To investigate the prevalence of the adherence to the medications of the Specialized Component of Pharmaceutical Services and its association with regular access in users of these medications in the municipality of São Leopoldo, State of Rio Grande do Sul, Brazil.
This is a cross-sectional study with adults aged 20 years and over, who are users of medications of the Specialized Component of Pharmaceutical Services. Sampling was carried out consecutively for users who accessed the service of the Specialized Component of Pharmaceutical Services during the period from December 2014 to March 2015. Adherence was measured by the Brief Medication Questionnaire, and adherents were defined as those who did not present barriers to adherence in the three domains. Regular access was defined as getting all medications in the last three months, regardless of how it was obtained (paying or for free). Data analysis was performed using Poisson regression with robust variance.
We interviewed 414 subjects, being them mostly women (60.9%), with mean age of 55 years (SD = 13), and using a single medication of the Specialized Component of Pharmaceutical Services (68.1%). The prevalence of adherence to the medications used in the last seven days was 28.3% and the prevalence of free regular access was 46.1%, and 25.7% did not have access to all treatment. After adjusting for the number of medications in the Specialized Component of Pharmaceutical Services and the number of medications of continuous use, users who had free regular access in the last three months were 60% more likely to show adherence. For individuals with paid regular access, no association was found between access and adherence.
The regularity in the free access to the medications of the Specialized Component of Pharmaceutical Services has an impact on the behavior of users, contributing to their commitment to treatment and self-care. The Specialized Component of Pharmaceutical Services needs programming in order to avoid irregular access, which suggests a significant limitation of the drug policies in Brazil.
调查巴西南里奥格兰德州圣莱奥波尔多市药学服务专业组成部分药物治疗的依从性患病率及其与这些药物使用者定期获取药物的相关性。
这是一项针对20岁及以上成年人的横断面研究，这些成年人是药学服务专业组成部分药物的使用者。对2014年12月至2015年3月期间使用药学服务专业组成部分服务的使用者进行连续抽样。采用简明药物问卷测量依从性，依从者定义为在三个领域均未出现依从性障碍的人。定期获取药物定义为在过去三个月内获取所有药物，无论其获取方式（付费或免费）。使用具有稳健方差的泊松回归进行数据分析。
我们采访了414名受试者，其中大多数为女性（60.9%），平均年龄为55岁（标准差=13），且仅使用药学服务专业组成部分的一种药物（68.1%）。过去七天使用药物的依从性患病率为28.3%，免费定期获取药物的患病率为46.1%，25.7%的人无法获取所有治疗药物。在调整了药学服务专业组成部分的药物数量和连续使用的药物数量后，过去三个月内免费定期获取药物的使用者出现依从性的可能性高60%。对于有付费定期获取药物的个体，未发现获取药物与依从性之间存在关联。
免费获取药学服务专业组成部分药物的规律性对使用者的行为有影响，有助于他们坚持治疗和自我护理。药学服务专业组成部分需要进行规划，以避免获取药物不规律，这表明巴西的药物政策存在重大局限性。
