Pragmatic Free Trial Meta
Pragmatic Free Trail Meta is an open data platform that facilitates research into pragmatic trials. It collects and

Background
Pragmatic studies are increasingly acknowledged as providing evidence from the real world to support clinical decision-making. The term "pragmatic" however,

Pragmatic trials are designed to inform clinical practices and policy decisions rather than verify a physiological hypothesis or clinical hypothesis. A pragmatic trial should try to be as similar to real-world clinical practice as possible, such as the participation of participants, setting up and design, the delivery and execution of the intervention, determination and analysis of the outcomes, and primary analysis. This is a major difference between explanatory trials, as defined by Schwartz & Lellouch1 that are designed to test the hypothesis in a more thorough way.
Studies that are truly pragmatic must not attempt to blind participants or the clinicians, as this may lead to bias in the estimation of treatment effects. Pragmatic trials will also recruit patients from different health care settings to ensure that the results can be generalized to the real world.
Furthermore, trials that are pragmatic must be focused on outcomes that matter to patients, such as quality of life and functional recovery. This is particularly relevant for trials that involve the use of invasive procedures or could have dangerous adverse consequences. The CRASH trial29, for example, focused on functional outcomes to evaluate a two-page case report with an electronic system for monitoring of patients admitted to hospitals with chronic heart failure. Similarly, the catheter trial28 used urinary tract infections caused by catheters as its primary outcome.
In addition to these characteristics, pragmatic trials should minimize the trial's procedures and requirements for data collection to reduce costs. In the end the aim of pragmatic trials is to make their results as applicable to current clinical practices as possible. This can be achieved by ensuring that their analysis is based on an intention-to treat method (as defined in CONSORT extensions).
Despite these criteria however, a large number of RCTs with features that defy the concept of pragmatism have been mislabeled as pragmatic and published in journals of all kinds. This can lead to misleading claims of pragmatism, and the term's use should be made more uniform. The development of the PRECIS-2 tool, which offers a standard objective assessment of pragmatic features is a great first step.
Methods
In a pragmatic trial it is the intention to inform clinical or policy decisions by showing how an intervention could be integrated into everyday routine care. This is distinct from explanation trials, which test hypotheses about the cause-effect relationship in idealised settings. Therefore, 프라그마틱 슬롯 하는법 -

The PRECIS-2 tool scores an RCT on 9 domains, ranging from 1 to 5 (very pragmatic). In this study the areas of recruitment, organization, flexibility in delivery, flexible adherence, and follow-up scored high. However, the primary outcome and the method of missing data was scored below the pragmatic limit. This suggests that it is possible to design a trial using excellent pragmatic features without harming the quality of the outcomes.
It is, however, difficult to determine how pragmatic a particular trial is since the pragmatism score is not a binary quality; certain aspects of a trial can be more pragmatic than others. Additionally, logistical or protocol changes during a trial can change its score on pragmatism. Koppenaal and colleagues found that 36% of the 89 pragmatic studies were placebo-controlled or conducted prior to the licensing. They also found that the majority were single-center. Thus, they are not quite as typical and are only pragmatic when their sponsors are accepting of the lack of blinding in these trials.
A typical feature of pragmatic studies is that researchers try to make their findings more meaningful by studying subgroups within the trial. However, this often leads to unbalanced comparisons and lower statistical power, increasing the chance of not or misinterpreting the results of the primary outcome. In the instance of the pragmatic trials included in this meta-analysis this was a major issue because the secondary outcomes were not adjusted for differences in baseline covariates.
Additionally practical trials can have challenges with respect to 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 delays in reporting, inaccuracies, or coding variations. It is crucial to improve the accuracy and quality of the results in these trials.
Results
Although the definition of pragmatism may not require that all clinical trials be 100% pragmatist There are advantages when incorporating pragmatic components into trials. These include:
By including routine patients, the results of the trial can be translated more quickly into clinical practice. However, pragmatic trials may be a challenge. The right kind of heterogeneity, like, can help a study extend its findings to different settings or patients. However, the wrong type can reduce the sensitivity of an assay, and therefore 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 to discern between explanation-based studies that support the physiological hypothesis or clinical hypothesis and pragmatic studies that inform the selection of appropriate therapies in clinical practice. The framework was comprised of nine domains that were scored on a scale ranging from 1 to 5, with 1 indicating more lucid and 5 suggesting more pragmatic. The domains covered recruitment, setting up, delivery of intervention, flex adherence 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 developed an adaptation to this assessment called the Pragmascope that was easier to use in systematic reviews. They found that pragmatic systematic reviews had a higher average score in most domains, but lower scores in the primary analysis domain.
This distinction in the main analysis domain could be due to the fact that the majority of pragmatic trials analyse their data in an intention to treat manner however some explanation trials do not. The overall score for pragmatic systematic reviews was lower when the areas of management,

It is crucial to keep in mind that a pragmatic study does not necessarily mean a low-quality study. In fact, there is a growing number of clinical trials that use the term 'pragmatic' either in their title or abstract (as defined by MEDLINE however it is neither precise nor sensitive).
