3D stacking and integration can provide system advantages equivalent to up to two technology nodes of scaling. This paper explores application drivers and computer aided design (CAD) for 3D ICs.

BackgroundRecent trends towards more cost-efficient and patient-centred treatment are converging to provide opportunities to improve the care of children. Observation units are hospital areas dedicated to the ongoing evaluation and management of patients for a brief period of time for well-defined conditions. We describe the implementation of a paediatric observation unit (POU) adjacent to a paediatric emergency department (PED) in an urban, academic, community hospital.MethodsStaffing models were designed to provide paediatric services to patients in both the PED and POU. Admission criteria, workflow and transfer guidelines were developed. Quality improvement initiatives were undertaken and evaluated. Unit throughput, patient outcomes and patient satisfaction data were collected and analysed.ResultsOver a 2-year period, there were 24 038 patient visits to the PED. Of these, 1215 (5.1%) patients required admission. Seven hundred and seventy-seven (64.0%) of these children were admitted to the POU. One hundred and nineteen (15.3%) of these patients were subsequently converted to inpatient hospitalisation. The average length of stay (LOS) was 25.7 hours in 2017 and 26.5 hours in 2018. Ten patients returned to the PED within 72 hours of discharge from the POU and four were readmitted. Patient satisfaction scores regarding ‘likelihood to recommend’ improved from the 36th to the 92nd percentile rank over a 1-year period. Close monitoring of patient outcomes allowed for the adjustment of admission guidelines, increased unit census and optimised utilisation.ConclusionA combined PED-POU has been successful at our institution in meeting benchmark goals set for LOS and conversion rates. In addition, quality improvement interventions increased patient census and improved patient satisfaction scores while reducing the inpatient burden on the referring children’s hospital.
