Effect of an ultrasound-first clinical decision tool in emergency department patients with suspected nephrolithiasis: A randomized trial

IntroductionPreviously, we found that the use of ultrasonography for patients with suspected nephrolithiasis resulted in similar outcomes and less radiation exposure vs. CT scan. In this study, we evaluated the implementation of an ultrasound-first clinical decision support (CDS) tool in patients with suspected nephrolithiasis. MethodsThis randomized trial was conducted at an academic emergency department (ED). We implemented the ultrasound-first CDS tool, deployed when an ED provider placed a CT order for suspected nephrolithiasis. Providers were randomized to receiving the CDS tool vs. usual care. The primary outcome was receipt of CT during the index ED visit. Secondary outcomes included radiation dose and ED revisit. Results64 ED Providers and 254 patients with suspected nephrolithiasis were enrolled from January 2019 through Dec 2020. The US-First CDS tool was deployed for 128 patients and was not deployed for 126 patients. 86.7% of patients in the CDS arm received a CT vs. 94.4% in the usual care arm, resulting in an absolute risk difference of −7.7% (−14.8 to −0.6%). Mean radiation dose in the CDS arm was 6.8 mSv (95% CI 5.7–7.9 mSv) vs. 6.1 mSv (95% CI 5.1–7.1 mSv) in the usual care arm. The CDS arm did not result in increased ED revisits, CT scans, or hospitalizations at 7 or 30 days. Conclusions and relevanceImplementation of the US-first CDS tool resulted in lower CT use for ED patients with suspected nephrolithiasis. The use of this decision support may improve the evaluation of a common problem in the ED.Trial Registration:ClinicalTrials.gov#NCT03461536

Syncope and the Risk of Subsequent Motor Vehicle Crash

Medical driving restrictions are burdensome, yet syncope recurrence while driving can cause a motor vehicle crash (MVC). Few empirical data inform current driving restrictions after syncope. To examine MVC risk among patients visiting the emergency department (ED) after first-episode syncope. A population-based, retrospective observational cohort study of MVC risk after first-episode syncope was performed in British Columbia, Canada. Patients visiting any of 6 urban EDs for syncope and collapse were age- and sex-matched to 4 control patients visiting the same ED in the same month for a condition other than syncope. Patients' ED medical records were linked to administrative health records, driving history, and detailed crash reports. Crash-free survival among individuals with syncope was then compared with that among matched control patients. Data analyses were performed from May 2020 to March 2022. Initial ED visit for syncope. Involvement as a driver in an MVC in the year following the index ED visit. Crashes were identified using insurance claim data and police crash reports. The study cohort included 43 589 patients (9223 patients with syncope and 34 366 controls; median [IQR] age, 54 [35-72] years; 22 360 [51.3%] women; 5033 [11.5%] rural residents). At baseline, crude MVC incidence rates among both the syncope and control groups were higher than among the general population (12.2, 13.2, and 8.2 crashes per 100 driver-years, respectively). In the year following index ED visit, 846 first crashes occurred in the syncope group and 3457 first crashes occurred in the control group, indicating no significant difference in subsequent MVC risk (9.2% vs 10.1%; adjusted hazard ratio [aHR], 0.93; 95% CI, 0.87-1.01; P = .07). Subsequent crash risk among patients with syncope was not significantly increased in the first 30 days after index ED visit (aHR, 1.07; 95% CI, 0.84-1.36; P = .56) or among subgroups at higher risk of adverse events after syncope (eg, age >65 years; cardiogenic syncope; Canadian Syncope Risk Score ≥1). The findings of this population-based retrospective cohort study suggest that patients visiting the ED with first-episode syncope exhibit a subsequent crash risk no different than the average ED patient. More stringent driving restrictions after syncope may not be warranted.

Post–COVID-19 Conditions Among Children 90 Days After SARS-CoV-2 Infection

Little is known about the risk factors for, and the risk of, developing post-COVID-19 conditions (PCCs) among children. To estimate the proportion of SARS-CoV-2-positive children with PCCs 90 days after a positive test result, to compare this proportion with SARS-CoV-2-negative children, and to assess factors associated with PCCs. This prospective cohort study, conducted in 36 emergency departments (EDs) in 8 countries between March 7, 2020, and January 20, 2021, included 1884 SARS-CoV-2-positive children who completed 90-day follow-up; 1686 of these children were frequency matched by hospitalization status, country, and recruitment date with 1701 SARS-CoV-2-negative controls. SARS-CoV-2 detected via nucleic acid testing. Post-COVID-19 conditions, defined as any persistent, new, or recurrent health problems reported in the 90-day follow-up survey. Of 8642 enrolled children, 2368 (27.4%) were SARS-CoV-2 positive, among whom 2365 (99.9%) had index ED visit disposition data available; among the 1884 children (79.7%) who completed follow-up, the median age was 3 years (IQR, 0-10 years) and 994 (52.8%) were boys. A total of 110 SARS-CoV-2-positive children (5.8%; 95% CI, 4.8%-7.0%) reported PCCs, including 44 of 447 children (9.8%; 95% CI, 7.4%-13.0%) hospitalized during the acute illness and 66 of 1437 children (4.6%; 95% CI, 3.6%-5.8%) not hospitalized during the acute illness (difference, 5.3%; 95% CI, 2.5%-8.5%). Among SARS-CoV-2-positive children, the most common symptom was fatigue or weakness (21 [1.1%]). Characteristics associated with reporting at least 1 PCC at 90 days included being hospitalized 48 hours or more compared with no hospitalization (adjusted odds ratio [aOR], 2.67 [95% CI, 1.63-4.38]); having 4 or more symptoms reported at the index ED visit compared with 1 to 3 symptoms (4-6 symptoms: aOR, 2.35 [95% CI, 1.28-4.31]; ≥7 symptoms: aOR, 4.59 [95% CI, 2.50-8.44]); and being 14 years of age or older compared with younger than 1 year (aOR, 2.67 [95% CI, 1.43-4.99]). SARS-CoV-2-positive children were more likely to report PCCs at 90 days compared with those who tested negative, both among those who were not hospitalized (55 of 1295 [4.2%; 95% CI, 3.2%-5.5%] vs 35 of 1321 [2.7%; 95% CI, 1.9%-3.7%]; difference, 1.6% [95% CI, 0.2%-3.0%]) and those who were hospitalized (40 of 391 [10.2%; 95% CI, 7.4%-13.7%] vs 19 of 380 [5.0%; 95% CI, 3.0%-7.7%]; difference, 5.2% [95% CI, 1.5%-9.1%]). In addition, SARS-CoV-2 positivity was associated with reporting PCCs 90 days after the index ED visit (aOR, 1.63 [95% CI, 1.14-2.35]), specifically systemic health problems (eg, fatigue, weakness, fever; aOR, 2.44 [95% CI, 1.19-5.00]). In this cohort study, SARS-CoV-2 infection was associated with reporting PCCs at 90 days in children. Guidance and follow-up are particularly necessary for hospitalized children who have numerous acute symptoms and are older.

Hospital presentations with diabetic ketoacidosis: A retrospective review

BackgroundDiabetic ketoacidosis (DKA) is a significant source of preventable episodes of care and cost. This study aimed to describe the demographic and clinical characteristics of people with type 1 diabetes (T1D) presenting to the Emergency Department (ED) with DKA in an area of socio-economic deprivation in metropolitan Queensland, Australia, and to describe factors associated with hospital admission and re-presentation in this population. MethodsThis was a retrospective descriptive analysis of routine healthcare record data for January 2015-December 2019. People with T1D were identified through hospital discharge codes. ResultsMore than half (n = 165) the estimated local T1D population (n = 317) experienced an index ED presentation for DKA; mean±SD age at ED presentation was 31.1 + /− 19.3 years, 126 (76.4%) were aged ≥ 16 years and 20 (12.1%) were newly diagnosed. Index DKA presentation was significantly associated with female sex (p = 0.04) but no other demographic or geographic variables. More than half the presentations (n = 92, 55.8%) occurred outside regular business hours. Twenty-three representations occurred within 90 days, associated with older age (p = 0.045) and lower residential socio-economic score (p = 0.02). ConclusionFindings highlight the frequent problem of DKA and the importance of socio-economic influences. This flags the need and opportunity to improve support to people with T1D to promote diabetes self-care.

The effect of direct admission to acute geriatric units compared to admission after an emergency department visit on length of stay, postacute care transfers and ED return visits

BackgroundCompared with conventional hospitalization, admission to an acute geriatric care unit (AGU) is associated with better outcomes in elderly patients. In 2012, 50% of the hospitalizations of elderly patients were preceded by an emergency department (ED) visit. Hospital occupancy, access blocks and overcrowding experienced by patients during ED visits are associated with increased morbidity.ObjectiveOur aim was to evaluate the effect of direct admission (DA) to an AGU on both the hospital length of stay and morbidity of elderly patients.DesignThis study was a retrospective cohort study conducted using electronic medical records and administrative claims data from the Greater Paris University Hospitals (APHP) health data warehouse involving 19 different AGUs.ParticipantsWe included all patients ≥ 75 years old who were admitted to an AGU for more than 24 h between January 1, 2013, and December 31, 2018.InterventionDirect admission to the AGU compared to admission after an ED visit.Main measuresThe main outcome was hospital length of stay. Two outcomes were used to analyse morbidity: postacute care and rehabilitation ward transfer at the end of the index hospitalization and ED return visit within 30 days after the index hospitalization (for those who survived to hospitalization). We used an inverse probability of treatment weighting (IPTW) approach to balance the differences in patient baseline variables between the two groups. Univariate linear and logistic regression models were built to estimate the effect of DA on hospital length of stay and the likelihood of postacute care transfer and ED return visit.Key resultsAmong the 6583 patients included in the study, DA was associated with a lower hospital length of stay (estimate = -1.28; 95% CI = -1.76–0.80), and a lower likelihood of postacute care transfer (OR = 0.87; 95% CI = 0.77–0.97). It was not significantly associated with a lower risk of ED return visits (OR = 0.81; 95% CI = 0.60–1.08) in the following month.ConclusionDA should be prioritized, and reorganization of the geriatric pathway around DA should be encouraged due to the frailty of elderly individuals.

Stage-of-change Assessment Predicts Short-term Treatment Engagement for Opioid Use Disorder Patients Initiated on Buprenorphine.

IntroductionThe emergency department (ED) is an effective setting for initiating medication for opioid use disorder (MOUD); however, predicting who will remain in treatment remains a central challenge. We hypothesize that baseline stage-of-change (SOC) assessment is associated with short-term treatment retention outcomes.MethodsThis is a longitudinal cohort study of all patients enrolled in an ED MOUD program over 12 months. Eligible and willing patients were treated with buprenorphine at baseline and had addiction medicine specialist follow-up arranged. Treatment retention at 30 and 90 days was determined by review of the Prescription Drug Monitoring Program. We used uni- and multivariate logistic regression to evaluate associations between patient variables and treatment retention at 30 and 90 days.ResultsFrom June 2018–May 2019, 279 patients were enrolled in the ED MOUD program. Of those patients 151 (54.1%) and 120 (43.0%) remained engaged in MOUD treatment at 30 and 90 days, respectively. The odds of treatment adherence at 30 days were significantly higher for those with advanced SOC (preparation/action/maintenance) compared to those presenting with limited SOC (pre-contemplation/contemplation) (60.0% vs 40.8%; odds ratio 2.18; 95% confidence interval 1.15 to 4.1; P <0.05). At 30 days, multivariate logistic regression determined that advanced SOC, age >40, having medical insurance, and being employed were significant predictors of continued treatment adherence. At 90 days, advanced SOC, non-White race, age > 40, and having insurance were all significantly associated with higher likelihood of treatment engagement.ConclusionGreater stage-of-change was significantly associated with MOUD treatment retention at 30 and 90 days post index ED visit.

Pediatric Return Visits to the Emergency Department: The Time to Return Curve.

Although 72-hour return visits are a frequently reported metric for pediatric patients discharged from the emergency department (ED), the basis for this metric is not established. Our objective was to statistically derive a cutoff time point for the characterization of pediatric return visits. We performed a retrospective cohort study using data of patients discharged from any of 44 pediatric EDs. We selected the first encounter per patient from January 1 to December 31, 2019, as the index encounter and included the first return visit within 30 days. We constructed a cumulative hazard curve to characterize the timing of return visits and constructed a multivariable adaptive regression spline model to identify a hinge point in return visit presentations. We identified the association between admission for early return visits and admission for late return visits using generalized linear mixed modeling. Of 1,986,778 index ED discharges, 193,605 (9.7%) ED return visits were included. A double-exponential decay model demonstrated superior fit compared with a single exponential model ( P < 0.0001). Multivariable adaptive regression spline modeling identified a hinge at 7 days. When comparing proportions of return visits leading to hospitalization between early (23.8%) and late (15.1%) return visits, early visits (≤7 days) had higher adjusted odds of hospital admission (adjusted odds ratio, 1.73; 95% confidence interval, 1.69-1.77) relative to late return visits (>7 days). Findings were similar in sensitivity analyses within age subgroups, Census region, and in which the diagnosis (using the Diagnosis and Grouping System) was the same between the index and return visit. Among return visits that occurred within 7 days of the index visit, 46.3% had the same diagnosis grouping in both visits. An empirically derived 7-day cutoff may be more appropriate for characterization of pediatric return visits to the ED. Encounters after this period had lower adjusted odds of admission.

Using network analysis to model the effects of the SARS Cov2 pandemic on acute patient care within a healthcare system

Consolidation of healthcare in the US has resulted in integrated organizations, encompassing large geographic areas, with varying services and complex patient flows. Profound changes in patient volumes and behavior have occurred during the SARS Cov2 pandemic, but understanding these across organizations is challenging. Network analysis provides a novel approach to address this. We retrospectively evaluated hospital-based encounters with an index emergency department visit in a healthcare system comprising 18 hospitals, using patient transfer as a marker of unmet clinical need. We developed quantitative models of transfers using network analysis incorporating the level of care provided (ward, progressive care, intensive care) during pre-pandemic (May 25, 2018 to March 16, 2020) and mid-pandemic (March 17, 2020 to March 8, 2021) time periods. 829,455 encounters were evaluated. The system functioned as a non-small-world, non-scale-free, dissociative network. Our models reflected transfer destination diversification and variations in volume between the two time points – results of intentional efforts during the pandemic. Known hub-spoke architecture correlated with quantitative analysis. Applying network analysis in an integrated US healthcare organization demonstrates changing patterns of care and the emergence of bottlenecks in response to the SARS Cov2 pandemic, consistent with clinical experience, providing a degree of face validity. The modelling of multiple influences can identify susceptibility to stress and opportunities to strengthen the system where patient movement is common and voluminous. The technique provides a mechanism to analyze the effects of intentional and contextual changes on system behavior.

Emergency and post-emergency care of older adults with Alzheimer's disease/Alzheimer's disease related dementias.

The emergency department (ED) is a critical juncture in the care of persons living with dementia (PLwD), as they have a high rate of hospital admission, ED revisits, and subsequent inpatient stays. We examine ED disposition of PLwD compared with older adults with non-dementia chronic disease as well as healthcare utilization and survival. Medicare claims data were used to identify community-dwelling older adults 66+ years old from 34 hospitals with either Alzheimer's disease/Alzheimer's disease related dementias (AD/ADRD) or a non-AD/ADRD chronic condition between January 1, 2014, and December 31, 2018. We compared ED disposition at the index visit, as well as healthcare utilization and mortality in the 12 months following an index ED visit, and adjusted for age, gender, and risk of mortality. There were 29,626 patients in the AD/ADRD sample, and 317,046 in the comparison sample. The AD/ADRD sample was older (82.4 years old [SD: 8.2] vs. 76.0 years old [SD: 7.7]) and had more female patients (59.9% vs. 54.7%). The AD/ADRD sample was more likely to experience ED disposition to acute care (OR 1.039, p< 0.001, 95% CI 1.029-1.050), to have an ED revisit (OR 1.077, p< 0.001, 95% CI 1.066-1.087), and an inpatient stay in the subsequent 12 months (OR 1.085, p< 0.001, 95% CI 1.075-1.095). ED disposition to hospice was low in both samples (0.2%). AD/ADRD patients had a higher risk of mortality (OR 1.099, p< 0.001, 95% CI 1.091-1.107) and high short-term mortality (31.9% within 12 months) than those without AD/ADRD (15.3% within 12 months). PLwD who visit the ED have high short-term mortality. Despite this, disposition to acute care, ED revisits, and inpatient stays, rather than hospice, remain the predominant mode of care delivery. Transition directly from the ED to hospice for PLwD is rare.

Follow-up after ED visits for opioid use disorder: Do they reduce future overdoses?

IntroductionFollow-up visits within 7 days of an emergency department (ED) visit related to opioid use disorder (OUD) is a key measure of treatment quality, but we know little about its protective effect on future opioid-related overdoses. The objective this paper is to examine the rate of 7-day follow-up after an OUD-related ED visit and the association with future overdoses. MethodsRetrospective analysis of Medicaid enrollees in 11 states that had an OUD-related ED visit from 2016 through 2018. Each state used Cox proportional hazard models to estimate the association between having a follow-up visit within 7 days of an OUD-related ED visit, and an overdose within 6 months of the ED visit. State analyses were pooled to generate global estimates using random effects meta-analysis. ResultsAmong 114,945 Medicaid enrollees with an OUD-related ED visit, 15.7% had a follow-up visit within 7 days. State-specific rates varied from 7.2% to 22.4% across the 11 states. Compared to those with no follow-up visit, enrollees with a follow-up visit were more likely to be female, non-Hispanic White, less likely to have had an overdose or other substance use disorder at the time of the ED visit, and much more likely to have been receiving MOUD treatment prior to the ED visit. Global estimates based on multivariate analysis showed that having a 7-day follow-up visit was associated with a lower likelihood of overdose within 6 months of the index ED visit (HR = 0.91, CI = 0.84, 0.99). However, states had considerable heterogeneity in this association, with only two states having statistically significant results. ConclusionsAmong Medicaid enrollees with OUD, having a follow-up visit 7 days after an ED visit is protective against fatal or nonfatal overdose within 6 months, although the association varies considerably across states. Although the association with future overdoses was relatively modest, both practitioners and policymakers should seek to increase the number of Medicaid enrollees with OUD who receive follow-up care within 7 days after an ED visit.

“Emergency Room Evaluation and Recommendations” and Incident Hospital Admissions in Older People with Major Neurocognitive Disorders Visiting Emergency Department: Results of an Experimental Study

Introduction: Older people with major neurocognitive disorders (MNCDs) visiting the emergency department (ED) are at high risk of hospital admissions. The “Emergency Room Evaluation and Recommendations” (ER²) tool decreases the length of stay (LOS) in the hospital when older people visiting ED are hospitalized after an index ED visit, regardless of their cognitive status. Its effect on hospital admissions has not yet been examined in older people with MNCD visiting ED. This study aimed to examine whether ER² recommendations were associated with incident hospital admissions and LOS in ED in older people with MNCD visiting ED. Methods: A total of 356 older people with MNCD visiting ED of the Jewish General Hospital (Montreal, Quebec, Canada) were recruited in this non-randomized, pre-post-intervention, single arm, prospective and longitudinal open label trial. ED staff and patients were blinded of the ER² score, and patients received usual ED care during the observation period, whereas ED staff were informed about the ER² score, and patients had ER² tailor-made recommendations in addition to usual care during the intervention period. Hospital admissions and the LOS in ED were the outcomes. Results: There were less incident hospital admissions (odds ratio ≤ 0.61 with p ≤ 0.022) and longer LOS in ED (coefficient beta ≥4.28 with p ≤ 0.008) during the intervention period compared to the observation period. Discussion/Conclusion: ER² recommendations have mixed effects in people with MNCD visiting ED. They were associated with reduced incident hospital admissions and increased LOS in ED, suggesting that they may have benefits in addition to usual ED care.

Improving care coordination and reducing ED utilization through patient navigation.

Our study examines the impact of an emergency department (ED) patient navigation program for patients in a Medicaid accountable care organization across 3 hospitals in a large health system. Our program engages community health workers to (1) promote primary care engagement, (2) facilitate care coordination, and (3) identify and address patients' health-related social needs. Our study was a retrospective analysis of health care utilization and costs in the 30 days following the index ED visit, comparing individuals receiving ED navigation and matched controls. The primary outcome of interest was all-cause return ED visits, and our secondary outcomes were hospital admissions and completed primary care appointments. Patients with ED visits who received navigation were matched to comparable patients with ED visits without an ED navigator interaction. Outcomes were analyzed using fixed effects logistic regression models adjusted for patient demographics, ED visit characteristics, and preceding utilization. Our primary outcome was odds of a return ED visit within 30 days, and our secondary outcomes were odds of a hospitalization within 30 days and odds of having primary care visit within 30 days. In our sample, there were 1117 ED visits by patients meeting our inclusion criteria with an ED navigator interaction, with 3351 matched controls. ED navigation was associated with 52% greater odds of a completed follow-up primary care appointment (odds ratio [OR], 1.52; 95% CI, 1.29-1.77). In patients with no ED visits in the preceding 6 months, ED navigation was associated with 32% decreased odds of repeat ED visits in the subsequent 30 days (OR, 0.68; 95% CI, 0.52-0.90). There was no statistically significant impact on return ED visits in those with higher baseline ED utilization. Our program demonstrates that high-intensity, short-term patient navigation in the ED can help reduce ED visits in those with low baseline ED utilization and facilitate stronger connections with primary care.

Risk of intracranial hemorrhage between different direct oral anticoagulants in older patients seen in the emergency department with a head injury: A population-based cohort study

IntroductionPatients taking direct oral anticoagulants (DOACs) are increasingly managed in emergency departments (ED). It is unknown whether the risk of traumatic intracranial hemorrhage (ICH) after a head injury differs between DOACs. The objective of this study was to compare risk of ICH at the index ED visit among older adults presenting to the ED with a head injury prescribed different DOACs. MethodsRetrospective cohort study using population-based administrative databases from Ontario, Canada between 2016 and 2018 of patients age 65 years and older prescribed DOACs who were seen in the ED with a head injury. Patients were matched on the propensity score to create three pairwise-matched cohorts based on the DOAC prescribed (dabigatran vs rivaroxaban; dabigatran vs apixaban; rivaroxaban vs apixaban). For each cohort, relative risk (RR) and 95% confidence intervals (CI) of ICH diagnosed at the index ED visit were calculated. ResultsWe identified 9230 older adults presenting with a head injury prescribed a DOAC. There were 1274 (13.8%) patients with a prescription for dabigatran, 3136 (34.0%) patients with a prescription for rivaroxaban, and 4820 (52.2%) patients with a prescription for apixaban. Overall, 5.9% of patients had an ICH at the index ED visit. After matching, there were no significant differences in the risk of ICH between any matched DOAC cohorts. ConclusionIn patients aged 65 years and older with a prescription for a DOAC seen in the ED for a head injury, there were no differences in the risk of ICH between DOACs.

Follow-up after post-partum psychiatric emergency department visits: an equity-focused population-based study in Canada

Emergency department visits for a psychiatric reason in the post-partum period represent an acute need for mental health care at a crucial time, but little is known about the extent of timely outpatient follow-up after these visits or how individual and intersecting social determinants of health influence this outcome. This study aimed to examine outpatient mental health care follow-up by a physician in the 30 days after an individual attended the emergency department for a psychiatric reason in the post-partum period and understand how social determinants of health affect who receives follow-up care. In this population-based cohort study, routinely collected health data from Ontario, Canada were accessed through ICES to identify all post-partum individuals whose sex was listed as female on their health card and who had attended an emergency department in Ontario before the COVID-19 pandemic for a psychiatric reason. Individuals admitted to hospital at the time of the emergency department visit, who died during the visit, or who left without being seen were excluded from the study. Ethnicity data for individuals were not collected. The primary outcome was the proportion of individuals with any outpatient physician (psychiatrist or family physician) visit for a mental health reason within 30 days of the index emergency department visit. Family physician mental health visits were identified using a validated algorithm for Ontario Health Insurance Plan-billed visits and mental health diagnostic codes for community health centre visits. We examined the associations between social determinants of health (age, neighbourhood income, community size, immigration, neighbourhood ethnic diversity) and who received an outpatient mental health visit. We used modified Poisson regression adjusting for the other social determinants of health, clinical, and health services characteristics to examine independent associations with follow-up, and conditional inference trees to explore how social determinants of health intersect with each other and with clinical and health services characteristics in relation to follow-up. We analysed data collected between April 1, 2008, and March 10, 2020, after exclusions we identified 12 158 people who had attended the emergency department for a psychiatric reason in the post-partum period (mean age 26·9 years [SD 6·2]; range 13-47); 9848 individuals lived in an urban area, among these 1518 (15·5%) were immigrants and 2587 (26·3%) lived in areas with high ethnic diversity. 5442 (44·8%) of 12 158 individuals received 30-day follow-up. In modified Poisson regression models, younger age, lower neighbourhood income, smaller community size, and being an immigrant were associated with a lower likelihood of follow-up. In the CTREE, similar variables were important, with several intersections between social determinants of health and between social determinants of health and other variables. Fewer than half of emergency department visits for a psychiatric reason in the post-partum period were followed by timely outpatient care, with social-determinants-of-health-based disparities in access to care. Improvements in equitable access to post-emergency department mental health care are urgently needed in this high-risk post-partum population.

5-year follow-up at an accredited community bariatric practice: what is an acceptable follow-up rate?

Adequate long-term follow-up after metabolic and bariatric surgery (MBS) remains a challenge. To evaluate if type of insurance correlated with differences in the 5-year follow-up and outcomes of a cohort of bariatric surgery patients in a community-based accredited center. Accredited private practice bariatric center in the United States. We studied bariatric surgery patients that underwent MBS in 2015 by a single surgeon in an accredited, community practice. Electronic medical records were utilized to evaluate 5-year follow-up and outcomes data. This included demographics, type of insurance, number of follow-up visits, height, weight, body mass index (BMI), postbariatric procedures, and postbariatric emergency department (ED) utilization. There were 89 patients. The follow-up rate decreased over time, with 1% of patients at 5 years. There was a slightly higher follow-up rate in patients with commercial versus public insurance. The average BMI of patients that followed up decreased by 13.6 kg/m2 over the first postoperative year. The average number of ED visits was 1.46 (standard deviation: 2.38) overall; however, of the 89 total patients, 35 patients (39.3%) had no documented ED visits, with the remaining 61 patients (63.5%) ranging from 1-15 visits (median = 1). Overall follow-up rates were low with 4-year follow-up being 14% and 5-year follow-up being <1%. Publicly insured patients had a higher rate of follow-up. Despite low follow-up rates with the actual bariatric surgery practice, 63.5% of patients had an ED visit during the follow-up period.

Emergency Department Utilization Patterns in Patients with Opioid-Related Emergency Department Visits

Background: Opioid-related Emergency Department (ED) visits have surged over the past decade. There is limited data on ED utilization patterns of patients with opioid use disorder (OUD). An improved understanding of utilization may underscore missed opportunities for screening, intervention and referral. Methods: This was a retrospective 2:1 matched case-control study conducted at a single urban ED. Cases were patients with an opioid-related index ED visit from June 1, 2017 to May 31, 2018. Controls were patients with a non-opioid related index ED visit from June 1, 2018 to May 31, 2019. The primary outcome was the association between the number of ED visits in the 24-month period surrounding the index visit (12 months prior and 12 months following) and having an opioid-related index ED visit. Results: There were a total of 224 cases. One or more visits preceding (OR: 1.63, 95% CI: 1.17, 2.26) and following the index visit (OR: 2.69, 95% CI: 1.91, 3.78) was significantly associated with case status. Following adjustment, a higher number of visits preceding (aOR: 1.24, 95% CI: 1.08, 1.43) and following the index visit (aOR: 1.39, 95% CI: 1.23, 1.57) remained significantly associated with case status. Conclusion: Patients with an opioid-related index ED visit had significantly higher rates of ED utilization 12 months before and after the index visit when compared to a matched control population. These findings suggest that there are significant opportunities for ED intervention and referral to treatment both prior to and following an opioid-related ED visit in this patient population.

Intravenous antibiotics at the index emergency department visit as an independent risk factor for hospital admission at the return visit within 72 hours.

IntroductionAlthough infection was the most common symptom in patients returning to the ED, whether intravenous antibiotic administration at the index visit could serve as an indicator of patients with infectious diseases at high risk for hospital admission after returning to the ED within a short period of time remains unclear. The study aimed to investigate the potential risk factors for hospital admission in patients returning to the ED within 72 hours with a final diagnosis of infectious diseases.Material and methodsThis retrospective cohort study analyzed return visits to the ED from January to December 2019. Adult patients aged >20 years who had a return visit to the ED within 72 hours with an infectious disease were included herein. In total, 715 eligible patients were classified into the intravenous antibiotics and non-intravenous antibiotics group (reference group). The outcome studied was hospital admission to general ward and intensive care unit (ICU) at the return visits.ResultsPatients receiving intravenous antibiotics at index visits had significantly higher risk—approximately two times—for hospital admission at the return visits than those did not (adjusted odds ratio = 2.47, 95% CI = 1.34–4.57, p = 0.004). For every 10 years increase in age, the likelihood for hospital admission increased by 38%. Other factors included abnormal respiratory rate and high C-reactive protein levels.ConclusionsIntravenous antibiotic administration at the index visit was an independent risk factor for hospital admission at return visits in patients with an infection disease. Physicians should consider carefully before discharging patients receiving intravenous antibiotics.

Profiles, Correlates and Outcomes Among Patients Experiencing an Onset of Mental Disorder Based on Outpatient Care Received Following Index Emergency Department Visits.

This 5-year longitudinal study evaluated patients with an onset of mental disorder (MD) following index emergency department (ED) visits, in terms of (1) patient profiles based on 12-month outpatient follow-up care received, (2) sociodemographic and clinical correlates, and (3) adverse health outcomes for the subsequent 2 years. Data from administrative databases were collected for 2541 patients with an onset of MD, following discharge from Quebec ED. Latent class analysis was performed to identify patient profiles based on the adequacy of follow-up care after ED discharge. Bivariate analyses examined associations between class membership and sociodemographic and clinical correlates, high ED use (3 + visits/yearly), hospitalizations, and suicidal behaviors. Five classes of patients were identified. Class 1, the smallest, labeled "patient psychiatrist only," included mainly young patients with serious MD. Classes 2 and 3, roughly 20%, were labeled "high use of patient general practitioner (GP) and psychiatrist" and "low use of patient GP and psychiatrist," respectively. Both included patients with complex MD, but Class 2 had more women and older patients with chronic physical illnesses. The 2 largest classes were labeled "no usual patient service provider" (Class 5) and "patient GP only" (Class 4). Class 5 included more younger men with substance-related disorders, while Class 4 had the older patients living in rural areas, many with common MD and chronic physical illnesses. Class 3 patients had the poorest outcomes, followed by Classes 1 and 2, while Classes 4 and 5 had the best outcomes. Results revealed that nearly 40% of patients experiencing an onset of MD received little or no outpatient care following ED discharge. Higher severity or complexity of MD and, to a lesser extent, no or low GP follow-up may explain these adverse outcomes. More adequate, continuous care, including collaborative care, is needed for these vulnerable, high-needs patients.

Dental hygienists' scope of practice regulations and preventable non-traumatic dental emergency department visits: A cross-sectional study of 10 U.S. states.

As emergency department (ED) visits for non-traumatic dental complaints continue to rise in the United States (U.S.), some states are implementing initiatives to expand access to the oral health workforce. This study examines the associations between the 2014 Dental Hygiene Professional Practice Index (DHPPI) and preventable dental ED visits. In 2020, we used ED data from 10 U.S. states and ordinary least squares models to examine the relationship between the states' DHPPI scores and preventable dental ED use.We stratified regressions by age to examine this relationship across different age cohorts and introduced interaction terms to assess the same relationship among rural and urban residents. On average, 23.8% of all non-traumatic dental ED visits were identified as preventable. Controlling for other factors, a one-point increase in DHPPI scores was associated with a decrease of 0.01 (95% CI -0.03, -0.02) preventable dental ED visits per 1000 county population in each year-quarter. In the age-stratified models, the strength of the association between DHPPI scores and preventable dental ED visits was higher in the 20 to 34 (-0.03, 95% CI -0.04, -0.02), and the 35 to 50 age cohorts (-0.17, 95% CI -0.00, -0.00). U.S. states with DHPPI scores below 60saw significantly higher preventable dental ED visits among rural residents. This studydemonstratesthat stringent state policiesregarding the dental hygienist workforce are associated with higher preventable dental ED visits in the U.S. Policy makers and stake holders must address the scope of practice policies to alleviate the burden of access to oral healthcare.
