Pragmatic Free Trial Meta
Pragmatic Free Trail Meta is an open data platform that allows research into pragmatic trials. It collects and distributes clean trial data, ratings, and evaluations using PRECIS-2. This allows for diverse meta-epidemiological studies to examine the effect of treatment across trials of different levels of pragmatism.
Background
Pragmatic trials provide evidence from the real world that can be used to make clinical decisions. However, the use of the term "pragmatic" is inconsistent and its definition and evaluation requires further clarification. Pragmatic trials must be designed to guide clinical practice and policy decisions, rather than confirm the validity of a clinical or physiological hypothesis. A pragmatic trial should aim to be as close as possible to real-world clinical practices that include recruiting participants, setting, designing, implementation and delivery of interventions, determining and analysis outcomes,

Truly pragmatic trials should not be blind participants or clinicians. This could lead to bias in the estimations of the effects of treatment. The trials that are pragmatic should also try to enroll patients from a variety of health care settings, so that their results can be compared to the real world.
Additionally, pragmatic trials should focus on outcomes that are important to patients, like quality of life or functional recovery. This is especially important when trials involve surgical procedures that are invasive or may have dangerous adverse consequences. The CRASH trial29 compared a 2-page report with an electronic monitoring system for patients in hospitals suffering from chronic cardiac failure. The catheter trial28, on the other hand, used symptomatic catheter associated urinary tract infections as its primary outcome.
In addition to these features, pragmatic trials should minimize the trial procedures and data collection requirements in order to reduce costs. Furthermore pragmatic trials should try to make their findings as applicable to clinical practice as is possible by ensuring that their primary analysis follows the intention-to treat approach (as described in CONSORT extensions for pragmatic trials).
Many RCTs that do not meet the criteria for pragmatism but have features that are contrary to pragmatism, have been published in journals of varying types and incorrectly labeled as pragmatic. This can lead to false claims of pragmaticity and the usage of the term must be standardized. The creation of a PRECIS-2 tool that offers a standardized objective assessment of pragmatic features is the first step.
Methods
In a pragmatic research study the aim is to inform policy or clinical decisions by showing how an intervention could be integrated into routine treatment in real-world contexts. This is different from explanatory trials that test hypotheses regarding the cause-effect relationship in idealised conditions. In this way, pragmatic trials may have less internal validity than studies that explain and be more susceptible to biases in their design analysis, conduct, and design. Despite these limitations, pragmatic trials can provide valuable information to decision-making in healthcare.
The PRECIS-2 tool assesses the level of pragmatism that is present in an RCT by scoring it across 9 domains ranging from 1 (very explicit) to 5 (very pragmatic). In this study, the recruit-ment organisation, flexibility: delivery and follow-up domains received high scores, but the primary outcome and the method for missing data were not at the pragmatic limit. This suggests that a trial could be designed with effective practical features, but without damaging the quality.
It is, however, difficult to assess how practical a particular trial is since pragmaticity is not a definite attribute; some aspects of a trial may be more pragmatic than others. The pragmatism of a trial can be affected by changes to the protocol or the 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. They aren't in line with the usual practice and can only be referred to as pragmatic if the sponsors agree that these trials aren't blinded.
A common feature of pragmatic research is that researchers try to make their findings more meaningful by analyzing subgroups of the trial sample. This can lead to imbalanced analyses and lower statistical power. This increases the possibility of omitting or ignoring differences in the primary outcomes. This was a problem during the meta-analysis of pragmatic trials as secondary outcomes were not adjusted for covariates' differences at baseline.
Additionally, studies that are pragmatic may pose challenges to gathering and interpretation of safety data. This is due to the fact that adverse events are usually self-reported and

It is therefore crucial to improve the quality of outcome assessment in these trials, in particular by using national registry databases instead of relying on participants to report adverse events on a trial's own database.
Results
While the definition of pragmatism does not require that all clinical trials are 100% pragmatic there are benefits when incorporating pragmatic components into trials. These include:
By incorporating routine patients, the results of trials can be more quickly translated into clinical practice. However, pragmatic trials may have disadvantages. For instance, the right type of heterogeneity could help a study to generalize its findings to a variety of settings and patients. However, the wrong type of heterogeneity can reduce assay sensitivity, and thus lessen the ability of a study to detect minor treatment effects.
A variety of studies have attempted to categorize pragmatic trials using various definitions and scoring systems. Schwartz and Lellouch1 created a framework for distinguishing between explanation-based trials that support the clinical or physiological hypothesis and pragmatic trials that help in the selection of appropriate treatments in real-world clinical practice. The framework was composed of nine domains that were evaluated on a scale of 1-5 which indicated that 1 was more lucid while 5 was more practical. The domains included recruitment and setting, delivery of intervention with flexibility, follow-up and primary analysis.
The initial PRECIS tool3 featured similar domains and scales from 1 to 5. Koppenaal et al10 developed an adaptation of this assessment, called the Pragmascope that was simpler to use for systematic reviews. They discovered that pragmatic systematic reviews had a higher average scores across all domains, but lower scores in the primary analysis domain.
This difference in primary analysis domains can be due to the way in which most pragmatic trials approach data. Some explanatory trials, however don't. The overall score was lower for systematic reviews that were pragmatic when the domains on organisation, flexible delivery, and follow-up were merged.
It is important to remember that a study that is pragmatic does not necessarily mean a low-quality study. In fact, there is an increasing number of clinical trials that employ the term 'pragmatic' either in their abstracts or titles (as defined by MEDLINE but which is neither sensitive nor precise).
