Epidemiology, clinical profile, management, and two-year risk complications among patients with chronic kidney disease in Spain

Objectives: To describe the epidemiology, clinical profile, treatments, and to determine cardiovascular and renal outcomes after two years of follow-up in a contemporary chronic kidneay disease (CKD) population in Spain. This was also analyzed among the DAPA-CKD-like population (patients who met most inclusion criteria of DAPA-CKD trial). Methods: Observational, retrospective, population-based study using BIG-PAC database. The CKD population was defined as patients >= 18 years, with at least one diagnostic code of CKD prior to the index date (January 1st, 2018). CKD was defined as estimated glomerular filtration rate (eGFR) 30 mg/g. Results: We identified 56,435 CKD patients after exclusions (76.4 years, 52.2% men, urine-album into-creatinine ratio 390.8 mg/g, eGFR 49.7 mL/min/1.73 m(2)). CKD prevalence was4.91% and incidence 2.10 per 1000 patient-years. Regarding treatments, 69.2% were taking renin-angiotensin system inhibitors (only 4.2% at maximal doses) and 3.5% of diabeticpatients SGLT-2 inhibitors. During the two years of follow-up, rates of heart failure, all-cause death, myocardial infarction, stroke, and CKD were 17.9, 12.1, 7.2, 6.3, and 5.9 events per 100 patient-years, respectively. During this period, 44% of patients were hospitalized, and 6.8% died during hospitalization. Cardiovascular outcomes were more common in the DAPACKD-like population. Conclusions: In Spain, CKD population is older and comorbidities, including diabetes and heart failure, are common. Cardiovascular and renal outcomes are frequent. There is room for improvement in CKD management, particularly through the use of drugs with proven cardiovascular and renal benefit. (C) 2021 Sociedad Espanola de Nefrolog ' ia.

Costs and healthcare utilisation of patients with heart failure in Spain

Background: Increasing the knowledge about heart failure (HF) costs and their determinants is important to ascertain how HF management can be optimized, leading to a significant decrease of HF costs. This study evaluated the cumulative costs and healthcare utilisation in HF patients in Spain. Methods: Observational, retrospective, population-based study using BIG-PAC database, which included data from specialized and primary care of people ≥18 years, from seven autonomous communities in Spain, who received care for HF between 2015 and 2019. The healthcare and medication costs were summarized on a yearly basis starting from the index date (1st January 2015), and then cumulatively until 2019. Results: We identified 17,163 patients with HF (year 2015: mean age 77.3 ± 11.8 years, 53.5% men, 51.7% systolic HF, 43.6% on NYHA functional class II). During the 2015–2019 period, total HF associated costs reached 15,373 Euros per person, being cardiovascular disease hospitalizations the most important determinant (75.8%), particularly HF hospitalizations (51.0%). Total medication cost accounted for 7.0% of the total cost. During this period, there was a progressive decrease of cardiovascular disease hospital costs per year (from 2834 Euros in 2015 to 2146 Euros in 2019, P < 0.001), as well as cardiovascular and diabetic medication costs. Conclusions: During the 2015–2019 period, costs of HF patients in Spain were substantial, being HF hospitalizations the most important determinant. Medication costs represented only a small proportion of total costs. Improving HF management, particularly through the use of drugs that reduce HF hospitalization may be helpful to reduce HF burden

Costs and healthcare utilisation of patients with chronic kidney disease in Spain

Background: Data about the impact of chronic kidney disease (CKD) on health care costs in Spain are scarce This study was aimed to evaluate cumulative costs and healthcare utilisation in CKD in Spain. Methods: Observational, retrospective, population-based study, which included adults who received care for CKD between 2015 and 2019. Healthcare and medication costs were summarized on a yearly basis starting from the index date (1st January 2015), and then cumulatively until 2019. Results: We identified 44,214 patients with CKD (year 2015: age 76.4 ± 14.3 years, 49.0% women, albumin-to-creatinine ratio 362.9 ± 176.8 mg/g, estimated glomerular filtration rate 48.7 ± 13.2 mL/min/1.73 m2). During the 2015-2019 period, cumulative CKD associated costs reached 14,728.4 Euros, being cardiovascular disease hospitalizations, particularly due to heart failure and CKD, responsible for 77.1% of costs. Total medication cost accounted for 6.6% of the total cost. There was a progressive decrease in cardiovascular disease hospital costs per year (from 2741.1 Euros in 2015 to 1.971.7 Euros in 2019). This also occurred with cardiovascular and diabetic medication costs, as well as with the proportion of hospitalizations and mortality. Costs and healthcare resources use were higher in the DAPA-CKD like population, but also decreased over time. Conclusions: Between 2015 and 2019, costs of patients with CKD in Spain were high, with cardiovascular hospitalizations as the key determinant. Medication costs were responsible for only a small proportion of total CKD costs. Improving CKD management, particularly with the use of cardiovascular and renal protective medications may be helpful to reduce CKD burden

The social return on investment of a new approach to heart failure in the Spanish National Health System

Aims: We aim to agree on a set of proposals to improve the current management of heart failure (HF) within the Spanish National Health System (SNHS) and apply the social return on investment (SROI) method to measure the social impact that these proposals would generate. Methods and results: A multidisciplinary working team of 16 experts was set up, with representation from the main stakeholders regarding HF: medical specialists (cardiologists, internal medicine physicians, general practitioners, and geriatric physicians), nursing professionals, health management professionals, patients, and informal caregivers. This team established a set of proposals to improve the management of HF according to the main areas of HF care: emergency and hospitalization, primary care, cardiology, and internal medicine. A forecast-type SROI method, with a 1-year time frame, was applied to measure the social impact resulting from the implementation of these proposals. The required investment and social return were estimated and summarized into a ratio indicating how much social return could be generated for each euro invested. Intangible returns were included and quantified through financial proxies. The approach to improve the management of HF consisted of 28 proposals, including the implementation of a case management nurse network, standardization of operational protocols, psychological support, availability of echocardiography machines at emergency departments, stationary units and primary care, early specialist visits after hospital discharge, and cardiac rehabilitation units, among others. These proposals would benefit not only patients and their informal caregivers but also the SNHS. Regarding patients, proposals would increase their autonomy in everyday activities, decrease anxiety, increase psychological and physical well-being, improve pharmacological adherence and self-care, enhance understanding of the disease, delay disease progression, expedite medical assessment, and prevent the decrease in work productivity associated with HF management. Regarding informal caregivers, proposals would increase their quality of life; improve their social, economic, and emotional well-being; and reduce their care burden. The SNHS would benefit from shorter stays of HF patients at intensive care units and reduction of hospitalizations and admissions to emergency departments. The investment needed to implement these proposals would amount to €548m and yield a social return of €1932m, that is, €3.52 for each euro invested. Conclusions: The current management of HF could be improved by a set of proposals that resulted in an overall positive social return, varying between areas of analysis. This may guide the allocation of healthcare resources and improve the quality of life of patients with HF

Benefit of tolvaptan in the management of hyponatraemia in patients with diuretic‐refractory congestive heart failure: the SEMI‐SEC project

Aims: Hyponatraemia is an electrolyte disorder that occurs in advanced congestive heart failure (HF) and worsens prognosis. We explored the usefulness of tolvaptan, which has shown promising results in the treatment of this condition. Methods and results: This study is based on a retrospective national registry (2011-15) of patients hospitalized with refractory HF and hyponatraemia who agreed to receive tolvaptan when standard treatment was ineffective. The benefit of tolvaptan was analysed according to the following criteria: normalization ([Na+] >= 135mmol/L) or increased sodium levels [Na+] >= 4mEq/L on completion of treatment, and increase in urine output by 300 or 500mL at 48h. Factors associated with tolvaptan benefit were explored. A total of 241 patients were included, 53.9% of whom had ejection fraction = 4mEq/L and/or +300mL in urine output (54.4% both). Conclusions: An increase in sodium levels and/or improvement in urine output was observed in patients admitted for HF and refractory hyponatraemia under tolvaptan treatment. Tolvaptan may be useful in this setting, in which no effective proven alternatives are available

Outcomes and factors associated with mortality in patients with atrial fibrillation and heart failure: FARAONIC study

Background: Heart failure (HF) and atrial fibrillation (AF) are common and coexistent conditions. Hypothesis: To investigate the adverse events and mortality risk factors in patients with AF and HF treated with rivaroxaban in Spain. Methods: Multicenter, prospective and observational study with a follow-up of 2 years, that included adults, with a diagnosis of nonvalvular AF and chronic HF, anticoagulated with rivaroxaban at least 4 months before being enrolled. Results: A total of 672 patients from 71 Spanish centers were recruited, of whom 658 (97.9%) were included in the safety analysis and 552 (82.1%) in the per protocol analysis. At baseline, the mean age was 73.7 +/- 10.9 years, 65.9% were male, 51.3% had HF with preserved ejection fraction and 58.7% were on New York Heart Association functional class II. CHA2DS2-VASc was 4.1 +/- 1.5. During the follow-up, 11.6% of patients died and around one-quarter of patients were hospitalized or visited the emergency department, being HF worsening/progression the main cause (51.1%), with a 2.9% of thromboembolic events and 2.0% of acute coronary syndromes. Major bleeding occurred in 3.1% of patients, with 0.5% experiencing intracranial bleeding but no fatalities. Compliance with HF treatment was associated with a lower risk of death (hazard ratio: 0.092; 95% confidence interval: 0.03-0.31). Conclusions: Among patients with HF and AF anticoagulated with rivaroxaban, incidences of thromboembolic or hemorrhagic complications were low. The most important factor for improving survival was compliance with HF drugs, what strengths the need for early treatment with HF disease-modifying therapy and anticoagulation

Design of a multicentre randomized controlled trial to assess the safety and efficacy of dose titration by specialized nurses in patients with heart failure. ETIFIC study protocol.

Heart failure (HF) is associated with many hospital admissions and relatively high mortality, rates decreasing with administration of beta-blockers (BBs), angiotensin-converting-enzyme inhibitors, angiotensin II receptor blockers, and mineralocorticoid receptor antagonists. The effect is dose dependent, suboptimal doses being common in clinical practice. The 2012 European guidelines recommend close monitoring and dose titration by HF nurses. Our main aim is to compare BB doses achieved by patients after 4 months in intervention (HF nurse-managed) and control (cardiologist-managed) groups. Secondary aims include comparing doses of the other aforementioned drugs achieved after 4 months, adverse events, and outcomes at 6 months in the two groups. Methods We have designed a multicentre (20 hospitals) non-inferiority randomized controlled trial, including patients with new-onset HF, left ventricular ejection fraction ≤40%, and New York Heart Association class II-III, with no contraindications to BBs. We will also conduct qualitative analysis to explore potential barriers to and facilitators of dose titration by HF nurses. In the intervention group, HF nurses will implement titration as prescribed by cardiologists, following a protocol. In controls, cardiologists will both prescribe and titrate doses. The study variables are doses of each of the drugs after 4 months relative to the target dose (%), New York Heart Association class, left ventricular ejection fraction, N-terminal pro B-type natriuretic peptide levels, 6 min walk distance, comorbidities, renal function, readmissions, mortality, quality of life, and psychosocial characteristics. Conclusions The trial seeks to assess whether titration by HF nurses of drugs recommended in practice guidelines is safe and not inferior to direct management by cardiologists. The results could have an impact on clinical practice

Post-transplant lymphomas: a 20-year epidemiologic, clinical and pathologic study in a single center

Background and objectives: to study the incidence, clinical presentation, pathologic features and outcome of post-transplant lymphomas (PTL) during the past 20 years. Design and methods: we undertook a descriptive study of all biopsy-proven cases of PTL diagnosed in our hospital from 1979 through 1999. The average annual incidence rate of PTL was analyzed at 5-year intervals from 1979 to 1999. Risk ratios were estimated by comparing the incidence of PTL among transplanted patients with that of lymphoma observed in the general population of the region. Survival analysis was performed at the univariate level using the Kaplan Meier technique and at the multivariate level by Cox hazard models. Results: seventeen of 1,860 transplanted patients developed a PTL (0.9%). The risk of PTL was calculated to be almost 8-fold higher than the risk of lymphoma in the general population. The risk was highest among those who had received a heart transplant (RR=35.6). The mean time between transplant and the diagnosis of PTL was 31 +/- 29 months. Of all PTL, 88% were of B-cell origin and 53% of the cases tested were Epstein-Barr virus (EBV)-positive. The median survival was 24 months. The majority of patients with allograft involvement died within the 2 months following diagnosis (hazard ratio 5.3; 95% CI 1.4-20.7). Interpretation and conclusions: organ transplantation is a major risk factor for the development of lymphoma, a disease with a particularly bad prognosis when it develops at the site of the allograft. Early diagnosis and more specific treatment may improve PTL survival

Clinical Determinants and Prognosis of Left Ventricular Reverse Remodelling in Non-Ischemic Dilated Cardiomyopathy

Aims: Non-ischaemic dilated cardiomyopathy (NIDCM) is characterized by left ventricular (LV) chamber enlargement and systolic dysfunction in the absence of coronary artery disease. Left ventricular reverse remodelling (LVRR) is the ability of a dilated ventricle to restore its normal size, shape and function. We sought to determine the frequency, clinical predictors and prognostic implications of LVRR, in a cohort of heart failure (HF) patients with NIDCM. Methods: We conducted a multicentre observational, retrospective cohort study of patients with NIDCM, with prospective serial echocardiography evaluations. LVRR was defined as an increase of >= 15% in left ventricular ejection fraction (LVEF) or as a LVEF increase >= 10% plus reduction of LV end-systolic diameter index >= 20%. We used multivariable logistic regression analyses to identify the baseline clinical predictors of LVRR and evaluate the prognostic impact of LVRR. Results: LVRR was achieved in 42.5% of 527 patients with NIDCM during the first year of follow-up (median LVEF 49%, median change +22%), Alcoholic aetiology, HF duration, baseline LVEF and the absence of LBBB (plus NT-proBNP levels when in the model), were the strongest predictors of LVRR. During a median follow-up of 47 months, 134 patients died (25.4%) and 7 patients (1.3%) received a heart transplant. Patients with LVRR presented better outcomes, regardless of other clinical conditions. Conclusions: In patients with NIDCM, LVRR was frequent and was associated with improved prognosis. Major clinical predictors of LVRR were alcoholic cardiomyopathy, absence of LBBB, shorter HF duration, and lower baseline LVEF and NT-proBNP levels. Our study advocates for clinical phenotyping of non-ischaemic dilated cardiomyopathy and intense gold-standard treatment optimization of patients according to current guidelines and recommendations in specialized HF units
