RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: The indication of antiseptic-coated catheters remains debated. OBJECTIVE: To test the ability of the new generation of chlorhexidine-silver and sulfadiazine-coated catheters, with enhanced antiseptic coating, to reduce the risk of central venous catheter (CVC)-related infection in ICU patients. DESIGN: Multicentre randomized double-blind trial. PATIENTS AND SETTING: A total of 397 patients from 14 ICUs of university hospitals in France. INTERVENTION: Patients were randomized to receive an antiseptic-coated catheter (ACC) or a standard non-coated catheter (NCC). MEASUREMENTS: Incidence of CVC-related infection. RESULTS: Of 367 patients having a successful catheter insertion, 363 were analysed (175 NCC and 188 ACC). Patients had one (NCC=162, ACC=180) or more (NCC=13, ACC=11) CVC inserted. The two groups were similar for insertion site [subclavian (64 vs 69)] or jugular (36 vs 31%)], and type of catheters (single-lumen 18 vs 18%; double-lumen 82 vs 82%), and mean (median) duration of catheterisation [12.0+/-11.7 (9) vs 10.5+/-8.8 (8) days in the NCC and ACC groups, respectively]. Significant colonisation of the catheter occurred in 23 (13.1%) and 7 (3.7%) patients, respectively, in the NCC and ACC groups (11 vs 3.6 per 1000 catheter-days; p=0.01); CVC-related infection (bloodstream infection) occurred in 10 (5) and 4 (3) patients in the NCC and CC groups, respectively (5.2 vs 2 per 1000 catheter days; p=0.10). CONCLUSIONS: In the context of a low baseline infection rate, ACC were associated with a significant reduction of catheter colonisation and a trend to reduction of infection episodes, but not of bloodstream infection.

RESUMEN

The immediate metabolic response to a septic challenge is probably adaptive, meaning that nutritional interference, mainly via the parenteral route, during this early phase of instability can do more harm than good. During the later phases, a gradual increase in enteral nutrition, at the expense of parenteral nutrition, combined with the administration of nutraceuticals such as glutamine and omega-3 fatty acids, can counteract wasting and modulate the complex inflammatory response and immunosuppression associated with sepsis. In these times of scarce resources, there is an urgent need to clearly document the efficacy of immuno/pharmaconutrients, individually and in combination, enterally or parenterally, before proposing them for routine management of septic patients in the intensive care unit.

RESUMEN

CONTEXT: The "Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the Federation of French Cancer Centers (FNCLCC), the 20 French cancer centers and specialists from French public university and general hospitals and private clinics. Its main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. OBJECTIVES: To develop, according to the definitions of the Standards, Options and Recommendations, clinical practice guidelines for nutritional support in bone marrow transplant patients. METHODS: Data were identified by searching Medline , web sites and the personal reference lists of members of the expert groups, then submitted for review to 75 independent reviewers. RESULTS: The main recommendations for nutritional support in bone marrow transplant patients are: 1) Nutritional evaluation and monitoring may be proposed to bone-marrow transplant recipients (options). 2) Nutritional evaluation consists of body weight assessment and percent weight loss evaluation (standard, expert agreement). 3) Nutritional monitoring should include daily weight monitoring, clinical monitoring of hydration and assessment of daily dietary intake (standard, expert agreement). 4) Artificial nutrition is recommended in immuno-suppressed bone marrow transplant patients. This is not systematically indicated in other situation (standard). 5) Artificial nutrition, intravenous hydration and oral nutrition can be proposed to bone-marrow transplant recipients (option). 6) There is no standard modality for artificial nutrition (level of evidence B 1). Exclusive enteral or parenteral nutrition and enteral plus parenteral nutrition may be proposed to bone-marrow transplant patients (options). 7) Lipid intake representing up to 30% of the non-protein caloric intake should be supplied to patients undergoing bone marrow transplantation (standard, level of evidence B1). 8) Oral supplementation with nitrogen substrates or glutamine is not recommended. Parenteral glutamine supplementation may be proposed (option).

RESUMEN

IDENTIFICATION OF LOW-RISK PATIENTS: These patients exhibit a low probability of dying (risk equal or lesser than 1%) and of developing major complications (risk to the order of 5%). A clinical model developed by Talcott et al. considers at low risk patients at home when the fever starts, without severe co-morbidity and in whom the neoplasia is under control. A prognostic score was established by the MASCC (Multinational Association for Supportive Care in Cancer); it is based on objectively weighted and selected variables. In comparison, the Talcott's classification appears more restrictive (2.5-fold less patients at low risk) but also that it supplies greater safety. IDENTIFICATION OF HIGH-RISK PATIENTS: All the severity scores used in intensive care have their limits. However, the repeated calculation of severity scores (at 48 and 72 hours) might lead to an improvement in their predictive value. The number of organ dysfunction could also be used because the latter provides supplementary clinical information and hence the development of organ dysfunction scores over the past few Years. For febrile neutropenic patients other than in intensive care, the interest of the severity scores and organ dysfunction scores appears limited.

RESUMEN

Whether they are the first sign of cancer or aggravate the evolution of a neoplasm already known and treated, renal, hepatic and cardiac failure constitute a vital threat for a patient with cancer and often justifies an admission to intensive care. If the clinical picture can be considered similar in all respects to that of other patients, the neoplasia and its treatments are often responsible for etiological, diagnostic, prognostic and therapeutic particularities that merit being known. So it is in nephrology with the glomerulopathies and thrombotic microangiopathy, in hepatology with veno-occlusive disease and graft versus host rejection, in cardiology with aplastic septic shock, anthracycline myocardial toxicity, cardiac tamponade... the list is far from being exhaustive. We have attempted to clarify certain of these specifities and the diagnostic and therapeutic approach adapted to these situations that are too often the source of errors with serious consequences.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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).
