic studies provide real-world evidence that can be used to make clinical decisions. The term "pragmatic", however, is used inconsistently and its definition and measurement require clarification. The purpose of pragmatic trials is to guide clinical practices and policy choices, rather than verify a physiological hypothesis or clinical hypothesis. A pragmatic trial should try to be as close as is possible to actual clinical practices which include the recruiting participants, setting up, delivery and execution of interventions, determination and analysis results, as well as primary analyses. This is a major distinction between explanation-based trials, as defined by Schwartz & Lellouch1, which are designed to test the hypothesis in a more thorough way.
Truly pragmatic trials should not blind participants or clinicians. This can lead to a bias in the estimates of the effects of treatment. The trials that are pragmatic should also try to attract patients from a variety of health care settings, so that their results can be applied to the real world.
Additionally the focus of pragmatic trials should be on outcomes that are important to patients, like quality of life or functional recovery. This is particularly relevant when trials involve the use of invasive procedures or could have harmful adverse consequences. The CRASH trial29 compared a 2-page report with an electronic monitoring system for patients in hospitals with chronic cardiac failure. The catheter trial28, on the other hand utilized symptomatic catheter-related urinary tract infection as the primary outcome.
In addition to these features pragmatic trials should reduce trial procedures and data-collection requirements to cut costs and time commitments. In the end, pragmatic trials should aim to make their findings as relevant to real-world clinical practices as possible. This can be accomplished by ensuring that their primary analysis is based on the intention to treat method (as described in CONSORT extensions).
Many RCTs that do not meet the requirements for pragmatism but contain features in opposition to pragmatism, have been published in journals of different types and incorrectly labeled as pragmatic. This could lead to false claims about pragmatism, and the usage of the term should be standardised. The creation of the PRECIS-2 tool, which provides a standard objective assessment of practical features is a great first step.
Methods
In a pragmatic trial the goal is to inform clinical or

Explanatory trials test hypotheses concerning the cause-effect relation within idealized environments. In this way, pragmatic trials may have a lower internal validity than studies that explain and are more susceptible to biases in their design analysis, conduct, and design. Despite these limitations, pragmatic trials may provide valuable information to decisions in the context of healthcare.
The PRECIS-2 tool scores an RCT on 9 domains, with scores ranging from 1 to 5 (very pragmatic). In this study, the areas of recruitment, organisation as well as flexibility in delivery flexible adherence,

However, it is difficult to assess how practical a particular trial is since pragmaticity is not a definite quality; certain aspects of a trial can be more pragmatic than others. Additionally, logistical or protocol modifications during the course of the trial may alter its score on pragmatism. In addition, 36% of the 89 pragmatic trials identified by Koppenaal et al were placebo-controlled, or conducted prior to licensing and most were single-center. Thus, they are not very close to usual practice and can only be called pragmatic when their sponsors are accepting of the lack of blinding in such trials.
A common feature of pragmatic research is that researchers attempt to make their findings more relevant by studying subgroups within the trial sample. This can lead to unbalanced analyses with lower statistical power. This increases the possibility of omitting or misinterpreting differences in the primary outcomes. In the case of the pragmatic studies included in this meta-analysis this was a significant problem because the secondary outcomes weren't adjusted for the differences in baseline covariates.
Furthermore, pragmatic trials can also be a challenge in the gathering and interpretation of safety data. This is due to the fact that adverse events are usually self-reported and are prone to delays in reporting, inaccuracies, or coding variations. It is important to improve the quality and accuracy of outcomes in these trials.
Results
While the definition of pragmatism may not mean that trials must be 100 percent pragmatic, there are some advantages to including pragmatic components in clinical trials. These include:
Incorporating routine patients, the trial results are more easily translated into clinical practice. However, pragmatic trials be a challenge. The right kind of heterogeneity for instance could allow a study to generalise its findings to many different settings or patients. However, the wrong type can reduce the sensitivity of an assay and, consequently, lessen the power of a trial to detect small treatment effects.
A variety of studies have attempted to classify pragmatic trials using different definitions and scoring methods. Schwartz and Lellouch1 have developed a framework that can differentiate between explanation studies that prove a physiological hypothesis or clinical hypothesis and pragmatic studies that inform the choice for appropriate therapies in clinical practice. Their framework included nine domains that were scored on a scale ranging from 1 to 5 with 1 indicating more explanatory and 5 indicating more pragmatic. The domains covered recruitment of intervention, setting up, delivery of intervention, flex adherence and primary analysis.
The initial PRECIS tool3 had similar domains and an assessment scale ranging from 1 to 5. Koppenaal et. al10 devised an adaptation of this assessment, known as the Pragmascope, that was easier to use for systematic reviews. They found that pragmatic systematic reviews had higher average scores in the majority of domains, with lower scores in the primary analysis domain.
This distinction in the analysis domain that is primary could be due to the fact that the majority of pragmatic trials process their data in an intention to treat method however some explanation trials do not. The overall score was lower for systematic reviews that were pragmatic when the domains of the organization, flexibility of delivery and follow-up were combined.
It is crucial to keep in mind that a pragmatic study should not necessarily mean a low-quality study. In fact, there is a growing number of clinical trials that use the term "pragmatic" either in their abstracts or titles (as defined by MEDLINE however it is neither precise nor sensitive). These terms could indicate an increased understanding of pragmatism in abstracts and titles, but it's not clear if this is reflected in the content.
Conclusions
In recent years, pragmatic trials are increasing in popularity in research because the value of real world evidence is becoming increasingly acknowledged. They are randomized trials that compare real world treatment options with clinical trials in development. They involve patient populations that are more similar to those who receive treatment in regular care. This approach can overcome the limitations of observational research like the biases that are associated with the reliance on volunteers and the limited availability and the coding differences in national registry.
Other benefits of pragmatic trials include the ability to use existing data sources, and a greater likelihood of detecting meaningful changes than traditional trials. However, these trials could have some limitations that limit their validity and generalizability. For instance, participation rates in some trials may be lower than expected due to the healthy-volunteer effect and incentives to pay or compete for participants from other research studies (e.g. industry trials). A lot of pragmatic trials are restricted by the necessity to recruit participants on time. Additionally, some pragmatic trials do not have controls to ensure that the observed differences are not due to biases in trial conduct.
The authors of the Pragmatic Free Trial Meta identified 48 RCTs self-labeled as pragmatist and published from 2022. They assessed pragmatism using the PRECIS-2 tool, which includes the eligibility criteria for domains, recruitment, flexibility in adherence to intervention, and follow-up. They discovered that 14 of these trials scored as highly or pragmatic practical (i.e., scoring 5 or more) in any one or more of these domains and that the majority of these were single-center.
Trials with high pragmatism scores tend to have broader criteria for eligibility than traditional RCTs. They also include populations from various hospitals. According to the authors, can make pragmatic trials more useful and useful in everyday clinical. However, they don't guarantee that a trial will be free of bias. Furthermore, the pragmatism of the trial is not a fixed attribute A pragmatic trial that does not possess all the characteristics of a explanatory trial can yield valid and useful results.
