Objectives: The relationship between the volume of medical procedures conducted in hospitals and the resulting health outcomes has been described for various surgical and non-surgical medical interventions. As a policy response to this, several countries have implemented minimum volume standards. However, there is currently a lack of systematically compiled evidence assessing their impact. To close this research gap, we conducted a systematic review on the effects of minimum volume standards in hospitals. Design: Systematic review using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Data sources: MEDLINE, PubMed Central and Bookshelf (PubMed), EMBASE (Elsevier), CENTRAL (Cochrane Library), CINHAL (EBSCO), EconLIT (EBSCO), PDQ-Evidence for Informed Health Policymaking, Health Systems Evidence and three trial registries were searched until June 2023. Additionally, manual searches were conducted. Eligibility criteria for selecting studies: For inclusion in this review, studies must investigate the effects of minimum volume standards. We accepted all categories of outcomes. Following the Cochrane Effective Practice and Organisation of Care (EPOC) criteria, only a strict set of study designs, namely randomised controlled trials, non-randomised controlled trials, controlled before-after studies and interrupted time series studies, were included. No restrictions were placed on language, publication date or publication status. Data extraction and synthesis: Two reviewers independently screened titles and abstracts for eligibility, reviewed the full texts and performed data extraction of the included articles. Risk of bias was assessed using the 'Risk Of Bias In Non-Randomised Studies-of Interventions' (ROBINS-I) tool. Certainty of evidence was rated using the GRADE approach. For data synthesis and statistical analyses, we adhered to the EPOC guidance. Results: We included nine studies into our systematic review. Overall, the outcomes reported in the studies are heterogeneous, which did not allow for a meta-analysis, resulting in a narrative analysis of the found evidence. While travel distance increased and length of stay decreased, other reported outcomes such as complications or reoperations were not affected by the introduction of minimum volume standards. Overall, the risk of bias was considered serious for results on outcomes of seven out of the nine included studies and moderate for the remaining two. The certainty of evidence was rated low for complications, reoperations, length of stay and travel distance and very low for mortality (in-hospital; 30 days). Conclusion: This systematic review does not provide conclusive evidence on the effects of minimum volume standards in hospitals regarding any outcomes. The certainty of evidence for mortality (in-hospital; 30 days) is very low and low for complications, reoperations and travel distance. The results are based on a relatively small number of studies for most outcomes. There is a need for studies researching the effects of minimum volume standards based on a robust study design.

Postoperative gastrointestinal disorder (POGD) was a common complication after surgery under anesthesia. Strategies in combination with Traditional Chinese Medicine and Western medicine showed some distinct effects but standardized clinical practice guidelines were not available. Thus, a multidisciplinary expert team from various professional bodies including the Perioperative and Anesthesia Professional Committees of the Chinese Association of Integrative Medicine (CAIM), jointly with Gansu Province Clinical Research Center of Integrative Anesthesiology/Anesthesia and Pain Medical Center of Gansu Provincial Hospital of Traditional Chinese Medicine and WHO Collaborating Center for Guideline Implementation and Knowledge Translation/Chinese Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Center/Gansu Provincial Center for Medical Guideline Industry Technology/Evidence-based Medicine Center of Lanzhou University, was established to develop evidence-based guidelines. Clinical questions (7 background and 12 clinical questions) were identified through literature reviews and expert consensus meetings. Based on systematic reviews/meta-analyses, evidence quality was analyzed and the advantages and disadvantages of interventional measures were weighed with input from patients' preferences. Finally, 20 recommendations were developed through the Delphi-based consensus meetings. These recommendations included disease definitions, etiologies, pathogenesis, syndrome differentiation, diagnosis, and perioperative prevention and treatment.

Authors' objectives: Glaucoma is the term for a group of eye disorders that causes progressive damage to the optic nerve, which can lead to visual impairment and, potentially, irreversible blindness. Minimally invasive bleb surgery (MIBS) reduces eye pressure through the implantation of a device that creates a new subconjunctival outflow pathway for eye fluid drainage. MIBS is a less invasive alternative to conventional/incisional glaucoma surgery (e.g., trabeculectomy). We conducted a health technology assessment of MIBS for people with glaucoma, which included an evaluation of effectiveness, safety, the budget impact of publicly funding MIBS, and patient preferences and values.

Background: Children born in Sub-Saharan Africa (SSA) have an 85 % risk of requiring surgical care by the age of 15 [1,2]. Yet, children's surgery has been largely neglected by global health policies. National Surgical Obstetric and Anaesthetic Plans' (NSOAPs) reflect countries' strategic health priorities, policies, and targets related to surgical care. This study assessed the prioritisation of children's surgical care in national surgical care policies in SSA. Methods: This systematic review of national surgical care policies in SSA conducted in December 2022, analysed NSOAPs developed in SSA electronically for search terms "child∗", "pediatric∗", "paediatric∗" and evaluated manually for children's surgical care in relation to the NSOAP domains, health system building blocks, and surgical care. Policies were evaluated for collaboration. Results: Eight policies met the inclusion criteria. In the 797 (M = 99.63; SD = 34.83) text-containing pages analysed, there were 258 (15.5; 0-164) mentions of children's surgery search terms. Twenty-five percent (n = 2) of the NSOAPs dedicated sections to children's surgical care, 62.5 % (n = 5) mentioned children's surgery, and 12.5 % (n = 1) did not mention children's surgery. Children's surgery received citations in 25 % (n = 2) of backgrounds, 37.5 % (n = 3) of situational analyses, 87.5 % (n = 7) of strategic frameworks, 37.5 % (n = 3) of monitoring and evaluation, and 25 % (n = 2) of the costing sections. Overall, 62.5 % (n = 5) of countries included a children's surgery stakeholder. Conclusion: NSOAPs are a pragmatic measure of national surgical care priorities. Our findings suggest children's surgery is not widely recognised even where commitments to improving surgical care exist. Greater prioritisation of children's surgery is needed in surgical policy development.

This study aims to conduct a systematic review of full economic analyses of robotic-assisted surgery (RAS) in adults' thoracic and abdominopelvic indications. Authors used Medline, EMBASE, and PubMed to conduct a systematic review following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) 2020 guidelines. Fully published economic articles in English were included. Methodology and reporting quality were assessed using standardized tools. Majority of studies (28/33) were on oncology procedures. Radical prostatectomy was the most reported procedure (16/33). Twenty-eight studies used quality-adjusted life years, and five used complication rates as outcomes. Nine used primary and 24 studies used secondary data. All studies used modeling. In 81% of studies (27/33), RAS was cost-effective or potentially cost-effective compared to comparator procedures, including radical prostatectomy, nephrectomy, and cystectomy. Societal perspective, longer-term time-horizon, and larger volumes favored RAS. Cost-drivers were length of stay and equipment cost. From societal and payer perspectives, robotic-assisted surgery is a cost-effective strategy for thoracic and abdominopelvic procedures.Clinical trial registration This study is a systematic review with no intervention, not a clinical trial.

Study Objective:The role of transversus thoracic muscle plane blocks (TTMPBs) during cardiac surgery is controversial. We conducted a systematic review to establish the effectiveness of this procedure. Design:Systematic review. We searched PubMed, Embase, Web of Science, CENTRAL, WanFang Data, and the China National Knowledge Infrastructure to June 2022, and followed the GRADE approach to evaluate the certainty of evidence. Study Eligibility Criteria:Eligible studies enrolled adult patients scheduled to undergo cardiac surgery and randomized them to receive a TTMPB or no block/sham block. Main Results:Nine trials that enrolled 454 participants were included. Compared to no block/sham block, moderate certainty evidence found that TTMPB probably reduces postoperative pain at rest at 12 h [weighted mean difference (WMD) -1.51 cm on a 10 cm visual analogue scale for pain, 95% CI -2.02 to -1.00; risk difference (RD) for achieving mild pain or less (& LE;3 cm), 41%, 95% CI 17-65) and 24 h (WMD -1.07 cm, 95% CI -1.83 to -0.32; RD 26%, 95% CI 9-37). Moderate certainty evidence also supported that TTMPB probably reduces pain during movement at 12 h (WMD -3.42 cm, 95% CI -4.47 to -2.37; RD 46%, 95% CI 12-80) and at 24 h (WMD -1.73 cm, 95% CI -3.24 to -0.21; RD 32%, 95% CI 5-59), intraoperative opioid use [WMD -28 milligram morphine equivalent (MME), 95% CI -42 to -15], postoperative opioid consumption (WMD -17 MME, 95% CI -29 to -5), postoperative nausea and vomiting (absolute risk difference 255 less per 1000 persons, 95% CI 140-314), and intensive care unit (ICU) length of stay (WMD -13 h, 95% CI -21 to -6). Conclusion:Moderate certainty evidence showed TTMPB during cardiac surgery probably reduces postoperative pain at rest and with movement, opioid consumption, ICU length of stay, and the incidence of nausea and vomiting.

BACKGROUND: Pediatric endoscopic skull base surgery is challenging due to the intricate anatomy of the skull base and the presence of tumors with varied pathologies. The use of three-dimensional (3D) printing technologies in skull base surgeries has been found to be highly beneficial. A systematic review of the literature was performed to investigate the published studies that reported the effectiveness of 3D printing in pediatric endoscopic skull base surgery. METHODS: Pub Med, Embase, Science Direct, The Cochrane Library, and Scopus were searched from January 01, 2000, until June 30, 2022. Original articles of any design reporting on the effectiveness of 3D printing in pediatric endoscopic skull base surgery were included. Information related to study population, conditions, models used, and key findings of study were extracted. Quality of included studies was evaluated using the Joanna Briggs Institute's (JBI) Critical Appraisal Checklist for Studies. To exemplify the use of 3D technology in this scenario, we report a complex clival chordoma case. RESULTS: Six research articles were retrieved and included for qualitative analysis. Four of the six studies were conducted in the United States, followed by two in China. According to these studies, 3D reconstruction and printed models were more beneficial than CT/MRI images when discussing surgery with patients. In clinical training, these models were more helpful than 2D images in understanding the pathology when used in conjunction with image-guiding systems. It has been found that patient-specific 3D modeling, simulations, and rehearsal are the most efficient preoperative planning techniques, particularly in the pediatric population, for the treatment of complicated skull base surgeries. All the studies had a moderate risk of bias. CONCLUSION: 3D printing technologies assist in printing complex skull base tumors and the structures around them in three dimensions at the point of care and at the time needed, enabling the choice of the appropriate surgical strategy, thus minimizing surgery-related complications.

Robotic-assisted colorectal surgery (RACS) is steadily increasing in popularity with an annual growth in the number of colorectal procedures undertaken robotically. Further upscaling of RACS requires structured and standardised robotic training to safeguard high-quality clinical outcomes. The aims of this systematic review were to assess the structure and assessment metrics of currently established RACS training programmes. A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines was performed. Searches were performed of the Ovid Medline, Embase and Web of Science databases between 2000 and 27th November 2021 to identify studies reporting on training curricula in RACS. Core components of training programmes and their relevant outcome assessment metrics were extracted. Thirteen studies were identified, with all training programmes designed for the da Vinci platform (Intuitive Surgical, Inc., Sunnyvale, CA, USA). Common elements of multimodal programmes included theoretical knowledge (76.9%), case observation (53.8%), simulation (100%) and proctored training (76.9%). Robotic skills acquisition was assessed primarily during the simulation phase (30.1%) and proctoring phase (76.9%). Performance metrics, consisting of time or assessment scores for VR simulation were only mandated in four (30.1%) studies. Objective assessment following proctored training was variably reported and employed a range of assessment metrics, including direct feedback or video feedback. Five (38.4%) training programmes used the Global Assessment Score (GAS) forms. There is a broad consensus on the core multimodal components across current RACS training programmes; however, validated objective assessment is limited and needs to be appropriately standardised to ensure reproducible progression criteria and competency-based metrics are produced to robustly assess progression and competence.

OBJECTIVE: Enhanced recovery after surgery (ERAS) protocols aim to optimize the pre-, intra-, and postoperative care of patients to improve surgery outcomes, reduce complications, decrease length of stay, and more. We aim to perform a systematic review and meta-analysis of ERAS protocols for head and neck cancer surgery with or without microvascular reconstruction. DATA SOURCES: PubMed, Embase, and Web of Science databases were queried, and abstracts were screened independently by 2 investigators. REVIEW METHODS: This review was conducted in accordance with the PRISMA guidelines. We included comparative observational studies but excluded animal studies, case reports, and case series. RESULTS: Of 557 articles initially reviewed by title and/or abstract, we identified 30 for full-text screening, and 9 met the criteria for qualitative synthesis. Meta-analysis of length of stay revealed a mean decrease of 1.37 days (95% CI, 0.77-1.96; I(2) = 0%; P < .00001) with the ERAS group as compared with non-ERAS controls. The standardized mean difference of the morphine milligram equivalent was 0.72 lower (95% CI, 0.26-1.18; I(2) = 82%; P = .002) in the ERAS group vs controls. The quality of studies was moderate with a median MINORS score of 18.5 (range, 13.5-21.5). CONCLUSION: Implementation of ERAS protocols can lead to decreases in length of stay and opioid drug utilization. However, further high-quality prospective studies of ERAS protocols are needed, especially with stratified analysis of outcomes based on the type of head and neck cancer surgery.

INTRODUCTION: In orthopaedic surgery, hip fracture patients represent one of the largest cohorts. Hip fracture is a serious injury commonly occurring in frail and elderly patients. Fast-track admission pathways aim to streamline patients through accident and emergency departments, resulting in shorter wait times and less negative patient outcomes. Aim To examine the impact of a fast-track pathway on length of stay for adults admitted to an acute hospital with a hip fracture. METHODS: CINAHL Plus with Full text (via EBSCO host), MEDLINE, Cochrane Library, and Embase database searches were carried out in January 2021, to fnd all relevant literature for this review, as well as through searching additional sources. Eligible studies were quantitative primary research, focusing on the use of fast-track admission pathway care versus usual care, for adults with a hip fracture. The assessment of study suitability, data extraction, and critical appraisal was carried out by two independent authors. A narrative analysis of the data was conducted, and data were meta-analysed using RevMan where possible. Quality appraisal of the included studies was undertaken using the EBL checklist. RESULTS: Seven studies reporting data on 5723 patients were included. Length of stay, time to surgery, and mortality did not difer signifcantly between the fast-track care, and usual care. One study reported on delirium and found statistically signifcantly fewer encounters of delirium in fast-track care versus usual care. Four of the seven studies satisfed rigorous quality appraisal (>75%) using the EBL. CONCLUSION: The fast-track pathway avoided unnecessary delays in emergency departments due to faster X-rays, direct admission to orthopaedic wards, and reduced delirium rates. However, results were unable to show the impact of fast-track on length of stay, time to surgery, and mortality

Background: Multiple studies and meta-analyses have reported the diagnostic value of C-reactive protein (CRP) in several diseases. However, the precision, and influence of potential bias regarding the diagnostic values of existing evidence may have implications for clinical practice. Methods: We performed an umbrella review of diagnostic test accuracy studies of CRP for diseases by searching PubMed, Embase, China National Knowledge Infrastructure, and WanFang databases up to March 7, 2021. Five independent reviewers evaluated eligibility, extracted data, and assessed methodological quality. We descriptively analyzed the diagnostic accuracy of CRP for multiple diseases, heterogeneity between studies, and publication bias. Results: Seventy-four meta-analyses were included, with 13 diseases classified according to the International Classification of Diseases-11 (ICD-11). The methodological quality of the included meta-analyses was mostly low, with only 16 meta-analyses rated as moderate or high, including seven diseases classified by ICD-11. CRP had a relatively greater diagnostic accuracy for two of these diseases. For postoperative infectious complications after bariatric surgery, sensitivity and specificity were 0.81 (0.34-1) and 0.91 (0.73-1), respectively. For anastomotic leakage after colorectal surgery, sensitivity and specificity were 0.95 (0.75-0.99) and 0.95 (0.75-0.99), respectively. Conclusions: The diagnostic accuracy of CRP for multiple diseases has been extensively studied; however, most studies have low methodological quality. Evidence indicates that CRP has a relatively greater diagnostic accuracy for inflammation and infection diseases, especially for postoperative infectious complications after bariatric surgery and anastomotic leakage after colorectal surgery.

OBJECTIVE: Virtual (VR), augmented (AR), mixed reality (MR) and haptic interfaces make additional avenues available for surgeon assessment, guidance and training. We evaluated applications for open trauma and emergency surgery to address the question: Have new computer-supported interface developments occurred that could improve trauma training for civilian and military surgeons performing open, emergency, non-laparoscopic surgery? DESIGN: Systematic literature review. SETTING AND PARTICIPANTS: Faculty, University of Maryland School of Medicine, Baltimore., Maryland; Womack Army Medical Center, Fort Bragg, North Carolina; Temple University, Philadelphia, Pennsylvania; Uniformed Services University of Health Sciences, and Walter Reed National Military Medical Center, Bethesda, Maryland. METHODS: Structured literature searches identified studies using terms for virtual, augmented, mixed reality and haptics, as well as specific procedures in trauma training courses. Reporting bias was assessed. Study quality was evaluated by the Kirkpatrick's Level of evidence and the Machine Learning to Asses Surgical Expertise (MLASE) score. RESULTS: Of 422 papers identified, 14 met inclusion criteria, included 282 enrolled subjects, 20% were surgeons, the remainder students, medics and non-surgeon physicians. Study design was poor and sample sizes were low. No data analyses were beyond descriptive and the highest outcome types were procedural success, subjective self-reports, except three studies used validated metrics. Among the 14 studies, Kirkpatrick's level of evidence was level zero in five studies, level 1 in 8 and level 2 in one. Only one study had MLASE Score greater than 9/20. There was a high risk of bias in 6 studies, uncertain bias in 5 studies and low risk of bias in 3 studies. CONCLUSIONS: There was inadequate evidence that VR,MR,AR or haptic interfaces can facilitate training for open trauma surgery or replace cadavers. Because of limited testing in surgeons, deficient study and technology design, risk of reporting bias, no current well-designed studies of computer-supported technologies have shown benefit for open trauma, emergency surgery nor has their use shown improved patient outcomes. Larger more rigorously designed studies and evaluations by experienced surgeons are required for a greater variety of procedures and skills. COMPETENCIES: Medical Knowledge, Practice Based Learning and Improvement, Patient Care, Systems-Based Practice.

INTRODUCTION: Bariatric surgery (BS) has been shown to effectively treat morbid obesity and improve obesity-related comorbidities. Nonetheless, BS remains underutilized among qualified patients. MATERIALS AND METHODS: PubMed, SCOPUS, and OVID databases were searched to identify published comparative studies examining BS referral patterns. Data on barriers to BS referrals were examined and summarized. RESULTS: Barriers to referrals stemmed largely from a lack of familiarity with safety, efficacy, and postoperative care amongst providers. Providers with previous referrals were more likely to report higher knowledge, comfort in referring patients, and ability to provide postoperative care. Provider initiated discussion of BS was positively associated with referrals. Female and younger patients were more likely to receive referrals. Furthermore, access to appropriate peri-operative resources, local bariatric programs, and insurance eligibility were associated with referral rates. Encouragingly, providers across specialties report eagerness to gain exposure and training in BS. CONCLUSIONS: Lack of provider familiarity with BS efficacy, safety and postoperative care likely contributes to low utilization rates of BS. Further potential barriers in access to BS are logistic factors such as insurance coverage, limited local perioperative resources, and clinic time constraints for patient counseling. Promotion of BS amongst providers and both surgical and non-surgical trainees will likely have a significant impact on referral rates and access to this life-saving procedure. Future studies should further investigate the barriers to BS and delineate the effect size of each barrier on referral rates to efficiently increase access.

PURPOSE: To describe the clinical and preclinical research conducted on primary repair of the anterior cruciate ligament (ACL) during the past 10 years. METHODS: A systematic search of PubMed, the Cochrane Central Register of Controlled Trials, and Embase was performed for all English-language studies published between 2003 and April 2014 on primary repair of the ACL. RESULTS: Twenty-six studies met the inclusion and exclusion criteria. In the clinical research group, 8 studies (166 patients; age range, 10 to 71 years) met the inclusion and exclusion criteria and were largely long-term clinical outcome studies, based on the original cohorts from the 1970s and 1980s, and suggested high failure rates, additional surgery, and revision for instability. A subset of patients, however, achieved good to excellent subjective and objective long-term outcomes. In the preclinical research group, 18 studies met the inclusion and exclusion criteria and were based on an ACL tran model; they suggested that (1) stabilization of the knee with an internal suture strut improved the healing and biomechanical properties of the repaired ACL, (2) 'enhancing' the repair with biological collagen-platelet composite augmentation improved healing and mechanical strength, (3) younger age and skeletal immaturity seem to correlate with improved histologic healing and biomechanical properties, (4) enhanced primary repair of the ACL may reduce post-traumatic osteoarthritis, and (5) the native ACL biomechanically outperformed the repaired ACL. CONCLUSIONS: Although long-term human studies suggest collectively unacceptable outcomes for open primary repair of the ACL, a subset of patients achieved acceptable long-term results. ACL tran model animal studies showed improved healing and biomechanics with primary suture repair stabilization, early intervention, biological augmentation techniques, and younger age. Primary repair of the ACL may be an effective treatment modality for an appropriately selected subset of patients. LEVEL OF EVIDENCE: Level IV, systematic review of preclinical and clinical Level IV studies

Objective To comprehensively analyze the cost-utility of robotic surgery in clinical practice and to investigate the reporting and methodological quality of the related evidence. Methods Data on cost-utility analyses (CUAs) of robotic surgery were collected in seven electronic databases from the inception to July 2021. The quality of the included studies was assessed using the CHEERs and QHES checklists. A systematic review was performed with the incremental cost-effectiveness ratio as the outcome of interest. Results Thirty-one CUAs of robotic surgery were eligible. Overall, the identified CUAs were fair to high quality, and 63% of the CUAs ranked the cost-utility of robotic surgery as “favored,” 32% categorized as “reject,” and the remaining 5% ranked as “unclear.” Although a high heterogeneity was present in terms of the study design among the included CUAs, most studies (81.25%) consistently found that robotic surgery was more cost-utility than open surgery for prostatectomy (ICER: $6905.31/QALY to $26240.75/QALY; time horizon: 10 years or lifetime), colectomy (dominated by robotic surgery; time horizon: 1 year), knee arthroplasty (ICER: $1134.22/QALY to $1232.27/QALY; time horizon: lifetime), gastrectomy (dominated by robotic surgery; time horizon: 1 year), spine surgery (ICER: $17707.27/QALY; time horizon: 1 year), and cystectomy (ICER: $3154.46/QALY; time horizon: 3 months). However, inconsistent evidence was found for the cost-utility of robotic surgery versus laparoscopic surgery and (chemo)radiotherapy. Conclusions Fair or high-quality evidence indicated that robotic surgery is more cost-utility than open surgery, while it remains inconclusive whether robotic surgery is more cost-utility than laparoscopic surgery and (chemo)radiotherapy. Thus, an additional evaluation is required.

BACKGROUND: The use of three-dimensional (3D) printing in neurosurgery has become more prominent in recent years for surgical training, preoperative planning, and patient education. Several smaller studies are available using 3D printing; however, there is a lack of a concise review. This article provides a systematic review of 3D models in use by neurosurgical residents, with emphasis on training, learning, and simulation. METHODS: A structured literature search of PubMed and Embase was conducted using PRISMA guidelines to identify publications specific to 3D models trialed on neurosurgical residents. Criteria for eligibility included articles discussing only neurosurgery, 3D models in neurosurgery, and models specifically tested or trialed on residents. RESULTS: Overall, 40 articles were identified that met inclusion criteria. These studies encompassed different neurosurgical areas including aneurysm, spine, craniosynostosis, transsphenoidal, craniotomy, skull base, and tumor. Most articles were related to brain surgery. Of these studies, vascular surgery had the highest overall, with 13 of 40 articles, which include aneurysm clipping and other neurovascular surgeries. Twenty-two articles discussed cranial plus tumor surgeries, which included skull base, craniotomy, craniosynostosis, and transsphenoidal. Five studies were specific to spine surgery. Subjective outcome measures of neurosurgical residents were most commonly implemented, of which results were almost unanimously positive. CONCLUSIONS: 3D printing technology is rapidly expanding in health care and neurosurgery in particular. The technology is quickly improving, and several studies have shown the effectiveness of 3D printing for neurosurgical residency education and training.

BACKGROUND: Very little is known about the state of surgical, anaesthesia and obstetric care in Pakistan. AIMS: This study aimed to assess the literature available on surgical, anaesthesia and obstetric care in Pakistan to understand the strengths and weaknesses of this care based on the domains of the framework of national surgical obstetric anaesthesia plans, namely: infrastructure, workforce, service delivery, information management, governance and service delivery. METHODS: Relevant studies in English published between 2003 and 2018 were identified by searching electronic databases including PubMed/MEDLINE, EMBASE and Scopus. Searches of the grey literature were also done for documents of various organizations. Thematic content analysis was conducted to collate, summarize and analyse the data. RESULTS: A total of 2347 studies were identified and screened, of which 57 articles met the inclusion criteria. While national-level surveys, reviews and policy documents provided an understanding of the existing surgical, anaesthesia and obstetric care services in the country, most of the studies were limited in their scope and therefore were not representative of the situation at the national level. In terms of surgical, anaesthesia and obstetric care, the health care infrastructure, availability of services, workforce, financial protection, information management and governance frameworks have failed to develop at the same pace as the needs of the ever-growing population in Pakistan. CONCLUSIONS: Our findings can be used to guide future research activities as part of efforts to strengthen the surgical system in Pakistan. Recent government initiatives hold promise for future improvement in access to surgical care.

BACKGROUND: Electronic consultations (eConsults) are an increasingly used form of telemedicine that allows a nonspecialist clinician to seek specialist advice remotely without direct patient-specialist communication. Surgical clinics may see benefits from such forms of communication but face challenges with the need for intervention planning. OBJECTIVE: We aimed to use the Quadruple Aim Framework to integrate published knowledge of surgical outpatient eConsults with regard to efficacy, safety, limitations, and evolving use in the era of COVID-19. METHODS: We systematically searched for relevant studies across four databases (Ovid MEDLINE, Embase, Scopus, and Web of Science) on November 4, 2021, with the following inclusion criteria: English language, published in the past 10 years, and data on the outcomes of outpatient surgical eConsults. RESULTS: A total of 363 studies were screened for eligibility, of which 33 (9.1%) were included. Most of the included studies were from the United States (23/33, 70%) and Canada (7/33, 21%), with a predominant multidisciplinary focus (9/33, 27%). Most were retrospective audits (16/33, 48%), with 15% (5/33) of the studies having a prospective component. CONCLUSIONS: The surgical eConsult studies indicated a possible benefit for population health, promising safety results, enhanced patient and clinician experience, and cost savings compared with the traditional face-to-face surgical referral pathway. Their use appeared to be more favorable in some surgical subspecialties, and the overall efficacy was similar to that of medical subspecialties. Limited data on their long-term safety and use during the COVID-19 pandemic were identified, and this should be the focus of future research.

Background In the last 30 years, significant progress in the field of surgery has been achieved with the advent of robotic surgery. In this study, we aimed to conduct a bibliometric analysis to identify the distribution and characteristics overall and of the top 100 most-cited studies about robotic surgery versus open surgery. Methods A systematic search was conducted on March 26, 2021 using Web of Science Core Collection. Two reviewers independently screened documents, and the top 100 most-cited studies were identified. Excel 2019 and VOSviewer were used to collect the data, and visual information was obtained. Results A total of 2306 documents were searched from the Web of Science Core Collection, and 1065 journals and 2913 institutes were extracted. A significant growth was observed in the last 15 years. The number of citations from the United States accounted for 33.31% of the total number of citations. There were nine American institutes and one Swedish institute in the top 10 institutes. Four journals in the field of urology or gynecology were present in the top 10 published journals. Few global communications between authors, institutes, and countries authors were observed. Conclusion The lack of close cooperation among scientific research institutions may have affected the industrialization process of surgical robots. Some developing countries, including South America and Africa, should seize the development opportunity of robotic surgery to improve the level of domestic research on robotic surgery.

The COVID-19 pandemic has disrupted neurosurgical training worldwide, with the shutdown of academic institutions and the reduction of elective surgical procedures. This impact has disproportionately affected LMICs (lower- and/or middle-income countries), already burdened by a lack of neurosurgical resources. Thus, a systematic review was conducted to examine these challenges and innovations developed to adapt effective teaching and learning for medical students and neurosurgical trainees. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) and The Cochrane Handbook of Systematic Reviews of Interventions. MEDLINE, PubMed, Embase and Cochrane databases were accessed, searching and screening literature from December 2019 to 5th December 2020 with set inclusion and exclusion criteria. Screening identified 1254 articles of which 26 were included, providing data from 96 countries. Twenty-three studies reported transition to online learning, with 8 studies also mentioned redeployment into COVID wards with 2 studies mentioning missed surgical exposure as a consequence. Of 7 studies conducted in LMICs, 3 reported residents suffering financial insecurities from reduced surgical caseload and recession. Significant global disruption in neurosurgical teaching and training has arisen from the COVID-19 pandemic. Decreased surgical exposure has negatively impacted educational provision. However, advancements in virtual technology have allowed for more affordable, accessible training especially in LMICs. Using this, initiatives to reduce physical and mental stress experienced by trainees should be paramount.
