Pragmatic Free Trial Meta
Pragmatic Free Trail Meta is an open data platform that enables research into pragmatic trials. It collects and distributes clean trial data, ratings, and evaluations using PRECIS-2. This allows for diverse meta-epidemiological analyses that compare treatment effect estimates across trials of various levels of pragmatism.
Background
Pragmatic studies are increasingly acknowledged as providing evidence from the real world to support clinical decision-making. However, the usage of the term "pragmatic" is not consistent and its definition as well as assessment requires further clarification. Pragmatic trials should be designed to inform policy and clinical practice decisions, rather than to prove the validity of a clinical or physiological hypothesis. A pragmatic trial should also try to be as similar to actual clinical practice as possible, such as the selection of participants, setting up and design, the delivery and execution of the intervention, and the determination and analysis of the outcomes, and primary analysis. This is a major difference from explanatory trials (as described by Schwartz and Lellouch1), which are designed to provide more thorough confirmation of a hypothesis.
Truely pragmatic trials should not blind participants or clinicians. This could lead to an overestimation of treatment effects. Pragmatic trials should also seek to attract patients from a variety of health care settings to ensure that their findings can be applied to the real world.
Additionally, pragmatic trials should focus on outcomes that are vital to patients, such as quality of life or functional recovery. This is particularly relevant for trials that involve surgical procedures that are invasive or may have harmful adverse consequences. The CRASH trial29 compared a 2-page report with an electronic monitoring system for hospitalized patients suffering from chronic cardiac failure. The trial with a catheter, however was based on symptomatic catheter-related urinary tract infections as its primary outcome.
In addition to these characteristics the pragmatic trial should also reduce the trial's procedures and data collection requirements in order to reduce costs. Finally pragmatic trials should strive to make their results as relevant to actual clinical practice as they can by making sure that their primary method of analysis is the intention-to-treat approach (as described in CONSORT extensions for pragmatic trials).
Despite these criteria however, a large number of RCTs with features that challenge the notion of pragmatism were incorrectly labeled pragmatic and published in journals of all types. This can lead to false claims of pragmatism and the usage of the term needs to be standardized. The development of a PRECIS-2 tool that can provide an objective, standardized assessment of pragmatic features is a good start.
Methods
In a pragmatic study the aim is to inform clinical or policy decisions by demonstrating how an intervention could be integrated into routine care in real-world settings. This is distinct from explanation trials, which test hypotheses about the causal-effect relationship in idealized situations. Therefore, pragmatic trials could be less reliable than explanatory trials, and could be more susceptible to bias in their design, conduct, and analysis. Despite these limitations, pragmatic trials can provide valuable information to decision-making in healthcare.
The PRECIS-2 tool evaluates an RCT on 9 domains, ranging from 1 to 5 (very pragmatist). In this study the areas of recruitment, organization, flexibility in delivery, flexible adherence and follow-up scored high. However, the main outcome and

It is hard to determine the level of pragmatism in a particular trial since pragmatism doesn't possess a specific attribute. Certain aspects of a study may be more pragmatic than other. A trial's pragmatism could be affected by changes to the protocol or logistics during the trial. Koppenaal and colleagues found that 36% of 89 pragmatic studies were placebo-controlled, or conducted prior to the licensing. The majority of them were single-center. Therefore,

Another common aspect of pragmatic trials is that the researchers attempt to make their findings more relevant by analyzing subgroups of the trial. This can result in unbalanced analyses that have lower statistical power. This increases the possibility of omitting or ignoring differences in the primary outcomes. This was the case in the meta-analysis of pragmatic trials because secondary outcomes were not adjusted for covariates that differed at the baseline.
Furthermore the pragmatic trials may have challenges with respect to the gathering and interpretation of safety data. This is due to the fact that adverse events are usually self-reported and are susceptible to reporting errors, delays, or coding variations. It is essential to increase the accuracy and quality of the results in these trials.
Results
While the definition of pragmatism may not require that all clinical trials are 100% pragmatic there are benefits to including pragmatic components in trials. These include:
Incorporating routine patients, the results of the trial can be translated more quickly into clinical practice. However, pragmatic studies can also have drawbacks. The right amount of heterogeneity, like, can help a study expand its findings to different settings or patients. However, the wrong type can decrease the sensitivity of the test and, consequently, reduce a trial's power to detect even minor effects of treatment.
A variety of studies have attempted to categorize pragmatic trials using various definitions and scoring methods. Schwartz and Lellouch1 developed a framework to discern between explanation-based studies that prove a physiological hypothesis or clinical hypothesis and pragmatic studies that guide the selection of appropriate therapies in the real-world clinical practice. The framework was composed of nine domains that were scored on a 1-5 scale, with 1 being more informative and 5 being more pragmatic. The domains covered recruitment of intervention, setting up, delivery of intervention, flex adherence 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 and colleagues10 developed an adaptation of this assessment dubbed the Pragmascope that was simpler to use in systematic reviews. They found that pragmatic systematic reviews had higher average scores across all domains but lower scores in the primary analysis domain.
This distinction in the main analysis domain could be explained by the fact that most pragmatic trials analyze their data in the intention to treat method while some explanation trials do not. The overall score was lower for systematic reviews that were pragmatic when the domains on the organization, flexibility of delivery and follow-up were merged.
It is important to note that a pragmatic trial doesn't necessarily mean a poor quality trial, and indeed there is an increasing number of clinical trials (as defined by MEDLINE search, but this is neither specific or sensitive) which use the word 'pragmatic' in their abstract or title. The use of these terms in abstracts and titles may suggest a greater awareness of the importance of pragmatism, but it is unclear whether this is reflected in the content of the articles.
Conclusions
As appreciation for the value of real-world evidence becomes increasingly widespread, pragmatic trials have gained popularity in research. They are clinical trials randomized that compare real-world care alternatives instead of experimental treatments in development. They involve patient populations that are more similar to the ones who are treated in routine care, they use comparators which exist in routine practice (e.g. existing medications) and depend on the self-reporting of participants about outcomes. This approach has the potential to overcome the limitations of observational research which include the biases associated with reliance on volunteers and the lack of availability and the variability of coding in national registry systems.
Pragmatic trials also have advantages, including the ability to leverage existing data sources, and a greater likelihood of detecting meaningful distinctions from traditional trials. However, pragmatic trials may be prone to limitations that compromise their reliability and generalizability. For instance the participation rates in certain trials might be lower than expected due to the healthy-volunteer effect as well as incentives to pay or compete for

The need to recruit individuals in a timely manner also reduces the size of the sample and the impact of many practical trials. Some pragmatic trials also lack controls to ensure that observed differences aren't caused by biases during the trial.
The authors of the Pragmatic Free Trial Meta identified 48 RCTs that self-labeled themselves as pragmatic and were published until 2022. The PRECIS-2 tool was used to assess the pragmatism of these trials. It includes areas like eligibility criteria, recruitment flexibility and adherence to intervention and follow-up. They discovered that 14 of the trials scored as highly or pragmatic practical (i.e. scoring 5 or higher) in any one or more of these domains and that the majority were single-center.
Trials that have a high pragmatism score tend to have broader eligibility criteria than traditional RCTs, which include very specific criteria that aren't likely to be present in the clinical environment, and they include populations from a wide range of hospitals. The authors argue that these characteristics could make pragmatic trials more effective and useful for everyday practice, but they do not necessarily guarantee that a trial using a pragmatic approach is free from bias. Moreover, the pragmatism of a trial is not a fixed attribute and a pragmatic trial that does not have all the characteristics of an explanatory trial may yield valuable and reliable results.
