Identification of surgeon-individual treatment profiles to support the provision of an optimum treatment service for cataract patients.

One objective of ophthalmological departments is the optimization of patient treatment services. A strategy for optimization is the identification of individual potential for advanced training of surgeons based on their daily working results. The objective of this feasibility study was the presentation and evaluation of a strategy for the computation of surgeon-individual treatment profiles (SiTPs). We observed experienced surgeons during their standard daily performance of cataract procedures in the Ophthalmological Department of the University Medical Center Leipzig, Germany. One hundred five cases of cataract procedures were measured as Surgical Process Models (SPMs) with a detailed-to-the-second resolution. The procedures were performed by three different surgeons during their daily work. Subsequently, SiTPs were computed and analyzed from the SPMs as statistical 'mean' treatment strategies for each of the surgeons. The feasibility study demonstrated that it is possible to identify differences in surgeon-individual treatment profiles beyond the resolution of cut-suture times. Surgeon-individual workflows, activity frequencies and average performance durations of surgical activities during cataract procedures were analyzed. Highly significant (p < 0.001) workflow differences were found between the treatment profiles of the three surgeons. Conclusively, the generation of SiTPs is a convenient strategy to identify surgeon-individual training potentials in cataract surgery. Concrete recommendations for further education can be derived from the profiles.
