Objective: To quantify the Spanish Pharmacy and Therapeutics Committees (P&TC) activity with regard to assessing and selecting drugs and describing variability in decisions made to include them., Method: Descriptive, cross-sectional study based on a questionnaire aimed to 513 hospitals with more than 75 beds. We included questions referring to the P&TC resolutions, the therapeutic positioning and assessment reports. Recruitment was carried out between November 2007 and January 2008. Variability among P&TC conclusions were presented in five categories or levels of coincidence., Results: One hundred and seventy-five hospitals participated, with a response rate of 34% (54% of beds). The mean (SD) number of drug-indications assessed per hospital was 10.35 (7.45). The proportion of assessments that conclude with drug inclusion or rejection was 75.3 and 21.4%, respectively. 16.2% concluded with therapeutic equivalence. Conditions for use were established for 64% of them, and 33% were included in a clinical guide. With regard to variability, 81.0% of assessments coincided with the conclusion to include or reject the drug. A contradictory decision was made for 19.0%., Conclusions: Drug assessment and selection activity in hospitals involve an amount of work. The proportion of drugs approved is similar in different types of hospitals. There is extensive variability as regards deciding upon inclusion and is similar to studies conducted in other countries. They indicate that a standardising methodology would be recommendable., (Copyright © 2010 SEFH. Published by Elsevier Espana. All rights reserved.)

Aim of the Review: To review the literature on the structure and operation of hospital Pharmacy and Therapeutics Committees from an international point of view and examine the factors that influence decision-making of these committees., Method: We performed a literature search in the Medline and Embase databases from 1997 to January 2009 with the search terms: formulary system decision making, pharmacy and therapeutics committee, formularies hospital, drug formulary, survey, drug selection and outcome assessment health care. Inclusion criteria were the following: studies analyzing Pharmacy and Therapeutics Committees published in English or Spanish from 1997 to January 2009. Exclusion criteria were: publications which were editorials or opinion pieces, studies relating to one hospital, and studies where full text could not be attained. The analysis was divided into structural/organizational data and data on factors affecting the decision-making process., Results: Seventeen studies met the inclusion criteria. Pharmacy and Therapeutics Committees and formularies were present in more than 90% of the hospitals in four of the five countries examined. Therapeutic interchange programs existed only in two of these countries. The mean number of committee members ranged between six and eight. More than 89% of the committees included a pharmacist. Standard operating procedures were implemented by 89% of the committees. The most influential factors in the decision-making were clinical trial results or drug costs rather than pharmacoeconomic studies. Other local organization-dependent factors were also important., Conclusions: The structure and operating procedures of Hospital Pharmacy and Therapeutics Committees are similar in select Western countries. Information from clinical trials is the most influential factor in the decision-making process.

Objective: To analyse the assessment reports published on the GENESIS webpage (Group for Innovation, Assessment, Standardisation and Research in the Selection of Drugs) and assess the variability of the group's proposals to include drugs in the Formulary., Method: We analysed reports published by hospitals on the GENESIS webpage between 2004 and 2007. Data were collected on drugs and indications, ATC group, open or restricted access publications, hospital, and publication date. We drafted a questionnaire that would measure to what extent to what extent the 9-section model recommended by GENESIS was included in each report. For drugs with two or more reports, we analysed whether the recommendation coincided and the possible cause in the event of conflict., Results: We analysed 416 reports corresponding to 185 different drug indications. 93% included 6 or more of the recommended sections, a number which increased over time. The most frequently included sections were: approved indications (92%), mechanism of action (95%), and references (86%) (percentages from 2007). Sections which had an increasing but lower percentage were: differential characteristics (60%), literature search method (40%) and conclusions with a summary of efficacy, safety and cost data (52%). 73% of which had definite recommendations, which coincided for 42 out of the 67 drugs with more than one recommendation report., Conclusions: The work carried out by the GENESIS group has enabled Spanish hospitals to share their drug assessment reports and making them more complete, although there are still some aspects that can be improved., (Copyright © 2010 SEFH.

Objective: To assess the impact of pharmaceutical intervention on the use of sequential therapy (ST) with fluoroquinolones., Methods: A prospective comparative study of pharmaceutical intervention in two stages: observational stage and intervention stage for ST promotion., Results: In all, 250 patients receiving intravenous therapy with fluoroquinolones (113 with levofloxacin and 137 with ciprofloxacin) were studied, with 76 and 70 patients, respectively, being eligible for a pharmaceutical intervention program to promote ST. Pharmaceutical intervention showed a decreased duration of intravenous therapy and increased duration of oral therapy for both drugs, as well as decreased medication-related costs, all in a statistically significant manner., Discussion: ST promotion provides an opportunity to expand the role of hospital pharmacists and to optimize fluoroquinolone-based therapy, which results in decreased intravenous treatments and provides a more cost-effective option.
