What is the most frequent medication-related problem associated with hospital admission of elderly adults?

The most frequent medication-related problem associated with hospital admission of elderly adults is adverse drug events. Elderly patients are often prescribed multiple medications due to the prevalence of chronic conditions, and as a result, they are particularly vulnerable to experiencing side effects and interactions between drugs. These adverse drug events can lead to deterioration in health status, complications, and ultimately hospital admissions.

In this population, factors such as altered pharmacokinetics and pharmacodynamics due to age, potential comorbidities, and sometimes inadequate monitoring of medication regimens contribute to an increased risk of these events. Adverse drug events encompass a range of issues from side effects to allergic reactions, which can be severe enough to necessitate hospital care. Recognizing that adverse drug events are a critical factor in hospital admissions can help healthcare providers implement strategies to minimize risks, such as regular medication reviews and patient education regarding their treatment regimens.

While nonadherence, the need for additional medication therapy, and ineffective medication are also important considerations in medication management, they do not occur with the same frequency as adverse drug events in the context of hospital admissions for elderly adults.
