Retirement and nursing homes pharmacist from the supplier pharmacy contacts the home in individual cases and warns of any possible medication interactions. In the opinion of the NPM improved alignment between caregivers, general practitioners and doctors could be achieved by means of joint care visits and case reviews based on the GEMED project. This type of approach is already being applied in some nursing homes, for example in Viennese homes that discuss medication-related decisions and changes in the condition of residents in monthly interdisciplinary meetings. Optimisation of interfaces XX  It is recommended that the Federal Minister of Social Affairs, Health, Care and Consumer Protection contribute to creating a framework that facilitates, at least in phases, the implementation of the GEMED project. XX  Education in all health professions should ensure that elderly persons are not subjected to undesired adverse medical events. Orientation on the GEMED project should also be examined in this respect. 2.1.6 Heat protection measures for those in need of care and the staff The number and duration of heat waves in Austria is increasing due to global warming. Commissions were confronted with high room temperatures in several homes in Burgenland and retirement and nursing homes in Tyrol, Lower Austria and Vienna during the summer. The lack of or insufficient heat protection measures were reported in meetings. Continuously high temperatures have not only negative effects on the quality of life, but also represent a health hazard and a lethal risk for residents who are elderly and suffering from multimorbidity. A heat-related unhealthy room temperature affects staff negatively too. Superiors and home operators are also obliged to take measures to minimise job-related health hazards in the interest of their staff. Frequency and duration of heat waves is increasing The structure of care facilities determines how well they are prepared for heat waves. In terms of energy, passive cooling systems (heat storage and shade) are preferable to ensure a pleasant microclimate, for example through better ventilation or green oases. Where this is not structurally possible, there should at least be individual air-conditioned areas or the existing air conditioning system serviced, inspected and optimised. Residents have no contractual right to air conditioning. There are also no reference values for the temperature and humidity. Nevertheless, the staff in the respective home must ensure that the heat cannot become a health hazard. This is already anchored in the general duty of care designed to safeguard the dignity of the residents. Duty of care of retirement and nursing homes 38
