Pragmatic Free Trial Meta
Pragmatic Free Trial Meta is a non-commercial, open data platform and infrastructure that supports research on pragmatic trials. It collects and shares cleaned trial data and ratings using PRECIS-2 which allows for multiple and varied meta-epidemiological studies to examine the effects of treatment across trials that have different levels of pragmatism and other design features.
Background
Pragmatic trials provide real-world evidence that can be used to make clinical decisions. However, the usage of the term "pragmatic" is not uniform and its definition and evaluation requires clarification. Pragmatic trials should be designed to inform clinical practice and policy decisions, not to confirm an hypothesis that is based on a clinical or physiological basis. A pragmatic trial should aim to be as similar to real-world clinical practice as possible, such as the recruitment of participants, setting and design of the intervention, its delivery and implementation of the intervention, and the determination and analysis of the outcomes, and primary analyses. This is a significant difference between explanation-based trials, as defined by Schwartz and Lellouch1 that are designed to prove the hypothesis in a more thorough way.
Studies that are truly pragmatic must be careful not to blind patients or clinicians in order to cause distortions in estimates of the effect of treatment. Pragmatic trials should also seek to attract patients from a variety of health care settings, to ensure that the results can be applied to the real world.
Furthermore, trials that are pragmatic must focus on outcomes that matter to patients, such as the quality of life and 프라그마틱 홈페이지 functional recovery. This is especially important when trials involve the use of invasive procedures or could have harmful adverse consequences. The CRASH trial29, for instance, focused on functional outcomes to evaluate a two-page case report with an electronic system to monitor the health of patients in hospitals suffering from chronic heart failure. In addition, the catheter trial28 focused on urinary tract infections that are symptomatic of catheters as the primary outcome.
In addition to these features the pragmatic trial should also reduce the procedures for conducting trials and requirements for data collection to reduce costs. Finally pragmatic trials should strive to make their results as relevant to actual clinical practice as they can by making sure that their primary analysis is the intention-to-treat approach (as described in CONSORT extensions for pragmatic trials).
Despite these criteria, 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 about pragmatism, and the usage of the term should be standardised. The creation of a PRECIS-2 tool that offers a standardized objective evaluation of the pragmatic characteristics is a first step.
Methods
In a practical study it is the intention to inform clinical or policy decisions by showing how an intervention could alanced comparisons and lower statistical power, which increases the risk of either not detecting or misinterpreting differences in the primary outcome. This was a problem in the meta-analysis of pragmatic trials because secondary outcomes were not adjusted for differences in covariates at the time of baseline.
Additionally, studies that are pragmatic can pose difficulties in the collection and interpretation of safety data. It is because adverse events are usually self-reported and are susceptible to errors, delays or 프라그마틱 슬롯 추천 coding errors. It is therefore crucial to enhance the quality of outcomes ascertainment in these trials, in particular by using national registries instead of relying on participants to report adverse events in the trial's database.
Results
While the definition of pragmatism does not mean that trials must be 100% pragmatic, there are benefits to incorporating pragmatic components into clinical trials. These include:
By incorporating routine patients, the results of trials can be translated more quickly into clinical practice. However, pragmatic trials can also have drawbacks. The right amount of heterogeneity, for example could help a study generalise its findings to many different settings or patients. However the wrong type of heterogeneity could reduce the sensitivity of an assay and, consequently, lessen the power of a trial to detect minor treatment effects.
A variety of studies have attempted to categorize pragmatic trials, using various definitions and scoring systems. Schwartz and Lellouch1 created a framework for distinguishing between research studies that prove the clinical or physiological hypothesis and pragmatic trials that inform the selection of appropriate treatments in the real-world clinical setting. The framework consisted of nine domains that were assessed on a scale of 1-5 which indicated that 1 was more informative and 5 being more pragmatic. The domains included recruitment, setting, intervention delivery, flexible adherence, follow-up and 프라그마틱 슬롯 추천 primary analysis.
The original PRECIS tool3 was based on a similar scale and domains. 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 reviews scored higher on average in most domains, but scored lower in the primary analysis domain.
This distinction in the primary analysis domains can be explained by the way most pragmatic trials analyze data. Some explanatory trials, however, do not. The overall score for pragmatic systematic reviews was lower when the domains of management, 프라그마틱 슬롯 추천 flexible delivery and following-up were combined.
It is important to remember that a study that is pragmatic does not necessarily mean a low-quality study. In fact, there is an increasing number of clinical trials that use the term "pragmatic" either in their abstracts or titles (as defined by MEDLINE, but that is neither sensitive nor precise). These terms may signal a greater appreciation of pragmatism in titles and abstracts, but it isn't clear if this is reflected in the content.
Conclusions
In recent years, pragmatic trials are becoming more popular in research as the value of real-world evidence is increasingly recognized. They are randomized clinical trials that compare real-world care alternatives rather than experimental treatments under development, they involve patients which are more closely resembling the patients who receive routine medical care, they utilize comparisons that are commonplace in practice (e.g., existing drugs) and depend on the self-reporting of participants about 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 the coding differences in national registry.
Other advantages of pragmatic trials include the ability to use existing data sources, and a higher likelihood of detecting meaningful changes than traditional trials. However, these trials could have some limitations that limit their credibility and generalizability. For example the participation rates in certain trials might be lower than anticipated due to the healthy-volunteer effect and financial incentives or competition for participants from other research studies (e.g., industry trials). The necessity to recruit people in a timely fashion also restricts the sample size and the impact of many pragmatic trials. Practical trials aren't always equipped with controls to ensure that any observed differences aren't caused by biases that occur during the trial.
The authors of the Pragmatic Free Trial Meta identified 48 RCTs self-labeled as pragmatist and published until 2022. They assessed pragmatism by using the PRECIS-2 tool, which consists of the domains eligibility criteria and recruitment criteria, as well as flexibility in adherence to intervention and follow-up. They discovered that 14 trials scored highly pragmatic or pragmatic (i.e. scoring 5 or above) in at least one of these domains.
Trials with a high pragmatism score tend to have higher eligibility criteria than traditional RCTs which have very specific criteria that are unlikely to be found in clinical practice, and they include populations from a wide variety of hospitals. According to the authors, can make pragmatic trials more relevant and useful in everyday practice. However, they cannot guarantee that a trial will be free of bias. Furthermore, the pragmatism of trials is not a predetermined characteristic and a pragmatic trial that doesn't have all the characteristics of an explanatory trial can produce valuable and reliable results.
