ABSTRACT

BACKGROUND AND OBJECTIVES: Inequities in pediatric illness include unequal treatment and outcomes for children of historically marginalized races/ethnicities. Length of stay (LOS) is used to assess health care quality and is associated with higher costs/complications. Studies show LOS disparities for Black and Hispanic children in specific diagnoses, but it is unclear how broadly they exist or how they change over time. We examined the association between race/ethnicity and LOS longitudinally for the most common pediatric inpatient diagnoses. METHODS: We used the 2016 and 2019 Kids' Inpatient Databases. The 10 most frequent diagnoses in 2016 were determined. For each diagnosis in each year, we assessed the association between race and LOS by fitting a generalized linear mixed effects model with a negative binomial distribution, accounting for clustering and confounding. Using descriptive statistics, we compared associations between the 2 years for trends over time. RESULTS: Our analysis included >450 000 admissions and revealed significantly longer LOS for Black, Hispanic, and/or Asian American or Pacific Islander, Native American, and other children in 8 of the 10 diagnoses in 2016, with mixed changes over time. Three new disparities emerged in 2019. The largest disparities were for Black children in most diagnoses. CONCLUSIONS: Kids' Inpatient Database data showed longer LOS for children of historically marginalized race/ethnicity with common pediatric inpatient diagnoses, which largely persisted from 2016 to 2019. There is no plausible biological explanation for these findings, and inequities in social needs, access to care, and quality of care likely contribute. Future directions include further study to understand and address contributing factors.

ABSTRACT

OBJECTIVES: Social determinants of health have been demonstrated to be important drivers of health outcomes and disparities. Screening for social needs has been routinely performed and shown to be beneficial in ambulatory settings, but little is known regarding parent perspectives on screening during pediatric hospitalizations. This study sought to determine parental attitudes surrounding inpatient screening and screening process preferences in the hospital setting. METHODS: We conducted 17 semistructured interviews with English- and Spanish-speaking parents of hospitalized children at 1 tertiary and 2 community hospitals between July 2020 and February 2021, with questions probing opinions and experiences with social needs screening, comfort level with discussing social needs with hospital providers, and screening process preferences in the hospital setting. Interviews were recorded, professionally transcribed, and analyzed thematically. RESULTS: Participants were median age 32 years, with majority female and English-speaking, and nearly one-half with children admitted to a community hospital. Emergent themes included (1) importance of screening for social needs across multiple health care settings, (2) hospitals viewed as capable systems to respond to social needs, (3) most parents comfortable discussing social needs with inpatient providers, (4) appreciation for providers expressing caring and desire to help during inpatient screening, and (5) importance of a family-centered approach to inpatient screening. CONCLUSIONS: Parents reported positive perceptions regarding pediatric inpatient social needs screening importance and hospitals' ability to address social needs and identified multiple screening process preferences for the hospital setting that can inform the development of family-centered inpatient social needs screening strategies.

ABSTRACT

Phosphorylation is the most extensively studied posttranslational modification of proteins. There are approximately 500 kinases known in the human genome. The kinase-activated pathways regulate almost every aspect of cell function and a deregulated kinase cascade leads to impaired cellular function. Impaired regulation of several kinase cascades, including the epidermal growth factor receptor (EGFR) pathway, leading to tumor pathogenesis, is well documented. Thus, a phosphospecific test with prognostic or predictive value was expected in oncology. However, no phosphospecific IHC test is used in oncology clinics. Human topoisomerase I (topoI) inhibitors, camptothecin and its analogues (CPT), are used extensively to treat various solid tumors. Depending on tumor type, the response rate is only 13-32%. We have demonstrated that the deregulated kinase cascade is at the core of CPT resistance. DNA-PKcs, a kinase central to the DNA-double-strand break (DSB) response pathway, phosphorylates topoI at serine 10 (topoI-pS10), and cells with higher basal levels of topoI-pS10 degrade topoI rapidly and are resistant to this class of drug. The higher basal level of topoI phosphorylation is due to continual activation of DNA-PKcs, and one potential mechanism of this pathway activation is failure of upstream effector phosphatases such as phosphatase and tensin homolog (PTEN). Based on this understanding, we have developed an IHC-based test (P-topoIDx) that can stratify the responder and non-responder patient population.
