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 examine the effects of treatment across trials with different levels of pragmatism and other design features.
Background
Pragmatic studies provide real-world evidence that can be used to make clinical decisions. However, the usage of the term "pragmatic" is inconsistent and its definition and assessment requires further clarification. Pragmatic trials should be designed to guide clinical practice and policy decisions, rather than confirm an hypothesis that is based on a clinical or physiological basis. A pragmatic trial should try to be as close as possible to the real-world clinical practice that include recruitment of participants, setting up, delivery and execution of interventions, determining and analysis outcomes, and primary analysis. This is a major distinction from explanatory trials (as described by Schwartz and Lellouch1) that are intended to provide a more thorough proof of the hypothesis.
Studies that are truly pragmatic should be careful not to blind patients or the clinicians in order to lead to distortions in estimates of the effect of treatment. Pragmatic trials should also seek to recruit patients from a variety of health care settings to ensure that the results can be compared to the real world.
Furthermore, trials that are pragmatic must be focused on outcomes that matter to patients, such as the quality of life and functional recovery. This is particularly relevant when it comes to trials that involve the use of invasive procedures or potential for serious adverse events. The CRASH trial29 compared a 2-page report with an electronic monitoring system for patients in hospitals suffering from chronic cardiac failure. The trial with a catheter, however, used symptomatic catheter associated urinary tract infections as its primary outcome.
In addition to these features pragmatic trials should also reduce the requirements for data collection and trial procedures to cut costs and time commitments. Furthermore pragmatic trials should strive to make their results as applicable to real-world clinical practice as they can by ensuring that their primary analysis follows the intention-to treat approach (as described in CONSORT extensions for pragmatic trials).
Many RCTs that don't meet the requirements for pragmatism but contain features contrary to pragmatism have been published in journals of different types and incorrectly labeled as pragmatic. This could lead to misleading claims of pragmaticity, and the use of the term should be standardized. The development of a PRECIS-2 tool that can provide a standardized objective evaluation of pragmatic aspects is the first step.
Methods
In a pragmatic research study it is the intention to inform policy or clinical decisions by demonstrating how an intervention can be integrated into routine treatment in real-world settings. Explanatory trials test hypotheses about the causal-effect relationship in idealized environments. In this way, pragmatic trials can have less internal validity than explanatory studies and are more susceptible to biases in their design analysis, conduct, 프라그마틱 홈페이지 and design. Despite their limitations, pragmatic studies can be a valuable source of information for decision-making within the context of healthcare.
The PRECIS-2 tool measures the degree of pragmatism in an RCT by assessing it on 9 domains, ranging from 1 (very explanatory) to 5 (very pragmatic). In this study, the domains of recruitment, organisation and flexibility in delivery, flexible adherence and follow-up scored high. However, the principal outcome and the method of missing data were scored below the practical limit. This suggests that it is possible to design a trial that has good pragmatic features without harming the quality of the outcomes.
It is difficult to determine the degree of pragmatism that is present in a study because pragmatism is not a have a single characteristic. Certain aspects of a study may 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. They are not close to the norm and can only be referred to as pragmatic if their sponsors agree that such trials aren't blinded.
A typical feature of pragmatic research is that researchers attempt to make their findings more meaningful by studying subgroups of the trial sample. However, this can lead to unbalanced results and lower statistical power, increasing the likelihood of missing or misinterpreting differences in the primary outcome. This was a problem during the meta-analysis of pragmatic trials because secondary outcomes were not corrected for covariates that differed at the time of baseline.
Furthermore, pragmatic trials can also be a challenge in the collection and interpretation of safety data. This is because adverse events are generally reported by the participants themselves and are prone to delays in reporting, inaccuracies or coding errors. It is therefore important to improve the quality of outcomes for these trials, in particular by using national registries rather than relying on participants to report adverse events on the trial's database.
Results
Although the definition of pragmatism may not require that all clinical trials be 100% pragmatist there are benefits to including pragmatic components in trials. These include:
By incorporating routine patients, the results of trials are more easily translated into clinical practice. However, pragmatic trials have disadvantages. For instance, the appropriate type of heterogeneity can help a trial to generalise its results to different patients and settings; however the wrong kind of heterogeneity may reduce the assay's sensitivity and therefore lessen the ability of a study to detect small treatment effects.
A variety of studies have attempted to categorize pragmatic trials with various definitions and scoring systems. Schwartz and Lellouch1 developed a framework to differentiate between explanation studies that support a physiological or clinical hypothesis and pragmatic studies that help inform the selection of appropriate therapies in clinical practice. The framework was comprised of nine domains that were evaluated on a scale of 1-5 with 1 being more explanatory while 5 being more pragmatic. The domains were recruitment and setting, delivery of intervention, 프라그마틱 체험 flexible adherence, follow-up and 슬롯 primary analysis.
The original PRECIS tool3 was based on a similar scale and 프라그마틱 무료스핀 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 systematic reviews had a higher average scores in the majority of domains, with lower scores in the primary analysis domain.
The difference in the main analysis domain could be explained by the fact that most pragmatic trials analyze their data in an intention to treat method however some explanation trials do not. The overall score for pragmatic systematic reviews was lower when the domains of management, flexible delivery and follow-up were merged.
It is important to note that a pragmatic trial doesn't necessarily mean a low-quality trial, and there is a growing number of clinical trials (as defined by MEDLINE search, however this is not specific or sensitive) which use the word 'pragmatic' in their title or abstract. The use of these terms in abstracts and titles may suggest a greater awareness of the importance of pragmatism, however, it is not clear if this is evident in the content of the articles.
Conclusions
As the value of evidence from the real world becomes more widespread, pragmatic trials have gained traction in research. They are randomized studies that compare real-world care alternatives to clinical trials in development. They involve patient populations closer to those treated in regular care. This method is able to overcome the limitations of observational research, like the biases associated with the reliance on volunteers as well as the insufficient availability and codes that vary in national registers.
Pragmatic trials have other advantages, such as the ability to draw on existing data sources and a higher probability of detecting meaningful differences from traditional trials. However, they may still have limitations which undermine their validity and generalizability. For example the rates of participation in some trials might be lower than anticipated due to the healthy-volunteer effect and incentives to pay or compete for participants from other research studies (e.g. industry trials). The requirement to recruit participants in a timely fashion also reduces the size of the sample and the impact of many pragmatic trials. Additionally certain pragmatic trials do not have controls to ensure that the observed differences aren't due to biases in trial conduct.
The authors of the Pragmatic Free Trial Meta identified 48 RCTs self-labeled as pragmatic and were published up to 2022. They assessed pragmatism using the PRECIS-2 tool, which includes the domains eligibility criteria and recruitment criteria, as well as flexibility in intervention adherence, and follow-up. They discovered that 14 of the trials scored highly or pragmatic practical (i.e. scores of 5 or higher) in any one or more of these domains and that the majority were single-center.
Trials with a high pragmatism score tend to have broader eligibility criteria than traditional RCTs which have very specific criteria that are not likely to be used in clinical practice, and they contain patients from a broad variety of hospitals. The authors claim that these characteristics could make pragmatic trials more effective and useful for everyday practice, but they do not guarantee that a pragmatic trial is completely free of bias. The pragmatism is not a definite characteristic and a test that doesn't have all the characteristics of an explicative study could still yield reliable and beneficial results.
