Beyond Traditional Training: Exploring the Benefits of Virtual Reality Simulator in Lumbar Pedicle Screw Insertion - A Randomized Controlled Trial.

INTRODUCTION: This study compares the effectiveness of Virtual Reality Simulators (VRS) and a saw bone model for learning lumbar pedicle screw insertion (LPSI) in neurosurgery. METHODOLOGY: A single-center, cross-sectional, randomized controlled laboratory investigation was conducted involving residents and fellows from a tertiary care referral hospital. Participants were divided into two groups (A and B). Group A performed three LPSI tasks: the first on a saw bone model, the second on VRS, and the third on another saw bone model. Group B completed two LPSI tasks, the first on a saw bone model and the second on another saw bone model. The accuracy of LPSI was evaluated through NCCT scans for the saw bone models, while the in-built application of VRS was utilized to check for accuracy of screw placement using the simulator. RESULTS: The study included 38 participants (19 in each group). Group A participants showed reduced mean entry point error (0.11 mm, p 0.024), increased mean purchase length (4.66 cm, p 0.007), and no cortical breaches (p 0.031) when placing the second saw bone model screw. Similar improvements were observed among group A participants in PGY 1-3 while placing the second saw bone model screws. CONCLUSIONS: VRS proves to be an invaluable tool for teaching complex neurosurgical skills, such as LPSI, to trainees. This technology investment can enhance the learning curve while maintaining patient safety.

Papillary Tumors of Pineal Region: A Single-Center Experience in Management of 11 Cases.

BACKGROUND: Papillary tumors of pineal region (PTPR) comprise a very rare subset of pineal region tumors that have been recently described. Literature on the management and outcome of PTPR is scarce owing to the rarity of these tumors. To address this lacuna, we analyzed our experience in management of PTPR. METHODS: We retrospectively analyzed the outcome of 11 patients with histopathologically proven PTPR who underwent surgical excision at our center. RESULTS: Mean patient age was 33.3 years (range, 12-45 years), and male-to-female ratio was 1.75:1. Headache was the most common presentation followed by visual disturbances, altered sensorium, Perinaud syndrome, and seizures. Cerebrospinal fluid diversion was required in 6 patients. Krause approach was the most common approach used for tumor excision (9/11 cases). There was no perioperative mortality. Two patients were lost to follow-up. In the remaining 9 patients, the average follow-up period was 45 months (range, 12-79 months). On first postoperative magnetic resonance imaging, 8 patients showed no evidence of residual tumor (gross total resection), while 1 patient had small residual tumor (near-total resection) that remained stable during follow-up. Four patients underwent adjuvant chemoradiotherapy. None of the patients developed recurrence during follow-up. CONCLUSIONS: PTPR are a rare subgroup of pineal region tumors with distinct cells of origin but presentation similar to other pineal region tumors. Surgical resection constitutes the mainstay of management, and the extent of resection appears to be the most important determinant of prognosis. The role of adjuvant therapy still needs to be determined.

Impact of penicillin allergy records on antimicrobial prescribing in hospitalised patients.

BACKGROUND: The overdiagnosis of penicillin allergy and misclassification of non-truly allergic reactions is a growing public health problem, associated with the overuse of broad-spectrum and restricted antimicrobials. We aimed to evaluate the impact of penicillin allergy status on antimicrobial prescribing. METHODS: A retrospective study of inpatients with a documented penicillin allergy receiving antimicrobials was conducted from 1 April to 1 July 2021. Antimicrobial prescribing and clinical characteristics were compared between patients with an active penicillin allergy label and those whose label was removed following antimicrobial stewardship team review. Antimicrobials were classified in two categories: i) 'Access' (recommended), ii) 'Watch and Reserve' (restricted) according to WHO AWaRe classification, a tool to guide appropriate antibiotic use. RESULTS: 437 patients with a documented penicillin allergy receiving antimicrobials were included. 353 patients with an active penicillin allergy label, more frequently received antimicrobials from the 'Watch and Reserve list' (283;80% vs 30;37%; p<0.001). In contrast, 84 patients who were de-labelled received more often antimicrobials from the 'Access list' (53;63% vs 64;18%; p<0.001). CONCLUSIONS: Penicillin allergy reviews and de-labelling strategies may reduce the use of restricted antimicrobials under the 'Watch and Reserve list'. This practice should be encouraged and reinforced in all hospitals.

Neurosurgery as a Top-Drawer Choice for Residency in India: Reality or Myth?

INTRODUCTION: This survey was conducted to explore the perceptions of undergraduate (UG) medical students regarding enrolling in a neurosurgical training program. The purpose was to understand' expectations, reasons, apprehensions, and variables influencing students' decisions to pursue a career in neurosurgery. The results shed light on students' perceptions and can help educational institutions and training programs draw in and encourage aspiring neurosurgeons. METHODS: A 35-point online questionnaire was created using Google Forms (Google LLC) after content and face validation and circulated using social media platforms among various public medical colleges across India. Responses were collected over a period of 3 months, from February 2023 to April 2023. A 5-point Likert scale was used to collect the responses wherever applicable. RESULTS: A total of 1042 respondents from 47 medical colleges completed the survey. The majority of the students were not exposed to neurosurgery during their UG program, but despite this, 60.1% (n = 627) were willing to consider it as their career option. Around 91.4% of the respondents perceived neurosurgery to be a challenging but prestigious specialty that has a long learning curve and the worst work-life balance when compared with other specialties. The majority of the respondents (strongly disagree = 24.3%, n = 253; disagree = 31.7%, n = 330) did not view neurosurgery as a male-dominated specialty. Most students preferred a 6-year training program over a 3-year program (P = 0.001) if their medical college had such a course. CONCLUSIONS: Our study reveals that although a majority of the UG students would like to join neurosurgery residency, there are significant barriers in the form of less exposure, negative perceptions, and apprehensions toward the branch. Enhancing medical students' awareness about neurosurgery necessitates the integration of hands-on workshops, simulation-based training, didactic lectures, and neurosurgery rotations into the UG curriculum.

Innovations in craniovertebral junction training: harnessing the power of mixed reality and head-mounted displays.

OBJECTIVE: The objective of this study was to analyze the potential and convenience of using mixed reality as a teaching tool for craniovertebral junction (CVJ) anomaly pathoanatomy. METHODS: CT and CT angiography images of 2 patients with CVJ anomalies were used to construct mixed reality models in the HoloMedicine application on the HoloLens 2 headset, resulting in four viewing stations. Twenty-two participants were randomly allocated into two groups, with each participant rotating through all stations for 90 seconds, each in a different order based on their group. At every station, objective questions evaluating the understanding of CVJ pathoanatomy were answered. At the end, subjective opinion on the user experience of mixed reality was provided using a 5-point Likert scale. The objective performance of the two viewing modes was compared, and a correlation between performance and participant experience was sought. Subjective feedback was compiled and correlated with experience. RESULTS: In both groups, there was a significant improvement in median (interquartile range [IQR]) objective performance with mixed reality compared with DICOM: 1) group A: case 1, median 6 (IQR 6-7) versus 5 (IQR 3-6), p = 0.009; case 2, median 6 (IQR 6-7) versus 5 (IQR 3-6), p = 0.02; 2) group B: case 1, median 6 (IQR 5-7) versus 4 (IQR 2-5), p = 0.04; case 2, median 6 (IQR 6-7) versus 5 (IQR 3-7), p = 0.03. There was significantly higher improvement in less experienced participants in both groups for both cases: 1) group A: case 1, r = -0.8665, p = 0.0005; case 2, r = -0.8002, p = 0.03; 2) group B: case 1, r = -0.6977, p = 0.01; case 2, r = -0.7417, p = 0.009. Subjectively, mixed reality was easy to use, with less disorientation due to the visible background, and it was believed to be a useful teaching tool. CONCLUSIONS: Mixed reality is an effective teaching tool for CVJ pathoanatomy, particularly for young neurosurgeons and trainees. The versatility of mixed reality and the intuitiveness of the user experience offer many potential applications, including training, intraoperative guidance, patient counseling, and individualized medicine; consequently, mixed reality has the potential to transform neurosurgery.

Specific sensory neurons and insulin-like peptides modulate food type-dependent oogenesis and fertilization in Caenorhabditis elegans.

An animal's responses to environmental cues are critical for its reproductive program. Thus, a mechanism that allows the animal to sense and adjust to its environment should make for a more efficient reproductive physiology. Here, we demonstrate that in Caenorhabditis elegans specific sensory neurons influence onset of oogenesis through insulin signaling in response to food-derived cues. The chemosensory neurons ASJ modulate oogenesis onset through the insulin-like peptide (ILP) INS-6. In contrast, other sensory neurons, the olfactory neurons AWA, regulate food type-dependent differences in C. elegans fertilization rates, but not onset of oogenesis. AWA modulates fertilization rates at least partly in parallel to insulin receptor signaling, since the insulin receptor DAF-2 regulates fertilization independently of food type, which requires ILPs other than INS-6. Together our findings suggest that optimal reproduction requires the integration of diverse food-derived inputs through multiple neuronal signals acting on the C. elegans germline.

An assessment of the variation in the practice of lumbar discectomy and its role in axial back pain.

Background: Lumbar discectomy is performed for symptomatic lumbar disc herniation and is one of the most widely performed spinal surgical procedures worldwide in a variety of ways. This survey aimed at providing an overview/perspective of different practice patterns and the impact of lumbar discectomy on axial back pain with or without sciatica. Methods: An online survey was performed using the application "Google Forms." The link to the questionnaire was distributed to neurosurgeons through personal E-mail and social media platforms. Results: We received 333 responses. The largest percentage of responses across five continents was from Asia (66.97%, n = 223). The mean age of the respondents was 40.08 ± 10.5 years. A total of 66 respondents (20%) had a spine practice of 7%-90%, and 28 respondents had a spine practice of 90%-100% (8.4%). The number of respondents who practiced microscopic discectomy using a tubular retractor (n = 143 respondents, 42.9%) was nearly equal to the number of respondents who practiced open discectomy (n = 142 respondents, 42.6%). An almost equal proportion of respondents believed discectomy does not help in relieving axial back pain. Only 20.4% (n = 68) of respondents recommend bed rest for a longer duration postoperatively. Conclusions: Our survey revealed that only 22.2% of spine surgeons recommended discectomy in patients with radiological disc herniation with axial back pain alone and preferred a minimally invasive method of discectomy. Almost half of them believed discectomy to be ineffective for axial low back pain and only a few recommended prolonged bed rest postoperatively.

Impact of green finance and fintech on sustainable economic growth: Empirical evidence from India.

This research study analytically investigates the influence of green finance and financial technology on sustainable economic growth. The analysis is based on data from Indian states from 2010 to 2021. The research paper uses the panel regression method to examine the association between fintech, green finance and economic growth by applying a two-step GMM (generalized model of moments) to determine the endogeneity issues of the variables. This paper reveals that green finance widely helps quality economic growth by significantly impacting finance structure, financial effectiveness, and environmental quality protection development. Furthermore, fintech enhances the significant effect of green finance in the finance structure and environmental quality protection while lacking consequences on the association between green finance and economic effectiveness. Based on the results, the current research paper offers policy submissions for policymakers and the Government of India, including strengthening the consolidation of fintech growth with green finance, structuring a quality environmental revelation outline to control state governments in refining the effectiveness of green finance, and emerging prolonged satisfactory protocol as an outside involvement proceeding to encourage green finance in the non-public sector.

Looking Beyond the Anterolateral Skull Base with Frontotemporal Dural Fold Unlocking and Extradural Clinoidectomy: A Series of 17 Cases Deciphering the Translation from a Cadaver to Real, and Real to Pathologically Distorted Anatomy.

Objective: This article aims to discuss the surgical nuances and major adjustments necessary in unlocking the frontotemporal dural fold (FTDF) and extradural anterior clinoidectomy (EDAC) in actual cases, allowing translation from the cadaveric to a clinical scenario. Materials and Methods: We retrospectively reviewed the technical details of 17 procedures over 8 years, where both the initial steps (FTDF unlocking and EDAC) were performed. Lesions involving or extending to the anterolateral skull base, like the suprasellar cistern, optico-carotid cistern, interpeduncular cistern, petrous apex, and cavernous sinus, were included. The clinical data of the patients were retrieved retrospectively from the hospital information system (HIS) and in-patient records. This study was approved as a multicenter individual project with IEC No: 2020-342-IP-EXP-34. Results: An illustrated note of the common steps and outcome of the 17 procedures of unlocking the FTDF and EDAC done is presented. The technique provided adequate exposure in performing aneurysmal clipping (posterior communicating artery [P. com], basilar top, and superior hypophyseal artery [SHA] aneurysm), giant pituitary adenoma (Wilson Hardy grade 4E, n = 2), fifth nerve schwannoma (n = 4), right Meckel's cave melanoma, cavernous hemangioma (n = 4), petroclival meningioma (n = 2), and clival chordoma. Temporary and permanent cranial nerve palsy as a procedure-related complication was seen in 11.8% (n = 2) each. Complete excision was achieved in 13 (n = 13/14) patients with tumors. Conclusion: FTDF unlocking and EDAC are elegant procedures providing reasonable access to the anterolateral skull base for myriad pathologies. Brain bulge, cavernous sinus bleeding, and losing the plane of dural duplication were significant challenges in switching from cadaveric to a clinical scenario.

SimSpine: A Cost-Effective Spinal Endoscopy Training Prototype for Neurosurgical Residents Skills Training.

OBJECTIVE: To compare the SimSpine (indigenously developed, low-cost model) and EasyGO! (Karl Storz, Tuttlingen, Germany) systems for simulation of endoscopic discectomy. METHODS: Twelve neurosurgery residents, 6 in postgraduate years 1-4 or equivalent (junior) and 6 in postgraduate years 5-6 or equivalent (senior), were randomly allocated (1:1) to either EasyGO! or SimSpine endoscopic visualization systems for endoscopic lumbar discectomy simulation on the same physical simulator. After the first exercise, the participants switched over to the other system, and the exercise was repeated. Time taken to dock the system, time to reach annulus, time required for task completion, dural violation, and volume of disc material removed were used for calculating objective efficiency score. Subjective scoring (Neurosurgery Education and Training School [NETS] criteria) was performed by 4 blinded mentors based on recorded video on 2 separate occasions 2 weeks apart. Cumulative score was calculated based on efficiency and Neurosurgery Education and Training School scores. RESULTS: Performance metrics were similar across the 2 platforms, regardless of participant seniority (P > 0.05). Time to reach disc space and discectomy time improved for both EasyGO! (P = 0.07 and P = 0.03, respectively) and SimSpine (P = 0.01 and P = 0.04, respectively) between first and second exercises. Efficiency and cumulative scores were better (P = 0.04 and P = 0.03 respectively) when EasyGO! was used as the first device compared with SimSpine. CONCLUSIONS: SimSpine is a cost-effective viable alternative to EasyGO for endoscopic lumbar discectomy simulation-based training.

Transcranial Surgery for Pituitary Tumors: A "Community Neurosurgery Experience".

Background: Despite the evolution of endoscopic techniques, large pituitary adenomas with unfavorable characteristics and irregular anatomical configurations continue to pose a challenge for the dexterity, skills, and patience of endoscopic surgeons. Transcranial surgery retains a significant role in these situations where the tumor access, hemostasis, and dissection around adjoining neurovascular tissues can be controlled efficaciously. Objective: In this report, we describe our experience with transcranial surgery for pituitary adenomas highlighting its safety and versatility in peripheral centers. Methods: We accessed the case files and imaging records of pituitary tumors operated between 2001 and 2019 at a private hospital in a major Indian city. The records were analyzed with emphasis on postoperative clinical course, visual, and endocrinological outcomes. The data was analyzed with respect to differences between transcranial and transsphenoidal procedures. Categorical variables were compared with Chi-square test/Fischer's exact test and difference in means evaluated with Welch's t-test. Results: A total of 178 procedures were performed in 173 patients with pituitary adenoma, who were the subjects of this study. Ninety-eight (56.7%) patients were treated by transsphenoidal excision whereas 80 (46.2%) underwent transcranial procedures (75 primary and five secondary). In the patients operated transcranially, we observed three deaths and nine patients suffered from significant morbidity. Visual outcomes were similar to the group operated transsphenoidally. However, incidence of panhypopituitarism was significantly higher in transcranial procedures; the extent of resection was poorer than transsphenoidal surgeries owing to more extensive nature of tumors. Conclusions: In low-volume centers, the endoscopic skills required for transsphenoidal resection of large and complex pituitary adenomas may be scarce. Transcranial surgery, dependent on familiar microsurgical techniques and equipment, may still be viable, safe, and an effective option.

Effect of Age, Stage, and Type of Surgical Revascularization on Clinical and Angiographic Outcome in Moyamoya Disease - Experience from a Case Series of 175 Revascularization Procedures.

Background: There is dearth of literature on impact of age - pediatric versus adult, Suzuki staging - early versus late, and revascularization type - indirect versus direct on clinical and angiographic outcome in moyamoya disease (MMD). Hence, we intend to comprehensively evaluate factors influencing outcome in MMD following surgical revascularization. Methods: MMD patients operated at our institute from January 2011 to August 2018 were followed for an average 24 months. Primary outcomes were modified Rankin score (mRS) and stroke risk reduction. Secondary outcome was angiographic outcome score (AOS). Results: A total of 133 patients including 37.6% adults (>18 years; n = 50) underwent 175 revascularizations - 89 direct (DR) and 86 indirect (IR) subgroups. Mean mRS scores improved in pediatric DR (P < 0.001), IR (P < 0.001), adult IR (P = 0.10), and DR (P = 0.25) subgroups. Recurrent stroke rate was similar in pediatric-DR (2.7%) and IR (7.6%, P = 0.61), and adult-DR (0%) and IR (4.1%) subgroups (P = 1.00). AOS scores improved in pediatric DR (P = 0.002) and IR (P = 0.01), and adult-DR (P = 0.02) and IR (P = 0.06) subgroups. Late-stage MMD (Suzuki IV-VI) showed better improvement in mRS scores than early-stage-Suzuki (I-III; P < 0.001). Recurrent stroke rates were similar (P = 0.26) and AOS scores improved significantly in early- and late-stage MMD (P < 0.001). Conclusions: In pediatrics, clinical and angiographic outcome significantly improved after revascularization procedure, and in adults, angiographic improvement was more evident than clinical recovery. Late-stage Suzuki MMD patients demonstrated significantly better clinical improvement than early stage. The angiographic improvement was equivalent to early stage, irrespective of age and type of revascularization.

AIIMS Cervical Myelopathy Score - A New Comprehensive and Objective Patient-Reported Modification of mJOA: Results of an Internal Validation Study.

Background: Several scoring systems have been developed for assessment of patients with compressive cervical myelopathy. However, all of these have some shortcomings. We proposed a new modification of the modified Japanese Orthopedic Association (mJOA) score-the AIIMS cervical myelopathy score (ACMS). Objective: The aim of this study was to compare the ACMS with mJOA score and Nurick score. Methods: We prospectively studied patients with cervical compressive myelopathy. The new ACMS, mJOA, Nurick proposed by Benzel, and Nurick scores were recorded preoperatively and at three months postoperatively in patients. Results: Sixty-two patients completed the 3-month follow-up and were included in the final analysis. The mean preoperative and postoperative Nurick, mJOA, and ACMS scores were 3.3 and 3.0, 12.3 and 13.8, and 15.1 and 17.7, respectively. High correlation (Pearson's r > 0.8, 95% CI: 0.94 to 0.97, P < 0.005) was observed between ACMS and mJOA scores for all the individual components of both scales, both in pre- and postoperative assessments. A negative correlation was observed between the occupational ability scores ACMS and the Nurick scale (r = -0.76, 95% CI: -0.83 to - 0.68). No correlation was found with cord/canal ratio on magnetic resonance imaging (MRI) with any of the three scoring systems (preoperative, postoperative, or recovery rates). Conclusions: The ACMS score showed a good correlation with the mJOA score for evaluation of functional disability in the setting of cervical myelopathy. The patients could themselves report the scores using the ACMS scoring chart. The occupational component of the ACMS also correlated well with the Nurick score.

O-Arm Assisted Anterior Odontoid Screw Fixation in Type II and Rostral Type III Odontoid Fractures: Single Center Surgical Series of 50 Patients.

Background: Accuracy of screw placement is one of the important factors necessary for adequate union in odontoid fractures with malposition rates as high as 27.2% with standard techniques. Objective: To evaluate efficacy of intraoperative O-arm assistance in improving accuracy of anterior odontoid screw placement and clinco-radiological outcome in type II and III odontoid fractures. Material and Methods: In this retrospective study, surgery consisted of anterior odontoid screw fixation under intraoperative O-arm assistance over 5 years. Demographical, clinical, radiological, operative details and postoperative events were retrieved from hospital database and evaluated for fusion and surgical outcome. Results: 50 patients (Mean age 34.6 years, SD 14.10, range: 7-70 years; 44 males and 6 females) with Type II and Type III odontoid fracture underwent O-arm assisted anterior screw placement. The mean interval between injury and surgery was 12 days (range 1-65 days). Mean operating time was 132.2 min ± SD 33.56 with average blood loss of 93 ml. ±SD 61.46. With our technique, accurate screw placement was achieved in 100% patients. At the mean follow-up of 26.4 month (SD13.75), overall acceptable fusion rate was 97.8% with non-union in 2.2% patients. Morbidity occurred in two patients; one patient developed fixation failure while other patient had nonunion which was managed with posterior C1-C2 arthrodesis. We had surgical mortality in one patient due to SAH. So overall our procedure was successful in 94% patients and among patients whose follow-up was available, acceptable fusion rates of 97.8% were achieved. Conclusion: We conclude that use of intraoperative three-dimensional imaging using O-arm for anterior odontoid screw fixation improves accuracy and leads to improved radiological and clinical outcomes. It further enables us to extend the indications of odontoid screw fixation to selected complex Type II and rostral Type III odontoid fractures.

Use of Assessment Tools in Cervical Spondylotic Myelopathy-Results of An Anonymized Survey Among Indian Spine Surgeons.

Background: Cervical spondylotic myelopathy (CSM) is the commonest cause of cervical myelopathy. It contributes to high morbidity and consequent economic burden for society. Many measurement tools have been devised to quantify the disease severity, assist in decision-making, and to evaluate the outcome of surgical intervention. Objective: Most of the assessment scales are used for research purposes only and rarely in clinical practice. The purpose of this survey was to check the awareness of spine surgeons about these assessment scales and their role in the management of patients with CSM. Methods: An online questionnaire using the application "Google Forms" made consisting of 10 questions regarding the experience of treating the CSM patients and their preference for various parameters in assessing these patients. Statistical analysis was done using the statistical programming language R. Results: One-hundred and sixty-three responses were analyzed. About 90% of the respondents were aware of the assessment tools and only 57% of them used any in management. Nurick's grade was the most well known among all groups. The commonest reason for surgeons not using any of these assessment scales despite being aware of these scales was their perception that it is very time-consuming to complete these assessment scales. Conclusion: Assessment scales have a role in the management and follow-up of CSM patients. While awareness regarding these tools is well spread, time constraint plays a major role in limiting its usage.

Cervical Spine Fracture with Extreme Dislocation in a Patient with Ankylosing Spondylitis: A Case Report and Systematic Review of the Literature.

Background: Ankylosing spondylitis (AS) is a seronegative arthropathy which results in pathological ossification of the ligaments, disc, endplates and apophyseal structures. Cervical spinal fractures are more common in patients with ankylosing spondylitis than in patients without ankylosing spondylitis due to coexistent osteoporosis and kyphotic alignment of the spine. The risk of fracture-dislocation and associated spinal cord injury is also more in these patients. Management of cervical spine fractures in patients with ankylosing spondylitis is more challenging. Case Description: We report a 56-year-old male patient who presented to our emergency department following a road traffic accident. He had ASIA B spinal cord injury at C7 level. CT scan revealed a C6-7 fracture-dislocation with features suggestive of AS. The fracture involved all the three columns and extended through C7 body anteriorly and through the C6-7 disc posteriorly. The treating team was not aware that he had AS, and thus, precautions related to his head position were not taken. He underwent reduction of the fracture-dislocation and 360° fixation. Conclusions: The management of cervical spine fractures in patients with ankylosing spondylitis is challenging. They need long segment fixation in their preoperative spinal alignment. Proper preoperative planning can result in good outcome.

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.
