[Meningitis/Encephalitis diagnosis in ICU using Multiplex PCR system: Is it time of change?] / Diagnóstico de meningitis/encefalitis en UCI con sistema de PCR múltiple. ¿Es tiempo de cambio?

OBJECTIVE: To evaluate the clinical impact of Meningitis/Encephalitis FilmArray® panel for the diagnosis of cerebral nervous system infection and to compare the results (including time for diagnosis) with those obtained by conventional microbiological techniques. METHODS: A prospective observational study in an Intensive Care Unit of adults from a tertiary hospital was carried out. Cerebrospinal fluid from all patients was taken by lumbar puncture and assessed by the meningitis/encephalitis FilmArray® panel ME, cytochemical study, Gram, and conventional microbiological cultures. RESULTS: A total of 21 patients admitted with suspicion of Meningitis/Encephalitis. Median age of patients was 58.4 years (RIQ 38.1-67.3), median APACHE II 18 (RIQ 12-24). Median stay in ICU and median hospital stay was 4 (RIQ 2-6) and 17 days (RIQ 14-28), respectively. The overall mortality was 14.3%. A final clinical diagnosis of meningitis or encephalitis was established in 16 patients, obtaining the etiological diagnosis in 12 of them (75%). The most frequent etiology was Streptococcus pneumoniae (8 cases). FilmArray® allowed etiological diagnosis in 3 cases in which the culture had been negative, and the results led to changes in the empirical antimicrobial therapy in 7 of 16 cases (43.8%). FilmArray® yielded a global sensitivity and specificity of 100% and 90%, respectively. The median time to obtain results from the latter and conventional culture (including antibiogram) was 2.9 hours (RIQ 2.1-3.8) and 45.1 hours (RIQ 38.9-58.7), respectively. CONCLUSIONS: The Meningitis/Encephalitis FilmArray® panel was able to establish the etiologic diagnosis faster than conventional methods. Also, it achieved a better sensitivity and led to prompt targeted antimicrobial therapy.

Nosocomial ventriculitis caused by a meticillin- and linezolid-resistant clone of Staphylococcus epidermidis in neurosurgical patients.

BACKGROUND: Postneurosurgical ventriculitis is mainly caused by coagulase-negative staphylococci. The rate of linezolid-resistant Staphylococcus epidermidis (LRSE) is increasing worldwide. AIMS: To report clinical, epidemiological and microbiological data from a series of ventriculitis cases caused by LRSE in a Spanish hospital between 2013 and 2016. METHODS: Cases of LRSE ventriculitis were reviewed retrospectively in a Spanish hospital over a four-year period. Clinical/epidemiological data of the infected patients were reviewed, the isolates involved were typed by pulsed-field gel electrophoresis (PFGE) and multi-locus sequence typing, and the molecular bases of linezolid resistance were determined. FINDINGS: Five cases of LRSE ventriculitis were detected. The patients suffered from cerebral haemorrhage or head trauma that required the placement of an external ventricular drain; spent a relatively long time in the intensive care unit (ICU) (10-26 days); and three out of the five patients had previously been treated with linezolid. All LRSE had the same PFGE pattern, belonged to ST2, and shared an identical mechanism of linezolid resistance. Specifically, all had the G2576T mutation in the V domain of each of the six copies of the 23S rRNA gene, together with the Q136L and M156T mutations and the 71GGR72 insertion in the L3 and L4 ribosomal proteins, respectively. CONCLUSION: The high ratio of linezolid consumption in the ICU (7.72-8.10 defined daily dose/100 patient-days) could have selected this resistant clone, which has probably become endemic in the ICU where it could have colonized admitted patients. Infection control and antimicrobial stewardship interventions are essential to prevent the dissemination of this difficult-to-treat pathogen, and to preserve the therapeutic efficacy of linezolid.

Results and functional outcomes of acute ischemic stroke patients who underwent mechanical thrombectomy admitted to intensive care unit. / Resultados y evolución funcional de pacientes críticos con ictus isquémico sometidos a trombectomía mecánica.

PURPOSE: To study the results and complications of endovascular treatment (EVT) in acute ischemic stroke patients admitted to Intensive Care Unit (ICU). To analyse the possible factors related to mortality and level of disability at ICU discharge and one year after stroke. DESIGN: Observational prospective study. SETTING: Mixed ICU. Third level hospital. PATIENTS: Sixty adult patients. Consecutive sample. INTERVENTIONS: None. VARIABLES OF INTEREST: Epidemiological data, time from symptom onset to EVT, angiographic result, length of stay, days on mechanical ventilation, neurological complications, National Institutes of Health Stroke Scale (NIHSS) at ICU admission and discharge, modified Rankin scale score (mRS) at one year. RESULTS: Mean age 68,90±8,84years. Median time from symptom onset to EVT: 180minutes. Median NIHSS at admission: 17,5; at discharge: 3. Distal flow was achieved in 90% of cases. Median ICU stay: 3 days. Mechanical ventilation: 81,7.%. Functional independence (mRS≤2) 50% at one year. Deaths: 22 (36,6%) of which 8 (13,3%) died during UCI stay and the rest during the first year. CONCLUSIONS: The factors relating to a worse functional outcome were symptomatic hemorrhage transformation, lack of recanalization and complications during EVT. The factors relating to mortality were symptomatic hemorrhage and hydrocephalus. Distal flow was achieve in most cases with a low complication rate. Half of the patients presented functional independence one year after the stroke.

Infectious complications related to external ventricular shunt. Incidence and risk factors. / Complicaciones infecciosas relacionadas con el drenaje ventricular externo. Incidencia y factores de riesgo.

OBJECTIVE: Infectious complications related to external ventricular shunt (ICREVS) are a main problem in neurocritical intensive care units (ICU). The aim of the review is to assess the incidence of ICREVS and to analyse factors involved. METHODS: Retrospective analysis, adult polyvalent ICU in a third level reference hospital. Patients carrying external ventricular shunt (DVE) were included. Those patients with central nervous system infection diagnosed prior DVE placement were excluded. RESULTS: 87 patients were included with 106 DVE. Most common admittance diagnosis was subarachnoid haemorrhage (49.4%). 31 patients with 32 DVE developed an ICREVS. Infection rate is 19.5 per 1000 days of shunt for ICREVS and 14 per 1000 days for ventriculitis. 31.6% of the patients developed ICREVS and 25.3% ventriculitis. Patients who developed ICREVS presented higher shunt manipulations (2.0 ± 0.6 vs. 3.26 ± 1.02, p=0.02), shunt repositioning (0.1 ± 0.1 vs. 0.2 ± 0.1) and ICU and hospital stay (29.8 ± 4.9 vs 49.8 ± 5.2, p<0.01 y 67.4 ± 18.8 vs. 108.9 ± 30.2, p=0.02. Those DVE with ICREVS were placed for longer not only at infection diagnosis but also at removal (12.6 ± 2.1 vs. 18.3 ± 3.6 and 12.6 ± 2.1 vs. 30.4 ± 7.3 days, p<0.01). No difference in mortality was found. CONCLUSIONS: One out of three patients with a DVE develops an infection. The risk factors are the number of manipulations, repositioning and the permanency days. Patients with ICREVS had a longer ICU and hospital average stay without an increase in mortality.

[Visitation policy, design and comfort in Spanish intensive care units]. / Política de visitas, diseño y confortabilidad en las unidades de cuidados intensivos españolas.

OBJECTIVE: To determine the design and comfort in the Intensive Care Units (ICUs), by analysing visiting hours, information, and family participation in patient care. DESIGN: Descriptive, multicentre study. SETTING: Spanish ICUs. METHODS: A questionnaire e-mailed to members of the Spanish Society of Intensive Care Medicine, Critical and Coronary Units (SEMICYUC), subscribers of the Electronic Journal Intensive Care Medicine, and disseminated through the blog Proyecto HU-CI. RESULTS: A total of 135 questionnaires from 131 hospitals were analysed. Visiting hours: 3.8% open 24h, 9.8% open daytime, and 67.7% have 2 visits a day. Information: given only by the doctor in 75.2% of the cases, doctor and nurse together in 4.5%, with a frequency of once a day in 79.7%. During weekends, information is given in 95.5% of the cases. Information given over the phone 74.4%. Family participation in patient care: hygiene 11%, feeding 80.5%, physiotherapy 17%. Personal objects allowed: mobile phone 41%, computer 55%, sound system 77%, and television 30%. Architecture and comfort: all individual cubicles 60.2%, natural light 54.9%, television 7.5%, ambient music 12%, clock in the cubicle 15.8%, environmental noise meter 3.8%, and a waiting room near the ICU 68.4%. CONCLUSIONS: Visiting policy is restrictive, with a closed ICU being the predominating culture. On average, technological communication devices are not allowed. Family participation in patient care is low. The ICU design does not guarantee privacy or provide a desirable level of comfort.
