Impact of extreme temperatures on emergency department visits: A multicenter study in Catalonia (2020-2025).

130 Meeting established canadian benchmarks for access to heart failure (HF) care following emergency department visit and association with outcome

Healthcare utilization for patients with peripheral artery disease (PAD) is high, but stratifying patients' risk of hospitalization at initial evaluation is challenging. We examined the association between health status at PAD presentation and risk of (1) combined all-cause hospital admissions and emergency department (ED) visits and (2) all-cause hospital admissions. Patients with claudication enrolled at US sites in the PORTRAIT registry were included. Health status was assessed using the Peripheral Artery Questionnaire (PAQ), a PAD-specific patient-reported outcome measure. Crude overall and cause-specific hospital admissions and ED visits were reported by PAQ overall summary score (PAQ-OS) ranges (0-24, 25-49, 50-74, and 75-100). Kaplan-Meier survival and unadjusted and adjusted Cox proportional hazards models examined the association between baseline PAQ scores and (1) combined all-cause hospital admissions or ED visits and (2) all-cause hospital admissions over 12 months. Of 796 patients, 349 (44%) had a hospital admission or ED visit over 12 months. Patients in the lowest (PAQ-OS = 0-24) versus the highest range (PAQ-OS = 75-100) had higher rates of 12-month (53.3% vs 22.4%) hospital admission and ED visits. In the adjusted model, each 10-point decrease in PAQ-OS was associated with a higher risk of all-cause hospital admission and ED visits (HR = 1.1, 95% CI 1.1-1.2, p < 0.0010) and all-cause hospital admission (HR = 1.1, 95% CI 1.1-1.2, p < 0.0010) at 12 months. PAD-specific health status is associated with an increased risk of healthcare utilization. Baseline health status may help stratify risk in patients with PAD, although replication and further validation of results are necessary.

Minnesota has shown relatively high growth of mortality from diabetes mellitus (DM) and dementia in recent years, especially in rural areas. Analysis of medical care utilization patterns may reveal the reasons for this trend. The goal of the present study was to characterize the Minnesota dementia and diabetes care landscape by rurality and geographic region. Specifically, we compared the Metro region to five other rural-urban regions. Disease-specific 2017 hospital admission and emergency department (ED) visit data was obtained from the State Center for Health Statistics and the Healthcare Cost and Utilization Project. We used the logistic regression analysis adjusted by multiple covariates to evaluate rural-urban differences in hospital admissions and ED visits. Age-adjusted rates of ED visits for both DM and dementia were significantly higher in rural zip code areas, especially in northeast regions. Rural areas had elevated odds for dementia hospital admissions (OR=1.05, p<0.0001) and ED visits (OR=1.24, p<0.0001), but decreased odds for DM hospital admission (OR=0.96, p<0.0001) and ED visits (OR=0.96, p<0.0001). This was particularly true in the northeast region (relative to Metro regions) where ED visits were less likely due to DM (OR=0.89, p<0.0001) but more likely related to dementia (ORs=1.42, p<0.0001). Geographic differences for ED visits due to DM were greater than those for dementia, with higher rates for rural as compared to urban regions (northeast MN compared to a large metropolitan region). This geographical mismatch between mortality rates and ED visit rates may illustrate the relative lack of access to health services in rural MN.

The Impact of Heat Waves on Emergency Department Visits in Roanoke, Virginia

Transitions of care can contribute to medication errors and other adverse drug events. The aim of this study was to evaluate the impact of pharmacist-led discharge counseling on hospital readmission and emergency department visits through a systematic review and meta-analysis. Lectronic searches were performed in PubMed, Scopus, and DOAJ (Directory of Open Access Journals), along with a manual search (July 2017). PROSPERO registration no. CRD42017068444. Two independent reviewers performed all the steps of the systematic review process (screening of titles and abstracts, full-text appraisal, data extraction, and quality assessment), with contributions from a third researcher. We included randomized controlled trials (RCTs) reporting data on pharmacist-led discharge counseling. Primary extracted outcomes were emergency department visits and hospital readmission rates. Meta-analyses of intervention versus usual care for hospital readmission and emergency department visit rates were performed using the inverse variance method. Results are reported as risk ratios (RRs) with 95% confidence intervals (CIs). Prediction intervals (PIs) were also calculated. Sensitivity and subgroup analyses were performed. A total of 21 RCTs were included in the qualitative synthesis and 18 in the meta-analyses (n = 7,244 patients). The original meta-analysis revealed a significant difference in the impact between pharmacist-led discharge counseling and usual care on overall hospital readmission (RR = 0.864 [95% CI 0.763-0.997], P = .020) and emergency department (RR = 0.697 [95% CI 0.535-0.907], P = .007) visits. However, the small number of included studies, the high heterogeneity among trials (I2 between 40% and 60%), and the wide PIs (hospital readmission: PI 0.542-1.186; emergency department visits: PI 0.027-1.367) prevented drawing further conclusions. Insufficient evidence exists regarding the effect of pharmacist-led discharge counseling on hospital readmission and emergency department visits. Further well-designed clinical trials with defined core outcome sets are needed.

Background and Aims At least 30% of acute kidney injury (AKI) survivors lack appropriate follow up after hospital discharge. AKI survivors have highly dynamic posthospital course which warrants close monitoring to prevent adverse outcomes. Digital health solutions like remote patient monitoring (RPM) could be used to improve quality and efficiency of AKI survivor care. The purpose for this study was to assess the feasibility and effectiveness of the Mayo Clinic AKI RPM program, launched in October 2021. Method The Mayo Clinic AKI RPM program enrolled individuals who experienced AKI during a hospitalization and underwent nephrology consultation (Figure 1). Feasibility was assessed as the proportion of individuals approached for AKI RPM enrollment during the first year of the program who submitted at least one set of vital signs after discharge. An effectiveness analysis compared stage 3 AKI survivors enrolled in AKI RPM with at least 30-days of follow-up to matched historical controls (3:1) sampled from before RPM was available (2018-2021). The primary endpoint was hospital readmission or emergency department (ED) visit within 30-days, assessed with the Chi-square test. Secondarily we explored time to first readmission or ED visit with a Kaplan-Meier survival curve with a non-parametric comparison between groups, as well as readmission length of stay with the Wilcoxon Rank Sum test due to right skewed data distribution. Results Of the 50 individuals approached for AKI RPM participation, 45 (90%) submitted at least one set of vitals. Among AKI RPM patients, 34 patients with stage 3 AKI were matched to 102 controls based on baseline characteristics and demographics. Dialysis during hospitalization (liberated by discharge) was used in 36 (27%) of patients. Sixty (44%) individuals required ICU level of care. Median (IQR) discharge estimated glomerular filtration rate was 15 (11, 27) mL/min/1.73m2. Through matching, groups were well balanced with respect to pertinent baseline demographics. Hospital readmission or ED visit occurred in 17 (50%) of AKI RPM patients within 30-days compared to 39 (38%) of controls within 30-days (P = .23). The endpoint appeared driven by ED visits within 30-days, not readmissions [At least one ED visit: 13 (38%) vs 21 (21%), respectively (P = .04); At least one hospital readmission: 7 (21%) vs 26 (26%), respectively (P = .56)]. Time to first readmission or ED visit within 30-days was similar between groups (P = .35; Figure 2). Among the 33 patients who were readmitted to the hospital within 30-days, readmission length of stay was similar in the AKI RPM group compared to controls [Median (IQR) 76 (10.6, 121) hours vs 108 (70, 165) hours); P = 0.33]. Conclusion In conclusion, AKI RPM was a feasible program when used to bridge the care continuum (hospital to home) in non-dialysis dependent AKI survivors. Incidence of at least one hospital readmission or ED visit within 30-days was statistically similar between AKI RPM patients and controls. More AKI RPM patients experienced ED encounters in the 30-days after discharge, but frequency of hospital readmission was similar. Digital health solutions such as RPM offer a unique opportunity to address the important gap in AKI care after discharging from the hospital. Additional research is needed to explore the impact of AKI RPM on patient outcomes.

States that have legalized cannabis for medicinal or retail use have noted increases in emergency department (ED) visits associated with cannabis-associated harms. However, most studies are retrospective and identify cannabis-related visits using diagnosis codes or THC-positive urine drug immunoassays. These identification methods are limited. ICD codes are infrequently used in adult ED cases of exposure to drugs of abuse and clinicians may not explicitly document diagnosis of drug use, even when highly suspected or confirmed by patients.

To estimate associations between clinical and socioeconomic variables and hospital days and emergency department (ED) visits for children with medical complexity (CMCs) for 5 years after index admission. Retrospective, longitudinal, population-based cohort study of CMCs in Alberta (n = 12 621) diagnosed between 2010 and 2013 using administrative data linked to socioeconomic data. The primary outcomes were annual cumulative numbers of hospital days and ED visits for 5 years after index admission. Data were analyzed using mixed-effect hurdle regression. Among CMCs utilizing resources, those with more chronic medications had more hospital days (relative difference [RD] 3.331 for ≥5 vs 0 medications in year 1, SE 0.347, P value < .001) and ED visits (RD 1.836 for 0 vs ≥5 medications in year 1, SE 0.133, P value < .001). Among these CMCs, initial length of stay had significant, positive associations with hospital days (RD 1.960-5.097, SE 0.161-0.610, P value < .001 outside of the gastrointestinal and hematology and immunodeficiency groups). Those residing in rural or remote areas had more ED visits than those in urban or metropolitan locations (RD 1.727 for rural versus urban, SE 0.075, P < .001). Material and social deprivation had significant, positive associations with number of ED visits. Clinical factors are more strongly associated with hospitalizations and socioeconomic factors with ED visits. Policy administrators and researchers aiming to optimize resource use and improve outcomes for CMCs should consider interventions that include both clinical care and socioeconomic support.

Impact of the care coordination program “Partners in Dementia Care” on veterans' hospital admissions and emergency department visits

Background: Saudi Arabian hospital readmissions and emergency department (ED) visits following bariatric surgery and discharge have never been investigated. This study aimed to evaluate the rates and reasons of hospital readmissions and ED visits related to surgical weight loss interventions at the King Abdulaziz Medical City - Riyadh. Methods: We conducted a retrospective cohort study on 301 patients who underwent bariatric surgery between January 2011 and July 2016. We reviewed patient medical records progressively to assess hospital readmission, ED visits, and complications. Results: Of the 301 patients analyzed, 67.1% were female and 93% had class II obesity. The readmission rate, ED visit rate after discharge and the rate of either of the two was 8%, 14%,and 18.3%, respectively. The most common causes of readmission were abdominal pain (37.5%), nausea/vomiting (29.2%), and site leak (25%), while the most common causes of ED visits were abdominal pain (59.5%) and nausea/vomiting (16.9%). Readmission rates tended to be higher in older patients (age of patients readmitted 42 ± 12.1 years vs. age of patients not readmitted 34.3 ± 11.8 years; p = 0.002). The rate of readmission tends to increase in patients with overweight or class I obesity (odds ratio (OR) = 20.15), diabetes (OR = 14.82), and obstructive sleep apnea (OR = 14.29). Dyslipidemia was positively associated with ED visits (p = 0.027, OR = 2.87). The rate of readmission or ED visits increased with age, while there were decreases in readmission and ED visits for those who had received gastric sleeve surgery. Conclusions: The study reported high rates of readmission and ED visits, thus the effectiveness of different types of weight loss surgeries should be further evaluated, particularly in individuals with complicated medical issues such as diabetes, dyslipidemia, and obstructive sleep apnea.

197 Background: St. Michael’s Hospital (SMH) is an academic, inner-city hospital in Toronto, Canada. In the hematology/oncology (hem/onc) program, a small number of patients appeared to contribute disproportionately to hospital admissions and emergency department (ED) visits. We hypothesized that high needs hem/onc patients could be recognized early in their care and that ED visit and admission rates among these patients could be decreased through targeted interventions. Methods: Members of the hem/onc team were interviewed regarding characteristics, which they felt predicted higher needs and greater liklihood for hospital admission/ED visit. A list of high risk features was generated. ED visit and admission rates for a prospectively identified high needs cohort were compared to rates for the entire hem/onc clinic. An intervention targeting high needs hem/onc patients is on-going. Pre and post-intervention ED visit and admission rates will be compared. Results: Interviews with 3 nurses, 1 social worker, 1 discharge planner, and 4 physicians identified 10 factors that the hem/onc team believed were predictive of higher needs and subsequent higher ED visit and admission rates. Between December 1, 2012, and February 28, 2013, 42 high needs hem/onc out-patients were prospectively identified. The ED visit and admission rates for this cohort were retrospectively compared to those of the entire hem/onc clinic and found to be dramatically higher (Table). Begininng in June 2013, hem/onc patients identified as “high needs” were offered enrollment in a NP-based program offering telephone assessments following ED visits, hospital admissions or discharges. Assessment of the impact of this intervention is ongoing. Conclusions: It is possible to prospectively identify hem/onc patients who are at risk of higher than usual ED visit and admission rates. Identifying this population may provide an opportunity to decrease their ED visit and admission rates. An evaluation of an intervention targeting high needs hem/onc patients is ongoing. Preliminary data will be presented. [Table: see text]

Hospital-Based, Acute Care Use Among Patients Within 30 Days of Discharge After Coronary Artery Bypass Surgery

IntroductionThis study analyzes changes in hospital emergency department (ED) visit rates before and after the 2014 Affordable Care Act (ACA) insurance expansions in Illinois. We compare the association between population insurance status change and ED visit rate change between a 24-month (2012–2013) pre-ACA period and a 24-month post-ACA (2014–2015) period across 88 socioeconomically diverse areas of Illinois.MethodsWe used annual American Community Survey estimates for 2012–2015 to obtain insurance status changes for uninsured, private, Medicaid, and Medicare (disability) populations of 88 Illinois Public Use Micro Areas (PUMAs), areas with a mean of about 90,000 age 18–64 residents. Over 12 million ED visits to 201 non-federal Illinois hospitals were used to calculate visit rates by residents of each PUMA, using population-based mapping weights to allocate visits from zip codes to PUMAs. We then estimated n=88 correlations between population insurance-status changes and changes in ED visit rates per 1,000 residents comparing the two years before and after ACA implementation.ResultsThe baseline PUMA uninsurance rate ranged from 6.7% to 41.1% and there was 4.6-fold variation in baseline PUMA ED visit rates. The top quartile of PUMAs had >21,000 reductions in uninsured residents; 16 PUMAs had at least a 15,000 person increase in Medicaid enrollment. Compared to 2012–2013, 2014–2015 average monthly ED visits by the uninsured dropped 42%, but increased 42% for Medicaid and 10% for the privately insured. Areas with the largest increases in Medicaid enrollment experienced the largest growth in ED use; change in Medicaid enrollment was the only significant correlate of area change in total ED visits and explained a third of variation across the 88 PUMAs.ConclusionACA implementation in Illinois accelerated existing trends towards greater use of hospital ED care. It remains to be seen whether providing better access to primary and preventive care to the formerly uninsured will reduce ED use over time, or whether ACA insurance expansion is a part of continued, long-term growth. Monitoring ED use at the local level is critical to the success of new home- and community-based care coordination initiatives.

The aim of this study was to explore the efficacy of current bariatric perioperative measures at reducing emergency department (ED) visits following bariatric surgery in the state of Michigan. Many ED visits following bariatric surgery do not result in readmission and may be preventable. Little research exists evaluating the efficacy of perioperative measures aimed at reducing ED visits in this population. Therefore, understanding the driving factors behind these preventable ED visits may be a fruitful approach to prevention. Furthermore, evaluating the efficacy of current perioperative measures may shed light on how to achieve meaningful reductions in ED visits. We studied 48,035 eligible bariatric surgery patients across 37 Michigan Bariatric Surgical Collaborative (MBSC) sites between January 2012 and October 2015. Hospitals were ranked according to their risk- and reliability-adjusted ED visit rates. For hospitals in each ED visit rate tercile, several patient, surgery, and hospital summary characteristics were compared. We then studied whether a hospital's compliance with specific perioperative measures was significantly associated with reduced ED visit rates. Only 3 of the 30 surgery, hospital, and patient summary characteristics studied were significant predictors of a hospital's ED visit rate: rate of sleeve gastrectomies, rate of readmissions, and rate of venous thromboembolism complications (P = 0.04, P = 0.0065, and P = 0.0047, respectively). Also, a hospital's compliance with the perioperative measures evaluated was not a significant predictor of ED visit rates (P = 0.12). Current practices aimed at reducing ED visits appear to be ineffective. Due to heterogeneity in patient populations and local infrastructure, a more tailored approach to ED visit reduction may be more successful.

BackgroundCurrent policies recommend integrating home care and palliative care to enable patients to remain at home and avoid unnecessary hospital admission and emergency department (ED) visits. The Italian health care system had implemented integrated palliative home care (IHPC) services to guarantee a comprehensive, coordinated approach across different actors and to reduce potentially avoidable ED visits. This study aimed to analyze the trajectories of ED visit rates among patients receiving IHPC in the Italian healthcare system, as well as the association between socio-demographic, health supply, and clinical factors.MethodsA pooled, cross-sectional, time series analysis was performed in a large Italian region in the period 2013–2017. Data were taken from two databases of the official Italian National Information System: Home Care Services and ED use. A clinical record is opened at the time a patient is enrolled in IHPC and closed after the last service is provided. Every such clinical record was considered as an IHPC event, and only ED visits that occurred during IHPC events were considered.ResultsThe 20,611 patients enrolled in IHPC during the study period contributed 23,085 IHPC events; ≥1 ED visit occurred during 6046 of these events. Neoplasms accounted for 89% of IHPC events and for 91% of ED visits. Although there were different variations in ED visit rates during the study period, a slight decline was observed for all diseases, and this decline accelerated over time (b = − 0.18, p = 0.796, 95% confidence interval [CI] = − 1.59;1.22, b-squared = − 1.25, p < 0.001, 95% CI = -1.63;-0.86). There were no significant predictors among the socio-demographic factors (sex, age, presence of a non-family caregiver, cohabitant family members, distance from ED), health supply factors (proponent of IHPC) and clinical factors (prevalent disorder at IHPC entry, clinical symptoms).ConclusionOur results show that use of ED continues after enrollment in IHPC, but the trend of this use declines over time. As no significant predictive factors were identified, no specific interventions can be recommended on which the avoidable ED visits depend.
