Differences in compliance with Surviving Sepsis Campaign recommendations according to hospital entrance time: day versus night

Introduction Higher compliance with Surviving Sepsis Campaign (SSC) recommendations has been associated with lower mortality. The authors evaluate differences in compliance with SSC 6-hour bundle according to hospital entrance time (day versus night) and its impact on hospital mortality. Methods Prospective cohort study of all patients with community-acquired severe sepsis admitted to the intensive care unit of a large university tertiary care hospital, over 3.5 years with a follow-up until hospital discharge. Time to compliance with each recommendation of the SSC 6-hour bundle was calculated according to hospital entrance period: day (08:30 to 20:30) versus night (20:30 to 08:30). For the same periods, clinical staff composition and the number of patients attending the emergency department (ED) was also recorded. Results In this period 300 consecutive patients were included. Compliance rate was (night vs. day): serum lactate measurement 57% vs. 49% (P = 0.171), blood cultures drawn 59% vs. 37% (P 8 mmHg 45% vs. 29% (P = 0.021), and central venous oxygen saturation (SvcO2) >70%, 7% vs. 2% (P = 0.082); fluids were administered in all patients with hypotension in both periods and vasopressors were administered in patients with hypotension not responsive to fluids in 100% vs. 99%. Time to get specific actions done was also different (night vs. day): serum lactate measurement (4.5 vs. 7 h, P = 0.018), blood cultures drawn (4 vs. 8 h, P < 0.001), antibiotic administration (5 vs. 8 h, P < 0.001), central venous pressure (8 vs. 11 h, P = 0.01), and SvcO2 monitoring (2.5 vs. 11 h, P = 0.222). The composition of the nursing team was the same around the clock; the medical team was reduced at night with a higher proportion of less differentiated doctors. The number of patients attending the Emergency Department was lower overnight. Hospital mortality rate was 34% in patients entering in the night period vs. 40% in those entering during the day (P = 0.281). Conclusion Compliance with SSC recommendations was higher at night. A possible explanation might be the increased nurse to patient ratio in that period. Adjustment of the clinical team composition to the patients' demand is needed to increase compliance and improve prognosis

The impact of healthcare-associated infection on mortality: failure in clinical recognition is related with inadequate antibiotic therapy

Purpose To understand if clinicians can tell apart patients with healthcare-associated infections (HCAI) from those with community-acquired infections (CAI) and to determine the impact of HCAI in the adequacy of initial antibiotic therapy and hospital mortality. Methods One-year prospective cohort study including all consecutive infected patients admitted to a large university tertiary care hospital. Results A total of 1035 patients were included in this study. There were 718 patients admitted from the community: 225 (31%) with HCAI and 493 (69%) with CAI. Total microbiologic documentation rate of infection was 68% (n = 703): 56% in CAI, 73% in HCAI and 83% in hospital-acquired infections (HAI). Antibiotic therapy was inadequate in 27% of patients with HCAI vs. 14% of patients with CAI (p<0.001). Among patients with HCAI, 47% received antibiotic therapy in accordance with international recommendations for treatment of CAI. Antibiotic therapy was inadequate in 36% of patients with HCAI whose treatment followed international recommendations for CAI vs. 19% in the group of HCAI patients whose treatment did not follow these guidelines (p = 0.014). Variables independently associated with inadequate antibiotic therapy were: decreased functional capacity (adjusted OR = 2.24), HCAI (adjusted OR = 2.09) and HAI (adjusted OR = 2.24). Variables independently associated with higher hospital mortality were: age (adjusted OR = 1.05, per year), severe sepsis (adjusted OR = 1.92), septic shock (adjusted OR = 8.13) and inadequate antibiotic therapy (adjusted OR = 1.99). Conclusions HCAI was associated with an increased rate of inadequate antibiotic therapy but not with a significant increase in hospital mortality. Clinicians need to be aware of healthcare-associated infections among the group of infected patients arriving from the community since the existing guidelines regarding antibiotic therapy do not apply to this group and they will otherwise receive inadequate antibiotic therapy which will have a negative impact on hospital outcome.Funding: Supported by an unrestricted grant from ASSUCIP (Associação de Apoio à Unidade de Cuidados Intensivos Polivalente, Hospital de Santo António, Porto, Portugal).

The Role of Noninvasive Ventilation in Patients with "Do Not Intubate" Order in the Emergency Setting

Noninvasive ventilation (NIV) is being used increasingly in patients who have a "do not intubate" (DNI) order. However, the impact of NIV on the clinical and health-related quality of life (HRQOL) in the emergency setting is not known, nor is its effectiveness for relieving symptoms in end-of-life care. OBJECTIVE: The aim of this prospective study was to determine the outcome and HRQOL impact of regular use of NIV outcomes on patients with a DNI order who were admitted to the emergency room department (ED). METHODS: Eligible for participation were DNI-status patients who receive NIV for acute or acute-on-chronic respiratory failure when admitted to the ED of a tertiary care, university-affiliated, 600-bed hospital between January 2014 and December 2014. Patients were divided into 2 groups: (1) those whose DNI order related to a decision to withhold therapy and (2) those for whom any treatment, including NIV, was provided for symptom relief only. HRQOL was evaluated only in group 1, using the 12-item Short Form Health Survey (SF-12). Long-term outcome was evaluated 90 days after hospital discharge by means of a telephone interview. RESULTS: During the study period 1727 patients were admitted to the ED, 243 were submitted to NIV and 70 (29%) were included in the study. Twenty-nine (41%) of the 70 enrollees received NIV for symptom relief only (group2). Active cancer [7% vs 35%, p = 0,004] and neuromuscular diseases [0% vs. 17%] were more prevalent in this group. NIV was stopped in 59% of the patients in group 2 due to lake of clinical benefit. The in-hospital mortality rate was 37% for group 1 and 86% for group 2 0,001). Among patients who were discharged from hospital, 23% of the group 1 and all patients in group 2 died within 90 days. Relative to baseline, no significant decline in HRQOL occurred in group 1 by 90 days postdischarge. CONCLUSION: The survival rate was 49% among DNI-status patients for whom NIV was used as a treatment in ED, and these patients did not experience a decline in HRQOL throughout the study. NIV did not provide significant relief of symptoms in more than half the patients who receive it for that purpose.Supported, in part, by grants from the Discipline of Initiation to Clinical Investigation (Disciplina de Iniciação à Investigação Clínica) of Instituto de Ciências Biomédicas Abel Salazar and in part by ASSUCIP (Associação dos Amigos da Unidade de Cuidados Intensivos Polivalente, Hospital de Santo António, Porto, Portugal).info:eu-repo/semantics/publishedVersio

Deliriumin the ICU setting ‐ a subjective and theoretical survey before the implementation of the Confusion Assessment Method for the ICU in an unit

Background and Goal of Study: The current definition of delirium comprises acute change or fluctuation in mental status and inattention, accompanied by either altered level of consciousness or disorganized thinking. It is a frequent condition in the ICU and it is associated with longer hospital stay, increase in mortality at 6 months and long-term cognitive impairment, but remains under diagnosed. The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) has been validated and implemented in many ICUs and its use is recommended by the Society of Critical Care Medicine. It is our purpose to evaluate the individual perspective and the objective knowledge of our staf f about delirium before the implementation of the CAM-ICU. Materials and Methods: Anonymous survey to our ICU clinical staf f which contained subjective and ‘true or false’ questions. Data was analised with the sof tware SPSS version 17.0. The Wilcoxon test was used to compare autoperception of knowledge about delirium and the content of answers regarding its definiton. Results: Forty two questionnaires were returned (participation rate of 73%), 11 from physicians and 31 from nurses. Overall, 61,9% of inquiries think they can give a definition for delirium in the ICU and 50% claim to be able to evaluate delirium. 28,6% of the respondents - 63,6% of the physicians and 16,1% of the nurses - know the CAM-ICU. From these only a quarter has received education on this method, 75% think it’s easy to apply and 66% don’t see its use as an increase in the daily workload. We found a high rate of wrong and ‘I don’t know’ answers to questions about operationalization, diagnosis and outcome. The subjects’ auto-perception on their knowledge about delirium [Likert scale] was compared to their ability to answer questions related to its definiton - ‘attention deficit is essencial for diagnosis’ [true], Wilcoxon test Z=-4,699 (p< 0,001); ‘disorganized thinking is essential for diagnosis’ [false], Wilcoxon test Z=-4,437 (p< 0,001). Conclusions: The respondents’ auto perception of knowledge about delirium doesn’t translate in the ability of giving an appropriate definition and making an adequate evaluation. Most of the inquiries don’t know the CAM-ICU, but those who do believe it’s easy to apply and its use won’t increase the workload. We performed educational sessions about delirium and the CAM-ICU in our unit to encourage our clinical staf f to deal properly with this hazardous condition

Efeito inicial da capoeira melhorada no número de esporos de fungos micorrízicos arbusculares.

O aumento da frequência do corte e queima da vegetação secundária e a redução do tempo de pousio tem levado a perda da capacidade produtiva dos solos agrícolas, principalmente no Nordeste Paraense. Alternativas que recuperem a produtividade agrícola em áreas alteradas e abandonadas tem sido objeto de estudo de muitas pesquisas. O objetivo deste estudo foi avaliar o efeito inicial do pousio melhorado no número de esporos de fungos micorrízicos arbusculares, em propriedade de agricultor familiar em Igarapé-Açu. O delineamento experimental utilizado foi inteiramente ao acaso, com quatro repetições. Os tratamentos consistiram em diferentes pousios compostos por plantios puros de acácia, guandu, ingá e titônia, adubados ou não com fosfato de rocha, como referência teve-se o crescimento da regeneração natural. Após seis meses da instalação do experimento, identificou-se que o tratamento titônia com aplicação de fosfato de rocha foi o que mais contribuiu para o aumento do número de esporos, e o que menos contribuiu foi o ingá sem fosfato de rocha

Ventilação Não-Invasiva no Edema Agudo do Pulmão no Serviço de Urgência

Abstract Bilevel positive pressure (BiPAP) non-invasive ventilation (NIV) is frequently used in our emergency department (ED), as an adjuvant in the treatment of acute cardiogenic pulmonary edema (ACPE) to reduce the need for tracheal intubation (TI) in these patients. The purpose of our study was to evaluate the safety of NIV in patients with ACPE in our ED, used by a group of physicians outside the intensive care unit (ICU), by comparing our results with previously published results. We also wanted to identify possible additional advantages of NIV in the treatment of acpe. We recorded clinical and physiological data before and after NIV of all patients with diagnosis and treatment of ACPE in our ED and for whom NIV was ordered as adjuvant treatment, between July 2004 and February 28 2005. During this period, NIV was ordered in 17 patients with ACPE. The mean ventilation pressures used were p(INSP) 16.5 +/- 5 cm H2O and p(exp) 8.8 +/- 4 cm H2O. none of the patients refused NIV. In six patients NIV was not initiated immediately together with medical therapeutics. one patient required Ti and the other 16 (94%) improved after NIV. After the acpe episode had resolved, fourteen patients (82%) were eventually discharged from hospital whereas 3 (18%) died during hospitalization. We observed a statistically significant improvement after one hour of NIV in respiratory and pulse rate, arterial pH, PaCO2 and peripheral blood O2 saturation. Despite the small sample size, these results suggest that it is possible to use NIV in the treatment of ACPE outside the ICU, without increasing the risks of TI or decreasing efficacy. In these cases NIV probably accelerates clinical resolution and relieves symptoms

Sustained-Release Bupropion Overdose: A Case Report

Bupropion is an atypical antidepressant with a unique aminoketone structure similar to amphetamines. A narrow therapeutic margin is evident from observational studies that show seizure activity with doses of 400-600 mg or higher. A 38-year old woman took an overdose of 6 grams of bupropion with 110 grams of alcohol. She presented to the Emergency Department with agitation, visual hallucinations and myoclonus of the upper limbs; eyes spontaneously open with isochoric and light reactive pupils with horizontal nystagmus; afebrile, normotensive (121/63 mm Hg) and tachycardic (120 beats/minute). The electrocardiogram revealed a sinus tachycardia with prolonged QT interval (QT/QTc: 0.46/ 0.537) and a QRS complex length in the upper limit of normal. Arterial blood gases revealed metabolic acidosis (pH = 7.16) with increased anion-gap (value=18). She developed mal epilepticus needing thiopental induced coma and Intensive Care Unit (ICU) admission. She suffered prolonged symptoms including seizures before fully recovering. The narrow therapeutic range and the increasing use in the treatment of smoking cessation boosted the number of intentional and unintentional poisoning by this drug. Previous reports of bupropion overdose almost all involve the immediate release formulation. There are some reports of overdose with sustained-release formulation, but there is limited information on its spectrum of toxicity
