Real-World Treatment Patterns, Resource Use and Costs in Adult Patients With Atopic Dermatitis Receiving Systemic Treatment: Derma-Atopic Study in Spain / Características de los pacientes, patrones de tratamiento, uso de recursos y costes en adultos con dermatitis atópica moderada-grave en la práctica habitual en España: Estudio Derma-Atopic

Background Moderate–severe atopic dermatitis (AD) has a significant impact on patients’ lives, with many requiring systemic treatment to manage symptoms (e.g., pruritus). Several drugs are used off-label to treat AD. This study describes sociodemographic/clinical characteristics, treatment patterns, health resource use (HRU) and costs in adults with AD who initiated systemic treatment or phototherapy in routine practice. Methods This retrospective observational study of electronic medical records in the BIG-PAC database identified adults with prior diagnosis of AD (ICD-9: 691.8 or 692.9) starting oral corticosteroids, immunosuppressants, biologics or phototherapy between 01/01/2012 and 31/12/2016. Patients were followed for 3 years from treatment initiation, up to 31/12/2019. Data on patient characteristics, treatment patterns, HRU and costs were analyzed descriptively. Results Patients (N = 1995) had a mean age of 60 years, 64% were female, with a mean time of 23 years since diagnosis (84% were ≥18 years at AD onset). Main comorbidities were anxiety (38%), arterial hypertension (36%) and dyslipidemia (35%). Most patients used oral corticosteroids as first systemic (84%; median duration 29 days) and immunosuppressants in 13% of patients (median duration 117 days, 5% cyclosporine and 4% methotrexate). Half of patients required a second line systemic and 12% a third line. The use of immunosuppressants and biologics increased with treatment lines. About 13% of patients received systemic treatments continuously over the 3-year follow-up. The average 3-year per patient cost was 3835 euros, with an average annual cost of 1278 euros. Conclusions Results suggest a high comorbidity and economic burden in this real-world adult population with AD, and the need for systemic treatments indicated for use in AD (AU)

Antecedentes La dermatitis atópica (DA) moderada-grave tiene un impacto significativo en la vida de los pacientes, muchos de los cuales requieren tratamiento sistémico para controlar los síntomas (p. ej., prurito). Algunos tratamientos son usados fuera de indicación. Este estudio describió características sociodemográficas y clínicas, patrones de tratamiento, uso de recursos sanitarios (URS) y costes asociados en adultos con DA que iniciaron tratamiento sistémico o fototerapia en la práctica habitual. Métodos Este estudio observacional retrospectivo de historias clínicas electrónicas en la base de datos BIG-PAC identificó adultos con diagnóstico previo de DA (CIE-9: 691.8 o 692.9) que comenzaron con corticosteroides orales, inmunosupresores, biológicos o fototerapia entre el 01/01/2012 y el 31/12/2016. Se siguió a los pacientes durante 3 años desde el inicio del tratamiento, hasta 31/12/2019. Los datos sobre las características clínicas de los pacientes, patrones de tratamiento, URS y costes se analizaron de forma descriptiva. Resultados Los pacientes (N = 1995) tenían una edad media de 60 años, el 64% eran mujeres, con una media de 23 años desde el diagnóstico (84% tenían ≥ 18 años al inicio de la DA). Las principales comorbilidades fueron ansiedad (38%), hipertensión arterial (36%) y dislipidemia (35%). La mayoría de los pacientes utilizaron corticosteroides orales como primer tratamiento sistémico (84%; duración media 29 días) e inmunosupresores en el 13% de los pacientes (duración media 117 días, ciclosporina en el 5% y metotrexato en el 4%). La mitad de los pacientes requirieron una segunda línea de tratamiento sistémico y el 12% una tercera. El uso de inmunosupresores y biológicos aumentó simultáneamente con las líneas de tratamiento. Aproximadamente el 13% de los pacientes recibieron tratamientos sistémicos de forma continua durante los 3 años de seguimiento. El coste medio por paciente a 3 años fue de 3.835 euros, con un coste medio anual de 1.278 euros (AU)

Economic Consequences of the Overuse of Short-Acting ß-Adrenergic Agonists in the Treatment of Asthma in Spain.

BACKGROUND AND OBJECTIVE: To determine the relationship between short-acting ß-adrenergic agonist (SABA) overuse and health care resource use and costs in asthma patients in routine clinical practice. METHODS: A longitudinal retrospective study was conducted in Spanish primary and specialized care centers using the BIG-PAC medical records database. The study population comprised asthma patients ≥12 years of age who attended ≥2 consultations during 2017 and had 1-year follow-up data available. The main outcomes were demographics, comorbidities, medication, and clinical and health care resource use and costs. The relationship between SABA overuse and health care costs and between asthma severity and health care costs was determined. RESULTS: The SABA use IN Asthma (SABINA) study included 39 555 patients, with a mean (SD) age of 49.8 (20.7) years (64.2% female). The Charlson comorbidity index was 0.7 (1.0). SABA overuse (≥3 canisters/y) was 28.7% (95%CI, 27.7-29.7), with a mean of 3.3 (3.6) canisters/y. Overall, 5.1% of patients were prescribed ≥12 canisters/y. SABA overuse was correlated with health care costs (ρ=0.621; P<.001). The adjusted mean annual cost/patient according to the Global Initiative for Asthma (GINA 2019) classification of asthma severity was €2231, €2345, €2735, €3473, and €4243 for steps 1-5, respectively (P<.001). Regardless of asthma severity, SABA overuse yielded a significant increase in health care costs per patient and year (€5702 vs €1917, P<.001) compared with recommended use (<2 canisters/y). CONCLUSION: SABA overuse yields high costs for the Spanish National Health System. Costs increased with severity of asthma.

Objetivo: Determinar la relación entre la sobreutilización de agonistas beta adrenérgicos de acción corta (SABA) en pacientes con asma y el uso y coste de recursos sanitarios en la práctica clínica rutinaria. Métodos: Se realizó un estudio longitudinal retrospectivo en atención primaria y especializada en España, en el que se utilizó la base de datos de registros médicos BIG-PAC®. Se incluyeron pacientes con asma ≥12 años que asistieron a ≥2 consultas durante 2017 y con datos disponibles del seguimiento durante 1 año. Los principales resultados analizados fueron características demográficas, comorbilidades, medicaciones, y el uso y coste de recursos clínicos y sanitarios. Se determinó la relación de los costes sanitarios tanto con la sobreutilización de SABA como con la severidad del asma. Resultados: Este estudio sobre el uso de SABA en asma (SABINA, del inglés “SABA use IN Asthma”) incluyó a 39.555 pacientes, con una edad media (DE, desviación estándar) de 49,8 años (20,7); 64.2% fueron mujeres. La media del índice de comorbilidad Charlson fue 0,7 (1,0). La sobreutilización de SABA (≥3 envases/año) fue del 28,7% (IC95%: 27,7–29,7), con una media global de 3,3 envases (3,6) /año. En total, el 5,1% de los pacientes fueron prescritos con ≥12 envases/año. La sobreutilización de SABA correlacionó con los costes sanitarios (ρ = 0,621; p < 0,001). El coste medio anual/paciente según la clasificación de severidad del asma de la Global Initiative for Asthma (GINA 2019) fue de 2.231 €, 2.345 €, 2.735 €, 3.473 €, y 4.243 €, para los pasos 1-5, respectivamente (p < 0,001) (AU)

Prevalence, T2-biomarkers and cost of severe asthma in the era of biologics: The BRAVO-1 study.

BACKGROUND AND OBJECTIVES: The last decade has seen a new era of classifications of asthma pathophysiology which have changed the treatment options available. To update the figures of prevalence of T2 asthma, comorbidities, biomarker characterization and costs of severe asthma in patients≥12-years-old adapted to this new situation. METHODS: Retroprospective, observational, nationwide study using a top-down approach. Data were obtained from the BIG-PAC®, an electronic medical record database of 1.7 million patients in Spain. Patients≥12-years-old who had received medical care during the period 2016-2017 and diagnosed with asthma at least one year prior to the index date were included and followed for one year. RESULTS: Prevalence of asthma was 5.5%. Of these patients, asthma was severe in 3.031 (7.7%), 81.2% of whom presented T2 asthma. Among severe asthma patients, 64·1% were uncontrolled, 31.2% were Oral corticosteroids-dependent (37% in the uncontrolled severe asthma group) and only 3.8% were on biologics. The most common T2 comorbidities were allergic rhinitis (66·1%), atopic dermatitis (29·1%) and chronic rhinositis with nasal polyps (14.6%). Mortality rates in the total and the uncontrolled severe asthma groups were 4.2% and 5.5% respectively. The total annual costs per patient with severe asthma were 5.890€ (uncontrolled) and 2.841€ (controlled). CONCLUSIONS: In the era of biologics, most severe asthma patients present T2 asthma. Despite the availability of new treatments, the rates of uncontrolled and oral corticosteroids-dependent patients with severe asthma remain high, but biologics still underused. The costs of uncontrolled severe asthma are twice as high as those of controlled severe asthma.

Características clínicas, manejo y riesgo de complicaciones a un año en pacientes con insuficiencia cardíaca con y sin diabetes tipo 2 en España / Clinical characteristics, management, and one-year risk of complications among patients with heart failure with and without type 2 diabetes in Spain

Objetivos: Describir las características clínicas y el manejo terapéutico y determinar los eventos cardiovasculares tras un año de seguimiento en una población contemporánea con insuficiencia cardíaca (IC) con y sin diabetes tipo 2 en España. También se analizó en la población DAPA-HF (pacientes que cumplieron la mayoría de los criterios de inclusión del estudio DAPA-HF) y en los pacientes tratados basalmente con inhibidores SGLT2.Métodos: Estudio observacional, retrospectivo, poblacional, empleando la base de datos BIG-PAC. La fecha índice fue 1 de enero de 2019. Se seleccionaron sujetos≥18 años que recibieron tratamiento por IC en 2019. Se analizaron los eventos durante 2019.Resultados: Se identificaron 21.851 pacientes con IC (78±11,3 años; 53% varones; 50,9% IC con fracción de eyección reducida; 44,5% en clase funcional NYHA II). La prevalencia de IC fue del 1,88% y la incidencia 2,83 por 1.000 pacientes-año. El 66,1% tomaba inhibidores del sistema renina-angiotensina, el 69,4% betabloqueantes, el 31,2% antialdosterónicos y el 7,5% sacubitrilo/valsartán. Durante el año de seguimiento, el 29,8% fue hospitalizado por descompensación de la IC (tiempo medio primer evento 120,9±72,5 días), un 12,3% murieron, un 8,1% murieron durante la hospitalización. Los eventos fueron más frecuentes en los pacientes con diabetes tipo 2. Las hospitalizaciones por IC fueron más comunes en la población similar a DAPA-HF.Conclusiones: En España, la población con IC es anciana y tiene muchas comorbilidades. Aproximadamente la mitad de los pacientes tienen IC con fracción de eyección reducida. Existe margen de mejora en el manejo de la IC, en particular mediante el empleo de aquellos fármacos que reducen tanto la hospitalización por IC como la mortalidad, para disminuir la carga de IC (AU)

Objective: This work aims to describe the clinical characteristics and therapeutic management and to determine cardiovascular outcomes after one year of follow-up in a contemporaneous population with heart failure (HF) with and without type 2 diabetes in Spain. These factors were also analyzed in the DAPA-HF-like population (patients who met most inclusion criteria of the DAPA-HF trial) and in patients treated with SGLT2 inhibitors at baseline.Methods: This work is an observational, retrospective, population-based study using the BIG-PAC database. The index date was January 1, 2019. People aged≥18 years who received care for HF in 2019 were selected. Events that occurred in 2019 were analyzed.Results: We identified 21,851 patients with HF (age 78.0±11.3 years, 53.0% men, 50.9% with HF with reduced left ventricular ejection fraction, 44.5% in NYHA functional class II). HF prevalence was 1.88% and incidence was 2.83 per 1,000 person-years. Regarding HF treatments, 66.1% were taking renin-angiotensin system inhibitors, 69.4% beta blockers, 31.2% aldosterone antagonists, and 7.5% sacubitril/valsartan. During the year of follow-up, 29.8% had HF decompensation which led to hospitalization (mean time to first event of 120.9±72.5 days), 12.3% died, and 8.1% died during hospitalization. Events were more common among patients with type 2 diabetes. Hospitalizations for HF were more common in the DAPA-HF-like population.Conclusions: In Spain, the population with HF is elderly and has many comorbidities. Approximately half of patients have HF with reduced left ventricular ejection fraction. There is room for improvement in HF management, particularly through the use of drugs that reduce both HF hospitalization and mortality, in order to reduce the burden of HF (AU)

[Treatment persistence with brand-name vs. generic metformin in monotherapy for type 2 diabetes: real-life retrospective study using the propensity matching score]. / Persistencia al tratamiento con metformina de marca vs. genérica en monoterapia para la diabetes tipo 2: estudio retrospectivo de vida real mediante propensity score matching.

OBJECTIVE: To evaluate treatment persistence in patients with polymedicated type 2 diabetes (DM2) receiving new treatment with brand-name vs. generic metformin 850mg in usual clinical practice. PATIENTS AND METHODS: Observational, retrospective study based on the medical records of patients aged ≥50 years who initiated metformin treatment (brand-name vs. generic) between 01/01/2016 and 31/12/2017. The follow up was two years. MAIN MEASURES: treatment persistence and clinical consequences (metabolic control [HbA1c] and hospital admissions). Each patient in the brand-name group (reference) was paired with a patient from the generic group using propensity score matching. A Cox proportional risk model was constructed (p<0.05). RESULTS: 863 patients receiving brand-name metformin were matched (ratio 1:1) with patients receiving generic metformin. The median age was 60.8 years (SD: 8.8) years and 52.6% were female. Persistence at 24 months was 8.6% higher for brand-name vs. generic metformin (63.2% vs. 58.2%; p=0.034). The hazard ratio for brand-name metformin was 0.83 (95% CI: 0.71-0.96, p=0.013). During the follow-up there was a greater percentage reduction of HbA1c in the brand-name vs. generic group (-6.8% vs. -4.1%; p=0.013). There was a non-significant 19.1% reduction in hospital admissions in the brand-name vs. generic group (8.9% vs. 11.0%; p=0.148). CONCLUSIONS: Polymedicated patients who initiated new brand-name metformin treatment for DM2 had greater treatment persistence than those who initiated it with generic metformin and had better metabolic control (percentage reduction in HbA1c).

Consecuencias clínicas y económicas en pacientes que inician tratamiento con clopidogrel de marca vs. genérico: estudio retrospectivo de vida real / Clinical and economic consequences in patients initiating therapy with clopidogrel brand-name vs. generic: a real-life retrospective study

OBJETIVO: Evaluar la persistencia al tratamiento y el uso de los recursos y sus costes en sujetos que inician tratamiento con clopidogrel de marca frente a genérico para el síndrome coronario agudo (SCA) y la enfermedad arterial periférica (EAP). PACIENTES Y MÉTODOS: Estudio observacional-retrospectivo, realizado a partir de los registros médicos de pacientes ≥18 años, que iniciaron un nuevo tratamiento con clopidogrel (marca vs. genérico) entre el 1 de abril de 2015 y el 31 de marzo de 2017. Se compararon 4 grupos de estudio y el seguimiento fue de un año. Principales medidas: comorbilidad, persistencia al tratamiento, ratio posesión-medicación (RPM) y uso de recursos y costes. Los resultados se analizaron mediante análisis multivariante, p < 0,05. RESULTADOS: Se compararon 4 grupos: a) SCA: clopidogrel-marca (n=1.067) vs. genérico (n=3.504); y b) EAP: clopidogrel-marca (n=425) vs. genérico (n=994). Para el SCA (edad media: 69,7 años; 61,4% hombres), con clopidogrel de marca, la persistencia (65,3% vs. 61,0%; p < 0,001); hazard-ratio ajustado 0,85 y el RPM (89,8% vs. 86,7%; p = 0,045) fueron superiores al genérico. El promedio/unitario del coste fue menor (2.890€ vs. 3.865€, p = 0,001).Para la EAP se observaron resultados similares con clopidogrel de marca, la persistencia (64,7% vs. 58,9%; p = 0,039), hazard-ratio ajustado 0,86 y el RPM (88,6% vs. 81,7%; p = 0,013) fueron superiores al genérico. El promedio/unitario del coste fue menor (2.880€ vs. 3.532€, p = 0,044). CONCLUSIONES: Los pacientes que inician tratamiento con clopidogrel de marca vs. genérico, tanto para el SCA como para el EAP, se asociaron a un mayor grado de adherencia al tratamiento, repercutiendo en unos menores costes sanitarios para el Sistema Nacional de Salud

OBJECTIVE: To evaluate the adherence to treatment, resource use, and costs in subjects initiating treatment with brand-name versus generic clopidogrel for acute coronary syndrome (ACS) and peripheral arterial disease (PAD). PATIENTS AND METHODS: Observational, retrospective study based on the medical records of patients aged ≥18 years who initiated treatment with clopidogrel (brand-name vs. generic) between 4 April 2015 and 31 March 2017. Four study groups were compared, and the follow-up was one year. The main measurements were: comorbidity, treatment adherence, medication possession ratio (MPR), resource use, and costs. The results were analysed using multivariate analysis. The level of statistical significance was P<.05. RESULTS: Four groups were compared: a) ACS: brand-name clopidogrel (N=1,067) vs. generic (N=3,504), and b) PAD: brand-name clopidogrel (N=425) vs. generic (N=994). In the ACS comparison (mean age: 69.7 years, 61.4% male), adherence (65.3% vs. 61.0%, P<.001), adjusted hazard ratio 0.85 and MPR (89.8% vs. 86.7%, P=.045) were more superior with brand-name clopidogrel than with the generic and with a lower mean cost per unit (€2,890 vs. €3,865, P=.001). In the PAD comparison, similar results were observed: persistence (64.7% vs. 58.9%, P=.039); adjusted hazard-ratio 0.86 and MPR (88.6% vs. 81.7%; P=.013) were more superior with brand-name clopidogrel than for the generic, with a lower mean cost per unit (€2,880 vs. €3,532, P=.044). CONCLUSIONS: There was better treatment adherence in patients initiating treatment with brand-name compared with generic clopidogrel for ACS and PAD, resulting in lower health costs for the Spanish National Health System

[Clinical and economic consequences in patients initiating therapy with clopidogrel brand-name vs. generic: A real-life retrospective study]. / Consecuencias clínicas y económicas en pacientes que inician tratamiento con clopidogrel de marca vs. genérico: estudio retrospectivo de vida real.

OBJECTIVE: To evaluate the adherence to treatment, resource use, and costs in subjects initiating treatment with brand-name versus generic clopidogrel for acute coronary syndrome (ACS) and peripheral arterial disease (PAD). PATIENTS AND METHODS: Observational, retrospective study based on the medical records of patients aged ≥18 years who initiated treatment with clopidogrel (brand-name vs. generic) between 4 April 2015 and 31 March 2017. Four study groups were compared, and the follow-up was one year. The main measurements were: comorbidity, treatment adherence, medication possession ratio (MPR), resource use, and costs. The results were analysed using multivariate analysis. The level of statistical significance was P<.05. RESULTS: Four groups were compared: a) ACS: brand-name clopidogrel (N=1,067) vs. generic (N=3,504), and b) PAD: brand-name clopidogrel (N=425) vs. generic (N=994). In the ACS comparison (mean age: 69.7 years, 61.4% male), adherence (65.3% vs. 61.0%, P<.001), adjusted hazard ratio 0.85 and MPR (89.8% vs. 86.7%, P=.045) were more superior with brand-name clopidogrel than with the generic and with a lower mean cost per unit (€2,890 vs. €3,865, P=.001). In the PAD comparison, similar results were observed: persistence (64.7% vs. 58.9%, P=.039); adjusted hazard-ratio 0.86 and MPR (88.6% vs. 81.7%; P=.013) were more superior with brand-name clopidogrel than for the generic, with a lower mean cost per unit (€2,880 vs. €3,532, P=.044). CONCLUSIONS: There was better treatment adherence in patients initiating treatment with brand-name compared with generic clopidogrel for ACS and PAD, resulting in lower health costs for the Spanish National Health System.

Treatment persistence and adherence and their consequences on patient outcomes of generic versus brand-name statins routinely used to treat high cholesterol levels in Spain: a retrospective cost-consequences analysis.

BACKGROUND: High blood lipoprotein concentrations are one of the major risk factors for cardiovascular diseases. Drug therapy is the base of treatment; statins in particular. Both brand-name and generic presentations are available for statin therapy of high cholesterol levels. Factors that may influence their use in routine medical practice include, among others, patient persistence and adherence to treatment as prescribed by physicians. The aim of this retrospective analysis was to provide real-world evidence of treatment persistence and adherence and their consequences on economic and patient outcomes of generic versus brand-name statins routinely used to treat high cholesterol levels in Spain. METHODS: Existing real-world electronic medical records abstracted from a database of two regions in Spain were analyzed. The analysis compared generic versus brand-name statins data from subjects' who started treatment between July 1, 2010 and June 30, 2012. Treatment persistence, adherence expressed as medication possession ratio (MPR), healthcare resource utilization and their costs were analyzed together with patient's at-goal rates of low-density-lipoprotein-cholesterol (LDL-c), incidence of any major cardiovascular event (CVE) and all-cause mortality during a 5-year follow-up period. Multivariate analyses were applied. RESULTS: A total of 13,244 records were included. Persistence was lower with generics; adjusted hazard ratio -HR- [95% confidence interval]: 0.86 [0.82-0.91], p < 0.001) and MPR was also lower: 61.5% vs. 65.1% (p < 0.001). Less patients with generics reached their LDL-c goal: 39.2% [38.3-40.2%] vs. 42.0% [40.2-43.7%]; adjusted odds ratio; 0.87 [0.80-0.95], p = 0.003. Compared to brand-name statins, the observed probability of occurrence of a CVE; HR: 1.31 [1.15-1.50], p < 0.001, and also all-cause deaths; HR: 1.36 [1.15-1.62], was significantly higher with generics; p < 0.001 in both cases. Adjusted mean total healthcare cost per patient was also higher with generic than with brand-name statins: €9118 (9059-9176) vs. €7980 (7853-8808) [adjusted difference: €1137 (997-1277), p < 0.001]. CONCLUSION: This retrospective cost-consequences analysis found poorer treatment persistence and adherence in patients who first started therapy with generic instead of brand-name statins in routine medical practice in Spain. Also, patients receiving generics were more unlikely to reach LDL-c goals, showed increased probability of having CVE and all-cause mortality at a higher cost to payers.

Persistencia al tratamiento y uso de recursos con corticosteroides y agonistas ß-adrenérgicos de larga duración inhalados a dosis fijas para el tratamiento del asma: estudio retrospectivo de base poblacional / Persistence to treatment and resources use with inhaled fixed-dose combinations of corticosteroids and long-acting ß-adrenergic agonists for the treatment of asthma: A population-based retrospective study

Objetivo: Determinar la persistencia, las exacerbaciones y el uso de los recursos en los pacientes que inician tratamiento inhalador con fluticasona propionato/formoterol (PF/Form) con relación a otras combinaciones de corticoide inhalado/agonista ß-adrenérgico de larga duración (CI/LABA) en dosis fijas, para el tratamiento del asma en condiciones de práctica clínica habitual. Material y métodos: Estudio observacional realizado a partir de la revisión de registros médicos. Se incluyeron sujetos ≥18 años que iniciaron tratamiento con CI/LABA y que cumplieran con determinados criterios de inclusión/exclusión. El seguimiento se realizó durante un año. Grupos de estudio: a) PF/Form y b) otras-combinaciones (Otros-CI/LABA). Principales medidas: persistencia, ratio posesión del medicamento (RPM), exacerbaciones y costes (directos/indirectos). El análisis estadístico se elaboró mediante modelos de regresión, con p <0,05. Resultados: Se seleccionó a 3.203 pacientes. Por grupos: a) PF/Form: 7,0% y b) Otros-CI/LABA: 93,0%. La edad media fue de 52,2 años y el 60,8% fueron mujeres. El 44,9% de los pacientes presentaban un asma persistente-moderado. Los pacientes en tratamiento con PF/Form se asociaron a una mayor persistencia (67,6 vs. 61,2%; p=0,043), mayor RPM (80,6 vs. 74,3%; p=0,002) y menores exacerbaciones (16,0 vs. 21,9%; p=0,021), especialmente exacerbaciones severas (4,0 vs. 7,7%; p=0,043). El promedio/unitario del coste total (ANCOVA) fue menor en los pacientes en tratamiento con PF/Form (2.033 vs. 2.486 €; p=0,012), respectivamente. El coste total se asoció a exacerbaciones (ß = 0,618), severidad-asma (ß = 0,214), edad (ß = 0,073) y falta de adherencia (RPM: ß = −0,031), con p <0,01. Conclusiones: Los pacientes en tratamiento con PF/Form se asociaron a una mayor adherencia al tratamiento (persistencia, RPM), circunstancia que repercute en menores exacerbaciones severas y costes totales para el sistema nacional de salud. Estas diferencias podrían ser debidas a las propiedades farmacológicas del fármaco o a otros factores no medidos

Objective: To determine the persistence, exacerbations, and use of resources in patients who use inhaler treatment with fluticasone propionate/formoterol (PF/Form) in relation with other combinations of inhaled corticosteroid/long-acting ß-adrenergic (ICS/LABA) at fixed doses, for the treatment of asthma in real-life practice. Material and methods: Observational study conducted by reviewing medical records. The study included subjects ≥18 years of age who started treatment with ICS/LABA and who met certain inclusion/exclusion criteria. The follow-up was carried out for one year. Study groups: a) PF/Form and b) Other-combinations (Other-ICS/LABA). Main measurements: Persistence, medication possession ratio (MPR), exacerbations, and costs (direct/indirect). The statistical analysis was performed using regression models, with a P<.05. Results: A total of 3,203 patients were included in the study. By groups: a) FP/Form: 7.0% and b) Other-ICS/LABA: 93.0%. The mean age was 52.2 years, and 60.8% were women. A total of 44.9% of patients had persistent-moderate asthma. Patients under treatment with FP/Form were associated with greater persistence (67.6 vs. 61.2%, P=.043), a higher RPM (80.6 vs. 74.3%, P=.002), and less exacerbations (16.0 vs. 21.9%, P=.021), particularly severe-exacerbations (4.0 vs. 7.7%, P=.043). The mean/unit of the total cost (ANCOVA) was lower in patients under treatment with PF/Form (2,033 vs. € 2,486, P=.012), respectively. The total cost was associated with: Exacerbations (ß=0.618), asthma-severity (ß=0.214), age (ß=0.073), and lack-adherence (RPM: ß=−0.031), P<.01. Conclusions: Patients undergoing treatment with PF/Form were associated with greater adherence to treatment (persistence, RPM), a circumstance that leads to less severe exacerbations and total costs for the national health system. These differences could be due to the pharmacological properties of the drug or other factors not measured

Efecto de la edad y el género sobre las consecuencias clínicas y económicas del tratamiento con especialidad farmacéutica de marca o genérica en pacientes con dolor neuropático periférico en práctica clínica habitual / Clinical and economic consequences of treating patients with peripheral neuropathic pain with brand name or generic drugs in routine clinical practice: The effects of age and sex

OBJETIVO: Analizar el efecto de la edad y el género sobre el dolor y los costes en pacientes con dolor neuropático periférico (DNp) crónico que inician tratamiento con gabapentina (marca) frente a gabapentina genérica (EFG). MÉTODOS: Estudio multicéntrico-retrospectivo, realizado con registros médicos electrónicos (RME) de pacientes de ambos géneros, > 18años, que iniciaron nuevo tratamiento con gabapentina de marca o genérico. Durante un año se midió la adherencia (ratio posesión medicación [RPM]) y la persistencia, la utilización de recursos sanitarios, los costes y la reducción del dolor. RESULTADOS: Se analizaron 1.369 RME (61,1% mujeres; edad 64,6 [15,9] años, 52,4% ≥ 65 años); marca: 400, EFG: 969. La persistencia y la adherencia fueron mayores con marca: 7,3 vs. 6,3 meses (p < 0,001) y 86,5 vs. 81,3% de RPM (p < 0,001). Con marca, se observaron costes sanitarios menores, tanto en < 65 como en ≥ 65años (diferencias medias por paciente de 221 Euros [IC95%: 59-382] y de 217 Euros [51-382], respectivamente [p < 0,01]), como en hombres (diferencias medias de 197 Euros [63-328]) o mujeres (diferencias de 239 Euros [96-397]), p = 0,005 y p = 0,004, respectivamente. Comparado con EFG, el tratamiento con marca mostró una reducción mayor del dolor: 13,5% (10,9-16,2) y 10,8% (8,2-13,5) en < 65 y ≥ 65 años, respectivamente (p < 0,001), así como del 10,7% (8,2-13,2) y del 13,8% (11,0-16,5) en mujeres y hombres, respectivamente (p < 0,001). CONCLUSIONES: Con independencia del género o la edad, los pacientes que iniciaron tratamiento del DNp con gabapentina de marca vs. genérico mostraron un mayor grado de adherencia y persistencia al tratamiento, repercutiendo en unos menores costes sanitarios, a la vez que se observaron mayores reducciones del dolor

OBJECTIVE: We aimed to analyse the effects of age and sex on pain and cost for patients with chronic peripheral neuropathic pain (PNP) who have started treatment with brand name gabapentin versus generic gabapentin (EFG). METHODS: We conducted a retrospective multicentre study using electronic medical records (EMR) for patients of both sexes, older than 18, who began treatment with brand name or generic gabapentin. Adherence (medication possession ratio [MPR]), persistence, use of healthcare resources, cost, and pain reduction were measured for one year. RESULTS: We analysed 1369 EMRs [61.1% women; mean age 64.6 (15.9), 52.4% ≥ 65 years]; 400 used brand name drugs while 969 used generic gabapentin. Persistence and adherence were higher in patients using brand name gabapentin (7.3 vs 6.3 months, P < .001; 86.5% vs 81.3% MPR, P < .001). Lower healthcare costs were observed in patients using brand-name gabapentin in both age groups (< 65 and ≥ 65). Mean difference in cost per patient amounted to Euros221 (95%CI: 59-382) and Euros 217 (95%CI: 51-382) in the < 65 and ≥ 65 age groups, respectively (P < .01). Mean difference in cost among men amounted to Euros 197 (63-328), while mean difference in cost among women amounted to Euros 239 (96-397) (P = .005 and P = .004, respectively). Compared with EFG, brand treatment showed greater pain relief: 13.5% (10.9-16.2) and 10.8% (8.2-13.5) in < 65 and ≥ 65year patients, respectively (P < .001), and 10.7% (8.2-13.2) and 13.8% (11.0-16.5) in women and men respectively (P < .001). CONCLUSIONS: Regardless of sex and age, patients who started PNP treatment with brand name medication showed greater persistence and adherence to treatment than those taking generic drugs. Brand name treatment also involved lower healthcare costs, and greater pain relief

CONCLUSIONS: Patients undergoing treatment with PF/Form were associated with greater adherence to treatment (persistence, RPM), a circumstance that leads to less severe exacerbations and total costs for the national health system. These differences could be due to the pharmacological properties of the drug or other factors not measured.

Uso de recursos y costes asociados a la no adherencia al tratamiento con corticoides inhalados en el asma / Use of resources and costs associated with non-adherence to inhaled corticosteroid treatment in asthma

Objetivo. Estimar la tasa de adherencia al tratamiento antiasmático con corticoide inhalado en condiciones de práctica clínica habitual, así como su relación con las exacerbaciones, el uso de recursos y los costes. Material y métodos. Estudio observacional retrospectivo realizado en el ámbito de Badalona Serveis Assistencials. Se incluyeron pacientes≥15 años con diagnóstico confirmado de asma que iniciaron tratamiento con corticoide inhalado entre enero 2010-diciembre 2011. El periodo de seguimiento fue de 24 meses. La adherencia al tratamiento se midió con la tasa de posesión de medicación, estableciéndose 2 grupos: pacientes adherentes (ADH; tasa de posesión de medicación≥80%) y no adherentes (no-ADH; tasa de posesión de medicación<80%). Se recogieron las variables demográficas y clínicas, las exacerbaciones, el uso de recursos sanitarios y no sanitarios (días de baja laboral) y los costes. Resultados. Se incluyeron 2.303 pacientes, con una edad media de 48,6 años, un 64,3% fueron mujeres y un 52,6% presentaban asma persistente moderada. Un 51,0% eran ADH al tratamiento. De los pacientes no-ADH, un 63,4% presentó exacerbaciones durante el periodo de estudio frente al 37,4% de los pacientes ADH (p<0,001), presentando, además, un mayor consumo de recursos sanitarios, especialmente visitas a Atención Primaria (22,5 vs. 17,4%), especializada (3,3 vs. 2,5%) y urgencias (1,4% vs. 0,2%) (p<0,001 en todos los casos). No se encontraron diferencias estadísticamente significativas en los días de baja laboral. El coste total anual fue de 1.431€/paciente no-ADH frente a 722€/paciente ADH (p<0,001). Conclusión. La falta de adherencia se relacionó con un aumento de la tasa de exacerbaciones, así como del consumo de recursos sanitarios y costes (AU)

Objective. To estimate adherence to asthma treatment with inhaled corticosteroid in clinical daily practice, and its relationship with exacerbations, as well as its use of resources and costs. Material and methods. An observational, retrospective study using the electronic medical records of the Badalona Health Service provider. The study included patients≥15 years old with a confirmed diagnosed of asthma, and who initiated treatment with an inhaled corticosteroid between January 2010 and December 2011. The follow-up period was 24 months. Adherence to treatment was measured using the medication possession ratio. Two groups were established: adherent (ADH; medication possession ratio≥80%) and non-adherent (non-ADH; medication possession ratio<80%) patients. The main demographic and clinical variables, including exacerbations, were collected, along with the healthcare and non-healthcare (days of absence from work) resource use, and costs. Results. The study included a total of 2,303 patients, with a mean age of 48.6 years, and 64.3% females. Just over half (52.6%) of the patients had moderate persistent asthma, and 51.0% of patients adhered to treatment. In the non-ADH patients, 63.4% suffered at least one exacerbation in the follow-up period, compared with 37.4% of the adherent patients (P<.001). The non-ADH patients also consumed a higher percentage of healthcare resources in Primary Care (22.5 vs. 17.4%), secondary care (3.3 vs. 2.5%), and emergency visits (1.4 vs. 0.2%) during the follow-up period (P<.001 in all cases). No statistical significance differences were observed in the days of absence from work. Mean annual cost of non-ADH patients was 1,431€/patient, compared with 722€/patient (P<.001) of ADH patients. Conclusion. Lack of adherence was associated with an increase in exacerbation rates, as well as healthcare resource consumption and costs (AU)

Impacto económico de la dermatitis atópica en adultos: estudio de base poblacional (estudio IDEA) / Economic Impact of Atopic Dermatitis in Adults: A Population-Based Study (IDEA Study)

OBJETIVO: Determinar el uso de los recursos y los costes de la dermatitis atópica (DA) en adultos según su gravedad y las comorbilidades asociadas en situación de práctica clínica habitual. PACIENTES Y MÉTODOS: Se efectuó un diseño observacional retrospectivo realizado a partir de la revisión de registros de pacientes ≥ 18 años que demandaron asistencia durante 2013-2014 en un área geográfica de Cataluña con una población de 215.634 personas. Se constituyeron 3 grupos de gravedad en función del tratamiento prescrito. Las variables evaluadas fueron el conjunto de comorbilidades, la medicación concomitante/específica; y los costes sanitarios directos/indirectos. El análisis estadístico se elaboró mediante modelos de regresión múltiple, p < 0,05. RESULTADOS: Se reclutaron 6.186 sujetos con diagnóstico de DA (edad-media: 47,1 años; mujeres, 61,6%). En función de la gravedad de la DA se consideraron 3 grupos; el 55,7% leve (n = 3.445), el 38,2% moderada (n = 2.361) y el 6,1% grave (n = 380). La DA grave se asoció a la probabilidad de presentar comorbilidades (Beta = 0,192); específicamente: asma (Beta = 0,138), depresión (Beta =0,099), eventos cardiovasculares (Beta = 0,087), obesidad (Beta = 0,085) y hábito tabáquico (Beta = 0,025), p < 0,001. El coste ascendió a 9,3 millones de euros (costes sanitarios: 75,5%; pérdidas de productividad: 24,5%), con un promedio/unitario de 1.504 euros/año. Los promedios/unitarios corregidos (ANCOVA) fueron mayores en la DA grave en comparación con la moderada y la leve (3.397 vs. 2.111 y 885 euros, respectivamente; p < 0,001). CONCLUSIONES: La DA grave se asocia a una elevada utilización de recursos sanitarios y costes para el Sistema Nacional de Salud proporcional a la gravedad de la dermatosis. La comorbilidad general y el asma fueron los factores con mayor impacto asociado al coste sanitario

OBJECTIVE: To determine resource usage and costs associated with atopic dermatitis in adults according to severity and comorbid conditions in daily clinical practice. PATIENTS AND METHODS: We performed an observational, retrospective study based on a review of registries of patients aged ≥ 18 years who sought health care in 2013 and 2014 in an area of Catalonia, Spain, with a population of 215,634 persons. We established 3 classes of severity depending on the treatment prescribed. The variables evaluated were total comorbid conditions, concomitant/specific medication, and direct/indirect health care costs. The statistical analysis was based on multiple regression models. Statistical significance was set at P < .05. RESULTS: We included 6,186 patients with a diagnosis of atopic dermatitis (mean age, 47.1 years; women, 61.6%). We established 3 groups based on severity, as follows: mild (n = 3,445 [55.7%]); moderate (n = 2,361 [38.2%]); and severe (n = 380 [6.1%]). Severe atopic dermatitis was associated with risk of presenting comorbid conditions (Beta = 0.192), namely, asthma (Beta = 0.138), depression (Beta = 0.099), cardiovascular events (Beta = 0.087), obesity (Beta = 0.085), and smoking (Beta = 0.025); P < .001. Costs reached Euros 9.3 million (health care costs, 75.5%; loss of productivity, 24.5%), with an average unit cost of Euros 1,504 per year. The corrected average unit cost (ANCOVA) was greater in severe atopic dermatitis compared with moderate and mild disease (Euros 3,397 vs. Euros 2,111 vs. Euros 885; P < .001), respectively. CONCLUSIONS: Severe atopic dermatitis generates considerable usage of health care resources and high costs for the National Health System. These are in proportion with the severity of the disease. General comorbid conditions and asthma were the factors with the greatest impact on health care costs
