How to Assess Investigator Skills and Experience
Evaluating investigators for medical device trials requires a focused approach that looks at key skills and experience. It's not enough to check off basic qualifications - investigators need to be equipped to handle the unique demands of medtech research.
Matching Medical Specialties to Trial Needs
An investigator's medical specialty must align with the device being tested and the trial's specific requirements. This includes both their procedural expertise and their experience with the patient population involved. Proper alignment ensures the trial runs smoothly and patients remain safe.
| Assessment Area | Evaluation Criteria | Importance |
|---|---|---|
| Primary Specialty | Matches the device's application | Critical |
| Sub-specialization | Expertise in relevant procedures | High |
| Years in Practice | Active clinical experience | Medium |
| Patient Volume | Regular exposure to target conditions | High |
Hands-on experience with the device being tested is just as important as matching specialties.
Experience with Devices and Related Procedures
Familiarity with the device and related procedures can make a big difference in trial performance. For instance, data from Latin American trials shows that investigators with prior device experience had 27% higher protocol compliance and enrolled participants 35% faster.
When assessing this, look at their history with similar devices, their procedural success rates, and how well they’ve managed any device-related complications.
Academic Background and GCP Certification
While procedural expertise is key, academic training and adherence to Good Clinical Practice (GCP) standards are equally important. These ensure that investigators can meet the scientific and ethical demands of medtech trials. This is especially relevant in regions like Latin America, where medtech trials are growing quickly, and competition is high.
Key qualifications to look for include:
- Research publications
- Previous trial experience
- GCP certification
- Advanced training in emerging medical technologies
Additionally, assess their dedication to staying updated on new technologies and methods. For example, Chile's adoption of virtual monitoring for arrhythmia detection highlights how investigators who combine academic knowledge with practical innovation can drive trial success [1].
Reviewing Research Skills and Site Resources
An investigator's expertise and the site's infrastructure are key to running successful medical device trials. A detailed evaluation of these factors helps anticipate trial outcomes and ensures smooth execution.
Past Performance in Clinical Trials
Key metrics to assess include patient recruitment rates (≥90% of target), protocol compliance (≥95%), data quality (<5% query rate), and retention rates (≥85%). These indicators provide insight into an investigator's ability to succeed in future trials.
| Performance Indicator | Impact on Trial Success |
|---|---|
| Patient Recruitment Rate | Critical |
| Protocol Compliance | High |
| Data Quality | High |
| Retention Rate | Medium |
Site Facilities and Staff Support
Clínica Alemana Vitacura in Chile, featured in Newsweek's World's Best Hospitals 2024, sets a high benchmark for medical device trial facilities [1]. Factors to evaluate include:
- Availability of specialized equipment and proper storage for device trials
- Emergency response readiness for handling adverse events
- Staff qualifications, especially research coordinators experienced in device trials
Access to the Right Patient Population
Understanding the local patient population and having effective recruitment strategies are essential for meeting enrollment goals. Sites with strong patient databases and tested recruitment methods are better positioned for success. Key considerations include:
| Population Factor | Assessment Criteria |
|---|---|
| Patient Demographics and Disease Prevalence | Alignment with trial criteria |
| Geographic Access | Transportation, logistics, and cultural factors |
Data from the National Clinical Trial Registry shows that sites with established patient networks meet recruitment goals 35% faster than those without.
"Evaluating site resources means understanding their ability to support complex device trials while ensuring patient care and data integrity", explains a senior clinical research expert at bioaccess® LATAM MEDTECH CRO.
While research expertise and site resources are crucial, ensuring adherence to ethical and regulatory standards is just as important for trial success.

Ensuring Compliance with Regulations and Ethics
When evaluating investigators, it's essential to focus on their history of meeting regulatory and ethical standards. This ensures both patient safety and the integrity of clinical trials.
Regulatory History and Audit Outcomes
Reviewing an investigator's regulatory history is a key step in assessing their ability to run compliant trials. This includes their adherence to Good Clinical Practice (GCP), outcomes of inspections, and how promptly and accurately they submit reports.
| Assessment Area | Evaluation Criteria | Impact Level |
|---|---|---|
| GCP Compliance | Completeness of documentation, protocol adherence | Critical |
| Inspection History | Findings from FDA or other regulatory bodies, corrective actions taken | High |
| Reporting Timeliness | Meeting deadlines and ensuring accurate submissions | Medium |
In Chile, MINSAL-accredited Research Ethics Committees (RECs) have set stringent standards for investigator evaluations. These efforts contributed to a 249% increase in medical device trials between 2000 and 2017 [2]. While regulatory compliance is essential, ethical standards play an equally important role in ensuring trial success.
Ethical Standards and Conflict of Interest
An investigator's ability to balance regulatory requirements with strong ethical practices is crucial for medtech trials. As more trials are outsourced to emerging markets, maintaining ethical oversight becomes even more critical.
Important ethical considerations include informed consent, managing conflicts of interest, and ensuring patient safety. Investigators must provide:
- Clear and detailed records of informed consent processes
- Systems to manage potential conflicts of interest
- Transparency in financial relationships
- Effective procedures for monitoring patient safety
Electronic tools now allow for real-time tracking of compliance, helping to quickly identify and address issues. This is particularly important in regions like Latin America, where regulatory systems are evolving to align with international expectations.
Steps to Select the Right Investigators
A well-organized process helps ensure investigators are equipped to handle the specific demands of medtech trials, including technical skills and regulatory compliance.
