The Association between Educational Attainment and Patterns of Emergency Department Utilization among Adults with Sickle Cell Disease

Health Literacy, Perceived Stigma, Self-Efficacy, and HRQOL in Sickle Cell Disease

Little is known about the relationships among self-efficacy, social determinants of health, and health outcomes in adults living with sickle cell disease (SCD). We conducted mediation analyses examining the relationships among health literacy, perceived stigma, self-efficacy, and health outcomes in an online cohort of adults living with SCD. The health outcomes explored were physical and mental health-related quality of life (HRQOL) and pain interference; covariates included gender, disease severity, and depressive symptoms. Data came from a cross-sectional, descriptive study of 60 adults with SCD. Perceived stigma and self-efficacy had significant relationships with the study outcomes, while health literacy did not. Self-efficacy partially mediated the relationship between perceived stigma and physical HRQOL, when controlling for depressive symptoms. Future research should investigate the influence of stigma and self-efficacy on health outcomes in patients with SCD and consider stigma when creating interventions to modify self-efficacy.

An evaluation of patient-reported outcomes in sickle cell disease within a conceptual model

PURPOSE

To examine the relations between patient-reported outcomes (PROs) within a conceptual model for adults with sickle cell disease (SCD) ages 18 - 45 years enrolled in the multi-site Sickle Cell Disease Implementation Consortium (SCDIC) registry. We hypothesized that patient and SCD-related factors, particularly pain, and barriers to care would independently contribute to functioning as measured using PRO domains.

METHODS

Participants (N = 2054) completed a 48-item survey including socio-demographics and PRO measures, e.g., social functioning, pain impact, emotional distress, and cognitive functioning. Participants reported on lifetime SCD complications, pain episode frequency and severity, and barriers to healthcare.

RESULTS

Higher pain frequency was associated with higher odds of worse outcomes in all PRO domains, controlling for age, gender and site (OR range 1.02-1.10, 95% CI range [1.004-1.12]). Reported history of treatment for depression was associated with 5 of 7 PRO measures (OR range 1.58-3.28 95% CI range [1.18-4.32]). Fewer individual barriers to care and fewer SCD complications were associated with better outcomes in the emotion domain (OR range 0.46-0.64, 95% CI range [0.34-0.86]).

CONCLUSIONS

Study results highlight the importance of the biopsychosocial model to enhance understanding of the needs of this complex population, and to design multi-dimensional approaches for providing more effective interventions to improve outcomes.

Academic Performance of Children With Sickle Cell Disease in the United States: A Meta-Analysis

Background: Students with sickle cell disease are at risk for poor academic performance due to the combined and/or interactive effects of environmental, psychosocial, and disease-specific factors. Poor academic performance has significant social and health consequences. Objective: To study academic achievement and attainment in children with sickle cell disease in the United States. Design: Medline, Embase, SCOPUS, CINAHL, ERIC, and PsycINFO were searched for peer-reviewed articles. Studies of children (ages 5-18) diagnosed with sickle cell disease of any genotype reporting academic achievement (standardized tests of reading, math, and spelling) or attainment (grade retention or special education) outcomes were included. Outcomes were analyzed using a random effects model. Achievement scores were compared to within study controls or normative expectations. Prevalence of grade retention and special education services were compared to national (United States) estimates for Black students. Age at assessment and overall IQ were evaluated separately for association with reading and mathematics scores. Subgroup analyses of reading and math scores were analyzed by cerebral infarct status (no cerebrovascular accident, silent infarct, stroke). Results: There were 44 eligible studies. Students with sickle cell disease scored 0.70, 0.87, and 0.80 (p < 0.001) SD below normative expectations on measures of reading, mathematics, and spelling, respectively. Compared to unaffected sibling and/or healthy controls (k = 8, n = 508), reading and math scores were 0.40 (p = 0.017) and 0.36 (p = 0.033) SD below expectations. Grade retention was approximately 10 times higher in students with sickle cell disease than Black students nationally. Intellectual functioning explained 97.3 and 85.8% of the variance in reading and mathematics performance, respectively (p < 0.001). Subgroup analyses revealed significant differences in reading (p = 0.034) and mathematics (p < 0.001) based on infarct status, with lower performance associated with presence of a silent infarct or stroke. Conclusion: Students with sickle cell disease demonstrate notable academic difficulties and are at high risk for grade retainment. Development of academic interventions and increased access to school support services are needed for this vulnerable population.

Health-related quality of life and neuropathic pain in sickle cell disease in Jamaica

BACKGROUND

Health related quality of Life (HRQOL) is an important consideration when managing chronic diseases, like sickle cell disease (SCD). Assessment of neuropathic pain (NP) and its association with HRQOL in SCD are rarely reported.

OBJECTIVES

To examine the prevalence of NP and its association with HRQOL in adult Jamaicans with SCD.

METHODS

Adult SCD patients were recruited consecutively and data were collected on socio-demographics, NP using Douleur Neuropathique 4 (DN4), and HRQOL using the Adult Sickle Cell Quality of Life Measurement Information System (ASCQ-Me). Means, medians, t-tests, ANOVA tests, Wilcoxon Rank-sum tests, Kruskal-Wallis tests, Pearson's correlation and multivariate linear regression analyses were performed using STATA 14.2.

RESULTS

There were 236 respondents, with 56.8% female, mean age 33.2 years (SD: 11.6; range: 18-67 years), and 75% had homozygous SS genotype. NP was likely present in 26.7% of the population. The standardized ASCQ-Me (mean ± SD; ordered from lowest to best HRQOL domain scores) were: emotional impact 53.3 ± 10.1; sleep impact 56.1 ± 9.7; social function 57.7 ± 10.6; pain impact 58.6 ± 7.8; and stiffness impact 61.0 ± 7.3. On multivariate analyses, NP significantly reduced emotional and social functioning and worsened sleep and stiffness. Higher acute pain scores significantly worsened all HRQOL domains, while higher disease severity worsened all except stiffness. Obesity was associated with worse sleep and greater stiffness. Females with leg ulcers reported lower social functioning and unemployed females had greater pain impact.

CONCLUSIONS

NP is increasingly prevalent in SCD and worsens HRQOL. Gender specific studies are needed to understand the significantly poorer HRQOL in women.

Impact of sickle cell disease on patients' daily lives, symptoms reported, and disease management strategies: Results from the international Sickle Cell World Assessment Survey (SWAY)

Sickle cell disease (SCD) is a genetic disorder, characterized by hemolytic anemia and vaso‐occlusive crises (VOCs). Data on the global SCD impact on quality of life (QoL) from the patient viewpoint are limited. The international Sickle Cell World Assessment Survey (SWAY) aimed to provide insights into patient‐reported impact of SCD on QoL. This cross‐sectional survey of SCD patients enrolled by healthcare professionals and advocacy groups assessed disease impact on daily life, education and work, symptoms, treatment goals, and disease management. Opinions were captured using a Likert scale of 1‐7 for some questions; 5‐7 indicated “high severity/impact.” Two thousand one hundred and forty five patients (mean age 24.7 years [standard deviation (SD) = 13.1], 39% ≤18 years, 52% female) were surveyed from 16 countries (six geographical regions). A substantial proportion of patients reported that SCD caused a high negative impact on emotions (60%) and school achievement (51%) and a reduction in work hours (53%). A mean of 5.3 VOCs (SD = 6.8) was reported over the 12 months prior to survey (median 3.0 [interquartile range 2.0‐6.0]); 24% were managed at home and 76% required healthcare services. Other than VOCs, fatigue was the most commonly reported symptom in the month before survey (65%), graded “high severity” by 67% of patients. Depression and anxiety were reported by 39% and 38% of patients, respectively. The most common patient treatment goal was improving QoL (55%). Findings from SWAY reaffirm that SCD confers a significant burden on patients, epitomized by the high impact on patientsʼ QoL and emotional wellbeing, and the high prevalence of self‐reported VOCs and other symptoms.

Risk factors associated with increased emergency department utilization in patients with sickle cell disease: a systematic literature review

Sickle cell disease (SCD), a genetic disorder affecting up to 100,000 patients in the USA, impacts multiple organ systems. The emergency department (ED) is frequently utilized by patients with SCD who have severe pain from vaso-occlusive crises. The goal of this systematic literature review is to identify predictors for ED use among patients with SCD in the USA, as high ED reliance is not ideal because of the potential for discontinuity of care as well as higher costs. PubMed and Embase were searched for articles containing the keywords "sickle cell disease" AND ("emergency" OR "acute care") AND ("utilization" OR "health care") published between 2000 and 26 September 2019. A total of 26 publications were identified meeting the following inclusion criteria: report of ED or acute care clinic use; report of health care utilization for SCD; and report of ED visits independent of hospital admission, ED revisits, inpatient care visits, and SCD care unit visits. Articles unavailable in English or those focused on populations outside the USA were excluded. Of the 26 articles included, 4 were prospective and the remainder were retrospective. Qualitative analysis of the articles revealed a higher rate of ED utilization among adults than children, patients with public insurance than private insurance, and patients with more comorbidities, complications, or pain. Age and pain levels were both commonly cited as predictors of ED utilization. Additional prospective and interventional studies are needed to further define predictors of ED utilization and to uncover treatments that decrease ED visits.

A welfare-theoretic model consistent with the practice of cost-effectiveness analysis and its implications

I look at three debates in the health economics literature in the context of cost-effectiveness analysis (CEA): 1) inclusion of future costs, 2) discounting, and 3) consistency with a welfare-economic perspective. These debates thus far have been studied in isolation leading to confusion and lingering questions. I look at these three debates holistically and present a welfare theoretic model that is consistent with the practice of CEA and can help inform all of these three debates. It shows rationales for the recommendations of the Second Panel and clarifies some nuanced implications for the practice of CEA when taking a societal perspective in the context of distributional CEA and multi-sectorial budgets.

Social Determinants of Health and Emergency Department Use Among Children With Sickle Cell Disease

Sickle cell disease (SCD) is associated with disproportionate emergency department (ED) use. This study described the social determinants of health associated with ED visits and hospital admission from the ED among children with SCD using a nationally representative dataset. We analyzed data from 126 children 0 to 17 years of age with SCD included in the 2011 to 2017 rounds of the National Health Interview Survey (mean age, 8 y; 50% female individuals; 74% African American). Study variables were summarized using weighted means and proportions and compared according to ED use and admission by Wald tests. Fifty-two identified children had visited the ED within the last 12 months and 21 were admitted to the hospital after their most recent ED visit. Children living in a single-mother household were more likely to visit the ED (P=0.040), as were younger children (mean age, 6 vs. 9 y; P=0.034), with no evaluated social determinants of health significantly impacting hospital admission from the ED. The lack of association between ED use and either poverty or insurance type may be related to the overall high level of social disadvantage among children with SCD. Our findings demonstrate the need to better characterize specific social factors impacting acute care use among children with SCD.

Social and Behavioral Factors in Sickle Cell Disease: Employment Predicts Decreased Health Care Utilization

THE PURPOSE

to determine frequency of health care encounters among people with sickle cell disease (SCD) seeking treatment for a vaso-occlusive crisis (VOC). Health care encounters are categorized by visit type (day hospital, ED visit, hospitalization), prevalence of self-reported behavioral and social factors, and any associations between behavioral and social factors and health care encounters. Ninety-five people with SCD were enrolled in a prospective descriptive study in North Carolina. Patients were interviewed concerning behavioral-social factors, and a report of health care encounters was produced, generated by ICD codes associated with VOCs between October 2011 and March 2014. Among 95 patients, there were a total of 839 day hospital and 1,990 ED visits, and 1,101 hospital admissions. Prevalent behavioral and social factors were depression (29%), anxiety (34%), illicit drug use (6%); unstable home situation (17%); and unemployment (81%). Employment and stable home were significantly associated with decreased frequency of health care encounters.

Persistently Frequent Emergency Department Utilization Among Persons With Systemic Lupus Erythematosus

OBJECTIVE

In order to identify opportunities to improve outpatient care, we evaluated patients with systemic lupus erythematosus (SLE) who persistently frequent the emergency department (ED).

METHODS

We conducted a retrospective study of patients with SLE who frequented the ED for ≥3 visits in a calendar year, from 2013 to 2016. Persistent users were those who met criteria for persistent use for at least 2 of the 4 years, and limited users for 1 of the 4 years. Each ED encounter was categorized as SLE-related, infection-related, pain-related, or other. We compared ED use between persistent and limited users, and analyzed factors associated with pain-related encounters among persistent users through multivariate logistic regression.

RESULTS

We identified 77 participants who had 1,143 encounters as persistent users, and 52 participants who had 335 encounters as limited users. Persistent users accounted for 77% of ED use by patients with SLE who frequented the ED. Pain-related ED visits were more common among persistent users (32%) than limited users (18%). Among persistent users, most pain-related encounters were discharged from the ED (69%) or within 48 hours of admission (20%). Persistent users with pain-related encounters accounting for >10% of ED use were more likely to be obese, have fewer comorbid conditions, and be on long-term opioid therapy.

CONCLUSION

Pain is a major cause of ED use. Patients with SLE who persistently utilize the ED for pain are likely to be noncritically ill, as evidenced by frequent discharges from the ED and short-stay admissions. Patients with SLE who persistently frequent the ED for pain represent a viable target for interventions to improve outpatient quality of care.

Using Qualitative Perspectives of Adolescents with Sickle Cell Disease and Caregivers to Develop Healthcare Transition Programming

Youth with sickle cell disease (SCD) are living longer, requiring transition from pediatric to adult health care. Transition programs have been created to improve transition readiness and help patients take responsibility for their health. The aim of this study was to explore the usefulness of current transition materials and identify unmet transition needs from the perspective of adolescents with sickle cell disease (SCD) and caregivers to refine transition programming and interventions. Focus groups were conducted with 14 adolescents with SCD (Mean age = 14.6 years, SD = 1.9) and 20 caregivers (Mean age = 43.2 years, SD = 9.3) to gather perspectives about transition to adult care, current transition program materials and recommendations for future programming. Four themes emerged: (a) transition skills and knowledge needs, (b) change in health care responsibility, (c) concerns with adult SCD care, and (d) useful transition readiness strategies and resources. The findings of this study were used to develop Web based educational modules, experiential transition skills learning, and an adolescent and caregiver hematology support group. Findings highlight the need to conduct periodic readiness assessments, provide opportunities and scaffolding to learn skills based on readiness level, and help build social support networks to encourage and facilitate learning.
