Osteoporosis prescribing in long-term care: impact of a provincial knowledge translation strategy

Increasing the uptake of vitamin D supplement use in Australian residential aged care facilities: results from the vitamin D implementation (ViDAus) study

BACKGROUND

Adequate (≥800 IU/day) vitamin D supplement use in Australian residential aged care facilities (RACFs) is variable and non-optimal. The vitamin D implementation (ViDAus) study aimed to employ a range of strategies to support the uptake of this best practice in participating facilities. The aim of this paper is to report on facility level prevalence outcomes and factors associated with vitamin D supplement use.

METHODS

This trial followed a stepped wedge cluster, non-randomised design with 41 individual facilities serving as clusters pragmatically allocated into two wedges that commenced the intervention six months apart. This multifaceted, interdisciplinary knowledge translation intervention was led by a project officer, who worked with nominated champions at participating facilities to provide education and undertake quality improvement (QI) planning. Local barriers and responsive strategies were identified to engage stakeholders and promote widespread uptake of vitamin D supplement use.

RESULTS

This study found no significant difference in the change of vitamin D supplement use between the intervention (17 facilities with approx. 1500 residents) and control group (24 facilities with approx. 1900 residents) at six months (difference in prevalence change between groups was 1.10, 95% CI - 3.8 to 6.0, p = 0.6). The average overall facility change in adequate (≥800 IU/day) vitamin D supplement use over 12 months was 3.86% (95% CI 0.6 to 7.2, p = 0.02), which achieved a facility level average prevalence of 59.6%. The variation in uptake at 12 months ranged from 25 to 88% of residents at each facility. In terms of the types of strategies employed for implementation, there were no statistical differences between facilities that achieved a clinically meaningful improvement (≥10%) or a desired prevalence of vitamin D supplement use (80% of residents) compared to those that did not.

CONCLUSIONS

This work confirms the complex nature of implementation of best practice in the RACF setting and indicates that more needs to be done to ensure best practice is translated into action. Whilst some strategies appeared to be associated with better outcomes, the statistical insignificance of these findings and the overall limited impact of the intervention suggests that the role of broader organisational and governmental support for implementation should be investigated further.

Preventing Fractures in Long-Term Care: Translating Recommendations to Clinical Practice

The Ontario Osteoporosis Strategy for long-term care (LTC) aims to support fracture risk-reduction. LTC specific recommendations for fracture prevention were developed in 2015. This article describes the use of the Knowledge-to Action framework to guide the development and application of research evidence on fracture prevention in older adults. Knowledge translation activities highlighted fractures as a significant source of morbidity in LTC, significant gaps in fracture risk assessment and treatment, and barriers and facilitators to guideline implementation. Multifaceted knowledge translation strategies, targeting staff in LTC homes in Ontario, Canada to support fracture guideline implementation have included education, audit and feedback, team-based action planning, and engagement of LTC residents, their families, and health professionals. Provincial administrative databases were accessed to monitor fracture rates between 2005 and 2015. Our research has identified enablers and barriers to knowledge use such as limited knowledge of osteoporosis, fracture risk, and prevention. Province-wide over a 10-year period, hip fracture rates in LTC decreased from 2.3% to 1.9%, and any fracture rates decreased from 4% to 3.6%. This body of work suggests that multifaceted knowledge translation initiatives are feasible to implement in LTC and can improve the uptake of clinical recommendations for fracture prevention. A key aspect of our fracture prevention knowledge translation activities has been the full engagement of key stakeholders to assist in the co-development and design of knowledge translation products.

Process outcomes of a multifaceted, interdisciplinary knowledge translation intervention in aged care: results from the vitamin D implementation (ViDAus) study

BACKGROUND

Vitamin D supplement use is recommended best practice in residential aged care facilities (RACFs) for the prevention of falls, however has experienced delays in uptake. Following successful international efforts at implementing this evidence into practice, the ViDAus study sought to replicate this success for the Australian context. The aim of this paper is to report on the process outcomes of implementing this intervention.

METHODS

Forty-one RACFs were engaged in a multifaceted, interdisciplinary knowledge translation intervention. This focused on raising awareness to improve knowledge on vitamin D, and supporting facilities to identify barriers and implement locally devised strategies to improve the uptake of evidence based practice (EBP).

RESULTS

Staff members of participating facilities (n = 509 including nursing, care and allied health staff) were well engaged and accepting of the intervention, though engagement of servicing general practitioners (GPs) (n = 497) and pharmacists (n = 9) was poor. Facilities each identified between three and eight strategies focused on raising awareness, identifying residents to target for vitamin D and creating referral pathways depending upon their own locally identified barriers and capacity. There was variable success at implementing these over the 12-month intervention period. Whilst this study successfully raised awareness among staff, residents and their family members, barriers were identified that hindered engagement of GPs.

CONCLUSIONS

The intervention was overall feasible to implement and perceived as appropriate by GPs, pharmacists, facility staff, residents and family members. More facilitation, higher-level organisational support and strategies to improve RACF access to GPs however were identified as important improvements for the implementation of vitamin D supplement use.

Validation of a one year fracture prediction tool for absolute hip fracture risk in long term care residents

BACKGROUND

Frail older adults living in long term care (LTC) homes have a high fracture risk, which can result in reduced quality of life, pain and death. The Fracture Risk Scale (FRS) was designed for fracture risk assessment in LTC, to optimize targeting of services in those at highest risk. This study aims to examine the construct validity and discriminative properties of the FRS in three Canadian provinces at 1-year follow up.

METHODS

LTC residents were included if they were: 1) Adults admitted to LTC homes in Ontario (ON), British Columbia (BC) and Manitoba (MB) Canada; and 2) Received a Resident Assessment Instrument Minimum Data Set Version 2.0. After admission to LTC, one-year hip fracture risk was evaluated for all the included residents using the FRS (an eight-level risk scale, level 8 represents the highest fracture risk). Multiple logistic regressions were used to determine the differences in incident hip or all clinical fractures across the provinces and FRS risk levels. We examined the differences in incident hip or all clinical fracture for each FRS level across the three provinces (adjusted for age, BMI, gender, fallers and previous fractures). We used the C-statistic to assess the discriminative properties of the FRS for each province.

RESULTS

Descriptive statistics on the LTC populations in ON (n = 29,848), BC (n = 3129), and MB (n = 2293) are: mean (SD) age 82 (10), 83 (10), and 84 (9), gender (female %) 66, 64, and 70% respectively. The incident hip fractures and all clinical fractures for FRS risk level were similar among the three provinces and ranged from 0.5 to 19.2% and 1 to 19.2% respectively. The overall discriminative properties of the FRS were similar between ON (C-statistic = 0.673), BC (C-statistic = 0.644) and MB (C-statistic = 0.649) samples.

CONCLUSION

FRS is a valid tool for identifying LTC residents at different risk levels for hip or all clinical fractures in three provinces. Having a fracture risk assessment tool that is tailored to the LTC context and embedded within the routine clinical assessment may have significant implications for policy, service delivery and care planning, and may improve care for LTC residents across Canada.

Osteoporosis in Older Persons: Old and New Players

Osteoporosis is the most common bone disease in humans. Older persons are at higher risk of osteoporotic fractures that also result in poor quality of life, disability, loss of independence, institutionalization, and higher mortality. Osteoporosis shares a distinct pathophysiologic relationship with sarcopenia, an age-related disease comprising declines in muscle mass, strength, or function. The combination of these two diseases is known as osteosarcopenia. Understanding the pathophysiology of osteosarcopenia, in addition to its diagnostic and therapeutic approaches, is key in providing older adults with the best falls and fractures prevention strategies. This review provides updated information on new discoveries on the combined pathophysiology of osteoporosis and sarcopenia that have led to the development of novel therapeutic approaches. New recommendations for the use of risk calculators and densitometry are also presented in this review as well as evidence on current and upcoming pharmacologic treatments to prevent falls and fractures in older persons.

Development and validation of the Fracture Risk Scale (FRS) that predicts fracture over a 1-year time period in institutionalised frail older people living in Canada: an electronic record-linked longitudinal cohort study

OBJECTIVES

To develop and validate our Fracture Risk Scale (FRS) over a 1-year time period, using the long-term care (LTC) Resident Assessment Instrument Minimum Data Set Version 2.0 (RAI-MDS 2.0).

DESIGN

A retrospective cohort study.

SETTING

LTC homes in Ontario, Canada.

PARTICIPANTS

Older adults who were admitted to LTC and received a RAI-MDS 2.0 admission assessment between 2006 and 2010.

RESULTS

A total of 29 848 LTC residents were enrolled in the study. Of these 22 386 were included in the derivation dataset and 7462 individual were included in the validation dataset. Approximately 2/3 of the entire sample were women and 45% were 85 years of age or older. A total of 1553 (5.2%) fractures were reported over the 1-year time period. Of these, 959 (61.8%) were hip fractures. Following a hip fracture, 6.3% of individuals died in the emergency department or as an inpatient admission and did not return to their LTC home. Using decision tree analysis, our final outcome scale had eight risk levels of differentiation. The percentage of individuals with a hip fracture ranged from 0.6% (lowest risk level) to 12.6% (highest risk level). The area under the curve of the outcome scale was similar for the derivation (0.67) and validation (0.69) samples, and the scale exhibited a good level of consistency.

CONCLUSIONS

Our FRS predicts hip fracture over a 1-year time period and should be used as an aid to support clinical decisions in the care planning of LTC residents. Future research should focus on the transformation of our scale to a Clinical Assessment Protocol and to assess the FRS in other healthcare settings.

Treatment of Osteoporosis in Australian Residential Aged Care Facilities: Update on Consensus Recommendations for Fracture Prevention

BACKGROUND

Older people living in residential aged care facilities (RACFs) are at a higher risk of suffering fractures than the community-dwelling older population. The first Consensus Conference on Treatment of Osteoporosis in RACFs in Australia, held in Sydney in July 2009, aimed to address some of the issues relating to the treatment of older residents with osteoporosis in RACFs. Considering that the field of osteoporosis diagnosis and management has significantly advanced in the last 5 years and that new evidence has been generated from studies performed within RACFs, a Second Consensus Conference was held in Sydney in November 2014.

METHODS

An expert panel met in November 2014 in Penrith, NSW, Australia in an attempt to reach a consensus on diverse issues related to the treatment of osteoporosis at RACFs. Participants were selected by the scientific committee on the basis of their practice in an RACF and/or major published articles. The co-chairs distributed topics randomly to all participants, who then had to propose a statement on each topic for approval by the conference after a short, evidence-based presentation, when possible.

RESULTS

This article provides an update on the most relevant evidence on osteoporosis in older people living in RACFs graded according to its level, quality, and relevance.

CONCLUSION

As with the first consensus, it is hoped that this statement will constitute an important guide to aid physicians in their decision making while practicing at RACFs.

Comparative trends in incident fracture rates for all long-term care and community-dwelling seniors in Ontario, Canada, 2002-2012

SUMMARY

In this population-based study, we compared incident fracture rates in long-term care (LTC) versus community seniors between 2002 and 2012. Hip fracture rates declined more rapidly in LTC than in the community. An excess burden of fractures occurred in LTC for hip, pelvis, and humerus fractures in men and hip fractures only in women.

INTRODUCTION

This study compares trends in incident fracture rates between long-term care (LTC) and community-dwelling seniors ≥65 years, 2002-2012.

METHODS

This is a population-based cohort study using administrative data. Measurements were age/sex-adjusted incident fracture rates and rate ratios (RR) and annual percent change (APC).

RESULTS

Over 11 years, hip fracture rates had a marked decline occurring more rapidly in LTC (APC, -3.49 (95% confidence interval (CI), -3.97, -3.01)) compared with the community (APC, -2.93 (95% CI, -3.28, -2.57); p < 0.05 for difference in slopes). Humerus and wrist fracture rates decreased; however, an opposite trend occurred for pelvis and spine fractures with rates increasing over time in both cohorts (all APCs, p < 0.05). In 2012, incident hip fracture rates were higher in LTC than the community (RRs: women, 1.55 (95% CI, 1.45, 1.67); men, 2.18 (95% CI, 1.93, 2.47)). Higher rates of pelvis (RR, 1.48 (95% CI, 1.22, 1.80)) and humerus (RR, 1.40 (95% CI, 1.07, 1.84)) fractures were observed in LTC men, not women. In women, wrist (RR, 0.76 (95% CI, 0.71, 0.81)) and spine (RR, 0.52 (95% CI, 0.45, 0.61)) fracture rates were lower in LTC than the community; in men, spine (RR, 0.75 (95% CI, 0.57, 0.98) but not wrist fracture (RR, 0.91 (95% CI, 0.67, 1.23)) rates were significantly lower in LTC than the community.

CONCLUSION

Previous studies in the community have shown declining hip fracture rates over time, also demonstrated in our study but at a more rapid rate in LTC. Rates of humerus and wrist fractures also declined. An excess burden of fractures in LTC occurred for hip fractures in women and for hip, pelvis, and humerus fractures in men.
