Drug Therapy Safety in Outpatient Care Services

Introduction Due to frequent multi-medication, older people are particularly vulnerable to adverse drug reactions (ADRs), which increase hospitalisation and mortality rates. If specially trained pharmacists and nursing staff assume more responsibility in the use of medicines by the elderly, risks can be avoided. Methods A voluntary survey was conducted with care managers of ambulatory care services using a predefined survey questionnaire, and the medicines stored and provided were examined. Results Medicines were stored in 76% of the 104 ambulatory care services surveyed. In 63% of these, medicines in stock were examined, and in 55% a comparison was made between prescribed and provided medicines. Deficiencies were found in about half of the inspected boxes and dosettes. On average, 1.5 errors were found per checked unit; 40% of the nursing services left the medicines in the vehicle for 3 to 6 hours when transporting them to the client. Regular meetings with doctors' practices or pharmacies were conducted by less than 35% of the these services. In 41 out of the 104 services surveyed, investigators monitoring therapy rated the performance of the nursing staff positively. Conclusions Therapy monitoring and cooperation of ambulatory care services with other health professionals, especially with pharmacists, needs to be improved. More care and control (e. g., through the four-eyes principle) should be exercised, especially in the provision of medicines. In future, further precisely conducted and representative surveys on medication processes in outpatient care need to be carried out. Analogous to existing studies, there were indications of quality and communication problems as well as weaknesses in therapy monitoring in ambulatory care services. Sources of error were mainly found in storage and transport of medicines. Errors were also evident in the provision of medicines. Due to the lack of participation obligations, the results of the study are limited.
