Delirium: guidelines for general hospitals.

OBJECTIVE: Delirium is highly prevalent in general hospitals but remains underrecognized and undertreated despite its association with increased morbidity, mortality, and health services utilization. To enhance its management, we developed guidelines covering all aspects, from risk factor identification to preventive, diagnostic, and therapeutic interventions in adult patients. METHODS: Guidelines, systematic reviews, randomized controlled trials (RCT), and cohort studies were systematically searched and evaluated. Based on a synthesis of retrieved high-quality documents, recommendation items were submitted to a multidisciplinary expert panel. Experts scored the appropriateness of recommendation items, using an evidence-based, explicit, multidisciplinary panel approach. Each recommendation was graded according to this process' results. RESULTS: Rated recommendations were mostly supported by a low level of evidence (1.3% RCT and systematic reviews, 14.3% nonrandomized trials vs. 84.4% observational studies or expert opinions). Nevertheless, 71.1% of recommendations were considered appropriate by the experts. Prevention of delirium and its nonpharmacological management should be fostered. Haloperidol remains the first-choice drug, whereas the role of atypical antipsychotics is still uncertain. CONCLUSIONS: While many topics addressed in these guidelines have not yet been adequately studied, an explicit panel and evidence-based approach allowed the proposal of comprehensive recommendations for the prevention and management of delirium in general hospitals.

Factors influencing adherence to standard precautions among nursing professionals in psychiatric hospitals

OBJECTIVE Evaluate and correlate individual, work-related and organizational factors that influence adherence to standard precautions among nursing professionals of psychiatric hospitals in São Paulo. METHOD An exploratory cross-sectional study conducted with 35 nursing professionals, using the assessment tool for adherence to standard precautions through the Likert scale, ranging from 1 to 5. RESULTS Knowledge of the precautions received a high score (4.69); adherence received (3.86) and obstacles (3.78), while intermediaries and the scales of organizational factors received low scores (2.61). There was a strong correlation between the magnitude adherence scale and the personal protective equipment availability (r = 0.643; p = 0.000). The training scale for prevention of HIV exposure (p = 0.007) was statistically different between the nurses and nursing assistants. CONCLUSION The organizational factors negatively contributed to adherence to standard precautions, indicating that psychiatric institutions lack safe working conditions, ongoing training and management actions to control infections.

The nurse in the management of materials in teaching hospitals

OBJECTIVETo present the nurse's integration within materials management of six teaching hospitals of Paraná - Brazil, and to describe the activities performed by nurses within this process.METHODA study of a qualitative approach and descriptive nature, conducted in teaching hospitals in Paraná, between June and August of 2013. The data collection was conducted through semi-structured interviews with eight nurses who worked in materials management; data were analyzed using content analysis.RESULTSThese showed that nurses perform ten categories of activities, distributed into four of the five steps of the materials management process.CONCLUSIONThe nurse, in performing of these activities, in addition to favoring the development of participative management, contributes to the organization, planning, and the standardization of the hospital supply process, giving greater credibility to the work with professionals who use the materials, and to the suppliers.

Finance versus costs for teaching hospitals in Spain

In this paper we analyse the observed systematic differences incosts for teaching hospitals (THhenceforth) in Spain. Concernhas been voiced regarding the existence of a bias in thefinancing of TH s has been raised once prospective budgets arein the arena for hospital finance, and claims for adjusting totake into account the legitimate extra costs of teaching onhospital expenditure are well grounded. We focus on theestimation of the impact of teaching status on average cost. Weused a version of a multiproduct hospital cost function takinginto account some relevant factors from which to derive theobserved differences. We assume that the relationship betweenthe explanatory and the dependent variables follows a flexibleform for each of the explanatory variables. We also model theunderlying covariance structure of the data. We assumed twoqualitatively different sources of variation: random effects andserial correlation. Random variation refers to both general levelvariation (through the random intercept) and the variationspecifically related to teaching status. We postulate that theimpact of the random effects is predominant over the impact ofthe serial correlation effects. The model is estimated byrestricted maximum likelihood. Our results show that costs are 9%higher (15% in the case of median costs) in teaching than innon-teaching hospitals. That is, teaching status legitimatelyexplains no more than half of the observed difference in actualcosts. The impact on costs of the teaching factor depends on thenumber of residents, with an increase of 51.11% per resident forhospitals with fewer than 204 residents (third quartile of thenumber of residents) and 41.84% for hospitals with more than 204residents. In addition, the estimated dispersion is higher amongteaching hospitals. As a result, due to the considerable observedheterogeneity, results should be interpreted with caution. From apolicy making point of view, we conclude that since a higherrelative burden for medical training is under public hospitalcommand, an explicit adjustment to the extra costs that theteaching factor imposes on hospital finance is needed, beforehospital competition for inpatient services takes place.

Characterization of a new clinical yeast species, Candida tunisiensis sp. nov., isolated from a strain collection from Tunisian hospitals.

From a collection of yeast isolates isolated from patients in Tunisian hospitals between September 2006 and July 2010, the yeast strain JEY63 (CBS 12513), isolated from a 50-year-old male that suffered from oral thrush, could not be identified to the species level using conventional methods used in clinical laboratories. These methods include matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), germ tube formation, and the use of CHROMagar Candida and metabolic galleries. Sequence analysis of the nuclear rRNA (18S rRNA, 5.8S rRNA, and 26S rRNA) and internal transcribed spacer regions (ITS1 and ITS2) indicated that the ribosomal DNA sequences of this species were not yet reported. Multiple gene phylogenic analyses suggested that this isolate clustered at the base of the Dipodascaceae (Saccharomycetales, Saccharomycetes, and Ascomycota). JEY63 was named Candida tunisiensis sp. nov. according to several phenotypic criteria and its geographical origin. C. tunisiensis was able to grow at 42°C and does not form chlamydospores and hyphae but could grow as yeast and pseudohyphal forms. C. tunisiensis exhibited most probably a haploid genome with an estimated size of 10 Mb on at least three chromosomes. Using European Committee for Antimicrobial Susceptibility Testing (EUCAST) and Clinical and Laboratory Standards Institute (CLSI) Candida albicans susceptibility breakpoints as a reference, C. tunisiensis was resistant to fluconazole (MIC = 8 μg/ml), voriconazole (MIC = 0.5 μg/ml), itraconazole (MIC = 16 μg/ml), and amphotericin B (MIC = 4 μg/ml) but still susceptible to posaconazole (MIC = 0.008 μg/ml) and caspofungin (MIC = 0.5 μg/ml). In conclusion, MALDI-TOF MS permitted the early selection of an unusual isolate, which was still unreported in molecular databases but could not be unambiguously classified based on phylogenetic approaches.

The ant fauna of hospitals: advancements in public health and research priorities in Brazil

Ants inhabit several types of natural and urban habitats, where they successfully nest. In urban environments, the hospitals should be considered priority for studies, as ants pose risks to human health due to their pathogen carrying potential. We aimed at surveying the literature about studies on ants in hospital settings in Brazil in the past 20 years. We found 40 papers in 22 journals, the first one published in 1993. Among them, 26 papers assessed pathogenic microorganisms on ants. We recorded 59 ant species, being Tapinoma melanocephalumthe most common. The Minas Gerais and São Paulo states had the largest number of published papers. Mato Grosso do Sul and Rio Grande do Sul showed the highest number of species. Exotic ant species were recorded in all states, except Goiás. Considering the potential to carry microorganisms and the importance of thorough studies on the ecology of ant species, our results can support and guide further research in Brazil.

Implications of diagnosis related groups (DRGs) for the management of hospitals.

Although tremendous advances have been made in the diagnosis and treatment of patients, hospital administrative systems have progressed relatively slowly. The types of information available to managers in industrial sectors are not available in the health sector. For this reason, many phenomena, such as the variations of average costs and lengths of stay between different hospitals, have remained poorly explained.The DRG system defines groups of patients that consume relatively homogeneous quantities of hospital resources. On the basis, it is possible to standardize average lengths of stay and average hospital costs in terms of the differences in case mix treated. Thus DRGs can serve as an explanation of variations in these factors between different hospitals, and also (but not only) for prospective reimbursement schems. As in a number of other European countries, a project has been set up in Switzerland to examine the possibilities of using DRGs in hospital management, planning and financing.

Educació en el lleure i l'ús de les tecnologies de la informació als hospitals pediàtrics: un estat de la qüestió

Estat de la qüestió sobre l'ús de les tecnologies de la informació als hospitals pediàtrics per tal d'educar en el lleure i pal·liar l'aïllament d'infants i adolescents i les seves famílies durant l'estada a l'hospital. A partir del grau d'implantació de les tecnologies, s'ha fet una anàlisi de diverses experiències d'arreu del món. S'han identificat dos models diferents pel que fa als objectius: els que centren la seva atenció en aspectes curriculars i els que potencien aspectes lúdics. Ambdós compten amb la implicació del personal sanitari vinculat als pacients i amb la figura del voluntari per a gestionar aquests serveis. Les principals diferències entre els projectes estudiats són les fonts de finançament, la tipologia de serveis que ofereixen i la naturalesa de les entitas que els promociona.

Les Biblioteques per a infants malalts als hospitals: a la recerca d'un espai propi

Les "Pautas para bibliotecas al servicio de pacientes de hospital, ancianos y discapacitados en centros de atención de larga duración" elaborades per l'IFLA són el marc normatiu de les biblioteques per a pacients. La seva existència, però, no garanteix el seu compliment; és per això que trobem realitats ben diverses, des dels hospitals que les reinterpreten i adeqüen a les seves necessitats i mitjans fins als que les ignoren o les desconeixen. En aquesta comunicació farem un recorregut per diverses alternatives o interpretacions als espais hospitalaris dedicats tant a l'oci com a la informació dels pacients en un context internacional. Es conclou que la biblioteca per a pacients és un servei en si mateix i es reivindica com un servei més al qual el malalt té dret.

Thirteen years of surgical site infection surveillance in Swiss hospitals

Contexte : Les infections du site opératoire (Surgical Site Infections - SSI) sont des complications fréquentes des procédures chirurgicales et un problème majeur de la santé publique. La surveillance constitue un élément essentiel de la prévention des SSI. Les résultats publiés récemment par certains pays européens suggèrent un impact positif qu'un réseau de surveillance active peut avoir sur le taux de SSI dans les hôpitaux participants. Objectif : La présente étude évalue les effets de la surveillance sur l'incidence des SSI en analysant les résultats du programme suisse multicentrique de surveillance des SSI. Méthodes : L'étude porte sur les 13 premières années du programme, regroupant au total 23 hôpitaux périphériques, cantonaux et universitaires de la Suisse occidentale et du sud. Ce programme, qui a intégré le consortium national Swissnoso en 2011, a été organisé conformément aux principes du système américain de National Nosocomial Infections Surveillance (NNIS). La surveillance incluait les procédures de la chirurgie viscérale (appendicectomie, cholécystectomie, chirurgie du colon et herniaire) et de l'orthopédie (arthroplastie de la hanche et du genou). Les données démographiques et cliniques étaient recueillies de manière standardisée par les infirmières cliniciennes en infectiologie pendant et après l'hospitalisation. Les rapports annuels, résumant les taux des SSI pour chaque type de procédure ainsi que la comparaison inter-hospitalière des risques relatifs ajustés à l'index NNIS, ont été discutés au sein de chaque établissement entre le comité des chirurgiens et le responsable local du programme. Analyses statistiques : Les taux cumulatifs des SSI ont été calculés pour chaque procédure chirurgicale. Une stratification selon le type de SSI (superficielle, profonde, organe/espace) et selon l'index NNIS a été respectée. Les facteurs de risque des SSI ont été identifiés pour chaque procédure par les analyses univariées des caractéristiques du patient (âge, sexe, score ASA, temps avant l'opération) et celles de l'opération (classe de contamination, durée de la chirurgie, urgence, antibioprophylaxie, laparoscopie, procédures multiples, ré¬intervention). Afin d'évaluer l'effet de la durée de la surveillance sur le taux des SSI, le temps de participation au programme a été calculé et stratifié par périodes d'un an par hôpital et par procédure. La corrélation entre la durée de la surveillance et les SSI a été estimée en utilisant les modèles de régression logistique pour chaque procédure avec l'ajustement pour les variables avec p ^ 0.2. Dans toutes les analyses, la valeur p < 0.05 était considéré significative. Résultats : Les taux globaux des SSI étaient : 18.2% pour les colectomies, 6.4% pour les appendicectomies, 2.3% pour les cholécystectomies, 1.7% pour les cures des hernies et 1.6% et 1.3% pour les arthroplasties de la hanche et du genou, respectivement. L'incidence des SSI post-hospitalières allait du 21% pour les colectomies au 94% pour les arthroplasties du genou. Concernant les facteurs prédictifs des SSI, l'index NNIS était valable seulement pour la chirurgie gastro-intestinale, la laparoscopie étant globalement protectrice mais associée à un taux d'infections profondes plus élevé après l'appendicectomie. La durée de la participation au programme de surveillance n'apportait pas de diminution des taux des SSI dans aucune procédure incluse dans l'étude. Conclusions : L'étude confirme l'impact de la surveillance post-hospitalière sur le taux des SSI, l'effet protectrice de la laparoscopie ainsi que l'absence de la valeur prédictive de l'index NNIS en orthopédie. Contrairement aux autres programmes européens nous n'avons pas détecté d'effet positif de la durée de la surveillance sur le taux des SSI. Les résultats obtenus ouvrent la discussion sur l'utilisation plus effective des données de surveillance des SSI.
