Relevance of Dementia in Atrial Fibrillation Patients within a Specific European Health Care Area.

INTRODUCTION: Atrial fibrillation might increase the risk of dementia. We aim to test the hypothesis that dementia could reclassify the actual risk of stroke and death predicted by the CHA2DS2-VASc in patients with atrial fibrillation (AF). METHODS: A prospective study performed in a specific health care area. RESULTS: From our health care area (n = 348,985), throughout 2013, AF was codified in 7,990 (2.08%). Mean age was 76.83 ± 10.5, mean CHA2DS2-VASc = 3.5, 4,056 (50.8%) were females and 287 (3.6%) were diagnosed to have dementia. Patients with dementia were older and presented a higher rate of all the components of the CHA2DS2-VASc-expect vasculopathy. Differences in overall mortality were observed but not in stroke and haemorrhagic events. After propensity score matched analysis, dementia was independently associated with all-cause mortality. Addition of dementia to CHA2DS2-VASc reclassified 7.7 and 16.6% of the cohort with regard to thromboembolic events and death risk respectively. CONCLUSIONS: Patients with dementia presented a more adverse risk profile, with significant differences in all-cause mortality.

Analysis of the quality of e-Consultations in chronic obstructive pulmonary disease.

INTRODUCTION: The quality of e-Consultations in the COPD is unknown. The objectives of this study were (i) to evaluate the quality of referrals; (ii) to define the characteristics of patients referred from Primary Care (PC) to the Unit of Pulmonology; and (iii) to describe differences between accepted and rejected patients. METHODS: A retrospective, observational study of e-Consultations requested by PC for suspected COPD throughout 2022. To quantify the quality of the e-Consultations, an arbitrary scale of 12 variables (score 0-10) was created. RESULTS: In total, 384 e-Consultations were reviewed, of which 167 (43.5 %) resulted in a face-to-face visit, and 217 (56.5 %) were rejected. No differences were observed between the two types of patients, except for confirmations of diagnostic suspicion of COPD [significantly higher in accepted patients (p = 0.042)]; physical examination data of rejected patients (more data provided; p = 0.015); and lung function (significantly better in rejected patients). The mean quality of referrals was acceptable (5.6 ± 2.1 score): 121 (31.3 %) had insufficient quality; 118 (30.5 %) acceptable; 75 (19.4 %) good, and 30 (7.8 %) excellent. Quality was low in half of the variables analyzed (6/12); acceptable in 3, and good in another 3. The capacity of resolution of referrals was good (one e-Consultation) in 199 requests (66.1 %); deficient (two e-Consultations) in 72 (23.9 %), and poor (≥3 e-Consultations) in 30 (10 %). Overdiagnosis was 40.2 % (86/214 e-Consultations). The risk could be classified in 247 patients (64.3 %; 135 low-risk; 90 high-risk). CONCLUSIONS: When adequate information is provided, e-Consultations help identify different levels of severity. However, the quality and capacity of resolution of referrals were suboptimal, with a high percentage of overdiagnoses.

Cost-Effectiveness of a New Outpatient Pulmonology Care Model Based on Physician-to-Physician Electronic Consultation.

Introduction: This study assesses the impact of an electronic physician-to-physician consultation program on the waiting list and the costs of a Pulmonology Unit. Materials and Methods: A prepost intervention study was conducted after a new ambulatory pulmonary care protocol was implemented and the capacity of the unit was adopted. In the new model, physicians at all levels of healthcare send electronic consultations to specialists. Results: In the preintervention year (2019), the Unit of Pulmonology attended 7,055 consultations (466 e-consultations and 6,589 first face-to-face visits), which decreased to 6,157 (3,934 e-consultations and 2,223 first face-to-face visits; 12.7% reduction) in the postintervention year (all were e-consultations). The mean wait time for the first appointment was 25.7 days in 2019 versus 3.2 days in 2021 (p < 0.001). In total, 43.5% of cases were solved via physician-to-physiciane-consultation. A total of 2,223 patients needed a face-to-face visit, with a mean wait time of 7.5 days. The mean of patients in the waiting listing decreased from 450.8 in 2019 to 44.8 in 2021 (90% reduction). The annual time devoted to e-consultations and first face-to-face visits following an e-consultation diminished significantly after the intervention (1,724 hours versus 2,312.8; 25.4% reduction). Each query solved via e-consultation represented a saving of €652.8, resulting in a total annual saving of €827,062. Conclusions: Physician-to-physiciane-consultations reduce waiting times, improve access of complex patients to specialty care, and ensure that cases are managed at the appropriate level. E-consultation reduces costs, which benefits both, society and the healthcare system.

A prospective study of the clinical outcomes and prognosis associated with comorbid COPD in the atrial fibrillation population.

BACKGROUND: Patients with COPD are at higher risk of presenting with atrial fibrillation (AF). Information about clinical outcomes and optimal medical treatment of AF in the setting of COPD remains missing. We aimed to describe the prevalence of COPD in a sizeable cohort of real-world AF patients belonging to the same healthcare area and to examine the relationship between comorbid COPD and AF prognosis. METHODS: Prospective analysis performed in a specific healthcare area. Data were obtained from several sources within the "data warehouse of the Galician Healthcare Service" using multiple analytical tools. Statistical analyses were completed using SPSS 19 and STATA 14.0. RESULTS: A total of 7,990 (2.08%) patients with AF were registered throughout 2013 in our healthcare area (n=348,985). Mean age was 76.83±10.51 years and 937 (11.7%) presented with COPD. COPD patients had a higher mean CHA2DS2-VASc (4.21 vs 3.46; P=0.02) and received less beta-blocker and more digoxin therapy than those without COPD. During a mean follow-up of 707±103 days, 1,361 patients (17%) died. All-cause mortality was close to two fold higher in the COPD group (28.3% vs 15.5%; P<0.001). Independent predictive factors for all-cause mortality were age, heart failure, diabetes, previous thromboembolic event, dementia, COPD, and oral anticoagulation (OA). There were nonsignificant differences in thromboembolic events (1.7% vs 1.5%; P=0.7), but the rate of hemorrhagic events was significantly higher in the COPD group (3.3% vs 1.9%; P=0.004). Age, valvular AF, OA, and COPD were independent predictive factors for hemorrhagic events. In COPD patients, age, heart failure, vasculopathy, lack of OA, and lack of beta-blocker use were independent predictive factors for all-cause mortality. CONCLUSION: AF patients with COPD have a higher incidence of adverse events with significantly increased rates of all-cause mortality and hemorrhagic events than AF patients without COPD. However, comorbid COPD was not associated with differences in cardiovascular death or stroke rate. OA and beta-blocker treatment presented a risk reduction in mortality while digoxin use exerted a neutral effect.

Clinical profile and outcomes in octogenarians with atrial fibrillation: A community-based study in a specific European health care area.

BACKGROUND: Age increases risk of stroke and bleeding. Clinical trial data have had relatively low proportions of elderly subjects. We sought to study a Spanish population of octogenarians with atrial fibrillation (AF) by combining different sources of electronic clinical records from an area where all medical centres utilized electronic health record systems. METHODS: Data was derived from the Galician Healthcare Service information system. RESULTS: From 383,000 subjects, AF was coded in 7990 (2.08%), 3640 (45.6%) of whom were ≥80 and 4350 (54.4%)<80. All CHA2DS2-VASc's components were more prevalent in the elderly except for diabetes. Of those ≥80, 2178 (59.8%) were women. Mean CHA2DS2-VASc was 4.2±1.1. Distribution of CHA2DS2-VASc components varied between genders. 2600 (71.4%) were on oral anticoagulant (OA). During a median follow up of 696days (124.23), all-cause mortality was higher in ≥80 (1011/3640 (27.8%) vs 350/4350 (8.05%) (p<0.001). There were differences in rate of thromboembolic (TE) and haemorrhagic events (2.3% vs 0.9%, p<0.01 and 2.5% vs 1.7%, p=0.01 respectively). In octogenarian, differences between genders were observed with regard to TE, but not in haemorrhagic or all-cause mortality rates. Age, heart failure, non-valvular AF, dementia, and OA were independent predictors of all-cause mortality. In regard to TE, female gender, hypertension, previous TE and OA were independent predictive factors. CONCLUSIONS: Octogenarians with AF had very different characteristics and outcomes from their younger counterparts. These results also provide reassurance about the effectiveness of OA in preventing TE events and maintaining a reasonable haemorrhagic event rate in the extremely elderly.
