[Polypharmacy in nursing homes: options to improve drug therapy safety]. / Multimedikation in Einrichtungen der stationären Langzeitpflege: Möglichkeiten einer Verbesserung der Arzneimitteltherapiesicherheit (AMTS).

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.

[Instruments of official communication by regulatory authorities on risks of drug use]. / Instrumente behördlicher Kommunikation zu Anwendungsrisiken von Arzneimitteln.

Active communication of authorities, such as the Federal Institute for Drugs and Medical Devices (BfArM) and the Paul Ehrlich Institute (PEI), including maintenance of contacts with health care professionals, as well as press and public relations work, are essential prerequisites for ensuring that information on the risks of using medicinal products reaches both affected patients and healthcare professionals quickly and in a targeted manner. The various instruments of targeted communication describe possible risks and also contain recommendations that help to reduce the risk of using a medicinal product. The supplementary public relations work aims to make the tasks and objectives of the authority known to the public and to experts with the goal of creating and expanding trust in the actions of the authorities. To this end, appropriate communication platforms must be established and accepted so that they are used by both experts and the general public and the authority is perceived and appreciated as a reliable source of risk information. The currently available instruments of targeted risk communication, such as Dear Health Care Professional Communication (DHPC), risk management plans, and educational materials are described in this paper as well as broader communication on official websites or towards the media. Finally, PEI's risk communication is highlighted with particular reference to COVID-19 vaccines.
