Pragmatic Free Trial Meta Pragmatic Free Trial Meta is a noncommercial open data platform and infrastructure that supports research on pragmatic trials It collects and distributes cleaned trial data ratings and evaluations using PRECIS2 This allows for diverse metaepidemiological analyses that compare treatment effect estimates across trials with different levels of pragmatism Background Pragmatic studies provide realworld evidence that can be used to make clinical decisions The term pragmatic however is used inconsistently and its definition and assessment need further clarification Pragmatic trials are designed to guide the practice of clinical medicine and policy choices rather than prove a physiological or clinical hypothesis A pragmatic study should try to be as similar to realworld clinical practice as possible such as the selection of participants setting and design as well as the execution of the intervention and the determination and analysis of outcomes as well as primary analyses This is a major distinction between explanatory trials as described by Schwartz Lellouch1 which are designed to confirm a hypothesis in a more thorough manner Trials that are truly practical should not attempt to blind participants or clinicians as this may result in bias in estimates of the effects of treatment Practical trials also involve patients from various health care settings to ensure that their results can be generalized to the real world Furthermore trials that are pragmatic must focus on outcomes that matter to patients like the quality of life and functional recovery This is especially important when trials involve the use of invasive procedures or could have dangerous adverse impacts The CRASH trial29 for instance focused on functional outcomes to compare a twopage report with an electronic system for monitoring of hospitalized patients with chronic heart failure and the catheter trial28 focused on urinary tract infections caused by catheters as its primary outcome In addition to these characteristics pragmatic trials should also reduce the procedures for conducting trials and requirements for data collection to cut costs and time commitments Additionally pragmatic trials should aim to make their findings as relevant to realworld clinical practices as they can This can be achieved by ensuring their primary analysis is based on the intention to treat method as described within CONSORT extensions Despite these criteria however a large number of RCTs with features that defy the notion of pragmatism were incorrectly labeled pragmatic and published in journals of all types This can lead to false claims of pragmatism and the usage of the term should be standardized The creation of a PRECIS2 tool that provides a standardized objective evaluation of the pragmatic characteristics is a good start Methods In a pragmatic trial the goal is to inform clinical or policy decisions by demonstrating how the intervention can be incorporated into realworld routine care Explanatory trials test hypotheses regarding the causaleffect relationship in idealized conditions In this way pragmatic trials may have a lower internal validity than explanatory studies and are more susceptible to biases in their design as well as analysis and conduct Despite these limitations pragmatic trials can contribute valuable information to decisionmaking in healthcare The PRECIS2 tool evaluates an RCT on 9 domains with scores ranging from 1 to 5 very pragmatist In this study the areas of recruitment organization and flexibility in delivery flexibility in adherence and followup were awarded high scores However the primary outcome and the method of missing data scored below the pragmatic limit This suggests that a trial can be designed with wellthoughtout practical features but without compromising its quality It is hard to determine the degree of pragmatism within a specific trial because pragmatism does not have a binary characteristic Certain aspects of a study can be more pragmatic than others Furthermore logistical or protocol changes during the trial may alter its score on pragmatism In addition 36 of the 89 pragmatic trials discovered by Koppenaal et al were placebocontrolled or conducted prior to licensing and the majority were singlecenter They are not close to the norm and are only considered pragmatic if their sponsors accept that such trials arent blinded Furthermore a common feature of pragmatic trials is that the researchers attempt to make their findings more meaningful by analysing subgroups of the trial This can lead to unbalanced results and lower statistical power thereby increasing the likelihood of missing or misinterpreting the results of the primary outcome This was a problem during the metaanalysis of pragmatic trials as secondary outcomes were not corrected for covariates that differed at baseline In addition pragmatic trials can also 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 prone to reporting delays inaccuracies or coding errors It is essential to improve the quality and accuracy of the results in these trials Results Although the definition of pragmatism may not require that all trials are 100 pragmatic there are advantages of including pragmatic elements in clinical trials These include Incorporating routine patients the results of trials can be more quickly translated into clinical practice However pragmatic trials have their disadvantages The right type of heterogeneity like can help a study extend its findings to different settings or patients However the wrong type of heterogeneity could reduce the assay sensitivity and consequently lessen the power of a trial to detect even minor effects of treatment Numerous 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 prove a physiological hypothesis or clinical hypothesis and pragmatic studies that inform the choice for appropriate therapies in real world clinical practice The framework was comprised of nine domains that were scored on a scale ranging from 15 with 1 indicating more lucid and 5 indicating more practical The domains included recruitment setting intervention delivery flexible adherence followup and primary analysis The original PRECIS tool3 was built on the same scale and domains Koppenaal et al10 devised an adaptation of this assessment dubbed the Pragmascope which was more userfriendly to use for systematic reviews They discovered that pragmatic reviews scored higher in most domains but scored lower in the primary analysis domain This difference in primary analysis domain can be explained by the way that most pragmatic trials analyze data Some explanatory trials however dont The overall score was lower for systematic reviews that were pragmatic when the domains on organisation flexible delivery and followup were combined It is crucial to keep in mind that a pragmatic study should not necessarily mean a lowquality study In fact there are increasing numbers of clinical trials that employ the term pragmatic either in their abstract or title as defined by MEDLINE but that is neither sensitive nor precise The use of these terms in titles and abstracts may suggest a greater awareness of the importance of pragmatism but it isnt clear if this is manifested in the content of the articles Conclusions As appreciation for the value of realworld evidence becomes increasingly popular and pragmatic trials have gained traction in research They are randomized studies that compare realworld care alternatives to experimental treatments in development More suggestions include patient populations more closely resembling those treated in regular care This method is able to overcome the limitations of observational research like the biases that come with the use of volunteers and the limited availability and codes that vary in national registers Other benefits of pragmatic trials include the possibility of using existing data sources and a higher likelihood of detecting meaningful changes than traditional trials However they may have some limitations that limit their reliability and generalizability Participation rates in some trials may be lower than expected because of the healthyvolunteering effect financial incentives or competition from other research studies The need to recruit individuals in a timely fashion also limits the sample size and impact of many pragmatic trials Additionally some pragmatic trials dont have 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 48 RCTs selflabeled as pragmatic and were published from 2022 They assessed pragmatism by using the PRECIS2 tool that includes the eligibility criteria for domains and recruitment criteria as well as flexibility in adherence to interventions and followup They found that 14 of these trials scored highly or pragmatic practical ie scoring 5 or higher in any one or more of these domains and that the majority of these were singlecenter Trials with a high pragmatism rating tend to have broader eligibility criteria than traditional RCTs which include very specific criteria that arent likely to be used in clinical practice and they include populations from a wide variety of hospitals The authors claim that these characteristics could make pragmatic trials more effective and useful for daily practice but they do not guarantee that a trial using a pragmatic approach is completely free of bias The pragmatism is not a definite characteristic the test that does not possess all the characteristics of an explanatory study may still yield valuable and valid results
