The Hamilton Health Sciences (HHS) Anesthesia Department is a tertiary care academic department composed of four sites and a multidisciplinary pain clinic. Each site has its unique composition of perioperative, pain, and critical care services, offering a valuable clinical and academic experience for undergraduate and postgraduate learners, practicing anesthesiologists, and pain practitioners. The four sites include: the Hamilton General Hospital (HGH), the Juravinski Hospital (JH), McMaster University Medical Centre (MUMC), and West Lincoln Memorial Hospital (WLMH). The DeGroote Pain Clinic is also part of the Department of Anesthesia.

Hamilton Health Sciences' Anesthesia Department has 65 anesthesiologists, all of whom balance clinical and academic work. Twenty-four thousand operative procedures were completed in 2015, with each of the last five years having comparable numbers. There are 18 geographical full-time equivalents (GFTs), though all anesthesiologists have academic appointments and engage in clinical teaching of medical students and residents. Many contribute in the formal teaching program of both undergraduate and postgraduate medicine. HHS clinical educators, site leaders, subspecialty leaders, and others ensure we maximize educational and clinical experience opportunities. In addition, HHS anesthesiologists are active clinician researchers. It is notable that HHS anesthesiologists are part of multidisciplinary and multi-site research trials with publications in reputable clinical and scientific journals with high-impact factors. These are clinician researchers with full-time clinical practices who still contribute significantly to the research literature and impact upon best practices in anesthesia in perioperative care.

Three of the sites are situated in Hamilton within a short driving distance of each other. Most clinicians work at two of the three sites, while some work at all three sites, according to their subspecialty areas of interest and practice. Residents are generally assigned to services according to site, allowing for focused learning in a familiar environment with consistent teaching, supervision, and feedback.
