ABSTRACT
OBJECTIVE: To examine whether the use of a monthly electronic medication organizer device equipped with an alarm clock, called Electronic System for Personal and Controlled Use of Medications (Supermed), improves medication adherence of older adults with hypertension. METHODS: This is a quali-quantitative, prospective, before-and-after study performed with 32 older adult patients with diagnosis of hypertension, who were recruited at a Primary Care Unit in Brazil. RESULTS: The main outcome measures were improvement of medication adherence and blood pressure control after intervention with Supermed. Regarding medication adherence, 81.2% of patients were "less adherent" in the pre-intervention period, and 96.9% were "more adherent" in the post-intervention period. This means that 78.1% of patients changed from "less adherent" to "more adherent" after the intervention with Supermed (p<0.001). The mean systolic and diastolic blood pressure differences between intervention day and post-intervention were 18.5mmHg (p<0.0001) and 4.3mmHg (p<0.007), respectively, and the differences between mean systolic and diastolic blood pressure between pre-intervention and post-intervention were 21.6mmHg (p<0.001) and 4.7mmHg (p<0.001) respectively. CONCLUSION: The use of Supermed significantly improved self-reported medication adherence and blood pressure control in a hypertensive older adult population.

RESUMO Objetivo: Avaliar se o uso de um dispositivo organizador de medicamentos eletrônico, mensal, equipado com um despertador, chamado Sistema Eletrônico para Uso Personalizado e Controlado de Medicamentos (Supermed), melhora a adesão à medicação de idosos com hipertensão. Métodos: Trata-se de um estudo qualiquantitativo, prospectivo, antes e depois, realizado com 32 pacientes idosos, com diagnóstico de hipertensão, recrutados em uma Unidade Básica de Saúde do Brasil. Resultados: Os principais desfechos foram a melhor adesão à medicação e o controle da pressão arterial após a intervenção com Supermed. Quanto à adesão medicamentosa, 81,2% dos pacientes eram "menos aderentes" no período pré-intervenção, e 96,9% eram "mais aderentes" no período pós-intervenção. Isso significa que 78,1% dos pacientes mudaram de "menos aderentes" para "mais aderentes" após a intervenção com Supermed (p<0,001). As diferenças da pressão arterial sistólica e diastólica média entre o dia da intervenção e pós-intervenção foram 18,5mmHg (p<0,0001) e 4,3mmHg (p<0,007), respectivamente, e as diferenças entre as médias da pressões arteriais sistólica e diastólica entre os períodos pré-intervenção e pós-intervenção foram de 21,6mmHg (p<0,001) e 4,7mmHg (p<0,001), respectivamente. Conclusão: O uso de Supermed melhorou de forma significativa a adesão medicamentosa e o controle da pressão arterial em uma população idosa hipertensa.

This article describes the development of an electronic prototype to organize medications - the Electronic System for Personal and Controlled Use of Medications (Sistema Eletrônico de Uso Personalizado e Controlado de Medicamentos, SUPERMED). The prototype includes a drawer containing 1 month's supply of medicines, sound and visual medication timers, and a memory card for recording the times when the box was opened/closed (scheduled and unscheduled). This information is later transferred to a computer. Evolutionary prototyping was used to develop SUPERMED with the Arduino platform and C programming. To read alarm and box opening/closing data, software was developed in Java. Once the alarms are programmed (ideally by a health care professional), no additional adjustments are required by the patient. The prototype was tested during 31 days by the developers, with satisfactory functioning. The system seems adequate to organize medications and facilitate adherence to treatment. New studies will be carried out to validate and improve the prototype.

O presente artigo descreve o desenvolvimento de um protótipo eletrônico para organizar medicamentos, denominado Sistema Eletrônico de Uso Personalizado e Controlado de Medicamentos (SUPERMED). O protótipo inclui uma gaveta que contém os medicamentos a serem utilizados durante 1 mês, alarme sonoro e visual programado para disparar nos horários de administração dos medicamentos e registro dos horários em que a caixa foi aberta (horário previsto ou fora do horário previsto) gravado em cartão de memória e posteriormente transferido para leitura em computador. Para o desenvolvimento do protótipo, seguiu-se o modelo de prototipação evolucionária. O SUPERMED foi projetado sobre a plataforma Arduino e a programação foi desenvolvida em linguagem C. Para leitura do sistema de alertas e registro dos horários de abertura da caixa, desenvolveu-se um software em linguagem Java. Uma vez feita a programação dos alarmes (idealmente por um profissional da área de saúde), não há nenhum ajuste adicional a ser feito pelo paciente. As funcionalidades do protótipo foram testadas durante 31 dias pelos pesquisadores, com funcionamento bem-sucedido. O sistema parece adequado para organizar os medicamentos e facilitar a adesão medicamentosa. Novos estudos serão realizados para validar a aperfeiçoar o protótipo.
