Objective: Providing high-quality, safe, and consistent care for patients with cancer in the emergency department (ED) poses unique challenges. To better understand these challenges, we surveyed oncologists and emergency medicine (EM) physicians across five institutions to identify key areas for improvement in oncologic EM. Methods: In this multi-institutional, cross-sectional qualitative study, a semi-structured survey was administered to EM attending and resident physicians and medical and surgical oncologists across five institutions in 2023. We assessed the open-ended questionnaire responses using thematic analysis; codes were created and collated to generate initial themes. The themes were then reviewed according to specialty for coherence and non-repetition and finalized. Results: Of the 302 surveys accessed, 185 (61.3%) had complete responses. Three main domains of issues emerged: systems-based challenges, direct patient care-related issues, and knowledge gaps. The issues most frequently perceived by oncologist survey respondents were long delays in care (41%), variability in care (25%), and communication issues between the EM physician and oncologist (14%). The issues most frequently perceived by EM physician survey respondents were knowledge gaps in cancer therapeutics (40%) and in general oncologic emergencies (23%); physician comfort level (14%); the timing and/or location of initial discussions about goals of care (13%); and challenges with the follow-up process (12%). Conclusions: Incorporating an interdisciplinary approach to patient care in the ED, improved EM oncologic education, and the development of oncologic specialized EDs may enhance the quality, safety, and consistency of care for patients with cancer in the ED.

Immune checkpoint inhibitors (ICI), such as pembrolizumab, nivolumab, durvalumab and ipilimumab, have significantly enhanced survival rates for multiple cancer types such as non-small cell lung cancer, melanoma, Hodgkin lymphoma, and breast cancer, and they have emerged as an adjunct or primary therapy for malignant disease. Approximately 40% of patients with cancer on ICI therapy experience side effects called immune-related adverse events (irAE). While not the most common, pulmonary toxicities can be rapidly progressive, potentially fatal, and pose a three-fold increased risk for requiring intensive care unit-level of care. Pneumonitis is a focal or diffuse inflammation of the lung parenchyma, and clinical manifestations may be highly variable. While the onset is generally observed 6–12 weeks after the initiation of therapy, drug toxicity can develop rapidly within days after the first infusion or many months into therapy. Pneumonitis symptoms can be subtle or non-specific; therefore, a thorough and systematic evaluation considering other possible etiologies is crucial. Moreover, extrapulmonary findings, such as skin lesions, colitis, or endocrinopathies, should raise suspicion for irAE as drug toxicity can affect multiple organs simultaneously. Due to the significant overlap of clinical features between ICI-associated pneumonitis and respiratory infections, it can be challenging to differentiate the two conditions based on clinical presentation alone. A multidisciplinary approach to management is recommended for the treatment of ICI-associated pneumonitis, and classification of severity helps to guide interventions. Treatment options in more severe cases include systemic immunosuppression. Given the increased use of ICIs and greater probability that patients with ICI-associated pneumonitis will be seen in the emergency department, we aimed to provide a comprehensive framework for the diagnosis and management. In addition, identifying potential challenges in diagnosis and/or other contributors of respiratory symptoms and radiographic manifestations is highlighted.

Background/Objectives: Patients with advanced cancer often present to the emergency department (ED) with pain and distressing symptoms that are not systematically evaluated. The current study investigated the association of symptom severity with the diagnosis of delirium and short-term survival. Methods: In this secondary analysis of a prospective randomized study of delirium among advanced cancer patients in the ED, in which symptoms were assessed by the MD Anderson Symptom Inventory (MDASI), we analyzed the distribution of MDASI item scores by 90-day mortality (Kolmogorov–Smirnov), the association of MDASI item scores with short-term mortality (logistic regression models), and the symptoms in those with or without delirium (Mann–Whitney U test or chi-square test). Results: Of the 243 patients included, 222 (91.4%) had complete MDASI scores. The MDASI median symptom scores for pain, fatigue, and interference with work were the highest. A significant difference in MDASI item score distribution with 90-day mortality was observed for fatigue (p = 0.018), shortness of breath (p < 0.001), difficulty remembering (p = 0.038), lack of appetite (p = 0.035), drowsiness (p < 0.001), feeling sad (p = 0.031), and interference with walking (p < 0.001). In multivariable logistic regression models, shortness of breath (adjusted OR 1.15, 95% CI 1.04–1.26, p = 0.005) and drowsiness (adjusted OR 1.17, 95% CI 1.05–1.33, p = 0.008) were associated with 90-day mortality, adjusting for age, race, performance status, and cancer type. The median total MDASI score was significantly higher in patients with delirium than in those without (88, IQR 83–118 vs. 80, IQR 55–104; p < 0.001). Conclusions: Patients with advanced cancer presenting to the ED had severe symptoms, some of which were associated with shorter survival. These findings underscore the necessity of systematic symptom assessment, focusing on shortness of breath, drowsiness, fatigue, difficulty remembering, lack of appetite, feeling sad, and feeling distressed, to enhance clinical decision-making and improve the care of patients with advanced cancer. Additional longitudinal studies are needed to evaluate the improvement in symptoms and quality of life for these patients.

Immune checkpoint inhibitors (ICIs) have significantly transformed cancer treatment, but their use is linked to immune-related adverse events (irAEs), including the rare ICI-associated myocarditis, myositis, and myasthenia gravis (MMM) overlap syndrome. This systematic review aims to highlight MMM’s clinical implications in emergency departments. PubMed and Embase were searched using a specific search strategy. Reports were eligible for inclusion if all three conditions were present and associated with the use of an ICI. Data were extracted by independent reviewers using the Rayyan web application for systematic reviews. Descriptive statistics and qualitative synthesis were used to summarize demographic, clinical, and treatment data for the reported cases. Among 50 cases, predominantly associated with melanoma, lung cancer, and renal cancer, the in-hospital mortality rate was 38.0%. The most commonly presenting symptoms were ptosis (58%), dyspnea (48%), diplopia (42%), or myalgia (36%). The median time from ICI initiation to MMM presentation was 21 days (interquartile range: 15–28 days). Corticosteroids were the primary treatment for the irAEs. MMM, a rare but potentially fatal complication of ICI therapy, requires prompt recognition in emergency settings. Corticosteroids should be initiated if suspected, without waiting for confirmation. Multidisciplinary collaboration is vital for diagnosis and treatment planning. Research on MMM’s link to specific cancers and ICIs is imperative for better risk assessment and interventions.

Objective: The core content of emergency medicine (EM) residency training includes the management of oncologic emergencies; however, documented knowledge gaps continue to exist in this subtopic. This study represents a targeted needs assessment as indicated by Step 2 of Kern's curriculum design to determine the specific training gaps to be addressed within the oncologic EM curriculum.Methods: A multi‐institutional cross‐sectional survey of oncologists (surgical and medical) and emergency physicians (attendings and residents) was conducted during 2023 at five institutions. The voluntary survey consisted of general and specialty‐specific questions exploring gaps in oncologic emergency–specific training/education topics. Descriptive statistics reported responses as frequencies and percentages.Results: Of the 833 surveys sent across the five sites, 302 (36.3%) were accessed by link; of these, 271 (89.7%) surveys were completed. There were no differences in the responses between early and later respondents and no differences in the characteristics of respondents between sites. A vast majority of the oncologist and EM groups (91.2% and 83.0%, respectively) reported a belief that emergency physicians would benefit from additional oncologic emergency training. Our survey identified 16 important topics for inclusion in an oncologic EM curriculum, including five topics not present on the 2022 Model of Clinical Practice of Emergency Medicine.Conclusions: Based on this needs assessment, an oncologic EM curriculum should include the topics listed under oncologic emergencies in the 2022 Model of the Clinical Practice of Emergency Medicine along with our respondent‐identified topics of radiation therapy adverse effects, stem cell transplant complications, and the management of cancer‐specific postsurgical complications, pain, and common diseases in patients with cancer.

Pain remains an undertreated complication of cancer, with poor pain control decreasing patients’ quality of life. Traditionally, patients presenting to an emergency department with pain have only had two dispositions available to them: hospitalization or discharge. A third emerging healthcare environment, the emergency department observation unit (EDOU), affords patients access to a hospital’s resources without hospitalization. To define the role of an EDOU in the management of cancer pain, we conducted a retrospective study analyzing patients placed in an EDOU with uncontrolled cancer pain for one year. Patient characteristics were summarized using descriptive statistics and predictors of disposition from the EDOU and were identified with univariate and multivariate analyses. Most patients were discharged home, and discharged patients had low 72-hour revisit and 30-day mortality rates. Significant predictors of hospitalization were initial EDOU pain score (odds ratio (OR) = 1.12; 95% CI 1.06–1.19; p < 0.001) and supportive care (OR = 2.04; 95% CI 1.37–3.04; p < 0.001) or pain service (OR = 2.67; 95% CI 1.63–4.40; p < 0.001) consultations. We concluded that an EDOU appears to be the appropriate venue to care for a subsegment of patients presenting to an emergency department with cancer pain, with patients receiving safe care as well as appropriate consultation and admission when indicated.

Purpose of Review Despite recommended best practice guidelines, pain remains an ongoing but undertreated symptom in patients with cancer, many of whom require emergency department evaluation for acute oncologic pain. A significant proportion of these patients are hospitalized for pain management, which increases healthcare costs and exposes patients to the risks of hospitalization. We reviewed the literature on observation medicine: an emerging mode of healthcare delivery which can offer patients with acute pain access to a hospital’s pain management solutions and specialists without an inpatient hospitalization. Specifically, we appraised the role of observation medicine in acute pain management and its financial implications in order to consider its potential impact on the management of acute oncologic pain. Recent Findings Recent evidence shows that observation medicine has the potential to decrease short-stay hospitalizations in cancer patients presenting with various concerns, including pain. Summary Observation medicine is reported to be successful in providing comprehensive and cost-effective care for non-cancer patients with acute pain, making it a promising alternative to short-stay hospitalizations for cancer patients with acute oncologic pain.
