Engagement in measurement-based care (MBC) has been shown to be an effective practice for optimizing psychotherapy outcomes. Best practices for MBC suggest that it is crucial for therapists to consistently review scores. However, the exact impact of this practice on MBC's effectiveness has yet to be fully elucidated.

Boswell et al. (2022) professional practice guideline builds an excellent, evidence-driven argument in favor of the routine implementation of measurement-based care (MBC). Nonetheless, as learned from the attempted implementation of evidence-based psychotherapies, presenting empirical evidence does not affect therapist behavior.

Purpose: To characterize and examine the variability in receipt of inpatient (IP) physical therapy after lower extremity (LE) orthopedic surgery for individuals with cerebral palsy (CP) across hospital-level (region, bed size) and individual characteristics (gender, age, race/ethnicity, insurance type, technology dependency, and surgical burden).

Methods: We retrospectively analyzed physical therapy billing data of children with CP who had LE orthopedic surgery from October 1, 2015, through September 30, 2017, from the Pediatric Health Information Services (PHIS) database.

Results: Seventy-five percent of individuals received IP physical therapy during the hospital stay.

Background: Early Intervention (EI) is a federally mandated, state-administered system of care for children with developmental delays and disabilities under the age of three. Gaps exist in the process of accessing EI through pediatric primary care, and low rates of EI access are well documented and disproportionately affect poor and minority children. The aims of this paper are to examine child characteristics associated with gaps in EI (1) referral, (2) access and (3) service use.

Background: Family-centred care (FCC) is an approach to paediatric rehabilitation service delivery endorsing shared decision making and effective communication with families. There is great need to understand how early intervention (EI) programmes implement these processes, how EI caregivers perceive them, and how they relate to EI service use. Therefore, the purpose of this study is to examine (a) parent and provider perceptions about EI FCC processes and (b) the association between FCC perceptions and EI service intensity.

Objective: To estimate correlates of early intervention (EI) service dosage and gains in children's functional capabilities from EI entry and discharge.

Design: Retrospective cohort study.

Setting: Secondary analyses of a subset of data (N=1005) collected from an EI administrative database on children discharged from a large, urban EI program between October 1, 2014 and September 30, 2016.

Objective: Describe children's diagnostic, social, and functional characteristics associated with the use of core early intervention (EI) services.

Methods: The sample included infants and toddlers (N = 2045) discharged from an urban EI program (2014-2016). Adjusted logit models estimated the marginal effects and 95% confidence intervals (CIs) of receipt of any of the 4 core EI services, controlling for the child's developmental condition type, race and ethnicity, primary language, sex, insurance type, age at referral, and functional performance at EI entry.

Importance: Federal per-child early intervention (EI) appropriations have declined, while accountability for improving children's development and function has increased. It is critical to understand high-value EI services and systems.

Objective: To examine EI service timeliness and intensity, and the association between service intensity and outcomes.

Background: Electronic patient-reported outcomes (e-PROs) may provide valid and feasible options for obtaining family input on their child's functioning for care planning and outcome monitoring, but they have not been adopted into early intervention (EI). The purpose of this pilot study was to evaluate the feasibility of implementing technology-based functional assessment into EI practice and to examine child, family, service, and environmental correlates of caregiver-reported child functioning in the home.

Methods: In a cross-sectional design, eight individual EI providers participated in a 90-min technology-based functional assessment training to recruit participants and a 60-min semi-structured focus group post data collection.

Objective: To describe social disparities in early intervention (EI) service use and provider-reported outcomes.

Methods: Secondary data analysis of administrative data to ascertain EI service use of all EI and discipline-specific services and child and family characteristics. Adjusted logistic regression models estimated the odds of receiving each type of core EI service.

Study Purpose: To examine therapy use and spending for Medicaid-enrolled infants and toddlers with developmental conditions.

Methods: Sample infants and toddlers had a diagnosis (eg, cerebral palsy) or developmental delay (DD). Colorado Children's Medicaid administrative outpatient therapy claims (2006-2008) were used to estimate differences, by condition type and number of comorbid chronic conditions (CCCs), of any physical therapy (PT)/occupational therapy (OT) and Medicaid PT/OT spending.

Objective: To describe urban/rural differences in physical (PT) and occupational therapy (OT) service utilization and spending among a sample of young Medicaid-enrolled children with developmental conditions.

Methods: We analyzed Colorado Children's Medicaid administrative claims from 2006 to 2008. The sample included children who were younger than 36 months of age, had a select developmental condition, and were continuously eligible for each study year up to their third birthday.

Melanin protects the skin and eyes from the harmful effects of UV irradiation, protects neural cells from toxic insults, and is required for sound conduction in the inner ear. Aberrant regulation of melanogenesis underlies skin disorders (melasma and vitiligo), neurologic disorders (Parkinson's disease), auditory disorders (Waardenburg's syndrome), and opthalmologic disorders (age related macular degeneration). Much of the core synthetic machinery driving melanin production has been identified; however, the spectrum of gene products participating in melanogenesis in different physiological niches is poorly understood.
