Volume and Acuity of Emergency Department Visits Prior To and After COVID-19.

ABSTRACT: BACKGROUND:There are scant data regarding the change in volume and acuity of patients presenting to emergency departments (EDs) after Coronavirus Disease 2019 (COVID-19), compared with the pre-COVID-19 era. OBJECTIVE:To determine ED volumes and triage acuity prior to and after COVID-19. METHODS:We determined the volume of patients presenting to four large EDs affiliated with general, cardiac, cancer, and obstetrics hospitals, and the acuity of presenting illness (using the Canadian Triage Acuity Scale [CTAS]) for March and April 2020 and compared them with the same months in 2019 and January 2020. Together, these facilities see over 80% of the ED visits in Qatar. The first COVID-19 patient in Qatar was diagnosed on February 29, 2020. RESULTS:A total of 192,157 ED visits were recorded during the study period. There was a 20-43% overall drop in number of ED visits, with significant variability across hospitals. The Heart Hospital experienced the sharpest decline (33-89%), and the National Center for Cancer Care and Research experienced the least decline in volumes. The decline was observed across all CTAS levels, with the largest decline observed in individuals presenting with CTAS 1 and 2 (26-69% decline month by month). No increase in overall number of deaths or crude mortality rate was observed in the COVID-19 era, according to national statistics. CONCLUSIONS:Sharp declines in ED visits and the triage acuity seen in both general and specialty hospitals raise the concern that severely ill patients may not be seeking timely care, and a surge may be expected once current restrictions on movement are lifted.

Project description:BackgroundCanadian pediatric emergency department visits are increasing, with a disproportionate increase in low-acuity visits locally (33% of volume in 2008-09, 41% in 2011-12). We sought to understand: 1) presentation patterns and resource implications; 2) parents' perceptions and motivations; and 3) alternate health care options considered prior to presenting with low-acuity problems.MethodsWe conducted a prospective cohort study at our tertiary pediatric emergency department serving two provinces to explore differences between patients with and without a primary care provider. During four, 2-week study periods over 1 year, parents of low-acuity visits received an anonymous survey. Presentation times, interventions, diagnoses and dispositions were captured on a data collection form linked to the survey by study number.ResultsParents completed 2,443 surveys (74.1% response rate), with survey-data collection form pairs available for 2,146 visits. Overall, 89.7% of respondents had a primary care provider; 68% were family physicians. Surprisingly, 40% of visits occurred during weekday office hours and 27.3% occurred within 4 hours of symptom onset; 67.5% of those early presenters were for injuries. Few parents sought care from their primary care provider (25%), health information line (20.7%), or urgent care clinic (18.5%); 36% reported that they believed their child's problem required the emergency department. Forty-five percent required only a history, physical exam and reassurance; only 11% required an intervention not available in an office setting. Patients without a primary care provider were significantly more likely to present during weekday office hours (p = 0.003), have longer symptom duration (p<0.001), and not know of other options (p = 0.001).ConclusionsMany parents seek pediatric emergency department care for low-acuity problems despite their child having a primary care provider. Ensuring timely access to these providers may help reduce pediatric emergency department overuse. Educational initiatives should inform parents about low-acuity problems and where appropriate care can/should be accessed.

Project description:Background: Recent research has found a high rate of emergency department (ED) use after lower extremity arthroplasty; one study found a risk factor for ED presentation after lower extremity arthroplasty was presentation to the ED in the year prior to surgery. It is not known whether a similar association exists for total shoulder arthroplasty (TSA). Questions/Purposes: The goal of this study was to investigate the relationship between preoperative ED visits and postoperative ED visits after anatomic TSA. Methods: The 100% Medicare database was queried for patients who underwent anatomic TSA from 2005 to 2014. Emergency department visits within the year prior to the date of TSA were identified. Patients were additionally stratified by the number and timing of preoperative ED visits. The primary outcome measure was one or more postoperative ED visits within 90 days. A multivariate logistic regression analysis was used to control for patient demographics and comorbidities. Results: Of the 144,338 patients identified, 32,948 (22.8%) had an ED visit in the year prior to surgery. Patients with at least 1 ED visit in the year before surgery presented to the ED at a significantly higher rate than patients without preoperative ED visits (16% versus 6%). An ED visit in the year prior to TSA was the most significant risk factor for postoperative ED visits (in the multivariate analysis). The number of preoperative ED visits in the year prior to surgery demonstrated a significant dose-response relationship with increasing risk of postoperative ED visits. Conclusions: Postoperative ED visits occurred in nearly 10% of Medicare patients who underwent TSA in the period studied. More frequent presentation to the ED in the year prior to anatomic TSA was associated with increasing risk of postoperative ED visits. Future studies are needed to investigate the reasons for preoperative ED visits and if any modifiable risk factors are present to improve the ability to risk stratify and optimize patients for elective TSA.

Project description:ObjectiveTo characterize and validate the landscape of algorithms that use International Classification of Disease (ICD) codes to identify low-acuity emergency department (ED) visits.Data sourcesPublicly available ED data from the National Hospital Ambulatory Medical Care Survey (NHAMCS).Study designWe systematically searched for studies that specify algorithms consisting of ICD codes that identify preventable or low-acuity ED visits. We classified ED visits in NHAMCS according to these algorithms and compared agreements using the Jaccard index. We then evaluated the performance of each algorithm using positive predictive value (PPV) and sensitivity, with the reference group specified using low-acuity composite (LAC) criteria consisting of both triage and clinical components. In sensitivity analyses, we repeated our primary analysis using only triage or only clinical criteria for reference.Data collectionWe used the 2011-2017 NHAMCS data, totaling 163,576 observations before survey weighting and after dropping observations missing a primary diagnosis. We translated ICD-9 codes (years 2011-2015) to ICD-10 using a standard crosswalk.Principal findingsWe identified 15 papers with an original list of ICD codes used to identify preventable or low-acuity ED presentations. These papers were published between 1992 and 2020, cited an average of 310 (SD 360) times, and included 968 (SD 1175) codes. Pairwise Jaccard similarity indices (0 = no overlap, 1 = perfect congruence) ranged from 0.01 to 0.82, with mean 0.20 (SD 0.13). When validated against the LAC reference group, the algorithms had an average PPV of 0.308 (95% CI [0.253, 0.364]) and sensitivity of 0.183 (95% CI [0.111, 0.256]). Overall, 2.1% of visits identified as low acuity by the algorithms died prehospital or in the ED, or needed surgery, critical care, or cardiac catheterization.ConclusionsExisting algorithms that identify low-acuity ED visits lack congruence and are imperfect predictors of visit acuity.
