Improving cancer pain management in the emergency department: An EMR-based solution.

12110 Background: Pain is common reason for patients with cancer to seek care in the emergency department (ED). Unfortunately, these patients frequently receive inadequate doses of pain medication, partially due to opioid reduction efforts in the ED, as well as opioid tolerance among those with chronic cancer pain. The purpose of this study was to investigate the effectiveness of an electronic medical record (EMR) based best practice advisory (BPA) at improving analgesic dosing for cancer patients in the ED. Methods: We performed a retrospective cohort study on cancer pain at two academic medical centers from 05/18/20 to 10/27/20. The BPA algorithm identified ED patients with cancer that were taking prescription opioids with a morphine equivalent daily dose (MEDD) of at least 100, as calculated by the EMR. If the ED provider ordered opioids for these patients, a BPA alert appeared with a recommended opioid dose based on the patient’s individual MEDD. This alert also included pre-set safety orders for O2 and end tidal CO2 monitoring as well as naloxone. We compared outcomes based on whether an ED provider accepted or cancelled the BPA recommendation. These outcomes included the change in opioid dose and ED disposition. Continuous variables were compared using the students t-test, while categorical variables were compared with the chi-squared test with an alpha of 0.05. Results: Our BPA identified 92 patients that met our criteria, representing 143 BPA alerts. The mean age was 52, 43.5% were female, 54.3% had metastatic disease, and 56.5% presented with a painful chief complaint. Of the ED providers that accepted the BPA, 57.5% increased their dose of opioid medication. BPA usage led to a 33.3% mean increase in medication dosage (p <.001). Patients that presented with a painful chief complaint, whose providers utilized the BPA were admitted at a rate of 60.5%, verses a 77.8% admission rate among those whose providers did not utilize the BPA (p <.01). No patients required an opioid reversal agent. Conclusions: Among cancer patients on chronic opioids presenting to the ED, use of an EMR-based BPA led to more appropriate opioid dosing without the need for opioid reversal agents, and was associated with an overall decrease in hospital admissions.

Ed Visits

Abstract Vaso-occlusive crises (VOC) are a common cause of emergency department (ED) visits for children with sickle cell disease (SCD). To better understand our patient population and compare with reports from other centers, we sought to describe the presentation, management, and disposition of children with VOC at our center’s ED. We also aimed to identify predictors of hospital admission. We retrospectively reviewed hospital records of all patients with SCD, age 8–19 years, who presented to our urban pediatric ED in 2003 with a chief complaint of pain. We identified all subjects diagnosed with VOC and not another cause of pain. We obtained the following data for each: SCD genotype; duration of VOC and treatment prior to ED presentation; the nature of analgesia and use of intravenous fluids (IVF) in the ED; hemoglobin (Hgb) concentration; and disposition (admitted, discharged, discharged with subsequent ED visit for same crisis). Categorical variables were evaluated by the χ2 and Fisher exact tests and continuous variables by the t-test. Odds ratios (OR) and 95% confidence intervals (CI) were calculated where appropriate. In 2003, there were 320 ED visits for patients with SCD and pain. Among these, there were 279 diagnoses of VOC in 105 individual patients: 45 had one visit, 25 two visits, and 16 ≥5 visits. Mean number of visits per patient was 2.7; 23 (22%) patients accounted for 145 (55%) visits. Homozygous sickle cell anemia (Hgb SS) was present in 73/105 patients, accounting for 222 (79%) ED visits. Overall admission rate was 179/279 (64%), with 167/179 admitted on their first visit and 12 on their return visit. Subjects with Hgb SS accounted for 147/179 (82%) admissions. Among those discharged who later returned to the ED during the same VOC, the admission rate was 86% (5 returned in 24 hours, 5 in 48 hours, 3 in 72 hours, and one 4 days later). Pre-ED home opioid use was reported in 75% of visits and was associated with increased likelihood of discharge (OR 1.63, CI 0.94–2.84, p=0.082). Duration of VOC before presentation did not significantly affect admission rate and averaged 53.2 hours for admitted patients and 49.7 hours for those discharged (p=0.689). Patients who received IVF in the ED (219/279; 79%) were less likely to be admitted (31% vs 56%, p<0.001). Hgb concentration was increased in 61%, decreased in 36% and unchanged in 3% of patients from steady-state values and was not associated with admission. After receiving 2 doses of morphine, 31 patients were discharged from the ED, while only 5 patients were discharged after receiving 3 or 4 doses of morphine. A departmental VOC protocol was followed for 25.4% of patients, with no impact on admission rate (p=0.290). In this retrospective analysis of a large series of pediatric sickle cell ED visits, patients presented later in their VOC, and admission rate was higher than previously reported. A small proportion of older patients with SCD accounted for most ED visits and hospitalizations. Hgb variation from steady-state was neither clinically significant nor predictive of admission or discharge. In contrast to previous studies, receiving IVF in the ED was associated with a greater likelihood of discharge. Home opioids prior to ED presentation seemed to decrease hospital admission. Adherence to our center’s VOC protocol did not appear to influence disposition from the ED.

e20509 Background: Low-molecular weight heparin (LMWH) is preferred over warfarin in patients with thromboembolic disease and active cancer, but no guidelines exist in hospice. Although warfarin may be less safe in hospice patients, hospices may prefer to provide warfarin due to lower cost and less invasiveness compared to LMWHs. We sought to identify disparities in the use of warfarin vs. LMWHs in cancer patients enrolled in hospice. Methods: We analyzed a dataset from a national pharmacy provider for more than 800 hospices. We identified patients with a terminal diagnosis of cancer who were enrolled and died in hospice in 2006 and who were prescribed warfarin or LMWH. Patient characteristics included age, gender, race, cancer diagnosis, length of hospice service, and number of comorbidities. For descriptive comparisons, the Kruskal-Wallis test was used for continuous variables, and the Chi-square test was used for categorical variables. Results: Of 54,764 patients with cancer admitted and deceased in 2006, 3874 (7.1%) were prescribed warfarin, and 1137 (2.1%) were prescribed LMWH. Patients prescribed warfarin (n=576) or enoxaparin (n=5) for treatment of atrial arrhythmias were excluded. The mean age was 70.6 years for warfarin and 64.8 years for LMWH (p<0.0001). The mean and median lengths of service, respectively, were 43.6 days and 23.0 days for warfarin and 35.0 and 18.0 days for LMWH, (p<0.0001). There were no differences for gender, and a higher proportion of white patients were prescribed warfarin. Patients prescribed warfarin had an average of 2.1 comorbid conditions, versus 1.6 conditions for LMWH (p<0.0001). Cancer diagnoses were significantly different between the two groups, with a higher proportion of patients with lung and prostate cancer taking warfarin. Conclusions: Patients prescribed warfarin were older, had more comorbidities, and a longer length of service than patients prescribed LMWHs. Further research is needed to determine the impact of anticoagulation on outcomes, especially cost and quality of life, for cancer patients in hospice. This study raises the need to establish guidelines for the appropriateness of anticoagulation in hospice patients with cancer. No significant financial relationships to disclose.

Introduction: Atrial fibrillation and flutter (AFF) are the most common arrhythmias managed in the emergency department (ED). Equipoise in cardioversion strategies for patients with recent onset AFF contributes to observed practice variation. Using administrative data, the objective of this study was to explore the pattern of practice and the comparative effectiveness (outcomes and costs) between Shock-First and Drug-Shock approaches in AFF. Methods: Adult patients >17 years of age with AFF from one academic Canadian hospital ED were eligible. Using administrative data linkage among the National Ambulatory Care Record System, provincial practitioner claims data repository and a local hospital pharmacy database, patients who received treatment with procainamide and/or electrical cardioversion for AFF were identified. Outcomes including disposition, length of stay, revisit within 72 hours and 30-days, and ED costs were analyzed over a seven-year period. Categorical variables are reported as percentages. Continuous variables are reported as median and interquartile range (IQR). Univariate and multivariate logistic regression analyses were completed and reported as odds ratios (OR) and 95% confidence intervals (CI). Results: Overall, 5,372 patients were identified with AFF; the median age was 70 years and 55% were male. The majority of patients had chronic or secondary AFF; however, in 1687 (31%) cardioversion options were employed for presumed were recent onset AFF. A Shock-First strategy was most common (1379 {82%}); 308 (18%) received a Drug-Shock approach. Discharge time was 33 minutes (95% CI: 4–63) longer in the Drug-Shock approach compared to the Shock-First approach. Hospital admissions were higher (OR = 2.33; 95% CI: 1.68, 3.24) and revisits within 30-days were lower (OR = 0.74; 95% CI: 0.54, 0.95) in the Drug-Shock group. The Shock-First strategy demonstrated marginally higher costs (median = $106 CND; 95% CI: $68.89, $144.40) in adjusted analyses. Conclusion: In patients with acute AFF, when cardioversion was attempted, a Shock-First strategy was employed 80% of the time and resulted in shorter ED length of stay and lower hospitalization; however, higher costs and ED revisits within 30-days were observed. Many factors, including physician and/or patient preferences, influence ED decision-making in patients with AFF and understanding the factors influencing these decisions requires further attention.

Abstract Purpose: To describe the experience of patients with cancer presenting to the emergency department (ED) with pain and to identify patient and treatment factors that may affect patient outcomes. Methods: We conducted a retrospective cohort study to evaluate adult patients with active cancer, who presented to one of two academic EDs with a chief complaint of pain between June 1st, 2012 and December 31st, 2015. Variables analyzed included disease and demographic characteristics, pain character, treatment methods, ED disposition, and revisit rate. We utilized multivariable logistic regression to evaluate the association of our exposure variables on ED disposition. 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 statuses (3-4) with severe pain on arrival (≥ 7 out of 10) had less improvement in their pain (OR 8.4, p<.01). Long delays in initial analgesic administration were associated with increased rates of subsequent admission (OR 3.4) [p = 0.14]. 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 =.048).Conclusion: Several factors appear to play a role in the effectiveness of ED cancer pain management including patient and treatment characteristics. We hope that these findings will inform future studies and best-practice initiatives targeting ED cancer pain.

The Impact

2034 Background: The benefits of supportive medicine (SM) for cancer patients include improved quality of life, increased patient satisfaction, improved symptom management, increased cost savings and improved survival rates. At one NCI-designated cancer center, all patients were screened for distress; those who screened positive or were directly referred by a provider were enrolled into our multi-disciplinary SM program. Here, we document the impact of the supportive medicine program on outcomes of emergency department (ED) visits, hospital readmission, and non-billable touchpoints associated with patient navigation and resource referrals. Methods: The program systematically screened for biopsychosocial distress utilizing the National Comprehensive Cancer Center Distress Thermometer (DT) and the Problem Checklist (PC) to identify practical, emotional, spiritual and physical issues. Patients were categorized into three types: screened and enrolled in the SM program, and screened and not enrolled in the SM program, or provider referral into the SM program. Data included patient’s age, number of hospital admissions, emergency department visits, and non-billable touchpoints at 90 and 180 days after the distress screening or referral. Descriptive data were analyzed with counts and percentages for categorical variables and summarized with mean and standard deviation for numerical variables. For investigation of the effects of time and patient type on the change in utilization rate, generalized estimation equations for Poisson regression were conducted for each outcome. Results: In all, 2,738 patients were included in the analysis. Patients who were referred from a provider tended to be younger (p < .01) and more likely to die within 90 days (p < .001). At 180 days, ED visits decreased 18% for patients referred to the SM program and 42% for patients screened into the SM program, compared to a 3% decrease in ED visits among those not enrolled in the SM program (p < .01). Similarly, hospital admissions decreased 34% for patients referred to and 39% screened into the SM program, compared to a 4% increase for patients not enrolled in the SM program (p < .01). Non-billable touchpoints increased among all types of patients. Conclusions: An SM program reduces hospital admissions and ED visits, therefore improving outcomes and potentially reducing the cost of care for cancer patients. Future research should link this data to claims data to definitely evaluate the impact of SM programs on cost.

ABSTRACTObjective:We sought to determine the degree and possible causes of variability in admission practices among individual emergency physicians (EPs) at 1 emergency department (ED) using a Canadian Emergency Department Triage Acuity Scale (CTAS)–matched ED patient population.Methods:We distributed a survey measuring attitudes and demographics to all EPs (n= 30) at a large regional hospital. Hospital admissions data from 1 calendar year were matched to individual EP survey results. Emergency physicians were ranked as “lower,” “average” or “higher” admitters and, using these categorical variables, the data set was analyzed for correlations and trends.Results:Overall, 97.0% of the EPs responded to the survey. Admissions by EPs ranged from 8.7% to 17.0%, (mean 12.52, standard deviation [SD] 2.21) of all patients seen. CTAS category–specific admission data demonstrated variability in the admission ranking of individual EPs. No EPs consistently performed at any 1 admission ranking across all CTAS categories. More years of emergency medicine experience was significantly correlated with higher admissions in the CTAS-2 ranking (r= 0.4,p< 0.05). Whether a physician worked full-time, part-time or as a locum was not associated with patterns of admission, nor was any particular postgraduate certification (e.g., CCFP, CCFP EM, FRCPC) or any of the surveyed attitudinal traits.Conclusion:Individual EPs' overall and CTAS-specific admissions varied substantially, and followed an approximately normal distribution curve. Emergency physicians with more years of experience had a statistically higher CTAS-2 admission rate; however, other variables, including postgraduate certification status, decision-related attitudes toward admission, and reported practices were not associated with admission proportions. Emergency physicians tend to have uniquely individual admission ranking profiles across all the CTAS categories.

Abstract Introduction Increasing old age and frailty is putting pressure on health services with 5–10% of patients attending the emergency department (ED) and 30% of patients in acute medical units classified as older and frail. National Health Service improvement mandates that by 2020 hospital trusts with type one EDs provide at least 70 hours of acute frailty service each week. Methodology A two-week pilot (Monday–Friday 8 am-5 pm) was undertaken, with a “Front Door Frailty Team” comprising a consultant, junior doctor, specialist nurse and pharmacist, with therapy input from the existing ED team. They were based in the ED seeing patients on arrival, referrals from the ED team and patients in the ED observation ward—opposed to the usual pathway of referral from the ED team to medical team. Data was captured using “Cerner” electronic healthcare records. A plan, do, study, act methodology was used throughout with daily debrief and huddle sessions. Results 95 patients were seen over two weeks. In the over 65 s, average time to be seen was 50 minutes quicker than the ED team over the same period, with reduced admission rate (25.7% vs 46.5%). The wait between decision to admit and departure was shortened by 119 minutes. Overall, this led to patients spending on average 133 minutes less in the ED. 64 patients were discharged, of which 44 had community follow-up (including 37.5% of 64 referred to acute elderly clinic and 25% to rapid response). 47 medications were stopped across 25 patients. Conclusion The pilot shows that introduction of an early comprehensive geriatric assessment in the ED can lead to patients being seen sooner, with more timely decisions over their care and reduction in hospital admissions. It allowed for greater provision of acute clinics and community services as well as prompt medication review and real time medication changes.

Increased Risk

e18618 Background: Cancer patients frequently utilize the Emergency Department (ED) for a variety of diagnoses, both related and unrelated to their cancer. Patients with cancer have unique risks related to their cancer and treatment which could influence ED-related outcomes. A better understanding of these risks could help improve risk-stratification for these patients and help inform future interventions. This study sought to define the increased risks cancer patients face for inpatient admission and hospital mortality among cancer patients presenting to the ED. Methods: From the National Emergency Department Sample (NEDS) we identified patients with and without a diagnosis of cancer presenting to the ED between 2016 and 2018. We used International Classification of Diseases, version 10 (ICD10-CM) codes to identify patients with cancer, and to identify patient’s presenting diagnosis. Multivariable mixed-effects logistic regression models assessed the influence of cancer diagnoses on two endpoints: hospital admission from the ED, and inpatient hospital mortality. Results: There were 340 million weighted ED visits, of which 8.3 million (2.3%) occurred in patients with a cancer diagnosis. Compared to non-cancer patients, patients with cancer had an increased risk of inpatient admission (64.7% vs. 14.8%; p < 0.0001) and hospital mortality (4.6% vs. 0.5%; p < 0.0001). Factors associated with both an increased risk of hospitalization and death included older age, male gender, lower income level, discharge quarter, and receipt of care in a teaching hospital. We identified the top 15 most common presenting diagnoses among cancer patients, and among each of these diagnoses, cancer patients had increased risks of hospitalization (odds ratio [OR] range 2.0-13.2; all p < 0.05) and death (OR range 2.1-14.4; all p < 0.05) compared to non-cancer patients with the same diagnosis. Within the cancer patient cohort, cancer site was the most robust individual predictor associated with risk of hospitalization or death, with highest risk among patients with metastatic cancer, liver and lung cancers compared to the reference group of prostate cancer patients. Conclusions: Cancer patients presenting to the ED have high risks for hospital admission and death when compared to patients without cancer. Cancer patients represent a distinct population and may benefit from cancer-specific risk stratification or focused interventions tailored to improve outcomes in the ED setting.

Introduction: Delirium is a common emergency department (ED) presentation in elderly patients. Urinary tract infection (UTI) investigation and treatment are often initiated in delirious patients in the absence of specific urinary symptoms, despite a paucity of evidence to support this practice. The purpose of this study is to describe the prevalence of UTI investigation, diagnosis and treatment in delirious elderly patients in the ED. Methods: We performed a retrospective chart review of elderly patients presenting to the ED at The Ottawa Hospital between January 15-July 30, 2018 with a chief complaint of confusion or similar. Exclusion criteria were pre-existing and current UTI diagnosis, Glasgow Coma Scale <13, current indwelling catheter or nephrostomy tube, transfers between hospitals, and leaving without being seen. The primary outcome was the proportion of patients for whom urine tests (urinalysis or culture) or antibiotic treatment were ordered. Secondary outcomes were associations between patient characteristics, rates of UTI investigation, and patient outcomes. Descriptive values were reported as proportions with exact binomial confidence intervals for categorical variables and means with standard deviations for continuous variables. Comparisons were conducted with Fischer's exact test for categorical variables and t-tests for continuous variables. Results: After analysis of 1039 encounters with 961 distinct patients, 499 encounters were included. Urine tests were conducted in 324 patients (64.9% [60.6-69.1]) and antibiotics were prescribed to 176 (35.2% [31.1-39.6]). Overall 57 patients (11.4% [8.8-14.5]) were diagnosed with UTI, of which only 12 (21.1% [11.4-33.9]) had any specific urinary symptom. For those patients who had no urinary symptoms or other obvious indication for antibiotics (n = 342), 199 (58.2% [52.8-63.5]) received urine tests and 62 (18.1% [14.2-22.6]) received antibiotics. Patients who received urine tests were older (82.4 ± 8.8 vs. 78.3 ± 8.4 years, p < 0.001) but did not differ in sex distribution from those than those who did not. Additionally, patients who received antibiotics were more likely to be admitted (OR = 2.6 [1.48-4.73]) and had higher mortality at 30 days (OR = 4.2 [1.35-12.91]) and 6 months (OR = 3.2 [1.33-7.84]) than those who did not. Conclusion: Delirious patient without urinary symptoms in the ED were frequently investigated and treated for UTI despite a lack of evidence regarding whether this practice is beneficial.

Introduction: Inhaled toxins from tobacco smoking, cannabis leaf smoking as well as vaping/e-cigarette products use are known causes of cardio-respiratory injury. While tobacco smoking has decreased among Canadian adults, there are now several other forms of legal inhalant products. While legal, the evidence of benefit and safety of vaping is limited. Of concern, cases of e-cigarette or vaping products use associated lung injury (EVALI) have been accumulating in the U.S. and now in Canada. Despite this, very little is known about the inhalation exposure of emergency department (ED) patients; this study was designed to explore lung health in the ED. Methods: We investigated the prevalence of exposure to vaping, tobacco and cannabis among patients presenting to a Canadian ED from July to November 2019. Ambulatory (CTAS 2 to 5), stable, adult (≥ 17 years) patients were prospectively identified and invited to complete a survey addressing factors related to lung health (previous diagnosis of respiratory conditions and respiratory symptoms at the ED presentation) and information on current exposure to vaping, tobacco and cannabis smoking. Categorical variables are reported as frequencies and percentages; continuous variables are reported as medians with interquartile range (IQR). The study was approved by the Health Research Ethics Board. Results: Overall, 1024 (71%) of 1433 eligible patients completed the survey. The median age was 43.5 (IQR: 29, 60), and 51% were female. A total of 351 (31%) participants reported having been previously diagnosed with ≥1 respiratory conditions, and 177 (17%) were visiting the ED as a result of ≥1 respiratory symptoms (e.g., cough, shortness of breath, wheezing). Daily tobacco smoking was reported by 190 (19%), and 83 (8%) reported using vaping/e-cigarette products. Cannabis use within 30 days was described by 80 (15%) respondents. Exposure to tobacco and vaping products was reported by 39 (4%) participants, 63 (6%) reported using tobacco in combination with cannabis smoking, and 3% reported combining vaping and cannabis use. Conclusion: Patients seeking care in the ED are exposed to a large quantity of inhaled toxins. Vaping products, considered the cause of the most recent epidemic of severe lung injury, are used in isolation and in combination with other smoking products in Canada. These exposures should be documented and may increase the risk of lung health injuries and exacerbations of chronic respiratory conditions.
