Background: Little is known about the existing structure and function of referral networks in the prevalent referral system for specialized surgical care in Canada, which is based on direct physician referral to specialists in a largely unmanaged referral marketplace. Our objective was to describe and analyze the referral networks of referring physicians and surgeons for common surgical procedures in Ontario, to better understand potential barriers to single-entry models.

Methods: We analyzed referral networks for patients between referring physicians and surgeons for 9 common scheduled surgical procedures from 2016 to 2019 using administrative data sources in Ontario.

Background: Canadian health systems fare poorly in providing timely access to elective surgical care, which is crucial for quality, trust, and satisfaction.

Methods: We conducted a cross-sectional analysis of surgical wait times for adults receiving non-urgent cataract surgery, knee arthroplasty, hip arthroplasty, gallbladder surgery, and non-cancer uterine surgery in Ontario, Canada, between 2013 and 2019. We obtained data from the Wait Times Information System (WTIS) database.

Background: Cancer surgery cancellation can have negative consequences for the patient, the surgeon and the health care system. There is a paucity of literature on cancer surgery cancellation and its association with wait times, perioperative outcomes, survival and costs of care. Therefore, the objective of this study was to determine the incidence of same-day cancer surgery cancellation in a universal health care context and its association with short and long-term outcomes.

Background: To mitigate the effects of coronavirus disease 2019 (COVID-19), jurisdictions worldwide ramped down nonemergent surgeries, creating a global surgical backlog. We sought to estimate the size of the nonemergent surgical backlog during COVID-19 in Ontario, Canada, and the time and resources required to clear the backlog.

Methods: We used 6 Ontario or Canadian population administrative sources to obtain data covering part or all of the period between Jan.

In 2009, the Ontario Ministry of Health and Long-Term Care engaged Cancer Care Ontario to expand the Wait Time Information System to capture surgical consultation data (Wait 1). Over the years, an increasing number of patient and provider reports have shown that Wait 1 wait times account for a significant portion of the total wait time for surgery. With data published online by the ministry in late summer 2017, patients were given access to consultation wait time information for over 200 types of procedures at 92 surgical facilities in Ontario.

The shift towards patient-centred care is the priority in health care today. Providing quality care that is highly efficient and patient-friendly while also being cost-effective is a difficult, but not impossible task.
