Cancer pain management in the emergency department: a multicenter prospective observational trial of the Comprehensive Oncologic Emergencies Research Network (CONCERN)

Epidemiology of Non-Emergent Cancer-Related Emergency Department Visits in Korea between 2016 and 2020

PURPOSE

As people living with cancer increase in the aging society, cancer-related emergency department (ED) visits are also increasing. This study aimed to investigate the epidemiologic characteristics of non-emergent cancer-related ED visits using a nationwide ED database.

MATERIALS AND METHODS

A cross-sectional study was conducted using the National Emergency Department Information System (NEDIS) database. All cancer-related ED visits between 2016 and 2020 were included. The study outcome was non-emergent ED visits, defined as patients triaged into non-emergent condition at both the time of arrival at ED and discharge from ED and were discharged without hospitalization.

RESULTS

Among 1185871 cancer-related ED visits over 5 years, 19.0% (n=225491) were classified as non-emergent visits. While abdominal pain and fever are the top chief complaints in both emergent and non-emergent visits, non-emergent visits had high proportions of abdomen distension (4.8%), ascite (2.4%), and pain in lower limb (2.0%) compared with emergent visits. The cancer types with a high proportion of non-emergent visits were thyroid (32.4%) and prostate cancer (30.4%). Adults compared with children or older adults, female, medical aid insurance, urban/rural ED, direct-in compared with transfer-in, and weekend visit were associated with high odds for non-emergent visits.

CONCLUSION

Approximately 20% of cancer-related ED visits may be potentially non-emergent. A significant number of non-emergent patients visited the ED due to cancer-related symptoms. To improve the quality of care for people living with cancer, the expansion of supportive care resources besides of ED, including active symptom control, is necessary.

Immune-related adverse event in the emergency department: methodology of the immune-related emergency disposition index (IrEDi)

For many cancer patients, immune checkpoint inhibitors (ICIs) can be life-saving. However, the immune-related adverse events (irAEs) from ICIs can be debilitating and can quickly become severe or even be fatal. Often, irAEs will precipitate visits to the emergency department (ED). Therefore, early recognition and the decision to admit, observe, or discharge these patients from the ED can be key to a cancer patient's morbidity and mortality. ED clinicians typically make their decision for disposition (admit, observe, or discharge) within 2-6 h from their patient's ED presentation. However, irAEs are particularly challenging in the ED because of atypical presentations, the absence of classic symptoms, the delayed availability of diagnostic tests during the ED encounter, and the fast pace in the ED setting. At present, there is no single sufficiently large ED data source with clinical, biological, laboratory, and imaging data that will allow for the development of a tool that will guide early recognition and appropriate ED disposition of patients with potential irAEs. We describe an ongoing federally funded project that aims to develop an immune-related emergency disposition index (IrEDi). The project capitalizes on a multi-site collaboration among 4 members of the Comprehensive Oncologic Emergency Research Network (CONCERN): MD Anderson Cancer Center, Ohio State University, Northwestern University, and University of California San Diego. If the aims are achieved, the IrEDi will be the first risk stratification tool derived from a large racial/ethnically and geographically diverse population of cancer patients. The future goal is to validate irEDi in general EDs to improve emergency care of cancer patients on ICIs.

Fentanyl in cancer pain management: avoiding hasty judgments and discerning its potential benefits

Cancer pain is an important challenge in treatment and requires a rapid onset of action for its control. In particular, breakthrough cancer pain (BTcP) should be adequately controlled with a stable dose of a short-acting oral opioid. Fentanyl is a synthetic, highly selective opioid with many advantageous chemical properties, including high lipophilicity and distinct pharmacokinetic properties. It is recommended for pain management in a variety of settings, including acute pain, chronic pain and BTcP. To date, its variously designed formulations allow non-invasive administration; amongst others, sublingual fentanyl has proven useful in the management of BTcP and in improving the quality of life of patients with cancer. This review provides an update on the management of BTcP with fentanyl, with consideration of safety, as it remains an important tool in the treatment of cancer pain.

Daily pain and opioid administration in hospitalized patients with cancer: the importance of psychological factors, recent surgery, and current opioid use

ABSTRACT

Pain is common and variable in its severity among hospitalized patients with cancer. Although biopsychosocial factors are well established as modulators of chronic pain, less is known about what patient-level factors are associated with worse pain outcomes among hospitalized cancer patients. This prospective cohort study included patients with active cancer presenting to the emergency department (ED) with pain severity of ≥4/10 and followed pain outcomes longitudinally throughout hospital admission. Baseline demographic, clinical, and psychological factors were assessed on ED presentation, and daily average clinical pain ratings and opioid consumption during hospitalization were abstracted. Univariable and multivariable generalized estimating equation analyses examined associations of candidate biopsychosocial, demographic, and clinical predictors with average daily pain and opioid administration. Among 113 hospitalized patients, 73% reported pain as the primary reason for presenting to the ED, 43% took outpatient opioids, and 27% had chronic pain that predated their cancer. Higher pain catastrophizing ( B = 0.1, P ≤ 0.001), more recent surgery ( B = -0.2, P ≤ 0.05), outpatient opioid use ( B = 1.4, P ≤ 0.001), and history of chronic pain before cancer diagnosis ( B = 0.8, P ≤ 0.05) were independently associated with greater average daily pain while admitted to the hospital. Higher pain catastrophizing ( B = 1.6, P ≤ 0.05), higher anxiety ( B = 3.7, P ≤ 0.05), lower depression ( B = -4.9, P ≤ 0.05), metastatic disease ( B = 16.2, P ≤ 0.05), and outpatient opioid use ( B = 32.8, P ≤ 0.001) were independently associated with higher daily opioid administration. Greater psychological distress, especially pain catastrophizing, as well as pain and opioid use history, predicted greater difficulty with pain management among hospitalized cancer patients, suggesting that early assessment of patient-level characteristics may help direct consultation for more intensive pharmacologic and nonpharmacologic interventions.

Pain Management at the End of Life in the Emergency Department: A Narrative Review of the Literature and a Practical Clinical Approach

Access to pain management is a fundamental human right for all people, including those who are at the end of life (EOL). In end-stage patients, severe and uncontrolled pain is a common cause of admission to the emergency department (ED), and its treatment is challenging due to its complex, often multifactorial genesis. The aim of this narrative review was to identify the available literature on the management of severe EOL pain in the ED. The MEDLINE, SCOPUS, EMBASE, and CENTRAL databases were searched from inception to 1 April 2023 including randomised controlled trials, observational studies, systemic or narrative reviews, case reports, and guidelines on the management of EOL pain in the ED. A total of 532 articles were identified, and 9 articles were included (5 narrative reviews, 2 retrospective studies, and 2 prospective studies). Included studies were heterogeneous on the scales used and recommended for pain assessment and the recommended treatments. No study provided evidence for a better approach for EOL patients with pain in the ED. We provide a narrative summary of the findings and a review of the management of EOL pain in clinical practice, including (i) the identification of the EOL patients and unmet palliative care needs, (ii) a multidimensional, patient-centred assessment of the type and severity of pain, (iii) a multidisciplinary approach to the management of end-of-life pain, including an overview of non-pharmacological and pharmacological techniques; and (iv) the management of special situations, including rapid acute deterioration of chronic pain, breakthrough pain, and sedative palliation.

Benefits of Spiritual and Religious Support in the Pain Management of Cancer Patients: A Literature Scoping Review

Pain is one of the main symptoms of cancer and the most difficult to control due to its complexity as it can involve physical, psychological, social, and spiritual aspects. We proposed to summarize the scientific knowledge already published related to the influence of spirituality on pain therapy in cancer patients. Articles were searched in PubMed, SciELO, SciFinder, PsycInfo, and ScienceDirect databases using the following descriptors: "Spirituality," "Religion," "Religion," "Chronic Pain," "Pain Management" and "Cancer." A total of 68 articles were included and discussed. Most articles dealt with the influence of spirituality in palliative care, focussed on patient quality, and highlighted the importance of integrative oncology. Although few studies associated spirituality with chronic pain, most articles reported that spirituality could confer greater pain control.

Effect of Fu's subcutaneous needling for cancer pain management: protocol for a pragmatic randomised controlled trial

INTRODUCTION

Pain is a common symptom in patients with cancer, and pain management is crucial for these patients. Fu's subcutaneous needling (FSN) is a modern acupuncture therapy based on basic medicine commonly used in patients with pain. However, evidence of its effectiveness in treating cancer pain has not been systematically proven. Therefore, this pragmatic randomised controlled trial aims to evaluate the effectiveness and safety of FSN for cancer pain management.

METHODS AND ANALYSIS

Overall, 120 eligible patients will be recruited and randomly assigned into two groups using block randomisation. Both groups will be administered analgesic drugs according to the National Comprehensive Cancer Network guidelines. The treatment group will receive FSN therapy one time a day for 6 days. Additionally, we will assess analgesic consumption as the primary outcome and the Numerical Rating Scale, outbreak pain, symptom assessment and adverse events as secondary outcomes to evaluate the effect and safety of FSN in treating cancer pain. The incidence of adverse events will be monitored to assess the safety of FSN.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Ethics Committee of the First Affiliated Hospital of Guangzhou University of Chinese Medicine (approval No: K(2021)096). The results will be published in a peer-reviewed journal, and trial participants will be informed via email and/or phone calls.

Lung Cancer Supportive Care and Symptom Management

Lung cancer carries significant mortality and morbidity. In addition to treatment advances, supportive care may provide significant benefit for patients and their caregivers. A multidisciplinary approach is critical in addressing complications of lung cancer, including disease- and treatment-related complications, oncologic emergencies, symptom management and supportive care, and addressing the psychosocial needs of affected patients.

Cancer-related emergency and urgent care: expanding the research agenda

Purpose of review

Cancer-related emergency department (ED) visits often result in higher hospital admission rates than non-cancer visits. It has been estimated many of these costly hospital admissions can be prevented, yet urgent care clinics and EDs lack cancer-specific care resources to support the needs of this complex population. Implementing effective approaches across different care settings and populations to minimize ED and urgent care visits improves oncologic complication management, and coordinating follow-up care will be particularly important as the population of cancer patients and survivors continues to increase. The National Cancer Institute (NCI) and the Office of Emergency Care (OECR) convened a workshop in December 2021, “Cancer-related Emergency and Urgent Care: Prevention, Management, and Care Coordination” to highlight progress, knowledge gaps, and research opportunities. This report describes the current landscape of cancer-related urgent and emergency care and includes research recommendations from workshop participants to decrease the risk of oncologic complications, improve their management, and enhance coordination of care.

Recent findings

Since 2014, NCI and OECR have collaborated to support research in cancer-related emergency care. Workshop participants recommended a number of promising research opportunities, as well as key considerations for designing and conducting research in this area. Opportunities included better characterizing unscheduled care services, identifying those at higher risk for such care, developing care delivery models to minimize unplanned events and enhance their care, recognizing cancer prevention and screening opportunities in the ED, improving management of specific cancer-related presentations, and conducting goals of care conversations.

Summary

Significant progress has been made over the past 7 years with the creation of the Comprehensive Oncologic Emergency Research Network, broad involvement of the emergency medicine and oncology communities, establishing a proof-of-concept observational study, and NCI and OECR’s efforts to support this area of research. However, critical gaps remain.

Characteristics and Outcomes of Patients with Cancer Pain Placed in an Emergency Department Observation Unit

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.

Oncologic emergencies and urgencies: A comprehensive review

Patients with advanced cancer generate 4 million visits annually to emergency departments (EDs) and other dedicated, high-acuity oncology urgent care centers. Because of both the increasing complexity of systemic treatments overall and the higher rates of active therapy in the geriatric population, many patients experiencing acute decompensations are frail and acutely ill. This article comprehensively reviews the spectrum of oncologic emergencies and urgencies typically encountered in acute care settings. Presentation, underlying etiology, and up-to-date clinical pathways are discussed. Criteria for either a safe discharge to home or a transition of care to the inpatient oncology hospitalist team are emphasized. This review extends beyond familiar conditions such as febrile neutropenia, hypercalcemia, tumor lysis syndrome, malignant spinal cord compression, mechanical bowel obstruction, and breakthrough pain crises to include a broader spectrum of topics encompassing the syndrome of inappropriate antidiuretic hormone secretion, venous thromboembolism and malignant effusions, as well as chemotherapy-induced mucositis, cardiomyopathy, nausea, vomiting, and diarrhea. Emergent and urgent complications associated with targeted therapeutics, including small molecules, naked and drug-conjugated monoclonal antibodies, as well as immune checkpoint inhibitors and chimeric antigen receptor T-cells, are summarized. Finally, strategies for facilitating same-day direct admission to hospice from the ED are discussed. This article not only can serve as a point-of-care reference for the ED physician but also can assist outpatient oncologists as well as inpatient hospitalists in coordinating care around the ED visit.

Psychological Evaluation of Patients With Cancer Presenting to the Emergency Department With Pain: Independent Predictors of Worse Pain Severity, Interference, and Higher Hourly Opioid Administration

PURPOSE

Pain is a common complaint in patients with cancer presenting to the emergency department (ED). This prospective study evaluated whether biopsychosocial factors could help predict cancer patients with risk of higher pain severity, pain interference, and opioid consumption.

METHODS

Patients with cancer presenting to the ED with a complaint of moderate-severe pain (≥ 4/10-numeric rating scale) completed validated self-report measures assessing sociodemographics, cancer-related treatments, pain severity and interference, medication use, and psychological symptoms (depression, anxiety, pain catastrophizing, and sleep disturbance). Opioids administered and subsequent hospitalization were abstracted. Univariable and multivariable regression analyses assessed factors associated with pain-related outcomes.

RESULTS

Participants (n = 175) presented with a variety of cancer types, with 76% having metastatic disease and 42% reporting current outpatient opioid use. Higher pain catastrophizing, lower depressive symptoms, lower income, outpatient opioid use, and historical chronic pain were independently associated with worse pain (P ≤ .05). Higher pain catastrophizing, anxiety, sleep disturbance, outpatient opioid use, and education were independently associated with worse pain interference (P ≤ .05). The sole independent predictor of ED opioid administration was outpatient opioid use. Patients taking outpatient opioids were younger, had lower health literacy, worse pain catastrophizing, sleep disturbance, depression/anxiety, and greater rates of metastatic cancer and cancer-related surgery (P ≤ .05).

CONCLUSION

Biopsychosocial factors, particularly pain catastrophizing, remained significantly associated with worse pain outcomes for patients with cancer in the ED even after controlling for demographic and clinical variables. Patient outpatient opioid use was independently associated with worse pain, interference, and greater opioid administration, identifying this as a marker for who may benefit most from adjuvant pharmacologic and behavioral interventions.

Ultrasound-Guided Peripheral Nerve Blocks: A Practical Review for Acute Cancer-Related Pain

PURPOSE OF REVIEW

Ultrasound-guided regional techniques, including catheter-based approaches, are a subset of interventional therapies that have gained interest as an option for managing acute cancer-related pain. The authors sought to review the available published evidence and to discuss practical recommendations for expanding access to such therapies.

RECENT FINDINGS

In a MEDLINE/Pubmed search of ultrasound-guided peripheral nerve blocks and peripheral nerve catheters for specific anatomic targets, a total of 28 case reports and case series were identified. Included studies described improved analgesia and reduced opioid requirements with highly variable duration of effect. Current level of evidence remains limited. Pain is a symptom that markedly impacts the quality of life of cancer patients and ultrasound-guided regional techniques are a promising therapeutic option albeit with a limited evidence base. Practical recommendations offered for coordinating access to such therapies in the inpatient, emergency department, and outpatient settings may expand interest and facilitate higher quality research.

Different Machine Learning Approaches for Implementing Telehealth-Based Cancer Pain Management Strategies

Background: The most effective strategy for managing cancer pain remotely should be better defined. There is a need to identify those patients who require increased attention and calibrated follow-up programs. Methods: Machine learning (ML) models were developed using the data prospectively obtained from a single-center program of telemedicine-based cancer pain management. These models included random forest (RF), gradient boosting machine (GBM), artificial neural network (ANN), and the LASSO−RIDGE algorithm. Thirteen demographic, social, clinical, and therapeutic variables were adopted to define the conditions that can affect the number of teleconsultations. After ML validation, the risk analysis for more than one remote consultation was assessed in target individuals. Results: The data from 158 patients were collected. In the training set, the accuracy was about 95% and 98% for ANN and RF, respectively. Nevertheless, the best accuracy on the test set was obtained with RF (70%). The ML-based simulations showed that young age (<55 years), lung cancer, and occurrence of breakthrough cancer pain help to predict the number of remote consultations. Elderly patients (>75 years) with bone metastases may require more telemedicine-based clinical evaluations. Conclusion: ML-based analyses may enable clinicians to identify the best model for predicting the need for more remote consultations. It could be useful for calibrating care interventions and resource allocation.

Characterization of older adults with cancer seeking acute emergency department care: A prospective observational study

INTRODUCTION

Disparities in care of older adults in cancer treatment trials and emergency department (ED) use exist. This report provides a baseline description of older adults ≥65 years old who present to the ED with active cancer.

MATERIALS AND METHODS

Planned secondary analysis of the Comprehensive Oncologic Emergencies Research Network observational ED cohort study sponsored by the National Cancer Institute. Of 1564 eligible adults with active cancer, 1075 patients were prospectively enrolled, of which 505 were ≥ 65 years old. We recruited this convenience sample from eighteen participating sites across the United States between February 1, 2016 and January 30, 2017.

RESULTS

Compared to cancer patients younger than 65 years of age, older adults were more likely to be transported to the ED by emergency medical services, have a higher Charlson Comorbidity Index score, and be admitted despite no significant difference in acuity as measured by the Emergency Severity Index. Despite the higher admission rate, no significant difference was noted in hospitalization length of stay, 30-day mortality, ED revisit or hospital admission within 30 days after the index visit. Three of the top five ED diagnoses for older adults were symptom-related (fever of other and unknown origin, abdominal and pelvic pain, and pain in throat and chest). Despite this, older adults were less likely to report symptoms and less likely to receive symptomatic treatment for pain and nausea than the younger comparison group. Both younger and older adults reported a higher symptom burden on the patient reported Condensed Memorial Symptom Assessment Scale than to ED providers. When treating suspected infection, no differences were noted in regard to administration of antibiotics in the ED, admissions, or length of stay ≤2 days for those receiving ED antibiotics.

DISCUSSION

We identified several differences between older (≥65 years old) and younger adults with active cancer seeking emergency care. Older adults frequently presented for symptom-related diagnoses but received fewer symptomatic interventions in the ED suggesting that important opportunities to improve the care of older adults with cancer in the ED exist.

Palliative care models for patients living with advanced cancer: a narrative review for the emergency department clinician

Eighty-one percent of persons living with cancer have an emergency department (ED) visit within the last 6 months of life. Many cancer patients in the ED are at an advanced stage with high symptom burden and complex needs, and over half is admitted to an inpatient setting. Innovative models of care have been developed to provide high quality, ambulatory, and home-based care to persons living with serious, life-limiting illness, such as advanced cancer. New care models can be divided into a number of categories based on either prognosis (e.g., greater than or less than 6 months), or level of care (e.g., lower versus higher intensity needs, such as intravenous pain/nausea medication or frequent monitoring), and goals of care (e.g., cancer-directed treatment versus symptom-focused care only). We performed a narrative review to (1) compare models of care for seriously ill cancer patients in the ED and (2) examine factors that may hasten or impede wider dissemination of these models.

Approach to Cancer Pain Management in Emergency Departments: Comparison of General and Oncology Based Settings

Cancer-related pain constitutes a dominant reason for admission to emergency services, and a significant patient and healthcare challenge. Evidence points to the rising prevalence of opioid misuse in this patient group. We sought to compare drug delivery in an oncology-dedicated emergency department (OED) and a general emergency department (GED) within the same hospital. As such, we obtained patient and drug-related data for OED and GED during a designated three-month period, and compared them using Fisher’s exact test, chi-square tests and the Mann-Whitney test. In total, 584 patients had 922 visits to emergency services (OED n = 479; GED n = 443), and were given 1478 drugs (OED n = 557; GED n = 921). Pain was a prominent chief complaint among visitors to the OED (17%) and GED (21%). Approximately a fifth of all drugs used were analgesics (OED—18.5%; GED—20.4%), however, in the GED, 51.6% (n = 97) were used for non-pain-related admissions, compared with 33.0% (n = 34) in OED. Opioid usage significantly differed between emergency settings. The GED administered three times as many intravenous opioids (p <0.001), a narrower spectrum of oral and intravenous drugs (p = 0.003) and no rapid-acting opioids, significantly fewer pain adjuvants (10.9% versus 18.7%, p < 0.001), and, finally, non-guideline-recommended drugs for pain, such as meperidine and benzodiazepines. Taken together, compared with the GED, the management of cancer-related pain in the OED was more personalized, and characterized by fewer intravenous opioids, enhanced diversity in drug type, route and method of delivery. Efforts should be directed toward reduction of disparities in the treatment of cancer pain in emergency settings.

The Value Proposition of Observation Medicine in Managing Acute Oncologic Pain

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. 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.

Outcomes of Patients Placed in an Emergency Department Observation Unit of a Comprehensive Cancer Center

Emergency department observation units (EDOUs) have been shown to decrease length of stay and improve cost effectiveness. Yet, compared with noncancer patients, patients with cancer are placed in EDOUs less often. In this study, we aimed to describe patients who were placed in a cancer center's EDOU to discern their clinical characteristics and outcomes.
