Pragmatic Free Trial Meta
Pragmatic Free Trial Meta is a non-commercial open data platform and infrastructure that supports research on pragmatic trials. It collects and distributes cleaned trial data, ratings, and evaluations using PRECIS-2. This allows for diverse meta-epidemiological analyses that compare treatment effect estimates across trials of different levels of pragmatism.
Background
Pragmatic trials are becoming more widely recognized as providing real-world evidence to support clinical decision-making. However, the usage of the term "pragmatic" is not uniform and its definition and evaluation requires further clarification. Pragmatic trials are designed to guide the practice of clinical medicine and policy choices, rather than confirm a physiological hypothesis or clinical hypothesis. A pragmatic trial should try to be as close as it is to actual clinical practices which include the recruitment of participants, setting up, delivery and execution of interventions, determination and analysis results, as well as primary analysis. This is a major distinction from explanatory trials (as described by Schwartz and Lellouch1), which are designed to provide more thorough confirmation of the hypothesis.
Studies that are truly pragmatic should avoid attempting to blind participants or healthcare professionals as this could lead to distortions in estimates of the effects of treatment. The pragmatic trials also include patients from various healthcare settings to ensure that the results can be generalized to the real world.
Finally, pragmatic trials must be focused on outcomes that matter to patients, such as the quality of life and functional recovery. This is especially important for trials involving surgical procedures that are invasive or have potentially serious adverse events. The CRASH trial29, for example was focused on functional outcomes to compare a two-page report with an electronic system to monitor the health of patients in hospitals suffering from chronic heart failure. In addition, the catheter trial28 used symptomatic catheter-associated urinary tract infections as the primary outcome.
In addition to these features, pragmatic trials should minimize the procedures for conducting trials and requirements for data collection to cut costs and time commitments. Finaly these trials should strive to make their findings as applicable to current clinical practice as is possible. This can be accomplished by ensuring their primary analysis is based on the intention-to treat approach (as described within CONSORT extensions).
Many RCTs that do not meet the criteria for pragmatism, but have features that are in opposition to pragmatism, have been published in journals of different types and incorrectly labeled as pragmatic. This can result in misleading claims of pragmaticity and the usage of the term should be standardized. The development of a PRECIS-2 tool that provides an objective, standardized evaluation of the pragmatic characteristics is the first step.
Methods
In a pragmatic research study, the goal is 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 relationship within idealised settings. Consequently, pragmatic trials may be less reliable than explanatory trials, and could be more susceptible to bias in their design, conduct, and analysis. Despite these limitations, pragmatic trials may be a valuable source of information for decisions in the context of healthcare.
The PRECIS-2 tool evaluates the degree of pragmatism within an RCT by scoring it across 9 domains, ranging from 1 (very explicit) to 5 (very pragmatic). In this study the areas of recruitment, organization and flexibility in delivery,

Jorgensen-Hald-3.Hubstack.Net, flexible adherence and follow-up scored high. However, the principal outcome and method of missing data were scored below the practical limit. This suggests that it is possible to design a trial with excellent pragmatic features without harming the quality of the outcomes.
It is difficult to determine the amount of pragmatism in a particular trial since pragmatism doesn't have a single characteristic. Certain aspects of a study can be more pragmatic than other. Moreover, protocol or logistic modifications during the course of an experiment can alter its score in pragmatism. Koppenaal and colleagues found that 36% of 89 pragmatic studies were placebo-controlled or conducted prior to licensing. The majority of them were single-center. They are not in line with the norm, and can only be referred to as pragmatic if their sponsors accept that the trials are not blinded.
A common feature of pragmatic studies is that researchers try to make their findings more meaningful by analyzing subgroups of the trial sample. This can result in unbalanced analyses with lower statistical power. This increases the risk of omitting or misinterpreting differences in the primary outcomes. In the case of the pragmatic trials that were included in this meta-analysis this was a significant problem since the secondary outcomes were not adjusted to account for variations in baseline covariates.
Additionally, studies that are pragmatic can present challenges in the gathering and

This is due to the fact that adverse events are generally reported by the participants themselves and are susceptible to delays in reporting, inaccuracies or coding deviations. It is important to increase the accuracy and quality of outcomes in these trials.
Results
Although the definition of pragmatism may not require that clinical trials be 100% pragmatist, there are benefits of including pragmatic elements in trials. These include:
Incorporating routine patients, the trial results can be translated more quickly into clinical practice. However, pragmatic studies can also have disadvantages. For example, the right type of heterogeneity could help a study to generalize its results to different settings and patients. However the wrong kind of heterogeneity may reduce the assay's sensitiveness and consequently reduce the power of a trial to detect even minor effects of treatment.
Several studies have attempted to classify pragmatic trials using a variety of definitions and scoring methods. Schwartz and Lellouch1 developed a framework for distinguishing between explanatory trials that confirm a clinical or physiological hypothesis, and pragmatic trials that inform the choice of appropriate therapies in the real-world clinical setting. The framework was comprised of nine domains that were assessed on a scale of 1-5 which indicated that 1 was more lucid while 5 was more pragmatic. The domains included recruitment and setting up, the delivery of intervention, flex adherence and primary analysis.
The original PRECIS tool3 was based on a similar scale and domains. Koppenaal et al10 developed an adaptation of this assessment, called the Pragmascope which was more user-friendly to use for systematic reviews. They discovered that pragmatic reviews scored higher on average in all domains, but scored lower in the primary analysis domain.
This difference in the analysis domain that is primary could be due to the fact that most pragmatic trials process their data in an intention to treat method, whereas some explanatory trials do not. The overall score for systematic reviews that were pragmatic was lower when the areas of organisation,

It is crucial to keep in mind that a pragmatic study does not necessarily mean a low-quality study.
