Although geared towards a common goal - improved patient-centred care - quality improvement strategies and patient engagement-focused approaches are often developed and conducted in silos. The lack of integration may lead, on the one hand, to the uptake of patient suggestions that do not always take into consideration implications for the delivery of quality care and, on the other hand, to inadequate understanding of patient views required to create optimal services. The Children's Hospital of Eastern Ontario (CHEO)'s action plans to address gaps in patient engagement and quality improvement, two of its priority areas, were initially carried out in isolation of each other...

Effective patient relations are important to improve patient experience and deliver better care. Policy and legislative changes in Ontario have increased accountabilities for patient relations and expanded Health Quality Ontario (HQO)'s mandate. In response, HQO collaborated with patients, health sector organizations, associations and the Ministry of Health and Long-Term Care to co-design a patient relations measurement and reporting approach. Informed by an environmental scan, broad consultations, a multi-sector survey and a provincial advisory group, the approach includes standardized patient relations indicators to support measurement and public reporting across the hospital, home and long-term care sectors...

About 1-2/1000 of postpartum women require psychiatric admission. Length of stay is variable, and little is known about short postpartum admission. From all women in Ontario, Canada, with a psychiatric admission within 1 year postpartum (2007-2012) (n = 1702), we compared women with admissions <72 h to women with longer admissions on sociodemographics, clinical characteristics and post-discharge mental health service use. About 37% of admissions were <72 h. These women were more likely to be adolescents (11...

Wetlands in the region of Southern Ontario, Canada have declined substantially from their historic area. Existing regulations and programs have not abated this decline. However, reversing this trend by protecting or restoring wetlands will increase the supply of important ecosystem services. In particular, these actions will contribute to moderating the impacts of extreme weather predicted to result from climate change as well as reducing phosphorous loads in Lake Erie and ensuing eutrophication. Since the majority of land in the region is privately owned, landowners can play an important role...
