Multidisciplinary care model for geriatric patients with hip fracture in Japan: 5-year experience.

INTRODUCTION Japan is a super-aging society, the geriatric care system establishment for hip fractures is at an urgent task. This report described our concept of multidisciplinary care model for geriatric hip fractures and 5-year outcomes at the Toyama City Hospital, Japan. METHODS In this retrospective cohort study, a multidisciplinary treatment approach was applied for elderly patients with hip fracture since 2014. These patients (n = 678, males: n = 143, mean age: 84.6 ± 7.5 years), were treated per the multidisciplinary care model. Time to surgery, length of hospital stays, complications, osteoporosis treatment, mortality, and medical costs were evaluated. RESULTS The mean time to surgery was 1.7 days. Overall, 78.0% patients underwent surgery within 2 days. The mean duration of hospital stay was 21.0 ± 12.4 days. The most frequent complication was deep venous thrombosis (19.0%) followed by dysuria (14.5%). Severe complications were pneumonia 3.4%, heart failure 0.8% and pulmonary embolism 0.4%. The in-hospital mortality rate was 1.2%. The 90-day, 6-month, and 1-year mortality rates were 2.5%, 6.7%, and 12.6%, respectively. The pharmacotherapy rate for osteoporosis at discharge was 90.7%, and the continuation pharmacotherapy rate was 84.7% at 1-year follow-up. The total hospitalization medical cost per person was lower than about 400 other hospitals' average costs every year, totaled 14% less during the 5-year study period. CONCLUSION We have organized a multidisciplinary team approach for geriatric hip fracture. This approach resulted in a shorter time to surgery and hospital stay than the national average. The incidence of severe complications and mortality was low. The multidisciplinary treatment has maintained a high rate of osteoporosis treatment after discharge and at follow-up. Furthermore, the total medical cost per person was less than the national average. Thus, the multidisciplinary treatment approach for geriatric hip fractures was effective and feasible to conduct in Japan.
