Background <p>Heat protection in inpatient care facilities can prevent heat-related mortality and morbidity among people in need of care and relieve the burden on nursing personnel.</p> Objective <p>The research project “Heat protection measures in inpatient and outpatient care (HISTA)”, funded by the <i>GKV-Spitzenverband </i>(Statutory Health Insurance Umbrella Organization), investigates which heat protection measures have been implemented in inpatient care facilities to date and which challenges are perceived in their implementation.</p> Methods <p>An online survey was conducted in 2024 among a&#xa0;random sample of managers of inpatient care facilities. A descriptive and statistical evaluation was carried out.</p> Results <p>A total of 282 people participated in the survey. The majority considered heat protection to be important. Heat protection measures are implemented to varying degrees. The need for support is seen particularly in the financing of technical and construction measures.</p> Discussion <p>The implementation of heat protection measures depends on the available options and resources. Heat protection should be seen as a&#xa0;task for society as a whole, which would ensure not only obligations to provide heat protection but also financing.</p>
