Effect of Orthogeriatric Co-Management on Geriatric Hip Fractures in China

Although geriatric hip fracture is a serious public health problem in China, the result of orthogeriatric co-management (OGC) is rarely reported. This study aimed to evaluate the effect of OGC in Chinese patients aged ≥65 years.

In this single-centre, pre-post intervention, retrospective study, traditional orthopaedic care (TOC) was used until OGC was implemented in May 2015, a multidisciplinary team was organized, and clinical protocol was designed. Consecutive hip fracture patients who were ≥65 years and injured within 3 weeks were included in this study. Demographic characteristics, comorbidities, fracture patterns, surgical procedure, time to surgery, length of hospital stay, inpatient complications, and in-hospital mortality were extracted and examined. At 1-year after surgery, data on patients' mobility and mortality were collected. The time to surgery, incidence of inpatient complications, mortality and functional outcomes were compared between the groups.

There were no significant differences in sex, fracture type, and surgical pattern between OGC (n = 434) and TOC (n = 452) groups. Patients in OGC group were significantly older (P < 0.001) and had a higher age-adjusted Charlson comorbidity index (P < 0.001). However, waiting time between admission and operation was significantly lower in OGC group (P < 0.001). There was no significant difference in the mortality rate at the time of the patient being in-hospital and at 1, 3, and 6 months after surgery. Although 1-year mortality was higher in OGC group (P = 0.036), Cox regression analysis showed no significant correlation of OGC with 1-year mortality. There was no significant difference in pre-injury mobility and 1-year follow-up mobility assessed by Parker score. Only approximately half of the patients in both groups completely returned to their pre-injury mobility level.

OGC significantly shortens time to surgery for geriatric hip fractures compared with TOC. However, there is no significant effect on mortality rate within 1 year and functional status at 1 year of follow-up.
