Polypharmacy is a concern in the practice of geriatrics because of consequences such as adverse drug events and poorer quality of life. Deprescribing, a response to polypharmacy, refers to the systematic, programmed, and appropriate reduction in drug number and dose. Although now broadly recognized, challenges exist in practice for effective implementation. This study was conducted to determine the deprescribing success rate and relate it to drug classes and clinical settings, and to identify factors that influence the deprescribing process.
As a performance improvement (PI) project, fellows in geriatric medicine, under supervision of faculty geriatricians, attempted deprescribing during at least 1 encounter daily at 2 long-term care (LTC) facilities and an outpatient geriatrics clinic (C) in Bronx, New York, from August 2018 to January 2019. Deprescribing was initiated following discussion and consent from patient or caregiver. Following the data collection, involved fellows and faculty physicians participated in a survey to identify factors that influenced the process.
Out of 449 encounters, 383 encounters were included for analysis. Average patient age was 78.2 years (LTC: 77.9, C: 79.1). Average patient comorbidities was 6.5 (LTC: 6.7, C: 5.8). Deprescribing was successful in 90.1% of encounters (LTC: 96.9%, C: 67.4%). On average, 1.3 medications were deprescribed per encounter (LTC: 1.4, C: 1.0). Analgesics (32.2%), multivitamin-minerals supplements (29.7%), lipid-lowering agents (22.9%), antihistamines (46.7%), and acid blockers (26.2%) had highest success.
Deprescribing is possible in practice in both LTC and community settings at each encounter, until it is no longer applicable. Factors that contribute to successful deprescribing primarily include meaningful and earnest provider effort, ideally in collaboration with interdisciplinary team members (nurses, pharmacists, social worker, and others), besides interactions with consultants for the patient. Certain medication classes such as vitamins, minerals, analgesics, and proton pump inhibitors can be deprescribed with high success, as noted in our study, whereas antipsychotic agents, antidepressants, and ophthalmic preparations, prescribed by specialists, proved harder to deprescribe. An understanding of barriers to deprescribing (outlined in the article) and addressing them are crucial in enabling success. The study demonstrates that as a performance improvement project in collaborative effort with multiple disciplines, deprescribing is possible in health care. Factors promoting success and barriers to deprescribing are detailed. Appropriate deprescribing has the potential to help lower adverse drug events, costs of care, and possibly improve quality of life.
由于药物不良事件和生活质量下降等后果,老年人医学实践中存在药物滥用问题。药物减量是对药物滥用的一种反应,指的是有系统、有计划、适当地减少药物的种类和剂量。尽管现在已经得到广泛认可,但在实践中有效实施仍存在挑战。本研究旨在确定药物减量的成功率,并将其与药物类别和临床环境联系起来,同时确定影响药物减量过程的因素。
作为一项绩效改进(PI)项目,老年医学研究员在纽约布朗克斯的 2 家长期护理机构(LTC)和 1 家门诊老年医学诊所(C)的至少 1 次日常就诊中,在老年医学医生的监督下,尝试进行药物减量。在与患者或护理人员讨论并征得同意后,开始进行药物减量。在数据收集后,参与的研究员和医生参加了一项调查,以确定影响该过程的因素。
在 449 次就诊中,有 383 次就诊被纳入分析。患者平均年龄为 78.2 岁(LTC:77.9 岁,C:79.1 岁)。患者平均合并症为 6.5 种(LTC:6.7 种,C:5.8 种)。90.1%的就诊实现了药物减量成功(LTC:96.9%,C:67.4%)。每次就诊平均减少 1.3 种药物(LTC:1.4 种,C:1.0 种)。镇痛药(32.2%)、多种维生素矿物质补充剂(29.7%)、降脂药(22.9%)、抗组胺药(46.7%)和酸阻滞剂(26.2%)的减量成功率最高。
在 LTC 和社区环境中,每次就诊都有可能成功进行药物减量,直到不再适用为止。有助于药物减量成功的因素主要包括有意义和认真的提供者努力,理想情况下是与跨学科团队成员(护士、药剂师、社会工作者等)合作,此外还与患者的顾问进行互动。我们的研究表明,某些药物类别,如维生素、矿物质、镇痛药和质子泵抑制剂,可实现高成功率的药物减量,而精神科药物、抗抑郁药和眼科制剂等专科医生开具的药物则较难进行药物减量。了解药物减量的障碍(文章中列出)并加以解决对于实现成功至关重要。该研究表明,作为与多个学科合作的绩效改进项目,医疗保健中可以进行药物减量。详细说明了促进成功的因素和药物减量的障碍。适当的药物减量有可能有助于降低药物不良事件、医疗成本,并可能改善生活质量。
