Does face-to-face pre-operative joint replacement education reduce hospital costs in a regional Australian hospital? A descriptive retrospective clinical audit

OBJECTIVE: To evaluate whether attending a face-to-face pre-operative joint replacement education in a regional setting reduces overall hospital costs and length of stay (LOS) following total knee replacement (TKR) or total hip replacement (THR). METHODS: A retrospective clinical audit reviewed the medical records of all patients who underwent an elective THR or TKR at Rockhampton Hospital in regional Queensland, Australia, between 03/2015 and 12/2016 (22 months). The pre-operative joint replacement education class was provided by a multidisciplinary team that included a physiotherapist, an occupational therapist, a dietician, a pharmacist and a social worker. In addition to demographic data, we extracted and analysed data related to total acute care and total healthcare cost, prevalence of post-operative complications, discharge destination and comorbidities (using the Functional Comorbidity Index). RESULTS: Out of 326 cases that were included in the analysis, 115 cases with TKR and 51 cases with THR attended a pre-operative education class. Demographic characteristics between those attending and not attending the class were largely similar, except from more females attending in the THR group. There was no difference in hospital costs or LOS between those who attended the class compared to those who did not for both the TKR and THR groups. Outcomes related to total acute stay costs, total cost including travel and education and score for Functional Comorbidities Index were similar between those who attended the class and those who did not. CONCLUSION: Pre-operative education does not reduce hospital costs (surgery and hospital stay) in Central Queensland

The Large-scale Structure of the Halo of the Andromeda Galaxy. II. Hierarchical Structure in the Pan-Andromeda Archaeological Survey

The Pan-Andromeda Archaeological Survey is a survey of >400 square degrees centered on the Andromeda (M31) and Triangulum (M33) galaxies that has provided the most extensive panorama of an L sstarf galaxy group to large projected galactocentric radii. Here, we collate and summarize the current status of our knowledge of the substructures in the stellar halo of M31, and discuss connections between these features. We estimate that the 13 most distinctive substructures were produced by at least 5 different accretion events, all in the last 3 or 4 Gyr. We suggest that a few of the substructures farthest from M31 may be shells from a single accretion event. We calculate the luminosities of some prominent substructures for which previous estimates were not available, and we estimate the stellar mass budget of the outer halo of M31. We revisit the problem of quantifying the properties of a highly structured data set; specifically, we use the OPTICS clustering algorithm to quantify the hierarchical structure of M31's stellar halo and identify three new faint structures. M31's halo, in projection, appears to be dominated by two "mega-structures," which can be considered as the two most significant branches of a merger tree produced by breaking M31's stellar halo into increasingly smaller structures based on the stellar spatial clustering. We conclude that OPTICS is a powerful algorithm that could be used in any astronomical application involving the hierarchical clustering of points.

SCOPE: SCUBA-2 Continuum Observations of Pre-protostellar Evolution - survey description and compact source catalogue

We present the first release of the data and compact-source catalogue for the JCMT Large Program SCUBA-2 Continuum Observations of Pre-protostellar Evolution (SCOPE). SCOPE consists of 850 μm continuum observations of 1235 Planck Galactic Cold Clumps (PGCCs) made with the Submillimetre Common-User Bolometer Array 2 on the James Clerk Maxwell Telescope. These data are at an angular resolution of 14.4 arcsec, significantly improving upon the 353 GHz resolution of Planck at 5 arcmin, and allowing for a catalogue of 3528 compact sources in 558 PGCCs. We find that the detected PGCCs have significant sub-structure, with 61 per cent of detected PGCCs having three or more compact sources, with filamentary structure also prevalent within the sample. A detection rate of 45 per cent is found across the survey, which is 95 per cent complete to Planck column densities of N(H2) > 5 × 10^21 cm^−2. By positionally associating the SCOPE compact sources with young stellar objects, the star formation efficiency, as measured by the ratio of luminosity to mass, in nearby clouds is found to be similar to that in the more distant Galactic Plane, with the column density distributions also indistinguishable from each other
