A multicenter study on the appropriateness of hospitalization in obstetric wards: application of Obstetric Appropriateness Evaluation Protocol (Obstetric AEP)

The cross-sectional study has been based on the implementation of the Obstetric Appropriateness Evaluation Protocol (OAEP) in seven hospitals to determine inappropriate hospital admissions and days of stay. The outcomes were: inappropriateness of admission and "percentage of inappropriateness" for one hospitalization. A total number of 2196 clinical records were reviewed. The mean percentage of inappropriateness for hospitalization was 22%. The percentage of inappropriateness for the first 10 d of hospitalization peaked in correspondence of the fourth (42%). The logistic regression model on inappropriated admission reported that emergency admission was a protective factor (OR = 0.4) and to be hospitalized in wards with 6530 beds risk factor (OR = 5.12). The second linear model on "percentage of inappropriateness" showed that inappropriated admission and wards with 6530 beds increased the percentage (p < 0.001); whereas the admission in Teaching Hospitals was inversely associated (p < 0.001). The present study suggests that the percentage of inappropriate admission depends especially on the inappropriate admission and the large number of beds in obstetric wards. This probably indicates that management of big hospitals, which is very complex, needs improving the processes of support and coordination of health professionals. The OAEP tool seems to be an useful instrument for the decision-makers to monitor and manage the obstetric wards. \ua9 2014 Informa UK Ltd. All rights reserved

Appropriateness of admission and days of stay in pediatric hospital in Ancona, Italy

Background: In Italy, hospital admission costs account for nearly 42% of total health expenditure; in the Marche region, this share exceeds 50%. High costs of hospitalization, however, can be partly explained by inappropriate use. The aim of this research was to assess the risk factors associated with inappropriate hospital admissions and stay for acute pediatric patients. Methods: Clinical records of children from 30 days to 14 years of age admitted to the wards of orthopedics, pediatrics, pediatric isolation, pediatric surgery and pediatric oncohematology at Salesi Pediatric Hospital of Ancona throughout 2004 were reviewed. The Italian Pediatric Appropriateness Evaluation Protocol (PRUO) was used as a tool for assessing inappropriateness of admission and days of stay. Results: Overall 21.7% (95% CI = 16.1%–22.4%) of hospital admissions and 30.3% (95% CI = 26.0%–34.9%) of days of stay were judged to be inappropriate. Multiple logistic regression analysis indicated that inappropriate admission was significantly associated with type of admission, discharge ward and place of residence. Inappropriateness of stay was significantly higher if admission was to a medical ward and if admission itself was judged inappropriate. Conclusions: In a socioeconomic context in which reducing waste is necessary, ineffective health care interventions are no longer tolerable. As a tool capable of integrating each patient’s specific features with those of the health care process, the pediatric PRUO could be a valid tool in the hands of managers for monitoring the appropriateness of admission and stay

Surface Deposition and Imaging of Large Ag Clusters Formed in He Droplets

The utility of a continuous beam of He droplets for the assembly and surface deposition of Ag clusters, ~ 300 - 6 000, is studied with transmission electron microscopy. Images of the clusters on amorphous carbon substrates obtained at short deposition times have provided for a measure of the size distribution of the metal clusters. The average sizes of the deposited clusters are in good agreement with an energy balance based estimate of Ag cluster growth in He droplets. Measurements of the deposition rate indicate that upon impact with the surface the He-embedded cluster is attached with high probability. The stability of the deposited clusters on the substrate is discussed.Comment: 24 pages, 5 figure

Applicazione delle anulazioni di cemento per la determinazione dell'et\ue0 di resti umani

Scopo di tale lavoro \ue8 verificare l'applicabilit\ue0, l'accuratezza e la precisione di tre differenti metodi per la valutazione dell'et\ue0 biologica: il conteggio delle anulazioni del cemento radicolare, il metodo di Lamendin e quello di Gustafson-Johanson. Per il metodo delle anulazioni del cemento sono stati utilizzati 194 denti decalcificati e non, colorati istologicamente mediante Ematossilina-Eosina, von Kossa e Tricromica di Masson; tale metodo risulta essere quello con il maggior coefficiente di correlazione ed ha inoltre restituito una maggiore precisione, mentre a suo sfavore gioca un tempo di preparazione dei campioni piuttosto lungo. Il metodo \ue8 stato testato anche su materile di natura archeologica. Sia il metodo di Lamendin che il Gustafson-Johanson, tendono a sovrastimare l'et\ue0 entro i 40 anni ed a sottostimarla al di sopra dei 40, ed entrambi i metodi si dimostrano pi\uf9 accurati in un range d'et\ue0 compreso tra i 35 ed i 45 anni, quello di Gustafson-Johanson \ue8 leggermente pi\uf9 preciso, mentre il Lamendin \ue8 certamente pi\uf9 semplice da applicare per i non esperti
