At Mautalen we achieve fast and efficient recruitment mainly through our 25.000 patient database, forthcoming patients and referrals. We consistently achieve and improve the recruitment projections committed during the feasibility process.

We place special attention in selecting suitable patients to achieve the lowest possible screening failure ratio for our clients.

We have recruited more than 5000 patients for different Studies in the last years.


Through our Clinical Operations Management, in charge of Quality Assurance, we guarantee that all clinical trial activities comply with GCP standards, local regulations, ethic requirements and protocol designs. Among its main responsibilities, it is in charge of preparing the site for audits and inspections, and of overseeing the submission of documents to the Ethics Committee and to the Regulatory Agencies. It is also responsible for the supervising the training operations.
By means of this program we have successfully gone through FDA Audit and EMEA audits with no actions indicated and through several Quality Assurance Audits from different clients as well.
Our operations staff performance is measured by several Key Performance Indicators (KPI). KPI have demonstrated to be a valuable tool to induce staff behavior in achieving high standard quality results.

We are committed to achieve the highest level of patient care and patient safety. All the staff is trained to give a kind, comprehensive and professional care to meet high standards in patient retention. At this moment, we have an average of 88.6% of patient adherence at the end of the first year or end of the trial. This shows an excellent compliance ratio with treatments.


We are committed as well to deliver clean and consistent on Schedule data, using Electronic CRF.
It is not easy to obtain and interpret quantitative measures of data quality due to the variety of CRFs and monitoring methods in use. However we have found that a good indicator is the data query rate. Basing on the KPI of the data entry staff, we can state that we have an average ratio of 4 queries per patient, which are solved within 4 days. We achieve this level of quality by providing ongoing training to the staff members, by the client´s feedback, and by auditing our own procedures


Staff Performance impacts on our client´s satisfaction and data delivery. All new staff is given a comprehensive induction. Their needs on individual training are assessed and the required training is provided on an ongoing basis.

Courses include:
- Good Clinical Practicesv - Local regulations
- Specific procedures to conduct clinical trials: CRF completion, source data completion, CRF query resolutions, drug accountability records and site files
- Site initiations, attended by each trial staff
- SOP training (Standard Operating Procedures)
- Therapeutic areas training – dedicated to specific Studies
- IATA training for lab technicians
