Lista de comprobación para la atención farmacéutica del paciente con enfermedad pulmonar intersticial (CheckEPID): un consenso basado en el método Delphi / Checklist for Pharmaceutical Care of the Patient with interstitial lung disease (CheckEPID): A Delphi-based consensus

Objetivo desarrollar una lista de comprobación para facilitar la atención farmacéutica al paciente con enfermedad pulmonar intersticial que requieren o están en tratamiento con antifibróticos. Método 5 especialistas en farmacia hospitalaria desarrollaron un listado inicial de 37 ítems divididos en 4 bloques: 1) primera visita del paciente, que incluía datos generales del paciente y datos del primer tratamiento; 2) visitas de seguimiento, valorando aspectos del seguimiento del tratamiento con nintedanib o pirfenidona; 3) telefarmacia, consistente en la evaluación de la inclusión de pacientes en un programa de este tipo, evolución de la enfermedad e identificación del contacto con el servicio de farmacia y 4) tratamiento no farmacológico e información al paciente. Para decidir su potencial inclusión en el listado de comprobación se realizaron 2 rondas del Delphi en las que los panelistas tenían que valorar de cada ítem propuesto su grado de acuerdo con su «utilidad», que fue el criterio determinante para su inclusión y su «aplicabilidad». Resultados se contactó con 48 farmacéuticos hospitalarios, 30 (63%) aceptaron por escrito participar, 28 (58%) completaron la primera ronda del Delphi y 27 (56%) completaron la segunda ronda. Después de la primera ronda el cuestionario se modificó y quedó constituido por 40 ítems. De los 40 ítems evaluados tras las 2 rondas del Delphi, hubo 2 que, basados en la utilidad, los participantes del Delphi no alcanzaron el consenso para su inclusión en el listado: el referido a «Antecedentes de intervención quirúrgica, específicamente cirugía abdominal en las últimas 4 semanas» (finalmente mantenido en el listado por su implicación en la indicación de nintedanib) y el de realizar recomendaciones sobre «Relajación». En 2 de los ítems no se alcanzó consenso sobre su aplicabilidad: «Estratificación del paciente según el modelo del paciente crónico de la SEFH» y «Recogida de resultados comunicados por el paciente».

[Translated article] Checklist for the pharmaceutical care of patients with interstitial lung disease (CheckEPID): A Delphi-based consensus.

OBJECTIVE: To develop a checklist to facilitate pharmaceutical care for patients with interstitial lung disease who require or are undergoing treatment with antifibrotic drugs. METHOD: Five hospital pharmacists developed an initial list of 37 items divided into 4 blocks: (1) First visit, which included general patient data and data from the first treatment; (2) follow-up visits, assessing aspects of the follow-up of the treatment with nintedanib or pirfenidone; (3) telepharmacy, consisting of the evaluation of the inclusion of patients in a program of this type, course of the disease, and identification of the contact with the pharmacy service; (4) non-pharmacological treatment and patient information. To decide its potential inclusion in the checklist, 2 rounds of the Delphi were carried out in which the panelists had to assess the degree of agreement of each proposed item according to its "utility", which was the determining criterion for its inclusion, and its "applicability". RESULTS: Forty-eight hospital pharmacists were contacted, 30 (63%) agreed in writing to participate, 28 (58%) completed the first round of the Delphi, and 27 (56%) completed the second round. After the first round of the Delphi, the questionnaire was amended and comprised 40 items. Of the 40 items evaluated after the 2 rounds of the Delphi, there were 2 that, based on utility, the participants did not reach consensus for inclusion in the checklist: the one referring to "History of surgical intervention, specifically abdominal surgery in the last 4 weeks" (finally kept on the checklist due to its involvement in the indication of nintedanib) and to make recommendations on "Relaxation". No consensus was reached on their applicability for 2 of the items: "Patient stratification according to the Spanish Society of Hospital Pharmacy (SEFH) chronic patient model" and "Collection of Results Reported by the Patient". CONCLUSIONS: The management of patients with ILD and/or pulmonary fibrosis is complex and requires a multidisciplinary approach where the hospital pharmacist plays a key role, especially, although not only, in monitoring drug treatment. We believe that this checklist can contribute from pharmaceutical care to improving the integrated care of patients with ILD who require or are undergoing treatment with antifibrotic drugs.

Beneficio clínico y económico de 32 años de tratamiento antirretroviral de personas que viven con VIH en España: ¿ha sido una intervención eficiente? / Clinical and economic benefit of 32 years of antiretroviral treatment for people living with HIV in Spain: Has it been an efficient intervention?

Introducción: Aunque el tratamiento antirretroviral (TAR) del VIH/sida se introdujo en 1987, la mejora en la progresión de la enfermedad y reducción de la mortalidad poblacional no se observó sino hasta 1996, con la combinación de tres o más fármacos. El objetivo fue estimar el beneficio clínico y económico del TAR en España en el periodo de 32 años, comprendido entre 1987 y 2018. Métodos: Se realizó un análisis de coste-beneficio mediante la simulación de Monte Carlo de segundo orden, desde las perspectivas de la sociedad (caso base) y el Sistema Nacional de Salud (SNS). Los nuevos casos de VIH, sida y muertes relacionadas se obtuvieron de los registros SINIVIH y ONUSIDA, con proyecciones poblacionales sin TAR mediante suavizamiento exponencial triple. El gasto en TAR se obtuvo de informes del Plan Nacional del SIDA y estudios de mercado. Resultados: El SNS invirtió 6.185 millones de euros en 32 años. Durante este periodo se evitaron 323.651 muertes por sida, 500.129 casos de sida y 161.417 casos de VIH, con un ahorro total de 41.997 millones de euros. El beneficio neto (ahorros netos) se estima en 35.812 millones de euros (sociedad) y 1.032 millones de euros (SNS). Por cada euro invertido en TAR, se obtuvo un retorno de la inversión de 6,79 € y 1,16 €, respectivamente. Conclusión: La utilización de TAR durante 32 años ha evitado gran número de muertes y casos de sida y VIH, generando significativos ahorros económicos para el SNS. El TAR es una intervención eficiente para el SNS.(AU)

Introduction: Although antiretroviral therapy (ART) for HIV / AIDS was introduced in 1987, improvement in disease progression and reduction in mortality at a population level was not observed until 1996, with the combination of three or more drugs. The objective was to estimate the clinical and economic benefit of ART in Spain in the 32-year period between 1987 and 2018. Methods: A cost-benefit analysis was performed, using a second-order Monte Carlo simulation, from the societal (base case) and the National Health System (NHS) perspectives. New cases of HIV, AIDS and related deaths were obtained from the SINIVIH and UNAIDS registries, with population projections without ART using triple exponential smoothing. Expenditure on ART was obtained from the National AIDS Plan reports and market studies. Results: The NHS invested 6,185 million euros in 32 years. In that period, 323,651 AIDS-related deaths, 500,129 AIDS cases and 161,417 HIV cases were averted, with total savings of 41,997 million euros. The net benefit (net savings) is estimated at 35,812 million euros (societal) and 1,032 million euros (NHS). For every euro invested in ART, a return on investment of € 6.79 and € 1.16 was obtained, respectively. Conclusion: The use of ART over 32 years prevented a large number of deaths and cases of AIDS and HIV, providing significant economic savings for the NHS. ART is an efficient intervention for the NHS.(AU)

Thermolabile drug storage in an ambulatory setting.

More thermolabile drugs are becoming available, and in most cases, these medications are dispensed to ambulatory patients. However, there is no regulation once medications are dispensed to patients and little is known with regard to what happens during transport and home storage. Previous studies suggest that these drugs are improperly stored. The present study was designed to determine the storage conditions of thermolabile drugs once they are dispensed to the patient in the Hospital Pharmacy Department. This is a prospective observational study to assess the temperature profile of 7 thermolabile drugs once they are dispensed to ambulatory patients at a tertiary care hospital. A data logger was added to the medication packaging. Temperature was considered inappropriate if one of the following circumstances were met: any temperature record less than or equal to 0 °C or over 25 °C; temperatures between 0-2 or 8-25 °C for a continuous period over 30 min. The time series of temperature measurements obtained from each data logger were analyzed as statistically independent variables. The data shown did not undergo any statistical treatment and must be considered directly related to thermal measurements. One hundred and fourteen patients were included and 107 patients were available for the analysis. On the whole, a mean of 50.6 days (SD 18.3) were measured and the mean temperature was 6.88 °C (SD 2.93). Three data loggers (2.8%) maintained all the measurements between 2 and 8 °C with less than 3 continuous data (< 30 min) out of this range but no data over 25 °C or below or equal to 0 °C. 28 (26.2%) data loggers had at least one measurement below zero, 1 data logger had a measurement greater than 25 °C and 75 (70.1%) were between 0 and 2 °C and/or between 8 and 25 °C for more than 30 min. In conclusion, once dispensed to patients, most thermolabile drugs are improperly stored. Future studies should focus on clinical consequences and possible solutions.

Drug dosage recommendations in patients with chronic liver disease.

Chronic liver diseases (CLD) alter the kinetics of drugs. Despite dosage adjustment is based on Child-Pugh scores, there are no available recommendations and/or algorithms of reference to facilitate dosage regimens. A literature review about dose adjustment of the drugs from the hospital guide -which are included in the list of the WHO recommended drugs to be avoided or used with caution in patients with liver disease- was carried out. The therapeutic novelties from the last few years were also included. In order to do so, the summary of product characteristics (SPC), the database DrugDex-Micromedex, the WHO recommendations and the review articles from the last 10 years in Medline were reviewed. Moreover, the kinetic parameters of each drug were calculated with the aim of establishing a theoretical recommendation based on the proposal of Delcò and Huet. Recommendations for 186 drugs are presented according to the SPC (49.5%), DrugDex-Micromedex (26.3%) and WHO (18.8%) indications; six recommendations were based on specific publications; the theoretical recommendation based on pharmacokinetic parameters was proposed in four drugs. The final recommendations for clinical management were: dosage modification (26.9%), hepatic/analytical monitoring of the patient (8.6%), contraindication (18.8%), use with caution (19.3%) and no adjustment required (26.3%). In this review, specific recommendations for the practical management of patients with chronic liver disease are presented. It has been elaborated through a synthesis of the published bibliography and completed by following a theoretical methodology.

Recomendaciones para la dosificación de medicamentos en pacientes con insuficiencia hepática crónica / Drug dosage recommendations in patients with chronic liver disease

La insuficiencia hepática crónica produce alteraciones que afectan a la cinética de los medicamentos y a pesar de que su ajuste se basa en el índice Child-Pugh, no se disponen de recomendaciones y/o algoritmos de referencia que faciliten su dosificación. Se realizó una revisión bibliográfica de la dosificación en insuficiencia hepática crónica de los medicamentos de la guía del hospital incluidos en el listado de fármacos que la OMS recomienda no utilizar o utilizar con precaución en pacientes con enfermedad hepática, añadiendo las novedades terapéuticas de los últimos años. Para ello se revisaron las fichas técnicas, base DrugDex- Micromedex, recomendaciones de la OMS y artículos de revisión de los últimos 10 años en Medline; además, se calcularon los parámetros cinéticos de cada fármaco con el objeto de establecer una recomendación teórica basada en la propuesta de Delcò y Huet. Se presentan recomendaciones para 186 medicamentos, según lo indicado en la ficha técnica (49,5%), DrugDex-Micromedex (26,3%) y OMS (18,8%); 6 recomendaciones se realizaron en base a publicaciones específicas y en 4 fármacos se propuso la recomendación teórica basada en los parámetros farmacocinéticos. Las recomendaciones finales para el manejo clínico fueron de: modificación de dosis (26,9%), monitorización hepática/analítica del paciente (8,6%), contraindicación (18,8%), emplear con precaución (19,3%) y no requerir ajuste (26,3%). En esta revisión se presentan recomendaciones específicas para el manejo práctico del paciente con insuficiencia hepática crónica, obtenida mediante una síntesis de la bibliografía publicada y completada con aplicación de una metodología teórica(AU)
