Pragmatic Free Trial Meta Pragmatic Free Trial Meta is a free and noncommercial open data platform and infrastructure that facilitates research on pragmatic trials It collects and shares cleaned trial data and ratings using PRECIS2 allowing for multiple and diverse metaepidemiological studies to evaluate the effect of treatment on trials that employ different levels of pragmatism as well as other design features Background Pragmatic trials are increasingly acknowledged as providing evidence from the real world for clinical decisionmaking However the use of the term pragmatic is not uniform and its definition and evaluation requires clarification The purpose of pragmatic trials is to guide the practice of clinical medicine and policy decisions rather than prove a physiological or clinical hypothesis A pragmatic study should strive to be as close to the realworld clinical environment as is possible including the recruitment of participants setting and design of the intervention its delivery and implementation of the intervention and the determination and analysis of outcomes as well as primary analyses This is a major distinction between explanationbased trials as defined by Schwartz and Lellouch1 which are designed to confirm the hypothesis in a more thorough manner Studies that are truly pragmatic should be careful not to blind patients or healthcare professionals in order to cause bias in estimates of the effect of treatment Pragmatic trials should also seek to enroll patients from a variety of health care settings so that their results can be applied to the real world Furthermore trials that are pragmatic must focus on outcomes that matter to patients such as quality of life and functional recovery This is particularly important for trials involving the use of invasive procedures or potential dangerous adverse events The CRASH trial29 for instance focused on functional outcomes to compare a twopage report with an electronic system for monitoring of patients admitted to hospitals with chronic heart failure In addition the catheter trial28 utilized symptomatic catheterassociated urinary tract infections as the primary outcome In addition to these aspects pragmatic trials should minimize trial procedures and datacollection requirements to reduce costs and time commitments Additionally the aim of pragmatic trials is to make their findings as relevant to actual clinical practices as they can This can be accomplished by ensuring that their primary analysis is based on an intentionto treat method as described within CONSORT extensions Many RCTs that do not meet the requirements for pragmatism but have features that are contrary to pragmatism have been published in journals of various kinds and incorrectly labeled pragmatic This could lead to misleading claims of pragmatism and the use of the term needs to be standardized The creation of a PRECIS2 tool that provides an objective standardized evaluation of the pragmatic characteristics is a good start Methods In a pragmatic study it is the intention to inform clinical or policy decisions by demonstrating how an intervention would be integrated into everyday routine care This is different from explanatory trials that test hypotheses regarding the causaleffect relationship in idealized situations Therefore pragmatic trials could have less internal validity than explanatory trials and might be more susceptible to bias in their design conduct and analysis Despite these limitations pragmatic trials may contribute valuable information to decisionmaking in healthcare The PRECIS2 tool evaluates an RCT on 9 domains ranging between 1 and 5 very pragmatist In this study the recruitment organization flexibility in delivery flexible adherence and followup domains scored high scores but the primary outcome and the procedure for missing data were below the practical limit This suggests that it is possible to design a trial with highquality pragmatic features without compromising the quality of its outcomes It is hard to determine the degree of pragmatism in a particular study because pragmatism is not a have a binary attribute Certain aspects of a study can be more pragmatic than others The pragmatism of a trial can be affected by modifications to the protocol or logistics during the trial Additionally 36 of the 89 pragmatic trials identified by Koppenaal and colleagues were placebocontrolled or conducted before licensing and the majority were singlecenter They are not in line with the norm and can only be called pragmatic if their sponsors agree that these trials arent blinded Furthermore a common feature of pragmatic trials is that researchers try to make their results more relevant by analyzing subgroups of the sample This can result in unbalanced analyses that have less statistical power This increases the possibility of missing or misdetecting differences in the primary outcomes In the case of the pragmatic trials included in this metaanalysis this was a major issue since the secondary outcomes were not adjusted to account for the differences in the baseline covariates Additionally studies that are pragmatic can present challenges in the collection and interpretation of safety data This is due to the fact that adverse events are typically selfreported and therefore are prone to errors delays or coding differences It is essential to increase the accuracy and quality of the results in these trials Results Although the definition of pragmatism may not require that all trials be 100 percent pragmatic there are advantages to incorporating pragmatic components into clinical trials These include Incorporating routine patients the results of the trial are more easily translated into clinical practice But pragmatic trials can be a challenge For instance the appropriate type of heterogeneity could help a study to generalize its results to many different patients and settings however the wrong kind of heterogeneity can reduce assay sensitiveness and consequently lessen the ability of a trial to detect minor treatment effects A number of studies have attempted to classify pragmatic trials with various definitions and scoring systems Schwartz and Lellouch1 created a framework to differentiate between explanation studies that support a physiological or clinical hypothesis and pragmatic studies that help inform the selection of appropriate therapies in clinical practice The framework was comprised of nine domains each scoring on a scale of 1 to 5 with 1 indicating more lucid and 5 indicating more practical The domains covered recruitment setting up delivery of intervention flexible adherence and primary analysis The initial PRECIS tool3 featured similar domains and scales from 1 to 5 Koppenaal et al10 devised an adaptation to this assessment dubbed the Pragmascope which was more userfriendly to use in systematic reviews They discovered that pragmatic reviews scored higher in all domains but scored lower in the primary analysis domain This difference in primary analysis domains can be due to the way in which most pragmatic trials approach data Some explanatory trials however do not The overall score was lower for pragmatic systematic reviews when the domains of organisation flexible delivery and followup were combined 프라그마틱 is important to note that a pragmatic trial does not necessarily mean a low quality trial and indeed there is an increasing number of clinical trials as defined by MEDLINE search however this is neither specific or sensitive that use the term pragmatic in their abstract or title 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 reflected in the content of the articles Conclusions In recent years pragmatic trials have been gaining popularity in research as the importance of realworld evidence is becoming increasingly acknowledged They are randomized trials that compare real world care alternatives to clinical trials in development They are conducted with populations of patients more closely resembling those treated in regular care This method has the potential to overcome limitations of observational studies which include the biases that arise from relying on volunteers and the lack of accessibility and coding flexibility in national registries Other advantages of pragmatic trials include the possibility of using existing data sources and a greater chance of detecting meaningful changes than traditional trials However pragmatic tests may be prone to limitations that undermine their effectiveness and generalizability The participation rates in certain trials could be lower than anticipated due to the healthyvolunteering effect financial incentives or competition from other research studies The need to recruit individuals in a timely manner also restricts the sample size and the impact of many pragmatic trials Certain pragmatic trials lack controls to ensure that observed differences arent due to biases that occur during the trial The authors of the Pragmatic Free Trial Meta identified RCTs published from 2022 to 2022 that selfdescribed as pragmatism They assessed pragmatism using the PRECIS2 tool that includes the eligibility criteria for domains recruitment flexibility in adherence to interventions and followup They discovered that 14 of the trials scored highly or pragmatic sensible ie scores of 5 or more in one or more of these domains and that the majority were singlecenter Trials with a high pragmatism score tend to have higher eligibility criteria than traditional RCTs which have very specific criteria that arent likely to be found in the clinical environment and they comprise patients from a wide variety of hospitals According to the authors can make pragmatic trials more useful and useful in everyday clinical However they dont ensure that a study is free of bias Moreover the pragmatism of the trial is not a definite characteristic and a pragmatic trial that does not have all the characteristics of an explanatory trial may yield reliable and relevant results
