Status of robotic assisted surgery (RAS) and the effects of Coronavirus (COVID-19) on RAS in the Department of Defense (DoD)

Trends in industry payments and volume and distribution of robot-assisted surgeries

BACKGROUND

Considerable evidence links pharmaceutical industry payments to health providers' over-prescribing behavior. In response, public policies were enacted to mitigate this effect. However, there is limited evidence examining surgical device industry payments and surgeons' utilization of robot-assisted surgeries (RAS). This study assessed the relationship between industry payments to healthcare providers and the usage of RAS.

METHODS

Using 2015-2020 data from the CMS "Sunshine" Open Payments Database and New York State's (NYS) Statewide hospital discharge databases, we assessed temporal and spatial relationships between industry payments to hospitals and surgeons and volumes of RAS.

RESULTS

During 2015-2020, general surgery robotic device manufacturers paid providers more than $236 M nationwide. The highest proportion of payments was made toward "Education and training" (66.6%) and "Food and travel" (20.6%). In NYS, gastrointestinal (GI) RAS volume steadily increased by 182% (2015-2019, p < 0.01), while there was a 150% increase in general surgeon payments. Genitourinary (GU) and gynecological (GYN) surgeon payments remained unchanged but GU and GYN RAS volume increased by 17% and 75%, respectively, during this period (p < 0.05). Approximately, 93% of payments and 98% of abdomen and pelvic RAS in NYS were concentrated in metropolitan or non-rural counties.

CONCLUSIONS

With increasing payments from robotic device companies toward surgeon education and training, the use of RAS is likely to continue to rise in the long term. Unbiased and non-industry-funded studies examining RAS effect on surgeon behavior and patient outcomes are imperative to ensure system efficiency and patient safety.

The ethical landscape of robot-assisted surgery: a systematic review

Robot-assisted surgery has been widely adopted in recent years. However, compared to other health technologies operating in close proximity to patients in a vulnerable state, ethical issues of robot-assisted surgery have received less attention. Against the background of increasing automation that is expected to raise new ethical issues, this systematic review aims to map the state of the ethical debate in this field. A protocol was registered in the international prospective register of systematic reviews (PROSPERO CRD42023397951). Medline via PubMed, EMBASE, CINHAL, Philosophers' Index, IEEE Xplorer, Web of Science (Core Collection), Scopus and Google Scholar were searched in January 2023. Screening, extraction, and analysis were conducted independently by two authors. A qualitative narrative synthesis was performed. Out of 1723 records, 66 records were included in the final dataset. Seven major strands of the ethical debate emerged during the analysis. These include questions of harms and benefits, responsibility and control, professional-patient relationship, ethical issues in surgical training and learning, justice, translational questions, and economic considerations. The identified themes testify to a broad range of different ethical issues requiring careful deliberation and integration into the surgical ethos. Looking forward, we argue that a different perspective in addressing robotic surgical devices might be helpful to consider upcoming challenges of automation.

Understanding the challenges of robotic-assisted surgery adoption: Perspectives from stakeholders and the general population on human-interaction, built environment, and training

This study aims to explore adoption barriers from three aspects critical to facilitating robotic-assisted-surgery (RAS) adoption: the human-robot-interaction, built-environment, and training. Guidelines for research and design are identified from these perspectives. This study consisted of three phases: 1) surveys to RAS stakeholders and a crowd-sourcing survey; 2) stakeholder focus groups; and 3) a workshop with subject-matter experts to prioritize future research for RAS. Barriers from the human-robot-interaction perspective include hesitancy among clinicians to trust automation and physical discomfort during prolonged RAS. Barriers impeding communication and workflow disruptions were identified considering the built-environment. Training barriers were exemplified by varying curriculums from formal (courses) to informal (peer training) for surgeons. Crowd-sourced survey results suggest socio-economic status plays a role in RAS perception. Design guidelines include: 1) improved ergonomics; 2) deliberate introduction of automation; 3) sufficient in-room storage for prospective operating rooms; and 4) the development of compact RAS devices for older/smaller rooms.

Robotic technology in surgery; a classification system of soft tissue surgical robotic devices

BACKGROUND

The field of robotic-assisted surgery is rapidly growing as many robotic surgical devices are in development and about to enter the market. Currently, there is no universally accepted language for labeling the different robotic systems. To facilitate this communication, we created what is, to our knowledge, the first classification of surgical robotic technologies that organizes and classifies surgical robots used for endoscopy, laparoscopy and thoracoscopy.

METHODS

We compiled a list of surgical robots intended to be used for endoscopy, laparoscopy, and/or thoracoscopy by searching United States, European, Hong Kong, Japan, and Korean databases for approved devices. Devices showcased at the 2023 Annual Meeting for the Society of Robotic Surgery were added. We also systematically reviewed the literature for any existing surgical robotic classifications or categorizations. We then created a multidisciplinary committee of 8 surgeons and 2 engineers to construct a proposed classification of the devices included in our search.

RESULTS

We identified 40 robotic surgery systems intended to be used for endoscopy, laparoscopy and/or thoracoscopy. The proposed classification organizes robotic devices with regard to architecture, port design, and configuration (modular carts, multi-arm integrated cart, table-attachable or arm-table integration).

CONCLUSION

This 3-level classification of robotic surgical devices used for endoscopy, laparoscopy and/or thoracoscopy describes important characteristics of robotic devices systematically.

Need for formalized robotic training and curriculum in obstetrics and gynecology residency: an examination of current resident outlooks and perspectives

The objectives of this study were to evaluate current robotic surgery training methodologies for ACGME-accredited obstetrics and gynecology (OB/GYN) residency programs, better understand current resident perspectives, and explore potential areas for improvement within resident education. A cross-sectional study was done of ACGME-accredited OB/GYN residents in the 2023-2024 academic year. The study was done on a national setting via web-based survey. 75 surveys were included. The study was conducted via a 33-question survey study using a mixture of multiple choice, multiple answer, and Likert scale questions. Participants noted that 98.7% of their institutions perform robotic surgery and 90.7% have access to robotic console trainers. Outside of the operating room, slightly more than half of participants (57.3%) have formalized robotics training curriculums. A variety of training modalities were noted to be utilized by residents with the most helpful being hands-on training (67.7%) followed by dual-assist console (45.6%). The least helpful was noted to be online modules (58.7%). Most residents either strongly agree (45.3%) or agree (36.0%) that standardized robotics curriculums should be implemented for all OB/GYN residency programs. The largest barriers to completion of this training were noted to be attending comfort with resident participation in the case (74.0%), personal time (58.9%), and availability or access to trainers (42.5%). A formalized and standardized robotic training curriculum should be considered for OB/GYN residents with a multi-modal model utilizing a combination of training modalities as well as dedicated didactic hours.

Robotic Technology in Emergency General Surgery Cases in the Era of Minimally Invasive Surgery

Importance

Although robotic surgery has become an established approach for a wide range of elective operations, data on its utility and outcomes are limited in the setting of emergency general surgery.

Objectives

To describe temporal trends in the use of laparoscopic and robotic approaches and compare outcomes between robotic and laparoscopic surgery for 4 common emergent surgical procedures.

Design, Setting, and Participants

A retrospective cohort study of an all-payer discharge database of 829 US facilities was conducted from calendar years 2013 to 2021. Data analysis was performed from July 2022 to November 2023. A total of 1 067 263 emergent or urgent cholecystectomies (n = 793 800), colectomies (n = 89 098), inguinal hernia repairs (n = 65 039), and ventral hernia repairs (n = 119 326) in patients aged 18 years or older were included.

Exposure

Surgical approach (robotic, laparoscopic, or open) to emergent or urgent cholecystectomy, colectomy, inguinal hernia repair, or ventral hernia repair.

Main Outcomes and Measures

The primary outcome was the temporal trend in use of each operative approach (laparoscopic, robotic, or open). Secondary outcomes included conversion to open surgery and length of stay (both total and postoperative). Temporal trends were measured using linear regression. Propensity score matching was used to compare secondary outcomes between robotic and laparoscopic surgery groups.

Results

During the study period, the use of robotic surgery increased significantly year-over-year for all procedures: 0.7% for cholecystectomy, 0.9% for colectomy, 1.9% for inguinal hernia repair, and 1.1% for ventral hernia repair. There was a corresponding decrease in the open surgical approach for all cases. Compared with laparoscopy, robotic surgery was associated with a significantly lower risk of conversion to open surgery: cholecystectomy, 1.7% vs 3.0% (odds ratio [OR], 0.55 [95% CI, 0.49-0.62]); colectomy, 11.2% vs 25.5% (OR, 0.37 [95% CI, 0.32-0.42]); inguinal hernia repair, 2.4% vs 10.7% (OR, 0.21 [95% CI, 0.16-0.26]); and ventral hernia repair, 3.5% vs 10.9% (OR, 0.30 [95% CI, 0.25-0.36]). Robotic surgery was associated with shorter postoperative lengths of stay for colectomy (-0.48 [95% CI, -0.60 to -0.35] days), inguinal hernia repair (-0.20 [95% CI, -0.30 to -0.10] days), and ventral hernia repair (-0.16 [95% CI, -0.26 to -0.06] days).

Conclusions and Relevance

While robotic surgery is still not broadly used for emergency general surgery, the findings of this study suggest it is becoming more prevalent and may be associated with better outcomes as measured by reduced conversion to open surgery and decreased length of stay.

What do nurses experience in communication when assisting in robotic surgery: an integrative literature review

BACKGROUND

Communication in surgery is integral to the fundamentals of perioperative nursing practice and patient safety. Research exploring team communication in robotic-assisted surgery (RAS) is evident in the literature but little attention has been focused on how the experiences of operating room nurses' communication affect safety, practice and patient care outcomes.

OBJECTIVE

To synthesise current evidence regarding communication during robotic-assisted surgery as experienced by registered nurses.

DESIGN

An integrative literature review informed by Whittemore and Knafl's (2005) methodology was used to conduct a rigorous analysis and synthesis of evidence.

METHODS

A comprehensive database search was conducted using PRISMA guidelines. CINAHL, Pubmed, PsychINFO and British Nursing Web of Science databases were searched using a Boolean strategy.

RESULTS

Twenty-five relevant papers were included in this literature review. Thematic analysis revealed two main themes with four related subthemes. The two main themes are: 'Adaptive operating room nursing in RAS' and 'RAS alters team dynamics'. The four subthemes are: 'Navigating disruptions in RAS', 'RAS heightens interdependence on team working', 'Augmented communicative workflow in RAS', and 'Professional empowerment to speak up'.

CONCLUSIONS

This integrative review identifies how current research largely focuses on communication in the wider OR team. However, current evidence lacks the input of nurses. Therefore, further evidence is needed to explore nurses' experiences to highlight their perspectives.

CLINICAL RELEVANCE

Robotics significantly benefit patients, and this review identifies different challenges that robotic-assisted surgery nurses encounter. A better understanding of the communication from the perspective of nurses is needed to guide future research, practice education, policy development and leadership/management.

Characterization of the robotic surgery experience in minimally invasive surgery fellowships from 2010 to 2021

BACKGROUND

Robotic surgery has experienced exponential growth in the past decade. Few studies have evaluated the impact of robotics within minimally invasive surgery (MIS) fellowship training programs. The purpose of our study was to examine and characterize recent trends in robotic surgery within MIS fellowship training programs.

METHODS

De-identified case log data from the Fellowship Council from 2010 to 2021 were evaluated. Percentage of operations performed with robot assistance over time was assessed and compared to the laparoscopic and open experience. Case logs were further stratified by operative category (e.g., bariatric, hernia, foregut), and robotic experience over time was evaluated for each category. Programs were stratified by percent robot use and the experience over time within each quartile was evaluated.

RESULTS

MIS fellowship training programs with a robotic platform increased from 45.1% (51/113) to 90.4% (123/136) over the study period. The percentage of robotic cases increased from 2.0% (1127/56,033) to 23.2% (16,139/69,496) while laparoscopic cases decreased from 80.2% (44,954/56,033) to 65.3% (45,356/69,496). Hernia and colorectal case categories had the largest increase in robot usage [hernia: 0.7% (62/8614) to 38.4% (4661/12,135); colorectal 4.2% (116/2747) to 31.8% (666/2094)]. When stratified by percentage of robot utilization, current (2020-2021) programs in the > 95th percentile performed 21.8% (3523/16,139) of robotic operations and programs in the > 50th percentile performed 90.0% (14,533/16,139) of all robotic cases. The median number of robotic cases performed per MIS fellow significantly increased from 2010 to 2021 [0 (0-6) to 72.5 (17.8-171.5), p < 0.01].

CONCLUSIONS

Robotic use in MIS fellowship training programs has grown substantially in the past decade, but the laparoscopic and open experience remains robust. There remains an imbalance with the top 50% of busiest robotic programs performing over 90% of robot trainee cases. The experience in MIS programs varies widely and trainees should examine program case logs closely to confirm parallel interests.
