Pragmatic Free Trial Meta Pragmatic Free Trail Meta is an open data platform that enables research into pragmatic trials. It collects and distributes clean trial data, ratings and evaluations using PRECIS-2. This allows for diverse meta-epidemiological studies to evaluate the effects of treatment across trials of various 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 not uniform and its definition and assessment requires 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 trial should try to be as close as is possible to real-world clinical practices which include the recruitment of participants, setting up, delivery and implementation of interventions, determining and analysis outcomes, and primary analyses. This is a key distinction from explanation trials (as described by Schwartz and Lellouch1) which are designed to provide more complete confirmation of the hypothesis. The trials that are truly practical should be careful not to blind patients or the clinicians in order to result in bias in estimates of treatment effects. Practical trials should also aim to recruit patients from a variety of health care settings, to ensure that their findings are generalizable to the real world. Finally, pragmatic trials should focus on outcomes that are vital to patients, like quality of life or functional recovery. This is particularly relevant when it comes to trials that involve the use of invasive procedures or potential for dangerous adverse events. The CRASH trial29, for instance focused on the functional outcome to compare a two-page report with an electronic system to monitor the health of hospitalized patients with chronic heart failure. Similarly, the catheter trial28 focused on urinary tract infections caused by catheters as the primary outcome. In addition to these features pragmatic trials should reduce the procedures for conducting trials and requirements for data collection to reduce costs. Additionally pragmatic trials should try to make their findings as relevant to actual clinical practice as is possible by ensuring that their primary analysis is based on the intention-to-treat method (as described in CONSORT extensions for pragmatic trials). Despite these criteria, many 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 false claims of pragmatism and the use of the term needs to be standardized. The creation of a PRECIS-2 tool that can provide a standardized objective evaluation of pragmatic aspects is a first step. Methods In a practical trial the goal is to inform clinical or policy decisions by demonstrating how an intervention would be implemented into routine care. This differs from explanation trials that test hypotheses regarding the causal-effect relationship in idealized settings. In this way, pragmatic trials may have a lower internal validity than studies that explain and be more susceptible to biases in their design, analysis, and conduct. Despite these limitations, pragmatic trials can be a valuable source of information for decisions in the context of healthcare. The PRECIS-2 tool evaluates an RCT on 9 domains, ranging between 1 and 5 (very pragmatist). In this study the areas of recruitment, organisation, flexibility in delivery, flexible adherence and follow-up received high scores. However, the main outcome and the method of missing data were scored below the practical limit. This suggests that it is possible to design a trial that has high-quality pragmatic features, without damaging the quality of its outcomes. It is difficult to determine the level of pragmatism in a particular study because pragmatism is not a possess a specific characteristic. Some aspects of a study can be more pragmatic than others. Moreover, protocol or logistic modifications during the course of an experiment can alter its score in pragmatism. Additionally, 36% of the 89 pragmatic trials identified by Koppenaal et al were placebo-controlled or conducted before licensing, and the majority were single-center. They are not close to the norm, and can only be considered pragmatic if the sponsors agree that such trials are not blinded. Furthermore, a common feature of pragmatic trials is that researchers try to make their results more meaningful by analysing subgroups of the trial. However, this can lead to unbalanced comparisons and lower statistical power, thereby increasing the risk of either not detecting or incorrectly detecting differences in the primary outcome. In the case of the pragmatic trials included in this meta-analysis this was a serious issue because the secondary outcomes were not adjusted to account for the differences in baseline covariates. Additionally practical trials can present challenges in the collection and interpretation of safety data. This is due to the fact that adverse events are typically reported by participants themselves and prone to delays in reporting, inaccuracies, or coding variations. It is important to improve the quality and accuracy of outcomes in these trials. Results Although the definition of pragmatism doesn't require that all clinical trials are 100% pragmatic, there are benefits when incorporating pragmatic components into trials. These include: Enhancing sensitivity to issues in the real world which reduces study size and cost as well as allowing trial results to be faster translated into actual clinical practice (by including patients from routine care). However, pragmatic studies can also have drawbacks. The right type of heterogeneity, for example could allow a study to generalise its findings to many different settings or patients. However, the wrong type can reduce the assay sensitivity, and therefore reduce a trial's power to detect minor treatment effects. Many studies have attempted categorize pragmatic trials using various definitions and scoring methods. Schwartz and Lellouch1 have developed a framework that can differentiate between explanation studies that prove the physiological hypothesis or clinical hypothesis, and pragmatic studies that help inform the selection of appropriate treatments in clinical practice. The framework was composed of nine domains scored on a 1-5 scale which indicated that 1 was more explanatory while 5 was more pragmatic. The domains covered recruitment, setting up, delivery of intervention, flexible adherence and primary analysis. The original PRECIS tool3 was an adapted version of the PRECIS tool3 that was based on the same scale and domains. Koppenaal et. al10 devised an adaptation of the assessment, dubbed the Pragmascope, that was easier to use for systematic reviews. They discovered that pragmatic reviews scored higher on average in all domains, but scored lower in the primary analysis domain. The difference in the primary analysis domain can be explained by the way that most pragmatic trials analyse data. Some explanatory trials, however don't. The overall score for pragmatic systematic reviews was lower when the areas of management, flexible delivery and following-up were combined. It is important to remember that a pragmatic trial does not necessarily mean a low-quality trial, and there is an increasing number of clinical trials (as defined by MEDLINE search, but it is neither sensitive nor specific) that use the term “pragmatic” in their abstracts or titles. These terms may signal an increased understanding of pragmatism in titles and abstracts, but it isn't clear if this is reflected in content. Conclusions In recent years, pragmatic trials are increasing in popularity in research because the value of real-world evidence is becoming increasingly acknowledged. They are randomized trials that evaluate real-world alternatives to new treatments that are being developed. They are conducted with populations of patients more closely resembling those treated in regular care. This method has the potential to overcome the limitations of observational studies that are prone to biases associated with reliance on volunteers and limited availability and the variability of coding in national registry systems. Pragmatic trials have other advantages, like the ability to draw on existing data sources and a higher chance of detecting significant differences than traditional trials. However, these trials could be prone to limitations that compromise their credibility and generalizability. For instance the rates of participation in some trials may be lower than expected due to the healthy-volunteer influence and incentives to pay or compete for participants from other research studies (e.g., industry trials). The necessity to recruit people in a timely manner also restricts the sample size and the impact of many pragmatic trials. Additionally some pragmatic trials do not have controls to ensure that the observed differences aren't due to biases in trial conduct. The authors of the Pragmatic Free Trial Meta identified 48 RCTs self-labeled as pragmatic and were published up to 2022. The PRECIS-2 tool was used to assess the degree of pragmatism. It includes domains such as eligibility criteria, recruitment flexibility and adherence to intervention and follow-up. They discovered 14 trials scored highly pragmatic or pragmatic (i.e. scoring 5 or above) in at least one of these domains. Trials that have high pragmatism scores tend to have broader criteria for eligibility than conventional RCTs. They also contain patients from a variety of hospitals. According to the authors, may make pragmatic trials more relevant and relevant to everyday practice. However they do not ensure that a study is free of bias. Furthermore, the pragmatism of the trial is not a definite characteristic; a pragmatic trial that does not possess all the characteristics of a explanatory trial can produce valid and useful results.
