RESUMEN
OBJECTIVE: Our primary objective was to compare the intraoperative costs of 3 different surgical visualization techniques for anterior cervical discectomy and fusion (ACDF). Specifically, we used time-driven activity-based costing (TDABC) methodology to compare costs between ACDFs performed with operative microscopes (OM-ACDF), exoscopes (EX-ACDF), and loupes (loupes-ACDF). METHODS: Total cost was divided into direct and indirect costs. Individual costs were obtained by direct observation, electronic medical records, and through querying multiple departments (business operations, sterile processing, plant operations, and pharmacy). Timestamps for all involved personnel and material resources were documented. We identified all instances of loupes-ACDF (n = 882), EX-ACDF (n = 26), and OM-ACDF (n = 52) performed at our institution. We performed multivariable linear regression analyses to compare costs between these modalities, accounting for patient-specific factors as well as number of levels fused, surgeon, and hospital site. RESULTS: The average total intraoperative costs per loupes-ACDF, EX-ACDF, and OM-ACDF cases were $7081 +/- $2,942, $7951 +/- $3,488, and $6557 +/- $954, respectively. Regression analysis revealed no difference in intraoperative cost between loupes-ACDF and EX-ACDF (P = 0.717), loupes-ACDF and OM-ACDF (0.954), or OM-ACDF and EX-ACDF (0.217). On a more granular level, however, EX-ACDF was associated with increased cost of consumables, including drapes, compared to both OM-ACDF (ß-coefficient: $369 +/- $121, P = 0.002) and loupes-ACDF (ß-coefficient: $284 +/- $86, P = 0.001). CONCLUSIONS: Although hospitals may be aware of the purchasing fees associated with microscopes and exoscopes, there is no clear documentation of how these technologies affect intraoperative cost. We demonstrate a novel use of TDABC for this purpose.

Traumatic spinal cord injury (SCI) causes a sudden onset multi-system disease, permanently altering homeostasis with multiple complications. Consequences include aberrant neuronal circuits, multiple organ system dysfunctions, and chronic phenotypes such as neuropathic pain and metabolic syndrome. Reductionist approaches are used to classify SCI patients based on residual neurological function. Still, recovery varies due to interacting variables, including individual biology, comorbidities, complications, therapeutic side effects, and socioeconomic influences for which data integration methods are lacking. Infections, pressure sores, and heterotopic ossification are known recovery modifiers. However, the molecular pathobiology of the disease-modifying factors altering the neurological recovery-chronic syndrome trajectory is mainly unknown, with significant data gaps between intensive early treatment and chronic phases. Changes in organ function such as gut dysbiosis, adrenal dysregulation, fatty liver, muscle loss, and autonomic dysregulation disrupt homeostasis, generating progression-driving allostatic load. Interactions between interdependent systems produce emergent effects, such as resilience, that preclude single mechanism interpretations. Due to many interacting variables in individuals, substantiating the effects of treatments to improve neurological outcomes is difficult. Acute injury outcome predictors, including blood and cerebrospinal fluid biomarkers, neuroimaging signal changes, and autonomic system abnormalities, often do not predict chronic SCI syndrome phenotypes. In systems medicine, network analysis of bioinformatics data is used to derive molecular control modules. To better understand the evolution from acute SCI to chronic SCI multi-system states, we propose a topological phenotype framework integrating bioinformatics, physiological data, and allostatic load tested against accepted established recovery metrics. This form of correlational phenotyping may reveal critical nodal points for intervention to improve recovery trajectories. This study examines the limitations of current classifications of SCI and how these can evolve through systems medicine.

OBJECTIVE: The objective of this study is to explore the perception of teachers, parents and students' regarding implementation of a school-based lifesaving skills program and help predict potential barriers and solutions. METHODS: This qualitative exploratory study was conducted in Karachi, Pakistan, from December 2020- to October 2021. We included students, teachers, and parents of secondary (grades VIII, IX, and X) and higher secondary level students (grades XI and XII) in Karachi, Pakistan's public and private schools and colleges. We selected one public, two semi-private, and two private schools. We recruited students, teachers, and parents through convenience sampling. We conducted fifteen focus group discussions (FGDs) with the students, six FGDs with the teachers, and eighteen in-depth interviews (IDIs) with parents. We transcribed the data from audio recordings and translated it into the English language. Finally, we manually analyzed the data using thematic analyses. RESULTS: This study found that bystanders' main barriers to performing lifesaving skills are lack of knowledge, fear of legal involvement, fear of hurting the patient by incorrect technique, lack of empathy among community stakeholders, and gender bias. However, the participants had a positive and supportive attitude toward implementing lifesaving skills training in schools. They suggested starting student training in the early teenage years, preferred medical staff as trainers, and suggested frequent small sessions in English/Urdu both or Urdu language and training via theory and practical hands-on drills. Furthermore, the training was proposed to be integrated into the school curriculum to make it sustainable. Finally, the government needs to support the program and make the legal environment more conducive for bystanders. CONCLUSION: This study identified the significant barriers to performing lifesaving skills in an emergency in a low- and middle-income country (LMIC). The participants supported implementing a national lifesaving skills program in schools and colleges. However, the participants expressed that support is needed by the government for sustainability, integrating lifesaving skills into the school curriculum, providing legal support to the bystanders, and creating awareness among the general public.

STUDY DESIGN: A multi-disciplinary review. OBJECTIVES: To provide a roadmap for implementing time-driven activity-based costing (TDABC) for spine surgery. This is achieved by organizing and scrutinizing publications in the spine, neurosurgical, and orthopedic literature which utilize TDABC and related methodologies. METHODS: PubMed and Google Scholar were searched for relevant articles. The articles were selected by two independent researchers. After article selection, data was extracted and summarized into research domains. Preferred reporting items for systematic reviews and meta-analyses (PRISMA) systematic review process was followed. RESULTS: Of the 524 articles screened, thirty-five articles met the inclusion criteria. Each included article was examined and reviewed to define the primary research question and objective. Comparing different procedures was the most common primary objective. Direct observation along with one other strategy (surveys, interviews, surgical database, or EMR) was most commonly employed during process map development. Across all surgical subspecialties (spine, neurologic, and orthopedic surgery), costs were divided into direct cost, indirect cost, cost to patient, and total costs. The most commonly calculated direct costs included personnel and supply costs. Facility costs, hospital overhead costs, and utilities were the most commonly calculated indirect costs. Transportation costs and parental lost wages were considered when calculating cost to patient. The total cost was a sum of direct costs, indirect costs, and costs to the patient. CONCLUSION: TDABC provides a common platform to accurately estimate costs of care delivery. Institutions embarking on TDABC for spine surgery should consider the breadth of methodologies highlighted in this review to determine which type of calculations are appropriate for their practice.
RESUMEN
OBJECTIVES: To compile intra-operative techniques, established imaging parameters, available equipment and software, and clinical applications of intraoperative ultrasound imaging (IOUSI) for spinal cord injury (SCI) and myelopathy. METHODS: PubMed and Google Scholar were searched for relevant articles. The articles were reviewed and selected by 2 independent researchers. After article selection, data were extracted and summarized into research domains. PRISMA systematic review process was followed. RESULTS: Of the 2477 articles screened, 16 articles met the inclusion criteria. In patients with SCI and myelopathy, common quantitative measurements obtained using IOUSI were noted: 1) ultrasound elastography, 2) midsagittal anteroposterior diameter, 3) transverse, 4) transverse diameter, 5) maximum spinal cord compression, and 6) compression ratioTo ensure adequate decompression and to look for residual compression, the lateral and the craniocaudal margins of the laminectomy site were inspected in both axial and sagittal planes. In instances where quantitative assessment was not possible, cord decompression and degree of residual compression were gauged by inspecting the interface between the ventral border of the spinal cord and any potentially compressive elements, and by searching for symmetric and rhythmic cerebrospinal fluid pulsations. Use of contrast-enhanced ultrasoundand molecular imaging are additional advances in objective assessments for SCI and myelopathy. CONCLUSIONS: This review outlines the potential of IOUSI in patients presenting with SCI and myelopathy. Moreover, by identifying potential for inter-operator variability in certain subjective measurements, we illustrate the need for further research to quantify and standardize those assessments.

Objectives: This study aims to identify the effect of having COVID-19 positive close contact on practices and evaluate practices regarding COVID-19 prevention among medical students and the differences among clinical and preclinical students. Study design: The cross-sectional study included medical students from the Micro-fest++ event held on 30th May 2020. Methods: Participants filled a questionnaire of 15 questions regarding COVID preventive measures practices having satisfactory reliability (Cronbach's alpha = 0.715) and validity. The Statistical Package for Social Sciences (IBM SPSS) 26.0 was used for data analysis. Out of 1342 medical students, the majority were female (N = 881, 65.6%). Greater proportion (47%) of students had good practices (>85.7%) (p < 0.05). Results: Having COVID-19 positive relatives resulted in higher positive responses for practices with 11.86 ± 1.94 (out of 14) compared to 11.78 ± 2.38 for the COVID-19 negative group. Clinical year students compared to preclinical students responded positively to all questions, except one, and had a better score of 11.90 ± 2.28 (out of 14) compared to 11.61 ± 2.37 (p < 0.05). A significant difference was noted for "Information on preventive measures" (p < 0.01), "Avoiding crowds and staying home" (p < 0.05), "Social distancing (maintain 3 feet)" (p < 0.01), and "Practices of disinfection after going outside" (p < 0.05). Conclusions: Overall, medical students showed good practices, but a lack of knowledge in certain areas requires addressing infection during clinical rotations. A greater proportion of clinical students and those having a COVID-19 positive relative showed better adherence to practices.
RESUMEN
BACKGROUND: This study aimed to document the evolution of perceptions of frontline healthcare workers (FHCW) regarding their well-being and the quality of health systems' response to the COVID-19 pandemic over four months in Pakistan. METHODS: We conducted this prospective longitudinal qualitative study during the four months (June-September 2020) coinciding with the peak and trough of the first wave of Pakistan's COVID-19 pandemic. We approached frontline healthcare workers (physicians and nurses) working in emergency departments (ED) in two hospitals using the WhatsApp group of the Pakistan Society of Emergency Physicians (PSEM). Participants were asked to self-record their perception of their wellness and their level of satisfaction with the quality of their hospitals' response to the pandemic. We transcribed, translated, and analysed manually using MAXQDA 2020 software and conducted the thematic analysis to identify themes and sub-themes. RESULTS: We invited approximately 200 FHCWs associated with PSEM to participate in the study. Of the 61 who agreed to participate, 27 completed the study. A total of 149 audio recordings were received and transcribed. Three themes and eight sub-themes have emerged from the data. The themes were individual-level challenges, health system-level challenges, and hope for the future. Sub-themes for individual-level challenges were: fear of getting or transmitting infection, feeling demotivated and unappreciated, disappointment due to people's lack of compliance with COVID-19 protocols, physical exhaustion, and fatigue. For the healthcare system, sub-themes were: Infrastructure, logistics, management, and communications response of the hospital/healthcare system and financial stressors. For sub-themes under hope for the future were the improved disease knowledge and vaccine development. The overall perceptions and experiences of FHCWs evolved from fear, grief, and negativity to hope and positivity as the curve of COVID-19 went down. CONCLUSION: This study shows that the individuals and systems were not prepared to deal with the challenges of the COVID-19 pandemic. The findings highlight the challenges faced by individuals and health systems during the wake of the Covid-19 pandemic. The healthcare workers were emotionally and physically taxed, while the health systems were overwhelmed by COVID-19. The overall perceptions of FHCWs evolved with time and became negative to positive as the curve of COVID-19 went down during the first wave of COVID-19 in Pakistan.

BACKGROUND: Traditional, instructor led, in-person training of CPR skills has become more challenging due to COVID-19 pandemic. We compared the learning outcomes of standard in-person CPR training (ST) with alternative methods of training such as hybrid or online-only training (AT) on CPR performance, quality, and knowledge among laypersons with no previous CPR training. METHODS: We searched PubMed and Google Scholar for relevant articles from January 1995 to May 2020. Covidence was used to review articles by two independent researchers. Effective Public Health Practice Project (EPHPP) Quality Assessment Tool was used to assess quality of the manuscripts. RESULTS: Of the 978 articles screened, twenty met the final inclusion criteria. All included studies had an experimental design and moderate to strong global quality rating. The trainees in ST group performed better on calling 911, time to initiate chest compressions, hand placement and chest compression depth. Trainees in AT group performed better in assessing scene safety, calling for help, response time including initiating first rescue breathing, adequate ventilation volume, compression rates, shorter hands-off time, confidence, willingness to perform CPR, ability to follow CPR algorithm, and equivalent or better knowledge retention than standard teaching methodology. CONCLUSION: AT methods of CPR training provide an effective alternative to the standard in-person CPR for large scale public training.

BACKGROUND: Coronavirus disease (COVID-19) pandemic has spread to 198 countries, with approximately 2.4 million confirmed cases and 150,000 deaths globally as of April 18. Frontline healthcare workers (HCWs) face a substantially higher risk of infection and death due to excessive COVID-19 exposure. This review aimed at summarizing the evidence of the physical and mental health impacts of COVID-19 pandemic on health-care workers (HCWs). METHODS: We used the Arksey O'Malley framework to conduct a scoping review. A systematic literature search was conducted using two databases: PubMed and Google Scholar. We found 154 studies, and out of which 10 met our criteria. We collected information on the date of publication, first author's country, the title of the article, study design, study population, intervention and outcome, and key findings, and divided all research articles into two domains: physical and mental health impact. RESULTS: We reviewed a total of 154 articles from PubMed (126) and Google Scholar (28), of which 58 were found to be duplicate articles and were excluded. Of the remaining 96 articles, 82 were excluded after screening for eligibility, and 4 articles did not have available full texts. Ten full-text articles were reviewed and included in this study. Our findings identified the following risk factors for COVID-19-related health impact: working in a high-risk department, diagnosed family member, inadequate hand hygiene, suboptimal hand hygiene before and after contact with patients, improper PPE use, close contact with patients (≥ 12 times/day), long daily contact hours (≥ 15 h), and unprotected exposure. The most common symptoms identified amongst HCWs were fever (85%), cough (70%), and weakness (70%). Prolonged PPE usage led to cutaneous manifestations and skin damage (97%), with the nasal bridge (83%) most commonly affected site. HCWs experienced high levels of depression, anxiety, insomnia, and distress. Female HCWs and nurses were disproportionately affected. CONCLUSION: The frontline healthcare workers are at risk of physical and mental consequences directly as the result of providing care to patients with COVID-19. Even though there are few intervention studies, early data suggest implementation strategies to reduce the chances of infections, shorter shift lengths, and mechanisms for mental health support could reduce the morbidity and mortality amongst HCWs.
