The Obstetric Anesthesia Research Unit (OARU) is the first research unit in Canada specifically dedicated to the generation of knowledge and the dissemination and transfer of evidence-based clinical practices in obstetrical anesthesia.
OARU was established in 2005 as part of Women’s College Research Institute, under the direction of Dr. Jean Kronberg, former anesthetist-in-chief at Women’s College Hospital. It was founded by clinicians and researchers from the department of anesthesia at Women’s College Hospital and Sunnybrook Health Sciences Centre.
The unit is now affiliated with the University of Toronto and Sunnybrook Research Institute, located at the Bayview Campus of Sunnybrook Health Sciences Centre.
OARU’s mission is threefold:
- to generate high-quality research evidence using appropriate clinical research methodologies;
- to use this knowledge to build models of evidence-based care and transfer this knowledge into clinical practice; and
- to teach research methods/principles of evidence-based medicine as part of building research capacity within obstetric anesthesia.

Projects
Developing a tool to reduce the psychological impact of cesarean sections on women
Urgent and emergency cesarean sections (CS) represent an important source of psychological trauma amongst women and are associated with a fear of future childbirth, postpartum depression, and development of post-traumatic stress disorder (PTSD). An improved understanding of the factors which contribute to a negative birth experience and factors which women find helpful/believe necessary to support them during urgent/emergency CS is required.
Our mixed-methods study explored/described women’s perspectives of urgent/emergency cesarean delivery using qualitative descriptive methods to develop a new Interdisciplinary Patient Support Tool (IPST). The IPST will be used to help guide the supportive care provided by the interdisciplinary team during each stage of cesarean delivery (i.e., immediately preoperatively, during cesarean section, immediately postoperatively).

Novel Diagnostic Pathway for PDPH
Most of the 4.3 million women who give birth in the United States and Canada each year receive epidural analgesia or anesthesia as part of their labor and delivery care. Post-dural puncture headache (“post-epidural PDPH”) represents the most common, important morbidity of epidural needle placement and results from puncture of the spinal sac during epidural needle insertion. However, significant issues exist with diagnosis of PDPH after epidural needle insertions (i.e., “post-epidural PDPH”) which have yet to be formally recognized and addressed. Although formal diagnostic criteria exist for PDPH, these were developed for use after deliberate dural puncture with fine spinal needles and do not account for important differences in epidural needle use and methods of insertion which complicate and confound diagnosis of post-epidural PDPH. New strategies and methods of diagnosis are required to further advance the care of patients with post-epidural PDPH. We are currently developing novel diagnostic tests and a bedside diagnostic pathway for post-epidural PDPH.

Labour Pain Scale
The Angle Labor Pain Questionnaire (A-LPQ) is the first multidimensional psychometric instrument developed specifically to reflect women’s pain experiences during childbirth. Our previous work, which involved three validation studies conducted at Sunnybrook Health Sciences Centre, has demonstrated that the A-LPQ and its five subscales have high levels of internal consistency, test-retest reliability, sensitivity to change and responsiveness during early active labor. Despite this, additional questions remain related to the A-LPQ’s properties and performance which must be addressed.

Research Methods Teaching Series
The Obstetrical Anesthesia Research Unit (OARU) offers formal and informal teaching related to clinical research methodology and clinical appraisal. This is open to anesthesia staff, as well as research and clinical fellows and residents from the University of Toronto during their training. Learning also occurs through participation in OARU’s ongoing research projects. In addition, participants are encouraged to attend formal research rounds organized through the U of T at the Hospital for Sick Children.
As part of this program, OARU provides the opportunity for interdisciplinary learning via the research methods teaching series.
