Pragmatic Free Trial Meta
Pragmatic Free Trial Meta is a non-commercial open data platform and infrastructure that supports research on pragmatic trials. It gathers and distributes clean trial data, ratings, and evaluations using PRECIS-2. This allows for diverse meta-epidemiological analyses to evaluate the effects of treatment across trials of different levels of pragmatism.
Background
Pragmatic studies are increasingly recognized as providing real-world evidence for clinical decision making. However, the usage of the term "pragmatic" is not consistent and its definition and assessment requires further clarification. Pragmatic trials are intended to inform clinical practices and policy decisions, not to confirm a physiological hypothesis or clinical hypothesis. A pragmatic study should strive to be as close as is possible to real-world clinical practices, including recruitment of participants, setting, designing, delivery and implementation of interventions, determining and analysis results, as well as primary analyses. This is a significant difference between explanatory trials, as described by Schwartz & Lellouch1 which are designed to confirm a hypothesis in a more thorough manner.
Studies that are truly pragmatic should not attempt to blind participants or the clinicians, as this may result in bias in estimates of treatment effects. Practical trials also involve patients from different healthcare settings to ensure that their results can be generalized to the real world.
Finally, pragmatic trials must focus on outcomes that matter to patients, like quality of life and functional recovery. This is especially important for trials that involve surgical procedures that are invasive or may have harmful adverse effects. The CRASH trial29, for example was focused on functional outcomes to compare a 2-page case-report with an electronic system to monitor the health of patients in hospitals suffering from chronic heart failure. In addition, the catheter trial28 used urinary tract infections caused by catheters as its primary outcome.
In addition to these aspects pragmatic trials should reduce the trial procedures and data collection requirements to reduce costs. Additionally pragmatic trials should try to make their findings as applicable to clinical practice as possible by making sure that their primary analysis follows the intention-to treat approach (as described in CONSORT extensions for pragmatic trials).
Despite these guidelines, many RCTs with features that defy the concept of pragmatism have been mislabeled as pragmatic and published in journals of all kinds. This could lead to misleading claims of pragmatism, and the usage of the term should be standardized. The creation of a PRECIS-2 tool that can provide a standardized objective evaluation of pragmatic aspects is the first step.
Methods
In a pragmatic study the goal is to inform clinical or policy decisions by demonstrating how an intervention would be integrated into everyday routine care. Explanatory trials test hypotheses about the causal-effect relationship in idealized settings. Consequently, pragmatic trials may be less reliable than explanatory trials and might be more susceptible to bias in their destrial sample. This can result in imbalanced analyses and lower statistical power. This increases the chance of omitting or 프라그마틱 정품확인방법 ignoring differences in the primary outcomes. In the case of the pragmatic studies that were included in this meta-analysis this was a major issue because the secondary outcomes were not adjusted for variations in the baseline covariates.
Additionally, studies that are pragmatic can present challenges in the gathering and interpretation of safety data. This is because adverse events are usually self-reported and are prone to delays in reporting, inaccuracies or coding deviations. It is essential to improve the quality and accuracy of the outcomes in these trials.
Results
Although the definition of pragmatism does not require that all clinical trials are 100% pragmatic there are benefits to including pragmatic components in trials. These include:
Incorporating routine patients, the trial results can be more quickly translated into clinical practice. However, pragmatic trials may have disadvantages. The right type of heterogeneity, for example could allow a study to extend its findings to different settings or patients. However the wrong type of heterogeneity could reduce the assay sensitivity and, consequently, decrease the ability of a study to detect minor treatment effects.
A number of studies have attempted to categorize pragmatic trials with a variety of definitions and scoring systems. Schwartz and Lellouch1 created a framework to discern between explanation-based studies that prove a physiological or clinical hypothesis, and pragmatic studies that guide the choice for appropriate therapies in the real-world clinical practice. Their framework included nine domains, each scored on a scale ranging from 1-5, with 1 indicating more lucid and 5 indicating more pragmatic. The domains were recruitment and setting, delivery of intervention with flexibility, follow-up 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 systematic reviews had a higher average scores in the majority of domains, with lower scores in the primary analysis domain.
This distinction in the primary analysis domain can be explained by the way that most pragmatic trials analyse data. Certain explanatory trials however do not. The overall score for systematic reviews that were pragmatic was lower when the areas of organisation, flexible delivery and following-up were combined.
It is important to note that a pragmatic trial doesn't necessarily mean a low-quality trial, and in fact there is an increasing number of clinical trials (as defined by MEDLINE search, however it is neither sensitive nor specific) that use the term "pragmatic" in their abstracts or titles. These terms may indicate an increased appreciation of pragmatism in titles and abstracts, but it's not clear whether this is evident in the content.
Conclusions
As the value of evidence from the real world becomes more widespread the pragmatic trial has gained popularity in research. They are randomized trials that evaluate real-world treatment options with clinical trials in development. They involve patient populations closer to those treated in regular care. This method can help overcome the limitations of observational research, for example, the biases that are associated with the use of volunteers and the limited availability and coding variations in national registries.
Pragmatic trials offer other advantages, like the ability to use existing data sources and a higher probability of detecting meaningful distinctions from traditional trials. However, these trials could have some limitations that limit their reliability and generalizability. The participation rates in certain trials could be lower than anticipated due to the health-promoting effect, financial incentives, or competition from other research studies. The need to recruit individuals quickly reduces the size of the sample and impact of many pragmatic trials. Practical trials aren't always equipped with controls to ensure that any observed differences aren't due to biases that occur during the trial.
The authors of the Pragmatic Free Trial Meta identified 48 RCTs self-labeled as pragmatic and that were published until 2022. The PRECIS-2 tool was employed to evaluate the degree of pragmatism. It includes areas like eligibility criteria, recruitment flexibility and adherence to intervention and follow-up. They discovered that 14 of the trials scored pragmatic or highly practical (i.e., scoring 5 or higher) in one or more of these domains, and that the majority of these were single-center.
Trials that have high pragmatism scores tend to have broader criteria for eligibility than conventional RCTs. They also have patients from a variety of hospitals. The authors argue that these characteristics can help make pragmatic trials more meaningful and applicable to everyday practice, but they don't necessarily mean that a trial using a pragmatic approach is free of bias. Moreover, the pragmatism of a trial is not a definite characteristic; a pragmatic trial that does not contain all the characteristics of a explanatory trial may yield reliable and relevant results.
