Engorgement des centres d'urgences: une raison légitime de refuser l'accès aux patients non urgents [Emergency department overcrowding: a legitimate reason to refuse access to urgent care for non-urgent patients?].

Non-urgent cases represent 30-40% of all ED consults; they contribute to overcrowding of emergency departments (ED), which could be reduced if they were denied emergency care. However, no triage instrument has demonstrated a high enough degree of accuracy to safely rule out serious medical conditions: patients suffering from life-threatening emergencies have been inappropriately denied care. Insurance companies have instituted financial penalties to discourage the use of ED as a source of non-urgent care, but this practice mainly restricts access for the underprivileged. More recent data suggest that in fact most patients consult for appropriate urgent reasons, or have no alternate access to urgent care. The safe reduction of overcrowding requires a reform of the healthcare system based on patients' needs rather than access barriers.

Referrals of cancer versus non-cancer patients to palliative care consult team : do they differ ?

Depuis la fin du XXème siècle, les soins palliatifs se sont développés essentiellement autour de patients souffrant de cancer en phase terminale. Or depuis une dizaine d'années, un nombre croissant d'études rapporte que les patients souffrant de maladies non cancéreuses avancées expérimentent également une variété de problèmes, de dimension physique, psychosociale ou spirituelle. Ces problèmes peuvent avoir un fort impact sur leur qualité de vie. Malheureusement, seule une minorité de patients non cancéreux en phase terminale a accès à des soins palliatifs. Le but de cette étude est de mieux comprendre les similitudes et les différences entre les patients cancéreux et non cancéreux lorsqu'ils sont encore hospitalisés dans un hôpital universitaire de soins aigus et réferrés à une équipe mobile de soins palliatifs intrahospitalière. Méthodologie : Dans cette étude rétrospective, les dossiers des 100 premiers patients non cancéreux adressés à l'équipe mobile de soins palliatifs (EMSP) ont été comparés avec ceux de 506 patients cancéreux, durant la même période (2000-2001). Nous avons répertorié leurs profils démographiques, les types de demandes des professionnels de 1ère ligne s'adressant à l'EMSP, les symptômes ainsi que la médication des patients. Conclusions : Dans les deux groupes de patients, nous avons retrouvé de manière égale un haut taux de symptômes : 79% de patients non cancéreux et 71% de patients cancéreux expérimentent au moins 3 symptômes ou plus. Cependant, malgré cette similitude en termes d'inconfort, l'équipe de soins palliatifs est appelée plus tardivement pour les patients non cancéreux. Au vu des problèmes de communication verbale chez les patients non cancéreux, les demandes d'évaluation formulées auprès de l'EMSP sont plus orientées vers « une évaluation globale » au lieu d'une aide sur un problème spécifique. Nous retrouvons également une différence en termes d'analgésie entre les deux populations de patients, les patients non cancéreux sont plus fréquemment en surdosage. Selon nos données, un plus grand taux de décès survient à l'hôpital auprès des patients non cancéreux. Dans les limites de cette étude, les résultats permettent de confirmer que les patients non cancéreux hospitalisés dans un hôpital de soins aigus sont encore peu référés à une EMSP et très tardivement. Pour y rémédier, il serait nécessaire de contourner ces obstacles au vu des problèmes d'évaluation et d'identification exposés dans cette étude, d'améliorer la collaboration avec les professionnels de 1ère ligne et peut-être de mettre en place des guidelines institutionnels afin que tous les patients palliatifs puissent avoir la meilleure qualité de vie possible, et ce, jusqu'au bout de leur trajectoire hospitalière.

Referrals of cancer versus non-cancer patients to a palliative care consult team: do they differ?

This retrospective study compared 100 consecutive non-cancer (NC) patients referred to a palliative care consult team (PCT) in a Swiss university hospital to 506 cancer (C) patients referred during the same period. The frequencies of reported symptoms were similar in both groups. The main reasons for referral in the NC group were symptom control, global evaluation, and assistance with discharge. Requests for symptom control predominated in the C group. Prior to the first visit, 50% of NC patients were on opioids, compared to 58% of C patients. After the first visit, the proportion of NC patients on opioids increased to 64% and the proportion of C patients to 73%. The median daily oral morphine equivalent dose for NC patients taking opioids prior to the first PCT visit was higher than that for C patients (60 mg versus 45 mg). At the time of death or discharge, the percentage of NC patients on opioids was 64%, while that of C patients was 76%. Moreover, NC patients were on significantly lower median doses of opioids than C patients (31 mg versus 60 mg). Over half the NC patients died during hospitalization, as compared to 33% of C patients. Only 6% of NC patients were discharged to palliative care units, as compared to 22% of C patients.

Survey of aspergillosis in non-neutropenic patients in Swiss teaching hospitals.

Clin Microbiol Infect 2011; 17: 1366-1371 ABSTRACT: Invasive aspergillosis (IA) is a live-threatening opportunistic infection that is best described in haematological patients with prolonged neutropenia or graft-versus-host disease. Data on IA in non-neutropenic patients are limited. The aim of this study was to establish the incidence, disease manifestations and outcome of IA in non-neutropenic patients diagnosed in five Swiss university hospitals during a 2-year period. Case identification was based on a comprehensive screening of hospital records. All cases of proven and probable IA were retrospectively analysed. Sixty-seven patients were analysed (median age 60 years; 76% male). Sixty-three per cent of cases were invasive pulmonary aspergillosis (IPA), and 17% of these were disseminated aspergillosis. The incidence of IPA was 1.2/10 000 admissions. Six of ten cases of extrapulmonary IA affected the brain. There were six cases of invasive rhinosinusitis, six cases of chronic pulmonary aspergillosis, and cases three of subacute pulmonary aspergillosis. The most frequent underlying condition of IA was corticosteroid treatment (57%), followed by chronic lung disease (48%), and intensive-care unit stays (43%). In 38% of patients with IPA, the diagnosis was established at autopsy. Old age was the only risk factor for post-mortem diagnosis, whereas previous solid organ transplantation and chronic lung disease were associated with lower odds of post-mortem diagnosis. The mortality rate was 57%.

Roux-en-y Gastric Bypass is Superior to Gastric Banding in Non-superobese Patients. a Matched-case Study with Five-year Follow-up

Background: Roux-en-Y gastric bypass (RYGBP) and gastric banding (GB) are the two most popular bariatric procedures. Only few studies have compared their results and follow-up duration is usually limited to <3 years. Patients and Methods: Using our prospective bariatric database, we matched non-superobese GB to RYGBP patients for sex, age and BMI to RYGBP. Follow-up considered up to five years. Results: 442 patients were matched in 221 pairs. Mean age (38,6) and mean BMI (43) were identical. Overall operative morbidity was higher after RYGBP (17,2 versus 5,4 %, p<0,001), but major morbidity was similar (3,6 versus 2,2 %, p=0,57). More patients developed long-term complications after GB (43,9 % versus 19 %, p<0,001), and more required reoperations (24,4 % versus 12 %, p=0,001). After RYGBP, reoperations were mainly due to internal hernias (87 %), with no reversal, whereas 18,5 % of the GB patients required band removal. Even including only patients who retained their band, weight loss after RYGBP was better throughout the study period, with 5-year EBMIL of 77,6 % and 61,7 % (p<0,001) after RYGBP and GB respectively. RYGBP was associated with better food tolerance and greater improvement of the lipid profile. Conclusions: GB is associated with a smaller overall operative morbidity and similar major morbidity, but with more long-term complications, more reoperations, a significant number of reversal or conversion procedures, and reduced weight loss when compared with RYGBP. Five-year results of RYGBP are superior to GB and patients should be informed accordingly.

Hyperhomocysteinaemia in young patients with non-arteritic anterior ischaemic optic neuropathy.

BACKGROUND/AIM: Elevated plasma homocysteine is a newly identified vascular risk factor among patients under age 55 years with cerebrovascular, cardiovascular, or peripheral vascular disease. This study sought to evaluate retrospectively the plasma homocysteine status among healthy younger patients with ischaemic optic disc disease. METHODS: 12 non-diabetic patients who had been diagnosed with non-arteritic anterior ischaemic optic neuropathy (NAION) before the age of 50 years were identified from chart review. None had experienced previous ischaemic cerebrovascular, cardiovascular, or peripheral vascular events. Plasma homocysteine, CBC, renal function, vitamin B6, vitamin B12, and folate levels were sampled in the fasting state. RESULTS: Two of 12 patients (17%) had hyperhomocysteinaemia. Both had experienced NAION in both eyes with recurrent episodes. Neither patient was hypertensive nor had a smoking history. One of these two patients had mild hypercholesterolaemia which did not warrant medication. CONCLUSIONS: Elevated plasma homocysteine may be associated with NAION. An evaluation for hyperhomocysteinaemia should be considered in patients with NAION who do not have the typical risk factor such as older age, diabetes, hypertension, or tobacco use. It should also be considered in young patients with bilateral or recurrent attacks of NAION.

Stress ulcer prophylaxis in non-critically ill patients: a prospective evaluation of current practice in a general surgery department

Objective: There is little evidence regarding the benefit of stress ulcer prophylaxis (SUP) outside critical care setting. Over-prescription of SUP is not devoid of risks. This prospective study aimed to evaluate the use of proton pump inhibitors (PPIs) for SUP in a general surgery department.Methods: Data collection was performed prospectively during an 8-week period on patients hospitalized in a general surgery department (58 beds) by pharmacists. Patients with a PPI prescription for the treatment of ulcers, gastro-oesophageal reflux disease, oesophagitis or epigastric pain were excluded. Patients admitted twice during the study period were not re-included. The American Society of Health-System Pharmacists guidelines on SUP were used to assess the appropriateness of de novo PPI prescriptions.Results: Among 255 consecutive patients in the study, 138 (54%) received a prophylaxis with PPI, of which 86 (62%) were de novo PPI prescriptions. One-hundred twenty-nine patients (94%) received esomeprazole (according to the hospital drug policy). The most frequent dosage was 40 mg/day. Use of PPI for SUP was evaluated in 67 patients. Fifty-three patients (79%) had no risk factors for SUP. Twelve and 2 patients had one or two risk factors, respectively. At discharge, PPI prophylaxis was continued in 34% of patients with a de novo PPI prescription.Conclusion: This study highlights the overuse of PPIs in non-ICU patients and the inappropriate continuation of PPI prescriptions at discharge.Treatment

Stress ulcer prophylaxis in non-critically ill patients: a prospective evaluation of the practice in a surgical ward

Introduction The benefit of stress ulcer prophylaxis (SUP) in noncriticallyill patients has not been proved. Over-prescription of SUP isnot devoided of risks (i.e. drug-drug interactions, adverse events).This prospective study aimed to evaluate the use of proton pumpinhibitors (PPIs) for SUP in a visceral surgery ward.Materials & Methods Data collection was performed prospectivelyduring a 8-week period on patients hospitalized in a visceral surgeryward (58 beds). Patients with a PPI prescription for the treatment ofulcers, gastroesophageal reflux disease, esophagitis or epigastralgiawere excluded as well as patients hospitalized twice during the studyperiod. The American Society of Health-System Pharmacists guidelineson SUP were used to assess the appropriateness of de novo PPIprescriptions.Results Among 255 patients in the study, 138 (54.1%) received aprophylaxis with PPI, of which 86 (62.3%) were de novo PPI prescriptions.93.5% of patients received esomeprazole (according to thehospital drug formulary) mainly orally at 40 mg qd. 79.1% of patientshad no risk factors for SUP. 17.9% and 3.0% had one and two riskfactors, respectively. 95% of the patients with PPI were not hospitalizedin the intensive care unit (ICU) before their stay in the visceralsurgery ward. At discharge, PPI therapy was continued in 34.2% ofpatients with a de novo PPI prescription.Discussion & Conclusion This study highlights the over-utilizationof PPIs in non-ICU patients and the inappropriate continuation of PPIprescriptions at discharge. The PPI dosage prescribed for prophylaxiswas probably too high compared with the data of the literature.Treatment recommendations for SUP are needed to restrict PPIuse for justified indications.

Radiologists' vs. surgeons' reading performance in non traumatic acute abdomen CTs : P32

Purpose: Emergency room reading performances have been a point of interest in recent studies comparing radiologists to other physician groups. Our objective was to evaluate and compare the reading performances of radiologists and surgeons in an emergency room setting of non-traumatic abdominal CTs. Methods and materials: A total of ten readers representing four groups participated in this study: three senior radiologists and visceral surgeons, respectively, and two junior radiologists and surgeons, respectively. Each observer blindedly evaluated a total of 150 multi-slice acute abdominal CTs. CTs were chosen representing established proportions of acute abdomen pathologies in a Level I trauma centre from 2003 to 2005. Each answer was interpretated as right or wrong regarding pathology location, diagnosis and need for operation. Gold standard was the intraoperative result, and the clinical patient follow-up for non-operated patients. Significance was assumed at a p <.05 level. Results: Senior radiologists had a mean score of 2.38 ± 1.14, junior radiologists a score of 2.34 ± 1.14, whereas senior surgeons scored 2.07 ± 1.30 and junior surgeons 1.62 ± 1.42. No significant difference was found between the two radiologist groups, but results were significantly better for senior surgeons as compared to junior surgeons and better for the two radiologist groups as compared to each of the surgeon groups (all p <.05). Conclusion: Abdominal CT reading in an acute abdomen setting should continue to rely on an evaluation by a radiologist, whether senior or junior. Satisfying reading results can be achieved by senior visceral surgeons, but junior surgeons need more experience for a good reading performance.

Influence of socioeconomic factors on delays, management and boutcome amongst patients with acute myocardial infarction undergoing primary percutaneous coronary intervention

Background¦The outcome after primary percutaneous coronary intervention (pPCI) for STElevation¦Myocardial Infarction (STEMI) is strongly affected by time delays. In thepresent study, we sought to identify the impact of specific socioeconomic factors on time delays, subsequent STEMI management and outcomes in STEMI patients from a well-defined region of the French part of Switzerland.¦Method¦A total of 402 consecutive patients undergoing pPCI for STEMI in a large tertiary hospital were retrospectively studied. Symptom-to-first-medical-contact time was analyzed for the following socioeconomic factors: level of education, gender, origin and marital status. Main exclusion criteria were: time delay beyond 12 hours, previous treatment by fibrinolysis or patients immediately referred for CABG.¦Therefore, 352 patients were finally included.¦Results¦At one year, there was no difference in mortality amongst the different socioeconomic groups. Furthermore, there was no difference in management characteristics between them. Symptom-to-first-medical-contact time was significantly higher for patients with a low level of education, Swiss citizens and non-married patients with median differences of 40 minutes, 48 minutes, and 60 minutes, respectively (p<0.05).¦Nevertheless, no difference was found regarding in-hospital management and clinical outcome.¦Conclusion¦This study demonstrates that symptom-to-first-medical-contact time is higher amongst people with a lower educational level, Swiss-citizens, and non-married people. Because of the low mortality rate in general, these differences in time delays did not affect clinical outcomes. Still, primary prevention measures should particularly focus on these vulnerable populations.

Proportion of out of hospital adult non traumatic cardiac arrest presenting as a convulsion

Introduction: The majority of convulsions are due to an epilepticseizure or a convulsive syncope. In some cases, this is the firstsymptom of an out of hospital cardiac arrest (OH-CA).Objective: This study was aimed to measure the proportion of adultnon traumatic OH-CA presenting as a convulsion.Methodology: We prospectively collected all incoming calls with anout-of-hospital non traumatic seizure as the chief complaint in patients>18 years during a 24-months period. Among these calls, we collectedcases identified as OH-CA by paramedics.Results: During the 24-months period, the EMS dispatch centerreceived 561 calls for an out-of-hospital non traumatic convulsion in anadult. Twelve cases were ultimately classified as CA. In this group, onebystander spontaneously reported that the patient was known forepilepsy. The incidence of OH-CA presenting as convulsions wastherefore 2.1% of all calls for convulsion. Over the same period, theEMS dispatch center received 1035 calls related to an adult nontraumatic OH-CA. Therefore the rate of OH-CA presenting as aconvulsion represented 1.2% of all adult non traumatic OH-CA.Conclusion: Only 12 cases out of the 531 calls for non traumatic adultconvulsions were confirmed OH-CA (2.1%). Nevertheless, this unusualpresentation of OH-CA must be recognized by dispatchers, even whena patient is reported by bystander as a known epileptic. Dispatchersshould keep bystanders on line or call them back before paramedics'arrival, and have them confirm the progressive return of a normalpattern of breathing and state of consciousness; if not, they shouldencourage when necessary bystander to initiate CPR. For dispatchers,a past medical history of epilepsy should not be regarded as sufficientinformation to rule-out OH-CA. It is mandatory that known epilepticpatients should be monitored in the same way as non-epileptic patients.

Physicians' estimates of the 10 year cardiovascular risk in hypertensive patients: an evaluation in primary care physicians in training.

To evaluate how young physicians in training perceive their patients' cardiovascular risk based on the medical charts and their clinical judgment. Cross sectional observational study. University outpatient clinic, Lausanne, Switzerland. Two hundred hypertensive patients and 50 non-hypertensive patients with at least one cardiovascular risk factor. Comparison of the absolute 10-year cardiovascular risk calculated by a computer program based on the Framingham score and adapted for physicians by the WHO/ISH with the perceived risk as assessed clinically by the physicians. Physicians underestimated the 10-year cardiovascular risk of their patients compared to that calculated with the Framingham score. Concordance between methods was 39% for hypertensive patients and 30% for non-hypertensive patients. Underestimation of cardiovascular risks for hypertensive patients was related to the fact they had a stabilized systolic blood pressure under 140 mm Hg (OR = 2.1 [1.1; 4.1]). These data show that young physicians in training often have an incorrect perception of the cardiovascular risk of their patients with a tendency to underestimate the risk. However, the calculated risk could also be slightly overestimated when applying the Framingham Heart Study model to a Swiss population. To implement a systematic evaluation of risk factors in primary care a greater emphasis should be placed on the teaching of cardiovascular risk evaluation and on the implementation of quality improvement programs.

Effects of a whey protein supplementation on intrahepatocellular lipids in obese female patients.

Background & aims: High protein diets have been shown to improve hepatic steatosis in rodent models and in high-fat fed humans. We therefore evaluated the effects of a protein supplementation on intrahepatocellular lipids (IHCL), and fasting plasma triglycerides in obese non diabetic women.Methods: Eleven obese women received a 60 g/day whey protein supplement (WPS) for 4-weeks, while otherwise nourished on a spontaneous diet, IHCL concentrations, visceral body fat, total liver volume (MR), fasting total-triglyceride and cholesterol concentrations, glucose tolerance (standard 75 g OGTT), insulin sensitivity (HOMA IS index), creatinine clearance, blood pressure and body composition (bio-impedance analysis) were assessed before and after 4-week WPS.Results: IHCL were positively correlated with visceral fat and total liver volume at inclusion. WPS decreased significantly IHCL by 20.8 +/- 7.7%, fasting total TG by 15 +/- 6.9%, and total cholesterol by 7.3 +/- 2.7%. WPS slightly increased fat free mass from 54.8 +/- 2.2 kg to 56.7 +/- 2.5 kg, p = 0.005). Visceral fat, total liver volume, glucose tolerance, creatinine clearance and insulin sensitivity were not changed.Conclusions: WPS improves hepatic steatosis and plasma lipid profiles in obese non diabetic patients, without adverse effects on glucose tolerance or creatinine clearance.

D-dimer levels and 90-day outcome in patients with acute pulmonary embolism with or without cancer.

BACKGROUND: The prognostic value of D-dimer testing in patients with acute pulmonary embolism (PE) has not been thoroughly studied. METHODS: We used the RIETE Registry data to assess the 90-day prognostic value of increased IL Test D-dimer levels at baseline in patients with PE, according to the presence or absence of cancer. RESULTS: As of May 2013, 3,283 patients with acute PE underwent D-dimer testing using IL Test D-dimer. Among 2,588 patients without cancer, those with D-dimer levels in the highest quartile had a higher rate of fatal PE (2.6% vs. 0.9%; p=0.002), fatal bleeding (1.1% vs. 0.3%; p=0.017) and all-cause death (9.1% vs. 4.4%; p<0.001) at 90 days compared with those with levels in the lowest quartiles. Among 695 patients with cancer, those with levels in the highest quartile had a similar rate of fatal PE or fatal bleeding but higher mortality (35% vs. 24%; p<0.01). On multivariate analysis, non-cancer patients with D-dimer levels in the highest quartile had an increased risk for fatal PE (odds ratio [OR]: 3.3; 95% CI: 1.6-6.6), fatal bleeding (OR: 4.3; 95% CI: 1.4-13.7) and all-cause death (OR: 2.1; 95% CI: 1.4-3.1) compared with patients with levels in the lowest quartiles. CONCLUSIONS: Non-cancer patients with acute PE and IL Test D-dimer levels in the highest quartile had an independently higher risk for fatal PE, fatal bleeding and all-cause death at 90 days than those with levels in the lowest quartiles. In patients with cancer, D-dimer levels failed to predict fatal PE or fatal bleeding.

AIDS defining opportunistic infections in patients with high CD4 counts in the combination antiretroviral therapy (cART) era: things ain't what they used to be.

INTRODUCTION: According to reports from observational databases, classic AIDS-defining opportunistic infections (ADOIs) occur in patients with CD4 counts above 500/µL on and off cART. Adjudication of these events is usually not performed. However, ADOIs are often used as endpoints, for example, in analyses on when to start cART. MATERIALS AND METHODS: In the database, Swiss HIV Cohort Study (SHCS) database, we identified 91 cases of ADOIs that occurred from 1996 onwards in patients with the nearest CD4 count >500/µL. Cases of tuberculosis and recurrent bacterial pneumonia were excluded as they also occur in non-immunocompromised patients. Chart review was performed in 82 cases, and in 50 cases we identified CD4 counts within six months before until one month after ADOI and had chart review material to allow an in-depth review. In these 50 cases, we assessed whether (1) the ADOI fulfilled the SHCS diagnostic criteria (www.shcs.ch), and (2) HIV infection with CD4 >500/µL was the main immune-compromising condition to cause the ADOI. Adjudication of cases was done by two experienced clinicians who had to agree on the interpretation. RESULTS: More than 13,000 participants were followed in SHCS in the period of interest. Twenty-four (48%) of the chart-reviewed 50 patients with ADOI and CD4 >500/µL had an HIV RNA <400 copies/mL at the time of ADOI. In the 50 cases, candida oesophagitis was the most frequent ADOI in 30 patients (60%) followed by pneumocystis pneumonia and chronic ulcerative HSV disease (Table 1). Overall chronic HIV infection with a CD4 count >500/µL was the likely explanation for the ADOI in only seven cases (14%). Other reasons (Table 1) were ADOIs occurring during primary HIV infection in 5 (10%) cases, unmasking IRIS in 1 (2%) case, chronic HIV infection with CD4 counts <500/µL near the ADOI in 13 (26%) cases, diagnosis not according to SHCS diagnostic criteria in 7 (14%) cases and most importantly other additional immune-compromising conditions such as immunosuppressive drugs in 14 (34%). CONCLUSIONS: In patients with CD4 counts >500/ µL, chronic HIV infection is the cause of ADOIs in only a minority of cases. Other immuno-compromising conditions are more likely explanations in one-third of the patients, especially in cases of candida oesophagitis. ADOIs in HIV patients with high CD4 counts should be used as endpoints only with much caution in studies based on observational databases.
