The Benefits & Limitations of RWE
Although RCTs will always have a firm place in healthcare research, RWE can often be used to support existing data and fill any gaps. The benefits of RWE include:
Quick. When compared with RCTs, RWE can be generated very quickly. This means evidence can be kept relevant and updated in response to changes in policy or pathways.
Provides Rich Insights. RWE provides credible insights into the current practices with the health system – this can include safety, efficacy and dosing.
RWE is not always the right method to use to generate data to support your product.
Inconsistencies of electronic data. Not all data is recorded which means the real world data (RWD) is not always representative of the population for which is claims.
Less valid than RCTs. It is subjective what data is included in a RWE study for analysis which means there is a risk of bias.
How Delphi consensus can generate RWE
A highly credible and adaptable way of generating real world evidence in the form of expert opinion is using the Delphi consensus method. The systematic and iterative approach to communication seeks to aggregate opinions from a diverse set of experts to generate clarity and support (evidence) based on collective wisdom. It can be used to help forecast future impact, consolidate a position, or to define policy. The Delphi method is widely adopted and established as a credible research approach that is recognised in the evidence hierarchy. Many treatments or management guidelines have been developed using a version of the Delphi method.
A feature of communication or evidence generated using Triducive’s amplified consensus method is peer-advocacy. Because outputs from Delphi programs are generated by stakeholders who represent an important constituent of the health system itself, they help create social proof for the direction recommended as a result of the work.
Triducive’s amplified Delphi consensus method follows the following steps:
