Fracture Liaison Services: Multidisciplinary Approaches to Secondary Fracture Prevention

A well-recognized gap exists between evidence-based recommendations for post-fracture care and actual clinical practice, demonstrated by the high percentage of fragility fracture patients who are neither diagnosed nor treated for osteoporosis. Our purpose is to review fracture liaison service (FLS) models and to evaluate national and international experiences in secondary fracture prevention. We performed a systematic search of publication databases (MEDLINE, SCOPUS) and included randomized controlled trials, meta-analyses, and review articles using the following keywords: Fracture liaison services, Secondary prevention of fracture, Post-fracture healthcare gap, and fragility fractures. References were included from 2001-2015. We subsequently performed reference searches of retrieved articles and available literature was reviewed. The efficacy of secondary fracture prevention programs correlates strongly with their intensity. Type A FLS Models are most successful in initiating diagnostic and treatment plans for fragility fracture patients. Adoption of FLS programs improves care by lowering mortality and refracture rates while also lowering healthcare costs. The quality of evidence supporting associations between FLS programs and improved outcomes was moderately strong due to the availability of longitudinal data from nationalized health systems. As our population ages and challenges to the healthcare system loom ever larger, it is imperative that we fund and champion fracture liaison services. The fracture liaison service has recently emerged as a novel clinical approach that uses coordinated, multidisciplinary care to improve post-fracture outcomes and reduce recurrent fractures. These programs are simple, targeted, high-yield and have the potential to protect our most vulnerable patients.

Own the Bone, a System-Based Intervention, Improves Osteoporosis Care After Fragility Fractures.

The goal of this study was to evaluate the effectiveness of the American Orthopaedic Association's Own the Bone secondary fracture prevention program in the United States. The objective of this quality improvement cohort study was dissemination of Own the Bone and implementation of secondary prevention (osteoporosis pharmacologic and bone mineral density [BMD] test recommendations). The main outcome measures were the number of sites implementing Own the Bone and implementation of secondary prevention, i.e., orders for BMD testing and/or pharmacologic treatment. The 177 sites participating in the program were academic and community hospitals, orthopaedic surgery groups, and a health system; data were obtained from the first 125 sites utilizing its registry, between January 1, 2010, and March 31, 2015. It included all patients, aged 50 years or older, presenting with fragility fractures (n = 23,132) who were enrolled in the Own the Bone web-based registry. The interventions were education, development of program elements, dissemination, implementation, and evaluation of the Own the Bone program at participating sites. A growing number of institutions implemented Own the Bone (14 sites in 2005-2006 to 177 sites in 2015). After consultation, 53% of patients had a BMD test ordered and/or pharmacologic therapy for osteoporosis. The Own the Bone intervention has succeeded in improving the behaviors of medical professionals in the areas of osteoporosis treatment and counseling, BMD testing, initiation of pharmacotherapy, and coordination of care for patients who have experienced a fragility fracture.

Dropping the Ball and Falling Off the Care Wagon. Factors Correlating With Nonadherence to Secondary Fracture Prevention Programs

Health care systems and hospitals in several countries have implemented Fracture Liaison Services (FLSs). Success rates of FLSs with regard to osteoporosis assessment and treatment, fracture reduction, and adherence to osteoporosis medications have been reported by several groups including ours. A significant drop-out rate among patients in these programs may occur. This has not been evaluated before. We explored the factors correlating with nonadherence among a multiethnic population of patients in the FLS at our institution, the largest tertiary teaching hospital in South East Asia. Our secondary objective was to explore whether patients who defaulted follow-up visits continued to be compliant with medications. A retrospective analysis of our FLS's computerized database was performed. Of 938 patients followed up more than 2 years, 237 defaulted at various time points. A significant percentage of patients who dropped out of the program opined that it was because the follow-up visits were too time consuming. Non-Chinese patients were more likely than Chinese (adjusted hazard ratio [aHR] = 1.98, 1.33–2.94), patients with primary school education and below were more likely than those with secondary school and above education (aHR = 1.65, 1.11–2.45) and those with nonvertebral and/or multiple fractures were more likely than those with spine fractures (aHR = 1.38, 1.06–1.81) to be nonadherent. A fraction of patients who defaulted continued to fill osteoporosis medication prescriptions. Median medication possession ratio among the patients who defaulted was 12.3% (interquartile range: 4.1%–36.7%) at 2 years. Persistence ranged from 15.1% to 20.8% and from 1.9% to 7.5% at 1 and 2 years, respectively after defaulting from the program. Our study, which to the best of our knowledge is the first of its kind, provides insight into the factors correlating with nonadherence to FLSs. Knowledge of the challenges faced by patients may be of help to health care providers interested in developing FLSs.

Predictors of re-fracture amongst patients managed within a secondary fracture prevention program: a 7-year prospective study

This 7-year prospective observational study determined the predictors of re-fracture amongst 234 patients managed within a Secondary Fracture Prevention programme. Poor compliance, multiple co-morbidities, corticosteroid therapy, low hip bone mineral density (BMD) or low body weight were all significantly associated with re-fracture in patients commenced on long-term anti-resorptive therapy. Risk factors for osteoporotic fracture amongst treatment-naïve patients are well established. In contrast, predictors of re-fracture in patients optimally managed within a Secondary Fracture Prevention (SFP) programme are ill-defined. This prospective observational study included 234 subjects with incident osteoporotic fractures managed long-term by the Concord SFP programme. Using Cox proportional hazards models, predictors of re-fracture were analysed separately for patients commenced on specific pharmacotherapy (group 1, N=171) and subjects receiving calcium and/or vitamin D supplements only (group 2, N=63). Relevant anthropometric, clinical and technical data were documented at each visit. Compliance and persistence were analysed as time-varying covariates. During a mean follow-up of 5.2 (range 3.5-7.3) years, 20.9% of all subjects re-fractured (26.3% in group 1, 6.3% in group 2). Multivariate predictors of re-fracture in group 1 were significant co-morbidity (HR 2.04 if >3, 95% CI 1.10-3.79, p=0.024), corticosteroid use (HR 1.75, 95% CI 1.12-2.73, p=0.013) and total hip BMD (HR 1.36 per 0.1 g/cm2 decrease, 95% CI 1.08-1.70, p=0.008). In contrast, gender, prevalent fractures and lumbar spine BMD were not associated with re-fracture. Amongst patients with complete compliance data, a medication possession ratio of ≤50% (HR 3.36, 95% CI 1.32-8.53, p=0.011) and low body weight (HR 1.04 per 1-kg decrease, 95% CI 1.003-1.08, p=0.032) were significantly associated with re-fracture. Amongst patients managed within a dedicated SFP programme, poor compliance, multiple co-morbidities, corticosteroid therapy, low hip BMD or low body weight are all associated with increased risk of re-fracture. This subgroup of patients therefore require intensive management including strategies to improve compliance.

Compliance and persistence to oral bisphosphonate therapy following initiation within a secondary fracture prevention program: a randomised controlled trial of specialist vs. non-specialist management

Following initiation of oral bisphosphonate therapy through a secondary fracture prevention program, 2-year treatment compliance and persistence remained high and were similar in patients randomised to follow-up by either the program or primary care physician. Thus, community-based and specialist management are equally effective in supporting compliance and persistence with anti-osteoporotic treatments. The purpose of this study was to determine whether management by a secondary fracture prevention (SFP) program (aka "fracture liaison service") results in better compliance and persistence to oral bisphosphonate therapy than follow-up by the primary care physician, after initiation within an SFP program. This prospective RCT included 102 patients with incident osteoporotic fractures referred to a SFP program in Sydney, Australia. Following oral bisphosphonate therapy initiation, patients were randomised to either 6-monthly follow-up with the SFP program (group A) or referral to their primary care physician with a single SFP program visit at 24 months (group B). Compliance and persistence to treatment were measured using pharmaceutical claims data. Predictors of compliance and persistence and associations between compliance and persistence, and changes in bone mineral density (BMD) or bone resorption marker, urinary deoxypyridinoline over 24 months were analysed. The median medication possession ratio at 24 months was 0.78 (IQR, 0.50-0.93) in group A and 0.79 (IQR, 0.48-0.96) in group B (p = 0.68). Persistence at 24 months was also similar in both groups (64 vs. 61%, respectively; p = 0.75). After adjusting for confounders, patients in group A were not more likely to be compliant (OR, 1.06; 95% CI, 0.46-2.47) or persistent (HR, 0.83; 95% CI, 0.27-1.67) than those randomised to group B. Time-based changes in BMD or bone turnover were not associated with compliance or persistence. Compliance and persistence to oral bisphosphonate therapy remain high amongst patients initiated within an SFP program, with community-based and SFP program management being equally effective in maintaining therapeutic compliance and persistence over 2 years. These results indicate that one of the main functions of an SFP program may be the initiation of therapy rather than continuous patient monitoring.

Incidence, Morbidity and Mortality in Patients Older than 50 Years with Second Hip Fracture in a Jeju Cohort Study.

PurposeAlthough the incidence of a second hip fracture is relatively well described, mortality and morbidity after a second hip fracture are seldom evaluated. The purpose of this study was to determine the incidence, morbidity, and mid-term mortality of a second hip fracture and evaluate the cause of death after a second hip fracture.Materials and MethodsInformation on patients older than 50 years, who sustained a subsequent hip fracture, were obtained from the records of eight Jeju Island hospitals between 2002 and 2011 to calculate the incidence, morbidity, and mortality of hip fractures in this age group. All patients were followed a minimum of 2 years. A systemic search for death certificates at the National Statistical Office was conducted for patients who were lost to follow-up.ResultsOf 2,055 hip fractures (419 men and 1,636 women), 98 were second hip fractures (13 men and 85 women) during the study period. The mean ages of the patients at the time of the first and second fractures were 78.8 and 80.8 years, respectively. The incidence of a subsequent hip fracture among the first hip fracture was 4.8%. Mean mortality rates at 6 months, 1 year, 2 years, and 5 years were 10.5%, 15.2%, 23.5%, and 42.0% respectively. Cumulative mortality after the second hip fracture at the 5 years follow-up was 41.8%.ConclusionOur results demonstrate that a secondary fracture prevention program is necessary to prevent second hip fractures in elderly patients.

Secondary prevention of osteoporotic fractures—an “OPTIMAL” model of care from Singapore

A significant care gap exists in the management of osteoporotic fractures. Osteoporosis Patient Targeted and Integrated Management for Active Living (OPTIMAL) is a secondary fracture prevention program instituted in the public hospitals of Singapore. We aim to describe the operational characteristics of OPTIMAL and initial audit data of patients who were recruited into the program at Singapore General Hospital. Fractures often represent the first opportunity for care of osteoporosis. However, a significant care gap still exists in the management of these sentinel events and underdiagnosis and undertreatment of osteoporotic fractures are prevalent worldwide. Fracture liaison services run by care coordinators have been shown to reduce the fracture care gap. OPTIMAL is a clinician champion-driven, case manager-run secondary fracture prevention program set up in the public hospitals of Singapore in 2008. We present the operational characteristics and initial audit data of OPTIMAL from the largest tertiary teaching hospital in Singapore. One thousand and fourteen patients have been recruited into OPTIMAL at our hospital since 2008, and 476 patients are currently in active follow-up. Two hundred and eighty-seven patients had completed a 2-year follow-up at the hospital as of August 2012 and were evaluated; 97.5% of these patients had DXA evaluation upon enrollment into the program, and 62% of the patients reported compliance with an exercise program over the 2-year follow-up. Compliance to osteoporosis medications as estimated by the medication possession ratio (MPR) was 72.8 ± 34.5% at 2 years with patients maintaining good compliance (MPR ≥ 80%) for an average of 20.2 months (95% CI 19.3-21.1). Our report provides the first compelling evidence of the potential success of a secondary fracture prevention program from an Asian country. The ultimate success of the program will be determined by fracture outcomes and cost effectiveness, but in the interim, clear evidence of enhanced assessment and treatment rates has been demonstrated.
