Analysis of the implementation of an innovative IT solution to improve waiting times, communication with primary care and efficiency in Rheumatology.

OBJECTIVE: To describe in detail an innovative program based on telemedicine for semi-automated prioritization of referrals from Primary Care (PC) to Rheumatology, for reproducibility purposes, and to present the results of the implementation study. METHODS: The context and situation were carefully analyzed, paying attention to all processes in place, referral numbers, waiting times, and number of complementary tests prior to discharge from Rheumatology. The composition of the team, aims, users, scope, and implementation phases were defined. Eight process indicators were established and measured before and 32 months after the program implementation. RESULTS: The program, which includes IT circuits, algorithms based on response to specific guideline-based checklists, e-consultation, and appointments based on priority, was fully implemented in our health area after a pilot study in two PC centers. After implementation, 6185 rheumatology referrals showed an e-consultation response delay of 8.95 days, and to first face-to-face visit (after e-consultation) of 12.6 (previous delay before program implementation was 83.1 days). Resolution by e-consultation reached 20% (1195 patients did not need seeing the rheumatologist to have the problem solved), and 1369 patients (32%) were discharged after the first visit. The overall resolution rate was 44.0% (2564 discharges/5830 e-consultations). From a random sample of 100 visits, only 10% of patients needed additional complementary tests to make a diagnosis and decision by Rheumatology (20.9% decrease from previous period). CONCLUSION: A careful analysis of the situation and processes, with implementation of simple IT circuits, allows for the improvement of the efficiency and resolution of problems in Rheumatology.

Impacto de la anticoagulación en los pacientes con demencia y fibrilación auricular. Resultados del registro CardioCHUVI-FA / Impact of anticoagulation in patients with dementia and atrial fibrillation. Results of the CardioCHUVI-FA registry

INTRODUCCIÓN Y OBJETIVOS: El envejecimiento de la población se asocia con una prevalencia creciente de fibrilación auricular (FA) y demencia. Con este estudio se pretende analizar el impacto de la anticoagulación oral en pacientes ancianos con FA y demencia de grado moderado-grave. MÉTODOS: Estudio retrospectivo unicéntrico que analiza a pacientes de edad ≥ 85 años con diagnóstico de FA entre 2013 y 2018. El impacto de la anticoagulación en la mortalidad, las embolias y las hemorragias se evaluó mediante un análisis multivariado de Cox. En los pacientes con demencia, dicho análisis se complementó con un propensity score matching en función de que se les prescribiera tratamiento anticoagulante o no. RESULTADOS: De los 3.549 pacientes de 85 o más años con FA, 221 presentaban demencia de grado moderado-grave (6,1%), de los que 88 (60,2%) fueron anticoagulados. Durante un seguimiento de 2,8 ±1,7 años, la anticoagulación se asoció con menor riesgo embólico y mayor riesgo hemorrágico tanto en pacientes con demencia (HRembolias=0,36; IC95%, 0,15-0,84; HRhemorragias=2,44; IC95%, 1,04-5,71) como sin demencia (HRembolias=0,58; IC95%, 0,45-0,74; HRhemorragias=1,55; IC95%, 1,21-1,98). Sin embargo, la anticoagulación únicamente se asoció con menor mortalidad en los pacientes sin demencia (HR=0,63; IC95%, 0,53-0,75), no en pacientes con demencia (HR ajustada=1,04; IC95%, 0,63-1,72; p = 0,541; HR después de propensity score matching=0,91; IC95%, 0,45-1,83; p = 0,785). CONCLUSIONES: En pacientes de 85 o más años con demencia moderada-grave y FA, la anticoagulación oral se asoció de manera significativa con menor riesgo de embolias y mayor riesgo hemorrágico, sin encontrarse diferencias en cuanto a mortalidad total

INTRODUCTION AND OBJECTIVES: Population aging is associated with an increased prevalence of atrial fibrillation (AF) and dementia. This study aimed to analyze the impact of oral anticoagulation in elderly patients with AF and moderate-severe dementia. METHODS: We conducted a single-center retrospective study analyzing patients aged ≥ 85 years with a diagnosis of AF between 2013 and 2018. The impact of anticoagulation on mortality, embolisms, and bleeding events was assessed by multivariate Cox analysis. In patients with dementia, this analysis was complemented by propensity score matching, depending on whether the patients were prescribed anticoagulant treatment or not. RESULTS: Of the 3549 patients aged ≥ 85 years with AF, 221 had moderate-severe dementia (6.1%), of whom 88 (60.2%) were anticoagulated. During a follow-up of 2.8 ±1.7 years, anticoagulation was associated with lower embolic risk and higher bleeding risk both in patients with dementia (hazard ratio [HR]embolisms, 0.36; 95%CI, 0,15-0.84; HRbleeding, 2.44; 95%CI, 1.04-5.71) and in those without dementia (HRembolisms, 5.58; 95%CI, 0.45-0.74; HRbleeding, 1.55, 95%CI, 1.21-1.98). However, anticoagulation was associated with lower mortality only in patients without dementia (HR, 0.63; 95%CI, 0.53-0.75) and not in those with dementia (adjusted HR, 1.04; 95%CI, 0.63-1.72; P=.541; HR after propensity score matching 0.91, 95%CI, 0.45-1.83; P=.785). CONCLUSIONS: In patients aged ≥ 85 years with moderate-severe dementia and AF, oral anticoagulation was significantly associated with a lower embolic risk and a higher bleeding risk, with no differences in total mortality

Impact of malnutrition in the embolic-haemorrhagic trade-off of elderly patients with atrial fibrillation.

AIMS: Nutrition is an important determinant of health above the age of 80 years. Malnutrition in the elderly is often underdiagnosed. The aim of this study was to report the prevalence and prognostic value of malnutrition in patients ≥80 years old with atrial fibrillation (AF) with and without anticoagulant therapy. METHODS AND RESULTS: We assessed the nutritional status of 4724 octogenarian patients with diagnoses of AF in a single centre from Spain between 2014 and 2017 with the CONUT score. Malnutrition was confirmed in 2036 patients (43.1%). Anticoagulation prescription was more frequent in patients with good nutrition than in those malnourished (79.5% vs. 71.7%, P < 0.001). The impact of malnutrition on mortality was evaluated by Cox regression, whereas its association with ischaemic stroke and major bleeding was studied through competing risk analysis. After multivariate adjusting, malnutrition was associated with mortality [hazard ratio (HR) 1.36, 95% confidence interval (CI) 1.24-1.49], stroke [sub-distribution HR (sHR) 1.37, 95% CI 1.10-1.69], and major bleeding (sHR 1.29, 95% CI 1.02-1.64). In anticoagulated patients, the embolic-haemorrhagic trade-off event was virtually neutral for those who had normal nutritional status [average daily rates (ADRs) for stroke and bleeding: 4.70 and 4.69 per 100 000 patients/day, respectively; difference = +0.01 per 100 000 patients/day; P = 0.99] and negative for those with malnutrition (ADR for stroke and bleeding: 5.38 and 7.61 per 100 000 patients/day, respectively; difference = -2.23 per 100 000 patients/day; P = 0.07). CONCLUSION: Malnutrition is very common in octogenarian patients with AF, being a clinical predictor for poor prognosis. For anticoagulated patients, malnutrition was associated with a negative embolic-haemorrhagic balance.

Vitamin K Antagonists and Direct Oral Anticoagulants in Nonagenarian Patients With Atrial Fibrillation.

OBJECTIVES: Nonagenarian patients are underrepresented in clinical trials that have evaluated oral anticoagulation in patients with atrial fibrillation (AF). The aim of this study was to assess the pronostic impact of oral anticoagulation in patients with AF age ≥90 years. DESIGN: Retrospective multicenter study of nonagenarian patients with AF. SETTING AND PARTICIPANTS: A total of 1750 nonagenarian inpatients and outpatients with nonvalvular AF between January 2013 and December 2018 in 3 Spanish health areas were studied. METHODS: Patients were divided into 3 groups based on antithrombotic therapy: nonoral anticoagulants (30.5%), vitamin-K antagonists (VKAs; 28.6%), and direct oral anticoagulants (DOACs; 40.9%). During a mean follow-up of 23.6 ± 6.6 months, efficacy outcomes (death and embolic events) were evaluated using a Cox regression analysis and safety outcomes (bleeding requiring hospitalization) by competing-risk regression. Results were complemented with a propensity score matching analysis. RESULTS: During follow-up, 988 patients died (56.5%), 180 had embolic events (10.3%), and 186 had major bleeding (10.6%). After multivariable adjustment, DOACs were associated with a lower risk of death and embolic events than nonanticoagulation [hazard ratio (HR) 0.75, 95% confidence interval (CI)] 0.61‒0.92), but VKAs were not (HR 0.87, 95% CI 0.72‒1.05). These results were confirmed after propensity score matching analysis. For bleeding, both DOACs and VKAs proved to be associated with a higher risk (HR for DOAC 1.43; 95% CI 0.97‒2.13; HR for VKA 1.94; 95% CI 1.31‒2.88), although findings for DOACs were not statistically significant (P = .074). For intracranial hemorrhage (ICH), only VKAs-not DOACs-presented a higher risk of ICH (HR 4.43; 95% CI 1.48‒13.31). CONCLUSIONS AND IMPLICATIONS: In nonagenarian patients with AF, DOACs led to a reduction in mortality and embolic events in comparison with nonanticoagulation. This reduction was not observed with VKAs. Although both DOACs and VKAs increased the risk of bleeding, only VKAs were associated with higher ICH rates.
