ABSTRACT
BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is the most severe long-term complication of acute pulmonary embolism (PE). We aimed to evaluate the impact of a symptom screening programme to detect CTEPH in PE survivors. METHODS: This was a multicentre cohort study of patients diagnosed with acute symptomatic PE between January 2017 and December 2018 in 16 centres in Spain. Patients were contacted by phone 2 years after the index PE diagnosis. Those with dyspnoea corresponding to a New York Heart Association (NYHA)/WHO scale≥II, visited the outpatient clinic for echocardiography and further diagnostic tests including right heart catheterisation (RHC). The primary outcome was the new diagnosis of CTEPH confirmed by RHC. RESULTS: Out of 1077 patients with acute PE, 646 were included in the symptom screening. At 2 years, 21.8% (n=141) reported dyspnoea NYHA/WHO scale≥II. Before symptom screening protocol, five patients were diagnosed with CTEPH following routine care. In patients with NYHA/WHO scale≥II, after symptom screening protocol, the echocardiographic probability of pulmonary hypertension (PH) was low, intermediate and high in 76.6% (n=95), 21.8% (n=27) and 1.6% (n=2), respectively. After performing additional diagnostic test in the latter 2 groups, 12 additional CTEPH cases were confirmed. CONCLUSIONS: The implementation of this simple strategy based on symptom evaluation by phone diagnosed more than doubled the number of CTEPH cases. Dedicated follow-up algorithms for PE survivors help diagnosing CTEPH earlier. TRIAL REGISTRATION NUMBER: NCT03953560.

OBJECTIVES: To describe the management of superficial vein thrombosis (SVT) of the lower limbs in patients treated in Spanish hospital emergency departments (EDs). To evaluate the impact of ED management of venous thromboembolic complications on outcomes and to determine the characteristics of patients who develop complications. MATERIAL AND METHODS: The retrospective multicenter ALTAMIRA study (Spanish acronym for risk factors, complications, and assessment of Spanish ED management of SVT) used recorded data for consecutive patients with a diagnosis of isolated SVT treated in 18 EDs. We gathered data on symptomatic venous thromboembolic disease (deep vein thrombosis, pulmonary embolism, or the extension or recurrence of SVT), clinically significant bleeding, and 180-day mortality. Cox regression analysis was used to explore variables associated with complications. RESULTS: A total of 703 patients were included. Anticoagulation was prescribed for 84.1% of the patients for a median of 30 days (interquartile range, 15-42 days); 81.3% were treated with low molecular weight heparin. A prophylactic dose was prescribed for 48% and an intermediate therapeutic dose for 52%. Sixty-four patients (9.2%) developed symptomatic thromboembolic disease within 180 days, 12 (1.7%) experienced clinically significant bleeding, and 4 (0.6%) died. Complications developed later in patients receiving anticoagulant therapy than in those not taking an anticoagulant (66 vs 11 days , P=.009), and 76.6% of those developing complications were not on anticoagulant when symptoms appeared. A history of thromboembolic disease was associated with developing complications (adjusted hazard ratio, 2.20; 95% confidence interval, 1.34-3.62). CONCLUSION: ED treatment of SVT varies and is often suboptimal. The incidence of thromboembolic complications after SVT is high. Starting anticoagulation in the ED delays the development of complications. Patients with a history of thromboembolic disease are more at risk of complications.
OBJETIVO: Describir el manejo terapéutico de los pacientes con trombosis venosa superficial (TVS) aislada de miembros inferiores en servicios de urgencias hospitalarios (SUH) españoles. Evaluar el impacto del tratamiento instaurado en urgencias en la evolución, en términos de complicaciones de enfermedad tromboembólica venosa (ETV), y conocer las características de los pacientes que sufren complicaciones. METODO: El estudio multicentrico (18 SUH) ALTAMIRA (fActores de riesgo, compLicaciones y evaluación del manejo de la TVS de Miembros Inferiores en hospitales españoles atendidos en los seRvicios de urgenciAs) creó un cohorte retrospectivo de pacientes consecutivos con diagnóstico objetivo de TVS aislada. Se recogieron las complicaciones de ETV sintomáticas (trombosis venosa profunda, tromboembolia pulmonar y extensión o recurrencia de TVS), sangrados clínicamente relevantes y defunciones a 180 días. Se evaluaron las variables asociadas a las complicaciones mediante una regresión de Cox. RESULTADOS: Se incluyeron 703 pacientes. El 84,1% recibieron anticoagulación durante 30 días (rango intercuartil 15-42), 81,3% con heparina de bajo peso molecular (48% dosis profilácticas, 52% intermedias-terapéuticas). En 180 días, 64 pacientes (9,1%) tuvieron complicación de ETV, 12 (1,7%) tuvieron sangrado clínicamente relevante, y 4 fallecieron (0,6%). Los pacientes en que se instauró anticoagulación en urgencias tardaron más tiempo en desarrollar complicaciones (66 vs 11 días, p = 0,009). El 76,6% de los que se complicaron no estaban anticoagulados en ese momento. La ETV previa se asoció de forma independiente con el desarrollo de complicaciones (hazard ratio ajustada 2,20; intervalo de confianza del 95%: 1,34-3,62). CONCLUSIONES: El tratamiento en urgencias de la TVS aislada es heterogéneo y con frecuencia subóptimo. La incidencia de complicaciones de ETV es elevada. El tratamiento anticoagulante iniciado en urgencias supone un retraso en el desarrollo de complicaciones. Los pacientes con ETV previa tienen más riesgo de complicaciones.

OBJECTIVES: To describe the characteristics of patients with isolated lower-limb superficial vein thrombosis (SVT) treated in hospital emergency departments and to evaluate adherence to clinical practice guidelines on diagnosis (vein ultrasound imaging) and therapeutic management (start of anticoagulant therapy). MATERIAL AND METHODS: Retrospective cohort study in 18 Spanish emergency departments. We included all patients with a final emergency department diagnosis of lower-limb SVT aged 18 years or older between January 2016 and May 2017. Backward stepwise multiple logistic regression analysis was used to evaluate adherence to clinical practice guidelines on ordering vein ultrasound imaging and starting anticoagulant therapy. RESULTS: A total of 1166 patients were included. The mean patient age was 59.6 years, and 67.9% were women. About a quarter of the patients (24.4%) had a history of venous thromboembolic disease. Complications developed in 8.9% within 180 days: 4.6% experienced a recurrence and 3.6% progressed to SVT and 1.8% to deep vein thrombosis; pulmonary thromboembolism occurred in 0.9%. Hemorrhagic complications developed in 17 patients (1.5%). Sixteen patients (1.4%) died. Vein ultrasound imagine was ordered for 703 patients (60.3%). Anticoagulant agents were prescribed for 898 (77%) for a median period of 22 days. Variables associated with a decision to order anticoagulants were a history of venous thromboembolic disease (odds ratio [OR], 1.60; 95% CI, 1.12-2.30), varicose veins (OR, 1.40; 95% CI, 1.12-2.30); limb pain (OR, 1.44; 95% CI, 1.08-1.91); painful cord (OR, 1.30; 95% CI, 0.97-1.73); and availability of vein ultrasound images (OR, 1.60; 95% CI, 1.94-3.45). CONCLUSION: Adherence to clinical practice guidelines for the diagnosis and treatment of isolated lower-limb SVT is low in Spanish emergency departments. Ultrasound imaging is not ordered for 1 out of every 2 to 3 patients, and anticoagulant treatment is not started in 1 out of 4 patients. There is great room for improvement.

METODO: . Estudio de cohortes retrospectivo en 18 SUH españoles. Se incluyeron todos los pacientes atendidos en los SUH con diagnóstico final de TVS en miembros inferiores, con edad $ 18 años, de enero de 2016 a mayo de 2017. Para evaluar la no adherencia a las recomendaciones de las guías de práctica clínica (realización de ecografía venosa, e instauración de tratamiento anticoagulante) se ajustó un modelo de regresión logística múltiple por pasos hacia atrás. RESULTADOS: . Mil ciento sesenta y seis pacientes fueron incluidos. La edad media fue de 59,6 años, el 67,9% eran mujeres. El 24,4% tenían antecedentes de enfermedad tromboembólica venosa (ETV). El 8,9% tuvieron alguna complicación a 180 días [4,6% recurrencia y 3,6% progresión de TVS, 1,8% trombosis venosa profunda (TVP) y 0,9% tromboembolia pulmonar (TEP)]. Hubo 17 pacientes (1,5%) con hemorragia y 16 (1,4%) muertes. Se realizó ecografía venosa a 703 (60,3%) pacientes. Recibieron tratamiento anticoagulante 898 (77%), con una mediana de 22 días. Las variables asociadas con la decisión de anticoagular fueron: antecedentes ETV (OR 1,60; IC 95%: 1,12-2,30), varices (OR 1,40; IC 95%: 1,12-2,30), dolor de la extremidad (OR 1,44; IC 95%: 1,08-191), presencia de cordón doloroso (OR 1,30; IC 95%: 0,97-1,73) y realización de ecografía venosa (OR 1,60; IC 95%: 1,94-3,45). CONCLUSIONES: Existe una baja adherencia a las recomendaciones de las guías de práctica clínica en el manejo diagnóstico y terapéutico de los pacientes con diagnóstico de TVS aislada de miembros inferiores en los SUH españoles: no se realiza ecografía venosa en uno de cada 2-3 pacientes, y no se instaura tratamiento anticoagulante en 1 de cada 4. Esto constituye un margen de mejora muy relevante.
