Validation of a 15-item Care-related Regret Coping Scale for Health-care Professionals (RCS-HCP).
J Occup Health
PUBLISHED: 09-13-2014
Show Abstract
Hide Abstract
Objectives: Coping with difficult care-related situations is a common challenge for health-care professionals. How these professionals deal with the regrets they may experience following one of the many decisions and interventions they must make every day can have an impact on their own health and quality of life, and also on their patient care practices. To identify professionals most at need for extra support, development and validation of a tool measuring coping style are needed. Methods: We performed a survey of physicians and nurses of a French-speaking University hospital; 469 health-care professionals responded to the survey, and 175 responded to the same survey one-month later. Regret was assessed with the regret coping scale developed for this study, self-report questions on the frequency of regretted situations and the intensity of regret. Construct validity was assessed using measures of health-care professionals' quality of life (including job and life satisfaction, and self-reported health) as well as sleep problems and depression. Results: Based on factor analysis and item response analysis, the initial 31-item scale was shortened to 15 items, which measured three types of strategies: problem-focused strategies (i.e., trying to find solutions, talking to colleagues) and two types of emotion-focused strategies, A (i.e., self-blame, rumination) and B (e.g., acceptance, emotional distance). All subscales showed high internal consistency (?>0.85). Overall, as expected, problem-focused and emotion-focused B strategies correlated with higher quality of life, fewer sleep problems and less depression, and emotion-focused A strategies showed the opposite pattern. Conclusions: The regret coping scale (RCS-HCP) is a valid and reliable measure of coping abilities of hospital-based health-care professionals.

Prognostic ROC curves: a method for representing the overall discriminative capacity of binary markers with right-censored time-to-event endpoints.
Epidemiology
PUBLISHED: 07-31-2014
Show Abstract
Hide Abstract
Survival curves are a popular tool for representing the association between a binary marker and the risk of an event. The separation between the survival curves in patients with a positive marker (high-risk group) and a negative marker (low-risk group) reflects the prognostic ability of the marker. In this article, we propose an alternative graphical approach to represent the discriminative capacity of the marker-a receiver operating characteristic (ROC) curve, tentatively named prognostic ROC curve-obtained by plotting 1 minus the survival in the high-risk group against 1 minus the survival in the low-risk group. The area under the curve corresponds to the probability that a patient in the low-risk group has a longer lifetime than a patient in the high-risk group. The prognostic ROC curve provides complementary information compared with survival curves. However, when the survival functions do not reach 0, the prognostic ROC curve is incomplete. We show how a range of possible values for the area under the curve can be derived in this situation. A simulation study is performed to analyze the accuracy of this methodology, which is also illustrated by applications to the survival of patients with brain metastases and survival of kidney transplant recipients.

N-acetylcysteine does not prevent contrast nephropathy in patients with renal impairment undergoing emergency CT: a randomized study.
BMC Nephrol
PUBLISHED: 05-09-2013
Show Abstract
Hide Abstract
BACKGROUND: Patients admitted to the emergency room with renal impairment and undergoing a contrast computed tomography (CT) are at high risk of developing contrast nephropathy as emergency precludes sufficient hydration prior to contrast use. The value of an ultra-high dose of intravenous N-acetylcysteine in this setting is unknown. METHODS: From 2008 to 2010, we randomized 120 consecutive patients admitted to the emergency room with an estimated clearance lower than 60 ml/min/1.73 m2 by MDRD (mean GFR 42 ml/min/1.73 m2) to either placebo or 6000 mg N-acetylcysteine iv one hour before contrast CT in addition to iv saline. Serum cystatin C and creatinine were measured one hour prior to and at day 2, 4 and 10 after contrast injection. Nephrotoxicity was defined either as 25% or 44 mumol/l increase in serum creatinine or cystatin C levels compared to baseline values. RESULTS: Contrast nephrotoxicity occurred in 22% of patients who received placebo (13/58) and 27% of patients who received N-acetylcysteine (14/52, p = 0.66). Ultra-high dose intravenous N-acetylcysteine did not alter creatinine or cystatin C levels. No secondary effects were noted within the 2 groups during follow-up. CONCLUSIONS: An ultra-high dose of intravenous N-acetylcysteine is ineffective at preventing nephrotoxicity in patients with renal impairment undergoing emergency contrast CT.Trial registration: The study was registered as Clinical trial (NCT01467154).

Impact of Advance Directives and a Health Care Proxy on Doctors Decisions: A Randomized Trial.
J Pain Symptom Manage
PUBLISHED: 03-02-2013
Show Abstract
Hide Abstract
CONTEXT: Advance directives or proxy designations are widely recommended, but how they affect doctors decision making is not well known. OBJECTIVES: The aim of this study was to quantify the influence of advance directives and proxy opinions on doctors decisions. METHODS: We mailed to all the generalists and internists in French-speaking Switzerland (N = 1962) three vignettes describing difficult decisions involving incapacitated patients. In each case, the advance directive requested that further care be withheld. One vignette tested the impact of a written advance directive vs. a proxy. Another compared the impact of a handwritten directive vs. a formalized document. The third vignette compared the impact of a family member vs. a doctor as a proxy. Each vignette was prepared in three or four versions, including a control version in which no directive or proxy was present. Vignettes were randomly allocated to respondents. We used logistic regression to predict the decision to forgo a medical intervention. RESULTS: Compared with the control condition, the odds of forgoing a medical intervention were increased by the written advance directive (odds ratio [OR] 7.3; P < 0.001), the proxy (OR 7.9; P < 0.001), and the combination of the two (OR 35.7; P < 0.001). The handwritten directive had the same impact (OR 13.3) as the formalized directive (OR 13.8). The effect of proxy opinion was slightly stronger when provided by a doctor (OR 11.3) rather than by family (OR 7.8). CONCLUSION: Advance directives and proxy opinions are equally effective in influencing doctors decisions, but having both has the strongest effect. The format of the advance directive and the identity of the proxy have little influence on decisions.

Hide Abstract
There are very limited data suggesting a benefit for second-line chemotherapy in advanced gastric cancer. Therefore, the number of patients who receive further treatment after failure of first-line chemotherapy varies considerably, ranging from 14% to 75%. In the absence of a demonstrated survival benefit of second-line chemotherapy, appropriate selection of patients based on survival predictors is essential. However, no clinico-pathologic parameters are currently widely adopted in clinical practice. We looked exclusively at Caucasian patients with metastatic gastric cancer treated with second-line chemotherapy to see if we could establish prognostic factors for survival.

Chest physiotherapy using passive expiratory techniques does not reduce bronchiolitis severity: a randomised controlled trial.

Hide Abstract
Chest physiotherapy (CP) using passive expiratory manoeuvres is widely used in Western Europe for the treatment of bronchiolitis, despite lacking evidence for its efficacy. We undertook an open randomised trial to evaluate the effectiveness of CP in infants hospitalised for bronchiolitis by comparing the time to clinical stability, the daily improvement of a severity score and the occurrence of complications between patients with and without CP. Children <1 year admitted for bronchiolitis in a tertiary hospital during two consecutive respiratory syncytial virus seasons were randomised to group 1 with CP (prolonged slow expiratory technique, slow accelerated expiratory flow, rarely induced cough) or group 2 without CP. All children received standard care (rhinopharyngeal suctioning, minimal handling, oxygen for saturation ?92%, fractionated meals). Ninety-nine eligible children (mean age, 3.9 months), 50 in group 1 and 49 in group 2, with similar baseline variables and clinical severity at admission. Time to clinical stability, assessed as primary outcome, was similar for both groups (2.9?±?2.1 vs. 3.2?±?2.8 days, P?=?0.45). The rate of improvement of a clinical and respiratory score, defined as secondary outcome, only showed a slightly faster improvement of the respiratory score in the intervention group when including stethoacoustic properties (P?=?0.044). Complications were rare but occurred more frequently, although not significantly (P?=?0.21), in the control arm. In conclusion, this study shows the absence of effectiveness of CP using passive expiratory techniques in infants hospitalised for bronchiolitis. It seems justified to recommend against the routine use of CP in these patients.

PUBLISHED: 05-18-2010

Hide Abstract
It is generally believed that culturally competent clinical practice depends in part on the development of positive attitudes toward the care of immigrant patients. However, few tools exist to measure such attitudes in physicians. The authors operationalized culturally competent attitudes to include a high level of interest in caring for immigrant patients, an acceptance of the responsibility of doctors and hospitals to adapt to immigrant patients needs, and the opinion that understanding the patients psychosocial context is particularly important when caring for immigrant patients. The authors then assessed these attitudes and opinions among a sample of 619 Geneva doctors and medical students using a self-administered questionnaire and explored their association to respondents personal characteristics and professional experience. The authors found that both personal characteristics and professional experience were associated with attitudes toward caring for immigrant patients. In particular, the perceived importance of understanding the psychosocial context when caring for migrants was higher among medical students, women, Swiss nationals, those with greater interest in caring for immigrant patients and those who had received training in cultural competence. However, it is unclear whether cultural competence training and clinical context lead to the development of more positive attitudes or whether medical students and physicians who already have positive attitudes are more likely to participate in such training.

Medical fee schedules are controversial. In this paper we examine the reasons that justify the imposition of fee schedules in the presence of a socially financed health insurance system, and examine the ways of constructing a medical fee schedule. The weakness of fee-for-service tariffs is that they do not allow a control of health care costs if the volume of services is unchecked. Current solutions to this problem--audit of doctors average cost per case, freeze on new medical practices, or the insurers discretion in choosing the doctors they reimburse--have multiple drawbacks. Alternatives to fee-for-service payment--such as flat fees, or payment based on the quality of medical services--are discussed.

Towards an International Classification for Patient Safety: the conceptual framework.
Int J Qual Health Care

Show Abstract
Hide Abstract
Global advances in patient safety have been hampered by the lack of a uniform classification of patient safety concepts. This is a significant barrier to developing strategies to reduce risk, performing evidence-based research and evaluating existing healthcare policies relevant to patient safety. Since 2005, the World Health Organizations World Alliance for Patient Safety has undertaken the Project to Develop an International Classification for Patient Safety (ICPS) to devise a classification which transforms patient safety information collected from disparate systems into a common format to facilitate aggregation, analysis and learning across disciplines, borders and time. A drafting group, comprised of experts from the fields of patient safety, classification theory, health informatics, consumer/patient advocacy, law and medicine, identified and defined key patient safety concepts and developed an internationally agreed conceptual framework for the ICPS based upon existing patient safety classifications. The conceptual framework was iteratively improved through technical expert meetings and a two-stage web-based modified Delphi survey of over 250 international experts. This work culminated in a conceptual framework consisting of ten high level classes: incident type, patient outcomes, patient characteristics, incident characteristics, contributing factors/hazards, organizational outcomes, detection, mitigating factors, ameliorating actions and actions taken to reduce risk. While the framework for the ICPS is in place, several challenges remain. Concepts need to be defined, guidance for using the classification needs to be provided, and further real-world testing needs to occur to progressively refine the ICPS to ensure it is fit for purpose.

Osteotome sinus floor elevation with and without grafting material in the severely atrophic maxilla. A 1-year prospective randomized controlled study.
Clin Oral Implants Res
Show Abstract
Hide Abstract
OBJECTIVES: (1) To measure and compare endo-sinus bone levels around implants randomly placed with an osteotome sinus floor elevation (OSFE) procedure in grafted (control) and non-grafted (test) sinuses, (2) to evaluate the OSFE efficacy with short, tapered, and chemically modified hydrophilic surfaced implants in extremely atrophic maxillae, (3) to show that fused corticals may constitute a complication risk. MATERIAL AND METHODS: The TE(®) SLActive 8 mm-long implants (Straumann AG) were placed using an OSFE procedure in 4 mm or less of bone height. Healing time before prosthetic rehabilitation was 10 weeks. One year after implant placement, bone levels were measured on standardized periapical radiographs. RESULTS: Thirty-seven (17 tests, 20 controls) implants were placed in 12 patients with a mean maxillary residual bone height (RBH) of 2.4 ± 0.9 mm. Before loading, two control implants failed (RBH 1.4 and 1.2 mm); two others rotated at loading (one test, RBH 0.9 mm; one control, RBH 1.5 mm) but were uneventfully loaded after three additional months of healing. These adverse events and complications occurred when implants were placed in merged corticals. Endo-sinus bone gain was 3.9 ± 1.0 and 5.0 ± 1.3 mm for the test and control groups (P = 0.003). The 1-year success rate was 100% and 90%, respectively (P = 0.49). CONCLUSION: Although more bone is gained when grafting material is used, this may not be required to promote endo-sinus bone gain. The OSFE procedure with or without grafting material could be efficient when the RBH is ?4 mm. However, when both corticals merged, the risk of complication could increase.

A model for dropout assessment of candidates with or without hepatocellular carcinoma on a common liver transplant waiting list.
Hepatology
Show Abstract
Hide Abstract
In many countries, the allocation of liver grafts is based on the Model of End-stage Liver Disease (MELD) score and the use of exception points for patients with hepatocellular carcinoma (HCC). With this strategy, HCC patients have easier access to transplantation than non-HCC ones. In addition, this system does not allow for a dynamic assessment, which would be required to picture the current use of local tumor treatment. This study was based on the Scientific Registry of Transplant Recipients and included 5,498 adult candidates of a liver transplantation for HCC and 43,528 for non-HCC diagnoses. A proportional hazard competitive risk model was used. The risk of dropout of HCC patients was independently predicted by MELD score, HCC size, HCC number, and alpha-fetoprotein. When combined in a model with age and diagnosis, these factors allowed for the extrapolation of the risk of dropout. Because this model and MELD did not share compatible scales, a correlation between both models was computed according to the predicted risk of dropout, and drop-out equivalent MELD (deMELD) points were calculated.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
