The 2011-12 pilot European Sentinel Registry of Transcatheter Aortic Valve Implantation: in-hospital results in 4,571 patients

AIMS The aim of this prospective multinational registry is to assess and identify predictors of in-hospital outcome and complications of contemporary TAVI practice. METHODS AND RESULTS The Transcatheter Valve Treatment Sentinel Pilot Registry is a prospective independent consecutive collection of individual patient data entered into a web-based case record form (CRF) or transferred from compatible national registries. A total of 4,571 patients underwent TAVI between January 2011 and May 2012 in 137 centres of 10 European countries. Average age was 81.4±7.1 years with equal representation of the two sexes. Logistic EuroSCORE (20.2±13.3), access site (femoral approach: 74.2%), type of anaesthesia and duration of hospital stay (9.3±8.1 days) showed wide variations among the participating countries. In-hospital mortality (7.4%), stroke (1.8%), myocardial infarction (0.9%), major vascular complications (3.1%) were similar in the SAPIEN XT and CoreValve (p=0.15). Mortality was lower in transfemoral (5.9%) than in transapical (12.8%) and other access routes (9.7%; p<0.01). Advanced age, high logistic EuroSCORE, pre-procedural ≥grade 2 mitral regurgitation and deployment failure predicted higher mortality at multivariate analysis. CONCLUSIONS Increased operator experience and the refinement of valve types and delivery catheters may explain the lower rate of mortality, stroke and vascular complications than in historical studies and registries.

A comparison of Markov and generalized linear models of hospital mortality

This paper reports a comparison of three modeling strategies for the analysis of hospital mortality in a sample of general medicine inpatients in a Department of Veterans Affairs medical center. Logistic regression, a Markov chain model, and longitudinal logistic regression were evaluated on predictive performance as measured by the c-index and on accuracy of expected numbers of deaths compared to observed. The logistic regression used patient information collected at admission; the Markov model was comprised of two absorbing states for discharge and death and three transient states reflecting increasing severity of illness as measured by laboratory data collected during the hospital stay; longitudinal regression employed Generalized Estimating Equations (GEE) to model covariance structure for the repeated binary outcome. Results showed that the logistic regression predicted hospital mortality as well as the alternative methods but was limited in scope of application. The Markov chain provides insights into how day to day changes of illness severity lead to discharge or death. The longitudinal logistic regression showed that increasing illness trajectory is associated with hospital mortality. The conclusion is reached that for standard applications in modeling hospital mortality, logistic regression is adequate, but for new challenges facing health services research today, alternative methods are equally predictive, practical, and can provide new insights. ^

Electrolyte disorders and in-hospital mortality during prolonged heat periods: a cross-sectional analysis

BACKGROUND Heat periods during recent years were associated with excess hospitalization and mortality rates, especially in the elderly. We intended to study whether prolonged warmth/heat periods are associated with an increased prevalence of disorders of serum sodium and potassium and an increased hospital mortality. METHODS In this cross-sectional analysis all patients admitted to the Department of Emergency Medicine of a large tertiary care facility between January 2009 and December 2010 with measurements of serum sodium were included. Demographic data along with detailed data on diuretic medication, length of hospital stay and hospital mortality were obtained for all patients. Data on daily temperatures (maximum, mean, minimum) and humidity were retrieved by Meteo Swiss. RESULTS A total of 22.239 patients were included in the study. 5 periods with a temperature exceeding 25 °C for 3 to 5 days were noticed and 2 periods with temperatures exceeding 25 °C for more than 5 days were noted. Additionally, 2 periods with 3 to 5 days with daily temperatures exceeding 30 °C were noted during the study period. We found a significantly increased prevalence of hyponatremia during heat periods. However, in the Cox regression analysis, prolonged heat was not associated with the prevalence of disorders of serum sodium or potassium. Admission during a heat period was an independent predictor for hospital mortality. CONCLUSIONS Although we found an increased prevalence of hyponatremia during heat periods, no convincing connection could be found for hypernatremia or disorders of serum potassium.

A practice-based culminating experience with Texas Children's Hospital: A hospital's journey to baby-friendly status

Breastfeeding and the use of human milk are widely accepted as the most complete form of nutrition for infants. Breastfeeding is shown to be associated with many positive health outcomes for both infants and mothers. Healthy People 2000 goals to increase breastfeeding rates in the early postpartum period to 75% fell short, with only 64% of mothers meeting this objective. Lack of support from healthcare providers, and unsupportive hospital policies and practices are noted as barriers to the initiation and duration of breastfeeding. The purpose of this study was to evaluate implementation of the BFHI Ten Steps to Successful Breastfeeding at Texas Children's Hospital. ^ The Baby-Friendly Hospital Initiative (BFHI) was developed in 1991 by the World Health Organization and the United Nations Children's Fund (UNICEF) to ensure that healthcare facilities offering maternity services adhere to the Ten Steps of Successful Breastfeeding and the International Code of Marketing of Breast-Milk Substitutes, and create legislation to protect the rights of breastfeeding women. The instrument used in this study was the BFHI 100 Assessment Tool created by Dr. Laura Haiek, Director of Public Health in Monteregie, Quebec, and her staff at Health and Social Services Agency of Quebec. The BFHI 100 tool utilizes 100 different indicators of compliance with BFHI through questionnaires administered to staff and administrators, pregnant and postpartum mothers, and an observer. ^ The study concluded that although there is much room for improvement in educating breastfeeding mothers, overall, the mothers interviewed were satisfied with their level of care in regards to breastfeeding support. Areas of improvement include staff training, as some nursing staff admitted to relying on the lactation consultants to provide most of the breastfeeding education for mothers. Only a small percentage of mothers interviewed reported that their baby “roomed-in” on average of 22 hours per day during their hospital stay. Staff encouragement of the rooming-in practice will help to increase the proportion of mothers who allow their babies to room-in. The current breastfeeding policy will also need to be revised and strengthened to be compliant with the Ten Steps. Ideally, Baby-Friendly practices will become the norm after staff are trained and policy revisions are made. Staff training and acceptance of breastfeeding as optimal nutrition for infants are the most critical factors that will ultimately drive change for the organization. ^

Variabilidad de la estancia media en pacientes hospitalizados en un hospital de Traumatología durante el año 2010

Objetivos: El objetivo principal del estudio es conocer la estancia media hospitalaria y su variabilidad en relación con el motivo de ingreso, en una unidad de hospitalización de un hospital monográfico de Traumatología. (Unión de Mutuas. Castellón) Metodología: Estudio transversal, descriptivo, basado en datos administrativos, cuya población estuvo formada por todos los individuos que tuvieron algún episodio de hospitalización durante el año 2010, siendo este el criterio de inclusión, por orden cronológico de aparición. Resultados: Se identificaron un total de 736 episodios asistenciales y 133 códigos CIE-9CM. La edad media fue 44 (+/-10) años. El 83,25% de los pacientes fueron varones. El código 836.0 (Desgarro de cartílago o menisco interno de la rodilla-actual) fue el diagnóstico más habitual (12,25%) y la artroscopia la técnica quirúrgica mayoritaria. “Fractura de pelvis” (CIE-9CM 808) resultó el código diagnóstico que presentó mayor estancia media con 25 (+/-9.84) estancias y mayor variabilidad de la misma, seguido de los diagnósticos “Fractura de diáfisis de tibia-cerrada”, “Fractura de diáfisis de tibia/peronéabierta”, “Contusión de múltiples sitios, ncoc” y “Fractura de tibia y peroné”. Conclusiones: Se observa poca variabilidad en la estancia media excepto en los procesos diagnosticados como fractura de pelvis y en los relacionados con fracturas de los miembros inferiores.

Hospital-based case-control study of bronchiectasis in indigenous children in central Australia

Background: Childhood pneumonia has been reported to be associated with the development of bronchiectasis but there are no case-control studies that have examined this. This study examined the relationship between hospital admission for episode(s) of pneumonia and the risk of radiologically proven bronchiectasis. Methods: A medical record-based case-control study of bronchiectasis in Indigenous children was conducted in Central Australia. Controls (183), matched to cases (61) by gender, age and year of diagnosis, were Indigenous children hospitalized with other conditions. Results: There was a strong association between a history of hospitalized pneumonia and bronchiectasis [odds ratio (OR), 15.2; 95% confidence interval (95% CI) 4.4-52.7]. This was particularly evident in recurrent hospitalized pneumonia (P for trend < 0.01), severe pneumonia episodes with longer hospital stay (P for trend < 0.01), presence of atelectasis (OR 11.9; 95% CI 3.1-45.9) and requirement for oxygen (P for trend < 0.01). The overall number of pneumonia episodes, rather than its site, was associated with bronchiectasis. Although the total number of pneumonia episodes in the first year of life did not increase the risk of bronchiectasis, more severe episodes early in life did. Malnutrition, premature birth and being small for gestational age were more common findings among cases. Breast-feeding appeared to be a protective factor (OR 0.2; 95% CI 0.1-0.7). Conclusions: Although we cannot fully answer the question of why bronchiectasis is much more common in Indigenous children, we have provided strong evidence of an association between bronchiectasis and severe and recurrent pneumonia episodes in infancy and childhood.

Successful recovery after major surgery: moving beyond length of stay.

There is strong evidence that Enhanced Recovery Pathways improve length of hospital stay, readmission rates, and complications after major surgery. However, recovery is a complex process that only finishes when the patient returns to normal function. Future studies should also address the patient experience, as well as functional recovery and quality of life after major surgery.

Clinical and functional outcomes of acute lower extremity compartment syndrome at a Major Trauma Hospital

Background: Acute lower extremity compartment syndrome (CS) is a condition that untreated causes irreversible nerve and muscle ischemia. Treatment by decompression fasciotomy without delay prevents permanent disability. The use of intracompartmental pressure (iCP) measurement in uncertain situations aids in diagnosis of severe leg pain. As an infrequent complication of lower extremity trauma, consequences of CS include chronic pain, nerve injury, and contractures. The purpose of this study was to observe the clinical and functional outcomes for patients with lower extremity CS after fasciotomy. Methods: Retrospective chart analysis for patients with a discharge diagnosis of CS was performed. Physical demographics, employment status, activity at time of injury, injury severity score, fracture types, pain scores, hours to fasciotomy, iCP, serum creatine kinase levels, wound treatment regimen, length of hospital stay, and discharge facility were collected. Lower extremity neurologic examination, pain scores, orthopedic complications, and employment status at 30 days and 12 months after discharge were noted. Results: One hundred twenty‑four patients were enrolled in this study. One hundred and eight patients were assessed at 12 months. Eighty‑one percent were male. Motorized vehicles caused 51% of injuries in males. Forty‑one percent of injuries were tibia fractures. Acute kidney injury occurred in 2.4%. Mean peak serum creatine kinase levels were 58,600 units/ml. Gauze dressing was used in 78.9% of nonfracture patients and negative pressure wound vacuum therapy in 78.2% of fracture patients. About 21.6% of patients with CS had prior surgery. Nearly 12.9% of patients required leg amputation. Around 81.8% of amputees were male. Sixty‑seven percent of amputees had associated vascular injuries. Foot numbness occurred in 20.5% of patients and drop foot palsy in 18.2%. Osteomyelitis developed in 10.2% of patients and fracture nonunion in 6.8%. About 14.7% of patients underwent further orthopedic surgery. At long‑term follow‑up, 10.2% of patients reported moderate lower extremity pain and 69.2% had returned to work. Conclusion: Escalation in leg pain and changes in sensation are the cardinal signs for CS rather than reliance on assessing for firm compartments and pressures. The severity of nerve injury worsens with the delay in performing fasciotomy. Standardized diagnostic protocols and wound treatment strategies will result in improved outcomes from this complication.

As infecções cervicais profundas constituem um verdadeiro desafio clínico, permanecendo na actualidade um problema relevante de saúde. Objectivo: Análise estatística dos internamentos com diagnóstico de celulite/abcesso cervical no Serviço de Otorrinolaringologia do Hospital Prof. Doutor Fernando Fonseca. Material e métodos: Avaliação de processos clínicos referentes a internamentos com o diagnóstico de entrada de celulite/ abcesso cervical, entre 2001-2011. Resultados: Neste período foram internados 80 doentes com média de idade de 44 anos. As infecções odontogénicas foram responsáveis por 83,3% das etiologias detectadas. O tempo médio de internamento foi de 8,72 dias. 94% dos doentes foram medicados com antibioterapia de acção dupla e em 22,5% recorreu-se à drenagem cervical. Conclusão: Ainda hoje as infecções cervicais profundas constituem casos de gravidade acrescida, com índice de mortalidade elevado. A infecção odontogénica constitui a sua principal etiologia. A instituição de antibioterapia endovenosa precoce e eventual drenagem cirúrgica são fundamentais no tratamento desta condição.

Increased hospital-based physical rehabilitation and information provision after intensive care unit discharge: the RECOVER randomized clinical trial.

Importance: critical illness results in disability and reduced health-related quality of life (HRQOL), but the optimum timing and components of rehabilitation are uncertain. Objective: to evaluate the effect of increasing physical and nutritional rehabilitation plus information delivered during the post–intensive care unit (ICU) acute hospital stay by dedicated rehabilitation assistants on subsequent mobility, HRQOL, and prevalent disabilities. Design, Setting, and Participants: a parallel group, randomized clinical trial with blinded outcome assessment at 2 hospitals in Edinburgh, Scotland, of 240 patients discharged from the ICU between December 1, 2010, and January 31, 2013, who required at least 48 hours of mechanical ventilation. Analysis for the primary outcome and other 3-month outcomes was performed between June and August 2013; for the 6- and 12-month outcomes and the health economic evaluation, between March and April 2014. Interventions: during the post-ICU hospital stay, both groups received physiotherapy and dietetic, occupational, and speech/language therapy, but patients in the intervention group received rehabilitation that typically increased the frequency of mobility and exercise therapies 2- to 3-fold, increased dietetic assessment and treatment, used individualized goal setting, and provided greater illness-specific information. Intervention group therapy was coordinated and delivered by a dedicated rehabilitation practitioner. Main Outcomes and Measures: the Rivermead Mobility Index (RMI) (range 0-15) at 3 months; higher scores indicate greater mobility. Secondary outcomes included HRQOL, psychological outcomes, self-reported symptoms, patient experience, and cost-effectiveness during a 12-month follow-up (completed in February 2014). Results: median RMI at randomization was 3 (interquartile range [IQR], 1-6) and at 3 months was 13 (IQR, 10-14) for the intervention and usual care groups (mean difference, −0.2 [95% CI, −1.3 to 0.9; P = .71]). The HRQOL scores were unchanged by the intervention (mean difference in the Physical Component Summary score, −0.1 [95% CI, −3.3 to 3.1; P = .96]; and in the Mental Component Summary score, 0.2 [95% CI, −3.4 to 3.8; P = .91]). No differences were found for self-reported symptoms of fatigue, pain, appetite, joint stiffness, or breathlessness. Levels of anxiety, depression, and posttraumatic stress were similar, as were hand grip strength and the timed Up & Go test. No differences were found at the 6- or 12-month follow-up for any outcome measures. However, patients in the intervention group reported greater satisfaction with physiotherapy, nutritional support, coordination of care, and information provision. Conclusions and Relevance: post-ICU hospital-based rehabilitation, including increased physical and nutritional therapy plus information provision, did not improve physical recovery or HRQOL, but improved patient satisfaction with many aspects of recovery.

Mean Platelet Volume (MPV), Platelet Distribution Width (PDW), Platelet Count and Plateletcrit (PCT) as predictors of in-hospital paediatric mortality: a case-control Study.

Background: Thrombocytopenia has been shown to predict mortality. We hypothesize that platelet indices may be more useful prognostic indicators. Our study subjects were children one month to 14 years old admitted to our hospital. Aim: To determine whether platelet count, plateletcrit (PCT), mean platelet volume (MPV) and platelet distribution width (PDW) and their ratios can predict mortality in hospitalised children. Methods: Children who died during hospital stay were the cases. Controls were age matched children admitted contemporaneously. The first blood sample after admission was used for analysis. Receiver operating characteristic (ROC) curve was used to identify the best threshold for measured variables and the ratios studied. Multiple regression analysis was done to identify independent predictors of mortality. Results: Forty cases and forty controls were studied. Platelet count, PCT and the ratios of MPV/Platelet count, MPV/PCT, PDW/Platelet count, PDW/PCT and MPV x PDW/Platelet count x PCT were significantly different among children who survived compared to those who died. On multiple regression analysis the ratio of MPV/PCT, PDW/Platelet count and MPV/ Platelet count were risk factors for mortality with an odds ratio of 4.31(95% CI, 1.69-10.99), 3.86 (95% CI, 1.53-9.75), 3.45 (95% CI, 1.38-8.64) respectively. In 67% of the patients who died MPV/PCT ratio was above 41.8 and PDW/Platelet count was above 3.86. In 65% of patients who died MPV/Platelet count was above 3.45. Conclusion: The MPV/PCT, PDW/Platelet count and MPV/Platelet count, in the first sample after admission in this case control study were predictors of mortality and could predict 65% to 67% of deaths accurately.

Objetivo: Analizar el manejo del trauma de tórax en el Hospital Vicente Corral Moscoso y describir las características demográficas de la población estudiada. Método: Estudio descriptivo retrospectivo, la muestra fue de 167 pacientes atendidos en el servicio de Emergencia del Hospital Vicente Corral Moscoso, con diagnóstico de trauma de tórax, durante el periodo enero de 2013 a junio de 2015; los datos se obtuvieron de las historias clínicas. Se analizaron las variables de datos demográficos y tratamiento, utilizando frecuencias, porcentajes y chi cuadrado. Se empleó el programa SPSS versión 18, Excel 2010. Resultados: La edad promedio fue de 37 años, con mayor frecuencia en varones con el 84.4%. Los diagnósticos fueron: hemotórax 36.53%, neumotórax 25.75%, hemoneumotórax 27.54%. El 4.8% de los pacientes recibió tratamiento no quirúrgico, el 82.6% avenamiento pleural; al 12.6% se practicó toracotomías al ingreso. Al 19.8% se realizó toracotomía durante la estancia hospitalaria debido a complicaciones como el hemotórax coagulado o residual. La mortalidad fue del 5.4% (9 pacientes), 7 presentaron lesiones extra torácicas. Conclusiones: El trauma de tórax se presentó en alto porcentaje en la tercera década de vida y se resolvió mayormente con avenamiento pleural. Las lesiones extra torácicas incrementan la mortalidad y necesitan un manejo multidisciplinario.

Impact on hip fracture mortality after the establishment of an orthogeriatric care program in a colombian hospital

El objetivo del estudio es evaluar la mortalidad a un año en pacientes con fractura de cadera, mayores de 65 años tratados en un programa establecido de orto-geriatría. 298 se trataron de acuerdo al protocolo de orto-geriatría, se calculo la mortalidad a un año, se establecieron los predictores de mortalidad orto-geriátrico. La sobrevida anual se incremento de 80% a 89% (p = .039) durante los cuatro años de seguimiento del programa y disminuyo el riesgo de mortalidad anual postoperatorio (Hazard Ratio = 0.54, p = .049). La enfermedad cardiaca y la edad maor a 85 años fueron predictores positivos para mortalidad.
