A Collaborative Emergency Medicine and Radiology Pulmonary Nodule Program: Identification of Associated Efficacy and Outcomes.

PURPOSE: Incidental radiologic findings are commonplace, but the episodic nature of emergency department (ED) care makes it challenging to ensure that patients obtain appropriate follow-up. Rates of follow-up range from 30% to 77%, with some studies demonstrating that more than 30% have no follow-up at all. The aim of this study is to describe and analyze the outcomes of a collaborative emergency medicine and radiology initiative to establish a formal workflow for the follow-up of pulmonary nodules identified during ED care. METHODS: A retrospective analysis was performed of patients referred to the pulmonary nodule program (PNP). Patients were divided into two categories: those with follow-up and those who do not have post-ED follow-up. The primary outcome was determining follow-up rates and outcomes, including patients referred for biopsy. The characteristics of patients who completed follow-up compared with those lost to follow-up were also examined. RESULTS: A total of 574 patients were referred to the PNP. Initial follow-up was established in 390 (69.1%); 30.8% were considered lost to follow-up, and more than half of these patients did not respond to initial contact. There were minimal differences in characteristics between patients in these two categories. Of the 259 patients who completed PNP follow-up, 26 were referred for biopsy (13%). CONCLUSIONS: The PNP provided effective transitions of care and potentially improved patient health care. Strategies to further enhance follow-up adherence will provide iterative improvement of the program. The PNP provides an implementation framework for post-ED pulmonary nodule follow-up in other health care systems and can be modified for use with other incidental diagnostic findings.

Emergency Department Patient Navigator Program Demonstrates Reduction in Emergency Department Return Visits and Increase in Follow-up Appointment Adherence.

BACKGROUND: An estimated 56% of emergency department (ED) visits are avoidable. One motivation for return visits is patients' perception of poor access to timely outpatient care. Efforts to facilitate access may help reduce preventable ED visits. We aimed to analyze whether an ED patient navigator (PN) program improved adherence with outpatient appointments and reduced ED return visits. METHODS: We performed a retrospective analysis of patients evaluated and discharged from two EDs from October 2016 to December 2019. Using propensity score matching, an intervention case group was matched against two control groups - patients similar to the case group who presented either (1) pre-PN intervention or (2) post-PN intervention and did not receive intervention. The four outcomes included 72-h return ED visits, 30-day return ED visits, overall ED utilization, as well as the intervention group's adherence rates to PN-scheduled outpatient appointments. From 482,896 charts, propensity matching led to a total of 14,295 patients in each group. RESULTS: PN intervention decreased both acute and subacute ED return visits. Compared to both pre-PN and post-PN controls, navigated patients had a decrease in 72-h and 30-day return visits from 2% to 1% and 7% to 4% (p < 0.001) respectively. Navigated patients also had outpatient appointment adherence rates of 74-80% compared to the estimated national average of 25-56%. While there was no difference in mean ED utilization between the intervention group and pre-PN control group, mean ED utilization was found to be higher in the intervention group compared to the post-PN control group with 0.62 visits compared to 0.38 mean visits (p < 0.001). CONCLUSIONS: By facilitating access to post-ED care, PNs may reduce avoidable ED utilization and improve outpatient follow-up adherence. While overall ED utilization did not change, this may be due to the overall vulnerability of the navigated group which is the goal PN intervention group.

An International Virtual Classroom: The Emergency Department Experience at Weill Cornell Medicine and Weill Bugando Medical Center in Tanzania.

Emergency medicine (EM) is rapidly being recognized as a specialty around the globe. This has particular promise for low- and middle-income countries (LMICs) that experience the largest burden of disease for emergency conditions. Specialty education and training in EM remain essentially an apprenticeship model. Finding the required expertise to educate graduate learners can be challenging in regions where there are low densities of specialty providers.We describe an initiative to implement a sustainable, bidirectional partnership between the Emergency Medicine Departments of Weill Cornell Medicine (WCM) in New York, NY, USA, and Bugando Medical Center (BMC) in Mwanza, Tanzania. We used synchronous and asynchronous telecommunication technology to enhance an ongoing emergency medicine education collaboration.The Internet infrastructure for this collaboration was created by bolstering 4G services available in Mwanza, Tanzania. By maximizing the 4G signal, sufficient bandwidth could be created to allow for live 2-way audio/video communication. Using synchronous and asynchronous applications such as Zoom and WhatsApp, providers at WCM and BMC can attend real-time didactic lectures, participate in discussion forums on clinical topics, and collaborate on the development of clinical protocols. Proof of concept exercises demonstrated that this system can be used for real-time mentoring in EKG interpretation and ultrasound technique, for example. This system was also used to share information and develop operations flows during the COVID-19 pandemic. The use of telecommunication technology and e-learning in a format that promotes long-term, sustainable interaction is practical and innovative, provides benefit to all partners, and should be considered as a mechanism by which global partnerships can assist with training in emergency medicine in LMICs.

Preparedness and response at long-term care facilities following Hurricane Sandy: A qualitative analysis of experiences and attitudes among staff and administrators.

BACKGROUND: In late 2012, Hurricane Sandy struck the eastern United States. Healthcare infrastructure in New York City-including long-term care facilities (LTCFs)-was affected significantly. The authors examined the impact of the storm on LTCFs 2 years after the event, using a qualitative approach consisting of a semistructured interview focused on preparedness and response. Important insights regarding preparedness and response may be lost by quantitative analysis or outcome measurement alone. During Sandy, individuals at LTCFs experienced the event in important subjective ways that, in aggregate, could lead to valuable insights about how facilities might mitigate future risks. The authors used data from a semistructured interview to generate hypotheses regarding the preparation and response of LTCFs. The interview tool was designed to help develop theories to explain why LTCF staff and administrators experienced the event in the way they did, and to use that data to inform future policy and research. METHODS: Representatives from LTCFs located in a heavily affected area of New York City were approached for participation in a semistructured interview. Interviews were digitally recorded and transcribed. Recurrent themes were coded based on time period (before, during, or after the storm) and content. A grounded theory approach was used to identify important themes related to the participants' experiences. RESULTS: A total of 21 interviews were conducted. Several overarching themes were identified, including a perception that facilities had not prepared for an event of such magnitude, of inefficient communication and logistics during evacuation, and of lack of easily identifiable or appropriate resources after the event. Access to electrical power emerged as a key identifier of recovery for most facilities. The experience had a substantial psychological impact on LTCF staff regardless of whether they evacuated or sheltered in place during the storm. CONCLUSION: Representatives from LTCFs affected by Sandy experienced the preparation, response, and recovery phases of the event with a unique perspective. Their insights offer evidence which can be used to generate testable hypothesis regarding similar events in the future, and can inform policy makers and facility administrators alike as they prepare for extreme weather events in similar settings. Results specifically suggest that LTCFs develop plans which carefully address the unique qualities of extreme weather events, including communication with local officials, evacuation and transfer needs in geographic areas with multiple facilities, and plans for the safe transfer of residents. Emergency managers at LTCFs should consider electrical power needs with the understanding that in extreme weather events, power failures can be more protracted than in other types of emergencies.

Novel Use of Telepalliative Care in a New York City Emergency Department During the COVID-19 Pandemic.

BACKGROUND: Coronavirus-2 (COVID-19) is a global pandemic. As of August 21, mortality from COVID-19 has reached almost 200,000 people, with the United States leading the globe in levels of morbidity and mortality. Large volumes of high-acuity patients, particularly those of advanced age and with chronic comorbidities, have significantly increased the need for palliative care resources beyond usual capacity. More specifically, COVID-19 has changed the way we approach patient and family member interactions. DISCUSSION: Concern for nosocomial spread of this infection has resulted in strict visitation restrictions that have left many patients to face this illness, make difficult decisions, and even die, alone in the hospital. To meet the needs of COVID patients, services such as Emergency Medicine and Palliative Care have responded rapidly by adopting novel ways of practicing medicine. We describe the use of telepalliative medicine (TM) implemented in an emergency department (ED) setting to allow family members the ability to interact with their loved ones during critical illness, and even during the end of life. Use of this technology has helped facilitate goals of care discussions, in addition to providing contact and closure for both patients and their loved ones. CONCLUSION: We describe our rapid and ongoing implementation of TM consultation for our ED patients and discuss lessons learned and recommendations for others considering similar care models.

Conscious Proning: An Introduction of a Proning Protocol for Nonintubated, Awake, Hypoxic Emergency Department COVID-19 Patients.

The novel coronavirus, or COVID-19, has rapidly become a global pandemic. A major cause of morbidity and mortality due to COVID-19 has been the worsening hypoxia that, if untreated, can progress to acute respiratory distress syndrome (ARDS) and respiratory failure. Past work has found that intubated patients with ARDS experience physiological benefits to the prone position, because it promotes better matching of pulmonary perfusion to ventilation, improved secretion clearance, and recruitment of dependent areas of the lungs. We created a systemwide multi-institutional (New York-Presbyterian Hospital enterprise) protocol for placing awake, nonintubated, emergency department patients with suspected or confirmed COVID-19 in the prone position. In this piece, we describe the background literature and the approach we have taken at our institution as we care for a high burden of COVID-19 cases with respiratory symptoms.

Development and Utility of an ELISA Method for Sensitive and Specific Detection of IgE Antidrug Antibodies.

Biologics can potentially induce unwanted immune responses, leading to formation of antidrug antibodies (ADA) of various affinity, isotypes, and subclasses. Among them, antigen and drug-specific immunoglobulin E (IgE) antibodies have been reported to have potential correlation with hypersensitivity and anaphylaxis in particular. Recent regulatory guidance on immunogenicity testing has recommended the measurement of antigen-specific IgE antibodies for biologics with a reported high risk of anaphylaxis using assays with sensitivities in the high pg/mL to low ng/mL range. Nevertheless, IgE ADA remains challenging to detect due to their being the least abundant isotype in blood serum samples and the potential for interference in the bioanalytical methods due to high levels of endogenous immunoglobulin G (IgG) and immunoglobulin M (IgM) ADA, not to mention the nonspecific total serum IgE antibodies. Another challenge in developing IgE ADA assays is the need to create a surrogate drug-specific IgE antibody positive control to monitor the performance of the assay for the intended use. In this case study, utilizing a human IgE antidrug antibody positive control and a human IgE receptor as capture, an enzyme-linked immunosorbent assay (ELISA) method was developed for the measurement of IgE ADA, meeting the regulatory expectations, with excellent assay sensitivity, selectivity, specificity, and tolerance towards potential interference in serum samples. This assay format could be readily adapted and implemented to assess drug-specific IgE antibodies in the event of drug-related anaphylaxis in clinical and in nonclinical development programs.

Respiratory adjusted shock index for identifying occult shock and level of Care in Sepsis Patients.

OBJECTIVE: Early identification of shock allows for timely resuscitation. Previous studies note the utility of bedside calculations such as the shock index (SI) and quick sepsis-related organ failure assessment (qSOFA) to detect occult shock. Respiratory rate may also be an important marker of occult shock. The goal of our study was to evaluate whether using a modified SI with respiratory rate would improve identification of emergency department sepsis patients admitted to an ICU or stepdown unit. METHODS: A prospective, observational cohort study of the respiratory adjusted shock index (RASI), defined as HR/SBP × RR/10, was conducted. RASI was calculated from triage vital signs and compared to serum lactate. Primary outcome was admission to a higher level of care defined as ICU or stepdown unit. A multivariable logistic regression model including RASI, SI, lactate, age and sex was performed with disposition as the outcome variable. Areas under the curve (AUC) were calculated to detect occult shock and level of care for RASI, SI, and qSOFA. RESULTS: 408 patients were enrolled, 360 were included in the analysis. Regression analysis revealed that lactate (OR 1.55, z = 4.38, p < 0.0001) and RASI (OR 2.27, z = 3.03, p < 0.002) were predictive of need for higher level of care. The AUC for RASI, SI, and qSOFA to detect occult shock were 0.71, 0.6, and 0.61 respectively. RASI also had a significant AUC in predicting level of care at 0.75 compared to SI (0.64) and qSOFA (0.62). CONCLUSIONS: RASI may have utility as a rapid bedside tool for predicting critical illness in sepsis patients.

Cross-sectional Survey of Long-Term Care Facilities in the Rockaway Peninsula: Preparedness and Response During Hurricane Sandy.

BACKGROUND: Few studies have described the challenges experienced by long-term care facilities (LTCFs) following Hurricane Sandy. This study examined LTCF preparedness and experiences during and after the storm. METHODS: A cross-sectional survey was conducted 2 years after Hurricane Sandy to assess LTCF demographics, preparation, and post-storm resources. Surveys were conducted at LTCFs located on the Rockaway Peninsula of New York City. All LTCFs located in a heavily affected area were approached. RESULTS: Of 29 facilities, 1 had closed, 5 did not respond, 9 declined to participate, and 14 participated, yielding a response rate of 50% for open facilities. Twenty-one percent of the facilities had preparations specifically for hurricanes. More than 70% of the facilities had lost electricity, heat, and telephone service, and one-half had evacuated. Twenty-one percent of the facilities reported not receiving any assistance and over one-half reported that relief resources did not meet their needs. CONCLUSIONS: Many LTCFs lacked plans specific to such a large-scale event. Since nearly all of the LTCFs in the region were affected, preexisting transportation and housing plans may have been inadequate. Future preparation could include hazard-specific planning and reliance on resources from a wider geographic area. Access to electricity emerged as a top priority.
