Background Studies have thus far neglected to evaluate the impact of the da Vinci single port (SP) robotic platform on surgeon experience and operating room efficiency. We sought to assess the effect of the SP platform on surgeon cognitive load measures during robotic assisted laparoscopic prostatectomy (RALP). Methods We prospectively compared the first 20 SP‐RALPs performed at our institution to 20 multi‐port (MP)‐RALPs performed by a single experienced robotic surgeon. Three multi‐dimensional assessment tools were used to evaluate mental and surgical workload, teamwork and workflow disruptions. Results No statistically significant differences were found between the MP‐RALP and SP‐RALP cohorts when evaluated by NASA Task Load Index, Surgery Task Load Index and Observational Teamwork Assessments. Conclusions The SP robotic platform did not adversely affect human factor performance of the surgeon during RALP. Multi‐institutional validation will be necessary to confirm these initial findings.

Effectiveness of computer vision techniques has been demonstrated through a number of applications, both within and outside healthcare. The operating room environment specifically is a setting with rich data sources compatible with computational approaches and high potential for direct patient benefit. The aim of this review is to summarize major topics in computer vision for surgical domains. The major capabilities of computer vision are described as an aid to surgical teams to improve performance and contribute to enhanced patient safety. Literature was identified through leading experts in the fields of surgery, computational analysis and modeling in medicine,

“…Similarly, Shiferaw et al [5] for example found an increase in GTE in sleep deprived drivers. Moreover, increases in stationary entropy were found in surgeons under higher task load [20,65]. These results indicate that the regularity of scanning behavior can decline under conditions in which observers feel under pressure or are suffering from context-driven cognitive impairments, thus resulting in higher entropy values.…”

Scan pattern analysis has been discussed as a promising tool in the context of real-time gaze-based applications. In particular, information-theoretic measures of scan path predictability, such as the gaze transition entropy (GTE), have been proposed for detecting relevant changes in user state or task demand. These measures model scan patterns as first-order Markov chains, assuming that only the location of the previous fixation is predictive of the next fixation in time. However, this assumption may not be sufficient in general, as recent research has shown that scan patterns may also exhibit more long-range temporal correlations. Thus, we here evaluate the active information storage (AIS) as a novel information-theoretic approach to quantifying scan path predictability in a dynamic task. In contrast to the GTE, the AIS provides means to statistically test and account for temporal correlations in scan path data beyond the previous last fixation. We compare AIS to GTE in a driving simulator experiment, in which participants drove in a highway scenario, where trials were defined based on an experimental manipulation that encouraged the driver to start an overtaking maneuver. Two levels of difficulty were realized by varying the time left to complete the task. We found that individual observers indeed showed temporal correlations beyond a single past fixation and that the length of the correlation varied between observers. No effect of task difficulty was observed on scan path predictability for either AIS or GTE, but we found a significant increase in predictability during overtaking. Importantly, for participants for which the first-order Markov chain assumption did not hold, this was only shown using AIS but not GTE. We conclude that accounting for longer time horizons in scan paths in a personalized fashion is beneficial for interpreting gaze pattern in dynamic tasks.
