Brief Biography

Dr. Mahant completed his MD at The University of Toronto in 1995 and postgraduate training in pediatrics at The Hospital for Sick Children (SickKids) in 1999. Mahant was appointed on staff in the Division of Paediatric Medicine in 1999; completed an M.Sc in Health Research Methods (Clinical Epidemiology) in 2010 at McMaster University; and was appointed Associate Professor in 2011.

Academic Background

Education Leadership

Sanjay is the Associate Program Director for the Academic General Pediatrics Fellowship.

Clinical Care Activities

Sanjay is attends on the Pediatric Medicine Inpatient Unit.  He attends in the Ambulatory Complex Care Program and Enterostomy Tube feeding clinic.

Research Interests

Broadly, Mahant's research program centres on outcomes research in childhood hospital care. Outcomes research is scientific investigation that generates knowledge to guide health-care decisions and promote optimal results from preventive, diagnostic, prognostic, and therapeutic health care strategies. It “derives directly from real world practice and policy...and seeks to increase the likelihood that patients achieve the outcomes they desire through better information, better decisions, and better health-care delivery (Krumholz JAMA 2011).”

My research program involves questions in the three major domains:

1. Comparative effectiveness of clinical strategies in real world settings. Which diagnostic, treatment, or health care delivery strategies are most effective?
2. The perspective of the patient. How can we promote the alignment of health care decisions with patient preference and goals?
3. Health-care systems performance. How are health systems performing around effectiveness, efficiency, equity, safety, patient-centeredness and timeliness of care? How can we optimally implement strategies to improve outcomes?  

Specific areas of research focus within these domains include:

1. Comparative effectiveness: Highly prevalent, and cumulatively costly conditions in childhood hospital care. Mahant has published research addressing diagnosis, prognosis and therapy for prevalent and cumulatively costly conditions (e.g. pneumonia, UTI, bronchiolitis) seen in Pediatric Hospital medicine in high impact general paediatric journals. I am principal investigator on a CIHR funded multi-centre trial comparing oxygen monitoring strategies for hospitalized children with bronchiolitis.

2. The perspective of the patient: Shared-decision making around tube feeding in children with neurologic disabilities. My research in this area has focused on a common health issue affecting children with neurologic disabilities: swallowing dysfunction and undernutrition. Mahant has led research which has evaluated the impact of feeding interventions, specifically gastrostomy tube feeding. This research has evaluated health related quality of life and patient preferences and values around this intervention in order to inform how we can make better decisions with families.

3. Health-care systems performance: childhood hospital care. Mahant has led and collaborated on research examining the quality of care for hospitalized children. I have shown the effectiveness of audit and feedback to reduce inappropriate hospital use. He was a co-investigator on a PRIS network study that showed how to improve physician-to-physician communication in the hospital setting in order to reduce medical error. He also collaborated with US colleagues on evaluating hospital performance for a variety of conditions such as bronchiolitis, diabetic ketoacidosis, pneumonia and complex diseases using routinely collected data. Mahant has led a series of studies evaluating the performance of US children’s hospitals around tonsillectomy, one of the most common and cumulatively expensive surgeries in hospital care. These studies have examined process and outcome measures in a large cohort of children (n=130,000) across 32 hospitals and have informed quality of care measurement and hospital policies.

He is involved in the development and advancement of research networks within the field of general paediatrics and hospital medicine. Mahant is an executive council member for the Pediatric Research in Inpatient Network PRIS. He is also leading the development of a Canadian Pediatric Medicine inpatient research network focusing on highly prevalent, cumulatively expensive conditions. Mahant is on the editorial board of The Journal of Pediatrics. He has previously served as the President of the Hospital Pediatrics Section, Canadian Pediatrics Society.
