Public health impact of statin prescribing strategies based on JUPITER Modeling study from a population-based study.

OBJECTIVE: To evaluate the public health impact of statin prescribing strategies based on the Justification for the Use of Statins in Primary Prevention: An Intervention Trial Evaluating Rosuvastatin Study (JUPITER). METHODS: We studied 2268 adults aged 35-75 without cardiovascular disease in a population-based study in Switzerland in 2003-2006. We assessed the eligibility for statins according to the Adult Treatment Panel III (ATPIII) guidelines, and by adding "strict" (hs-CRP≥2.0mg/L and LDL-cholesterol <3.4mmol/L), and "extended" (hs-CRP≥2.0mg/L alone) JUPITER-like criteria. We estimated the proportion of CHD deaths potentially prevented over 10years in the Swiss population. RESULTS: Fifteen % were already taking statins, 42% were eligible by ATPIII guidelines, 53% by adding "strict", and 62% by adding "extended" criteria, with a total of 19% newly eligible. The number needed to treat with statins to avoid one CHD death over 10years was 38 for ATPIII, 84 for "strict" and 92 for "extended" JUPITER-like criteria. ATPIII would prevent 17% of CHD deaths, compared with 20% for ATPIII+"strict" and 23% for ATPIII + "extended" criteria (+6%). CONCLUSION: Implementing JUPITER-like strategies would make statin prescribing for primary prevention more common and less efficient than it is with current guidelines.

Topiramate in opiate withdrawal- comparison with clonidine and with carbamazepine/mianserin

There are some rationales for developing anticonvulsants for the treatment of substance abuse. The blockade of the AMPA/kainate subtype of glutamate receptor by topiramate may be of particular interest, as preclinical studies of withdrawal from opioids suggest that whilst AMPA-receptor antagonists may not be able to prevent tolerance or dependence from developing, they may ameliorate both physical and emotional consequences of withdrawal. Methods. Ten consecutively admitted patients treated with topiramate were compared in a retrospective naturalistic drug utilization observation study with 10 consecutively admitted patients treated with clonidine and with 10 consecutively admitted patients treated with a carbamazepine/ mianserin combination. Results. In 9 cases of the clonidine group and in 7 carbamazepine/mianserin treated patients the dose had been reduced, whereas this occurred in only 2 topiramate treated patients (p < 0.01). Patients in the topiramate group received less p.r.n. myorelaxant medication than the two other groups, and there was a significant difference between the three groups with regard to p.r.n. analgesics (p < 0.05), topiramate and clonidine treated patients receiving fewer analgesics than the carbamazepine/mianserin group. Conclusions. Compared to clonidine and carbamazepine/mianserin, a detoxification scheme using high initial and then decreasing doses of topiramate appeared to be appropriate for most patients and as associated with less analgesic and myorelaxant comedication, indicating a more promising efficacy at the used doses

Antipsychotic polypharmacy in a regional health service: a population-based study

Background To analyse the extent and profile of outpatient regular dispensation of antipsychotics, both in combination and monotherapy, in the Barcelona Health Region (Spain), focusing on the use of clozapine and long-acting injections (LAI). Methods Antipsychotic drugs dispensed for people older than 18 and processed by the Catalan Health Service during 2007 were retrospectively reviewed. First and second generation antipsychotic drugs (FGA and SGA) from the Anatomical Therapeutic Chemical classification (ATC) code N05A (except lithium) were included. A patient selection algorithm was designed to identify prescriptions regularly dispensed. Variables included were age, gender, antipsychotic type, route of administration and number of packages dispensed. Results A total of 117,811 patients were given any antipsychotic, of whom 71,004 regularly received such drugs. Among the latter, 9,855 (13.9%) corresponded to an antipsychotic combination, 47,386 (66.7%) to monotherapy and 13,763 (19.4%) to unspecified combinations. Of the patients given antipsychotics in association, 58% were men. Olanzapine (37.1%) and oral risperidone (36.4%) were the most common dispensations. Analysis of the patients dispensed two antipsychotics (57.8%) revealed 198 different combinations, the most frequent being the association of FGA and SGA (62.0%). Clozapine was dispensed to 2.3% of patients. Of those who were receiving antipsychotics in combination, 6.6% were given clozapine, being clozapine plus amisulpride the most frequent association (22.8%). A total of 3.800 patients (5.4%) were given LAI antipsychotics, and 2.662 of these (70.1%) were in combination. Risperidone was the most widely used LAI. Conclusions The scant evidence available regarding the efficacy of combining different antipsychotics contrasts with the high number and variety of combinations prescribed to outpatients, as well as with the limited use of clozapine.

Etude descriptive des médicaments non utilisés collectés dans une officine française de la Région Centre

[...] Cette étude a permis d'évaluer ce que représente le coût des MNU [médicaments non utilisés] à l'officine sur une période donnée. Les résultats ont traduit un gaspdlage certain des ressources de santé. La fin du recyclage humanitaire des médicaments étant décidé par les autorités publiques depuis le 11 janvier 2007, la collecte des MNU à l'officine garde un intérêt dans la protection de l'environnement et la prévention des accidents domestiques. Mais les pharmaciens pourraient participer à la prévention de ces gaspillages par un renforcement des mesures d'informations sur le bon usage des médicaments et par une attention particulière donnée au monitoring et au soutien de l'adhésion thérapeutique des patients ('programmes de soins pharmaceutiques).[Auteure, p. 4]

Évolution de la gestion pharmacologique de la polyarthrite rhumatoïde et impact sur le risque de fracture ostéoporotique non vertébrale

Au cours des dernières années, le développement des connaissances au niveau de l’étiologie de la maladie ainsi que l’arrivée de nouveaux médicaments et de lignes directrices guidant la pratique clinique sont susceptibles d’avoir entraîné une meilleure gestion de la polyarthrite rhumatoïde (PAR) et de l’ostéoporose, une comorbidité fréquente chez ces patients. Dans cette thèse, trois questions de recherche sont étudiées à l’aide des banques de données administratives québécoises (RAMQ, MED-ÉCHO). Une première étude documente l’utilisation des médicaments pour la PAR au Québec. À ce jour, il s’agit de la seule étude canadienne à rapporter les tendances d’utilisation des DMARD (disease-modifying antirheumatic drug) biologiques depuis leur introduction dans la pratique clinique. Au cours de la période à l’étude (2002-2008), l’utilisation de DMARD (synthétiques et biologiques) a augmenté légèrement dans la population atteinte de PAR (1,9%, 95% CI : 1,1 - 2,8). Cependant, malgré la présence de recommandations cliniques soulignant l’importance de commencer un traitement rapidement, et la couverture de ces traitements par le régime général d’assurance médicaments, les résultats démontrent une initiation sous-optimale des DMARD chez les patients nouvellement diagnostiqués (probabilité d’initiation à 12 mois : 38,5%). L’initiation de DMARD était beaucoup plus fréquente lorsqu’un rhumatologue était impliqué dans la provision des soins (OR : 4,31, 95% CI : 3,73 - 4,97). Concernant les DMARD biologiques, le facteur le plus fortement associé avec leur initiation était l’année calendrier. Chez les sujets diagnostiqués en 2002, 1,2 sur 1 000 ont initié un DMARD biologique moins d’un an après leur diagnostic. Pour ceux qui ont été diagnostiqués en 2007, le taux était de 13 sur 1 000. Les résultats démontrent que si la gestion pharmacologique de la PAR s’est améliorée au cours de la période à l’étude, elle demeure tout de même sous-optimale. Assurer un meilleur accès aux rhumatologues pourrait, semble-t-il, être une stratégie efficace pour améliorer la qualité des soins chez les patients atteints de PAR. Dans une deuxième étude, l’association entre l’utilisation des DMARD biologiques et le risque de fractures ostéoporotiques non vertébrales chez des patients PAR âgés de 50 ans et plus a été rapportée. Puisque l’inflammation chronique résultant de la PAR interfère avec le remodelage osseux et que les DMARD biologiques, en plus de leur effet anti-inflammatoire et immunosuppresseur, sont des modulateurs de l’activité cellulaire des ostéoclastes et des ostéoblastes pouvant possiblement mener à la prévention des pertes de densité minérale osseuse (DMO), il était attendu que leur utilisation réduirait le risque de fracture. Une étude de cas-témoin intra-cohorte a été conduite. Bien qu’aucune réduction du risque de fracture suivant l’utilisation de DMARD biologiques n’ait pu être démontrée (OR : 1,03, 95% CI : 0,42 - 2,53), l’étude établit le taux d’incidence de fractures ostéoporotiques non vertébrales dans une population canadienne atteinte de PAR (11/1 000 personnes - années) et souligne le rôle d’importants facteurs de risque. La prévalence élevée de l’ostéoporose dans la population atteinte de PAR justifie que l’on accorde plus d’attention à la prévention des fractures. Finalement, une troisième étude explore l’impact de la dissémination massive, en 2002, des lignes directrices du traitement de l’ostéoporose au Canada sur la gestion pharmacologique de l’ostéoporose et sur les taux d’incidence de fractures ostéoporotiques non vertébrales chez une population de patients PAR âgés de 50 ans et plus entre 1998 et 2008. Étant donné la disponibilité des traitements efficaces pour l’ostéoporose depuis le milieu des années 1990 et l’évolution des lignes directrices de traitement, une réduction du taux de fractures était attendue. Quelques études canadiennes ont démontré une réduction des fractures suivant une utilisation étendue des médicaments contre l’ostéoporose et de l’ostéodensitométrie dans une population générale, mais aucune ne s’est attardée plus particulièrement sur une population adulte atteinte de PAR. Dans cette étude observationnelle utilisant une approche de série chronologique, aucune réduction du taux de fracture après 2002 (période suivant la dissémination des lignes directrices) n’a pu être démontrée. Cependant, l’utilisation des médicaments pour l’ostéoporose, le passage d’ostéodensitométrie, ainsi que la provision de soins pour l’ostéoporose en post-fracture ont augmenté. Cette étude démontre que malgré des années de disponibilité de traitements efficaces et d’investissement dans le développement et la promotion de lignes directrices de traitement, l’effet bénéfique au niveau de la réduction des fractures ne s’est toujours pas concrétisé dans la population atteinte de PAR, au cours de la période à l’étude. Ces travaux sont les premiers à examiner, à l’aide d’une banque de données administratives, des sujets atteints de PAR sur une période s’étalant sur 11 ans, permettant non seulement l’étude des changements de pratique clinique suivant l’apparition de nouveaux traitements ou bien de nouvelles lignes directrices, mais également de leur impact sur la santé. De plus, via l’étude des déterminants de traitement, les résultats offrent des pistes de solution afin de combler l’écart entre la pratique observée et les recommandations cliniques. Enfin, les résultats de ces études bonifient la littérature concernant la qualité des soins pharmacologiques chez les patients PAR et de la prévention des fractures.

Consumo de antibióticos de uso controlado en adultos mayores en una institución prestadora de servicios de salud de Bogotá

Introducción: producir conocimiento sobre el consumo de antibióticos es importante para fomentar el uso racional de medicamentos y controlar el crecimiento de la resistencia bacteriana, sin afectar el tratamiento de infecciones, especialmente en adultos mayores. Metodología: estudio de Utilización de Medicamentos (antibióticos de uso controlado) en adultos mayores en una IPS en Bogotá, basado en registros de facturación y prescripción entre enero y julio de 2009. Resultados: la mediana de edad estuvo en 75 años; 48,6% eran mujeres; los registros del grupo de 71–80 años mostraron una alta frecuencia de prescripción de antibióticos. De los 4624 registros de egresos, 426 tenían al menos una solicitud de prescripción de algún antibiótico de uso controlado. De las 676 solicitudes de prescripción de antibióticos de uso controlado, 27,7% correspondieron al principio activo Vancomicina. Se consumieron en total 5983 DDD de antibióticos de uso controlado; la densidad de consumo fue 18,63 DDD/100 camas-día y Meropenem el antibiótico de mayor consumo con 4,59 DDD/100 camas-día, correspondiente a 24,6% del total de DDD/100 camas-día. Los antibióticos controlados representaron US$361.062 del total facturado en medicamentos. Meropenem tiene el costo total más alto: US$136.313. El antibiótico con mayor costo por DDD fue Tigeciclina con US$27.346. Conclusiones: la frecuencia de prescripción de antibióticos de uso controlado fue 9,2% con mayor prescripción en el grupo de 71- 80 años. 59,2% de las solicitudes de prescripción correspondieron a un antibiótico. Vancomicina fue el antibiótico más prescrito. Se utilizaron 18,63 DDD/100 camas-día en total de antibióticos de uso controlado. Meropenem, Piperacilina/Tazobactam y Ertapenem representaron el 75% del costo total facturado de antibióticos de uso controlado. De los 16 antibióticos estudiados, seis fueron prescritos en mayor porcentaje en otras septicemias.

Automedicação e guarda de medicamentos por universitários das áreas de saúde e tecnologia

This study aimed to compare self-medication and domestic drug storage among undergraduate students in the areas of health and technology. This is a descriptive study of cross-sectional type and quantitative approach, conducted in a Public University of Natal, Rio Grande do Norte, Brazil. The sample consisted of 300 students of the third year of undergraduate courses at the Center for Health Sciences and Technology Center, selected through a simple random sample. The project was authorized by the Ethics Committee of Federal University of Rio Grande do Norte (CAAE 0137.0.051.000-10). Data collection lasted twelve months and was conducted during the period of study participants, in the university environment. The instrument for data collection was a structured questionnaire consisting of open and closed questions. For data analysis, we used descriptive statistics and applied Fisher s exact test and Chi-square test with adopted level of significance α=5% and 10%. For the variables that correlated with self-medication (p<0.05), we subsequently calculated the odds ratios and confidence intervals. The prevalence of undergraduate students who performed self-medication in the 15 days prior to the collection accounted for 33.7% and, by analyzing each knowledge area, we verified was a higher prevalence of self-medication among students in the technological area (37.3%). The analysis of the socio-demographic characteristics of the participants in this practice revealed a significant difference between the knowledge areas in the income and self-medication variables (p=0.005). General analgesics and antipyretics (N02) represent the therapy group most used in self-medication (57.4%), especially acetaminophen (28.7%), and the main health situations that motivated this practice related to pain, especially headaches (48.5%). Regarding the indication of the drugs used, the majority of students self-medicated themselves on their own (71.3%). As regards to the in-home drug storage, most of the participants had a home pharmacy (88%). By analyzing the socioeconomic characteristics, the variables medical service and home medicine presented a significant difference (p=0.002). General 10 analgesics and antipyretics constituted the medicinal products most found in the home pharmacies, especially acetaminophen. The main room used for the drug storage was the kitchen (36.4%), most students kept these products in boxes of different materials (38.6%) and the medicines stored at home of most of the participants were not easily accessible to children (75%). The results reinforce the need to develop strategies, from the reality found, aiming to encourage and implement educational and preventive activities with undergraduate students on the importance of proper self-medication and in-home drug storage. Despite the sample in our study is relatively small, not representative for the whole country, we believe that, at national level, the panorama of the subject does not present major differences

Estoque doméstico e uso de medicamentos em uma população cadastrada na estratégia saúde da família no Brasil

Objective. To identify families served by the family health strategy (FHS) storing medicines at home, to evaluate storage conditions, and to investigate medicine use practices.Methods. The study was conducted in a municipality in the state of São Paulo with two FHS units serving 1 867 households. The sample was selected by means of stratified random sampling. Data collection was conducted through semistructured interviews from July to October 2008.Results. One resident was interviewed in each of the 280 households visited. Medicines were found in 255 households (91.1%). of 326 storage locations, 217 (75.8%) were inadequate (easily accessible to children or exposed to moisture, light). of the 2 578 medicines identified, 2 059 medicines (79.9%) in 236 (84.3%) households had safety or identification problems. of the 280 respondents, 179 (63.9%) used medications. of these, 24 were self-medicating, only one with an over-the-counter drug. Only 44 users had the prescription for their medication, and 21 did not follow the prescription in terms of dosage or had interrupted the treatment.Conclusions. Non-adherence to recommended treatment can lead to negative outcomes, such as inefficiency (using dosages lower than prescribed), poisoning (using dosages higher than prescribed), and other adverse reactions.

Consumo de medicamentos em região do Estado de São Paulo (Brasil), 1985

Com o objetivo de avaliar as características do consumo de medicamentos na população urbana de Araraquara, SP, Brasil, foram coletados dados, por meio de entrevistas domiciliares, de uma amostra da população que consumiu pelo menos um medicamento nos quinze dias que antecederam a data da entrevista. O estudo foi realizado no período de agosto a setembro de 1985. Verificou-se que 42,1% dos medicamentos utilizados foram adquiridos sem prescrição médica. O consumo entre o sexo feminino foi maior que para o sexo masculino. Na automedicação o grupo que apresentou taxa mais elevada, segundo a faixa etária, foi o de 50 anos e mais, com 31,6%. Grande parte do consumo de medicamentos constituiu-se dos industrializados (97,6%). As prescrições médicas, feitas em consultas anteriores, e avalia das como bem sucedidas foram retomadas em situações diversas (12,0%), revelando o importante papel que o médico desempenha na formação dos critérios de escolha dos remédios utilizados nas práticas de automedicação. O farmacêutico e/ou balconista de farmácia contribui com 10,0% dos medicamentos usados que tiveram essa via de indicação. As orientações feitas por amigos, vizinhos e parentes (9,1%) revelaram intenso circuito de trocas de socializações quanto aos quadros móbidos e indicações terapêuticas.

Uso de medicamentos por pessoas com deficiências em áreas do estado de São Paulo

OBJETIVO: Analisar o consumo de medicamentos e os principais grupos terapêuticos consumidos por pessoas com deficiências físicas, auditivas ou visuais. MÉTODOS: Estudo transversal em que foram analisados dados do Inquérito Multicêntrico de Saúde no Estado de São Paulo (ISA-SP) em 2002 e do Inquérito de Saúde no Município de São Paulo (ISA-Capital), realizado em 2003. Os entrevistados que referiram deficiências foram estudados segundo as variáveis que compõem o banco de dados: área, sexo, renda, faixa etária, raça, consumo de medicamentos e tipos de medicamentos consumidos. RESULTADOS: A percentagem de consumo entre as pessoas com deficiência foi de: 62,8% entre os visuais; 60,2% entre os auditivos e 70,1% entre os físicos. As pessoas com deficiência física consumiram 20% mais medicamentos que os não-deficientes. Entre as pessoas com deficiência visual, os medicamentos mais consumidos foram os diuréticos, agentes do sistema renina-angiotensina e analgésicos. Pessoas com deficiência auditiva utilizaram mais analgésicos e agentes do sistema renina-angiotensina. Entre indivíduos com deficiência física, analgésicos, antitrombóticos e agentes do sistema renina-angiotensina foram os medicamentos mais consumidos. CONCLUSÕES: Houve maior consumo de medicamentos entre as pessoas com deficiências quando comparados com os não-deficientes, sendo os indivíduos com deficiência física os que mais consumiram fármacos, seguidos de deficientes visuais e auditivos.

Utilização de medicamentos e fatores associados: um estudo de base populacional no Município de Campinas, São Paulo, Brasil

Este artigo analisa a prevalência da utilização de medicamentos segundo variáveis demográficas, socioeconômicas e de comportamentos relacionados à saúde, identificando fatores associados ao uso por meio de estudo transversal de base populacional, com 941 pessoas de 18 anos ou mais residentes em Campinas, São Paulo, Brasil. A amostragem foi realizada em múltiplos estágios, estratificada e por conglomerados. Utilizou-se o teste qui-quadrado, foram estimadas as razões de prevalência ajustadas por sexo e idade e os respectivos IC95%. Desenvolveu-se modelo de regressão múltipla de Poisson ficando associados ao uso: sexo feminino, idade de 40 anos e mais, morbidade referida nos últimos 15 dias e número de doenças crônicas. Os medicamentos mais consumidos foram para os sistemas cardiovascular e nervoso, e os fitoterápicos. A prevalência de uso de medicamentos em Campinas encontrou-se inferior à maioria dos estudos. Por meio de inquéritos de saúde locais espera-se conhecer o perfil de uso dos medicamentos pela população e garantir intervenções mais direcionadas para a Política de Assistência Farmacêutica.

Using Mastitis Records and Somatic Cell Count Data

On-farm records are essential for managing mastitis in dairy herds. Mastitis records are a useful tool for caring for an individual cow, to monitor compliance of farm personnel working with groups of animals, to understand the epidemiology of mastitis in the herd, to ensure responsible drug utilization, and to document accountability in care of the cow. Herds have become larger and more people are involved with individual animal care. This article describes a records plan that can be used to monitor mastitis at the herd level, aid in decision-making processes for individual cows, and improve drug use on dairy herds.
