The STOPIT Group
The STOPIT (Science, Techniques, and Outcomes of Pain assessments and InTerventions) Group
Research Unit Description and Focus
The STOPIT research group, led by Drs. Anuj Bhatia and Philip Peng, based in the Departments of Anesthesia & Pain Medicine at Toronto Western Hospital, Princess Margaret Hospital, Mount Sinai Hospital and Women’s College Hospital. It is comprised of a group of clinicians and researchers (anesthesiologists, pain physicians, anatomists) supported by research staff. Their expertise is over the spectrum of acute, peri-procedural and chronic pain. Research methodologies including proof-of-concept investigations, clinical trials, observational studies, retrospective analyses, systematic reviews, meta-analyses, and population based studies are being used by this group.
Investigational models for therapeutic interventions range from anatomy specimens to subjects with persistent, neuropathic pain. Evaluation of ultrasound against anatomical landmarks and fluoroscopy for interventional pain procedures, predicting and measuring benefit from intravenous ketamine infusions through use of validated questionnaires and functional MRI in refractory neuropathic pain, and ascertaining benefit from spinal interventions through synthesis of available evidence are some of the current research foci. Both Dr Bhatia and Dr Peng have published several manuscripts, book chapters, and books on assessment and treatment of pain. They also organize several workshops and academic events to increase awareness of recent advances in treatment of pain.
