A prospective study of patients with low back pain attending a Canadian emergency department: Why they came and what happened?

Low back pain is a common presentation to emergency departments, but the reasons why people choose to attend the emergency department have not been explored. We aimed to fill this gap with this study to understand why persons with low back pain choose to attend the emergency department. Between July 4, 2017 and October 1, 2018, consecutive patients with a complaint of low back pain presenting to the University of Alberta Hospital emergency department were screened. Those enrolled completed a 13-item questionnaire to assess reasons and expectations related to their presentation. Demographics, acuity and disposition were obtained electronically. Factors associated with admission were examined in a logistic regression model. After screening 812 patients, 209 participants met the study criteria. The most common Canadian Triage and Acuity Scale score was 3 (73.2%). Overall, 37 (17.7%) received at least one consultation, 89.0% of participants were discharged home, 9.6% were admitted and 1.4% were transferred. Participants had a median pain intensity of 8/10 and a median daily functioning of 3/10. When asked, 64.6% attended for pain control while 44.5% stated ease of access. Most participants expected to obtain pain medication (67%) and advice (56%). Few attended because of cost savings (3.8%). After adjustment, only advanced age and ambulance arrival were significantly associated with admission. In conclusion, most low back pain patients came to the emergency department for pain control yet few were admitted and the majority did not receive a consultation. Timely alternatives for management of low back pain in the emergency department appear needed, yet are lacking.

Screening tools to identify patients with unmet palliative care needs in the emergency department: A systematic review.

OBJECTIVES: This systematic review identified and assessed psychometric properties of the available screening tools to identify patients with unmet palliative care (PC) needs in the emergency department (ED). METHODS: A comprehensive search of electronic databases and the gray literature was conducted. Two independent reviewers completed study screening and inclusion, data extraction, and quality assessment. A descriptive summary of the results was reported using median of medians and interquartile ranges (IQRs). RESULTS: A total of 35 studies were included, involving the assessment of 14 unique screening tools. The most commonly used screening tool was the surprise question (SQ; n = 12 studies), followed by the Palliative Care and Rapid Emergency Screening (P-CaRES) tool (n = 8), and the screening for palliative and end-of-life care needs in the emergency department (SPEED) instrument (n = 4). Twelve of the included studies reported on the psychometric properties of the screening tools, of which eight of these studies assessed the performance of the SQ to predict patient mortality. Overall, the median sensitivity (63%, IQR 38%-78%) and specificity (75%, IQR 57%-84%) of the SQ to predict mortality at 1 or 12 months was moderate. While the median positive predictive value of the SQ was low (32%, IQR 16%-40%), the median negative predictive value was high (91%, IQR 88%-95%). Across the studies, the proportion of patients identified as having unmet PC based on the criteria of the screening tools ranged from 5% to 83%. CONCLUSIONS: This review identified 14 unique screening tools used to identify adult patients with unmet PC needs in the ED. One screening tool, the SQ, was found to have moderate sensitivity and specificity to accurately predict future patient mortality. Additional research is needed to better understand the clinical value of this and the other available tools prior to their widespread implementation.

Comparison of the Management and Short-Term Outcomes between Patients with Advanced Cancer and Other End-of-Life Conditions Presenting to Two Canadian Emergency Departments.

Background: An increasing number of patients with end-of-life (EOL) conditions, particularly those with advanced cancer, are presenting to the emergency department (ED). Objectives: To assess the characteristics, management and short-term outcomes of ED patients with advanced cancer compared to patients with other EOL conditions. Methodology/Design: A secondary analysis of a prospective cohort study. Setting/Participants: Volunteer emergency physicians in two Canadian EDs identified presentations for advanced cancer and other EOL conditions with the aid of a modified screening tool March-August 2018. Results: Among the 663 presentations by patients with EOL conditions, 272 (41%) presented with advanced cancer. The majority of presentations for advanced cancer (81%) or other EOL conditions (77%) were by patients with unmet palliative care (PC) needs. Patients with advanced cancer were significantly less likely to have active goals of care (GOC) documented on their charts (53% vs. 75%; p < 0.001). While no significant differences were found between the groups, the majority of presentations involved imaging, investigations, consultations, and hospitalization. Presentations for advanced cancer were more likely to receive a postdischarge referral (38% vs. 23%; p < 0.001). Referrals to PC consultations or postdischarge referrals were infrequent. Regression analysis found that patients with advanced cancer were associated with shorter length of stay (LOS). Conclusions: The majority of presentations for advanced cancer or other EOL conditions involved significant resource use. Patients with cancer experienced shorter LOS; however, had less documentation of GOC and gaps in referrals to PC services were identified. Interventions should be explored to promote early GOC discussions and PC referrals in this patient group.

Comparison of characteristics and management of emergency department presentations between patients with met and unmet palliative care needs.

INTRODUCTION: This study examined emergency department (ED) presentations of patients with end of life (EOL) conditions and patients having met and unmet palliative care needs were compared. METHODS: Presentations for EOL conditions were prospectively identified and screened for palliative care needs. Descriptive data were reported as proportions, means or medians. Bi-variable analysis for dichotomous and continuous variables were performed by chi-squared and T-tests (p≤0.01), respectively. A multivariable logistic regression model identified factors associated with having unmet palliative needs and reported adjusted odds ratios (aOR) with 95% confidence intervals (CI). RESULTS: Overall, 663 presentations for EOL conditions were identified; 518 (78%) involved patients with unmet palliative care needs. Presentations by patients with unmet palliative needs were more likely to involve consultations (80% vs. 67%, p = 0.001) and result in hospitalization (69% vs. 51%, p<0.001) compared to patients whose palliative needs were met. Patients with unmet palliative care needs were more likely to have previous ED visits (73% unmet vs. 48% met; p<0.001). While medication, procedures, investigations and imaging ordering were high across all patients with EOL conditions, there were no significant differences between the groups. Consultations with palliative specialists in the ED (6% unmet vs. 1% met) and following discharge (29% unmet vs. 18% met) were similarly uncommon. Patients having two or more EOL conditions (aOR = 2.41; 95% CI: 1.16, 5.00), requiring hospitalization (aOR = 1.93; 95% CI: 1.30, 2.87), and dying during the ED visit (aOR = 2.15; 95% CI: 1.02, 4.53) were strongly associated with having unmet palliative care needs. CONCLUSIONS: Most ED presentations for EOL conditions were made by patients with unmet palliative care needs, who were significantly more likely to require consultation, hospitalization, and to die. Referrals to palliative care services during and after the ED visit were infrequent, indicating important opportunities to promote these services.

An Assessment of the Management of Patients with Advanced End-Stage Illness in the Emergency Department: An Observational Cohort Study.

Background: Presentations to the emergency department (ED) by patients with end-of-life (EOL) conditions for their acute care needs are common. Objectives: The objective of this study was to identify and describe the ED management across presentations to the ED for EOL conditions. Design: Prospective observational cohort study. Settings/Subjects: Emergency physicians in two Canadian ED's were asked to identify presentations by adult patients with EOL conditions using a modified screening tool. Measurements: Patient characteristics and ED management for each presentation were collected through chart review by trained research assistants. Descriptive analyses were conducted as appropriate and bivariate comparisons of dichotomous and continuous variables were completed using χ2 tests and using t test or Wilcoxon rank-sum test, respectively. Results: Physicians identified 663 ED presentations for EOL conditions, with advanced cancer (41%), dementia (23%), and chronic obstructive pulmonary disease (16%) being the most common EOL conditions. The majority of presentations involved consultations (77%), hospitalization (65%), and numerous investigations (97%), including blood work (97%) and imaging (92%). The majority of patients with EOL conditions had a history of ED visits (68%). Using a modified screening tool, 78% of presentations involved patients with unmet palliative care needs, but only 1% of presentations involved a palliative consultation or admission to a palliative care unit. Conclusion: Presentations to the ED for EOL conditions involve significant ED resources; however, only a handful of patients are referred to palliative services. Patients with EOL conditions are appropriate targets for palliative services and community support outside the ED.

An Assessment of Emergency Department-Based Interventions for Patients with Advanced or End-Stage Illness: A Systematic Review.

Background and Objective: With the increase of visits among patients with end-of-life needs, palliative care (PC) interventions delivered in the emergency department (ED) have become increasingly important. The objective of this systematic review was to examine the effectiveness of ED-based PC interventions. Methods: A comprehensive search of the literature was conducted to identify any comparative studies assessing the effectiveness of ED-based PC interventions. Two independent reviewers completed study selection, quality assessment, and data extraction. Relative risks (RR) with 95% confidence intervals (CIs) were calculated using a random effects model and heterogeneity (I2) was reported. Results: A total of 18 unique studies were included. Two studies reported no difference in return visits to the ED (RR = 1.31; 95% CI: 0.73-2.35; I2 = 47%). Two randomized trials reported no difference in mortality (RR = 0.89; 95% CI: 0.71-1.13; I2 = 0%), while one cohort study reported an increased mortality among patients referred to PC in the ED (RR = 1.89; 95% CI: 1.58-2.27). Overall, six out of eight studies reported a decrease in hospital length of stay (LOS) among patients undergoing an ED-based PC intervention compared with usual care. Conclusions: While there is compelling evidence to suggest that ED-based PC interventions can reduce hospital LOS, the evidence for the impact of these interventions on other outcomes is less robust. More high-quality comparative studies are needed to better understand the overall impact of ED-based PC interventions on improving patient outcomes as well as improving throughput and other quality of service-related outcomes.
