Impact of operating room technology on intra-operative nurses' workload and job satisfaction
An observational study
Background: The integration of medical technology in the operating room has revolutionized surgical workflows and team dynamics. However, this progress coincides with a critical global shortage of nurses and a high turnover rate within the existing nursing workforce, impacting patient care quality, nurses' well-being, and hospital finances Aim: This study investigates the impact of technological complexity on the workload and job satisfaction of intra-operative nurses, focusing on open surgery, minimally invasive surgery, and robotic-assisted surgery within the gynecology department of a Dutch academic hospital. Method: The study design follows a mixed-methods approach, combining qualitative and quantitative methods to assess nursing experiences across three surgical modalities. Specifically, we conducted 5 interviews, distributed 28 validated questionnaires, performed automated video analysis on 35 recorded surgeries, and analyzed hospital datasets encompassing 411 cases. Data collection took place in 2022 and 2023. Results: Findings show that intra-operative nurses experience varying levels of workload and job satisfaction depending on the level of technology. Open procedures showed the highest job satisfaction, characterized by continuous engagement and manageable workloads. Minimally invasive surgery procedures, while less physically demanding, were associated with reduced involvement and lower satisfaction. Robotic-assisted procedures presented the most significant challenges, with increased workload, reduced involvement, and heightened stress stemming from surgery preparation, technological complexity, and altered team dynamics. Conclusions: Advancements in medical technology improve outcomes and efficiency but often neglect their impact on intra-operative nurses. Communication issues, equipment challenges, and limited technical training contribute to burnout and turnover. This study underscores the need for supportive operating room environments that prioritize nurses’ well-being. By examining the link between technology, workload, and satisfaction, it offers strategies to retain and empower nursing staff. It also shows how automated video analysis can objectively assess nursing roles, highlighting the importance of balancing technology with human-centered care in the operating room.
Perioperative staff shortages are a problem in hospitals worldwide. Keeping the staff content and motivated is a challenge in the busy hospital setting of today. New operating room technologies aim to increase safety and efficiency. This causes a shift from interaction with patients to interaction with technology. Objectively measuring this shift could aid the design of supportive technological products, or optimal planning for high-tech procedures.
Methods
35 Gynaecological procedures of three different technology levels are recorded: open- (OS), minimally invasive- (MIS) and robot-assisted (RAS) surgery. We annotate interaction between staff and the patient. An algorithm is proposed that detects interaction with the operating table from staff posture and movement. Interaction is expressed as a percentage of total working time.
Results
The proposed algorithm measures operating table interactions of 70.4%, 70.3% and 30.1% during OS, MIS and RAS. Annotations yield patient interaction percentages of 37.6%, 38.3% and 24.6%. Algorithm measurements over time show operating table and patient interaction peaks at anomalous events or workflow phase transitions.
Conclusions
The annotations show less operating table and patient interactions during RAS than OS and MIS. Annotated patient interaction and measured operating table interaction show similar differences between procedures and workflow phases. The visual complexity of operating rooms complicates pose tracking, deteriorating the algorithm input quality. The proposed algorithm shows promise as a component in context-aware event- or workflow phase detection. ...

Contextual Operating Room Monitoring
What pixels tell us about workflow
Efforts are made to improve this situation by assisting hospital employees in their work. New tools can ease tasks, and make them more efficient or safer. Alternatively, finding and teaching optimal ways of working improves workflow efficiency. The desired outcome is to compensate personnel shortages by decreasing the load on employees, whilst maintaining availability and quality of care.
Supportive healthcare tools are often implemented using technology. For example, artificial intelligence (AI) helps find disease in medical imaging, and may assist procedure planning. Devices enable e.g. clear X-Ray imaging with minimal radiation, and steady robotic surgery. However, technological changes to the perioperative setting can burden healthcare professionals in some situations. Beside the patient, they now need to pay attention to these devices. Malfunctions can delay procedures, cause risks for the patient, and induce stress in the staff.
Education through workflow analysisand optimisation presents an unintrusive path to efficiency improvements. Where process optimisation is already mature in industry, these techniques do not translate directly to hospitals. Healthcare tasks cannot be divided and simplified as in some industries, and every patient has unique needs. However, knowledge-based feedback and support can still be beneficial. Analysing on scale how specialists work allows to extract best practices for safety, efficiency and wellbeing. For example, workflow insights can reveal optimal procedure scheduling, approaches to a workflow phase, adaptation to different patients, and use of new technologies. A current challenge therefore is to formulate scalable workflow analysis methods in hospitals.
Automation through algorithms is a promising tool for scalable workflow analysis, where recorded data from the OR can be translated to workflow metrics. Available datastreams include (monitoring) videos, device logs, and diagnostic measurements. Differences in protocol and workflow preference between hospitals and medical teams present difficulties. Perioperative workflow analysis must be robust against such variability, recognising relevant patterns regardless of the team or OR. One technology that excels at such robust pattern recognition is deep learning.
Datastreams from the OR present a tradeoff between scope and generalisability. For example, devices may keep logs, which generalise well between ORs, but have a small scope as only device usage is recorded. Although monitoring videos generalise poorly due to visually unique ORs and viewpoints, their view of the whole room yields a large scope. This dissertation investigates the use of monitoring videos for generalisable workflow analysis. Cameras were mounted on the ceiling in a cardiac catheterisation laboratory (Cath Lab) and several ORs. The Cath Lab is a special OR for minimally invasive cardiac interventions, which high level of standardisation presents opportunities for explorative workflow study. Videos of several hundreds of real interventional procedures were recorded. Computer vision (CV) algorithms were used to extract visualand workflow features. ...

This study evaluates the performance of deep learning models in the prediction of the end time of procedures performed in the cardiac catheterization laboratory (cath lab). We employed only the clinical phases derived from video analysis as input to the algorithms. Our results show that InceptionTime and LSTM-FCN yielded the most accurate predictions. InceptionTime achieves Mean Absolute Error (MAE) values below 5 min and Symmetric Mean Absolute Percentage Error (SMAPE) under 6% at 60-s sampling intervals. In contrast, LSTM with attention mechanism and standard LSTM models have higher error rates, indicating challenges in handling both long-term and short-term dependencies. CNN-based models, especially InceptionTime, excel at feature extraction across different scales, making them effective for time-series predictions. We also analyzed training and testing times. CNN models, despite higher computational costs, significantly reduce prediction errors. The Transformer model has the fastest inference time, making it ideal for real-time applications. An ensemble model derived by averaging the two best performing algorithms reported low MAE and SMAPE, although needing longer training. Future research should validate these findings across different procedural contexts and explore ways to optimize training times without losing accuracy. Integrating these models into clinical scheduling systems could improve efficiency in cath labs. Our research demonstrates that the models we implemented can form the basis of an automated tool, which predicts the optimal time to call the next patient with an average error of approximately 30 s. These findings show the effectiveness of deep learning models, especially CNN-based architectures, in accurately predicting procedure end times.
Deep learning-based object detectors, while offering exceptional performance, are data-dependent and can suffer from generalization issues. In this work, we investigated deep neural networks for detecting people and medical instruments for the vision-based workflow analysis system inside Catheterization Laboratories (Cath Labs). The central problem explored in this paper is the fact that the performance of the detector can degrade drastically if it is trained and tested on data from different Cath Labs. Our research aimed to investigate the underlying causes of this specific performance degradation and find solutions to mitigate this issue. We employed the YOLOv8 object detector and created datasets from clinical procedures recorded at Reinier de Graaf Hospital (RdGG) and Philips Best Campus, supplemented with publicly accessible images. Through a series of experiments complemented by data visualization, we discovered that the performance degradation primarily stems from data distribution shifts in the feature space. Notably, the object detector trained on non-sensitive online images can generalize to unseen Cath Labs, outperforming the model trained on a procedure recording from a different Cath Lab. The detector trained on the online images achieved an mAP@0.5 of 0.517 on the RdGG dataset. Furthermore, by switching to the most suitable camera for each object in the Cath Lab, the multi-camera system can further improve the detection performance significantly. An aggregated L-camera mAP@0.5 of 0.679 is achieved for single-object classes on the RdGG dataset.
