Loss of health related quality of life following low-trauma fractures in the elderly

Abstract

BackgroundTo estimate the long-term change in health related quality of life (HRQoL) following low-trauma fractures among individuals receiving home care (HC) services or living in long-term care (LTC) facilities using linked healthcare administrative data from Ontario, Canada.MethodsHRQoL was estimated using the Health Utility Index (HUI-2) with the InterRai Minimum Data Set (MDS), a mandatory questionnaire for LTC and HC in the province of Ontario (population 14 million). The HUI-2, a validated HRQoL instrument, allows the calculation of health utility where 0 represents death and 1 the best imaginable health state. For reference, the HUI-2 utility value for Canadians aged 80–84 years is 0.61 and the minimal clinically important difference is 0.03. The MDS was linked to Ontario acute care databases for fiscal years 2007–2011 to identify low-trauma fractures using ICD-10-CA codes. Regression models were used to identify predictors of change in HRQoL from pre-fracture levels to 3 years post fracture for several populations. Low-trauma fractures included hip, humerus, vertebral, wrist, multiple and other.ResultsTwenty-three thousand six-hundred fifty-five unique patients with low-trauma fractures were identified with pre- and post-fracture HRQoL assessments, of which 5057 individuals had at least 3 years of follow-up. Compared to patients receiving HC services (N = 3303), individuals residing in LTC (N = 1754) were older, taking more medications, and had more comorbidities. LTC patients had more hip fractures (49 % of total versus 29 %). For all fracture types, HRQoL decreased immediately following fracture. Although levels rebounded after the first month, HRQoL up to 36 months never returned to pre-fracture levels even for non-hip fracture. For both HC and LTC cohorts, clinically important and statistically significant decreases in HUI-2 utility scores were observed 36 months post fracture. Of the 6 HUI-2 domains, mobility had the largest impact on change in HRQoL. Regression analysis indicated that living with a musculoskeletal disorder or a neurological condition and living in LTC were associated with greater decrements in utility following a fracture.ConclusionsBased on the analysis of one of the largest studies on HRQoL to date, among individuals living in LTC facilities or receiving HC services, fractures have a significant permanent impact on HRQoL up to 3 years following fracture.Electronic supplementary materialThe online version of this article (doi:10.1186/s12877-016-0259-5) contains supplementary material, which is available to authorized users.

Incident Fragility Fractures Have a Long-Term Negative Impact on Health-Related Quality of Life of Older People: The Canadian Multicentre Osteoporosis Study

“…Thus, we can say that women with hip fractures failed to recover to baseline. Tarride and colleagues reported that none of the participants living in home care or long‐term care centers recovered to their baseline after 3 years postfracture for all fracture types. Notwithstanding that vertebral fractures are associated with increased mortality, we found that of the women who survived such fractures, they improved to their prefracture level after 5 years or more.…”

Incidence of Lower‐Extremity Fractures in US Nursing Homes

“…Fracture prevention strategies are important to avoid the burden of mortality and decreased quality of life for NH residents . The observed resident differences suggest nonhip LE fractures may have a different mechanism of injury than hip fractures and may occur without a fall.…”

Depression recognition and capacity for self‐report among ethnically diverse nursing homes residents: Evidence of disparities in screening

“…A standardised depression screening tool, the 9‐item Patient Health Questionnaire (PHQ‐9; Kroenke, Spitzer, & Williams, ), was introduced as a component of the minimum data set , version 3.0 ( mds 3.0) in October 2010 (Saliba & Buchanan, ). The MDS (Morris et al., ) is a set of internationally used (Chen et al., ; Tarride et al., ) instruments to conduct a comprehensive assessment of nursing home residents, and its use is federally mandated in the USA for all certified institutions receiving Medicaid and Medicare funding. Medicaid is a joint federal and state programme to assist persons with limited resources with medical costs; Medicare is a federal health insurance programme for people aged 65 and older, and for those with disabilities or end‐stage renal disease.…”
