Urgency of emergency department visits by children with sickle cell disease: a comparison of 3 chronic conditions

Management of Sickle Cell Disease Complications Beyond Acute Chest Syndrome

Sickle cell disease results in numerous complications that can lead to significant morbidity and mortality. Amongst them, acute chest syndrome is the leading cause of mortality. As a result, most providers are in tune with this complication and well versed with management. As sickle cell patients now live longer, they face a multitude of other complications that if left unattended, can lead to significant morbidity and mortality as well. It is critical to look beyond acute chest syndrome and adopt a more comprehensive approach to the management of the sickle cell patient.

Emergency department utilization for sickle cell disease in St. Vincent and the Grenadines

Introduction

sickle cell disease (SCD) is a chronic illness. Individuals affected by this disease are at risk for lifelong complications including episodes of acute pain, chronic pain and multi-organ injury that leads to reduced quality of life and a shortened life span. There is a wealth of data on acute care utilization for SCD in the United States. However, data from the Caribbean region is limited. The objective of this study is to explore Emergency Department (ED) utilization for SCD in St. Vincent and the Grenadines by describing: i) the characteristics of SCD related ED encounters; ii) the urgency of these encounters as defined by resource utilization; iii) the disposition for these ED encounters.

Methods

the study was a cross-sectional study utilizing data from the ED log books at the Milton Cato Memorial Hospital (MCMH) during non-consecutive time periods between January 1^st, 2012 - December 31^st, 2016.

Results

there were 666 SCD-related ED encounters during the study period. Thirty-four percent of encounters resulted in hospitalization and 66% of encounters met criteria for an urgent visit. The most commonly reported diagnosis was vaso-occlusive crisis and accounted for 84% of all encounters. The most frequently documented age group was the 18-30 age category at 43%.

Conclusion

although SCD comprised less than 2% of all ED visits, the majority of these visits could be classified as urgent visits based on resource utilization. This study adds to the emerging data on the burden of this disease in this St. Vincent and the Grenadines.

Emergency Department Utilization for Patients Living With Sickle Cell Disease: Psychosocial Predictors of Health Care Behaviors

Study objective

Individuals living with sickle cell disease (SCD) often require urgent care; however, some patients hesitate to present to the emergency department (ED), which may increase the risk of serious clinical complications. Our study aims to examine psychosocial, clinical, and demographic factors associated with delaying ED care.

Methods

This was a cross-sectional study of 267 adults with SCD from the national INSIGHTS Study. The binary outcome variable asked whether, in the past 12 months, participants had delayed going to an ED when they thought they needed care. Logistic regression was performed with clinical, demographic, and psychosocial measures.

Results

Approximately 67% of the participants reported delaying ED care. Individuals who delayed care were more likely to have reported higher stigma experiences (odds ratio [OR]=1.09; 95% confidence interval [CI] 1.03 to 1.16), more frequent pain episodes (OR=1.15; 95% CI 1.01 to 1.32), lower health care satisfaction (OR= 0.74; 95% CI 0.59 to 0.94), and more frequent ED visits (OR=6.07; 95% CI 1.18 to 31.19). Disease severity and demographics, including sex, age, and health insurance status, were not significantly associated with delay in care.

Conclusion

Psychosocial factors, including disease stigma and previous negative health care experiences, are associated with delay of ED care in this SCD cohort. There is a need to further investigate the influence of psychosocial factors on the health care–seeking behaviors of SCD patients, as well as the downstream consequences of these behaviors on morbidity and mortality. The resulting knowledge can contribute to efforts to improve health care experiences and patient-provider relationships in the SCD community.

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.

Care Coordination for Children With Sickle Cell Disease: A Longitudinal Study of Parent Perspectives and Acute Care Utilization

INTRODUCTION

Care coordination (CC), a core element of the medical home, has the potential to reduce fragmented care and improve patient experience for children with sickle cell disease (SCD). This study aimed to (1) assess CC for pediatric SCD and (2) determine its association with acute care utilization-emergency department encounters and hospitalizations. It was hypothesized that CC would reduce acute care utilization.

METHODS

A longitudinal study of 101 children with SCD was conducted. Parents completed a survey instrument on enrollment. Utilization chart review was conducted 9 months post survey. Outcome variables were emergency department encounters and hospitalizations. Independent variables were parent-reported CC, satisfaction with communication between healthcare providers, and satisfaction with communication between healthcare providers and non-medical providers (e.g., schools, child care centers). Multivariate negative binomial regression was conducted to assess associations between CC and acute care utilization. Data were collected in 2011-2013 and analyzed in 2015.

RESULTS

One third of children had emergency department encounters and 30% had hospitalizations. At enrollment, 25% of parents reported receiving CC help and 20% reported need for extra CC. Most parents were satisfied with communication between physicians but only two thirds were satisfied with communication between their healthcare providers and non-medical providers. No significant associations were found between CC measures and acute care utilization.

CONCLUSIONS

Although parents report multiple CC deficiencies, no associations were found between CC and acute care utilization. Population-based studies are warranted to more definitively determine the association between CC and acute care utilization for children with SCD.

Pediatric Use of Emergency Medical Services: The Role of Chronic Illnesses and Behavioral Health Problems

OBJECTIVE

The increasing use of prehospital emergency medical services (EMS) and its contribution to rising emergency department use and healthcare costs point to the need for better understanding factors associated with EMS use to inform preventive interventions. Understanding patient factors associated with pediatric use of EMS will inform pediatric-specific intervention. We examined pediatric patient demographic and health factors associated with one-time and repeat use of EMS.

METHODS

We reviewed data from Baltimore City Fire Department EMS patient records over a 23-month period (2008-10) for patients under 21 years of age (n = 24,760). Repeat use was defined as involvement in more than one EMS incident during the observation period. Analyses compared demographics of EMS users to the city population and demographics and health problems of repeat and one-time EMS users. Health comparisons were conducted at the patient and incident levels of analysis.

RESULTS

Repeat users (n = 1,931) accounted for 9.0% of pediatric users and 20.8% of pediatric incidents, and were over-represented among the 18-20 year age group and among females. While trauma accounted for approximately one-quarter of incidents, repeat versus one-time users had a lower proportion of trauma-related incidents (7.2% vs. 26.7%) and higher proportion of medical-related incidents (92.6% vs. 71.4%), including higher proportions of incidents related to asthma, seizures, and obstetric/gynecologic issues. In patient-level analysis, based on provider or patient reports, greater proportions of repeat compared to one-time users had asthma, behavioral health problems (mental, conduct and substance use problems), seizures, and diabetes.

CONCLUSIONS

Chronic somatic conditions and behavioral health problems appear to contribute to a large proportion of the repeat pediatric use of this EMS system. Interventions may be needed to engage repeat users in primary care and behavioral health services, to train EMS providers on the recognition and management of behavioral health emergencies, and to improve family care and self-management of pediatric asthma and other chronic conditions.

The proportion of potentially preventable emergency department visits by patients with sickle cell disease

BACKGROUND

Emergency department (ED) visits by children with sickle cell disease (SCD) are often classified as urgent based on resource utilization. This classification may not accurately reflect the potentially preventable nature of SCD visits. We sought to determine the proportion of SCD crisis-related pediatric ED visits that are possibly preventable.

PROCEDURE

We reviewed 2 years of ED visits with a diagnosis of SCD with crisis at a hospital with an established sickle cell program. Criteria for preventable visits were predefined by pediatric hematologists. Non-pain-related chief complaints requiring emergent evaluation or painful episodes preceded by 2 opioid doses were considered not preventable; others were potentially preventable.

RESULTS

The study included 603 visits by 187 patients; 33% were potentially preventable. Overall, 29% of visits were emergent based on non-pain-related emergent complaints. Of the remaining pain-related visits, 26% were preceded by 2 or more doses of opioids at home. Visits by children with asthma were 0.58 times as likely to be preventable, due to more non-pain-related emergent chief complaints (32%) and more children (36%) taking 2 or more opioid doses.

CONCLUSIONS

Approximately two thirds of SCD crisis-related pediatric ED visits are not immediately preventable; that percentage is higher in children with asthma.

Does e-pain plan improve management of sickle cell disease associated vaso-occlusive pain crisis? a mixed methods evaluation

PURPOSE

There is limited application and evaluation of health information systems in the management of vaso-occlusive pain crises in sickle cell disease (SCD) patients. This study evaluates the impact of digitization of paper-based individualized pain plans on process efficiency and care quality by examining both objective patient data and subjective clinician insights.

METHODS

Retrospective, before and after, mixed methods evaluation of digitization of paper documents in Children's Hospital of Pittsburgh of UPMC. Subjective perceptions are analyzed using surveys completed by 115 clinicians in emergency department (ED) and inpatient units (IP). Objective effects are evaluated using mixed models with data on 1089 ED visits collected via electronic chart review 28 months before and 22 months after the digitization.

RESULTS

Surveys indicate that all clinicians perceived the digitization to improve the efficiency and quality of pain management. Physicians overwhelmingly preferred using the digitized plans, but only 44% of the nurses had the same response. Analysis of patient records indicates that adjusted time from analgesic order to administration was significantly reduced from 35.50 to 26.77 min (p<.05). However, time to first dose and some of the objective quality measures (time from administration to relief, relief rate, admission rate, and ED re-visit rate) were not significantly affected.

DISCUSSION

The relatively simple intervention, high baseline performance, and limited accommodation of nurses' perspectives may account for the marginal improvements in process efficiency and quality outcomes. Additional efforts, particularly improved communication between physicians and nurses, are needed to further enhance quality of pain management.

CONCLUSION

This study highlights the important role of health information technology (HIT) on vaso-occlusive pain management for pediatric patients with sickle cell disease and the critical challenges in accommodating human factor considerations in implementing and evaluating HIT effects.

Patient demographic and health factors associated with frequent use of emergency medical services in a midsized city

OBJECTIVES

To optimize health care utilization, health outcomes, and costs, research is needed to improve an understanding of frequent users of emergency health services. Frequent use of emergency services is associated with high costs of health care and may be indicative of challenges accessing, or poor outcomes of, health care. Patient demographics and health factors related to frequent use of the emergency medical services (EMS) system of a midsized city were identified. Study findings will aid in the development of targeted interventions to improve population health.

METHODS

The authors reviewed 9-1-1 call dispatch data and Baltimore City Fire Department (BCFD) EMS records from 2008 through 2010. Frequent use was defined as six or more EMS incidents in the 23-month period. Analyses used census data to compare demographics of EMS users to their population distribution and examined differences in demographics and health problems of frequent EMS users compared to nonfrequent users.

RESULTS

Frequent EMS users (n = 1,969) had a range of six to 199 EMS incidents (mean = 11.2) during the observation period, and although they accounted for only 1.5% of EMS users, they were involved in 12.0% of incidents. Frequent users, compared to nonfrequent users and to the population, were more likely to be male, African American, and 45 years of age or older. Of frequent users, the modal age group was 45 to 54 years, accounting for 29.7% of frequent users, which represented twice this age group's population distribution. Furthermore, this age group had the greatest overrepresentation of males (63.0% of frequent users) and was the peak age group for incidents related to substance abuse (28.0% of frequent users' incidents in this age group). Frequent users, compared to nonfrequent users, had lower levels of incidents related to trauma (5.1% vs. 16.7%) and higher levels of medical incidents (94.8% vs. 82.9%). As proportions of EMS incidents among frequent versus nonfrequent users, respiratory, mental health, and seizure-related incidents were highest in the youngest age groups; substance abuse-related incidents were highest in those middle-aged (35 to 44 and 45 to 54 years). Of health problems, behavioral health (mental health or substance use) contributed most to frequent EMS use (23.4% of frequent users' incidents). Across all incidents, 65.8% of frequent users had indications of behavioral health problems, representing 6.6-fold higher odds than nonfrequent users (22.5%). Frequent compared to nonfrequent users also had higher levels of select chronic conditions (diabetes, 39.9% vs. 14.6%; asthma, 40.9% vs. 13.4%; and HIV, 9.1% vs. 2.4%), with unadjusted odds almost four to seven times higher.

CONCLUSIONS

The study findings revealed the major role of chronic somatic and behavioral health problems in frequent EMS use and that rates of frequent use were highest among those middle-aged, African American, and male. These results suggest the need for coordination of EMS with community-based, integrated medical and behavioral health services to improve access and use of preventive services, with implications for health outcomes and costs. This study demonstrates the value of EMS patient data in identifying at-risk populations and informing novel, targeted approaches to public health interventions.

A randomized, placebo-controlled trial of arginine therapy for the treatment of children with sickle cell disease hospitalized with vaso-occlusive pain episodes

Painful episodes of vaso-occlusion are the leading cause of hospitalizations and emergency department visits in sickle cell disease, and are associated with increased mortality. Low nitric oxide bioavailability contributes to vasculopathy in sickle cell disease. Since arginine is the obligate substrate for nitric oxide production, and an acute deficiency is associated with pain, we hypothesized that arginine may be a beneficial treatment for pain related to sickle cell disease. Thirty-eight children with sickle cell disease hospitalized for 56 episodes of pain were randomized into this double-blinded placebo-controlled trial. Patients received L-arginine (100 mg/kg tid) or placebo for 5 days or until discharge. A significant reduction in total parenteral opioid use by 54% (1.9 ± 2.0 mg/kg versus 4.1 ± 4.1 mg/kg, P=0.02) and lower pain scores at discharge (1.9 ± 2.4 versus 3.9 ± 2.9, P=0.01) were observed in the treatment arm compared to the placebo one. There was no significant difference in hospital length of stay (4.1 ± 01.8 versus 4.8 ± 2.5 days, P=0.34), although a trend favored the arginine arm, and total opioid use was strongly correlated with the duration of the admission (r=0.86, P<0.0001). No drug-related adverse events were observed. Arginine therapy represents a novel intervention for painful vaso-occlusive episodes. A reduction of narcotic use by >50% is remarkable. Arginine is a safe and inexpensive intervention with narcotic-sparing effects that may be a beneficial adjunct to standard therapy for sickle cell-related pain in children. A large multi-center trial is warranted in order to confirm these observations.

The association between hospital type and mortality among critically ill children in US EDs

STUDY AIM

Little is known about the setting of care for critically ill children and whether differences in outcomes are related to the presenting hospital type. This study describes the characteristics of hospitals to which critically ill children present and explores the associations between hospital factors and mortality.

METHODS

This is a retrospective cohort study using data from the 2007 Healthcare Cost and Utilization Project National Emergency Department Sample, representative of all US ED visits. Subjects include children aged 0-18 with ICD9 codes for cardiac arrest, respiratory arrest and/or respiratory failure. Predictor variables include: age, sex, presence of chronic illness, self-pay, public insurance, trauma diagnosis, major trauma center, urban hospital, ED volume and teaching hospital. Multivariate logistic regression estimates predictors of mortality. Analyses integrate clusters, strata, and weights from the probability sample.

RESULTS

There were an estimated 29 million pediatric ED visits in 2007 including 42,036 (0.1%) visits for cardiac or respiratory failure. Teaching hospitals (OR 0.57, 95% CI 0.50-0.66), trauma centers (OR 0.76, 95% CI 0.67-0.86), and urban hospitals (OR 0.78, 95% CI 0.63-0.97) were associated with lower mortality odds. Presence of a chronic illness (OR 14.5, 95% CI 10.5-20.1), diagnosis of an injury (OR 1.2, 95% CI 1.1-1.4) and self-pay status (OR 3.6, 95% CI 2.9-4.4) were associated with increased mortality odds.

CONCLUSIONS

The majority of children with cardiac and respiratory arrest present to urban teaching hospitals and trauma centers. After accounting for important confounders, mortality is lower at teaching hospitals and/or major trauma centers.
