Analysis of Diagnoses, Symptoms, Medications, and Admissions Among Patients With Cancer Presenting to Emergency Departments

A systematic review and meta-analysis of the impacts of germline pharmacogenomics on severe toxicity and symptom burden in adult patients with cancer

The clinical application of Pharmacogenomics (PGx) has improved patient safety. However, comprehensive PGx testing has not been widely adopted in clinical practice, and significant opportunities exist to further optimize PGx in cancer care. This systematic review and meta-analysis aim to evaluate the safety outcomes of reported PGx-guided strategies (Analysis 1) and identify well-studied emerging pharmacogenomic variants that predict severe toxicity and symptom burden (Analysis 2) in patients with cancer. We searched MEDLINE, EMBASE, CENTRAL, clinicaltrials.gov, and International Clinical Trials Registry Platform from inception to January 2023 for clinical trials or comparative studies evaluating PGx strategies or unconfirmed pharmacogenomic variants. The primary outcomes were severe adverse events (SAE; ≥ grade 3) or symptom burden with pain and vomiting as defined by trial protocols and assessed by trial investigators. We calculated pooled overall relative risk (RR) and 95% confidence interval (95%CI) using random effects models. PROSPERO, registration number CRD42023421277. Of 6811 records screened, six studies were included for Analysis 1, 55 studies for Analysis 2. Meta-analysis 1 (five trials, 1892 participants) showed a lower absolute incidence of SAEs with PGx-guided strategies compared to usual therapy, 16.1% versus 34.0% (RR = 0.72, 95%CI 0.57-0.91, p = 0.006, I2 = 34%). Meta-analyses 2 identified nine medicine(class)-variant pairs of interest across the TYMS, ABCB1, UGT1A1, HLA-DRB1, and OPRM1 genes. Application of PGx significantly reduced rates of SAEs in patients with cancer. Emergent medicine-variant pairs herald further research into the expansion and optimization of PGx to improve systemic anti-cancer and supportive care medicine safety and efficacy.

Predictive factors of basic palliative and hospice care among patients with cancer visiting the emergency department in a Hungarian tertiary care center

Introduction

Patients with advanced cancer tend to utilize the services of the health care system, particularly emergency departments (EDs), more often, however EDs aren't necessarily the most ideal environments for providing care to these patients. The objective of our study was to analyze the clinical and demographic characteristics of advanced patients with cancer receiving basic palliative care (BPC) or hospice care (HC), and to identify predictive factors of BPC and HC prior to their visit to the ED, in a large tertiary care center in Hungary.

Methods

A retrospective, detailed analysis of patients receiving only BPC or HC, out of 1512 patients with cancer visiting the ED in 2018, was carried out. Sociodemographic and clinical data were collected via automated and manual chart review. Patients were followed up to determine length of survival. Descriptive and exploratory statistical analyses were performed.

Results

Hospital admission, multiple (≥4x) ED visits, and respiratory cancer were independent risk factors for receiving only BPC (OR: 3.10, CI: 1.90-5.04; OR: 2.97, CI: 1.50-5.84; OR: 1.82, CI: 1.03-3.22, respectively), or HC (OR: 2.15, CI: 1.26-3.67; OR: 4.94, CI: 2.51-9.71; OR: 2.07, CI: 1.10-3.91). Visiting the ED only once was found to be a negative predictive factor for BPC (OR: 0.28, CI: 0.18-0.45) and HC (OR: 0.18, 0.10-0.31) among patients with cancer visiting the ED.

Conclusions

Our study is the first from this European region to provide information regarding the characteristics of patients with cancer receiving BPC and HC who visited the ED, as well as to identify possible predictive factors of receiving BPC and HC. Our study may have relevant implications for health care planning strategies in practice.

Why is end-of-life inpatient cost high among cancer patients? A prospective cohort study

BACKGROUND

Inpatient cost for cancer patients is high during the last year of life, but reasons for this are not understood. We aim to understand the type of hospital admissions and inpatient services associated with an increase in inpatient cost in last year of life.

METHODS

We used survey and billing records of 439 deceased patients with a solid metastatic cancer, enrolled in a prospective cohort study. Based on cost per day of inpatient admissions, we classified admissions as low- or high-intensity. We decomposed the inpatient cost into cost for different inpatient services. We examined the inpatient cost in the last year of life. We also assessed patient characteristics associated with higher inpatient cost in the next 3 months.

RESULTS

Towards death, proportion of inpatient cost for "maintenance care" increased while that for intensive care unit (ICU) and surgeries decreased. Low-intensity, compared to high-intensity admissions had a higher proportion of cost for "maintenance care" and a lower proportion for surgeries and ICU. Number of low-intensity admissions increased more steeply towards death than high-intensity admissions. Both admission types contributed equally to the share of inpatient cost. Older patients were less likely to have a high-intensity admission (β:-0.01, CI: -0.02, 0.00). Greater preference for life extension (β: 0.06, CI: 0.01, 0.11) and inaccurate prognostic belief were associated with higher cost of high-intensity admissions (β: 0.32, CI: 0.03, 0.62).

CONCLUSIONS

Findings suggest that inpatient costs in last year of life may be reduced if maintenance care is availed in low-cost settings such as hospice/palliative care alongside steps to reduce non-beneficial surgeries and ICU admissions.

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.

A secondary analysis: the impact of pre-existing chronic pain among patients with cancer presenting to the emergency department with acute pain

PURPOSE

Patients with cancer may experience pain from cancer itself or its treatment. Additionally, chronic pain (CP) predating a patient's cancer diagnosis may make the etiology of pain less clear and the management of pain more complex. In this brief report, we investigated differences in biopsychosocial characteristics, pain severity, and opioid consumption, comparing groups of cancer patients with and without a history of CP who presented to the emergency department (ED) with a complaint of cancer-related pain.

METHODS

This secondary analysis of a prospective cohort study included patients with cancer who presented to the ED with a complaint of pain (≥ 4/10). Sociodemographic, clinical, psychological, and pain characteristics were assessed in the ED and subsequent hospitalization. Mann-Whitney U-, T-, and Chi-square tests were used to compare differences between patients with and without pre-existing CP before cancer.

RESULTS

Patients with pre-existing CP had lower income (p = 0.21) and less formal education (p = 0.25) and were more likely to have a diagnosis of depression or substance use disorder (p < 0.01). Patients with pre-existing CP reported significantly greater pain severity in the ED and during hospitalization compared to those without pre-existing CP (p < 0.05), despite receiving greater amounts of opioid analgesics (p = 0.036).

CONCLUSION

Identifying a history of pre-existing CP during intake may help identify patients with cancer with difficult to manage pain, who may particularly benefit from multimodal interventions and supportive care. In addition, referral of these patients for the management of co-occurring pain disorders may help decrease the usage of the ED for undertreated pain.

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.

Drivers of Emergency Department Use Among Oncology Patients in the Era of Novel Cancer Therapeutics: A Systematic Review

BACKGROUND

Patients diagnosed with cancer are frequent users of the emergency department (ED). While many visits are unavoidable, a significant portion may be potentially preventable ED visits (PPEDs). Cancer treatments have greatly advanced, whereby patients may present with unique toxicities from targeted therapies and are often living longer with advanced disease. Prior work focused on patients undergoing cytotoxic chemotherapy, and often excluded those on supportive care alone. Other contributors to ED visits in oncology, such as patient-level variables, are less well-established. Finally, prior studies focused on ED diagnoses to describe trends and did not evaluate PPEDs. An updated systematic review was completed to focus on PPEDs, novel cancer therapies, and patient-level variables, including those on supportive care alone.

METHODS

Three online databases were used. Included publications were in English, from 2012-2022, with sample sizes of ≥50, and reported predictors of ED presentation or ED diagnoses in oncology.

RESULTS

45 studies were included. Six studies highlighted PPEDs with variable definitions. Common reasons for ED visits included pain (66%) or chemotherapy toxicities (69.1%). PPEDs were most frequent amongst breast cancer patients (13.4%) or patients receiving cytotoxic chemotherapy (20%). Three manuscripts included immunotherapy agents, and only one focused on end-of-life patients.

CONCLUSION

This updated systematic review highlights variability in oncology ED visits during the last decade. There is limited work on the concept of PPEDs, patient-level variables and patients on supportive care alone. Overall, pain and chemotherapy toxicities remain key drivers of ED visits in cancer patients. Further work is needed in this realm.

Healthcare professionals' and consumers' knowledge, attitudes, perspectives, and education needs in oncology pharmacogenomics: A systematic review

Clinical implementation of pharmacogenomic (PGx)-guided prescribing in oncology lags behind research evidence generation. We aimed to identify healthcare professionals' (HCPs) and consumers' knowledge, attitudes, perspectives, and education needs to inform strategies for implementation of scalable and sustainable oncology PGx programs. Systematic review of original articles indexed in EMBASE, EMCARE, MEDLINE, and PsycInfo from January 2012 until June 2022, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and using the Mixed Methods Appraisal Tool. PROSPERO registration number CRD42022352348. Of 1442 identified studies; 23 met inclusion criteria with 87% assessed high quality. Of these, 52% reported on HCPs, 35% on consumers, and 13% on both HCPs and consumers. Most were conducted in the United States (70%) and included multiple cancer types (74%). Across studies, HCPs and consumers mostly perceived value in PGx, however, both groups reported barriers to utilization, including cost, lack of consistent recommendations across guidelines, and limited knowledge among HCPs; test accuracy, clear testing benefits, and genomic information confidentiality among consumers. HCPs and consumers value and want to engage in PGx strategies in oncology care, however, are inhibited by unmet needs and practice and knowledge gaps. Implementation strategies aimed at addressing these issues may best support increased PGx uptake in oncology practice.

An integrative review of adult cancer patients' experiences of nursing telephone and virtual triage systems for symptom management

PURPOSE

Telephone and virtual triage services are becoming increasingly common in ambulatory oncology settings. Few studies have evaluated their implementation from the perspective of service users. This study aims to evaluate the experiences of engaging with nurse-delivered telephone and virtual triage systems for symptom management among people undergoing cancer treatment.

METHODS

An integrative review was undertaken. MEDLINE, CINAHL, PsycInfo, Academic Search Complete and Scopus were systematically searched. Twelve publications met the inclusion criteria, and data related to cancer patients' perceptions of the triage process were extracted and analysed.

RESULTS

Telephone-based (n=7), app-based (n=5) and video-based teleconferencing (n=2) triage systems were evaluated positively overall, enhancing ease of health system navigation, avoidance of emergency department for consultation, and the information, reassurance and support provided to support self-management of symptoms. However, several factors influenced the users' engagement with triage services, including confidence to articulate symptoms, limited opening hours, waiting times for initial triage or follow-up and digital literacy. Collectively, these factors contributed to delayed reporting or under-reporting of symptoms, undermining the potential impact of services. Studies included variable reporting of intervention characteristics, including the qualification of nurses delivering and leading services.

CONCLUSIONS

Future evaluations of triage services must give greater consideration to the characterisation of interventions to ensure transferability, including nursing roles and qualifications. To ensure effective intervention and optimal supportive care for symptom management, patients must be prepared to engage triage services early. Future evaluations must ensure the impact of digital literacy on engagement with, and experience of, virtual triage is investigated.

Systematic Review of Genetic Polymorphisms Associated with Acute Pain Induced by Radiotherapy for Head and Neck Cancers

Background/objective

Pain is the most common acute symptom following radiation therapy (RT) for head and neck cancer (HNC). The multifactorial origin of RT-induced pain makes it highly challenging to manage. Multiple studies were conducted to identify genetic variants associated with cancer pain, however few of them focused on RT-induced acute pain. In this review, we summarize the potential mechanisms of acute pain after RT in HNC and identify genetic variants associated with RT-induced acute pain and relevant acute toxicities.

Methods

A comprehensive search of Ovid Medline, EMBASE and Web of Science databases using terms including "Variants", "Polymorphisms", "Radiotherapy", "Acute pain", "Acute toxicity" published up to February 28, 2022, was performed by two reviewers. Review articles and citations were reviewed manually. The identified SNPs associated with RT-induced acute pain and toxicities were reported, and the molecular functions of the associated genes were described based on genetic annotation using The Human Gene Database; GeneCards.

Results

A total of 386 articles were identified electronically and 8 more articles were included after manual search. 21 articles were finally included. 32 variants in 27 genes, of which 25% in inflammatory/immune response, 20% had function in DNA damage response and repair, 20% in cell death or cell cycle, were associated with RT-inflammatory pain and acute oral mucositis or dermatitis. 4 variants in 4 genes were associated with neuropathy and neuropathic pain. 5 variants in 4 genes were associated with RT-induced mixed types of post-RT-throat/neck pain.

Conclusion

Different types of pain develop after RT in HNC, including inflammatory pain; neuropathic pain; nociceptive pain; and mixed oral pain. Genetic variants involved in DNA damage response and repair, cell death, inflammation and neuropathic pathways may affect pain presentation post-RT. These variants could be used for personalized pain management in HNC patients receiving RT.

Temporal characterization of acute pain and toxicity kinetics during radiation therapy for head and neck cancer. A retrospective study

Objectives

Pain during Radiation Therapy (RT) for oral cavity/oropharyngeal cancer (OC/OPC) is a clinical challenge due to its multifactorial etiology and variable management. The objective of this study was to define complex pain profiles through temporal characterization of pain descriptors, physiologic state, and RT-induced toxicities for pain trajectories understanding.

Materials and methods

Using an electronic health record registry, 351 OC/OPC patients treated with RT from 2013 to 2021 were included. Weekly numeric scale pain scores, pain descriptors, vital signs, physician-reported toxicities, and analgesics were analyzed using linear mixed effect models and Spearman's correlation. Area under the pain curve (AUCpain) was calculated to measure pain burden over time.

Results

Median pain scores increased from 0 during the weekly visit (WSV)-1 to 5 during WSV-7. By WSV-7, 60% and 74% of patients reported mouth and throat pain, respectively, with a median pain score of 5. Soreness and burning pain peaked during WSV-6/7 (51%). Median AUCpain was 16% (IQR (9.3-23)), and AUCpain significantly varied based on gender, tumor site, surgery, drug use history, and pre-RT pain. A temporal increase in mucositis and dermatitis, declining mean bodyweight (-7.1%; P < 0.001) and mean arterial pressure (MAP) 6.8 mmHg; P < 0.001 were detected. Pulse rate was positively associated while weight and MAP were negatively associated with pain over time (P < 0.001).

Conclusion

This study provides insight on in-depth characterization and associations between dynamic pain, physiologic, and toxicity kinetics. Our findings support further needs of optimized pain control through temporal data-driven clinical decision support systems for acute pain management.

A qualitative analysis of cancer-related patient care in the emergency department

OBJECTIVES

Due to an increasing incidence of new cancer diagnoses in the United States and longer survivorship, a growing number of patients with cancer receive care in emergency departments (EDs). This trend places an increasing burden on already crowded EDs, and experts are concerned these patients do not receive optimal care. The purpose of this study was to describe the experiences of ED physicians and nurses who care for patients with cancer. This information can inform strategies to improve oncology care for patients in ED settings.

METHODS

We used a qualitative descriptive design to summarize to the experiences of ED physicians and nurses (n = 23) caring for patients with cancer. We conducted individual, semistructured interviews to query participants about their perspectives on care for oncology patients in the ED.

RESULTS

Physician and nurse participants identified 11 challenges and suggested three potential strategies to improve care. The challenges included the following: risk of infection, poor communication between ED staff and other providers, poor communication between oncology or primary care providers and patients, poor communication between ED providers and patients, difficult disposition decisions, new cancer diagnoses, complex pain management, allocation of limited resources, lack of cancer-specific skills among providers, poor care coordination, and evolving end-of-life decisions. The solutions included the following: patient education, education for ED providers, and improved care coordination.

CONCLUSIONS

Physicians and nurses experience challenges stemming from three overarching types of factors: illness factors, communication factors, and system-level factors. Solutions for the challenges of providing oncology care in the ED call for new strategies at the levels of the patient, provider, institution, and health care system.

Potentially Avoidable Admissions and Prolonged Hospitalization in Patients with Suspected Colon Cancer

BACKGROUND

Suspicion of cancer in the Emergency Department (ED) may lead to potentially avoidable and prolonged admissions. We aimed to examine the reasons for potentially avoidable and prolonged hospitalizations after admissions from the ED for new colon cancer diagnoses (ED-dx).

METHODS

A retrospective, single-institution analysis was conducted of patients with ED-dx between 2017 and 2018. Defined criteria were used to identify potentially avoidable admissions. Patients without avoidable admissions were examined for ideal length of stay (iLOS), using separate defined criteria. Prolonged length of stay (pLOS) was defined as actual length of stay (aLOS) being greater than 1 day longer than iLOS.

RESULTS

Of 97 patients with ED-dx, 12% had potentially avoidable admissions, most often (58%) for cancer workup. Very little difference in demographic, tumor characteristics, or symptoms were found, except patients with potentially avoidable admissions were more functional (Eastern Cooperative Oncology Group [ECOG] score 0-1: 83% vs. 46%; p = 0.049) and had longer symptom duration prior to ED presentation {24 days (interquartile range [IQR] 7-75) vs. 7 days (IQR 2-21)}. Among the 60 patients who had necessary admissions but did not require urgent intervention, 78% had pLOS, most often for non-urgent surgery (60%) and further oncologic workup. The median difference between iLOS and aLOS was 12 days (IQR 8-16) for pLOS.

CONCLUSIONS

Potentially avoidable admissions following Ed-dx were uncommon but were mostly for oncologic workup. Once admitted, the majority of patients had pLOS, most often for definitive surgery and further oncologic workup. This suggests a lack of systems to safely transition to outpatient cancer management.

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.

Evaluation of the Impact of the Urgent Cancer Care Clinic on Emergency Department Visits, Primary Care Clinician Visits, and Hospitalizations in Winnipeg, Manitoba

The urgent cancer care (UCC) clinic at CancerCare Manitoba (CCMB) opened in 2013 to provide care to individuals diagnosed with cancer and serious blood disorders experiencing complications from the underlying disorder or its treatment. This study examined the impact of the UCC clinic on other health care utilization in Winnipeg, Manitoba, Canada. An interrupted time series study design was used to compare the rates of emergency department (ED) visits, primary care clinician (PCC) visits, and hospitalizations from 1 January 2010 to 31 December 2015. Rates of ED visits were also stratified by ED location, severity, and cancer type. We found a 6% (95% CI 1.00-1.13, p-value = 0.0389) increase in PCC visits, a 7% (95% CI 0.99-1.15, p-value = 0.0737) increase in hospitalizations, a 4% (95% CI 0.86-1.08, p-value = 0.5053) decrease in the rate of ED visits, and a 3% (95% CI 0.92-1.17, p-value = 0.5778) increase in the rate of ED visits during the UCC clinic hours after the UCC clinic opened. The implementation of the UCC clinic had minimal impact on health care utilization. Future work should examine the impact of the UCC clinic on other aspects of healthcare utilization (e.g., number of tests ordered and time spent waiting in CCMB's main clinics) and patient quality of life and patient and health care provider experience.

Retrospective study of cancer patients' predictive factors of care in a large, Hungarian tertiary care centre

OBJECTIVES

To identify predictive factors of multiple emergency department (ED) visits, hospitalisation and potentially preventable ED visits made by patients with cancer in a Hungarian tertiary care centre.

DESIGN

Observational, retrospective study.

SETTING

A large, public tertiary hospital, in Somogy County, Hungary, with a level 3 emergency and trauma centre and a dedicated cancer centre.

PARTICIPANTS

Patients above 18 years with a cancer diagnosis (International Classification of Diseases, 10th Revision codes of C0000-C9670) who visited the ED in 2018, who had received their diagnosis of cancer within 5 years of their first ED visit in 2018 or received their diagnosis of cancer latest within the study year. Cases diagnosed with cancer at the ED (new cancer diagnosis-related ED visits) were also included, constituting 7.9% of visits.

PRIMARY OUTCOME MEASURES

Demographic and clinical characteristics were collected and the predictors of multiple (≥2) ED visits within the study year, admission to inpatient care following the ED visit (hospitalisation), potentially preventable ED visits and death within 36 months were determined.

RESULTS

2383 ED visits made by 1512 patients with cancer were registered. Predictive factors of multiple (≥2) ED visits were residing in a nursing home (OR 3.09, 95% CI 1.88 to 5.07) and prior hospice care (OR 1.87, 95% CI 1.05 to 3.31). Predictive factors for hospitalisation following an ED visit included a new cancer diagnosis-related visit (OR 1.86, 95% CI 1.30 to 2.66) and complaint of dyspnoea (OR 1.61, 95% CI 1.22 to 2.12).

CONCLUSIONS

Being a resident of a nursing home and receiving prior hospice care significantly increased the odds of multiple ED visits, while new cancer-related ED visits independently increased the odds of hospitalisation of patients with cancer. This is the first study to report these associations from a Central-Eastern European country. Our study may shed light on the specific challenges of EDs in general and particularly faced by countries in the region.

Reducing Avoidable Emergency Visits and Hospitalizations With Patient Risk-Based Prescriptive Analytics: A Quality Improvement Project at an Oncology Care Model Practice

PURPOSE

Cancer-related emergency department (ED) visits and hospitalizations that would have been appropriately managed in the outpatient setting are avoidable and detrimental to patients and health systems. This quality improvement (QI) project aimed to leverage patient risk-based prescriptive analytics at a community oncology practice to reduce avoidable acute care use (ACU).

METHODS

Using the Plan-Do-Study-Act (PDSA) methodology, we implemented the Jvion Care Optimization and Recommendation Enhancement augmented intelligence (AI) tool at an Oncology Care Model (OCM) practice, the Center for Cancer and Blood Disorders practice. We applied continuous machine learning to predict risk of preventable harm (avoidable ACU) and generated patient-specific recommendations that nurses implemented to avert it.

RESULTS

Patient-centric interventions included medication/dosage changes, laboratory tests/imaging, physical/occupational/psychologic therapy referral, palliative care/hospice referral, and surveillance/observation. Nurses contacted patients every 1-2 weeks after initial outreach to assess and maintain adherence to recommended interventions. Per 100 unique OCM patients, monthly ED visits dropped from 13.7 to 11.5 (18%), a sustained month-over-month improvement. Quarterly admissions dropped from 19.5 to 17.1 (13%), a sustained quarter-over-quarter improvement. Overall, the practice realized potential annual savings of $2.8 million US dollars (USD) on avoidable ACU.

CONCLUSION

The AI tool has enabled nurse case managers to identify and resolve critical clinical issues and reduce avoidable ACU. Effects on outcomes can be inferred from the reduction; targeting short-term interventions toward patients most at-risk translates to better long-term care and outcomes. QI projects involving predictive modeling of patient risk, prescriptive analytics, and nurse outreach may reduce ACU.

Cardiovascular Reasons for Access to a Tertiary Oncological Emergency Service: The CARILLON Study

BACKGROUND

The prevalence of acute cardiovascular diseases (CVDs) in cancer patients is steadily increasing and represents a significant reason for admission to the emergency department (ED).

METHODS

We conducted a prospective observational study, enrolling consecutive patients with cancer presenting to a tertiary oncological ED and consequently admitted to the oncology ward. Two groups of patients were identified based on main symptoms that lead to ED presentation: symptoms potentially related to CVD vs. symptoms potentially not related to CVD. The aims of the study were to describe the prevalence of symptoms potentially related to CVD in this specific setting and to evaluate the prevalence of definite CV diagnoses at discharge. Secondary endpoints were new intercurrent in-hospital CV events occurrence, length of stay in the oncology ward, and mid-term mortality for all-cause.

RESULTS

A total of 469 patients (51.8% female, median age 68.0 [59.1-76.3]) were enrolled. One hundred and eighty-six out of 469 (39.7%) presented to the ED with symptoms potentially related to CVD. Baseline characteristics were substantially similar between the two study groups. A discharge diagnosis of CVD was confirmed in 24/186 (12.9%) patients presenting with symptoms potentially related to CVD and in no patients presenting without symptoms potentially related to CVD (p < 0.01). During a median follow-up of 3.4 (1.2-6.5) months, 204 (43.5%) patients died (incidence rate of 10.1 per 100 person/months). No differences were found between study groups in terms of all-cause mortality (hazard ratio [HR]: 0.85, 95% confidence interval [CI] 0.64-1.12), new in-hospital CV events (HR: 1.03, 95% CI 0.77-1.37), and length of stay (p = 0.57).

CONCLUSIONS

In a contemporary cohort of cancer patients presenting to a tertiary oncological ED and admitted to an oncology ward, symptoms potentially related to CVD were present in around 40% of patients, but only a minority were actually diagnosed with an acute CVD.

Trends and Characteristics of Potentially Preventable Emergency Department Visits Among Patients With Cancer in the US

IMPORTANCE

An initial step to reducing emergency department (ED) visits among patients with cancer is to identify the characteristics of patients visiting the ED and examine which of those visits could be prevented.

OBJECTIVE

To explore nationwide trends and characteristics of ED visits and examine factors associated with potentially preventable ED visits and unplanned hospitalizations among patients with cancer in the US.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study used data on ED visits from the National Hospital Ambulatory Medical Care Survey from January 1, 2012, to December 31, 2019; US Cancer Statistics reports were used to estimate new cancer cases each year. Frequencies and trends among 35 510 014 ED visits by adult patients (aged ≥18 years) with cancer were calculated.

MAIN OUTCOMES AND MEASURES

The primary outcome was potentially preventable ED visits, and secondary outcomes were unplanned hospitalizations and the immediacy of the ED visits. Potentially preventable ED visits were identified using the Centers for Medicare & Medicaid Services definition. The Emergency Severity Index, a triage algorithm that ranks patients based on the urgency of their health care condition, was used to measure the immediacy of ED visits (immediate [most urgent], emergent, urgent, less urgent, and nonurgent), with the categories of immediate and emergent classified as high acuity. The Wilcoxon rank sum test was used to calculate trends in ED visits among patients with cancer over time. Multivariable logistic regression analyses were performed to examine the associations of patient, hospital, and temporal factors with potentially preventable ED use and ED use resulting in hospitalization.

RESULTS

Among 854 911 106 ED visits, 35 510 014 (4.2%) were made by patients with cancer (mean [SD] age, 66.2 [16.2] years); of those, 55.2% of visits were among women, 73.2% were among non-Hispanic White individuals, 89.8% were among patients living in a private residence, and 54.3% were among Medicare enrollees. A total of 18 316 373 ED visits (51.6%) were identified as potentially preventable, and 5 770 571 visits (21.3%) were classified as high acuity. From 2012 to 2019, potentially preventable ED visits increased from 1 851 692 to 3 214 276. Pain (36.9%) was the most common reason for potentially preventable ED visits. The number of patients who visited an ED because of pain increased from 1 192 197 in 2012 to 2 405 849 in 2019 (a 101.8% increase). Overall, 28.9% of ED visits resulted in unplanned hospitalizations, which did not change significantly over time (from 32.2% in 2012 to 26.6% in 2019; P = .78 for trend). Factors such as residence in a nursing home (odds ratio, 1.73; 95% CI, 1.25-2.41) were positively associated with having a potentially preventable ED visit, and factors such as the presence of more than 1 comorbidity (odds ratio, 1.82; 95% CI, 1.43-2.32) were positively associated with having an unplanned hospitalization.

CONCLUSIONS AND RELEVANCE

In this study, 51.6% of ED visits among patients with cancer were identified as potentially preventable, and the absolute number of potentially preventable ED visits increased substantially between 2012 and 2019. These findings highlight the need for cancer care programs to implement evidence-based interventions to better manage cancer treatment complications, such as uncontrolled pain, in outpatient and ambulatory settings.

Nurse-Administered Auricular Point Acupressure for Cancer-Related Pain

PURPOSE

The study aimed to (1) examine the feasibility of providing a training course on auricular point acupressure (APA) for clinical oncology nurses to integrate APA into real-world nursing care settings, and (2) examine the effectiveness of APA on cancer-related pain (CRP) under usual inpatient oncology ward conditions.

METHODS

This was a 2-phase feasibility study. Phase 1, an in-person, 8 hour training program was provided to oncology nurses. Phase 2, a prospective and feasibility study was conducted to evaluate the integration of APA into nursing care activities to manage CRP. Oncology patients were included if their pain was rated at ≥4 on a 0 to 10 numeric rating scale in the past 24 hours. Patients received 1 APA treatment administered by the nurses and were instructed to stimulate the points for 3 days. Study outcomes (pain intensity, fatigue, and sleep disturbance), pain medication use, and APA practice were measured by a phone survey daily.

RESULTS

Ten oncology nurses received APA training in phase 1. APA had been added to the hospital's electronic health records (EHRs) as a pain treatment. In phase 2, 33 oncology patients received APA treatment with a 100% adherence rate (pressing the seeds 3 times per day, 3 minutes per time based on the suggestion). The side effects of APA were minimal (~8%-12% felt tenderness on the ear). After 3 days of APA, patients reported 38% pain relief, 39% less fatigue, and 45% improvement in sleep disturbance; 24% reduced any type of pain medication use and 19% reduced opioid use (10 mg opioids using milligram morphine equivalent). The major barrier to integrating APA into routine nursing practice was time management (how to include APA in a daily workflow).

CONCLUSION

It is feasible to provide 8-hour training to oncology nurses for mastering APA skill and then integrating APA into their daily nursing care for patients with CRP. Based on the promising findings (decreased pain, improved fatigue and sleep disturbance, and less opioid use), the next step is to conduct a randomized clinical trial with a larger sample to confirm the efficacy of APA for oncology nurses to treat CRP in real-world practice.ClinicalTrial.gov identifier number: NCT04040140.

Machine Learning Model of Emergency Department Use for Patients Undergoing Treatment for Head and Neck Cancer Using Comprehensive Multifactor Electronic Health Records

PURPOSE

To use a hybrid method, combining statistical profiling, machine learning (ML), and clinical evaluation to predict emergency department (ED) visits among patients with head and neck cancer undergoing radiotherapy.

MATERIALS AND METHODS

Patients with head and neck cancer treated with radiation therapy from 2015 to 2019 were identified using electronic health record data. Records from 60 days before 90 days after treatment were analyzed. Statistical profiling and ML were used to create a predictive model for ED visits during or after radiation therapy. A comprehensive set of variables were studied. Multiple ML models were developed including extreme gradient-boosted decision tree and generalized logistic regression with comparison of multiple predictive performance metrics.

RESULTS

Of the 1,355 patients studied, 13% had an ED visit during or after treatment. Our hybrid methodology enabled evidence-based winnowing of candidate features from 141 to 11 with clinically applicable, evidence-based thresholds. Extreme gradient boosting had the highest area under the curve (0.81 ± 0.06) with a sensitivity of 0.89 ± 0.10 and exceeded generalized logistic regression (area under the curve 0.64 ± 0.02). Significant predictors of ED visits during treatment included increasingly complex opioid use, number of prior ED visits, tumor volume, rate of change of blood urea nitrogen, total bilirubin, body mass index, and distance from hospital.

CONCLUSION

Our approach combining bootstrapped statistical profiling and ML importance analysis supported integration of clinician input to identify a distilled set of phenotypical characteristics for developing ML models predicting which patients undergoing head and neck cancer radiation therapy were at risk for ED visits.

Advanced Practice Provider Model for Urgent Oncology Care

Inherent to the cancer disease trajectory are heightened risks for a plethora of comorbid diagnoses. As the treatment landscape for oncology therapeutics continues to rapidly advance, patients are living longer and potentially experiencing more symptoms requiring rapid assessment. Prompt assessment and intervention for cancer or cancer treatment-related symptoms is imperative to achieve patient comfort and obtain the best overall patient outcomes. Traditionally, these patients were frequently referred to the emergency department (ED) when same-day clinic appointments were not obtainable. In order to decrease ED utilization and provide same-day urgent care for oncology patients, the Abramson Cancer Center established an advanced practice provider-led Oncology Evaluation Center where cancer patients are able to receive same-day assessment, symptom relief, and ultimately prevent unnecessary ED visits.

Presentation Patterns and Outcomes in Patients with Colorectal Cancer Seeking the Emergency Department for Consultation

Background Patients with colorectal cancer may seek the emergency department for symptoms related to chemotherapy and radiotherapy side effects as well as those from the disease itself and from surgery complications.

Objectives To establish the epidemiological and clinical profile of colorectal cancer patients that look for consultations in the emergency department.

Methods Retrospective study of emergency room charts from colorectal cancer patients that consulted in a single oncological hospital for the period of 1 year.

Results Four hundred and forty-six consultations were identified (49.5% males and 50.5% females) with a mean age of 63 years and with advanced disease (most with tumor, node, metastases [TNM] stages III and IV). The most common complaint was abdominal pain (27.5%), followed by nausea (4.7%; more commonly seen in females with p = 0.03) and bladder symptoms (4.7%; more commonly seen in males, with p = 0.003). Infections (10.3%) and acute abdominal pain (9.1%) were the most frequent diagnoses. About 18% of them were admitted to the hospital and 80% were discharged home.

Conclusion The profile of patients with colorectal cancer seeking the emergency department comprises patients with advanced disease and a similar proportion of males and females. Symptom-driven complaints were the most frequent reason for consultations.

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.

Recognizing the emergency department’s role in oncologic care: a review of the literature on unplanned acute care

Background

The global prevalence of cancer is rapidly increasing and will increase the acute care needs of patients with cancer, including emergency department (ED) care. Patients with cancer present to the ED across the cancer care continuum from diagnosis through treatment, survivorship, and end-of-life. This article describes the characteristics and determinants of ED visits, as well as challenges in the effort to define preventable ED visits in this population.

Findings

The most recent population-based estimates suggest 4% of all ED visits are cancer-related and roughly two thirds of these ED visits result in hospitalization—a 4-fold higher ED hospitalization rate than the general population. Approximately 44% of cancer patients visit the ED within 1 year of diagnosis, and more often have repeat ED visits within a short time frame, though there is substantial variability across cancer types. Similar patterns of cancer-related ED use are observed internationally across a range of different national payment and health system settings. ED use for patients with cancer likely reflects a complex interaction of individual and contextual factors—including provider behavior, health system characteristics, and health policies—that warrants greater attention in the literature.

Conclusions

Given the amount and complexity of cancer care delivered in the emergency setting, future research is recommended to examine specific symptoms associated with cancer-related ED visits, the contextual determinants of ED use, and definitions of preventable ED use specific to patients with cancer.

Acute home-based care for patients with cancer to avoid, substitute, and follow emergency department visits: a conceptual framework using Porter’s Five Forces

Background

Patients with cancer constitute a large and increasing segment of patients who receive unscheduled hospital-based care due to treatment-related symptoms and disease progression. The initial hospital-based touchpoint for these unscheduled hospitalizations is often the emergency department. Traditional models of emergency department and inpatient hospital-based care are saturated and incapable of scaling to accommodate the future, increased needs projected for this population. New models of care are necessary to address this gap. Acute home-based care is a promising tool potentially providing patient-centric, efficient care to eligible patients.

Methods

We applied Porter’s Five Forces framework that addresses the bargaining power of buyers and suppliers, threat of substitutes and new entrants, and industry rivalries plus the sixth force of regulation to clarify the factors that will promote or challenge the adoption of a home-based cancer care referral model before or following emergency department visits. Exploring this framework provides insights into the complexities of scaling an acute home-based cancer care model and highlights ways for health systems including hospitals, emergency departments, physician groups, and individual emergency physicians and oncologists to optimize their roles in this emerging model of care.

Results

We found that current workforce shortages, as well as workflow, infrastructure, and regulatory complexities, pose major challenges that unless carefully addressed may restrict the growth of acute home-based cancer care. Additional uncertainties persist around appropriate payment models and the competitive landscape. Key promoting factors include the recognized need in the cancer community and among payers for new models to decrease unscheduled hospitalizations and emergency department visits as well as the uptake of home-based and technology-enabled solutions during the COVID-19 pandemic. A better understanding of these forces helps to clarify the risks and opportunities as new entrants build their programs.

Conclusions

Acute home-based cancer care is a promising tool to complement traditional outpatient clinics, emergency departments, and inpatient hospital-based models of cancer care. New technologies and policies increasingly enable a broader scope of cancer care in the home setting.

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.

A study of the factors associated with emergency department visits in advanced cancer patients receiving palliative care

Purpose

Several studies demonstrated that cancer patients visited the emergency department (ED) frequently. This indicates unmet needs and poor-quality palliative care. We aimed to investigate the factors that contribute to ED visits among patients with advanced cancer in order to identify strategies for reducing unnecessary ED visits among these patients.

Methods

A retrospective study was conducted between January and December, 2019. Eligible patients were previously enrolled in the comprehensive palliative care program prior to their ED visit. All patients older than 18 were included. Patients were excluded if they had died at the initial consultation, were referred to other programs at the initial consultation, or had an incomplete record. The trial ended when the patients died, were referred to other palliative programs, or the study ended. The time between the initial palliative consultation and study endpoints was categorized into three groups: 16 days, 16–100 days, and > 100 days, based on the literature review. To investigate the factors associated with ED visits, a logistic regression analysis was conducted. The variables with a P value < 0.15 from the univariate logistic regression analysis were included in the multiple logistic regression analysis.

Results

Among a total of 227 patients, 93 visited the ED and 134 did not. Mean age was 65.5 years. Most prevalent cancers were colorectal (18.5%), lung (16.3%), and hepatobiliary (11.9%). At the end, 146 patients died, 45 were alive, nine were referred to other programs, and 27 were lost to follow-up. In univariate logistic regression analysis, patients with > 100 days from palliative consultation (OR 0.23; 95%CI 0.08, 0.66; p-value 0.01) were less likely to attend the ED. In contrast, PPS 50–90% (OR 2.02; 95%CI 1.18, 3.47; p-value 0.01) increased the ED visits. In the multiple logistic regression analysis, these two factors remained associated with ED visits:> 100 days from the palliative consultation (OR 0.18; 95%CI 0.06, 0.55; p-value 0.01) and PPS 50–90% (OR 2.62; 95%CI 1.44, 4.79; p-value 0.01).

Conclusions

There was reduced ED utilization among cancer patients with > 100 days of palliative care. Patients having a lower PPS were associated with a lower risk of ED visits.

Reasons for Emergency Department Visit, Outcomes, and Associated Factors of Oncologic Patients at Emergency Department of Jimma University Medical Centre

INTRODUCTION

The number of oncologic patients visiting the emergency department (ED) is increasing and represent a challenge for the emergency team owing to they might have acute sign and symptoms of a still undiagnosed malignancy, management of treatment-related side effects, co-morbidities, and palliative care. Thus, this study was aimed to identify reasons for ED visits, management outcomes, and associated factors of oncologic patients.

PATIENTS AND METHODS

A prospective cross-sectional study was conducted from March 11, 2021 to August 25, 2021 at the ED of Jimma University Medical Center on a total of 338 oncologic patients. Data were collected from the patient and the patient's medical record using a questionnaire developed from up-to-date similar literatures. The questionnaire was started filled out upon diagnosis of cancer and completed during discharge from the ED. The outcomes of the patients were dichotomized into died and survived then, it was analyzed using frequency and bivariate logistic regression.

RESULTS

The most common reasons for oncologic patients ED visit were neutropenic fever 79 (23.4%) followed by vomiting 38 (11.2%) and electrolyte abnormality 37 (10.9%) respectively. Among oncologic patients visited ED, 137 (40.5%) of them were admitted to ward and 126 (37.3%) of them were discharged with improvement while 64 (18.9%) of them were died. Based on multivariate logistic regression, those patients who had distant metastasis cancer (AOR 1.85; 95% CI 1.03-7.21), comorbidity (AOR 2.56; 95% CI 1.20, 6.96), and ECOG >3 (AOR 2.40; 95% CI 1.25,13.43) were more likely to die than their counterparts.

CONCLUSION

Most of the oncologic patients visited ED due to neutropenic fever, nausea and or vomiting, and electrolyte disorder. Amongst oncologic patients who were visited ED, most of them were admitted to ward while around one-fifth of them were died. Having distant metastasis cancer, comorbidity and ECOG >3 were independent predictors of an oncologic patient's outcome at the ED.

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.

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.

Evaluating Cancer Pain Characteristics and Treatment Factors in the Emergency Department: A Retrospective Cohort Study

Objectives: To identify patient characteristics and treatment factors of patients presenting to the emergency department (ED) with cancer-related pain that may affect patient outcomes. Methods: We conducted a retrospective cohort study to evaluate adult patients with active cancer, who presented to the ED with a chief complaint of pain between June first, 2012 and January first, 2016. We utilized multivariable logistic regression to evaluate the association of several exposure variables, including disease and demographic characteristics, primary pain site, and treatment methods, on ED disposition and revisit rate. Results: We included 483 patients with active cancer with a chief complaint of pain. Patients with severe pain on arrival tended to be younger than those who did not present with severe pain (median: 58 vs 62 respectively, OR 8.0 p < 0.01). Patients with high ECOG scores (3-4) with severe pain on arrival (≥7 out of 10) had less improvement in their pain than the rest of our cohort (OR 8.4, p < 0.01). Also, those with musculoskeletal pain had significantly less improvement in reported pain than all other pain types (delta pain −2.1 vs −3.4, OR 2.3, p = 0.025) Long delays in initial analgesic administration were associated with increased rates of subsequent admission (OR 3.4) [p = 0.014]. Although opioid analgesics led to greater decreases in pain than non-opioid analgesics, patients treated with opioids were more likely to be admitted (43% vs 34.5% AOR 1.51, p = 0.048). Conclusion: Our study showed that delays in analgesic administration, poor functional status, and the presence of musculoskeletal (MSK) pain significantly influenced outcomes for this patient cohort. These findings suggest the development of specific protocols and tools to address cancer-related pain in the ED may be necessary.

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.

Risk factors and predictors of immune-related adverse events: implications for patients with non-small cell lung cancer

INTRODUCTION

Immune checkpoint inhibitors (ICI) are now utilized as a standard of care treatment for multiple cancers, including in both the metastatic setting as well as in earlier stages of disease. The identification of unique immune-related adverse events (irAE) that occur during ICI treatment has led to intense research to identify potential risk factors and biomarkers that may assist in clinical decision making. Although initial studies in ICI were primarily in advanced stage disease, the use of ICI in earlier stages of disease as adjuvant therapies requires a better understanding of patient risk stratification to mitigate or prevent serious irAE.

AREAS COVERED

In this review, we set out to describe the current state of research regarding potential risk factors for irAE in patients with non-small cell lung cancer, as well as explore the barriers to understanding irAE. We review data from irAE that occur in large phase 3 trials and prospective studies focusing on irAE, as well as the many retrospective studies that currently form the bulk of our understanding of irAE.

Palliative Care Needs and Clinical Outcomes of Patients with Advanced Cancer in the Emergency Department

Background: Older adults with cancer use the emergency department (ED) for acute concerns. Objectives: Characterize the palliative care needs and clinical outcomes of advanced cancer patients in the ED. Design: A planned secondary data analysis of the Comprehensive Oncologic Emergencies Research Network (CONCERN) data. Settings/Subjects: Cancer patients who presented to the 18 CONCERN affiliated EDs in the United States. Measurements: Survey included demographics, cancer type, functional status, symptom burden, palliative and hospice care enrollment, and advance directive code status. Results: Of the total (674/1075, 62.3%) patients had advanced cancer and most were White (78.6%) and female (50.3%); median age was 64 (interquartile range 54-71) years. A small proportion of them were receiving palliative (6.5% [95% confidence interval; CI 3.0-7.6]; p = 0.005) and hospice (1.3% [95% CI 1.0-3.2]; p = 0.52) care and had a higher 30-day mortality rate (8.3%, [95% CI 6.2-10.4]). Conclusions: Patients with advanced cancer continue to present to the ED despite recommendations for early delivery of palliative care.

Main reasons and predictive factors of cancer-related emergency department visits in a Hungarian tertiary care center

BACKGROUND

Identifying the reasons for the Emergency Department (ED) visit of patients with cancer would be essential for possibly decreasing the burden of ED use. The aim of our study was to analyze the distribution of the demographic and clinical parameters of patients with cancer based on the reasons for the ED visits and to identify possible predictive factors for their visits.

METHODS

This retrospective study, carried out at a large, public tertiary hospital in Hungary, involved all patients 18 years or over, who had received a cancer diagnosis latest within five years of their visit to the ED in 2018. Demographic and clinical characteristics were collected partly via automated data collection and partly through the manual chart review by a team of experts, including six emergency physicians and an oncologist. Five main reasons for the ED visit were hypothesized, pilot-tested, then identified, including those with cancer-related ED visits (whose visit was unambiguously related to their cancer illness) and those with non-cancer-related ED visits (whose visit to the ED was in no way associated with their cancer illness.) A descriptive approach was used for data analysis and binary logistic regression was used to determine predictive factors for patients with cancer visiting the ED.

RESULTS

23.2% of the altogether 2383 ED visits were directly cancer-related, and these patients had a significantly worse overall survival than patients with non-cancer related ED visits. Age 65 or below (Odds Ratio: 1.51), presence of two more comorbidities (OR: 7.14), dyspnea as chief complaint (OR: 1.52), respiratory cancer (OR: 3.37), any prior chemotherapy (OR: 1.8), any prior immune/biological treatment (OR: 2.21), any prior Best Supportive Care/palliative care (OR: 19.06), or any prior hospice care (OR: 9.43), and hospitalization (OR:2.88) were independent risk factors for the ED visit to be cancer-related.

CONCLUSIONS

Our study is the first to identify independent predictive factors of ED use by patients with cancer based on the chief cause of their visit in the Central and Eastern European region. These results may provide important information for the development of algorithms intended to identify the needs of care of patients with cancer at the ED.

Emergency department cardiovascular disease encounters and associated mortality in patients with cancer: A study of 20.6 million records from the USA

BACKGROUND

there is limited data on Emergency department (ED) cardiovascular disease (CVD) presentations and outcomes amongst cancer patients.

OBJECTIVES

The present study aimed to describe the clinical characteristics, prevalence, and clinical outcomes of the most common cardiovascular ED admissions in patients with cancer.

METHODS

All ED encounters with a primary CVD diagnosis from the US Nationwide Emergency Department Sample between January 2016 to December 2018 were stratified by cancer type as well as metastatic status. Multivariable logistic regression was performed to determine the adjusted odds ratios of in-hospital mortality in different groups.

RESULTS

From a total of 20,737,247 ED encounters with a primary CVD diagnosis, cancer was present in 3.4%. In patients with cancer the most common CVDs were DVT/PE (20%), hypertensive heart or kidney disease (14.7%), and AF/flutter (11.2%). The distribution of CVDs varied by cancer type, with AF/flutter most common in patients with lung cancer, AMI most common in patients with prostate cancer, heart failure most common in those with haematological malignancies, and patients with colorectal cancer having the greatest frequency of DVT/PE. Cancer status was independently associated with significantly higher risk of mortality in almost all CVD categories, consistent across all the cancer types, amongst which lung cancer patients had the highest risk of mortality across all CVD categories, except intracranial haemorrhage and hypertensive crisis.

CONCLUSIONS

Cardiovascular presentations to the ED varied by cancer subtype. Across all cancer subtypes, patients presenting with cardiovascular presentations carried a significantly increased risk of mortality compared to patients with no cancer.

Chief complaints of patients with cancer who visit the emergency department over their oncologist's outpatient clinic in South Korea

Background

There have been several reports of patients with cancer visiting the Emergency Department (ED) rather than the outpatient department of their oncologist. In this study, we aimed to analyze the chief complaints, visit time, and time spent in the ED between study groups of patients with cancer visiting the ED. This finding will help medical staff provide better care for patients with cancer and reduce time spent in the ED.

Methods

A total of 787 patients with cancer visited the Regional Emergency Medical Center between January 1, 2020, and December 31, 2020. After the exclusion criterion such as patients who were transferred to the ED with a referral issued slip, patients who were pregnant women or minors under the age of 18 were applied, data from 607 patients with cancer were collected retrospectively from electronic medical records at the hospital. The participating patients with cancer were divided into two groups: 1) ED group—those who were cared for by the ED physician and 2) Referral group—those who were referred to their oncologist for hospitalization.

Results

We found that 40% of the total patients with cancer included in the study visited the ED with a chief complaint of pain. It was observed that the highest frequency of visits to the ED was around noon during clinic hours. The length of ED stay was 169 and 566 min for the ED and referral groups, respectively.

Conclusion

It would be more beneficial for patients with cancer visiting the ED to be quickly discharged from the ED physician’s active care for their symptoms. This usage of ED services will reduce unnecessary waiting time.

Ovarian Neoplasm: Delivering Suspicion of Cancer in the Emergency Department

Cancer is not infrequently detected in the Emergency Department (ED) and is sometimes even an incidental finding on imaging. Since the ED is designed to identify and treat acutely ill patients, the time providers can spend with patients and the depth of investigation into patient conditions is limited. However, Emergency Medicine physicians must ensure the appropriate follow-up for patients with presumptive diagnosis of cancer to ensure timely confirmatory testing, prompt treatment, and accurate prognosis. A 26-year-old woman presented to the ED for evaluation of abdominal pain and urinary complaints and was ultimately found to have a 36cm ovarian mass that was suspicious for neoplasm. The mass caused obstruction of urinary outflow leading the patient to develop a urinary tract infection. Emergency Medicine physicians are faced with the challenge of having limited time and short-lived doctor-patient relationships. In cases of suspicious findings, balancing the urgency of follow-up without causing undue harm from heightened anxiety for patients is essential. It is important to discuss findings that may be concerning for cancer with both clear verbal and written communication. Employ strategies such as direct communication with primary care physicians and outpatient specialists via phone consultation and electronic medical record messaging, as well as providing clear discharge instructions in-person and in-writing to the patient including whom to call and the time frame for follow-up.

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.

Postoperative Rather Than Preoperative Neutropenia Is Associated With Early Catheter-related Bloodstream Infections in Newly Diagnosed Pediatric Cancer Patients

BACKGROUND

The relationship of early catheter-related bloodstream infections (CRBSIs) with perioperative neutropenia and antibiotic prophylaxis is not well established. We sought to evaluate perioperative factors associated with early CRBSIs in newly diagnosed pediatric cancer patients, particularly hematologic indices and antibiotic use.

METHODS

We retrospectively reviewed national registry records of newly diagnosed pediatric cancer patients with port-a-caths inserted using standardized perioperative protocols where only antibiotic use was not regulated. Thirty-day postoperative CRBSI incidence was correlated with preoperative factors using logistic regression and with postoperative blood counts using linear trend analysis.

RESULTS

Among 243 patients, 17 CRBSIs (7.0%) occurred at median 14 (range, 8-28) postoperative days. Early CRBSIs were significantly associated with cancer type [acute myeloid leukemia and other leukemias (AML/OLs) vs. solid tumors and lymphomas (STLs): odds ratio (OR), 5.09; P = 0.0036; acute lymphoblastic leukemia vs. STL: OR 0.83; P = 0.0446] but not preoperative antibiotics, absolute neutrophil counts and white blood cell counts. Thirty-day postoperative absolute neutrophil counts and white blood cell trends differed significantly between patients with acute lymphoblastic leukemia and STLs (OR 0.83, P < 0.05) and between AML/OLs and STLs (OR 5.09, P < 0.005), with AML/OL patients having the most protracted neutropenia during this period.

CONCLUSIONS

Contrary to common belief, low preoperative absolute neutrophil counts and lack of preoperative antibiotics were not associated with higher early CRBSI rates. Instead, AML/OL patients, particularly those with prolonged neutropenia during the first 30 postoperative days, were at increased risk. Our findings do not support the use of empirical preoperative antibiotics and instead identify prolonged postoperative neutropenia as a major contributing factor for early CRBSI.

Increased Emergency Department Utilization and Costs for Medicare Cancer Patients with Malnutrition Diagnoses

BACKGROUND

Malnutrition or its risk affects up to 70% of cancer patients. Compared to adequately nourished oncology patients, those with malnutrition experience more complications and have poorer prognoses, thus higher needs for healthcare. We compared utilization of emergency department (ED) services and costs for Medicare-covered cancer patients with or without a malnutrition diagnosis.

METHODS

We used the Centers for Medicare and Medicaid Services (CMS) Standard Analytic File to identify fee-for-service beneficiaries who had a cancer diagnosis, and had one or more outpatient claims in 2018. We totaled individual claims and costs for ED visits per beneficiary, then calculated mean per-person claims and costs for malnourished vs non-malnourished patients.

RESULTS

Using data from over 2.8 million claims of patients with cancer diagnoses, the prevalence of diagnosed malnutrition was 2.5%. The most common cancer types were genitourinary, hematologic/blood, and breast. Cancer patients with a malnutrition diagnosis, compared to those without, had a significantly higher annual total number of outpatient claims (21.4 vs. 11.5, P<.0001), including a 2.5-fold higher rate of ED visits (1.43 vs. 0.56, p<.0001). As result, such patients incurred more than 2-fold higher mean ED claim costs than did their adequately nourished counterparts ($10,724 vs. $4,935, P<.0001).

CONCLUSIONS

Our results suggest that malnutrition in cancer patients imposes a high outpatient burden on resource utilization and costs of care in terms of ED use. We propose that nutritional interventions can be used to improve health outcomes for people with cancer and to improve economic outcomes for patients and providers.

Characteristics of unplanned hospitalisations among cancer patients in Singapore

INTRODUCTION

Cancer is a pervasive global problem with significant healthcare utilisation and cost. Emergency departments (EDs) see large numbers of patients with oncologic emergencies and act as "gate-keepers" to subsequent hospital admissions. A proportion of such hospital admissions are rapidly discharged within 2 days and may be potentially avoidable.

METHODS

Over a 6-month period, we conducted a retrospective audit of active cancer patients presenting to the ED with subsequent admission to the Department of Medical Oncology. Our aims were to identify independent factors associated with a length of stay ≤2 days; and characterise the clinical and resource needs of these short admissions.

RESULTS

Among all medical oncology admissions, 24.4% were discharged within 2 days. Compared to longer stayers, patients with short admissions were significantly younger (P=0.010), had lower National Early Warning Scores (NEWS) (P=0.006), and had a lower proportion of gastrointestinal and hepatobiliary cancers (P=0.005). Among short admissions, common presenting medical problems were infections (n=144, 36.3%), pain (n=116, 29.2%), gastrointestinal complaints (n=85, 21.4%) and respiratory complaints (n=76, 19.1%). These admissions required investigations and treatments already available at the ED.

CONCLUSION

Short admissions have low resource needs and may be managed in the ED. This may help save valuable inpatient bed-days and reduce overall healthcare costs.

Impact of malignancy on In-hospital mortality, stratified by the cause of admission: An analysis of 67 million patients from the National Inpatient Sample

OBJECTIVE

To describe the patient characteristics and the reason for admission of patients with malignancy by malignancy, and to study mortality rates for the different causes of admissions among the different types of cancer.

PATIENTS AND METHODS

Using the nationwide Inpatient Sampling (2015-2017) we examined the cause of admission and associated in-hospital mortality, stratified by presence and type of malignancy. Multivariable logistic regression models were used to examine the association between in-hospital mortality and malignancy sites for different primary admission causes.

RESULTS

Out of 67 819 693 inpatient admissions, 8.8% had malignancy. Amongst those with malignancy, haematological malignancy was the most common (20.2%). The most common cause of admission amongst all cancers were malignancy-related admissions, where up to 57% of all colorectal admissions were malignancy-related. The most common non-malignancy cause of admission was infectious causes, which were most frequent among patients with haematological malignancy (18.4%). Patients with malignancy had higher crude mortality rates (5.7% vs 1.9%). Mortality rates were highest among patients with lung cancer (8.7%). Among all admissions, the adjusted rates of mortality were higher for patients with lung (OR 3.65, 95% CI [3.59-3.71]), breast (OR 2.06, 95% CI [1.99-2.13]), haematological (OR 1.79, 95% CI [1.76-1.82]) and colorectal (OR 1.71, 95% CI [1.66-1.76]) malignancies compared with patients with no malignancy.

CONCLUSION

Our work highlights the need to consider the burden of cancer on our hospital services and consider how the prognostic impact of different types of admissions may relate to the type of cancer diagnosis and understand whether these differences relate to disparities in clinical care/treatments.

Emergency department disposition of non-neutropenic febrile patients with cancer

OBJECTIVES

National data reveal that 60% of the 4.5 million annual emergency department (ED) visits by patients with cancer result in admission. Many of these visits are due to a febrile illness. Current literature provides limited guidance on how to treat non-neutropenic febrile ED patients. This study characterizes clinical outcomes of non-neutropenic febrile patients with cancer presenting to an academic, Comprehensive Cancer Center affiliated ED.

METHODS

Retrospective chart review of 101 randomly selected adult patients with active cancer presenting with a chief complaint of fever or a documented fever in the ED and an absolute neutrophil count above 1000 between October 2015 and September 2016. Descriptive statistics were calculated.

RESULTS

The primary malignancies represented were hematologic (24%), gastrointestinal (13%), head and neck (13%), and genitourinary (8%). Sixty-two percent were on chemotherapy, 15% on radiation therapy, and 12% were on targeted therapy. Severe illness outcomes occurred in 39% and 83% were admitted with a median length of stay of 4 days. Among admitted patients, 24% experienced a length of stay ≤2 days. A return visit to the ED or an in-system hospitalization within 7 days of the index visit occurred in 10% and death occurred within 7 days of the index visit in 4%.

CONCLUSION

A majority of patients presenting to the ED with non-neutropenic fever are admitted (83%), of whom nearly a quarter experience a length of stay of ≤2 days with infrequent serious illness outcomes. Future efforts should focus on the development of risk stratification tools in this population to avoid potentially unnecessary hospitalizations.

Emergency Department Utilization of Adult Cancer Patient in Korea: A Nationwide Population-Based Study, 2017-2019

Purpose

The current study aimed to identify the overall characteristics of cancer-related emergency department (ED) visits by adult in Korea, including analyses of factors associated with ED stay time and outcomes nationwide.

Materials and Methods

We collected data on cancer-related ED visits from the National Emergency Department Information System (NEDIS) database between 2017 and 2019.

Results

ED visits by cancer patients comprised 5.5% (667,935 visits) of total ED visits from 2017 to 2019, which was slightly higher than in other counties. Patients with cancer who visited the ED were over 50 years old, the majority being males, and patients with cancer visited EDs in certified tertiary hospitals more frequently than patients without cancer. In multivariate analyses, the adjusted odds ratio for a length of stay more than 8 hours in the ED of certified tertiary hospitals was 126.34 (95% confidence interval, 1.422 to 1.460) when compared to hospitals. Nevertheless, the longer the patients stayed in the ED, the more likely they were to be admitted.

Conclusion

The longer ED stay and higher proportion of cancer patient hospitalizations suggest that cancer patients visit ED to be admitted as well as to receive acute care. The frequency of ED visits and admission may be adjusted to some extent depending on outpatient education, such as self-management of symptoms and situations. Improving cancer care in local communities should be met though provisions such as linking treatment between hospitals or supplying appropriate medical personnel, even for the efficient use of ED resources in hospitals.

Impact of COVID-19 lockdown on routine oncology versus emergency care at a high volume cancer centre

BACKGROUND

We investigated the influence of population-wide COVID-19 lockdown measures implemented on 16, March 2020 on routine and emergency care of cancer outpatients at a tertiary care cancer centre in Vienna, Austria.

METHODS

We compared the number/visits of cancer outpatients receiving oncological therapies at the oncologic day clinic (DC) and admissions at the emergency department (ED) of our institution in time periods before (pre-lockdown period: 1 January - 15 March 2020) and after (post-lockdown period: 16 March- 31 May 2020) lockdown implementation with the respective reference periods of 2018 and 2019. Additionally, we analysed Emergency Severity Index (ESI) score of unplanned cancer patient presentations to the ED in the same post-lockdown time periods. Patient outcome was described as 3-month mortality rate (3-MM).

RESULTS

In total, 16 703 visits at the DC and 2664 patient visits for the respective time periods were recorded at the ED. No decrease in patient visits was observed at the DC after lockdown implementation (P = .351), whereas a substantial decrease in patient visits at the ED was seen (P < .001). This translates into a 26%-31% reduction of cancer-related patient visits per half month after the lockdown at the ED (P < .001 vs. 2018 + 2019). There was no difference in the distribution of ESI scores at ED presentation (P = .805), admission rates or 3-MM in association with lockdown implementation (P = .086).

CONCLUSION

We demonstrate the feasibility of maintaining antineoplastic therapy administration during the COVID-19 pandemic. However, our data underline the need for adapted management strategies for emergency presentations of cancer patients.
