Pragmatic Free Trial Meta
Pragmatic Free Trial Meta is a free and non-commercial open data platform and infrastructure that facilitates research on pragmatic trials. It is a platform that collects and shares clean trial data and ratings using PRECIS-2 which allows for multiple and varied meta-epidemiological studies to evaluate the effect of treatment on trials that have different levels of pragmatism as well as other design features.
Background
Pragmatic trials are becoming more widely acknowledged as providing evidence from the real world for clinical decision-making. However, the usage of the term "pragmatic" is not consistent and its definition as well as assessment requires clarification. Pragmatic trials should be designed to guide clinical practice and policy decisions, rather than to prove an hypothesis that is based on a clinical or physiological basis. A pragmatic study should strive to be as close as possible to the real-world clinical practice, including recruiting participants, setting up, delivery and implementation of interventions, determination and analysis outcomes, and primary analyses. This is a significant difference from explanatory trials (as described by Schwartz and Lellouch1) that are intended to provide a more complete confirmation of a hypothesis.
Truly pragmatic trials should not blind participants or the clinicians. This can result in bias in the estimations of the effect of treatment. The trials that are pragmatic should also try to attract patients from a variety of health care settings, to ensure that their findings can be compared to the real world.
Furthermore studies that are pragmatic should focus on outcomes that are crucial to patients, such as quality of life or functional recovery. This is especially important in trials that require the use of invasive procedures or could have harmful adverse consequences. The CRASH trial29, for example, focused on functional outcomes to compare a 2-page case-report with an electronic system for monitoring of hospitalized patients with chronic heart failure. Similarly, the catheter trial28 focused on urinary tract infections that are symptomatic of catheters as its primary outcome.
In addition to these characteristics pragmatic trials should reduce the trial procedures and requirements for data collection to reduce costs. In the end, pragmatic trials should aim to make their results as relevant to actual clinical practices as they can. This can be achieved by ensuring that their analysis is based on the intention-to treat method (as described within CONSORT extensions).
Many RCTs which do not meet the requirements for pragmatism but have features that are in opposition to pragmatism, have been published in journals of various types and incorrectly labeled pragmatic. This can lead to false claims of pragmaticity and the usage of the term must be standardized. The development of a PRECIS-2 tool that offers a standardized objective evaluation of pragmatic aspects is a first step.
Methods
In a pragmatic research study, the goal is to inform clinical or policy decisions by showing how an intervention can be integrated into routine care in real-world settings. This differs from explanation trials, which test hypotheses about the cause-effect connection in idealized settings. In this way, pragmatic trials could have lower internal validity than explanatory studies and be more susceptible to biases in their design analysis, conduct, and design. Despite these limitations, pragmatic trials can be a valuable source of information for decision-making in healthcare.
The PRECIS-2 tool evaluates an RCT on 9 domains, with scores ranging from 1 to 5 (very pragmatic). In this study, the areas of recruitment, organization and flexibility in delivery, flexible adherence, and follow-up received high scores. However, the primary outcome and method of missing data were scored below the practical limit. This suggests that it is possible to design a trial with high-quality pragmatic features, without compromising the quality of its results.
It is difficult to determine the amount of pragmatism in a particular trial because pragmatism does not possess a specific attribute. Certain aspects of a study may be more pragmatic than other. A trial's pragmatism could be affected by modifications to the protocol or the logistics during the trial. Additionally 36% of 89 pragmatic trials identified by Koppenaal and co. were placebo-controlled or conducted prior to licensing, and the majority were single-center. They are not close to the norm, and can only be considered pragmatic if their sponsors agree that such trials are not blinded.
A typical feature of pragmatic research is that researchers attempt to make their findings more meaningful by analyzing subgroups of the trial sample. However, this often leads to unbalanced comparisons with a lower statistical power, which increases the likelihood of missing or misinterpreting the results of the primary outcome. In the case of the pragmatic studies included in this meta-analysis, this was a significant problem since the secondary outcomes were not adjusted for variations in the baseline covariates.
Furthermore, pragmatic trials can also be a challenge in the gathering and interpretation of safety data. It is because adverse events are typically self-reported and are susceptible to delays, inaccuracies or coding errors. It is therefore important to improve the quality of outcomes assessment in these trials, and ideally by using national registries rather than relying on participants to report adverse events in the trial's own database.
Results
While the definition of pragmatism may not require that all trials be 100 100% pragmatic, there are advantages to incorporating pragmatic components into clinical trials. These include:
Enhancing sensitivity to issues in the real world, reducing study size and cost, 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. For example, the right kind of heterogeneity can allow a study to generalize its results to many different settings and

Several studies have attempted to classify pragmatic trials using different definitions and scoring methods. Schwartz and Lellouch1 developed a framework to discern between explanation-based studies that confirm a physiological or clinical hypothesis, and pragmatic studies that inform the choice for appropriate therapies in clinical practice. The framework was comprised of nine domains that were scored on a scale of 1 to 5 with 1 indicating more explanatory and

The original PRECIS tool3 was based on a similar scale and domains. Koppenaal et al10 devised an adaptation of this assessment dubbed the Pragmascope that was simpler to use in systematic reviews. They discovered that pragmatic systematic reviews had higher average scores across all domains but lower scores in the primary analysis domain.
This difference in primary analysis domains could be explained by the way that most pragmatic trials approach data. Some explanatory trials, however don't. The overall score for pragmatic systematic reviews was lower when the domains of management, flexible delivery and following-up were combined.
It is important to understand that a pragmatic trial doesn't necessarily mean a low-quality trial, and in fact there is an increasing rate of clinical trials (as defined by MEDLINE search, however it is neither specific nor sensitive) that employ the term "pragmatic" in their abstracts or titles. The use of these terms in abstracts and titles could indicate a greater understanding of the importance of pragmatism but it isn't clear if this is reflected in the content of the articles.
Conclusions
In recent years, pragmatic trials have been gaining popularity in research as the importance of real-world evidence is becoming increasingly acknowledged. They are clinical trials that are randomized which compare real-world treatment options instead of experimental treatments in development. They have patients that more closely mirror the ones who are treated in routine medical care, they utilize comparators that are used in routine practice (e.g. existing drugs) and rely on participant self-report of outcomes. This method has the potential to overcome the limitations of observational studies, such as the biases associated with reliance on volunteers and the lack of availability and coding variability in national registries.
Pragmatic trials offer other advantages, including the ability to draw on existing data sources and a higher probability of detecting meaningful distinctions from traditional trials. However, they may have some limitations that limit their effectiveness and generalizability. Participation rates in some trials may be lower than anticipated due to the health-promoting effect, financial incentives or competition from other research studies. A lot of pragmatic trials are restricted by the need to recruit participants in a timely manner. Practical trials aren't always equipped with controls to ensure that the observed variations aren't due to biases during the trial.
The authors of the Pragmatic Free Trial Meta identified 48 RCTs that self-labeled themselves as pragmatic and were published up to 2022. The PRECIS-2 tool was used to determine the degree of pragmatism. It includes areas such as eligibility criteria as well as recruitment flexibility and adherence to intervention and follow-up. They discovered that 14 of the trials scored as highly or pragmatic sensible (i.e. scoring 5 or higher) in one or more of these domains and that the majority of them were single-center.
Trials that have high pragmatism scores tend to have more lenient criteria for eligibility than conventional RCTs. They also include populations from many different hospitals. The authors claim that these characteristics could make the pragmatic trials more relevant and relevant to everyday clinical practice, however they do not necessarily guarantee that a pragmatic trial is completely free of bias. The pragmatism is not a fixed characteristic the test that does not possess all the characteristics of an explanation study can still produce reliable and beneficial results.
