Intensive care adult patients with severe respiratory failure caused by Influenza A (H1N1)v in Spain

Introduction: Patients with influenza A (H1N1)v infection have developed rapidly progressive lower respiratory tract disease resulting in respiratory failure. We describe the clinical and epidemiologic characteristics of the first 32 persons reported to be admitted to the intensive care unit (ICU) due to influenza A (H1N1)v infection in Spain. Methods: We used medical chart reviews to collect data on ICU adult patients reported in a standardized form. Influenza A (H1N1)v infection was confirmed in specimens using real-time reverse transcriptase-polymerase-chain-reaction (RT PCR) assay. Results: Illness onset of the 32 patients occurred between 23 June and 31 July, 2009. The median age was 36 years (IQR = 31 - 52). Ten (31.2%) were obese, 2 (6.3%) pregnant and 16 (50%) had pre-existing medical complications. Twenty-nine (90.6%) had primary viral pneumonitis, 2 (6.3%) exacerbation of structural respiratory disease and 1 (3.1%) secondary bacterial pneumonia. Twenty-four patients (75.0%) developed multiorgan dysfunction, 7 (21.9%) received renal replacement techniques and 24 (75.0%) required mechanical ventilation. Six patients died within 28 days, with two additional late deaths. Oseltamivir administration delay ranged from 2 to 8 days after illness onset, 31.2% received high-dose (300 mg/day), and treatment duration ranged from 5 to 10 days (mean 8.0 +/- 3.3). Conclusions: Over a 5-week period, influenza A (H1N1)v infection led to ICU admission in 32 adult patients, with frequently observed severe hypoxemia and a relatively high case-fatality rate. Clinicians should be aware of pulmonary complications of influenza A (H1N1)v infection, particularly in pregnant and young obese but previously healthy persons

Effectiveness of an intervention for improving drug prescription in primary care patients with multimorbidity and polypharmacy:Study protocol of a cluster randomized clinical trial (Multi-PAP project)

This study was funded by the Fondo de Investigaciones Sanitarias ISCIII (Grant Numbers PI15/00276, PI15/00572, PI15/00996), REDISSEC (Project Numbers RD12/0001/0012, RD16/0001/0005), and the European Regional Development Fund ("A way to build Europe").Background: Multimorbidity is associated with negative effects both on people's health and on healthcare systems. A key problem linked to multimorbidity is polypharmacy, which in turn is associated with increased risk of partly preventable adverse effects, including mortality. The Ariadne principles describe a model of care based on a thorough assessment of diseases, treatments (and potential interactions), clinical status, context and preferences of patients with multimorbidity, with the aim of prioritizing and sharing realistic treatment goals that guide an individualized management. The aim of this study is to evaluate the effectiveness of a complex intervention that implements the Ariadne principles in a population of young-old patients with multimorbidity and polypharmacy. The intervention seeks to improve the appropriateness of prescribing in primary care (PC), as measured by the medication appropriateness index (MAI) score at 6 and 12months, as compared with usual care. Methods/Design: Design:pragmatic cluster randomized clinical trial. Unit of randomization: family physician (FP). Unit of analysis: patient. Scope: PC health centres in three autonomous communities: Aragon, Madrid, and Andalusia (Spain). Population: patients aged 65-74years with multimorbidity (≥3 chronic diseases) and polypharmacy (≥5 drugs prescribed in ≥3months). Sample size: n=400 (200 per study arm). Intervention: complex intervention based on the implementation of the Ariadne principles with two components: (1) FP training and (2) FP-patient interview. Outcomes: MAI score, health services use, quality of life (Euroqol 5D-5L), pharmacotherapy and adherence to treatment (Morisky-Green, Haynes-Sackett), and clinical and socio-demographic variables. Statistical analysis: primary outcome is the difference in MAI score between T0 and T1 and corresponding 95% confidence interval. Adjustment for confounding factors will be performed by multilevel analysis. All analyses will be carried out in accordance with the intention-to-treat principle. Discussion: It is essential to provide evidence concerning interventions on PC patients with polypharmacy and multimorbidity, conducted in the context of routine clinical practice, and involving young-old patients with significant potential for preventing negative health outcomes.

Pandemic Influenza A in the ICU : Experience in Spain and Latin America GETGAG/SEMICYUC/(Spanish Work Group on Severe Pandemic Influenza A/SEMICYUC)

Introducción: La pandemia de gripe A(H1N1)v es la primera pandemia en la que las unidades de cuidados intensivos(UCI) desempeñan un papel fundamental. Su evolución ha sido muy rápida desde los primeros casos diagnosticados en México y la afectación posterior de países del cono sur hasta su llegada a Europa durante la época estival. Objetivo: Comparar las características clínicas y de evolución de los pacientes críticos ingresados hasta el 31 de julio de 2009 en España con algunas series de Latinoamérica. Material y método: Se consideraron 6 series de pacientes ingresados en la UCI. Se realizaron comparaciones de las características clínicas, complicaciones y evolución entre las series. Resultados: Los datos evidencian una población joven (35–45 años) con predominio de ingresos por neumonía viral con grave insuficiencia respiratoria y una elevada necesidad de ventilación mecánica (60–100%). Si bien algunas determinadas poblaciones, como los obesos, las embarazadas y los pacientes con enfermedad pulmonar crónica, parecen estar expuestas a un riesgo más elevado, la ausencia de comorbilidades alcanza un porcentaje considerable en casi todas las series (40–50%). La mortalidad superior en Latinoamérica osciló entre el 25 y el 50%, y demostró el particular potencial patogénico del nuevo virus. El uso del tratamiento antiviral es tardío (entre 3 y 6 días) y poco generalizado, con mayor retraso en Latinoamérica respecto de España. Conclusiones: Estos datos indican que una estrategia de tratamiento más intensivo con un acceso más precoz y fácil al antiviral podría reducir el número de pacientes que requieren UCI y su mortalidad.Abstract Introduction: Pandemic Influenza A (H1N1) v infection is the first pandemic in which intensive care units (ICU) play a fundamental role. It has spread very rapidly since the first cases were diagnosed in Mexico with the subsequent spread of the virus throughout the Southern Cone and Europe during the summer season. Objective: This study has aimed to compare the clinical presentation and outcome among the critical patients admitted to the ICU until July 31, 2009 in Spain with some series from Latin America. Material andmethod: Six series of critically ill patients admitted to the ICU were considered. Clinical characteristics, complications and outcome werecompared between series. Results: Young patients (35–45 years) with viral pneumonia as a predominant ICU admission cause with severe respiratory failure and a high need of mechanical ventilation (60–100%) were affected. Obesity, pregnancy and chronic lung disease were risk factors associated with a worse outcome, however there was a high number of patients without comorbidities (40–50%). Mortality rate was between 25–50% and higher in the Latin America series, demonstrating the specific potential pathogenesis of the new virus. The use of antiviral treatment was delayed (between 3 and 6 days) and not generalized, with greater delay in Latin America in regards to Spain. Conclusions: These data suggest that a more aggressive treatment strategy, with earlier and easier access to the antiviral treatment might reduce the number of ICU admissions and mortality

Prognostic Role of TAPSE to PASP Ratio in Patients Undergoing MitraClip Procedure.

Transcatheter mitral valve repair (TMVR) is an effective therapy for high-risk patients with severe mitral regurgitation (MR) but heart failure (HF) readmissions and death remain substantial on mid-term follow-up. Recently, right ventricular (RV) to pulmonary arterial (PA) coupling has emerged as a relevant prognostic predictor in HF. In this study, we aimed to assess the prognostic value of tricuspid annular plane systolic excursion (TAPSE) to PA systolic pressure (PASP) ratio as a non-invasive measure of RV-to-PA coupling in patients undergoing TMVR with MitraClip (Abbott, CA, USA). Multicentre registry including 228 consecutive patients that underwent successful TMVR with MitraClip. The sample was divided in two groups according to TAPSE/PASP median value: 0.35. The primary combined endpoint encompassed HF readmissions and all-cause mortality. Mean age was 72.5 ± 11.5 years and 154 (67.5%) patients were male. HF readmissions and all-cause mortality were more frequent in patients with TAPSE/PASP ≤ 0.35: Log-Rank 8.844, p = 0.003. On Cox regression, TAPSE/PASP emerged as a prognostic predictor of the primary combined endpoint, together with STS-Score. TAPSE/PASP was a better prognostic predictor than either TAPSE or PASP separately. TAPSE/PASP ratio appears as a novel prognostic predictor in patients undergoing MitraClip implantation that might improve risk stratification and candidate selection
