RESUMO

PURPOSE: Referrals to the Emergency Department can be distressing to patients with advanced cancer and may be a non-optimizing health care service. We aimed to describe the appropriateness and potential avoidability of Emergency Department referrals in a tertiary cancer care center where only physician referrals are allowed. METHODS: We prospectively reviewed the electronic medical charts of patients consecutively checked into the Emergency Department in August 2015. The appropriateness of referrals was assessed using a nationally validated classification (Classification Clinique des Malades aux Urgences) and local criteria. Potentially avoidable referrals were assessed using international classifications (Institute for Healthcare Improvement State Action on Avoidable Rehospitalizations diagnostic tool according to Kosecoff's criteria) and local criteria. RESULTS: We included 500 referrals related to 423 patients. The mean age was 59 years, and 74% of cancers were progressive. The referrals were appropriate in 61% of cases. They were deemed potentially avoidable "with a high likelihood" in 33.4% (CI95% [29.3-37.5]) of cases, potentially avoidable "with a moderate likelihood" in 14.4% (CI95% [11.3-17.5]) of cases, and "non-avoidable" in 52% (CI95% [47.6-56.4]) of cases. Opportunities to avoid referrals after an index stay involved this hospital stay or discharge process in 66 cases (28%), the follow-up period in 59 cases (25%), or both in 66 cases (28%). CONCLUSIONS: Potentially avoidable ED referrals are common in patients with cancer. These potentially avoidable ED referrals underline the importance of several domains of care coordination.

RESUMO

OBJECTIVE: Most studies showed no or little effect of pay-for-performance (P4P) programs on different outcomes. In France, the P4P program IFAQ was generalized to all acute care hospitals in 2016. A pilot study was launched in 2012 to design, implement and assess this program. This article aims to assess the immediate impact of the 2012-14 pilot study. DESIGN AND SETTING: From nine process quality indicators (QIs), an aggregated score was constructed as the weighted average, taking into account both achievement and improvement. Among 426 eligible volunteer hospitals, 222 were selected to participate. Eligibility depended on documentation of QIs and results of hospital accreditation. Hospitals with scores above the median received a financial reward based on their ranking and budget. Several characteristics known to have an influence on P4P results (patient age, socioeconomic status, hospital activity, casemix and location) were used to adjust the models. INTERVENTION: To assess the effect of the program, comparison between the 185 eligible selected hospitals and the 192 eligible not selected volunteers were done using the difference-in-differences method. RESULTS: Whereas all hospitals improved from 2012 to 2014, the difference-in-differences effect was positive but not significant both in the crude (2.89, P = 0.29) and adjusted models (4.07, P = 0.12). CONCLUSION: These results could be explained by several reasons: low level of financial incentives, unattainable goals, too short study period. However, the lack of impact for the first year should not undermine the implementation of other P4P programs. Indeed, the pilot study helped to improve the final model used for generalization.

RESUMO

OBJECTIVE: To determine the impact on hospital ranking of different aggregation methods when creating a composite score from a set of quality indicators relating to a single clinical condition. DESIGN: The analysis was based on 14966 medical records taken from all French hospitals that treated over 30 patients with acute myocardial infarction in 2008 (n=275). Five quality indicators measuring the quality of care delivered to patients with acute myocardial infarction at hospital discharge were aggregated by 5 methods issued from a variety of activity sectors (indicator average, all-or-none, budget allocation process, benefit of the doubt, and unobserved component model). MAIN OUTCOME MEASURES: Each aggregation method was used to rank hospitals into 3 categories depending on the position of the 95% confidence interval of the composite score relative to the overall mean. Variations in rank according to method were estimated using weighted κ coefficients. RESULTS: Agreement between methods ranged from poor (κ=0.20) to almost perfect (κ=0.84). A change of method led to a change in rank for 71% (196 of 275) of hospitals. Only 14 of 121 hospitals which were ranked top and 20 of 118 which were ranked bottom, by at least 1 of the 5 methods, held their rank on a switch to the 4 other methods. CONCLUSION: Hospital ranking varied widely according to 5 aggregation methods. If one method has to be chosen, for instance for reporting to governments, regulatory agencies, payers, health care professionals, and the public, it is necessary to provide its rationale and characteristics, and information on score uncertainty.

RESUMO

BACKGROUND: Coordination within hospitals is a major attribute of medical care and influences quality of care. This study tested the validity of 3 indicators covering two key aspects of coordination: the transfer of written information between professionals (medical record content, radiology exam order) and the holding of multidisciplinary team meetings during treatment planning. METHODS: The study was supervised by the French health authorities (COMPAQH project). Data for the three indicators were collected in a panel of 30 to 60 volunteer hospitals by 6 Clinical Research Assistants. The metrological qualities of the indicators were assessed: (i) Feasibility was assessed using a grid of 19 potential problems, (ii) Inter-observer reliability was given by the kappa coefficient () and internal consistency by Cronbach's alpha test, (iii) Discriminatory power was given by an analysis of inter-hospital variability using the Gini coefficient as a measure of dispersion. RESULTS: Overall, 19281 data items were collected and analyzed. All three indicators presented acceptable feasibility and reliability (, 0.59 to 0.97) and showed wide differences among hospitals (Gini, 0.08 to 0.11), indicating that they are suitable for making comparisons among hospitals. CONCLUSION: This set of 3 indicators provides a proxy measurement of coordination. Further research on the indicators is needed to find out how they can generate a learning process. The medical record indicator has been included in the French national accreditation procedure for healthcare organisations. The two other indicators are currently being assessed for inclusion.

RESUMO

Despite a wide implementation of pay-for-performance (P4P) programs, evidence on their impact in hospitals is still limited. Our objective was to assess the implementation of the French P4P pilot program (IFAQ1) across 222 hospitals. The study consisted of a questionnaire among four leaders in each enrolled hospital, combined with a qualitative analysis based on 33 semi-structured interviews conducted with staff in four participating hospitals. For the questionnaire results, descriptive statistics were performed and responses were analyzed by job title. For the interviews, transcripts were analysed using coding techniques. Survey results showed that leaders were mostly positive about the program and reported a good level of awareness, in contrast to the frontline staff, who remained mostly unaware of the program's existence. The main barriers were attributed to lack of clarity in program rules, and to time constraints. Different strategies were then suggested by leaders. The qualitative results added further explanations for low program adoption among hospital staff, so far. Ultimately, although paying for quality is still an intuitive approach; gaps in program awareness within enrolled hospitals may pose an important challenge to P4P efficacy. Implementation evaluations are therefore necessary for policymakers to better understand P4P adoption processes among hospitals.

RESUMO

BACKGROUND: Intensive care unit (ICU) admission of adults with cystic fibrosis (CF) is controversial because of poor outcome. This appraisal needs re-evaluation following recent changes in both CF management and ICU daily practice. Objectives were to determine long-term outcome of adults with CF admitted in ICU and to identify prognostic factors. METHODS: Retrospective multicenter study of 60 ICU hospitalizations for 42 adult CF patients admitted between 2000 and 2003. Reason for ICU admission, ventilatory support provided and one-year survival were recorded. Multiple logistic analysis was used to determine predictors of mortality. RESULTS: Prior to ICU admission, all patients (mean age 28.1 +/- 8 yr) had a severe lung disease (mean FEV1 28 +/- 12% predicted; mean PaCO2 47 +/- 9 mmHg). Main reason for ICU hospitalization was pulmonary infective exacerbation (40/60). At admission, noninvasive ventilation was used in 57% of cases and was successful in 67% of patients. Endotracheal intubation was implemented in 19 episodes. Overall ICU mortality rate was 14%. One year after ICU discharge, 10 of the 28 survivors have been lung transplanted. Among recognized markers of CF disease severity, only the annual FEV1 loss was associated with a poor outcome (HR = 1.47 [1.18-1.85], p = 0.001). SAPSII (HR = 1.08 [1.03-1.12], p < 0.001) and endotracheal intubation (HR = 16.60 [4.35-63.34], p < 0.001) were identified as strong independent predictors of mortality. CONCLUSION: Despite advanced lung disease, adult patients with CF admitted in ICU have high survival rate. Endotracheal intubation is associated with a poor prognosis and should be used as the last alternative. Although efforts have to be made in selecting patients with CF likely to benefit from ICU resources, ICU admission of these patients should be considered.

RESUMO

Cerebellar syndromes and radiologic cerebellar atrophy after hyperpyrexia have occasionally been reported, mostly in neuroleptic malignant syndromes, but neuropathologic studies are extremely rare. We studied 3 patients (a 74-year-old woman, a 63-year-old man, and an 80-year-old man) who had heat stroke during heat waves in France. One patient had generalized seizures and died 28 hours after admission. The other patients survived one month and 2 months after admission; both had palatal myoclonus, and in one case, magnetic resonance imaging showed high signal intensity in the cerebral peduncles. The main neuropathology in the 3 cases was severe diffuse loss of Purkinje cells associated with heat shock protein 70 expression by Bergmann glia. In situ end labeling was negative in surviving Purkinje cells, suggesting that the mechanism of neuronal death was not apoptosis. Degeneration of Purkinje cells axons resulted in myelin pallor of the white matter of the folia and of the hilum of the dentate nuclei. DNA internucleosomal breakages were identified by in situ end labeling in the dentate nuclei and centromedian nuclei of the thalamus and were associated with degeneration of the cerebellar efferent pathways: superior cerebellar peduncles, decussation of the superior cerebellar peduncles (Wernekinck commissure), and dentatothalamic tract. These findings suggest that the mechanisms of neuronal death in the dentate nuclei and centromedian nuclei of the thalamus was different from that in Purkinje cells and more likely resulted from deafferentation. Ammon's horn and other areas susceptible to hypoxia were spared. These observations confirm the selective vulnerability of Purkinje cells to heat-induced injury and involvement of the cerebellar efferent pathways in palatal myoclonus.

RESUMO

STUDY OBJECTIVES: To assess incidence, outcome, and early predictors of mortality for patients with primary graft failure (PGF) following lung transplantation (LTx), and to develop an injury severity score able to accurately predict ICU mortality for these patients. DESIGN: Retrospective cohort analysis. SETTING: Two LTx centers in Paris. PATIENTS: Two hundred fifty-nine patients who underwent LTx over a 12-year period. MEASUREMENTS AND RESULTS: One hundred thirty-one patients (50.6%) met PGF criteria: radiographic graft infiltrate within the first 3 days following LTx associated with gas exchange impairment (PaO(2)/fraction of inspired oxygen ratio < 300 mm Hg). This syndrome was associated with an increased duration of mechanical ventilation (9.1 +/- 1 days vs 3.1 +/- 0.6 days, mean +/- SD; p < 0.001) and ICU mortality (29% vs 10.9%; p < 0.01). The patients with PGF were randomly assigned to developmental (n = 85) and validation (n = 46) samples. Using logistic regression analysis, four variables were found associated with ICU mortality in these patients: age, degree of gas exchange impairment, graft ischemic time, and severe early hemodynamic failure. An ischemia/reperfusion injury severity score was derived using these four variables. Model calibration was good in the developmental and validation samples, as was model discrimination (area under receiver operating characteristic curves, 0.93 and 0.85, respectively). CONCLUSION: PGF following LTx is a frequent event, with significant ICU morbidity and mortality. We demonstrate that four simple factors allow prediction of ICU mortality with good accuracy.

RESUMO

OBJECTIVES: Accreditation in France relies on a mandatory 4-year cycle of self-assessment and a peer review of 82 standards, among which 14 focus priority standards (FPS). Hospitals are also required to measure yearly quality indicators (QIs-5 in 2010). On advice given by the accreditation committee of HAS (Haute Autorité en Santé), based on surveyors proposals and relying mostly on compliance to standards, accreditation decisions are taken by the board of HAS. Accreditation is still perceived by hospitals as a burdensome process and a simplification would be welcomed. The hypothesis was that a more limited number of criteria might give sufficient amount of information on hospitals overall quality level, appraised today by accreditation decisions. DESIGN: The accuracy of predictions of accreditation decisions given by a model, Partial Least Square-2 Discriminant Analysis (PLS2-DA), using only the results of FPS and QIs was measured. Accreditation decisions (full accreditation (A), recommendations or reservation (B), remit decision or non-accreditation (C)), results of FPS and QIs were considered qualitative variables. Stability was assessed by leave one out cross validation (LOOCV). SETTING AND PARTICIPANTS: All French 489 acute care organisations (ACO) accredited between June 2010 and January 2012 were considered, 304 of them having a rehabilitation care sector (RCS). RESULTS: Accuracy of prediction of accreditation decisions was good (89% of ACOs and 91% of ACO-RCS well classified). Stability of results appeared satisfactory when using LOOCV (87% of ACOs and 89% of ACO-RCS well classified). Identification of worse hospitals was correct (90% of ACOs and 97% of ACO-RCS predicted C were actually C). CONCLUSIONS: Using PLS2-DA with a limited number of criteria (QIs and FPS) provides an accurate prediction of accreditation decisions, especially for underperforming hospitals. This could support accreditation committees which give advices on accreditation decisions, and allow fast-track handling of 'safe' reports.

RESUMO

BACKGROUND: In acute myocardial infarction, the relationship between volume and quality indicators (QIs) is poorly documented. Through a nationwide assessment of QIs at discharge repeated for 3 years, we aimed to quantify the relationship between volume and QIs in survivors after acute myocardial infarction. METHODS AND RESULTS: Almost all healthcare centers in France participated. Medical records were randomly selected. Data collection was performed by an independent group. QIs for acute myocardial infarction were defined by an expert consensus group as appropriate prescription at discharge of aspirin, clopidogrel, ß-blocker, statin, and an angiotensin-converting enzyme inhibitor in patients with left ventricular ejection fraction <0.40. A composite QI was calculated through the use of the all-or-none method. Volume was classified into 7 categories based on the number of admissions for acute myocardial infarctions in 2008 (centers with <10 acute myocardial infarctions were excluded). Odds ratios adjusted for age and sex with 95% confidence interval for volume categories were calculated by use of logistic regression for each QI. Temporal changes were tested in centers that participated in all 3 campaigns. A total of 46 390 records were examined: 18 159 in 2008, 12 837 in 2009, and 15 394 in 2010. Two hundred ninety-one centers were eligible for the temporal analysis. There was a significant increase between 2008 and 2009 in appropriate prescription of antiplatelet agents, ß-blockers, angiotensin-converting enzyme inhibitor, statins at discharge, and the composite indicator. Similarly, a significant increase was observed between 2009 and 2010 in appropriate prescription of angiotensin-converting enzyme inhibitor and ß-blockers and in the composite QI. Compared with a volume of >300, a significantly lower rate of all QIs was observed in centers with the lowest volume. Odds ratios progressively decreased with increasing volume. Despite a significant increase in the composite QI over the 3 years, a significant relationship persisted between volume and quality of care. CONCLUSIONS: Analysis of QIs at discharge demonstrates the existence of a relationship between volume and appropriate prescriptions at discharge. Centers with the highest volume perform better on quality measures than centers with lower volumes. Temporal analysis over 3 consecutive years confirms this relationship and shows that it persists despite improvement in QIs between 2008 and 2010.

RESUMO

In the past decade, pay-for-performance (P4P) programs in the health care sector have been im-plemented throughout the world. These programs differ in their design, as they have different targets ( hospitals or physicians) and different performance sectors incentivised. P4P has also been introduced to Chinese hospitals re-cently. This article reviews major P4P initiatives (programs of the U. K. , U. S. , France, etc. ) and collects common design factors for analysis ( targets, quality measures, incentive schemes, performance benchmarks, etc. ) . The pros and cons of each design factor are discussed, and some inevitable empirical pitfalls are also reviewed. It is anticipa-ted that such international experiences can provide possible future reference for the Chinese hospital remuneration re-form.

RESUMO

OBJECTIVE: The use of cardiopulmonary bypass (CPB) for lung transplantation (LTx) has been reported previously. This study reports the authors' experience of planned and unplanned use of cardiopulmonary bypass for LTx. DESIGN: Case series. SETTING: A university teaching hospital. PARTICIPANTS: Patients undergoing LTx. INTERVENTIONS: A retrospective analysis of the charts of all patients having undergone LTx over the last 10 years. MEASUREMENTS AND MAIN RESULTS: Among 140 LTx, 23 (16%) were performed with the use of CPB. CPB was planned in 11 cases and unplanned in the 12 other cases. The use of CPB is associated with a longer period of postoperative mechanical ventilation, more pulmonary edema, more blood transfusion requirement, and an increase in postoperative mortality at 48 hours and 1 month. Surgical difficulties related to the dissection of the native left lung and acute right ventricular failure are the main reasons for unscheduled use of CPB. CONCLUSION: Scheduled and unscheduled CPB for LTx are associated with an increased mortality at 1 month and 1 year.

RESUMO

Nocardia farcinica is an emerging pathogen in immunosuppressed patients causing both localized and disseminated infections. Many strains of this species are multidrug-resistant and require long-term antibiotic therapy, and consequently the choice of an oral treatment can be problematic. We report here the first case of successful treatment of N. farcinica brain abscess in a renal transplant recipient with an extended-spectrum fluoroquinolone, moxifloxacin.

RESUMO

RATIONALE: The effect of graft ischemic time on early graft function and long-term survival of patients who underwent lung transplantation remains controversial. Consequently, graft ischemic time has not been incorporated in the decision-making process at the time of graft acceptance. OBJECTIVES: To investigate the relationship between graft ischemic time and (1) early graft function and (2) long-term survival after lung transplantation. MEASUREMENTS AND MAIN RESULTS: The data from 752 patients who underwent single lung transplantation (n = 258), bilateral lung transplantation (n = 247), and heart-lung transplantation (n = 247) in seven French transplantation centers during a 12-year period were reviewed. Independent data quality control was done to ensure the quality of the collected variables. Mean graft ischemic time was 245.8 +/- 96.4 minutes (range 50-660). After adjustment on 11 potential confounders, graft ischemic time was associated with the recipient Pa(O2)/FI(O2) ratio recorded within the first 6 hours and with long-term survival in patients undergoing single or double lung transplantation but not in patients undergoing heart-lung transplantation. The relationship between graft ischemic time and survival appears to be of cubic form with a cutoff value of 330 minutes. These results were unaffected by the preservation fluid employed. CONCLUSIONS: The results of this large cohort of patients suggest a close relationship between graft ischemic time and both early gas exchange and long-term survival after single and double lung transplantation. Such relationship was not found in patients undergoing heart-lung transplantation. The expected graft ischemic time should be incorporated in the decision-making process at the time of graft acceptance.

RESUMO

BACKGROUND: The liberalization of lung-donor criteria and the use of marginal donors have been advocated to face the current shortage of donors in lung transplantation. However, the impact of donor characteristics on the outcome of lung transplantation is still largely unknown. We aimed to determine, on a large cohort of patients, the effect of donors characteristics on short- and long-term outcome of lung transplantation METHODS: Between 1988 and 1998, a total of 785 adult patients underwent single-lung transplantation (n = 270), bilateral-lung transplantation (n = 251), and heart-lung transplantation (n = 264) in 7 centers in France. We constructed several multivariate models to assess the relationship between donor characteristics and early gas exchange, duration of mechanical ventilation, and long-term survival after lung transplantation. RESULTS: Among donor characteristics, donor gas exchange before harvest was found to be significantly associated with recipient early gas exchange, duration of mechanical ventilation, and long-term survival after adjustment for potential confounding variables. Moreover, nonlinear modeling showed a steep increase in the relative risk of death when donor PaO2/FiO2 before harvest was below 350 (hazard ratio 1.43; 95% confidence interval 1.10-1.85; p = 0.01). Donor and recipient sex mismatch were also found to be significantly associated with long-term survival. CONCLUSIONS: Although liberalization of lung-donor criteria may be considered to overcome the shortage of lung donors, our data suggest that the violation of the gas-exchange criterion should be avoided.
