Electronic consultations (eConsults): a proof of concept trial in Australia.

BACKGROUND: Electronic consultations (eConsults) allow general practitioners (GP) to seek the advice of a specialist via secure asynchronous digital communication. AIMS: To report the outcomes of a proof of concept (POC) trial of eConsults for patients with diabetes and endocrine disorders. METHODS: A prospective observational study conducted from November 2020 to May 2021. eConsults were provided by endocrinologists from the Princess Alexandra Hospital, Brisbane. The requests for advice were from GP in Brisbane South. An online questionnaire was completed by the GP and endocrinologist after each eConsult. RESULTS: Forty eConsults were performed over 7 months. The majority were in relation to type 2 diabetes (30%) or thyroid conditions (30%). All eConsult responses were performed within the target of 72 h with 92.5% responses provided within 24 h. The average time taken for the endocrinologist to perform the eConsult was 14.2 ± 4.4 min. The GP rated the value of eConsults as excellent 97% of the time. The eConsult resulted in a new or additional course of action 68% (19/28) of the time and confirmed a course of action 32% (9/28) of the time. The eConsult avoided the need for referral of the patient for a face-to-face specialist review in 55% of the eConsults. CONCLUSION: An eConsult service was able to be delivered by endocrinologists from a tertiary hospital to GP in Brisbane South. With an appropriate funding model, the broader implementation and adoption of eConsults has the potential to address specialist waiting lists and facilitate models of integrated care.

Reciprocal changes in DNA methylation and hydroxymethylation and a broad repressive epigenetic switch characterize FMR1 transcriptional silencing in fragile X syndrome.

BACKGROUND: Fragile X syndrome (FXS) is the most common form of inherited intellectual disability, resulting from the loss of function of the fragile X mental retardation 1 (FMR1) gene. The molecular pathways associated with FMR1 epigenetic silencing are still elusive, and their characterization may enhance the discovery of novel therapeutic targets as well as the development of novel clinical biomarkers for disease status. RESULTS: We have deployed customized epigenomic profiling assays to comprehensively map the FMR1 locus chromatin landscape in peripheral mononuclear blood cells (PBMCs) from eight FXS patients and in fibroblast cell lines derived from three FXS patient. Deoxyribonucleic acid (DNA) methylation (5-methylcytosine (5mC)) and hydroxymethylation (5-hydroxymethylcytosine (5hmC)) profiling using methylated DNA immunoprecipitation (MeDIP) combined with a custom FMR1 microarray identifies novel regions of DNA (hydroxy)methylation changes within the FMR1 gene body as well as in proximal flanking regions. At the region surrounding the FMR1 transcriptional start sites, increased levels of 5mC were associated to reciprocal changes in 5hmC, representing a novel molecular feature of FXS disease. Locus-specific validation of FMR1 5mC and 5hmC changes highlighted inter-individual differences that may account for the expected DNA methylation mosaicism observed at the FMR1 locus in FXS patients. Chromatin immunoprecipitation (ChIP) profiling of FMR1 histone modifications, together with 5mC/5hmC and gene expression analyses, support a functional relationship between 5hmC levels and FMR1 transcriptional activation and reveal cell-type specific differences in FMR1 epigenetic regulation. Furthermore, whilst 5mC FMR1 levels positively correlated with FXS disease severity (clinical scores of aberrant behavior), our data reveal for the first time an inverse correlation between 5hmC FMR1 levels and FXS disease severity. CONCLUSIONS: We identify novel, cell-type specific, regions of FMR1 epigenetic changes in FXS patient cells, providing new insights into the molecular mechanisms of FXS. We propose that the combined measurement of 5mC and 5hmC at selected regions of the FMR1 locus may significantly enhance FXS clinical diagnostics and patient stratification.

Design and implementation of an application and associated services to support interdisciplinary medication reconciliation efforts at an integrated healthcare delivery network.

Confusion about patients' medication regimens during the hospital admission and discharge process accounts for many preventable and serious medication errors. Many organizations have begun to redesign their clinical processes to address this patient safety concern. Partners HealthCare, an integrated delivery network in Boston, Massachusetts, has answered this interdisciplinary challenge by leveraging its multiple outpatient electronic medical records (EMR) and inpatient computerized provider order entry (CPOE) systems to facilitate the process of medication reconciliation. This manuscript describes the design of a novel application and the associated services that aggregate medication data from EMR and CPOE systems so that clinicians can efficiently generate an accurate pre-admission medication list. Information collected with the use of this application subsequently supports the writing of admission and discharge orders by physicians, performance of admission assessment by nurses, and reconciliation of inpatient orders by pharmacists. Results from early pilot testing suggest that this new medication reconciliation process is well accepted by clinicians and has significant potential to prevent medication errors during transitions of care.
