German hospitals are increasingly being asked to improve efficiency while striving to enhancethe quality of standards that will afford a high level of patient safety and quality in thetreatment process. The main objective of this Ph.D. thesis was to analyze whether digitalsupport software used during surgery has a positive effect on selected clinical process andquality ratios in orthopedics. Two retrospective case-control studies of 383 hip jointendoprosthetic implantations and 297 knee joint endoprosthetic implantations wereconducted at a German hospital between 2015 and 2020. Statistically significant results wereevaluated commercially within the framework of the German diagnosis-related groups.Results show that the use of digitally assisted surgery leads to significantly shorter hospitalstays and reduces postoperative complications, which in turn has a direct impact on treatmentcosts and hospital revenues.
