Show moreThe main objectives of this thesis are to obtain clinically relevant tools to evaluate quality during the introduction of new interventions in laparoscopic hysterectomy (LH) (the most frequently performed advanced gynecological minimally invasive procedure) and to support clinicians to ensure surgical safety by means of process analysis. We performed a Delphi study to achieve consensus on a uniform and multidisciplinary applicable definition. Based on this definition, we described the relevance, evidence and controllability of conversion rate as a means of evaluation in LH. We performed a systematic review with cumulative analysis to evaluate the outcomes of abdominal, laparoscopic and vaginal hysterectomy (VH) in patients with a BMI ≥35kg/m2 and concluded that the feasibility of LH and VH should be considered prior to the abdominal approach to hysterectomy in these patients. Furthermore, we performed a prospective study using video observation, to assess the incidence and effect of equipment-/instrument-related surgical flow disturbances during LH and validated a questionnaire to detect potential safety hazards during the introduction of new interventions in an early stage. Finally, the Digital Operating Room Assistance (DORA) model was introduced which is a novel system for automated procedural progress monitoring that enables prediction of the remaining procedure duration.
