Pragmatic Free Trial Meta
Pragmatic Free Trail Meta is an open data platform that allows research into pragmatic trials. It shares clean trial data and ratings using PRECIS-2, allowing for multiple and diverse meta-epidemiological research studies to evaluate the effect of treatment on trials that employ different levels of pragmatism as well as other design features.
Background
Pragmatic trials provide real-world evidence that can be used to make clinical decisions. However, the use of the term "pragmatic" is inconsistent and its definition as well as assessment requires further clarification. Pragmatic trials are designed to inform clinical practices and policy choices, rather than confirm a physiological hypothesis or clinical hypothesis. A pragmatic study should strive to be as close as is possible to the real-world clinical practice, including recruiting participants, setting up, delivery and implementation of interventions,

The trials that are truly pragmatic must avoid attempting to blind participants or clinicians, as this may lead to distortions in estimates of the effects of treatment. The pragmatic trials also include patients from different healthcare settings to ensure that their results can be applied to the real world.
Furthermore studies that are pragmatic should focus on outcomes that are vital for patients, such as quality of life or 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 to monitor the health of patients admitted to hospitals with chronic heart failure. Similarly, the catheter trial28 focused on symptomatic catheter-associated urinary tract infections as its primary outcome.
In addition to these characteristics the pragmatic trial should also reduce the trial's procedures and data collection requirements to reduce costs. Furthermore, pragmatic trials should seek to make their results as relevant to actual clinical practice as possible by ensuring that their primary analysis is the intention-to-treat approach (as described in CONSORT extensions for pragmatic trials).
Many RCTs that do not meet the criteria for pragmatism, but contain features contrary to pragmatism have been published in journals of various types and incorrectly labeled as pragmatic. This can lead to misleading claims about pragmatism, and the use of the term should be standardized. The development of the PRECIS-2 tool, which provides an objective standard for assessing practical features, is a good first step.
Methods
In a pragmatic study, the goal is to inform policy or clinical decisions by showing how an intervention can 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. Consequently, pragmatic trials may be less reliable than explanatory trials,

The PRECIS-2 tool evaluates an RCT on 9 domains, with scores ranging between 1 and 5 (very pragmatic). In this study, the areas of recruitment, organization, flexibility in delivery, flexibility in adherence, and follow-up scored high. However, the primary outcome and method of missing data scored below the pragmatic limit. This suggests that a trial could be designed with effective practical features, yet not damaging the quality.
It is difficult to determine the amount of pragmatism in a particular study because pragmatism is not a possess a specific attribute. Some aspects of a research study can be more pragmatic than other. A trial's pragmatism could be affected by modifications 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. This means that they are not quite as typical and can only be described as pragmatic if their sponsors are tolerant of the lack of blinding in these trials.
A typical feature of pragmatic research is that researchers try to make their findings more meaningful by analyzing subgroups of the trial sample. This can result in unbalanced analyses with lower statistical power. This increases the chance of omitting or ignoring differences in the primary outcomes. In the instance of the pragmatic trials that were included in this meta-analysis this was a significant problem because the secondary outcomes weren't adjusted for variations in baseline covariates.
Furthermore, pragmatic studies can pose difficulties in the gathering and interpretation of safety data. This is due to the fact that adverse events tend to be self-reported, and therefore are prone to delays, inaccuracies or coding variations. Therefore, it is crucial to improve the quality of outcome assessment in these trials, in particular by using national registries instead of relying on participants to report adverse events on a trial's own database.
Results
Although the definition of pragmatism may not require that clinical trials be 100% pragmatic there are benefits to including pragmatic components in trials. These include:
Enhancing sensitivity to issues in the real world as well as reducing cost and size of the study as well as allowing trial results to be more quickly implemented into clinical practice (by including patients from routine care). However, pragmatic trials may also have disadvantages. The right kind of heterogeneity for instance, can help a study extend its findings to different patients or settings. However the wrong kind of heterogeneity can decrease the sensitivity of the test and, consequently, decrease the ability of a study to detect minor treatment effects.
Numerous studies have attempted to classify pragmatic trials with a variety of definitions and scoring systems. Schwartz and Lellouch1 created an approach to distinguish between research studies that prove the clinical or physiological hypothesis and pragmatic trials that help in the selection of appropriate therapies in real-world clinical practice. Their framework comprised 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 adhering to the program and

The original PRECIS tool3 had similar domains and scales from 1 to 5. Koppenaal et. al10 devised an adaptation of this assessment, known as the Pragmascope which was more user-friendly to use for systematic reviews. They found that pragmatic reviews scored higher in all domains, but scored lower in the primary analysis domain.
This difference in primary analysis domains can be explained by the way that most pragmatic trials approach 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 follow-up were merged.
It is important to remember that a pragmatic study should not necessarily mean a low-quality study. In fact, there are increasing numbers of clinical trials that employ the term 'pragmatic' either in their abstract or title (as defined by MEDLINE, but that is not precise nor sensitive). The use of these terms in titles and abstracts could indicate a greater understanding of the importance of pragmatism but it is unclear whether this is reflected in the content of the articles.
Conclusions
As the value of real-world evidence grows popular, pragmatic trials have gained popularity in research. They are randomized trials that evaluate real-world care alternatives to new treatments that are being developed. They include patient populations more closely resembling those treated in regular medical care. This method can help overcome the limitations of observational research which include the biases that arise from relying on volunteers and limited availability and coding variability in national registries.
Pragmatic trials also have advantages, like the ability to use existing data sources and a higher likelihood of detecting meaningful distinctions from traditional trials. However, these trials could have some limitations that limit their credibility and generalizability. For instance the rates of participation in some trials could be lower than anticipated due to the healthy-volunteer influence and incentives to pay or compete for participants from other research studies (e.g. industry trials). The requirement to recruit participants in a timely manner also limits the sample size and impact of many pragmatic trials. In addition, some pragmatic trials lack controls to ensure that the observed differences are not due to biases in trial conduct.
The authors of the Pragmatic Free Trial Meta identified 48 RCTs self-labeled as pragmatist and published from 2022. The PRECIS-2 tool was employed to assess the degree of pragmatism. It includes areas like eligibility criteria, recruitment flexibility, adherence to intervention, and follow-up. They found that 14 trials scored highly pragmatic or pragmatic (i.e. scoring 5 or more) in at least one of these domains.
Trials with high pragmatism scores are likely to have more lenient criteria for eligibility than conventional RCTs. They also have populations from many different hospitals. These characteristics, according to the authors, may make pragmatic trials more relevant and applicable in the daily clinical. However, they cannot guarantee that a trial is free of bias. In addition, the pragmatism that is present in trials is not a definite characteristic A pragmatic trial that does not possess all the characteristics of a explanatory trial can yield reliable and relevant results.
