Hospital outbreak of methicillin-resistant Staphylococcus aureus caused by a new, possibly hyperepidemic variant from a previously sporadic strain.

Objective: To describe an ongoing outbreak that tripled the annual detection of methicillin-resistant Staphylococcus aureus (MRSA) carriage in a tertiary care hospital. Methods: Active surveillance of MRSA is performed since 20 years in our hospital. Our protocol includes screening of patients transferred from high-incidence health-care institutions or countries, roommates of new MRSA cases, and wards where _2 patients acquired MRSA during the same week. Contact precautions are used for known carriers. PFGE was used for molecular typing until 2004, and was then replaced by Double-Locus Sequence Typing (DLST). Results: A median yearly incidence of 173 new carriers of MRSA was observed from 2002 to 2007. Since September 2008, an increasing number of new cases were observed, mainly as successive clusters limited to distinct wards, reaching a total of 398 until October 2009. The yearly incidence of new cases rose to 275 in 2008 and 613 in 2009. 60% of the cases were due to one strain: DLST 4−4, ST 228, SCCmecI. The incidence of new cases due to the previously predominant strains remained unchanged. The epidemic strain corresponded to a new variant of a clone responsible for a previous outbreak in 2001, and only sporadically isolated (mean of 20 cases/year) since then. A case- control study documented a significant association between acquisition of the epidemic strain and a stay in intensive and intermediary care units, a highest number of internal transfers, but did not identify a point source of transmission. Infection control practices and antibiotic policy had remained unchanged for several years. Compliance with handhygiene as monitored yearly was on the rise. Screening of 313 healthcare workers only found one carrier of the epidemic strain lately in the outbreak. Additional infection control measures were enforced, including screening at ICU admission and discharge with PCR-based rapid test, routine screening for all patients leaving epidemic wards, introduction of PCR-based rapid test for contact tracing, additional working forces for environmental disinfection, and hospital-wide education of healthcare workers. However, the outbreak was still ongoing after 5 months. Conclusions: Factors linked to the dissemination of this new variant in our institution remain undetermined. This unresolved outbreak suggests that this new variant acquired hyperepidemic properties, which calls for further investigations.

The burden of hospital malnutrition in Spain: methods and development of the PREDyCES® study

It is well known that hospital malnutrition is a highly prevalent condition associated to increase morbidity and mortality as well as related healthcare costs. Although previous studies have already measured the prevalence and/or costs of hospital nutrition in our country, their local focus (at regional or even hospital level) make that the true prevalence and economic impact of hospital malnutrition for the National Health System remain unknown in Spain. The PREDyCES® (Prevalence of hospital malnutrition and associated costs in Spain) study was aimed to assess the prevalence of hospital malnutrition in Spain and to estimate related costs. Some aspects made this study unique: a) It was the first study in a representative sample of hospitals of Spain; b) different measures to assess hospital malnutrition (NRS2002, MNA as well as anthropometric and biochemical markers) where used both at admission and discharge and, c) the economic consequences of malnutrition where estimated using the perspective of the Spanish National Health System.

Standardizing admission and discharge processes to improve patient flow: A cross sectional study

Background: The aim of this study was to evaluate how hospital capacity was managed focusing on standardizing the admission and discharge processes. Methods: This study was set in a 900-bed university affiliated hospital of the National Health Service, near Barcelona (Spain). This is a cross-sectional study of a set of interventions which were gradually implemented between April and December 2008. Mainly, they were focused on standardizing the admission and discharge processes to improve patient flow. Primary administrative data was obtained from the 2007 and 2009 Hospital Database. Main outcome measures were median length of stay, percentage of planned discharges, number of surgery cancellations and median number of delayed emergency admissions at 8:00 am. For statistical bivariate analysis, we used a Chi-squared for linear trend for qualitative variables and a Wilcoxon signed ranks test and a Mann–Whitney test for non-normal continuous variables. Results: The median patients’ global length of stay was 8.56 days in 2007 and 7.93 days in 2009 (p<0.051). The percentage of patients admitted the same day as surgery increased from 64.87% in 2007 to 86.01% in 2009 (p<0.05). The number of cancelled interventions due to lack of beds was 216 patients in 2007 and 42 patients in 2009. The median number of planned discharges went from 43.05% in 2007 to 86.01% in 2009 (p<0.01). The median number of emergency patients waiting for an in-hospital bed at 8:00 am was 5 patients in 2007 and 3 patients in 2009 (p<0.01). Conclusions: In conclusion, standardization of admission and discharge processes are largely in our control. There is a significant opportunity to create important benefits for increasing bed capacity and hospital throughput.

Lack of extended venous thromboembolism prophylaxis in high-risk patients undergoing major orthopaedic or major cancer surgery. Electronic Assessment of VTE Prophylaxis in High-Risk Surgical Patients at Discharge from Swiss Hospitals (ESSENTIAL).

Extended pharmacological venous thromboembolism (VTE) prophylaxis beyond discharge is recommended for patients undergoing high-risk surgery. We prospectively investigated prophylaxis in 1,046 consecutive patients undergoing major orthopaedic (70%) or major cancer surgery (30%) in 14 Swiss hospitals. Appropriate in-hospital prophylaxis was used in 1,003 (96%) patients. At discharge, 638 (61%) patients received prescription for extended pharmacological prophylaxis: 564 (77%) after orthopaedic surgery, and 74 (23%) after cancer surgery (p < 0.001). Patients with knee replacement (94%), hip replacement (81%), major trauma (80%), and curative arthroscopy (73%) had the highest prescription rates for extended VTE prophylaxis; the lowest rates were found in patients undergoing major surgery for thoracic (7%), gastrointestinal (19%), and hepatobiliary (33%) cancer. The median duration of prescribed extended prophylaxis was longer in patients with orthopaedic surgery (32 days, interquartile range 14-40 days) than in patients with cancer surgery (23 days, interquartile range 11-30 days; p<0.001). Among the 278 patients with an extended prophylaxis order after hip replacement, knee replacement, or hip fracture surgery, 120 (43%) received a prescription for at least 35 days, and among the 74 patients with an extended prophylaxis order after major cancer surgery, 20 (27%) received a prescription for at least 28 days. In conclusion, approximately one quarter of the patients with major orthopaedic surgery and more than three quarters of the patients with major cancer surgery did not receive prescription for extended VTE prophylaxis. Future effort should focus on the improvement of extended VTE prophylaxis, particularly in patients undergoing major cancer surgery.

Energy deficit and length of hospital stay can be reduced by a two-step quality improvement of nutrition therapy: the intensive care unit dietitian can make the difference.

OBJECTIVE: Critically ill patients are at high risk of malnutrition. Insufficient nutritional support still remains a widespread problem despite guidelines. The aim of this study was to measure the clinical impact of a two-step interdisciplinary quality nutrition program. DESIGN: Prospective interventional study over three periods (A, baseline; B and C, intervention periods). SETTING: Mixed intensive care unit within a university hospital. PATIENTS: Five hundred seventy-two patients (age 59 ± 17 yrs) requiring >72 hrs of intensive care unit treatment. INTERVENTION: Two-step quality program: 1) bottom-up implementation of feeding guideline; and 2) additional presence of an intensive care unit dietitian. The nutrition protocol was based on the European guidelines. MEASUREMENTS AND MAIN RESULTS: Anthropometric data, intensive care unit severity scores, energy delivery, and cumulated energy balance (daily, day 7, and discharge), feeding route (enteral, parenteral, combined, none-oral), length of intensive care unit and hospital stay, and mortality were collected. Altogether 5800 intensive care unit days were analyzed. Patients in period A were healthier with lower Simplified Acute Physiologic Scale and proportion of "rapidly fatal" McCabe scores. Energy delivery and balance increased gradually: impact was particularly marked on cumulated energy deficit on day 7 which improved from -5870 kcal to -3950 kcal (p < .001). Feeding technique changed significantly with progressive increase of days with nutrition therapy (A: 59% days, B: 69%, C: 71%, p < .001), use of enteral nutrition increased from A to B (stable in C), and days on combined and parenteral nutrition increased progressively. Oral energy intakes were low (mean: 385 kcal*day, 6 kcal*kg*day ). Hospital mortality increased with severity of condition in periods B and C. CONCLUSION: A bottom-up protocol improved nutritional support. The presence of the intensive care unit dietitian provided significant additional progression, which were related to early introduction and route of feeding, and which achieved overall better early energy balance.

Évaluation d'une structure gériatrique entre l'ambulatoire et l'hospitalier [Geriatric institutions, between ambulatory and hospital care: patients' description and performance assessment].

Introduction : Décrire les patients d'une structure gériatrique offrant des hospitalisations de courte durée, dans un contexte ambulatoire, pour des situations gériatriques courantes dans le canton de Genève (Suisse). Mesurer les performances de cette structure en termes de qualité des soins et de coûts. Méthodes : Des données relatives au profil des 100 premiers patients ont été collectées (huit mois), ainsi qu'aux prestations, aux ressources et aux effets (réadmissions, décès, satisfaction, complications) de manière à mesurer différents indicateurs de qualité et de coûts. Les valeurs observées ont été systématiquement comparées aux valeurs attendues, calculées à partir du profil des patients. Résultats : Des critères d'admission ont été fixés pour exclure les situations dans lesquelles d'autres structures offrent des soins mieux adaptés. La spécificité de cette structure intermédiaire a été d'assurer une continuité des soins et d'organiser d'emblée le retour à domicile par des prestations de liaison ambulatoire. La faible occurrence des réadmissions potentiellement évitables, une bonne satisfaction des patients, l'absence de décès prématurés et le faible nombre de complications suggèrent que les soins médicaux et infirmiers ont été délivrés avec une bonne qualité. Le coût s'est révélé nettement plus économique que des séjours hospitaliers après ajustement pour la lourdeur des cas. Conclusion : L'expérience-pilote a démontré la faisabilité et l'utilité d'une unité d'hébergement et d'hospitalisation de court séjour en toute sécurité. Le suivi du patient par le médecin traitant assure une continuité des soins et évite la perte d'information lors des transitions ainsi que les examens non pertinents. INTRODUCTION: To describe patients admitted to a geriatric institution, providing short-term hospitalizations in the context of ambulatory care in the canton of Geneva. To measure the performances of this structure in terms of quality ofcare and costs. METHOD: Data related to the clinical,functioning and participation profiles of the first 100 patients were collected. Data related to effects (readmission, deaths, satisfaction, complications), services and resources were also documented over an 8-month period to measure various quality and costindicators. Observed values were systematically compared to expected values, adjusted for case mix. RESULTS: Explicit criteria were proposed to focus on the suitable patients, excluding situations in which other structures were considered to be more appropriate. The specificity of this intermediate structure was to immediately organize, upon discharge, outpatient services at home. The low rate of potentially avoidable readmissions, the high patient satisfaction scores, the absence of premature death and the low number of iatrogenic complications suggest that medical and nursing care delivered reflect a good quality of services. The cost was significantly lower than expected, after adjusting for case mix. CONCLUSION: The pilot experience showed that a short-stay hospitalization unit was feasible with acceptable security conditions. The attending physician's knowledge of the patients allowed this system tofocus on essential issues without proposing inappropriate services.

Association between frailty and delirium in older adult patients discharged from hospital.

BACKGROUND: Delirium and frailty - both potentially reversible geriatric syndromes - are seldom studied together, although they often occur jointly in older patients discharged from hospitals. This study aimed to explore the relationship between delirium and frailty in older adults discharged from hospitals. METHODS: Of the 221 patients aged >65 years, who were invited to participate, only 114 gave their consent to participate in this study. Delirium was assessed using the confusion assessment method, in which patients were classified dichotomously as delirious or nondelirious according to its algorithm. Frailty was assessed using the Edmonton Frailty Scale, which classifies patients dichotomously as frail or nonfrail. In addition to the sociodemographic characteristics, covariates such as scores from the Mini-Mental State Examination, Instrumental Activities of Daily Living scale, and Cumulative Illness Rating Scale for Geriatrics and details regarding polymedication were collected. A multidimensional linear regression model was used for analysis. RESULTS: Almost 20% of participants had delirium (n=22), and 76.3% were classified as frail (n=87); 31.5% of the variance in the delirium score was explained by frailty (R (2)=0.315). Age; polymedication; scores of the Confusion Assessment Method (CAM), instrumental activities of daily living, and Cumulative Illness Rating Scale for Geriatrics; and frailty increased the predictability of the variance of delirium by 32% to 64% (R (2)=0.64). CONCLUSION: Frailty is strongly related to delirium in older patients after discharge from the hospital.

Evaluation of outpatient discharge in patients with cutaneous melanoma

OBJECTIVE: to evaluate discharge in a group of patients with cutaneous melanoma according to recently established criteria. METHODS: we conducted an observational, cross-sectional study with 32 patients at the Hospital Universitário Clementino Fraga Filho (HUCFF) / Universidade Federal do Rio de Janeiro (UFRJ), between 1995 and 2013, in the following stages: IA (17 cases, 53.12%), IB (4 cases, 12.5%), IIA (3 cases, 9.37%), IIC (1 case, 3.12%), IIIB (1 case, 3.12%), IIIC (3 cases, 9.37%), melanomas in situ (2 cases, 6.25%), Tx (1 case, 3.12%). RESULTS: the follow-up time varied from one to 20 years (stage IA), five to 15 years (stage IB), six to 17 years (stage IIA), 20 years (stage IIC), 23 years (stage IIIB) and 14 to 18 years (stage IIIC). One melanoma in situ (subungueal) was discharged in the fourth year of follow-up and the other was promptly discharged. The Tx melanoma was followed for 12 years. We observed no relapses or recurrences in the period. CONCLUSION: although a controversial issue, it was possible to endorse the discharge of the patients since our follow-up time had already exceeded the one recommended by the other authors.

Diagnostic profile of inpatients as a determinant of length of stay in a general hospital psychiatric unit

The aim of this study was to determine if the diagnostic profile of inpatients of a psychiatric unit in a general hospital influences the length of stay. The results of a retrospective survey comprising the first 16 years of operation of the Psychiatric Unit of the Ribeirão Preto General Hospital (PURP) showed that the progressive increase observed in the length of stay correlated with the increase in percentage of schizophrenia diagnosis, after the 8th year of hospital operation, and of affective disorders, after the 12th year. The length of hospitalization kept increasing until the 16th year, even though there was no change in the diagnostic profile of the patients admitted to the unit. In a prospective study encompassing the next six months, 61 inpatients were evaluated with the Structured Clinical Interview for DSM-III-R and the Brief Psychiatric Rating Scale (BPRS). The results showed that 82% of the inpatients fulfilled the diagnostic criteria for the schizophrenic or affective disorder spectrum at admission, with a discharge rate slower than for other diagnoses, although the length of hospitalization did not significantly differ among diagnostic categories. The results further demonstrated that in every diagnostic category more than 50% of the patients stayed in hospital for more than one week after reaching a BPRS score equal to 6, indicative of discharge. Overall, these data suggest that the increase in length of hospitalization may be due to a higher percentage of patients with a diagnosis of schizophrenia and affective disorder admitted to the PURP. In addition, patients with low symptomatic levels remained in hospital longer than they should have.

Caracterización de los pacientes con hemorragia de vías digestivas altas no varicosa atendidos en el Hospital Universitario de la Samaritana, Cundinamarca

La hemorragia de vías digestivas altas (HVDA) es una emergencia frecuente. La etiología más común es la úlcera péptica. La restauración del volumen intravascular y la presión arterial son la prioridad del manejo. La endoscopia (EGD) debe realizarse luego de la reanimación inicial y lograda la estabilización hemodinámica, tratar la lesión subyacente mediante hemostasia. Se realiza un estudio en un hospital de referencia de tercer nivel, Cundinamarca, Colombia Materiales y métodos: Estudio descriptivo retrospectivo, datos obtenidos de la historia clínica electrónica de pacientes adultos que consultaron por urgencias en el Hospital Universitario de la Samaritana (HUS) por HVDA, diagnosticada por hematemesis, melenas, hematoquezia y/o anemia; a quienes se les realizó EGD durante abril del 2010 - abril del 2011. Resultados: Se atendieron 385 pacientes en el período de estudio, 100 fueron excluidos debido a hemorragia secundaria a várices esofágicas, historia incompleta y hemorragia digestiva baja, para un total de 285 pacientes analizados. El 69.1% eran mayores de 60 años. El 73.3% presentaba hipertensión arterial, el 55.1% reportaba ingesta de Anti-inflamatorios no esteroideos (AINES) y Aspirina (ASA). El 19.6% reportaba episodios de sangrado previos y 17.9% presentó inestabilidad hemodinámica. Sesenta y tres pacientes (22,1%) requirieron hemostasia endoscópica, treinta y dos (11.2%) presentaron resangrado. La mortalidad reportada fue del 13.1%, del cual 55.3% correspondía a hombres. Discusión: La mayoría de la población atendida en el HUS por HVDA son adultos mayores de 60 años. La úlcera péptica, continúa siendo el diagnóstico más frecuente asociado al uso de AINES y ASA.

Predictores de cambio en la función ventricular izquierda posterior a implante valvular aórtico transcateter comparado con reemplazo valvular aórtico quirúrgico en el hospital universitario fundación Cardioinfantil instituto de cardiología – Bogotá

Objetivos: Identificar predictores de recuperación de la función ventricular izquierda y comparar los hallazgos ecocardiográficos en pacientes con estenosis aórtica crítica sometidos a reemplazo quirúrgico de la válvula aórtica (RVA) o implantación de válvula aórtica transcatéter (TAVI). Métodos: Cuarenta y cuatro pacientes tratados con RVA se compararon con 34 pacientes con TAVI, los datos ecocardiográficos fueron retrospectivamente obtenidos antes de la intervención y previo al alta. Resultados: Se analizaron retrospectivamente pacientes tratados en la FCI - IC desde 2009 - 2015 (n = 78 pacientes, con una media de edad 70,29 ± 11,63, EuroSCORE logístico 3,75 (3-8,55) en RVA y 20,4 (15 , 47-23,32) en TAVI. Ambos grupos mostraron una disminución en los gradientes de la válvula aórtica, más en pacientes de TAVI, con un gradiente transaórtico pico (24,5 vs 18,5, p = 0,001) y medio (14 vs 10, p = 0,002) En comparación con RVA, TAVI presentó un mayor número de pacientes con insuficiencia aórtica paravalvular (47,1% frente a 2,3% p = 0.000). En total, el 61,5% presentó mejoría precoz de la función ventricular, el predictor en severo compromiso de la función del ventrículo izquierdo fue un alto índice de masa ventricular izquierda. Conclusiones: La implantación transcatéter de válvula aórtica es una alternativa al reemplazo quirúrgico de la válvula aórtica en pacientes con estenosis aórtica y alto riesgo quirúrgico. La recuperación postoperatoria precoz de la función ventricular izquierda en pacientes con severo compromiso de la función ventricular estuvo asociada a alto índice de masa ventricular izquierda.

Trauma craneoencefálico severo en la UCIP del Hospital de la Misericordia, 2010-2013

El Trauma Craneoencefálico (TCE) infantil constituye un motivo frecuente de consulta en Urgencias y supone la primera causa de muerte en niños, llegando a ser hasta del 50% en trauma severo. En Colombia se conocen cifras de TCE por algunos estudios descriptivos, pero no existen reportes en Bogotá ni específicamente en TCE severo. Objetivo: Caracterizar el trauma craneoencefálico severo pediátrico en la Unidad de Cuidado intensivo del Hospital de la Misericordia entre los años 2010 y 2013. Materiales y métodos: Un estudio descriptivo retrospectivo fue realizado en el Hospital de la Misericordia mediante revisión de las historias clínicas de los pacientes que ingresaron a la Unidad de Cuidado Intensivo pediátrico con diagnóstico de trauma craneoencefálico severo entre el año 2010 al 2013. Resultados: Se incluyeron 63 pacientes (71,4% hombres) con una edad mediana de 4 años (RIQ 2-8). La mayoría de los traumas fueron originados por caída o accidente de tránsito (79,4%). La principal lesión fue fractura de cráneo (79%). Casi la mitad de los pacientes sufrieron algún tipo de secuela neurológica al egreso (47,1%). La mayoría de los pacientes que murieron (19%) sufrieron choque hipovolémico (83,3%) y presentaron trauma asociado (66,7%). Conclusión: Las características y epidemiología del trauma craneoencefálico en nuestra población muestran claras similitudes con lo reportados en otras series de la literatura mundial y de Colombia, excepto por la mortalidad, que se esperaba más alta al estudiar solo pacientes con TCE severo.
