There is neither a "gold standard" nor commonly approved therapy goals in postoperative pain therapy. In amulti-center study, more than 80% of all patients treated stated that they suffered from postoperative pain. Moreover, patients evaluated the pain therapy as significantly worse than other medical or nursing practices. Therefore, there is aneed for optimization in therapy for acute pain. The goal of our project was to figure out if the introduction of a"pain treatment standard" would increase the satisfaction of patients, physicians, and nurses, and reduce the costs of pain-related medicine. Overall, 2769 patients and 285 providers (202 nurses and 83physicians) were polled. The medication costs in ten areas of the ward were evaluated and compared. The providers were offered atraining course on the "pain standard" and it was officially introduced onto the wards. After some time, the satisfaction of patients and providers and the use of medicine were recorded again. The maximum pain values declared by the patients significantly decreased after the introduction of the "pain standard." The satisfaction with pain therapy significantly increased for the patients and for the providers. The reported minimum pain values of the patients did not change significantly. The costs of pain medicine slightly increased. In general, there was apositive effect of introducing a"pain standard" for patients and providers.
