Pragmatic Free Trial Meta Pragmatic Free Trail Meta is an open data platform that allows research into pragmatic trials It collects and distributes cleaned trial data ratings and evaluations using PRECIS2 This permits a variety of metaepidemiological studies to evaluate the effects of treatment across trials with different levels of pragmatism Background Pragmatic trials provide evidence from the real world that can be used to make clinical decisions However the usage of the term pragmatic is inconsistent and its definition and evaluation requires clarification Pragmatic trials should be designed to guide clinical practice and policy decisions not to confirm a physiological or clinical hypothesis A pragmatic trial should also try to be as similar to actual clinical practice as is possible including its participation of participants setting and design the delivery and implementation of the intervention and the determination and analysis of the outcomes and primary analyses This is a major distinction between explanatory trials as described by Schwartz and Lellouch1 which are designed to confirm the hypothesis in a more thorough way Truely pragmatic trials should not be blind participants or clinicians This can lead to a bias in the estimates of the effects of treatment The pragmatic trials also include patients from different health care settings to ensure that their results can be applied to the real world Additionally clinical trials should focus on outcomes that matter to patients like quality of life and functional recovery This is particularly important in trials that require the use of invasive procedures or could have harmful adverse effects The CRASH trial29 for example focused on the functional outcome to compare a 2page casereport with an electronic system for monitoring of hospitalized patients with chronic heart failure Similarly the catheter trial28 utilized symptomatic catheterassociated urinary tract infections as the primary outcome In addition to these aspects pragmatic trials should reduce the trial procedures and data collection requirements in order to reduce costs Finally pragmatic trials should strive to make their results as relevant to actual clinical practice as possible by making sure that their primary method of analysis is based on the intentiontotreat method as described in CONSORT extensions for pragmatic trials Despite these requirements however a large number of RCTs with features that defy the concept of pragmatism have been mislabeled as pragmatic and published in journals of all kinds This can lead to misleading claims of pragmatism and the terms use should be made more uniform The development of the PRECIS2 tool which provides an objective standard for assessing pragmatic features is a good first step Methods In a pragmatic study 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 lower internal validity than studies that explain and be more prone to biases in their design analysis and conduct Despite these limitations pragmatic trials can provide valuable information to decisionmaking in the context of healthcare The PRECIS2 tool evaluates an RCT on 9 domains with scores ranging between 1 and 5 very pragmatic In this study the recruitment organisation flexibility delivery flexible adherence and followup domains received high scores but the primary outcome and the method of missing data were not at the limit of practicality This suggests that it is possible to design a trial that has good pragmatic features without compromising the quality of its outcomes However its difficult to judge how pragmatic a particular trial is since pragmatism is not a binary attribute some aspects of a trial can be more pragmatic than others Additionally logistical or protocol changes during the trial may alter its score in pragmatism In addition 36 of the 89 pragmatic trials identified by Koppenaal et al were placebocontrolled or conducted before licensing and the majority were singlecenter This means that they are not as common and can only be called pragmatic when their sponsors are accepting of the absence of blinding in these trials A common aspect of pragmatic studies is that researchers try to make their findings more meaningful by studying subgroups within the trial sample However this often leads to unbalanced comparisons with a lower statistical power which increases the risk of either not detecting or incorrectly detecting differences in the primary outcome In the case of the pragmatic trials that were included in this metaanalysis this was a serious issue because the secondary outcomes were not adjusted to account for the differences in the baseline covariates Additionally studies that are pragmatic may pose challenges to collection and interpretation safety data This is due to the fact that adverse events are generally reported by the participants themselves and are susceptible to reporting delays inaccuracies or coding deviations It is essential to increase the accuracy and quality of the results in these trials Results Although the definition of pragmatism does not require that all clinical trials are 100 pragmatic there are benefits of including pragmatic elements in trials These include Increased sensitivity to realworld issues which reduces cost and size of the study and allowing the study results to be faster implemented into clinical practice by including patients who are routinely treated However pragmatic trials may also have drawbacks For instance the appropriate kind of heterogeneity can allow the trial to apply its results to different settings and patients However the wrong type of heterogeneity may reduce the assays sensitivity and therefore lessen the ability of a trial to detect even minor effects of treatment Many studies have attempted classify pragmatic trials using different definitions and scoring methods Schwartz and Lellouch1 have developed a framework that can discern between explanationbased studies that confirm the physiological hypothesis or clinical hypothesis and pragmatic studies that help inform the selection of appropriate therapies in clinical practice The framework was composed of nine domains that were evaluated on a scale of 15 with 1 being more explanatory while 5 was more practical The domains included recruitment setting up delivery of intervention flexible adherence and primary analysis The initial PRECIS tool3 had similar domains and scales from 1 to 5 무료슬롯 et al10 developed an adaptation of the assessment known as the Pragmascope which was more userfriendly to use for systematic reviews They discovered that pragmatic systematic reviews had higher average score in most domains but lower scores in the primary analysis domain The difference in the primary analysis domain can be explained by the way most pragmatic trials analyse data Some explanatory trials however do not The overall score for pragmatic systematic reviews was lower when the areas of organisation flexible delivery and followingup were combined It is important to note that the term pragmatic trial does not necessarily mean a poor quality trial and in fact there is an increasing rate of clinical trials as defined by MEDLINE search but this is not specific nor sensitive that employ the term pragmatic in their title or abstract The use of these words in abstracts and titles could indicate a greater understanding of the importance of pragmatism but it isnt clear if this is manifested in the contents of the articles Conclusions As the importance of realworld evidence grows widespread the pragmatic trial has gained popularity in research They are randomized clinical trials which compare realworld treatment options rather than experimental treatments under development They involve populations of patients that more closely mirror those treated in routine care they employ comparisons that are commonplace in practice eg existing medications and they depend on the selfreporting of participants about outcomes This approach could help overcome the limitations of observational studies which include the biases associated with reliance on volunteers and the limited availability and coding variability in national registries Pragmatic trials offer 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 be prone to limitations that undermine their reliability and generalizability The participation rates in certain trials may be lower than anticipated due to the healthpromoting effect financial incentives or competition from other research studies Practical trials are often restricted by the need to recruit participants in a timely manner In addition some pragmatic trials dont have controls to ensure that the observed differences are not due to biases in trial conduct The authors of the Pragmatic Free Trial Meta identified RCTs published up to 2022 that selfdescribed as pragmatism They assessed pragmatism by using the PRECIS2 tool that includes the domains eligibility criteria recruitment flexibility in intervention adherence and followup They found 14 trials scored highly pragmatic or pragmatic ie scoring 5 or above in at least one of these domains Trials with a high pragmatism score tend to have more expansive eligibility criteria than traditional RCTs which have very specific criteria that are unlikely to be found in the clinical environment and they contain patients from a broad range of hospitals The authors suggest that these traits can make pragmatic trials more meaningful and useful for everyday practice but they do not necessarily guarantee that a pragmatic trial is free from bias The pragmatism characteristic is not a definite characteristic and a test that does not possess all the characteristics of an explanatory study may still yield valid and useful outcomes
