Haemorrhagic complications in patients with renal insufficiency during treatment or prophylaxis with dalteparin.

OBJECTIVES: Low-molecular-weight heparins are widely used in clinical practice for the treatment or prophylaxis of venous thromboembolism (VTE). As these drugs are eliminated mainly by renal means, any renal function impairment may lead to higher plasma concentrations and increase the risk of bleeding. This study aims to evaluate whether in clinical practice there is an increase in the occurrence of bleeding in patients with renal insufficiency (RI) during treatment or prophylaxis with dalteparin, and to analyse the risk factors potentially influencing the appearance of such bleeding events. METHODS: Patients were sampled from the Universitary Severo Ochoa Hospital, Leganés, Spain. This was a retrospective cohort study with a 1 year inclusion period, conducted at a Spanish university hospital with 400 beds, on patients undergoing treatment or prophylaxis for VTE with dalteparin for a minimum of 3 days. The main outcome measure was the number of patients who had bleeding events, independently of their severity, during dalteparin administration in patients with RI. RESULTS: 367 patients were included in the study. Bleeding occurred in 17.9% of patients in the group with RI and in 7.3% of patients with normal renal function (NRF). Most haemorrhages in both cohorts were grade 2 on the WHO scale (64.7% in the RI group and 69.2% in the NRF group). Logistic regression analysis allowed the presence of RI (MDRD-4 (Modification of Diet in Renal Disease) <50 mL/min) to be identified as a risk factor. CONCLUSION: Patients with RI treated with dalteparin face a higher risk of bleeding than those with NRF, which seems to make it necessary to monitor and seek new dosage adjustments for these patients.Impact on practice statements: This study yields new data on dalteparin in RI, which has not been widely studied before.

Assessment of exposure-response relationship for bevacizumab in patients with metastatic colorectal cancer.

Limited literature is available for bevacizumab exposure-response relationship and there is not a concentration threshold associated with an optimal disease control. This prospective observational study in patients with metastatic colorectal cancer (mCRC) aims to evaluate, in a real-life setting, the relationship between bevacizumab through concentrations at steady state (Ctrough, SS) and disease control. Ctrough, SS were drawn, coinciding with the radiological evaluation of the response (progression or clinical benefit). Generalized estimating equations (GEE) analysis was performed. To test the association between Ctrough, SS in each patient with overall survival (OS) or progression-free survival (PFS), Cox proportional hazard models were developed. Data included 50 bevacizumab Ctrough, SS from 27 patients. The GEE model did not suggest any positive association between bevacizumab Ctrough, SS and clinical benefit (OR 0.99, 95% CI: 0.98-1.02, p = 0.863). The Cox regression showed association between higher median Ctrough, SS with better OS (HR 0.86, 95% CI: 0.73-1.01, p = 0.060), but not with PFS. We cannot confirm a relationship between bevacizumab Ctrough, SS and clinical benefit but this is the first real-world study trying to show a relationship between bevacizumab Ctrough, SS and disease control in mCRC. It was conducted in a small sample size which reduces the level of evidence. Further controlled randomized studies with a sufficient number of patients are required.

Error Detection and Cost Savings With an Image-Based Workflow Management System Connected to a Computerized Prescription Order Entry Program for Antineoplastic Compounding.

OBJECTIVE: The aim of the study was to analyze both the prevalence of errors with the implementation of an image-based workflow management system during the antineoplastic compounding process, and the estimated costs associated with the negative clinical outcome if the errors had not been intercepted. METHODS: Three months after the implementation of Phocus Rx system at a hospital pharmacy department, the identification, classification (type, preparation stage, and cause), and potential severity degree (from negligible to catastrophic) of the errors intercepted were determined. The probability of an error causing an adverse event if it had reached the patient (from nil [0] to high [0.6]) and its consequences was estimated by a team of clinical pharmacists and physicians. Cost-effectiveness analysis from the hospital's perspective was performed. RESULTS: Overall, 9872 antineoplastic medications were prepared using Phocus Rx. The total compounding error rate was 0.8% (n = 78, 56 [69.2%] were related to incorrect dose, 20 [28.2%] to incorrect drug preparation or conditioning technique, and 2 [2.6%] were wrong drugs). Approximately 70% of the detected errors were classified as undetectable via the previous verification practice, with 11.55% judged to be potentially severe (n = 9) and 51.3% moderate (n = 29). Likelihood of occurrence of an adverse event was medium (0.4) to high (0.6) for 37.2% of the errors. Estimated cost ratio and return on investment were €4.21 and 321%, respectively. CONCLUSIONS: The implementation of Phocus Rx prevented antineoplastic preparation errors that would have reached the patient otherwise. In addition, acquisition of this technology was estimated to be cost-effective.

Potentially inappropriate medication in acute hospitalized elderly patients with polypharmacy: an observational study comparing PRISCUS, STOPP, and Beers criteria.

PURPOSE: To compare the prevalence of potentially inappropriate medication (PIM) in the elderly according to the PRISCUS list, STOPP criteria, and Beers criteria. Secondary, to describe the differences using the three criteria focused on the inappropriate prescription of psychotropic drugs in the elderly. METHODS: A retrospective study was performed at Severo Ochoa University Hospital. The study included 365 patients, aged 80 years and older, living in Madrid, Spain. RESULTS: 93.42% of patients received at least one PIM during hospitalization. Using the PRISCUS list, this changed from 32.6 to 2.7% at discharge. Applying STOPP criteria lowered the percentage from 65.20 to 10.95%, and with Beers criteria from 80.27 to 10.13. Lower Barthel index at admission was associated with an increased relative risk for receiving at least one PIM (OR 1.79, 95% CI 1.15-2.80, p = 0.024) using PRISCUS list as a tool in conjunction with STOPP criteria (OR 1.44, 95% CI 0.89-2.33, p = 0.037). Polypharmacy at admission predicted the presence of PIMs with STOPP criteria (OR 1.74, 95% CI 1.07-2.84, p = 0.001). Regarding psychotropic medicines, 208 patients (56.98%) received at least one psychotropic medicine during hospitalization. A total of 26.30% of patients were treated with psychotropic medicines, detected by the PRISCUS list, and 53.97% and 29.85% with STOPP and Beers, respectively. CONCLUSIONS: Explicit criteria are a useful tool for identifying during hospitalization of the elderly patients. As indicated by the results, new research is needed to carry out an adaptation in our country that includes an evaluation of the strengths of the three tools to decrease PIMs and improve prescription in the elderly.

Effect of a Mobile App for the Pharmacotherapeutic Follow-Up of Patients With Cancer on Their Health Outcomes: Quasi-Experimental Study.

BACKGROUND: Oral antineoplastic agents (OAAs) have revolutionized cancer management. However, they have been reported with adverse side effects and drug-drug interactions. Moreover, patient adherence to OAA treatment is critical. Mobile apps can enable remote and real-time pharmacotherapeutic monitoring of patients, while also promoting patient autonomy in their health care. OBJECTIVE: The primary objective was to analyze the effect of using a mobile app for the follow-up of patients with oncohematological malignancies undergoing treatment with OAAs on their health outcomes. The secondary objectives were to analyze the role of the app in communication with health care professionals and patient satisfaction with the app. METHODS: We performed a comparative, quasi-experimental study based on a prepost intervention with 101 patients (control group, n=51, traditional pharmacotherapeutic follow-up vs intervention group, n=50, follow-up through e-OncoSalud, a custom-designed app that promotes follow-up at home and the safety of patients receiving OAAs). The effect of this app on drug safety, adherence to treatment, and quality of life was evaluated. RESULTS: With regard to drug safety, 73% (37/51) of the patients in the control group and 70% (35/50) of the patients in the intervention group (P=.01) presented with drug-related problems. The probability of detecting an insufficiently treated health problem in the intervention group was significantly higher than that in the control group (P=.04). The proportion of patients who presented with side effects in the intervention group was significantly lower than that in the control group (P>.99). In the control group, 49% (25/51) of the patients consumed some health resources during the first 6 months of treatment compared with 36% (18/50) of the patients in the intervention group (P=.76). Adherence to treatment was 97.6% (SD 7.9) in the intervention group, which was significantly higher than that in the control group (92.9% [SD 10.0]; P=.02). The EuroQol-5D in the intervention group yielded a mean (SD) index of 0.875 (0.156), which was significantly higher than that in the control group (0.741 [0.177]; P<.001). Approximately 60% (29/50) of the patients used the messaging module to communicate with pharmacists. The most frequent types of messages were acknowledgments (77/283, 27.2%), doubts about contraindications and interactions with OAAs (70/283, 24.7%), and consultations for adverse reactions to treatment (39/283, 13.8%). The satisfaction with the app survey conducted in the intervention group yielded an overall mean (SD) score of 9.1 (0.4) out of 10. CONCLUSIONS: Use of e-OncoSalud for the real-time follow-up of patients receiving OAAs facilitated the optimization of some health outcomes. The intervention group had significantly higher health-related quality of life and adherence to treatment than the control group. Further, the probability of the intervention group presenting with side effects was significantly lower than that of the control group.

Exposición a fármacos asociados a agravamiento de síntomas en pacientes con miastenia grave / Drug exposure associated with exacerbation of symptoms in patients with myasthenia gravis

INTRODUCCIÓN: Numerosos fármacos se han relacionado con el agravamiento de síntomas en pacientes con miastenia grave, pero hasta la fecha no existen estudios sobre la exposición a fármacos en estos pacientes. OBJETIVOS: Describir el consumo de fármacos y calcular la tasa anual de episodios de exacerbación en una cohorte de pacientes con miastenia grave, y explorar posibles factores de riesgo de exacerbaciones graves. PACIENTES Y MÉTODOS: Estudio observacional longitudinal retrospectivo que incluye a pacientes adultos con miastenia grave seguidos en consulta. Cálculo de frecuencias, tasas y construcción de modelo de eventos repetidos. RESULTADOS: De 91 pacientes incluidos, el 94,51% estuvo expuesto al menos a un fármaco durante el período de estudio (siete años y un mes). De ellos, 51 tuvieron al menos una prescripción de un fármaco contraindicado en la ficha técnica (56,04%). Se contabilizaron 145 exacerbaciones en 50 pacientes. La tasa anual de incidencia fue de 0,35 exacerbaciones por paciente y año. De estas exacerbaciones, 48 fueron graves (en 18 pacientes), con una tasa anual de incidencia de 0,12. Se halló una posible asociación entre diagnóstico de miastenia grave generalizada y timectomía, con un aumento del riesgo de episodios de exacerbación graves. CONCLUSIONES: En esta cohorte se encontró una amplia exposición a fármacos, pero no asociación con el riesgo de episodios de exacerbación graves. Algo más de la mitad de pacientes tuvo al menos un episodio de exacerbación durante el período de estudio, la mayoría leves. Son necesarios estudios que corroboren estas conclusiones y puedan estudiar posibles correlaciones entre fármacos y el riesgo de episodios de exacerbación

INTRODUCTION: Numerous drugs have been related to exacerbation of myasthenia gravis. So far there are no studies examining the extent of use of drugs related to exacerbation of myasthenia gravis. AIMS: We sought to assess the extent of use of drugs related to exacerbations and the annual incidence rate of exacerbations in a cohort of myasthenia gravis patients. We explored possible risk factors of severe exacerbations. PATIENTS AND METHODS: We performed a retrospective cohort study. We included adult patients followed in neurology department. We estimated frequencies, rates and built a recurrent events model. RESULTS: We included 91 patients. 94.51% of patients had at least one prescription of a drug. 51 patients had at least one prescription of a drug contraindicated according to its drug label. 145 exacerbation episodes were reported in 50 patients. The annual incidence rate of exacerbation episodes was 0.35. 48 exacerbations were severe (in 18 patients). The annual incidence rate of severe exacerbation episodes was 0.12. Generalized myasthenia gravis and thymectomy were associated with a higher risk of severe exacerbation episodes. CONCLUSIONS: Our patients were extensive and widespread exposed to drugs during the follow-up period but we did not find and association with severe exacerbation episodes. Just over half of the patients had at least one exacerbation episode during the study period, most of them were mild. Further studies with larger sample sizes are necessary to corroborate these conclusions and to study possible correlations between the use of drugs and the risk of exacerbation episodes

Necesidades sociosanitarias en pacientes con intolerancia hereditaria a la fructosa en España / Social and health care needs in patients with hereditary fructose intolerance in Spain

INTRODUCCIÓN: La intolerancia hereditaria a la fructosa es una enfermedad metabólica debida a una deficiencia en la aldolasa B. Nuestro objetivo es conocer las necesidades sociosanitarias del colectivo. METODOLOGÍA: Estudio observacional prospectivo en el que se difundió una encuesta de necesidades sociosanitarias a pacientes con intolerancia hereditaria a la fructosa residentes en España. RESULTADOS: La mayoría disponían de diagnóstico, confirmado principalmente por análisis genético en menores y sobrecarga de fructosa en adultos, no padecían secuelas (72,34%) ni discapacidad (64%) y el 83,33% de niños tomaban medicamentos frente al 52,38% de adultos (p < 0,05) (2,06 medicamentos de media). La mayoría acudieron a consultas en los dos últimos años, principalmente unidades de enfermedades metabólicas (42,5%) y/o nutricionista (42,5%), aunque menos de la mitad eran atendidos en centros de referencia (mayoritariamente niños [p < 0,05]). El 48% estaban satisfechos con la atención sanitaria aunque se sintieron discriminados en actividades de ocio, escolares, sanitarias y/o cotidianas. Las fuentes más fiables de información fueron el médico de atención especializada (69,39%) y la asociación de pacientes (59,18%). El 54% no indicaron ningún problema en ninguna de las dimensiones de calidad de vida, aunque algunos tuvieron problemas en actividades cotidianas, dolor y ansiedad. CONCLUSIONES: Aunque su perfil no sea tan discapacitante como el de otras enfermedades raras, es importante conocer las necesidades del paciente con intolerancia hereditaria a la fructosa. Aunque se han reducido los tiempos en el diagnóstico, la menor atención y satisfacción sanitaria en adultos hace necesario incidir en las necesidades de esta población, siendo clave la formación e información de los profesionales sanitarios

INTRODUCTION: Hereditary fructose intolerance is a metabolic disease due to an aldolase B deficiency. Our objective was to ascertain the social and health care needs of those with this deficiency. MATERIAL AND METHODS: A prospective, observational study was performed. A survey of social and health care needs was conducted to hereditary fructose intolerance patients living in Spain. RESULTS: Most patients had been diagnosed, mainly by genetic analysis in children and based on fructose overload in adults. Population surveyed had no sequelae (72.34%) or disability (64%), and 83.33% of children and 52.38% of adults were taking drugs (p < .05) (2.06 drugs on average). Most patients had attended medical visits in the past two years, mainly in metabolic disease units (42.5%) and/or nutrition units (42.5%), but less than a half attended reference centers (mostly children [p < 0.05]). Although 48% were satisfied with health care, they felt discriminated in recreational activities, school, health and/or daily activities. The most reliable sources of information were the specialized care physician (69.39%) and patients' association (59.18%). Fifty-five percent reported no problem in any quality of life dimension, although some had problems in daily activities, pain, and anxiety. CONCLUSIONS: Although hereditary fructose intolerance is less disabling than other rare diseases, it is important to know the needs of those who suffer from it. Although time to diagnosis has shortened, the poorer health care and satisfaction with it perceived in adults makes it necessary to emphasize the needs of this population, and the critical need of training and information of health care professionals

Risks and medication errors analysis to evaluate the impact of a chemotherapy compounding workflow management system on cancer patients' safety.

A failure modes, effects and criticality analysis was supported by an observational medication error rate study to analyze the impact of Phocus Rx®, a new image-based workflow software system, on chemotherapy compounding error rates. Residual risks that should be a target for additional action were identified and prioritized and pharmacy staff satisfaction with the new system was evaluated. In total, 16 potential failure modes were recognized in the pre-implementation phase and 21 after Phocus Rx® implementation. The total reduction of the criticality index was 67 percent, with a reduction of 46 percent in material preparation, 76 percent in drug production and 48 percent in quality control subprocesses. The relative risk reduction of compounding error rate was 63 percent after the implementation of Phocus Rx®, from 0.045 to 0.017 percent. The high-priority recommendations defined were identification of the product with batch and expiration date from scanned bidimensional barcodes on drug vials and process improvements in image-based quality control. Overall satisfaction index was 8.30 (SD 1.06) for technicians and 8.56 (SD 1.42) for pharmacists (p = 0.655). The introduction of a new workflow management software system was an effective approach to increasing safety in the compounding procedures in the pharmacy department, according to the failure modes, effects and criticality analysis method.

Measure of adherence to direct-acting antivirals as a predictor of the effectiveness of hepatitis C treatment.

Background Adherence to direct-acting antivirals could be a predictor response to these treatments in hepatitis C. Objective To assess the ability of three methods of measuring adherence to direct-acting antivirals [pill counts, pharmacy dispensing record and Simplified Medication Adherence Questionnaire (SMAQ)] as predictors of their effectiveness. Setting Study conducted by the pharmacy department of the hospital. Methods: A retrospective study was performed. Patients ≥ 18 years with hepatitis C that started and completed treatment with direct-acting antivirals between the 1st-April-2015 and 28st-February-2016 were enrolled. To evaluate the predictive ability to obtain a response to treatment, Chi squared test, Mann-Whitney-U test and ROC-curves were used. Main outcome measure Adherence to antivirals was assessed by three methods and response to treatment, which was defined as obtaining a viral load of hepatitis C virus ≤ 15UI/ml at week 12 after the end of treatment. Results 128 patients were enrolled. The overall average adherence obtained with SMAQ (99.09%) was similar to the pill counts (96.40%, p = 0.043) and pharmacy dispensing record (91.10%, p = 0.02). There was no correlation between the percentage of patients considered as adherent by SMAQ (99.09%) and the achievement of response to treatment (96.40%, p = 0.999). The ROC-curve obtained for the pill count method shows a global area under the curve of 0.53. For pharmacy dispensing record method, patients with an adherence ≤ 66.66% have a high probability of not achieving response (sensitivity and specificity of 79.00% and 100.00%, respectively). Conclusions Pharmacy dispensing record is shown as the best indicator of adherence to predict therapeutic failure in our study.

Development and Evaluation of a Clinical Decision Support System to Improve Medication Safety.

BACKGROUND: Clinical decision support systems (CDSSs) are a good strategy for preventing medication errors and reducing the incidence and severity of adverse drug events (ADEs). However, these systems are not very effective and are subject to multiple limitations that prevent their implementation in clinical practice. OBJECTIVES: The objective of this study was to evaluate the effectiveness of an advanced CDSS, HIGEA, which generates alerts based on predefined clinical rules to identify patients at risk of an ADE. METHODS: A multidisciplinary team defined the system and the clinical rules focusing on medication errors commonly encountered in clinical practice. Four intervention programs were defined: (1) dose adjustment in renal impairment; (2) adjustment of anticoagulation/antiplatelet therapy; (3) detection of biochemical/hematologic toxicities; and (4) therapeutic drug monitoring. We performed a 6-month observational prospective study to analyze the effectiveness of these clinical rules by calculating the positive predictive value (PPV). RESULTS: The team defined 211 clinical rules. During the study period, HIGEA generated 1,086 alerts (8.9 alerts per working day), which were reviewed by pharmacists. Fifty-one percent (554/1,086) of alerts generated an intervention to prevent a possible ADE; of these, 66% (368/554) required a documented modification to therapy owing to a real prescription error intercepted. The intervention program that induced the highest number of modifications to therapy was the dose adjustment in renal impairment program (PPV = 0.51), followed by the adjustment of anticoagulation/antiplatelet therapy program (PPV = 0.24). The percentage of accepted interventions was similar in surgical units (68%), medical units (67%), and critical care units (63%). CONCLUSION: Our study offers evidence that HIGEA is highly effective in preventing potential ADEs at the prescription stage.

Implementation of a pharmaceutical care program for patients with hepatitis C treated with new direct-action antivirals.

Background A pharmaceutical care program is necessary to improve the management of direct-acting antivirals in hepatitis C. Objective Describe health outcomes obtained with the implementation of a pharmaceutical care program in Hepatitis C patients treated with direct-acting antivirals. Setting This study was performed in a pharmacy department of a university hospital. Methods Retrospective study between 1st-April 2015 and 28st-February 2016. Hospital pharmacists implemented interventional measures for validation of antivirals prescriptions, detection of drug-interaction, adverse drug events, education and patient´s adherence to antiviral regimen. Main outcome measure Health and quality outcomes of the implementation of the pharmaceutical care program. Results A total 128 patients were enrolled. The overall sustained virologic response at week 12 post-treatment rate was 96.1% (95% CI 92.7-99.5). Adverse drug events occurred in 90.6% of the patients, and the majority were grade 1-2. Pharmacists made 334 pharmaceutical interventions. 35.5% of these interventions were aimed to resolve negative results of drugs. 80.9% of the negative results of drugs improved or were eliminated with the application of the measures proposed by the pharmacists (p ≤ 0.001). Pharmacists carried out 175 preventive interventions to avoid negative results of drugs. 97.3% of these interventions were accepted and managed to prevent the appearance of negative results of drugs (p = 0.453). Conclusion The implementation of a pharmaceutical care program in patients with hepatitis C treated with direct-acting antivirals has improved the safety in the use of these drugs.

Robotic dispensing improves patient safety, inventory management, and staff satisfaction in an outpatient hospital pharmacy.

RATIONALE, AIMS AND OBJECTIVES: Implementation of robotic systems in outpatient hospital pharmacies is uncommon. Other than cost, 1 of the barriers to widespread adoption is the lack of definitive evidence that this technology actually reduces dispensing errors and improves inventory management. OBJECTIVE: To identify the frequency of medication dispensing errors before and after the implementation of a robotic original pack dispensing system in an outpatient hospital pharmacy and to analyse the impact of this system on the quality of stock management and staff satisfaction. METHODS: A prospective before-and-after medication error study was performed using a disguised observation technique. Several indicators of stock management and staff satisfaction were monitored. Drugs were dispensed manually by technicians using a barcode-controlled system (preimplementation phase) or the dispensing robot ROWA Vmax (ARX) (postimplementation phase). As not all drugs could be handled by the robot, residual manual dispensing was also used. RESULTS: The dispensing error rate was reduced from 1.31% of prescriptions (43/3284) to 0.63% (19/3004) (relative risk reduction [RRR], 51.7%; 95% CI, 17.3% to 71.8%). The error rate decreased up to 0.12% (3/2496) (RRR, 90.8%; 95% CI, 70.4% to 97.1%) if errors during residual manual dispensing were excluded. The stock-out ratio was reduced from 0.85% to 0.17% (RRR, 80.5%; 95% CI, 49.5% to 92.5%). Daily staff time (median) in stock management was reduced by 59.3% (from 1 hour 36 minutes to 39 minutes). High level of staff satisfaction with this technology was achieved, although it was slightly higher in the group of pharmacists compared to technicians (8.63 ± 0.7 vs 7.78 ± 0.7, P = .046). CONCLUSION: The implementation of a robotic original pack dispensing system substantially decreased the rate of dispensing errors and optimized stock management. Minimizing the number of drugs out of the dispensing robot is critical when attempting to maximize the benefits of its implementation.

Component-resolved diagnosis in allergic disease: Utility and limitations.

Component resolved diagnosis (CRD) is a microarray-based diagnostic solution capable of simultaneously analysing specific IgE antibodies against 112 allergenic components, providing sensitivity patterns for multi-sensitised or complex patients. The CRD is indicated for these patients, especially those with concomitant respiratory and food allergies. This study reivews the method, its utility, limitations, and our experience in allergic diseases with difficult etiologic diagnosis (eosinophilic esophagitis, occupational asthma and drug allergy).

A comparative study of contamination in three closed systems for the preparation of hazardous drugs through simulations with fluorescein / Estudio comparativo de contaminación de tres sistemas cerrados para la preparación de fármacos peligrosos mediante simulación con fluoresceína

Objective: The objective of this study was to compare the environmental contamination generated during the preparation of cytostatic agents using three different methods through simulations using fluorescein, and the time required for preparation of each method. Method: A comparative study of the processing of fluorescein mixtures using three types of closed systems was conducted at the centralized unit for hazardous drugs of the Pharmacy Department of a General Teaching Hospital. Environmental contamination was detected in critical points of connection, and in splashes produced at any other points. The main variable was qualitative detection of contamination through ultraviolet light when three methods were compared (method A: ChemoClave(R), method B: SmartSite(R)valve and Texium(R)connector, method C: PhaSealTMwith BD luer extension). A final number of 60 mixtures were prepared to detect differences of at least 5%. Results: Qualitative contamination at the critical points during preparation, was seen in groups A and B for every mixture that was processed. No contamination at all in critical points was seen in any of the mixtures prepared using PhaSealTM. Statistically significant differences were found between arms A and C (p < 0.001) and arms B and C (p < 0.001); no differences were found between arms A and B. Conclusions: The combination of PhaSealTMsystem in conjunction with the BD luer extension for administering hazardous drugs from a tree modality system has been shown to be the system with the lowest level of contamination during processing without increasing the time required for preparation of the mixture

Objetivo: El objetivo de este estudio fue comparar la contaminación ambiental generada durante la preparación de fluoresceína y el tiempo de preparación usando tres sistemas cerrados de transferencia diferentes. Método: Estudio comparativo de elaboración de mezclas de fluoresceína con tres tipos de sistemas cerrados en una unidad de mezclas peligrosas de un Servicio de Farmacia de un Hospital General Universitario. Se consideró contaminación ambiental la detectada en los puntos críticos de conexión y las salpicaduras generadas en cualquier otro punto distinto. La variable principal fue la detección cualitativa mediante luz ultravioleta de la contaminación generada cuando se comparan tres sistemas (sistema A: ChemoClave(R), sistema B: válvula SmartSite(R)y conector Texium(R), sistema C: PhaSealTMcon alargadera luer BD). Se prepararon 60 mezclas para poder detectar diferencias de al menos el 5%. Resultados: Se detectó contaminación en los puntos críticos durante la preparación en todas las mezclas de los grupos A y B. No se detectó contaminación en ninguna de las mezclas en las que se usó el sistema cerrado PhaSealTM. Se encontraron diferencias estadísticas entre los grupos A y C (p < 0,001) y entre los grupos B y C (p < 0,001); no se encontraron diferencias entre los grupos A y B. Conclusiones: La combinación del sistema PhaSealTMy la alargadera luer BD para administrar fármacos peligrosos en la modalidad de árbol ha mostrado ser el sistema con el menor nivel de contaminación durante la preparación, sin que esto se traduzca en aumento en el tiempo de elaboración

A comparative study of contamination in three closed systems for the preparation of hazardous drugs through simulations with fluorescein.

OBJECTIVE: The objective of this study was to compare the environmental contamination generated during the preparation of cytostatic  agents using three different methods through simulations using fluorescein, and  the time required for preparation of each method. METHOD: A comparative study of the processing of fluorescein mixtures using three types of closed systems was conducted at the centralized unit for  hazardous drugs of the Pharmacy Department of a General Teaching Hospital. Environmental contamination was detected in critical points of  connection, and in splashes produced at any other points. The main variable was  qualitative detection of contamination through ultraviolet light when three  methods were compared (method A: ChemoClave®, method B: SmartSite®  valve and Texium® connector, method C: PhaSealTM with BD luer extension). A  final number of 60 mixtures were prepared to detect differences of at least 5%. RESULTS: Qualitative contamination at the critical points during preparation, was  seen in groups A and B for every mixture that was processed. No contamination  at all in critical points was seen in any of the mixtures prepared using  PhaSealTM. Statistically significant differences were found between arms A and  C (p < 0.001) and arms B and C (p < 0.001); no differences were found  between arms A and B. CONCLUSIONS: The combination of PhaSealTM system in conjunction with the BD  luer extension for administering hazardous drugs from a tree modality system  has been shown to be the system with the lowest level of contamination during  processing without increasing the time required for preparation of the mixture.

Objetivo: El objetivo de este estudio fue comparar la contaminación ambiental  generada durante la preparación de fluoresceína y el tiempo de preparación  usando tres sistemas cerrados de transferencia diferentes.Método: Estudio comparativo de elaboración de mezclas de fluoresceína con  tres tipos de sistemas cerrados en una unidad de mezclas peligrosas de un  Servicio de Farmacia de un Hospital General Universitario. Se consideró  contaminación ambiental la detectada en los puntos críticos de conexión y las  salpicaduras generadas en cualquier otro punto distinto. La variable principal fue  la detección cualitativa mediante luz ultravioleta de la contaminación  generada cuando se comparan tres sistemas (sistema A: ChemoClave®, sistema  B: válvula SmartSite® y conector Texium®, sistema C: PhaSealTM con  alargadera luer BD). Se prepararon 60 mezclas para poder detectar  diferencias de al menos el 5%.Resultados: Se detectó contaminación en los puntos críticos durante la  preparación en todas las mezclas de los grupos A y B. No se detectó contaminación en ninguna de las mezclas en las que se usó el sistema  cerrado PhaSealTM. Se encontraron diferencias estadísticas entre los grupos A y  C (p < 0,001) y entre los grupos B y C (p < 0,001); no se encontraron diferencias entre los grupos A y B.Conclusiones: La combinación del sistema PhaSealTM y la alargadera luer BD  para administrar fármacos peligrosos en la modalidad de árbol ha mostrado ser  el sistema con el menor nivel de contaminación durante la preparación, sin que  esto se traduzca en aumento en el tiempo de elaboración.

Twelve weeks of ombitasvir/paritaprevir/r and dasabuvir without ribavirin is effective and safe in the treatment of patients with HCV genotype 1b infection and compensated cirrhosis: results from a real-world cohort study.

OBJECTIVE: To explore the effectiveness and safety of ombitasvir/paritaprevir/ritonavir and dasabuvir (OBV/PTV/r+DSV) for 12 weeks without ribavirin in adults with chronic HCV genotype 1b infection and compensated cirrhosis. METHODS: Observational study of a prospective cohort of adult patients with HCV genotype 1b infection and compensated cirrhosis who received 12 weeks of OBV/PTV/r and DSV without ribavirin. Effectiveness was assessed by recording the percentage of patients achieving sustained virological response at week 12 post-treatment (SVR12). Safety outcomes were based on the incidence of adverse events. RESULTS: Seventy-eight patients were included. The SVR12 rate was 96.1% (95%CI 89.2-99.2). Adverse events were recorded in 78.0% of patients. Of these, 97.7% were grade 1/2. One patient discontinued treatment prematurely owing to adverse events. Eighty-six interactions were detected in 43 patients (55.1%). Overall, 81.4% of interactions required close monitoring, alteration of drug dosage, or timing of administration. In 7.0% of cases, the interactions arose from contraindications that required the suspension of the concomitant drug. In 11.6% of cases, medicinal plants or foods were withdrawn. CONCLUSIONS: The simplified regimen of OBV/PTV/r+DSV administered for 12 weeks is effective and safe in patients with chronic HCV genotype 1b infection and compensated cirrhosis. No adverse reactions related to drug-drug interactions were recorded.
