Management of Nursing Home Residents Following Acute Hospitalization: Efficacy of the “Regular Early Assessment Post-Discharge (REAP)” Intervention
Objectives: Rehospitalization of nursing home (NH) residents is frequent, costly, potentially avoidable and associated with diminished quality of life and poor survival. This study aims to evaluate the impact and cost-effectiveness of the Regular Early Assessment Post-Discharge (REAP) protocol of coordinated specialist geriatrician and nurse practitioner visits on rates of rehospitalization, hospital length of stay, and emergency department presentations for NH residents recently discharged from hospital. Design: Prospective randomized controlled study of recently hospitalized NH residents. Setting: Twenty-one of 24 eligible NHs within the geographical catchment area of St George Hospital, a 650-bed university hospital in Sydney, Australia. Participants: NH residents from eligible facilities admitted to St George Hospital's geriatric service were enrolled prior to hospital discharge. Intervention: REAP intervention of monthly coordinated specialist geriatrician and nurse practitioner assessments within participants' NHs for 6 months following hospital discharge. Measurements: Impact of the REAP intervention on hospital readmissions, hospital inpatient days, emergency department utilization, general practitioner visits, investigations and associated costs during the study intervention period. Results: Forty-three NH residents were randomly allocated to REAP intervention (n = 22) or control (n = 21) groups. The REAP intervention group had almost two-thirds fewer hospital readmissions (P =.03; Cohen's d = 0.73) and half as many emergency department visits than controls. Total costs were 50% lower in the REAP intervention group, with lower total hospital inpatient (P =.04; Cohen's d = 0.63) and total emergency department (P =.04; Cohen's d = 0.65) costs. Conclusion: Cost-effective reductions in the utilization of hospital-related services were demonstrated following implementation of the REAP intervention for NH residents recently discharged from hospital
Are Frontal Cognitive and Atrophy Patterns Different in PSP and bvFTD? A Comparative Neuropsychological and VBM Study
H1 haplotype of the MAPT gene is associated with lower regional gray matter volume in healthy carriers
The microtubule-associated protein Tau (MAPT) gene codes for the protein Tau that is involved in the pathogenesis of neurodegenerative diseases. Recent studies have detected an over-representation of the H1 haplotype of the MAPT gene in neurodegenerative disorders such as progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), frontotemporal dementia (FTD) and Parkinson's disease (PD), whereas the H2 haplotype has been found to be related to familial FTD. We aimed to investigate the association between MAPT haplotype status and brain morphology in healthy adults. A total of 150 healthy subjects underwent 3D high-resolution magnetic resonance (MR). MR images were processed following an optimized protocol to perform the Voxel-based morphometry (VBM) comparisons of the gray matter (GM) in H1 carriers (n=141) in contrast to H2H2 homozygous (n=9), and H1H1 homozygous (n=85) in contrast to H2 carriers (n=65). The threshold for statistical significance was 0.005 uncorrected. Opposite comparisons were also carried out. The groups had similar demographic and cognitive features. Compared with H2H2, the H1 carriers showed up to 19% smaller GM volume in the head of the right caudate nucleus, in the right middle frontal gyrus, in the left insula and orbito-frontal cortex, and in the inferior temporal and inferior cerebellar lobes, bilaterally. Compared with all H2 carriers, H1H1 displayed lower GM in the same regions, but the effect was smaller (5%), possibly due to a dilution effect by H1 in the H2 carriers group. The data suggest that H1 haplotype is associated with a particular cerebral morphology that may increase the susceptibility of the healthy carriers to develop neurodegenerative diseases such as sporadic tauopathies
