Pragmatic Free Trial Meta
Pragmatic Free Trail Meta is an open data platform that facilitates research into pragmatic trials. It collects and distributes clean trial data, ratings and evaluations using PRECIS-2. This permits a variety of meta-epidemiological analyses to compare treatment effect estimates across trials of various levels of pragmatism.
Background
Pragmatic trials are becoming more widely recognized as providing real-world evidence for clinical decision making. However, the usage of the term "pragmatic" is not uniform and its definition and evaluation requires clarification. The purpose of pragmatic trials is to inform policy and clinical practice decisions, rather than to prove the validity of a clinical or physiological hypothesis. A pragmatic trial should aim to be as close as possible to real-world clinical practices which include the recruitment of participants, setting,

writes in the official Leftbookmarks blog) designing, delivery and implementation of interventions, determination and analysis results, as well as primary analysis. This is a major difference between explanatory trials, as described by Schwartz & Lellouch1, which are designed to prove a hypothesis in a more thorough way.
Truely pragmatic trials should not be blind participants or clinicians. This could lead to a bias in the estimates of the effect of treatment. Practical trials also involve patients from various healthcare settings to ensure that their results can be generalized to the real world.
Finally, pragmatic trials must concentrate on outcomes that are important to patients, like quality of life and functional recovery. This is particularly important when trials involve the use of invasive procedures or could have harmful adverse consequences. The CRASH trial29, for example was focused on functional outcomes to compare a 2-page case-report with an electronic system for monitoring of patients in hospitals suffering from chronic heart failure, and the catheter trial28 used urinary tract infections that are symptomatic of catheters as its primary outcome.
In addition to these features pragmatic trials should also reduce the procedures for conducting trials and requirements for data collection to reduce costs and time commitments. Finally, pragmatic trials should seek to make their findings as applicable to clinical practice as they can by ensuring that their primary analysis follows the intention-to treat approach (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 different 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 development of the PRECIS-2 tool, which offers an objective and standard assessment of pragmatic features, is a good first step.
Methods
In a pragmatic research study the aim is to inform policy or clinical decisions by demonstrating how an intervention can be integrated into routine care in real-world settings. Explanatory trials test hypotheses regarding the cause-effect relationship within idealised conditions. In this way, pragmatic trials can have a lower internal validity than studies that explain and be more susceptible to biases in their design analysis, conduct, and design. Despite their limitations, pragmatic studies can be a valuable source of information for decision-making within the context of healthcare.
The PRECIS-2 tool measures the level of pragmatism that is present in an RCT by scoring it across 9 domains that range from 1 (very explicit) to 5 (very pragmatic). In this study, the areas of recruitment, organisation as well as flexibility in delivery flexibility in adherence, and

However, it's difficult to assess the degree of pragmatism a trial really is because pragmaticity is not a definite attribute; some aspects of a trial can be more pragmatic than others. Furthermore, logistical or protocol modifications made during the trial may alter its pragmatism score. In addition, 36% of the 89 pragmatic trials discovered by Koppenaal and co. were placebo-controlled or conducted prior to approval and a majority of them were single-center. They are not close to the standard practice, and can only be considered pragmatic if their sponsors accept that the trials are not blinded.
A typical feature of pragmatic studies is that researchers try to make their findings more meaningful by analyzing subgroups within the trial. However, this often leads to unbalanced results and lower statistical power, increasing the likelihood of missing or misinterpreting differences in the primary outcome. This was a problem during the meta-analysis of pragmatic trials due to the fact that secondary outcomes were not adjusted for covariates that differed at the time of baseline.
Furthermore, pragmatic studies can present challenges in the collection and interpretation safety data. This is due to the fact that adverse events are typically reported by participants themselves and are prone to delays in reporting, inaccuracies, or coding variations. It is essential to improve the quality and accuracy of the results in these trials.
Results
Although the definition of pragmatism may not require that all trials be 100 percent pragmatic, there are some advantages to including pragmatic components in clinical trials. These include:
Increased sensitivity to real-world issues, reducing the size of studies and their costs as well as allowing trial results to be more quickly translated into actual clinical practice (by including patients from routine care). However, pragmatic studies can also have disadvantages. The right amount of heterogeneity, like could allow a study to generalise its findings to many different patients or settings. However the wrong type of heterogeneity could reduce the assay sensitivity and thus reduce a trial's power to detect minor treatment effects.
Many studies have attempted categorize pragmatic trials using various definitions and scoring methods. Schwartz and Lellouch1 have developed a framework that can differentiate between explanation studies that confirm a physiological hypothesis or clinical hypothesis, and pragmatic studies that help inform the selection of appropriate therapies in the real-world clinical practice. The framework was comprised of nine domains that were evaluated on a scale of 1-5 with 1 being more explanatory while 5 was more pragmatic. The domains were recruitment, setting, intervention delivery with flexibility, follow-up and primary analysis.
The original PRECIS tool3 was an adapted version of the PRECIS tool3 that was based on the same scale and domains. 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 reviews scored higher across all domains, however they scored lower in the primary analysis domain.
This difference in primary analysis domain can be explained by the way most pragmatic trials analyse data. Some explanatory trials, however do not. The overall score was lower for pragmatic systematic reviews when the domains of organisation, flexible delivery, and follow-up were merged.
It is important to remember that a pragmatic study does not necessarily mean a low-quality study. In fact, there are a growing number of clinical trials that use the term 'pragmatic' either in their title or abstract (as defined by MEDLINE but which is neither sensitive nor precise). 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
As the importance of evidence from the real world becomes more commonplace the pragmatic trial has gained momentum in research. They are randomized trials that evaluate real-world care alternatives to clinical trials in development. They are conducted with populations of patients more closely resembling those treated in regular medical care. This method could help overcome the limitations of observational research which include the biases that arise from relying on volunteers and the lack of accessibility and coding flexibility in national registry systems.
Other benefits of pragmatic trials include the possibility of using existing data sources, as well as a higher likelihood of detecting meaningful changes than traditional trials. However, these trials could have some limitations that limit their reliability and generalizability. For example the participation rates in certain trials might be lower than expected due to the healthy-volunteer influence and incentives to pay or compete for participants from other research studies (e.g., industry trials). The need to recruit individuals in a timely fashion also restricts the sample size and the impact of many practical trials. Additionally, some pragmatic trials do not have controls to ensure that the observed differences are not due to biases in the conduct of trials.
The authors of the Pragmatic Free Trial Meta identified RCTs published from 2022 to 2022 that self-described as pragmatism. The PRECIS-2 tool was used to evaluate the degree of pragmatism. It covers domains such as eligibility criteria and flexibility in recruitment, adherence to intervention, and follow-up. They discovered that 14 of these trials scored pragmatic or highly sensible (i.e. scoring 5 or higher) in one or more of these domains and that the majority were single-center.
Trials with a high pragmatism score tend to have more expansive eligibility criteria than traditional RCTs that have specific criteria that are unlikely to be used in clinical practice, and they comprise patients from a wide variety of hospitals. The authors argue that these characteristics could make the pragmatic trials more relevant and relevant to daily practice, but they do not guarantee that a trial using a pragmatic approach is completely free of bias. Furthermore, the pragmatism of trials is not a fixed attribute A pragmatic trial that does not possess all the characteristics of an explanatory trial can yield valuable and reliable results.
