Project description:To examine trends and correlates of cannabis-involved emergency department (ED) visits in the United States from 2004 to 2011.Data were obtained from the 2004 to 2011 Drug Abuse Warning Network. We analyzed trend in cannabis-involved ED visits for persons aged ?12 years and stratified by type of cannabis involvement (cannabis-only, cannabis-polydrug). We used logistic regressions to determine correlates of cannabis-involved hospitalization versus cannabis-involved ED visits only.Between 2004 and 2011, the ED visit rate increased from 51 to 73 visits per 100,000 population aged ?12 years for cannabis-only use (P value for trend?=?0.004) and from 63 to 100 for cannabis-polydrug use (P value for trend?<?0.001). Adolescents aged 12-17 years showed the largest increase in the cannabis-only-involved ED visit rate (rate difference?=?80 per 100,000 adolescents). Across racial/ethnic groups, the most prevalent ED visits were noted among non-Hispanic blacks. Among cannabis-involved visits, the odds of hospitalization (vs ED visits only) increased with age strata compared with age 12 to 17 years.These findings suggest a notable increase in the ED visit numbers and rates for both the use of cannabis-only and cannabis-polydrug during the studied period, particularly among young people and non-Hispanic blacks.
Project description:In recent years, there has been an increase in poisoning-related emergency department (ED) visits. This study examines trends in ED resource utilization for poisoning-related visits over time. A retrospective review of data from the National Hospital Ambulatory Medical Care Survey, 2003-2011, was conducted. All ED visits with a reason for visit or ICD-9 code related to poisoning were included. We examined the number of ED visits and resources used including diagnostic studies and procedures performed, medications provided, admission rates, and length of stay. The proportion of visits involving resource use was tabulated and trends analyzed using survey-weighted logistic regression, grouping into 2-year periods to ensure adequate sample size. Of an estimated 843 million ED visits between 2003 and 2011, 8 million (0.9 %) were related to poisoning. Visits increased from 1.8 million (0.8 %) visits in 2003-2004 to 2.9 million (1.1 %) visits in 2010-2011, p = 0.001. Use of laboratory studies, EKGs, plain radiographs, and procedures remained stable across the study period. CT use was more than doubled, increasing from 5.2 to 13.7 % of visits, p = 0.001. ED length of stay increased by 35.5 % from 254 to 344 min, p = 0.001. Admission rates increased by 45.3 %, from 15.0 to 21.8 %, p = 0.046. Over the entire study period, 52.0 % of poisoned patients arrived via ambulance, and 3.0 % of patients had been discharged from the hospital within the previous 7 days. Poisoning-related ED visits increased over the 8-year study period; poisonings are resource-intensive visits and require increasingly longer lengths of ED stay or hospital admission.
Project description:Study objectivePrevious studies have shown that charges for inpatient and clinic procedures vary substantially; however, there are scant data on variation in charges for emergency department (ED) visits. Outpatient ED visits are typically billed with current procedural terminology-coded levels to standardize the intensity of services received, providing an ideal element on which to evaluate charge variation. Thus, we seek to analyze the variation in charges for each level of ED visits and examine whether hospital- and market-level factors could help predict these charges.MethodsUsing 2011 charge data provided by every nonfederal California hospital to the Office of Statewide Health Planning and Development, we analyzed the variability in charges for each level of ED visits and used linear regression to assess whether hospital and market characteristics could explain the variation in charges.ResultsCharges for each ED visit level varied widely; for example, charges for a level 4 visit ranged from $275 to $6,662. Government hospitals charged significantly less than nonprofit hospitals, whereas hospitals that paid higher wages, served higher proportions of Medicare and Medicaid patients, and were located in areas with high costs of living charged more. Overall, our models explained only 30% to 41% of the between-hospital variation in charges for each level of ED visits.ConclusionOur findings of extensive charge variation in ED visits add to the literature in demonstrating the lack of systematic charge setting in the US health care system. These widely varying charges affect the hospital bills of millions of uninsured patients and insured patients seeking care out of network and continue to play a role in many aspects of health care financing.
Project description:Increasing use of the emergency department (ED) is well documented, but little is known about the type and severity of ED visits or their distribution across safety-net and non-safety-net hospitals. We examined the rates of high-intensity ED visits--characterized by their use of advanced imaging, consultations with specialists, the evaluation of multiple systems, and highly complex medical decision making--by patients with a severe, potentially life-threatening illness in California from 2002 through 2009. Total annual ED visits increased by 25 percent, from 9.0 million to 11.3 million, but high-intensity ED visits nearly doubled, increasing 87 percent from 778,000 to 1.5 million per year. The percentage of ED visits with high-intensity care increased from 9 percent to 13 percent (a relative increase of 44 percent). Annual ED admissions increased by 39 percent overall; most of this increase was attributable to high-intensity ED admissions, which increased by 88 percent. Safety-net EDs experienced an increase in high-intensity visits of 157 percent, compared to an increase of 61 percent at non-safety-net EDs. These findings suggest a trend toward intensification of ED care, particularly at safety-net hospitals, whose patients may have limited access to care outside the ED.
Project description:ObjectiveTo determine the association between prescription drug monitoring program (PDMP) implementation and emergency department (ED) visits involving opioid analgesics.MethodsRates of ED visits involving opioid analgesics per 100,000 residents were estimated from the Drug Abuse Warning Network dataset for 11 geographically diverse metropolitan areas in the United States on a quarterly basis from 2004 to 2011. Generalized estimating equations assessed whether implementation of a prescriber-accessible PDMP was associated with a difference in ED visits involving opioid analgesics. Models were adjusted for calendar quarter, metropolitan area, metropolitan area-specific linear time trends, and unemployment rate.ResultsRates of ED visits involving opioid analgesics increased in all metropolitan areas. PDMP implementation was not associated with a difference in ED visits involving opioid analgesics (mean difference of 0.8 visits [95% CI: -3.7 to 5.2] per 100,000 residents per quarter).ConclusionsDuring 2004-2011, PDMP implementation was not associated with a change in opioid-related morbidity, as measured by emergency department visits involving opioid analgesics. Urgent investigation is needed to determine the optimal PDMP structure and capabilities to improve opioid analgesic safety.
Project description:INTRODUCTION:Hookah (also known as waterpipe) smoking is associated with acute adverse health effects such as vomiting and fainting, symptoms related to carbon monoxide poisoning, and decreased pulmonary function, however, national estimates of hookah-related acute injuries are not currently available in the scientific literature. This study provides national estimates of United States hospital emergency department visits due to hookah-related acute injuries. METHODS:We analyzed 2011-2019 data from the National Electronic Injury Surveillance System to calculate national estimates of emergency department visits due to hookah-related acute injuries. National Electronic Injury Surveillance System data were gathered from approximately 100 United States hospitals selected as a probability sample of approximately 5000 hospitals with emergency departments. Each case contains information abstracted from all emergency department records involving injuries associated with consumer products. All individuals admitted to emergency departments who sustained hookah-related acute injuries were included in the study. RESULTS:During 2011-2019, an estimated 1371 (95% confidence interval: 505-2283) United States hospital emergency department visits were related to hookah-related acute injuries. The most common injuries were sustained from dizziness/light-headedness and syncopal episodes (54.8%), followed by burns (41.5%). Young adults aged 18-24?years accounted for 66.8% of hookah-related acute injuries admitted to United States emergency departments. CONCLUSIONS:This study provides national estimates of hospital emergency department visits due to hookah-related acute injuries. We found that hookah smoking related AIs mostly occurred among young adults. Study findings may inform public health policy and educational intervention efforts to prevent these events and complement other acute injury surveillance systems, such as the National Poison Data System.
Project description:ImportanceThere is a lack of literature describing the incidence of pediatric acute ocular injury and associated likelihood of vision loss in the United States. Understanding national pediatric eye injury trends may inform future efforts to prevent ocular trauma.ObjectiveTo characterize pediatric acute ocular injury in the United States using data from a stratified, national sample of emergency department (ED) visits.Design, setting, and participantsA retrospective cohort study was conducted. Study participants received care at EDs included in the 2006 to 2014 Nationwide Emergency Department Sample, comprising 376 040 children aged 0 to 17 years with acute traumatic ocular injuries. Data were analyzed from June 2016 to March 2018.ExposuresInternational Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes and external-cause-of-injury codes identified children with acute ocular injuries.Main outcomes and measuresDemographic and clinical characteristics of children with acute traumatic ocular injuries were collected and temporal trends in the incidence of ocular injuries by age, risk of vision loss, and mechanism of injury were explored.ResultsIn 2014, there were an estimated 163 431 (95% CI, 151 235-175 627) ED visits for pediatric acute ocular injury. Injured children were more often male (63.0%; 95% CI, 62.5-63.5) and in the youngest age category (birth to 4 years, 35.3%; 95% CI, 34.4-36.2; vs 10-14 years, 20.6%; 95% CI, 20.1-21.1). Injuries commonly resulted from a strike to the eye (22.5%; 95% CI, 21.3-23.8) and affected the adnexa (43.7%; 95% CI, 42.7-44.8). Most injuries had a low risk for vision loss (84.2%; 95% CI, 83.5-85.0), with only 1.3% (95% CI, 1.1-1.5) of injuries being high risk. Between 2006 and 2014, pediatric acute ocular injuries decreased by 26.1% (95% CI, -27.0 to -25.0). This decline existed across all patient demographic characteristics, injury patterns, and vision loss categories and for most mechanisms of injury. There were increases during the study in injuries related to sports (12.8%; 95% CI, 5.4-20.2) and household/domestic activities (20.7%; 95% CI, 16.2-25.2). The greatest decrease in high-risk injuries occurred with motor vehicle crashes (-79.8%; 95% CI, -85.8 to -74.9) and guns (-68.5%; 95% CI, -73.5 to -63.6).Conclusions and relevanceThis study demonstrated a decline in pediatric acute ocular injuries in the United States between 2006 and 2014. However, pediatric acute ocular injuries continue to be prevalent, and understanding these trends can help establish future prevention strategies.
Project description:ObjectiveTo understand the prevalence of child maltreatment-related emergency department (ED) visits in the United States, we examined data from the 2007 to 2014 Nationwide Emergency Department Sample.MethodsBased on existing literature, International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9 CM) ED discharge codes for children less than 10 years of age were characterized as specified child maltreatment, defined as visits with an explicit maltreatment ICD-9 CM or external causes of injury codes. The prevalence of child maltreatment visits per 100,000 children in the United States (based on Center for Disease Control Wide-ranging ONline Data for Epidemiologic Research estimates) overall and by sociodemographic factors was examined, and tests for trends over time were evaluated with Cochran-Armitage tests. Analyses were conducted in 2019.ResultsThe prevalence of child maltreatment based in ICD-9 CM discharge codes ED visits dropped from 69.2 visits per 100,000 in 2007 to 65.9 visits per 100,000 in 2014; this trend was statistically significant. The prevalence was lowest in 2010 (60.1 visits per 100,000 children). There were increases observed for some demographic groups in this period. Throughout the 8-year period examined, the prevalence of child maltreatment visits was highest for physical abuse compared with other forms of maltreatment, higher for boys compared with girls; highest for children younger than 1 year, and higher for children living in neighborhoods with the lowest median income compared with children in higher-income neighborhoods.ConclusionsThe Nationwide Emergency Department Sample data set is a valuable surveillance tool for examining trends in child maltreatment. Future studies should explore what factors may explain variations in child maltreatment over time to best develop prevention strategies.
Project description:BackgroundAntibiotics are among the most commonly prescribed medications for children; however, at least one-third of pediatric antibiotic prescriptions are unnecessary. National data on short-term antibiotic-related harms could inform efforts to reduce overprescribing and to supplement interventions that focus on the long-term benefits of reducing antibiotic resistance.MethodsFrequencies and rates of emergency department (ED) visits for antibiotic adverse drug events (ADEs) in children were estimated using adverse event data from the National Electronic Injury Surveillance System-Cooperative Adverse Drug Event Surveillance project and retail pharmacy dispensing data from QuintilesIMS (2011-2015).ResultsOn the basis of 6542 surveillance cases, an estimated 69464 ED visits (95% confidence interval, 53488-85441) were made annually for antibiotic ADEs among children aged ≤19 years from 2011 to 2015, which accounts for 46.2% of ED visits for ADEs that results from systemic medication. Two-fifths (40.7%) of ED visits for antibiotic ADEs involved a child aged ≤2 years, and 86.1% involved an allergic reaction. Amoxicillin was the most commonly implicated antibiotic among children aged ≤9 years. When we accounted for dispensed prescriptions, the rates of ED visits for antibiotic ADEs declined with increasing age for all antibiotics except sulfamethoxazole-trimethoprim. Amoxicillin had the highest rate of ED visits for antibiotic ADEs among children aged ≤2 years, whereas sulfamethoxazole-trimethoprim resulted in the highest rate among children aged 10 to 19 years (29.9 and 24.2 ED visits per 10000 dispensed prescriptions, respectively).ConclusionsAntibiotic ADEs lead to many ED visits, particularly among young children. Communicating the risks of antibiotic ADEs could help reduce unnecessary prescribing. Prevention efforts could target pediatric patients who are at the greatest risk of harm.
