Developing a telepharmacy programme with home medication dispensing and informed delivery in a tertiary hospital: description of the model and analysis of the results.

OBJECTIVES: This study aimed to describe the actions taken to implement a telepharmacy programme with home medication dispensing and informed delivery in an outpatient pharmaceutical care unit of a tertiary hospital, where approximately 5000 patients are treated per year. It also aimed to substantiate the applicability and benefits of the programme through analysing the findings and measuring patient satisfaction. METHODS: We identified the operational, logistical, technological and legal needs, as well as the need for training, information and coordination with the care team and patient associations. A standard operating procedure was developed which described the home dispensing model and the profile of patients eligible for telepharmacy. Care activity was evaluated, between the months of July 2020 and January 2021; and a survey was conducted to measure patient satisfaction based on the Enopex project, a cross-sectional observational study of patients who used telepharmacy services during the COVID-19 lockdown period in Spain. RESULTS: A total of 2536 medication deliveries were made over 144 working days, with a mean of 18 (standard deviation (SD): 6) deliveries per day, and a total of 2854 dispensings (1.1 drugs per delivery). In total, 197 different types of pharmaceutical formulations were delivered, corresponding to 123 active ingredients. The distance and time avoided during the study period totalled 1 05 624 km and 1 09 452 min (76 days), whereby the median distance and time saved per patient were 66 (interquartile range (IQR):122 km and 90 (IQR:90) minutes, which represents an approximate carbon footprint reduction of 25 kg of CO2 per patient and 16.5 tonnes in total. The satisfaction survey conducted, completed by 134 patients, revealed high satisfaction with the pharmacy service of 9.88 points out of 10. CONCLUSIONS: The SARS-CoV-2 pandemic (COVID-19) has provided the pharmacy service with an opportunity to develop and implement a telepharmacy programme that benefits patients, which has enabled better organisation of the unit and greater accessibility for patients attending in person. It is a replicable method that is applicable in other pharmacy services with similar characteristics and requirements.

Observational study to evaluate discontinuation of monotherapy with cobicistat-boosted darunavir in patients with human immunodeficiency virus.

To evaluate the reasons for changing to monotherapy with protease inhibitors, together with the proportion and reasons for the interruption to treatment, in patients who have been treated at some point with cobicistat-boosted darunavir (DRV/c). Outpatients in a tertiary hospital. Observational retrospective study to evaluate monotherapy with DRV/c (800 mg/150 mg) in adult patients with human immunodeficiency virus infection, from December 2014 to July 2022. Demographic variables, viral load, cluster of differentiation 4 lymphocyte lymphocyte count, and antiretroviral therapy were assessed. 42 patients were included. 36% of the patients were undergoing monotherapy at the time of the analysis. The main reason for discontinuation was poor adherence. At time of analysis, 80% of the patients in monotherapy had an undetectable viral load. Antiretroviral therapy recommendations advise against exposing the patient to functional monotherapy with a single drug due to the high risk of virological failure and the onset of resistance to a single drug. Following the analysis of the results, DRV/c in monotherapy is not an effective strategy in the medium and long term due to factors such as lack of adherence or virological failure, although it can be maintained in specific circumstances. Therefore, patients undergoing monotherapy require close monitoring.

BK Virus-Associated Hemorrhagic Cystitis After Allogeneic Hematopoietic Stem Cell Transplantation in the Pediatric Population.

OBJECTIVE: To study the incidence, risk factors, and treatment of hemorrhagic cystitis secondary to BK-virus reactivation (HC-BKV) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the pediatric population. METHODS: Case-control study in which all pediatric patients (0-18 years) who underwent allo-HSCT from September 2009 to January 2014 were followed. RESULTS: Twenty-nine patients underwent an allo-HSCT. The median age was 9 years (range = 6 months to 15 years), 61% male. The primary diagnosis was acute lymphoblastic leukemia (72.4%). Six (20.7%) developed HC-BKV. In a multivariate analysis of risk factors, it was observed that the reactivation of BK virus was associated with age more than 10 years ( P = .098) and those with positive serology for Epstein-Barr virus ( P = .06). Five of the 6 patients with HC-BKV received cidofovir (CDV) at doses of 3 to 5 mg/kg/week. The treatment lasted a median of 3 cycles (range = 2-5). One of the patients (20%) developed nephrotoxicity. Of the 5 patients treated with CDV, 3 (60%) had a complete response, 1 (20%) partial response, and 1 (20%) no response. CONCLUSION: We conclude that HC-BKV is a frequent complication after allo-HSCT. CDV therapy can be effective but controlled clinical trials are needed.

Assessment of the quality of sample labelling for clinical research.

OBJECTIVE: To assess the quality of the labels for clinical trial samples through current regulations, and to analyze its potential correlation with the specific characteristics of each sample. METHOD: A transversal multicenter study where the clinical trial samples from two third level hospitals were analyzed. The eleven items from Directive 2003/94/EC, as well as the name of the clinical trial and the dose on the label cover, were considered variables for labelling quality. The influence of the characteristics of each sample on labelling quality was also analyzed. OUTCOME: The study included 503 samples from 220 clinical trials. The mean quality of labelling, understood as the proportion of items from Appendix 13, was of 91.9%. Out of these, 6.6% did not include the name of the sample in the outer face of the label, while in 9.7% the dose was missing. The samples with clinical trial-type samples presented a higher quality (p < 0.049), blinding reduced their quality (p = 0.017), and identification by kit number or by patient increased it (p < 0.01). The promoter was the variable which introduced the highest variability into the analysis. CONCLUSIONS: The mean quality of labelling is adequate in the majority of clinical trial samples. The lack of essential information in some samples, such as the clinical trial code and the period of validity, is alarming and might be the potential source for dispensing or administration errors.

Objetivo: Evaluar la calidad de las etiquetas de muestras para ensayos clínicos mediante la normativa vigente y analizar su posible correlación con las características específicas de cada muestra. Método: Estudio transversal multicéntrico en el que se analizaron las muestras de ensayos clínicos de dos hospitales de tercer nivel. Se estudió la presencia de los once ítems de la Directiva 2003/94/CE, el nombre del ensayo y la dosis en la portada de la etiqueta como variables de calidad del etiquetado. Se analizó la influencia de las características propias de la muestra con la calidad del etiquetado. Resultado: Se analizaron un total de 503 muestras de 220 ensayos. La calidad media del etiquetado, entendido como el porcentaje de ítems del Anexo 13, fue del 91,9%. El 6,6% no contenía el nombre de la muestra en la cara externa de la etiqueta, mientras que a un 9,7% les faltaba la dosis. Las muestras con presentación de tipo ensayo clínico presentaron mayor calidad (p < 0,049), el enmascaramiento disminuía la calidad (p = 0,017) y la identificación por número de kit o por paciente la aumentaban (p < 0,01). La variable promotor fue la que más variabilidad introdujo en el análisis. Conclusiones: La calidad media del etiquetado es adecuada en la mayoría de las muestras del ensayo clínico. Resulta preocupante la ausencia de información esencial, como el código del ensayo clínico y el período de validez, en algunas muestras que pueden ser fuente potencial de errores de dispensación o de administración.

[Applying dose banding to the production of antineoplastic drugs: a narrative review of the literature]. / Dose banding aplicado a la elaboración de antineoplásicos: una revisión narrativa de la literatura.

The dosage of antineoplastic drugs has historically been based on individualized prescription and preparation according to body surface area or patient´s weight. Lack of resources and increased assistance workload in the areas where chemotherapy is made, are leading to the development of new systems to optimize the processing without reducing safety. One of the strategies that has been proposed is the elaboration by dose banding. This new approach standardizes the antineoplastic agents doses by making ranges or bands accepting a percentage of maximum variation. It aims to reduce processing time with the consequent reduction in waiting time for patients; to reduce errors in the manufacturing process and to promote the rational drug use. In conclusion, dose banding is a suitable method for optimizing the development of anticancer drugs, obtaining reductions in oncologic patients waiting time but without actually causing a favorable impact on direct or indirect costs.

La dosificación de los fármacos antineoplásicos se ha basado históricamente en la prescripción y elaboración individualizada según la superficie corporal o peso del paciente. La falta de recursos y el aumento de la carga asistencial en las áreas de elaboración de quimioterapia están propiciando que se desarrollen nuevos sistemas que optimicen la elaboración sin reducir la seguridad. Una de las estrategias que se ha propuesto es la elaboración mediante dose banding. Este nuevo enfoque estandariza las dosis de antineoplásicos en rangos o bandas aceptando un porcentaje de variación máxima. Pretende reducir los tiempos de elaboración con la consiguiente reducción de los tiempos de espera de los pacientes, disminuir los errores en la elaboración y fomentar el uso racional de los fármacos. En definitiva, el dose banding es un método adecuado para la optimización de la elaboración de antineoplásicos, obteniendo reducciones del tiempo de espera de los pacientes oncológicos, aunque sin llegar a causar un impacto favorable sobre los costes directos o indirectos.

[Quality and legibility of written informed consent form in pharmacogenetic research]. / Calidad y Legibilidad de la Hoja de Información al Paciente en Estudios con Análisis Farmacogenético.

BACKGROUND AND OBJECTIVE: Pharmacogenetic studies have become in recent years a common practice in the development of new drugs, with the need to evaluate the information and readability of Informed Consent Forms(ICFs) to ensure compliance with the recommendations set by current legislation and expert groups. MATERIALS AND METHODS: Retrospective observational study that analyzes the content of ICFs received by participants of pharmacogenetic studies approved in a tertiary hospital. To evaluate the quality of the ICFs, a questionnaire of 42 questions was prepared (Table 1) with the elements that must contain the information given to subjects, while readability was assessed using different readability indices. RESULTS: The 31.5% of the 92 ICFs analyzed showed more than 75% of sections considered in the questionnaire. Sections with lower compliance were relative to risks and benefits (41.7%) and compensation for study participation (56.1%). None of the ICFs fulfilled with less than 50% of overall sections. Regarding legibility, about 90%, have a suitable degree for the most of population based on indexes used. CONCLUSIONS: Deficiencies were found in some parts of the information contained in ICFs, while the degree of legibility was high, being necessary for future studies to establish the degree of real understanding of patients.
