European Association for Endoscopic Surgery (EAES) consensus on Indocyanine Green (ICG) fluorescence-guided surgery.

BACKGROUND: In recent years, the use of Indocyanine Green (ICG) fluorescence-guided surgery during open and laparoscopic procedures has exponentially expanded across various clinical settings. The European Association of Endoscopic Surgery (EAES) initiated a consensus development conference on this topic with the aim of creating evidence-based statements and recommendations for the surgical community. METHODS: An expert panel of surgeons has been selected and invited to participate to this project. Systematic reviews of the PubMed, Embase and Cochrane libraries were performed to identify evidence on potential benefits of ICG fluorescence-guided surgery on clinical practice and patient outcomes. Statements and recommendations were prepared and unanimously agreed by the panel; they were then submitted to all EAES members through a two-rounds online survey and results presented at the EAES annual congress, Barcelona, November 2021. RESULTS: A total of 18,273 abstracts were screened with 117 articles included. 22 statements and 16 recommendations were generated and approved. In some areas, such as the use of ICG fluorescence-guided surgery during laparoscopic cholecystectomy, the perfusion assessment in colorectal surgery and the search for the sentinel lymph nodes in gynaecological malignancies, the large number of evidences in literature has allowed us to strongly recommend the use of ICG for a better anatomical definition and a reduction in post-operative complications. CONCLUSIONS: Overall, from the systematic literature review performed by the experts panel and the survey extended to all EAES members, ICG fluorescence-guided surgery could be considered a safe and effective technology. Future robust clinical research is required to specifically validate multiple organ-specific applications and the potential benefits of this technique on clinical outcomes.

Implementing structured team debriefing using a Black Box in the operating room: surveying team satisfaction.

BACKGROUND: Surgical safety may be improved using a medical data recorder (MDR) for the purpose of postoperative team debriefing. It provides the team in the operating room (OR) with the opportunity to look back upon their joint performance objectively to discuss and learn from suboptimal situations or possible adverse events. The aim of this study was to investigate the satisfaction of the OR team using an MDR, the OR Black Box®, in the OR as a tool providing output for structured team debriefing. METHODS: In this longitudinal survey study, 35 gastro-intestinal laparoscopic operations were recorded using the OR Black Box® and the output was subsequently debriefed with the operating team. Prior to study, a privacy impact assessment was conducted to ensure alignment with applicable legal and regulatory requirements. A structured debrief model and an OR Back Box® performance report was developed. A standardized survey was used to measure participant's satisfaction with the team debriefing, the debrief model used and the performance report. Factor analysis was performed to assess the questionnaire's quality and identified contributing satisfaction factors. Multivariable analysis was performed to identify variables associated with participants' opinions. RESULTS: In total, 81 team members of various disciplines in the OR participated, comprising 35 laparoscopic procedures. Mean satisfaction with the OR Black Box® performance report and team debriefing was high for all 3 identified independent satisfaction factors. Of all participants, 98% recommend using the OR Black Box® and the outcome report in team debriefing. CONCLUSION: The use of an MDR in the OR for the purpose of team debriefing is considered to be both beneficial and important. Team debriefing using the OR Black Box® outcome report is highly recommended by 98% of team members participating.

Legal perspectives on black box recording devices in the operating environment.

BACKGROUND: A video and medical data recorder in the operating theatre is possible, but concerns over privacy, data use and litigation have limited widespread implementation. The literature on legal considerations and challenges to overcome, and guidelines related to use of data recording in the surgical environment, are presented in this narrative review. METHODS: A review of PubMed and Embase databases and Cochrane Library was undertaken. International jurisprudence on the topic was searched. Practice recommendations and legal perspectives were acquired based on experience with implementation and use of a video and medical data recorder in the operating theatre. RESULTS: After removing duplicates, 116 citations were retrieved and abstracts screened; 31 articles were assessed for eligibility and 20 papers were finally included. According to the European General Data Protection Regulation and US Health Insurance Portability and Accountability Act, researchers are required to make sure that personal data collected from patients and healthcare professionals are used fairly and lawfully, for limited and specifically stated purposes, in an adequate and relevant manner, kept safe and secure, and stored for no longer than is absolutely necessary. Data collected for the sole purpose of healthcare quality improvement are not required to be added to the patient's medical record. CONCLUSION: Transparency on the use and purpose of recorded data should be ensured to both staff and patients. The recorded video data do not need to be used as evidence in court if patient medical records are well maintained. Clear legislation on data responsibility is needed to use the medical recorder optimally for quality improvement initiatives.

ANTECEDENTES: Es posible instalar un sistema de video y grabación de datos médicos en el quirófano, pero su implementación se ha visto limitada por las dudas relativas a la privacidad, uso de datos y aspectos de litigio. Estas dudas deberían superarse, motivo por el que en este trabajo se proponen unas guías sobre el uso de sistemas de registro en el ambiente quirúrgico. MÉTODOS: Se realizó una revisión en las bases de datos Pubmed y Embase y de la Biblioteca Cochrane. Se buscó la jurisprudencia internacional sobre el tema. Se establecieron unas recomendaciones prácticas y de las perspectivas legales adquiridas a través de la experiencia de la implementación y el uso de sistemas de video y registro de datos médicos en el quirófano. RESULTADOS: Se obtuvieron 116 referencias, de las que una vez eliminadas las duplicadas (n = 5) y revisados los resumenes, 31 artículos cumplían los criterios de eligibilidad. En el estudio final se incluyeron 20 artículos. De acuerdo con la Ley Orgánica de Protección de Datos (General Data Protection Regulation, GDRP) y la Ley de Transferencia y Responsabilidad de Seguro Médico (Health Insurance Portability and Accountability Act, HIPAA), los investigadores deben asegurar que los datos personales recopilados pertenecientes a los pacientes y profesionales de la salud se utilicen de manera justa y legal, con fines definidos y bien establecidos, de manera adecuada y relevante, y mantenidos a resguardo y almacenados no más tiempo del estrictamente necesario. No es necesario que los datos recopilados con el único propósito de mejorar la calidad de la atención médica se agreguen a la historia clínica del paciente. CONCLUSIÓN: Se debe asegurar por parte del personal sanitario como del paciente, la transparencia tanto en la utilización como en el objetivo de los datos almacenados. Los datos registrados en video no es necesario que sean usados como evidencia en procesos judiciales si la historia clínica de los pacientes cumple los estandares establecidos. Se precisa una legislación clara sobre la responsabilidad de los datos para la utilización óptima de los registros médicos en las iniciativas de mejora de la calidad.

Improving enhanced recovery after surgery (ERAS): ERAS APPtimize study protocol, a randomized controlled trial investigating the effect of a patient-centred mobile application on patient participation in colorectal surgery.

BACKGROUND: Perioperative care in colorectal surgery is systematically defined in the Enhanced Recovery After Surgery (ERAS) protocol. The ERAS protocol improves perioperative care in a multimodal way to enhance early and safe release from the hospital. Adequate compliance to the elements of the ERAS protocol is multifactorial. There are still opportunities to improve compliance of the protocol by actively involving the patient. The main objective of this study is to investigate whether compliance of selected items in the ERAS protocol can be improved through actively involving patients in the ERAS care pathway through the use of a patient-centred mobile application. METHODS: A multicentre randomized controlled trial will be conducted. Patients undergoing elective colorectal surgery, who are 18 years or older and in possession of an eligible smartphone, will be included. Patients assigned to the intervention group will install a patient-centred mobile application to be guided through the ERAS care pathway. Patients in the control group will receive care as usual. Both groups will wear an activity tracker. The primary outcome is overall compliance to selected active elements of the ERAS protocol, as registered by the patient. Secondary outcomes include Patient Reported Outcome Measures (PROMs) such as health-related quality of life, physical activity, and patient satisfaction of received care. Care-related outcomes, such as length of hospital stay, number of complications, re-intervention, and readmission rates, will also be assessed. RESULTS: The enrolment of patients will start in the second quarter of 2019. Data collection had not begun by the time this protocol was submitted. CONCLUSION: We hypothesize that by providing patients with a patient-centred mobile application, compliance to the active elements of ERAS protocol can be improved, resulting in an increased health-related quality of life, physical activity, and patient satisfaction. TRIAL REGISTRATION: Netherlands Trial Register, NTR7314 , prospectively registered on the 9th of November 2017 ( http://www.trialregister.nl ).

Adults with congenital heart disease: ready for mobile health?

PURPOSE: Mobile health (mHealth) could improve the outcome of grown-up patients with congenital heart disease (GUCH) and reduce their emergency care utilisation. Inappropriate use of mHealth, however, can lead to data overload for professionals and unnecessary data collection for patients, increasing the burden for both. We aimed to determine the clinical characteristics of patients with high emergency care utilisation and to test whether these patients were willing to start using mHealth. METHODS: Clinical characteristics and emergency care utilisation of consecutive GUCH patients who visited one of the two participating cardiologists at the outpatient clinic of the Academic Medical Centre in Amsterdam were studied retrospectively. All patients were approached to fill in an mHealth questionnaire. A frequency of three or more emergency visits in 5 years was defined as high emergency care utilisation. RESULTS: In total, 202 consecutive GUCH patients who visited one of the two participating cardiologists were studied. Median age was 41 years, 47% were male, and 51% were symptomatic. In the previous 5 years, 134 emergency visits were identified. Of all patients, 8% had high emergency care utilisation. High emergency care utilisation was associated with patients being symptomatic, using antiarrhythmic drugs or diuretics. In total, 75% of all patients with high emergency care utilisation were willing to start using mHealth. CONCLUSION: GUCH patients who are symptomatic, those on antiarrhythmic drug therapy and those on diuretics are suitable candidates for enrolment in future mHealth initiatives because of both high care utilisation and high motivation to start using mHealth.

First real-world experience with mobile health telemonitoring in adult patients with congenital heart disease.

BACKGROUND: Arrhythmias and heart failure are common and invalidating sequelae in adult patients with congenital heart disease (CHD). Mobile health (m-Health) enables daily monitoring and a timely response that might prevent deterioration. We present an observational prospective registry to evaluate feasibility of an m­Health telemonitoring program for managing arrhythmia, heart failure and blood pressure in symptomatic adults with CHD. METHODS: Symptomatic adult patients with CHD are enrolled in an m­Health telemonitoring program, which evaluates single-lead ECG, blood pressure and weight measurements. In case of symptoms extra measurements could be performed. Data are collected by mobile apps, matched with individualised thresholds. Patients are contacted if thresholds were exceeded or if arrhythmias were found, for treatment adjustments or reassurance. Data on emergency care utilisation, hospitalisation and patient-reported outcome measures are used to assess quality of life and self-management. RESULTS: 129 symptomatic CHD patients were invited to participate, 55 participated. Reasons for refusing consent included too time consuming to participate in research (30) and to monitor vital signs (14). At baseline 22 patients were in New York Heart Association class ≥ II heart failure, 43 patients had palpitations or documented arrhythmias, and 8 had hypertension. Mean follow-up was 3.0 months, one patient dropped out, and adherence was 97%. CONCLUSION: The first results indicate that this program is feasible with high adherence.

Systematic review on the effectiveness of augmented reality applications in medical training.

BACKGROUND: Computer-based applications are increasingly used to support the training of medical professionals. Augmented reality applications (ARAs) render an interactive virtual layer on top of reality. The use of ARAs is of real interest to medical education because they blend digital elements with the physical learning environment. This will result in new educational opportunities. The aim of this systematic review is to investigate to which extent augmented reality applications are currently used to validly support medical professionals training. METHODS: PubMed, Embase, INSPEC and PsychInfo were searched using predefined inclusion criteria for relevant articles up to August 2015. All study types were considered eligible. Articles concerning AR applications used to train or educate medical professionals were evaluated. RESULTS: Twenty-seven studies were found relevant, describing a total of seven augmented reality applications. Applications were assigned to three different categories. The first category is directed toward laparoscopic surgical training, the second category toward mixed reality training of neurosurgical procedures and the third category toward training echocardiography. Statistical pooling of data could not be performed due to heterogeneity of study designs. Face-, construct- and concurrent validity was proven for two applications directed at laparoscopic training, face- and construct validity for neurosurgical procedures and face-, content- and construct validity in echocardiography training. In the literature, none of the ARAs completed a full validation process for the purpose of use. CONCLUSION: Augmented reality applications that support blended learning in medical training have gained public and scientific interest. In order to be of value, applications must be able to transfer information to the user. Although promising, the literature to date is lacking to support such evidence.

Mobile health in adults with congenital heart disease: current use and future needs.

OBJECTIVE: Many adults with congenital heart disease (CHD) are affected lifelong by cardiac events, particularly arrhythmias and heart failure. Despite the care provided, the cardiac event rate remains high. Mobile health (mHealth) brings opportunities to enhance daily monitoring and hence timely response in an attempt to improve outcome. However, it is not known if adults with CHD are currently using mHealth and what type of mHealth they may need in the near future. METHODS: Consecutive adult patients with CHD who visited the outpatient clinic at the Academic Medical Center in Amsterdam were asked to fill out questionnaires. Exclusion criteria for this study were mental impairment or inability to read and write Dutch. RESULTS: All 118 patients participated (median age 40 (range 18-78) years, 40 % male, 49 % symptomatic) and 92 % owned a smartphone. Whereas only a small minority (14 %) of patients used mHealth, the large majority (75 %) were willing to start. Most patients wanted to use mHealth in order to receive more information on physical health, and advice on progression of symptoms or signs of deterioration. Analyses on age, gender and complexity of defect showed significantly less current smartphone usage at older age, but no difference in interest or preferences in type of mHealth application for the near future. CONCLUSION: The relatively young adult CHD population only rarely uses mHealth, but the majority are motivated to start using mHealth. New mHealth initiatives are required in these patients with a chronic condition who need lifelong surveillance in order to reveal if a reduction in morbidity and mortality and improvement in quality of life can be achieved.

Training situational awareness to reduce surgical errors in the operating room.

BACKGROUND: Surgical errors result from faulty decision-making, misperceptions and the application of suboptimal problem-solving strategies, just as often as they result from technical failure. To date, surgical training curricula have focused mainly on the acquisition of technical skills. The aim of this review was to assess the validity of methods for improving situational awareness in the surgical theatre. METHODS: A search was conducted in PubMed, Embase, the Cochrane Library and PsycINFO using predefined inclusion criteria, up to June 2014. All study types were considered eligible. The primary endpoint was validity for improving situational awareness in the surgical theatre at individual or team level. RESULTS: Nine articles were considered eligible. These evaluated surgical team crisis training in simulated environments for minimally invasive surgery (4) and open surgery (3), and training courses focused at training non-technical skills (2). Two studies showed that simulation-based surgical team crisis training has construct validity for assessing situational awareness in surgical trainees in minimally invasive surgery. None of the studies showed effectiveness of surgical crisis training on situational awareness in open surgery, whereas one showed face validity of a 2-day non-technical skills training course. CONCLUSION: To improve safety in the operating theatre, more attention to situational awareness is needed in surgical training. Few structured curricula have been developed and validation research remains limited. Strategies to improve situational awareness can be adopted from other industries.

Education in wrist arthroscopy: past, present and future.

PURPOSE: Arthroscopy has assumed an important place in wrist surgery. It requires specific operative skills that are now mainly acquired in the operating room. In other fields of endoscopic surgery, e-learning and virtual reality (VR) have introduced new perspectives in teaching skills. This leads to the following research question: Could the current way of teaching wrist arthroscopy skills be supported using new educational media, such as e-learning and simulator training? METHOD: The literature was searched for available methods of teaching endoscopic skills. Articles were assessed on the evidence of validity. In addition, a survey was sent to all members of the European Wrist Arthroscopy Society (EWAS) to find out whether hand surgeons express a need to embrace modern educational tools such as e-learning or simulators for training of wrist arthroscopy skills. RESULTS: This study shows that the current way of teaching wrist arthroscopy skills can be supported using new educational media, such as e-learning and simulator training. Literature indicates that e-learning can be a valuable tool for teaching basic knowledge of arthroscopy and supports the hypothesis that the use of virtual reality and simulators in training enhances operative skills in surgical trainees. This survey indicates that 55 out of 65 respondents feel that an e-learning program would be a valuable asset and 62 out of the 65 respondents are positive on the additional value of wrist arthroscopy simulator in training. CONCLUSION: Study results support the need and relevance to strengthen current training of wrist arthroscopy using e-learning and simulator training. LEVEL OF EVIDENCE: V.

Upscaling telemonitoring in Dutch University Medical Centres: A baseline measurement.

INTRODUCTION AND OBJECTIVE: The Dutch university medical centres (UMC's) are on the forefront when it comes to validation, implementation and research of telemonitoring. To aid the UMC's in their effort, the Dutch Government has supported the UMC's by fostering the 'Citrien eHealth program'. This program aims at nationwide implementation and upscaling of telemonitoring via a collaborative network. To quantify the success of this program, this study aims to provide insights into the current adoption of telemonitoring by health care professionals (HCP) within Dutch UMC's. METHODS: Based on the evaluation framework as adapted from the Normalization Process Theory (NPT) a cross-sectional study was conducted in all Dutch UMC's. Thirty healthcare professionals (HCPs) per UMC were invited to complete the 23-item Normalization MeAsure Development (NoMAD) questionnaire, a tool to assess the degree of normalisation of telemonitoring. RESULTS: The over-all response rate was 52.4% (124/240). Over 80% of respondents agreed or strongly agreed that they understand how telemonitoring affects the nature of their work, with a mean score of 1.49 (N = 117, SD 0.74). HCPs reported to believe telemonitoring will become a normal part of their work in the near future (N = 124, mean = 8.67, SD = 1.38). Using the Wilcoxon signed-rank test, the difference between current practise and future use of telemonitoring predicts to be statistically significant (Z =  - 7.505, p ≤ 0.001). Mean scores for appropriate training and sufficient resources are relatively low (2.39 and 2.70 respectively), indicating a barrier for collective action. CONCLUSION: This is the first study to assess the implementation of telemonitoring as standard practise across Dutch UMCs. The HCPs in this study are the frontrunners, believing that telemonitoring will become standard practise in the future despite the fact that it is currently not. Based on the results of this study, both educational and implementation strategies including practical skills training are highly recommended in order to scale up telemonitoring widely.

Systematic review of serious games for medical education and surgical skills training.

BACKGROUND: The application of digital games for training medical professionals is on the rise. So-called 'serious' games form training tools that provide a challenging simulated environment, ideal for future surgical training. Ultimately, serious games are directed at reducing medical error and subsequent healthcare costs. The aim was to review current serious games for training medical professionals and to evaluate the validity testing of such games. METHODS: PubMed, Embase, the Cochrane Database of Systematic Reviews, PsychInfo and CINAHL were searched using predefined inclusion criteria for available studies up to April 2012. The primary endpoint was validation according to current criteria. RESULTS: A total of 25 articles were identified, describing a total of 30 serious games. The games were divided into two categories: those developed for specific educational purposes (17) and commercial games also useful for developing skills relevant to medical personnel (13). Pooling of data was not performed owing to the heterogeneity of study designs and serious games. Six serious games were identified that had a process of validation. Of these six, three games were developed for team training in critical care and triage, and three were commercially available games applied to train laparoscopic psychomotor skills. None of the serious games had completed a full validation process for the purpose of use. CONCLUSION: Blended and interactive learning by means of serious games may be applied to train both technical and non-technical skills relevant to the surgical field. Games developed or used for this purpose need validation before integration into surgical teaching curricula.

Training and learning robotic surgery, time for a more structured approach: a systematic review.

BACKGROUND: Robotic assisted laparoscopic surgery is growing rapidly and there is an increasing need for a structured approach to train future robotic surgeons. OBJECTIVES: To review the literature on training and learning strategies for robotic assisted laparoscopic surgery. SEARCH STRATEGY: A systematic search of MEDLINE, EMBASE, the Cochrane Library and the Journal of Robotic Surgery was performed. SELECTION CRITERIA: We included articles concerning training, learning, education and teaching of robotic assisted laparoscopic surgery in any specialism. DATA COLLECTION AND ANALYSIS: Two authors independently selected articles to be included. We categorised the included articles into: training modalities, learning curve, training future surgeons, curriculum design and implementation. MAIN RESULTS: We included 114 full text articles. Training modalities such as didactic training, skills training (dry lab, virtual reality, animal or cadaver models), case observation, bedside assisting, proctoring and the mentoring console can be used for training in robotic assisted laparoscopic surgery. Several training programmes in general and specific programmes designed for residents, fellows and surgeons are described in the literature. We provide guidelines for development of a structured training programme. AUTHORS' CONCLUSIONS: Robotic surgical training consists of system training and procedural training. System training should be formally organised and should be competence based, instead of time based. Virtual reality training will play an import role in the near future. Procedural training should be organised in a stepwise approach with objective assessment of each step. This review aims to facilitate and improve the implementation of structured robotic surgical training programmes.

Laparoscopic skills training using inexpensive box trainers: which exercises to choose when constructing a validated training course.

OBJECTIVE: To obtain face and construct validity for a new training course to be used in any type of box/video trainer and to give a comprehensive overview of validated exercises for box/video training. DESIGN: Cross-sectional study. SETTING: University Medical Centre. POPULATION: Students, residents and consultants. METHODS: Participants (n = 42) were divided into three groups according to their laparoscopic experience: 'Novices' (n = 18), 'Intermediates' (n = 14) and 'Experts' (n = 10). A laparoscopic training course consisting of six exercises was constructed. To emphasise precision, a penalty score was added. Every participant performed two repetitions of the exercises; total score per exercise was calculated. To determine face validity, participants filled in a questionnaire after completion of the exercises. An evidence-based literature search for validated box/video trainer exercises was performed. MAIN OUTCOME MEASURES: Face and construct validity. RESULTS: The mean score of the 'experts' was set as the training target. Total scores appeared to be positively correlated with individual's laparoscopic experience. The overall score and the score for each exercise were significantly higher in the intermediate and expert groups when compared with the novice group (P ≤ 0.001). All participants completed the questionnaire. The overall assessment of the exercises was considered to be good. The course was found to be most appropriate for training residents year 1-3. CONCLUSION: Face and construct validity for an inexpensive course for box/video training was established. A comprehensive and practical overview of all validated and published exercises for box/video trainers is provided to facilitate an inexpensive, but optimal and tailored selection for training purposes.

Emergency upscaling of video consultation during the COVID-19 pandemic: Contrasting user experience with data insights from the electronic health record in a large academic hospital.

BACKGROUND: Video consultation (VC) has been scaled up at our academic centre attempting to facilitate and accommodate patient-provider interaction in times of social distancing during the recent and ongoing COVID-19 pandemic. OBJECTIVES: This study evaluates qualitative outcomes with data insights from the electronic health record, to contrast satisfaction outcomes with the actual use of VC. METHODS: Healthcare providers and patients using VC during the COVID-19 pandemic at a large academic centre in the Netherlands were surveyed for user satisfaction and experiences with VC. In addition, quantitative technical assessment was performed using data related to VC from the EHR record. RESULTS: In total, 1,027/4,443 patients and 87/166 healthcare providers completed their online questionnaire. Users rated the use of VC during a pandemic with an average score of 8.3/10 and 7.6/10 respectively. Both groups believed the use of VC was a good solution to continue the provision of healthcare during this pandemic. The use of VC increased from 92 in March 2020 to 837 in April 2020. CONCLUSION: This study strongly signals that VC is an important modality in futureproofing outpatient care during and beyond pandemic times. Further development in end-user technology is needed for EHR integrated VC solutions. Guidelines needs to be developed advising both patients and healthcare providers. Such guidelines should not solely focus on technical implementation and troubleshooting, but must also consider important aspects such as digital health literacy, patient and provider authentication, privacy and ethics.

Transatlantic comparison of the competence of surgeons at the start of their professional career.

BACKGROUND: Although the objective in European Union and North American surgical residency programmes is similar-to train competent surgeons-residents' working hours are different. It was hypothesized that practice-ready surgeons with more working hours would perform significantly better than those being educated within shorter working week curricula. METHODS: At each test site, 21 practice-ready candidate surgeons were recruited. Twenty qualified Canadian and 19 qualified Dutch surgeons served as examiners. At both sites, three validated outcome instruments assessing multiple aspects of surgical competency were used. RESULTS: No significant differences were found in performance on the integrative and cognitive examination (Comprehensive Integrative Puzzle) or the technical skills test (Objective Structured Assessment of Technical Skill; OSATS). A significant difference in outcome was observed only on the Patient Assessment and Management Examination, which focuses on skills needed to manage patients with complex problems (P < 0.001). A significant interaction was observed between examiner and candidate origins for both task-specific OSATS checklist (P = 0.001) and OSATS global rating scale (P < 0.001) scores. CONCLUSION: Canadian residents, serving many more working hours, perform equivalently to Dutch residents when assessed on technical skills and cognitive knowledge, but outperformed Dutch residents in skills for patient management. Secondary analyses suggested that cultural differences influence the assessment process significantly.

The SEP "robot": a valid virtual reality robotic simulator for the Da Vinci Surgical System?

The aim of the study was to determine if the concept of face and construct validity may apply to the SurgicalSim Educational Platform (SEP) "robot" simulator. The SEP robot simulator is a virtual reality (VR) simulator aiming to train users on the Da Vinci Surgical System. To determine the SEP's face validity, two questionnaires were constructed. First, a questionnaire was sent to users of the Da Vinci system (reference group) to determine a focused user-group opinion and their recommendations concerning VR-based training applications for robotic surgery. Next, clinical specialists were requested to complete a pre-tested face validity questionnaire after performing a suturing task on the SEP robot simulator. To determine the SEP's construct validity, outcome parameters of the suturing task were compared, for example, relative to participants' endoscopic experience. Correlations between endoscopic experience and outcome parameters of the performed suturing task were tested for significance. On an ordinal five-point, scale the average score for the quality of the simulator software was 3.4; for its hardware, 3.0. Over 80% agreed that it is important to train surgeons and surgical trainees to use the Da Vinci. There was a significant but marginal difference in tool tip trajectory (p = 0.050) and a nonsignificant difference in total procedure time (p = 0.138) in favor of the experienced group. In conclusion, the results of this study reflect a uniform positive opinion using VR training in robotic surgery. Concepts of face and construct validity of the SEP robotic simulator are present; however, these are not strong and need to be improved before implementation of the SEP robotic simulator in its present state for a validated training curriculum to be successful .

The value of haptic feedback in conventional and robot-assisted minimal invasive surgery and virtual reality training: a current review.

BACKGROUND: Virtual reality (VR) as surgical training tool has become a state-of-the-art technique in training and teaching skills for minimally invasive surgery (MIS). Although intuitively appealing, the true benefits of haptic (VR training) platforms are unknown. Many questions about haptic feedback in the different areas of surgical skills (training) need to be answered before adding costly haptic feedback in VR simulation for MIS training. This study was designed to review the current status and value of haptic feedback in conventional and robot-assisted MIS and training by using virtual reality simulation. METHODS: A systematic review of the literature was undertaken using PubMed and MEDLINE. The following search terms were used: Haptic feedback OR Haptics OR Force feedback AND/OR Minimal Invasive Surgery AND/OR Minimal Access Surgery AND/OR Robotics AND/OR Robotic Surgery AND/OR Endoscopic Surgery AND/OR Virtual Reality AND/OR Simulation OR Surgical Training/Education. RESULTS: The results were assessed according to level of evidence as reflected by the Oxford Centre of Evidence-based Medicine Levels of Evidence. CONCLUSIONS: In the current literature, no firm consensus exists on the importance of haptic feedback in performing minimally invasive surgery. Although the majority of the results show positive assessment of the benefits of force feedback, results are ambivalent and not unanimous on the subject. Benefits are least disputed when related to surgery using robotics, because there is no haptic feedback in currently used robotics. The addition of haptics is believed to reduce surgical errors resulting from a lack of it, especially in knot tying. Little research has been performed in the area of robot-assisted endoscopic surgical training, but results seem promising. Concerning VR training, results indicate that haptic feedback is important during the early phase of psychomotor skill acquisition.

Improved competence after a palliative care course for internal medicine residents.

Residents report that they received inadequate teaching in palliative care and low levels of comfort and skills when taking care of dying patients. This study describes the effects of a problem-based palliative care course on perceived competence and knowledge in a representative Dutch cohort of residents in internal medicine. Before and after the course, we carried out a questionnaire survey and knowledge test in 91 residents. The results show that many residents felt they had limited competence or were incompetent when taking care of patients in the palliative care phase. This was particularly true with respect to communication concerning euthanasia and physician-assisted suicide or hastened death (86% and 85% respectively reported limited competence or incompetence). Participants reported that they received inadequate training in palliative care and believed that specific education would make them feel more competent. The number of times that residents were engaged in palliative care situations and the years of clinical experience had a positive influence on perceived competence. Participating in the course improved perceived competence and knowledge in palliative care. No correlation was found between perceived competence and knowledge of palliative care.

Serious gaming and voluntary laparoscopic skills training: a multicenter study.

This study assesses the issue of voluntary training of a standardized online competition (serious gaming) between surgical residents. Surgical residents were invited to join a competition on a virtual reality (VR) simulator for laparoscopic motor skills. A final score was calculated based on the task performance of three exercises and was presented to all the participants through an online database on the Internet. The resident with the best score would win a lap-top computer. During three months, 31 individuals from seven hospitals participated (22 surgical residents, 3 surgeons and six interns). A total of 777 scores were logged in the database. In order to out-perform others some participants scheduled themselves voluntarily for additional training. More attempts correlated with higher scores. The serious gaming concept may enhance voluntary skills training. Online data capturing could facilitate monitoring of skills progression in surgical trainees and enhance (VR) simulator validation.
