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, which allows for multiple and varied meta-epidemiological research studies to evaluate the effect of treatment on trials with different levels of pragmatism, as well as other design features.
Background
Pragmatic studies are increasingly recognized as providing real-world evidence for clinical decision-making. However, the use of the term "pragmatic" is not uniform and its definition and assessment requires further clarification. The purpose of pragmatic trials is to inform policy and clinical practice decisions, not to confirm an hypothesis that is based on a clinical or physiological basis. A pragmatic study should strive to be as close as possible to actual clinical practices, including recruiting participants, setting up, implementation and delivery of interventions, determining and analysis results, as well as primary analysis. This is a significant difference between explanatory trials, as described by Schwartz & Lellouch1 which are designed to prove a hypothesis in a more thorough manner.
Studies that are truly pragmatic should not attempt to blind participants or healthcare professionals, as this may cause distortions in estimates of the effect of treatment. Pragmatic trials will also recruit patients from different health care settings to ensure that the results can be generalized to the real world.
Additionally, pragmatic trials should focus on outcomes that are vital to patients, such as quality of life or functional recovery. This is particularly important in trials that involve surgical procedures that are invasive or have potentially serious adverse events. The CRASH trial29, for example, focused on functional outcomes to evaluate a two-page case report with an electronic system for the monitoring of patients in hospitals suffering from chronic heart failure. Similarly, the catheter trial28 used urinary tract infections caused by catheters as the primary outcome.
In addition to these aspects the pragmatic trial should also reduce the procedures for conducting trials and data collection requirements to reduce costs. Additionally pragmatic trials should strive to make their findings as relevant to actual clinical practice as they can by ensuring that their primary analysis is the intention-to-treat approach (as described in CONSORT extensions for pragmatic trials).
Many RCTs which do not meet the requirements for pragmatism however, they have characteristics that are contrary to pragmatism have been published in journals of various types and incorrectly labeled pragmatic. This could lead to misleading claims of pragmatism, and the use of the term needs to be standardized. The development of a PRECIS-2 tool that offers a standardized objective assessment of pragmatic features is a first step.
Methods
In a practical trial it is the intention to inform clinical or policy decisions by showing how an intervention could be incorporated into real-world routine care. This differs from explanation trials that 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,

The PRECIS-2 tool evaluates an RCT on 9 domains, ranging from 1 to 5 (very pragmatist). In this study the areas of recruitment, organization, flexibility in delivery, flexibility in adherence, and follow-up were awarded high scores. However, the primary outcome and the method for missing data scored below the pragmatic limit. This suggests that it is possible to design a trial using excellent pragmatic features without damaging the quality of its results.
However, it is difficult to assess how pragmatic a particular trial is since pragmaticity is not a definite characteristic; certain aspects of a study can be more pragmatic than others. A trial's pragmatism can be affected by changes to the protocol or logistics during the trial. In addition, 36% of the 89 pragmatic trials identified by Koppenaal and
프라그마틱 무료스핀 (
gpsites.win) colleagues 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 their sponsors agree that these trials aren't blinded.
A common feature of pragmatic research is that researchers attempt to make their findings more meaningful by analyzing subgroups within the trial sample. However, this often leads to unbalanced comparisons with a lower statistical power, thereby increasing 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 differences in covariates at the baseline.
Furthermore practical trials can present challenges in the gathering and interpretation of safety data. It is because adverse events are usually self-reported and are susceptible to delays, inaccuracies or coding errors. It is therefore crucial to enhance the quality of outcomes ascertainment in these trials, and ideally by using national registry databases instead of relying on participants to report adverse events in the trial's own database.
Results
Although the definition of pragmatism may not require that clinical trials be 100% pragmatist there are benefits to including pragmatic components in trials. These include:
Enhancing sensitivity to issues in the real world which reduces cost and size of the study as well as allowing trial results to be faster transferred into real-world clinical practice (by including patients from routine care). But pragmatic trials can be a challenge. The right amount of heterogeneity, for example could help a study generalise its findings to many different settings or patients. However the wrong type of heterogeneity could reduce the sensitivity of an assay, and therefore reduce a trial's power to detect even minor effects of treatment.
Numerous studies have attempted to categorize pragmatic trials, using various definitions and scoring systems. Schwartz and Lellouch1 have developed a framework to distinguish between research studies that prove a physiological or clinical hypothesis as well as pragmatic trials that inform the selection of appropriate treatments in clinical practice. The framework consisted of nine domains scored on a 1-5 scale which indicated that 1 was more informative and 5 being more pragmatic. The domains were recruitment, setting, intervention delivery and follow-up, as well as flexible 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 et al10 created an adaptation to this assessment, dubbed the Pragmascope that was easier to use in systematic reviews. They discovered that pragmatic reviews scored higher on average in all domains, but scored lower in the primary analysis domain.
The difference in the primary analysis domain could be due to the fact that the majority of pragmatic trials analyze their data in the intention to treat manner however some explanation trials do not. The overall score was lower for pragmatic systematic reviews when the domains of organisation, flexible delivery, and follow-up were merged.
It is important to remember that a pragmatic trial does not necessarily mean a low-quality trial, and in fact there is a growing number of clinical trials (as defined by MEDLINE search, however this is neither specific nor sensitive) which use the word 'pragmatic' in their abstract or title. The use of these words in abstracts and titles could indicate a greater understanding of the importance of pragmatism however, it is not clear if this is reflected in the contents of the articles.
Conclusions
In recent years, pragmatic trials are increasing in popularity in research because the value of real-world evidence is increasingly recognized. They are clinical trials randomized which compare real-world treatment options rather than experimental treatments under development. They include patients which are more closely resembling the patients who receive routine care, they use comparators which exist in routine practice (e.g. existing drugs), and
프라그마틱 they rely on participant self-report of outcomes. This method has the potential to overcome limitations of observational studies, such as the limitations of relying on volunteers and the lack of accessibility and coding flexibility in national registries.
Other advantages of pragmatic trials include the possibility of using existing data sources, as well as a higher chance of detecting meaningful changes than traditional trials. However, they may be prone to limitations that compromise their reliability and generalizability. For example, participation rates in some trials might be lower than expected due to the healthy-volunteer effect as well as financial incentives or competition for participants from other research studies (e.g., industry trials). Many pragmatic trials are also limited by the need to enroll participants on time. In addition, some pragmatic trials don't have controls to ensure that the observed differences aren't due to biases in the conduct of trials.
The authors of the Pragmatic Free Trial Meta identified RCTs published up to 2022 that self-described themselves as pragmatic. The PRECIS-2 tool was used to determine pragmatism. It covers areas like eligibility criteria, recruitment flexibility as well as adherence to interventions and follow-up. They discovered that 14 trials scored highly pragmatic or pragmatic (i.e. scoring 5 or higher) in at least one of these domains.
Studies with high pragmatism scores tend to have broader criteria for eligibility than conventional RCTs. They also contain populations from various hospitals. The authors argue that these traits can make pragmatic trials more effective and relevant to daily practice, but they do not guarantee that a trial conducted in a pragmatic manner is free of bias. The pragmatism is not a fixed attribute the test that doesn't have all the characteristics of an explanatory study could still yield reliable and beneficial results.
