Long-term monitoring and treatment of venous thromboembolic disease: recommendations of the Thromboembolic Disease Group of the Spanish Society of Internal Medicine 2024

Venous thromboembolim (VTE) is a highly prevalent condition that requires long-term monitoring and treatment. This monitoring includes: 1) completing the etiological study and determining the risk of VTE recurrence; 2) establishing the optimal duration of anticoagulant treatment, as well as the type of therapy and its dosage; 3) estimating the risk of bleeding, and 4) identifying the occurrence of chronic complications. This consensus document, prepared by the VTE Group of the Spanish Society of Internal Medicine (SEMI), aims to update and establish consensus recommendations on these aspects. The document focuses on four aspects of management: the first includes risk factors for VTE recurrence after an unprovoked VTE episode and describes the predictive scores of VTE recurrence; the second focuses on risk factors for bleeding; the third provides recommendations for long-term follow-up in VTE, addressing specific considerations for screening chronic thromboembolic pulmonary hypertension and post-thrombotic syndrome of the lower limbs; and the fourth provides guidance on the optimal duration of extended anticoagulant treatment, as well as the type of therapy and its dosage. For each area, an exhaustive literature review was conducted, analyzing the updated VTE clinical guidelines and recent studies. This document is intended to be a guide in the long-term management of VTE based on the most current knowledge.

Executive summary of the Spanish consensus for the diagnosis, management, and follow-up of primary hyperaldosteronism.

Primary hyperaldosteronism (PH) is the most common cause of secondary hypertension (HTN) and is associated with a higher cardiometabolic risk than essential HTN. Nevertheless, PH remains clearly underdiagnosed. An early diagnosis and adequate treatment of this disease are essential to reduce the cardiometabolic morbimortality associated with aldosterone excess. PH follow-up is equally essential; however, there is little consensus on how it should be performed, being a topic rarely mentioned by the different clinical practice guidelines. The aim of this executive summary is to summarize the recommendations made in the Spanish consensus of PH for the diagnosis, management, and follow-up of these patients. The Spanish consensus was reached from a multidisciplinary perspective through a nominal group consensus approach by experts from the Spanish Society of Endocrinology and Nutrition (SEEN), the Spanish Society of Cardiology (SEC), the Spanish Society of Nephrology (SEN), the Spanish Society of Internal Medicine (SEMI), the Spanish Society of Radiology (SERAM), the Spanish Society of Vascular and Interventional Radiology (SERVEI), the Spanish Society of Laboratory Medicine (SEQC(ML)), the Spanish Society of Anatomic-Pathology (EAP), and the Spanish Association of Surgeons (AEC).

The RICA-2 registry: design and baseline characteristics of the first 1,000 patients

Background and objectiveHeart failure (HF) is a syndrome of epidemic proportions and one of the main reasons for hospital admission. Patient registries provide real-world clinical practice information which is complementary to clinical trials. RICA-2 is a registry of the Spanish Society of Internal Medicine. Its main goal is to know the clinical and epidemiological characteristics and prognostic factors of patients with HF treated in Internal Medicine Departments. The objective of this study is to present the design of the RICA-2, the baseline characteristics of the first 1000 patients included and their comparison with those of the historical cohort of the RICA registry. MethodsObservational, multicentre and prospective study of patients with HF with the following inclusion criteria: age equal to or greater than 18 years old, diagnosis of HF according to the European Guidelines, indistinct inclusion in decompensation or stable phase, of patients with de novo HF or chronic HF, regardless of left ventricular ejection fraction, aetiology and comorbidities. ResultsRICA-2 patients have advanced age (83 years old) and 51% are women. The comorbidity burden is higher than in the RICA registry (5 points in the Charlson comorbidity index), with predominating chronic decompensated HF (74%), hypertensive aetiology (39%) and preserved ejection fraction (52%). Most patients are pre-frail or vulnerable and are at risk of malnutrition. ConclusionThe RICA-2 represents a contemporary cohort of patients that will provide us with clinical, epidemiological and prognostic information on patients with acute and chronic HF treated in Internal Medicine.

Diagnosis and treatment of deep vein thrombosis of the lower and upper limbs. 2024 recommendations of the venous thromboembolism group of the Spanish Society of Internal Medicine

Deep vein thrombosis (DVT) of the limbs is a common disease and causes significant morbidity and mortality. It is frequently the prelude to pulmonary embolism (PE), it can recur in 30% of patients and in 25–40% of cases they can develop post-thrombotic syndrome (PTS), with a significant impact in functional status and quality of life. This document contains the recommendations on the diagnosis and treatment of acute DVT from the Thromboembolic Disease group of the Spanish Society of Internal Medicine (SEMI).PE and thrombosis of unusual venous territories (cerebral, renal, mesenteric, superficial, etc.) are outside its scope, as well as thrombosis associated with catheter and thrombosis associated with cancer, which due to their peculiarities will be the subject of other positioning documents of the Thromboembolic Disease group of the Spanish Society of Internal Medicine (SEMI).

Practical consensus for the treatment and follow-up of primary aldosteronism: a multidisciplinary consensus document.

Primary aldosteronism (PA) is the most frequent cause of secondary hypertension and is associated with a higher cardiometabolic risk than essential hypertension. The aim of this consensus is to provide practical clinical recommendations for its surgical and medical treatment, pathology study and biochemical and clinical follow-up, as well as for the approach in special situations like advanced age, pregnancy and chronic kidney disease, from a multidisciplinary perspective, in a nominal group consensus approach of experts from the Spanish Society of Endocrinology and Nutrition (SEEN), Spanish Society of Cardiology (SEC), Spanish Society of Nephrology (SEN), Spanish Society of Internal Medicine (SEMI), Spanish Radiology Society (SERAM), Spanish Society of Vascular and Interventional Radiology (SERVEI), Spanish Society of Laboratory Medicine (SEQC(ML)), Spanish Society of Anatomic-Pathology and Spanish Association of Surgeons (AEC).

Screening and diagnosis of primary aldosteronism. Consensus document of all the Spanish Societies involved in the management of primary aldosteronism.

Primary aldosteronism (PA) is the most frequent cause of secondary hypertension (HT), and is associated with a higher cardiometabolic risk than essential HT. However, PA remains underdiagnosed, probably due to several difficulties clinicians usually find in performing its diagnosis and subtype classification. The aim of this consensus is to provide practical recommendations focused on the prevalence and the diagnosis of PA and the clinical implications of aldosterone excess, from a multidisciplinary perspective, in a nominal group consensus approach by experts from the Spanish Society of Endocrinology and Nutrition (SEEN), Spanish Society of Cardiology (SEC), Spanish Society of Nephrology (SEN), Spanish Society of Internal Medicine (SEMI), Spanish Radiology Society (SERAM), Spanish Society of Vascular and Interventional Radiology (SERVEI), Spanish Society of Laboratory Medicine (SEQC(ML)), Spanish Society of Anatomic-Pathology, Spanish Association of Surgeons (AEC).

Consensus on the approach to hydrosaline overload in acute heart failure. SEMI/SEC/S.E.N. recommendations

Most of the signs and symptoms of heart failure can be explained by fluid overload, which is also related to disease progression. Fluid overload is a complex phenomenon that extends beyond increased intravascular pressures and poses challenges for accurate diagnosis and effective treatment. Current recommendations advise a multiparametric approach, including clinical data (symptoms/signs), imaging tests, and biomarkers. This article proposes a practical therapeutic approach to managing hydrosaline overload in heart failure in both inpatient and outpatient settings. This document is an initiative of the Spanish Society of Internal Medicine (SEMI) in collaboration with the Spanish Society of Cardiology (SEC) and the Spanish Society of Nephrology (S.E.N.).

Consensus document on the management of hyperkalemia

Hyperkalaemia is a common electrolyte imbalance with potentially serious short-, medium- and long-term consequences on morbidity and mortality rates and the use of national health service resources. The fact that different medical specialities can manage hyperkalaemia makes it important to have a unified approach, and the recent availability of new specific drug treatments means that the approach needs to be updated. This consensus document from the scientific societies most directly involved in the management of hyperkalaemia (Sociedad Española de Cardiología [Spanish Society of Cardiology], Sociedad Española de Endocrinología y Nutrición [Spanish Society of Endocrinology and Nutrition], Sociedad Española de Medicina Interna [Spanish Society of Internal Medicine], Sociedad Española de Medicina de Urgencias y Emergencias [Spanish Society of Accident and Emergency Medicine] and Sociedad Española de Nefrología [Spanish Society of Nephrology]) first of all reviews basic aspects of potassium balance and blood potassium. Then it goes on to focus on the concept, epidemiology, pathophysiology and diagnostic and therapeutic approaches to hyperkalaemia. The available evidence and the main published studies have been reviewed with the aim of providing a useful tool in the multidisciplinary approach to patients with hyperkalaemia.

What Ethics Support for Resolving Ethical Conflicts Do Internists Use in Spanish Hospitals?

Background Ethical conflicts generate difficulties in daily clinical activity. Which methods of ethical advice are most frequently used to resolve them among Spanish doctors has not been studied. The objective of this study is to describe what methods hospital internal medicine physicians in Spain use to resolve their ethical doubts and which they consider most useful. Design A cross-sectional observational study was conducted through a voluntary and anonymous survey and distributed through an ad hoc platform of the Spanish Society of Internal Medicine. Measures We measured methods by which to resolve doubts, types of tools sought, frequency of consulting the Clinical Ethics Committees, and satisfaction with resolution of ethical issues. Results Of 261 internists surveyed, 86 per cent resolve their ethical doubts with assistance, the most frequently used method being consultation with colleagues (58.6 per cent), followed by using specific protocols or guides (11.8 per cent) and consultation with experts in bioethics (9.6 per cent). The most preferred tools are the creation of protocols (30.3 per cent) and the establishment of a consultant/expert in bioethics (27.8 per cent). Conclusions Internists in Spain usually seek assistance to resolve their ethical doubts. Consulting colleagues is the most frequently adopted method. The majority regard tools to resolve ethical conflicts as necessary, seeking above all protocols and consultants/experts in bioethics.

Treatment variability and its relationships to outcomes among patients with Wernicke's encephalopathy: A multicenter retrospective study

BackgroundDespite guidelines and recommendations, Wernicke's encephalopathy (WE) treatment lacks evidence, leading to clinical practice variability. AimsGiven the overall lack of information on thiamine use for WE treatment, we analyzed data from a large, well-characterized multicenter sample of patients with WE, examining thiamine dosages; factors associated with the use of different doses, frequencies, and routes; and the influence of differences in thiamine treatment on the outcome. MethodsThis retrospective study was conducted with data from 443 patients from 21 centers obtained from a nationwide registry of the Spanish Society of Internal Medicine (from 2000 to 2012). Discharge codes and Caine criteria were applied for WE diagnosis, and treatment-related (thiamine dosage, frequency, and route of administration) demographic, clinical, and outcome variables were analyzed. ResultsWe found marked variability in WE treatment and a low rate of high-dose intravenous thiamine administration. Seventy-eight patients out of 373 (20.9%) received > 300mg/day of thiamine as initial dose. Patients fulfilling the Caine criteria or presenting with the classic WE triad more frequently received parenteral treatment. Delayed diagnosis (after 24h hospitalization), the fulfillment of more than two Caine criteria at diagnosis, mental status alterations, and folic acid deficiency were associated significantly with the lack of complete recovery. Malnutrition, reduced consciousness, folic acid deficiency, and the lack of timely thiamine treatment were risk factors for mortality. ConclusionsOur results clearly show extreme variability in thiamine dosages and routes used in the management of WE. Measures should be implemented to ensure adherence to current guidelines and to correct potential nutritional deficits in patients with alcohol use disorders or other risk factors for WE.

Impacto de la fragilidad en la supervivencia intrahospitalaria en pacientes mayores con infección por COVID-19: la importancia de su identificación temprana. Registro Nacional SEMI-COVID

BackgroundEmerging evidence suggests that frailty may be a significant predictor of poor outcomes in older individuals hospitalized due to COVID-19. This study aims to determine the prognostic value of frailty on intrahospital patient survival. MethodsThis observational, multicenter, nationwide study included patients aged 70 years and older who were hospitalized due to COVID-19 in Spain between March 1 and December 31, 2020. Patient data were obtained from the SEMI-COVID-19 Registry of the Spanish Society of Internal Medicine. Frailty was assessed using the Clinical Frailty Scale. The primary outcome was hospital survival. Cox proportional hazards models were used to assess predictors of survival. ResultsA total of 1878 participants (52% men and 48% women) were included, with 1351 (71.9%) survivors and 527 (28.1%) non-survivors. The non-survivor group had higher mean age (83.5 vs. 81 years), comorbidities (6.3 vs. 5.3 points on the Charlson index), degree of dependency (26.8% vs. 12.4% severely dependent patients), and frailty (34.5% vs. 14.7% severely frail patients) compared to survivors. However, there were no differences in terms of sex. Our results demonstrate that a moderate–severe degree of frailty is the primary factor independently associated with shorter survival (HR 2.344; 1.437-3.823; p < 0.001 for CFS 5-6 and 3.694; 2.155–6.330; p < 0.001 for CFS 7-9). ConclusionFrailty is the main predictor of adverse outcomes in older patients with COVID-19. The utilization of tools such as the Clinical Frailty Scale is crucial for early detection in this population.

RECALMIN IV. Evolution in the activity of internal medicine units of the National Health System (2008–2021)

AimsThis work aims to analyze the structure, activity, and outcomes of internal medicine units and departments (IMU) of the Spanish National Health System (SNHS) and to analyze the challenges for the specialty and propose policies for improvement. It also aims to compare the results from the 2021 RECALMIN survey with IMU surveys from previous years (2008, 2015, 2017, 2019). MethodsThis work is a cross-sectional, descriptive study of IMUs in acute care general hospitals of the SNHS that compares data from 2020 with previous studies. The study variables were collected through an ad hoc questionnaire. ResultsBetween 2014 and 2020, hospital occupancy and discharges by IMU increased (annual mean of 4% and 3.8%, respectively), as did hospital cross-consultation and initial consultation rates (2.1% in both cases). E-consultations increased notably in 2020. Risk-adjusted mortality and length of hospital stay did not show significant changes from 2013−2020. Progress in the implementation of good practices and systematic care for complex chronic patients was limited. A consistent finding in RECALMIN surveys was the variability among IMUs in terms of resources and activity, though no statistically significant differences were found in regard to outcomes. ConclusionsThere is considerable room for improvement in the operation of IMUs. The reduction in unjustified variability in clinical practice and inequities in health outcomes are a challenge for IMU managers and the Spanish Society of Internal Medicine.

Mortality risk factors in patients with SARS-CoV-2 infection and atrial fibrillation: Data from the SEMI-COVID-19 registry

IntroductionAtrial fibrillation and associated comorbidities pose a risk factor for mortality, morbidity and development of complications in patients admitted for COVID-19. ObjectivesTo describe the clinical, epidemiological, radiological and analytical characteristics of patients with AF admitted for COVID-19 in Spain. Secondarily, we aim to identify those variables associated with mortality and poor prognosis of COVID-19 in patients with AF. MethodsRetrospective, observational, multicenter, nationwide, retrospective study of patients hospitalized for COVID-19 from March 1 to October 1, 2020. Data were obtained from the SEMI-COVID-19 Registry of the Spanish Society of Internal Medicine (SEMI) in which 150 Spanish hospitals participate. ResultsBetween March 1 and October 1, 2020, data from a total of 16,461 patients were entered into the SEMI-COVID-19 registry. 1,816 (11%) had a history of AF and the number of deaths among AF patients amounted to 738 (41%). Regarding clinical characteristics, deceased patients were admitted with a higher heart rate (88.38 vs 84.95; p > 0.01), with a higher percentage of respiratory failure (67.2% vs 20.1%; p < 0.01) and high tachypnea (58% vs 30%; p < 0.01). The comorbidities that presented statistically significant differences in the deceased group were: age, hypertension and diabetes with target organ involvement. There was also a higher prevalence of a history of cardiovascular disease in the deceased. On multivariate analysis, DOACs treatment had a protective role for mortality (OR:0,597) IC (0,402-0,888 ; p = 0.011). ConclusionsPrevious treatment with DOACs and DOACs treatment during admission seem to have a protective role in patients with AF, although this fact should be verified in prospective studies.

Clinical Characteristics and Prognostic Relevance of Different Types of Caregivers for Elderly Patients with Acute Heart Failure-Analysis from the RICA Registry.

Background: Patients with heart failure encompass a heterogeneous group, but they are mostly elderly patients with a large burden of comorbid conditions. Objective: The aim of this study was to compare the clinical characteristics and the prognostic impact on hospital admissions and mortality in a population of patients with HF with different types of caregivers (family members, professionals, and the patient himself). Methods: We conducted an observational study from a prospective registry. Patients from the National Registry of Heart Failure (RICA), which belongs to the Working Group on Heart Failure and Atrial Fibrillation of the Spanish Society of Internal Medicine (SEMI), were included. Patients with heart failure were classified, according to the type of main caregiver, into four groups: the patient himself/herself, a partner, children, or a professional caregiver. A bivariable analysis was performed between the clinical, analytical, therapeutic, and prognostic characteristics of the different groups. The endpoints of the study were all-cause mortality at 1 year; mortality at 120 days; and the readmission rate for HF at 30 days, 120 days, and 1 year of follow-up. In all cases, the level of statistical significance was set at p < 0.05. Results: A total of 2147 patients were enrolled in this study; women represented 52.4%, and the mean age was 81 years. The partner was the caregiver for 703 patients, children were caregivers for 1097 patients, 199 patients had a professional caregiver, and only 148 patients were their own caregivers. Women were more frequently cared for by their children (65.8%) or a professional caregiver (61.8%); men were more frequently cared for by their spouses (68.7%) and more frequently served as their own caregivers (59.5%) (p < 0.001). No statistically significant differences were observed in relation to readmissions or mortality at one year of follow-up between the different groups. A lower probability of readmission and death was observed for patients who received care from a partner or children/relative, with log-rank scores of 11.2 with p= 0.010 and 10.8 with p = 0.013. Conclusions: Our study showed that the presence of a family caregiver for elderly patients with heart failure was associated with a lower readmission rate and a lower mortality rate at 120 days of follow-up. Our study also demonstrated that elderly patients with good cognitive and functional status can be their own caregivers, as they obtained good health outcomes in terms of readmission and mortality. More prospective studies and clinical trials are needed to evaluate the impact of different types of caregivers on the outcomes of patients with heart failure.

Prognostic Significance of the PROFUND Index on One Year Mortality in Acute Heart Failure: Results from the RICA Registry.

Background: Heart failure (HF) is a syndrome with high prevalence, mainly affecting elderly patients, where the presence of associated comorbidities is of great importance. Methods: An observational study from a prospective registry was conducted. Patients identified from the National Registry of Heart Failure (RICA), which belongs to the Working Group on Heart Failure and Atrial Fibrillation of the Spanish Society of Internal Medicine (SEMI), were included. The latter is a prospective, multicenter registry that has been active since 2008. It includes individual consecutive patients over 50 years of age with a diagnosis of HF at hospital discharge (acute decompensated or new-onset HF). Results: In total, 5424 patients were identified from the registry. Forty-seven percent were men and mean left ventricular ejection fraction (LVEF) was 51.4%; 1132 had a score of 0 to 2 according to the PROFUND index, 3087 had a score of 3 to 6, and 952 patients had a score of 7 to 10 points. In the sample, 252 patients had a score above 11 points. At the end of the year of follow-up, 61% of the patients died. This mortality increased proportionally as the PROFUND index increased, specifically 75% for patients with PROFUND greater than 11. The Kaplan-Meier survival curve shows that survival at one year progressively decreases as the PROFUND index value increases. Thus, subjects with scores greater than seven (intermediate-high and high-risk) presented the worst survival with a log rank of 0.96 and a p < 0.05. In the regression analysis, we found a higher risk of death from any cause at one year in the group with the highest risk according to the PROFUND index (score greater than 11 points (HR 1.838 (1.410–2.396)). Conclusions: The PROFUND index is a good index for predicting mortality in patients admitted for acute HF, especially in those subjects at intermediate to high risk with scores above seven. Future studies should seek to determine whether the PROFUND index score is simply a prognostic marker or whether it can also be used to make therapeutic decisions for those subjects with very high short-term mortality.
