Main barriers to effective implementation of stroke care pathways in France: a qualitative study.

BACKGROUND: Stroke Care Pathways (SCPs) aim to improve quality of care by providing better access to stroke units, rehabilitation centres, and home care for dependent patients. The objective of this study was to identify the main barriers to effective implementation of SCPs in France. METHODS: We selected 4 types of SCPs currently implemented in France that differed in terms of geographical location, population size, socio-economic conditions, and available health care facilities. We carried out 51 semi-structured interviews of 44 key health professionals involved in these SCPs and used the interview data to (i) create a typology of the organisational barriers to effective SCP implementation by axial coding, (ii) define barrier contents by vertical coding. The typology was validated by a panel of 15 stroke care professionals. RESULTS: Four main barriers to effective SCP implementation were identified: lack of resources (31/44 interviewees), coordination problems among staff (14/44) and among facilities (27/44), suboptimal professional and organisational practices (16/44), and inadequate public education about stroke (13/44). Transposition of the findings onto a generic SCP highlighted alternative care options and identified 10 to 17 barriers that could disrupt continuity of care. CONCLUSION: Lack of resources was considered to be the chief obstacle to effective SCP implementation. However, the main weakness of existing SCPs was poor communication and cooperation among health professionals and among facilities. We intend to use this knowledge to construct a robust set of quality indicators for use in SCP quality improvement initiatives, in comparisons between SCPs, and in the assessment of the effective implementation of clinical practice guidelines.

Hospital performance based on treatment delays: comparison of ranking methods.

BACKGROUND: Reducing time-to-care is crucial in many acute and chronic diseases. Quality indicators based on target delays derived from guidelines are used to compare hospital performance but there is no accepted methodology for comparing performance when no target delay has been established. AIM: To explore by different statistical methods the uncertainty in hospital comparisons that are based on delay indicators, when no target delay is available. METHODS: Data for hospital door-to-needle time were extracted from a 2010 study of 1699 patients in 57 hospitals with ST-elevated myocardial infarction. We determined whether the times in each hospital were statistically different from the overall mean time or the median time for all hospitals by (i) one-way analysis of variance (ANOVA), (ii) non-parametric ANOVA with Nelson-Hsu adjustment (ANOVA R) and (iii) the proportional hazard model (PHM). We also tested for the assumptions underlying the methods: normal distribution for ANOVA, homogeneity of variances (homoscedasticity) for ANOVA and ANOVA R, and proportionality for PHM. RESULTS: Door-to-needle times were available for 889 patients in 44 hospitals. Data distribution was not Gaussian. Test assumptions were verified for ANOVA R (homoscedasticity) for one data subset (>48-h times (48H) excluded) and for PHM (proportionality) for two data subsets (48H or >95th percentile (P95) times excluded). The same five significantly better performers were identified in each case (although ANOVA R missed one). ANOVA R (48H) identified two significantly poorer performers, PHM (48H) identified three and PHM (P95) just one. Poorer performers differed according to method. CONCLUSIONS: The tested statistical methods yielded broadly similar results but no method was truly satisfactory. A transparency statement should therefore always specify the ranking method used to compare hospital performance.

Symptom-to-needle times in ST-segment elevation myocardial infarction: shortest route to a primary coronary intervention facility.

BACKGROUND: Primary percutaneous coronary intervention (PCI) is the preferred management for patients with acute ST-segment elevation myocardial infarction (STEMI) if performed in a timely manner by experienced providers. Patients can access a PCI facility by three routes: prehospital STEMI diagnosis by emergency medical services (EMS) and direct transport by EMS to a PCI facility (EMS-PCI); visit to a hospital emergency department (ED) followed by referral to an on-site PCI facility (ED-PCI); or transfer from the ED to a PCI facility in another hospital (ED-transfer-PCI). AIMS: To assess the implementation rate in France of the guidelines recommending that STEMI patients be transported by EMS to a PCI facility and to compare the times between symptom onset and PCI for these three routes. METHODS: We used the results of the pilot testing of a national quality indicator programme on STEMI in 64 hospitals, providing data on patient characteristics, referral route and symptom-onset-to-needle time. We compared delays for each route in a Cox proportional-hazard model. RESULTS: In a population of 1217 patients, median symptom-onset-to-needle time was 186minutes (Q1 133; Q3 292) for the EMS-PCI route, 237minutes (Q1 165; Q3 368) for the ED-PCI route and 305minutes (Q1 230; Q3 570) for the ED-transfer-PCI route. A total of 70.8% of patients were transported by EMS as recommended. After adjustment for age, symptom onset period (weekends/nights) and history of cardiovascular disease, the EMS-PCI route was associated with the shortest symptom-onset-to-needle times. The hazard ratio was 0.71 [0.59-0.86] for the ED-PCI route and 0.67 [0.52-0.86] for the ED-transfer-PCI route. CONCLUSION: STEMI patients receive prompter care after prehospital diagnosis and direct transport to a PCI facility by EMS than by visiting a hospital ED. Use of this referral route should be further encouraged in France as approximately one-third of STEMI patients are still presenting directly to the ED.

The role of calling EMS versus using private transportation in improving the management of stroke in France.

OBJECTIVE: To compare the time from symptom onset to brain imaging between patients calling emergency medical services (EMS) and those using private means for transportation. METHODS: We focused on symptom onset-to-brain imaging times of ≤2 hours and ≤3 hours 30 minutes, assuming a one-hour interval between imaging and thrombolysis. Other variables were the patient's age, gender, stroke type, National Institutes of Health Stroke Scale (NIHSS) score, presence of an on-site stroke unit, and period of symptom onset. Univariate analyses and a hierarchical linear regression model were used, as appropriate, and adjusted for these variables. RESULTS: A total of 1,105 stroke patients (28%) were included in the analyses, 40.6% of them transported by EMS. Patients using EMS were significantly older (72.8 vs. 70.5 years; p = 0.008), they had a higher NIHSS score (8 vs. 6.1; p = 0.0001), fewer were ischemic (85.1% vs. 90.6%; p = 0.005), and more of them reached hospitals with an on-site stroke unit (81.3% vs. 72.9%; p = 0.002). For the EMS-call patients, the median symptom onset-to-brain imaging time was significantly shorter (3 hours 21 minutes vs. 5 hours 57 minutes), and after adjustment, maximum delays of 2 hours and 3 hours 30 minutes were independently associated with EMS call: 28% vs. 18% (p = 0.015) and 66% vs. 45% (p < 0.0001) of patients, respectively, leading to an adjusted odds ratio of 2.77 (95% confidence interval, 2.007-3.828; p < 0.0001) for the threshold of 3 hours 30 minutes. CONCLUSIONS: The symptom onset-to-brain imaging time was significantly shorter in case of EMS transportation, but most patients did not reach the hospital in time to be eligible for thrombolysis. Efforts are still needed to reduce delays, especially public education and EMS activation. These efforts should be combined with new approaches for the quality management of stroke patients.

Method for developing national quality indicators based on manual data extraction from medical records.

Developing quality indicators (QI) for national purposes (eg, public disclosure, paying-for-performance) highlights the need to find accessible and reliable data sources for collecting standardised data. The most accurate and reliable data source for collecting clinical and organisational information still remains the medical record. Data collection from electronic medical records (EMR) would be far less burdensome than from paper medical records (PMR). However, the development of EMRs is costly and has suffered from low rates of adoption and barriers of usability even in developed countries. Currently, methods for producing national QIs based on the medical record rely on manual extraction from PMRs. We propose and illustrate such a method. These QIs display feasibility, reliability and discriminative power, and can be used to compare hospitals. They have been implemented nationwide in France since 2006. The method used to develop these QIs could be adapted for use in large-scale programmes of hospital regulation in other, including developing, countries.

Contribution of the ethics committee of the French Intensive Care Society to describing a scenario for implementing organ donation after Maastricht type III cardiocirculatory death in France.

French law allows organ donation after death due to cardiocirculatory arrest. In the Maastricht classification, type III non-heart-beating donors are those who experience cardiocirculatory arrest after the withdrawal of life-sustaining treatments. French authorities in charge of regulating organ donation (Agence de la Biomédecine, ABM) are considering organ collection from Maastricht type III donors. We describe a scenario for Maastricht type III organ donation that fully complies with the ethical norms governing care to dying patients. That organ donation may occur after death should have no impact on the care given to the patient and family. The dead-donor rule must be followed scrupulously: the organ retrieval procedure must neither cause nor hasten death. The decision to withdraw life-sustaining treatments, withdrawal modalities, and care provided to the patient and family must adhere strictly to the requirements set forth in patient-rights legislation (the 2005 Léonetti law in France) and should not be influenced in any way by the possibility of organ donation. A major ethical issue regarding the family is how best to transition from discussing treatment-withdrawal decisions to discussing possible organ retrieval for donation should the patient die rapidly after treatment withdrawal. Close cooperation between the healthcare team and the organ retrieval team is crucial to minimize the distress of family members during this transition. Modalities for implementing Maastricht type III organ donation are discussed here, including the best location for withdrawing life-sustaining treatments (operating room or intensive care unit).

Development and feasibility of a set of quality indicators relative to the timeliness and organisation of care for new breast cancer patients undergoing surgery.

BACKGROUND: Because breast cancer is a major public health issue, it is particularly important to measure the quality of the care provided to patients. Survival rates are affected by the timeliness of care, and waiting times constitute key quality criteria. The aim of this study was to develop and validate a set of quality indicators (QIs) relative to the timeliness and organisation of care in new patients with infiltrating, non-inflammatory and metastasis-free breast cancer undergoing surgery. The ultimate aim was to use these QIs to compare hospitals. METHODS: The method of QI construction and testing was developed by COMPAQ-HPST. We first derived a set of 8 QIs from consensus guidelines with the aid of experts and professional associations and then tested their metrological properties in a panel of 60 volunteer hospitals. We assessed feasibility using a grid exploring 5 dimensions, discriminatory power using the Gini coefficient as a measure of dispersion, and inter-observer reliability using the Kappa coefficient. RESULTS: Overall, 3728 records were included in the analyses. All 8 QIs showed acceptable feasibility (but one QI was subject to misinterpretation), fairly strong agreement between observers (Kappa = 0.66), and wide variations in implementation among hospitals (Gini coefficient < 0.45 except for QI 6 (patient information)). They are thus suitable for use to compare hospitals and measure quality improvement. CONCLUSIONS: Of the 8 QIs, 3 are ready for nationwide implementation (time to surgery, time to postoperative multidisciplinary team meeting (MDTM), conformity of MDTM). Four are suitable for use only in hospitals offering surgery with on-site postoperative treatment (waiting time to first appointment after surgery, patient information, time to first postoperative treatment, and traceability of information relating to prognosis). Currently, in the French healthcare system, a patient receives cancer care from different institutions whose databases cannot as yet be easily merged. Nationwide implementation of QIs covering the entire care pathway will thus be a challenge.

Clinical and economic impact of malnutrition per se on the postoperative course of colorectal cancer patients.

BACKGROUND & AIMS: To assess the medico-economic impact of malnutrition in patients who underwent surgery for colorectal cancer. METHODS: We performed post-hoc analyses of data from the Alves et al. prospective study. Using standard criteria of malnutrition, 2 groups were created a posteriori: Well-nourished (WN) and Mal-nourished (MN) patients. The 2 groups were statistically adjusted for age, cancer status, and scheduled surgery. Individual costs were valued using the French National Cost Study. Postoperative morbidity, mortality, hospital length-of-stay (LOS), and discharge setting were compared. We defined 3 scenarios, the most accurate estimate and its upper and lower limits, to assess the economic impact of malnutrition. RESULTS: 453 patients were included in the analyses. Complication and mortality rates were not significantly different between the 2 groups. MN patients had a mean LOS 3.41 days significantly longer than WN patients (p = 0.017). In MN patients, the cost of hospital stay was increased by around 3360 €, creating an annual impact of 10,159,436 € for French non-profit hospitals. CONCLUSIONS: Malnutrition in colorectal cancer surgical patients is associated with an increased LOS resulting in significant budget impact. Further studies are needed to investigate this impact and the related cost-benefit of perioperative specialized nutritional support and implementation of the ERAS protocol in this homogeneous category of patients.

A prospective randomised multi-centre controlled trial on tight glucose control by intensive insulin therapy in adult intensive care units: the Glucontrol study.

PURPOSE: An optimal target for glucose control in ICU patients remains unclear. This prospective randomized controlled trial compared the effects on ICU mortality of intensive insulin therapy (IIT) with an intermediate glucose control. METHODS: Adult patients admitted to the 21 participating medico-surgical ICUs were randomized to group 1 (target BG 7.8-10.0 mmol/L) or to group 2 (target BG 4.4-6.1 mmol/L). RESULTS: While the required sample size was 1,750 per group, the trial was stopped early due to a high rate of unintended protocol violations. From 1,101 admissions, the outcomes of 542 patients assigned to group 1 and 536 of group 2 were analysed. The groups were well balanced. BG levels averaged in group 1 8.0 mmol/L (IQR 7.1-9.0) (median of all values) and 7.7 mmol/L (IQR 6.7-8.8) (median of morning BG) versus 6.5 mmol/L (IQR 6.0-7.2) and 6.1 mmol/L (IQR 5.5-6.8) for group 2 (p < 0.0001 for both comparisons). The percentage of patients treated with insulin averaged 66.2 and 96.3%, respectively. Proportion of time spent in target BG was similar, averaging 39.5% and 45.1% (median (IQR) 34.3 (18.5-50.0) and 39.3 (26.2-53.6)%) in the groups 1 and 2, respectively. The rate of hypoglycaemia was higher in the group 2 (8.7%) than in group 1 (2.7%, p < 0.0001). ICU mortality was similar in the two groups (15.3 vs. 17.2%). CONCLUSIONS: In this prematurely stopped and therefore underpowered study, there was a lack of clinical benefit of intensive insulin therapy (target 4.4-6.1 mmol/L), associated with an increased incidence of hypoglycaemia, as compared to a 7.8-10.0 mmol/L target. (ClinicalTrials.gov # NCT00107601, EUDRA-CT Number: 200400391440).

Nutritional risk factors in planned oncologic surgery: what clinical and biological parameters should be routinely used?

BACKGROUND: Screening for malnutrition is recommended in hospitalized and planned surgical patients. The aim of this study was to analyze the feasibility and routine prognostic value of using the principal recommended nutritional screening and evaluation tools for cancer patients undergoing major surgery. METHODS: This study is a prospective, 3-month, multicenter observational trial recording weight loss, body mass index, albumin, transthyretin, and PG-SGA. The morbidity rate was assessed on the basis of major complications (MC), whether of an infectious (MIC) or noninfectious (MNIC) nature. RESULTS: Two hundred seventy-five patients were recruited at nine centers. The following percentages were recorded with respect to morbidity: 28.4% MC, 12.7% MIC, and 22.2% MNIC. Univariate analysis revealed a statistical association only between weight loss greater than 10% and MIC and hospital stay. A weight loss of 15% is required to demonstrate an association with either MC, MIC, or MNIC. Body mass index (BMI) was associated only with MNIC, PG-SGA with MC, and albumin <30 g/l was strongly associated with all types of morbidity (MC, MIC, MNIC). Multivariate analysis indicated that only albumin <30 g/l and an operating time of more than 4 h are significantly associated with morbidity. CONCLUSIONS: In this study, the best nutritional factor for detecting the risk of MC is albumin levels below 30 g/l. A weight loss greater than 15% is required to obtain a statistically significant correlation with the existence of MC.

Early tracheotomy versus prolonged endotracheal intubation in unselected severely ill ICU patients.

OBJECTIVE: Although several advantages are attributed to tracheotomy in ICU patients requiring mechanical ventilation (MV), true benefits and the optimal timing of tracheotomy remain controversial. In this study, we compared early tracheotomy (ET) with prolonged intubation (PI) in severely ill patients requiring prolonged MV. DESIGN: Prospective, randomized study. SETTING: Twenty-five medical and surgical ICUs in France. PATIENTS: Patients expected to require MV > 7 days. MEASUREMENTS AND RESULTS: Patients were randomised to either (open or percutaneous) ET within 4 days or PI. The primary end-point was 28-day mortality. Secondary end-points were: the incidence of ICU-acquired pneumonia, number of d1-d28 ventilator-free days, time spent in the ICU, 60-day mortality, number of septic episodes, amount of sedation, comfort and laryngeal and tracheal complications. A sample size of 470 patients was considered necessary to obtain a reduction from 45 to 32% in 28-day mortality. After 30 months, 123 patients had been included (ET = 61, PI = 62) in 25 centres and the study was prematurely closed. All group characteristics were similar upon admission to ICU. No difference was found between the two groups for any of the primary or secondary end-points. Greater comfort was the sole benefit afforded by tracheotomy after subjective self-assessment by patients. CONCLUSIONS: The trial did not demonstrate any major benefit of tracheotomy in a general population of ICU patients, as suggested in a previous meta-analysis, but was underpowered to draw any firm conclusions. The potential advantage of ET may be restricted to selected groups of patients.

Norepinephrine plus dobutamine versus epinephrine alone for management of septic shock: a randomised trial.

BACKGROUND: International guidelines for management of septic shock recommend that dopamine or norepinephrine are preferable to epinephrine. However, no large comparative trial has yet been done. We aimed to compare the efficacy and safety of norepinephrine plus dobutamine (whenever needed) with those of epinephrine alone in septic shock. METHODS: This prospective, multicentre, randomised, double-blind study was done in 330 patients with septic shock admitted to one of 19 participating intensive care units in France. Participants were assigned to receive epinephrine (n=161) or norepinephrine plus dobutamine (n=169), which were titrated to maintain mean blood pressure at 70 mm Hg or more. The primary outcome was 28-day all-cause mortality. Analyses were by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00148278. FINDINGS: There were no patients lost to follow-up; one patient withdrew consent after 3 days. At day 28, there were 64 (40%) deaths in the epinephrine group and 58 (34%) deaths in the norepinephrine plus dobutamine group (p=0.31; relative risk 0.86, 95% CI 0.65-1.14). There was no significant difference between the two groups in mortality rates at discharge from intensive care (75 [47%] deaths vs 75 [44%] deaths, p=0.69), at hospital discharge (84 [52%] vs 82 [49%], p=0.51), and by day 90 (84 [52%] vs 85 [50%], p=0.73), time to haemodynamic success (log-rank p=0.67), time to vasopressor withdrawal (log-rank p=0.09), and time course of SOFA score. Rates of serious adverse events were also similar. INTERPRETATION: There is no evidence for a difference in efficacy and safety between epinephrine alone and norepinephrine plus dobutamine for the management of septic shock.

[Can children visit their relatives in an adult ICU?]. / Les enfants peuvent-ils venir visiter leurs parents hospitalisés en réanimation oncohématologique?

For the last three years, our oncology ICU (intensive care unit) has been opened to visiting children between 0 and 18 years. Our objective was to attempt to decrease the psychological burden in critically ill cancer patients and their children. We report here the evaluation of this new policy. Encouraged by the child psychologists in our hospital, we first recorded the opinions of the nursing staff, patients and relatives about this innovative approach. As our preliminary findings were favourable, a liberalised greeting and education policy for visiting children was implemented. A dedicated procedure was followed in order to provide children with a better understanding of their parent's disease, to alleviate any traumatic experience the visit might cause and to create an environment where mutual confidence would reign. After 2 years, each visiting child, patient, accompanying parent and the nursing staff were directly questioned using a specifically designed questionnaire. The daily lives of the staff, children, families and patients themselves appeared to be dramatically improved, even in the most difficult medical situations. Based on these promising results, the new policy has definitively been adopted in our unit. We propose that children ought to be allowed to visit a parent in the ICU and that this policy warrants evaluation in other types of units.

[Standards, Options and Recommendations 2005 for a good practice in enteral nutrition in oncology (summary report.)]. / Recommandations pour la pratique clinique: Standards, Options et Recommandations 2005. Bonnes pratiques pour la prise en charge diététique en cancérologie: la nutrition entérale (rapport abrégé). Validation du rapport original: avril 2005.

CONTEXT: The "Standards, Options and Recommendations" (SOR) project, which started in 1993, is a collaboration between the French Federation of Cancer Centers (FNCLCC), the 20 French Regional Cancer Centers, and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. OBJECTIVE: To develop good practice guidelines for a good practice of enteral nutrition in oncology, in collaboration with three French learned societies involved in this area. METHOD: The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts who define the CPGs according to the definitions of the Standards, Options and Recommendations project. Once the guideline has been defined, the document is submitted for review by independent reviewers. RESULTS: The good practices suggested in the document approach seven topics: indications and counter-indications, conditions of the installation of the enteral nutrition, monitoring, prevention of complications, education of the patient, specificities of enteral nutrition in children and at home. In the setting of enteral nutrition, feeding tubes, type of insertion, enteral nutrition products, material and techniques of administration are described as well as the criteria permitting their selection.

[Meningitis caused by Enterococcus faecalis during disseminated anguilluliasis]. / Méningite à Enterococcus faecalis au cours d'une anguillulose disséminée.

INTRODUCTION: Disseminated anguilluliasis is a serious disease requiring early diagnosis and treatment. The occurrence of bacterial complications, especially meningeal, is generally due to Gram-negative bacteria from the gastrointestinal tract. CASE: A 52-year-old man from Guadeloupe, treated for T-lymphoma during the previous year by polychemotherapy, was hospitalized for meningitis. Culture of the cerebrospinal fluid and the bronchoalveolar lavage both showed Enterococcus faecalis. Strongyloides stercoralis were also found in the stool and bronchoalveolar lavage. Outcome under treatment was favorable. DISCUSSION: This case reminds us of the usefulness of presumptive routine ivermectin treatment for all patients exposed to any immunosuppression treatment and ever having lived in a tropical area and thus possibly infected by chronic but silent anguilluliasis, even in the absence of parasitological certainty.

Outcome of critically ill allogeneic hematopoietic stem-cell transplantation recipients: a reappraisal of indications for organ failure supports.

PURPOSE: Because the overall outcome of critically ill hematologic patients has improved, we evaluated the short-term and long-term outcomes of the poor risk subgroup of allogeneic hematopoietic stem-cell transplantation (HSCT) recipients requiring admission to the intensive care unit (ICU). PATIENTS AND METHODS: This was a retrospective multicenter study of allogeneic HSCT recipients admitted to the ICU between 1997 and 2003. RESULTS: Two hundred nine critically ill allogeneic HSCT recipients were included in the study. Admission in the ICU occurred during the engraftment period (< or = 30 days after transplantation) for 70 of the patients and after the engraftment period for 139 patients. The overall in-ICU, in-hospital, 6-month, and 1-year survival rates were 48.3%, 32.5%, 27.2%, and 21%, respectively. Mechanical ventilation was required in 122 patients and led to a dramatic decrease in survival rates, resulting in in-ICU, in-hospital, 6-month, and 1-year survival rates of 18%, 15.6%, 14%, and 10.6%, respectively. Mechanical ventilation, elevated bilirubin level, and corticosteroid treatment for the indication of active graft-versus-host disease (GVHD) were independent predictors of death in the whole cohort. In the subgroup of patients requiring mechanical ventilation, associated organ failures, such as shock and liver dysfunction, were independent predictors of death. ICU admission during engraftment period was associated with acceptable outcome in mechanically ventilated patients, whereas patients with late complications of HSCT in the setting of active GVHD had a poor outcome. CONCLUSION: Extensive unlimited intensive care support is justified for allogeneic HSCT recipients with complications occurring during the engraftment period. Conversely, initiation or maintenance of mechanical ventilation is questionable in the setting of active GVHD.

Risk factors for Gram-negative bacterial infections in febrile neutropenia.

BACKGROUND AND OBJECTIVES: The objective of this study was to evaluate the risk of Gram-negative bacterial infections in febrile neutropenic patients and to develop a specific risk score. DESIGN AND METHODS: This prospective study included 513 consecutive febrile neutropenic, evaluable patients. Forty-five per cent of the patients were receiving prophylactic gut decontamination, and 6% were receiving prophylactic quinolones at the onset of febrile neutropenia. Data were collected from the onset of febrile neutropenia until 30 days later. Risk factors for Gram-negative bacterial infection were identified by comparing baseline characteristics of patients with and without Gram-negative bacterial infection. Independent risk factors in multivariate analysis were used to build a predictive score for Gram-negative bacterial infection. RESULTS: The prevalence of Gram-negative bacterial infection was 55/513 (10.7%). Gram-negative bacterial infections were due to E. coli in 30 patients, other enterobacteriae in 11, Pseudomonas spp. in 13, and Salmonella spp. in one. In multivariate analysis, the occurrence of Gram-negative bacterial infection was significantly associated with age > 45 years (p=0.009), recent administration of betalactams (p=0.04), chills (p=0.0001), urinary symptoms (p=0.01), and absence of gut decontamination with both colimycin and aminoglycosides (p=0.001). The relative risk for Gram-negative bacterial infection was 4.4, 12.6, 25.4 and 100 in the presence of 1, 2, 3 , or at least 4 parameters, respectively. The performances of our scoring system and the post-test probabilities according to different prevalence rates of Gram-negative bacterial infection (0.05, 0.10, 0.20) lead us to propose a Gram-negative risk score of >or=3 as indicating a high probability of Gram-negative bacterial infection. INTERPRETATION AND CONCLUSIONS: Our scoring system identifies patients with a high probability of Gram-negative bacterial infection as those with a score >or=3. If confirmed in a validation set, this score could be considered in the choice of the first-line antibiotics in febrile neutropenic patients.

Indwelling time and risk of infection of dialysis catheters in critically ill cancer patients.

OBJECTIVE: Despite the lack of evidence to support routine scheduled replacement of dialysis catheters (DCs) this practice continues to be widely used in many intensive care units (ICUs). This study evaluated whether additional risks of catheter-related infection (CRI) are incurred with a conservative attitude in critically ill cancer patients. DESIGN AND SETTING: Prospective, observational study over a 14-month period in a 15-bed medicosurgical unit in a comprehensive cancer center. PATIENTS: Seventy-nine double-lumen DCs were evaluated in 47 patients. Incidence rates of infection per 1000 days of catheter use were examined over 7-day periods. MEASUREMENTS AND RESULTS: The mean indwelling time was 6.9+/-5.5 days. Twelve DCs (15.2%) were removed for suspected CRI. Catheter-tip cultures remained negative in 74 cases (93.7%). Overall, one bacteremic CRI, two colonization episodes, and two contaminations were diagnosed, leading to DC colonization and DC-related bacteremia incidence rates of, respectively, 5.4 and 1.8 per 1000 days. When the catheter colonization rate was examined at 7-day intervals, the incidence rate was similar whatever the indwelling time: 5.8, 4.8, and 6.0 per 1000 days, respectively, for the 49 catheters left in place for 7 days or less, 8-14 days (21 DCs), and more than 14 days (9 DCs). The DC colonization incidence rate was similar to that of the 42 short-term catheters inserted during the same period in the same patients (5.9 per 1000 days). CONCLUSIONS: The stable low risk for DC-related infections over time does not support the rationale for scheduled replacement, even in immunocompromised cancer patients.
