ABSTRACT

An organizational crisis is a low-probability, high-impact event that threatens the survival of organizations and individuals, often with little warning. In response, people seek clarity, reassurance, and hope from organiza-tional leaders. Yet, crises also vary in nature and impact (e.g., a product failure versus the COVID-19 pan-demic), which presents diverse challenges to leaders and differing stakeholder perceptions. Based on a critical analysis of 69 empirical articles, we provide a comprehensive, systematic, interdisciplinary review of the crisis leadership literature. Our review utilizes the Coombs and Holladay (1996) crisis typology, where crises are categorized according to mutually exclusive attributional dimensions (i.e., internal-external and intentional-unintentional). We conduct a thematic analysis of crisis leadership within and across these four cri-sis categories and find that each is associated with a different leadership theme. We also examine the method-ological quality and rigor of the qualitative and quantitative articles in our review. Based on our findings, we also offer suggestions to guide future crisis leadership research, and provide guidance for organizational lead-ers in how to respond to various crises.

ABSTRACT

Extracorporeal Membrane Oxygenation is a resource intensive therapy;heavily reliant upon specialized equipment, unique disposables, and skilled staff. The Covid-19 pandemic and following events exposed flaws in multiple phases of the care delivery system. The combination of high patient census, acuity, manufacturing delays, and supply chain disruptions led to our center's reassessment of the way in which limited resources are utilized. As a combined pediatric and adult center, we possess the ability to share resources amongst all patient populations. Currently, the majority of our equipment and disposables support a heavier use of Centrimag. We adjusted our general weight guidelines in order to best serve the most patients. (<8kg Sorin Rollerhead, 8-20kg Sorin Revolution, >20kg Centrimag.) Presently, a major challenge is the cessation of production of the -inch Better Bladder. The ECMO Coordinator team collaborated with key physician stakeholders. It was decided that the fluid reservoir and air trap benefits of a bladder outweighed the risks of running without one on our Sorin Rollerhead circuit. We designed a circuit with a 3/8 Bigger Better Bladder. Recognizing the increased risk of clotting with the 3/8 segment, we added a post-oxygenator shunt. This allows for adequate blood flow to maintain circuit integrity, while limiting the amount of flow to the patient. The nationwide nursing shortage is well-known. Though our multidisciplinary ECMO Specialist Team supports nursing and respiratory therapy, the nursing shortage still impacts our staffing models, resulting in the inability to safely staff bedside nurses and ECMO specialists. At times of high census, ECMO patients are cohorted into one geographical location. This allows for a temporary 2:1 staffing model for Centrimag patients. Our goal remains to staff pediatric cases as a 1:1 ECMO Specialist assignment. The ability to obtain this is assessed shift to shift;factoring patient stability, experience of the ECMO specialist, and unit staffing. The collaboration with ICU Nurse Managers, Hospital Supervisors and Central Staffing Office is imperative to the success of staffing model alterations. Our ECMO department has increased its FTEs, implementing a core team to be preassigned to two ECMO beds. The objective is to alleviate the burden on ICU staffing, limiting the number of nurses pulled from staffing grids. In uncertain times, flexibility is vital. It is important to remain vigilant and proactive. Our ECMO program feels that continuous assessment of supplies, equipment, and open communication has been the key to successfully serving our patients.

ABSTRACT

Internships can serve as a pipeline to employers and have played an important role in hospitality education programs. The COVID-19 Pandemic has moved many internships online limiting student benefits and options. As the hospitality industry struggles to compete in the post-Coronavirus labor market, it has never been more important to ensure highly satisfying internship experiences. Findings indicate that host sites permitting student interns to be creative and feel appreciated while identifying long-term career opportunities produce more satisfied interns. While satisfaction may be enhanced when supervisors mentor their interns by building strong Leader-Member Exchange relationships, they may not be required for intern satisfaction. © 2023 Taylor & Francis Group, LLC.

ABSTRACT

The COVID-19 pandemic tasked affected healthcare programs to find creative solutions for preserving staff competency amidst high staffing turnover, limited resources, and increased patient acuity. In 2022, our ECMO leadership team aimed to provide additional educational resources to our ECMO specialist team, without adding to the workload of staff burnout. Prior to 2020, our educational structure involved an extensive onboarding process for new ECMO specialists, quarterly hands-on drill simulations, and a yearly recertification exam. From 2020 to 2021, we saw a significant amount of turnover within our ECMO department amidst the pandemic. We ended 2020 with 36 specialists and 2021 with 18 specialists, hiring 12 new specialists. Our ECMO census continued to increase with 72 total runs and average daily census of 2.2 in 2021, up to 99 total runs and average daily census of 2.4 in 2022. 2021 ELSO data showed that 60% of our patient runs contained mechanical errors including air entrainment, cannula problems, circuit exchanges, oxygenator failure, and thrombosis. In order to support our staff with so many new specialists who are expected to care for a higher quantity of patients with more complex morbidities, at the same exceptional quality as our most senior staff, we provided a variety of additional educational resources in 2022. Visual aids were created for our 3 ECMO pumps including pump physiology, basic handling skills, emergencies, and advanced scenarios. We also created a pocket guide combining the educational information taught in the onboarding class with other various resources provided to our staff. ECMO staff members can keep the pocket guide to reference, and to add their own notes as needed. Lastly, a monthly newsletter sent to our staff, containing programmatic updates, educational tips and quizzes, reminders, and helpful links. After surveying our specialists at the end of 2022, we found that >80% of the specialists watch the videos before or during shifts, 100% watch the videos to prepare for water drills, and >80% own a pocket guide. 75% found the additional resources helpful to succeed in water drills and staying prepared to sit pump. Our 2022 ELSO data also showed a decrease to 43% of patient runs containing mechanical errors. MUSC is ELSO-designated platinum-level for both the pediatric and adult ECMO program, signifying the highest level of performance, innovation, satisfaction, and quality. Our goal is to use current practices combined with mentioned innovative strategies to retain this status in the upcoming year.

ABSTRACT

Introduction (contexte de la recherche): In Parts A and B of the 3-part phase 3 LIBERTY EoE TREET study (NCT03633617), dupilumab 300 mg weekly (DPL qw) vs. placebo (PBO) demonstrated significant efficacy and acceptable safety up to 24 weeks (wks) in adults and adolescents with eosinophilic esophagitis (EoE). For patients (pts) who completed Parts A or B, Part C was an extended active treatment period for 28 wks. Objectif: To assess the safety and efficacy of DPL in pts who completed Part B and continued to Part C, up to 52 wks. Methodes: Of 80 DPL qw pts in Part B, 74 continued DPL qw in Part C (DPL/DPL). Of 79 PBO pts in Part B, 37 pts received DPL qw in Part C (PBO/DPL). Part B co-primary endpoints were proportion of pts achieving peak esophageal intraepithelial eosinophil (eos) count <= 6 eos/high power field (hpf) and absolute change from Part B baseline (BL) in Dysphagia Symptom Score (DSQ) score at Wk 24. Secondary endpoints included peak eos count, EREFS, and HSS grade and stage scores. In Part C, all co-primary and secondary endpoints were assessed at Wk 52 as secondary endpoints. Safety was also assessed. Resultats: Part B BL characteristics were similar across groups. At Wk 52 of Part C, 84.6% of DPL/DPL and 67.6% of PBO/DPL groups achieved peak eos count of <= 6 eos/hpf and mean (SD) absolute change from Part B BL in DSQ score was -30.26 (15.39) for DPL/DPL and -27.25 (11.46) for PBO/DPL pts. At Wk 52, peak eos count, EREFS, HSS grade and stage scores were reduced, compared with Part B BL, and EDP and T2 NESs were suppressed in DPL/DPL and PBO/DPL groups. Dupilumab demonstrated an acceptable safety profile in Part C;the most common (occurring >= 10%) treatment-emergent adverse events in DPL/DPL and PBO/DPL groups were injection-site reactions (13.5% and 10.8%), COVID-19 (9.5% and 10.8%) and nasopharyngitis (4.1% and 10.8%). Conclusion(s): As observed in Part A/C, dupilumab qw demonstrated persistent improvements in clinical, symptomatic, histologic, endoscopic and molecular features of EoE up to 52 wks and had an acceptable safety profile. PBO pts from Part B who received dupilumab in Part C showed similar efficacy to dupilumab qw pts of Part B.Copyright © 2023

ABSTRACT

Pre-existing SARS-CoV-2-specific T cells, but not antibodies, have been detected in some unexposed individuals. This may account for some of the diversity in clinical outcomes ranging from asymptomatic infection to severe COVID-19. Although age is a risk factor for COVID-19, how age affects SARS-CoV-2-specific T cell responses remains unknown. We found that pre-existing T cell responses to specific SARS-CoV-2 proteins, Spike (S) and Nucleoprotein (N), were significantly lower in elderly donors (>70 years old) than in young donors. However, substantial pre-existing T cell responses to the viral membrane (M) protein were detected in both young and elderly donors. In contrast, young and elderly donors exhibited comparable T cell responses to S, N, and M proteins after infection with SARS-CoV-2. These data suggest that although SARS-CoV-2 infection can induce T cell responses specific to various viral antigens regardless of age, diversity of target antigen repertoire for long-lived memory T cells specific for SARS-CoV-2 may decline with age;however, memory T cell responses can be maintained by T cells reactive to specific viral proteins such as M. A better understanding of the role of pre-existing SARS-CoV-2-specific T cells that are less susceptible to age-related loss may contribute to development of more effective vaccines for elderly people.Copyright © 2021

ABSTRACT

Background and aims: As a result of disengagement in addiction care during the COVID-19 pandemic, there has been a record increase in mortality associated with opioid overdoses (primarily fentanyl), particularly in North America. In the USA there were over 100, 000 overdose deaths in 2021, while over 2000 were recorded in the province of British Columbia. As we attempt to develop novel ways to increase HCV treatment following ≥30% declines during the pandemic, we evaluated publicly available adverse events (AEs) reports for opioids and DAAs to assess whether safety concerns from potential drug interactions arewarranted, particularly amongst those using fentanyl. Method: Data were downloaded from the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) Public Dashboard. AEswith the DAAs glecaprevir/pibrentasvir (G/P), sofosbuvir/ velpatasvir (SOF/VEL), ledipasvir/sofosbuvir (LDV/SOF), sofosbuvir/ velpatasvir/voxilaprevir (SOF/VEL/VOX), andelbasvir/grazoprevir (EBR/ GZR) listed as the suspect product were analyzed with an initial received date from July 28, 2017-December 31, 2021, as were opioidassociated AEs for all 2017–2021. Subsequently, AEs were counted based on listed concomitant use of opioids (fentanyl, oxycodone, hydrocodone), or overdose outcomes irrespective of concomitant opioid use. Data are descriptivewithout any statistical analyses. Results: In the reporting period, 40 total AEs were recorded with concomitant DAA and fentanyl use, 14 resulting in death (G/p = 3, SOF/VEL = 11;Table 1);626 total AEs were recorded with concomitant DAA and oxycodone or hydrocodone use, 28 resulting in death. Separately, overdose events were reported 196 times, 32 resulting in death. The number of overdoses declined each year from 2018 (N = 56) to 2021 (N = 29). Fentanyl AEs showed no trend year to year. Table 1: FAERs AEs and deaths with opioids and with concomitant HCV DAAs. (Table Presented) *N represents the sum of fentanyl, oxycodone, and hydrocodone overdose AEs and deaths, whereas n’s for DAA overdose AEs and deaths are irrespective of concomitant opioids. Conclusion: With the limitations of FAERS data (under or duplicate reporting, inability to establish causation or incidence), these data showthat among ~58, 000 fentanyl, ~189, 000 oxycodone, and ~100, 000 hydrocodone AEs reported to FAERS since 2017, a small proportion (0.19%) have been reported in association with concomitant DAA therapy, with no association between recorded events and a specific DAA regimen. This should reassure HCV treaters on a lack of safety signal for concomitant opioid and DAA use.

ABSTRACT

Recombination is an evolutionary process by which many pathogens generate diversity and acquire novel functions. Although a common occurrence during coronavirus replication, detection of recombination is only feasible when genetically distinct viruses contemporaneously infect the same host. Here, we identify an instance of SARS-CoV-2 superinfection, whereby an individual was infected with two distinct viral variants: Alpha (B.1.1.7) and Epsilon (B.1.429). This superinfection was first noted when an Alpha genome sequence failed to exhibit the classic S gene target failure behavior used to track this variant. Full genome sequencing from four independent extracts reveals that Alpha variant alleles comprise around 75% of the genomes, whereas the Epsilon variant alleles comprise around 20% of the sample. Further investigation reveals the presence of numerous recombinant haplotypes spanning the genome, specifically in the spike, nucleocapsid, and ORF 8 coding regions. These findings support the potential for recombination to reshape SARS-CoV-2 genetic diversity.

ABSTRACT

The COVID-19 pandemic is one of the fastest evolving pandemics in recent history. As such, the SARS-CoV-2 viral evolution needs to be continuously tracked. This study sequenced 1123 SARS-CoV-2 genomes from patient isolates (121 from arriving travellers and 1002 from communities) to track the molecular evolution and spatio-temporal dynamics of the SARS-CoV-2 variants in Ghana. The data show that initial local transmission was dominated by B.1.1 lineage, but the second wave was overwhelmingly driven by the Alpha variant. Subsequently, an unheralded variant under monitoring, B.1.1.318, dominated transmission from April to June 2021 before being displaced by Delta variants, which were introduced into community transmission in May 2021. Mutational analysis indicated that variants that took hold in Ghana harboured transmission enhancing and immune escape spike substitutions. The observed rapid viral evolution demonstrates the potential for emergence of novel variants with greater mutational fitness as observed in other parts of the world.

ABSTRACT

Borders play a profound role in human life. In many settings, land borders are highly permeable and provide little barrier to movement, communication and interaction. In other circumstances, borders are highly rigid, difficult to cross and can demarcate vast economic and social disparities. The widely differing circumstances related to border creation and maintenance have deep effects that are worthy of social work attention and engagement. There has been serious attention to issues of globalisation, immigration and human rights in the social work literature. Our focus on borders is related to, but distinct from these issues, and therefore, has something unique to offer. Increased globalisation has led to a major reconceptualisation in our understanding of borders. The COVID-19 epidemic demonstrates the limited relevance of borders in some circumstances (spreading of the virus) but the heightened relevance of borders in other circumstances (travel restrictions). Social work practitioners have a role in framing the understanding of borders and resulting policies. Our focus is to address the question: How has social work engaged with border issues? We examine three international cases and conduct a comparative analysis to examine similarities and differences. From the analysis, we draw conclusions to further understanding for social work. Borders play a profound role in human life. This paper aims to examine how social work has engaged with borders. Conducting a comparative analysis of three international borders we describe impacts on practice and the profession. Noting similarities and differences we also assert generalisable conclusions and welcome engagement to further refine the analysis. Never before has it felt so timely to reflect on the issue of borders. The places that we come from have all been sharply affected by having land borders with neighbouring countries. At the time of writing, the contours of division that have marked our territorial separateness have come to the fore with COVID-19 restrictions impacting the movements of populations. Against this backdrop, social work has at its core an international definition and attendant global identity. Historically less clear is social work's position and stance adopted in dealing with borders. This paper is our attempt to bring attention to salient issues. First, by way of context, this topic will be examined within the context of key messages from literature.

ABSTRACT

Introduction Video consultation involves the live interaction between the doctor and the patient remotely. Prior to the Covid-19 pandemic, the majority of video consultations in primary care were provided by GPs who were not the individual's own GP, which presented safety and continuity issues. This study aims to determine GPs' attitudes to the use of video consultation for their own patients. Methods This was a qualitative study involving semi-structured interviews. Participants were purposively recruited through use of a GP tutor as a key informant and guided by a sampling framework to include those with and without previous video consultation experience. Braun and Clarke thematic analysis was used. Results Participants included eight GPs, half of whom had previously worked with video consultation. Four themes emerged: impact on the consultation, the potential role, and the potential threat to current practice and technology and logistics. There were optimistic and cautious observations within all themes. Conclusion With the increased use of video consultation, Irish General Practice is in a unique position to frame the future its use. The provision of this modality to one's own patients may provide benefit while mitigating some of the pitfalls but would not entirely avoid the potential dangers of video consultation.

ABSTRACT

Investment in Africa over the past year with regards to SARS-CoV-2 genotyping has led to a massive increase in the number of sequences, exceeding 100,000 genomes generated to track the pandemic on the continent. Our results show an increase in the number of African countries able to sequence within their own borders, coupled with a decrease in sequencing turnaround time. Findings from this genomic surveillance underscores the heterogeneous nature of the pandemic but we observe repeated dissemination of SARS-CoV-2 variants within the continent. Sustained investment for genomic surveillance in Africa is needed as the virus continues to evolve, particularly in the low vaccination landscape. These investments are very crucial for preparedness and response for future pathogen outbreaks.

These findings support the potential for recombination to reshape SARS-CoV-2 genetic diversity.

ABSTRACT

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARSCoV- 2) has resulted in a pandemic which has infected more than 128 million people and led to over 2.8 million deaths worldwide. Although the introduction of efficacious vaccines has led to overall declines in the incidence of SARS-CoV-2 infection, there has been a recent increase in infections once more due to the appearance of mutant strains with higher virulence. It therefore remains vital to identify predictors of poor outcomes in this patient population. Purpose: The objective of our study was to identify predictors of prolonged hospitalization, intensive care unit (ICU) admission, intubation, and death in patients infected with SARS-CoV-2. Methods: We conducted a retrospective analysis of all patients hospitalized with SARS-CoV-2 at our health system that includes one tertiary care center and two community hospitals located in the Chicago metropolitan area. The main outcome was a composite endpoint of hospitalization >28 days, ICU admission, intubation, and death. Explanatory variables associated with the primary outcome in the bivariate analysis (p<0.05) were included in the multivariable logistic regression model. Statistical analysis was performed using IBM SPSS 25.0. Results: Between March 1, 2020 and May 31, 2020, 1029 patients hospitalized with SARS-CoV-2 were included in our analysis. Of these patients, 379 met the composite endpoint. Baseline demographics are described in Table 1. Of note, our cohort consisted of a predominantly minority patient population including 47% Hispanic, 17% African American, 16% Caucasian, and 16% other. In bivariate analysis, age, hypertension, tobacco and alcohol abuse, obesity, coronary artery disease, arrhythmias, valvular heart disease, dyslipidemia, hypertension, stroke, diabetes, documented thrombosis, troponin, CRP, ESR, ferritin, LDH, BNP, D-dimer >5x the upper limit of normal, lactate, and right ventricular outflow tract velocity time integral <9.5 were significant. After multivariable adjustment, explanatory variables associated with the composite endpoint included troponin (OR 2.36;95% CI 1.08-5.17, p 0.03), D-dimer (OR 1.5;95% CI 1.23-1.98, p<0.01, lactate (OR 1.58;95% CI 1.28-1.95, p<0.01), and documented thrombosis (OR 3.56;95% CI 1.30-8.70, p<.05). Race was not a predictor of poor outcomes in the bivariate or multivariate analysis (Table 2). Conclusions: In a large urban cohort with a predominantly minority population, we identified several clinical predictors of poor outcomes. Of note, race was not a predictor of the primary endpoint in this study. While recent literature has demonstrated worse outcomes among racial minorities infected with SARS-CoV-2, our data suggests these variations are related to social determinants of health rather than biologic causes.

ABSTRACT

Introduction: While the global dissemination of vaccines targeting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in a decline in the incidence of infections, the case fatality rates have remained relative stable. A major objective of managing hospitalized patients with documented or suspected COVID-19 infection is the rapid identification of features associated with severe illness using readily available laboratory tests and clinical tools. The sequential organ failure assessment (SOFA) score is a validated tool to facilitate the identification of patients at risk of dying from sepsis. Purpose: The aim of this study was to assess the discriminatory accuracy of the SOFA score in predicting clinical decompensation in patients hospitalized with COVID-19 infection. Methods:We conducted a retrospective analysis at a three-hospital health system, comprised of one tertiary and two community hospitals, located in the Chicago metropolitan area. All patients had positive SARS-CoV-2 testing and were hospitalized for COVID-19 infection. The primary outcome was clinical decompensation, defined as the composite endpoint of death, ICU admission, or need for intubation. We utilized the most abnormal laboratory values observed during the admission to calculate the SOFA score. Receiver Operating Curves (ROC) were then constructed to determine the sensitivity and specificity of SOFA scores. Results: Between March 1st and May 31st 2020, 1029 patients were included in our analysis with 367 patients meeting the study endpoint. The median SOFA score was 2.0 IQR (Q1, Q3 1,4) for the entire cohort. Patients who had in-hospital mortality had a median SOFA score of 4.0 (Q1,Q3 3,7). In patients that met the primary composite endpoint, the median SOFA score was 3.0, IQR (Q1, Q3 2,6). The ROC was 0.776 (95% CI 0.746-0.806, p<0.01). Conclusion: The SOFA score demonstrates strong discriminatory accuracy for prediction of clinical decompensation in patients presenting with COVID-19 at our urban hospital system.

ABSTRACT

Purpose/Objective(s): The COVID-19 pandemic posed challenges in resource allocation and breast cancer (BC) treatment decisions. Our study aims to understand changes in practice patterns of United States radiation oncologists (RO) treating BC during the COVID-19 pandemic. Materials/Methods: An IRB-approved 58-question survey with 6 clinical scenarios was distributed between July 17 and November 8, 2020 to ASTRO directory members. The cases included 1) Low-grade ductal carcinoma in situ (DCIS), 2) Low-risk BC treated with lumpectomy, 3) Low-risk BC treated with mastectomy with reconstruction 4) BC treated with neoadjuvant chemotherapy and mastectomy with reconstruction 5) BC treated with mastectomy and adjuvant chemotherapy but without reconstruction 6) Metastatic BC with enlarging breast mass. RO were surveyed about treatment recommendations if cases were seen pre-pandemic (PP) and hypothetically during the peak of pandemic (DTPP). Chi-square and McNemar-Bowker tests were used to examine the significance of changes. Results: A total of 285 respondents from 48 states completed the survey and reported treating at least one patient with BC in the past 12 months. 45% primarily practice in university affiliated hospitals and 43% in private practice. 22% reported treating ≥ 1 COVID-positive BC patients. Moderate hypofractionation (2.31 - 3 Gy per fraction) in the PMRT and immediate reconstruction setting was recommended by 0.7% PP compared to 10.5% DTPP. In the low-risk PMRT setting, recommendation of no further treatment increased from 13% PP to 20% DTPP. Further, 56% changed their DCIS recommendations if the patient was seen DTPP. For low-risk BC, whole breast RT was preferred by 83.5% PP compared to 46.7% DTPP, and 35.1% recommended delay of RT DTPP compared to 0.4% PP (P < 0.05). Increase in ultra-hypofractionation (> 5 Gy per fraction) was significant for low-risk BC after lumpectomy as 0.4% reported its use PP compared to 3.8% DTPP. In addition, utilization of brachytherapy as PBI modality decreased from 23.9% to 17% among respondents PP and DTPP respectively. The Florence fractionation schedule for PBI was recommended by 46.2% for early-stage BC and by 51.7% for DCIS DTPP compared to 20% and 34.4% PP. Finally, 68.1% reported the use of 10-25 fractions PP for the palliative scenario. However, of those who would change their recommendation (48.8%), 62.8% reported recommendation of ≤ 5 fractions DTPP. Additional subset analysis by geographic region and practice type were notable for variable changes in treatment recommendations, and will be presented. Conclusion: This large survey of Breast RO clinical decision making demonstrates significant differences in recommendations and rapid adoption of unique fractionation. While likely reflective of intent to optimize resource allocations during the pandemic, maintenance of new practice patterns remains subject to future investigation.

ABSTRACT

Introduction Video consultation involves the live interaction between the doctor and the patient remotely. Prior to the Covid-19 pandemic, the majority of video consultations in primary care were provided by GPs who were not the individual’s own GP, which presented safety and continuity issues. This study aims to determine GPs’ attitudes to the use of video consultation for their own patients. Methods This was a qualitative study involving semi-structured interviews. Participants were purposively recruited through use of a GP tutor as a key informant and guided by a sampling framework to include those with and without previous video consultation experience. Braun and Clarke thematic analysis was used. Results Participants included eight GPs, half of whom had previously worked with video consultation. Four themes emerged: Impact on the consultation, the potential role, and the potential threat to current practice and technology and logistics. There were optimistic and cautious observations within all themes. Conclusion With the increased use of video consultation, Irish General Practice is in a unique position to frame the future its use. The provision of this modality to one’s own patients may provide benefit while mitigating some of the pitfalls but would not entirely avoid the potential dangers of video consultation. © 2021, Irish Medical Association.

ABSTRACT

Objective: To describe a case of a critically ill patient with acute refractory respiratory failure and ARDS managed via a commonly used social media site (WhatsApp) between an International center with ECLS capability and a well-experienced ECLS center-based thousands of miles away in the United States. Methods: A case report. Covid19, a pandemic declared by WHO, ushered in innovation and new technologies, such as video patient conference calls, telemedicine appointments. The impact of social media has also played a considerable role in linking clinicians globally with using platforms such as Zoom or Microsoft Teams to enhance patient care and management. Results: A 41 yr male was admitted to a tertiary hospital in Hyderabad, India, with worsening acute hypoxic respiratory failure, ARDS secondary to influenza pneumonia amidst a devastating pandemic(tested negative for SARS-CoV-2 infection). Tertiary hospital in Hyderabad, being an ECLS capable center but limited by experience in long-term venovenous ECMO management, sought assistance from Allegheny General Hospital, Pittsburgh PA, via a professional media platform LinkedIn. A WhatsApp group was created. The two centers dynamically exchanged 24/7 basis protocols on analgo-sedation, anticoagulation, and veno-venous ECMO weaning, including the critically ill patient's daily care goals. The fruits of 21 days of aggressive VV ECMO support, consideration for an early tracheostomy resulted in a successful trial off ECLS and active pulmonary -physical rehabilitation care placement. The patient returned to the community with an improved physical and mental condition. Conclusions: We describe a unique International collaboration between an ECMO capable center with less experience in managing ECMO and a large ELSO certified center of excellence via a social media platform in the successful outcomes of a critically ill patient ARDS supported by veno venous ECMO. Issues of patient confidentiality and liability, linking of resources are areas of ongoing needed conversation.

ABSTRACT

Objective: Post COVID-19, healthcare professionals (HCPs) have had to adapt to an increasingly digitally focused world to communicate and educate. We investigated the challenges that US HCPs face in staying up to date with online content, how they use digital platforms, and their opinion of digital online leaders (DOLs) in healthcare. Research design and methods: A 12-question web-based Survey Monkey questionnaire was developed and circulated to a targeted HCP audience across the USA. All responses were anonymous. Results: From 9 to 10 December 2020, 134 surveys were completed by HCPs (including carers, nurses and doctors) in the USA across a wide variety of specialties (predominantly mental health, emergency medicine and surgery). Of these, 71% were aged between 25 and 55 years;all US regions were represented. Only 6% of respondents said they never reviewed digital content. Overall, 37% of respondents felt that they had insufficient time to review online news and research updates, 35% felt that they had difficulty knowing which online sources to trust, and 29% felt content was too biased/promotional. Overall, 63% used HCP networking platforms, the most used being Mayo Clinic Social Media Network (26%), Doximity (17%) and Sermo (9%). The benefits of DOLs in healthcare included: providing quick access to content (49%), directing HCPs to further information (48%), and providing an educational community (39%). Conclusions: In this survey of HCPs, lack of time and trust in content sources are issues when using social media and HCP networking platforms. DOLs contribute to educational communities and provide HCPs with the peer-to-peer support that they lack in this COVID-19 era.
