Brief summary: This is a study to improve the collaboration between primary and secondary health care on the treatment of osteoporosis after a hip fracture. In Akershus University Hospital, patients 75 years or older with a hip fracture, are offered treatment with an infusion of zoledronic acid 5mg, combined with vitamin D and calcium supplements, to prevent new fractures. General practitioners (GPs) are requested to take care of the follow-up on this treatment with annual infusions of zoledronic acid for 3 years.

In the opinion of the investigators, it is expedient, safe, and sensible for parts of the subsequent treatment to be provided by GPs. If hospitals take responsibility for initiating the treatment, the investigators believe that most of the subsequent monitoring and continuance of treatment can be conducted by the primary healthcare service. Despite this, the investigators suspect that many patients do not get their annual infusions of zoledronic acid after discharge from the hospital.

This quality assurance study aims to test a new system where ambulant nurses from the hospital support the GP in treating osteoporosis with the administration of zoledronic acid in the following 3 years after femoral neck fractures. Through the project, the investigators will create procedures for the administration and follow-up of zoledronic acid fitted in the setting of the GP office.

The design is a cluster randomized controlled study (RCT) where the regions are prospectively randomized to either intervention or control regions. Patients ≥ 75 years, which suffer a femoral neck fracture, are identified in our Department of Orthopedic Surgery, where they are provided the first infusion of zoledronic acid 5 mg and proposed participation in the study. Patients from the intervention regions will be followed by the protocol of ambulant nurse-assisted administration of zoledronic acid. Patients from the control regions are offered the usual care. Both patients from the control and intervention regions are asked to fill out a questionnaire after 1 year. The questionnaire will ask if the patient has got zoledronic acid as encouraged in the medical journal after discharge from the hospital. The primary study outcome is if the patients are offered treatment at a one-year follow-up or not.

Sample size calculation estimates a total sample of 130 patients based on a minimal clinically important difference of 20% follow-up between the groups. Because of high mortality, the investigators estimate the need for 200 patients.

The investigators hypothesize that the one-year follow-up is better in the intervention group than in the control group.
