5 Sickle Cell Disease in the Emergency Department, Predictors of Adverse Outcomes: A Prospective Cohort Study

Introduction: Hyperglycemic emergencies, including diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS), carry significant morbidity for individuals even after discharge. The objective of this study was to describe the patient-important outcomes and burden of disease for emergency department (ED) patients with hyperglycemia after discharge from hospital. Methods: This was a prospective cohort study of patients 18 years presenting to two tertiary care EDs (combined annual census 150,000 visits) with a discharge diagnosis of hyperglycemia, DKA or HHS over a 15-month period (Jul 2016-Oct 2017). During the ED visit, consent was obtained for a telephone follow-up call to determine patient-important outcomes. Trained research personnel collected data from medical records and completed a 14 day telephone follow-up using a standardized questionnaire to determine medication changes, missed days of school or work, and repeat admissions or visits to a healthcare provider. Descriptive statistics were used where appropriate to summarize the data. Results: Thus far, 172 patients have been enrolled in our study. Mean (SD) age is 53.9 (19.3) years and 97 (56.4%) are male. 65 (37.8%) patients were admitted from their initial ED visit. Of the 125 patients (72.7%) providing post-discharge outcomes, 75 (60.0%) required an adjustment to their diabetes medications or insulin. 21 (16.8%) patients missed days of school or work for a median (IQR) duration of 3.5 (1.3, 7.0) days. 85 (68.0%) saw another healthcare provider within a 14 day period, 45 (36.0%) saw their family physician, and 34 (27.2%) saw an internist or endocrinologist. 9 (7.2%) were seen again in the ED, 5 of these patients required admission to hospital. There was one death that occurred within the follow-up period. Conclusion: This prospective study builds on our previous retrospective work and demonstrates that visits for hyperglycemia carry a significant burden of disease beyond what may be seen in a single ED encounter. Further research will attempt to identify the factors that may be predictive of adverse outcomes in hyperglycemic patients presenting to the ED.

Background: The number of older adults with complex medical comorbidities and functional impairment is increasing throughout the world. Frail older adults frequently attend the Emergency Department (ED) and are at increased risk of adverse outcomes following presentation. A number of screening tools exist that aim to screen older adults for frailty and identify those at risk of functional decline, unscheduled readmission, institutionalisation and mortality. We propose to determine the predictive accuracy of four commonly used screening tools, namely the Identification of Seniors at Risk Screening (ISAR), Clinical Frailty Scale (CFS), Program of Research to Integrate Services for the Maintenance of Autonomy (PRISMA 7) and InterRAI ED, to determine adverse events at 30 days and six months among older adults who present to the ED. Methods and analysis: This is a prospective cohort study where patients over the age of 65 will have four screening tools (ISAR, CFS, PRISMA 7, interRAI ED) performed by face-to-face interview with a research nurse during their index visit to one Irish ED. Older adults will be included if they are willing and able to provide written informed consent, have a Manchester Triage Category 2-5 and are resident in the hospital catchment area. Demographic information will be collected at the index visit. A telephone follow up will occur at 30 days and six months, completed by a research nurse who is blinded to the initial assessment. Outcome data will include mortality rates, ED re-attendance, hospital readmission, functional decline and institutionalisation. We will analyse the risk of adverse outcomes using multivariable logistic regression and we will report adjusted risk ratios (RR) with 95% CI. Dissemination: Study findings will be disseminated through publication in peer-reviewed journals and presentations at relevant academic and clinical conferences. National and International gerontology conferences will be targeted.
