The Application of Human Factors Engineering to Reduce Operating Room Turnover in Robotic Surgery.

BACKGROUND: Challenges associated with turnover time are magnified in robotic surgery. The introduction of advanced technology increases the complexity of an already intricate perioperative environment. We applied a human factors approach to develop systematic, data-driven interventions to reduce robotic surgery turnover time. METHODS: Researchers observed 40 robotic surgery turnovers at a tertiary hospital [20 pre-intervention (Jan 2018 to Apr 2018), 20 post-intervention (Jan 2019 to Jun 2019)]. Components of turnover time, including cleaning, instrument and room set-up, robot preparation, flow disruptions, and major delays, were documented and analyzed. Surveys and focus groups were used to investigate staff perceptions of robotic surgery turnover time. A multidisciplinary team of human factors experts and physicians developed targeted interventions. Pre- and post-intervention turnovers were compared. RESULTS: Median turnover time was 67 min (mean: 72, SD: 24) and 22 major delays were noted (1.1/case). The largest contributors were instrument setup (25.5 min) and cleaning (25 min). Interventions included an electronic dashboard for turnover time reporting, clear designation of roles and simultaneous completion of tasks, process standardization of operating room cleaning, and data transparency through monthly reporting. Post-intervention turnovers were significantly shorter (U = 57.5, p = .000) and ten major delays were noted. CONCLUSIONS: Human factors analysis generated interventions to improve turnover time. Significant improvements were seen post-intervention with a reduction in turnover time by a 26 min and decrease in major delays by over 50%. Future opportunities to intervene and further improve turnover time include targeting pre- and post-operative care phases.

Discovering the barriers to efficient robotic operating room turnover time: perceptions vs. reality.

Turnover time (TOT) has remained the subject of numerous research articles and operating room (OR) committee discussions. Inefficiencies associated with TOT are multiplied when complex technology, such as surgical robots, is involved. Using a human factors approach, this study investigated impediments to efficient robotic TOT and team members' perceptions surrounding this topic. Researchers observed 20 robotic turnovers over 2 months at a tertiary hospital. TOT, cleaning time, number of staff present, bed set-up time, instrument set-up time and any major delays were recorded. Additionally, 79 OR team members completed a questionnaire regarding perceptions of OR turnover. Average TOT was 72 min (s, 24 min). Overall, cleaning required the most time (average of 27.4 min, 37.96% of TOT), followed by instrument set-up (15.4 min, 21.34% of TOT) and RN retrieval of the patient from pre-op (12 min, 17.72% of TOT). OR team members estimated that turnovers require 60.36 min. Physicians believed the greatest contributor to TOT was "time to set up the OR", while OR staff rated "instrument availability" as the greatest issue, both of which were inaccurate. OR team members' perceptions of robotic TOT and contributing factors were different from reality based on observed contributors. Data demonstrated several areas of opportunity for process improvement. These data can be used to guide the implementation of targeted interventions to improve TOT efficiency.

Median Arcuate Ligament Syndrome and Its Associated Conditions.

The risk factors and associated conditions of median arcuate ligament syndrome (MALS) have not been well characterized in the literature. In this study, we aim to investigate the presentation and outcomes of MALS patients with an emphasis on the prevalence of other uncommon disorders. To this end, data of patients with MALS who underwent surgery between 2013 and 2018 were collected and compiled into a retrospective database and analyzed. Eleven patients were identified. Seven of these eleven patients underwent diagnostics to evaluate gastric emptying. Five of these seven patients (71.4%) had radiographic evidence of delayed gastric emptying. Four of the eleven patients (36.4%) were found to have anatomic abnormalities of their visceral vasculature. Two of the eleven patients (18.2%) were found to have connective tissue disorders, both with Ehlers-Danlos syndrome. Three of the eleven (27.3%) had a diagnosis of postural orthostatic tachycardia syndrome. This is the first case series reporting on an association between MALS and delayed gastric emptying. We also explored the relationship between MALS and visceral vascular abnormalities, Ehlers-Danlos syndrome, and postural orthostatic tachycardia syndrome. It is notable that these conditions are more prevalent in the MALS population than in the general population, suggesting a possible pathophysiologic relationship.
