Emergency department use by patients who received chimeric antigen receptor T cell infusion therapy.

Background: Chimeric antigen receptor T cell infusion (CAR T) therapy has revolutionized the treatment of hematologic malignancies, but treatment-related toxicities are of concern. Understanding the timing and reasons for which patients present to the emergency department (ED) after CAR T therapy can assist with the early recognition and management of toxicities. Methods: A retrospective observational cohort study was conducted for patients who had undergone CAR T therapy in the past 6 months and visited the ED of The University of Texas MD Anderson Cancer Center between 04/01/2018 and 08/01/2022. The timing of presentation after CAR T product infusion, patient characteristics, and outcomes of the ED visit were examined. Survival analyses were conducted using Cox proportional hazards regression and Kaplan-Meier estimates. Results: During the period studied, there were 276 ED visits by 168 unique patients. Most patients had diffuse large B-cell lymphoma (103/168; 61.3%), multiple myeloma (21/168; 12.5%), or mantle cell lymphoma (16/168; 9.5%). Almost all 276 visits required urgent (60.5%) or emergent (37.7%) care, and 73.5% of visits led to admission to the hospital or observation unit. Fever was the most frequent presenting complaint, reported in 19.6% of the visits. The 30-day and 90-day mortality rates after the index ED visits were 17.0% and 32.2%, respectively. Patients who had their first ED visit >14 days after CAR T product infusion had significantly worse overall survival (multivariable hazard ratio 3.27; 95% confidence interval 1.29-8.27; P=0.012) than patients who first visited the ED within 14 days of CAR T product infusion. Conclusion: Cancer patients who receive CAR T therapy commonly visit the ED, and most are admitted and/or require urgent or emergent care. During early ED visits patients mainly present with constitutional symptoms such as fever and fatigue, and these early visits are associated with better overall survival.

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.

Aspirin use is associated with decreased inpatient mortality in patients with COVID-19: A meta-analysis.

Thromboembolism is a major cause of death in patients who suffer from COVID-19. Studies examining the effects of aspirin (ASA) on mortality relating to this phenomenon have showed conflicting results with varying degrees and certainties of evidence. We performed an aggregate data meta-analysis of fourteen studies encompassing 164,539 COVID-19 patients, which showed a reduced risk of in-hospital mortality associated with ASA use in eight studies that reported risk ratios (RR 0.90; 95 % CI 0.82-0.98; I2 = 27.33 %, P = 0.01), six studies that reported hazard ratios (HR 0.56; 95 % CI 0.41-0.76, P ≤ 0.01; I2 = 85.92 %) and pooled effect size (0.71; 95 % CI 0.59-0.85, P = 0.00, I2 = 91.51 %). The objective of this study is to report the association between low dose ASA and a reduced risk of in-hospital mortality in patients with COVID-19.

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.

PURPOSE: 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. METHODS: We performed a retrospective observational study that included all patients age 18 years and older who presented to our emergency department (ED) and were placed in the EDOU between March 1, 2019, and February 29, 2020. The patients' electronic medical records were queried for demographics, comorbidities, diagnosis at the time of placement in the EDOU, length of stay, disposition from the EDOU, ED return within 72 hours after discharge from the EDOU, and mortality outcomes at 14 and 30 days. RESULTS: A total of 2,461 visits were eligible for analysis. Cancer-related pain was the main reason for observation in more than one quarter of the visits. The median length of stay in the EDOU was approximately 23 hours, and 69.6% of the patients were discharged. The ED return rate for unscheduled visits at 72 hours was 1.9%. The 14- and 30-day mortality rates were significantly higher for patients who were admitted than for those who were discharged (14 days: 1.7% v 0.3%, P < .001; 30 days: 5.9% v 1.8%, P < .001). CONCLUSION: Our data suggest that placing patients with cancer in EDOUs is safe, reduces admissions, and reserves hospital resources for patients who can receive the most benefit without compromising care.

Effect of a Virtual Reality-Enhanced Exercise and Education Intervention on Patient Engagement and Learning in Cardiac Rehabilitation: Randomized Controlled Trial.

BACKGROUND: Cardiac rehabilitation (CR) is clinically proven to reduce morbidity and mortality; however, many eligible patients do not enroll in treatment. Furthermore, many enrolled patients do not complete their full course of treatment. This is greatly influenced by socioeconomic factors but is also because of patients' lack of understanding of the importance of their care and a lack of motivation to maintain attendance. OBJECTIVE: This study aims to explore the potential benefits of virtual reality (VR) walking trails within CR treatment, specifically with regard to patient knowledge retention, satisfaction with treatment, and the overall attendance of treatment sessions. METHODS: New CR patients were enrolled and randomized on a rolling basis to either the control group or intervention group. Intervention patients completed their time on the treadmill with VR walking trails, which included audio-recorded education, whereas control patients completed the standard of care therapy. Both groups were assisted by nursing staff for all treatment sessions. Primary outcomes were determined by assessing 6-minute walk test improvement. In addition, secondary outcomes of patients' cardiac knowledge and satisfaction were assessed via a computer-based questionnaire; patient adherence to the recommended number of sessions was also monitored. Cardiac knowledge assessment included a prerehabilitation education quiz, and the same quiz was repeated at patients' final visit and again at the 2-month follow-up. The satisfaction questionnaire was completed at the final visit. RESULTS: Between January 2018 and May 2019, 72 patients were enrolled-41 in the intervention group and 31 in the control group. On the basis of the results of the prerehabilitation and postrehabilitation 6-minute walk test, no significant differences were observed between the intervention and control groups (P=.64). No statistical differences were observed between groups in terms of education (P=.86) or satisfaction (P=.32) at any time point. The control group had statistically more favorable rates of attendance, as determined by the risk group comparison (P=.02) and the comparison of the rates for completing the minimum number of sessions (P=.046), but no correlation was observed between the study group and reasons for ending treatment. CONCLUSIONS: Although no improvements were seen in the VR intervention group over the control group, it is worth noting that limitations in the study design may have influenced these outcomes, not the medium itself. Furthermore, the qualitative information suggests that patients may have indeed enjoyed their experience with VR, even though quantitative satisfaction data did not capture this. Further considerations for how and when VR should be applied to CR are suggested in this paper. TRIAL REGISTRATION: ClinicalTrials.gov NCT03945201; https://clinicaltrials.gov/ct2/show/NCT03945201.

Classification of Depression, Cognitive Disorders, and Co-Morbid Depression and Cognitive Disorders with Perfusion SPECT Neuroimaging.

BACKGROUND: Depression and cognitive disorders (CDs) are two common co-morbid afflictions that commonly present with overlapping symptoms. OBJECTIVE: To evaluate if perfusion neuroimaging with brain SPECT can distinguish persons with depression from those with CDs or both conditions. METHODS: Inclusion criteria were DSM-IV defined depression or CDs (Alzheimer's disease, vascular dementia, dementia not otherwise specified, and amnestic disorders not otherwise specified) including persons with both (total n = 4,541; 847 CDs, 3,269 depression, 425 with both). Perfusion differences between the groups were calculated using two-sampled t-tests corrected for multiple comparisons. Diagnostic separation was determined with discriminant analysis. Feature selection revealed predictive regions in delineating depression from CDs and comorbid cases. RESULTS: Persons with CDs had lower cerebral perfusion compared to depression. In co-morbid persons, cerebral hypoperfusion was additive, with regions showing lower regional cerebral blood flow compared to either diagnosis alone. Both baseline and concentration SPECT regions yielded correct classification of 86% and leave one out cross-validation of 83%. AUC analysis for SPECT regions showed 86% accuracy, 80% sensitivity and 75% specificity. Discriminant analysis separated depression and CDs from comorbid cases with correct classification of 90.8% and cross validated accuracy of 88.6%. Area under the curve was 83% with sensitivity of 80% and specificity of 70%. Feature selection identified the most predictive regions in left hippocampus, right insula, cerebellar, and frontal lobe regions. CONCLUSION: Quantitative perfusion SPECT neuroimaging distinguishes depression from dementia and those with both co-morbidities. Perfusion brain SPECT can be utilized clinically to delineate between these two disorders.
