Delay for admission of unstable hospitalized patients to intensive care unit: a need for a medical emergency team?

INTRODUCTION. Patients admitted in Intensive Care Unit (ICU) from general wards are more severe and have a higher mortality than those admitted from emergency department as reported [1]. The majority of them develop signs of instability (e.g. tachypnea, tachycardia, hypotension, decreased oxygen saturation and change in conscious state) several hours before ICU admission. Considering this fact and that in-hospital cardiac arrests and unexpected deaths are usually preceded by warning signs, immediate on site intervention by specialists may be effective. This gave an impulse to medical emergency team (MET) implementation, which has been shown to decrease cardiac arrest, morbidity and mortality in several hospitals. OBJECTIVES AND METHODS. In order to verify if the same was true in our hospital and to determine if there was a need for MET, we prospectively collected all non elective ICU admissions of already hospitalized patients (general wards) and of patients remaining more than 3 h in emergency department (considered hospitalized). Instability criteria leading to MET call correspond to those described in the literature. The delay between the development of one criterion and ICU admission was registered. RESULTS. During an observation period of 12 months, 321 patients with our MET criteria were admitted to ICU. 88 patients came from the emergency department, 115 from the surgical and 113 from the medical ward. 65% were male. The median age was 65 years (range 17-89). The delay fromMETcriteria development to ICU admission was higher than 8 h in 155 patients, with a median delay of 32 h and a range of 8.4 h to 10 days. For the remaining 166 patients, an early MET criterion was present up to 8 h (median delay 3 h) before ICU admission. These results are quite concordant with the data reported in the literature (ref 1-8). 122 patients presented signs of sepsis or septic shock, 70 patients a respiratory failure, 58 patients a cardiac emergency. Cardiac arrest represent 5% of our collective of patients. CONCLUSIONS.Similar to others observations, the majority of hospitalized patients admitted on emergency basis in our ICU have warning signs lasting for several hours. More than half of them were unstable for more than 8 h. This shows there is plenty of time for early acute management by dedicated and specialized team such as MET. However, further studies are required to determine if MET implementation can reduce in-hospital cardiac arrests and influence the morbidity, the length of stay and the mortality.

Delirium auf der Intensivstation [Delirium in the intensive care unit.]

The prevalence of delirium in the Intensive Care Unit (ICU) is reported to vary from 20 to 80 %. Delirium in the ICU is not only a frightening experience for the patient and his or her family, it is also a challenge for the nurses and physicians taking care of the patient. Furthermore, it is also associated with worse outcome, prolonged hospitalisation, increased costs, long-term cognitive impairment and higher mortality rates. Thus, strategies to prevent ICU-delirium in addition to the early diagnosis and treatment of delirium are important. The pathophysiology of delirium is still incompletely understood, but numerous risk factors for the development of delirium have been identified in ICU-patients, among which are potentially modifiable factors such as metabolic disturbances, hypotension, anaemia, fever and infection. Key factors are the prevention and management of common risk factors, including avoiding overzealous sedation and analgesia and creating an environment that enhances reintegration. Once delirium is diagnosed, treatment consists of the use of typical and atypical antipsychotics. Haloperidol is still the drug of choice for the treatment of delirium and can be given intravenously in incremental doses of 1 to 2 to 5 (to 10) mg every 15 - 20 minutes.

Comfort of the patient's family in an Intensive Care Unit related to welcoming

This study aimed to identify the level of comfort of families of patients in a critical health condition related to the welcoming practices performed by the hospital staff. Interviews were conducted with 250 relatives in hospitals of the state Bahia, using a Likert scale. Data were analyzed as percentages and quartiles. For nine of the 12 statements of the scale, most relatives scored their comfort level between very and totally comfortable, median of 4,revealing kindness, tranquility and friendly communication with family members. More than half of the sample scored its level as not at all to more or less comfortable, median of 3, for statements about demonstration of interest towards the relative by the staff and flexible visiting of the patient. The necessity of greater interest of the team in the condition and needs of the family was observed. Promoting comfort from the dimension of welcoming demands interdisciplinary actions grounded in humanistic philosophy, in which the nurse has an important role to play.

Dysfunctional psychological responses among Intensive Care Unit nurses: a systematic review of the literature

AbstractOBJECTIVETo systematically review evidence on dysfunctional psychological responses of Intensive Care Units nurses (ICUNs), with focus on anxiety and depressive symptoms and related factors.METHODA literature search was performed in CINAHL, PubMed and Scopus databases, from 1999 to present, along with a critical appraisal and synthesis of all relevant data. The following key words, separately and in combination, were used: "mental status" "depressive symptoms" "anxiety" "ICU nurses" "PTSD" "burnout" "compassion fatigue" "psychological distress".RESULTSThirteen quantitative studies in English and Greek were included. The results suggested increased psychological burden in ICUNs compared to other nursing specialties, as well as to the general population.CONCLUSIONSStudies investigating psychological responses of ICUNs are limited, internationally. Future longitudinal and intervention studies will contribute to a better understanding of the phenomenon.

Interrater reliability of Nursing Activities Score among Intensive Care Unit health professionals

ABSTRACT Objective To analyze the interrater reliability of NAS among critical care nurses and managers in an ICU. Method This was a methodological study performed in an adult, general ICU in Norway. In a random selection of patients, the NAS was scored on 101 patients by three raters: a critical care nurse, an ICU physician and a nurse manager. Interrater reliability was analyzed by agreement between groups and kappa statistics. Results The mean NAS were 88.4 (SD=16.2) and 88.7 (SD=24.5) respectively for the critical care nurses and nurse managers. A lower mean of 83.7 (SD=21.1) was found for physicians. The 18 medical interventions showed higher agreement between critical care nurses and physicians (85.6%), than between critical care nurses and nurse managers (78.7). In the five nursing activities the Kappa-coefficients were low for all activities in all compared groups. Conclusion The study indicated a satisfactory agreement of nursing workload between critical care nurses and managers.

Nursing Activities Score: an updated guideline for its application in the Intensive Care Unit

ABSTRACT Objective To describe nursing workload in Intensive Care Units (ICU) in different countries according to the scores obtained with Nursing Activities Score (NAS) and to verify the agreement among countries on the NAS guideline interpretation. Method This cross-sectional study considered 1-day measure of NAS (November 2012) obtained from 758 patients in 19 ICUs of seven countries (Norway, the Netherlands, Spain, Poland, Egypt, Greece and Brazil). The Delphi technique was used in expertise meetings and consensus. Results The NAS score was 72.8% in average, ranging from 44.5% (Spain) to 101.8% (Norway). The mean NAS score from Poland, Greece and Egypt was 83.0%, 64.6% and 57.1%, respectively. The NAS score was similar in Brazil (54.0%) and in the Netherlands (51.0%). There were doubts in the understanding of five out 23 items of the NAS (21.7%) which were discussed until researchers’ consensus. Conclusion NAS score were different in the seven countries. Future studies must verify if the fine standardization of the guideline can have a impact on differences in the NAS results.

Continuous electroencephalography in the medical intensive care unit.

OBJECTIVES: To examine predictors and the prognostic value of electrographic seizures (ESZs) and periodic epileptiform discharges (PEDs) in medical intensive care unit (MICU) patients without a primary acute neurologic condition. DESIGN: Retrospective study. SETTING: MICU in a university hospital. PATIENTS: A total of 201 consecutive patients admitted to the MICU between July 2004 and January 2007 without known acute neurologic injury and who underwent continuous electroencephalography monitoring (cEEG) for investigation of possible seizures or changes in mental status. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Median time from intensive care unit (ICU) admission to cEEG was 1 day (interquartile range 1-4). The majority of patients (60%) had sepsis as the primary admission diagnosis and 48% were comatose at the time of cEEG. Ten percent (n = 21) of patients had ESZs, 17% (n = 34) had PEDs, 5% (n = 10) had both, and 22% (n = 45) had either ESZs or PEDs. Seizures during cEEG were purely electrographic (no detectable clinical correlate) in the majority (67%) of patients. Patients with sepsis had a higher rate of ESZs or PEDs than those without sepsis (32% vs. 9%, p < 0.001). On multivariable analysis, sepsis at ICU admission was the only significant predictor of ESZs or PEDs (odds ratio 4.6, 95% confidence interval 1.9-12.7, p = 0.002). After controlling for age, coma, and organ dysfunction, the presence of ESZs or PEDs was associated with death or severe disability at hospital discharge (89% with ESZs or PEDs, vs. 39% if not; odds ratio 19.1, 95% confidence interval 6.3-74.6, p < 0.001). CONCLUSION: In this retrospective study of MICU patients monitored with cEEG, ESZs and PEDs were frequent, predominantly in patients with sepsis. Seizures were mainly nonconvulsive. Both seizures and periodic discharges were associated with poor outcome. Prospective studies are warranted to determine more precisely the frequency and clinical impact of nonconvulsive seizures and periodic discharges, particularly in septic patients.

Prospective monitoring of cefepime in intensive care unit adult patients

Rapport de synthèse :Le céfépime a été associé à un taux de mortalité supérieur à celui des autres bêta-lactamines chez les patients traités pour un sepsis sévère. Une des hypothèses avancées pour expliquer ces échecs thérapeutiques sont de possibles effets secondaires cachés (par ex. neurologiques) ou des paramètres pharmacocinétiques/pharmacodynamiques (PK/PD) inadaptés. Le présent travail a étudié cette problématique en mesurant prospectivement la pharmacocinétique du céfépime chez 21 patients consécutifs hospitalisés aux soins intensifs adultes (SIAD) pour une pneumonie nosocomiale. La population étudiée avec un âge médian 55,1 ans, a reçu par voie intraveineuse du céfépime à raison de 2 g toutes les 12 heures pour une clairance de la créatinine (Clcr)>50 mI/ min, et 2 g toutes les 24 heures ou 36 heures pour une Clcr<50 ml /min. Les taux plasmatiques de céfépime ont été mesurés à plusieurs reprises avant et après administration du médicament après la lèoe dose et à l'état d'équilibre par chromatographie en phase liquide à haute pression. Les taux plasmatiques ont considérablement varié entre les patients. Cent pour cent (21/21) des patients ont eu une durée appropriée d'antibiothérapie avec des taux plasmatiques supérieures à la CMI du céfépime (T>CMI>50%) pour les agents pathogènes retrouvés dans cette étude (CMI<4 mg/I), mais seulement 45-65% d'entre eux ont eu une couverture appropriée pour les agents pathogènes potentiels présentant une CMI> 8 mg/I pour le céfépime. Deux patients avec une insuffisance rénale (Clcr<30 ml/min) ont présenté des symptômes compatibles avec une épilepsie non-convulsive (état confusionnel et myoclonies) attribuée dans un 2ème temps à une toxicité du céfépime après que les taux plasmatiques aient été communiqués aux soignants qui ont suspendu l'antibiothérapie avec disparition des symptômes. Les résultats de cette étude empirique confirment l'existence d'effets secondaires cachés et de paramètres PK/PD inappropriés (pour les agents pathogènes ayant des CMI de limite supérieure) dans notre population de SIAD. En outre, ils mettent en évidence une fenêtre thérapeutique efficace pour une posologie de céfépime de 2 g toutes les 12 heures chez les patients ayant une Clcr>50 ml/min infectés par des pathogènes avec des CMI pour le céfépime <4 mg/I. Les échecs thérapeutiques constatés dans cette étude sont probablement liés à des taux sériques inadaptés, résultant de la difficulté de prescription dans les situations cliniques complexes. Dans ce contexte, un prompt dosage plasmatique du céfépime doit être considéré en cas de diminution de la Clcr ou en présence de CMI élevées.

Pharmaceutical care in an inpatient pediatric intensive care unit: an international multicentric study

Introduction Pediatric intensive care patient represent a population athigh risk for drug-related problems. Our objective is to describe drugrelated problems and intervention of four decentralized pharmacists inpediatric and cardiac intensive care unit.Materials & Methods Multicentric, descriptive and prospectivestudy over a six-month period (August 1st 2009-January 31st 2010).Drug-related problems and clinical interventions were compiled infour pediatric centers using a tool developed by the Socie´te´ Franc¸aisede Pharmacie Clinique. Data concerning patients, drugs, intervention,documentation, approval (if needed), and estimated impact werecompiled. The four pharmacists participating were from Belgium (B),France (F), Quebec (Q) and Switzerland (S).Results A total of 996 interventions were collected: 129 (13%) in B,238 (24%) in F, 278 (28%) in Q and 351 (35%) in S. These interventionstargeted 269 patients (median 22 month-old, 52% male): 69(26%) in B, 88 (33%) in F, 56 (21%) in Q and in S. These data werecollected during 28 non consecutive days in the clinical unit in B, 59days in F, 42 days in Q and 63 days in S. The main drug-relatedproblems were inappropriate administration technique (293, 29%),untreated indication (254, 25%) and supra therapeutic dosage (106,11%). The pharmacist's interventions concerned mainly administrationmode optimization (223, 22%), dose adjustment (200, 20%) andtherapeutic monitoring (164, 16%). The three major drug classesleading to interventions were anti-infectives for systemic use (233,23%) and alimentary tract and metabolism drugs (218, 22%). Interventionsconcerned mainly residents and all clinical staff (209, 21%).Among the 879 (88%) interventions requiring a physician's approval,731 (83%) were accepted. Interventions were considered as having amoderate (51%) or major (17%) clinical impact. Among the interventionsprovided, 10% were considered to have an economicalpositive impact. Differences and similarities between countries willbe presented at the poster session.Discussion & Conclusion Decentralized pharmacist at patient bedsideis a pre-requisite for pharmaceutical care. There are limitedstudies comparing the activity of clinical pharmacists betweencountries. This descriptive study illustrates the ability of clinicalpharmacist to identify and solve drug-related problems in pediatricintensive care unit in four different francophone countries.

Prevalence and factors of intensive care unit conflicts: the conflicus study.

RATIONALE: Many sources of conflict exist in intensive care units (ICUs). Few studies recorded the prevalence, characteristics, and risk factors for conflicts in ICUs. OBJECTIVES: To record the prevalence, characteristics, and risk factors for conflicts in ICUs. METHODS: One-day cross-sectional survey of ICU clinicians. Data on perceived conflicts in the week before the survey day were obtained from 7,498 ICU staff members (323 ICUs in 24 countries). MEASUREMENTS AND MAIN RESULTS: Conflicts were perceived by 5,268 (71.6%) respondents. Nurse-physician conflicts were the most common (32.6%), followed by conflicts among nurses (27.3%) and staff-relative conflicts (26.6%). The most common conflict-causing behaviors were personal animosity, mistrust, and communication gaps. During end-of-life care, the main sources of perceived conflict were lack of psychological support, absence of staff meetings, and problems with the decision-making process. Conflicts perceived as severe were reported by 3,974 (53%) respondents. Job strain was significantly associated with perceiving conflicts and with greater severity of perceived conflicts. Multivariate analysis identified 15 factors associated with perceived conflicts, of which 6 were potential targets for future intervention: staff working more than 40 h/wk, more than 15 ICU beds, caring for dying patients or providing pre- and postmortem care within the last week, symptom control not ensured jointly by physicians and nurses, and no routine unit-level meetings. CONCLUSIONS: Over 70% of ICU workers reported perceived conflicts, which were often considered severe and were significantly associated with job strain. Workload, inadequate communication, and end-of-life care emerged as important potential targets for improvement.

Pédiatrie. 1. Comment favoriser le développement de l'oralité en néonatologie [Pediatrics. How can we improve oral feeding in the neonatal intensive care unit?].

Preterm or sick neonates are frequently hampered in establishing a safe and efficient oral feeding. This can delay hospital discharge and impact on parent-child bonding, growth or neurodevelopment. Recent researches identified a pattern of interventions that could allow to reduce these troubles and to shorten hospital stays.
