There is a need for reproducible methods to measure over-the-counter (OTC) medication possession and use. This is because OTC medications are self-managed, variably monitored by healthcare professionals, and in certain populations such as older adults some OTC medications may introduce risk and cause more harm than benefit. (s): To develop and assess the feasibility of the Home Medication Inventory Method (HMIM), a novel method to measure possession and use of OTC medications. We benchmarked, adapted, and standardized prior approaches to medication inventory to develop a method capable of addressing the limitations of existing methods. We then conducted a pilot study of the HMIM among older adults. Eligible participants were aged ≥60 years, reported purchasing or considering purchasing OTC medication, and screened for normal cognition. Interviews were conducted both in person and remotely. When possible, photographs of all OTC medications were obtained with participant consent and completion times were recorded for both in-person and remote modalities. In total 51 participants completed the pilot study. Home medication inventories were conducted in-person (n = 15) and remotely (n = 36). Inventories were completed in a mean (SD) of 20.2 min (12.7), and 96 % of inventories completed within 45 min. A total of 390 OTC medications were possessed by participants, for a mean (SD) of 7.6 (6.3) per participant. No differences in duration of interviews or number of medications reported were identified between in-person and remote modalities. Anticholinergic medications, a class targeted in the pilot as potentially harmful to older adults, were possessed by 31 % of participants, and 14 % of all participants reported use of such a medication within the previous 2 weeks. Implementing the HMIM using in-person and remote modalities is a feasible and ostensibly reproducible method for collecting OTC medication possession and use information. Larger studies are necessary to further generalize HMIM feasibility and reliability in diverse populations.

评估非处方药（OTC）持有和使用的家庭药物库存方法：针对老年人面对面和远程方式可行性的试点研究

需要可重复的方法来衡量非处方 (OTC) 药物的持有和使用。这是因为非处方药是自我管理的，由医疗保健专业人员进行不同程度的监测，并且在某些人群（例如老年人）中，一些非处方药可能会带来风险，造成的弊大于利。(s)：开发和评估家庭药物库存方法 (HMIM) 的可行性，这是一种衡量 OTC 药物拥有和使用情况的新方法。我们对先前的药物库存方法进行了基准测试、调整和标准化，以开发一种能够解决现有方法局限性的方法。然后，我们对老年人进行了 HMIM 试点研究。符合资格的参与者年龄≥60岁，报告购买或考虑购买非处方药，并筛查正常认知。采访以面对面和远程方式进行。如果可能，所有非处方药的照片均在参与者同意的情况下获得，并记录了现场和远程方式的完成时间。共有 51 名参与者完成了试点研究。家庭药物库存分为现场（n = 15）和远程（n = 36）两种。库存的平均完成时间 (SD) 为 20.2 分钟 (12.7)，96% 的库存在 45 分钟内完成。参与者总共拥有 390 种非处方药，每位参与者的平均 (SD) 为 7.6 (6.3)。面对面和远程方式之间的访谈持续时间或报告的药物数量没有差异。抗胆碱能药物是试点中对老年人潜在有害的一类药物，31% 的参与者拥有抗胆碱能药物，所有参与者中有 14% 的人报告在过去两周内使用过此类药物。使用面对面和远程方式实施 HMIM 是收集 OTC 药物拥有和使用信息的可行且表面上可重复的方法。需要进行更大规模的研究来进一步推广 HMIM 在不同人群中的可行性和可靠性。
