The quality of patient care was found to be significantly correlated with work environment measures in a quasi-experimental study in the Saskatoon Health Region. Since first line supervisors face multiple pressures in organizing the work of their units, they need to be supported by senior leadership for continuity in instilling a common purpose and shared values to the patient care staff. The role of supervision and leadership is crucial in strategically managing the human, financial and technical resources in our healthcare system, especially when such resources are likely to remain limited.
