[Polypharmacy in nursing homes: options to improve drug therapy safety]

Patients in need of care usually suffer from multiple chronic conditions and therefore receive a high number of drugs. Polypharmacy involves multiple risks, for example, drug-drug and drug-disease interactions, adverse effects and potentially inappropriate medication (PIM), more hospital admissions, and increased mortality.Residents in long-term care facilities are particularly sensitive to adverse drug reactions because of age-related changes, frailty, and the high prevalence of dementia. Numerous drugs have side effects that lead to sedation, particularly in old age, and increase the risk of falls. In addition, anticholinergic effects negatively modify cognition. These PIMs are frequently prescribed to nursing home residents.The medication process in long-term care facilities is complex and requires numerous coordinated processes. In addition to the correct administration, the nursing staff have other important tasks such as monitoring the effects and potential adverse drug reactions and communicating their observations to the prescribing physicians and home-supplying pharmacists. The nursing staff therefore play a crucial role in the prescription of psychotropic drugs and contribute to the medication quality for nursing home residents. National and international studies indicate that improvements of polypharmacy and drug therapy safety in nursing homes can only be achieved by interprofessional collaboration.
