This study aimed to identify variables associated with the appropriate recall of indications and the drug classes that represented the most unmatching medications (i.e., when the individual who used it had not reported any illness that matched its indications). Community-dwelling individuals aged ≥60 years using ≥1 medication, from Santa Cruz da Esperança-SP, Brazil, were home-interviewed. Logistic regression models were used to evaluate the association between the appropriate recall of the indications for all medications in use and the following: gender, age, education, individual income, living arrangement, self-perceived health, and medication number, administration, payment, and identification. Medications whose indications were inappropriately recalled were classified as matching or unmatching. One hundred seventeen individuals used an average of 5.1 (standard deviation, 3.3) medications. Sixty-one (52.1%) appropriately recalled all indications. The appropriate recall of all indications was negatively associated with the number of medications in use (e.g., individuals taking 5-6 medications were 25 times less likely to appropriately recall all indications than those taking 1-2). Antithrombotic, acid-related disorder and psychoanaleptic classes showed greater frequencies of unmatching than matching medications. Therefore, counseling the elderly about drug indications should focus on those using ≥3 medications and/or antithrombotic, acid-related disorder, and psychoanaleptic agents.

Resumo Objetivo Identificar preditores do conhecimento inadequado sobre medicamentos prescritos a pacientes ambulatoriais muito idosos e seus cuidadores. Método O conhecimento sobre os medicamentos prescritos para 80 pacientes com 80 anos ou mais de idade foi avaliado por meio de um questionário validado, em uma entrevista realizada com os pacientes ou seus cuidadores (quando os pacientes apresentavam dificuldades de comunicação, demência ou qualquer necessidade de assistência para ajudá-los a usar medicamentos). Dois modelos de regressão logística hierárquica avaliaram a associação entre conhecimento inadequado sobre medicamentos e variáveis sociodemográficas e medicamentosas. Resultados Trinta e nove (48,8%) entrevistados eram cuidadores. Conhecimento inadequado foi encontrado em 81,5% (404/496) dos medicamentos prescritos. Forma de administração, Dose, Frequência e Duração do Tratamento foram os aspectos de maior conhecimento, enquanto Reações Adversas, Precauções, Interações e Contraindicações, os de menor. No primeiro modelo, o conhecimento inadequado foi associado à escolaridade do ensino fundamental completo ao médio incompleto (Razão de Chances (RC):0,12; p=0,018), do médio ao superior incompleto (RC:0,12; p<0,001), superior completo (RC:0,13; p<0,001), agentes que atuam no sistema renina-angiotensina (SRA) (RC:0,30; p=0,001), diuréticos (RC:0,31; p=0,013) e antitrombóticos (RC:12,59; p=0,027). No segundo modelo, os preditores foram cuidadores (RC:0,17; p<0,001), agentes que atuam no SRA (RC:0,33; p=0,002), diuréticos (RC:0,35; p=0,024) e antitrombóticos (RC:12,57; p=0,026). Conclusão A maioria dos medicamentos prescritos para pessoas muito idosas é pouco conhecida. Além disso, o aconselhamento acerca de informações sobre medicamentos deve ser mais intensivo para os pacientes do que para seus cuidadores, com foco em informações de segurança e ser direcionado a antitrombóticos.

Abstract Objective Identify predictors of inadequate knowledge about the medication prescribed to very old outpatients and their caregivers. Method The knowledge on the medication prescribed for 80 patients aged 80 years and over was assessed using a validated questionnaire to interview patients or their caregivers (when patients had communication difficulties, dementia, or any need for care to help them take the medication). Two hierarchical logistic regression models assessed the association between inadequate knowledge of the medication and sociodemographic and drug variables. Results Thirty-nine (48.8%) respondents were caregivers. Inadequate knowledge was found in 81.5% (404/496) of medication prescribed. Route of Administration, Dose, Frequency, and Duration of Treatment were the aspects of greatest knowledge, whereas Adverse Effects, Precautions, Interactions, and Contraindications were the least known ones. In the first model, inadequate knowledge was associated to the level of education from complete elementary school to incomplete high school (Odds Ratio (OR): 0.12; p=0.018), from high school to incomplete higher education (OR: 0.12; p<0.001), complete higher education (OR: 0.13; p<0.001), agents acting on the renin-angiotensin system (RAS) (OR: 0.30; p=0.001), diuretics (OR: 0.31; p=0.013) and antithrombotic (OR: 12.59; p=0.027). In the second model, the predictors were caregivers (OR: 0.17; p<0.001), agents working in the RAS (OR: 0.33; p=0.002), diuretics (OR: 0.35; p=0.024) and antithrombotic (OR: 12.57; p=0.026). Conclusion Most of the medication prescribed for very old people is not very well known. Also, advice on drug information should be more intensive to patients than to their caregivers, with a focus on safety information and targeted at antithrombotics.

Resumo Este trabalho adaptou transculturalmente o questionário espanhol “Conocimiento del Paciente sobre sus Medicamentos” (CPM-ES-ES) para uso no Brasil. Ele mede o grau de conhecimento sobre medicamentos por meio de 11 perguntas. Oitenta pacientes ≥ 80 anos foram investigados e com 39 também foi entrevistado o cuidador. A avaliação das equivalências conceitual e de item considerou o conceito de conhecimento e as perguntas que o medem como pertinentes. A equivalência semântica foi obtida pela correspondência de significado denotativo e conotativo dos itens. O estudo da equivalência de mensuração incluiu análise fatorial e o cálculo de estimativas de validade e confiabilidade. Semelhante ao questionário original, a análise de componentes principais identificou 4 componentes, porém, em 2 deles houve diferenças nos itens incluídos. Uma pergunta foi removida desta análise devido à sua inadequação amostral. O conhecimento sobre medicamentos esteve correlacionado à complexidade da prescrição r = -0,22, p = 0,046. O conhecimento sobre anti-hipertensivos esteve correlacionado à sua adesão r = 0,70, p < 0,001, e ao controle da pressão arterial rb = 0,46, p = 0,029. A versão adaptada apresentou equivalência funcional de modo que pode ser usada no contexto brasileiro.

Abstract This work cross-culturally adapted the Spanish questionnaire `Patients’ knowledge about their medications (“Conocimiento del Paciente sobre sus Medicamentos” - CPM-ES-ES) for use in Brazil. It measures the level of medication knowledge by means of 11 questions. Eighty patients ≥ 80 years were investigated and in 39 cases the caregivers were interviewed. The evaluation of conceptual and item equivalences considered the concept of knowledge and the questions that assess it as pertinent. Semantic equivalence was obtained by the correspondence in the denotative and connotative meaning of items. The study of measurement equivalence included factorial analysis and the calculation of validity and reliability estimates. As with the original questionnaire, principal component analysis identified 4 components, however, in 2 of them there were differences regarding included items. One question was removed from this analysis due to its sample inadequacy. Medication knowledge was correlated with medication regimen complexity r = -.22, p = .046. Medication knowledge of antihypertensives was correlated with their adherence r = .70, p < .001, and blood pressure control rb = .46, p = .029. The adapted version revealed functional equivalence, therefore it can be used in the Brazilian context.

Objectives: To uncover reasons why patients missed pharmaceutical care (PC) appointments, identify predictive factors to miss at least one appointment and to reschedule after a miss, and compare the rescheduling behavior of patients receiving different types of PC. Methods: All elderly patients who had at least one scheduled appointment in the PC service of a health setting of São Paulo city, Brazil, from January to December/2011 were included. Chi-square analysis compared categorical data between groups; multivariate logistic regression models predicted attendance and rescheduling behavior. Results: We identified 421 patients, being 221 (52.5%) non-attenders. Forgetting the appointment was the most common patient-related reason (56.3%). Illiteracy was a risk factor to be a non-attender [OR(95%CI)=2.27(1.17:4.40), p=0.015]. Patients having previous knowledge of the pharmacist presented more chance to rescheduled an appointment after the first miss compared to those who had not [OR(95%CI)=3.57(1.90:6.71), p<0.001]. Further, non-attenders who had knowledge of the pharmacist and received Medication Review with Follow-up rescheduled more than the ones receiving other types of PC (p=0.035). Conclusion: Illiteracy predicted non-attendance in PC to aged outpatients and forgetfulness was the main reason for that. The previous acquaintance of the pharmacist and the provision of pharmaceotherapeutic follow-up explained the rescheduling behavior, which indicates the establishment of a patient-centered patient-pharmacist relationship plays a pivotal role in the continuity of the PC.

Objetivos: Descubrir razones por las que los pacientes perdieron la cita en atención farmacéutica (AF), identificar los factores predictivos de perder al menos una cita y reprogramar después de una ausencia, y comparar el comportamiento de reprogramación de los pacientes recibiendo diferentes tipos de AF. Métodos: Se incluyeron todos los pacientes mayores que tenían al menos una cita programada en el servicio de AF de un establecimiento de salud de la ciudad de São Paulo, Brasil, de enero a diciembre/2011. Análisis chi-cuadrado comparó datos categóricos entre los grupos; modelos de regresión logística multivariante predijeron el comportamiento de presencia y de reprogramación. Resultados: Se identificaron 421 pacientes, siendo 221 (52,5%) ausentes. El olvido fue el motivo relacionado con el paciente más frecuente (56,3%). El analfabetismo fue un factor de riesgo para ser un ausente [OR (IC95%)=2,27(1,17:4,40), p=0,015]. Los pacientes que tenían conocimiento previo del farmacéutico presentaron más chance de reprogramar una cita después de la primera ausencia en comparación con los que no tenía [OR (IC95%)=3,57(1,90:6,71), p<0,001]. Además, ausentes que tenían conocimiento del farmacéutico y recibieron seguimiento farmacoterapéutico reprogramaron más de los que reciben otros tipos de PC (p=0,035). Conclusión: El analfabetismo predijo ausencia en pacientes ambulatorios mayores bajo PC y el olvido fue la principal razón para eso. El conocimiento previo del farmacéutico y la provisión del seguimiento farmacoterapéutico explicaron el comportamiento de reprogramación, lo que indica que el establecimiento de una relación con el farmacéutico centrada en el paciente juega un papel fundamental en la continuidad de la AF.
