Pragmatic Free Trial Meta
Pragmatic Free Trail Meta is an open data platform that facilitates research into pragmatic trials. It collects and distributes clean trial data, ratings and evaluations using PRECIS-2. This allows for a variety of meta-epidemiological analyses to compare treatment effect estimates across trials with different levels of pragmatism.
Background
Pragmatic trials are increasingly acknowledged as providing evidence from the real world to support clinical decision-making. The term "pragmatic", however, is a word that is often used in contradiction and its definition and measurement require clarification. The purpose of pragmatic trials is to guide the practice of clinical medicine and policy decisions, not to prove a physiological or clinical hypothesis. 프라그마틱 should try to be as similar to actual clinical practice as possible, including in the recruitment of participants, setting and design, the delivery and implementation of the intervention, determination and analysis of outcomes as well as primary analyses. This is a major distinction between explanation-based trials, as defined by Schwartz and Lellouch1 that are designed to confirm a hypothesis in a more thorough manner.
Studies that are truly pragmatic must be careful not to blind patients or healthcare professionals in order to lead to bias in estimates of the effects of treatment. Pragmatic trials will also recruit patients from various healthcare settings to ensure that their results can be generalized to the real world.
Finally, pragmatic trials must concentrate on outcomes that are important to patients, such as quality of life and functional recovery. This is particularly relevant for trials involving surgical procedures that are invasive or have potential for serious adverse events. The CRASH trial29 compared a two-page report with an electronic monitoring system for hospitalized patients with chronic heart failure. The trial with a catheter, on the other hand was based on symptomatic catheter-related urinary tract infections as its primary outcome.
In addition to these aspects pragmatic trials should reduce the trial's procedures and requirements for data collection to reduce costs. Additionally pragmatic trials should strive to make their findings as relevant to actual clinical practice as they can by making sure that their primary analysis follows the intention-to treat approach (as described in CONSORT extensions for pragmatic trials).
Despite these criteria, a number of RCTs with features that defy pragmatism have been incorrectly self-labeled pragmatic and published in journals of all types. This could lead to false claims about pragmatism, and the term's use should be standardized. The creation of a PRECIS-2 tool that can provide an objective, standardized evaluation of pragmatic aspects is a first step.
Methods
In a pragmatic study the aim is to inform policy or clinical decisions by demonstrating how an intervention could be integrated into routine care in real-world situations. This is distinct from explanation trials that test hypotheses about the cause-effect connection in idealized conditions. In this way, pragmatic trials may have lower internal validity than studies that explain and be more prone to biases in their design as well as analysis and conduct. Despite their limitations, pragmatic research can be a valuable source of data for making decisions within the healthcare context.
The PRECIS-2 tool evaluates the level of pragmatism that is present in an RCT by assessing it on 9 domains ranging from 1 (very explanatory) to 5 (very pragmatic). In this study, the recruitment, organization, flexibility in delivery, flexible adherence and follow-up domains received high scores, however the primary outcome and the procedure for missing data were not at the practical limit. This suggests that it is possible to design a trial using good pragmatic features without damaging the quality of its results.
It is difficult to determine the amount of pragmatism in a particular trial since pragmatism doesn't possess a specific characteristic. Some aspects of a study can be more pragmatic than other. A trial's pragmatism can be affected by modifications to the protocol or the logistics during the trial. Koppenaal and colleagues found that 36% of the 89 pragmatic studies were placebo-controlled or conducted prior to the licensing. The majority of them were single-center. Thus, they are not very close to usual practice and are only pragmatic if their sponsors are tolerant of the lack of blinding in such trials.
Furthermore, a common feature of pragmatic trials is that the researchers try to make their results more valuable by studying subgroups of the trial sample. However, this often leads to unbalanced results and lower statistical power, thereby increasing the risk of either not detecting or misinterpreting the results of the primary outcome. In the instance of the pragmatic trials that were included in this meta-analysis this was a significant problem since the secondary outcomes weren't adjusted for the differences in the baseline covariates.
In addition, pragmatic studies can present challenges in the gathering and interpretation of safety data. This is due to the fact that adverse events are typically reported by participants themselves and are prone to reporting delays, inaccuracies or coding errors. It is important to increase the accuracy and quality of outcomes in these trials.
Results
While the definition of pragmatism may not require that all trials are 100 100% pragmatic, there are some advantages to incorporating pragmatic components into clinical trials. These include:
Incorporating routine patients, the results of trials are more easily translated into clinical practice. However, pragmatic trials may be a challenge. For instance, the right type of heterogeneity could help a trial to generalise its results to many different settings and patients. However, the wrong type of heterogeneity may reduce the assay's sensitiveness and consequently decrease the ability of a trial to detect minor treatment effects.
A number of studies have attempted to classify pragmatic trials with a variety of definitions and scoring systems. Schwartz and Lellouch1 have developed a framework for distinguishing between explanatory trials that confirm a physiological or clinical hypothesis, and pragmatic trials that inform the choice of appropriate therapies in clinical practice. The framework was comprised of nine domains, each scoring on a scale of 1 to 5, with 1 being more informative and 5 indicating more practical. The domains covered recruitment and setting up, the delivery of intervention, flex adhering to the program and primary analysis.
The initial PRECIS tool3 featured similar domains and an assessment scale ranging from 1 to 5. Koppenaal et al10 devised an adaptation of this assessment, dubbed the Pragmascope that was easier to use in systematic reviews. They found that pragmatic systematic reviews had higher average score in most domains, with lower scores in the primary analysis domain.
This distinction in the primary analysis domains can be explained by the way most pragmatic trials analyze data. Some explanatory trials, however don't. 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 study does not necessarily mean a low-quality study. In fact, there is increasing numbers of clinical trials which use the word 'pragmatic,' either in their title or abstract (as defined by MEDLINE but which is neither precise nor sensitive). These terms may signal a greater understanding of pragmatism in abstracts and titles, but it's unclear whether this is evident in content.
Conclusions
In recent years, pragmatic trials are becoming more popular in research as the value of real world evidence is becoming increasingly acknowledged. They are randomized clinical trials that compare real-world care alternatives instead of experimental treatments under development, they have patient populations that more closely mirror those treated in routine care, they employ comparisons that are commonplace in practice (e.g. existing drugs) and rely on participant self-report of outcomes. This method has the potential to overcome limitations of observational studies, such as the biases that arise from relying on volunteers and limited availability and coding variability in national registries.
Other advantages of pragmatic trials are the ability to use 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 the participation rates in certain trials could be lower than expected due to the healthy-volunteer influence and financial incentives or competition for participants from other research studies (e.g. industry trials). Practical trials are often restricted by the need to enroll participants on time. Certain pragmatic trials lack controls to ensure that the 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 were published from 2022. 슬롯 -2 tool was used to determine the degree of pragmatism. It covers domains such as eligibility criteria as well as recruitment flexibility as well as adherence to interventions and follow-up. They discovered 14 trials scored highly pragmatic or pragmatic (i.e. scoring 5 or higher) in at least one of these domains.
Trials with a high pragmatism rating tend to have more expansive eligibility criteria than traditional RCTs which have very specific criteria that are not likely to be found in the clinical setting, and comprise patients from a wide variety of hospitals. The authors argue that these traits can make pragmatic trials more meaningful and useful for daily practice, but they do not guarantee that a pragmatic trial is completely free of bias. The pragmatism is not a definite characteristic; a pragmatic test that doesn't have all the characteristics of an explicative study can still produce valuable and valid results.
