Pragmatic Free Trial Meta
Pragmatic Free Trail Meta is an open data platform that enables research into pragmatic trials. It collects and distributes cleaned trial data, ratings and evaluations using PRECIS-2. This allows for a variety of meta-epidemiological analyses that evaluate the effects of treatment across trials of various levels of pragmatism.
Background
Pragmatic studies are increasingly recognized as providing real-world evidence for clinical decision-making. The term "pragmatic" however, is not used in a consistent manner and its definition and assessment require further clarification. Pragmatic trials must be designed to guide clinical practice and policy decisions, not to confirm the validity of a clinical or physiological hypothesis. A pragmatic trial should try to be as close as is possible to actual clinical practices which include the recruitment of participants, setting, designing, delivery and implementation of interventions, determining and analysis results, as well as primary analyses. This is a significant difference between explanatory trials as described by Schwartz & Lellouch1 that are designed to test a hypothesis in a more thorough way.
Truely pragmatic trials should not conceal participants or the clinicians. This can lead to bias in the estimations of treatment effects. The trials that are pragmatic should also try to attract patients from a wide range of health care settings, so that their results are generalizable to the real world.
Additionally studies that are pragmatic should focus on outcomes that are crucial for patients, such as quality of life or functional recovery. This is especially important for trials involving surgical procedures that are invasive or have potential dangerous adverse events. The CRASH trial29 compared a 2-page report with an electronic monitoring system for patients in hospitals suffering from chronic cardiac failure. The catheter trial28 on the other hand utilized symptomatic catheter-related urinary tract infection as its primary outcome.
In addition to these aspects pragmatic trials should also reduce the requirements for data collection and trial procedures to cut costs and time commitments. Furthermore pragmatic trials should try to make their findings as applicable to real-world 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 guidelines however, a large number of 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 misleading claims of pragmatism, and the term's use should be standardized. The development of the PRECIS-2 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 policy or clinical decisions by showing how an intervention can be integrated into routine care in real-world situations. This differs from explanation trials, which test hypotheses about the cause-effect relationship in idealised settings. In this way, pragmatic trials could have lower internal validity than explanation studies and be more prone to biases in their design, analysis, and conduct. Despite these limitations, pragmatic trials can contribute valuable information to decision-making in the context of healthcare.
The PRECIS-2 tool measures the degree of pragmatism in an RCT by assessing it on 9 domains ranging from 1 (very explicative) to 5 (very pragmatic). In this study, the areas of recruitment, organisation and flexibility in delivery, 프라그마틱 무료 슬롯 프라그마틱 무료 슬롯체험 [www.diggerslist.com says] flexibility in adherence, and follow-up were awarded high scores. However, the main outcome and method of missing data were scored below the practical limit. This suggests that a trial could be designed with good practical features, yet not damaging the quality.
It is difficult to determine the amount of pragmatism that is present in a trial because pragmatism does not have a binary characteristic. Some aspects of a study can be more pragmatic than others. Furthermore, logistical or protocol modifications during the course of the trial may alter its pragmatism score. Additionally 36% of 89 pragmatic trials identified by Koppenaal and co. were placebo-controlled, or conducted prior to licensing and most were single-center. Thus, they are not as common and can only be described as pragmatic if their sponsors are tolerant of the lack of blinding in such trials.
A common feature of pragmatic studies is that researchers attempt to make their findings more relevant by studying subgroups of the trial sample. However, this often leads to unbalanced results and lower statistical power, which increases the likelihood of missing or incorrectly detecting differences in the primary outcome. This was the case in the meta-analysis of pragmatic trials because secondary outcomes were not adjusted for covariates that differed at the baseline.
Additionally, pragmatic trials can also have challenges with respect to the collection and interpretation of safety data. This is due to the fact that adverse events are typically self-reported and are susceptible to errors, delays or coding differences. Therefore, it is crucial to improve the quality of outcomes ascertainment in these trials, and ideally by using national registries rather than relying on participants to report adverse events on the trial's own database.
Results
While the definition of pragmatism may not require that clinical trials be 100% pragmatic there are benefits when incorporating pragmatic components into trials. These include:
Incorporating routine patients, the results of the trial can be more quickly translated into clinical practice. But pragmatic trials can have their disadvantages. The right amount of heterogeneity, for example could help a study extend its findings to different settings or patients. However, the wrong type can decrease the sensitivity of the test and thus lessen the power of a trial to detect even minor effects of treatment.
Many studies have attempted categorize pragmatic trials using various definitions and scoring methods. Schwartz and Lellouch1 developed a framework to distinguish between explanatory trials that confirm a physiological or clinical hypothesis, and pragmatic trials that aid in the choice of appropriate therapies in clinical practice. Their framework included nine domains, each scored on a scale of 1 to 5, with 1 indicating more lucid and 5 indicating more practical. The domains were recruitment, setting, intervention delivery, flexible adherence, follow-up and primary analysis.
The original PRECIS tool3 was based on a similar scale and domains. Koppenaal and colleagues10 created an adaptation of this assessment, known as the Pragmascope, that was easier to use for systematic reviews. They found that pragmatic systematic reviews had a higher average scores across all domains, but lower scores in the primary analysis domain.
This difference in the analysis domain that is primary could be explained by the fact that most pragmatic trials process their data in an intention to treat method while some explanation trials do not. The overall score was lower for systematic reviews that were pragmatic when the domains of organisation, flexible delivery, and follow-up were combined.
It is important to remember that a pragmatic trial doesn't necessarily mean a poor quality trial, and indeed there is an increasing number of clinical trials (as defined by MEDLINE search, but this is neither specific nor sensitive) which use the word "pragmatic" in their abstract or title. The use of these terms in abstracts and titles could suggest a greater awareness of the importance of pragmatism, however, it is not clear if this is evident in the content of the articles.
Conclusions
In recent years, pragmatic trials have been gaining popularity in research as the value of real world evidence is increasingly recognized. They are clinical trials that are randomized which compare real-world treatment options instead of experimental treatments under development. They have populations of patients that more closely mirror the ones who are treated in routine medical care, they utilize comparisons that are commonplace in practice (e.g., existing drugs), and they rely on participant self-report of outcomes. This method can help overcome the limitations of observational studies which include the limitations of relying on volunteers and limited accessibility and coding flexibility in national registries.
Other advantages of pragmatic trials include the ability to use existing data sources, as well as a higher likelihood of detecting meaningful changes than traditional trials. However, pragmatic trials may be prone to limitations that compromise their reliability and generalizability. For instance the rates of participation in some trials could be lower than expected due to the healthy-volunteer effect as well as incentives to pay or compete for participants from other research studies (e.g. industry trials). Many pragmatic trials are also restricted by the necessity to recruit participants in a timely manner. In addition some pragmatic trials don't 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 RCTs published up to 2022 that self-described as pragmatism. The PRECIS-2 tool was employed to assess the pragmatism of these trials. It covers areas such as eligibility criteria, recruitment flexibility as well as adherence to interventions and follow-up. They discovered that 14 of the trials scored as highly or pragmatic practical (i.e. scoring 5 or more) in one or more of these domains and that the majority of them were single-center.
Studies that have high pragmatism scores tend to have more criteria for eligibility than traditional RCTs. They also include patients from a variety of hospitals. According to the authors, could make pragmatic trials more useful and 프라그마틱 applicable in everyday clinical. However, they cannot guarantee that a trial will be free of bias. The pragmatism characteristic is not a fixed attribute; a pragmatic test that does not possess all the characteristics of an explanatory study can still produce reliable and beneficial results.
