helpful resources is an open data platform that facilitates research into pragmatic trials. It collects and distributes clean trial data, ratings and evaluations using PRECIS-2. This permits a variety of meta-epidemiological analyses that 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 for clinical decision-making. However, the usage of the term “pragmatic” is not uniform and its definition and evaluation requires clarification. Pragmatic trials are intended to guide the practice of clinical medicine and policy decisions rather than prove a physiological or clinical hypothesis. A pragmatic trial should aim to be as close as possible to real-world clinical practices that include recruiting participants, setting, design, delivery and implementation of interventions, determination and analysis outcomes, and primary analysis. This is a significant difference between explanatory trials, as defined by Schwartz and Lellouch1 that are designed to prove the hypothesis in a more thorough manner. Trials that are truly pragmatic should be careful not to blind patients or clinicians in order to result in bias in estimates of the effect of treatment. Practical trials should also aim to recruit patients from a variety of health care settings to ensure that the results can be compared to the real world. Furthermore, pragmatic trials should focus on outcomes that are vital to patients, such as quality of life or functional recovery. This is particularly important when trials involve the use of invasive procedures or could have serious adverse consequences. The CRASH trial29, for example was focused on functional outcomes to compare a 2-page case-report with an electronic system for monitoring of hospitalized patients with chronic heart failure, and the catheter trial28 used urinary tract infections caused by catheters as its primary outcome. In addition to these features, pragmatic trials should minimize the procedures for conducting trials and requirements for data collection to reduce costs and time commitments. Additionally the aim of pragmatic trials is to make their findings as relevant to real-world clinical practice as is possible. This can be achieved by ensuring that their primary analysis is based on the intention to treat method (as defined in CONSORT extensions). Despite these requirements, many RCTs with features that challenge the concept of pragmatism have been mislabeled as pragmatic and published in journals of all types. This can lead to false 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 initial step. Methods In a pragmatic study it is the intention to inform clinical or policy decisions by demonstrating how an intervention could be integrated into routine treatment in real-world situations. Explanatory trials test hypotheses regarding the cause-effect relation within idealized environments. Therefore, pragmatic trials could have lower internal validity than explanatory trials and may be more susceptible to bias in their design, conduct, and analysis. Despite their limitations, pragmatic research can be a valuable source of data for making decisions within the healthcare context. The PRECIS-2 tool evaluates the degree of pragmatism in an RCT by scoring it across 9 domains that range from 1 (very explanatory) to 5 (very pragmatic). In this study the areas of recruitment, organisation, flexibility in delivery, flexibility in adherence, and follow-up scored high. However, the main outcome and method of missing data was scored below the pragmatic limit. This suggests that a trial can be designed with good practical features, yet not compromising its quality. It is difficult to determine the degree of pragmatism that is present in a trial since pragmatism doesn't have a single attribute. Certain aspects of a research study can be more pragmatic than others. The pragmatism of a trial can be affected by changes to the protocol or the logistics during the trial. In addition, 36% of the 89 pragmatic trials discovered by Koppenaal et al were placebo-controlled or conducted prior to licensing and most were single-center. They aren't in line with the norm and are only called pragmatic if their sponsors accept that the trials are not blinded. A common feature of pragmatic studies is that researchers attempt to make their findings more meaningful by analyzing subgroups of the trial sample. This can lead to unbalanced comparisons with a lower statistical power, which increases the risk of either not detecting or incorrectly detecting differences in the primary outcome. This was the case in the meta-analysis of pragmatic trials as secondary outcomes were not adjusted for differences in covariates at baseline. Furthermore, pragmatic trials can also present challenges in the collection and interpretation of safety data. This is due to the fact that adverse events are usually self-reported and are susceptible to delays in reporting, inaccuracies or coding deviations. It is crucial to improve the accuracy and quality of the results in these trials. Results While the definition of pragmatism doesn't require that all clinical trials be 100% pragmatist There are advantages of including pragmatic elements in trials. These include: By incorporating routine patients, the results of trials can be translated more quickly into clinical practice. However, pragmatic trials may also have drawbacks. The right type of heterogeneity for instance could allow a study to generalise its findings to many different patients or settings. 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 using various definitions and scoring methods. Schwartz and Lellouch1 created a framework to differentiate between explanation studies that prove the physiological hypothesis or clinical hypothesis, and pragmatic studies that guide the choice for appropriate therapies in the real-world clinical practice. The framework was comprised of nine domains that were scored on a scale ranging from 1-5, with 1 indicating more explanatory and 5 indicating more pragmatic. The domains included recruitment, setting, intervention delivery with flexibility, follow-up and primary analysis. The original PRECIS tool3 featured similar domains and an assessment scale ranging from 1 to 5. Koppenaal and colleagues10 created an adaptation of this assessment, dubbed the Pragmascope which was more user-friendly to use for systematic reviews. They found that pragmatic systematic reviews had a higher average scores in the majority of domains but lower scores in the primary analysis domain. This difference in the main analysis domain could be due to the fact that the majority of pragmatic trials analyse their data in an intention to treat way however some explanation trials do not. The overall score for pragmatic systematic reviews was lower when the areas of organisation, flexible delivery and following-up were combined. It is crucial to keep in mind that a pragmatic study should not mean a low-quality trial. In fact, there is an increasing number of clinical trials that employ the term 'pragmatic' either in their title or abstract (as defined by MEDLINE, but that is not precise nor sensitive). These terms may indicate a greater awareness of pragmatism within abstracts and titles, however it's unclear whether this is reflected in content. Conclusions As appreciation for the value of real-world evidence grows popular, pragmatic trials have gained momentum in research. They are randomized studies that compare real-world alternatives to new treatments that are being developed. They include patient populations that are more similar to those who receive treatment in regular medical care. This approach can overcome the limitations of observational research such as the biases that come with the reliance on volunteers, and the lack of the coding differences in national registry. Other advantages of pragmatic trials include the ability to utilize existing data sources, and a higher chance of detecting meaningful changes than traditional trials. However, these tests could still have limitations which undermine their reliability and generalizability. For example the rates of participation in some trials could be lower than expected due to the healthy-volunteer effect as well as 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 in a timely manner. Additionally, some pragmatic trials do not 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 48 RCTs that self-described themselves as pragmatic and were published until 2022. The PRECIS-2 tool was employed to determine the degree of pragmatism. It covers domains such as eligibility criteria, recruitment flexibility, adherence to intervention, and follow-up. They discovered that 14 of these trials scored pragmatic or highly practical (i.e., scoring 5 or higher) in one or more of these domains, and that the majority were single-center. Trials with a high pragmatism score 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 range of hospitals. The authors claim that these traits can make pragmatic trials more effective and applicable to everyday clinical practice, however they do not necessarily guarantee that a pragmatic trial is free from bias. In addition, the pragmatism that is present in the trial is not a predetermined characteristic; a pragmatic trial that does not have all the characteristics of a explanatory trial can yield valuable and reliable results.
