Innovative Approaches to Safe Surgery: A Narrative Synthesis of Best Practices

Augmented reality simulation framework for minimally invasive orthopedic surgery

PURPOSE

Minimally invasive surgery (MIS) has emerged in clinical practice to minimize surgical trauma, providing patients with faster recovery, reduced pain and complications and enhanced aesthetic results compared to traditional surgery. However, this approach increase the risk of iatrogenic damage, i.e. the accidental injury to sensitive anatomical structures (eg. nerves and vascular strcuteres) not directly visible during a percutaneous access. Augmented reality (AR) can effectively mitigate these drawbacks by overlaying graphical information onto the surgical field and providing real-time feedback, offering support in training settings and clinical practice. Implementation challenges have limited the number of case studies in the scientific literature. This study presents a novel simulation paradigm for orthopedic surgery training, filling a gap in surgical skill development resources for trainees, and demonstrating the effectiveness of this approach.

METHODS

The proposed methodology provides a framework for building a cost-effective and easily reproducible surgical training simulation environment. To address the challenge of mental spatial navigation during MIS procedures, the framework's rationale is to address the challenge of mental spatial navigation during MIS procedures. A surgical gesture tracking system using a commercial depth camera for comfortable simulation was developed. The principles of the acquisition system, image processing, and spatial computation mechanics are detailed to illustrate the framework's applicability. Digital environments customization with game engines to simulate expensive medical instrumentation, such as the C-arm, is also demonstrated. The simulation platform comprises a Computer Vision (CV) module, an X-ray machine simulation module, and an AR module.

RESULTS

System validation involved analysis at different framework levels. From texture analysis of acquired images to application accuracy evaluation, the influence of various parameters on system performance is demonstrated. The simulation system is a valuable tool for learning minimally invasive procedures and for developers building AR systems for medical applications. The implementation is focused on the insertion surgical devices, including screws and K-wires. This is results in real application in minimizing the risk of iatrogenic injury to neural and vascular structures. To demonstrate the effectiveness of highly reproducible accuracy between real and virtual environment an analysis of errors and accuracies is illustrated at level of different subsystems. Measurement between comparative measurement between vernier caliper and simulation system methods shows a R>0.9 with a p<0.01. Application accuracy was evaluated using the following parameters. The relative point-to-point accuracy averaged 1.02mm with a standard deviation of 2.82mm. Future development includes clinical implementation and integration of advanced AI technologies.

Multicenter audit of operating room staff compliance with the surgical safety checklist: a cross-sectional study from a low- and middle-income country

BACKGROUND

Unsafe surgical practices are a preventable cause of morbidity and mortality. The WHO published its surgical safety checklist (SSC) to help reduce surgical errors and complications and improve patient outcomes. This study aims to audit compliance with the WHO's SSC and explore attitudes toward its implementation in hospitals within a low- and middle-income country.

METHODS

This was a two-part, cross-sectional study in which a retrospective desk review was used to audit compliance with SSC use, and a questionnaire was used to explore attitudes toward the SSC. The data were collected between September and November 2021 from two major governmental and nongovernmental hospitals. Surgeons, anesthesiologists, and surgical nurses were invited to complete a self-administered questionnaire that measured attitudes across five domains via a 5-point Likert scale.

RESULTS

The final sample consisted of 340 patients whose records were retrieved from one governmental hospital (n=170) and one nongovernmental hospital (n=170). Among those patients, 93 (27.4%) underwent general surgery, 49 (14.4%) underwent orthopedic surgery, and 45 (13.2%) underwent pediatric surgery. The SSCs were fully completed for 27.9% of the patients, partially completed for 43.2% of the patients, and left blank for 28.8% of the patients. Compliance with the use of the SSC was significantly associated with age (p=0.002), sex (p=0.022), type of surgery (p<0.001), classification of surgery (p=0.006) and hospital sector (p<0.001). None of the patients at the governmental hospital had a completely filled the SSC, whereas none of those at the nongovernmental hospital had a blank SSC. Among the final sample of 80 operating room staff members included in the study that explored their attitudes, 41.3%, 40.0%, and 18.8% were surgeons, surgical nurses, and anesthesiologists, respectively. The participants demonstrated positive attitudes toward the SSC across all the attitude domains. The majority said that lack of time (56.3%), staff assertiveness (55.0%), and training (53.8%) were the most important barriers to implementing the SSC. The hospital sector was significantly associated with higher scores across all domains.

CONCLUSIONS

While the majority of operating room staff used the SSC, only a minority filled the list completely. The attitudes toward using the WHO's SSC trended positively, which encourages the official implementation of the SSC at the national level. Addressing the identified barriers may enhance the quality of implementation by providing educational sessions. Future reaudits are recommended to enhance the adaptability of the SSC.

Exploring strategies to enhance patient safety in spine surgery: a review

Patient safety is the foundation of spine surgery, where the intricate nature of spinal procedures and the unique risks involved call for exceptional diligence and comprehensive protocols. In this high-stakes field, developing and implementing rigorous safety protocols is not only vital for minimizing complications but also for achieving the best possible outcomes and strengthening the confidence patients have in their care team. Each patient entrusts their well-being to their surgical team. This trust underscores the responsibility healthcare providers have to prioritize safety at every stage. In spine surgery, thorough preoperative planning, clear communication during informed consent, and vigilant postoperative care are all crucial for creating a safe environment tailored to each patient's needs. A commitment to patient safety requires more than individual efforts; it calls for a coordinated, multidisciplinary approach where surgeons, nurses, anesthesiologists, and rehabilitation specialists work closely together. This collaboration ensures that each step of the patient's journey is aligned with best practices for safety and care. This review highlights the critical need for ongoing evaluation and refinement of safety protocols in spine surgery. As surgical techniques and technologies advance, and as patients' needs evolve, healthcare teams must remain responsive, cultivating a culture of safety that is both proactive and adaptable. Continuous investment in quality improvement and research is essential to fine-tune these protocols, ensuring they remain both relevant and effective in addressing the unique challenges of spine surgery. Prioritizing comprehensive safety measures goes beyond improving surgical outcomes; it plays a pivotal role in strengthening the trust and confidence patients have in their healthcare providers. By committing to these robust protocols, we reaffirm our dedication to patient-centered care, enhancing not only patient safety and recovery but also fostering a deeper faith in a healthcare system that places patient well-being at the forefront.

Acceptance and use of extended reality in surgical training: an umbrella review

BACKGROUND

Extended reality (XR) technologies which include virtual, augmented, and mixed reality have significant potential in surgical training, because they can help to eliminate the limitations of traditional methods. This umbrella review aimed to investigate factors that influence the acceptance and use of XR in surgical training using the unified theory of acceptance and use of technology (UTAUT) model.

METHODS

An umbrella review was conducted in 2024 by searching various databases until the end of 2023. Studies were selected based on the predefined eligibility criteria and analyzed using the components of the UTAUT model. The quality and risk of bias of the selected studies were assessed, and the findings were reported descriptively.

RESULTS

A total of 44 articles were included in this study. In most studies, XR technologies were used for surgical training of orthopedics, neurology, and laparoscopy. Based on the UTAUT model, the findings indicated that XR technologies improved surgical skills and procedural accuracy while simultaneously reducing risks and operating room time (performance expectancy). In terms of effort expectancy, user-friendly systems were accessible for the trainees with various levels of expertise. From a social influence standpoint, XR technologies enhanced learning by providing positive feedback from experienced surgeons during surgical training. In addition, facilitating conditions emphasized the importance of resource availability and addressing technical and financial limitations to maximize the effectiveness of XR technologies in surgical training.

CONCLUSIONS

XR technologies significantly improve surgical training by increasing skills and procedural accuracy. Although adoption is facilitated by designing user-friendly interfaces and positive social influences, financial and resource challenges must be overcome, too. The successful integration of XR into surgical training necessitates careful curriculum design and resource allocation. Future research should focus on overcoming these barriers, so that XR can fully realize its potential in surgical training.

Technological Advancements in Augmented, Mixed, and Virtual Reality Technologies for Surgery: A Systematic Review

Recent advancements in artificial intelligence (AI) have shown significant potential in the medical field, although many applications are still in the research phase. This paper provides a comprehensive review of advancements in augmented reality (AR), mixed reality (MR), and virtual reality (VR) for surgical applications from 2019 to 2024 to accelerate the transition of AI from the research to the clinical phase. This paper also provides an overview of proposed databases for further use in extended reality (XR), which includes AR, MR, and VR, as well as a summary of typical research applications involving XR in surgical practices. Additionally, this paper concludes by discussing challenges and proposed solutions for the application of XR in the medical field. Although the areas of focus and specific implementations vary among AR, MR, and VR, current trends in XR focus mainly on reducing workload and minimizing surgical errors through navigation, training, and machine learning-based visualization. Through analyzing these trends, AR and MR have greater advantages for intraoperative surgical functions, whereas VR is limited to preoperative training and surgical preparation. VR faces additional limitations, and its use has been reduced in research since the first applications of XR, which likely suggests the same will happen with further development. Nonetheless, with increased access to technology and the ability to overcome the black box problem, XR's applications in medical fields and surgery will increase to guarantee further accuracy and precision while reducing risk and workload.

The effect of family-centered care on unplanned emergency room visits, hospital readmissions and intensive care admissions after surgery: a root cause analysis from a prospective multicenter study in the Netherlands

BACKGROUND

Optimizing transitional care by practicing family-centered care might reduce unplanned events for patients who undergo major abdominal cancer surgery. However, it remains unknown whether involving family caregivers in patients' healthcare also has negative consequences for patient safety. This study assessed the safety of family involvement in patients' healthcare by examining the cause of unplanned events in patients who participated in a family involvement program (FIP) after major abdominal cancer surgery.

METHODS

This is a secondary analysis focusing on the intervention group of a prospective cohort study conducted in the Netherlands. Data were collected from April 2019 to May 2022. Participants in the intervention group were patients who engaged in a FIP. Unplanned events were analyzed, and root causes were identified using the medical version of a prevention- and recovery-information system for monitoring and analysis (PRISMA) that analyses unintended events in healthcare. Unplanned events were compared between patients who received care from family caregivers and patients who received professional at-home care after discharge. A Mann-Whitney U test was used to analyze data.

RESULTS

Of the 152 FIP participants, 68 experienced an unplanned event and were included. 112 unplanned events occurred with 145 root causes since some unplanned events had several root causes. Most root causes of unplanned events were patient-related factors (n = 109, 75%), such as patient characteristics and disease-related factors. No root causes due to inadequate healthcare from the family caregiver were identified. Unplanned events did not differ statistically (interquartile range 1-2) (p = 0.35) between patients who received care from trained family caregivers and those who received professional at-home care after discharge.

CONCLUSION

Based on the insights from the root-cause analysis in this prospective multicenter study, it appears that unplanned emergency room visits and hospital readmissions are not related to the active involvement of family caregivers in surgical follow-up care. Moreover, surgical follow-up care by trained family caregivers during hospitalization was not associated with increased rates of unplanned adverse events. Hence, the concept of active family involvement by proficiently trained family caregivers in postoperative care appears safe and feasible for patients undergoing major abdominal surgery.
