Pragmatic Free Trial Meta
Pragmatic Free Trial Meta is a non-commercial, open data platform and infrastructure that facilitates research on pragmatic trials. It shares clean trial data and ratings using PRECIS-2, which allows for multiple and varied meta-epidemiological studies to examine the effects of treatment across trials that have different levels of pragmatism and other design features.
Background
Pragmatic trials provide evidence from the real world 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 measurement require clarification. Pragmatic trials should be designed to inform clinical practice and policy decisions, not to confirm a physiological or

A pragmatic study should strive to be as close to real-world clinical practice as is possible, including the participation of participants, setting up and design, the delivery and execution of the intervention, and the determination and analysis of outcomes as well as primary analyses. This is a major difference between explanation-based trials, as described by Schwartz and Lellouch1 that are designed to test a hypothesis in a more thorough manner.
Trials that are truly practical should be careful not to blind patients or clinicians as this could lead to bias in the estimation of the effect of treatment. Practical trials also involve patients from different healthcare settings to ensure that their outcomes can be compared to the real world.
Additionally, clinical trials should focus on outcomes that matter to patients, such as quality of life and functional recovery. This is particularly important for trials involving invasive procedures or those with potentially serious adverse events. The CRASH trial29, for example focused on the functional outcome to compare a two-page report with an electronic system for the monitoring of hospitalized patients with chronic heart failure. Similarly, the catheter trial28 focused on urinary tract infections that are symptomatic of catheters as its primary outcome.
In addition to these aspects, pragmatic trials should minimize the procedures for conducting trials and data collection requirements to reduce costs. Additionally, pragmatic trials should seek to make their results as applicable to clinical practice as possible by making sure that their primary method of analysis follows the intention-to treat approach (as described in CONSORT extensions for pragmatic trials).
Despite these criteria however, a large number of RCTs with features that challenge pragmatism have been incorrectly self-labeled pragmatic and published in journals of all kinds. This could lead to false claims about pragmatism, and the usage of the term should be made more uniform. The development of a PRECIS-2 tool that can provide an objective and standardized assessment of pragmatic features is a good start.
Methods
In a pragmatic study it is the intention to inform policy or clinical decisions by showing how an intervention could be integrated into routine treatment in real-world situations. Explanatory trials test hypotheses regarding the causal-effect relationship in idealized settings. In this way, pragmatic trials could have lower internal validity than studies that explain and are more susceptible to biases in their design, analysis, and conduct. Despite these limitations, pragmatic trials can provide valuable information to decisions in the context of healthcare.
The PRECIS-2 tool measures the degree of pragmatism within an RCT by scoring it across 9 domains ranging from 1 (very explicit) to 5 (very pragmatic). In this study, the areas of recruitment, organization, flexibility in delivery, flexibility in adherence, and follow-up were awarded high scores. However, the main outcome and method of missing data was scored below the pragmatic limit. This suggests that it is possible to design a trial that has high-quality pragmatic features, without compromising the quality of its outcomes.
However, it is difficult to assess the degree of pragmatism a trial really is because pragmaticity is not a definite quality; certain aspects of a trial can be more pragmatic than others. Additionally, logistical or protocol modifications during the course of an experiment can alter its score in pragmatism. In addition 36% of 89 pragmatic trials discovered by Koppenaal et al were placebo-controlled, or conducted prior to approval and a majority of them were single-center. They are not close to the standard practice and can only be called pragmatic if the sponsors agree that such trials are not blinded.
A common aspect of pragmatic studies is that researchers try to make their findings more meaningful by analyzing subgroups within the trial sample. However, this can lead to unbalanced comparisons and lower statistical power, which increases the likelihood of missing or misinterpreting differences in the primary outcome. This was the case in the meta-analysis of pragmatic trials because secondary outcomes were not adjusted for covariates' differences at the time of baseline.
In addition, pragmatic studies can pose difficulties in the gathering and interpretation of safety data. It is because adverse events tend to be self-reported, and therefore are prone to errors, delays or coding differences. Therefore, it is crucial to enhance the quality of outcomes assessment in these trials, in particular by using national registries instead of relying on participants to report adverse events on the trial's database.
Results
While the definition of pragmatism may not mean that trials must be 100 100% pragmatic, there are benefits of including pragmatic elements in clinical trials. These include:
Increasing sensitivity to real-world issues which reduces the size of studies and their costs as well as allowing trial results to be more quickly transferred into real-world clinical practice (by including patients who are routinely treated). However, pragmatic trials can also have disadvantages. For instance, the appropriate type of heterogeneity can help the trial to apply its findings to a variety of settings and patients. However the wrong type of heterogeneity can reduce assay sensitivity and therefore lessen the ability of a study to detect even minor effects of treatment.
Numerous studies have attempted to categorize pragmatic trials, with various definitions and scoring systems. Schwartz and Lellouch1 created a framework to discern between explanation-based studies that confirm the physiological hypothesis or clinical hypothesis and pragmatic studies that inform the choice for appropriate therapies in the real-world clinical practice. Their framework comprised nine domains, each scoring on a scale of 1 to 5 with 1 indicating more lucid and 5 indicating more practical. The domains were recruitment, setting, intervention delivery, flexible adherence, follow-up and primary analysis.
The original PRECIS tool3 included similar domains and a scale of 1 to 5. Koppenaal and colleagues10 created an adaptation of the assessment, dubbed the Pragmascope, that was easier to use for systematic reviews. They found that pragmatic systematic reviews had a higher average scores in the majority of domains, but lower scores in the primary analysis domain.
The difference in the primary analysis domain can be explained by the way that most pragmatic trials analyze data. Certain explanatory trials however don't. The overall score was lower for systematic reviews that were pragmatic when the domains of organisation, flexible delivery and

It is important to understand that a pragmatic trial doesn't necessarily mean a low quality trial, and in fact there is a growing number of clinical trials (as defined by MEDLINE search, but this is neither sensitive nor specific) that use the term 'pragmatic' in their abstract or title. These terms could indicate that there is a greater awareness of pragmatism within titles and abstracts, but it's not clear whether this is evident in the content.
Conclusions
In recent years, pragmatic trials are becoming more popular in research as the value of real-world evidence is increasingly recognized. They are clinical trials randomized that evaluate real-world alternatives to care rather than experimental treatments under development. They include populations of patients that are more similar to those treated in routine care, they use comparators which exist in routine practice (e.g. existing medications),

This approach has the potential to overcome the limitations of observational studies, such as the biases associated with reliance on volunteers, and the limited availability and the variability of coding in national registries.
Other benefits of pragmatic trials include the possibility of using existing data sources, and a greater likelihood of detecting meaningful changes than traditional trials. However, these tests could be prone to limitations that undermine their validity and generalizability. The participation rates in certain trials may be lower than anticipated due to the health-promoting effect, financial incentives, or competition from other research studies. The requirement to recruit participants quickly restricts the sample size and impact of many pragmatic trials. In addition certain pragmatic trials lack controls to ensure that the observed differences are not due to biases in the conduct of trials.
The authors of the Pragmatic Free Trial Meta identified RCTs published from 2022 to 2022 that self-described themselves as pragmatic. They evaluated pragmatism using the PRECIS-2 tool that includes the domains eligibility criteria and recruitment criteria, as well as flexibility in adherence to intervention and follow-up. They found that 14 trials scored highly pragmatic or pragmatic (i.e. scoring 5 or above) in at least one of these domains.
Studies with high pragmatism scores are likely to have more criteria for eligibility than conventional RCTs. They also include patients from a variety of hospitals. These characteristics, according to the authors, can make pragmatic trials more relevant and relevant to everyday practice. However, they cannot ensure that a study is free of bias. The pragmatism principle is not a definite characteristic; a pragmatic test that does not possess all the characteristics of an explanatory study could still yield valid and useful outcomes.
