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 collects and distributes clean trial data, ratings, and evaluations using PRECIS-2. This allows for diverse meta-epidemiological analyses that evaluate the effects of treatment across trials with different levels of pragmatism.
Background
Pragmatic trials provide evidence from the real world that can be used to make clinical decisions. The term "pragmatic" however, is not used in a consistent manner and its definition and assessment require further clarification. The purpose of pragmatic trials is to guide clinical practice and policy decisions, rather than confirm a physiological or clinical hypothesis. A pragmatic trial should aim to be as close as is possible to the real-world clinical practice, including recruitment of participants, setting, designing, delivery and execution of interventions, determining and analysis results, as well as primary analyses. This is a major distinction from explanatory trials (as described by Schwartz and Lellouch1), which are designed to provide more thorough confirmation of an idea.
Truly pragmatic trials should not blind participants or the clinicians. This can result in a bias in the estimates of treatment effects. The pragmatic trials also include patients from different healthcare settings to ensure that the outcomes can be compared to the real world.
Furthermore, trials that are pragmatic must concentrate on outcomes that are important to patients, such as quality of life and

The CRASH trial29 compared a two-page report with an electronic monitoring system for patients in hospitals with chronic heart failure. The trial with a catheter, on the other hand utilized symptomatic catheter-related urinary tract infection as its primary outcome.
In addition to these aspects, pragmatic trials should minimize the procedures for conducting trials and requirements for data collection to cut down on costs and time commitments. Finally pragmatic trials should strive to make their results as applicable to real-world clinical practice as is possible by making sure that their primary method of analysis is based on the intention-to-treat method (as described in CONSORT extensions for pragmatic trials).
Many RCTs which do not meet the criteria for pragmatism, however, they have characteristics that are contrary to pragmatism have been published in journals of varying types and incorrectly labeled as pragmatic. This could lead to misleading claims of pragmaticity, and the use of the term needs to be standardized. The creation of the PRECIS-2 tool, which offers a standard objective assessment of pragmatic characteristics is a good initial step.
Methods
In a practical study it is the intention to inform clinical or policy decisions by showing how an intervention could be integrated into routine care in real-world situations. Explanatory trials test hypotheses regarding the cause-effect relation within idealized settings. Consequently, pragmatic trials may have lower internal validity than explanatory trials and might be more susceptible to bias in their design, conduct and analysis. Despite their limitations, pragmatic research can provide valuable information to make decisions in the context of healthcare.
The PRECIS-2 tool evaluates an RCT on 9 domains, with scores ranging from 1 to 5 (very pragmatist). In this study, the areas of recruitment, organisation and flexibility in delivery, flexible adherence and follow-up were awarded high scores. However, the principal outcome and method of missing data were scored below the practical limit. This indicates that a trial can be designed with effective practical features, yet not compromising its quality.
It is difficult to determine the level of pragmatism that is present in a study because pragmatism is not a have a binary characteristic. Certain aspects of a study may be more pragmatic than other. Furthermore, logistical or protocol modifications during the course of the trial may alter its pragmatism score. Additionally 36% of 89 pragmatic trials identified by Koppenaal and co. were placebo-controlled or conducted before approval and a majority of them were single-center. This means that they are not as common and can only be described as pragmatic in the event that their sponsors are supportive of the absence of blinding in these trials.
A common aspect of pragmatic research is that researchers try to make their findings more meaningful by studying subgroups of the trial sample. This can lead to unbalanced analyses that have lower statistical power. This increases the possibility of omitting or misinterpreting differences in the primary outcomes. In the case of the pragmatic trials included in this meta-analysis, this was a significant problem because the secondary outcomes were not adjusted for variations in baseline covariates.
Furthermore the pragmatic trials may have challenges with respect to the gathering and interpretation of safety data. It is because adverse events are usually self-reported and are susceptible to delays, inaccuracies or coding errors. It is crucial to increase the accuracy and quality of outcomes in these trials.
Results
While the definition of pragmatism doesn't require that clinical trials be 100% pragmatic, there are benefits when incorporating pragmatic components into trials. These include:
Increased sensitivity to real-world issues which reduces the size of studies and their costs, and enabling the trial results to be more quickly implemented into clinical practice (by including patients from routine care). However, pragmatic studies can also have drawbacks. The right kind of heterogeneity, for example could help a study extend its findings to different settings or patients. However the wrong kind of heterogeneity can reduce the sensitivity of an assay, and therefore reduce a trial's power to detect small treatment effects.
A variety of studies have attempted to classify pragmatic trials using different definitions and scoring methods. Schwartz and Lellouch1 created a framework to differentiate between explanation studies that confirm a physiological or clinical hypothesis and pragmatic studies that inform the selection of appropriate treatments in the real-world clinical practice. Their framework included nine domains that were scored on a scale of 1 to 5, with 1 indicating more lucid and 5 indicating more pragmatic. The domains were recruitment, setting, intervention delivery, flexible adherence, follow-up and primary analysis.
The original PRECIS tool3 was built on the same scale and domains. Koppenaal and colleagues10 created an adaptation of the assessment, called the Pragmascope that was simpler to use for systematic reviews. They discovered that pragmatic systematic reviews had a higher average score in most domains, with lower scores in the primary analysis domain.
The difference in the primary analysis domains can be due to the way in which most pragmatic trials analyze data. Certain explanatory trials however don't. The overall score was lower for pragmatic systematic reviews when the domains of organisation, flexible delivery and follow-up were combined.
It is important to remember that a study that is pragmatic does not mean that a trial is of poor quality. In fact,

These terms could indicate that there is a greater understanding of pragmatism in abstracts and titles, but it's unclear whether this is evident in content.
Conclusions
As appreciation for the value of real-world evidence becomes increasingly commonplace, pragmatic trials have gained popularity in research. They are randomized trials that compare real world alternatives to new treatments that are being developed. They include patient populations more closely resembling those treated in regular care. This approach can overcome the limitations of observational research like the biases that are associated with the reliance on volunteers as well as the insufficient availability and codes that vary in national registers.
Other advantages of pragmatic trials include the possibility of using existing data sources, and a higher probability of detecting significant changes than traditional trials. However, pragmatic tests may be prone to limitations that undermine their effectiveness and generalizability. For instance the rates of participation in some trials could be lower than expected due to the healthy-volunteer influence and financial incentives or

The requirement to recruit participants quickly reduces the size of the sample and the impact of many practical trials. In addition certain pragmatic trials don't 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 that self-described themselves as pragmatic and were published until 2022. The PRECIS-2 tool was used to evaluate the degree of pragmatism. It covers areas such as eligibility criteria as well as recruitment flexibility, adherence to intervention, and follow-up. They found that 14 of these trials scored pragmatic or highly practical (i.e. scoring 5 or higher) in one or more of these domains and that the majority of these were single-center.
Trials with high pragmatism scores are likely to have more lenient criteria for eligibility than conventional RCTs. They also contain populations from various hospitals. According to the authors, may make pragmatic trials more relevant and relevant to the daily practice. However, they cannot ensure that a study is free of bias. The pragmatism is not a fixed characteristic and a test that does not possess all the characteristics of an explanatory study may still yield valuable and valid results.
