Type II odontoid fractures in the elderly presenting to the emergency department: an assessment of factors affecting in-hospital mortality and discharge to skilled nursing facilities

BACKGROUND CONTEXT

Type II odontoid fractures (OF) are among the most common cervical spine injuries in the geriatric population. However, there is a paucity of literature regarding their epidemiology. Additionally, the optimal management of these injuries remains controversial, and no study has evaluated the short-term outcomes of geriatric patients presenting to emergency departments (ED).

PURPOSE

This study aims to document the epidemiology of geriatric patients presenting to EDs with type II OFs and determine whether surgical management was associated with early adverse outcomes such as in-hospital mortality and discharge to skilled nursing facilities (SNF).

STUDY DESIGN

This is a retrospective cohort study.

PATIENT SAMPLE

Data was used from the 2016-2020 Nationwide Emergency Department Sample. Patient encounters corresponding to type II OFs were identified. Patients younger than 65 at the time of presentation to the ED and those with concomitant spinal pathology were excluded.

OUTCOME MEASURES

The association between the surgical management of geriatric type II OFs and outcomes such as in-hospital mortality and discharge to SNFs.

METHODS

Patient, fracture, and surgical management characteristics were recorded. A propensity score matched cohort was constructed to reduce differences in age, comorbidities, and injury severity between patients undergoing operative and nonoperative management. Additionally, to develop a positive control for the analysis of geriatric patients with type II OFs and no other concomitant spinal pathology, a cohort of patients that had been excluded due to the presence of a concomitant spinal cord injury (SCI) was also constructed. Multivariate regressions were then performed on both the matched and unmatched cohorts to ascertain the associations between surgical treatment and in-hospital mortality, inpatient length of stay, encounter charges, and discharge to SNFs.

RESULTS

A total of 11,325 encounters were included. The mean total charge per encounter was $60,221. 634 (5.6%) patients passed away during their encounters. In total, 1,005 (8.9%) patients were managed surgically. Surgical management of type II OFs was associated with a 316% increase in visit charge (95% CI: 291%-341%, p<.001), increased inpatient length of stay (IRR: 2.87, 95% CI: 2.62-3.12, p<.001), and increased likelihood of discharge to SNFs (OR=2.62, 95% CI: 2.26-3.05, p<.001), but decreased in-hospital mortality (OR=0.32, CI: 0.21-0.45, p<.001). The propensity score matched cohort consisted of 2,010 patients, matching each of the 1,005 that underwent surgery to 1,005 that did not. These cohorts were well balanced across age (78.24 vs 77.91 years), Elixhauser Comorbidity Index (3.68 vs 3.71), and Injury Severity Score (30.15 vs 28.93). This matching did not meaningfully alter the associations determined between surgical management and in-hospital mortality (OR=0.34, CI=0.21-0.55, p<.001) or SNF discharge (OR=2.59, CI=2.13-3.16, p<.001). Lastly, the positive control cohort of patients with concurrent SCI had higher rates of SNF discharge (50.0% vs 42.6%, p<.001), surgical management (32.3% vs 9.7%, p<.001), and in-hospital mortality (28.9% vs 5.6%, p<.001).

CONCLUSIONS

This study lends insight into the epidemiology of geriatric type II OFs and quantifies risk factors influencing adverse outcomes. Patient informed consent should include a discussion of the protective association between definitive surgical management and in-hospital mortality against potential operative morbidity, increased lengths of hospital stay, and increased likelihood of discharge to SNFs. This information may impact patient treatment selection and decision making.

Emergency services utilization by patients with alcohol-associated hepatitis: An analysis of national trends

BACKGROUND

Hospitalization and mortality in patients with alcohol-associated hepatitis (AH), a severe form of liver disease, continue to increase over time. Given the severity of the illness, most hospitalized patients with AH are admitted from the emergency department (ED). However, there are no data on ED utilization by patients with AH. Thus, the Nationwide Emergency Department Sample (NEDS) dataset was analyzed to determine the ED utilization for AH.

METHODS

Temporal trends (2016-2019) and outcomes of ED visits for AH were determined. Primary or secondary AH diagnoses were based on coding priority. Numbers of patients evaluated in the ED, severity of disease, complications of liver disease, and discharge disposition were analyzed. Crude and adjusted rates were examined, and temporal trends evaluated using logistic regression with orthogonal polynomial contrasts for each year.

RESULTS

There were 466,014,370 ED visits during 2016-2019, of which 448,984 (0.096%) were for AH, 85.0% of which required hospitalization. The rate of visits for AH (primary and secondary) between 2016 and 2019 increased from 85 to 106.8/100,000 ED visits. The rate of secondary AH increased more than the rate of primary AH (from 68.6 to 86.5 vs. from 16.4 to 20.3/100,000 ED visits). Patients aged 45-64 years had the highest rate of ED visits for AH, which decreased during the study period, while the rate of ED visits for AH increased in those aged 25-44 years (from 38.5% to 42.9%). The severity of disease (ascites, hepatic encephalopathy, and acute kidney injury) also increased over time. Medicaid and private insurance were the most common payors for patients seeking care in the ED for AH.

CONCLUSIONS

Temporal trends show an overall increase in ED utilization rates for AH, more patients requiring hospitalization, and an increase in the proportion of younger patients presenting to the ED with AH.

Epidemiology of pelvic and acetabular fractures in the USA from 2007 to 2014

Incidence of pelvic and acetabular fracture is increasing in Europe. From 2007 to 2014 in the USA, this study found an age-adjusted incidence of 198 and 40 fractures/100,000/year, respectively, much higher than what has been described before. Incidence remained steady over that period and only a small increase in incidence of pelvic fracture in men was identified.

PURPOSE

To determine the incidence of pelvic ring and acetabular fractures in the USA over the period 2007-2014 and to examine trends over time.

METHODS

Retrospective population-based observational study using data from the Nationwide Emergency Department Sample (NEDS), a 20% stratified all-payer sample of US hospital-based emergency departments (EDs). All patients seen in the ED and diagnosed with pelvic/acetabular fracture from 2007 to 2014 were included. The primary outcome was age-adjusted incidence of pelvic and acetabular fractures per 100,000 persons/years. Secondary outcomes included incidence stratified by age and sex, patient- and hospital-related characteristics, and ED procedures. Tests for linear trends were used to determine if there were statistically significant differences by sex and age groups over time.

RESULTS

The age-adjusted incidence of pelvic fracture was 198 fractures/100,000/year, 323 in women and 114 in men. The age-adjusted incidence of acetabular fracture was 40 fractures/100,000/year, 36 in women and 51 in men. A small increase in the age-adjusted incidence of pelvic fracture in men was the only significant trend observed during the study time (p = 0.03). Over that period, the mean age of patients at presentation increased, as well as their number of comorbidities and associated fragility fractures, and they were more often sent home or to nursing facilities.

CONCLUSIONS

When considering all patients coming to the ED, not only those admitted to the hospital, adjusted incidence of pelvic and acetabular fracture is much higher than what has been described before. Contrarily to the global increase seen in other countries, incidence of pelvic and acetabular fractures dropped in the USA from 2007 to 2014 and only a small increase in age-adjusted incidence of pelvic fracture in men was identified.

Emergency department burden of hyperemesis gravidarum in the United States from 2006 to 2014

BACKGROUND

Hyperemesis gravidarum is the most severe form of nausea and vomiting of pregnancy, potentially affecting both maternal and pregnancy health. Hyperemesis gravidarum often results in emergency department visits, although the exact frequency and costs associated with these visits have not been well studied.

OBJECTIVE

This study aimed to analyze the trends in hyperemesis gravidarum emergency department visits, inpatient admissions, and the associated costs between 2006 and 2014.

STUDY DESIGN

Patients were identified from the 2006 and 2014 Nationwide Emergency Department Sample database files using International Classification of Diseases, Ninth Revision diagnosis codes. Patients with a primary diagnosis of hyperemesis gravidarum, nausea and vomiting of pregnancy, and all nondelivery pregnancy-related diagnoses (all antepartum visits) were identified. All groups were analyzed; trends in demographics, number of emergency department visits, and visit costs were compared. Costs were inflation-adjusted to 2021 US dollars.

RESULTS

Emergency department visits for hyperemesis gravidarum increased by 28% from 2006 to 2014; however, the proportion of those who were subsequently admitted to the hospital decreased. The average cost of an emergency department visit for hyperemesis gravidarum increased by 65% ($2156 to $3549), as opposed to an increase of 60% for all antepartum visits ($2218 to $3543). The aggregate cost for all hyperemesis gravidarum visits increased by 110% ($383,681,346 to $806,696,513) from 2006 to 2014, which was similar to the increase observed for all antepartum emergency department visits.

CONCLUSION

From 2006 to 2014, emergency department visits for hyperemesis gravidarum increased by 28%, with associated costs increasing by 110%, whereas the number of admissions from the emergency department for hyperemesis gravidarum decreased by 42%.

Childhood adversity, suicidality, and non-suicidal self-injury among children and adolescents admitted to emergency departments

PURPOSE

This population-based study explored the associations between childhood adversity and admission to emergency departments (EDs) with non-suicidal self-injury (NSSI) and with a suicide attempt.

METHODS

A nationally representative cross-sectional sample of 5-17-year-olds admitted to EDs (N = 143,113,677) from 2006 to 2015 was utilized to assess the associations between childhood adversities, NSSIs, and suicide attempts.

RESULTS

ED admissions with NSSI and admissions with a suicide attempt were associated with greater odds of exposure to individual childhood adversities (aORs: 1.34 to 5.86; aORs: 2.37 to 15.69, respectively). ED admissions with a suicide attempt were associated with greater odds of exposure to childhood adversities that might be perceived as less extreme or harmful (separation or divorce aOR: 15.69) than other adversities (death of a family member aOR: 13.38; history of physical abuse aOR: 9.56) as well as greater odds of exposure to three or more childhood adversities (aOR: 20.98).

CONCLUSION

Early detection of childhood adversities is important for identifying potential risk factors for self-harm. ED admission data can provide population-level surveillance to aid in these efforts and lead to more targeted and effective interventions aimed at reducing the negative effects of toxic stress that can result from exposure to childhood adversities.

Treated-and-released urinary catheterization in the emergency department by sex

BACKGROUND

The prevalence and difference in likely indications of urinary catheterization (UC) in treated-and-released emergency department (ED) visits between men and women are currently unknown.

METHODS

This was a cross-sectional analysis using the 2013 National Emergency Department Sample for all treated-and-released visits in persons aged ≥18 years. The prevalence of conditions associated with UC visits in men and women were identified. A hierarchical ranking was used to categorize diagnosis codes identified during ED visits into clinically meaningful categories to assess conditions for UC.

RESULTS

In 2013, there were 87,797,062 treated-and-released ED visits in adults. The rate of UC in treated-and-released ED visits in adults was 4.3 per 1,000 visits, with 6.5 per 1,000 visits in men and 2.7 per 1,000 visits in women. Using the hierarchal ranking, a higher proportion of UC visits in men were coded for acute urinary retention, and a higher proportion of UC visits in women were coded for neurologic, cognitive, and psychiatric conditions.

CONCLUSIONS

The rate of UC in treated-and-released ED visits was higher in men than women, and UC rate increased with age. The heterogeneity of conditions coded in UC visits in women compared with men may suggest more potentially avoidable UC in women in the treated-and-released ED population. If confirmed, this would suggest opportunities for quality improvement in the ED to prevent overutilization of urinary catheters.

Incidence and Cost of Ankle Sprains in United States Emergency Departments

BACKGROUND

Ankle sprains represent a common injury in emergency departments, but little is known about common complications, procedures, and charges associated with ankle sprains in emergency departments.

HYPOTHESIS

There will be a higher incidence of ankle sprains among younger populations (≤25 years old) and in female patients. Complications and procedures will differ between ankle sprain types. Lateral ankle sprains will have lower health care charges relative to medial and high ankle sprains.

STUDY DESIGN

Descriptive epidemiological study.

LEVEL OF EVIDENCE

Level 3.

METHODS

A cross-sectional study of the 2010 Nationwide Emergency Department Sample was conducted. Outcomes such as charges, complications, and procedures were compared using propensity score matching between lateral and medial as well as lateral and high ankle sprains.

RESULTS

The sample contained 225,114 ankle sprains. Female patients sustained more lateral ankle sprains (57%). After propensity score adjustment, lateral sprains incurred greater charges than medial ankle sprains (median [interquartile range], $1008 [$702-$1408] vs $914 [$741-$1108]; P < 0.01). Among complications, pain in the limb (1.92% vs 0.52%, P = 0.03), sprain of the foot (2.96% vs 0.70%, P < 0.01), and abrasion of the hip/leg (1.57% vs 0.35%, P = 0.03) were more common in lateral than medial ankle sprain events. Among procedures, medial ankle sprains were more likely to include diagnostic radiology (97.91% vs 83.62%, P < 0.01) and less likely to include medications than lateral ankle sprains (0.87% vs 2.79%, P < 0.01). Hospitalizations were more common following high ankle sprains than lateral ankle sprains (24 [6.06%] vs 1 [0.25%], P < 0.01).

CONCLUSION

Ankle sprain emergency department visits account for significant health care charges in the United States. Age- and sex-related differences persist among the types of ankle sprains.

CLINICAL RELEVANCE

The health care charges associated with ankle sprains indicate the need for additional preventive measures. There are age- and sex-related differences in the prevalence of ankle sprains that suggest these demographics may be risk factors for ankle sprains.

Traumatic Spinal Cord Injury Emergency Service Triage Patterns and the Associated Emergency Department Outcomes

Paralysis is an indication for trauma patients to be preferentially triaged by emergency services to designated level I or II trauma centers (TC). We sought to describe triage practices for patients with acute traumatic spinal cord injury (TSCI) and its associated emergency department (ED) outcomes. Adults ages ≥ 18 years with a diagnosis of acute TSCI (International Classification of Diseases-9: 806 and 952) in the 2006-2011 United States Nationwide Emergency Department Sample were included in these analyses. Outcomes assessed include triage to non-trauma centers (NTC), which is referred to as "under-triage," and ED mortality. Of 117,444 adults with TSCI, 33.4% were under-triaged to NTC. Under-triage was more prevalent with increasing age. Among patients under-triaged to NTC, 37.4% had new injury severity score (NISS) >15, representing severe injuries or polytrauma. Among patients with NISS >15, the odds of ED mortality in NTC were four-fold greater compared to level I trauma centers (TC-I) (adjusted odds ratio [AOR] = 4.06; 95% confidence interval = 1.87-8.79; p < 0.001). In conclusion, under-triage of adults with acute TSCI occurred in at least one-third of the cases. Patients triaged to NTC rather than TC-I experienced higher likelihood of death in the ED even after controlling for personal and injury characteristics. Further research is necessary to elucidate detailed clinical and logistical factors that may be associated with under-triage of acute TSCI, to facilitate interventions aimed at improving patient experience and outcomes.

Undertriage of older trauma patients: is this a national phenomenon?

BACKGROUND

Older age is associated with high rates of morbidity and mortality after injury. Statewide studies suggest significantly injured patients aged ≥55 y are commonly undertriaged to lower level trauma centers (TCs) or nontrauma centers (NTCs). This study determines whether undertriage is a national phenomenon.

MATERIALS AND METHODS

Using the 2011 Nationwide Emergency Department Sample, significantly injured patients aged ≥55 y were identified by diagnosis and new injury severity score (NISS) ≥9. Undertriage was defined as definitive care anywhere other than level I or II TCs. Weighted descriptive analysis compared characteristics of patients by triage status. Multivariable logistic regression determined predictors of undertriage, controlling for hospital characteristics, injury severity, and comorbidities.

RESULTS

Of 4,152,541 emergency department (ED) visits meeting inclusion criteria, 74.0% were treated at lower level TCs or NTCs. Patients at level I and II TCs more commonly had NISS ≥9 (22.2% versus 12.3%, P < 0.001), but among all patients with NISS ≥9, 61.3% were undertriaged to a lower level TC or a NTC. On multivariable logistic regression, factors independently associated with higher odds of being undertriaged were increasing age, female gender, and fall-related injuries. A subgroup analysis examined urban and suburban areas only where access to a TC is more likely and found that 55.8% of patients' age were undertriaged.

CONCLUSIONS

There is substantial undertriage of patients aged ≥55 y nationwide. Over half of significantly injured older patients are not treated at level I or II TCs. The impact of undertriage should be determined to ensure older patients receive trauma care at the optimal site.

United States emergency department visits coded for intimate partner violence

BACKGROUND

Limited information exists about medical treatment for victims of intimate partner violence (IPV).

OBJECTIVE

Our aim was to estimate the number of emergency department (ED) visits and subsequent hospitalizations that were assigned a code specific to IPV and to describe the clinical and sociodemographic features of this population.

METHODS

Data from the Nationwide Emergency Department Sample from 2006-2009 were analyzed. Cases with an external cause of injury code of E967.3 (battering by spouse or partner) were abstracted.

RESULTS

From 2006-2009, there were 112,664 visits made to United States EDs with an e-code for battering by a partner or spouse. Most patients were female (93%) with a mean age of 35 years. Patients were significantly more likely to reside in communities with the lowest median income quartile and in the Southern United States. Approximately 5% of visits resulted in hospital admission. The mean charge for treat-and-release visits was $1904.69 and $27,068.00 for hospitalizations. Common diagnoses included superficial injuries and contusions, skull/face fractures, and complications of pregnancy. Females were more likely to experience superficial injuries and contusions, and males were more likely to have open wounds of the head, neck, trunk, and extremities.

CONCLUSIONS

From 2006 to 2009, there were approximately 28,000 ED visits per year with an e-code specific to IPV. Although a minority, 7% of these visits were made by males, which has not been reported previously. Future prospective research should confirm the unique demographic and geographic features of these visits to guide development of targeted screening and intervention strategies to mitigate IPV and further characterize male IPV visits.

Incidence and treatment patterns in males presenting with lower urinary tract symptoms to the emergency department in the United States

PURPOSE

Due to varying clinical definitions of lower urinary tract symptoms, it has been difficult to determine comparable prevalence and incidence rates of lower urinary tract symptoms and their treatment modalities. We assessed the incidence of emergency department visits in men with lower urinary tract symptoms who presented to emergency departments in the United States and factors associated with an increased likelihood of hospitalization.

MATERIALS AND METHODS

Emergency department visits from 2006 to 2009 associated with a primary diagnosis of lower urinary tract symptoms using established criteria were abstracted from the Nationwide Emergency Department Sample. Age adjusted incidence rates of emergency department visits and charges were calculated. We performed multivariable analysis to examine patient and hospital characteristics of those hospitalized and those with benign prostatic hyperplasia related adverse events.

RESULTS

A weighted estimate of 1,178,423 emergency department visits for lower urinary tract symptoms was recorded with a national incidence of 197.6/100,000 males per year. A total of 112,288 visits (9.5%) resulted in hospitalization. Adverse events were identified in 734,269 patients (62.3%). The most common adverse events were catheterization in 44.6% of cases, infection in 17.4%, hematuria in 9.6%, bladder stones in 1.7%, hydronephrosis in 1.2% and acute renal failure in 0.1%. On multivariable analysis independent predictors of hospital admission included comorbidities, socioeconomic status, hospital characteristics and adverse events such as sepsis, acute renal failure and hydronephrosis. Independent predictors of adverse events included patient age, year of visit, socioeconomic status, hospital characteristics and concomitant neurological disease. In 2009 total emergency department charges for lower urinary tract symptoms were $494,981,922.

CONCLUSIONS

The number of men with lower urinary tract symptoms who visit the emergency department has remained stable, while emergency department charges have increased by 40%. The rate of adverse events increased during the study period. These findings might suggest over reliance on medical and conservative therapy in the contemporary era.
