Pragmatic Free Trial Meta
Pragmatic Free Trail Meta is an open data platform that enables research into pragmatic trials. It collects and shares cleaned trial data and ratings using PRECIS-2 permitting multiple and varied meta-epidemiological research studies to evaluate the effect of treatment on trials that have different levels of pragmatism, as well as other design features.
Background
Pragmatic studies provide real-world evidence that can be used to make clinical decisions. However, the usage of the term "pragmatic" is not uniform and its definition and assessment requires further clarification. Pragmatic trials must be designed to inform policy and clinical practice decisions, not to confirm a physiological or clinical hypothesis. A pragmatic trial should aim to be as close as it is to actual clinical practices, including recruiting participants, setting up, delivery and implementation of interventions, determining and analysis outcomes, and

Trials that are truly pragmatic should not attempt to blind participants or healthcare professionals as this could lead to bias in estimates of the effects of treatment. Practical trials should also aim to recruit patients from a variety of health care settings so that their results can be compared to the real world.
Furthermore the focus of pragmatic trials should be on outcomes that are vital to patients, like quality of life or functional recovery. This is particularly important when it comes to trials that involve invasive procedures or those with potential for dangerous adverse events. The CRASH trial29 compared a 2 page report with an electronic monitoring system for hospitalized patients with chronic cardiac failure. The catheter trial28, however, used symptomatic catheter associated urinary tract infection as its primary outcome.
In addition to these features, pragmatic trials should minimize trial procedures and data-collection requirements to cut costs and time commitments. Furthermore, pragmatic trials should seek to make their results as relevant to actual clinical practice as possible by making sure that their primary method of analysis is based on the intention-to-treat method (as described in CONSORT extensions for

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 could lead to misleading claims of pragmaticity and the use of the term needs to be standardized. The creation of the PRECIS-2 tool, which offers an objective and standard assessment of pragmatic features is a great first step.
Methods
In a pragmatic study, the goal is to inform clinical or policy decisions by demonstrating how an intervention can be integrated into routine treatment in real-world situations. This differs from explanation trials that test hypotheses regarding the cause-effect connection in idealized situations. Consequently, pragmatic trials may have lower internal validity than explanatory trials and may be more susceptible to bias in their design, conduct, and analysis. Despite their limitations, pragmatic research can provide valuable information for decision-making within the healthcare context.
The PRECIS-2 tool scores an RCT on 9 domains, with scores ranging from 1 to 5 (very pragmatist). In this study, the domains of recruitment, organisation, flexibility in delivery, flexible adherence, and follow-up were awarded high scores. However, the primary outcome and the method for missing data scored below the pragmatic limit. This suggests that a trial could be designed with good pragmatic features, without compromising its quality.
However, it's difficult to determine how pragmatic a particular trial is, since the pragmatism score is not a binary characteristic; certain aspects of a trial can be more pragmatic than others. The pragmatism of a trial can be affected by changes to the protocol or logistics during the trial. Additionally 36% of 89 pragmatic trials identified by Koppenaal and co. were placebo-controlled, or conducted prior to licensing and most were single-center. Thus, they are not quite as typical and can only be called pragmatic when their sponsors are accepting of the lack of blinding in these trials.
A common feature of pragmatic studies is that researchers try to make their findings more meaningful by studying subgroups of the trial sample. This can lead to unbalanced analyses that have less statistical power. This increases the risk of missing or misdetecting differences in the primary outcomes. This was a problem in the meta-analysis of pragmatic trials because secondary outcomes were not corrected for covariates that differed at baseline.
In addition, pragmatic studies may pose challenges to collection and

Therefore, it is crucial to improve the quality of outcome ascertainment in these trials, and ideally by using national registries instead of relying on participants to report adverse events on the trial's own database.
Results
Although the definition of pragmatism does not mean that trials must be 100 100% pragmatic, there are some advantages to incorporating pragmatic components into clinical trials. These include:
By including routine patients, the results of the trial can be more quickly translated into clinical practice. But pragmatic trials can be a challenge. The right amount of heterogeneity, like could help a study generalise its findings to many different settings or patients. However the wrong type of heterogeneity could reduce the sensitivity of an assay and thus decrease the ability of a study to detect minor treatment effects.
Many studies have attempted categorize pragmatic trials using various definitions and scoring methods. Schwartz and Lellouch1 developed a framework to distinguish between research studies that prove the clinical or physiological hypothesis, and pragmatic trials that inform the selection of appropriate treatments in real-world clinical practice. The framework was comprised of nine domains, each scoring on a scale of 1-5, with 1 indicating more lucid and 5 indicating more pragmatic. The domains included recruitment and setting, delivery of intervention, flexible adherence, 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 and colleagues10 created an adaptation of the assessment, known as the Pragmascope which was more user-friendly 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 distinction in the analysis domain that is primary could be due to the fact that the majority of pragmatic trials analyze their data in the intention to treat manner while some explanation trials do not. The overall score for pragmatic systematic reviews was lower when the areas of organisation, flexible delivery and follow-up were merged.
It is important to remember that a pragmatic trial does not necessarily mean a low quality trial, and indeed there is an increasing rate of clinical trials (as defined by MEDLINE search, however this is not specific nor sensitive) that use the term 'pragmatic' in their abstract or title.
