Final answer:
Hospital admissions related to medication events are often associated with polypharmacy and medication interactions, particularly among elderly patients. These can lead to adverse outcomes due to complex treatments and drug-drug interactions. Broad-spectrum antibiotics used long-term can also contribute to the development of superinfections.
Step-by-step explanation:
Among the factors often associated with hospital admissions related to medication events, C) Polypharmacy and medication interactions are particularly noteworthy. Polypharmacy refers to the use of multiple medications by a patient, which can increase the complexity of treatment and the potential for drug-drug interactions, leading to adverse drug events that may result in hospitalization. Medication interactions occur when one drug affects the efficacy or toxicity of another when taken together, which can also result in negative health outcomes. This is a significant concern, especially for elderly patients who are often prescribed multiple medications (Prescription Drugs).
For example, certain combinations of blood pressure medication with some classes of antipsychotics could result in dangerous interactions. Also, treatments such as psychotherapy, electroconvulsive therapy, and deep-brain stimulation, or taking selective serotonin reuptake inhibitors (SSRIs) might interact with other medications or have side effects that necessitate hospital care.
Additionally, the development of superinfections can be associated with the use of medications, specifically antibiotics. In particular, long-term use of broad-spectrum antimicrobials can contribute to this risk, as it can lead to the destruction of beneficial bacteria and the subsequent overgrowth of resistant organisms.
