Pragmatic Free Trial Meta
Pragmatic Free Trail Meta is an open data platform that facilitates research into pragmatic trials. It collects and shares cleaned trial data and ratings using PRECIS-2, which allows for multiple and varied meta-epidemiological studies that examine the effects of treatment across trials with 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. The term "pragmatic" however, is a word that is often used in contradiction and its definition and assessment need further clarification. Pragmatic trials are designed to guide the practice of clinical medicine and policy choices, rather than verify a physiological hypothesis or clinical hypothesis. A pragmatic trial should aim to be as close as possible to actual clinical practices that include recruiting participants, setting up, delivery and implementation of interventions, determination and analysis outcomes, and primary analysis. This is a major distinction between explanatory trials as described by Schwartz & Lellouch1 which are designed to prove the hypothesis in a more thorough way.
Truly pragmatic trials should not blind participants or clinicians. This can lead to a bias in the estimates of the effect 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.
Finally, pragmatic trials must be focused on outcomes that matter to patients, such as the quality of life and functional recovery. This is particularly relevant for trials involving surgical procedures that are invasive or have potential for serious adverse events. The CRASH trial29, for instance was focused on functional outcomes to compare a 2-page case-report with an electronic system to monitor the health of patients admitted to hospitals with chronic heart failure, and the catheter trial28 focused on urinary tract infections that are symptomatic of catheters as the primary outcome.
In addition to these characteristics pragmatic trials should reduce the trial's procedures and data collection requirements to reduce costs. Additionally, pragmatic trials should aim to make their results as applicable to current clinical practices as they can. This can be achieved by ensuring that their analysis is based on an intention-to treat method (as described in CONSORT extensions).
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 pragmatic. This could lead to misleading claims of pragmatism and the usage of the term needs to be standardized. The creation of the PRECIS-2 tool, which provides an objective standard for assessing pragmatic features, is a good first step.
Methods
In a pragmatic research study, the goal is to inform policy or clinical decisions by demonstrating how an intervention could be integrated into routine treatment in real-world situations. Explanatory trials test hypotheses concerning the cause-effect relation within idealized settings. Therefore, pragmatic trials could have lower internal validity than explanatory trials, and could be more susceptible to bias in their design, conduct, and analysis. Despite these limitations, pragmatic trials can be a valuable source of information for decision-making in the context of healthcare.
The PRECIS-2 tool evaluates an RCT on 9 domains, with scores ranging between 1 and 5 (very pragmatist). In this study, the areas of recruitment, organisation as well as flexibility in delivery flexible adherence and follow-up scored high. However, the principal outcome and the method for missing data scored below the pragmatic limit. This suggests that it is possible to design a trial with high-quality pragmatic features, without damaging the quality of its results.
It is difficult to determine the level of pragmatism that is present in a trial since pragmatism doesn't possess a specific characteristic. Some aspects of a study can be more pragmatic than other. A trial's pragmatism could be affected by modifications to the protocol or logistics during the trial. In addition 36% of the 89 pragmatic trials identified by Koppenaal and colleagues were placebo-controlled, or conducted prior to licensing and most were single-center. They are not close to the usual practice, and can only be called pragmatic if their sponsors accept that these trials aren't blinded.
A typical feature of pragmatic research is that researchers try to make their findings more relevant by studying subgroups of the trial sample. This can lead to unbalanced results and lower statistical power, thereby increasing the risk of either not detecting or

Additionally, pragmatic trials can also 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 prone to reporting errors,

Results
While the definition of pragmatism does not require that all trials are 100 percent pragmatic, there are some advantages of including pragmatic elements in clinical trials. These include:
Increasing sensitivity to real-world issues as well as reducing study size and cost, and enabling the trial results to be more quickly transferred into real-world clinical practice (by including routine patients). However, pragmatic trials may also have drawbacks. The right type of heterogeneity, like could allow a study to expand its findings to different patients or settings. However the wrong kind of heterogeneity can reduce the assay sensitivity and thus lessen the power of a trial to detect even minor effects of treatment.
A number of studies have attempted to classify pragmatic trials with various definitions and scoring systems. Schwartz and Lellouch1 developed a framework for distinguishing between research studies that prove the clinical or physiological hypothesis as well as pragmatic trials that help in the choice of appropriate therapies in the real-world clinical setting. Their framework comprised nine domains, each scored on a scale ranging from 1-5, with 1 indicating more explanatory and 5 indicating more pragmatic. The domains were recruitment setting, setting, intervention delivery,
프라그마틱 불법 flexible adherence, follow-up and primary analysis.
The initial PRECIS tool3 had similar domains and a scale of 1 to 5. Koppenaal and colleagues10 created an adaptation of the assessment, dubbed the Pragmascope that was simpler to use for systematic reviews. They found that pragmatic systematic reviews had higher average score in most domains, with lower scores in the primary analysis domain.
The difference in the primary analysis domain could be explained by the fact that most pragmatic trials process their data in the intention to treat manner, whereas some explanatory trials do not. The overall score was lower for systematic reviews that were pragmatic when the domains on organisation, flexible delivery, and follow-up were merged.
