Clinical outcomes in older people of continuing or deprescribing medicines that caused a hospital admission

安全用药是老年人的一个主要健康问题。对老年人来说，与药物相关的伤害是导致住院的一个重要因素，即使开药是基于有效的证据理由。目前尚不清楚导致入院的严重药物不良反应是否意味着药物被停止或继续服用。这项研究将使用大数据来检查老年人继续服药和停药的临床效果。

Safe medicines use is a major health issue for older people. Medicine related harm is a significant factor for older people that leads to hospital admissions even if the medicine is prescribed for a valid evidence based reason. It remains unclear if a severe adverse drug effect that leads to a hospital admission should mean a medicine is stopped or continued. This research will use big data to examine the clinical effects of continuing and withdrawing medicines in older people.
