Pharmacotherapy follow-up of patients under treatment with biologic agents for chronic inflammatory systemic conditions: an agreement among hospital pharmacists for the standardized collection of a minimum set of data / Seguimiento farmacoterapéutico en pacientes en tratamiento con agentes biológicos por enfermedades sistémicas inflamatorias crónicas: acuerdo entre farmacéuticos hospitalarios para la recopilación estandarizada de un conjunto mínimo de datos

Background and objective: The objective of this study was to reach a consensus on the minimum set of data that would allow to optimize the pharmacotherapy follow-up of patients on biologic agents for chronic systemic inflammatory conditions, through structured and standardized collection with an electronic tool in the hospital pharmacy. Materials and method: A scientific committee was formed (n = 5 hospital pharmacists). The Delphi Technique was used, 2 rounds of consultation by e-mail for hospital pharmacists. A structured questionnaire was used, based on a bibliographic review and recommendations by the scientific committee; 37 statements were assessed with the Likert 5-point scale (1= ‘Strongly Disagree’; 5= ‘Strongly Agree’). Consensus was reached when 75% or more of panel members assigned a score of 1-2 (rejection consensus) or 4-5 (agreement consensus) to the matter reviewed. Descriptive statistical analyses were conducted. Results: The study included 21 hospital pharmacists (70 were invited, there was 70% response). Consensus was reached for 100% of statements. The minimum set of data was agreed upon, as well as the recommendations that the pharmacist had to collect and make during visits: to document the health status, health-related quality of life, changes in treatment compliance and in patient autonomy, as well as the conditions to make feasible the systematic collection of the minimum data set. Conclusions: There is consensus among hospital pharmacists about a minimum data set to be collected, through an electronic tool, which will order, standardize and structure the pharmacotherapy follow-up of patients with chronic inflammatory conditions on treatment with biologic agents in the spanish public health system (AU)

The use of adalimumab, etanercept, golimumab and infliximab in rheumatic pathologies: variation between label dosage and real-world use.

Rheumatoid arthritis (AR), psoriatic arthritis (PSA) and ankylosing spondylitis (AS) are autoimmune systemic diseases characterized by inflammation, pain and joint degeneration. The objective of this study is to evaluate, under the actual conditions of use, dosing patterns of adalimumab, etanercept, golimumab and infliximab in these pathologies, and compare them with the label regimens recommended, as well as evaluating the financial implications of these regimen modifications. The study population included all adult patients diagnosed with RA, PSA or AS who had been treated with adalimumab, etanercept, golimumab and infliximab for at least 6 months between 1 January 2011 and 31 December 2013. The main variable of this study was to assess the dose dispensed for drugs administered subcutaneously and the dose prepared/administered for drugs administered intravenously, and the annual costs of the treatment. A total of 5,428 episodes were included. The mean weekly dose was lower than the standard dose in the three pathologies studied in the patients treated with adalimumab and etanercept (84.3% vs 81.2% for RA, 85.0% vs 78.0% for PSA and 87.8% vs 81.6% for AS). The drugs with highest dose optimization in RA are etanercept (46.3%) followed by adalimumab (46%); however, the highest percentage of patients with major dose optimization corresponds to etanercept (11.6%). Both in the PA and the AS group, we also observed that etanercept is the drug more optimized, corresponding to 53.9 and 43% of patients, respectively. By contrast, 48.5% of patients with RA treated with infliximab required dose intensification; however, infliximab dose intensification in PSA and AS is not so pronounced. The practice of optimization of dose regimens in patients with rheumatic diseases under treatment with anti-TNFα is spreading among professionals, resulting in annual cost reduction in the treatment of rheumatic arthropathies. However, long term follow-up will be necessary to assess the influence of this optimization on health outcomes.

Intravenous and subcutaneous immunoglobulin replacement: a two-way road. Optimizing healthcare quality in patients with primary immunodeficiencies.

PURPOSE: To evaluate the alternate use of subcutaneous immunoglobulin (SCIG) and intravenous immunoglobulin (IVIG) in patients with primary immunodeficiencies (PID) in a third-level Pediatric University Hospital. METHODS: Retrospective study of all patients receiving SCIG from 2006 to 2012. Data collected included demographics, date SCIG was started, date of switch to IVIG and reasons, administration tolerance, and related adverse events. Effectiveness was defined as the lack of severe infections. RESULTS: Twenty-three patients (15 male, 8 female) with PID were studied. SCIG was initiated at a median age of 14.2 years (8.4 months-25.7 years) and median duration on SCIG treatment was 41 months (4-68). Nine patients (39.1%) temporarily switched from SCIG to IVIG for the following reasons: vacation (8), administration issues (1), and transient need for immunomodulatory therapy (1). A mean of 5.2 IVIG infusions/patient (SD=2.86) was administered while on SCIG. IVIG-related adverse events were documented in 3 patients with 6 infusions. Eight (34.8%) patients definitively discontinued SCIG use for the following reasons: convenience (5), adverse effects (1), coagulopathy (1), and autoimmune thrombocytopenia (1). There were no severe infections requiring hospital admission in any patient during the study period. CONCLUSIONS: Alternating SCIG and IVIG use in patients with PID was associated with considerable advantages in terms of convenience for the patients and their caregivers, while maintaining the effectiveness and safety of this therapy. Healthcare units treating these patients should show flexibility with this dual therapy in order to optimize patients' quality of life.

Impact of parenteral nutrition standardization on costs and quality in adult patients.

BACKGROUND: Parenteral nutrition (PN) is a costly therapy that can also be associated with serious complications. Therefore, efforts are focusing on reducing rate of complications, and costs related to PN. OBJECTIVE: The aim was to analyze the effect of the implementation of PN standardization on costs and quality criteria. Secondary aim was to assess the use of individualized PN based on patient's clinical condition. METHODS: We compare the use of PN before and after the implementation of PN standardization. Demographic, clinical and PN characteristics were collected. Costs analysis was performed to study the costs associated to the two different periods. Quality criteria included were: 1) PN administration; 2) nutrition assessment (energy intake between 20-35 kcal/kg/day; protein contribution according to nitrogen balance); 3) safety and complications (hyperglycemia, hypertriglyceridemia, hepatic complications, catheter-related infection); 4) global efficacy (as serum albumin increase). Chi-square test was used to compare percentages; logistic regression analysis was performed to evaluate the use of customized PN. RESULTS: 296 patients were included with a total of 3,167 PN compounded. During the first period standardized PN use was 47.5% vs 85.7% within the second period (p < 0.05). No differences were found in the quality criteria tested. Use of individualized PN was related to critical care patients, hypertriglyceridemia, renal damage, and long-term PN. Mean costs of the PN decreased a 19.5%. Annual costs savings would be € 86,700. CONCLUSIONS: The use of customized or standard PN has shown to be efficient and flexible to specific demands; however customized PN was significantly more expensive.

Introducción: La nutrición parenteral (NP) es una terapia costosa asociada a serias complicaciones. De manera que muchos de los esfuerzos se centran en reducir éstas complicaciones, así como los costes asociados. Objetivos: Analizar el efecto de la estandarización de la NP en los costes y en indicadores de calidad. El objetivo secundario es estudiar la utilización de NP individualizadas en función de las condiciones clínicas de los pacientes. Métodos: Se compara la utilización de NP antes y después de la estandarización de la NP. Se recogen los datos demográficos, clínicos y características de la NP. Se realiza un análisis de costes asociados a los dos periodos de estudio. Se incluyen los siguientes indicadores de calidad: 1) Administración de NP; 2) Valoración nutricional (aporte calórico 20-35 kcal/kg/día; aporte proteico en función del balance nitrogenado); 3) seguridad y complicaciones (hiperglicemia, hipertrigliceridemia, complicaciones hepáticas, infección de catéter); eficacia global (aumento albúmina sérica). Se utiliza test de chi-cuadrado para comparación de porcentajes, y regresión logística para evaluar la utilización de NP individualizada. Resultados: Se incluyeron 296 pacientes para un total de 3,167 NP. Durante el primer período el uso de NP estandarizada fue del 47,5% frente 85,7% en el segundo (p < 0,05). No se encontraron diferencias en los indicadores de calidad estudiados. La utilización de NP individualizada fue relacionada con pacientes críticos, hipertrigliceridemia y NP de larga duración. El coste medio de NP disminuyó en un 19,5%; pudiendo resultar un ahorro anual de 86,700 . Conclusiones: La utilización de NP individualizadas o estándar ha mostrado ser eficiente y flexible; aunque el coste de la individualizada fue significativamente mayor.

Cost analysis of adult parenteral nutrition systems; three-compartment bag versus customized / Análisis de costes de los sistemas de nutrición parental; bolsa tricompartimental versus individualizada

BACKGROUND: Parenteral nutrition (PN) is a costly technology used widely to provide nutrition to patients who have an inaccessible or non-functioning intestine. Two all-in-one systems currently being used are customized formulations and three-compartment bags. OBJECTIVE: To provide a systematic cost comparison of the two all-in-one PN systems: individualized (made from nutrient solutions) versus commercialized (made from three-compartment bag), both prepared in hospital pharmacies. SETTING: This study was conducted in three public Spanish hospitals. METHOD: We conducted a cost-minimization study to analyze prospectively the total cost of PN bags, accounting for all of the processes involved in preparing and delivering PN bags (cost of manpower, nutrition solutions, medical supplies and quality controls) in three different healthcare settings. To compare therapeutic alternatives of equivalent nutritional value, the study was performed for the most frequently employed formulation and similar to commercial preparations. A univariate sensitivity analysis was performed to evaluate the impact of different rates of use of three-compartment PN bag. RESULTS: 157 routine acts of PN bag preparation (65 customized and 92 three-compartment) were observed and timed over 9 days. Total costs of the 157 PN bags were included in the study. Mean costs of customized bags were higher than three-compartment bags, 51.16 ± 5.63 € versus 39.69 ± 3.00 € respectively (p < 0.01). Manpower costs were responsible for the majority of the differences found (70%). The time to complete an adult bag for the hospital compounded system was a mean of 25.9 minutes longer than the three-compartment system. In scenarios using a three-compartment system for 30%, 70% and 90% of PN provision, a cost savings of 4.3%, 10.1% and 12.9% respectively could be achieved. Greatest rates of changing from customized bags (70% and 90%), in a hospital with 1,800 PN bags/year, might reduce the annual budget by 9306 € and 11,964.8 €, respectively. Meanwhile, in a large facility the savings for 8,000 TPN days would be 64,248 € and 82,605 €, respectively. CONCLUSIONS: Since seeking cost-reduction of effective treatments is needed, the use of three-compartment bags for standard adult PN could lead to cost savings. Our data should be helpful for health care providers to calculate their own cost of administer

ANTECEDENTES: La nutrición parenteral (NP) es una tecnología costosa que se usa ampliamente para proporcionar nutrición a los pacientes que tienen un intestino inaccesible o no funcional. Los dos sistemas todo en uno que se utilizan en la actualidad son las formulaciones individualizadas y las bolsas tri-compartimentales. OBJETIVO: Proporcionar una comparación de costes sistemática entre los dos sistemas todo en uno: los sistemas individualizados (preparados a partir de soluciones de nutrientes) frente a los comerciales (hechos a partir de una bolsa tri-compartimental). Contexto: Este estudio se realizó en tres hospitales públicos españoles. MÉTODO: Realizamos un estudio de minimización de costes para analizar prospectivamente el coste total de las bolsas de NP, considerando todos los procesos implicados en la preparación y suministro de las bolsas (coste de personal, soluciones de nutrición, material fungible y controles de calidad) en tres centros hospitalarios distintos. Para comparar alternativas terapéuticas de valor nutricional equivalente, el estudio se realizó con la formulación que se empleaba con mayor frecuencia y similar a los preparados comerciales. Se realizó un análisis de sensibilidad uni-variaante para evaluar el impacto de las diferentes tasas de uso de la bolsa de NP tri-compartimental. RESULTADOS: Se analizaron 157 elaboraciones de bolsas de NP (65 individualizada y 92 tri-compartimentales) programadas durante 9 días. Los costes totales de las 157 bolsas de NP se incluyeron en el estudio. Los costes medios de las bolsas individualizadas fueron superiores a los costes de las bolsas tri-compartimentales, 51,16 ± 5,63 € frente a 39,69 ± 3,00 €, respectivamente (p < 0,01). Los costes de personal fueron los responsables de la mayor parte de las diferencias encontradas (70%). El tiempo para completar una bolsa de formulación individualizada fue en promedio 25,9 minutos superior que para el sistema tri-compartimental. En los supuestos en que se utilizase el sistema tri-compartimental un 30%, 70% y 90% del total de NP, se producirían unos ahorros del 4,3%, 10,1% y 12,9%, respectivamente. Con mayores tasas de cambio (70% y 90%), en un hospital con 1.800 bolsas de NP/año, se podría obtener un ahorro en el presupuesto anual de 9.306 € y 11.964.8 €, respectivamente. A su vez, en un centro hospitalario mayor, el ahorro para 8.000 bolsas de NP sería de 64.248 € y 82.605 €, respectivamente. CONCLUSIONES: Dada la necesidad de buscar una reducción de costes de tratamientos efectivos, el uso de las bolsas tri-compartimentales para la NP estándar del adulto podría conllevar una reducción de costes. Nuestros datos pueden ayudar a los gestores sanitarios a calcular su propio coste de administración de la NPT
