Exposure to potentially inappropriate medications in Brazilian elderly outpatients with metabolic diseases

ABSTRACT Management of pharmacotherapy in elderly with metabolic diseases is challenging and potentially inappropriate medications (PIMs) are risk factors for drug interactions and adverse events. The exposure to PIMs in elderly outpatients with metabolic diseases and its relationship with polypharmacy and other variables was investigated. PIMs prescribed to 207 elderly patients (aged 60 to 96 years) with metabolic diseases who attended a University Hospital of Sao Paulo city, Brazil, from April/2010 to January/2011, were evaluated. PIMs were detected using both 2003 Beers and 2008 STOPP criteria. The association between PIMs and age, gender and polypharmacy was also examined. 2008 STOPP criteria detected more PIMs (44.4 %) than 2003 Beers criteria (16.0%, p<0.001). Beers detected mainly PIMs antihypertensive (clonidine, 20.0%; doxazosin, 10.0%) and antidepressant (fluoxetine, 15.0%; amitriptyline, 10.0%) PIMs. Medicines used for cardiovascular (aspirin, 53.7%) and endocrine system (glibenclamide, 21.3%) were PIMs more frequently detected by 2008 STOPP. Unlike age and gender, polypharmacy increased the risk of PIMs by both 2003 Beers (OR: 4.0, CI95%: 1.2-13.8, p<0.031) and 2008 STOPP (OR: 6.8, CI95%: 3.0-15.3, p<0.001). Beers and STOPP criteria are important tools to evaluate the exposure to PIMs, which is strongly associated with polypharmacy in elderly outpatients with metabolic diseases.

Pharmaceutic guidance to hypertensive patients at USP University Hospital: effect on adherence to treatment

This study was carried out in the outpatient unit of the Teaching Hospital of the University of São Paulo (USP), and studied the impact of an educational program aimed at improving hypertensive patients' compliance to treatment. Seventy five (75) hypertensive patients of both sexes took part in the study which had no age or race discrimination. Participants presented no other concomitant pathology, except obesity, diabetes and dyslipidemia. Forty one patients were allocated to an experimental group (EG). Experimental patients attended lectures on the use of medication and artery hypertension (AH) and received personal pharmaceutical guidance for nine months. The control group (CG) comprised 34 patients who did not attend lectures or receive pharmaceutical advice in this period. The results were assessed by means of serum levels of cholesterol and fractions of tryacylglicerol (TG), urine sodium and potassium, arterial pressure (AP), body mass index (BMI), waist-hip ratio (WHR), and also based on responses to a questionnaire focusing on AH and treatment. Patients who received the guidance showed a greater decrease in AP, TG and WHR, besides an increase of potassium excretion through urine. The experimental group also scored higher on the questionnaires compared to the CG. It was concluded that the educational process, applied under the conditions of the present study, improves clients' clinical response to antihypertensive treatment and should be included in therapeutic strategies of health care services dealing with hypertensive patients.

Este trabalho, realizado no ambulatório do Hospital Universitário da USP, estudou a repercussão de um programa educacional visando melhorar a adesão do paciente hipertenso ao tratamento. Participaram do trabalho 75 pacientes de ambos os sexos, sem discriminação de idade ou raça, sem outras patologias concomitantes, exceto obesidade, diabetes e dislipidemia. Quarenta e um pacientes assistiram palestras sobre uso de medicamentos e hipertensão arterial (HA), receberam orientação farmacêutica individualizada durante nove meses e foram denominados grupo experimental (GE); o grupo controle (GC), composto por 34 pacientes não assistiu palestras nem recebeu orientação farmacêutica, neste período. Os resultados foram avaliados por meio de níveis séricos de colesterol e frações, triacil-gliceróis (TG), sódio e potássio urinários, pressão arterial (PA), índice de massa corpórea (IMC), relação cintura/quadril (RCQ), além de respostas a questionário enfocando HA e tratamento. Verificou-se que os pacientes orientados apresentaram maior decréscimo da PA, TG e da RCQ, além de aumento da excreção urinária de potássio e do percentual de acertos em questionários, em relação ao GC. Concluiu-se que o processo educativo, utilizado nas condições deste estudo, melhora a resposta clínica do paciente ao tratamento anti-hipertensivo e deve fazer parte das estratégias terapêuticas de serviços de atendimento a pacientes hipertensos.

Orientação educacional do paciente hipertenso: efeito sobre a adesão ao tratamento / Educational guidance hypertension patient: effect on adhesion to medical treatment

A hipertensão arterial é uma doença crônica, caracterizada pelo aumento constante da pressão sangüínea acima da normalidade (140 mmHg para a sistólica e 90 mmHg para a diastólica). Tem alta prevalência, em geral assintomática e é determinada por diversos fatores como raça, hereditariedade, idade e hábitos de vida relacionados à alimentação e à prática de exercícios físicos. É um dos maiores fatores de risco de morbidade e mortalidade cardiovasculares no mundo todo, causando além dos sérios problemas relativos à saúde, alto custo social. A falta de adesão às recomendações que são dadas aos pacientes é uma das causas do insucesso no tratamento dos indivíduos hipertensos...
