Article Synopsis
  • The study aims to identify clinical laboratory markers associated with postacute sequelae of SARS-CoV-2 infection (PASC) due to a lack of validated biomarkers.
  • Conducted with 10,094 participants across 83 sites, the research compared laboratory measures between those with and without prior SARS-CoV-2 infection and analyzed the impact of PASC indices on these measures.
  • Results showed participants with prior infection had lower platelet counts and higher levels of hemoglobin A and urinary albumin-creatinine ratio, but these differences were minor and not significant among those with PASC.

Health care transitions (HCT) from pediatric to adult health care remain a challenge for children and youth with special health care needs (CYSHCN), their families and their clinicians. While the HCT literature has expanded, gaps remain in how to improve health outcomes during transitions. HCTs broadly encompass three key domain areas: transition planning, transfer to adult health care clinicians or an adult model of care, and integration into an adult care/model of care.

The COVID-19 (coronavirus disease 2019) pandemic brought rapid expansion of pediatric telehealth to maintain patient access to care while decreasing COVID-19 community spread. We designed a retrospective, serial, cross-sectional study to investigate if telehealth implementation at an academic pediatric practice led to disparities in health care access. Significant differences were found in pre-COVID-19 versus during COVID-19 patient demographics.

Objective: To identify opportunities to improve care value for children with disabilities (CWD), we examined CWD prevalence within a commercially insured population and compared outpatient care quality and annual health plan spending levels for CWD relative to children with complex medical conditions without disabilities; children with chronic conditions that are not complex; and children without disabling, complex, or chronic conditions.

Methods: This cross-sectional study comprised 1,118,081 person-years of Blue Cross Blue Shield Massachusetts data for beneficiaries aged 1 to 19years old during 2008 to 2012. We combined the newly developed and validated Children with Disabilities Algorithm with the Pediatric Medical Complexity Algorithm to identify CWD and non-CWD subgroups.

Background and Objectives Pediatricians face numerous challenges in providing care for children with special health care needs (CSHCN). Few studies have described health care resources available to support pediatricians to care for CSHCN. This study investigated available resources to care for CSHCN and factors associated with having a greater proportion of CSHCN in practice.

As health care continues to evolve, the need for more effective health care transition (HCT) for all youth, but particularly children with chronic conditions and special health care needs, becomes even more important. With more than 90% of adolescents with chronic medical conditions now surviving into adulthood, suboptimal transition can lead to poorer quality of life and less successful adulthood.Through a series of clinical vignettes, the challenges of HCT are presented herein and accompanied by comments that underscore how these adolescents can best be helped to transition to successful adulthood.

Background: Pediatric patients can present to a medical facility and subsequently be transferred to a different hospital for definitive care. Interfacility transfers require a provider handoff across facilities, posing risks that may affect patient outcomes.

Objectives: The goal of this study was to describe the thoroughness of information transmission between providers during interfacility transfers, to describe perceived errors in care at the posttransfer facility, and to identify potential associations between thoroughness of information transmission and perceived errors in care.

Background And Objectives: Children with special health care needs (CSHCN) have frequent hospitalizations and high specialty care utilization. If they initially present to a medical facility not capable of providing their definitive care, these children often experience an interfacility transfer. This transition has potential to impose hardships on familial caregivers.

Advances in cystic fibrosis (CF) care transformed the condition from one considered lethal by age 7 into a chronic illness (median lifespan, >40 years). With the growing numbers of adults with CF voicing their preference for care in age appropriate settings, the CF community met the challenge by developing an adult-focused care system modeled on the highly successful pediatric CF centers. Adult CF programs ensure lifelong CF specialty care.

Objective: To examine primary care pediatricians' (PCPs) beliefs about whether the family-centered medical home (FCMH) should be in primary or subspecialty care for children with different degrees of complexity; and to examine practice characteristics associated with these beliefs.

Methods: Data from the American Academy of Pediatrics Periodic Survey (PS 79) conducted in 2012 were analyzed. Outcomes were agreement/strong agreement that 1) primary care should be the FCMH locus for most children with special health care needs (CSHCN) and 2) subspecialty care is the best FCMH locus for children with rare or complex conditions.

Background: A major impediment to understanding quality of care for children with disabilities (CWD) is the lack of a method for identifying this group in claims databases. We developed the CWD algorithm (CWDA), which uses International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes to identify CWD.

Methods: We conducted a cross-sectional study that (1) ensured each of the 14,567 codes within the 2012 ICD-9-CM codebook was independently classified by 3 to 9 pediatricians based on the code's likelihood of indicating CWD and (2) triangulated the resulting CWDA against parent and physician assessment of children's disability status by using survey and chart abstraction, respectively.
