10-Year Trends of Emergency Department Visits, Wait Time, and Length of Stay among Adults with Mental Health and Substance use Disorders in the United States.

This study examined if there was a change in the number of Emergency Department (ED) visits, wait time, and length of stay among adults with mental health and substance use disorders (MHSUD) in the United States from 2006 to 2015. From the National Hospital Ambulatory Medical Care Survey, a total of 17,488 ED visits by adults with MHSUD were identified. Linear regression and negative binomial regression analyses were conducted to assess statistically significant changes in trends of ED visits, wait time, and length of stay. Results indicated that ED visits by adults with MHSUD increased by 30.6% from 2006 to 2015. Wait time of ED visits by adults with MHSUD decreased for the same time period; however, length of stay did not change. Also, there were some differences in trends of wait time and length of stay by diagnosis. Specifically, wait time of ED visits by adults with psychotic disorders did not decrease. Length of stay of ED visits by adults with anxiety disorders statistically significantly increased from 2006 to 2015. More effort is needed to improve the quality of ED care for adults with MHSUD. In such an effort, diagnoses should be taken into consideration.

Monitoring Sexual Violence Trends in Emergency Department Visits Using Syndromic Data From the National Syndromic Surveillance Program-United States, January 2017-December 2019.

Objectives. To report trends in sexual violence (SV) emergency department (ED) visits in the United States.Methods. We analyzed monthly changes in SV rates (per 100 000 ED visits) from January 2017 to December 2019 using Centers for Disease Control and Prevention's National Syndromic Surveillance Program data. We stratified the data by sex and age groups.Results. There were 196 948 SV-related ED visits from January 2017 to December 2019. Females had higher rates of SV-related ED visits than males. Across the entire time period, females aged 50 to 59 years showed the highest increase (57.33%) in SV-related ED visits, when stratified by sex and age group. In all strata examined, SV-related ED visits displayed positive trends from January 2017 to December 2019; 10 out of the 24 observed positive trends were statistically significant increases. We also observed seasonal trends with spikes in SV-related ED visits during warmer months and declines during colder months, particularly in ages 0 to 9 years and 10 to 19 years.Conclusions. We identified several significant increases in SV-related ED visits from January 2017 to December 2019. Syndromic surveillance offers near-real-time surveillance of ED visits and can aid in the prevention of SV.

Trends in Emergency Department Visits for Mental Health Disorder Diagnoses Before and During the COVID-19 Pandemic: A Retrospective Cohort Study 2016-2021

Background: As the pandemic started, Saudi Arabia applied extreme measures in responses to the public health crises. These control measures have adversely affected individuals with reported psychological illnesses such as depression, and anxiety. We aimed to describe trends, and gender-age differences in proportions of psychiatric Emergency department (ED) visits from 2016 to 2021 in two large hospitals in Saudi Arabia.Methods: This is a retrospective cohort study using data from electronic health records in the Ministry of National Guard Health Affairs’ (MNG-HA) in two major hospitals in Saudi Arabia. Individuals aged ≥12 years diagnosed with mental disorder from January 2016 to May 31, 2021, registered in MNG-HA hospitals system were included in the study.Outcomes: A total of 1171 ED psychiatric visits (52% female, 48% male). A constant annual increase in the number of psychiatric ED visits before the pandemic from 2016 to 2019 (2.91%, 6.17%, 9.64%, and 15.25%) was observed. While nearly 42% of total psychiatric visits for the study period occurred during the pandemic 2020-2021. During the pandemic, psychiatric ED visits were significantly higher in females (adjusted OR 1.46; CI 1.14, 1.86) than males. During the pandemic, generalized anxiety disorder was the most common psychiatric ED disorder with reported increase of visits by 48.44% (p-value 0.007).Interpretation: ED psychiatric visit rates have consistently increased before and during the pandemic. During the pandemic, female at greater risk of seeking psychiatric ED services than male. Interventions for mental health related disorders are urgently needed for preventing mental health problems.Funding: None to declare. Declaration of Interest: None to declare. Ethical Approval: Biomedical ethics committee of King Abdullah International Medical Research Center (KAIMRC) approved this study (JED-21-427780-99596)

Trends in Emergency Department Visits and Hospital Admissions in Health Care Systems in 5 States in the First Months of the COVID-19 Pandemic in the US

As coronavirus disease 2019 (COVID-19) spread throughout the US in the early months of 2020, acute care delivery changed to accommodate an influx of patients with a highly contagious infection about which little was known. To examine trends in emergency department (ED) visits and visits that led to hospitalizations covering a 4-month period leading up to and during the COVID-19 outbreak in the US. This retrospective, observational, cross-sectional study of 24 EDs in 5 large health care systems in Colorado (n = 4), Connecticut (n = 5), Massachusetts (n = 5), New York (n = 5), and North Carolina (n = 5) examined daily ED visit and hospital admission rates from January 1 to April 30, 2020, in relation to national and the 5 states' COVID-19 case counts. Time (day) as a continuous variable. Daily counts of ED visits, hospital admissions, and COVID-19 cases. A total of 24 EDs were studied. The annual ED volume before the COVID-19 pandemic ranged from 13 000 to 115 000 visits per year; the decrease in ED visits ranged from 41.5% in Colorado to 63.5% in New York. The weeks with the most rapid rates of decrease in visits were in March 2020, which corresponded with national public health messaging about COVID-19. Hospital admission rates from the ED were stable until new COVID-19 case rates began to increase locally; the largest relative increase in admission rates was 149.0% in New York, followed by 51.7% in Massachusetts, 36.2% in Connecticut, 29.4% in Colorado, and 22.0% in North Carolina. From January through April 2020, as the COVID-19 pandemic intensified in the US, temporal associations were observed with a decrease in ED visits and an increase in hospital admission rates in 5 health care systems in 5 states. These findings suggest that practitioners and public health officials should emphasize the importance of visiting the ED during the COVID-19 pandemic for serious symptoms, illnesses, and injuries that cannot be managed in other settings.

Trends in Emergency Department Visits for Contact Sports-Related Traumatic Brain Injuries Among Children - United States, 2001-2018.

During 2010-2016, there were an average of 283,000 U.S. emergency department (ED) visits each year among children for sports and recreation-related traumatic brain injuries (SRR-TBIs); approximately 45% of these SRR-TBIs were associated with contact sports (1). Although most children with an SRR-TBI are asymptomatic within 4 weeks, there is growing concern about potential long-term effects on a child's developing brain (2). This has led to calls to reduce the risk for traumatic brain injuries (TBIs) among child athletes, resulting in the introduction of state policies and the institution of safety rules (e.g., age and contact restrictions) for some sports programs. To assess changes in the incidence of ED-related SRR-TBI among children, CDC analyzed data from the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP) for the period 2001-2018. After more than a decade of increasing rates, the rate of contact sports-related TBI ED visits declined 32% from 2012 to 2018. This reduction was primarily the result of a decline in football-related SRR-TBI ED visits during 2013-2018. Decreased participation in tackle football (3) and implementation of contact limitations (4) were likely contributing factors to this decline. Public health professionals should continue to expand efforts to address SRR-TBIs in football, which is the sport with the highest incidence of TBI, and identify effective prevention strategies for all sports to reduce TBIs among children.

Increasing Allergy-Related Emergency Department Visits in the United States, 2007 to 2015

Allergic reactions, angioedema, and anaphylaxis are commonly treated in the emergency department (ED). Contemporary evidence suggests that these conditions may be increasing in the United States. To evaluate the contemporary epidemiology and trends of ED visits for allergic reactions, angioedema, and anaphylaxis in the United States from 2007 to2015. Using de-identified data from the National Hospital Ambulatory Medical Care Survey from 2007 to 2015, we identified cases of acute allergic reactions, angioedema, and anaphylaxis through International Classification of Diseases, 9th Revision, Clinical Modification codes and conducted a retrospective analysis of rates and trends of these allergy-related ED visits. There was a 14% overall increase in allergy-related ED visits between 2007 and 2015. Approximately 10 million ED visits in this time frame were associated with allergy-related conditions accounting for 0.85% (95% CI, 0.79-0.90) of all ED visits in the United States. Almost 3% of allergy-related ED visits were coded as anaphylaxis of which 46.1% (95% CI, 27.5-64.6) received epinephrine. Patients younger than 10 years had a higher relative risk (1.3; 95% CI, 1.0-1.6; P= .027) of allergy-related ED visits per 1000 ED visits than patients 65 years and older, and women also had a higher relative risk (1.4; 95% CI, 1.2-1.5; P < .001) than men. Allergy-related ED visits increased 14% from 2007 to 2015, with the highest relative risk occurring in patients younger than 10 years. These data provide further evidence of increasing allergic conditions in the United States.

Temporal Trends of Emergency Department Visits of Patients with Atrial Fibrillation: A Nationwide Population-Based Study.

We aimed to describe temporal trends in emergency department (ED) visits of patients with atrial fibrillation (AF) over 12 years. A repeated cross-sectional analysis of ED visits in AF patients using the Korean nationwide claims database between 2006 and 2017 were conducted. We identified AF patients who had ≥1 ED visits. The incidence of ED visits among total AF population, cause of ED visit, and clinical outcomes were evaluated. During 12 years, the annual numbers of AF patients who attended ED at least once a year continuously increased (40,425 to 99,763). However, the annual incidence of ED visits of AF patients was stationary at about 30% because the number of total AF patients also increased during the same period. The most common cause of ED visits was cerebral infarction. Although patients had a higher risk profile over time, the 30-day and 90-day mortality after ED visit decreased over time. ED visits due to ischemic stroke, intracranial hemorrhage, and myocardial infarction decreased, whereas ED visits due to AF, gastrointestinal bleeding, and other major bleeding slightly increased among total AF population over 12 years. A substantial proportion of AF patients attended ED every year, and the annual numbers of AF patients who visited the ED significantly increased over 12 years. Optimized management approaches in a holistic and integrated manner should be provided to reduce ED visits of AF patients.

Trends in Emergency Department Visits and Inpatient Admissions for Hyperglycemic Crises in Adults With Diabetes in the U.S., 2006-2015.

OBJECTIVETo report U.S. national population-based rates and trends in diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS) among adults, in both the emergency department (ED) and inpatient settings.RESEARCH DESIGN AND METHODSWe analyzed data from 1 January 2006 through 30 September 2015 from the Nationwide Emergency Department Sample and National Inpatient Sample to characterize ED visits and inpatient admissions with DKA and HHS. We used corresponding year cross-sectional survey data from the National Health Interview Survey to estimate the number of adults ≥18 years with diagnosed diabetes to calculate population-based rates for DKA and HHS in both ED and inpatient settings. Linear trends from 2009 to 2015 were assessed using Joinpoint software.RESULTSIn 2014, there were a total of 184,255 and 27,532 events for DKA and HHS, respectively. The majority of DKA events occurred in young adults aged 18–44 years (61.7%) and in adults with type 1 diabetes (70.6%), while HHS events were more prominent in middle-aged adults 45–64 years (47.5%) and in adults with type 2 diabetes (88.1%). Approximately 40% of the hyperglycemic events were in lower-income populations. Overall, event rates for DKA significantly increased from 2009 to 2015 in both ED (annual percentage change [APC] 13.5%) and inpatient settings (APC 8.3%). A similar trend was seen for HHS (APC 16.5% in ED and 6.3% in inpatient). The increase was in all age-groups and in both men and women.CONCLUSIONSCauses of increased rates of hyperglycemic events are unknown. More detailed data are needed to investigate the etiology and determine prevention strategies.

Trends in Emergency Department Visits among Adolescents with Abnormal Uterine Bleeding.

To explore trends over time in the utilization of the Emergency Department (ED) for adolescents with abnormal uterine bleeding (AUB). Retrospective cross-sectional study. Nationwide Emergency Department Sample database (Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality, Rockville, MD). Subset of adolescents aged 10-19years from overall cohort of women aged 10-49years. All ED visits from 2010-2014 for which International Classification of Diseases, ninth revision codes for AUB were listed as the principal diagnosis were compared. Health insurance coverage, demographic factors, hospital characteristics, comorbid anemia, and comorbid bleeding disorders were explored. Number of visits, ED disposition, blood transfusions, and billing for pelvic ultrasound. There were an estimated 262,939 ED visits nationally for women aged 10-49years for AUB in 2014. Of these, 12.7% (33,511/262,939) were from adolescents aged 10-19years. The number of adolescent visits with an AUB diagnosis declined by 11% from 2010-2014 (37,642 vs 33,511; P=.026), while visits by patients aged 20-49 did not change significantly (215,309 vs 229,428; P=.19). The number of adolescent visits for which Medicaid was the primary payer increased slightly, from 17,283 to 18,785, from 2010 to 2014 (P=.152), while the number using self-pay decreased from 8769 (23.4%) in 2010 to 5146 (15.4%) in 2014 (P<.0001). ED visits among adolescents with AUB decreased from 2010 to 2014. There was a sharp reduction in the number of visits funded by self-pay and a slight increase in visits funded by Medicaid.

Impact of the COVID-19 Pandemic on Emergency Room Attendances: Experience at a Tertiary Care Centre in Pakistan

Objective: Since the emergence of the COVID-19 pandemic, several reports have shown markedly reduced Emergency Department utilization. We aimed to examine the trends in Emergency Department visits during the early phase of the COVID-19 pandemic in a tertiary care center in Pakistan. Methods: A retrospective, observational analysis of Emergency Department visits was performed at Shifa International hospital over the 3-month study period (March to May 2020) in the early phase of the COVID-19 pandemic. The same 3-month period in 2019 was used as a reference. Total visits, as well as priority level at arrival, diagnosis, and disposition at discharge along with age and gender, were recorded and compared, and the changes in Emergency Department visits were assessed descriptively. Results: During the study period, the total Emergency Department volume was 40% lower than that of 2019. Percentage of hospitalizations increased to 32.7 % (of all Emergency Department visits) in 2020: a 4.1% rise (p-value

Rising Trends in Emergency Department Visits Associated With Hepatitis C Virus Infection in the United States, 2006-2014.

Emergency departments (EDs) are critical settings for hepatitis C care in the United States. We assessed trends and characteristics of hepatitis C-associated ED visits during 2006-2014. We used data from the 2006-2014 Nationwide Emergency Department Sample to estimate numbers, rates, and costs of hepatitis C-associated ED visits, defined by either first-listed diagnosis of hepatitis C or all-listed diagnosis of hepatitis C. We assessed trends by demographic characteristics, liver disease severity, and patients' disposition by using joinpoint analysis, and we calculated the average annual percentage change (AAPC) from 2006 to 2014. During 2006-2014, the rate per 100 000 visits of first-listed and all-listed hepatitis C-associated ED visits increased significantly from 10.1 to 25.4 (AAPC = 13.0%; P < .001) and from 484.4 to 631.6 (AAPC = 3.4%; P < .001), respectively. Approximately 70% of these visits were made by persons born during 1945-1965 (baby boomers); 30% of visits were made by Medicare beneficiaries and 40% by Medicaid beneficiaries. Significant rate increases were among visits by baby boomers (first-listed: AAPC = 13.8%; all-listed: AAPC = 2.6%), persons born after 1965 (first-listed: AAPC = 14.3%; all-listed: AAPC = 9.2%), Medicare beneficiaries (first-listed: AAPC = 18.0%; all-listed: AAPC = 3.9%), and persons hospitalized after ED visits (first-listed: AAPC = 20.0%; all-listed: AAPC = 2.3%; all P < .001). Increasing proportions of compensated cirrhosis were among visits by baby boomers (first-listed: AAPC = 11.5%; all-listed: AAPC = 6.3%). Annual hepatitis C-associated total ED costs increased by 400.0% (first-listed) and 192.0% (all-listed) during 2006-2014. Public health efforts are needed to address the growing burden of hepatitis C care in the ED.

Customizing ESSENCE Queries for Select Mental Health Sub-indicators

ObjectiveEmergency department (ED) visits related to mental health (MH) disorders have increased since 2006 (1), indicating a potential burden on the healthcare delivery system. Surveillance systems has been developed to identify and understand these changing trends in how EDs are used and to characterize populations seeking care. Many state and local health departments are using syndromic surveillance to monitor MH-related ED visits in near real-time. This presentation describes how queries can be created and customized to identify select MH sub-indicators (for adults) by using chief complaint text terms and diagnoses codes. The MH sub-indicators examined are mood and depressive disorders, schizophrenic disorders, and anxiety disorders. Wider adoption of syndromic surveillance for characterizing MH disorders can support long-term planning for healthcare resources and service delivery.IntroductionSyndromic surveillance systems, although initially developed in response to bioterrorist threats, are increasingly being used at the local, state, and national level to support early identification of infectious disease and other emerging threats to public health. To facilitate detection, one of the goals of CDC’s National Syndromic Surveillance Program (NSSP) is to develop and share new sets of syndrome codes with the syndromic surveillance Community of Practice. Before analysts, epidemiologists, and other practitioners begin customizing queries to meet local needs, especially monitoring ED visits in near-real time during public health emergencies, they need to understand how syndromes are developed.More than 4,000 hospital routinely send data to NSSP’s BioSense Platform, representing about 55 percent of ED visits in the United States (2). The platform’s surveillance component, ESSENCE,* is a web-based application for analyzing and visualizing prediagnostic hospital ED data. ESSENCE’s Chief Complaint Query Validation (CCQV) data source, which is a national-level data source with access to chief complaint (CC) and discharge diagnoses (DD) from reporting sites, was designed for testing new queries.MethodsWe used ESSENCE CCQV to query weekly data for the nine week period from the first quarter of 2018 and looked at three common MH sub-indicators: mood and depressive disorders, schizophrenic disorders, and anxiety disorders. We developed four query types for each MH sub-indicator. Query-1 focused on DD codes; query-2 focused on CC text terms; query-3 focused on a combination of CC, DD, and no exclusion for mental health co-morbidity; and query-4 focused on a combination of CC and DD and excluded mental health co-morbidity. We also examined the summary distribution of CC texts to identify keywords related to MH sub-indicators.For mood and depressive disorders, we queried ICD-9 codes 296, 311; ICD-10 codes F30–F39; CC text terms for words “depressive disorder,” bipolar disorder,” “mood disorder,” “depression,” “manic episodes,” and “psychotic.” For schizophrenic disorders, we queried ICD-9 codes 295; ICD-10 codes F20–F29; CC text terms for words “psychosis,” “psychotic,” “schizo,” “delusional,” “paranoid,” “auditory,” “hallucinations,” and “hearing voices.” For anxiety disorders, we queried ICD-9 codes 300, 306, 307, 308, 309; ICD-10 codes F40–F48; CC text terms for words “anxiety,” “anexiy,” “aniety,” “aniexty,” “ansiety,” “anxety,” “anxity,” “anxiety,” “phobia,” and “panic attack.”ResultsWe identified 2.3 million average weekly ED visits for the 9-week period queried. Table 1 shows average weekly ED visits of select MH sub-indicators from the four query types. Because query 4 focused on specific MH outcomes and excluded MH co-morbidities, the average weekly ED visit for all three sub-indicators was almost half that of query 3, which focused on broader concepts by including MH co-morbidities. Among mood and depressive disorders, query 4 identified on average 23,352 ED visits per week versus 45,504 visits per week for query 3. Similarly, for schizophrenic disorders and anxiety disorders, query 4 identified on average 4,988 and 32,790 visits per week compared with 9,816 and 53,868 visits, respectively, for query 3. Further, more MH-related visits were identified using the DD-coded query (query 1) than CC-based text terms (query 2).ConclusionsAnalysts can benefit from having queries on select sub-indicators readily available and can use these to facilitate routine MH-related monitoring of ED visits, or customize the queries by including local text terms. Consistent with our previous work (3), this analysis demonstrated that MH-related ED visits are more likely to be found in DD codes than in CC alone.* Electronic Surveillance for the Early Notification of Community-based EpidemicsReferences[1] Weiss AJ, Barrett ML, Heslin KC , Stocks C.

EMS Heroin Overdoses with Refusal to Transport &amp; Impacts on ED Overdose Surveillance

ObjectiveThe aim of this project was to explore changing patterns in patient refusal to transport by emergency medical services for classified heroin overdoses and possible implications on heroin overdose surveillance in Kentucky.IntroductionAs a Centers for Disease Control and Prevention Enhanced State Opioid Overdose Surveillance (ESOOS) funded state, Kentucky started utilizing Emergency Medical Services (EMS) data to increase timeliness of state data on drug overdose events in late 2016. Using developed definitions of heroin overdose for EMS emergency runs, Kentucky analyzed the patterns of refused/transported EMS runs for both statewide and local jurisdictions. Changes in EMS transportation patterns of heroin overdoses can have a dramatic impact on other surveillance systems, such as emergency department (ED) claims data or syndromic surveillance (SyS) data.MethodsAs part of the ESOOS grant, Kentucky receives all emergency-only EMS runs monthly from Kentucky Board for Emergency Medical Services, Kentucky State Ambulance Reporting System data. Heroin cases were classified based on text and medications (Narcan) administered, with comparisons to historic data discussed elsewhere (Rock &amp; Singleton, 2018). Transportation classifications are based on EMS standard elements defining treatment with transportation vs refusal to transport to hospital and canceled runs were excluded. Initial analysis included trend analysis at state and local levels, as well as demographic comparisons of refusal vs transported heroin overdose encounters.ResultsStatewide trends in EMS heroin overdoses with refusal transport significantly increased from 5% (n=42) in 2016 quarter three to 22% (n=290) in 2018 quarter two (Fig 1). Initial demographic analysis does not show any significant difference between refusals/transported for age, gender, or race. However, there are significant differences among geographic regions in Kentucky with heroin encounter refusal proportion ranging from 3%-48% in 2018 quarter two. Specifically, one urban area (Fig 2) shows the change in proportion of refusal increasing from 15% (n=23) in 2016 quarter three to 47% (n=110) in 2018 quarter two. In this geographic area, combined refused/transported EMS heroin overdoses compared to traditional ED data demonstrates opposing heroin overdose patterns for the same local with EMS showing and increasing trend overtime and ED showing a decreasing trend (Fig 3).ConclusionsTraditional public health surveillance for heroin overdose has historically relied on ED billing data, though agencies are starting to use syndromic surveillance, too (Vivolo-Kantor et al., 2016). These systems share similar underlying ED data, albeit with different components, quality, and limitations. However, in terms of the overdose epidemic, both are limited to only heroin overdoses that result in ED hospital encounters. The recent drastic increase in refused transport can have significant impacts on heroin surveillance. Jurisdictions relying on SyS or ED data for monitoring overdose patterns and/or evaluating interventions may be significantly underestimating acute overdose occurrence in the population. This analysis highlights the importance of this preclinical data source in surveillance of the heroin epidemic.ReferencesRock, P. J., &amp; Singleton, M. D. (2018).

Trends of ED visits, admissions, and deaths for pediatric traumatic brain injury comparing sport and non-sport mechanisms

BackgroundTraumatic brain injuries (TBI) in children result in significant morbidity and mortality. There are many mechanisms, both sport and non-sport related, which cause these injuries. Studies have reported that Emergency Department (ED) visits for pediatric TBI caused by sports are increasing; however, no subsequent study has evaluated the trend in non-sport TBI. The objective of this study was to evaluate ED visits, admissions, and deaths for non-sport TBI compared to those caused by sports.MethodsA retrospective study of children 5–19 years of age was performed at a pediatric, level 1 trauma center from 2002 to 2012. Subjects with a primary or secondary diagnosis of TBI were identified from the hospital’s trauma registry, and mechanism of injury, disposition, injury severity score, and length of stay were recorded. Frequencies were used to characterize the population, Chi-square analysis was performed to determine differences between groups, and linear trend lines were calculated for sport-related and non-sport TBI by year.ResultsThirteen thousand two hundred ninty one subjects were seen in the ED between 2002 and 2012 for a TBI; 9527 (72%) were from a non-sport mechanism, and 3764 (28%) were from a sport mechanism. Subjects with a non-sport TBI were more likely to be younger (p < 0.001), African American (p < 0.001), and have Medicare/Medicaid (p < 0.001). Subjects with a non-sport TBI were admitted to the hospital 15% of the time, and subjects with a sport-related TBI were admitted 10% of the time (p < 0.001). When evaluating all TBI by mechanism of injury, sport had the lowest injury severity score (mean 4.4) and the shortest length of stay (mean 1.6 days) of any mechanism. There were six deaths reported from non-sport TBI and none from sport-related TBI. ED visits for sport-related TBI increased 92%, and non-sport TBI increased 22% over 10 years. There was a peak in TBI, in both groups, seen in 2009.ConclusionsED visits for both sport and non-sport TBI have increased over the past 10 years. TBI from a non-sport mechanism was more likely to result in hospitalization or death. Prevention efforts should be expanded to include all high-risk TBI mechanisms, not just sports.

Seeking Help: Trends in Emergency Department Visits Among Women With Postpartum Mental Disorders [18D

Urgent care centres reduce emergency department and primary care same-day visits: a natural experiment.

The aim of this study is to evaluate the impact of urgent care centres' (UCCs) implementation on emergency department (ED) and same-day visits in primary care in a Chilean public healthcare network. Quasi-experimental design study assessing changes in patient visits after UCC implementation in a local health district. Ten family health centres (FHC), nine UCCs and three EDs in the Talcahuano Health District, Chile. A total of 1603055 same-day visits to FHC, 1528319 visits to UCCs and 1727429 visits to EDs, monthly grouped, from 2008 to 2014. Data were obtained from the Monthly Statistical Register Database. We used quasi-experimental methods to evaluate the impact of UCC implementation on ED visits and same-day visits to FHC. We used a difference-in-difference analysis with seasonal adjustments to control potential confounders. We used a triple difference model to test for potential short-term effects. We used as an intervention a group of FHCs and EDs that implemented UCCs from 2008 to 2014 and, as a comparison group, the FHCs and EDs that implemented UCCs before that period. We observed a 5.70% (95% CI: -11.05 to -0.35) decrease in the same-day visits rate to FHCs and a 2.69% (95% CI: -3.96 to -1.43) reduction in ED visits after UCC implementation. The negative trend in same-day visits was more pronounced in children and adolescents (-14.18%; 95% CI: -20.10 to -8.25). The negative trend in ED visits was more pronounced in adult (-4.15%; 95% CI: -5.46 to -2.83) and elderly population (-2.24%; 95% CI: -4.00 to -0.48). We also confirmed that our results are not driven by transient short-term effects after the intervention. UCC implementation reduced ED visits. However, they also reduced same-day visits to primary care centres. This could have a negative impact on the quality of primary care provided.

Incidence, Admission Rates, and Predictors, and Economic Burden of Adult Emergency Visits for Acute Pancreatitis: Data From the National Emergency Department Sample, 2006 to 2012.

Acute pancreatitis (AP) is the most common gastroenterology-related reason for hospital admission, and a major source of morbidity and mortality in the United States. This study examines the National Emergency Database Sample, a large national database, to analyze trends in emergency department (ED) utilization and costs, risk factors for hospital admission, and associated hospital costs and length of stay (LOS) in patients presenting with AP. The National Emergency Database Sample (2006 to 2012) was evaluated for trends in ED visits, ED charges, hospitalization rates, hospital charges, and hospital LOS in patients with primary diagnosis of AP (further subcategorized by age and etiology). A survey logistic-regression model was used to determine factors predictive of hospitalization. A total of 2,193,830 ED visits were analyzed. There was a nonsignificant 5.5% (P=0.07) increase in incidence of ED visits for AP per 10,000 US adults from 2006 to 2012, largely driven by significant increases in ED visits for AP in the 18 to <45 age group (+9.2%; P=0.025), AP associated with alcohol (+15.9%; P=0.001), and AP associated with chronic pancreatitis (+59.5%; P=0.002). Visits for patients aged ≥65 decreased over the time period. Rates of admission and LOS decreased during the time period, while ED and inpatient costs increased (62.1%; P<0.001 and 7.9%; P=0.0011, respectively). Multiple factors were associated with increased risk of hospital admission from the ED, with the strongest predictors being morbid alcohol use [odds ratio (OR), 4.53; P<0.0001], advanced age (age>84 OR, 3.52; P<0.0001), and smoking (OR, 1.75; P<0.0001). Despite a relative stabilization in the overall incidence of ED visits for AP, continued increases in ED visits and associated costs appear to be driven by younger patients with alcohol-associated and acute on chronic pancreatitis. While rates of hospitalization and LOS are decreasing, associated inflation-adjusted costs are rising. In addition, identified risk factors for hospitalization, such as obesity, alcohol use, and increased age, should be explored in further study for potential use in predictive models and clinical improvement projects.

Characteristics and Trends of Emergency Department Visits in the United States (2010–2014)

It is important that policy makers, health administrators, and emergency physicians have up-to-date statistics on the most common diagnoses of patients seen in the emergency department (ED). We sought to describe the changes that occurred in ED visits from 2010 through 2014 and to describe the frequency of different ED diagnoses. This is a retrospective analysis of ED visit data from the National Emergency Department Sample from 2010 through 2014. Visits were stratified by age, sex, insurance status, disposition, diagnosis, and diagnostic category. We calculated the total annual ED visits and the ED visit rates by diagnoses and diagnostic categories. Between 2010 and 2014, the number of U.S. ED visits increased from 128.9 million to 137.8 million. The rate of ED Visits per 1000 persons increased from 416.92 (95% confidence interval [CI] 399.47-434.37) in 2010 to 432.51 (95% CI 411.51-453.61) in 2014 (p=0.0136). ED visits grew twice as quickly (1.7%) as the overall population (0.7%). The most common reason for an ED visit was abdominal pain (11.75% [95% CI 11.61-11.89]). This was followed by mental health problems (4.45% [95% CI 4.19-4.72]). The number of ED visits in the United States continues to increase faster than the rate of population growth. Abdominal problems and mental health issues, including substance abuse, were the most common reasons for an ED visit in 2014.
