School Performance and Disease Interference in Adolescents with Sickle Cell Disease

Impact of hospitalization for vaso-occlusive crisis on health-related quality of life in children with sickle cell disease

BACKGROUND

Sickle cell disease (SCD) is characterized by vaso-occlusive crises (VOCs) that impair the health-related quality of life (HRQoL). The aim of this study is to evaluate the impact of hospitalization for VOCs on HRQoL in children with SCD over time.

METHODS

In this longitudinal cohort study, children aged 8-18 years diagnosed with SCD at the Amsterdam UMC were included between 2012 and 2021. HRQoL was annually measured as part of standard care using the Pediatric Quality of Life Inventory. The impact of hospitalization for VOC on HRQoL was evaluated using linear mixed models 3, 6, 9, and 12 months after hospitalization. The effect of frequency of hospitalization for VOC on HRQoL was evaluated over the last 12 months.

RESULTS

In total, 94 children with SCD were included with a median age of 11.8 years (interquartile range [IQR]: 9-14). Thirty-seven patients (39%) had been hospitalized for a VOC. Hospitalization for VOC led to a decrease of 3.2-4.8 points in total HRQoL compared to patients without hospitalization, most pronounced 3 months after hospitalization. Recurrent admission for VOC in the last 12 months was associated with a decrease of 2.3 points in total HRQoL (p = .04). The most affected subscale was physical functioning.

CONCLUSION

The adverse effects of hospitalization for VOC in children with SCD persist up to 12 months after hospitalization. After hospitalization for VOC, extra attention and support for its negative impact on HRQoL are recommended. This study also underlines the importance of systematically measuring HRQoL, allowing clinicians to intervene accordingly.

Education Liaison improves implementation of school accommodations for students with sickle cell disease

BACKGROUND

Children with sickle cell disease (SCD) have lower academic attainment than healthy peers. Many benefit from neuropsychological testing (NPT) and educational accommodations, including Individualized Education Programs (IEPs) and Section 504 plans (504s). Despite medical barriers to academic attainment, many children with SCD do not receive indicated NPT or accommodations.

OBJECTIVE

We hypothesize that a dedicated Education Liaison (EL) embedded in the SCD team increases implementation of NPT and accommodations.

STUDY DESIGN

This retrospective study included children aged 5-20 years with SCD receiving care at a single center from 2017 through 2020. Univariate analysis and multiple logistic regression were performed.

RESULTS

Total 316 children with SCD were included. At baseline, 52.8% had accommodations (IEP: 24.4%, 504: 38.0%). The EL interacted with 62.0% of children. Children with EL contact were more likely to undergo NPT (odds ratio [OR]: 5.385), have an IEP (OR: 4.580), and have a 504 (OR: 2.038) (p < .001 for all). At the end of the study period, 64.6% had accommodations (IEP: 33.5%, 504: 54.4%), which increased from baseline (p < .001 for all). EL interaction was associated with overt or silent stroke history (OR: 1.911), acute chest syndrome history (OR: 2.257), hospitalizations since age 5 (OR: 3.216), and hospitalization for vaso-occlusive pain since age 5 (OR: 2.226) (p < .001 for all).

CONCLUSION

EL interaction improves access to NPT and educational accommodations among children with SCD. SCD centers should incorporate ELs in comprehensive care teams to improve access to appropriate educational accommodations.

Chronic pediatric diseases and risk for reading difficulties: a narrative review with recommendations

Literacy is a major social determinant of health, rooted in skills that develop during early childhood. Children arriving at kindergarten unprepared to learn to read are more likely to have low reading proficiency thereafter. General and health literacy are highly correlated, affecting understanding of health conditions, treatment adherence, and transition to self-care and adult healthcare services. The American Academy of Pediatrics (AAP) recommends literacy and school readiness promotion during well-visits and neurodevelopmental surveillance is emphasized across primary and subspecialty care. While genetic and environmental risk factors for reading difficulties are well-established, risks related to complex and chronic medical conditions are less appreciated and under-researched. This review applies an eco-bio-developmental framework to explore literacy across five complex chronic conditions affecting millions of children worldwide: asthma, cancer, congenital heart disease, epilepsy, and sickle cell disease. In each, integration of an efficient reading brain network may be impacted by direct factors, such as ischemia, anesthesia, and/or medications, and also indirect factors, such as altered parent-child routines, hospital stays, and missed school. By integrating literacy into care management plans for affected children, pediatric primary care and specialty providers are poised to identify risks early, target guidance and interventions, and improve academic and health outcomes. IMPACT: While genetic and environmental risk factors for reading difficulties are well-established, risks related to complex and/or chronic medical conditions such as asthma, cancer, congenital heart disease, epilepsy, and sickle cell disease are substantial, less appreciated, and under-researched. General and health literacy are highly correlated, with implications for the understanding one's health condition, treatment adherence, and transitioning to self-care, which is especially important for children with complex and/or chronic illness. Pediatric primary care and specialty providers are poised to integrate reading and literacy into care management plans for children with complex and/or chronic illness, including early screening, guidance, support, and interventions.

The distinct longitudinal impact of pain catastrophizing on pain interference among youth living with sickle cell disease and chronic pain

Youth living with chronic sickle cell disease (SCD) pain are at risk for psychosocial distress and high levels of pain catastrophizing that contribute to functional impairment. This study aimed to identify the unique long-term impact of pain catastrophizing on pain impairment among youth with SCD. Youth with chronic SCD pain (N = 63, 10-18 years old, 58.3% female, 95.1% Black or African American) were recruited within comprehensive SCD clinics and completed a battery of measures at baseline and 4-months follow-up. A linear hierarchical regression examined baseline demographic and clinical characteristics (child SCD genotype, age, and average pain intensity), psychosocial functioning (anxiety, depression), and pain catastrophizing as predictors of pain interference at 4-months follow-up. Pain catastrophizing was the only unique predictor of pain interference at 4-months follow-up. Among youth with chronic SCD pain, pain catastrophizing warrants greater consideration as an important predictor that influences pain management and overall functioning.

Burden of disease, treatment utilization, and the impact on education and employment in patients with sickle cell disease: A comparative analysis of high- and low- to middle-income countries for the international Sickle Cell World Assessment Survey

The international Sickle Cell World Assessment Survey (SWAY) reported a high impact of sickle cell disease (SCD) on patients' daily lives globally. In this study, we analyzed whether the reported burden differed between patients from the USA (n = 384) and other high‐income (HI; n = 820) or low‐ to middle‐income (LMI; n = 941) countries. We assessed symptoms and complications, incidence/management of vaso‐occlusive crises (VOCs), treatment utilization/satisfaction, and the impact of SCD on education/employment. Certain symptoms (bone aches, insomnia, and joint stiffness) and complications (swollen/painful fingers/toes, gallstones, vision problems, blood clots, and asthma) were reported proportionally more by patients in the USA than in the HI/LMI countries. Self‐reported VOCs were more common (mean [SD]: 7.1 [5.7] vs. 5.5 [8.9] and 4.4 [4.6] in the previous 12 months) and were managed more often by hospitalization (52% vs. 24% and 32%) in the USA than the HI and LMI countries. A higher proportion of patients from the USA than the HI/LMI countries reported a negative impact of SCD on their employment/schooling. Although high overall satisfaction with current treatments was reported globally, most patients indicated a strong desire for alternative pain medications. There are likely several reasons for the relatively high patient‐reported burden in the USA group compared with the HI/LMI countries, including an older population and differences in newborn screening programs and pediatric/adult transition of care. It is clear that there is an urgent need for improved understanding and management of SCD globally, not just in the USA.

The Impact of Sickle Cell Disease on Academic Performance among Affected Students

Background: Sickle cell disease (SCD) is a genetic disease that is highly prevalent in Jazan Province, Saudi Arabia, and is mostly characterized by many complications such as vaso-occlusive crises (VOC), acute chest syndrome (ACS) and well-documented neurological complications. These complications may affect patients’ academic performance. Methods: An observational, cross-sectional, retrospective study was conducted in Jazan Province. General and demographic data were collected and questions about academic performance of students with SCD were answered. Both t-tests and chi-square tests, along with multiple logistic regression, were used for analysis. Results: 982 participants were selected for this study with a mean age of 23 years (SD: 7). Most of the participants were female (64%). The number of participants with SCD was 339 (36%), of whom 42% were male. Students with SCD recorded lower grade point averages (GPA) and more absences compared to healthy participants. Further, about 60% of students with SCD thought they performed better than 40% of the participants without SCD during the COVID-19 pandemic when most of the educational activities were online. Conclusion: As has been previously reported, this study suggested that the academic performance of students with SCD is negatively affected compared to healthy individuals, and this is mostly due to complications associated with the disease. Further, students with SCD acknowledged better performance with online education, an option that should be considered to improve their academic performance. National studies on a larger population are required by health and education officials, and supportive online educational programs are warranted to enhance the academic performance of this population.

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.

Transitions to Postsecondary Education in Young Adults with Hemoglobinopathies: Perceptions of Patients and Staff

Supplemental Digital Content is available in the text.

The transition from high school to postsecondary education can be challenging for adolescents and young adults (AYAs) with chronic health conditions. AYAs with hemoglobinopathies, including sickle cell disease, are a particularly vulnerable group whose academic performance is impacted by unpredictable disease symptoms. AYA with hemoglobinopathies may require academic accommodations to promote postsecondary success; however, accessing appropriate supports can be complicated.

Nutritional and Hematological Status of Sudanese Women of Childbearing Age with Steady-state Sickle Cell Anemia

OBJECTIVES

We sought to investigate the nutritional and hematological status of Sudanese women of childbearing age with sickle cell anemia (SCA). Anthropometry and hematology were used to assess nutritional status and health and disease conditions, respectively.

METHODS

Women with steady-state (HbSS, n = 39; age = 19.0±2.7) and without (HbAA, n = 36; age, 19.8±2.7) SCA were recruited during a routine visit to the Hematology Clinic, Ibn-Auf Teaching Hospital, Khartoum, Sudan.

RESULTS

The two groups of women lived in similar environmental conditions and ate similar diets three times a day. However, despite taking regular meals, the women with sickle anemia were thinner and lighter (p < 0.001) and shorter (p = 0.002) compared with those who do not have the disease. Also, they had higher levels of mean corpuscular hemoglobin (Hb) concentration and white cell count (p < 0.001), mean corpuscular volume (p = 0.003), and platelet (p = 0.002) and lower packed cell volume and Hb (p < 0.001). There was no difference in levels of anthropometric and hematological variables between the hydroxyurea treated and untreated SCA patients (p > 0.050).

CONCLUSIONS

The low anthropometric (height, weight, and body mass index) and abnormal hematological values in the women with SCA in steady-state reflect sustained nutritional insults inflected by the disease and poverty. Tailored nutritional counseling/advice must be an integral part of managing patients with SCA. Such advice is particularly vital for women of childbearing age because of the adverse effects of prepregnancy nutritional deficiency on outcomes.

Academic Challenges and School Service Utilization in Children with Sickle Cell Disease

OBJECTIVES

To describe the academic concerns and risk strata of children with sickle cell disease (SCD) as identified through a parent-directed screening tool and to compare the rates of these concerns with actual school service utilization in the clinic population.

STUDY DESIGN

We completed a retrospective review of patients with SCD referred to the school intervention program during the 2017-2018 and 2018-2019 school years because of a school-related concern raised by parents or noted by the clinical team. All parents completed the Brief School Needs Inventory (BSNI), a validated parent-response tool used to stratify academic risk. Rates of special education services, grade retention, and results from neuropsychologic testing were captured. Clinical history, the use of disease-modifying therapy, and results from laboratory and neuroimaging studies were also obtained. Descriptive statistics were performed to examine demographic information, clinical history, and BSNI results.

RESULTS

In total, 137 unique patients (age range, 14 months to 19 years) completed the BSNI during the study period, for 181 events. According to BSNI risk-stratification, 45% of patients were deemed low, 36% moderate, and 19% high academic risk. Over one-half of parents were concerned about their ability to advocate for their child's needs. Despite legal qualification for a Section 504 accommodation plan, only 20% had established plans. Academic concerns were common with 31% of children reporting an individualized education program and 20% with grade retention/remediation.

CONCLUSIONS

Concerns for academic challenges remain high among parents of children with SCD; however, school service utilization remains disproportionately low attributable to numerous reasons.

Cognitive performance as a predictor of healthcare transition in sickle cell disease

Neurocognitive deficits in sickle cell disease (SCD) may impair adult care engagement. We investigated the relationship between neurocognitive functioning and socio-environmental factors with healthcare transition outcomes. Adolescents aged 15-18 years who had neurocognitive testing and completed a visit with an adult provider were included. Transition outcomes included transfer interval from paediatric to adult care and retention in adult care at 12 and 24 months. Eighty adolescents (59% male, 64% HbSS/HbSβ⁰ -thalassaemia) were included. Mean age at adult care transfer was 18·0 (±0·3) years and transfer interval was 2·0 (±2·3) months. Higher IQ (P = 0·02; P_FDR  = 0·05) and higher verbal comprehension (P = 0·008; P_FDR  = 0·024) were associated with <2 and <6 month transfer intervals respectively. Better performance on measures of attention was associated with higher adult care retention at 12 and 24 months (P = 0·009; P_FDR  = 0·05 and P = 0·04; P_FDR  = 0·12 respectively). Transfer intervals <6 months were associated with smaller households (P = 0·02; P_FDR  = 0·06) and households with fewer children (P = 0·02; P_FDR  = 0·06). Having a working parent was associated with less retention in adult care at 12 and 24 months (P = 0·01; P = 0·02 respectively). Lower IQ, verbal comprehension, attention difficulties and environmental factors may negatively impact transition outcomes. Neurocognitive function should be considered in transition planning for youth with SCD.

Exploring the Needs of Adolescents With Sickle Cell Disease to Inform a Digital Self-Management and Transitional Care Program: Qualitative Study

BACKGROUND

Accessible self-management interventions are critical for adolescents with sickle cell disease to better cope with their disease, improve health outcomes and health-related quality of life, and promote successful transition to adult health care services. However, very few comprehensive self-management and transitional care programs have been developed and tested in this population. Internet and mobile phone technologies can improve accessibility and acceptability of interventions to promote disease self-management in adolescents with sickle cell disease.

OBJECTIVE

The aim of this study was to qualitatively explore the following from the perspectives of adolescents, parents, and their health care providers: (1) the impact of sickle cell disease on adolescents to identify challenges to their self-management and transitional care and (2) determine the essential components of a digital self-management and transitional care program as the first phase to inform its development.

METHODS

A qualitative descriptive design utilizing audio-recorded, semistructured interviews was used. Adolescents (n=19, aged 12-19 years) and parents (n=2) participated in individual interviews, and health care providers (n=17) participated in focus group discussions and were recruited from an urban tertiary care pediatric hospital. Audio-recorded data were transcribed verbatim and organized into categories inductively, reflecting emerging themes using simple content analysis.

RESULTS

Data were categorized into 4 major themes: (1) impact of sickle cell disease, (2) experiences and challenges of self-management, (3) recommendations for self-management and transitional care, and (4) perceptions about a digital self-management program. Themes included subcategories and the perspectives of adolescents, parents, and health care providers. Adolescents discussed more issues related to self-management, whereas health care providers and parents discussed issues related to transition to adult health services.

CONCLUSIONS

Adolescents, parents, and health care providers described the continued challenges youth with sickle cell disease face in terms of psychosocial impacts and stigmatization. Participants perceived a benefit to alleviating some of these challenges through a digital self-management tool. They recommended that an effective digital self-management program should provide appropriate sickle cell disease-related education; guidance on developing self-advocacy and communication skills; empower adolescents with information for planning for their future; provide options for social support; and be designed to be engaging for both adolescents and parents to use. A digital platform to deliver these elements is an accessible and acceptable way to address the self-management and transitional care needs of adolescents.
