Pragmatic Free Trial Meta Pragmatic Free Trial Meta is a non-commercial, open data platform and infrastructure that facilitates research on pragmatic trials. It gathers and distributes clean trial data, ratings, and evaluations using PRECIS-2. This allows for diverse meta-epidemiological analyses to examine the effect of treatment across trials with different levels of pragmatism. Background Pragmatic studies are increasingly acknowledged as providing evidence from the real world to support clinical decision-making. However, the usage of the term "pragmatic" is not uniform and its definition as well as 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 similar to real-world clinical practice as possible, including in its recruitment of participants, setting and design, the delivery and execution of the intervention, as well as the determination and analysis of the outcomes, and primary analysis. This is a significant difference between explanatory trials, as defined by Schwartz & Lellouch1, which are designed to test the hypothesis in a more thorough manner. The most pragmatic trials should not blind participants or clinicians. This can result in a bias in the estimates of the effect of treatment. The trials that are pragmatic should also try to recruit patients from a wide range of health care settings to ensure that their findings are generalizable to the real world. Finally, pragmatic trials must be focused on outcomes that matter to patients, such as quality of life and functional recovery. This is particularly relevant for trials involving invasive procedures or those with potential dangerous adverse events. The CRASH trial29, for instance focused on the functional outcome to compare a 2-page case-report with an electronic system for the monitoring of hospitalized patients with chronic heart failure, and the catheter trial28 used urinary tract infections that are symptomatic of catheters as its primary outcome. In addition to these aspects pragmatic trials should reduce the requirements for data collection and trial procedures to cut down on costs and time commitments. Additionally, pragmatic trials should aim to make their results as applicable to current clinical practices as possible. This can be achieved by ensuring that their primary analysis is based on the intention-to treat method (as defined in CONSORT extensions). Many RCTs that do not meet the criteria for pragmatism but have features that are contrary to pragmatism have been published in journals of various types and incorrectly labeled as pragmatic. This can lead to misleading claims of pragmatism and the term's use should be made more uniform. The creation of the PRECIS-2 tool, which offers an objective and standard assessment of pragmatic characteristics, is a good first step. Methods In a pragmatic trial, the aim is to inform clinical or policy decisions by demonstrating how an intervention would be incorporated into real-world routine care. This is different from explanatory trials that test hypotheses about the cause-effect connection in idealized settings. Consequently, pragmatic trials may be less reliable than explanatory trials and might be more susceptible to bias in their design, conduct and analysis. Despite their limitations, pragmatic research can be a valuable source of information for decision-making within the context of healthcare. The PRECIS-2 tool evaluates the degree of pragmatism in an RCT by assessing it on 9 domains that range from 1 (very explicit) to 5 (very pragmatic). In this study, the domains of recruitment, organisation as well as flexibility in delivery flexible adherence and follow-up scored high. However, the primary outcome and method of missing data was scored below the pragmatic limit. This suggests that a trial can be designed with well-thought-out practical features, yet not compromising its quality. It is difficult to determine the amount of pragmatism within a specific trial because pragmatism does not have a binary attribute. Some aspects of a study may be more pragmatic than others. Furthermore, logistical or protocol modifications made during the trial may alter its score on pragmatism. Koppenaal and colleagues discovered that 36% of the 89 pragmatic studies were placebo-controlled or conducted prior to the licensing. They also found that the majority were single-center. Therefore, they aren't very close to usual practice and can only be called pragmatic if their sponsors are tolerant of the lack of blinding in these trials. Another common aspect of pragmatic trials is that researchers attempt to make their findings more meaningful by analysing subgroups of the trial sample. This can lead to unbalanced results and lower statistical power, which increases the likelihood of missing or incorrectly detecting differences in the primary outcome. This was a problem in the meta-analysis of pragmatic trials due to the fact that secondary outcomes were not adjusted for covariates' differences at the baseline. Additionally, studies that are pragmatic can pose difficulties in the gathering and interpretation of safety data. This is due to the fact that adverse events are typically self-reported, and therefore are prone to delays, errors or coding differences. Therefore, it is crucial to improve the quality of outcome for these trials, ideally by using national registries 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 all trials are 100% pragmatic, there are benefits of including pragmatic elements in clinical trials. These include: By including routine patients, the results of trials are more easily translated into clinical practice. However, pragmatic trials have disadvantages. The right type of heterogeneity, like could help a study extend its findings to different settings or patients. However the wrong type of heterogeneity could decrease the sensitivity of the test and thus decrease the ability of a study to detect small treatment effects. A variety of studies have attempted to categorize pragmatic trials using various definitions and scoring methods. Schwartz and Lellouch1 developed a framework to distinguish between explanatory studies that confirm a physiological hypothesis or clinical hypothesis and pragmatic studies that inform the selection of appropriate therapies in the real-world clinical practice. The framework consisted of nine domains that were scored on a 1-5 scale which indicated that 1 was more lucid while 5 being more pragmatic. The domains were recruitment setting, setting, intervention delivery, flexible adherence, follow-up and primary analysis. The original PRECIS tool3 was based on a similar scale and domains. Koppenaal and colleagues10 created an adaptation of this assessment, dubbed the Pragmascope that was simpler to use for systematic reviews. They found that pragmatic systematic reviews had higher average scores across all domains but lower scores in the primary analysis domain. The difference in the primary analysis domains could be due to the way in which most pragmatic trials analyse data. Certain explanatory trials however don't. The overall score was lower for pragmatic systematic reviews when the domains on the organization, flexibility of delivery and follow-up were merged. It is important to remember that a pragmatic study does not mean a low-quality trial. In fact, there are a growing number of clinical trials that employ the term "pragmatic" either in their abstract or title (as defined by MEDLINE but which is not precise nor sensitive). The use of these terms in titles and abstracts could suggest a greater awareness of the importance of pragmatism, however, it is not clear if this is manifested in the content of the articles. Conclusions In recent years, pragmatic trials are gaining popularity in research as the value of real-world evidence is becoming increasingly acknowledged. They are randomized studies that compare real-world care alternatives to new treatments that are being developed. ????? ?? ?? include patient populations that are more similar to those who receive treatment in regular care. This method could help overcome the limitations of observational research which include the biases that arise from relying on volunteers, and the limited accessibility and coding flexibility in national registries. Pragmatic trials offer other advantages, like the ability to use existing data sources and a higher probability of detecting meaningful distinctions from traditional trials. However, they may still have limitations which undermine their validity and generalizability. For example the rates of participation in some trials may 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). Many pragmatic trials are also limited by the need to recruit participants quickly. Additionally certain pragmatic trials lack 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. They assessed pragmatism using the PRECIS-2 tool, which consists of the domains eligibility criteria, recruitment, flexibility in intervention adherence and follow-up. ????? ?? discovered that 14 of these trials scored pragmatic or highly sensible (i.e. scores of 5 or higher) in any one or more of these domains, and that the majority of them were single-center. Trials with a high pragmatism rating tend to have higher eligibility criteria than traditional RCTs, which include very specific criteria that are not likely to be present in the clinical environment, and they comprise patients from a wide variety of hospitals. The authors argue that these characteristics could make pragmatic trials more effective and relevant to everyday practice, but they do not guarantee that a trial conducted in a pragmatic manner is completely free of bias. The pragmatism characteristic is not a fixed attribute and a test that does not have all the characteristics of an explanatory study can still produce valid and useful outcomes.
