[Process optimization in the operating room area]

The operating room (OR) accounts for the highest fraction of hospital costs and also has the largest proportion of revenue. Classical goals of optimizing OR efficiency are to increase the quality of treatment and economic success. As the reduction of qualified personnel as the largest cost factor was favored for many years, nowadays a shortage of nursing personnel is threatening the surgery departments in many German hospitals.

Which improvements are possible while the OR already suffers from restrictions? What are critical resources, what are the critical burdens and how can they be optimized?

An analysis of the OR organization of an orthopedic and traumatology department with reduced OR capacity due to a shortage of OR and anesthesia nursing personnel was performed. This was followed by the evaluation of possible alterations with the corresponding advantages and disadvantages. After selection and implementation, the qualitative and quantitative differences were examined before and after the alterations.

Multifaceted problem areas could be identified. The establishment of a fast track OR with concentration of additional resources on many fast points in an OR instead of on a few complex cases was selected and implemented. The installation of a holding area for patients waiting for surgery eliminated transportation delays almost entirely. Alterations in the OR planning and capacity distribution reduced nocturnal operating times. Despite reduction of the OR capacity both the number of operations performed and the incision to suture times could be increased.

Optimization of the processes in the OR is possible and necessary, despite the lack of personnel. Even only a few structural changes can eliminate bottlenecks, resulting in qualitative and quantitative improvements.
