This initiative will focus solely on the nurse subgroup and concerns schedule optimization to ensure the presence of the appropriate number of nurses per shift, thereby reducing stress, burnout and limiting the need for overtime.

Metrics for evaluation concerning patient outcomes include measurement of the quality of care perceived by patients and their families. Data used for this analysis will be collected from TOH Data Warehouse and Montfort's Department of Archives and Decision Support.

Metrics for evaluation concerning ICU medical procedures specifically targeted in the educational intervention component include the rate of albumin used per ICU admission (bags of albumin used/admission). Patient data used for this analysis will be collected from TOH Data Warehouse and Montfort's Department of Archives and Decision Support.

Metrics for evaluation concerning ICU medical procedures specifically targeted in the educational intervention component include the number of patients mechanically ventilated, and the duration of their ventilation in days. Patient data used for this analysis will be collected from TOH Data Warehouse and Montfort's Department of Archives and Decision Support.

Metrics for evaluation concerning ICU medical procedures specifically targeted in the educational intervention component include the number of ICU patient chest radiographs completed per day. Patient data used for this analysis will be collected from TOH Data Warehouse and Montfort's Department of Archives and Decision Support.

Metrics for evaluation concerning ICU medical procedures specifically targeted in the educational intervention component include the rate of red blood cell transfusions per admission. The amount of red blood cell transfusions administered (measured in bags/admission) will be monitored throughout ICU admission. Patient data used for this analysis will be collected from TOH Data Warehouse and Montfort's Department of Archives and Decision Support.

We will collect data on ICU full-time staff absenteeism during the study period from the Data Warehouse and Montfort Archives.

8-15 ICU stakeholder staff with special knowledge of ICU activities will be recruited for post-interventional interviews. The semi-structured interviews will be conducted by trained research staff and will use the Post-Intervention Semi-Structured Interview Guide to assess the stakeholders' perceptions of intervention outcomes. Stakeholders will be asked open-ended questions about their knowledge of the interventions implemented during the study period, their perceptions of the outcomes of these interventions, and any perceived changes in ICU care delivery in time period that corresponds to the post-intervention phase of the study. The interview will last approximately 30 minutes and will be digitally recorded and transcribed. Specific topics of discussion include introduction, participant's definition/perception of their field, quality of care, team morale/staff satisfaction and final thoughts/comments.

A 15-20 minute self-administered online questionnaire will be used to obtain demographic information. It will include 9 questions, 6 of which are qualitative such as ICU role, part time or full time status, types of shifts worked, age group, gender identity (optional), and staff turnover.

The 3 quantitative questions are measured from 0-5, where 0 is strongly disagree/very dissatisfied and 5 is strongly agree/very satisfied.

Satisfaction relates to both job satisfaction and perceptions on whether staffing is efficient and promotes quality of care.

Perceptions on quality of care will be measured based on agreement with the statement "there are adequate support services to allow sufficient patient interactions".

Team morale has 3 sub questions: whether ICU physicians, nurses and allied health professional have good working relations, whether supervisory staff is supportive of ICU staff and whether there is sufficient teamwork between health care professionals.

The Education Evaluation Survey will be administered at the end of the workshop and emailed the day after to obtain post-intervention data. Participants will identify their job position and any prior knowledge relating to test/treatment/procedure misuse in Canadian hospitals. They will detail their comfort prior to the workshop in engaging in conversations with patients about reducing unnecessary standard tests/treatments.

Questions 4-8 can be answered by agree, neutral, disagree, don't know/non-applicable.

I enjoyed the workshop, topic and lecture. I enjoyed the discussion among my peers. I have an increased awareness of what standard tests, treatments and procedures may be unnecessary or even harmful to my patients. I feel more comfortable about sharing knowledge with my peers and patients about what standard tests, treatments and procedures may be unnecessary or even harmful to my patients. I am more likely to engage in reflexive practices related to my healthcare practice.

The short self-administered online questionnaire will evaluate ICU staff stress and burnout, as well as demographic variables discussed above. It will contain questions from the Perceived Stress Scale (PSS).

The PSS consists of 10 questions, answered on a scale of 0-4 depending on the frequency of which the behavior is observed, with 0 indicating "never" and 4 indicating "very often". Overall, a score of 0 indicates low stress, while a score of 40 indicates an individual with high perceived stress levels.

The short self-administered online questionnaire will evaluate ICU staff stress and burnout, as well as demographic variables discussed above. It will contain questions from the Maslach Burnout Inventory (MBI).

The MBI is a 22 question survey which evaluates 3 subscales; emotional exhaustion, depersonalization and reduced personal accomplishment. Each question is rated from 1 to 5, where 1 is strongly disagree and 5 is strongly agree. A high score on the emotional exhaustion subscale (27+) coupled with a high score on the depersonalization scale (10+) indicates that the individual may be experiencing 1+ symptoms of burnout.
