Design outcomes

Primary

MeasureTime frame
1.Change in knowledge regarding ecological sustainability in perioperative medicine WHEN: before the intervention (T0) and after the intervention (T1, approx. 6 months after implementation of the educational program) HOW: using a study-specific online questionnaire “THE GREEN THEATRE” (partly based on validated instruments), analyzed via a score (maximum 24 points) 2.Change in attitudes toward environmentally sustainable practice WHEN: T0 (pre-intervention) and T1 (post-intervention, approx. 6 months) HOW: using the study-specific online questionnaire “THE GREEN THEATRE” (Likert-scale-based items) 3.Change in fresh gas flow (as a surrogate parameter for anesthetic gas emissions) WHEN: T0: before the intervention (data collection over approx. 3 weeks) T1: after the intervention (data collection over approx. 3 weeks after completion of the first training cycle) HOW: direct measurement at anesthesia machines by study personnel (documentation of fresh gas flow in L/min) 4.Change in the amount of correctly separated recyclable waste WHEN: T0: before the intervention (data collection over 2 weeks) T1: after the intervention (data collection over 2 weeks) HOW: counting of waste bags classified as correctly sorted recyclable waste at the central waste disposal site.

Secondary

MeasureTime frame
1.Transfer of knowledge into sustainable practice (self-reported) WHEN: T1 (post-intervention, approx. 6 months) HOW: using the online questionnaire “THE GREEN THEATRE” 2.Identification of barriers to sustainable behavior in clinical practice WHEN: T0 and T1 HOW: using the online questionnaire “THE GREEN THEATRE” (free-text and multiple-choice items) 3.Change in anesthetic consumption WHEN: before and after the intervention (corresponding to T0 and T1) HOW: analysis of internal hospital procurement and consumption data (aggregated data)
