Soft Skills: The Work of Communication and Persuasion Among Nurse Navigators in Hospital at Home Programs.

OBJECTIVE: To assess the role of soft skills in the work of Hospital at Home (HaH) nurse navigators. BACKGROUND: In HaH programs that employ them, nurse navigators are often responsible for identifying, assessing, referring, and educating potential HaH patients. The experiences of these navigators have gone understudied. METHODS: Researchers conducted semistructured interviews and observations with nurse navigators (n = 7) who collectively cover 14 North Carolina-based HaH sites. Navigators were asked to keep diaries of responses to directed questions. RESULTS: In their capacity as navigators, interviewees said they served several roles: intermediaries between hospital and HaH staff, interpreters of clinical knowledge for patients, and champions of, and educators for, the home-based program. The navigators noted that the interpersonal soft skills of building rapport, clear communication, and gentle persuasion were of the utmost importance in this work. CONCLUSIONS: The job descriptions of nurse navigators in HaH programs should fully reflect the breadth of their responsibilities, including time performing soft skilled labor. Also, training for these roles should include techniques to develop and refine these skills.

Tracking SARS-CoV-2 Omicron lineages using real-time reverse transcriptase PCR assays and prospective comparison with genome sequencing.

Omicron has become the dominant SARS-CoV-2 variant globally since December 2021, with distinct waves being associated with separate Omicron sublineages. Rapid detection of BA.1, BA.2, BA.4, and BA.5 was accomplished in the province of Alberta, Canada, through the design and implementation of real-time reverse transcriptase PCR assays targeting S:N501Y, S:ins214EPE, S:H69/V70, ORF7b:L11F, and M:D3N. Using the combination of results for each of these markers, samples could be designated as belonging to sublineages within BA.1, BA.2, BA.4, or BA.5. The analytical sensitivity of these markers ranged from 132 to 2229 copies/mL and in-laboratory accuracy was 98.9-100%. A 97.3% agreement using 12,592 specimens was demonstrated for the assays compared to genome sequencing. The use of these assays, combined with genome sequencing, facilitated the surveillance of SARS-CoV-2 lineages throughout a BA.5-dominated period.

Respiratory virus coinfections with severe acute respiratory coronavirus virus 2 (SARS-CoV-2) continue to be rare one year into the coronavirus disease 2019 (COVID-19) pandemic in Alberta, Canada (June 2020-May 2021).

To assess the burden of respiratory virus coinfections with severe acute respiratory coronavirus virus 2 (SARS-CoV-2), this study reviewed 4,818 specimens positive for SARS-CoV-2 and tested using respiratory virus multiplex testing. Coinfections with SARS-CoV-2 were uncommon (2.8%), with enterovirus or rhinovirus as the most prevalent target (88.1%). Respiratory virus coinfection with SARS-CoV-2 remains low 1 year into the coronavirus disease 2019 (COVID-19) pandemic.

Evaluating Racial/Ethnic Differences in Care Escalation Among COVID-19 Patients in a Home-Based Hospital.

The novel coronavirus disease 2019 (COVID-19) has infected over 414 million people worldwide with 5.8 million deaths, as of February 2022. Telemedicine-based interventions to expand healthcare systems' capacity and reduce infection risk have rapidly increased during the pandemic, despite concerns regarding equitable access. Atrium Health Hospital at Home (AH-HaH) is a home-based program that provides advanced, hospital-level medical care and monitoring for patients who would otherwise be hospitalized in a traditional setting. Our retrospective cohort study of positive COVID-19 patients who were admitted to AH-HaH aims to investigate whether the rate of care escalation from AH-HaH to traditional hospitalization differed based on patients' racial/ethnic backgrounds. Logistic regression was used to examine the association between care escalation within 14 days from index AH-HaH admission and race/ethnicity. We found approximately one in five patients receiving care for COVID-19 in AH-HaH required care escalation within 14 days. Odds of care escalation were not significantly different for Hispanic or non-Hispanic Blacks compared to non-Hispanic Whites. However, secondary analyses showed that both Hispanic and non-Hispanic Black patients were younger and with fewer comorbidities than non-Hispanic Whites. The study highlights the need for new care models to vigilantly monitor for disparities, so that timely and tailored adaptations can be implemented for vulnerable populations.

Nucleus of the solitary tract A2 neurons control feeding behaviors via projections to the paraventricular hypothalamus.

Hindbrain NTS neurons are highly attuned to internal physiological and external environmental factors that contribute to the control of food intake but the relevant neural phenotypes and pathways remain elusive. Here, we investigated the role of NTS A2 neurons and their projections in the control of feeding behaviors. In male TH Cre rats, we first confirmed selective targeting of NTS A2 neurons and showed that chemogenetic stimulation of these neurons significantly suppressed dark cycle food intake, deprivation re-feed and high fat diet intake. Despite reducing intake, activation of NTS A2 neurons had no effect on food approach, anxiety-like behaviors, locomotor activity, blood glucose levels nor did it induce nausea/malaise, thus revealing a selective role for these neurons in the consummatory aspect of food intake control. Pathway-specific mapping and manipulation of NTS A2 neurons showed that these effects were mediated by NTS A2 neurons projecting to the paraventricular nucleus of the hypothalamus (PVH) because chemogenetic activation of these projections, but not projections to bed nucleus of the stria terminalis (BNST), reduced food intake. Cell-type specific analyses demonstrated that activation of NTS A2 neurons recruited both PVH oxytocin (OT)- and corticotropin-releasing factor (CRF)-expressing neurons, and plasma analyses showed increased plasma corticosterone following NTS A2 stimulation. While we also showed that chemogenetic inhibition of NTS A2 neurons attenuated the intake inhibitory effects of CCK, the specificity of transgene expression was low. Together, these findings showed that NTS A2 neurons are sufficient to control the consummatory aspects of feeding, regardless of energy status or food palatability and identified their projections to PVH, but not BNST, in food intake control.

[18F]-(2S,4R)4-Fluoroglutamine PET Imaging of Glutamine Metabolism in Murine Models of Hepatocellular Carcinoma (HCC).

Purpose: Quantitative in vivo [18F]-(2S,4R)4-fluoroglutamine ([18F]4-FGln or more simply [18F]FGln) metabolic kinetic parameters are compared with activity levels of glutamine metabolism in different types of hepatocellular carcinoma (HCC). Methods: For this study, we used two transgenic mouse models of HCC induced by protooncogenes, MYC, and MET. Biochemical data have shown that tumors induced by MYC have increased levels of glutamine metabolism compared to those induced by MET. One-hour dynamic [18F]FGln PET data were acquired and reconstructed for fasted MYC mice (n = 11 tumors from 7 animals), fasted MET mice (n = 8 tumors from 6 animals), fasted FVBN controls (n = 8 normal liver regions from 6 animals), nonfasted MYC mice (n = 16 tumors from 6 animals), and nonfasted FVBN controls (n = 8 normal liver regions from 3 animals). The influx rate constants (K 1) using the one-tissue compartment model were derived for each tumor with the left ventricular blood pool input function. Results: Influx rate constants were significantly higher for MYC tumors (K 1 = 0.374 ± 0.133) than for MET tumors (K 1 = 0.141 ± 0.058) under fasting conditions (P = 0.0002). Rate constants were also significantly lower for MET tumors (K 1 = 0.141 ± 0.135) than normal livers (K 1 = 0.332 ± 0.179) under fasting conditions (P = 0.0123). Fasting conditions tested for MYC tumors and normal livers did not result in any significant difference with P values > 0.005. Conclusion: Higher influx rate constants corresponded to elevated levels of glutamine metabolism as determined by biochemical assays. The data showed that there is a distinctive difference in glutamine metabolism between MYC and MET tumors. Our study has demonstrated the potential of [18F]FGln PET imaging as a tool to assess glutamine metabolism in HCC tumors in vivo with a caution that it may not be able to clearly distinguish HCC tumors from normal liver tissue.

Evolving strategy for an evolving virus: Development of real-time PCR assays for detecting all SARS-CoV-2 variants of concern.

In order to detect the SARS-CoV-2 variants of concern (VOCs), five real-time reverse transcriptase PCR (rRT-PCR) assays were designed to target the critical discriminatory mutations responsible for the following amino acid changes in the spike protein: two Δ69-70 + N501Y + E gene triplexes (one optimized for Alpha [B.1.1.7] and one optimized for Omicron [B.1.1.529]), a K417N + 242-244 wild-type duplex, a K417T + E484K duplex, and a L452R + P681 + E484Q triplex. Depending on the assay, sensitivity was 98.97-100% for the detection of known VOC-positive samples, specificity was 97.2-100%, limit of detection was 2-116 copies/reaction, intra- and interassay variability was less than 5%, and no cross-reactivity with common respiratory pathogens was observed with any assay. A subset of rRT-PCR- positive VOC samples were further characterized by genome sequencing. A comparison of the lineage designation by the VOC rRT-PCR assays and genome sequencing for the detection of the Alpha, Beta, Gamma, Delta and Omicron variants showed clinical sensitivities of 99.97-100 %, clinical specificities of 99.6-100 %, positive predictive values of 99.8-100%, and negative predictive values of 99.98-100 %. We have implemented these rRT-PCR assays targeting discriminatory single nucleotide polymorphisms for ongoing VOC screening of SARS-CoV-2 positive samples for surveillance purposes. This has proven extremely useful in providing close to real-time molecular surveillance to monitor the emergence of Alpha, the replacement of Alpha by Delta, and the replacement of Delta by Omicron. While the design, validation and implementation of the variant specific PCR targets is an ever-evolving approach, we find the turn-around-time, high throughput and sensitivity to be a useful complementary approach for SARS-CoV-2 genome sequencing for surveillance purposes in the province of Alberta, Canada.

A Case of Gastric Outlet Obstruction Secondary to Parastomal Stomach Herniation.

Parastomal hernia (PH) is an abnormal herniation of tissue or intra-abdominal organ through the fascial defect created at the ostomy site. It is a common complication of stoma creation and usually contains bowel, intra-abdominal fat, or omentum. Herniation of a fixed organ like the stomach is very rare and can lead to significant morbidity and mortality. Here, we present a case of an 83-year-old female with a history of sigmoidectomy and subsequent development of parastomal hernia who presented with abdominal pain, nausea, and vomiting and was found to have stomach herniation into the parastomal hernia sac. She was managed conservatively with intravenous (IV) fluids, electrolyte replacement, and decompression with a nasogastric (NG) tube. In this article, we have discussed the incidence, clinical presentation, diagnosis, and management of gastric involvement in the parastomal hernia that can help clinicians identify and treat it early at the time of presentation.

A Case of Heterotopic Gastric Tissue in Duodenal Bulb: An Interesting Endoscopic Finding.

Gastric heterotopia (GH) is a rare, congenital condition where gastric tissue is found outside of its normal location in the gastric mucosa. It is usually benign and can be found throughout the gastrointestinal (GI) tract. In the duodenum, it is usually seen as multiple polyps, specifically in the duodenal bulb. Here, we discuss the case of a 67-year-old male patient who presented with hematemesis, melena, and abdominal pain. Esophagogastroduodenoscopy (EGD) and biopsy revealed a mass consisting of heterotopic gastric mucosa along with an esophageal ulcer. In this article, we will discuss the literature related to the clinical presentation, diagnosis, and management of GH.

Selective Androgen Receptor Modulator Induced Hepatotoxicity.

Selective androgen receptor modulators (SARMs) have been developed as an alternate to traditional anabolic steroids due to their favorable effects on the bones and muscles without androgenic side effects. They are very popular among athletes and bodybuilders and are available online or over the counter. The FDA has warned of their side effects including liver injury. Here we present the case of a 29-year-old patient who presented with jaundice, fatigue, and elevated liver function tests after starting SARM supplements. His symptoms improved and eventually resolved with stopping the supplements. The purpose of this case report is to raise awareness and educate clinicians of the potential side effect of hepatotoxicity of these supplements that can help in its early identification and management.

Effect of a Multicomponent Sepsis Transition and Recovery Program on Mortality and Readmissions After Sepsis: The Improving Morbidity During Post-Acute Care Transitions for Sepsis Randomized Clinical Trial.

OBJECTIVES: To evaluate whether a nurse navigator-led, multicomponent Sepsis Transition And Recovery program improves 30-day mortality and readmission outcomes after sepsis hospitalization. DESIG: n: Multisite pragmatic randomized clinical trial. SETTING: Three hospitals in North Carolina from January 2019 to March 2020. PATIENTS: Eligible patients hospitalized for suspected sepsis and deemed high-risk for mortality or readmission by validated internal risk models. INTERVENTIONS: Patients were randomized to receive usual care alone (i.e., routine transition support, outpatient care; n = 342) or additional Sepsis Transition And Recovery support (n = 349). The 30-day intervention involved a multicomponent transition service led by a nurse navigator through telephone and electronic health record communication to facilitate best practice postsepsis care strategies during and after hospitalization including: postdischarge medication review, evaluation for new impairments or symptoms, monitoring comorbidities, and palliative care approach when appropriate. Clinical oversight was provided by a Hospital Medicine Transition Services team. MEASUREMENTS AND MAIN RESULTS: The primary outcome was a composite of mortality or hospital readmission at 30 days. Logistic regression models were constructed to evaluate marginal and conditional odds ratios (adjusted for prognostic covariates: age, comorbidity, and organ dysfunction at enrollment). Among 691 randomized patients (mean age = 63.7 ± 15.1 yr; 52% female), a lower percentage of patients in the Sepsis Transition And Recovery group experienced the primary outcome compared with the usual care group (28.7% vs 33.3%; risk difference, 4.7%; odds ratio, 0.80; 95% CI, 0.58-1.11; adjusted odds ratio, 0.80; 95% CI, 0.64-0.98). There were 74 deaths (Sepsis Transition And Recovery: 33 [9.5%] vs usual care: 41 [12.0%]) and 155 rehospitalizations (Sepsis Transition And Recovery: 71 [20.3%] vs usual care: 84 [24.6%]). CONCLUSIONS: In a multisite randomized clinical trial of patients hospitalized with sepsis, patients provided with a 30-day program using a nurse navigator to provide best practices for postsepsis care experienced a lower proportion of either mortality or rehospitalization within 30 days after discharge. Further research is needed to understand the contextual factors associated with successful implementation.

Implementation of Drive-Through Testing for COVID-19 With Community Paramedics.

OBJECTIVE: In this manuscript, we discuss the implementation and deployment of mobile integrated health and community paramedicine (MIH/CP) testing sites to provide screening, testing, and community outreach during the first months of the 2019 coronavirus disease (COVID-19) pandemic in the metropolitan region of Charlotte, North Carolina. This program addresses the need for an agile testing strategy during the current pandemic. We disclose the number of patients evaluated as "persons under investigation" and the proportion with positive severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) results from these sites. We describe how the programs were applied to patient care and include considerations on how additional staffing, scalability, and flexibility of these services may be applied to future patient and health care crises. METHODS: This is a descriptive report of the implementation of MIH/CP test sites in our health care system's early response to the COVID-19 pandemic in March 2020. Retrospective data on the number of patients and their associated demographics are reported here as raw data. No statistical analysis was performed. RESULTS: Between March 15, 2020, and April 15, 2020, our 6 MIH/CP test sites evaluated 4342 patients. Of these, 401 patients (9.2%) had positive test results, 62.8% of whom were women. The estimated duration of each patient encounter under investigation was 3 to 5 minutes. The paramedics were able to perform a brief history, specific physical examination, and screening for signs of hypoxemic respiratory failure. There were no cases of accidental exposure or failure of personal protective equipment for the MIH/CP paramedics. CONCLUSIONS: In our health care system, we pivoted the traditional MIH/CP model to rapidly initiate remote drive-through testing for COVID-19 in pre-screened individuals. This model allowed us to test patients with suspected COVID-19 patients away from traditional health care sites and mitigate exposure to health care workers and other patients.

Factors associated with COVID-19 vaccine hesitancy amongst refugees in Australia.

Background: Refugees may be especially vulnerable to the adverse effects of COVID-19. Therefore it is critical that refugee communities are supported to access COVID-19 vaccines and for public health responses to address vaccine hesitancy. Objective: To investigate the key demographic factors, barriers and attitudes associated with vaccine hesitancy in a community sample of refugees. Method: Participants in the Refugee Adjustment Study, a cohort of refugees living in Australia, were invited to complete a survey about their COVID-19 vaccine intentions, barriers to access and attitudes relating to the vaccine. Results: Of the 516 participants, 88% were unvaccinated and 28.1% were classed as vaccine hesitant. Key predictors of vaccine hesitancy were younger age, information and trust barriers, lower logistical barriers, and attitudes relating to low control and risk posed by COVID-19. Conclusions: Findings suggest that public health strategies need to address trust, control and risk perception attitudes to increase COVID-19 vaccine uptake in resettled refugee communities.

Antecedentes: Los refugiados pueden ser especialmente vulnerables a los efectos adversos del COVID-19. Por lo tanto, es fundamental que las comunidades de refugiados reciban apoyo para acceder a las vacunas COVID-19 y para que las respuestas de salud pública aborden la indecisión ante las vacunas.Objetivo: Investigar los factores demográficos clave, las barreras y las actitudes asociadas con la indecisión ante las vacunas en una muestra comunitaria de refugiados.Método: Se invitó a los participantes en el Estudio de Adaptación de Refugiados, una cohorte de refugiados que viven en Australia, a completar una encuesta sobre sus intenciones de vacunarse contra el COVID-19, barreras de acceso y actitudes relacionadas con la vacuna.Resultados: De los 516 participantes, el 88% no estaban vacunados y el 28,1% se clasificaron como reacios a vacunarse. Los predictores clave de la vacilación a la vacuna fueron menor edad, las barreras en información y confianza, menores barreras logísticas y las actitudes relacionadas con bajo control y el riesgo que plantea el COVID-19.Conclusiones: Los hallazgos sugieren que las estrategias de salud pública deben abordar las actitudes de confianza, control y percepción del riesgo para aumentar la aceptación de la vacuna COVID-19 en las comunidades de refugiados reasentados.

Reducing Severe Tracheal Intubation Events Through an Individualized Airway Bundle.

BACKGROUND: Neonatal tracheal intubation (TI) is a high-risk procedure associated with adverse safety events. In our newborn and infant ICU, we measure adverse tracheal intubation-associated events (TIAEs) as part of our participation in National Emergency Airway Registry for Neonates, a neonatal airway registry. We aimed to decrease overall TIAEs by 10% in 12 months. METHODS: A quality improvement team developed an individualized approach to intubation using an Airway Bundle (AB) for patients at risk for TI. Plan-do-study-act cycles included AB creation, simulation, unit roll out, interprofessional education, team competitions, and adjusting AB location. Outcome measure was monthly rate of TIAEs (overall and severe). Process measures were AB initiation, AB use at intubation, video laryngoscope (VL) use, and paralytic use. Balancing measure was inadvertent administration of TI premedication. We used statistical process control charts. RESULTS: Data collection from November 2016 to August 2020 included 1182 intubations. Monthly intubations ranged from 12 to 41. Initial overall TIAE rate was 0.093 per intubation encounter, increased to 0.172, and then decreased to 0.089. System stability improved over time. Severe TIAE rate decreased from 0.047 to 0.016 in June 2019. AB initiation improved from 70% to 90%, and AB use at intubation improved from 18% to 55%. VL use improved from 86% to 97%. Paralytic use was 83% and did not change. The balancing measure of inadvertent TI medication administration occurred once. CONCLUSIONS: We demonstrated a significant decrease in the rate of severe TIAEs through the implementation of an AB. Next steps include increasing use of AB at intubation.

The association between COVID-19 related stressors and mental health in refugees living in Australia.

BACKGROUND: Refugees may be particularly vulnerable to the adverse effects of the COVID-19 pandemic on mental health due to their traumatic pasts and the challenges of the postmigration environment. OBJECTIVE: To evaluate the prevalence of COVID-19 related stressors and their relationship to key mental health and functioning outcomes in a resettled refugee sample. METHOD: N = 656 refugees and asylum seekers living in Australia completed a survey in June 2020 to index their mental health (posttraumatic stress disorder (PTSD), depression, health anxiety and disability) and COVID-19 experiences. The relationship between COVID-19 stressors and mental health was examined using a series of hierarchical linear regression models while controlling for other key demographic factors. RESULTS: Refugees' most prevalent stressors related to worries of being infected by COVID-19 or the risk COVID-19 posed to others, which predicted health anxiety and PTSD. Social-related difficulties predicted depression and disability symptoms. Accessing and trusting information from authorities were the least prevalent stressors and were not significantly associated with mental health outcomes; neither was accessing basic supplies and financial support. Fears relating to the future such as concerns about visa application processes predicted health anxiety and disability. Crucially, the strongest predictor of all mental health outcomes was COVID-19 serving as a reminder of difficult past events. CONCLUSIONS: Refugees may be uniquely affected by COVID-19 because the pandemic serves as a reminder of their past conflict and persecution trauma. It is critical that mental health strategies accommodate the specific needs of refugees during the COVID-19 pandemic.

Antecedentes: Los refugiados pueden ser particularmente vulnerables a los efectos adversos de la pandemia del COVID-19 en la salud mental a consecuencia de sus pasados traumáticos y los desafíos del ambiente post migración.Objetivo: Evaluar la prevalencia de los estresores relacionados al COVID-19 y su relación a resultados claves funcionamiento y salud mental claves en una muestra de refugiados reubicados.Método: N = 656 refugiados y personas en búsqueda de asilo que viven en Australia completaron una encuesta en junio de 2020 para identificar su salud mental (trastorno de estrés postraumático (TEPT), depresión, ansiedad de salud y discapacidad) y las experiencias de COVID-19. Fueron examinadas la relación entre los estresores de COVID-19 y la salud mental usando una serie de modelos de regresión lineal jerárquica mientras se controlaron otros factores demográficos claves.Resultados: Los estresores más prevalentes de los refugiados se relacionaban con la preocupación de infectarse de COVID-19 o el riesgo del COVID-19 hacia otros, lo cual predijo la ansiedad de salud y TEPT. Las dificultades sociales predijeron los síntomas de depresión y discapacidad. Acceder y confiar en la información proporcionada por las autoridades fueron los estresores menos prevalentes y no se asociaron significativamente a los resultados de salud mental; tampoco lo fue el acceder a insumos básicos y apoyo financiero. Los temores asociados al futuro tales como preocupaciones sobre los procesos de aplicación a la visa predijeron la ansiedad de salud y discapacidad. De manera crucial, el predictor más fuerte de todos los resultados de salud mental fue el COVID-19 sirviendo como un recordatorio de los eventos pasados difíciles.Conclusiones: Los refugiados pueden estar afectados de forma única por el COVID-19 porque la pandemia sirve como un recordatorio de sus conflictos pasados y trauma de persecución. Es crítico que las estrategias de salud mental se acomoden a las necesidades específicas de los refugiados durante la pandemia del COVID-19.

Precision Response to the Rise of the SARS-CoV-2 B.1.1.7 Variant of Concern by Combining Novel PCR Assays and Genome Sequencing for Rapid Variant Detection and Surveillance.

SARS-CoV-2 variants of concern (VOCs) have emerged as a global threat to the COVID-19 pandemic response. We implemented a combined approach to quickly detect known VOCs while continuously monitoring for evolving mutations of the virus. To rapidly detect VOCs, two real-time reverse transcriptase PCR assays were designed and implemented, targeting the spike gene H69/V70 deletion and the N501Y mutation. The H69/V70 deletion and N501Y mutation assays demonstrated accuracies of 98.3% (95% CI 93.8 to 99.8) and 100% (95% CI 96.8 to 100), limits of detection of 1,089 and 294 copies/ml, and percent coefficients of variation of 0.08 to 1.16% and 0 to 2.72% for the two gene targets, respectively. No cross-reactivity with common respiratory pathogens was observed with either assay. Implementation of these tests allowed the swift escalation in testing for VOCs from 2.2% to ∼100% of all SARS-CoV-2-positive samples over 12 January to 9 February 2021, and resulted in the detection of a rapid rise of B.1.1.7 cases within the province of Alberta, Canada. A prospective comparison of the VOC assays to genome sequencing for the detection of B.1.1.7, combined detection of P.1 and B.1.351, and wild-type (i.e., non-VOC) lineages showed sensitivities of 98.2 to 100%, specificities of 98.9 to 100%, positive predictive values of 76.9% to 100%, and negative predictive values of 96 to 100%. Variant screening results inform sampling strategies for regular surveillance by genome sequencing, thus allowing rapid identification of known VOCs while continuously monitoring the evolution of SARS-CoV-2 in the province. IMPORTANCE Different strains, or variants, of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, the virus that causes COVID-19) have emerged that have higher levels of transmission, less susceptibility to our immune response, and possibly cause more severe disease than previous strains of the virus. Rapid detection of these variants of concern is important to help contain them and prevent them from spreading widely within the population. This study describes two newly developed tests that are able to identify and differentiate the variants of concern from regular strains of SARS-CoV-2. These tests are faster and simpler than the main, gold standard method of identifying variants of concern (genome sequencing). These tests also demonstrated a high correlation with genome sequencing and allowed for the rapid and accurate detection of the rise of B.1.1.7 (one of the variants of concern) in the province of Alberta, Canada.

Protocol for a two-arm pragmatic stepped-wedge hybrid effectiveness-implementation trial evaluating Engagement and Collaborative Management to Proactively Advance Sepsis Survivorship (ENCOMPASS).

BACKGROUND: Sepsis survivors experience high morbidity and mortality, and healthcare systems lack effective strategies to address patient needs after hospital discharge. The Sepsis Transition and Recovery (STAR) program is a navigator-led, telehealth-based multicomponent strategy to provide proactive care coordination and monitoring of high-risk patients using evidence-driven, post-sepsis care tasks. The purpose of this study is to evaluate the effectiveness of STAR to improve outcomes for sepsis patients and to examine contextual factors that influence STAR implementation. METHODS: This study uses a hybrid type I effectiveness-implementation design to concurrently test clinical effectiveness and gather implementation data. The effectiveness evaluation is a two-arm, pragmatic, stepped-wedge cluster randomized controlled trial at eight hospitals in North Carolina comparing clinical outcomes between sepsis survivors who receive Usual Care versus care delivered through STAR. Each hospital begins in a Usual Care control phase and transitions to STAR in a randomly assigned sequence (one every 4 months). During months that a hospital is allocated to Usual Care, all eligible patients will receive usual care. Once a hospital transitions to STAR, all eligible patients will receive STAR during their hospitalization and extending through 90 days from discharge. STAR includes centrally located nurse navigators using telephonic counseling and electronic health record-based support to facilitate best-practice post-sepsis care strategies including post-discharge review of medications, evaluation for new impairments or symptoms, monitoring existing comorbidities, and palliative care referral when appropriate. Adults admitted with suspected sepsis, defined by clinical criteria for infection and organ failure, are included. Planned enrollment is 4032 patients during a 36-month period. The primary effectiveness outcome is the composite of all-cause hospital readmission or mortality within 90 days of discharge. A mixed-methods implementation evaluation will be conducted before, during, and after STAR implementation. DISCUSSION: This pragmatic evaluation will test the effectiveness of STAR to reduce combined hospital readmissions and mortality, while identifying key implementation factors. Results will provide practical information to advance understanding of how to integrate post-sepsis management across care settings and facilitate implementation, dissemination, and sustained utilization of best-practice post-sepsis management strategies in other heterogeneous healthcare delivery systems.
