Conclusion
To the best of our knowledge, the present study is the first to compare costs of physician- versus nurse-administered injections in a Nordic setting. Task-shifting the treatment to nurses provided a modest cost saving per injection for the hospital in addition to increased flexibility when reallocating physician resources from injections to other tasks. The societal cost per patient was not significantly different for physician- and nurse-administered injections. However, transport costs are high because of the long travel distances for patients in central Norway. Reducing transport costs by minimizing the number of clinical visits and organizing consultations and injections on the same day, may be a solution to reduce costs for society in the future.
