Understanding feasibility for faster clinical trials
Friday, January 1, 2016
Do you hate to be late? Most people do, but CenterWatch surveys of investigative sites show the majority have delays. A root cause is increasing eligibility criteria (up 58% in the last decade). It is no wonder that sites say recruitment is the biggest cause of delay; with more criteria, fewer patients qualify.
The fastest and most efficient sponsors are simplifying design procedures to reduce protocol complexity. One way to better study feasibility is to understand patient availability for the inclusion/exclusion criteria. Sponsors attempt to do so with questionnaires sent to sites. Unfortunately, answers can be inaccurate. A better solution is to base feasibility on national patient counts; the databases are from insurance claims and electronic health records (EHR).
Insurance claims and EHR databases can identify how many patients exist. The databases begin with a de-identified sample of patients who have the targeted condition; they show the percentage of patients lost for each specification. For instance, according to Optum insurance-claims data, a sponsor would exclude 76% of adult diabetics from a trial if it excluded all forms of hypertension. The sponsor can then determine if that percentage is too high. EHR can assess things in a medical record not found in claims. Next, this method shows the net percentage of patients who meet all criteria; it therefore predicts if recruitment will be easy or hard, making it possible to plan resources.
An added benefit of insurance claims is that the information can be used to locate patients—or “fish where the fish are.” Claims can rank physicians and investigators on patient count. (See more in my Action Items article planned for April.)
Does your company embrace quantitative methods when determining feasibility and site identification? If not, these approaches are the wave of the future, and the future is now.
