Implementation of a Standardized Approach to Improve the Pediatric Discharge Medication Process.

BACKGROUND AND OBJECTIVES: The pediatric inpatient discharge medication process is complicated, and caregivers have difficulty managing instructions. Authors of few studies evaluate systematic processes for ensuring quality in these care transitions. We aimed to improve caregiver medication management and understanding of discharge medications by standardizing the discharge medication process. METHODS: An interprofessional team at an urban, tertiary care children's hospital trialed interventions to improve caregiver medication management and understanding. These included mnemonics to aid in complete medication counseling, electronic medical record enhancements to standardize medication documentation and simplify dose rounding, and housestaff education. The primary outcome measure was the proportion of discharge medication-related failures in each 4-week period. Failure was defined as an incorrect response on ≥1 survey questions. Statistical process control was used to analyze improvement over time. Process measures related to medication documentation and dose rounding were compared by using the χ2 test and process control. RESULTS: Special cause variation occurred in the mean discharge medication-related failure rate, which decreased from 70.1% to 36.1% and was sustained. There were significantly more complete after-visit summaries (21.0% vs 85.1%; P < .001) and more patients with simplified dosing (75.2% vs 95.6%; P < .001) in the intervention period. Special cause variation also occurred for these measures. CONCLUSIONS: A systematic approach to standardizing the discharge medication process led to improved caregiver medication management and understanding after pediatric inpatient discharge. These changes could be adapted by other hospitals to enhance the quality of this care transition.

Caregiver Medication Management and Understanding After Pediatric Hospital Discharge.

OBJECTIVES: Caregivers frequently make mistakes when following instructions on discharge medications, and these instructions often contain discrepancies. Minimal literature reflects inpatient discharges. Our objective was to describe failures in caregiver management and understanding of inpatient discharge medications and to test the association of documentation discrepancies and sociodemographic factors with medication-related failures after an inpatient hospitalization. METHODS: This study took place in an urban tertiary care children's hospital that serves a low-income, minority population. English-speaking caregivers of children discharged on an oral prescription medication were surveyed about discharge medication knowledge 48 to 96 hours after discharge. The primary outcome was the proportion of caregivers who failed questions on a 10-item questionnaire (analyzed as individual question responses and as a composite outcome of any discharge medication-related failure). Bivariate tests were used to compare documentation errors, complex dosing, and sociodemographic factors to having any discharge medication-related failure. RESULTS: Of 157 caregivers surveyed, 70% had a discharge medication-related failure, most commonly because of lack of knowledge about side effects (52%), wrong duration (17%), and wrong start time (16%). Additionally, 80% of discharge instructions provided to caregivers lacked integral medication information, such as duration or when the next dose after discharge was due. Twenty five percent of prescriptions contained numerically complex doses. In bivariate testing, only race and/or ethnicity was significantly associated with having any failure (P = .03). CONCLUSIONS: The majority of caregivers had a medication-related failure after discharge, and most discharge instructions lacked key medication information. Future work to optimize the discharge process to support caregiver management and understanding of medications is needed.

Dynamic resolution of functionally related gene sets in response to acute heat stress.

BACKGROUND: Using a gene clustering strategy we determined intracellular pathway relationships within skeletal myotubes in response to an acute heat stress stimuli. Following heat shock, the transcriptome was analyzed by microarray in a temporal fashion to characterize the dynamic relationship of signaling pathways. RESULTS: Bioinformatics analyses exposed coordination of functionally-related gene sets, depicting mechanism-based responses to heat shock. Protein turnover-related pathways were significantly affected including protein folding, pre-mRNA processing, mRNA splicing, proteolysis and proteasome-related pathways. Many responses were transient, tending to normalize within 24 hours. CONCLUSION: In summary, we show that the transcriptional response to acute cell stress is largely transient and proteosome-centric.

Identification of novel pathway regulation during myogenic differentiation.

Stem cell differentiation is governed by extracellular signals that activate intracellular networks (or pathways) to drive phenotypic specification. Using a novel gene clustering strategy we determined pathway relationships from a genome-wide transcriptional dataset of skeletal myoblast differentiation. Established myogenic pathways, including cell contractility and cell-cycle arrest, were predicted with extreme statistical significance (p approximately 0). In addition, gene sets associated with angiogenesis, neuronal activity, and mRNA splicing were regulated, exposing developmental and therapeutic implications. Acquisition of transcriptional data spanning the entire differentiation time course provided context for a dynamic landscape of functional pathway regulation. This novel perspective on myogenic cell differentiation revealed previously unrecognized patterns of regulation. We predict that similar analyses will facilitate ongoing efforts to define molecular mechanisms in other stem cell and developmental paradigms. Finally, by combining an iterative process of analysis with supplementation of novel pathways, this application may evolve into a powerful discovery tool.

BRCA1 supports XIST RNA concentration on the inactive X chromosome.

BRCA1, a breast and ovarian tumor suppressor, colocalizes with markers of the inactive X chromosome (Xi) on Xi in female somatic cells and associates with XIST RNA, as detected by chromatin immunoprecipitation. Breast and ovarian carcinoma cells lacking BRCA1 show evidence of defects in Xi chromatin structure. Reconstitution of BRCA1-deficient cells with wt BRCA1 led to the appearance of focal XIST RNA staining without altering XIST abundance. Inhibiting BRCA1 synthesis in a suitable reporter line led to increased expression of an otherwise silenced Xi-located GFP transgene. These observations suggest that loss of BRCA1 in female cells may lead to Xi perturbation and destabilization of its silenced state.
