ABSTRACT
PURPOSE: In the last decades, different criteria have been developed for detecting inappropriate prescription in older patients. In Spain, translations and adaptations of international lists are available but it would be necessary a national list which could cope with the peculiarities of our health system, existing pharmaceutical market, and prescription habits. We propose in this project the creation of a Spanish potentially inappropriate drugs list which could be applicable in our clinical scenario. METHODS: We use a Delphi method involving 25 experts from different backgrounds (Clinical Pharmacology, Geriatrics, Rational Use of Drugs and Pharmacy, Primary Care and Pharmacoepidemiology, and Pharmacovigilance) that were asked to participate in two-round questionnaires. For analysis, current recommendations of Worth and Pigni were applied, and every statement was classified into one of three groups: strong, moderate, or low agreement. Statements with strong agreement were accepted to be part of the inadequate prescription list. Moderate agreement statements were selected to enter the second questionnaire, and statements with low agreement were further analyzed to determine if it was due to heterogeneity or due to dispersion in the answers. RESULTS: The first questionnaire consisted of 160 proposed sentences, of which 106 reached a high agreement, 32 a moderate agreement, and 22 a low agreement. All sentences proposed in the second questionnaire reached a strong agreement. The total accepted sentences were 138. CONCLUSIONS: We offer a list of inadequate prescription in older patients adapted to the Spanish pharmacopeia and according to the prescription habits in our environment.

OBJECTIVE: Chronic exposure to non-persistent pesticides (NPPs) is of concern because these substances have been associated with chronic diseases. However, few studies have addressed chronic exposure to NPPs in Spanish populations. METHODS: We determined the presence of 24 pesticide residues by gas chromatography/mass spectrometry in 363 serum samples obtained from non-occupationally exposed adults from Tenerife island in 2007. RESULTS: Most of the samples (99.45%) showed detectable residues (6 ± 2 pesticides per sample). The most frequently detected pesticides were pyrethrins (96.1%), organophosphates (93.9%) and organochlorines (92.3%). The neurotoxicants bifenthrin and malathion were detected in 81% of the samples and hexachlorobenzene DDT and buprofezin in more than 50%. Malation, an "environmental obesogen", was detected in 82%, and "endocrine disrupter" pesticides were present in 97.2% of the samples. CONCLUSIONS: Because there is clear, continuous and inadvertent exposure to NPPs that may be inducing adverse effects on human health, NPPs should be included in biomonitoring studies.
