Pragmatic Free Trial Meta
Pragmatic Free Trial Meta is a non-commercial, open data platform and infrastructure that facilitates research on pragmatic trials. It collects and shares cleaned trial data and ratings using PRECIS-2, which allows for multiple and varied meta-epidemiological research studies to compare treatment effects estimates across trials that have different levels of pragmatism as well as other design features.
Background
Pragmatic trials are increasingly acknowledged as providing evidence from the real world for clinical decision making. The term "pragmatic" however, is not used in a consistent manner and its definition and measurement require further clarification. Pragmatic trials should be designed to inform clinical practice and policy decisions, not to confirm an hypothesis that is based on a clinical or physiological basis. A pragmatic study should strive to be as close as it is to the real-world clinical practice, including recruiting participants, setting, designing, delivery and implementation of interventions, determination and analysis results, as well as primary analyses. This is a major distinction between explanatory trials as defined by Schwartz and Lellouch1, which are designed to test a hypothesis in a more thorough manner.
Trials that are truly pragmatic should be careful not to blind patients or clinicians as this could result in bias in the estimation of treatment effects. Practical trials also involve patients from different health care settings to ensure that the results can be applied to the real world.
Finally, pragmatic trials should focus on outcomes that are vital for patients, such as quality of life or functional recovery. This is especially important in trials that involve invasive procedures or those with potentially serious adverse events. The CRASH trial29, for instance, focused on functional outcomes to compare a two-page report with an electronic system to monitor

In addition to these characteristics pragmatic trials should reduce trial procedures and data-collection requirements to cut costs and time commitments. Additionally pragmatic trials should strive to make their findings as applicable to clinical practice as possible by ensuring that their primary analysis is the intention-to-treat approach (as described in CONSORT extensions for pragmatic trials).
Despite these guidelines, many RCTs with features that challenge the notion of pragmatism were incorrectly labeled pragmatic and published in journals of all types. This could lead to misleading claims of pragmaticity, and the usage of the term must be standardized. The creation of a PRECIS-2 tool that provides an objective and standardized assessment of pragmatic features is a first step.
Methods
In a practical trial the goal is to inform policy or clinical decisions by showing how an intervention could be incorporated into real-world routine care. Explanatory trials test hypotheses concerning the cause-effect relation within idealized settings. In this way, pragmatic trials may have a lower internal validity than explanatory studies and be more susceptible to biases in their design as well as analysis and conduct. Despite these limitations, pragmatic trials can provide valuable information to decision-making in healthcare.
The PRECIS-2 tool evaluates an RCT on 9 domains, with scores ranging between 1 and 5 (very pragmatist). In this study, the recruit-ment, organization, flexibility in delivery and follow-up domains received high scores, however, the primary outcome and the procedure for missing data fell below the limit of practicality. This suggests that a trial could be designed with well-thought-out pragmatic features, without damaging the quality.
It is difficult to determine the amount of pragmatism within a specific trial because pragmatism does not possess a specific characteristic. Some aspects of a study can be more pragmatic than others. Additionally, logistical or protocol modifications made during a trial can change its pragmatism score. Koppenaal and colleagues found that 36% of 89 pragmatic studies were placebo-controlled or conducted prior to the licensing. Most were also single-center. They are not close to the norm and are only called pragmatic if the sponsors agree that such trials are not blinded.
Another common aspect of pragmatic trials is that researchers attempt to make their findings more valuable by studying subgroups of the trial sample. This can lead to imbalanced analyses and lower statistical power. This increases the risk of omitting or misinterpreting differences in the primary outcomes. This was a problem during the meta-analysis of pragmatic trials because secondary outcomes were not corrected for covariates that differed at baseline.
Additionally practical trials can present challenges in the collection and interpretation of safety data. This is due to the fact that adverse events are typically reported by participants themselves and are susceptible to reporting errors, delays, or coding variations. Therefore, it is crucial to improve the quality of outcome assessment in these trials, and ideally by using national registries instead of relying on participants to report adverse events on the trial's database.
Results
Although the definition of pragmatism does not mean that trials must be 100% pragmatic, there are some advantages of including pragmatic elements in clinical trials. These include:
Increasing sensitivity to real-world issues which reduces study size and cost and allowing the study results to be more quickly implemented into clinical practice (by including patients from routine care). However, pragmatic trials may also have drawbacks. The right type of heterogeneity, like could help a study generalise its findings to many different patients or settings. However, the wrong type can reduce the sensitivity of an assay and, consequently, lessen the power of a trial to detect even minor effects of treatment.
Numerous studies have attempted to categorize pragmatic trials with a variety of definitions and scoring systems. Schwartz and Lellouch1 have developed a framework for distinguishing between explanatory trials that confirm a physiological or clinical hypothesis and pragmatic trials that help in the selection of appropriate treatments in clinical practice. The framework was composed of nine domains that were scored on a 1-5 scale, with 1 being more informative and 5 was more practical. The domains included recruitment setting, setting, intervention delivery, flexible adherence, follow-up and primary analysis.
The original PRECIS tool3 was based on a similar scale and domains. Koppenaal et al10 created an adaptation of this assessment dubbed the Pragmascope that was easier to use in systematic reviews. They discovered that pragmatic reviews scored higher in all domains, but scored lower in the primary analysis domain.
This distinction in the primary analysis domain can be due to the way in which most pragmatic trials analyze data. Certain explanatory trials however, do not. The overall score was lower for pragmatic systematic reviews when the domains on the organization, flexibility of delivery and follow-up were combined.
It is crucial to keep in mind that a pragmatic study does not mean that a trial is of poor quality. In fact, there are an increasing number of clinical trials that employ the term "pragmatic" either in their title or abstract (as defined by MEDLINE but which is neither precise nor sensitive). These terms may signal a greater understanding of pragmatism in titles and abstracts, but it's unclear whether this is reflected in content.
Conclusions
As the value of evidence from the real world becomes more popular the pragmatic trial has gained popularity in research. They are clinical trials randomized that compare real-world care alternatives rather than experimental treatments under development, they involve populations of patients which are more closely resembling the ones who are treated in routine medical care, they utilize comparisons that are commonplace in practice (e.g. existing drugs) and depend on the self-reporting of participants about outcomes. This method is able to overcome the limitations of observational research for example, the biases that are associated with the reliance on volunteers and the lack of the coding differences in national registry.
Pragmatic trials also have advantages,

However, these trials could be prone to limitations that compromise their validity and generalizability. The participation rates in certain trials could be lower than anticipated because of the healthy-volunteering effect, financial incentives or competition from other research studies. Many pragmatic trials are also limited by the need to enroll participants in a timely manner. In addition, 프라그마틱 정품 확인법 -

The authors of the Pragmatic Free Trial Meta identified 48 RCTs that self-described themselves as pragmatic and that were published until 2022. The PRECIS-2 tool was used to determine the degree of pragmatism. It covers areas like eligibility criteria and flexibility in recruitment as well as adherence to interventions and follow-up. They discovered 14 trials scored highly pragmatic or pragmatic (i.e. scoring 5 or above) in at least one of these domains.
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 applicable in the daily clinical. However, they don't guarantee that a trial will be free of bias. The pragmatism is not a fixed attribute and a test that doesn't have all the characteristics of an explanatory study can still produce valid and useful outcomes.
