Pragmatic Free Trial Meta Pragmatic Free Trial Meta is a noncommercial open data platform and infrastructure that facilitates research on pragmatic trials It shares clean trial data and ratings using PRECIS2 permitting multiple and varied metaepidemiological research studies to compare treatment effects estimates across trials that employ different levels of pragmatism as well as other design features Background Pragmatic studies provide realworld evidence that can be used to make clinical decisions The term pragmatic however is not used in a consistent manner and its definition and measurement need further clarification Pragmatic trials must be designed to inform policy and clinical practice decisions rather than to prove the validity of a clinical or physiological hypothesis A pragmatic study should strive to be as close as is possible to actual clinical practices which include the recruiting participants setting design delivery and implementation of interventions determining and analysis results as well as primary analyses This is a significant difference between explanatory trials as described by Schwartz Lellouch1 which are designed to prove the hypothesis in a more thorough manner The most pragmatic trials should not blind participants or clinicians This can result in bias in the estimations of the effect of treatment Pragmatic trials should also seek to attract patients from a wide range of health care settings to ensure that their findings can be applied to the real world Finally pragmatic trials should focus on outcomes that are vital for patients such as quality of life or functional recovery This is particularly important in trials that involve invasive procedures or those with potentially dangerous adverse events The CRASH trial29 compared a 2page report with an electronic monitoring system for patients in hospitals with chronic heart failure The catheter trial28 on the other hand was based on symptomatic catheterrelated urinary tract infections as its primary outcome In addition to these aspects pragmatic trials should minimize the procedures for conducting trials and requirements for data collection to reduce costs Finaly pragmatic trials should aim to make their results as applicable to current clinical practice as is possible This can be achieved by ensuring their primary analysis is based on the intention to treat method as described 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 varying 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 PRECIS2 tool that offers a standardized objective assessment of pragmatic features is a good start Methods In a pragmatic study the goal is to inform policy or clinical decisions by showing how an intervention could be implemented into routine care Explanatory trials test hypotheses about the causaleffect relationship in idealized settings Therefore pragmatic trials could have lower internal validity than explanatory trials and could be more susceptible to bias in their design conduct and analysis Despite these limitations pragmatic trials can provide valuable information to decisions in the context of healthcare The PRECIS2 tool assesses the degree of pragmatism within an RCT by assessing it on 9 domains that range from 1 very explicit to 5 very pragmatic In this study the recruitment organization flexibility in delivery and followup domains received high scores however the primary outcome and the procedure for missing data fell below the practical limit This suggests that it is possible to design a trial with excellent pragmatic features without compromising the quality of its results However its difficult to judge the degree of pragmatism a trial is since the pragmatism score is not a binary quality certain aspects of a study can be more pragmatic than others A trials pragmatism can be affected by changes to the protocol or logistics during the trial Koppenaal and colleagues found that 36 of 89 pragmatic studies were placebocontrolled or conducted prior to the licensing They also found that the majority were singlecenter Therefore they arent quite as typical and can only be described as pragmatic if their sponsors are tolerant of the lack of blinding in such trials A common aspect of pragmatic research is that researchers try to make their findings more meaningful by studying subgroups within the trial sample This can lead to unbalanced comparisons and lower statistical power which increases the likelihood of missing or misinterpreting the results of the primary outcome In the case of the pragmatic studies included in this metaanalysis this was a major issue since the secondary outcomes werent adjusted for the differences in baseline covariates Additionally studies that are pragmatic may pose challenges to collection and interpretation of safety data This is due to the fact that adverse events are generally reported by the participants themselves and prone to delays in reporting inaccuracies or coding deviations It is therefore important 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 on the trials own database Results While the definition of pragmatism does not require that all trials are 100 pragmatic there are advantages to including pragmatic components in clinical trials These include Incorporating routine patients the trial results can be translated more quickly into clinical practice However pragmatic trials can also have disadvantages 프라그마틱 환수율 of heterogeneity like can help a study expand its findings to different settings or patients However the wrong type can decrease the sensitivity of the test and thus decrease the ability of a study to detect minor treatment effects A variety of studies have attempted to categorize pragmatic trials with various definitions and scoring systems Schwartz and Lellouch1 created a framework to discern between explanationbased studies that prove the physiological hypothesis or clinical hypothesis and pragmatic studies that inform the selection of appropriate therapies in real world clinical practice The framework was composed of nine domains assessed on a scale of 15 with 1 being more informative and 5 was more pragmatic The domains included recruitment of intervention setting up delivery of intervention flexible adherence and primary analysis The initial PRECIS tool3 featured similar domains and an assessment scale ranging from 1 to 5 Koppenaal et al10 developed an adaptation of this assessment dubbed the Pragmascope that was easier to use for systematic reviews They discovered that pragmatic reviews scored higher on average across all domains however they scored lower in the primary analysis domain The difference in the primary analysis domains can be due to the way in which most pragmatic trials approach data Certain explanatory trials however do not The overall score was lower for systematic reviews that were pragmatic when the domains on the organization flexibility of delivery and followup were merged It is crucial to keep in mind that a pragmatic study does not mean that a trial is of poor quality In fact there are an increasing number of clinical trials that employ the term pragmatic either in their title or abstract as defined by MEDLINE but that is neither precise nor sensitive The use of these terms in titles and abstracts could indicate a greater understanding of the importance of pragmatism but it is unclear whether this is manifested in the contents of the articles Conclusions In recent times pragmatic trials are increasing in popularity in research because the value of realworld evidence is becoming increasingly acknowledged They are clinical trials that are randomized that evaluate realworld alternatives to care instead of experimental treatments under development They have patient populations that are more similar to the ones who are treated in routine medical care they utilize comparators that are used in routine practice eg existing drugs and they rely on participant selfreport of outcomes This method can help overcome the limitations of observational research such as the biases that are associated with the reliance on volunteers and the limited availability and codes that vary in national registers Other advantages of pragmatic trials include the ability to use existing data sources and a higher probability of detecting significant changes than traditional trials However pragmatic tests may be prone to limitations that undermine their reliability and generalizability For example participation rates in some trials could be lower than anticipated due to the healthyvolunteer influence and incentives to pay or compete for participants from other research studies eg industry trials Many pragmatic trials are also restricted by the necessity to recruit participants in a timely manner Some pragmatic trials also lack controls to ensure that observed differences arent caused by biases that occur during the trial The authors of the Pragmatic Free Trial Meta identified 48 RCTs selflabeled as pragmatic and were published from 2022 They assessed pragmatism using the PRECIS2 tool that includes the domains eligibility criteria as well as recruitment flexibility in adherence to intervention and followup They discovered that 14 of the trials scored as highly or pragmatic practical ie scores of 5 or more in one or more of these domains and that the majority were singlecenter Trials that have a high pragmatism score tend to have more expansive eligibility criteria than traditional RCTs that have specific criteria that are unlikely to be used in the clinical setting and comprise patients from a wide variety of hospitals The authors suggest that these characteristics can help make the pragmatic trials more relevant and relevant to everyday clinical practice however they do not guarantee that a pragmatic trial is completely free of bias The pragmatism characteristic is not a fixed attribute a pragmatic test that doesnt have all the characteristics of an explanation study may still yield valuable and valid results
