Most adverse events in health care are related to medication management and they are almost always preventable. Increased knowledge of patient safety related to medication management in home health care is an urgent issue to provide safe care for all patients regardless of where the health care takes place. This study explored patient safety within medication management in municipal home health care. Vignettes were used as stimulus during qualitative interviews with registered nurses. Three main themes with related subthemes were identified as challenges to patient safety within medication management in home health care: (1) challenges to information transfer, (2) challenges related to delegation, and (3) challenges of advanced medical treatments in the home. The issue of transfer of information permeated our findings. Coordinating medications, delegating tasks, along with more advanced care require clear communication between care providers to be compatible with patient safety within medication management in home health care.
