External validation of EPIC's Risk of Unplanned Readmission model, the LACE+ index and SQLape® as predictors of unplanned hospital readmissions: A monocentric, retrospective, diagnostic cohort study in Switzerland
<p>Introduction: Readmissions after an acute care hospitalization are relatively common, costly to the health care system, and are associated with significant burden for patients. As one way to reduce costs and simultaneously improve quality of care, hospital readmissions receive increasing interest from policy makers. It is only relatively recently that strategies were developed with the specific aim of reducing unplanned readmissions using prediction models to identify patients at risk. EPIC's Risk of Unplanned Readmission model promises superior performance. However, it has only been validated for the US setting. Therefore, the main objective of this study is to externally validate the EPIC's Risk of Unplanned Readmission model and to compare it to the internationally, widely used LACE+ index, and the SQLAPE® tool, a Swiss national quality of care indicator.</p> <p>Methods: A monocentric, retrospective, diagnostic cohort study was conducted. The study included inpatients, who were discharged between the 1<sup>st</sup> of January 2018 and the 31<sup>st</sup> of December 2019 from the Lucerne Cantonal Hospital, a tertiary-care provider in Central Switzerland. The study endpoint was an unplanned 30-day readmission. Models were replicated using the original intercept and beta coefficients as reported. Otherwise, score generator provided by the developers were used. For external validation, discrimination of the scores under investigation were assessed by calculating the area under the receiver operating characteristics curves (AUC). Calibration was assessed with the Hosmer-Lemeshow <i>X</i><sup><i>2</i></sup><span><span></span></span> goodness-of-fit test This report adheres to the TRIPOD statement for reporting of prediction models.</p> <p>Results: At least 23,116 records were included. For discrimination, the EPIC´s prediction model, the LACE+ index and the SQLape® had AUCs of 0.692 (95% CI 0.676-0.708), 0.703 (95% CI 0.687-0.719) and 0.705 (95% CI 0.690-0.720). The Hosmer-Lemeshow <i>X</i><sup><i>2</i></sup><span><span></span></span> tests had values of p<0.001.</p> <p>Conclusion: In summary, the EPIC´s model showed less favorable performance than its comparators. It may be assumed with caution that the EPIC´s model complexity has hampered its wide generalizability - model updating is warranted.</p>

Data from: Estimating bee abundance: Can mark-recapture methods validate common sampling protocols?
<p>Wild bees can be essential pollinators in natural, agricultural, and urban systems, but populations of some species have declined. Efforts to assess the status of wild bees are hindered by uncertainty in common sampling methods, such as pan traps and aerial netting, which may or may not provide a valid index of abundance across species and habitats. Mark-recapture methods are a common and effective means of estimating population size, widely used in vertebrates but rarely applied to bees. Here we review existing mark-recapture studies of wild bees and present a new case study comparing mark-recapture population estimates to pan trap and net capture for four taxa in a wild bee community. Net, but not trap, capture was correlated with abundance estimates across sites and taxa. Logistical limitations ensure that mark-recapture studies will not fully replace other bee sampling methods, but they do provide a feasible way to monitor selected species and measure the performance of other sampling methods.</p>

Data from: Validation and utilization of amended diagnostic criteria in Creutzfeldt-Jakob Disease surveillance
Objective: To validate an amended protocol for clinical diagnosis of sporadic Creutzfeldt-Jakob Disease (sCJD) including Real-Time Quaking-induced Conversion (RT-QuIC) and to observe its utilization in CJD surveillance. Methods: In the framework of a prospective epidemiological study, all neuropathological confirmed sCJD cases that received CSF RT-QuIC analysis during diagnostic work up (n=65) and a control group of non- CJD cases (n=118) were selected to investigate the accuracy of an amended diagnostic protocol. The patients had been referred to the German National Reference Center for Transmissible Spongiform Encephalopathies. The influence of the amended protocol on incidence figures was evaluated in the context of three years of surveillance activity (screened cases using 14-3-3 test: n=18.789, highly suspicious cases of CJD: n=704). Annual incidences were calculated using current criteria and the amended protocol. Results: The amended protocol showed a sensitivity of 97% and a specificity of 99%. When it was applied to all suspected cases that were referred to the reference center, the assessed incidence of CJD increased from 1.7 to 2.2 per million in 2016. Conclusion: CJD surveillance remains challenging as information from external healthcare institutions can be limited. RT-QuIC shows excellent diagnostic accuracy when applied in the clinical setting to symptomatic patients. Data for RT-QuIC alone, when applied as a general screening test, are not available yet. We propose an amended research protocol which improves early and accurate clinical diagnosis of sCJD during surveillance activities. The utilization of this protocol will probably lead to a significant increase of the incidence rate.
