Research Site Index
249,000+ investigator records scored against your protocol in real time. 186 countries. 228 specialties. Monthly refresh with real-time updates on request. The verified intelligence layer behind AcceleTrial.
What the RSI Is
Most site lists are static, unverified, and protocol-agnostic. The RSI scores every investigator record against your specific protocol parameters: therapeutic area, phase, indication, and patient population. The result is a ranked, ready-to-use site list in minutes, not weeks.
RSI Data Preview
Protocol-Aware Scoring Model
Eight weighted components produce one composite score on a 0 to 10 scale. The weights shift by therapeutic area and trial phase, so the same site is ranked differently for an oncology Phase III than for a dermatology Phase I. The same inputs always produce the same result, and that result powers the ranked site list in AcceleTrial.
Depth of registered trial history, and how the investigator ranks against the full index. The one component available for every record worldwide.
The size of the real patient panel behind the site, from licensed claims and prescribing data. Coverage is strongest in the United States.
Time since the most recent trial on record. Recent work counts for more, and how fast that falls away is tuned by specialty, so a three-year gap reads differently in oncology than in dermatology.
Evidence the investigator already works with industry sponsors. Coverage is strongest in the United States.
The population a study can realistically recruit from around the site's location. Coverage is strongest in the United States.
Regulatory inspection history. A site inspected and cleared scores above one never inspected at all, and an unresolved finding counts heavily against.
Publication record and citation standing for the named investigator. Available globally, not only in the United States.
How quickly the site has historically moved from selection to activation, including its ethics review and contracting model.
Not every signal exists for every investigator. Several components draw on data whose coverage is strongest in the United States, so they are thinner across much of the international index. Rather than scoring a missing signal as zero, which would penalise a site simply for being outside the United States, the engine renormalises across the components it does have and pulls the result toward the index-wide average in proportion to what is missing. A site with thin coverage lands near the middle of the scale, not at the bottom.
What Each Site Record Contains
Full PI and sub-investigator credentials, board certifications, publication history, active trial load, and years of experience by indication.
Historical enrollment rates against projected targets, broken down by phase, indication, and sponsor type across all prior trials.
Regulatory inspection outcomes, audit findings, and protocol deviation history. Every compliance event on record.
Every prior engagement this site has had with sponsors and CROs: contracts executed, performance ratings, and communication history.
Demographic catchment analysis, disease prevalence in the site's geography, and patient pool estimates for specific indications.
IRB turnaround times, contract-to-SIV timelines, and first-patient-in dates from prior trials, giving a predictive view of activation speed.
Therapeutic Coverage
The current RSI runtime exposes 228 normalized specialty options covering virtually all therapeutic areas, with 43,000+ distinct US institution labels and global coverage across 186 countries.
How the RSI Stays Current
Site data decays fast. RSI data is refreshed monthly and can be updated in real-time when requested. Validation-backed source persistence and quality controls keep the intelligence layer current.
RSI data is refreshed on a monthly basis and can be updated in real time when requested by the sponsor or operations team.
Source persistence, shadow validation, and entity-quality workflows maintain trust in the data layer and make the intelligence asset harder to replicate.
Every new sponsor engagement is added to the site record as it concludes, building a longitudinal performance history over time.
