Patient Satisfaction Ratings

Patient Rating Breakdown

The Patient Satisfaction Rating is an average of all responses to the care provider related questions shown below from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.

Responses are measured on a scale of 1 to 5 with 5 being the best score.

Comments are submitted by patients and reflect their views and opinions. The comments are not endorsed by and do not necessarily reflect the views of Penn Medicine.

Research

Description of Research Expertise:

Clinical/translational research focuses on peripheral nerve repair and regeneration, as well as a variety of projects in cerebrovascular surgery. Collaborative research includes evaluation of safety and efficacy of xenon-CT for cerebral blood flow monitoring in subarachnoid hemorrhage and trauma; evaluation of a noninvasive near-infrared spectroscopy device for detection of intracerebral hematomas; evaluation of brain oxygen tension monitoring in subarachnoid hemorrhage; arterial spin-labelling MR in AVM shunt visualization; MRI evaluation of carotid plaques and hemispheric blood flow before and after carotid endarterectomy; cost-effectiveness analysis of imaging in carotid endarterectomy and cerebral aneurysm repair; clinical outcomes for surgical treatment of patients with intractable occipital neuralgia.
