Abstract

OBJECTIVE:

A fracture liaison service (FLS) for patients with fractures is a promising approach for improving outcomes, but barriers to the successful implementation of an FLS remain. The factors influencing the outcomes of patients already receiving FLS care are unclear.

DESIGN:

A prospective multicenter cohort study.

SETTINGS AND PARTICIPANTS:

Patients with incident hip and clinical vertebral fractures treated at 2 institutions between January 2014 and June 2016 were prospectively enrolled. Demographic profiles, comorbidities, prior fracture experiences, T scores, Fracture Risk Assessment Tool (FRAX) scores, and serum markers were examined.

MEASURES:

Self-reported functional status (at the 4th month), mortality, recurrent fractures, and falls (at the 2-year follow-up).

RESULTS:

Of 712 patients screened for eligibility, 600 (84%) participants (age 78 ± 10 years) were enrolled in the FLS program. At 4 months, 58%, 53%, and 60% of the participants reported improved mobility, self-care, and daily activities after FLS care, respectively. After 2 years, 85 (14%) died, 36 (6%) developed recurrent fractures, and 199 (33%) had 1 or more fall episodes. Multivariate logistic regression showed that neurologic disorders, heart disease, and diabetes were associated with a decreased probability of functional recovery. Cox regression showed that older age and chronic kidney disease (CKD) were predictive of increased mortality, whereas heart disease was correlated with an increased refracture risk. Older age and cancer or osteoarthritis were associated with a higher risk of falls. Importantly, a higher body mass index predicted a lower risk of mortality and a higher probability of improved self-care but a higher risk of fall at follow-up.

CONCLUSIONS/IMPLICATIONS:

We discovered that comorbidities including CKD, heart disease, cancer, and osteoarthritis could influence short-term functional changes, survival, and the risk of refractures or falls among patients participating in FLSs. These factors are expected to aid in prognosis estimation and management planning for those with fractures.
