Interval assessment using task- and procedure-based simulations: an attempt to supplement neurosurgical residency curriculum.

OBJECTIVE: The longer learning curve and smaller margin of error make nontraditional, or "out of operating room" simulation training, essential in neurosurgery. In this study, the authors propose an evaluation system for residents combining both task-based and procedure-based exercises and also present the perception of residents regarding its utility. METHODS: Residents were evaluated using a combination of task-based and virtual reality (VR)-based exercises. The results were analyzed in terms of the seniority of the residents as well as their laboratory credits. Questionnaire-based feedback was sought from the residents regarding the utility of this evaluation system incorporating the VR-based exercises. RESULTS: A total of 35 residents were included in this study and were divided into 3 groups according to seniority. There were 11 residents in groups 1 and 3 and 13 residents in group 2. On the overall assessment of microsuturing skills including both 4-0 and 10-0 microsuturing, the suturing skills of groups 2 and 3 were observed to be better than those of group 1 (p = 0.0014). Additionally, it was found that microsuturing scores improved significantly with the increasing laboratory credits (R2 = 0.72, p < 0.001), and this was found to be the most significant for group 1 residents (R2 = 0.85, p < 0.001). Group 3 residents performed significantly better than the other two groups in both straight (p = 0.02) and diagonal (p = 0.042) ring transfer tasks, but there was no significant difference between group 1 and group 2 residents (p = 0.35). Endoscopic evaluation points were also found to be positively correlated with previous laboratory training (p = 0.002); however, for the individual seniority groups, the correlation failed to reach statistical significance. The 3 seniority groups performed similarly in the cranial and spinal VR modules. Group 3 residents showed significant disagreement with the utility of the VR platform for improving surgical dexterity (p = 0.027) and improving the understanding of surgical procedures (p = 0.034). Similarly, there was greater disagreement for VR-based evaluation to identify target areas of improvement among the senior residents (groups 2 and 3), but it did not reach statistical significance (p = 0.194). CONCLUSIONS: The combination of task- and procedure-based assessment of trainees using physical and VR simulation models can supplement the existing neurosurgery curriculum. The currently available VR-based simulations are useful in the early years of training, but they need significant improvement to offer beneficial learning opportunities to senior trainees.

Challenges and prospects of neurosurgical teleconsultations in a developing country: a reality check.

OBJECTIVE: The adoption of telemedicine became a necessity during the COVID-19 pandemic because patients found commuting to be difficult owing to travel restrictions. Initially, audio-based teleconsultations were provided. Later, on the basis of the feedback of patients and caregivers, the authors started to provide video-based teleconsultations via WhatsApp. The authors subsequently surveyed the patients and caregivers to determine their satisfaction levels with telemedicine services. METHODS: An anonymized telephone survey of patients who had participated in teleconsultation was conducted with a structured questionnaire. The responses were analyzed and their correlations with the perceived benefits and limitations of audio and video teleconsultation were determined. RESULTS: Three hundred respondents were included in the first round of surveys, of whom 250 (83.3%) consented to video teleconsultation. Among the respondents who participated in both audio and video teleconsultations (n = 250), paired analysis showed that video teleconsultation was perceived as better in terms of providing easier access to healthcare services (p < 0.001), saving time (p < 0.001), and satisfaction with the way patient needs were conveyed to healthcare providers (p = 0.023), as well as in terms of adequacy of addressing healthcare needs (p < 0.001) and consequently providing a higher rate of overall satisfaction (p < 0.001). For both audio and video teleconsultation, overall patient satisfaction was significantly related to only previous exposure to WhatsApp. However, for video consultation, longer call duration (p = 0.023) was an important independent factor. Video teleconsultation was preferable to face-to-face consultation irrespective of educational status, but higher education was associated with preference for video teleconsultation. CONCLUSIONS: Both audio and video teleconsultation are viable cost-effective surrogates for in-person physical neurosurgical consultation. Although audio teleconsultation is more user-friendly and is not restricted by educational status, video teleconsultation trumps the former owing to a more efficient and satisfactory doctor-to-patient interface.

Managing Traumatic Brain Injury During the Coronavirus Disease 2019 Pandemic-A Case-Matched Controlled Analysis of Immediate Outcomes.

OBJECTIVE: The primary objective of this study was to evaluate the outcome of patients with traumatic brain injury (TBI) during the coronavirus disease 2019 (COVID-19) pandemic and to compare their outcome with case-matched controls from the prepandemic phase. METHODS: This is a retrospective case-control study in which all patients with TBI admitted during COVID-19 pandemic phase (Arm A) from March 24, 2020 to November 30, 2020 were matched with age and Glasgow Coma Scale score-matched controls from the patients admitted before March 2020 (Arm B). RESULTS: The total number of patients matched in each arm was 118. The length of hospital stay (8 days vs. 5 days; P < 0.001), transit time from emergency room to operation room (150 minutes vs. 97 minutes; P = 0.271), anesthesia induction time (75 minutes vs. 45 minutes; P = 0.002), and operative duration (275 minutes vs. 180 minutes; P = 0.002) were longer in arm A. Although the incidence of fever and pneumonia was significantly higher in arm A than in arm B (50% vs. 26.3%, P < 0.001 and 27.1% vs. 1.7%, P < 0.001, respectively), outcome (Glasgow Outcome Scale-Extended) and mortality (18.6% vs. 14.4% respectively; P = 0.42) were similar in both the groups. CONCLUSIONS: The outcome of the patients managed for TBI during the COVID-19 pandemic was similar to matched patients with TBI managed at our center before the onset of the COVID-19 pandemic. This finding suggests that the guidelines followed during the COVID-19 pandemic were effective in dealing with patients with TBI. This model can serve as a guide for any future pandemic waves for effective management of patients with TBI without compromising their outcome.

Hybrid Workshops During the COVID-19 Pandemic-Dawn of a New Era in Neurosurgical Learning Platforms.

BACKGROUND: During the COVID-19 pandemic, disruption of surgical hands-on training has hampered the skills acquisition by budding neurosurgeons. Online and virtual classrooms have not been able to substitute the hands-on experience and learning via direct interaction with senior colleagues. To overcome these challenges, we organized a hybrid workshop where simulation-based learning modules, and direct and virtual interaction with surgeons during live surgeries or didactic lectures were utilized to help delegates in understanding the nuances of neurosurgery. METHODS: A 3-day hybrid workshop was held in March 2021, which was attended by 133 delegates. A structured questionnaire was utilized to record their feedback. RESULTS: An overwhelming majority of the respondents (94.1%, n = 64) found hybrid conferences to be better than an online conference. Most of the respondents (88.3%, n = 60) rated the utility of direct face-to-face interaction to be more satisfying as compared with online interaction with faculty during a webinar. Again, many the respondents (86.8%, n = 59) believed that similar hybrid events will be the new normal given the current situation of COVID-19 pandemic. A large majority (88.2%, n = 60) of the respondents reported that they will prefer a hybrid event over an online conference. CONCLUSIONS: In this era of the COVID-19 pandemic, "hybrid" microneurosurgery workshops offer unique opportunities to enhance surgical skills acquisition by hands-on simulation-based learning and observing live surgical demonstrations, apart from 2-way interactions with experts under one roof. This may be a stepping stone for what lies ahead in the future of neurosurgical training.

Role of virtual modules to supplement neurosurgery education during COVID-19.

The advent of the COVID-19 pandemic has disrupted all aspects of neurosurgery education, and it is now challenging to conduct routine sessions. Maintenance of essential standard education among novice neurosurgeons during the pandemic is of paramount importance. The aim of this study was the development of virtual modules and validation of its role to supplement the neurosurgery education program. We developed the virtual modules relevant to neuro-anatomy, neurosurgical procedures, instrumentation, and neurosurgical planning. These modules were virtually demonstrated to twenty-seven resident neurosurgeons through CiscoWebexonline platform. They provided their rating on the aptness of virtual modules for different neurosurgery applications on various parameters using 10 points Likert scale. The parameters included quality, learning, confidence building capacity, usefulness, and overall satisfaction. The results obtained for each module were analysed and the average score was used for the comparison. The highest rating on quality was obtained by the neurosurgical instrumentation module. The highest rating for learning and confidence building capacity was given to neurosurgical procedure animation. The usefulness and overall satisfaction were highly rated for neurosurgical planning module. The results show that developed virtual modules provide an effective method to supplement the neurosurgery education program in the current scenario involving physical distancing and shift rearrangements. These virtual modules help in limiting the visits to operation room, anatomy and surgical training labs, and allow residents to learn online at their pace.

Analysis of Neurosurgical Cases Before and During the Coronavirus Disease 2019 Pandemic from a Tertiary-Care Centre in India.

OBJECTIVE: We present the unique administrative issues as well as specific patient-related and surgeon-related challenges and solutions implemented while treating neurosurgical patients during the coronavirus disease 2019 (COVID-19) pandemic vis-à-vis pre-COVID-19 times at our tertiary-care center. METHODS: This is a retrospective study comparing the outcome of the neurosurgical patients treated from the beginning of lockdown in India on March 25, 2020 to November 30, 2020 with that of same period in the previous year, 2019. RESULTS: There were 687 neurosurgery admissions during the study period compared with 2550 admissions in 2019. The total number of surgeries performed in neurosurgery also showed a similar trend, with only 654 surgeries in 2020 compared with 3165 surgeries in 2019. During COVID-19 times, 474 patients were operated on including both trauma and nontrauma cases. Of the 50 patients with suspected/indeterminate COVID-19 who were operated on, 5 turned out to be positive for COVID-19. Significant differences were seen in the mortality (P < 0.01) and morbidity (P < 0.01) among patients with trauma on comparing COVID and pre-COVID periods. Similarly, a significant difference was observed in the mortality (P < 0.001) and morbidity (P < 0.001) in patients who did not have trauma. CONCLUSIONS: The higher mortality and morbidity during the COVID pandemic is primarily attributable to poorer baseline clinical status. Our experience from this COVID period might not only help us in tackling subsequent waves but also help other institutions in the developing world to be better prepared for similar circumstances.

Turning a New Chapter in Neurosurgery Outpatient Services: Telemedicine A "Savior" in this Pandemic.

BACKGROUND: Teleconsultation services in India, especially in neurosurgery, are relatively new. Despite its large-scale adoption during the COVID-19 pandemic, comprehensive analyses of patients' perspectives and hurdles are lacking. MATERIALS AND METHODS: We conducted an anonymized telephonic survey of consecutive neurosurgical patients who availed telemedicine services at our institute, using a validated, structured questionnaire. To prevent bias, interviewers were not involved in the study design/analyses. Patients' perception of usefulness and performance of teleconsultation was graded on a 5-point Likert scale. RESULTS: Of the 330 patients who availed teleconsultation services, 231 (70%) completed the survey. Even though 91% of the respondents had access to a smartphone, only 10% received a video-based teleconsult. As per respondents, the challenges included poor network (7%), suboptimal communication/discussion (5.6%), lack of physical examination (6%), and misinterpretation of prescription by pharmacists/patients (6%). The majority of the respondents (58%) either agreed/strongly agreed that teleconsultation helped them tide over the medical exigency during the lockdown; however, the clinical diagnosis did not influence this response (P = 0.21). The vast majority of the respondents felt that teleconsultation is beneficial (97%), as it minimizes their exposure to COVID-19. One-third of the patients preferred this service over physical visits and 60% agreed to its continuation till resumption of routine care. Access to video-teleconsultation was the chief suggestion in 39 of 74 suggestions received. CONCLUSIONS: Telemedicine in neurosurgery offers favorable patient satisfaction during this pandemic and may be a satisfactory alternative to physical outpatient services in the future. Video-based teleconsults should be the preferred modality of communication for neurosurgery patients.

Trends in Neurosurgical Teleconsultation Services Across the Globe During COVID-19 Pandemic.

BACKGROUND: Global use of telemedicine has increased rapidly during the coronavirus disease 2019 (COVID-19) pandemic to bridge the gap in existing health care services. Intercontinental trends in neurosurgeons' perception and practices of telemedicine have been sparingly reported. METHODS: We conducted an online anonymized and validated survey using a structured questionnaire to gain insight into neurosurgeons' experience with telemedicine across various continents and rated its usefulness on a 5-point Likert scale. RESULTS: We received 286 responses across 5 continents. There was a trend to support a major paradigm shift favoring teleconsultations during the COVID-19 pandemic in respondents from North America (P = 0.06). Signed prescriptions were e-mailed along with video-based teleconsultations preferentially in Europe and North America. In comparison, audio- or text-based teleconsultations along with unsigned prescriptions were prevalent in Asia and Africa (P = 0.0005). Acceptability and perceived usefulness for telemedicine during the pandemic were similar across the globe, regardless of neurosurgeons' experience (mean satisfaction score 3.72 ± 1.09; P = 0.62). A majority of neurosurgeons from Asia and South America complained of difficulties during teleconsultations owing to lack of appropriate infrastructure, internet connectivity/prescription-related issues, and potential risk of litigation (P = 0.0005). Approximately 46% of neurosurgeons, predominantly from Europe and North America, thought that telemedicine could play a vital role in clinical practice even after the COVID-19 pandemic subsides (mean satisfaction score 3.26 ± 1.16; P = 0.007). CONCLUSIONS: Telemedicine in neurosurgery is a viable alternative to physical outpatient services during the COVID-19 pandemic and could potentially play a vital role after the pandemic.

Preparedness and guidelines for neurosurgery in the COVID-19 era: Indian perspective from a tertiary care referral hospital.

The COVID-19 pandemic has severely impacted healthcare systems globally. The need of the hour is the development of effective strategies for protecting the lives of healthcare providers (HCPs) and judicious triage for optimal utilization of human and hospital resources. During this pandemic, neurosurgery, like other specialties, must transform, innovate, and adopt new guidelines and safety protocols for reducing the risk of cross-infection of HCPs without compromising patient care. In this article, the authors discuss the current neurosurgical practice guidelines at a high-volume tertiary care referral hospital in India and compare them with international guidelines and global consensus for neurosurgery practice in the COVID-19 era. Additionally, the authors highlight some of the modifications incorporated into their clinical practice, including those for stratification of neurosurgical cases, patient triaging based on COVID-19 testing, optimal manpower management, infrastructure reorganization, evolving modules for resident training, and innovations in operating guidelines. The authors recommend the use of their blueprint for stratification of neurosurgical cases, including their protocol for algorithmic patient triage and management and their template for manpower allocation to COVID-19 duty, as a replicable model for efficient healthcare delivery.

Guidelines for Preoperative Testing for Neurosurgery in Coronavirus Disease 2019 (COVID-19) Era: Indian Viewpoint Amidst Global Practice.

Preoperative testing and evaluation for coronavirus disease 2019 (COVID-19) have been an enigmatic challenge for the neurosurgical community during the pandemic. Since the beginning of the pandemic, laboratory diagnostic methods have evolved substantially, and with them has been the necessity for readily available, fast, and accurate preoperative testing methods. In this article, we provide an overview of the various laboratory testing methods that are presently available and a comprehensive literature review how various institutes and neurosurgical communities across the globe are employing them to ensure safe and effective delivery of surgical care to patients. Through this review, we highlight the guiding principles for preoperative testing, which may serve as a road map for other medical institutions to follow. In addition, we provide an Indian perspective of preoperative testing and share our experience in this regard.

In Memoriam: A Memoir for Our Fallen "Heroes".

Even though neurosurgeons exercise these enormous and versatile skills, the COVID-19 pandemic has shaken the fabrics of the global neurosurgical family, jeopardizing human lives, and forcing the entire world to be locked down. We stand on the shoulders of the giants and will not forget their examples and their teachings. We will work to the best of our ability to honor their memory. Professor Harvey Cushing said: "When to take great risks; when to withdraw in the face of unexpected difficulties; whether to force an attempted enucleation of a pathologically favorable tumor to its completion with the prospect of an operative fatality, or to abandon the procedure short of completeness with the certainty that after months or years even greater risks may have to be faced at a subsequent session-all these require surgical judgment which is a matter of long experience." It is up to us, therefore, to keep on the noble path that we have decided to undertake, to accumulate the surgical experience that these icons have shown us, the fruit of sacrifice and obstinacy. Our tribute goes to them; we will always remember their excellent work and their brilliant careers that will continue to enlighten all of us.

Video Section-Operative Nuances: Step by Step - Donning and Doffing in Neurosurgical Operating Room.

BACKGROUND AND INTRODUCTION: Donning and doffing of personal protective equipments (PPE) has become relevant especially during COVID-19 pandemic and neurosurgeons operating upon COVID-19 positive or suspect patients should be aware of proper technique of donning and doffing of PPE.[1] Surgeries involving direct exposure of anterior nasal spaces/paranasal sinuses carry significantly more risk of infection and it may be prudent to use PPE while operating all such cases.[2]. OBJECTIVE: In this video, we present our extensive protocol of donning and doffing of PPE which we have devised for our operating room. TECHNIQUE: Donning consists of wearing of the PPE in a proper sequence so as to afford maximal protection from viral infection while conducting the surgical procedure. Various components of PPE and procedure of donning is shown followed by doffing, the sequential and safe removal of the PPE. RESULTS: A meticulous method of donning and doffing PPE for neurosurgeons handling COVID-19 positive / suspect cases has been shown . CONCLUSION: Proper sequence of donning and doffing of PPE gear is of crucial importance during the COVID pandemic to prevent infection to the health care workers while handling COVID-19 positive/suspect cases and this video demonstrates the protocol we use at our institute.
