Short-term quality of life after myomectomy for uterine fibroids from the COMPARE-UF Fibroid Registry.

BACKGROUND: Uterine fibroids may decrease quality of life in a significant proportion of affected women. Myomectomy offers a uterine-sparing treatment option for patients with uterine fibroids that can be performed abdominally, laparoscopically (with or without robotic assistance), and hysteroscopically. Quality of life information using validated measures for different myomectomy routes, especially hysteroscopic myomectomy, is limited. OBJECTIVE: To compare women's perception of their short-term health-related quality of life measures and reported time to return to usual activities and return to work for different routes of myomectomy. MATERIALS AND METHODS: Comparing Options for Management: Patient-centered Results for Uterine Fibroids (COMPARE-UF) is a prospective nationwide fibroid registry that enrolled premenopausal women seeking treatment for uterine fibroids at 8 clinical sites. For this analysis, we included women undergoing hysteroscopic, abdominal, or laparoscopic myomectomy who completed the postprocedure questionnaire scheduled between 6 and 12 weeks after surgery. Health-related quality of life outcomes, such as pain, anxiety, and return to usual activitie, were assessed for each route. The hysteroscopic myomectomy group had large differences in demographics, fibroid number, and uterine size compared to the other groups; thus, a direct comparison of quality of life measures was performed only for abdominal and laparoscopic approaches after propensity weighting. Propensity weighting was done using 24 variables that included demographics, quality of life baseline measures, and fibroid and uterine measurements. RESULTS: A total of 1206 women from 8 COMPARE-UF sites underwent myomectomy (338 hysteroscopic, 519 laparoscopic, and 349 abdominal). All women had substantial improvement in short-term health-related quality of life and symptom severity scores, which was not different among groups. Average symptom severity scores decreased about 30 points in each group. Return to usual activities averaged 0 days (interquartile range, 0-14 days) for hysteroscopic myomectomy, 21 days (interquartile range, 14-28 days) for laparoscopic myomectomy, and 28 days (interquartile range, 14-35 days) for abdominal myomectomy. After propensity adjustment, quality of life outcomes in the laparoscopic and abdominal myomectomy groups were similar except for more anxiety in the laparoscopic myomectomy group and slightly more pain in the abdominal myomectomy group. After propensity weighting, return to usual activities favored laparoscopic compared to abdominal procedures; median time was the same at 21 days, but the highest quartile of women in the abdominal group needed an additional week of recovery (interquartile range,14.0-28.0 for laparoscopic versus 14.0-35.0 for abdominal, P < .01). Time to return to work was also longer in the abdominal arm (median, 22 days; interquartile range, 14-40 days, versus median, 42; interquartile range, 27-56). CONCLUSION: Women who underwent myomectomy had substantial improvement in health-related quality of life, regardless of route of myomectomy. After propensity weighting, abdominal myomectomy was associated with a nearly 2-week longer time to return to work than laparoscopic myomectomy.

General surgery training in the era of robotic surgery: a qualitative analysis of perceptions from resident and attending surgeons.

BACKGROUND: The use of the surgical robot has increased annually since its introduction, especially in general surgery. Despite the tremendous increase in utilization, there are currently no validated curricula to train residents in robotic surgery, and the effects of robotic surgery on general surgery residency training are not well defined. In this study, we aim to explore the perceptions of resident and attending surgeons toward robotic surgery education in general surgery residency training. METHODS: We performed a qualitative thematic analysis of in-person, one-on-one, semi-structured interviews with general surgery residents and attending surgeons at a large academic health system. Convenient and purposeful sampling was performed in order to ensure diverse demographics, experiences, and opinions were represented. Data were analyzed continuously, and interviews were conducted until thematic saturation was reached, which occurred after 20 residents and seven attendings. RESULTS: All interviewees agreed that dual consoles are necessary to maximize the teaching potential of the robotic platform, and the importance of simulation and simulators in robotic surgery education is paramount. However, further work to ensure proper access to simulation resources for residents is necessary. While most recognize that bedside-assist skills are essential, most think its educational value plateaus quickly. Lastly, residents believe that earlier exposure to robotic surgery is necessary and that almost every case has a portion that is level-appropriate for residents to perform on the robot. CONCLUSIONS: As robotic surgery transitions from novelty to ubiquity, the importance of effective general surgery robotic surgery training during residency is paramount. Through in-depth interviews, this study provides examples of effective educational tools and techniques, highlights the importance of simulation, and explores opinions regarding the role of the resident in robotic surgery education. We hope the insights gained from this study can be used to develop and/or refine robotic surgery curricula.

Impact of robotic assistance on mental workload and cognitive performance of surgical trainees performing a complex minimally invasive suturing task.

BACKGROUND: Few studies have investigated the potential impact of robotic assistance on cognitive ergonomics during advanced minimally invasive surgery. The purpose of this study was to assess the impact of robotic assistance on mental workload and downstream cognitive performance in surgical trainees. METHODS: Robot-naïve trainees from general surgery, urology and gynaecology, stratified by specialty and level of training, were randomised to either laparoscopic surgery (LS) or robotic-assisted laparoscopic surgery (RALS) and performed a time-limited, complex laparoscopic suturing task after watching a 5-min instructional video. The RALS group received an additional 5-min orientation to the robotic console. Subjective mental workload was measured using NASA Task Load Index. Concentration and executive cognitive function were assessed using Psychomotor Vigilance Task (PVT) and Wisconsin Card Sorting Test (WCST), respectively. A p value of 0.05 was considered significant. RESULTS: Sixteen senior residents (SR; ≥ PGY3) and 14 junior residents (JR; PGY1-2) completed the study. There was no difference in mental workload between LS and RALS. Within JR there was no difference in task completion time comparing LS versus RALS; however, LS was associated with impaired concentration post-task versus pre-task (PVT reaction time 306 versus 324 ms, p = 0.03), which was not observed for RALS. In contrast, amongst SR, RALS took significantly longer than LS (10.3 vs. 14.5 min, p = 0.02) and was associated with significantly worse performance on WCST (p < 0.01). CONCLUSIONS: Robotic assistance, in this setting, did not provide a technical performance advantage nor impact subjective mental workload with novice users regardless of level of surgery training. We observed a protective effect on cognitive performance offered by RALS to junior trainees with limited LS experience, yet a detrimental effect on senior trainees with greater LS ability and inadequate pre-study robotic training, suggesting that robotic consoles may be mentally taxing for robotic novices and consideration should be given to formal console training prior to initial clinical exposure.

Evaluation of quality of life, body image and surgical outcomes of robotic total laparoscopic hysterectomy and sentinel lymph node mapping in low-risk endometrial cancer patients - A Robotic Gyne Club study.

INTRODUCTION: The aims of the study were to evaluate quality of life, cosmetic results and surgical outcomes of robotic single-site and robotic multiport total laparoscopic hysterectomy with sentinel lymph node mapping in women treated for low-risk endometrial cancer. MATERIAL AND METHODS: The study is a prospective, multicenter, case-control study conducted at Ospedale Santa Chiara in Trento and Novara and Pavia University Hospitals. Seventy-six consecutive patients with a biopsy-confirmed diagnosis of low-risk endometrial cancer or atypical endometrial hyperplasia who between January 2017 and January 2019 had undergone robotic total laparoscopic hysterectomy and sentinel lymph node mapping were included. Data on surgical outcomes, quality of life and cosmetic results were prospectively collected and analyzed based on the surgical approach with robotic single-site vs robotic multiport assistance. Patients' clinical characteristics, intra-operative parameters, sentinel lymph node mapping results and postoperative findings were prospectively recorded. Clinical follow up was performed 4 weeks and 6 and 12 months after surgery. Fifty-one patients underwent a robotic multiport procedure and 25 patients a robotic single-site surgery. RESULTS: There was one significant difference between the two groups in terms of patient characteristics: mean body mass index (BMI) in the multiport group was 29 kg/m2 vs 24.8 kg/m2 in the single-site group (P value <.001). After univariate and multivariate analysis on intraoperative and postoperative findings, a shorter surgical time was observed in the single-site cohort than in the multiport group (148.7 vs 158.2 minutes, P value .0182). BMI also had a significant effect on surgical time (P = .022). No differences were seen in terms of sentinel lymph node detection: the bilateral detection rate was 96.1% for multiport (66.7% bilateral, 29.4% monolateral) and 96% for single-site (76% bilateral, 20% monolateral) procedures. No differences between the two approaches were identified with regard to postoperative complications, pain, cosmetic results or quality of life comparisons. CONCLUSIONS: For the treatment of low-risk endometrial cancer and atypical endometrial hyperplasia with total hysterectomy and sentinel lymph node mapping, the robotic single-port approach is comparable to the multiport procedure in terms of intraoperative and postoperative findings, and has an advantage in terms of shorter surgical times. Further studies are required to identify possible differences in quality of life and cosmetic results.

A cross-sectional study of current work ability after radical prostatectomy.

BACKGROUND: Work ability represents a person's subjective assessment of current ability to work compared to his lifetime best. Since many men with prostate cancer are retired, work ability represents a more relevant work measure than employment status. The primary aim was to examine the prevalence of men who had high versus moderate/poor current work ability compared to their lifetime best work ability at a mean of 3.0 years after robot-assisted laparoscopic prostatectomy. The secondary aim was to study variables associated with moderate/poor work ability at survey. METHODS: This is a questionnaire-based study of men who had robot-assisted laparoscopic prostatectomy at Oslo University Hospital, Radiumhospitalet between January 2005 and August 2010. Among them 777 responded (79%), 730 reported on current work ability, socio-demographic data, somatic and mental health, and typical adverse effects (the EPIC-26) after prostatectomy. High versus moderate/poor work ability was the primary outcome. Descriptive statistics and logistic regression analyses were applied. RESULTS: The mean age of the sample at survey was 65.5 years (SD 5.9). At survey 42% of the sample reported moderate/poor current work ability and 58% reported high work ability. In multivariable analysis older age at survey, low basic education, comorbidity, poor self-rated health, presence of depression and low EPIC-26 hormonal domain score remained significantly associated with moderate/poor work ability. CONCLUSIONS: Current work ability is a useful measure for the working capacity particularly of retired men. Socio-demographic, cancer-related, health, psychological and typical adverse effect variables were significantly associated with moderate/poor current work ability after robot-assisted laparoscopic prostatectomy, and several health and psychological variables are amenable to identification and treatment by health care providers.

A systematic review of the learning curve in robotic surgery: range and heterogeneity.

BACKGROUND: With the rapid adoption of the robotic surgery, more and more learning curve (LC) papers are being published but there is no set definition of what should constitute a rigorous analysis and represent a true LC. A systematic review of the robotic surgical literature was undertaken to determine the range and heterogeneity of parameters reported in studies assessing the LC in robotic surgery. METHODS: The search was conducted in July 2017 in PubMed. All studies reporting a LC in robotic surgery were included. 268 (25%) of the identified studies met the inclusion criteria. RESULTS: 102 (38%) studies did not define nor explicitly state the LC with appropriate evidence; 166 studies were considered for quantitative analysis. 46 different parameters of 6 different outcome domains were reported with a median of two parameters (1-8) and 1 domain (1-5) per study. Overall, three domains were only technical and three domains were both technical and clinical/patient-centered outcomes. The two most commonly reported domains were operative time [146 studies (88%)] and intraoperative outcomes [31 studies (19%)]. Postoperative outcomes [16 studies (9%)] and surgical success [11 studies (7%)] were reported infrequently. Purely technical outcomes were the most frequently used to assess LC [131 studies (79%)]. CONCLUSIONS: The outcomes reported in studies assessing LC in robotic surgery are extremely heterogeneous and are most often technical indicators of surgical performance rather than clinical and patient-centered outcomes. There is no single outcome that best represents the surgical success. A standardized multi-outcome approach to assessing LC is recommended.

Patient Perceptions of New Robotic Technologies in Clinical Restorative Dentistry.

Patient perception research has failed to focus on burgeoning technology within the dental field. Specifically, researchers have yet to focus on developing robotic technologies which are being utilized by dentists to help perform certain procedures with added precision and route mapping. The current study attempts to fill the gap created by a lack of intersection between dental technology research, consumer perceptions research, and automation research. The current research takes a two-study approach, with study 1 investigating if gender or price of the procedure affects willingness to undergo a robotic dental procedure. Study 2 further investigates this phenomenon, identifying ten separate types of dental procedures (ranging from minimally invasive to extremely invasive) to further understand consumer perceptions. Results indicate that females are less willing to undergo a robotic dental procedure, and that participants in general are more willing to undergo a procedure if it is half price than if it full price. Willingness is influenced by gender and the type of procedure being performed - participants were less willing to undergo invasive procedures such as gum surgery than noninvasive procedures such as teeth whitening. These results, and their theoretical and practical significance are discussed.

Variability and interpretation of communication taxonomy during robot-assisted surgery: do we all speak the same language?

OBJECTIVE: To investigate and analyse the different ways surgeons communicate with bedside assistants during robot-assisted surgery (RAS). METHODS: We retrospectively reviewed video and audio recordings of 26 RAS procedures (23 prostatectomies and three cystectomies). Three cameras and eight lapel microphones were used to record the operating theatre environment. We identified five common tasks and categorized them into 'specific', 'non-specific' and 'unclear' categories. We also determined the frequency, time to execute the task, inconveniences and acknowledgements associated with each category. The most efficient category was the one that took the shortest duration to accomplish and was associated with the fewest inconveniences. RESULTS: A total of 1 000 requests were made by three surgeons for six bedside assistants by three surgeons. The five identified tasks were: instrument change; clipping; suction; irrigation; and retraction. For instrument change, non-specific requests were the most frequent compared with the other categories (77% vs 18% vs 5%; P < 0.001). For suction, specific requests were the most frequently used of the three categories (73% vs 27% vs 0%; P < 0.001) and this task was associated with the fewest inconveniences (38% vs 62%; P = 0.01). For clipping, irrigation and retraction, both specific and non-specific requests were similar in terms of their frequency, action time and inconveniences. Comparing complete vs incomplete requests, incomplete requests had significantly shorter median action time (5 vs 8 s; P < 0.001) but did not significantly differ in terms of inconveniences and acknowledgement. CONCLUSION: To our knowledge, this is the first study to provide a detailed analysis of communication during RAS. It lays a foundation for standardized taxonomy to improve communication, surgical efficiency and patient safety.

Social constraints and psychological well-being after prostate cancer: A follow-up at 12 and 24 months after surgery.

OBJECTIVE: Studies indicate that social constraints (barriers to emotional expression) may be a risk factor for psychological morbidity. We aimed to investigate the association between prostate cancer-related social constraints and psychological well-being following prostate cancer surgery. METHODS: In a group of 3478 partnered patients, participating in the Laparoscopic Prostatectomy Robot Open trial, a prospective multicenter comparative study of robot-assisted laparoscopic and retropubic radical prostatectomy for prostate cancer, we used log-binomial regression analysis to investigate the links between prostate cancer-related social constraints at 3 months after surgery and psychological well-being at 12 and 24 months. RESULTS: A total of 1086 and 1093 men reported low well-being at 12 and 24 months, respectively. Prostate cancer-related social constraints by partner predicted low psychological well-being at 12 months (adjusted RR: 1.4; 95% CI, 1.1-1.9) and by others (adjusted RR: 1.9; 95% CI, 1.1-3.5). Intrusive thoughts mediated the association. CONCLUSIONS: Negative responses from the social environment, especially from partner to talking about the prostate cancer experience affected patients' psychological well-being 2 years after radical prostatectomy. Results emphasize the importance of helping patients mobilize psychosocial resources within their social network, especially among those with a lack of quality psychosocial support.

Professional networks and the alignment of individual perceptions about medical innovation.

BACKGROUND: In recent decades, the role of technology in health care organizations has become increasingly relevant because it enhances health care outcomes and the achievement of clinical goals. Extant research demonstrates that the effectiveness of a medical innovation depends largely on health care professionals' perceptions of its usefulness and impact on their activities and practices. We also know that interaction among social actors contributes to the shaping of their judgments and opinions regarding innovation. PURPOSE: This study investigated the role of professionals' social networks and social capital in the formation of similar individual perceptions about a highly innovative robotic surgical system. METHODOLOGY: We collected data from a sample of 50 professionals, including both physicians and nurses, working in three hospital wards belonging to an Italian hospital organization. Using a survey, we gathered data on professionals' demographic characteristics, the adoption and impact of the new technology, and social networks. We tested our hypotheses using a dyadic perspective and logistic regression quadratic assignment procedures. FINDINGS: Our findings document that professionals' perceptions regarding technological change were more likely to be similar when they were connected and exhibited similarity in some social capital characteristics and adoption behavior. PRACTICE IMPLICATIONS: These results have important implications for health care executives and administrators, as well as for health professionals characterized by high degrees of autonomy and for which organizational change can be affected by professional or organizational resistance.

Accessibility to surgical robot technology and prostate-cancer patient behavior for prostatectomy.

BACKGROUND: To examine how surgical robot emergence affects prostate-cancer patient behavior in seeking radical prostatectomy focusing on geographical accessibility. METHODS: In Japan, robotic surgery was approved in April 2012. Based on data in the Japanese Diagnosis Procedure Combination database between April 2012 and March 2014, distance to nearest surgical robot and interval days to radical prostatectomy (divided by mean interval in 2011: % interval days to radical prostatectomy) were calculated for individual radical prostatectomy cases at non-robotic hospitals. Caseload changes regarding distance to nearest surgical robot and robot introduction were investigated. Change in % interval days to radical prostatectomy was evaluated by multivariate analysis including distance to nearest surgical robot, age, comorbidity, hospital volume, operation type, hospital academic status, bed volume and temporal progress. RESULTS: % Interval days to radical prostatectomy became wider for distance to nearest surgical robot <30 km. When a surgical robot emerged within 30 and 10 km, the prostatectomy caseload in non-robot hospitals reduced by 13 and 18% within 6 months, respectively, while the robot hospitals gained +101% caseload (P < 0.01 for all) Multivariate analyses including 9759 open and 5052 non-robotic minimally invasive radical prostatectomies in 483 non-robot hospitals revealed a significant inverse association between distance to nearest surgical robot and % interval days to radical prostatectomy (B = -17.3% for distance to nearest surgical robot ≥30 km and -11.7% for 10-30 km versus distance to nearest surgical robot <10 km), while younger age, high-volume hospital, open-prostatectomy provider and temporal progress were other significant factors related to % interval days to radical prostatectomy widening (P < 0.05 for all). CONCLUSIONS: Robotic surgery accessibility within 30 km would make patients less likely select conventional surgery. The nearer a robot was, the faster the caseload reduction was.

Robot-assisted Surgery in Gynecologic Cancers.

Robotic-assisted surgery is a technological advancement that facilitates the application of minimally invasive techniques for complex operations in gynecologic oncology. The objective of this article was to review the literature regarding the role of robotic-assisted surgery to treat women with gynecologic cancers. The majority of publications on robotic surgery are still retrospective or descriptive in nature; however, the data for managing patients with a robotic-assisted approach show comparable, and at times improved, outcomes compared with both laparoscopy (2-dimensional) and laparotomy approaches. Robotic-assisted surgery has been used for patients with endometrial cancer and resulted in the increased use of minimally invasive surgery with improved outcomes compared with laparotomy and partially with laparoscopy. This has been shown in large cohorts of patients as well as in obese patients in whom the complication rates have significantly decreased. For early cervical cancer, robotic radical hysterectomy seems to be safe and feasible and to be preferable to laparotomy with seemingly comparable oncologic outcomes. Robotic-assisted surgery and conventional laparoscopy to stage women with early-stage ovarian cancer seem to have similar surgical and oncologic outcomes, with a shorter learning curve for robotic-assisted surgery. However, robotic-assisted surgery appears to be more expensive than laparotomy and traditional laparoscopy. In conclusion, robotic-assisted surgery appears to facilitate the surgical approach for complex operations to treat women with gynecologic cancers. Although randomized controlled trials are lacking to further elucidate the equivalence of robot-assisted surgery with conventional methods in terms of oncologic outcome and patients' quality of life, the technology appears to be safe and effective and could offer a minimally invasive approach to a much larger group of patients.

Transfer and priming of surgical skills across minimally invasive surgical platforms.

BACKGROUND: Robot-assisted laparoscopic surgery (RALS) uses 3-dimensional visualization and wristed instruments that provide more degrees of freedom than rigid traditional laparoscopic (TLS) instrumentation. These features have been touted to improve accuracy and efficiency during surgical task performance. Little is known, however, about the transferability of skills between the two platforms or whether task performance on one platform primes surgeons for task performance on the other. METHODS: Twenty-six subjects naïve to RALS were recruited to perform three Fundamentals of Laparoscopic Surgery tasks on both TLS and RALS platforms: peg transfer, pattern cutting (PC), and intracorporeal suturing. All tasks were performed within Fundamentals of Laparoscopic Surgery testing parameters and repeated three times by each subject on each platform. Platform and task order were randomized. Errors in task performance were defined as drops in the peg transfer task, faults 5 mm or more from the defined pattern during PC, and faults greater than 1 mm in suture placement from the defined points in intracorporeal suturing. Mean completion times and mean errors per trial (EPT) were calculated for each task on both platforms. Results were compared between those who performed TLS first (LF) and those who performed RALS first (RF) using unpaired Student's t-test (P < 0.05 considered statistically significant). RESULTS: No statistically significant differences in task completion time were noted between the LF and RF groups. RF subjects had fewer errors during robotic PC than LF subjects (1.02 EPT versus 1.86 EPT, respectively; P = 0.02). No other differences in task quality were noted. CONCLUSIONS: In surgeon's naïve to RALS, there is no evidence that skills acquired on RALS or TLS platforms are transferable to the other platform or that performing tasks on one platform primes a subject for task performance on the other. Performing TLS PC may have had a negative impact on subsequent RALS PC performance. These findings suggest that distinct programs for skills acquisition are necessary for both the TLS and RALS platforms.

Pre-Operative Education Classes Prior to Robotic Prostatectomy Benefit Both Patients and Clinicians.

As part of a process improvement initiative, we designed, implemented, and assessed the impact of pre-surgical education classes for patients scheduled to undergo robotic prostatectomy. Our aim was to both enhance patient access to important procedural information related to their surgery, and also limit the need for the repeated dissemination of information during patient calls to the office.

Relax, it's just laparoscopy! A prospective randomized trial on heart rate variability of the surgeon in robot-assisted versus conventional laparoscopic cholecystectomy.

BACKGROUND: Laparoscopic surgery might be beneficial for the patient, but it imposes increased physical and mental strain on the surgeon. Robot-assisted laparoscopic surgery addresses some of the laparoscopic drawbacks and may potentially reduce mental strain. This could reduce the risk of surgeon's fatigue, mishaps and strain-induced illnesses, which may eventually improve the safety of laparoscopic surgical procedures. METHODS: To test this hypothesis, a randomized study was performed, comparing both heart rate and heart rate variability (HRV) of the surgeon as a measure of total and mental strain, respectively, during conventional and robot-assisted laparoscopic cholecystectomy. RESULTS: Both heart rate and HRV (the low-frequency band/high-frequency band ratio) were significantly decreased when using robotic assistance. CONCLUSIONS: These data suggest the use of the daVinci® Surgical System leads to less physical and mental strain of the surgeon during surgery. However, assessing mental strain by means of HRV is cumbersome since there is no clear cutoff point or scale for maximum tolerated strain levels and its related effects on surgeon's health.

Knowledge, attitude, and perception of robotic-assisted surgery among the general population in Saudi Arabia: a cross-sectional study.

Minimally invasive surgery (MIS) has revolutionized surgical practices, with robotic-assisted surgery (RAS) significantly advancing. However, the understanding and acceptance of RAS vary, impacting its widespread adoption. This study aims to assess Saudi Arabians' attitudes and comprehension of RAS, which is crucial for promoting its integration into surgical procedures. A cross-sectional study was conducted in various Saudi Arabian cities. A total of 1449 participants were included, while participants with cognitive issues were excluded. Demographic information, knowledge, technology experience, attitudes, and perceptions about RAS were collected using an online self-administered questionnaire. Data were analyzed using descriptive and inferential statistics. Of the participants, 51.1% demonstrated awareness of RAS, mainly through social media (36.9%). Factors influencing awareness included gender, education, income, occupation, computer literacy, and technology comfort. Gender disparities were evident in attitudes and perceptions toward RAS. Concerns about RAS included robot malfunction (62.0%), surgical errors (45.4%), and surgeon competency (44.7%). 36.4% of the participants believe RAS is faster, 29.9% believe RAS is less painful, and 25.3% believe RAS has fewer complications. Positive perceptions encompassed the belief that robot-using surgeons are more skilled (44.5%) and hospitals offering RAS are better (54.3%). Notably, 47.7% expressed willingness to consider RAS as a treatment option. The study underscores the significance of promoting awareness and informed decisions to ensure the successful integration of RAS in surgical practices. Addressing concerns and misconceptions and enhancing public comprehension are pivotal for facilitating informed decision-making and fostering RAS acceptance within Saudi Arabia's surgical landscape.

Intraoperative teamwork and occupational stress during robot-assisted surgery: An observational study.

Robot-assisted surgery (RAS) differs from traditional OR set-ups in several ways such as operation of technology and obstructed team communication that potentially affect surgical staff's stress experiences. The current study investigates the effects of key intraoperative job demands and resources on mental workload and perceived stress in RAS. We focused on the role of intraoperative teamwork as a resource that potentially reduces occupational stress. Combining standardized expert observations in the OR with healthcare providers' self-reports, the study involved two types of robot-assisted, urological interventions. The sample consisted of 73 observed surgeries and included 242 post-operative surveys on perceived stress and mental workload from surgeons and surgical nurses. Multilevel regression analyses reveal differential effects for stress and workload. Importantly, whereas better surgical teamwork was associated with lower stress, it was unrelated to workload. Our findings provide a nuanced picture of occupational stress in RAS, particularly regarding the role of intraoperative teamwork.

Utilizing deep neural networks and electroencephalogram for objective evaluation of surgeon's distraction during robot-assisted surgery.

OBJECTIVE: To develop an algorithm for objective evaluation of distraction of surgeons during robot-assisted surgery (RAS). MATERIALS AND METHODS: Electroencephalogram (EEG) of 22 medical students was recorded while performing five key tasks on the robotic surgical simulator: Instrument Control, Ball Placement, Spatial Control II, Fourth Arm Tissue Retraction, and Hands-on Surgical Training Tasks. All students completed the Surgery Task Load Index (SURG-TLX), which includes one domain for subjective assessment of distraction (scale: 1-20). Scores were divided into low (score 1-6, subjective label: 1), intermediate (score 7-12, subjective label: 2), and high distraction (score 13-20, subjective label: 3). These cut-off values were arbitrarily considered based on a verbal assessment of participants and experienced surgeons. A Deep Convolutional Neural Network (CNN) algorithm was trained utilizing EEG recordings from the medical students and used to classify their distraction levels. The accuracy of our method was determined by comparing the subjective distraction scores on SURG-TLX and the results from the proposed classification algorithm. Also, Pearson correlation was utilized to assess the relationship between performance scores (generated by the simulator) and distraction (Subjective assessment scores). RESULTS: The proposed end-to-end model classified distraction into low, intermediate, and high with 94%, 89%, and 95% accuracy, respectively. We found a significant negative correlation (r = -0.21; p = 0.003) between performance and SURG-TLX distraction scores. CONCLUSIONS: Herein we report, to our knowledge, the first objective method to assess and quantify distraction while performing robotic surgical tasks on the robotic simulator, which may improve patient safety. Validation in the clinical setting is required.

Building a predictive model of U.S. patient willingness to undergo robotic surgery.

Prior research regarding robotic surgery (RS) has largely focused on the engineering or medical aspects of these tools. A few studies have examined consumer opinions toward, or willingness to use, robotic surgeons; however, no study to date has examined what type of person would be willing to undergo RS. Across two studies, the current research fills this gap by building both a descriptive and predictive regression model used to predict what type of user would be willing to undergo RS. To build the descriptive model, 1324 potential patients were asked a series of questions about demographics, attitudes, opinions, and personalities. Results indicate that perceived value, familiarity, wariness of new technologies, fear of surgery, openness, anger, fear, and happiness are all significant predictors of willingness to undergo RS. A regression equation was developed and then used to predict scores in a second study with 1335 potential patients. The scores from both studies were compared for model fit. Several methods were used to validate the regression model, including correlational analyses, a t test, and calculation of the cross-validity coefficient. All three stringent tests showed strong model fit, explaining 62% of the variance in the model. These findings have both practical and theoretical values to the field and can be used to identify early adopters of this advanced medical technology.

Patient Satisfaction and Regret After Robot-assisted Radical Prostatectomy: A Decision Regret Analysis.

OBJECTIVE: To assess treatment satisfaction and decision regret post robot-assisted radical prostatectomy (RARP) and correlate these with clinical, demographic and quality of life indicators. Our study took place at a high-volume United Kingdom center and patients were assessed at a minimum of 18 months postsurgery. METHODS: Patients who underwent RARP between June 2011 and May 2016 were invited to participate through mailed questionnaires. A total of 207 patients formed our cohort. The questionnaires included European Organization for Research and Treatment of Cancer Quality of Life of Cancer patients 30 and PR25 modules, sexual health inventory in men and Likert decisional regret scale. A Decisional Regret Scale score of >15 was used to define an outcome of high decision regret. RESULTS: The mean patient age was 63 years and the mean duration of follow up was 36 months. Of the 106 responders, 51 (48%) were fully satisfied with the decision to undergo RARP and 32 (30%) recorded high regret. The mean Decisional Regret Scale score was 11.3. High decision regret associated with the length of time from RARP to questionnaire administration, higher prostate specific quality of life symptom scores and lower sexual and erectile function scores. CONCLUSION: Our study represents the first contemporary United Kingdom series assessing decision regret following the management of localised prostate cancer with RARP. Higher regret was seen in one third of patients and was associated with worse disease-specific quality of life, sexual and erectile function measures. To minimize regret, collaborative and detailed discussion should take place pre-operatively when counselling patients about RARP. The potential longevity and impact on quality of life of these side effects should be made clear.
