Emergency department reliance: a discriminatory measure of frequent emergency department users

Opioid Use Among Children and Adults With Sickle Cell Disease in North Carolina Medicaid Enrollees in the Era of Opioid Harm Reduction

Adults and children with sickle cell disease (SCD) are predominantly African American, with pain-related health disparities. We examined opioid prescription fill patterns in adults and children with SCD and compared factors associated with fills in North Carolina Medicaid enrollees. Our retrospective cohort study included 955 enrollees diagnosed with SCD having at least one opioid fill. Associations were measured between two cohorts (12 and 24 mo of continuous enrollment) for the following characteristics: sex, age, enrollee residence, hydroxyurea adherence, comanagement, enrollment in Community Care North Carolina, prescription for short versus short and long-acting opioids, and emergency department reliance. The majority of individuals did not have an opioid claim over a 12 or 24-month period. Claims increased at ages 10 to 17, peaking at ages 18 to 30. The increased number of claims was associated with the following factors: increasing age, male, short versus long-acting opioids, and Medicaid enrollment for 24 versus 12 months. Community Care North Carolina enrollees in the 12-month cohort had higher opioid days of supply per month; the inverse was true of the 24-month cohort.

The effects of a large-scale home visiting programme for child development on use of health services in Brazil

Partnership between early childhood development interventions and primary health care services can help catalyse health care uptake by socially vulnerable families. This study aimed to assess the real-life effects of a large-scale home visiting programme [Primeira Infância Melhor (PIM)] in Brazil on the use of preventive (prenatal visits, well child visits, dentist visits and vaccination) and recovery (emergency room visits and hospitalization) health services. A quasi-experiment nested in a population-based birth cohort study was conducted. The intervention group was firstly defined as all children enrolled in PIM up to age 6 months, and afterwards stratified between those enrolled during pregnancy or after birth up to 6 months. Children receiving PIM were matched with controls on propensity scores based on 27 confounders to estimate effects on health service use from prenatal to age 2 years. Double adjustment was applied in outcome Quasi-Poisson regressions. No evidence was found for effects of PIM starting anytime up to 6 months (262 pairs), or for the children enrolled only after birth (133 pairs), on outcomes occurring after age 6 months. When the programme started during pregnancy (129 pairs), there was a 13% higher prevalence of adequate prenatal visits (prevalence ratio = 1.13; 95% confidence interval 1.01-1.27), but no effect on use of any other health service. Sensitivity analyses suggested longer participation in the programme with reduced visitor turnover might improve its impact on prenatal visits. Integration between PIM and primary health care was not adequate to affect overall patterns of contacts with health services. Nevertheless, prenatal home visits showed potential to increase health service contact during a sensitive period of development, indicating the need to start such programmes before birth, when there is more time for maternal care, and family engagement in a network of services is facilitated.

Epidemiology of pediatric trauma and fractures during and beyond the COVID-19 pandemic

Purpose

Previous literature has shown decreases in pediatric trauma during the COVID-19 outbreak, but few have analyzed beyond the peak of the pandemic. This study assesses the epidemiology of pediatric trauma cases in a high-volume teaching hospital in New York City before, during, and after the height of the COVID-19 pandemic.

Methods

Institutional data on pediatric trauma orthopedic cases from January 1, 2018 to November 30, 2021 were extracted. The following time frames were studied: (1) April 1-June 22 in 2018 and 2019 (pre-pandemic), (2) April 1-June 22, 2020 (peak pandemic), and (3) April 1-June 22, 2021 (post-peak pandemic). Inferential statistics were used to compare patient and trauma characteristics.

Results

Compared to the pre-pandemic cohort (n = 6770), the peak pandemic cohort (n = 828) had a greater proportion of fractures (p < 0.01) and had a significantly decreased overall traumas per week rate (p < 0.01) and fractures per week rate (p < 0.01). These decreased trauma (p < 0.01) and fracture rates (p < 0.01) persisted for the post-peak pandemic cohort (n = 2509). Spatial analysis identified zip code clusters throughout New York City with higher rates of emergency department presentation during the peak pandemic compared to pre-pandemic, and these areas aligned with lower-income neighborhoods.

Conclusion

During the peak of the pandemic, overall trauma and fracture volumes decreased, the types of prevalent injuries changed, and neighborhoods of different economic resources were variably impacted. These trends have mostly persisted for 12 months post-peak pandemic. This longitudinal analysis helps inform and improve long-term critical care and public health resource allocation for the future.

Cardiovascular health trajectories from age 2-12: a pediatric electronic health record study

PURPOSE

Many children have non-ideal cardiovascular health (CVH), but little is known about the course of CVH in early childhood. We identified CVH trajectories in children and assess the generalizability of these trajectories in an external sample.

METHODS

We used data spanning 2010-2018 from children aged 2-12 years within the Chicago Area Patient-Centered Outcomes Research Network-an electronic health record network. Four clinical systems comprised the derivation sample and a fifth the validation sample. Body mass index, blood pressure, cholesterol, and blood glucose were categorized as ideal, intermediate, and poor using clinical measurements, laboratory readings, and International Classification of Diseases diagnosis codes and summed for an overall CVH score. Group-based trajectory modeling was used to create CVH score trajectories which were assessed for classification accuracy in the validation sample.

RESULTS

Using data from 122,363 children (47% female, 47% non-Hispanic White) three trajectories were identified: 59.5% maintained high levels of clinical CVH, 23.4% had high levels of CVH that declined, and 17.1% had intermediate levels of CVH that further declined with age. A similar classification emerged when the trajectories were fitted in the validation sample.

CONCLUSIONS

Stratification of CVH was present by age 2, implicating the need for early life and preconception prevention strategies.

Describing the Patient Population of a Pediatric Emergency Department Based on Visit Frequency

OBJECTIVE

A small number of children in the United States use a disproportionate share of emergency healthcare services. Our study objective was to examine characteristics associated with frequent pediatric emergency department (PED) utilization.

METHODS

A retrospective cohort-sequential study of patients seen in the PED of an urban children's hospital was conducted. Patients were categorized into 2 groups: infrequent users (<4 visits during index year 2017) and frequent users (≥4 visits in 2017). Frequent PED users were further divided into persistent frequent (≥4 visits in the year before and after 2017) and incidental frequent (≥4 visits in 2017). Patient- and visit-level characteristics were analyzed for associations with PED utilization.

RESULTS

In 2017, there were 82,361 visits by 56,767 patients to our PED. Frequent users comprised 4% of the total patient volume but accounted for 13% of visits. Compared with infrequent users, frequent users were younger, more likely publicly insured, and English speaking. Frequent user visits were more likely to occur outside clinic hours, be triaged as emergent, and involve subspecialists. Compared with visits by incidental frequent users, visits by persistent frequent users were more likely to be emergent or urgent, and involve subspecialists, diagnostic imaging, laboratory testing, and medication administration.

CONCLUSIONS

Although the percentage of frequent users to a PED in 2017 was low, they made up a disproportionate share of total visits. Differences between persistent and incidental frequent PED users suggest that these subgroups may benefit from tailored interventions to reduce frequent PED utilization.

Relationship Between Food Insecurity and Neighborhood Child Opportunity Index

OBJECTIVES

To evaluate the association between the Child Opportunity Index (COI) and food insecurity.

STUDY DESIGN

This was a secondary analysis of a comprehensive screening instrument for social determinants of health and behavioral health risks. It was administered in 2 urban pediatric emergency departments to adolescents aged 13-21 years and caregivers of children aged 0-17 years. Food insecurity was assessed using the 2-item Hunger Vital Sign. Residential addresses were geocoded and linked with COI data. Bivariable and multivariable logistic regression models were developed to measure the relationship between COI and food insecurity.

RESULTS

Of the 954 participants (384 adolescents, 570 caregivers) who underwent screening, 15.7% identified food insecurity (14.3% of adolescent and 16.7% of caregiver participants). The majority of participants were non-Hispanic Black (overall, 62.3%; food secure, 60.9%; food insecure, 72.0%), were publicly insured (overall, 56.6%; food secure, 53.1%; food insecure, 73.3%), and lived in neighborhoods of low/very low opportunity (overall, 76.9%; food secure, 74.7%; food insecure, 88.3%). In adjusted analyses, participants living in neighborhoods of low/very low child opportunity had 3-fold greater odds of being food insecure compared with children living in neighborhoods of high child opportunity (aOR, 3.0; 95% CI, 1.4-6.3).

CONCLUSION

We demonstrate that food insecurity is associated with lower neighborhood opportunity. Our results could inform future screening initiatives and support the development of novel, place-based interventions to tackle the complex issue of food insecurity.

Measuring transition readiness in adolescents and young adults with sickle cell disease using the transition readiness assessment questionnaire

BACKGROUND/OBJECTIVES

Adolescents and young adults (AYA) with sickle cell disease (SCD) face challenges related to the disease and its treatment. The Transition Readiness Assessment Questionnaire (TRAQ) is a self-report tool for assessing transition readiness for youth with special health care needs (YSHCN), including SCD. This study uses the TRAQ to understand transition readiness in patients with SCD treated at the Boston Medical Center and evaluates associations between TRAQ scores and transition outcomes (e.g., emergency department reliance [EDr] and emergency department utilization [EDu]).

METHODS

We reviewed electronic medical records of AYA with SCD who completed the TRAQ in the pediatric hematology clinic between January 1, 2019, and March 1, 2020, and categorized healthcare encounters to calculate EDu and EDr.  We used t tests and ANOVA models to analyze mean TRAQ scores, sex, age, genotype, EDu, and EDr.

RESULTS

The sample was 45 AYA patients with SCD between 13 and 22 years old. The mean TRAQ score for the overall patient sample was 3.67. Mean TRAQ scores did not significantly vary by sex or genotype but did significantly increase with age. TRAQ scores did not correlate to EDu or EDr.

CONCLUSIONS

AYA patients with SCD have low transition readiness. The age of 18 may not be the most reliable attribute of readiness, though older patients do have higher readiness. The relationship between TRAQ scores, EDr, and EDu is not clear and requires further evaluation.

Frequent Emergency Department Use by Children

OBJECTIVES

Frequent use of the emergency department (ED) is often targeted as a quality improvement metric. The objective of this study was to assess ED visit frequency by the demographic and health characteristics of children who visit the ED to better understand risk factors for high ED utilization.

METHODS

The majority of pediatric ED services in Rhode Island are provided by a hospital network that includes the state's only children's hospital. Using 10 years of data (2005-2014) from this statewide hospital network, we examined ED use in this network for all children aged 0 to 17 years. Patients' home addresses were geocoded to assess their neighborhood characteristics.

RESULTS

Between 2005 and 2014, 17,844 children visited 1 or more of the network EDs at least once. In their year of maximum use, 67.8% had only 1 ED visit, 20.1% had 2 visits, 6.9% had 3 visits, and 5.2% had 4 or more visits. In the adjusted multinomial logistic regression model, age, race/ethnicity, language, insurance coverage, medical complexity, neighborhood risk, and distance to the ED were found to be significantly associated with increased visit frequency.

CONCLUSIONS

Risk factors for frequent ED use by children include age, race/ethnicity, language, insurance coverage, medical complexity, neighborhood risk, and distance to the hospital. To decrease frequent pediatric ED use, improved medical management of complex medical problems is needed, but it is also essential to address modifiable social determinants of health care utilization in this population.

Reliance on Acute Care Settings for Health Care Utilization: A Comparison of Adolescents With Younger Children

OBJECTIVE

Because a goal of the Affordable Care Act was to increase preventive care and reduce high-cost care, the objective of this study was to evaluate current health care use and reliance on acute care settings among Medicaid-enrolled children.

METHODS

This was a retrospective cohort study of the 2015 Truven Marketscan Medicaid claims database among children 0 to 21 years old with at least 11 months of continuous enrollment. We calculated adjusted probabilities of health care use (any health care use and ≥1 health maintenance visit) and high acute care reliance (ratio of emergency department or urgent care visits to all health care visits >0.33) by age and compared use between adolescents and younger children using multivariable logistic regression.

RESULTS

Of the 5,182,540 Medicaid-enrolled children, 18.9% had no health care visits and 47.3% had 1 or more health maintenance visit in 2015. Both health care use and health maintenance visits decreased with increasing age (P < 0.001). Compared with younger children (0-10 years old), adolescents were more likely to have no interaction with the health care system [adjusted odds ratio (aOR), 2.20; 95% confidence interval (CI), 2.19-2.21] and less likely to have health maintenance visits (aOR, 0.40; 0.39-0.40). High acute care reliance was associated with increasing age, with adolescents having greater odds of high acute care reliance (aOR, 1.08; 1.08-1.09).

CONCLUSIONS

Medicaid-enrolled adolescents have low rates of health care use and have high reliance on acute care settings. Further investigation into adolescent-specific barriers to health maintenance care and drivers for acute care is warranted.

Age-related healthcare services utilization for the management of sickle cell disease among treated Texas Medicaid patients

Objectives

To determine if there are age-related differences in sickle cell disease (SCD)-related healthcare utilization and to describe temporal healthcare utilization following an emergency department (ED) visit or hospitalization in treated SCD patient population.

Methods

Texas Medicaid prescription and medical claims from 1 September 2011 to 31 August 2016 were used. Patients aged 2–63 years with at least one inpatient or outpatient SCD medical claim and receiving one or more SCD-related medications (hydroxyurea, opioid or non-opioid analgesics) were included. The primary outcomes were utilization of SCD-related ED, inpatient and outpatient visits, all-cause prescription medications and type of SCD-related service at index and subsequent healthcare services. Age group was the primary independent variable.

Key findings

Overall (N = 2339), healthcare service utilization was relatively higher among age groups 2–12, 18–25 and 26–40. Proportions of patients having ≥1 ED and ≥1 inpatient visits, respectively, were significantly higher among age groups 2–12 (33.2%; 23.0%), 18–25 (29.3%; 25.1%) and 26–40 (32.3%; 22.4%) as compared with age group 13–17 (21.3%; 12.9%). The number of outpatient visits was highest among children aged 2–12 (4.5 ± 7.6, P &lt; 0.0001), while mean number of all-cause medications was the highest for older adults aged 41–63 (22.4 ± 16.3; P &lt; 0.0001). After an index ED visit (N = 598), outpatient visits were the most prevalent healthcare services. After an index hospitalization (N = 203), a subsequent hospitalization was the most prevalent healthcare service.

Conclusions

Texas Medicaid SCD patients receiving treatment have a high use of healthcare services, especially among children and young adults who are transitioning from childhood to adulthood. Age-specific interventions should be developed to promote optimal care transitions among young adults.

Neighborhood Conditions and Recurrent Emergency Department Utilization by Children in the United States

OBJECTIVE

To determine the associations of social and physical neighborhood conditions with recurrent emergency department (ED) utilization by children in the US.

STUDY DESIGN

This cross-sectional study was conducted with the National Survey of Children's Health from 2016 to 2018 to determine the associations of neighborhood characteristics of cohesion, safety, amenities, and detractors with the proportions of children aged 1-17 years with recurrent ED utilization, defined as 2 or more ED visits during the past 12 months. A multivariable regression model was used to determine the independent association of each neighborhood characteristic with recurrent ED utilization controlling for individual-level characteristics.

RESULTS

In this study of 98 711 children weighted to a population of 70 million nationally, children had significantly greater rates of recurrent ED utilization if they lived in neighborhoods that were not cohesive, were not safe, or had detractors present (all P < .001). With adjustment for individual-level covariates and the other neighborhood characteristics, only neighborhood detractors were independently associated with recurrent ED utilization (1 detractor: aOR 1.32, 95% CI 1.03-1.68; 2 or 3 detractors: aOR 1.37, 95% CI 1.04-1.81).

CONCLUSIONS

Among neighborhood characteristics, the presence of physical detractors such as rundown housing and vandalism was most strongly associated with recurrent ED utilization by children. Negative attributes of the built environment may be a potential target for neighborhood-level, place-based interventions to alleviate disparities in child healthcare utilization.

Self-reported and Documented Substance Use Among Adolescents in the Pediatric Hospital

BACKGROUND AND OBJECTIVES

Adolescent substance use is associated with numerous adverse health outcomes. A hospitalization represents an opportunity to identify and address substance use. We sought to describe self-reported and documented substance use among hospitalized adolescents.

METHODS

We conducted a cross-sectional survey of adolescents aged 14 to 18 years old admitted to two pediatric hospitals between August 2019 and March 2020. Using previously validated questions, we assessed the proportion of adolescents reporting ever, monthly, and weekly use of alcohol, marijuana, tobacco, electronic cigarettes, and other illicit drugs and nonmedical use of prescription medications. We reviewed medical records for substance use documentation.

RESULTS

Among 306 respondents, 57% were older (16-18 years old), 53% were female, and 55% were of non-Hispanic white race and ethnicity. The most frequently reported substances ever used were alcohol (39%), marijuana (33%), and electronic cigarettes (31%); 104 (34%) respondents reported ever use of >1 substance. Compared with younger adolescents, those aged 16 to 18 years were more likely to report ever use of alcohol (29% vs 46%; P = .002), marijuana (22% vs 41%; P < .001), and ≥2 drugs (26% vs 40%; P = .009). A positive substance use history was rarely documented (11% of records reviewed), and concordance between documented and self-reported substance use was also rare.

CONCLUSIONS

In this study of hospitalized adolescents, the most commonly reported substances used were alcohol, marijuana, and electronic cigarettes. Positive substance use documentation was rare and often discordant with self-reported substance use. Efforts to improve systematic screening for substance use and interventions for prevention and cessation in hospitalized adolescents are critically needed.

Frequent emergency department use in the paediatric population: A systematic literature review

OBJECTIVE

We systematically reviewed the literature on paediatric frequent emergency department (ED) users to identify and to synthesize characteristics and factors associated with frequent ED utilization among this population in the United States.

METHODS

We searched Medline (Ovid), CINAHL (Ebsco), and Embase (Ovid) to identify all relevant studies after 1990. We focused on US studies analysing paediatric frequent ED (PFED) users excluding those focused on specific subgroups. Two reviewers independently selected articles and extracted data on predisposing, enabling, behavioural, need and reinforcing factors.

RESULTS

Fifteen studies met the inclusion criteria. PFED users comprised 3% to 14% of all paediatric ED users and accounted for 9% to 42% of all paediatric ED visits in 11 studies that defined frequent use as four to six ED visits per year. Most PFED users were less than 5 years old who had public insurance coverage and a regular provider. Public insurance compared to private residency in disadvantaged areas, having at least one chronic or complex condition and a history of hospitalization, were associated with frequent use. Children who had a regular primary care provider were less likely to exhibit frequent ED use.

CONCLUSIONS

Minimizing unnecessary ED visits by frequent utilizers is a quality improvement and cost-saving priority for health systems. Our findings indicate that many PFED users have greater healthcare needs and face barriers accessing care in a timely manner, even though some have regular providers. To better address the needs of this vulnerable group, health systems should focus on educating caregivers and expanding access to providers in other settings.

Effects of variations in access to care for children with atopic dermatitis

Background

An estimated 50% of children in the US are Medicaid-insured. Some of these patients have poor health literacy and limited access to medications and specialty care. These factors affect treatment utilization for pediatric patients with atopic dermatitis (AD), the most common inflammatory skin disease in children. This study assesses and compares treatment patterns and healthcare resource utilization (HCRU) between large cohorts of Medicaid and commercially insured children with AD.

Methods

Pediatric patients with AD were identified from 2 large US healthcare claims databases (2011–2016). Included patients had continuous health plan eligibility for ≥6 months before and ≥12 months after the first AD diagnosis (index date). Patients with an autoimmune disease diagnosis within 6 months of the index date were excluded. Treatment patterns and all-cause and AD-related HCRU during the observation period were compared between commercially and Medicaid-insured children.

Results

A minority of children were evaluated by a dermatology or allergy/immunology specialist. Several significant differences were observed between commercially and Medicaid-insured children with AD. Disparities detected for Medicaid-insured children included: comparatively fewer received specialist care, emergency department and urgent care center utilization was higher, a greater proportion had asthma and non-atopic morbidities, high- potency topical corticosteroids and calcineurin inhibitors were less often prescribed, and prescriptions for antihistamines were more than three times higher, despite similar rates of comorbid asthma and allergies among antihistamine users. Treatment patterns also varied substantially across physician specialties.

Conclusions

Results suggest barriers in accessing specialty care for all children with AD and significant differences in management between commercially and Medicaid-insured children. These disparities in treatment and access to specialty care may contribute to poor AD control, especially in Medicaid-insured patients.

The relation between regular outpatient follow-up and frequency of emergency department visits in sickle cell pediatric patients

Objectives:

To evaluate the relationship between the frequency of ED visits and outpatient department (OPD) follow-up in sickle cell disease (SCD) pediatric patients.

Methods:

A retrospective cohort study included 247 SCD pediatric patients between January 2016 and December 2018 at the Maternity and Children Hospital, Department of Pediatrics, Al Medinah Al Munawarah, Saudi Arabia. Data were extracted from electronic medical record system; patient demographics, medications, frequency of emergency department (ED) and OPD visits. Pearson correlation coefficient, linear regression and independent sample t-test were applied.

Results:

There was no significant correlation (95% CI [-0.013- 0.233]; p=0.07) between the frequency of ED and OPD visits. However, a significant correlation was found between ED visits and missed OPD appointments. Thus, linear regression was applied and indicated that one missed OPD appointment is associated with 1.92 ED visits, (95% CI: 0.19-0.42; p<0.001). Also, a higher rate of ED visits was observed when compared with other studies, with a high ED reliance of 43%.

Conclusion:

This study found that regular OPD visits could improve SCD management, as a directly proportional relationship between the frequency of ED visits and missed OPD appointments were found, along with high ED reliance.

Household material hardships impact emergency department reliance in pediatric patients with sickle cell disease

BACKGROUND

In sickle cell disease (SCD), high emergency department (ED) utilization is associated with worse outcomes and increased costs. A metric called ED reliance (EDr), the percentage of healthcare visits that occur in the ED, attempts to identify ED overutilization. It is unknown if household material hardships (HMH)-housing, utility, or food insecurity-impact reliance on the ED. As these may represent modifiable risk factors for high ED utilization, we aimed to estimate the association between HMH and EDr in pediatric patients with SCD.

METHODS

We reviewed the electronic medical records of pediatric patients with SCD who received care in the Boston Medical Center network in Massachusetts, USA, to collect data on HMH and healthcare utilization. Using linear regression to control for potential confounders, we modeled the association between material hardships and EDr.

RESULTS

Of 101 eligible patients, 60 (59%) reported one or more HMH. The mean EDr was 12% overall, with significant differences between those with and without HMH (15.9 vs 5.9, P = 0.0001). Each additional hardship experienced was associated with an increased average EDr of 7.7 percentage points (R²  = 0.34, P < 0.0001). Housing and utility hardships were each independently associated with increased EDr.

CONCLUSION

HMH are associated with significantly increased EDr in children with SCD, independent of transportation hardship or insurance type. Through screening for HMH, providers and health systems could identify at-risk patients with modifiable risk factors for high EDr in order to provide them additional support.

Factors Associated With Urgent Care Reliance and Outpatient Health Care Use Among Children Enrolled in Medicaid

Importance

Urgent care (UC) centers are a growing option to address children's acute care needs, which may cause unanticipated changes in health care use.

Objectives

To identify factors associated with high UC reliance among children enrolled in Medicaid and examine the association between UC reliance and outpatient health care use.

Design, Setting, and Participants

A retrospective cohort study used deidentified data on 4 133 238 children from the Marketscan Medicaid multistate claims database to calculate UC reliance and outpatient health care use. Children were younger than 19 years, with 11 months or more of continuous Medicaid enrollment and 1 or more UC, emergency department (ED), primary care provider (PCP; physician, advanced practice nurse, or physician assistant; well-child care [WCC] or non-WCC), or specialist outpatient visit during the 2017 calendar year. Statistical analysis was conducted from November 11 to 26, 2019.

Exposures

Urgent care, ED, PCP (WCC and non-WCC), and specialist visits based on coded location of services.

Main Outcomes and Measures

Urgent care reliance, calculated by the number of UC visits divided by the sum of total outpatient (UC, ED, PCP, and specialist) visits. High UC reliance was defined as UC visits totaling more than 33% of all outpatient visits.

Results

Of 4 133 238 children in the study, 2 090 278 (50.6%) were male, with a median age of 9 years (interquartile range, 4-13 years). A total of 223 239 children (5.4%) had high UC reliance. Children 6 to 12 years of age were more likely to have high UC reliance compared with children 13 to 18 years of age (adjusted odds ratio, 1.07; 95% CI, 1.06-1.09). Compared with white children, black children (adjusted odds ratio, 0.81; 95% CI, 0.81-0.82) and Hispanic children (adjusted odds ratio, 0.61; 95% CI, 0.60-0.61) were less likely to have high UC reliance. Adjusted for age, sex, race/ethnicity, and presence of chronic or complex conditions, children with high UC reliance had significantly fewer PCP encounters (WCC: adjusted rate ratio, 0.60; 95% CI, 0.60-0.61; and non-WCC: adjusted rate ratio, 0.41; 95% CI, 0.41-0.41), specialist encounters (adjusted rate ratio, 0.31; 95% CI, 0.31-0.31), and ED encounters (adjusted rate ratio, 0.68; 95% CI, 0.67-0.68) than children with low UC reliance.

Conclusions and Relevance

High UC reliance occurred more often in healthy, nonminority, school-aged children and was associated with lower health care use across other outpatient settings. There may be an opportunity in certain populations to ensure that UC reliance does not disrupt the medical home model.

Preliminary evaluation of the clinical implementation of cognitive-behavioral therapy for chronic pain management in pediatric sickle cell disease

OBJECTIVES

Evaluate the implementation of cognitive-behavioral therapy (CBT) for chronic pain in a clinical setting by comparing youth with sickle cell disease (SCD) who initiated or did not initiate CBT.

DESIGN

Youth with SCD (ages 6-18; n = 101) referred for CBT for chronic pain were compared based on therapy attendance: Established Care; Early Termination; or Comparison (i.e., did not initiate CBT).

SETTING

Outpatient pediatric psychology and comprehensive SCD clinics in 3 locations at a southeastern children's hospital.

INTERVENTIONS

CBT delivery was standardized. Treatment plans were tailored to meet individualized needs.

MAIN OUTCOME MEASURES

Healthcare utilization included pain-related inpatient admissions, total inpatient days, and emergency department reliance (EDR) at 12-months pre-post CBT. Patient-reported outcomes (PROs) included typical pain intensity, functional disability, and coping efficacy pre-post treatment.

RESULTS

Adjusting for age, genotype, and hydroxyurea, early terminators of CBT had increased rates of admissions and hospital days over time relative to comparisons; those who established care had faster reduction in admissions and hospital days over time relative to comparisons. EDR decreased by 0.08 over time for Established Care and reduced by 0.01 for every 1 completed session. Patients who completed pre- and post-treatment PROs reported decreases in typical pain intensity, functional disability, and improved coping efficacy.

CONCLUSIONS

Establishing CBT care may support reductions in admissions for pain, length of stay, and EDR for youth with chronic SCD pain, which may be partially supported by patient-reported improvements in functioning, coping, and lower pain intensity following CBT. Enhancing clinical implementation of multidisciplinary treatments may optimize the health of these youth.

Sickle-Cell Disease Co-Management, Health Care Utilization, and Hydroxyurea Use

BACKGROUND

Sickle-cell disease (SCD) causes significant morbidity, premature mortality, and high disease burden, resulting in frequent health care use. Comanagement may improve utilization and patient adherence with treatments such as Hydroxyurea. The purpose of this study was to describe acute-care utilization in Medicaid-enrolled patients with SCD, patient factors associated with comanagement, and adherence to Hydroxyurea.

METHODS

Data from 2790 patients diagnosed with SCD, age 1 to 65+ years, enrolled at least 1 month in North Carolina Medicaid between March 2016 and February 2017, were analyzed. Outpatient visits were categorized as primary care, hematologist, and nonhematologist specialist. Nurse practitioners or physician assistants with unidentified specialty type or family practice were categorized separately. Comanagement was defined as a minimum of 1 primary care and 1 hematologist visit/patient during the study period.

RESULTS

There were notable age-related differences in utilization of health care services. Only 34.82% of the sample was comanaged. Comanagement was higher in the 1-to-9-year-old (44.88%) and 10-to-17-year-old groups (39.22%) versus the 31-to-45-year-old (30.26%) and 65+-year-old (18.75%) age groups. Age had the greatest influence (AUC = 0.599) on whether or not a patient was comanaged. Only a third of the sample (32.24%) had at least 1 Hydroxyurea (HU) prescription. Age was the most predictive factor of good HUadherence (AUC = 0.6503). Prediction by comanagement was minimal with an AUC = 0.5615.

CONCLUSION

Comanagement was a factor in predicting HUadherence, but further studies are needed to identify the frequency and components of comanagement needed to increase adherence and reduce acute care utilization.

Longitudinal Trend in Emergency Department Reliance for Pain Among Sickle Cell Disease Patients in Wisconsin

Patients with sickle cell disease frequently visit the emergency department for pain. The metric of emergency department reliance (EDR) describes emergency department utilization in relation to all ambulatory visits and serves as a quality of care indicator. This study uses Wisconsin Medicaid data from 2011 to 2015 to examine trend of EDR for pain over the period of 5 years. We stratified our cohort (N=750) by patient ages into 4 groups: (1) children; (2) transition group; (3) young adults; and (4) adults. Using a linear mixed model, we estimated longitudinal trends adjusting for age group and hydroxyurea possession calculated as medication possession ratio. Results show that EDR for pain has distinct temporal patterns for each group. EDR for pediatrics continually remained less than the established threshold of 0.33. The EDR for transition group significantly increased over time; however, the EDR for young adults has significantly decreased since 2011. There were no significant differences in EDR over time for adults older than 30 years. Overall, increase in medication possession ratio was associated with lower EDR. The low EDR for pain among children and the improvements among adults indicate the success of efforts for sickle cell disease patients. However, further interventions are needed for the transition age group.

Pilot Trial of an Emergency Department-based Intervention to Promote Child Passenger Safety Best Practices

BACKGROUND

Despite demonstrated effectiveness of child restraint systems (CRSs), use remains suboptimal. In this randomized pilot trial, we sought to determine the feasibility, acceptability, and potential efficacy of "Tiny Cargo, Big Deal" an ED-based intervention to promote guideline-concordant size-appropriate CRS use.

METHODS

Parents of children < 11 years old were recruited in two EDs and randomized in a 2 × 2 factorial design to four conditions: 1) generic information sheet, 2) tailored brochure mailed after the ED visit, 3) a single motivational interviewing-based counseling session in the ED, and 4) full intervention (counseling session plus tailored brochure). We assessed feasibility (recruitment, completion, follow-up rates) and acceptability (parent attitudes, uptake of information) in the ED, at 1 month and at 6 months. We obtained preliminary estimates of effect sizes of the intervention components on appropriate CRS use at 6-month follow-up.

RESULTS

Of the 514 parents assessed for eligibility, 456 met inclusion criteria and 347 consented to participate. Enrolled parents were mostly mothers (88.1%); 48.7% were 18 to 29 years old; 52.5% were non-Hispanic, white; and 65.2% reported size-appropriate CRS use. Completion rates were 97.7% for baseline survey, 81.6% for counseling, 51.9% for 1-month follow-up, and 59.3% for 6-month follow-up. In the ED, 70.5% rated thinking about child passenger safety in the ED as very helpful. At 1 month, 70.0% expressed positive attitudes toward the study. Of 132 parents who reported receiving study mailings, 78.9% reviewed the information. Parents randomized to the full intervention demonstrated an increase (+6.12 percentage points) and other groups a decrease (-1.69 to -9.3 percentage points) in the proportion of children reported to use a size-appropriate CRS at 6-month follow-up.

CONCLUSIONS

Suboptimal CRS use can be identified and intervened upon during a child's ED visit. A combined approach with ED-based counseling and mailed tailored brochures shows promise to improve size-appropriate CRS use.

Emergency Department Utilization by Native American Children

OBJECTIVES

The aims of this study were to determine differences in emergency department (ED) use by Native American (NA) children in rural and urban settings and identify factors associated with frequent ED visits.

METHODS

This cross-sectional, cohort study examined visits to 6 EDs: 2 rural, 2 midsize urban, and 2 large urban EDs from June 2011 to May 2012. Univariate and multiple regression analyses were conducted. Frequent ED visitors had more than 4 visits in the study period.

RESULTS

We studied 8294 NA visits (5275 patients) and 44,503 white visits (33,945 patients). Rural EDs had a higher proportion of NA patients, those below 200% of the income poverty level, and those who traveled more than 10 miles from their residence to attend the ED (all P < 0.05) compared with midsize and urban EDs. Native American patients had a high proportion of mental health diagnoses compared with whites (4.9% vs 1.9%, P < 0.001). Frequent ED visitors had greater odds of NA race, age younger than 1 year, public insurance, female sex, residence within less than 5 miles from the ED, and chronic disease.

CONCLUSIONS

Native American children seem to have greater challenges compared with whites obtaining care in rural areas. Native American children were more likely to be frequent ED visitors, despite having to travel farther from their residence to the ED. Native American children visiting rural and midsize urban EDs had a much higher prevalence of mental health problems than whites. Additional efforts to provide both medical and mental health services to rural NA are urgently needed.

Hunger: A Missed Opportunity for Screening in the Pediatric Emergency Department

BACKGROUND

The American Academy of Pediatrics and pediatric community recognize the importance of addressing social determinants of health. There are limited data on the prevalence of food insecurity or literature establishing protocols assessing food insecurity in the emergency department (ED).

METHODS

Two anonymous surveys were administered, one to families during their ED visit and another to ED staff to assess perceptions on the ED's role in providing social support.

RESULTS

Thirty-three of 214 respondents (15.4%) reported food insecurity and are associated with economic risk factors ( P < .0001) and a lack of primary care ( P = .008). Overall, 83.2% of the ED staff believed knowing information about families' social risk factors would help patient care and 77.6% believed that the ED staff should address families' social needs.

CONCLUSIONS

Food insecurity affects a significant portion of ED families across income ranges. Screening for food insecurity in the ED is important given association with lack of primary care. Hospital staff supports screening and intervention.

Understanding Pediatric Caretakers' Views on Obtaining Medical Care for Low-acuity Illness

BACKGROUND

A significant proportion of low-acuity emergency department (ED) visits are by patients under 18 years of age. Results from prior interventions designed to reduce low-acuity pediatric ED use have been mixed or poorly sustained, perhaps because they were not informed by patient and caretakers' perspectives. The objective of this study was to explore caretaker decision-making processes, values, and priorities when deciding to seek care.

METHODS

We conducted semistructured interviews of caretakers in both emergency and primary care settings, incorporating stimulated recall methodology. We also explored receptiveness to two care delivery innovations: use of community health workers (CHWs) and video teleconferencing.

RESULTS

Interviews of 57 caretakers identified multiple barriers to accessing primary care for their children's acute illness, including transportation, work constraints, and childcare. Frequent ED users lacked reliable social supports to overcome barriers. Fear of unforeseen health outcomes and a lack of trust in unfamiliar providers also influenced decision-making, rather than lack of general knowledge about minor illness. Receptiveness to CHWs was mixed, reflecting concerns for privacy and level of expertise. The option of video teleconferencing for low-acuity care was well received by caretakers.

CONCLUSIONS

Caretakers who used the ED frequently had limited social support and reported difficulty accessing care when compared to other caretakers. Fear also motivated care seeking and a desire for immediate medical care. Teleconferencing for low-acuity visits may be a useful health care delivery tool to reduce access barriers and provide rapid reassurance without engaging the ED.

Public Health Insurance and Health Care Utilization for Children in Immigrant Families

Objectives To estimate the impacts of public health insurance coverage on health care utilization and unmet health care needs for children in immigrant families. Methods We use survey data from National Health Interview Survey (NHIS) (2001-2005) linked to data from Medical Expenditures Panel Survey (MEPS) (2003-2007) for children with siblings in families headed by at least one immigrant parent. We use logit models with family fixed effects. Results Compared to their siblings with public insurance, uninsured children in immigrant families have higher odds of having no usual source of care, having no health care visits in a 2 year period, having high Emergency Department reliance, and having unmet health care needs. We find no statistically significant difference in the odds of having annual well-child visits. Conclusions for practice Previous research may have underestimated the impact of public health insurance for children in immigrant families. Children in immigrant families would likely benefit considerably from expansions of public health insurance eligibility to cover all children, including children without citizenship. Immigrant families that include both insured and uninsured children may benefit from additional referral and outreach efforts from health care providers to ensure that uninsured children have the same access to health care as their publicly-insured siblings.

Constipation-Related Emergency Department Use, and Associated Office Visits and Payments Among Commercially Insured Children

OBJECTIVE

Pediatric constipation is common, costly, and often managed in the Emergency Department (ED). The objectives of this study were to determine the frequency of constipation-related ED visits in a large commercially insured population, the frequency of an office visit in the month before and after these visits, demographic characteristics associated with these office visits, and the ED-associated payments.

METHODS

Data were extracted from the Truven MarketScan database for commercially insured children from 2012 to 2013. Data on the presence and timing of clinic visits within 30 days before and after an ED constipation visit and demographic variables were extracted. Logistic regression was used to predict an outcome of presence of a visit with independent variables of age, sex, and region of the country.

RESULTS

In a population of 17 million children aged 0 to 17 years, 448,440 (2.6%) were identified with constipation in at least 1 setting, with 65,163 (14.5%) having an ED visit for constipation. Of all children with a constipation-related ED visit, 45% had no office visit in the 30 days before or after the ED visit. Increasing age was associated with absence of an office visit. The median payment by insurance for an ED constipation visit was $523, the median out-of-pocket payment was $100, for a total of $623 per visit.

CONCLUSION

One in 7 children with constipation in this commercially insured population received ED care for constipation, many without an outpatient visit in the month before or after. Efforts to improve primary care utilization for this condition should be encouraged.

Pediatric Emergency Department Utilization and Reliance by Insurance Coverage in the United States

OBJECTIVES

For many children, the emergency department (ED) serves as the main destination for health care, whether it be for emergent or nonurgent reasons. Through examination of repeat utilization and ED reliance (EDR), in addition to overall ED utilization, we can identify subpopulations dependent on the ED as their primary source of health care.

METHODS

Nationally representative data from the 2010 to 2014 Medical Expenditure Panel Survey were used to examine the annual ED utilization of children age 0 to 17 years by insurance coverage. Overall utilization, repeat utilization (two or more ED visits), and EDR (percentage of all health care visits that occur in the ED) were examined using multivariate models, accounting for weighting and the complex survey design. High EDR was defined as having > 33% of outpatient visits in a year being ED visits.

RESULTS

A total of 47,926 children were included in the study. Approximately 12% of children visited an ED within a 1-year period. A greater number of children with public insurance (15.2%) visited an ED at least once, compared to privately insured (10.1%) and uninsured (6.4%) children. Controlling for covariates, children with public insurance were more likely to visit the ED (adjusted odds ratio [aOR] = 1.55, 95% confidence interval [CI] = 1.40-1.73) than children with private insurance, whereas uninsured children were less likely (aOR = 0.64, 95% CI = 0.51-0.81). Children age 3 and under were significantly more likely to visit the ED than children age 15 to 17, whereas female children and Hispanic and non-Hispanic other race children were significantly less likely to visit the ED than male children and non-Hispanic white children. Among children with ED visits, 21% had two or more visits to the ED in a 1-year period. Children with public insurance were more likely to have two or more visits to the ED (aOR = 1.53, 95% CI = 1.19-1.98) than children with private insurance whereas there was no significant difference in repeat ED utilization for uninsured children. Publicly insured (aOR = 1.70, 95% CI = 1.47-1.97) and uninsured children (aOR = 1.90, 95% CI = 1.49-2.42) were more likely to be reliant on the ED than children with private insurance.

CONCLUSIONS

Health insurance coverage was associated with overall ED utilization, repeat ED utilization, and EDR. Demographic characteristics, including sex, age, income, and race/ethnicity were important predictors of ED utilization and reliance.

Urgent Care Utilization in the Pediatric Medicaid Population

OBJECTIVE

To assess healthcare utilization patterns associated with high (≥3 visits/year) urgent care utilization.

STUDY DESIGN

Retrospective analysis of 2 723 792 children who were less than 19 years of age in the 2013 Marketscan Medicaid database. Healthcare utilization categorized as inpatient, emergency department, urgent care, well-child primary care provider (PCP), acute PCP, and specialist visits was documented for 4 groups. We hypothesized that children with high urgent care utilization would have decreased utilization at other sites of care. Multivariable logistic models compared the odds of high urgent care utilization.

RESULTS

Of children in the study population, 92.0% had no urgent care visits; 4.7% had 1; 1.5% had 2; and 1.0% had ≥3. Patient attributes of high urgent care utilization were: ages 1-2 years (aOR = 2.32, 95% CI: 2.18-2.36, reference group: 13-18 years), presence of a complex chronic condition (CCC) (aOR = 1.98, 95% CI: 1.88-2.07, reference group: no CCC) and no CCC but ≥3 chronic conditions (aOR = 2.85, 95% CI: 2.73-2.97, reference group: no CCC, no chronic conditions). High urgent care utilization was associated with ≥5 PCP visits for acute care (aOR = 1.16, 95% CI: 1.11-1.20, reference group: 0 visits), and ≥3 emergency department visits (aOR = 2.15, 95% CI: 2.10-2.23, reference group: 0 visits).

CONCLUSIONS

Increased urgent care utilization was associated with an increase in overall healthcare utilization. Even though those with higher urgent care utilization had more visits for acute care, patients continued to see their PCP for both well-child and acute care visits.

The Impact of Infant Well-Child Care Compliance and Social Risks on Emergency Department Utilization

Deployment of medical and social services at well-child visits promotes child health. A retrospective review of the electronic health record was conducted for infants presenting for their "newborn" visit over a 2-year period at an urban, academic primary care center. Primary outcomes were time to first emergency department (ED) visit, number of ED visits (emergent or nonemergent), and number of nonemergent ED visits by 2 years of life. Records from 212 consecutive newborns were evaluated-59.9% were black/African American and 84.4% publicly insured. A total of 72.6% visited the ED by 2 years of life. Sixty percent received ≥5 well-child visits by 14 months; 25.9% reported ≥1 social risk. There were no statistically significant associations between number of completed well-child visits, or reported social risks, and ED utilization. Renewed focus on preventive care delivery and content and its effect on ED utilization, and other patient outcomes, is warranted.

Development of quality indicators for transition from pediatric to adult care in sickle cell disease: A modified Delphi survey of adult providers

BACKGROUND

Transition from pediatric to adult care is a vulnerable time for young adults with sickle cell disease (SCD); however, improvements in transition are limited by a lack of quality indicators. The purpose of this study was to establish quality indicators for transition in SCD and to determine the optimal timing between the final pediatric visit and the first adult provider visit.

PROCEDURE

We conducted a modified Delphi survey to reach a consensus on which quality indicators are most important for a successful transition. Our expert panel consisted of members of the Sickle Cell Adult Provider Network. In the first round, the participants ranked a list of quality indicators by importance. In the second round, the participants chose their "top 5" quality indicators in terms of importance and also ranked them on feasibility.

RESULTS

The response rates for the two rounds were 68 and 96%, respectively. Nine quality indicators were chosen as "top 5" by a majority of respondents, including communication between pediatric and adult providers, timing of first adult visit, patient self-efficacy, quality of life, and trust with their adult provider. Based on the comments from round 1, respondents were also asked for the optimal timing between leaving pediatric care and entering adult care. Most recommended a first adult visit within 2 months of the final pediatric visit.

CONCLUSIONS

By using these quality indicators chosen by the majority of respondents, we can better develop and evaluate transition programs for young adults with SCD and improve health outcomes for these vulnerable patients.

Frequent users of the pediatric emergency department

OBJECTIVES

Emergency department (ED) crowding is associated with increased morbidity and mortality. Its etiology is multifactorial, and frequent ED use (defined as more or equal to five visits per year) is a major contributor to high patient volumes. Our primary objective is to characterize the frequent user population. Our secondary objective is to examine risk factors for frequent emergency use.

METHODS

We conducted a retrospective cohort study of pediatric emergency department (PED) visits at the Montreal Children's Hospital using the Système Informatique Urgence (SIURGE), electronic medical record database. We analysed the relation between patient's characteristics and the number of PED visits over a 1-year period following the index visit.

RESULTS

Patients totalling 52,088 accounted for 94,155 visits. Of those, 2,474 (4.7%) patients had five and more recurrent visits and accounted for 16.6% (15,612 visits) of the total PED visits. Lower level of acuity at index visit (odds ratio [OR] 0.85) was associated with a lower number of recurrent visits. Lower socioeconomic status (social deprivation index OR 1.09, material deprivation index OR 1.08) was associated with a higher number of recurrent visits. Asthma (OR 1.57); infectious ear, nose, and sinus disorders (OR 1.33); and other respiratory disorders (OR 1.56) were independently associated with a higher incidence of a recurrent visit within the year following the first visit.

CONCLUSION

Our study is the first Canadian study to assess risk factors of frequent pediatric emergency use. The identified risk factors and diagnoses highlight the need for future evidence-based, targeted innovative research evaluating strategies to minimize ED crowding, to improve health outcomes and to improve patient satisfaction.

Comorbidity, Pain, Utilization, and Psychosocial Outcomes in Older versus Younger Sickle Cell Adults: The PiSCES Project

Background. Patients with SCD now usually live well into adulthood. Whereas transitions into adulthood are now often studied, little is published about aging beyond the transition period. We therefore studied age-associated SCD differences in utilization, pain, and psychosocial variables. Methods. Subjects were 232 adults in the Pain in Sickle Cell Epidemiology Study (PiSCES). Data included demographics, comorbidity, and psychosocial measures. SCD-related pain and health care utilization were recorded in diaries. We compared 3 age groups: 16–25 (transition), 26–36 (younger adults), and 37–64 (older adults) years. Results. Compared to the 2 adult groups, the transition group reported fewer physical challenges via comorbidities, somatic complaints, and pain frequency, though pain intensity did not differ on crisis or noncrisis pain days. The transition group utilized opioids less often, made fewer ambulatory visits, and had better quality of life, but these differences disappeared after adjusting for pain and comorbidities. However, the transition group reported more use of behavioral coping strategies. Conclusion. We found fewer biological challenges, visits, and better quality of life, in transition-aged versus older adults with SCD, but more behavioral coping. Further study is required to determine whether age-appropriate health care, behavioral, or other interventions could improve age-specific life challenges of patients with SCD.

Hospital Admission and Emergency Department Utilization in an Infant Medicaid Population

BACKGROUND AND OBJECTIVE

In the first year of life, the rate of rehospitalization for infants has been shown to be between 4.4% and 9.5%. Reducing avoidable health care utilization is a population health priority. The goal of this study was to identify maternal and infant factors associated with rehospitalization and emergency department (ED) utilization in a cohort of newborn Medicaid recipients.

METHODS

A longitudinal database was created by linking mother-infant dyads giving birth at a regional perinatal referral center with Delaware state Medicaid data. Multivariable logistic regression and negative binomial regression were used to examine inpatient hospitalization and ED utilization within 6 months after birth.

RESULTS

The study cohort included 4112 infants; 452 (11.0%) were rehospitalized, and 1680 (41%) used the ED within 6 months of birth. Variables independently associated with inpatient rehospitalization included NICU admission (odds ratio [OR]: 1.7 [95% confidence interval (CI): 1.3-2.3]), maternal bipolar diagnosis (OR: 1.5 [95% CI: 1.1-2.2]), count of maternal prenatal hospital admissions (OR: 1.3 [95% CI: 1.1-1.5]), and count of maternal ED visits (OR: 1.08 [95% CI: 1.04-1.1]). Black race (incident rate ratio [IRR]: 1.2 [95% CI: 1.1-1.3]), fall birth (IRR: 1.2 [95% CI: 1.01-1.3]), count of maternal ED visits (IRR: 1.1 [95% CI: 1.09-1.12]), number of maternal medications (IRR: 1.02 [95% CI: 1.01-1.03]), and maternal age (IRR: 0.97 [95% CI: 0.96-0.98]) were associated with ED utilization.

CONCLUSIONS

In this newborn Medicaid population, multiple maternal factors (including age, race, and mental health diagnoses) were associated with health care utilization in the 6 months after initial hospital discharge. Our data provide potential risk factors for targeted intervention and suggest that maternal factors should be considered in identifying a population at risk for rehospitalization and ED utilization.

Predicting Frequent Emergency Department Use by Pediatric Medicaid Patients

The objective of this study was to determine the patient characteristics and health care utilization patterns that predict frequent emergency department (ED) use (≥4 visits per year) over time to assist health care organizations in targeting patients for care management. This was a retrospective, population-based study of 13,265 Medicaid children aged 0-20 years who were attributed to a single pediatric accountable care organization for at least 2 consecutive years between June 2012 and May 2015. Year-to-year persistence as a frequent ED user was 36.3% (95% confidence interval [CI]: 33.4 to 38.4), which does not support the notion that once a frequent user, always a frequent user. Hence, interventions to reduce frequent ED use may appear to be effective when ED use would have regressed toward the mean without any intervention. At an individual patient level, predictability of frequent ED use was 0.437 (95% CI: 0.358 to 0.485) across frequent ED users of all ages compared with 0.723 (95% CI: 0.435 to 0.824) for those aged <1 year. Accordingly, this latter group may be a better target for interventions than frequent ED users generally.

Health literacy and disease-specific knowledge of caregivers for children with sickle cell disease

This study was conducted to measure the health literacy (HL) and disease-specific knowledge (DSK) of caregivers for children with sickle cell disease (SCD) and relate them to their child's health care utilization. The authors conducted a cross-sectional study of caregiver-child dyads attending an urban pediatric sickle cell clinic. Caregivers were administered the Shortened Test of Functional Health Literacy (S-TOFHLA) and a locally developed DSK questionnaire. Retrospective review of the child's electronic medical record (EMR) was performed to determine annual emergency department (ED) visits and hospitalizations. A total of 142 caregiver-child dyads were recruited for the study. Less than 5% of caregivers had limited HL, with less education (P =.03) and primary language other than English (P =.04) being the only risk factors. Although caregiver HL was not associated with ED visits or hospitalizations, surprisingly DSK was. Caregivers with higher DSK scores had children with higher annual rates of ED utilization (P =.002) and hospitalizations (P =.001), and these children were also more likely to be classified as high ED utilizers (≥4 visits per year; P =.01). Further, caregiver adherence to medication and clinic visits was associated with their child's age (P =.01). Although HL and DSK are both constructs that measure basic health understanding, they differently affect caregivers' ability to navigate and understand the health care system of children with chronic illnesses. This study suggests that the DSK/health care utilization relationship may be a more important measure than HL for programs following children with sickle cell disease and could also have applications in other pediatric chronic diseases.

Adolescents Who Visit the Emergency Department Are More Likely to Make Unhealthy Dietary Choices: An Opportunity for Behavioral Intervention

To identify health behaviors that may be amenable to brief screening and intervention among children in the emergency department (ED), we described the prevalence of health behaviors known to contribute to childhood obesity among middle school students who used the ED recently. Participants included 1590 5th, 7th, and 8th grade students who completed health surveys in 2011. Multivariate logistic regression was used to examine the association between health behaviors and ED use. Children who used the ED reported more unhealthy dietary behaviors, including greater consumption of energy-dense foods such as fried chicken, french fries, and ice cream (OR 1.20, 95% CI 1.06-1.37), fast food (OR 1.07, 95% CI 1.00-1.14) and sugar-sweetened beverages (OR 1.24, 95% CI 1.14-1.35). There was no association with fruit and vegetable consumption, physical activity, or screen time. Unhealthy dietary behaviors are associated with ED use in a low-resource urban population of middle school students.

Defining, quantifying, and characterizing adult frequent users of a suburban Canadian emergency department

Introduction:

Frequent emergency department (ED) users are inconsistently defined and poorly studied in Canada. The purpose of this study was to develop uniform definitions, quantify ED burden, and characterize adult frequent users of a suburban community ED.

Methods:

We retrospectively reviewed the administrative database of the WestView ED in Alberta for patients ≥ 18 years of age presenting during the fiscal year of 2010. Adult frequent users and extreme frequent users were defined as patients with yearly visit numbers greater than the 95th and 99th percentiles, respectively. Demographic information including age, sex, ED length of stay, diagnoses, Canadian Triage and Acuity Scale (CTAS) level, and disposition were collected and stratified by ED frequency of use categories.

Results:

The study included 22,333 ED visits by 14,223 patients. Frequent users represented 3.1% of patients and 13.8% of visits. Extreme frequent users represented 0.8% of patients, 5.4% of visits, and 568,879 cumulative ED minutes (395 days). Nonfrequent users had one to four, frequent users had five or more, and extreme frequent users had eight or more visits over a 12-month period. Frequent users and extreme frequent users had a significantly longer ED length of stay overall and in most age categories. Alcohol-related behavioural disorders, anxiety, nausea/vomiting, and chronic obstructive pulmonary disease were prominent diagnoses, suggesting that psychiatric, somatic, and chronic illnesses may underlie recurrent visits. Admission rates were significantly higher for frequent compared to nonfrequent users.

Conclusions:

We propose reproducible definitions for adult frequent and extreme frequent ED users and provide information on the characteristics and burden of care of these groups at a community Canadian suburban ED. Adoption of these definitions would allow comparison across centres in future research and facilitate targeted interventions for frequent and extreme frequent ED users.

Behavioral Health Screening in Pediatric Primary Care

This pilot study investigated the effect of the Pediatric Symptom Checklist (PSC) on identification of and physician response to behavioral health (BH) concerns. Researchers reviewed 1211 charts of youth aged 4 to 16 years. Records were compared during baseline and an intervention consisting of implementation of the PSC to determine the rate of BH identification and pediatrician response. Access to PSC data resulted in a trivial difference in BH concerns identified by physicians and did not affect physician responses. This case study demonstrates that simply implementing BH screening in primary care may not result in improved outcomes for these children.

Frequent pediatric emergency department use in infancy and early childhood

OBJECTIVE

To define the threshold and population factors associated with pediatric emergency department (PED) use above the norm during the first 36 months of life.

METHODS

We conducted a cross-sectional study of children born between 2003 and 2006, treated in a single PED within the first 36 months of life. Exclusion criteria included out-of-county residence or history of abuse or neglect. The primary outcome, frequent PED use, was defined by the 90th percentile for PED visits per patient. Multivariate analysis was used to identify factors associated with frequent PED use.

RESULTS

A total of 41,912 visits occurred for 16,664 patients during the study. Pediatric ED use skewed heavily toward less than 2 visits per patient (median, 2; range, 1-39; interquartile range, 2). The threshold for frequent PED use was 5 or more visits per patient and occurred for 14% (95% confidence interval [95% CI], 13%-15%) of patients. Most visits were coded with low acuity International Classifications of Diseases, 9th Revision, Clinical Modification codes. The following factors were strongly associated with frequent PED use: lack of primary care physician (odds ratio [OR], 6.03; 95% CI, 5.39%-6.80%; P < 0.0001), non private insurance (OR, 3.64; 95% CI, 2.99%-4.46%; P<0.0001), and history of inpatient admission (OR, 3.09; 95% CI, 1.66%-2.24%; P < 0.0001). Leaving without being seen, black race, Hispanic ethnicity, and residence in a poverty-associated zip code were also significantly associated, but less strongly predictive of, frequent PED use.

CONCLUSIONS

The threshold for frequent PED use was more than 5 visits per patient within the first 36 months of life. Further study is needed to better define this population and develop targeted interventions to ensure care provision occurs in the ideal setting.

The role of medical home in emergency department use for children with developmental disabilities in the United States

OBJECTIVE

Children with developmental disabilities (DDs) have higher rates of emergency department use (EDU) than their typically developing peers do. This study sought to elucidate the relationship between EDU frequency and access to a comprehensive medical home for children with DD.

METHODS

This study conducted multivariate logistic regression analysis on data from the 2005-2006 National Survey of Children with Special Health Care Needs to explore the association between EDU frequency among children with DD and medical home.

RESULTS

Compared with children with DD reporting zero EDU, children with 3 or more EDU were less likely to report access to usual health care source (adjusted odds ratio [AOR], 0.63; 95% confidence interval [CI], 0.45-0.88). Moreover, children with DD who had 3 or more EDU were less likely to have clinicians who listen to parental concerns (AOR, 0.58; 95% CI, 0.45-0.76), demonstrate sensitivity toward family values and customs (AOR = 0.60, 95% CI = 0.46, 0.78), and build meaningful family partnerships (AOR, 0.69; 95% CI, 0.53-0.89).

CONCLUSIONS

The study suggests that children with DD reporting 3 or more EDU per year would likely reduce their EDU by having access to usual source of primary care services and to clinicians with skills in building meaningful partnership with the parents. The inclusion of these medical home attributes in the adoption of patient-centered medical homes with the implementation of the Affordable Care Act presents a mechanism to improve care at lower cost as well as facilitate chronic disease management and coordination between emergency medicine and primary care physicians that may lead to reductions in EDU and unnecessary hospitalization.

Primary care spatial density and nonurgent emergency department utilization: a new methodology for evaluating access to care

OBJECTIVE

To determine the spatial and demographic characteristics of pediatric patients who make nonurgent visits (NUVs) to an urban pediatric emergency department (ED). We hypothesized that the rate of NUVs would be inversely associated with the spatial density of primary care providers (PCPs).

METHODS

A retrospective, cross-sectional analysis was conducted for all visits to Washington, DC's principal pediatric ED between 2003 and 2006. NUVs were defined by a unique algorithm combining resource allocation, ambulatory-sensitive diagnoses, and billing data. Multivariate linear regression analysis was used to determine the association of PCP density and demographic variables on the spatial rate of NUVs.

RESULTS

Over the 4-year period, 35.1% (52,110) of the 148,314 ED visits by Washington, DC, residents were nonurgent. NUVs were most associated with neighborhood median household income <$40,000 and low spatial density of PCPs. For every 1-unit increase in PCP density, the spatial rate of NUVs decreased by 9%. The odds of a visit being nonurgent were significantly higher for African Americans and Hispanics than for whites (odds ratio [OR] 2.4, 95% confidence interval [CI] 2.19-2.64; and OR 2.6, 95% CI 2.36-2.86, respectively), for patients using public insurance versus private (OR 1.46, 95% CI 1.42-1.50), and for patients age <5 years (OR 2.66, 95% CI 2.60-2.72).

CONCLUSIONS

Low spatial density of primary care is strongly associated with nonurgent ED utilization. Improving spatial distribution of primary care may decrease ED misuse and improve access to the medical home.

Medical complexity and pediatric emergency department and inpatient utilization

OBJECTIVES

To characterize the use of and disposition from a tertiary pediatric emergency department (PED) by children with chronic conditions with varying degrees of medical complexity.

METHODS

We conducted a retrospective cohort study using a dataset of all registered PED patient visits at Seattle Children's Hospital from January 1, 2008, through December 31, 2009. Children's medical complexity was classified by using a validated algorithm (Clinical Risk Group software) into nonchronic and chronic conditions: episodic chronic, lifelong chronic, progressive chronic, and malignancy. Outcomes included PED length of stay (LOS) and disposition. Logistic regression generated age-adjusted odds ratios (AOR) of admission with 95% confidence intervals (CIs).

RESULTS

PED visits totaled 77 748; 20% (15 433) of which were for children with chronic conditions. Compared with visits for children without chronic conditions, those for children with chronic conditions had increased PED LOS (on average, 79 minutes longer; 95% CI 77-81; P < .0001) and hospital (51% vs 10%) and PICU (3.2% vs 0.1%) admission rates (AOR 10.3, 95% CI 9.9-10.7 to hospital and AOR 25.0, 95% CI 17.0-36.0 to PICU). Admission rates and PED LOS increased with increasing medical complexity.

CONCLUSIONS

Children with chronic conditions comprise a significant portion of annual PED visits in a tertiary pediatric center; medical complexity is associated with increased PED LOS and hospital or PICU admission. Clinical Risk Group may have utility in identifying high utilizers of PED resources and help support the development of interventions to facilitate optimal PED management, such as pre-arrival identification and individual emergency care plans.

Delayed entry into and failure to remain in HIV care among HIV-infected adolescents

Prompt entry into care and retention in care are critical for improving outcomes among HIV-infected individuals. This study identified factors associated with HIV-infected adolescents who delayed entry into HIV care (DEC) after diagnosis of HIV or who fail to remain in care afterward (FRC). We reviewed clinical, demographic, and social data from the records of 202 HIV-positive adolescents (13-21 years old) infected via high-risk behaviors. Strength of association between clinical and social factors and DEC or FRC were estimated with log-linear regression models. DEC occurred in 38% (76/202) of adolescents. Factors independently associated with DEC were unstable residence (RR 1.5; CI: 1.0-2.1) and, compared with less education, college attendance (RR 2.1; CI: 1.5-3.2). FRC occurred in 29% (52/177) of adolescents established in care. Compared with college attendees, high school students (RR: 4.5; CI: 1.2-17.3) and those who dropped out of high school (RR: 4.0; CI: 1.1-15) were more likely to FRC. Compared with adolescents with private insurance, adolescents without insurance (despite access to free care) were more likely to FRC (RR: 2.8; CI: 1.1-6.9). Controlling for sex, adolescents with children were more likely to FRC (RR: 1.8; CI: 1.0-3.1). Interventions to avoid DEC that target HIV-infected adolescents with unstable residences or those diagnosed while attending college are warranted. Among patients engaged in care, those with only high school education or without insurance-which may be markers for socioeconomic status-need additional attention to keep them in care.

Obesity screening in the pediatric emergency department

OBJECTIVES

The purposes of this study were (1) to examine parental perception of childhood obesity and race with measured body mass index (BMI), (2) to determine if parents are receptive to obesity screening in the pediatric emergency department and if receptivity varies by race or weight status, and (3) to determine eating habits that are predictors of obesity.

METHODS

This study is a cross-sectional study, with a convenience sample of 213 patients (aged 4-16 years accompanied by a parent/legal guardian to a pediatric emergency department). Weight and height were obtained, and parents were asked to complete a survey about perception of their child's weight, nutrition, and exercise habits.

RESULTS

The current study found that parent perception of weight status was fairly accurate, and perception was predictive of BMI. Race, however, was not predictive of BMI. Parents were generally receptive of weight screening in the pediatric emergency department, and this did not vary as a function of weight status; however, receptivity did vary based on ethnicity, with African American parents being more receptive than white parents. Large portion sizes and the number of times a child eats fast food per week were found to be predictive of obesity.

CONCLUSIONS

Greater than half of the children presenting to our pediatric emergency department were overweight or obese. Parents were generally accurate in their perception of their child's weight but were still receptive to obesity prevention and screening in the pediatric emergency department.

Emergency department reliance among rural children in Medicaid in New York State

PURPOSE

This study examines variation in emergency department reliance (EDR) between rural and metro pediatric Medicaid patients in New York State for noninjury, nonpoisoning primary diagnoses and seeks to determine the relationship between receipt of preventive care and the likelihood of EDR.

METHODS

Rural/urban designations were based on Urban Influence Codes established by the United States Department of Agriculture (USDA). Healthcare Effectiveness Data and Information Set (HEDIS(®)) well-visit measures were calculated using 2008 Medicaid claims and encounter data. Well-child numerator status and location of residence variables were then entered as independent variables in multivariate logistic regression models. Models controlled for the effects of Medicaid financing system (fee-for-service vs managed care), Medicaid aid type, race/ethnicity, gender, and 2008 clinical risk group category.

FINDINGS

The likelihood of EDR was higher in all age categories for rural compared to metro residing Medicaid children in New York State. Meeting HEDIS well-child criteria was protective against emergency department (ED) reliance in the adolescence age group (OR = 0.84).

CONCLUSION

ED reliance is associated with rural residence. Increased access to primary and specialty care in rural settings could help reduce EDR, particularly among rural adolescents.
