RESUMO

OBJECTIVE: To develop an automatic gout register from electronic health records (EHRs) data. METHODS: We analysed the EHR of all patients >18 years old from a tertiary academic hospital (2013-2022) based on six criteria: International Classification of Diseases 10 gout diagnosis, urate-lowering therapy prescription, monosodium urate crystals in joint aspiration and gout-related terms in problem lists, clinical or imaging reports. We assessed the positive and negative predictive value (PPV and NPV) of the query by chart reviews. RESULTS: Of 2 110 902 outpatients and inpatients, 10 289 had at least one criterion for gout. The combination of joint aspiration OR diagnostic in the problem list OR≥2 other criteria created a register of 5138 patients, with a PPV of 92.4% (95% CI 88.5% to 95.0%) and an NPV of 94.3% (95% CI 91.9% to 96.0%). PPV and NPV were similar among outpatients and inpatients. Incidence was 2.9 per 1000 person-year and dropped by 30% from the COVID-19 pandemic onward. Patients with gout were on average 71.2 years old (SD 14.9), mainly male (76.5%), overweight (69.5%) and polymorbid (mean number of comorbidities of 3, IQR 1-5). More than half (57.4%) had received a urate-lowering treatment, 6.7% had a gout that led to a hospitalisation or ≥2 flares within a year and 32.9% received a rheumatology consultation. CONCLUSION: An automatic EHR-based gout register is feasible, valid and could be used to evaluate and improve gout management. Interestingly, the register uncovered a marked underdiagnosis or under-reporting of gout since the COVID-19 pandemic.

RESUMO

Pleural space infections occur in approximately 10% of patients hospitalized for pneumonia and their incidence is increasing with an aging population. Pulmonary ultrasound is a good bedside diagnostic tool able to reduce complications associated with thoracocentesis and drainage. The RAPID score is being increasingly validated as a predictor for mortality but has not yet been proven useful to guide the treatment strategy and needs incorporation into prospective studies. Awaiting studies on outcome prediction and the comparison of an early surgical strategy versus drainage with intrapleural enzyme therapy, this article presents a summary of current knowledge of this complication.


Les infections de l'espace pleural surviennent chez environ 10 % des patients hospitalisés pour une pneumonie. Leur incidence est en augmentation, en parallèle du vieillissement de la population. L'échographie pleuropulmonaire est un outil diagnostique sensible, directement accessible au lit du malade et permettant de diminuer les complications du drainage grâce au guidage. Le score RAPID a été validé pour prédire la mortalité liée à l'infection de l'espace pleural mais son utilité pour sélectionner la meilleure stratégie thérapeutique reste encore à démontrer. Dans l'attente des résultats d'une étude prospective randomisée comparant une prise en charge chirurgicale précoce au drainage avec fibrinolyse, cet article présente l'état des connaissances concernant le traitement de cette affection.

RESUMO

BACKGROUND: Venous thromboembolism is a dreaded complication of hospitalised patients, with associated morbidity, mortality and increased healthcare costs. Previous studies have shown that pharmacological thromboprophylaxis, though effective, is inadequately administered in a large proportion of medical inpatients. STUDY AIMS: Our primary aim was to evaluate the contemporary adequacy of thromboprophylaxis in medical inpatients admitted to two Swiss hospitals (a university hospital and a regional hospital). The secondary aim was to estimate the 90-day incidence of relevant thrombotic and bleeding events. METHODS: In this prospective cohort, patients were recruited at the University Hospital of Geneva and the Regional Hospital of Lugano between September 2020 and February 2021 and followed for 90 days for venous thromboembolism and bleeding events. The adequacy of thromboprophylaxis (pharmacological and/or mechanical) at 24h after hospital admission was evaluated according to the simplified Geneva risk score for hospital-associated venous thromboembolism. RESULTS: Among 200 participants (100 at each site, mean age of 65 years), 57.5% were deemed at high risk of venous thromboembolism at admission. Thromboprophylaxis was adequate in 59.5% (95% CI 52.3-66.4%). Among high-risk and low-risk inpatients, thromboprophylaxis was adequate in 71.3% and 43.5%, respectively, with differences between sites. At 90 days, risks of adjudicated venous thromboembolism, major bleeding and mortality were 1.5%, 1.5% and 6.0%, respectively. CONCLUSION: Despite the extensive literature on thromboprophylaxis, the adequacy of thromboprophylaxis has not improved and remains insufficient among medical inpatients. Implementation and evaluation of clinical decision support systems are critically needed in this field. CLINICALTRIALS: gov number: NCT05306821.

RESUMO

Gout is a common complication occurring among inpatients, as factors affecting urate levels in blood and tissues are often modified by acute conditions. The control of chronic uricemia within recommended target values helps reduce the risk of flares. Joint aspiration is the gold standard for diagnosis, but ultrasound and dual-energy CT scan are reasonable alternatives. Acute and chronic treatments do not differ from those provided in outpatient care, although the increased prevalence of organ failures often require treatment adjustments. Active patient engagement, including therapeutic education during hospitalization, is essential for long-term disease control.


Lors d'un séjour hospitalier, les facteurs impactant la concentration sanguine et tissulaire d'urate sont souvent modifiés, augmentant le risque d'une crise de goutte. Le maintien de l'uricémie dans les cibles reconnues grâce à la poursuite des traitements contribue à réduire ce risque. La ponction articulaire est la méthode de référence pour établir le diagnostic, mais l'ultrason et le scanner à double énergie sont des alternatives fiables pour diagnostiquer une goutte. Les traitements aigu et chronique ne diffèrent pas de ceux pratiqués en ambulatoire, mais la fréquence augmentée d'insuffisances d'organes peut nécessiter l'adaptation des traitements. Pour assurer un contrôle de la maladie sur le long terme, il est essentiel d'impliquer le patient dans sa prise en charge, notamment par l'éducation thérapeutique dispensée pendant l'hospitalisation.

RESUMO

Acute heart failure is a leading cause of hospitalisations with an increasing economic and public health burden. Management of acute heart failure involves the use of diuretics to treat congestion and improve morbimortality. Despite current guidelines, numerous patients maintain congestion and often leave the hospital setting with incomplete volume depletion, leading to an increased risk of rehospitalisation. A recent multicentric randomised controlled trial studied the administration of acetazolamide in addition to standard care with loop diuretics in the acute setting. There was a significantly faster decongestion, based on a pragmatic clinical score, with very few side effects.


L'insuffisance cardiaque est la première cause d'hospitalisation dans les pays occidentaux, engendrant un coût médico-économique important. La prise en charge médicamenteuse de l'insuffisance cardiaque aiguë comprend l'administration de diurétiques afin de traiter la congestion et d'améliorer la morbimortalité. Toutefois, de nombreux patients présentent encore une congestion importante après plusieurs jours de traitement diurétique et rentrent à domicile avec une congestion résiduelle, augmentant le risque de récidive de décompensation cardiaque et par conséquent de ré-hospitalisation. Dans une étude randomisée multicentrique en double-aveugle, l'acétazolamide utilisé en adjonction d'un traitement diurétique de l'anse a permis une décongestion significativement plus rapide et efficace sans augmentation notable des effets indésirables.

RESUMO

Background: Thromboprophylaxis (TPX) prescription is recommended in medical inpatients categorized as high risk of venous thromboembolism (VTE) by validated risk assessment models (RAMs), but how various RAMs differ in categorizing patients in risk groups, and whether the choice of RAM influences estimates of appropriate TPX use is unknown. Objectives: To determine the proportion of medical inpatients categorized as high or low risk according to validated RAMs, and to investigate the appropriateness of TPX prescription. Methods: This is a prospective cohort study of acutely ill medical inpatients from 3 Swiss university hospitals. Participants were categorized as high or low risk of VTE by validated RAMs (ie, the Padua, the International Medical Prevention Registry on Venous Thromboembolism, simplified, and original Geneva scores). We assessed prescription of any TPX at baseline. We considered TPX prescription in high-risk and no TPX prescription in low-risk patients as appropriate. Results: Among 1352 medical inpatients, the proportion categorized as high risk ranged from 29.8% with the International Medical Prevention Registry on Venous Thromboembolism score to 66.1% with the original Geneva score. Overall, 24.6% were consistently categorized as high risk, and 26.3% as low risk by all 4 RAMs. Depending on the RAM used, TPX prescription was appropriate in 58.7% to 63.3% of high-risk (ie, 36.7%-41.3% underuse) and 52.4% to 62.8% of low-risk patients (ie, 37.2%-47.6% overuse). Conclusion: The proportion of medical inpatients considered as high or low VTE risk varied widely according to different RAMs. Only half of patients were consistently categorized in the same risk group by all RAMs. While TPX remains underused in high-risk patients, overuse in low-risk patients is even more pronounced.

RESUMO

INTRODUCTION: Burnout and low job satisfaction are increasing among the General Internal Medicine (GIM) workforce. Whether part-time compared to full-time clinical employment is associated with better wellbeing, job satisfaction and health among hospitalists remains unclear. MATERIALS AND METHODS: We conducted an anonymized cross-sectional survey among board-certified general internists (i.e. hospitalists) from GIM departments in 14 Swiss hospitals. Part-time clinical work was defined as employment of <100% as a clinician. The primary outcome was well-being, as measured by the extended Physician Well-Being Index (ePWBI), an ePWBI ≥3 indicating poor wellbeing. Secondary outcomes included depressive symptoms, mental and physical health, and job satisfaction. We compared outcomes in part-time and full time workers using propensity score-adjusted multivariate regression models. RESULTS: Of 199 hospitalists invited, 137 (69%) responded to the survey, and 124 were eligible for analysis (57 full-time and 67 part-time clinicians). Full-time clinicians were more likely to have poor wellbeing compared to part-time clinicians (ePWBI ≥3 54% vs. 31%, p = 0.012). Part-time compared to full-time clinical work was associated with a lower risk of poor well-being in adjusted analyses (odds ratio 0.20, 95% confidence interval 0.07-0.59, p = 0.004). Compared to full-time clinicians, there were fewer depressive symptoms (3% vs. 18%, p = 0.006), and mental health was better (mean SF-8 Mental Component Summary score 47.2 vs. 43.2, p = 0.028) in part-time clinicians, without significant differences in physical health and job satisfaction. CONCLUSIONS: Full-time clinical hospitalists in GIM have a high risk of poor well-being. Part-time compared to full-time clinical work is associated with better well-being and mental health, and fewer depressive symptoms.

RESUMO

INTRODUCTION: Pharmacological thromboprophylaxis slightly increases bleeding risk. The only risk assessment model to predict bleeding in medical inpatients, the IMPROVE bleeding risk score, has never been validated using prospectively collected outcome data. METHODS: We validated the IMPROVE bleeding risk score in a prospective multicenter cohort of medical inpatients. Primary outcome was in-hospital clinically relevant bleeding (CRB) within 14 days of admission, a secondary outcome was major bleeding (MB). We classified patients according to the score in high or low bleeding risk. We assessed the score's predictive performance by calculating subhazard ratios (sHRs) adjusted for thromboprophylaxis use, positive and negative predictive values (PPV, NPV), and the area under the receiver operating characteristic curves (AUC). RESULTS: Of 1155 patients, 8 % were classified as high bleeding risk. CRB and MB within 14 days occurred in 0.94 % and 0.47 % of low-risk and in 5.6 % and 3.4 % of high-risk patients, respectively. Adjusted for thromboprophylaxis, classification in the high-risk group was associated with an increased risk of 14-day CRB (sHR 4.7, 95 % confidence interval [CI] 1.5-14.5) and MB (sHR 4.9, 95%CI 1.0-23.4). PPV was 5.6 % and 3.4 %, while NPV was 99.1 % and 99.5 % for CRB and MB, respectively. The AUC was 0.68 (95%CI 0.66-0.71) for CRB and 0.73 (95%CI 0.71-0.76) for MB. CONCLUSION: The IMPROVE bleeding risk score showed moderate to good discriminatory power to predict bleeding in medical inpatients. The score may help identify patients at high risk of in-hospital bleeding, in whom careful assessment of the risk-benefit ratio of pharmacological thromboprophylaxis is warranted.

RESUMO

Catheter-associated urinary tract infections (CAUTI) are the most common type of healthcare-associated infection. They have a major impact on morbi-mortality and costs. Approximately 25 % of inpatients receive urinary catheters during their hospital stay. The most important risk factor for CAUTI is prolonged use of the catheter, and its appropriate use is on the Top Five list of the Choosing wisely campaign for the inpatient sector in Switzerland. Through the report of this clinical case, we review the guidelines for the appropriate use of urinary catheters, with a particular focus on reducing the risk of recurrent acute urinary retention after catheter ablation in men with benign prostatic hyperplasia.

RESUMO

Loop diuretics are strongly recommended by current guidelines for the treatment of acute heart failure. Intravenous furosemide can be administered either as a continuous infusion or as an intermittent bolus. The choice between these two routes is not always obvious in clinical practice. The understanding of their different mechanisms of action, as well as the notion of diuretic resistance, can help identify patients who may benefit from either of these two routes. This article aims at discussing these aspects and their pathophysiology, as well as summarizing the current body of evidence from randomized trials comparing continuous vs. intermittent administration of furosemide in acute heart failure.


Les diurétiques de l'anse sont fortement recommandés par les directives cliniques actuelles dans l'insuffisance cardiaque aiguë. Le furosémide intraveineux peut être administré sous formes continue et intermittente. En pratique clinique, le choix de la modalité d'administration n'est pas toujours évident. La compréhension de leur action et des mécanismes de résistance aux diurétiques permet d'identifier les situations cliniques qui répondent le mieux à l'une ou l'autre de ces méthodes d'administration. Cet article a pour but de discuter de ces différents aspects, notamment des mécanismes physiopathologiques en jeu, puis de synthétiser et évaluer le corpus d'évidences randomisées comparant ces deux modalités pour le traitement de l'insuffisance cardiaque aiguë.

RESUMO

Background: Hospitalized patients with COVID-19 suffered initially from high rates of venous thromboembolism (VTE), with possible associations between therapeutic anticoagulation and better clinical outcomes in observational studies. Objective: To test whether therapeutic anticoagulation improves clinical outcomes in severe COVID-19. Patients/Methods: In this multicenter, open-label, randomized controlled trial, we recruited acutely ill medical COVID-19 patients with D-dimer >1000 ng/ml or critically ill COVID-19 patients in four Swiss hospitals, from April 2020 until June 2021, with a 30-day follow-up. Participants were randomized to in-hospital therapeutic anticoagulation versus low-dose anticoagulation in acutely ill participants/intermediate-dose anticoagulation in critically ill participants, with enoxaparin or unfractionated heparins. The primary outcome was a centrally adjudicated composite of 30-day all-cause mortality, VTE, arterial thrombosis, and disseminated intravascular coagulopathy (DIC), with screening for proximal deep vein thrombosis. Results: Among 159 participants, 55.3% were critically ill and 94.3% received corticosteroids. Before study inclusion, pulmonary embolism had been excluded in 71.7%. The primary outcome occurred in 4/79 participants randomized to therapeutic anticoagulation and 4/80 to low/intermediate anticoagulation (5.4% vs. 5.0%; risk difference +0.4%; adjusted hazard ratio 0.76, 95% confidence interval 0.18-3.21), including three deaths in each group. All primary outcomes and major bleeding (n = 3) occurred in critically ill participants. There was no asymptomatic proximal deep vein thrombosis and no difference in major bleeding. Conclusions: Among patients with severe COVID-19 treated with corticosteroids and with exclusion of pulmonary embolism at hospital admission for most, risks of mortality, thrombotic outcomes, and DIC were low at 30 days. The lack of benefit of therapeutic anticoagulation was too imprecise for definite conclusions.

RESUMO

The definition of unintentional weight loss (UWL) is heterogeneous and most commonly used as a UWL of >5% over the past 6 months. The differential diagnosis of UWL is very broad and encompasses non-medical causes, somatic illnesses, and psychiatric conditions. One of the feared diagnoses remains the presence of an underlying cancer. It is observed that UWL is more associated with certain types of cancer, in particular digestive. The primary workup for UWL should begin with a history and a detailed physical examination searching for associated symptoms or signs. The age, sex and smoking status are factors to be considered in particular. Management of UWL does not meet established recommendations and should be guided by relevant signs and symptoms. Future studies are necessary, in particular to clarify the place of imaging in the diagnostic process.


La définition de la perte de poids involontaire (PPI) est hétérogène, celle souvent retenue est une PPI > 5 % en 6 mois. Le diagnostic différentiel est très large et prend en compte des causes variées, dont la présence redoutée d'un cancer sous-jacent. Elle est plus souvent associée à certains types de cancer, notamment digestifs. Son bilan primaire commence par une anamnèse et un examen clinique détaillés à la recherche de symptômes associés. L'âge, le sexe et le tabagisme sont des facteurs à prendre en compte. Sa prise en charge ne répond pas à des recommandations clairement établies, mais est guidée par les symptômes associés. De futures études sont nécessaires, notamment pour clarifier la place de l'imagerie dans la démarche diagnostique.

RESUMO

BACKGROUND: Serological assays detecting anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies are being widely deployed in studies and clinical practice. However, the duration and effectiveness of the protection conferred by the immune response remains to be assessed in population-based samples. To estimate the incidence of newly acquired SARS-CoV-2 infections in seropositive individuals as compared to seronegative controls, we conducted a retrospective longitudinal matched study. METHODS: A seroprevalence survey including a representative sample of the population was conducted in Geneva, Switzerland, between April and June 2020, immediately after the first pandemic wave. Seropositive participants were matched one-to-two to seronegative controls, using a propensity-score including age, gender, immunodeficiency, body mass index (BMI), smoking status, and education level. Each individual was linked to a state-registry of SARS-CoV-2 infections. Our primary outcome was confirmed infections occurring from serological status assessment to the end of the second pandemic wave (January 2021). RESULTS: Among 8344 serosurvey participants, 498 seropositive individuals were selected and matched with 996 seronegative controls. After a mean follow-up of 35.6 (standard deviation [SD] 3.2) weeks, 7 out of 498 (1.4%) seropositive subjects had a positive SARS-CoV-2 test, of whom 5 (1.0%) were classified as reinfections. In contrast, the infection rate was higher in seronegative individuals (15.5%, 154/996) during a similar follow-up period (mean 34.7 [SD 3.2] weeks), corresponding to a 94% (95% confidence interval [CI]: 86%- 98%, P < .001) reduction in the hazard of having a positive SARS-CoV-2 test for seropositives. CONCLUSIONS: Seroconversion after SARS-CoV-2 infection confers protection against reinfection lasting at least 8 months. These findings could help global health authorities establishing priority for vaccine allocation.

RESUMO

2020: annus horribilis for hospital medicine? The past year, notable because of the current pandemic, has had a profound impact on multiple aspects of medical practice. Just as all medical staff and the general population, hospital internists were put under immense strain in 2020. This year has more than ever reinforced our belief in the importance of keeping a critical and scientific eye on the mass of new studies and data produced every year. The internists of the HUG propose a critical review of selected recent publications that may influence our daily management of patients.


2020 : annus horribilis pour la médecine hospitalière ? L'année écoulée, marquée par la pandémie en cours, a eu un impact majeur sur de multiples aspects de notre pratique. Comme l'ensemble du monde médico-soignant et de la population, les internistes hospitaliers ont été mis à rude épreuve en 2020. Cette année a plus que jamais renforcé notre conviction de l'importance de porter un regard scientifique sur la masse de nouveautés qui surviennent chaque année. Les internistes hospitaliers des HUG vous proposent de partager leur vision critique de publications scientifiques récentes utiles pour notre pratique quotidienne.

RESUMO

BACKGROUND: Dapagliflozin, a sodium-glucose cotransporter 2 inhibitor, was shown in the DAPA-HF study to reduce the risk of worsening heart failure or death in symptomatic patients with left ejection fraction <40%, irrespective of diabetes. The aim of this study was to evaluate eligibility status for dapagliflozin in non-selected patients hospitalized for acute decompensated heart failure (ADHF), as well as prognostic implications of this status. MATERIALS AND METHODS: Analysis of 815 patients recruited in a prospective cohort of acute heart failure at the University Hospitals of Geneva, consisting of consecutive patients admitted with ADHF. Eligibility for dapagliflozin was determined using criteria described DAPA-HF. RESULTS: Of 815 patients, 220 (27%) were eligible for dapagliflozin treatment. In survival analysis, patients who were eligible for dapagliflozin had better clinical outcomes with respect to all-cause mortality and rehospitalization as compared to those who were not eligible. In multivariate analysis, the hazard ratio for all-cause mortality or readmission in patients eligible for dapagliflozin was 0.82 (95% CI 0.68-0.999, P = .049) as compared to the non-eligible. CONCLUSIONS: Using DAPA-HF criteria, only 27% of non-selected patients admitted for ADHF are theoretically eligible for dapagliflozin. This eligibility for dapagliflozin is associated with better outcomes. Further evaluation of the benefits of dapagliflozin in selected HF patients may be of interest.
