Predictors of the Indefinite Duration Anticoagulation Treatment Strategy In Patients with Cancer Associated Thrombosis

Background: In patients with cancer and acute venous thromboembolism (VTE), current consensus guidelines recommend anticoagulation therapy for an indefinite duration or until the cancer is resolved.Methods and results: Among 1'247 patients with acute VTE enrolled in the Swiss Venous Thromboembolism Registry (SWIVTER) from 18 hospitals, 315 (25%) had cancer of whom 179 (57%) had metastatic disease, 159 (50%) ongoing or recent chemotherapy, and 83 (26%) tumor surgery within 6 months. Patients with cancer were older (66±14 vs. 60±19 years, p<0.001), more often hospitalized at the time of VTE diagnosis (46% vs. 36%, p=0.001), immobile for >3 days (25% vs. 16%, p<0.001), and more often had thrombocytopenia (6% vs. 1%, p<0.001) than patients without cancer. The 30-day rate of VTE-related death or recurrent VTE was 9% in cancer patients vs. 4% in patients without cancer (p<0.001), and the rates of bleeding requiring medical attention were 5% in both groups (p=0.57). Cancer patients received indefinite-duration anticoagulation treatment more often than patients without cancer (47% vs. 19%, p<0.001), and LMWH mono-therapy during the initial 3 months was prescribed to 45% vs. 8%, p<0.001, respectively. Among patients with cancer, prior VTE (OR 4.0, 95%CI 2.0-8.0), metastatic disease (OR 3.0, 95%CI 1.7-5.2), outpatient status at the time of VTE diagnosis (OR 3.8, 95%CI 1.9-7.6), and inpatient treatment (OR 4.4, 95%CI 2.1-9.2) were independently associated with the prescription of indefinite-duration anticoagulation treatment.Conclusions: Less than half of the cancer patients with acute VTE received a prescription for indefinite-duration anticoagulation treatment. Recurrent VTE, metastatic cancer, outpatient VTE diagnosis, and VTE requiring hospitalization were associated with an increased use of this strategy.

Inefficacité de la gestion de l'hyperglycémie du patient hospitalisé: origines et remèdes [The inefficacy of glycemic control in the hospitalized patient: origins and solutions]

La prévalence du diabète peut être estimée entre 20 et 30% parmi les patients en hôpital aigu. Il a été démontré que l'hyperglycémie, même modérée, est associée à une augmentation de la morbi-mortalité hospitalière, tandis que le contrôle glycémique efficace a un impact favorable sur celle-ci. La prise en charge de l'hyperglycémie demeure pourtant largement inefficace hors des soins intensifs, en raison de la persistance d'une pratique inadaptée. Nous développons actuellement un projet de soins destiné à faire changer les pratiques. Pour un contrôle glycémique efficace, une formation des soignants à une gestion basée sur le concept de couverture des besoins en insuline du patient est nécessaire. La démarche doit être intégrée à une approche de type systémique, prenant en compte le contexte dans lequel les soignants évoluent. The hospital inpatient prevalence of diabetes mellitus can be estimated between 20 and 30%. Even moderate hyperglycemia is associated with increased morbidity and mortality in the acute care setting, whereas efficient glycemic control has been shown to improve both of them significantly. Glycemic control however remains largely inefficient outside of the intensive care unit due to the persistance of an inadequate glycemic management practice. We are currently developing a clinical care project aimed at changing this practice. For an efficient glycemic control, a training programme for health care professionals based on the concept of covering the insulin needs of the patient is mandatory. This programme needs to be integrated in a systemic approach, which takes the professionals' context in account.

Process and Outcome Evaluation of the STAR (Sisters Together Achieving Recovery) Program, September, 2010

In July of 2009, the Division of Criminal and Juvenile Justice Planning (CJJP) received Byrne Justice Assistance Grant/American Recovery and Reinvestment Act funding from the Governor’s Office of Drug Control Policy to conduct a process and outcome evaluation of the STAR (Sisters Together Achieving Recovery) program housed at the Iowa Correctional Institution for Women (ICIW) in Mitchellville, Iowa. The STAR Program is a licensed inpatient substance abuse treatment program that utilizes a Therapeutic Community model (TC). All offenders exiting the STAR program between October 1, 2004 and June 30, 2008 were included in the study (n=173). A comparison sample was drawn of offenders exiting the ICIW during the same release time frame with identified but untreated substance abuse needs (n= 173). March 31, 2010 was designated as the cut-off date for the study. This yielded an average post-program follow-up time of 3.1 years. The STAR group was further divided into two groups by time of program exit. Participants exiting the program between October 1, 2004 and June 30, 2006 were designated as STAR 1 (n=78) and those exiting the program between July 1, 2006 and June 30, 2008 were designated as STAR 2 (n=95). In order to have comparable tracking time between STAR groups, tracking time for STAR 1 concluded July 31, 2008. This yielded an average post release follow-up time of 2.4 years for both groups. Demographic, Program, Intervention, and Outcome data were examined. Comparisons were made between groups as well as categories of participation.

Anorexie mentale et boutimie: I'expérience vaudoise d'une prise en charge interdisciplinaire [Anorexia and bulimia: the canton of Vaud's experience of an interdisciplinary approach].

As psychiatric disorders attacking the body, anorexia and bulimia may have severe psychological, physical and social consequences, often requiring a long-standing interdisciplinary, coordinated and individualized approach. Recently the canton of Vaud has initiated and developed an interinstitutional structure--between the University Hospital (CHUV) and the hospitals of the Northern region of the canton (eHnv)--for the care of patients suffering from eating disorders. This structure, allowing the above mentioned approach for the treatment of eating disorders, consists of an outpatient facility located in the CHUV and an inpatient unit in the hospital of Saint Loup of the eHnv. Within this structure, the general practitioner plays a crucial role in the prevention of the chronification of these disorders by means of their early detection and management.

Prevalence, incidence and indications of hypno-sedative treatments in hospitalized patients aged 75 and older

Introduction Sleep impairment is a common problem in older persons and is associated with adverse health and economic consequences. The most prescribed hypnosedatives in Switzerland are benzodiazepines, benzodiazepine-like hypnosedatives and clomethiazole. In the elderly persons, these medications have been associated with decreased cognitive performance, an increased risk of addiction and an increased risk of falls. The main aim of this study was to determine the prevalence, incidence and indications of hypnosedative prescriptions in older in-patients admitted to a Swiss university hospital. Furthermore, we planned to investigate the possible relationship between hypnosedatives' prescription and patients' falls during the hospital stay and we compared the prevalence of hypnosedative drugs' prescribing between geriatric and non-geriatric clinical wards.Materials & Methods This observational study included all patients aged 75 years or older admitted to a Swiss university hospital for 24 h or more. Prescription-related data were recorded every day for 26 consecutive days in the two geriatric wards, and twice, a week apart, in three non-geriatric wards.Results A total of 204 patients (mean age 84.7 ± 0.7 years, 66% women) were included. The prevalence of hypnosedative drugs prescription was 73% and the incidence was 28% on the two geriatric wards. The most common indications for a prescription on geriatric wards was insomnia (51%), followed by continuation of usual treatment (12%). The most frequently prescribed hypnosedative drug was clomethiazole (64% of the patients), followed by lorazepam (11%). We were not able to demonstrate any significant correlation between the number of hypnosedative drugs prescribed and the number of falls during hospital stay. The prevalence of hypnosedative drugs prescriptions was similar between geriatric and non-geriatric wards. The proportion of patients treated by at least one hypnosedative increased between hospital admission (32%) and discharge (45%).Discussions, Conclusion This study reveals a high prevalence of hypnosedative prescription in medical in-patients aged 75 years or older. Main indication was insomnia and the most frequently prescribed hypnosedative molecule was clomethiazole. Prescription incidence was also very high and the proportion of patients being prescribed a hypnosedative increased during hospital stay. Systematic interventions need to be integrated in order to reduce elderly inpatient exposure to treatments that are associated with adverse health outcomes.Conference information: ESCP 40th International Symposium on Clinical Pharmacy.

Predictors of physiotherapy and occupational therapy use two years after a vocational rehabilitation for orthopaedic trauma

Introduction.- Health care utilization is an important field of our economy. Nevertheless a minority of cases induce the majority of costs. For instance, in the setting of accident insurance, the most expensive 5% of all injured cases involve 80% of the health care costs. Although physiotherapy and occupational therapy consist of only a small proportion of these costs, it is nevertheless important to evaluate the factors that predict its use in order to improve services (i.e. allocation of resources to those who need them and benefit most).Patients and methods.- In this longitudinal prospective study, the cohort consisted of 2156 consecutively included patients with orthopaedic problems attending the clinique Romande de réadaptation (CRR) at Sion for inpatient rehabilitation after a work, traffic or leisure related injury. Two years after discharge, a questionnaire regarding the use of different health cares was send to the patients (1502 patients returned their questionnaires). The aim of this study was to calculate, with a logistic multivariate model, in-patient hospitalized for orthopaedic problems, the variables that mostly predict physiotherapy use 2 years after discharge.Results.- The full multivariate model contains 46 predictors. The use of physiotherapy and occupational therapy was significantly predicted in this multivariate model by the following predictors: Patients with a spinal problem (OR 1.51 versus lower-extremity problem, 95% CI 1.01 to 2.27), a disability pension (OR 1.69, 95% CI 1.09 to 2.60), patients with sports activities (OR 1.56, 95% CI 1.26 to 1.94), patients with longer stay at the rehabilitation clinic (OR 1.22 per week, 95% CI 1.05 to 1.41), women (OR 1.64, 95% CI 1.09 to 2.48) and those consulting a psychiatrist (OR 1.66, 95% CI 1.06 to 2.60).Discussion.- In this prospective study with a 2-year follow-up, different factors predicted the use of physiotherapy and occupational therapy after an injury. Further studies are needed to clarify the impact of these factors for the health care utilization and the strategies, which would allow to improve allocation of available resources.

Measuring potentially avoidable hospital readmissions.

The objectives of this study were to develop a computerized method to screen for potentially avoidable hospital readmissions using routinely collected data and a prediction model to adjust rates for case mix. We studied hospital information system data of a random sample of 3,474 inpatients discharged alive in 1997 from a university hospital and medical records of those (1,115) readmitted within 1 year. The gold standard was set on the basis of the hospital data and medical records: all readmissions were classified as foreseen readmissions, unforeseen readmissions for a new affection, or unforeseen readmissions for a previously known affection. The latter category was submitted to a systematic medical record review to identify the main cause of readmission. Potentially avoidable readmissions were defined as a subgroup of unforeseen readmissions for a previously known affection occurring within an appropriate interval, set to maximize the chance of detecting avoidable readmissions. The computerized screening algorithm was strictly based on routine statistics: diagnosis and procedures coding and admission mode. The prediction was based on a Poisson regression model. There were 454 (13.1%) unforeseen readmissions for a previously known affection within 1 year. Fifty-nine readmissions (1.7%) were judged avoidable, most of them occurring within 1 month, which was the interval used to define potentially avoidable readmissions (n = 174, 5.0%). The intra-sample sensitivity and specificity of the screening algorithm both reached approximately 96%. Higher risk for potentially avoidable readmission was associated with previous hospitalizations, high comorbidity index, and long length of stay; lower risk was associated with surgery and delivery. The model offers satisfactory predictive performance and a good medical plausibility. The proposed measure could be used as an indicator of inpatient care outcome. However, the instrument should be validated using other sets of data from various hospitals.

The Mixed Management of Patients' Medical Records: Responsibility Sharing Between the Patient and the Physician

Through this article, we propose a mixed management of patients' medical records, so as to share responsibilities between the patient and the Medical Practitioner by making Patients responsible for the validation of their administrative information, and MPs responsible for the validation of their Patients' medical information. Our proposal can be considered a solution to the main problem faced by patients, health practitioners and the authorities, namely the gathering and updating of administrative and medical data belonging to the patient in order to accurately reconstitute a patient's medical history. This method is based on two processes. The aim of the first process is to provide a patient's administrative data, in order to know where and when the patient received care (name of the health structure or health practitioner, type of care: out patient or inpatient). The aim of the second process is to provide a patient's medical information and to validate it under the accountability of the Medical Practitioner with the help of the patient if needed. During these two processes, the patient's privacy will be ensured through cryptographic hash functions like the Secure Hash Algorithm, which allows pseudonymisation of a patient's identity. The proposed Medical Record Search Engines will be able to retrieve and to provide upon a request formulated by the Medical ractitioner all the available information concerning a patient who has received care in different health structures without divulging the patient's identity. Our method can lead to improved efficiency of personal medical record management under the mixed responsibilities of the patient and the MP.

Derivation and validation of a prognostic model for pulmonary embolism.

RATIONALE: An objective and simple prognostic model for patients with pulmonary embolism could be helpful in guiding initial intensity of treatment. OBJECTIVES: To develop a clinical prediction rule that accurately classifies patients with pulmonary embolism into categories of increasing risk of mortality and other adverse medical outcomes. METHODS: We randomly allocated 15,531 inpatient discharges with pulmonary embolism from 186 Pennsylvania hospitals to derivation (67%) and internal validation (33%) samples. We derived our prediction rule using logistic regression with 30-day mortality as the primary outcome, and patient demographic and clinical data routinely available at presentation as potential predictor variables. We externally validated the rule in 221 inpatients with pulmonary embolism from Switzerland and France. MEASUREMENTS: We compared mortality and nonfatal adverse medical outcomes across the derivation and two validation samples. MAIN RESULTS: The prediction rule is based on 11 simple patient characteristics that were independently associated with mortality and stratifies patients with pulmonary embolism into five severity classes, with 30-day mortality rates of 0-1.6% in class I, 1.7-3.5% in class II, 3.2-7.1% in class III, 4.0-11.4% in class IV, and 10.0-24.5% in class V across the derivation and validation samples. Inpatient death and nonfatal complications were <or= 1.1% among patients in class I and <or= 1.9% among patients in class II. CONCLUSIONS: Our rule accurately classifies patients with pulmonary embolism into classes of increasing risk of mortality and other adverse medical outcomes. Further validation of the rule is important before its implementation as a decision aid to guide the initial management of patients with pulmonary embolism.

Hospital antibiotic consumption in Switzerland: comparison of a multicultural country with Europe.

The consumption of antibiotics in the inpatient setting of Switzerland was assessed to determine possible differences between linguistic regions, and to compare these results with European results. Data on antibiotic consumption were obtained from a sentinel network representing 54% of the national acute care hospitals, and from a private drug market monitoring company. Aggregated data were converted into defined daily doses (DDD). The total consumption density in Switzerland was close to the median consumption reported in European surveys. Between 2004 and 2008, the total consumption of systemic antibiotics rose from 46.1 to 54.0 DDD per 100 occupied bed-days in the entire hospitals, and from 101.6 to 114.3 DDD per 100 occupied bed-days in the intensive care units. Regional differences were observed for total consumption and among antibiotic classes. Hospitals in the Italian-speaking region showed a significantly higher consumption density, followed by the French- and German-speaking regions. Hospitals in the Italian-speaking region also had a higher consumption of fluoroquinolones, in line with the reported differences between Italy, Germany and France. Antibiotic consumption in acute care hospitals in Switzerland is close to the European median with a relatively low consumption in intensive care units. Some of the patterns of variation in consumption levels noticed among European countries are also observed among the cultural regions of Switzerland.

HIV Testing Practices by Clinical Service before and after Revised Testing Guidelines in a Swiss University Hospital.

OBJECTIVES: To determine 1) HIV testing practices in a 1400-bed university hospital where local HIV prevalence is 0.4% and 2) the effect on testing practices of national HIV testing guidelines, revised in March 2010, recommending Physician-Initiated Counselling and Testing (PICT). METHODS: Using 2 hospital databases, we determined the number of HIV tests performed by selected clinical services, and the number of patients tested as a percentage of the number seen per service ('testing rate'). To explore the effect of the revised national guidelines, we examined testing rates for two years pre- and two years post-PICT guideline publication. RESULTS: Combining the clinical services, 253,178 patients were seen and 9,183 tests were performed (of which 80 tested positive, 0.9%) in the four-year study period. The emergency department (ED) performed the second highest number of tests, but had the lowest testing rates (0.9-1.1%). Of inpatient services, neurology and psychiatry had higher testing rates than internal medicine (19.7% and 9.6% versus 8%, respectively). There was no significant increase in testing rates, either globally or in the majority of the clinical services examined, and no increase in new HIV diagnoses post-PICT recommendations. CONCLUSIONS: Using a simple two-database tool, we observe no global improvement in HIV testing rates in our hospital following new national guidelines but do identify services where testing practices merit improvement. This study may show the limit of PICT strategies based on physician risk assessment, compared to the opt-out approach.

Pediatric drug-related problems: a multicenter study in four French-speaking countries.

BACKGROUND: Pediatric intensive care patients represent a population at high risk for drug-related problems. There are few studies that compare the activity of clinical pharmacists between countries. OBJECTIVE: To describe the drug-related problems identified and interventions by four pharmacists in a pediatric cardiac and intensive care unit. SETTING: Four pediatric centers in France, Quebec, Switzerland and Belgium. METHOD: This was a six-month multicenter, descriptive and prospective study conducted from August 1, 2009 to January 31, 2010. Drug-related problems and clinical interventions were compiled from four pediatric centers in France, Quebec, Switzerland and Belgium. Data on patients, drugs, intervention, documentation, approval and estimated impact were compiled. MAIN OUTCOME MEASURE: Number and type of drug-related problems encountered in a large pediatric inpatient population. RESULTS: A total of 996 interventions were recorded: 238 (24 %) in France, 278 (28 %) in Quebec, 351 (35 %) in Switzerland and 129 (13 %) in Belgium. These interventions targeted 270 patients (median 21 months old, 53 % male): 88 (33 %) in France, 56 (21 %) in Quebec, 57 (21 %) in Switzerland and 69 (26 %) in Belgium. The main drug-related problems were inappropriate administration technique (29 %), untreated indication (25 %) and supra-therapeutic dose (11 %). The pharmacists' interventions were mostly optimizing the mode of administration (22 %), dose adjustment (20 %) and therapeutic monitoring (16 %). The two major drug classes that led to interventions were anti-infectives for systemic use (23 %) and digestive system and metabolism drugs (22 %). Interventions mainly involved residents and all clinical staff (21 %). Among the 878 (88 %) proposed interventions requiring physician approval, 860 (98 %) were accepted. CONCLUSION: This descriptive study illustrates drug-related problems and the ability of clinical pharmacists to identify and resolve them in pediatric intensive care units in four French-speaking countries.

Heart failure and community-acquired pneumonia: cases for home hospital?

BACKGROUND: Home hospital is advocated in many western countries in spite of limited evidence of its economic advantage over usual hospital care. Heart failure and community-acquired pneumonia are two medical conditions which are frequently targeted by home hospital programs. While recent trials were devoted to comparisons of safety and costs, the acceptance of home hospital for patients with these conditions remains poorly described. OBJECTIVE: To document the medical eligibility and final transfer decision to home hospital for patients hospitalized with a primary diagnosis of heart failure or community-acquired pneumonia. DESIGN: Longitudinal study of patients admitted to the medical ward of acute care hospitals, up to the final decision concerning their transfer. SETTING: Medical departments of one university hospital and two regional teaching Swiss hospitals. PATIENTS: All patients admitted over a 9 month period to the three settings with a primary diagnosis of heart failure (n= 301) or pneumonia (n=441). MEASUREMENTS: Presence of permanent exclusion criteria on admission; final decision of (in)eligibility based on medical criteria; final decision regarding the transfer, taking into account the opinions of the family physician, the patient and informal caregivers. RESULTS: While 27.9% of heart failure and 37.6% of pneumonia patients were considered to be eligible from a medical point of view, the program acceptance by family physicians, patients and informal caregivers was low and a transfer to home hospital was ultimately chosen for just 3.8% of heart failure and 9.6% of pneumonia patients. There were no major differences between the three settings. CONCLUSIONS: In the case of these two conditions, the potential economic advantage of home hospital over usual inpatient care is compromised by the low proportion of patients ultimately transferred.

Surgical safety and hospital volume across a wide range of interventions

OBJECTIVES:: For certain major operations, inpatient mortality risk is lower in high-volume hospitals than those in low-volume hospitals. Extending the analysis to a broader range of interventions and outcomes is necessary before adopting policies based on minimum volume thresholds. METHODS:: Using the United States 2004 Nationwide Inpatient Sample, we assessed the effect of intervention-specific and overall hospital volume on surgical complications, potentially avoidable reoperations, and deaths across 1.4 million interventions in 353 hospitals. Outcome variations across hospitals were analyzed through a 3-level hierarchical logistic regression model (patients, surgical interventions, and hospitals), which took into account interventions on multiple organs, 144 intervention categories, and structural hospital characteristics. Discriminative performance and calibration were good. RESULTS:: Hospitals with more experience in a given intervention had similar reoperation rates but lower mortality and complication rates: odds ratio per volume deciles 0.93 and 0.97. However, the benefit was limited to heart surgery and a small number of other operations. Risks were higher for hospitals that performed more interventions overall: odds ratio per 1000 for each event was approximately 1.02. Even after adjustment for specific volume, mortality varied substantially across both high- and low-volume hospitals. CONCLUSION:: Although the link between specific volume and certain inpatient outcomes suggests that specialization might help improve surgical safety, the variable magnitude of this link and the heterogeneity of hospital effect do not support the systematic use of volume-based referrals. It may be more efficient to monitor risk-adjusted postoperative outcomes and to investigate facilities with worse than expected outcomes.

Differences between first episode schizophrenia and schizoaffective disorder.

BACKGROUND: The diagnostic and clinical overlap between schizophrenia and schizoaffective disorder is an important nosological issue in psychiatry that is yet to be resolved. The aim of this study was to compare the clinical and functional characteristics of an epidemiological treated cohort of first episode patients with an 18-month discharge diagnosis of schizophrenia (FES) or schizoaffective disorder (FESA). METHODS: This study was part of the larger First Episode Psychosis Outcome Study (FEPOS) which involved a medical file audit study of all 786 patients treated at the Early Psychosis Prevention and Intervention Centre between 1998 and 2000. Of this cohort, 283 patients had an 18-month discharge diagnosis of FES and 64 had a diagnosis of FESA. DSM-IV diagnoses and clinical and functional ratings were derived and validated by two consultant psychiatrists. RESULTS: Compared to FES patients, those with FESA were significantly more likely to have a later age of onset (p=.004), longer prodrome (p=.020), and a longer duration of untreated psychosis (p<.001). At service entry, FESA patients presented with a higher illness severity (p=.020), largely due to the presence of more severe manic symptoms (p<.001). FESA patients also had a greater number of subsequent inpatient admissions (p=.017), had more severe depressive symptoms (p=.011), and higher levels of functioning at discharge. DISCUSSION: The findings support the notion that these might be considered two discernable disorders; however, further research is required to ascertain the ways and extent to which these disorders are discriminable at presentation and over time.
