Format of medical order sheet improves security of antibiotics prescription: The experience of an intensive care unit.

OBJECTIVE: To assess whether formatting the medical order sheet has an effect on the accuracy and security of antibiotics prescription. DESIGN: Prospective assessment of antibiotics prescription over time, before and after the intervention, in comparison with a control ward. SETTING: The medical and surgical intensive care unit (ICU) of a university hospital. PATIENTS: All patients hospitalized in the medical or surgical ICU between February 1 and April 30, 1997, and July 1 and August 31, 2000, for whom antibiotics were prescribed. INTERVENTION: Formatting of the medical order sheet in the surgical ICU in 1998. MEASUREMENTS AND MAIN RESULTS: Compliance with the American Society of Hospital Pharmacists' criteria for prescription safety was measured. The proportion of safe orders increased in both units, but the increase was 4.6 times greater in the surgical ICU (66% vs. 74% in the medical ICU and 48% vs. 74% in the surgical ICU). For unsafe orders, the proportion of ambiguous orders decreased by half in the medical ICU (9% vs. 17%) and nearly disappeared in the surgical ICU (1% vs. 30%). The only missing criterion remaining in the surgical ICU was the drug dose unit, which could not be preformatted. The aim of antibiotics prescription (either prophylactic or therapeutic) was indicated only in 51% of the order sheets. CONCLUSIONS: Formatting of the order sheet markedly increased security of antibiotics prescription. These findings must be confirmed in other settings and with different drug classes. Formatting the medical order sheet decreases the potential for prescribing errors before full computerized prescription is available.

Pseudomonas aeruginosa: study of Antibiotic Resistance and Molecular Typing in Hospital Infection Cases in a Neonatal Intensive Care Unit from Rio de Janeiro City, Brazil

This study had the objective of to analyze the demographic and bacteriologic data of 32 hospitalized newborns in an neonatal intensive care unit of a public maternity hospital in Rio de Janeiro city, Brazil, seized by Pseudomonas aeruginosa sepsis during a period ranged from July 1997 to July 1999, and to determine the antimicrobial resistance percentage, serotypes and pulsed field gel electrophoresis (PFGE) patterns of 32 strains isolated during this period. The study group presented mean age of 12.5 days, with higher prevalence of hospital infection in males (59.4%) and vaginal delivery (81.2%), than females (40.6%) and cesarean delivery (18.8%), respectively. In this group, 20 (62.5%) patients received antimicrobials before positive blood cultures presentation. A total of 87.5% of the patients were premature, 62.5% presented very low birth weight and 40.6% had asphyxia. We detected high antimicrobial resistance percentage to b-lactams, chloramphenicol, trimethoprim/sulfamethoxazole and tetracycline among the isolated strains. All isolated strains were classified as multi-drug resistant. Most strains presented serotype O11 while PFGE analysis revealed seven distinct clones with isolation predominance of a single clone (75%) isolated from July 1997 to June 1998.

Model-based appraisal of minimum unit pricing for alcohol in Northern Ireland

In 2009, the Sheffield Alcohol Research Group (SARG) at Sheffield University developed the Sheffield Alcohol Policy Model version 2.0 (SAPM) to appraise the potential impact of alcohol policies, including different levels of MUP, for the population of England. In 2013, SARG were commissioned by the DHSSPS and the Department for Social Development to adapt the Sheffield Model to NI in order to appraise the potential impact of a range of alcohol pricing policies. The present report represents the results of this work. Estimates from the Northern Ireland (NI) adaptation of the Sheffield Alcohol Policy Model - version 3 - (SAPM3) suggest: 1. Minimum Unit Pricing (MUP) policies would be effective in reducing alcohol consumption, alcohol related harms (including alcohol-related deaths, hospitalisations, crimes and workplace absences) and the costs associated with those harms. 2. A ban on below-cost selling (implemented as a ban on selling alcohol for below the cost of duty plus the VAT payable on that duty) would have a negligible impact on alcohol consumption or related harms. 3. A ban on price-based promotions in the off-trade, either alone or in tandem with an MUP policy would be effective in reducing alcohol consumption, related harms and associated costs. 4. MUP and promotion ban policies would only have a small impact on moderate drinkers at all levels of income. Somewhat larger impacts would be experienced by increasing risk drinkers, with the most substantial effects being experienced by high risk drinkers. 5. MUP and promotion ban policies would have larger impacts on those in poverty, particularly high risk drinkers, than those not in poverty. However, those in poverty also experience larger relative gains in health and are estimated to marginally reduce their spending due to their reduced drinking under the majority of policies åÊ

The role of energy and nutritional support in the intensive care unit.

Malnutrition is common in critically ill, hospitalized patients and so represents a major problem for intensive care. Nutritional support can be beneficial in such cases and may help preserve vital organ and immune function. Energy requirements, route of delivery and potential complications of nutritional support are discussed in this paper.

Hepatitis B and C in the hemodialysis unit of Tocantins, Brazil: serological and molecular profiles

A survey was conducted in the hemodialysis population of the state of Tocantins, Brazil, aiming to assess the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, to analyze associated risk factors, and also to investigate these viruses genotypes distribution. During January and March 2001, all patients (n = 100) were interviewed at the unique dialysis unit in Tocantins. Blood samples were collected and serum samples were screened for HBV serological markers. Hepatitis B surface antigen positive samples were tested for HBV DNA. All samples were also tested for anti-HCV antibodies and HCV RNA. An overall prevalence of 45% was found for HBV infection (4% were HBsAg/anti-HBc positive, 2% were anti-HBc only and 39% had anti-HBc/anti-HBs markers). Concerning HCV infection, anti-HCV and HCV RNA were detected in 13% and 14% of the subjects, respectively. Three patients were HCV RNA positive and anti-HCV negative, resulting in an overall HCV prevalence of 16%. Univariate analysis of risk factors showed that only shift and length of time on hemodialysis were associated with HBV and HCV positivity, respectively. Among the four HBsAg-positive samples, HBV DNA was detected in three of them, which were identified as genotype A by restriction fragment length polymorphism (RFLP) analysis. All 14 HCV RNA-positive samples were genotyped by INNO-LiPA. Genotypes 1a and 3a were found in 85% and 15%, respectively. The present data show low HBsAg and HCV prevalence rates. The risk factors associated with HBV and HCV positivity suggest that nosocomial transmission may influence in spreading these viruses in the dialysis unit studied.

Les vertébroplasties: point de vue du rhumatologue [Vertebro-plasty: a rheumatologist's point of view]

Percutaneous vertebro-plasty is an efficient treatment of the symptomatic vertebral compression fracture refractory to optimal medical therapy. The procedure is used for neoplastic lesions, aggressive angioma, but also osteoporotic compression fractures. In order to adequately advice our patients, it is essential to know its indications and possible complications. However, to practice a vertebro-plasty for an osteoporotic compression fracture without any long term management of the osteoporotic disease is useless. Unfortunately, it still happens too often and it is essential that orthopedic surgeons, general practitioner, radiologist, rheumatologist, and any practitioners work together to guarantee the optimal management of our patients.

Application of control measures for infections caused by multi-resistant gram-negative bacteria in intensive care unit patients

Multi-resistant gram-negative rods are important pathogens in intensive care units (ICU), cause high rates of mortality, and need infection control measures to avoid spread to another patients. This study was undertaken prospectively with all of the patients hospitalized at ICU, Anesthesiology of the Hospital São Paulo, using the ICU component of the National Nosocomial Infection Surveillance System (NNIS) methodology, between March 1, 1997 and June 30, 1998. Hospital infections occurring during the first three months after the establishment of prevention and control measures (3/1/97 to 5/31/97) were compared to those of the last three months (3/1/98 to 5/31/98). In this period, 933 NNIS patients were studied, with 139 during the first period and 211 in the second period. The overall rates of infection by multi-resistant microorganisms in the first and second periods were, respectively, urinary tract infection: 3.28/1000 patients/day; 2.5/1000 patients/day; pneumonia: 2.10/1000 patients/day; 5.0/1000 patients/day; bloodstream infection: 1.09/1000 patients/day; 2.5/1000 patients/day. A comparison between overall infection rates of both periods (Wilcoxon test) showed no statistical significance (p = 0.067). The use of intervention measures effectively decreased the hospital bloodstream infection rate (p < 0.001), which shows that control measures in ICU can contribute to preventing hospital infections.

The expression of GABA receptors in the human auditory cortex

Abstract : GABA, the primary inhibitory neurotransmitter, and its receptors play an important role in modulating neuronal activity in the central nervous system and are implicated in many neurological disorders. In this study, GABAA and GABAB receptor subunit expression was visualized by immunohistochemistry in human auditory areas TC (= primary auditory area), TB, and TA. Both hemispheres from nine neurologically normal subjects and from four patients with subacute or chronic stroke were included. In normal brains, GABAA receptor subunit (α1, α2, & β2/3) labeling produced neuropil staining throughout all cortical layers as well as labeling fibers and neurons in layer VI for all auditory areas. Densitometry profiles displayed differences in GABAA subunit expression between primary and non-primary areas. In contrast to the neuropil labeling of GABAA subunits, GABAB1 and GABAB2 subunit immunoreactivity was revealed on neuronal somata and proximal dendritic shafts of pyramidal and non-pyramidal neurons in layers II-III, more strongly on supra- than in infragranular layers. No differences were observed between auditory areas. In stroke cases, we observed a downregulation of the GABAA receptor α2 subunit in granular and infragranular layers, while the other GABAA and the two GABAB receptor subunits remained unchanged. Our results demonstrate a strong presence of GABAA and GABAB receptors in the human auditory cortex, suggesting a crucial role of GABA in shaping auditory responses in the primary and non-primary auditory areas. The differential laminar and area expression of GABAA subunits that we have found in the auditory areas and which is partially different from that in other cortical areas speaks in favor of a fine turning of GABA-ergic transmission in these different compartments. In contrast, GABAB expression displayed laminar, but not areal differences; its basic pattern was also very similar to that of other cortical areas, suggesting a more uniform role within the cerebral cortex. In subacute and chronic stroke, the selective GABAA α2 subunit downregulation is likely to influence postlesional plasticity and susceptibility to medication. The absence of changes in the GABAB receptors suggests different regulation than in other pathological conditions, such as epilepsy, schizophrenia or bipolar disorder, in which a downregulation has been reported. Résumé : GABA, le principal neurotransmetteur inhibiteur, et ses récepteurs jouent un rôle important en tant que modulateur de l'activité neuronale dans le système nerveux central et sont impliqués dans de nombreux désordres neurologiques. Dans cette étude, l'expression des sous-unités des récepteur GABAA et GABAB a été visualisée par immunohistochimie dans les aires auditives du cortex humains: le TC (= aire auditif primaire), le TB, et le TA. Les deux hémisphères de neuf sujets considérés normaux du point de vue neurologique et de quatre patients ayant subis un accident cérébro-vasculaire et se trouvant dans la phase subaiguë ou chronique étaient inclues. Dans les cerveaux normaux, les immunohistochimies contre les sous-unités α1, α2, & β2/3 du récepteur GABAA ont marqué le neuropil dans toutes les couches corticales ainsi que les fibres et les neurones de la couche VI dans toutes les aires auditives. Le profile densitométrique montre des différences dans l'expression des sous-unités du récepteur GABAA entre les aires primaires et non-primaires. Contrairement au marquage de neuropil par les sous-unités du recepteur GABAA, 1'immunoréactivité des sous-unités GABAB1 et GABAB2 a été révélée sur les corps cellulaires neuronaux et les dendrites proximaux des neurones pyramidaux et non-pyramidaux dans les couches II-III et est plus dense dans les couches supragranulaires que dans les couches infragranulaires. Aucune différence n'a été observée entre les aires auditives. Dans des cas lésionnels, nous avons observé une diminution de la sous-unité α2 du récepteur GABAA dans les couches granulaires et infragranulaires, alors que le marquage des autres sous-unités du récepteur GABAA et des deux sous-unités de récepteur GABAB reste inchangé. Nos résultats démontrent une présence forte des récepteurs GABAA et GABAB dans le cortex auditif humain, suggérant un rôle crucial du neurotransmetteur GABA dans la formation de la réponse auditive dans les aires auditives primaires et non-primaires. L'expression différentielle des sous-unités de GABAA entre les couches corticales et entre les aires auditives et qui est partiellement différente de celle observée dans d'autres aires corticales préconise une modulation fine de la transmission GABA-ergic en ces différents compartiments. En revanche, l'expression de GABAB a montré des différences laminaires, mais non régionales ; son motif d'expression de base est également très semblable à celui d'autres aires corticales, suggérant un rôle plus uniforme dans le cortex cérébral. Dans les phases subaiguë et chronique des accidents cérébro-vasculaires, la diminution sélective de la sous-unité α2 du recepteur GABAA est susceptible d'influencer la plasticité et la susceptibilité postlésionnelle au médicament. L'absence de changement pour les récepteurs GABAB suggère que le récepteur est régulé différemment après un accident cerebro-vasculaire par rapport à d'autres conditions pathologiques, telles que l'épilepsie, la schizophrénie ou le désordre bipolaire, dans lesquels une diminution de ces sous-unités a été rapportée.
