Introduction: We derived an exhaustive operative and supervision guideline for the treatment of hip fractures from the current international and own published literature, and implemented the guidelines in our department. Methods: 1274 unselected consecutive patients admitted with a hip fracture were included, 336 of these prospectively after implementation of the new guideline. Demographic parameters, hospital treatment and re-operations were assessed from patient journals. Re-operations were recorded after six months. Results: 95% (320/336) of operative procedures were found to have followed the new guideline treatment compared to 78% (733/938) prior to its introduction (p After implementing the guideline, the rate of unsupervised junior registrars performing operations declined from 20% (188/938) to 6% (21/336, p Conclusion: An exhaustive operative guideline for hip fracture treatment can be implemented. In our case, the guideline both raised the rate of supervision and reduced the rate of reoperations.
