About this study
Official title: Study Dynamic Haptic Robotic Trainer (DHRT) and DHRT+ for Central Venous Catheterization Insertion Training for Surgical Residents
Human participants will include medical residents. Each year the entering 1st year medical residents at Hershey Medical Center and Cedars-Sinai Medical Center will be taught to perform these procedures using the DHRT or the DHRT+ devices. The resident's performance will be measured and evaluated by these devices during the training. The technique of the training does not differ from what is currently taught at either of these institutions. In addition the residents will be required to pass the same skills assessment currently required at their institution. Upon successfully passing the skills assessment the residents will perform CVC interventions on under supervision. After the procedure the investigators will examine patient files to determine any changes in central line related complications and infection rates due to new clinical educational practices.
- Conditions
- Central Line Complication, Central Line Infection
- Being tested
- Dynamic Haptic Robotic Trainer (DHRT), Advanced Dynamic Haptic Robotic Trainer (DHRT+)

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Central Line Related Complications due to new Resident Central Line Training Procedures (time frame: baseline (pre-intervention), post-intervention). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jul 2026.
