Objective To explore the effects of "1+1+1" contracted family doctor's osteoporosis management using Internet tool.

Methods The postmenopausal female residents aged 55-70 years who signed with the first author "1+1+1" were selected, and the remaining residents were randomly set into odd-even groups according to the rules.The high-risk groups of osteoporosis were screened by OSTA as subservation subjects, in which the odd-number group was set as the control group, and the even-number group was set as the observation group.The bone mineral density(BMD) in two groups were examined by dual-energy X-ray.In accordance with the "1+1+1" contract work requirements and referring to the management experience of chronic diseases such as hypertension, the control group was given regular follow-up visits, follow-up visits, community health lectures, on-demand two-way referral and other management experience in chronic diseases such as hypertension.On the basis of the management of the control group, the observation group was given the Internet tool for online hierarchical management, targeted promotion of osteoporosis education knowledge, online answers to residents'health consultation and other online and offline management.The BMD in two groups was measured after 1 year, and the BMD results, management rate and treatment rate were compared between two groups.

Results After 1 year of intervention management in the control group, the BMD and T value of L₂ and L₄ increased compared with that before intervention(P < 0.05 to P < 0.01).In the observation group, there was no statistical significance in BMD of femoral neck, T value of femoral neck and greater trochanter between before and after intervention(P>0.05), and the differences of the increases of other observation sites were statistically significant between before and after intervention(P < 0.05 to P < 0.01).After 1 year of intervention management, the management rate in the observation group(84.00%) was higher than that of control group(72.28%) (P < 0.05), and there was no statistical significance in the treatment rate between the observation group(63.00%) and control group(54.45%)(P>0.05).

Conclusions The "1 + 1 + 1" contracted family doctor has a significant effect on the management of chronic osteoporosis, and the management advantage of Internet tool is more obvious.
