[Failure mode effect analysis applied to preparation of intravenous cytostatics]. / Análisis modal de fallos y efectos aplicado a la elaboración de citostáticos intravenosos.

OBJECTIVE: To proactively identify risks in the preparation of intravenous cytostatic drugs, and to prioritise and establish measures to improve safety procedures. MATERIAL AND METHODS: Failure Mode Effect Analysis methodology was used. A multidisciplinary team identified potential failure modes of the procedure through a brainstorming session. The impact associated with each failure mode was assessed with the Risk Priority Number (RPN), which involves three variables: occurrence, severity, and detectability. Improvement measures were established for all identified failure modes, with those with RPN>100 considered critical. The final RPN (theoretical) that would result from the proposed measures was also calculated and the process was redesigned. RESULTS: A total of 34 failure modes were identified. The initial accumulated RPN was 3022 (range: 3-252), and after recommended actions the final RPN was 1292 (range: 3-189). RPN scores >100 were obtained in 13 failure modes; only the dispensing sub-process was free of critical points (RPN>100). A final reduction of RPN>50% was achieved in 9 failure modes. CONCLUSIONS: This prospective risk analysis methodology allows the weaknesses of the procedure to be prioritised, optimize use of resources, and a substantial improvement in the safety of the preparation of cytostatic drugs through the introduction of double checking and intermediate product labelling.

[The 2013 Seville Consensus Document on alternatives to allogenic blood transfusion. An update on the Seville Document]. / 2013. Documento Sevilla de Consenso sobre Alternativas a la Transfusión de Sangre Alogénica. Actualización del Documento Sevilla.

Since allogeneic blood transfusion (ABT) is not harmless, multiple alternatives to ABT (AABT) have emerged, though there is great variability in their indications and appropriate use. This variability results from the interaction of a number of factors, including the specialty of the physician, knowledge and preferences, the degree of anemia, transfusion policy, and AABT availability. Since AABTs are not harmless and may not meet cost-effectiveness criteria, such variability is unacceptable. The Spanish Societies of Anesthesiology (SEDAR), Hematology and Hemotherapy (SEHH), Hospital Pharmacy (SEFH), Critical Care Medicine (SEMICYUC), Thrombosis and Hemostasis (SETH) and Blood Transfusion (SETS) have developed a Consensus Document for the proper use of AABTs. A panel of experts convened by these 6 Societies have conducted a systematic review of the medical literature and have developed the 2013 Seville Consensus Document on Alternatives to Allogeneic Blood Transfusion, which only considers those AABT aimed at decreasing the transfusion of packed red cells. AABTs are defined as any pharmacological or non-pharmacological measure aimed at decreasing the transfusion of red blood cell concentrates, while preserving patient safety. For each AABT, the main question formulated, positively or negatively, is: « Does this particular AABT reduce the transfusion rate or not?¼ All the recommendations on the use of AABTs were formulated according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) methodology.

Biological treatments for moderate-to-severe psoriasis: indirect comparison.

WHAT IS KNOWN AND OBJECTIVE: Psoriasis is a chronic skin disease for which there is an increasing range of treatment options. Biological agents (ustekinumab, adalimumab, infliximab and etanercept) are indicated for moderate-to-severe plaque-type psoriasis in adults who fail to respond to, have a contraindication to, or are intolerant to other systemic therapies including cyclosporine, methotrexate and PUVA Unfortunately, with new drugs, the pivotal trials leading to their licensing are often placebo-controlled trials rather than comparative trials vs. established therapies. Therefore, inference on comparative effectiveness of the newer agents must be derived indirectly, through estimation of effects of the new agents vs. a common comparator. The objective of this study is to compare the relative efficacy of the biological agents through a systematic review of the indirect clinical trial evidence. METHODS: A systematic literature search was performed for clinical trials of biological agents in psoriasis. Pivotal, randomized, double-blind, controlled (placebo) trials using intention-to-treat analysis were selected for detailed analysis. Trials must include PASI 75 as a primary end point. The indirect comparison was performed using the method of Bucher adjusted with the ITC calculator (Indirect Treatment Comparisons of the Canadian Agency for Drugs and Technologies in Health), etanercept being the reference drug. We defined delta value for therapeutic equivalence as a difference in the efficacy of 25% among the different treatment options. RESULTS AND DISCUSSION: Fourteen studies (four for ustekinumab, three for adalimumab, three for infliximab and four for etanercept) were included. The indirect comparison results reveal that ustekinumab, adalimumab and infliximab were statistically superior to etanercept with an absolute risk difference for PASI 75 of 12% (95% CI = 5·9-18%), 11% (95% CI = 5·3-16·7%) and 24% (29·7-18·3%) respectively. However, in all situations, the 95% confidence interval does not achieve clinical relevance as no delta exceeds the previously set value (25%). WHAT IS NEW AND CONCLUSION: Ustekinumab, adalimumab, infliximab and etanercept can be regarded as clinical equivalents for the treatment of psoriasis. Choice between these agents therefore depends on their relative safety profiles, individual contra-indications and cost effectiveness.

[Off-label approval of drug use in a tertiary hospital]. / Autorización de usos de medicamentos fuera de indicación en un hospital de tercer nivel.

BACKGROUND AND OBJECTIVE: The Pharmacy and Therapeutics Committee (PTC) evaluates the requests for off-label uses with an abbreviated report format. The aim of this study is to perform a descriptive analysis of this activity and to study the rate of approvals. MATERIAL AND METHODS: A descriptive study was performed on the PTC reports in a tertiary hospital between September 2009 and April 2011. The type of drug by treatment group and by type of dispensing, indication and requesting department was analysed. The final decision adopted was studied as the primary outcome, and the percentage of requests approved according to the characteristics of the drug evaluated, indication requested, alternatives used, evidence and cost, as secondary outcomes. RESULTS: A total of 51 applications were analysed, of which 60.8% were drugs for hospital use and 54.9% cytostatic. The most requested indications were the onco-haematological (43.2%) and autoimmune (35.3%). Haematology was the department that made most requests (11 requests with 72.7% approved), Oncology and Paediatrics (both with 10 requests, with 50% approved). Almost two-thirds (60.8%) of the requests were approved. Of those that were not approved, 11 had not used up the therapeutic alternatives, and 8 had no evidence. Just under half (47.1%) of the drugs requested had a cost/patient between 10,000-100,000 euros,of which 58.3% were approved (cost per course of treatment if it had a defined period, or cost of treatment per year for chronic treatment). CONCLUSION: There is an increase in the activity of the PTC that is growing over the years. Most applications focus on drugs for hospital use and cytostatic drugs by Onco-haematology. There is a high rate of approval by the PTC, and high variability in the percentage of approval depending on the department and the evidence of use. The difference between approved and unapproved requests followed a logic of cost-effectiveness.

[Analysis of the selection process for new drugs in a tertiary hospital 2004-2007]. / Análisis del proceso de selección de nuevos medicamentos en un hospital terciario. Años 2004-07.

OBJECTIVE: The purpose of this study is to describe the structure of the CFyT, the Pharmacy and Therapeutics Committee, and a tertiary hospital's selection process for new drugs. MATERIAL AND METHODS: All annals of the P&TC and the New Drug Incorporation Guides (GINF) to incorporate new drugs received at Hospital Virgen del Rocío between 2004 and 2007 were reviewed. We carried out a descriptive study which collected variables having to do with the drug (drug type, type of register, route of administration and legal category), the petitioner (responsible division, professional category and request type) and the result of the evaluation (final decision, elapsed time between the request and the decision). RESULTS: Of the 72 requested drugs, 45 (62.5%) were approved: six as equivalent treatments, 36 (80%) with specific recommendations, and three (4.2%) with no restrictions. Twelve drugs (81.1%) were not included due to insufficient evidence of their effectiveness compared with the current treatment. The most frequently-requested drug type was the antineoplastics, most commonly requested by Oncology and Haematology divisions. We highlight the fact that many of the petitioners included clinical trials (97.2%) and data referring to costs (84.7%). CONCLUSIONS: There is a high level of compliance with the GINF guide in our centre, which guarantees that the P&TC's final decision is based on scientific evidence.

[Evaluation of drug treatment of myocardial infarction in public hospitals of Andalusia. GAUME (Andalusian Group for performance of Studies on Drug Utilization)]. / Evaluación del tratamiento farmacológico del infarto de miocardio en los hospitales públicos de Andalucía. GAUME (Grupo Andaluz para la realización de Estudios de Utilización de Medicamentos).

BACKGROUND: The management of patients with acute myocardial infarction (AMI) has changed over the last decade. The aim of this study was to evaluate the pharmacologic treatment of AMI in the clinical practice, with special emphasis in thrombolytic therapy. MATERIAL AND METHODS: Prospective drug utilization survey, collecting data from 26 hospitals belonging to the Andalusian Health Service, Spain, during one month period. Pharmacologic treatment in the first 24 h was obtained. RESULTS: Out of 379 patients recruited, 52.8% received thrombolytic therapy, although another 19% could have obtained some benefit from that therapy. Alteplase was the most frequently used thrombolytic (65.5%). The regimen prescribed was mainly that followed in GUSTO Study (45.8%) or double bolus (43.5%). In a high percentage of patients the thrombolytic selection was not made according to the results of the literature. Women and patients older than 75 years were less likely to receive thrombolytic therapy. There was a high utilization of aspirin (89.7%), nitrates (84.4%) and heparin (83.6%). CONCLUSIONS: Thrombolytic therapy was prescribed in a higher percentage of patients than is reported in other trials. In spite of that, thrombolytics should have been used in more patients. As alteplase does not have a definitive benefit over streptokinase, protocol is needed when selecting a thrombolytic agent.
